&lt;span style="font-weight: normal"&gt;This example is intended to help you compare the cost of investing in 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 of
your shares at the end of those periods, that your investment has a 5% return each year, and that the fund&#x2019;s operating expenses
remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the
previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which
the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions
your costs would be:&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

fund focuses on bonds issued by the U.S. Treasury (e.g., Treasury Inflation Protected Securities), but similar bonds issued by U.S. government
agencies and corporations may also be purchased. The fund may invest up to 20% of its net assets in inflation protected bonds issued
by foreign governments or corporations, including governments and corporations in emerging markets, and linked to a non-U.S. inflation
rate. The fund may also invest up to 20% of its net assets in fixed income securities that are not indexed to inflation. All of the non-U.S.
Treasury securities purchased by the fund will be rated investment grade (BBB or better, or an equivalent rating) by at least one credit
rating agency or, if unrated, deemed by the adviser to be of comparable quality. The fund may continue to hold a security that has been
downgraded after purchase. The fund may purchase securities of any maturity and its weighted average maturity will vary with market conditions.&lt;/span&gt;&lt;/p&gt;

Inflation Protected Securities, known as TIPS, are instruments issued by the U.S. Treasury that are structured to provide protection
against inflation, which measures a sustained increase in the prices of goods and services in an economy that can erode the purchasing
power of a currency over time. Interest and principal payments of TIPS are periodically adjusted in step with changes in the inflation
rate. These inflation adjustments for TIPS are applied based on changes in the Consumer Price Index (CPI), while inflation adjustments
for other types of inflation-linked securities may be based on a different inflation index. Inflation-linked securities tend to react
to changes in real interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation. For example,
if a 3-year Treasury bond is yielding 5% and inflation expectations for the next 3 years are 2%, the real interest rate is 3%.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
selecting securities, the portfolio managers may consider implied inflation rates (the difference in yield between conventional fixed-rate
Treasury bonds and TIPS of comparable maturity). For instance, if the implied inflation rate appears high relative to actual or anticipated
inflation, the portfolio managers may sell TIPS in favor of conventional fixed-rate Treasuries. Depending on the outlook for both inflation
and economic growth, the portfolio managers may also purchase and sell TIPS and other securities to change the fund&#x2019;s duration,
which measures its overall sensitivity to interest rate changes.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
fund may use a variety of derivatives, such as futures, options, foreign exchange currency contracts (forwards), and swaps for a number
of purposes, such as for hedging risk or managing certain exposure. Specifically, the fund uses interest rate futures and CPI swaps,
or other inflation swaps. Interest rate derivatives are typically used to manage the fund&#x2019;s exposure to interest rate changes or
to adjust portfolio duration. CPI swaps, which are derivatives pegged directly to the rate of inflation, would typically be used to manage
the fund&#x2019;s inflation risk or maintain efficient exposure to TIPS and other inflation-linked securities.&lt;/span&gt;&lt;/p&gt;

an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed
income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund&#x2019;s

securities:&lt;/b&gt; In general, the value of an inflation-linked security, including TIPS, will typically decrease when real interest rates
(nominal interest rates reduced by the expected impact of inflation) increase and increase when real interest rates decrease. When inflation
is negative or concerns over inflation are low, the value and income of inflation-linked securities could fall and result in losses for
the fund and during periods of very low inflation, the yield on an inflation-linked security may be negative. Conversely, during sustained
periods of high inflation, the fund&#x2019;s yield should increase, which may not be repeated. Funds that invest heavily in inflation-linked
securities do not always move in lockstep with inflation because they do not necessarily buy inflation-linked securities when they are
originally issued or hold them until maturity. In addition, the accrual of inflation adjustments on the fund&#x2019;s holdings may significantly
impact the current level of dividends actually paid to shareholders. Changes in inflation rates and/or interest rates may cause the fund&#x2019;s
yield to vary substantially over time.&lt;/span&gt;&lt;/p&gt;

conditions:&lt;/b&gt; The value of the fund&#x2019;s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an

the fund&#x2019;s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions,
and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters,
and outbreaks of infectious illnesses or other widespread public health issues (such as pandemics) and related governmental and public
responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets,
while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government
intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad
declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.&lt;/span&gt;&lt;/p&gt;

rates:&lt;/b&gt; A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely,
a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and
yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds
with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks
and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;The use of derivatives exposes the fund to additional volatility and potential losses and the fund may not achieve the purpose of
using the derivative. A derivative involves risks different from, and possibly greater than, the risks associated with investing directly
in the reference or assets on which the derivative is based, including liquidity risk, valuation risk, correlation risk, market risk,
interest rate risk, leverage risk, counterparty and credit risk, operational risk, management risk, legal risk, and regulatory risk.
Derivatives can be highly volatile, illiquid, and difficult to value, and changes in the value of a derivative may not properly correlate
with changes in the value of the underlying asset, reference rate, or index. The fund could be exposed to significant losses if it is
unable to close a derivatives position due to the lack of a liquid secondary trading market. The prices of derivatives may move in unexpected
ways, especially in abnormal market conditions. Derivatives also expose the fund to settlement risk, such as if the fund is required
to acquire, buy, or sell the underlying reference or asset at an undesirable price, has challenges with offsetting transactions, or risks
associated with cash settlement. Certain derivatives are also subject to counterparty risk, which is the risk that the derivative counterparty
will not fulfill its contractual obligations. The use of derivatives includes the risk of potential operational issues. Derivatives are
exposed to legal risks, such as the legality or enforceability of a contract. The adviser may not be able to accurately predict the direction
of prices, economic factors, or other associated risks which could cause loss in value or impair the fund&#x2019;s efforts to reduce overall
volatility. New regulations may make derivatives more costly, limit availability, or otherwise affect their value or performance.&lt;/span&gt;&lt;/p&gt;

investing: &lt;/b&gt;&lt;span style="font-weight: normal"&gt;Non-U.S.&lt;/span&gt; securities tend to be more volatile and have lower overall liquidity
and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments
overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers
are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and
settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk.
Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets.
Investments in emerging market countries are subject to greater risk and overall volatility than investments in developed markets.&lt;/span&gt;&lt;/p&gt;

breaches:&lt;/b&gt; The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to
the fund&#x2019;s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause
one of the fund&#x2019;s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of

calculate its net asset value, and satisfy redemptions.&lt;/span&gt;&lt;/p&gt;
