PORTFOLIO TURNOVER

Principal Investment Strategies

When constructing the T.A. World ex U.S. Core Equity Portfolio’s investment portfolio, Dimensional Fund Advisors LP (the “Advisor”) intends to consider federal tax implications when making investment decisions with respect to individual securities to seek to provide a tax advantage. When consistent with the Portfolio’s investment policies, the Advisor will buy and sell securities for the Portfolio considering 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 Advisor purchases for the T.A. World ex U.S. Core Equity Portfolio a broad and diverse group of securities of non-U.S. companies in countries with developed and emerging markets with a greater emphasis on small capitalization and value companies as compared to their representation in the Non-U.S. Universe. For purposes of this Portfolio, the Advisor defines the Non-U.S. Universe as a market capitalization weighted portfolio of non-U.S. companies in developed and emerging markets that have been authorized for investment as approved markets by the Advisor’s Investment Committee. The Portfolio’s increased exposure to small capitalization and value companies may be achieved by decreasing the allocation of the T.A. World ex U.S. Core Equity Portfolio’s assets to the largest growth companies relative to their weight in the Non-U.S. Universe, 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. Securities are considered value stocks primarily because a company’s shares have a high book value in relation to their market value.

The T.A. World ex U.S. Core Equity Portfolio intends to purchase securities of companies associated with developed market and emerging market countries, which may include frontier markets (emerging market countries in an earlier stage of development), that the Advisor has designated as approved markets. As a non-fundamental policy, under normal circumstances, the T.A. World ex U.S. Core Equity Portfolio will invest at least 80% of its net assets in non-U.S. equity securities and/or investments that provide exposure to non-U.S. securities. The Advisor determines company size on a country or region specific basis and based primarily on market capitalization. The percentage allocation of the assets of the T.A. World ex U.S. Core Equity Portfolio to securities of the largest growth companies will generally be reduced from between 5% and 35% of their percentage weight in the Non-U.S. Universe. As of December 31, 2015, securities of the largest growth companies in the Non-U.S. Universe comprised approximately 14% of the Non-U.S. Universe and the Advisor allocated approximately 4% of the Portfolio to securities of the largest growth companies in the Non-U.S. Universe. The percentage by which the Portfolio’s allocation to securities of the largest growth companies is reduced will change due to market movements and other factors. The Advisor may also adjust the representation in the T.A. World ex U.S. Core Equity Portfolio of an eligible company, or exclude a company, after considering

T.A. World ex U.S. Core Equity Portfolio Summary Prospectus    3

such factors as free float, momentum, trading strategies, liquidity management, 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 T.A. World ex U.S. Core Equity Portfolio may use derivatives, such as futures contracts and options on futures contracts for foreign or 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 T.A. World ex U.S. Core 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 T.A. World ex U.S. Core 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.

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.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar). The T.A. World ex U.S. Core Equity Portfolio does not hedge foreign currency risk.

Emerging Markets Risk: Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than

those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Tax Advantage Strategy Risk: An investment strategy that considers the tax implications of investment decisions may alter the construction of the T.A. World ex U.S. Core Equity Portfolio and affect portfolio holdings, when compared to those of non-tax managed mutual funds. The Advisor anticipates that performance of the Portfolio may deviate from that of non-tax managed mutual funds.

Derivatives Risk: Derivatives are instruments, such as futures and foreign exchange forward 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 T.A. World ex U.S. Core 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 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 T.A. World ex U.S. Core Equity 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.

Cyber Security Risk: The T.A. World ex U.S. Core 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.
