To achieve the International Vector Equity 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 International Vector Equity Portfolio is designed to purchase a broad and diverse group of equity securities of non-U.S. companies in developed markets. The Portfolio invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation

in the International Universe. For purposes of this Portfolio, the Advisor defines the International Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the International Universe it represents) of non-U.S. companies in developed markets that have been authorized for investment by the Advisor’s Investment Committee. The Portfolio’s increased exposure to smaller capitalization, lower relative price, and higher profitability companies may be achieved by decreasing the allocation of the Portfolio’s assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the International Universe or by avoiding purchases in that segment of the market. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. 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 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 and profitability are subject to change from time to time.

The Advisor determines company size on a country or region specific basis and based primarily on market capitalization. The Advisor will also establish a minimum market capitalization that a company must meet in order to be considered for purchase, which minimum will change due to market conditions.

The International Vector Equity Portfolio intends to purchase securities of companies associated with developed market countries that the Advisor has designated as approved markets for investment. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in equity securities. The percentage allocation of the assets of the Portfolio to securities of the largest high relative price companies will generally be reduced by between 5% and 50% of their percentage weight in the International Universe. For example, as of December 31, 2023, securities of the largest high relative price companies in the International Universe comprised approximately 16% of the International Universe and the Advisor allocated approximately less than 2% of the Portfolio to securities of the largest high relative price companies in the International Universe. The percentage by which the Portfolio’s allocation to securities of the largest high relative price companies is reduced, as compared to their representation in the International Universe, will change due to market movements and other factors.

The Advisor may also increase or reduce the International Vector Equity Portfolio’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 Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. 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 International Vector Equity Portfolio may gain exposure to companies associated with approved markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer’s domicile country. The Portfolio may purchase or sell futures contracts and options on futures contracts for foreign or 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. Because many of the Portfolio’s investments may be denominated in foreign currencies, the Portfolio may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer cash balances from one currency to another currency.

The International Vector Equity Portfolio may lend its portfolio securities to generate additional income.
