The Fund pursues its goal by investing primarily in:

Generally, the Fund acquires obligations that mature between one and ten years from the date of settlement. The Fund has a non-fundamental investment policy to invest, under normal circumstances, at least 80% of its net assets in fixed income securities issued in the U.S. The Sub-Adviser defines “fixed income securities” to include the instruments listed above.

During normal market conditions, the Fund will seek to maintain an average portfolio duration within minus half a year to plus one year (-0.5 to 1.0 years) of the average duration of the Morningstar^® US 1-3 Year Government and Corporate Bond Index^SM. As of September 30, 2026, the average duration of the index was 1.75 years. Duration is

a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. For example, if the Fund has an average duration of 5 years, the Fund’s net asset value is expected to drop by approximately 5% if interest rates were to increase by 1%.

The Fund generally invests in fixed income securities that are rated investment grade. The Fund considers fixed income securities to be investment grade if, at the time of investment, they are rated at least BBB- by S&P Global Ratings (“S&P”), Baa3 by Moody’s Ratings (“Moody’s”), or BBB- by Fitch Ratings Inc. (“Fitch”) or, if unrated, have been determined by Dimensional Fund Advisors LP (the “Sub-Adviser”) to be of comparable quality.

With respect to corporate debt securities (e.g., bonds and debentures), the Fund generally invests in investment grade securities that are issued by U.S. issuers and dollar-denominated obligations of foreign issuers issued in the U.S.

The Fund may invest in U.S. Treasury bonds, bills and notes and obligations of federal agencies or instrumentalities, including inflation-protected securities such as Treasury Inflation-Protected Securities (TIPS). Normally, the Fund may invest up to 20% of its net assets in TIPS. Some U.S. government obligations that the Fund may invest in, such as Treasury bills, notes and bonds and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the United States, while others such as those of or guaranteed by the Federal Home Loan Banks, Federal Home Loan Mortgage Corporation and Federal National Mortgage Association are not.

The Fund will invest more than 25% of its total assets in dollar-denominated obligations of U.S. banks and U.S. subsidiaries and branches of foreign banks and bank holding companies when the yield to maturity on these investments exceeds the yield to maturity on all other eligible portfolio investments of similar quality for a period of five consecutive days during which the New York Stock Exchange (“NYSE”) is open for trading. To determine that yields on dollar-denominated bank obligations are more attractive than yields on all other eligible portfolio investments of similar quality, the Sub-Adviser will examine the yield to maturity information for available fixed income securities of other industry sectors as compared to bank obligations after eliminating individual securities in each industry sector that would not be eligible for investment by the Fund. If the yield to maturity for eligible bank obligations is higher than that of eligible portfolio investments of similar quality of all other industry sectors, investments in bank obligations will be considered to have a yield that generally exceeds the yield on other eligible investments as a group. When investments in such bank obligations exceed 25% of the Fund’s total assets, the Fund’s investments will be concentrated in the banking industry.

The types of bank and bank holding company obligations in which the Fund may invest include, without limitation: dollar-denominated certificates of deposit, bankers’ acceptances, commercial paper, repurchase agreements and other debt obligations that mature between one and ten years of the date of settlement, provided such obligations meet the Fund’s established credit rating or other criteria. Commercial paper and certificates of deposit must, at the time of investment, be rated at least A-3 by S&P, P-3 by Moody’s or F3 by Fitch or, if unrated, issued by a corporation having an outstanding unsecured debt issue rated at least BBB- by S&P or Fitch or Baa3 by Moody’s.

All ratings described above apply at the time of investment.

To achieve the Fund’s investment objective, Dimensional Fund Advisors LP (the “Sub-Adviser”) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Fund’s design emphasizes long-term drivers of expected returns identified by the Sub-Adviser’s research, while balancing risk through broad diversification across companies and sectors. The Sub-Adviser’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The Fund is designed to purchase a broad and diverse group of readily marketable equity securities listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. The Sub-Adviser limits the universe of eligible securities in which the Fund may invest to those of companies whose market capitalizations generally are either in the highest 96% of total market capitalization or companies whose market capitalizations are larger than the 1,500^th largest U.S. company, whichever results in the higher market capitalization threshold. Under the Sub-Adviser’s market capitalization guidelines described above, based on market capitalization data as of August 31, 2026, the market capitalization of an eligible company would be approximately $6.0 billion or above. This dollar amount will vary due to market conditions. The Fund has a non-fundamental investment policy to invest, under normal circumstances, at least 80% of its net assets in U.S. securities. The Sub-Adviser generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser.

