Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 36.62% of the average value of its portfolio.

SUMMARY PROSPECTUS

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in investments of smaller companies located outside the U.S., including emerging markets. For purposes of this 80% policy, smaller companies are defined as those with market capitalizations that do not exceed $4 billion. However, under normal conditions, when making an initial purchase of securities of a company, the investment manager will only invest in securities of companies with a market capitalization of not more than $2 billion. Once a security qualifies for initial purchase, it continues to qualify for additional purchases as long as it is held by the Fund, provided that the issuer's market capitalization does not exceed $4 billion. In addition, the Fund may continue to hold securities that have grown to have a market capitalization in excess of $4 billion. The result may be that the Fund could hold a significant percentage of its net assets in securities of companies that have market capitalizations in excess of $2 billion. The Fund predominantly invests in equity securities, primarily common stock.

The Fund may invest more than 25% of its assets in the securities of issuers located in any one country. From time to time, based on economic conditions, the Fund may have significant investments in one or more countries, such as Japan, or in particular sectors, such as the consumer discretionary and the industrials sectors.

When choosing equity investments for the Fund, the investment manager applies a "bottom-up," value-oriented, long-term approach, focusing on the market price of a company's securities relative to the investment manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The investment manager also considers a company's price/earnings ratio, profit margins and liquidation value.

In selecting securities for the Fund, the investment manager attempts to identify those companies that offer above-average opportunities for capital appreciation in various countries and industries where economic and political factors, including currency movements, are favorable to capital growth.

The investment manager may consider selling an equity security when it believes the security has become overvalued due to either its price appreciation or changes in the company's fundamentals, when the investment manager believes that the market capitalization of a security has become too large, or when the investment manager believes another security is a more attractive investment opportunity.

Principal Risks

SUMMARY PROSPECTUS

insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Small Capitalization Companies: Securities issued by small capitalization companies may be more volatile in price than those of larger companies and may involve substantial risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, small capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans. The markets for securities issued by small capitalization companies also tend to be less liquid than the markets for securities issued by larger companies.

Foreign Securities (non-U.S.): Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments - e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; diplomatic and political developments could affect the economies, industries, and securities and currency markets of the countries in which the Fund is invested, which can include rapid and adverse political changes; social instability; regional conflicts; sanctions imposed by the United States, other nations or other governmental entities, including supranational entities; terrorism; and war; (ii) trading practices - e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information - e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets - e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies - e.g., fluctuations may negatively affect investments denominated in foreign currencies

and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

Regional: To the extent that the Fund invests a significant portion of its assets in a specific geographic region or a particular country, including Europe and Japan, the Fund will generally have more exposure to the specific regional or country risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a substantial portion of the Fund's assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund's investments. Adverse conditions in a certain region or country can adversely affect securities of issuers in other countries whose economies appear to be unrelated. Current uncertainty concerning the economic consequences of Russia's military invasion of Ukraine in February 2022 has increased market volatility.

Developing Market Countries: The Fund's investments in securities of issuers in developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Value Style Investing: A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur or do not have the anticipated effect.

Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund's ability to sell such securities or other investments when necessary to meet the Fund's liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

Focus: To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investments from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund

that invests in a wider variety of countries, regions, industries, sectors or investments.

Large Redemptions: The Fund may experience adverse effects when shareholders make large redemptions from the Fund that equate to a large percentage of the Fund's assets. In order to meet such redemption requests, the Fund may need to sell securities at times when it would not otherwise do so, which could result in losses to the Fund, increase the Fund's transaction costs and expense ratios, and accelerate the realization of taxable income, if any, to shareholders. When experiencing a large redemption, the Fund may seek to delay payment of the redemption request up to seven days for a variety of reasons including to provide the investment manager with time to orderly process the request. If, however, the Fund is unable to delay the redemption request, for example, due to various automated processes that can occur with respect to certain large redemptions, there is a risk of additional detriment to the Fund and its remaining shareholders.

Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other
