During periods of unfavorable market conditions, the minimum portion of the Fund&#x2019;s net assets invested in non-U.S. securities will be reduced to 50% of the MSCI World Value Index&#x2019;s non-U.S. assets. The Fund will invest in securities of companies representing at least three different countries (one of which may be the United States). The Fund may invest up to 20% of its net assets in securities of companies located in emerging markets. The Fund may invest in securities issued by companies of any market capitalization, including small- and mid-capitalization companies.&lt;/div&gt;  &lt;div style="font-size: 10.0pt; font-family: arial; text-align: left; color: #000000; font-weight: normal; text-decoration: none; margin-top: 1em; margin-bottom: 1em;"&gt;The Fund may utilize the following derivatives: currency options, currency futures and options on such futures, and currency forwards.

Derivative instruments can be used to acquire or to transfer the risk and returns of a security or other asset without buying or selling the security or asset, and the risks associated with investing in such derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An over-the-counter derivative transaction between the Fund and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Fund to the creditworthiness of the central counterparty. Derivatives used by the Fund are expected to be counted towards the Fund's 80% policy to the extent they provide investment exposure to investments within that policy or to one or more of the market risk factors associated with investments within that policy.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Depending on market conditions, dividend paying securities that meet the Fund&#x2019;s investment objectives may not be widely available or may be &lt;/span&gt;&lt;/div&gt;  &lt;div style="font-size: 10.0pt; font-family: arial; text-align: left; color: #000000; font-weight: normal; text-decoration: none; margin-top: 1em; margin-bottom: 1em;"&gt;concentrated in only a few market sectors.

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 the Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund&#x2019;s sub-adviser to evaluate local companies or their potential impact on the Fund&#x2019;s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. &lt;/span&gt;&lt;span style="font-size: 10.0pt; font-family: arial; font-style: normal; color: #000000; font-weight: normal; text-decoration: none;"&gt;Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Changing interest rates, or anticipated changes to interest rates, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund&#x2019;s performance to the extent that it is exposed to such interest rates. Fixed-rate securities may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. When interest rates change, the values of longer-duration fixed-rate securities usually change more than the values of shorter-duration fixed-rate securities. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. The Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation. There is a risk that interest rates across the financial system may change, possibly significantly and/or &lt;/span&gt;&lt;/div&gt;  &lt;div style="font-size: 10.0pt; font-family: arial; text-align: left; color: #000000; font-weight: normal; text-decoration: none; margin-top: 1em; margin-bottom: 1em;"&gt;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-rate or debt markets, making it more difficult for the Fund to sell fixed-rate investments. Changes in interest rates may also lead to an increase in Fund redemptions, which may result in higher portfolio turnover costs, thereby adversely affecting the Fund&#x2019;s performance.&lt;/div&gt; </oef:RiskTextBlock>

In addition, federal banking regulations may cause certain dealers to reduce their inventories of securities, which may further decrease the Fund&#x2019;s ability to buy or sell securities. As a result of this decreased liquidity, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance.

The debt securities in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including price quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund will be able to buy or sell a portfolio security at the price established by the pricing service, which could result in a gain or loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional &#x201c;round lot&#x201d; size, but some trades may occur in smaller, &#x201c;odd lot&#x201d; sizes, often at lower prices than institutional round lot trades. Over certain time periods, such differences could materially impact the performance of the Fund, which may not be sustainable. Alternative pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund were to change pricing services, or if the Fund&#x2019;s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund&#x2019;s net asset value.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

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 the Fund&#x2019;s ability to evaluate potential portfolio companies.

Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.&lt;/div&gt;</oef:RiskTextBlock>

Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund&#x2019;s sub-adviser to evaluate local companies or their potential impact on the Fund&#x2019;s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries.

Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses are at the lesser of Total Annual Fund Operating Expenses or the applicable expense limitation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:&lt;/div&gt;</oef:ExpenseExampleNarrativeTextBlock>

Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund&#x2019;s sub-adviser to evaluate local companies or their potential impact on the Fund&#x2019;s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.&lt;/div&gt;</oef:RiskTextBlock>

Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers.

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. &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund&#x2019;s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund&#x2019;s sub-adviser to evaluate local companies or their potential impact on the Fund&#x2019;s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.&lt;/div&gt;</oef:RiskTextBlock>

However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 shares will be less than the expense limitation. The expense limitation expiring July 31, 2028 may be terminated or modified prior to that date only with the approval of the Board of Trustees of the Fund. The expense limitation in effect thereafter may be terminated or modified only with the approval of shareholders of the Fund.</link:footnote>
