compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. 
The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem 
all your shares at the end of those periods. The example also assumes that your investment has a 5% return 
each year and that the Fund&#x2019;s operating expenses, before fee waivers and/or expense reimbursements, 
remain the same. The example assumes that the Fund&#x2019;s fee waiver and/or expense reimbursement arrangements 
will each remain in place for the durations noted in the table above. Although your actual costs may 
be higher or lower, based on these assumptions your costs would be:&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Class I shares of other Nuveen mutual funds and in other investment pools or investment products, including 
other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;advised 
by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). The Fund invests in Underlying Funds 
according to a relatively stable asset allocation strategy that will not gradually adjust over time and 
is designed for investors who are already in retirement (i.e., have already passed their retirement year) 
and may have begun taking systematic withdrawals upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management 
currently expects to allocate approximately 35.00% of the Fund&#x2019;s assets to equity Underlying Funds, 
60.00% of its assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying 
Funds. These allocations represent targets for equity, fixed-income and direct real estate asset classes. 
Target allocations may be changed and actual allocations may vary up to ten percentage points from the 
targets. Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management 
allocates the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, 
fixed-income, non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real 
estate) represented by various Underlying Funds. These market sector allocations may vary by up to 10% 
from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current target market sector 
allocations for June 30, 2026 which may change, are approximately as follows: U.S. Equity: 22.75%; International 
Equity: 12.25%; Fixed-Income: 34.51%; Non-USD Fixed-Income: 5.50%; Short-Term Fixed-Income: 10.00%; Inflation-Protected 
Assets: 10.00%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future allocations if Nuveen Asset Management believes that such Underlying 
Funds and/or market sectors are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders, 
and the portfolio management team may use tactical allocation to take advantage of short to intermediate 
term opportunities through a combination of positions in Underlying Funds. If 10% or more of the Fund&#x2019;s 
assets are expected to be invested in any Underlying Fund or market sector not listed above, shareholders 
will receive prior notice of such change. Investors should note that the Fund has a significant level 
of equity exposure and this exposure could cause fluctuation in the value of the Fund depending on the 
performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to 
invest in other investment pools or investment products noted above, the Fund may invest in ETFs and 
exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities in 
order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash management, 
hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with the types of 
securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, 
will also be subject to the general risks of fixed-income securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The 
Fund&#x2019;s asset class allocations, market sector allocations within each asset class, and Underlying 
Fund allocations within each market sector, as of June 30, 2025, are listed in the chart below. The Fund 
has relatively fixed asset allocations that will not gradually adjust over time. Underlying Fund allocations 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements: (i) the addition of Nuveen Small Cap Select Fund and 
Nuveen International Value Fund as new Underlying Funds in the U.S. Equity and International Equity market 
sectors, respectively, and corresponding reductions in allocations to other Underlying Funds in those 
market sectors; (ii) the addition of Nuveen Floating Rate Income Fund as a new Underlying Fund in the 
Fixed-Income market sector and corresponding reductions in allocations to other Underlying Funds in that 
market sector; (iii) the redesignation of Nuveen Emerging Markets Debt Fund and Nuveen &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;International 
Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income market sector; and (iv) 
strategic reallocations among certain Underlying Funds.&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign 
securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities 
less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;measures that may be imposed could vary broadly in scope, and their impact is 
impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- 
and mid-cap risk&#x2014;The risk that the stocks of small-capitalization companies often experience greater 
price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, including rates that fall below zero, or a lack of market participants 
may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making 
it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values 
of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income 
securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile 
but may provide lower returns than fixed-income securities with longer durations or maturities. Other 
factors that may affect the &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;value of debt securities include, but are not limited to, economic, political,

securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, 
political, regulatory, currency, market or economic developments as well as armed conflicts. These developments 
may impact the ability of a foreign debt issuer to make &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The risk that, during periods of falling interest

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in more developed countries and may be more vulnerable to market manipulation.

following chart and table help illustrate some of the risks of investing in the Fund by showing changes 
in the Fund&#x2019;s performance from year to year. The bar chart shows the annual total returns of the 
Retirement Class of the Fund, before taxes, in each full calendar year for the last ten years. Because 
the expenses vary across share classes, the performance of the Retirement Class may vary from the other 
share classes. Below the bar chart are the best and worst returns of the Retirement Class for a calendar 
quarter during the full calendar-year periods covered by the bar chart. The performance table following 
the bar chart shows the Fund&#x2019;s average annual total returns for the Retirement, Class A, Class 
I, Premier and Class R6 classes over the applicable one-year, five-year, ten-year and since-inception 
periods ended December 31, 2024, and how those returns compare to those of a broad-based securities market 
index and a composite index that represents the market sectors in which the Fund invests across the equity 
and fixed-income asset classes. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) 
served as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class 
shares, and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, 
expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For current performance information of each share class, including performance

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee

Class I shares of other Nuveen mutual funds and in other investment pools or investment products, including 
other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, 
Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen 
Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the 
&#x201c;Underlying Funds&#x201d;). In general, the Fund is designed for investors who have an approximate 
target retirement year in mind, and the Fund&#x2019;s investments are adjusted from more aggressive to 
more conservative over time as the Fund&#x2019;s target retirement year approaches and for approximately 
30 years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed 
for investors who retired in, or planned to retire within a few years of, 2010 and may have begun taking 
systematic withdrawals upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects

66.00% of its assets to fixed-income Underlying Funds and 2.00% of its assets to direct real estate Underlying 
Funds. These allocations represent targets for equity, fixed-income and direct real estate asset classes. 
Target allocations will change over time and actual allocations may vary up to ten percentage points 
from the targets. The target allocations along the investment glidepath, illustrated in the chart below, 
gradually become more conservative. The Fund had target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2010 (the direct real estate asset class was 
added in 2017) and will reach the Fund&#x2019;s final target allocation of approximately 20.00% equity/80.00% 
fixed-income/0.00% direct real estate in 2040. Within the equity, fixed-income and direct real estate 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, short-term fixed-income, inflation-protected 
assets and direct real estate) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 20.80%; International Equity: 11.20%; Fixed-Income: 34.51%; Non-USD Fixed-Income: 
5.50%; Short-Term Fixed-Income: 16.00%; Inflation-Protected Assets: 10.00%; and Direct Real Estate: 2.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target

Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant Small Cap Equity Fund, Nuveen Quant Small/Mid 
Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend Value Fund, Nuveen Growth Opportunities

in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds within 
a market sector may be changed at any time without notice to shareholders, and the portfolio management 
team may use tactical allocation to take advantage of short to intermediate term opportunities through 
a combination of positions in Underlying Funds. If 10%&#160;or more of the Fund&#x2019;s assets are expected 
to be invested in any Underlying Fund or market sector not listed above, shareholders will receive prior 
notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to 
invest in other investment pools or investment products noted above, the Fund may invest in ETFs and 
exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities in 
order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash management, 
hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with the types of 
securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, 
will also be subject to the general risks of fixed-income securities, including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The 
Fund&#x2019;s asset class allocations, market sector allocations within each asset class, and Underlying 
Fund allocations within each market sector, as of June 30, 2025, are listed in the chart below. These 
allocations will change over&#160;time. Underlying Fund allocations in particular may change from year 
to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management expects that

Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Fund which has also reached its final target allocation or other similar fund 
designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, 
market or economic developments as well as armed conflicts and can result in greater price volatility 
and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging 
or developing markets. Foreign investments may also have lower liquidity and be more difficult to value 
than investments in U.S. issuers. To the extent a Fund invests a significant portion of its assets in 
the securities of companies in a single country or region, it may be more susceptible to adverse economic, 
market, political or regulatory events or conditions affecting that country or region. Foreign investments 
may also be subject to risk of loss because of more or less foreign government regulation, less public 
information, less stringent investor protections and less stringent accounting, corporate governance, 
financial reporting and disclosure standards. Changes in the value of foreign currencies may make the 
return on an investment increase or decrease, unrelated to the quality or performance of the investment 
itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, 
trade restrictions (including tariffs) and other restrictions by the United States or other governments 
may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental 
actions or developments could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability 
to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make 
a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more difficult to value. The 
type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and 
their impact is impossible to&#160;predict;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of

resources, products and markets. Securities of small-cap companies often have lower overall liquidity 
than securities of larger companies as a result of there being a smaller market for their securities, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization 
companies often experience greater price volatility, lower trading volume and lower overall liquidity

as well as risks related to the fixed-income markets in general, such as:&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;interest rate risk&#x2014;The 
risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, including rates that fall below zero, or a lack of market participants 
may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making 
it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values 
of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income 
securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile 
but may provide lower returns than fixed-income securities with longer durations or maturities. Other 
factors that may affect the value of debt securities include, but are not limited to, economic, political, 
public health, and other crises and responses by governments and companies to such crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

securities or financial instruments of foreign issuers involves increased risks due to adverse issuer,

may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations 
to a Fund or impair a Fund&#x2019;s ability to enforce its rights against the foreign debt issuer. These

of loss because of more or less foreign government regulation, less public information, less stringent 
investor protections and less stringent accounting, corporate governance, financial reporting and disclosure

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject 
to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal 
remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability 
to enforce certain regulatory or legal obligations or otherwise bring actions against bad actors in emerging 
market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full calendar-year periods covered by the bar chart. The performance table following the bar chart 
shows the Fund&#x2019;s average annual total returns for the Retirement, Class I, Premier and Class R6 
classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index that represents the market sectors in which the Fund invests across the equity and fixed-income 
asset classes. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;who 
retired in, or planned to retire within a few years of, 2015 and may have begun taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
34.50% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 61.00% of its 
assets to fixed-income Underlying Funds and 4.50% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative. The Fund had target allocations of approximately 50.00% equity/50.00% fixed-income 
in the Fund&#x2019;s target retirement year of 2015 (the direct real estate asset class was added in 2017) 
and will reach the Fund&#x2019;s final target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% 
direct real estate in 2045. Within the equity, fixed-income and direct real estate asset classes, Nuveen 
Asset Management allocates the Fund&#x2019;s investments to particular market sectors (U.S. equity, international 
equity, fixed-income, non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct 
real estate) represented by various Underlying Funds. These market sector allocations may vary by up 
to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current target market 
sector allocations for June 30, 2026, which will change over time, are approximately as follows: U.S. 
Equity: 22.43%; International Equity: 12.08%; Fixed-Income: 34.51%; Non-USD Fixed-Income: 5.50%; Short-Term 
Fixed-Income: 11.00%; Inflation-Protected Assets: 10.00%; and Direct Real Estate: 4.50%. The asset class 
and market sector names used herein are intended to reflect the primary type of investment of the Underlying 
Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector 
allocations to Underlying Funds may include the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, 
Nuveen Large Cap Value Fund, Nuveen Quant Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, 
Nuveen Dividend Growth Fund, Nuveen Dividend Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small 
Cap Select Fund (U.S. Equity); Nuveen Emerging Markets Equity Fund, Nuveen International Equity Fund, 
Nuveen International Opportunities Fund, Nuveen International Value Fund and Nuveen Quant International 
Small Cap Equity Fund (International Equity); Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen 
Floating Rate Income Fund and Nuveen High Yield Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund 
and Nuveen International Bond Fund (Non-USD Fixed-Income); Nuveen Money Market Fund and Nuveen Short 
Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets); 
and Nuveen Real Property Fund LP (Direct Real Estate). Nuveen Real Property Fund LP is a private fund, 
which is not available for investment by the general public; it is currently offered exclusively to investment 
pools or investment products managed by Nuveen Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:14.0pt; font-family:Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;img alt="" src="img_dd6ef26623744f1.jpg"/&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund is designed to accommodate investors who invest in a fund up to their 
target retirement date, and plan to make gradual systematic withdrawals in &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retirement. 
In addition, investors should note that the Fund will continue to have a significant level of equity 
exposure up to, through and after its target retirement date, and this exposure could cause significant 
fluctuations in the value of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target 
allocation or other similar fund designed to maintain a relatively stable asset allocation reflecting 
the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign 
securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities 
less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage

perceived (whether by market participants, rating agencies, pricing services or otherwise) as not able 
or willing, to meet interest or principal payments when the payments become due. Actual or perceived 
changes in economic, social, public health, financial or political conditions in general or that affect 
a particular type of investment, issuer, guarantor or counterparty can reduce the ability of the party 
to meet its obligations, which can affect the credit quality, liquidity and/or value of an investment;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;credit

