The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. 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	1 Year	3 Years	5 Years	10 Years
TAX-MANAGED U.S. EQUITY PORTFOLIO | Tax-Managed U.S. Equity Portfolio | USD ($)	23	71	124	280

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years

PORTFOLIO TURNOVER

The Tax-Managed U.S. 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 Portfolio’s performance. During the most recent fiscal year, the Tax-Managed U.S. Equity Portfolio’s portfolio turnover rate was 8% of the average value of its investment portfolio.

Principal Investment Strategies

Dimensional Fund Advisors LP’s (the “Advisor”) tax management strategies for the Tax-Managed U.S. Equity Portfolio are designed to maximize the after tax value of a shareholder’s investment. Generally, the Advisor buys and sells securities for the Tax-Managed U.S. Equity 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. Equity Portfolio, using a market capitalization weighted approach, generally purchases a broad and diverse group of securities of U.S. 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. company, the greater its representation in the Tax-Managed U.S. Equity Portfolio. The Advisor may adjust the representation in the Tax-Managed U.S. Equity Portfolio of an eligible company, or exclude a company, after considering such factors as free float, momentum, trading strategies, liquidity, size, value, profitability, and other factors that the Advisor determines to be appropriate, given market conditions. 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. 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 criteria the Advisor uses for assessing value or profitability are subject to change from time to time.

As a non-fundamental policy, under normal circumstances, the Tax-Managed U.S. Equity Portfolio will invest at least 80% of its net assets in securities of U.S. companies. As of the date of this Prospectus, the Advisor considers for purchase by Tax-Managed U.S. Equity Portfolio securities of companies whose market capitalizations generally fall within the range of total market capitalization. Total market capitalization is based on the market capitalization of U.S. operating companies listed on the New York Stock Exchange (“NYSE”), NYSE American LLC, Nasdaq Global Market^®, Nasdaq Capital Market^®, or such other securities exchanges deemed appropriate by the Advisor.

The Tax-Managed U.S. Equity Portfolio 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 to use derivatives for purposes of speculation or leveraging investment returns.

The Tax-Managed U.S. Equity 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.

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, in turn, the Tax-Managed U.S. Equity 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.

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. Equity 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 to carry more risk than other types of investments. When the Tax-Managed U.S. Equity Portfolio uses derivatives, it 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 Tax-Managed U.S. Equity Portfolio may lose money and there may be a delay in recovering the loaned securities. The Tax-Managed U.S. 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.

Cyber Security Risk: The Tax-Managed U.S. Equity 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.
