To achieve the U.S. Large Cap Growth Portfolio’s investment objective, Dimensional Fund Advisors LP (the “Advisor”) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’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 U.S. Large Cap Growth Portfolio is designed to purchase a broad and diverse group of readily marketable securities of large U.S. companies that the Advisor determines to have high profitability and high relative prices compared to other U.S. large cap companies at the time of purchase. 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 Portfolio than companies with relatively lower market capitalizations. Securities are considered higher relative price (growth) stocks primarily because a company’s shares have a high price in relation to their book value (a “price to book ratio”) when compared with other U.S. large cap companies. The Advisor may overweight certain stocks, including smaller companies, lower relative price (value) stocks, and/or higher profitability stocks within the large-cap growth segment of the U.S. market. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. 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 Advisor uses for assessing relative price or profitability are subject to change from time to time.

As a non-fundamental policy, under normal circumstances, the U.S. Large Cap Growth Portfolio will invest at least 80% of its net assets in securities of large cap U.S. companies. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers large cap companies to be companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. 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 Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of December 31, 2023, the market capitalization of a large cap company would be $9,960 million or above. This threshold will change due to market conditions.

The Advisor may also increase or reduce the U.S. Large Cap Growth Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum and short-run reversals. In addition, the Advisor 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 U.S. Large Cap Growth Portfolio may purchase or sell futures contracts and options on futures contracts for U.S. equity securities and indices, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio.

The U.S. Large Cap Growth Portfolio may lend its portfolio securities to generate additional income.