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;requirements, which would affect a Fund&#x2019;s ability to evaluate potential 
portfolio companies. As a result, there could be less information available about issuers in emerging 
market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate local 
companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets of emerging 
market countries may be very small, share prices of financial instruments in emerging market countries 
may be volatile and difficult to determine. Financial instruments of&#160;issuers in these countries 
may have lower overall liquidity than those of issuers in more developed countries and may be more vulnerable 
to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety 
of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors 
in emerging markets may be more limited, and U.S. authorities may have less ability to enforce certain 
regulatory or legal obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index that represents the market sectors 
in which the Fund invests across the equity and fixed-income asset classes. For periods prior to August 
1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax 
performance is shown only for the Retirement Class shares, and after-tax returns for the other classes 
of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees 
and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. 
Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will 
perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. 
The returns for the indices reflect no deduction for fees, expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;who 
retired in, or planned to retire within a few years of, 2020 and may have begun taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
39.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 56.00% of its 
assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative. The Fund had target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2020 and will reach the Fund&#x2019;s 
final target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 
2050. Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 25.35%; International 
Equity: 13.65%; Fixed-Income: 33.81%; Non-USD Fixed-Income: 5.39%; Short-Term Fixed-Income: 8.40%; Inflation-Protected 
Assets: 8.40%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors

significant level of equity exposure up to, through and after its target retirement date, and this exposure 
could cause significant fluctuations in the value of the Fund depending on the performance of the equity 
markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board 
of Trustees may authorize the merger of the Fund into another Lifecycle Fund which has also reached its 
final target allocation or other similar fund designed to maintain a relatively stable asset allocation 
reflecting the resting point on the glidepath described in the chart above. Fund shareholders will receive 
prior notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

and can result in greater price volatility and perform differently from financial instruments of U.S. 
issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also 
have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 
Fund invests a significant portion of its assets in the securities of companies in a single country or 
region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;available about issuers in emerging market countries, which could negatively affect 
Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact on a Fund&#x2019;s 
performance. Because the financial markets of emerging market countries may be very small, share prices 
of financial instruments in emerging market countries may be volatile and difficult to determine. Financial 
instruments of&#160;issuers in these countries may have lower overall liquidity than those of issuers 
in more developed countries and may be more vulnerable to market manipulation. In addition, foreign investors 
such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging 
market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full 
calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index that represents the market sectors 
in which the Fund invests across the equity and fixed-income asset classes. For periods prior to August 
1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax 
performance is shown only for the Retirement Class shares, and after-tax returns for the other classes 
of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retiring 
in, or planning to retire within a few years of, 2025 and who may begin taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
44.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 51.00% of its 
assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2025 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2055. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 28.60%; International 
Equity: 15.40%; Fixed-Income: 32.95%; Non-USD Fixed-Income: 5.25%; Short-Term Fixed-Income: 6.40%; Inflation-Protected 
Assets: 6.40%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors

significant level of equity exposure up to, through and after its target retirement date, and this exposure 
could cause significant fluctuations in the value of the Fund depending on the performance of the equity 
markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board 
of Trustees may authorize the merger of the Fund into another Lifecycle Fund which has also reached its 
final target allocation or other similar fund designed to maintain a relatively stable asset allocation 
reflecting the resting point on the glidepath described in the chart above. Fund shareholders will receive 
prior notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

and can result in greater price volatility and perform differently from financial instruments of U.S. 
issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also 
have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 
Fund invests a significant portion of its assets in the securities of companies in a single country or 
region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;available about issuers in emerging market countries, which could negatively affect 
Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact on a Fund&#x2019;s 
performance. Because the financial markets of emerging market countries may be very small, share prices 
of financial instruments in emerging market countries may be volatile and difficult to determine. Financial 
instruments of&#160;issuers in these countries may have lower overall liquidity than those of issuers 
in more developed countries and may be more vulnerable to market manipulation. In addition, foreign investors 
such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging 
market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full 
calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index that represents the market sectors 
in which the Fund invests across the equity and fixed-income asset classes. For periods prior to August 
1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax 
performance is shown only for the Retirement Class shares, and after-tax returns for the other classes 
of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retiring 
in, or planning to retire within a few years of, 2030 and who may begin taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
52.20% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 42.80% of its 
assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2030 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2060. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 33.93%; International 
Equity: 18.27%; Fixed-Income: 28.98%; Non-USD Fixed-Income: 5.02%; Short-Term Fixed-Income: 4.40%; Inflation-Protected 
Assets: 4.40%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors

significant level of equity exposure up to, through and after its target retirement date, and this exposure 
could cause significant fluctuations in the value of the Fund depending on the performance of the equity 
markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board 
of Trustees may authorize the merger of the Fund into another Lifecycle Fund which has also reached its 
final target allocation or other similar fund designed to maintain a relatively stable asset allocation 
reflecting the resting point on the glidepath described in the chart above. Fund shareholders will receive 
prior notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

and can result in greater price volatility and perform differently from financial instruments of U.S. 
issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also 
have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 
Fund invests a significant portion of its assets in the securities of companies in a single country or 
region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;available about issuers in emerging market countries, which could negatively affect 
Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact on a Fund&#x2019;s 
performance. Because the financial markets of emerging market countries may be very small, share prices 
of financial instruments in emerging market countries may be volatile and difficult to determine. Financial 
instruments of&#160;issuers in these countries may have lower overall liquidity than those of issuers 
in more developed countries and may be more vulnerable to market manipulation. In addition, foreign investors 
such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging 
market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full 
calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index that represents the market sectors 
in which the Fund invests across the equity and fixed-income asset classes. For periods prior to August 
1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax 
performance is shown only for the Retirement Class shares, and after-tax returns for the other classes 
of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retiring 
in, or planning to retire within a few years of, 2035 and who may begin taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
61.20% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 33.80% of its 
assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2035 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2065. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 39.78%; International 
Equity: 21.42%; Fixed-Income: 24.36%; Non-USD Fixed-Income: 4.64%; Short-Term Fixed-Income: 2.40%; Inflation-Protected 
Assets: 2.40%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

significant level of equity exposure up to, through and after its target retirement date, and this exposure 
could cause significant fluctuations in the value of the Fund depending on the performance of the equity 
markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board 
of Trustees may authorize the merger of the Fund into another Lifecycle Fund which has also reached its 
final target allocation or other similar fund designed to maintain a relatively stable asset allocation 
reflecting the resting point on the glidepath described in the chart above. Fund shareholders will receive 
prior notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

and can result in greater price volatility and perform differently from financial instruments of U.S. 
issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also 
have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a 
Fund invests a significant portion of its assets in the securities of companies in a single country or 
region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;available about issuers in emerging market countries, which could negatively affect 
Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact on a Fund&#x2019;s 
performance. Because the financial markets of emerging market countries may be very small, share prices 
of financial instruments in emerging market countries may be volatile and difficult to determine. Financial 
instruments of&#160;issuers in these countries may have lower overall liquidity than those of issuers 
in more developed countries and may be more vulnerable to market manipulation. In addition, foreign investors 
such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging 
market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full 
calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index that represents the market sectors 
in which the Fund invests across the equity and fixed-income asset classes. For periods prior to August 
1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax 
performance is shown only for the Retirement Class shares, and after-tax returns for the other classes 
of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retiring 
in, or planning to retire within a few years of, 2040 and who may begin taking systematic withdrawals 
upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
73.40% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 21.60% of its 
assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2040 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2070. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 47.71%; International 
Equity: 25.69%; Fixed-Income: 17.21%; Non-USD Fixed-Income: 3.59%; Short-Term Fixed-Income: 0.40%; Inflation-Protected 
Assets: 0.40%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target 
allocation or other similar fund designed to maintain a relatively stable asset allocation reflecting 
the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

Foreign investments may also have 
lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a Fund 
invests a significant portion of its assets in the securities of companies in a single country or region, 
it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign

confiscations, trade restrictions (including tariffs) and other restrictions by the United States and

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar-year 
periods covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s 
average annual total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index that represents the market 
sectors in which the Fund invests across the equity and fixed-income asset classes. For periods prior 
to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the 
Fund. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for 
the other classes of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares.

prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2045 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2075. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 54.08%; International 
Equity: 29.12%; Fixed-Income: 9.62%; Non-USD Fixed-Income: 2.18%; Short-Term Fixed-Income: 0.00%; Inflation-Protected 
Assets: 0.00%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target 
allocation or other similar fund designed to maintain a relatively stable asset allocation reflecting 
the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar-year 
periods covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s 
average annual total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index that represents the market 
sectors in which the Fund invests across the equity and fixed-income asset classes. For periods prior 
to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the 
Fund. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for 
the other classes of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares.

prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will

investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;)

their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according

assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2050 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2080. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 57.85%; International

the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging

International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield

Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation

Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target 
allocation or other similar fund designed to maintain a relatively stable asset allocation reflecting 
the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger. &lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;heightened in emerging or developing markets. Foreign investments may also have 
lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent a Fund 
invests a significant portion of its assets in the securities of companies in a single country or region, 
it may be more susceptible to adverse economic, market, political or regulatory events or conditions 
affecting that country or region. Foreign investments may also be subject to risk of loss because of 
more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger,

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;investments in such securities less liquid (or illiquid) or more difficult to

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar-year 
periods covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s 
average annual total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index that represents the market 
sectors in which the Fund invests across the equity and fixed-income asset classes. For periods prior 
to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the 
Fund. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for 
the other classes of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares.

prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;)

their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;retiring

assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2055 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2085. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 59.15%; International

the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target

the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar-year 
periods covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s 
average annual total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index that represents the market 
sectors in which the Fund invests across the equity and fixed-income asset classes. For periods prior 
to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the 
Fund. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for 
the other classes of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s 
prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees 
and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. 
Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will 
perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. 
The returns for the indices reflect no deduction for fees, expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For

investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

of funds&#x201d; that invests in Class W, Class R6 or Class I shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;)

their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according

assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2060 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2090. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 59.96%; International 
Equity: 32.29%; Fixed-Income: 2.20%; Non-USD Fixed-Income: 0.55%; Short-Term Fixed-Income: 0.00%; Inflation-Protected 
Assets: 0.00%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June&#160;30, 
2025, are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target

the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;.

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar-year 
periods covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s 
average annual total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index that represents the market 
sectors in which the Fund invests across the equity and fixed-income asset classes. For periods prior 
to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the 
Fund. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for 
the other classes of shares will vary from the after-tax returns presented for the Retirement Class&#160;shares.

prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds for certain fees

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

Class I shares of other Nuveen mutual funds and in other investment pools or investment products, including 
other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser,

Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the 
&#x201c;Underlying Funds&#x201d;). In general, the Fund is designed for investors who have an approximate 
target retirement year in mind, and the Fund&#x2019;s investments are adjusted from more aggressive to 
more conservative over time as the Fund&#x2019;s target retirement year approaches and for approximately 
30 years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed

assets to fixed-income Underlying Funds and 5.00% of its assets to direct real estate Underlying Funds. 
These allocations represent targets for equity, fixed-income and direct real estate asset classes. Target 
allocations will change over time and actual allocations may vary up to ten percentage points from the 
targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually 
become more conservative, moving to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% 
direct real estate in the Fund&#x2019;s target retirement year of 2065 and reaching the Fund&#x2019;s final 
target allocation of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2095. 
Within the equity, fixed-income and direct real estate asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, short-term fixed-income, inflation-protected assets and direct real estate) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 60.78%; International 
Equity: 32.73%; Fixed-Income: 1.20%; Non-USD Fixed-Income: 0.30%; Short-Term Fixed-Income: 0.00%; Inflation-Protected 
Assets: 0.00%; and Direct Real Estate: 5.00%. The asset class and market sector names used herein are 
intended to reflect the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen 
International Value Fund and Nuveen Quant International Small Cap Equity Fund (International Equity); 
Nuveen Core Bond Fund, Nuveen Core Plus Bond Fund, Nuveen Floating Rate Income Fund and Nuveen High Yield 
Fund (Fixed-Income); Nuveen Emerging Markets Debt Fund and Nuveen International Bond Fund (Non-USD Fixed-Income); 
Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the Fund&#x2019;s returns 
will reflect investments in a mix of domestic and foreign equities of companies of various sizes and 
market capitalizations, a variety of domestic and foreign fixed-income instruments of private and governmental 
issuers of varying maturities and credit qualities and direct real estate.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional 
or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, 
may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such 
Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels 
of risk and potential return at the particular time. The Fund&#x2019;s portfolio management team may also 
add a new market sector if it believes that will help to achieve the Fund&#x2019;s investment objective. 
The relative allocations among Underlying Funds within a market sector may be changed at any time without 
notice to shareholders, and the portfolio management team may use tactical allocation to take advantage 
of short to intermediate term opportunities through a combination of positions in Underlying Funds. If 
10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market 
sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June&#160;30, 
2025, are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity 
and International Equity market sectors, respectively, and corresponding reductions in allocations to 
other Underlying Funds in those market sectors; (ii) the addition of Nuveen Floating Rate Income Fund 
as a new Underlying Fund in the Fixed-Income market sector and corresponding reductions in allocations 
to other Underlying Funds in that market sector; (iii) the redesignation of Nuveen Emerging Markets Debt 
Fund and Nuveen International Bond Fund from the Fixed-Income market sector to the new Non-USD Fixed-Income 
market sector; and (iv) strategic reallocations among certain Underlying Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After the Fund reaches its final target allocation, the Board of Trustees may 
authorize the merger of the Fund into another Lifecycle Fund which has also reached its final target

the resting point on the glidepath described in the chart above. Fund shareholders will receive prior 
notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

more or less foreign government regulation, less public information, less stringent investor protections 
and less stringent accounting, corporate governance, financial reporting and disclosure standards. Changes 
in the value of foreign currencies may make the return on an investment increase or decrease, unrelated 
to the quality or performance of the investment itself. The imposition of sanctions, exchange controls 
(including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other 
restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s investments. 
Economic sanctions and other similar governmental actions or developments could, among other things, 
effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign securities 
or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities less 
liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small-

price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a Fund&#x2019;s investment 
adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization companies often experience 
greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, 
more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact

are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;.

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year since inception of the Retirement Class. Because the 
expenses vary across share classes, the performance of the Retirement Class may vary from the other share 
classes. Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter 
during &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;the 
full calendar-year periods covered by the bar chart. The performance table following the bar chart shows 
the Fund&#x2019;s average annual total returns for the Retirement, Class I, Premier and Class R6 classes 
over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2024, 
and how those returns compare to those of a broad-based securities market index and a composite index 
that represents the market sectors in which the Fund invests across the equity and fixed-income asset 
classes. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged,

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee

Class I shares of other Nuveen mutual funds and in other investment pools or investment products, including 
other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, 
Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen 
Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the 
&#x201c;Underlying Funds&#x201d;). In general, the Fund is designed for investors who have an approximate 
target retirement year in mind, and the Fund&#x2019;s investments are adjusted from more aggressive to 
more conservative over time as the Fund&#x2019;s target retirement year approaches and for approximately 
30 years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed 
for investors retiring in, or planning to retire within a few years of, 2070 and who may begin taking 
systematic withdrawals upon retirement. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 94.75% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of 
the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 0.25% of its assets to fixed-income Underlying 
Funds and 5.00% of its assets to direct real estate Underlying Funds. These allocations represent targets 
for equity, fixed-income and direct real estate asset classes. Target allocations will change over time 
and actual allocations may vary up to ten percentage points from the targets. The target allocations 
along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving 
to target allocations of approximately 45.00% equity/50.00% fixed-income/5.00% direct real estate in 
the Fund&#x2019;s target retirement year of 2070 and reaching the Fund&#x2019;s final target allocation 
of approximately 20.00% equity/80.00% fixed-income/0.00% direct real estate in 2100. Within the equity, 
fixed-income and direct real estate asset classes, Nuveen Asset Management allocates the Fund&#x2019;s 
investments to particular market sectors (U.S. equity, international equity, fixed-income, non-USD fixed-income, 
short-term fixed-income, inflation-protected assets and direct real estate) represented by various Underlying 
Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s target market sector 
allocations. The Fund&#x2019;s current target market sector allocations for June 30, 2026, which will 
change over time, are approximately as follows: U.S. Equity: 61.59%; International Equity: 33.16%; Fixed-Income: 
0.20%; Non-USD Fixed-Income: 0.05%; Short-Term Fixed-Income: 0.00%; Inflation-Protected Assets: 0.00%; 
and Direct Real Estate: 5.00%. The asset class and market sector names used herein are intended to reflect 
the primary type of investment of the Underlying Funds within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying Funds may include 
the Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen Large Cap Value Fund, Nuveen Quant 
Small Cap Equity Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Dividend Growth Fund, Nuveen Dividend 
Value Fund, Nuveen Growth Opportunities ETF and Nuveen Small Cap Select Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Fund, Nuveen International Equity Fund, Nuveen International Opportunities Fund, Nuveen

Nuveen Money Market Fund and Nuveen Short Term Bond Fund (Short-Term Fixed-Income); Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets); and Nuveen Real Property Fund LP (Direct Real Estate). 
Nuveen Real Property Fund LP is a private fund, which is not available for investment by the general 
public; it is currently offered exclusively to investment pools or investment products managed by Nuveen 
Asset Management or its affiliates.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the

in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds within 
a market sector may be changed at any time without notice to shareholders, and the portfolio management 
team may use tactical allocation to take advantage of short to intermediate term opportunities through 
a combination of positions in Underlying Funds. If 10%&#160;or more of the Fund&#x2019;s assets are expected 
to be invested in any Underlying Fund or market sector not listed above, shareholders will receive prior 
notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to 
invest in other investment pools or investment products noted above, the Fund may invest in ETFs and 
exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities in 
order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash management, 
hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with the types of 
securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, 
will also be subject to the general risks of fixed-income securities, including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After

described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly 
or unpredictably due to a variety of factors, including responses to government actions or interventions, 
or changing economic, political or market conditions. Market risk may affect a single issuer, industry 
or sector of the economy, or it &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;may affect the market as a whole. Such conditions may add

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;trade restrictions (including tariffs) and other restrictions by the United States 
or other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to&#160;predict;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The

rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments 
as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make 
timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s ability to enforce 
its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments 
in U.S. issuers. To the extent a Fund invests a significant portion of its assets in the securities of 
companies in a single country or region, it may be more susceptible to adverse economic, market, political 
or regulatory events or conditions affecting that country or region. Foreign investments may also be 
subject to risk of loss because of more or less foreign government regulation, less public information, 
less stringent investor protections and less stringent accounting, corporate governance, financial reporting 
and disclosure standards. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. The imposition 
of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions 
(including tariffs) and other restrictions by the United States and other governments may also negatively 
impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to 
predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject

remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in

Nuveen mutual funds and in other investment pools or investment products, including other funds or exchange-traded 
funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC 
(&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen 
Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). The 
Fund invests in Underlying Funds according to a relatively stable asset allocation strategy that will 
not gradually adjust over time and is designed for investors who are already in retirement (i.e., have 
already passed their retirement year) and may have begun taking systematic withdrawals upon retirement. 
The Fund has a policy of investing at least 80% of its assets in Underlying Funds that are managed to 
seek investment returns that track particular market indices. For purposes of the 80% investment policy, 
the term &#x201c;assets&#x201d; means net assets, plus the amount of any borrowings for investment purposes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 40.00% of 
the Fund&#x2019;s assets to equity Underlying Funds and 60.00% of its assets to fixed-income Underlying 
Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations 
may be changed and actual allocations may vary up to ten percentage points from the targets. Within the 
equity and fixed-income asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments 
to particular market sectors (U.S. equity, international equity, fixed-income, non-USD fixed-income, 
high yield bond, short-term fixed-income and inflation-protected assets) represented by various Underlying 
Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s target market sector 
allocations. The Fund&#x2019;s current target market sector allocations for June&#160;30, 2026, which 
may change, are approximately as follows: U.S. Equity: &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;26.00%; 
International Equity: 14.00%; Fixed-Income: 27.61%; Non-USD Fixed-Income: 6.90%; High Yield Bond: 5.49%; 
Short-Term Fixed-Income: 10.00%; and Inflation-Protected Assets: 10.00%. The asset class and market sector 
names used herein are intended to reflect the primary type of investment of the Underlying Funds within 
each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying 
Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging Markets Equity Index Fund 
and Nuveen International Equity Index Fund (International Equity); Nuveen Bond Index Fund (Fixed-Income); 
Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High Yield Corporate Bond ETF 
(High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income) and Nuveen Inflation Linked 
Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the 
Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future allocations if Nuveen Asset 
Management believes that such Underlying Funds and/or market sectors are appropriate in light of the 
Fund&#x2019;s desired levels of risk and potential return at the particular time. The Fund&#x2019;s portfolio 
management team may also add a new market sector if it believes that will help to achieve the Fund&#x2019;s 
investment objective. The relative allocations among Underlying Funds within a market sector may be changed 
at any time without notice to shareholders. If 10% or more of the Fund&#x2019;s assets are expected to 
be invested in any Underlying Fund or market sector not listed above, shareholders will receive prior 
notice of such change. Investors should note that the Fund has a significant level of equity exposure 
and this exposure could cause fluctuation in the value of the Fund depending on the performance of the 
equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment 
pools or investment products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) 
to gain exposure to various market sectors or securities in order to effect its asset allocation strategy. 
Additionally, the Fund may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs 
or ETNs will be subject to the risks associated with the types of securities or sectors that they track, 
while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks 
of fixed-income securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s 
asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations 
within each market sector, as of June 30, 2025, are listed in the chart below. The Fund has relatively 
fixed asset allocations that will not gradually adjust over time. Underlying Fund allocations may change 
from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management expects that

and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements 
the addition of Nuveen International Aggregate Bond ETF and Nuveen High Yield Corporate Bond ETF as new 
Underlying Funds in the new Non-USD Fixed Income and High Yield Bond market sectors, respectively, and

volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, 
market or economic developments as well as armed conflicts and can result in greater price volatility 
and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging 
or developing markets. Foreign investments may also have lower liquidity and be more difficult to value 
than investments in U.S. issuers. To the extent a Fund invests a significant portion of its assets in 
the securities of companies in a single country or region, it may be more susceptible to adverse economic, 
market, political or regulatory events or conditions affecting that country or region. Foreign investments 
may also be subject to risk of loss because of more or less foreign government regulation, less public 
information, less stringent investor protections and less stringent accounting, corporate governance, 
financial reporting and disclosure standards. Changes in the value of foreign currencies may make the 
return on an investment increase or decrease, unrelated to the quality or performance of the investment 
itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, 
trade restrictions (including tariffs) and other restrictions by the United States or other governments 
may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental 
actions or developments could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability 
to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make 
a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more difficult to value. The 
type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and 
their impact is impossible to predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of

resources, products and markets. Securities of small-cap companies often have lower overall liquidity 
than securities of larger companies as a result of there being a smaller market for their securities, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization 
companies often experience greater price volatility, lower trading volume and lower overall liquidity 
than the stocks of larger, more established companies.&lt;/p&gt;</oef:RiskTextBlock>

risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, including rates that fall below zero, or a lack of market participants 
may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making 
it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values 
of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income 
securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile 
but may provide lower returns than fixed-income securities with longer durations or maturities. Other 
factors that may affect the value of debt securities include, but are not limited to, economic, political, 
public health, and other crises and responses by governments and companies to such crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;decrease, unrelated to the quality or performance of the investment itself. The 
imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade 
restrictions (including tariffs) and other restrictions by the United States and other governments may 
also negatively impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental 
actions or developments could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability 
to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make 
a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more difficult to value. The 
type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and 
their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The risk that, during periods of falling interest

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions

and U.S. authorities may have less ability to enforce certain regulatory or legal obligations or otherwise 
bring actions against bad actors in emerging market countries.&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;composite

LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for the Retirement Class shares, and after-tax returns for the other classes of shares will vary 
from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The 
returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s prior investment adviser, 
to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these 
waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund 
(before and after taxes) is not necessarily an indication of how it will perform in the future. The indices

