As further described below, the Funds design emphasizes long-term drivers of expected returns identified by the Sub-Advisers research, while balancing risk through broad diversification across companies and sectors. The Sub-Advisers 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-Advisers market capitalization guidelines described above, based on market capitalization data as of August 31, 2025 , the market capitalization of an eligible company would be approximately $5 .3 billion or above. This dollar amount will vary due to market conditions. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest 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 Funds portfolio. A companys 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 because it has high earnings or profits from operations in relation to its book value or assets. 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 Funds exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a companys price momentum, short-run reversals, and investment characteristics. In assessing a companys 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 companys 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. Show less