The Sub-Adviser uses a market capitalization weighted approach to weight the securities in the Fund’s portfolio. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Fund than companies with relatively lower market capitalizations. The Fund may emphasize certain stocks, including higher profitability stocks, as compared to their representation in the U.S. market. An equity issuer is considered to have high profitability primarily because it has high earnings or profits from operations in relation to its book value or

assets. In assessing profitability, the Sub-Adviser will consider additional information such as a company’s growth in profits. The criteria the Sub-Adviser uses for assessing profitability are subject to change from time to time.

The Sub-Adviser may also increase or reduce the Fund’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Sub-Adviser considers ratios such as recent changes in assets divided by total assets. The criteria the Sub-Adviser uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Sub-Adviser seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The Fund may also invest up to 5% of its total assets (measured at the time of purchase) in the U.S. Micro Cap Portfolio, a portfolio of DFA Investment Dimensions Group Inc., a separate registered investment company. The Sub-Adviser is also the adviser of the U.S. Micro Cap Portfolio. The U.S. Micro Cap Portfolio generally will purchase a broad and diverse group of securities of micro cap companies listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser.

The Fund may lend its portfolio securities to generate additional income.

The Fund is designed to purchase a broad and diverse group of readily marketable equity securities of small cap companies listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. The Fund has a non-fundamental investment policy to invest, under normal circumstances, at least 80% of its net assets in securities of U.S. small cap companies. The Sub-Adviser generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. The Sub-Adviser defines U.S. small cap companies to mean companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization threshold. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser.  Under the Sub-Adviser’s market capitalization guidelines described above, based on market capitalization data as of August 31, 2026, the market capitalization of an eligible company would be approximately $18.7 billion or below. This dollar amount will vary due to market conditions.

The Sub-Adviser uses a market capitalization weighted approach to weight the securities in the Fund’s portfolio. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger

proportion of the Fund than companies with relatively lower market capitalizations. The Fund may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks, as compared to their representation in the small-cap segment of the U.S. market. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Sub-Adviser may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability primarily because it has high earnings or profits from operations in relation to its book value or assets. In assessing profitability, the Sub-Adviser will consider additional information such as a company’s growth in profits. The criteria the Sub-Adviser uses for assessing relative price and profitability are subject to change from time to time.

The Sub-Adviser may also increase or reduce the Fund’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Sub-Adviser considers ratios such as recent changes in assets divided by total assets. The criteria the Sub-Adviser uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Sub-Adviser seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The Fund may lend its portfolio securities to generate additional income.

Instead of buying securities directly, the Fund invests substantially all of its assets in the DFA Portfolio, which is managed by the Sub-Adviser and has the same investment objective and investment policies as the Fund. The DFA Portfolio seeks to provide investors with access to securities portfolios consisting of a broad range of equity securities of primarily small Japanese, United Kingdom, Continental European, Asia Pacific and Canadian companies. The DFA Portfolio invests substantially all of its assets in: The Japanese Small Company Series (the “Japanese Series”), The United Kingdom Small Company Series (the “United Kingdom Series”), The Continental Small Company Series (the “Continental Series”), The Asia Pacific Small Company Series (the “Asia Pacific Series”) and The Canadian Small Company Series (the “Canadian Series”) (each an “Underlying Fund” and together, the “Underlying Funds”), each of which is a series of The DFA Investment Trust Company. Periodically, Dimensional Fund Advisors LP (the “Sub-Adviser”) will review the allocations for the DFA Portfolio in each Underlying Fund and may adjust allocations to the Underlying Funds or may add or remove Underlying Funds in the DFA Portfolio without notice to shareholders.

To achieve the DFA Portfolio’s and the Underlying Funds’ investment objectives, the Sub-Adviser implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the DFA Portfolio’s and the Underlying Funds’ designs emphasize long-term drivers of expected returns identified by the Sub-Adviser’s research, while balancing risk through broad diversification across companies and sectors. The Sub-Adviser’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs. 

