PORTFOLIO TURNOVER

The DFA International Small Cap Value Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the DFA International Small Cap Value Portfolio’s performance. During the most recent fiscal year, the DFA International Small Cap Value Portfolio’s portfolio turnover rate was 21% of the average value of its investment portfolio.

Principal Investment Strategies

The DFA International Small Cap Value Portfolio, using a market capitalization weighted approach, purchases securities of small, non-U.S. companies in countries with developed markets that Dimensional Fund Advisors LP (the “Advisor”) determines to be value stocks at the time of purchase. A company’s market capitalization is the number of its shares outstanding times its price per share. In general, the higher the relative market capitalization of a small company within an eligible country, the greater its representation in the Portfolio. The Advisor may adjust the representation in the DFA International Small Cap Value Portfolio of an eligible company, or exclude a company, after considering such factors as free float, momentum, trading strategies, liquidity, value, profitability, and other factors that the Advisor determines to be appropriate, given market conditions. Securities are considered value stocks primarily because a company’s shares have a low price in relation to their book value. In assessing value, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. In assessing profitability, the Advisor may consider different ratios, such as that of earnings or profits from operations relative to book value or assets. The criteria the Advisor uses for assessing value or profitability are subject to change from time to time.

The DFA International Small Cap Value Portfolio intends to purchase securities of small value companies associated with developed market countries that the Advisor has designated as approved markets. As a non-fundamental policy, under normal circumstances, the DFA International Small Cap Value Portfolio will invest at least 80% of its net assets in securities of small companies in the particular markets in which it invests. The Advisor determines the maximum market capitalization of a small company with respect to each country in which the Portfolio invests. In the countries or regions authorized for investment, the Advisor first ranks eligible companies listed on selected exchanges based on the companies’ market capitalizations. The Advisor then determines the universe of eligible securities by defining the maximum market capitalization of a small company that may be purchased by the Portfolio with respect to each country or region. Based on market capitalization data as of December 31, 2017, for the DFA International Small Cap Value Portfolio, the highest maximum market capitalization of a small company in any country in which the DFA International Small Cap Value Portfolio invests would be $6,984 million. This threshold will vary by country or region. For example, based on market capitalization data as of December 31, 2017, the Advisor would consider a small company in Switzerland to have a market capitalization below $5,845 million, a small company in Norway to have a market capitalization below $1,593 million, and a small company in Japan to have a market capitalization below $2,399 million. This threshold will change due to market conditions.

The DFA International Small Cap Value 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 DFA International Small Cap Value Portfolio also may purchase or sell futures contracts and options on futures contracts for foreign and U.S. equity securities and indices, to adjust market exposure based on actual or expected cash inflows to or outflows from the Portfolio. The Portfolio does not intend to sell futures contracts to establish short positions in individual securities or to use derivatives for purposes of speculation or leveraging investment returns.

The DFA International Small Cap Value Portfolio may lend its portfolio securities to generate additional income.

Principal Risks

Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description of principal risks of investing in the Portfolio.

Equity Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and the Portfolio that owns them, to rise or fall. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

Small Company Risk: Securities of small companies are often less liquid than those of large companies and this could make it difficult to sell a small company security at a desired time or price. As a result, small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar). The DFA International Small Cap Value Portfolio does not hedge foreign currency risk.

Value Investment Risk: Value stocks may perform differently from the market as a whole and following a value-oriented investment strategy may cause the Portfolio to at times underperform equity funds that use other investment strategies.

Derivatives Risk: Derivatives are instruments, such as futures and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When the DFA International Small Cap Value Portfolio uses derivatives, the Portfolio will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Portfolio could lose more than the principal amount invested.

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the DFA International Small Cap Value Portfolio may lose money and there may be a delay in recovering the loaned securities. The DFA International Small Cap Value Portfolio could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.

Cyber Security Risk: The DFA International Small Cap Value Portfolio’s and its service providers’ use of internet, technology and information systems may expose the Portfolio to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the Portfolio and/or its service providers to suffer data corruption or lose operational functionality.
