The World Core Equity Portfolio is a “fund of funds,” which means that the Portfolio generally allocates its assets among other mutual funds managed by Dimensional Fund Advisors LP (the “Advisor”) although it also has the ability to invest directly in securities. To achieve the Portfolio’s and the Underlying Funds’ investment objectives, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s and the Underlying Funds’ designs emphasize long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies, sectors, and countries. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The World Core Equity Portfolio is designed to provide exposure to a broad portfolio of equity securities of both U.S. companies and non-U.S. companies associated with countries with developed and emerging markets, which may include frontier markets (emerging markets in an earlier stage of development), by primarily purchasing shares of U.S. Core Equity 1 Portfolio, International Core Equity 2 Portfolio and Emerging Markets Core Equity 2 Portfolio (the “Underlying Funds”). The Underlying Funds may have a modest to meaningful emphasis on securities of smaller, lower relative price, and higher profitability companies. The Portfolio may have exposure to companies in all the market capitalization ranges.

The World Core Equity Portfolio typically allocates its investments among the following Underlying Funds: U.S. Core Equity 1 Portfolio; International Core Equity 2 Portfolio; and Emerging Markets Core Equity 2 Portfolio. Periodically, the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations to the Underlying Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.

As a non-fundamental policy, under normal circumstances, at least 80% of the World Core Equity Portfolio’s net assets will be invested directly, or indirectly through its investment in the Underlying Funds, in equity securities. The World Core Equity Portfolio, directly or indirectly through its investment in the Underlying Funds, intends to invest its assets to gain exposure to at least three different countries, including the United States. As of the date of the Prospectus, the World Core Equity Portfolio, directly or indirectly through its investment in the Underlying Funds, invests approximately 61% of its net assets in U.S. companies. This percentage will change due to market conditions.

The Advisor may also increase or reduce the World Core Equity Portfolio’s and/or Underlying Funds’ exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The World Core Equity Portfolio and each Underlying Fund may purchase or sell futures contracts and options on futures contracts for equity securities and indices to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. Because many of the Portfolio’s and certain Underlying Funds’ investments may be denominated in foreign currencies, the Portfolio and certain Underlying Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer cash balances from one currency to another currency. The Portfolio and each Underlying Fund may invest in exchange-traded funds (“ETFs”) for the purposes of gaining exposure to the equity markets, while maintaining liquidity. In addition to money market instruments and other short-term investments, the Portfolio and each Underlying Fund may invest in affiliated and unaffiliated registered and unregistered money market funds. The Portfolio and Underlying Funds may invest in such money market funds and other short-term investments to manage cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in ETFs and money market funds may involve a duplication of certain fees and expenses.

The World Core Equity Portfolio and Underlying Funds may lend their portfolio securities to generate additional income.

A summary of the investment strategies and policies of the Underlying Funds in which the World Core Equity Portfolio invests as of the date of this Prospectus (other than the Underlying Funds that are included elsewhere in the Portfolio’s Prospectus) is described in the Portfolio’s Prospectus in the section entitled “ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES”.