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors who retired in, or planned to retire within a 
few years of, 2010 and who may have begun taking systematic withdrawals upon retirement. The Fund has 
a policy of investing at least 80% of &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;its 
assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that 
are managed to seek investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen 
Asset Management currently expects to allocate approximately 34.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s 
assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 66.00% of its assets to fixed-income Underlying Funds. 
These allocations represent targets for equity and fixed-income asset classes. Target allocations will 
change over time and actual allocations may vary up to ten percentage points from the targets. The target 
allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative. 
The Fund had target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s 
target retirement year of 2010 and will reach the Fund&#x2019;s final target allocation of approximately 
20.00% equity/80.00% fixed-income in 2040. Within the equity and fixed-income asset classes, Nuveen Asset 
Management allocates the Fund&#x2019;s investments to particular market sectors (U.S. equity, international 
equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected 
assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% 
from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current target market sector 
allocations for June 30, 2026, which will change over time, are approximately as follows: U.S. Equity: 
22.10%; International Equity: 11.90%; Fixed-Income: 27.61%; Non-USD Fixed-Income: 6.90%; High Yield Bond: 
5.49%; Short-Term Fixed-Income: 16.00%; and Inflation-Protected Assets: 10.00%. The asset class and market 
sector names used herein are intended to reflect the primary type of investment of the Underlying Funds 
within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector 
allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); Nuveen Bond 
Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High 
Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); 
and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors who retired in, or planned to retire within a 
few years of, 2015 and who may have begun taking systematic withdrawals upon retirement. The Fund has 
a policy of investing at least 80% of &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;its 
assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that 
are managed to seek investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen 
Asset Management currently expects to allocate approximately 39.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s 
assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 61.00% of its assets to fixed-income Underlying Funds. 
These allocations represent targets for equity and fixed-income asset classes. Target allocations will 
change over time and actual allocations may vary up to ten percentage points from the targets. The target 
allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative. 
The Fund had target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s 
target retirement year of 2015 and will reach the Fund&#x2019;s final target allocation of approximately 
20.00% equity/80.00% fixed-income in 2045. Within the equity and fixed-income asset classes, Nuveen Asset 
Management allocates the Fund&#x2019;s investments to particular market sectors (U.S. equity, international 
equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected 
assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% 
from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current target market sector 
allocations for June 30, 2026, which will change over time, are approximately as follows: U.S. Equity: 
25.35%; International Equity: 13.65%; Fixed-Income: 27.61%; Non-USD Fixed-Income: 6.90%; High Yield Bond: 
5.49%; Short-Term Fixed-Income: 11.00%; and Inflation-Protected Assets: 10.00%. The asset class and market 
sector names used herein are intended to reflect the primary type of investment of the Underlying Funds 
within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector 
allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); Nuveen Bond 
Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High 
Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); 
and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors who retired in, or planned to retire within a 
few years of, 2020 and who may have begun taking systematic withdrawals upon retirement. The Fund has 
a policy of investing at least 80% of &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;its 
assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that 
are managed to seek investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen 
Asset Management currently expects to allocate approximately 44.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s 
assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 56.00% of its assets to fixed-income Underlying Funds. 
These allocations represent targets for equity and fixed-income asset classes. Target allocations will 
change over time and actual allocations may vary up to ten percentage points from the targets. The target 
allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative. 
The Fund had target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s 
target retirement year of 2020 and will reach the Fund&#x2019;s final target allocation of approximately 
20.00% equity/80.00% fixed-income in 2050. Within the equity and fixed-income asset classes, Nuveen Asset 
Management allocates the Fund&#x2019;s investments to particular market sectors (U.S. equity, international 
equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected 
assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% 
from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current target market sector 
allocations for June 30, 2026, which will change over time, are approximately as follows: U.S. Equity: 
28.60%; International Equity: 15.40%; Fixed-Income: 27.47%; Non-USD Fixed-Income: 6.87%; High Yield Bond: 
4.86%; Short-Term Fixed-Income: 8.40%; and Inflation-Protected Assets: 8.40%. The asset class and market 
sector names used herein are intended to reflect the primary type of investment of the Underlying Funds 
within each of these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector 
allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging 
Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); Nuveen Bond 
Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High 
Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); 
and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2025 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;assets, 
plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek 
investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management 
currently expects to allocate approximately 49.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying 
Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 51.00% of its assets to fixed-income Underlying Funds. These allocations 
represent targets for equity and fixed-income asset classes. Target allocations will change over time 
and actual allocations may vary up to ten percentage points from the targets. The target allocations 
along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving 
to target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s target retirement 
year of 2025 and reaching the Fund&#x2019;s final target allocation of approximately 20.00% equity/80.00% 
fixed-income in 2055. Within the equity and fixed-income asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected assets) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 31.85%; International 
Equity: 17.15%; Fixed-Income: 27.30%; Non-USD Fixed-Income: 6.82%; High Yield Bond: 4.08%; Short-Term 
Fixed-Income: 6.40%; and Inflation-Protected Assets: 6.40%. The asset class and market sector names used 
herein are intended to reflect the primary type of investment of the Underlying Funds within each of 
these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying 
Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging Markets Equity Index Fund 
and Nuveen International Equity Index Fund (International Equity); Nuveen Bond Index Fund (Fixed-Income); 
Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High Yield Corporate Bond ETF 
(High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); and Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2030 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;assets, 
plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek 
investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management 
currently expects to allocate approximately 56.40% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying 
Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 43.60% of its assets to fixed-income Underlying Funds. These allocations 
represent targets for equity and fixed-income asset classes. Target allocations will change over time 
and actual allocations may vary up to ten percentage points from the targets. The target allocations 
along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving 
to target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s target retirement 
year of 2030 and reaching the Fund&#x2019;s final target allocation of approximately 20.00% equity/80.00% 
fixed-income in 2060. Within the equity and fixed-income asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected assets) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 36.66%; International 
Equity: 19.74%; Fixed-Income: 25.20%; Non-USD Fixed-Income: 6.30%; High Yield Bond: 3.29%; Short-Term 
Fixed-Income: 4.40%; and Inflation-Protected Assets: 4.40%. The asset class and market sector names used 
herein are intended to reflect the primary type of investment of the Underlying Funds within each of 
these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying 
Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging Markets Equity Index Fund 
and Nuveen International Equity Index Fund (International Equity); Nuveen Bond Index Fund (Fixed-Income); 
Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High Yield Corporate Bond ETF 
(High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); and Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2035 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;assets, 
plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek 
investment returns that track particular market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management 
currently expects to allocate approximately 64.40% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying 
Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 35.60% of its assets to fixed-income Underlying Funds. These allocations 
represent targets for equity and fixed-income asset classes. Target allocations will change over time 
and actual allocations may vary up to ten percentage points from the targets. The target allocations 
along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving 
to target allocations of approximately 50.00% equity/50.00% fixed-income in the Fund&#x2019;s target retirement 
year of 2035 and reaching the Fund&#x2019;s final target allocation of approximately 20.00% equity/80.00% 
fixed-income in 2065. Within the equity and fixed-income asset classes, Nuveen Asset Management allocates 
the Fund&#x2019;s investments to particular market sectors (U.S. equity, international equity, fixed-income, 
non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected assets) represented 
by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund&#x2019;s 
target market sector allocations. The Fund&#x2019;s current target market sector allocations for June 
30, 2026, which will change over time, are approximately as follows: U.S. Equity: 41.86%; International 
Equity: 22.54%; Fixed-Income: 22.63%; Non-USD Fixed-Income: 5.66%; High Yield Bond: 2.51%; Short-Term 
Fixed-Income: 2.40%; and Inflation-Protected Assets: 2.40%. The asset class and market sector names used 
herein are intended to reflect the primary type of investment of the Underlying Funds within each of 
these categories.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target market sector allocations to Underlying 
Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging Markets Equity Index Fund 
and Nuveen International Equity Index Fund (International Equity); Nuveen Bond Index Fund (Fixed-Income); 
Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High Yield Corporate Bond ETF 
(High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income); and Nuveen Inflation 
Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds for each market sector, as well as 
additional or replacement market sectors, may be included when making future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if 
Nuveen Asset Management believes that such Underlying Funds and/or market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate 
in light of the Fund&#x2019;s desired levels of risk and potential return at the particular time. The 
Fund&#x2019;s portfolio management team may also add a new market sector if it believes that will help 
to achieve the Fund&#x2019;s investment objective. The relative allocations among Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;within 
a market sector may be changed at any time without notice to shareholders. If 10%&#160;or more of the 
Fund&#x2019;s assets are expected to be invested in any Underlying Fund or market sector not listed above, 
shareholders will receive prior notice of such change.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various market sectors or securities 
in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash 
management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with 
the types of securities or sectors that they track, while ETNs, which are structured as fixed-income 
obligations, will also be subject to the general risks of fixed-income securities, including credit risk. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations within each 
asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed 
in the chart below. These allocations will change over&#160;time. Underlying Fund allocations in particular 
may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, Nuveen Asset Management 
expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted 
over time as Nuveen Asset Management implements the addition of Nuveen International Aggregate Bond ETF 
and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and 
High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen 
Bond Index Fund.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom;

allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile 
and difficult to determine. Financial instruments of&#160;issuers in these countries may have lower overall 
liquidity than those of issuers in more developed countries and may be more vulnerable to market manipulation. 
In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions 
in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets 
may be more limited, and U.S. authorities may have less ability to enforce certain regulatory or legal 
obligations or otherwise bring actions against bad actors in emerging market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Fund is a &#x201c;fund of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2040 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
75.60% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 24.40% of 
its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2040 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2070. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 49.14%; International Equity: 26.46%; Fixed-Income: 17.50%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
4.37%; High Yield Bond: 1.73%; Short-Term Fixed-Income: 0.40%; and Inflation-Protected Assets: 0.40%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term 
Fixed-Income); and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds 
for each market sector, as well as additional or replacement market sectors, may be included when making 
future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements the addition of Nuveen International 
Aggregate Bond ETF and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt;Non-USD

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments 
as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make 
timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s ability to enforce 
its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments 
in U.S. issuers. To the extent a Fund invests a significant portion of its assets in the securities of 
companies in a single country or region, it may be more susceptible to adverse economic, market, political 
or regulatory events or conditions affecting that country or region. Foreign investments may also be 
subject to risk of loss because of more or less foreign government regulation, less public information, 
less stringent investor protections and less stringent accounting, corporate governance, financial reporting 
and disclosure standards. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. The imposition 
of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions 
(including tariffs) and other restrictions by the United States and other governments may also negatively 
impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to 
predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Fund is a &#x201c;fund of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2045 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
84.40% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 15.60% of 
its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2045 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2075. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 54.86%; International Equity: 29.54%; Fixed-Income: 11.73%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
2.93%; High Yield Bond: 0.94%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term 
Fixed-Income); and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds

future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus,

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension risk&#x2014;The risk that, during periods of rising

payments become due. Actual or perceived changes in economic, social, public health, financial or political 
conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments

its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject 
to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal 
remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability 
to enforce certain regulatory or legal obligations or otherwise bring actions against bad actors in emerging 
market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, 
expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For current performance information of each share class, including

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Fund is a &#x201c;fund of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2050 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
89.20% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 10.80% of 
its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2050 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2080. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 57.98%; International Equity: 31.22%; Fixed-Income: 8.51%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
2.13%; High Yield Bond: 0.16%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term 
Fixed-Income); and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds 
for each market sector, as well as additional or replacement market sectors, may be included when making 
future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, 
are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements the addition of Nuveen International 
Aggregate Bond ETF and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt;Non-USD 
Fixed Income and High Yield Bond market sectors, respectively, and a corresponding reduction in allocation

to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value

described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments 
as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make 
timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s ability to enforce 
its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments 
in U.S. issuers. To the extent a Fund invests a significant portion of its assets in the securities of 
companies in a single country or region, it may be more susceptible to adverse economic, market, political 
or regulatory events or conditions affecting that country or region. Foreign investments may also be 
subject to risk of loss because of more or less foreign government regulation, less public information, 
less stringent investor protections and less stringent accounting, corporate governance, financial reporting 
and disclosure standards. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. The imposition 
of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions 
(including tariffs) and other restrictions by the United States and other governments may also negatively 
impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to 
predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged,

