Portfolio Turnover

The U.S. Micro Cap 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 U.S. Micro Cap Portfolio’s performance. During the most recent fiscal year, the U.S. Micro Cap Portfolio’s portfolio turnover rate was 12% of the average value of its investment portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The U.S. Micro Cap Portfolio, using a market capitalization weighted approach, purchases a broad and diverse group of the securities of U.S. micro cap companies. 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 the U.S. micro cap company, the greater its representation in the Portfolio. Dimensional Fund Advisors LP (the “Advisor”) may modify market capitalization weights and even exclude companies after considering such factors as free float, momentum, trading strategies, liquidity management, and profitability, as well as 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.

As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in securities of U.S. micro cap companies. As of the date of this Prospectus, for the purposes of the U.S. Micro Cap Portfolio, the Advisor considers micro cap companies to be companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on the New York Stock Exchange (“NYSE”), NYSE MKT LLC, Nasdaq Global Market^® or such other securities exchanges deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, as of December 31, 2014, the market capitalization of a micro cap company was $1,961 million or below. This dollar amount will change due to market conditions. When implementing its strategy, the U.S. Micro Cap Portfolio will, as of the date of this Prospectus, generally purchase securities of companies that are in the lowest 4% of total market capitalization but may also purchase securities of companies above this range that are considered micro cap companies under the Advisor’s market capitalization guidelines.

The U.S. Micro Cap Portfolio may use derivatives, such as 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 use derivatives for purposes of speculation or leveraging investment returns.

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

PRINCIPAL RISKS

Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer-specific events will cause the value of securities, and the U.S. Micro Cap Portfolio that owns them, to rise or fall. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

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.

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 more speculative than other types of investments. When the U.S. Micro Cap Portfolio uses derivatives, the Portfolio will be directly exposed to the risks of that derivative. 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. Micro Cap Portfolio may lose money and there may be a delay in recovering the loaned securities. The U.S. Micro Cap 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. Micro Cap 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.

The after-tax returns presented in the table for the U.S. Micro Cap Portfolio are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown in the table. In addition, the after-tax returns shown are not relevant to investors who hold shares of the Portfolio through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. A negative pre-tax total return translates into a higher after-tax return because this calculation assumes that an investor received a tax deduction for the loss incurred on the sale.
