PORTFOLIO TURNOVER

The U.S. Social Core 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 Portfolio’s performance. During the most recent fiscal year, the U.S. Social Core Portfolio’s portfolio turnover rate was 16% of the average value of its investment portfolio.

Principal Investment Strategies

The U.S. Social Core Portfolio purchases a broad and diverse group of securities of U.S. companies with a greater emphasis on small capitalization and value companies as compared to their representation in the U.S. Universe, while excluding companies based on the Portfolio’s social issue screens. Dimensional Fund Advisors LP (the “Advisor”) generally defines the U.S. Universe as a market capitalization weighted portfolio of U.S. operating companies listed on the New York Stock Exchange (“NYSE”), NYSE MKT LLC, Nasdaq Global Market^®, Nasdaq Capital Market^®, or such other securities exchanges deemed appropriate by the Advisor. The Portfolio’s increased exposure to small and value companies may be achieved by decreasing the allocation of the Portfolio’s assets to the largest U.S. growth companies relative to their weight in the U.S. Universe. An equity issuer is considered a growth company primarily because it has a low book value, that is not negative, in relation to its market capitalization. Securities are considered to be value stocks primarily because a company’s shares have a high book value in relation to their market value.

As a non-fundamental policy, under normal circumstances, U.S. Social Core Portfolio will invest at least 80% of its net assets in equity securities of U.S. companies. The percentage allocation of the assets of the U.S. Social Core Portfolio to securities of the largest U.S. growth companies as defined above will generally be reduced from between 5% and 35% of their percentage weight in the U.S. Universe. For example, as of December 31, 2016, securities of the largest U.S. growth companies comprised 31% of the U.S. Universe and the Advisor allocated approximately 14% of the U.S. Social Core Portfolio to securities of the largest U.S. growth companies. The percentage by which the U.S. Social Core Portfolio’s allocation to securities of the largest U.S. growth companies is reduced will change due to market movements, results of social issue screens and other factors. The Advisor may adjust the representation in the U.S. Social Core Portfolio of an eligible company, or exclude a company, after considering such factors as free float, momentum, trading strategies, liquidity, profitability, and other factors that the Advisor determines to be appropriate, given market conditions. 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 U.S. Social Core Portfolio also may purchase or sell futures contracts and options on futures contracts for 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 use derivative for purposes of speculation or leveraging investment returns. The above-referenced investments are not subject to, though they may incorporate, the Portfolio’s social criteria.

The U.S. Social Core Portfolio may lend its portfolio securities to generate additional income.

The U.S. Social Core Portfolio seeks to purchase securities that are consistent with the Portfolio’s social issue screens, which are monitored by an independent third party. The Portfolio seeks to exclude from its investment portfolio those companies that are identified by the Portfolio’s social issue screens. The Portfolio’s social issue screens generally are designed to identify companies that derive 15% or more of their revenue from the following industries: Casinos and Gambling; Drug retail; Brewers; Distillers and Vintners; Tobacco; Health Care Equipment and Supplies; Health Care Distributors; Health Care Facilities; Health Care Services; Managed Health Care; Health Care Technology; Biotechnology; Life Sciences Tools and Services; Pharmaceuticals; and Adult Entertainment. The Portfolio may modify this list of social issue screens, at any time, without prior shareholder approval or notice.

Principal Risks

Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. 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 U.S. Social Core 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.

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.

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.

Social Investment Risk: The U.S. Social Core Portfolio’s social issue screens may limit the number of investment opportunities available to the Portfolio, and as a result, at times the Portfolio may produce different returns than funds that are not subject to such special investment conditions. For example, the Portfolio may decline to purchase certain securities when it is otherwise advantageous to do so, or the Portfolio may sell certain securities for social reasons when it is otherwise disadvantageous to do so.

Derivatives Risk: Derivatives are instruments, such as futures 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 U.S. Social Core 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 U.S. Social Core Portfolio may lose money and there may be a delay in recovering the loaned securities. The U.S. Social Core 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 U.S. Social Core 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.