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee

Fund is a &#x201c;fund of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2055 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
91.00% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 9.00% of its 
assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2055 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2085. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 59.15%; International Equity: 31.85%; Fixed-Income: 7.20%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
1.80%; High Yield Bond: 0.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term

a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds

future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025,

in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus,

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more

small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates

payments become due. Actual or perceived changes in economic, social, public health, financial or political 
conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject 
to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal 
remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability 
to enforce certain regulatory or legal obligations or otherwise bring actions against bad actors in emerging 
market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each 
full calendar year for the last ten years. Because the expenses vary across share classes, the performance 
of the Retirement Class may vary from the other share classes. Below the bar chart are the best and worst 
returns of the Retirement Class for a calendar quarter during the full calendar-year periods covered 
by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average annual 
total returns for the Retirement, Class I, Premier and Class R6 classes over the applicable one-year, 
five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare 
to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s target 
allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) served 
as investment adviser to the Fund. After-tax performance is shown only for the Retirement Class shares, 
and after-tax returns for the other classes of shares will vary from the after-tax returns presented 
for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, 
expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For current performance information of each share class, including

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Fund is a &#x201c;fund of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and 
in other investment pools or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) 
advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2060 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
92.25% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 7.75% of its 
assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50.00% equity/50.00% 
fixed-income in the Fund&#x2019;s target retirement year of 2060 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2090. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 59.96%; International Equity: 32.29%; Fixed-Income: 6.20%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
1.55%; High Yield Bond: 0.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term 
Fixed-Income); and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds 
for each market sector, as well as additional or replacement market sectors, may be included when making 
future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June&#160;30, 
2025, are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus, 
Nuveen Asset Management expects that the allocations among the market sectors and Underlying Funds set 
forth below will be adjusted over time as Nuveen Asset Management implements the addition of Nuveen International 
Aggregate Bond ETF and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt;Non-USD

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments 
as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make 
timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s ability to enforce 
its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments 
in U.S. issuers. To the extent a Fund invests a significant portion of its assets in the securities of 
companies in a single country or region, it may be more susceptible to adverse economic, market, political 
or regulatory events or conditions affecting that country or region. Foreign investments may also be 
subject to risk of loss because of more or less foreign government regulation, less public information, 
less stringent investor protections and less stringent accounting, corporate governance, financial reporting 
and disclosure standards. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. The imposition 
of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions 
(including tariffs) and other restrictions by the United States and other governments may also negatively 
impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to 
predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject

the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary 
across share classes, the performance of the Retirement Class may vary from the other share classes. 
Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter during 
the full calendar-year periods covered by the bar chart. The performance table following the bar chart 
shows the Fund&#x2019;s average annual total returns for the Retirement, Class I, Premier and Class R6 
classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index based on the Fund&#x2019;s target allocations. For periods prior to August 1, 2026, Teachers Advisors, 
LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for the Retirement Class shares, and after-tax returns for the other classes of shares will vary 
from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The

example is intended to help you compare the cost of investing in shares of the Fund with the cost of 
investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time 
periods indicated and then redeem all your shares at the end of those periods. The example also assumes 
that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee 
waiver and/or expense reimbursement arrangements will each remain in place for the durations noted in 
the table above. Although your actual costs may be higher or lower, based on these assumptions your costs 
would be: &lt;/span&gt;&lt;/p&gt;</oef:ExpenseExampleNarrativeTextBlock>

Nuveen mutual funds and in other investment pools or investment products, including other funds or exchange-traded 
funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC 
(&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen 
Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In 
general, the Fund is designed for investors who have an approximate target retirement year in mind, and 
the Fund&#x2019;s investments are adjusted from more aggressive to more conservative over time as the 
Fund&#x2019;s target retirement year approaches and for approximately 30 years afterwards. The Fund invests 
in Underlying Funds according to an asset allocation strategy designed for investors retiring in, or 
planning to retire within a few years of, 2065 and who may begin taking systematic withdrawals upon retirement. 
The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings 
for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular 
market indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
93.50% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 6.50% of its 
assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% 
fixed-income in the Fund&#x2019;s target retirement year of 2065 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2095. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 60.78%; International Equity: 32.73%; Fixed-Income: 5.20%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
1.30%; High Yield Bond: 0.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term 
Fixed-Income); and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds 
for each market sector, as well as additional or replacement market sectors, may be included when making 
future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, market sector allocations 
within each asset class, and Underlying Fund allocations within each market sector, as of June&#160;30, 
2025, are listed in the chart below. These allocations will change over&#160;time. Underlying Fund allocations 
in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the date of this Prospectus,

to gradually move the Fund&#x2019;s target allocations over time between the different target market sector 
allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks 
to achieve its final target market sector allocations approximately 30 years following the target&#160;date.

target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors 
should note that the Fund will continue to have a significant level of equity exposure up to, through 
and after its target retirement date, and this exposure could cause significant fluctuations in the value 
of the Fund depending on the performance of the equity markets generally.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;After 
the Fund reaches its final target allocation, the Board of Trustees may authorize the merger of the Fund 
into another Lifecycle Index Fund which has also reached its final target allocation or other similar 
fund designed to maintain a relatively stable asset allocation reflecting the resting point on the glidepath 
described in the chart above. Fund shareholders will receive prior notice of any such merger.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more

broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage 
loans sooner than expected, forcing a Fund to reinvest the unanticipated proceeds at lower interest rates 
and resulting in a decline in income;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;extension risk&#x2014;The risk that, during periods of rising

payments become due. Actual or perceived changes in economic, social, public health, financial or political 
conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject 
to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal 
remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability 
to enforce certain regulatory or legal obligations or otherwise bring actions against bad actors in emerging 
market countries.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of the Retirement Class of 
the Fund, before taxes, in each full calendar year since inception of the Retirement Class. Because the 
expenses vary across share classes, the performance of the Retirement Class may vary from the other share 
classes. Below the bar chart are the best and worst returns of the Retirement Class for a calendar quarter 
during the full calendar-year periods covered by the bar chart. The performance table following the bar 
chart shows the Fund&#x2019;s average annual total returns for the Retirement, Class I, Premier and Class 
R6 classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index based on the Fund&#x2019;s target allocations. For periods prior to August 1, 2026, Teachers Advisors, 
LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for the Retirement Class shares, and after-tax returns for the other classes of shares will vary 
from the after-tax returns presented for the Retirement Class&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The 
returns shown below reflect previous agreements by Advisors, the Fund&#x2019;s prior investment adviser, 
to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these 
waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund 
(before and after taxes) is not necessarily an indication of how it will perform in the future. The indices

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee

of funds&#x201d; that invests in Class W shares of other Nuveen mutual funds and in other investment pools 
or investment products, including other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by 
the Fund&#x2019;s investment adviser, Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), 
the Fund&#x2019;s sub-adviser, Nuveen Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or 
their affiliates (collectively, the &#x201c;Underlying Funds&#x201d;). In general, the Fund is designed 
for investors who have an approximate target retirement year in mind, and the Fund&#x2019;s investments 
are adjusted from more aggressive to more conservative over time as the Fund&#x2019;s target retirement 
year approaches and for approximately 30 years afterwards. The Fund invests in Underlying Funds according 
to an asset allocation strategy designed for investors retiring in, or planning to retire within a few 
years of, 2070 and who may begin taking systematic withdrawals upon retirement. The Fund has a policy 
of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment 
purposes) in Underlying Funds that are managed to seek investment returns that track particular market 
indices. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Nuveen Asset Management currently expects to allocate approximately 
94.75% &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;of the Fund&#x2019;s assets to equity Underlying Funds&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; and 5.25% of its 
assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income 
asset classes. Target allocations will change over time and actual allocations may vary up to ten percentage 
points from the targets. The target allocations along the investment glidepath, illustrated in the chart 
below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% 
fixed-income in the Fund&#x2019;s target retirement year of 2070 and reaching the Fund&#x2019;s final target 
allocation of approximately 20.00% equity/80.00% fixed-income in 2100. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income 
and inflation-protected assets) represented by various Underlying Funds. These market sector allocations 
may vary by up to 10% from the Fund&#x2019;s target market sector allocations. The Fund&#x2019;s current 
target market sector allocations for June 30, 2026, which will change over time, are approximately as 
follows: U.S. Equity: 61.59%; International Equity: 33.16%; Fixed-Income: 4.20%; Non-USD Fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Income: 
1.05%; High Yield Bond: 0.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%. 
The asset class and market sector names used herein are intended to reflect the primary type of investment 
of the Underlying Funds within each of these categories.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s target 
market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); 
Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); 
Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); 
Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term

a result of its investments in the Underlying Funds, the Fund&#x2019;s returns will reflect investments 
in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and 
a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying 
maturities and credit qualities.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Additional or replacement Underlying Funds

future &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;allocations if Nuveen Asset Management believes that such Underlying Funds and/or 
market sectors&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; are appropriate in light of the Fund&#x2019;s desired levels of risk and potential 
return at the particular time. The Fund&#x2019;s portfolio management team may also add a new market sector 
if it believes that will help to achieve the Fund&#x2019;s investment objective. The relative allocations 
among Underlying Funds within a market sector may be changed at any time without notice to shareholders. 
If 10%&#160;or more of the Fund&#x2019;s assets are expected to be invested in any Underlying Fund or 
market sector not listed above, shareholders will receive prior notice of such change.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As 
part of the Fund&#x2019;s ability to invest in other investment pools or investment products noted above, 
the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain exposure to various 
market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund 
may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject 
to the risks associated with the types of securities or sectors that they track, while ETNs, which are 
structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, 
including credit risk. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s current target asset class allocations, market 
sector allocations within each asset class, and Underlying Fund allocations within each market sector,

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;political or regulatory events or conditions affecting that country or region. 
Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States or 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price volatility, lower trading volume 
and lower overall liquidity than the stocks of larger, more established companies.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;may lead to decreased liquidity and increased volatility in the fixed-income or 
debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates 
change, the values of longer duration fixed-income securities usually change more than the values of 
shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations 
or maturities will be less volatile but may provide lower returns than fixed-income securities with longer 
durations or maturities. Other factors that may affect the value of debt securities include, but are 
not limited to, economic, political, public health, and other crises and responses by governments and 
companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign issuers 
involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments 
as well as armed conflicts. These developments may impact the ability of a foreign debt issuer to make 
timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s ability to enforce 
its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. 
Foreign investments may also have lower overall liquidity and be more difficult to value than investments 
in U.S. issuers. To the extent a Fund invests a significant portion of its assets in the securities of 
companies in a single country or region, it may be more susceptible to adverse economic, market, political 
or regulatory events or conditions affecting that country or region. Foreign investments may also be 
subject to risk of loss because of more or less foreign government regulation, less public information, 
less stringent investor protections and less stringent accounting, corporate governance, financial reporting 
and disclosure standards. Changes in the value of foreign currencies may make the return on an investment 
increase or decrease, unrelated to the quality or performance of the investment itself. The imposition 
of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions 
(including tariffs) and other restrictions by the United States and other governments may also negatively 
impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to 
predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, share prices of financial instruments in emerging market 
countries may be volatile and difficult to determine. Financial instruments of&#160;issuers in these 
countries may have lower overall liquidity than those of issuers in more developed countries and may 
be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject

remedies for investors in emerging markets may be more limited, and U.S. authorities may have less ability

shares of other Nuveen mutual funds and in other investment pools or investment products, including other 
funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen 
Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, 
LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying 
Funds&#x201d;). The Fund is designed for investors seeking current income with some capital appreciation 
through a relatively stable asset allocation strategy targeting an income-oriented and conservative risk-return 
profile. Nuveen Asset Management generally seeks to meet the Fund&#x2019;s investment objective by investing: 
(1)&#160;approximately 20% of the Fund&#x2019;s assets in&#160;equity Underlying Funds and (2)&#160;approximately 
80% of the Fund&#x2019;s assets in fixed-income Underlying Funds. The Fund may deviate from these target 
allocations by up to ten percentage points depending upon current market conditions and outlook.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Underlying Funds&#x2019; allocation targets generally represent targets for 
investments in equity and fixed-income asset classes. Within the equity and fixed-income asset classes, 
Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors (which may 
include U.S. equity, international equity, fixed-income and short-term fixed-income) represented by various 
Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio managers 
monitor the domestic and foreign equity markets, as well as overall financial and economic conditions. 
The Fund may &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;sometimes 
be more heavily weighted toward equities or fixed-income than the target allocations, if the portfolio 
managers believe market conditions warrant. For example, the Fund may increase its holdings in fixed-income 
Underlying Funds in periods when the portfolio managers believe the equity markets will decline. The 
market sector allocations and Underlying Fund allocations may also be changed over time by the portfolio 
managers, including the addition and removal of market sectors and Underlying Funds in which the Fund 
invests in light of the Fund&#x2019;s desired level of risk and potential return at a particular time 
as evaluated by the portfolio managers based on a mix of qualitative and quantitative factors. The portfolio 
managers may also opportunistically purchase other Funds or other investment pools or investment products, 
based on the portfolio managers&#x2019; evaluation of the market sectors and/or Underlying Funds, without 
prior notice to&#160;shareholders. If 10% or more of the Fund&#x2019;s assets are expected to be invested 
in any Underlying Fund, market sector or asset class not listed in the chart below, shareholders will 
receive prior notice of such change.  &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the 
Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment pools or investment 
products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain 
exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, 
the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will 
be subject to the risks associated with the types of securities or sectors that they track, while ETNs, 
which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income 
securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, 
market sector allocations within each asset class, and Underlying Fund allocations within each market 
sector as of June 30, 2025, are listed in the chart below. These allocations may change over&#160;time. 
Underlying Fund allocations in particular may change from year to year. &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the 
date of this Prospectus, Nuveen Asset Management expects that the allocations among the market sectors 
and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements: 
(i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying 
Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions 
to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying 
Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