The DFA Portfolio is designed to provide investors with access to securities portfolios consisting of a broad range of equity securities of primarily small Canadian, Japanese, United Kingdom, Continental European and Asia Pacific companies. The DFA Portfolio also may have some exposure to small capitalization equity securities associated with other countries or regions. Each Underlying Fund invests in small companies using a market capitalization weighted approach in each country or region designated by the Sub-Adviser as an approved market for investment. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of an Underlying Fund than companies with relatively lower market capitalizations. The DFA Portfolio and Underlying Funds may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the countries and/or regions in which the DFA Portfolio and/or Underlying Funds are authorized to invest. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Sub-Adviser may consider additional factors such as price-to-cash flow or price-to-earnings ratios. An equity issuer is considered to have high profitability primarily because it has high earnings or profits from operations in relation to its book value or assets. In assessing profitability, the Sub-Adviser will consider additional information such as a company’s growth in profits. The criteria the Sub-Adviser uses for assessing relative price and profitability are subject to change from time to time. As a non-fundamental policy, under normal circumstances, the Fund, through its investments in the DFA Portfolio and, indirectly, the Underlying Funds, will invest at least 80% of its net assets in securities of small companies.

The Sub-Adviser defines “small companies” to mean companies whose market capitalization is below $18.5 billion in developed ex-U.S. markets. This threshold is as of August 31, 2026, and will fluctuate due to market conditions. For purposes of determining compliance with this policy, the Fund will count the entire value of its investment in the DFA Portfolio, without looking through to the DFA Portfolio’s underlying investments, unless the Fund knows that the DFA Portfolio is not investing in accordance with its investment focus.

The Sub-Adviser may also increase or reduce the DFA Portfolio’s and/or Underlying Funds’ exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Sub-Adviser considers ratios such as recent changes in assets divided by total assets. The criteria the Sub-Adviser uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Sub-Adviser seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

As of August 31, 2026, the DFA Portfolio invested its assets in the Underlying Funds within the following ranges (expressed as a percentage of the DFA Portfolio’s assets):

The allocation of the assets of the DFA Portfolio to be invested in the Underlying Funds will be determined by the Sub-Adviser on at least a semi-annual basis. The Underlying Funds invest primarily in countries that the Sub-Adviser views as developed market countries. Each Underlying Fund may lend its portfolio securities to generate additional income.

The DFA Portfolio and the Underlying Funds are advised by the Sub-Adviser. For as long as the Fund invests substantially all of its assets in the DFA Portfolio, the Sub-Adviser will not receive any sub-advisory fee from the Fund for its sub-advisory services. The Sub-Adviser receives an investment management fee from the DFA Portfolio for the services the Sub-Adviser provides to the DFA Portfolio. The Sub-Adviser also receives investment management fees for providing investment management services to the Underlying Funds. The Sub-Adviser has agreed to this fee arrangement in order to prevent duplication of advisory fees to the Sub-Adviser.

The Fund may withdraw its investment in the DFA Portfolio at any time if the Fund’s Board of Trustees determines that it is in the best interest of the Fund and its shareholders to do so. If this happens, the Fund’s assets either will be invested in another mutual fund or will be invested directly according to the investment policies and restrictions described in this Prospectus.

To achieve the Fund’s investment objective, Dimensional Fund Advisors LP (the “Sub-Adviser”) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. The Fund is designed to purchase readily marketable equity securities of companies whose principal activities include ownership, management, development, construction or sale of residential, commercial or industrial real estate. As a non-fundamental policy, under normal circumstances, at least 80% of the Fund’s net assets will be invested in securities of companies in the real estate industry. The Sub-Adviser defines “real estate industry” to include certain real estate investment trusts (“REITs”) and companies engaged in residential construction and firms, except partnerships, whose principal business is to develop commercial property. The Fund generally considers a company to be principally engaged in the real estate industry if the company (i) derives at least 50% of its revenue or profits from the ownership, management, development, construction or sale of residential, commercial, industrial or other real estate; (ii) has at least 50% of the value of its assets invested in residential, commercial, industrial or other real estate; or (iii) is organized as a REIT or REIT-like entity. REIT or REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests.

The Fund will make equity investments in securities listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser, using a market capitalization weighted approach. The Fund invests in companies of all sizes. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Fund than companies with relatively lower market capitalizations. The Sub-Adviser may adjust the representation in the Fund of an eligible company, or exclude a company, after considering such factors as free float, trading strategies, liquidity, price momentum, short-run reversals, and other factors that the Sub-Adviser determines to be appropriate.

The Fund will purchase shares of REITs. A REIT is not subject to federal income tax on net income and gains it distributes to shareholders if it complies with several requirements relating to its organization, ownership, assets and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gain) for each taxable year.

The Fund may lend its portfolio securities to generate additional income.
