The Portfolio seeks to achieve exposure to a broad portfolio of securities of U.S. and non-U.S. companies in the real estate industry, with a focus on real estate investment trusts (REITs) or companies that the Advisor considers to be REIT-like entities. The Portfolio invests in companies of all sizes. The Portfolio may pursue its investment objective by investing its assets in the DFA Real Estate Securities Portfolio, DFA International Real Estate Securities Portfolio (the Underlying Funds), and/or directly in securities of companies in the real estate industry. 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. The Portfolio and Underlying Funds generally consider a company to be principally engaged in the real estate industry if the company (i) derives at least 50% of its revenue or profits from the ownership, management, development, construction, or sale of residential, commercial, industrial, or other real estate; (ii) has at least 50% of the value of its assets invested in residential, commercial, industrial, or other real estate; or (iii) is organized as a REIT or REIT-like entity. REITs and REIT-like entities are types of real estate companies that pool investors funds for investment primarily in income producing real estate or real estate related loans or interests. The Portfolio and each Underlying Fund invest in companies principally engaged in the real estate industry in its designated market using a market capitalization weighted approach. A companys market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio and each Underlying Fund than companies with relatively lower market capitalizations. The Advisor may adjust the representation in the Portfolio or the Underlying Funds of an eligible company, or exclude a company, after considering such factors as free float, price momentum, short-run reversals, trading strategies, liquidity, size, relative price, profitability, and other factors that the Advisor determines to be appropriate. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time. The Advisor also may limit or fix the Portfolios exposure to a particular country or issuer. As a non-fundamental policy, under normal circumstances, at least 80% of the DFA Global Real Estate Securities Portfolios net assets will be invested directly, or indirectly through its investment in the Underlying Funds, in securities of companies in the real estate industry. The Portfolio concentrates (i.e., invests more than 25% of its net assets) its investments in securities of companies in the real estate industry. In addition to, or in place of, investments in the Underlying Funds, the Portfolio also is permitted to invest directly in the same types of securities of companies in the real estate industry that are eligible investments for the Underlying Funds. The Portfolio and each Underlying Fund intend to purchase securities of companies associated with countries that the Advisor has identified as approved markets for investment for the Portfolio or Underlying Fund. The 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 Portfolio, directly or indirectly through its investment in the Underlying Funds, invests approximately 72% of its net assets in U.S. companies. This percentage will change due to market conditions. The DFA Global Real Estate Securities 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 Portfolios and an Underlying Funds investments may be denominated in foreign currencies, the Portfolio and Underlying Fund 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 DFA Global Real Estate Securities Portfolio and the 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 DFA Global Real Estate Securities Portfolio invests as of the date of this Prospectus (other than the Underlying Funds that are included elsewhere in the Portfolios Prospectus) is described in the Portfolios Prospectus in the section entitled ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES.