as well as risks related to the fixed-income markets in general, such as:&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;interest rate risk&#x2014;The 
risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;including rates that fall below zero, or a lack of market participants may lead 
to decreased liquidity and increased volatility in the fixed-income or debt markets, making it more difficult 
for the Fund to sell fixed-income investments. When interest rates change, the values of longer duration 
fixed-income securities usually change more than the values of shorter duration fixed-income securities. 
Conversely, fixed-income securities with shorter durations or maturities will be less volatile but may 
provide lower returns than fixed-income securities with longer durations or maturities. Other factors 
that may affect the value of debt securities include, but are not limited to, economic, political, public 
health, and other crises and responses by governments and companies to such crises; &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment risk&#x2014;The

payments become due. Actual or perceived changes in economic, social, public health, financial or political

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively

financial markets of emerging market countries may be very small, share prices of financial instruments 
in emerging market countries may be volatile and difficult to determine. Financial instruments of&#160;issuers

and may be more vulnerable to market manipulation. In addition, foreign investors such as a&#160;Fund 
are &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;subject to a variety of special restrictions in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;.

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of Class R6 of the Fund, 
before taxes, in each full calendar year since inception of Class R6. Because the expenses vary &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;across 
share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart 
are the best and worst returns of Class R6 for a calendar quarter during the full calendar-year periods 
covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average 
annual total returns for Class R6, Class A, Class I, Premier and Retirement classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns 
compare to those of a broad-based securities market index and a composite index based on the Fund&#x2019;s 
target allocations. For periods prior to August 1, 2026, Teachers Advisors, LLC (&#x201c;Advisors&#x201d;) 
served as investment adviser to the Fund. After-tax performance is shown only for Class R6 shares, and 
after-tax returns for the other classes of shares will vary from the after-tax returns presented for 
Class R6&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous agreements by Advisors, 
the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and certain Underlying Funds 
for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would 
have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication

shares of other Nuveen mutual funds and in other investment pools or investment products, including other 
funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen 
Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, 
LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying 
Funds&#x201d;). The Fund is designed for investors seeking long-term total return, consisting of current 
income and capital appreciation, through a relatively stable asset allocation strategy targeting a conservative 
risk-return profile. Nuveen Asset Management generally seeks to meet the Fund&#x2019;s investment objective 
by investing: (1)&#160;approximately 40% of the Fund&#x2019;s assets in&#160;equity Underlying Funds and 
(2)&#160;approximately 60% of the Fund&#x2019;s assets in fixed-income Underlying Funds. The Fund may 
deviate from these target allocations by up to ten percentage points depending upon current market conditions 
and outlook.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Underlying Funds&#x2019; allocation targets generally represent 
targets for investments in equity and fixed-income asset classes. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(which may include U.S. equity, international equity, fixed-income and short-term fixed-income) represented 
by various Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio 
managers monitor the domestic and foreign equity markets, as well as overall financial and economic conditions. 
The Fund may &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;sometimes 
be more heavily weighted toward equities or fixed-income than the target allocations, if the portfolio 
managers believe market conditions warrant. For example, the Fund may increase its holdings in fixed-income 
Underlying Funds in periods when the portfolio managers believe the equity markets will decline. The 
market sector allocations and Underlying Fund allocations may also be changed over time by the portfolio 
managers, including the addition and removal of market sectors and Underlying Funds in which the Fund 
invests in light of the Fund&#x2019;s desired level of risk and potential return at a particular time 
as evaluated by the portfolio managers based on a mix of qualitative and quantitative factors. The portfolio 
managers may also opportunistically purchase other Funds or other investment pools or investment products, 
based on the portfolio managers&#x2019; evaluation of the market sectors and/or Underlying Funds, without 
prior notice to&#160;shareholders. If 10% or more of the Fund&#x2019;s assets are expected to be invested 
in any Underlying Fund, market sector or asset class not listed in the chart below, shareholders will 
receive prior notice of such change.  &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the 
Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment pools or investment 
products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain 
exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, 
the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will 
be subject to the risks associated with the types of securities or sectors that they track, while ETNs, 
which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income 
securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, 
market sector allocations within each asset class, and Underlying Fund allocations within each market 
sector as of June 30, 2025, are listed in the chart below. These allocations may change over&#160;time. 
Underlying Fund allocations in particular may change from year to year. &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the 
date of this Prospectus, Nuveen Asset Management expects that the allocations among the market sectors 
and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements: 
(i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying 
Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions 
to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying 
Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;income or debt markets, making it more difficult for the Fund to sell fixed-income 
investments. When interest rates change, the values of longer duration fixed-income securities usually 
change more than the values of shorter duration fixed-income securities. Conversely, fixed-income securities 
with shorter durations or maturities will be less volatile but may provide lower returns than fixed-income 
securities with longer durations or maturities. Other factors that may affect the value of debt securities 
include, but are not limited to, economic, political, public health, and other crises and responses by 
governments and companies to such crises;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment risk&#x2014;The risk that, during periods of falling

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions affecting that country or region. Foreign 
investments may also be subject to risk of loss because of more or less foreign government regulation, 
less public information, less stringent investor protections and less stringent accounting, corporate 
governance, financial reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The

volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, 
market or economic developments as well as armed conflicts and can result in greater price volatility 
and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging 
or developing markets. Foreign investments may also have lower liquidity and be more difficult to value 
than investments in U.S. issuers. To the extent a Fund invests a significant portion of its assets in 
the securities of companies in a single country or region, it may be more susceptible to adverse economic, 
market, political or regulatory events or conditions affecting that country or region. Foreign investments 
may also be subject to risk of loss because of more or less foreign government regulation, less public 
information, less stringent investor protections and less stringent accounting, corporate governance, 
financial reporting and disclosure standards. Changes in the value of foreign currencies may make the 
return on an investment increase or decrease, unrelated to the quality or performance of the investment 
itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, 
trade restrictions (including tariffs) and other restrictions by the United States or other governments 
may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental 
actions or developments could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability 
to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make 
a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more difficult to value. The 
type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and 
their impact is impossible to predict;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;newer or less established than larger companies and are likely to have more limited 
resources, products and markets. Securities of small-cap companies often have lower overall liquidity 
than securities of larger companies as a result of there being a smaller market for their securities, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. Stocks of mid-capitalization 
companies often experience greater price volatility, lower trading volume and lower overall liquidity 
than the stocks of larger, more established companies;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;style risk&#x2014;The risk that use of a particular investing 
style (such as growth or value investing) may fall out of favor in the marketplace for various periods 
of time and result in underperformance relative to the broader market sector or significant declines 
in the value of a Fund&#x2019;s portfolio investments; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;dividend-paying security risk&#x2014;The risk that investments

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;more developed countries and may be more vulnerable to market manipulation.

in many emerging market&#160;countries&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;. Moreover, legal remedies for investors in emerging markets

shares of other Nuveen mutual funds and in other investment pools or investment products, including other 
funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen 
Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, 
LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying 
Funds&#x201d;). The Fund is designed for investors seeking long-term total return, consisting of capital 
appreciation and current income, through a relatively stable asset allocation strategy targeting a moderate 
risk-return profile. Nuveen Asset Management generally seeks to meet the Fund&#x2019;s investment objective 
by investing: (1)&#160;approximately 60% of the Fund&#x2019;s assets in&#160;equity Underlying Funds and 
(2)&#160;approximately 40% of the Fund&#x2019;s assets in fixed-income Underlying Funds. The Fund may 
deviate from these target allocations by up to ten percentage points depending upon current market conditions 
and outlook.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Underlying Funds&#x2019; allocation targets generally represent 
targets for investments in equity and fixed-income asset classes. Within the equity and fixed-income 
asset classes, Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors 
(which may include U.S. equity, international equity, fixed-income and short-term fixed-income) represented 
by various Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio 
managers monitor the domestic and foreign equity markets, as well as overall financial and economic conditions. 
The Fund may &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;sometimes 
be more heavily weighted toward equities or fixed-income than the target allocations, if the portfolio 
managers believe market conditions warrant. For example, the Fund may increase its holdings in fixed-income 
Underlying Funds in periods when the portfolio managers believe the equity markets will decline. The 
market sector allocations and Underlying Fund allocations may also be changed over time by the portfolio 
managers, including the addition and removal of market sectors and Underlying Funds in which the Fund 
invests in light of the Fund&#x2019;s desired level of risk and potential return at a particular time 
as evaluated by the portfolio managers based on a mix of qualitative and quantitative factors. The portfolio 
managers may also opportunistically purchase other Funds or other investment pools or investment products, 
based on the portfolio managers&#x2019; evaluation of the market sectors and/or Underlying Funds, without 
prior notice to&#160;shareholders. If 10% or more of the Fund&#x2019;s assets are expected to be invested 
in any Underlying Fund, market sector or asset class not listed in the chart below, shareholders will 
receive prior notice of such change.  &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the 
Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment pools or investment 
products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain 
exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, 
the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will 
be subject to the risks associated with the types of securities or sectors that they track, while ETNs, 
which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income 
securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, 
market sector allocations within each asset class, and Underlying Fund allocations within each market 
sector as of June 30, 2025, are listed in the chart below. These allocations may change over&#160;time. 
Underlying Fund allocations in particular may change from year to year. &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the 
date of this Prospectus, Nuveen Asset Management expects that the allocations among the market sectors 
and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements: 
(i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying 
Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions 
to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying 
Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

risk&#x2014;The risk that market prices of portfolio investments held by a Fund may fluctuate rapidly 
or unpredictably due to a variety of factors, including responses to government actions or interventions, 
or changing economic, political or market conditions. Market risk may affect a single issuer, industry 
or sector of the economy, or it &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;may affect the market as a whole. Such conditions may add 
significantly to the risk of volatility in the net asset value (&#x201c;NAV&#x201d;) of the Fund&#x2019;s 
shares and adversely affect the Fund and its investments. From time to time, a Fund may invest&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; 
a significant portion of its assets in companies in one or more related sectors or industries, which 
would make the Fund more vulnerable to adverse&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; developments affecting such sectors or

risk&#x2014;The risk that an issuer&#x2019;s earnings prospects, credit rating and overall financial position 
will deteriorate, causing a decline in the value of the issuer&#x2019;s financial instruments over short 
or extended periods of&#160;time;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;foreign investment risk&#x2014;Foreign markets can be more 
volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, 
market or economic developments as well as armed conflicts and can result in greater price volatility 
and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging 
or developing markets. Foreign investments may also have lower liquidity and be more difficult to value 
than investments in U.S. issuers. To the extent a Fund invests a significant portion of its assets in 
the securities of companies in a single country or region, it may be more susceptible to adverse economic, 
market, political or regulatory events or conditions affecting that country or region. Foreign investments 
may also be subject to risk of loss because of more or less foreign government regulation, less public 
information, less stringent investor protections and less stringent accounting, corporate governance, 
financial reporting and disclosure standards. Changes in the value of foreign currencies may make the 
return on an investment increase or decrease, unrelated to the quality or performance of the investment 
itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, 
trade restrictions (including tariffs) and other restrictions by the United States or other governments 
may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other similar governmental 
actions or developments could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability 
to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make 
a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more difficult to value. The 
type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and 
their impact is impossible to predict;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- and mid-cap risk&#x2014;The risk that the stocks of 
small-capitalization companies often experience greater price volatility than large- or mid-sized companies 
because small-cap companies are often newer or less established than larger companies and are likely 
to have more limited resources, products and markets. Securities of small-cap companies often have lower 
overall liquidity than securities of larger companies as a result of there being a smaller market for 
their securities, which can have an adverse effect on the pricing of these securities and on the ability 
to sell these securities when a Fund&#x2019;s investment adviser or sub-adviser deems it appropriate. 
Stocks of mid-capitalization companies often experience greater price &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;volatility, lower trading volume and lower overall liquidity than the stocks of

style (such as growth or value investing) may fall out of favor in the marketplace for various periods 
of time and result in underperformance relative to the broader market sector or significant declines 
in the value of a Fund&#x2019;s portfolio investments; and&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;dividend-paying security risk&#x2014;The risk that investments

as well as risks related to the fixed-income markets in general, such as:&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;interest rate risk&#x2014;The 
risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, including rates that fall below zero, or a lack of market participants 
may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making 
it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values 
of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income 
securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile 
but may provide lower returns than fixed-income securities with longer durations or maturities. Other 
factors that may affect the value of debt securities include, but are not limited to, economic, political, 
public health, and other crises and responses by governments and companies to such crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

payments become due. Actual or perceived changes in economic, social, public health, financial or political 
conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty

securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, 
political, regulatory, currency, market or economic developments as well as armed conflicts. These developments 
may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations 
to a Fund or impair a Fund&#x2019;s ability to enforce its rights against the foreign debt issuer. These 
risks are heightened in emerging or developing markets. Foreign investments may also have lower overall 
liquidity and be more difficult to value than investments in U.S. issuers. To the extent a Fund invests

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in more developed countries and may be more vulnerable to market &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;manipulation.

