Portfolio Turnover

The U.S. Vector Equity 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. Vector Equity Portfolio's performance. During the most recent fiscal year, the U.S. Vector Equity Portfolio's portfolio turnover rate was 10% of the average value of its investment portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Dimensional Fund Advisors LP (the "Advisor") believes that equity investing should involve a long-term view and a systematic focus on sources of expected returns, not on stock picking or market timing. In constructing an investment portfolio, the Advisor identifies a broadly diversified universe of eligible securities with precisely-defined risk and return characteristics. It then places priority on efficiently managing portfolio turnover and keeping trading costs low. The Advisor does not intend to purchase or sell securities for the investment portfolio based on prospects for the economy, the securities markets or the individual issuers whose shares are eligible for purchase.

             The U.S. Vector Equity Portfolio purchases a broad and diverse group of common stocks of U.S. operating companies with a greater emphasis on small capitalization and value companies as compared to their representation in the U.S. Universe. The Advisor generally defines the U.S. Universe as a free float adjusted market capitalization weighted portfolio of U.S. operating companies listed on the New York Stock Exchange ("NYSE"), NYSE Alternext US LLC or Nasdaq Global Market^® or such other securities exchanges deemed appropriate by the Advisor. The Portfolio's increased exposure to small capitalization 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 or by avoiding purchases in that segment of the market, either of which would result in a greater weight allocation to small capitalization and value companies. An equity issuer is considered a growth company primarily because it has a low, non-negative book value in relation to its market capitalization. An equity issuer is considered a value company primarily because it has a high book value in relation to its market capitalization.

As a non-fundamental policy, under normal circumstances, the U.S. Vector Equity 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. Vector Equity Portfolio to securities of the largest U.S. growth companies as defined above will generally be reduced from between 5% and 50% of their percentage weight in the U.S. Universe. For example, as of December 31, 2011, securities of the largest U.S. growth companies comprised 32% of the U.S. Universe and the Advisor allocated approximately 2% of the U.S. Vector Equity Portfolio to securities of the largest U.S. growth companies. The percentage by which the Portfolio's allocation to securities of the largest U.S. growth companies is reduced will fluctuate with market movements and other factors. Additionally, the range by which the Portfolio's percentage allocation to the securities of the largest U.S. growth companies is reduced as compared to the U.S. Universe will change from time to time.

The U.S. Vector Equity Portfolio also may use derivatives, such as futures contracts and options on futures contracts for U.S. equity securities and indices, to gain market exposure on its uninvested cash pending investment in securities or to maintain liquidity to pay redemptions.

The U.S. Vector Equity 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. Vector Equity 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.

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 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. Vector Equity 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 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. Vector Equity Portfolio may lose money and there may be a delay in recovering the loaned securities. The U.S. Vector Equity 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.

PERFORMANCE

The bar chart and table immediately following illustrate the variability of the U.S. Vector Equity Portfolio's returns and are meant to provide some indication of the risks of investing in the Portfolio. The bar chart shows the changes in the U.S. Vector Equity Portfolio's performance from year to year. The table illustrates how annualized one year, five year and since inception returns, both before and after taxes, compare with those of a broad measure of market performance. The U.S. Vector Equity Portfolio's past performance (before and after taxes) is not an indication of future results. Updated performance information for the Portfolio can be obtained by visiting www.dimensional.com.

The after-tax returns presented in the table for the U.S. Vector Equity 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.
