Example

This Example is meant to help you compare the cost of investing in the Tax-Managed U.S. Small Cap Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - (USD $)	1 Year	3 Years	5 Years	10 Years

Portfolio Turnover

The Tax-Managed U.S. Small 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 Tax-Managed U.S. Small Cap Portfolio's performance. During the most recent fiscal year, the Tax-Managed U.S. Small Cap Portfolio's portfolio turnover rate was 22% 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 Advisor's tax management strategies for the Tax-Managed U.S. Small Cap Portfolio are designed to maximize the after tax value of a shareholder's investment. Generally, the Advisor buys and sells securities for the Portfolio with the goals of: (i) delaying and minimizing the realization of net capital gains (e.g., selling stocks with capital losses to offset gains, realized or anticipated); and (ii) maximizing the extent to which any realized net capital gains are long-term in nature (i.e., taxable at lower capital gains tax rates).

The Tax-Managed U.S. Small Cap Portfolio, using a market capitalization weighted approach, generally purchases a broad and diverse group of readily marketable common stocks of U.S. small 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. small cap company, the greater its representation in the Portfolio. The Advisor may modify market capitalization weights after considering such factors as free float, momentum, trading strategies, liquidity management and other factors that the Advisor determines to be appropriate, given market conditions.

As a non-fundamental policy, under normal circumstances, the Tax-Managed U.S. Small Cap Portfolio will invest at least 80% of its net assets in securities of small cap U.S. companies. As of the date of this Prospectus, for purposes of the Tax-Managed U.S. Small Cap Portfolio, the Advisor considers small cap companies to be companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th 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 Alternext US 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, 2011, the market capitalization of a small cap company was $2,444 million, or below. This dollar amount will change due to market conditions. As a non-fundamental policy, under normal circumstances, the U.S. Small Cap Portfolio will invest at least 80% of its net assets in securities of small cap U.S. companies.

The Tax-Managed U.S. Small Cap Portfolio 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 Tax-Managed U.S. Small 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 Tax-Managed U.S. Small 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.

Tax-Management Strategy Risk: The tax-management strategies may alter investment decisions and affect portfolio holdings, when compared to those of non-tax managed mutual funds. The Advisor anticipates that performance of the Tax-Managed U.S. Small Cap Portfolio may deviate from that of non-tax managed mutual funds.

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 Tax-Managed U.S. Small 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 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 Tax-Managed U.S. Small Cap 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.