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of Class R6 of the Fund, 
before taxes, in each full calendar year since inception of Class R6. Because the expenses vary across 
share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart 
are the best and worst returns of Class R6 for a calendar quarter during the full calendar-year periods 
covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average 
annual total returns for Class R6, Class A, Class I, Premier and Retirement classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index based on the Fund&#x2019;s target allocations. For periods prior to August 1, 2026, Teachers Advisors, 
LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax 
returns presented for Class R6&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged,

shares of other Nuveen mutual funds and in other investment pools or investment products, including other 
funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen 
Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, 
LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying 
Funds&#x201d;). The Fund is designed for investors seeking long-term growth of capital with some current 
income through a relatively stable asset allocation strategy targeting a growth-oriented risk-return 
profile. Nuveen Asset Management generally seeks to meet the Fund&#x2019;s investment objective by investing: 
(1)&#160;approximately 80% of the Fund&#x2019;s assets in&#160;equity Underlying Funds and (2)&#160;approximately 
20% of the Fund&#x2019;s assets in fixed-income Underlying Funds. The Fund may deviate from these target 
allocations by up to ten percentage points depending upon current market conditions and outlook.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Underlying Funds&#x2019; allocation targets generally represent targets for 
investments in equity and fixed-income asset classes. Within the equity and fixed-income asset classes, 
Nuveen Asset Management allocates the Fund&#x2019;s investments to particular market sectors (which may 
include U.S. equity, international equity, fixed-income and short-term fixed-income) represented by &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;various 
Underlying Funds. To maintain an appropriate allocation among the Underlying Funds, the portfolio managers 
monitor the domestic and foreign equity markets, as well as overall financial and economic conditions. 
The Fund may sometimes be more heavily weighted toward equities or fixed-income than the target allocations, 
if the portfolio managers believe market conditions warrant. For example, the Fund may increase its holdings 
in fixed-income Underlying Funds in periods when the portfolio managers believe the equity markets will 
decline. The market sector allocations and Underlying Fund allocations may also be changed over time 
by the portfolio managers, including the addition and removal of market sectors and Underlying Funds 
in which the Fund invests in light of the Fund&#x2019;s desired level of risk and potential return at 
a particular time as evaluated by the portfolio managers based on a mix of qualitative and quantitative 
factors. The portfolio managers may also opportunistically purchase other Funds or other investment pools 
or investment products, based on the portfolio managers&#x2019; evaluation of the market sectors and/or 
Underlying Funds, without prior notice to&#160;shareholders. If 10% or more of the Fund&#x2019;s assets 
are expected to be invested in any Underlying Fund, market sector or asset class not listed in the chart 
below, shareholders will receive prior notice of such change.  &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment pools or investment 
products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain 
exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, 
the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will 
be subject to the risks associated with the types of securities or sectors that they track, while ETNs, 
which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income 
securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, 
market sector allocations within each asset class, and Underlying Fund allocations within each market 
sector as of June 30, 2025, are listed in the chart below. These allocations may change over&#160;time. 
Underlying Fund allocations in particular may change from year to year. &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the 
date of this Prospectus, Nuveen Asset Management expects that the allocations among the market sectors 
and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements: 
(i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying 
Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions 
to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying 
Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign 
securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities 
less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to predict;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- 
and mid-cap risk&#x2014;The risk that the stocks of small-capitalization companies often experience greater 
price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;Fund&#x2019;s investment adviser or sub-adviser deems it appropriate.

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment 
risk&#x2014;The risk that, during periods of falling interest rates, borrowers may pay off their mortgage

payments become due. Actual or perceived changes in economic, social, public health, financial or political 
conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty

securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, 
political, regulatory, currency, market or economic developments as well as armed conflicts. These developments 
may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations 
to a Fund or impair a Fund&#x2019;s ability to enforce its rights against the foreign debt issuer. These 
risks are heightened in emerging or developing markets. Foreign investments may also have lower overall 
liquidity and be more difficult to value than investments in U.S. issuers. To the extent a Fund invests 
a significant portion of its assets in the securities of companies in a single country or region, it 
may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting 
that country or region. Foreign investments may also be subject to risk of loss because of more or less 
foreign government regulation, less public information, less stringent investor protections and less 
stringent accounting, corporate governance, financial &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The risk that, during periods of falling interest

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in more developed countries and may be more vulnerable to market &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;manipulation.

shares of other Nuveen mutual funds and in other investment pools or investment products, including other 
funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, Nuveen 
Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen Asset Management, 
LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the &#x201c;Underlying 
Funds&#x201d;). The Fund is designed for investors seeking long-term growth of capital through a relatively 
stable asset allocation strategy targeting an aggressive growth risk-return profile. Nuveen Asset Management 
generally seeks to meet the Fund&#x2019;s investment objective by investing: (1)&#160;approximately 100% 
of the Fund&#x2019;s assets in&#160;equity Underlying Funds and (2)&#160;approximately 0% of the Fund&#x2019;s 
assets in fixed-income Underlying Funds. The Fund may deviate from these target allocations by up to 
ten percentage points depending upon current market conditions and outlook.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The 
Underlying Funds&#x2019; allocation targets generally represent targets for investments in equity and 
fixed-income asset classes. Within the equity and fixed-income asset classes, Nuveen Asset Management 
allocates the Fund&#x2019;s investments to particular market sectors (which may include U.S. equity, international 
equity, fixed-income and short-term fixed-income) represented by various Underlying Funds. To maintain 
an appropriate allocation among the Underlying Funds, the portfolio managers monitor the domestic and 
foreign equity markets, as well as overall financial and economic conditions. The Fund may sometimes 
be more heavily weighted toward equities or fixed-income than the &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;target 
allocations, if the portfolio managers believe market conditions warrant. For example, the Fund may increase 
its holdings in fixed-income Underlying Funds in periods when the portfolio managers believe the equity 
markets will decline. The market sector allocations and Underlying Fund allocations may also be changed 
over time by the portfolio managers, including the addition and removal of market sectors and Underlying 
Funds in which the Fund invests in light of the Fund&#x2019;s desired level of risk and potential return 
at a particular time as evaluated by the portfolio managers based on a mix of qualitative and quantitative 
factors. The portfolio managers may also opportunistically purchase other Funds or other investment pools 
or investment products, based on the portfolio managers&#x2019; evaluation of the market sectors and/or 
Underlying Funds, without prior notice to&#160;shareholders. If 10% or more of the Fund&#x2019;s assets 
are expected to be invested in any Underlying Fund, market sector or asset class not listed in the chart 
below, shareholders will receive prior notice of such change.  &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments 
in the Underlying Funds, the Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign 
equities of companies of various sizes and market capitalizations and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s ability to invest in other investment pools or investment 
products noted above, the Fund may invest in ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;) to gain 
exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, 
the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will 
be subject to the risks associated with the types of securities or sectors that they track, while ETNs, 
which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income 
securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s asset class allocations, 
market sector allocations within each asset class, and Underlying Fund allocations within each market 
sector as of June 30, 2025, are listed in the chart below. These allocations may change over&#160;time. 
Underlying Fund allocations in particular may change from year to year. &lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; However, as of the 
date of this Prospectus, Nuveen Asset Management expects that the allocations among the market sectors 
and Underlying Funds set forth below will be adjusted over time as Nuveen Asset Management implements: 
(i) the addition of Nuveen Small Cap Select Fund and Nuveen International Value Fund as new Underlying 
Funds in the U.S. Equity and International Equity market sectors, respectively, and corresponding reductions 
to other Underlying Funds in those market sectors; and (ii) strategic reallocations among certain Underlying 
Funds.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;  &lt;/span&gt;&lt;/p&gt;&lt;table cellpadding="0" cellspacing="0" style="border-collapse:collapse" width="100%"&gt;&lt;tr style="font-size:1pt;"&gt;&lt;td style="width:12.99%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:9.01%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:19.12%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.54%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:.88%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:40%;"&gt;&#160;&lt;/td&gt;&lt;td style="width:8.58%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:bottom; border-bottom:1pt; border-bottom-style:solid; border-bottom-color:#000000;"&gt;&lt;p style="font-size:7.5pt; font-family:Sans-Serif; text-align:left; font-weight:bold; text-decoration:none;"&gt;Asset

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign 
securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments in such securities 
less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures 
that may be imposed could vary broadly in scope, and their impact is impossible to predict;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;small- 
and mid-cap risk&#x2014;The risk that the stocks of small-capitalization companies often experience greater 
price volatility than large- or mid-sized companies because small-cap companies are often newer or less 
established than larger companies and are likely to have more limited resources, products and markets. 
Securities of small-cap companies often have lower overall liquidity than securities of larger companies 
as a result of there being a smaller market for their securities, which can have an adverse effect on 
the pricing of these securities and on the ability to sell these securities when a &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;Fund&#x2019;s investment adviser or sub-adviser deems it appropriate.

rate risk&#x2014;The risk that changes in interest rates can adversely affect the value or liquidity of, 
and income generated by, fixed-income investments. This risk is heightened to the extent a Fund invests 
in longer duration fixed-income investments and during periods when prevailing interest rates are changing. 
There is a risk that interest rates across the financial system may change, possibly significantly and/or 
rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market 
participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, 
making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the 
values of longer duration fixed-income securities usually change more than the values of shorter duration 
fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will 
be less volatile but may provide lower returns than fixed-income securities with longer durations or 
maturities. Other factors that may affect the value of debt securities include, but are not limited to, 
economic, political, public health, and other crises and responses by governments and companies to such 
crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

payments become due. Actual or perceived changes in economic, social, public health, financial or political

securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, 
political, regulatory, currency, market or economic developments as well as armed conflicts. These developments 
may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations 
to a Fund or impair a Fund&#x2019;s ability to enforce its rights against the foreign debt issuer. These 
risks are heightened in emerging or developing markets. Foreign investments may also have lower overall 
liquidity and be more difficult to value than investments in U.S. issuers. To the extent a Fund invests 
a significant portion of its assets in the securities of companies in a single country or region, it 
may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting 
that country or region. Foreign investments may also be subject to risk of loss because of more or less 
foreign government regulation, less public information, less stringent investor protections and less 
stringent accounting, corporate governance, financial &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;reporting and disclosure standards. Changes in the value of foreign currencies 
may make the return on an investment increase or decrease, unrelated to the quality or performance of 
the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) and other restrictions by the United States and 
other governments may also negatively impact a Fund&#x2019;s investments. Economic sanctions and other 
similar governmental actions or developments could, among other things, effectively restrict or eliminate 
a Fund&#x2019;s ability to purchase or sell certain foreign securities or groups of foreign securities, 
and/or thus may make a Fund&#x2019;s investments in such securities less liquid (or illiquid) or more 
difficult to value. The type and severity of sanctions and other measures that may be imposed could vary 
broadly in scope, and their impact is impossible to predict; and&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;call risk&#x2014;The risk that, during periods of falling interest

of foreign investment often increases in countries with emerging markets or those economically tied to 
emerging market countries. For example, these countries may have more unstable governments than developed 
countries, and their economies may be based on only a few industries. Emerging market countries may also 
have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, 
which would affect a Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there 
could be less information available about issuers in emerging market countries, which could negatively 
affect Nuveen Asset Management&#x2019;s ability to evaluate local companies or their potential impact 
on a Fund&#x2019;s performance. Because the financial markets of emerging market countries may be very 
small, share prices of financial instruments in emerging market countries may be volatile and difficult 
to determine. Financial instruments of&#160;issuers in these countries may have lower overall liquidity 
than those of issuers in more developed countries and may be more vulnerable to market &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;manipulation.

