Your election to receive reports in paper will apply to all DFA Funds held directly or to all funds held through your financial intermediary.

PORTFOLIO TURNOVER

A mutual fund generally 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 mutual fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the International High Relative Profitability Portfolio’s portfolio turnover rate was 9% of the average value of its investment portfolio.

Principal Investment Strategies

The International High Relative Profitability Portfolio purchases securities of large non-U.S. companies that the Advisor determines to have high profitability relative to other large cap companies in the same country or region, at the time of purchase. 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 Advisor may also adjust the representation in the Portfolio of an eligible company, or exclude a company, after considering such factors as market capitalization, free float, size, value, profitability, momentum, trading strategies, liquidity management, and other factors that the Advisor determines to be appropriate. 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. The criteria the Advisor uses for assessing value or profitability are subject to change from time to time. The Advisor may also adjust the representation in the Portfolio of an eligible company, or exclude a company, that the Advisor believes to be negatively impacted by environmental, social or governance factors (including accounting practices and shareholder rights) to a greater degree relative to other issuers.

The International High Relative Profitability Portfolio intends to purchase securities of large non-U.S. companies associated with developed market countries that the Advisor has designated as approved markets. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in securities of companies in the particular non-U.S. markets in which the Portfolio invests. The Advisor determines the minimum market capitalization of a large company with respect to each country or region in which the Portfolio invests. Based on market capitalization data as of December 31, 2019, the market capitalization of a large company in any country or region in which the Portfolio invests would be $1,822 million or above. This threshold will change due to market conditions.

The International High Relative Profitability Portfolio may gain exposure to companies in an approved market by purchasing equity securities in the form of depositary receipts or foreign listings, which may be listed or traded outside the issuer’s domicile country. The Portfolio also may purchase or sell futures contracts

International High Relative Profitability Portfolio Summary Prospectus    3

and options on futures contracts for foreign or 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 Portfolio may invest in ETFs and similarly structured pooled investments for the purpose of gaining exposure to the equity markets while maintaining liquidity.

The International High Relative Profitability 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.

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 International High Relative Profitability Portfolio does not hedge foreign currency risk.

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 International High Relative Profitability 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.

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

Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, 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 International High Relative Profitability 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, settlement,

liquidity, interest rate, market, credit and management risks, as well as 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 International High Relative Profitability Portfolio may lose money and there may be a delay in recovering the loaned securities. The 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.

Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside the Advisor’s control, including instances at third parties. The Portfolio and the Advisor seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Cyber Security Risk: The International High Relative Profitability 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.