and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund&#x2019;s 
performance from year to year. The bar chart shows the annual total returns of Class R6 of the Fund, 
before taxes, in each full calendar year since inception of Class R6. Because the expenses vary across 
share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart 
are the best and worst returns of Class R6 for a calendar quarter during the full calendar-year periods 
covered by the bar chart. The performance table following the bar chart shows the Fund&#x2019;s average 
annual total returns for Class R6, Class A, Class I, Premier and Retirement classes over the applicable 
one-year, five-year, ten-year and since-inception periods ended &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index based on the Fund&#x2019;s target allocations. For periods prior to August 1, 2026, Teachers Advisors, 
LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax 
returns presented for Class R6&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, 
expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For current performance information of each share class, including

that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses, before fee 
waivers and/or expense reimbursements, remain the same. The example assumes that the Fund&#x2019;s fee

shares of other Nuveen mutual funds and in other investment pools or&#160;investment products, including 
other funds or exchange-traded funds (&#x201c;ETFs&#x201d;) advised by the Fund&#x2019;s investment adviser, 
Nuveen Fund Advisors, LLC (&#x201c;Nuveen Fund Advisors&#x201d;), the Fund&#x2019;s sub-adviser, Nuveen 
Asset Management, LLC (&#x201c;Nuveen Asset Management&#x201d;), or their affiliates (collectively, the 
&#x201c;Underlying Funds&#x201d;). The Fund invests&#160;in Underlying Funds according to a relatively 
stable asset allocation strategy and will generally seek to meet its investment objective by investing: 
(1)&#160;approximately 60.00% of its assets in equity Underlying Funds, including up to 5.00% of its 
assets in real estate Underlying Funds; and (2)&#160;approximately 40.00% of its assets in fixed-income 
Underlying Funds (&#x201c;target&#160;allocations&#x201d;).&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund may invest 
in the following equity Underlying Funds: Nuveen Core Equity Fund, Nuveen Large Cap Growth Fund, Nuveen 
Large Cap Value Fund, Nuveen Quant International Small Cap Equity Fund, Nuveen Quant Small Cap Equity 
Fund, Nuveen Quant Small/Mid Cap Equity Fund, Nuveen Emerging Markets Equity Fund, Nuveen International 
Equity Fund, Nuveen International Opportunities Fund, Nuveen Real Estate Securities Select Fund, Nuveen 
Dividend Growth Fund, Nuveen Dividend Value Fund, Nuveen Small Cap Select Fund, Nuveen International 
Value Fund and Nuveen Growth Opportunities ETF.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund may invest 
in the following fixed-income Underlying Funds: Nuveen Core Plus Bond Fund, Nuveen High Yield Fund, Nuveen 
Inflation Linked Bond Fund, Nuveen International Bond Fund, Nuveen Money Market Fund and Nuveen Short 
Term Bond Fund.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As a result of its investments in the Underlying Funds, the 
Fund&#x2019;s returns will reflect investments in a mix of domestic and foreign equities of companies 
of various sizes and market capitalizations, real estate securities and a variety of domestic and foreign 
fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. 
To maintain an appropriate allocation among the Underlying Funds, the portfolio managers monitor the 
foreign and domestic equity markets, as well as overall financial and economic conditions. If the portfolio 
managers believe that the relative attractiveness of the markets in which the equity and fixed-income 
funds are invested changes, they can adjust the percentage of investments in the Fund&#x2019;s market 
sectors or Underlying Funds up or down by up to 10%; they may also invest in new market &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;sectors 
or Underlying Funds without prior notice to shareholders. If 10% or more of the Fund&#x2019;s assets are 
expected to be invested in any Underlying Fund or market sector not listed above or in the chart below, 
shareholders will receive prior notice of such change. At any given time the Fund may hold between 0% 
to 5% of its assets in real estate funds. The Fund&#x2019;s composite benchmark is a composite of three 
benchmark indices representing three types of market sectors within the equity and fixed-income Underlying 
Fund asset classes, i.e., domestic equity, international equity and fixed-income. The composite index 
is created by applying the results of the benchmark for each of these three market sectors in proportion 
to the Fund&#x2019;s target allocations among the three market sectors. For more information about the 
different indices that comprise the Fund&#x2019;s composite benchmark index, please see the &#x201c;Additional 
information about the Fund&#x2019;s composite index&#x201d; section of this Prospectus.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The 
composition of the Fund&#x2019;s fixed-income portion will vary depending on the shape of the yield curve. 
This means that when there is not much difference between the yield on short-term and long-term bonds, 
the Fund would normally increase its investments in the Nuveen Short Term Bond Fund. The Fund will have 
less than 5% of its assets in the Nuveen High Yield Fund.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The Fund might sometimes 
be even more heavily weighted toward equities or fixed-income, if Nuveen Asset Management believes market 
conditions warrant. For example, the Fund might increase its holdings in fixed-income funds in periods 
when Nuveen Asset Management believes equity markets will decline.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;As part of the Fund&#x2019;s 
ability to invest in other investment pools or investment products noted above, the Fund may invest in 
ETFs and exchange-traded notes (&#x201c;ETNs&#x201d;). The Fund may use investments in ETFs and ETNs to 
gain exposure to various market sectors or securities in order to effect its asset allocation strategy. 
Additionally, the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs 
and ETNs will be subject to the risks associated with the types of securities or sectors that they track, 
while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks 
of fixed-income securities, including credit risk.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;For flexibility in meeting 
redemptions, expenses and the timing of new investments, and as a short-term defense during periods of 
unusual volatility, the Fund may invest in government securities (as defined in the Investment Company 
Act of 1940, as amended (the &#x201c;1940 Act&#x201d;)), short-term paper or shares of the Nuveen Money 
Market Fund. For temporary defensive purposes, the Fund may invest without limitation in such securities. 
The Fund cannot guarantee that this strategy will be successful.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The Fund&#x2019;s 
asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations 
within each market sector, as of June 30, 2025, are listed in the chart below. These allocations may 
change over&#160;time. Underlying Fund allocations in particular may change from year to year.&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt; 
However, as of the date of this Prospectus, Nuveen Asset Management expects that the allocations among 
the market sectors and Underlying Funds &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:bold; text-decoration:none;"&gt;set 
forth below will be adjusted over time as Nuveen Asset Management implements: (i) the addition of Nuveen 
Small Cap Select Fund and Nuveen International Value Fund as new Underlying Funds in the U.S. Equity

investment risk&#x2014;Foreign markets can be more volatile than the U.S. market due to increased risks 
of adverse issuer, political, regulatory, currency, market or economic developments as well as armed 
conflicts and can result in greater price volatility and perform differently from financial instruments 
of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may 
also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent 
a Fund invests a significant portion of its assets in the securities of companies in a single country 
or region, it may be more susceptible to adverse economic, market, political or regulatory events or 
conditions affecting that country or region. Foreign investments may also be subject to risk of loss 
because of more or less foreign government regulation, less public information, less stringent investor 
protections and less stringent accounting, corporate governance, financial reporting and disclosure standards. 
Changes in the value of foreign currencies may make the return on an investment increase or decrease, 
unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange 
controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) 
and other restrictions by the United States or other governments may also negatively impact a Fund&#x2019;s 
investments. Economic sanctions and other similar governmental actions or developments could, among other 
things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell certain foreign

risk that changes in interest rates can adversely affect the value or liquidity of, and income generated 
by, fixed-income investments. This risk is heightened to the extent a Fund invests in longer duration 
fixed-income investments and during periods when prevailing interest rates are changing. There is a risk 
that interest rates across the financial system may change, possibly significantly and/or rapidly. In 
general, changing interest rates, including rates that fall below zero, or a lack of market participants 
may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making 
it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values 
of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income 
securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile 
but may provide lower returns than fixed-income securities with longer durations or maturities. Other 
factors that may affect the value of debt securities include, but are not limited to, economic, political, 
public health, and other crises and responses by governments and companies to such crises;&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:-6.5pt; font-weight:normal; margin-left:46.1pt; font-style:normal;"&gt;&lt;span style="font-size:7.0pt; font-family:Symbol; font-style:normal; font-weight:normal; text-decoration:none;"&gt;&#xb7;&lt;/span&gt;&lt;span style="word-spacing:4.25pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;prepayment

foreign investment risk&#x2014;Investment in fixed-income securities or financial instruments of foreign 
issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic 
developments as well as armed conflicts. These developments may impact the ability of a foreign debt 
issuer to make timely and ultimate payments on its debt obligations to a Fund or impair a Fund&#x2019;s 
ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging 
or developing markets. Foreign investments may also have lower overall liquidity and be more difficult 
to value than investments in U.S. issuers. To the extent a Fund invests a significant portion of its 
assets in the securities of companies in a single country or region, it may be more susceptible to adverse 
economic, market, political or regulatory events or conditions &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:46.1pt; text-decoration:none;"&gt;affecting that country or region. Foreign investments may also be subject to risk 
of loss because of more or less foreign government regulation, less public information, less stringent 
investor protections and less stringent accounting, corporate governance, financial reporting and disclosure 
standards. Changes in the value of foreign currencies may make the return on an investment increase or 
decrease, unrelated to the quality or performance of the investment itself. The imposition of sanctions, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) and other restrictions by the United States and other governments may also negatively impact 
a Fund&#x2019;s investments. Economic sanctions and other similar governmental actions or developments 
could, among other things, effectively restrict or eliminate a Fund&#x2019;s ability to purchase or sell 
certain foreign securities or groups of foreign securities, and/or thus may make a Fund&#x2019;s investments 
in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions 
and other measures that may be imposed could vary broadly in scope, and their impact is impossible to

with emerging markets or those economically tied to emerging market countries. For example, these countries 
may have more unstable governments than developed countries, and their economies may be based on only 
a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, 
financial reporting and recordkeeping requirements, which would affect a Fund&#x2019;s ability to evaluate 
potential portfolio companies. As a result, there could be less information available about issuers in 
emerging market countries, which could negatively affect Nuveen Asset Management&#x2019;s ability to evaluate 
local companies or their potential impact on a Fund&#x2019;s performance. Because the financial markets 
of emerging market countries may be very small, &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; margin-left:39.6pt; font-style:normal;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;share prices of financial instruments in emerging market countries may be volatile

risks of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year. 
The bar chart shows the annual total returns of Class R6 of the Fund, before taxes, in each full calendar 
year for the last ten years. Because the expenses vary across share classes, the performance of Class 
R6 may vary from the other share classes. Below the bar chart are the best and worst returns of Class 
R6 for a &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;calendar 
quarter during the full calendar-year periods covered by the bar chart. The performance table following 
the bar chart shows the Fund&#x2019;s average annual total returns for Class R6, Class A and Retirement 
classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 
31, 2024, and how those returns compare to those of a broad-based securities market index and a composite 
index based on the Fund&#x2019;s target allocations. For periods prior to August 1, 2026, Teachers Advisors, 
LLC (&#x201c;Advisors&#x201d;) served as investment adviser to the Fund. After-tax performance is shown 
only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax 
returns presented for Class R6&#160;shares. &lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; text-decoration:none;"&gt;The returns shown below reflect previous 
agreements by Advisors, the Fund&#x2019;s prior investment adviser, to waive or reimburse the Fund and 
certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the 
returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not 
necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, 
and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, 
expenses or taxes.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.5pt; font-family:Sans-Serif; text-align:left; text-indent:12.25pt; font-weight:normal; font-style:italic;"&gt;&lt;span style="font-size:9.5pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;For current performance information of each share class, including
