The Portfolio seeks to provide investors with exposure to a diversified portfolio of global equity securities. To achieve the Portfolios and the Underlying Funds investment objectives, Dimensional Fund Advisors LP (the Advisor) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolios and the Underlying Funds designs emphasize long-term drivers of expected returns identified by the Advisors research, while balancing risk through broad diversification across companies, sectors, and countries. The Advisors 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 Portfolio seeks to provide investors with exposure to a diversified portfolio of global equity securities. The Portfolio is designed to invest substantially all of its assets in the following Underlying Funds: VA U.S. Large Value Portfolio, VA U.S. Targeted Value Portfolio, U.S. Core Equity 1 Portfolio, VA International Value Portfolio, VA International Small Portfolio, International Core Equity 2 Portfolio, Emerging Markets Core Equity 2 Portfolio, DFA International Real Estate Securities Portfolio, DFA Real Estate Securities Portfolio (each a series of DFA Investment Dimensions Group Inc.) and U.S. Large Company Portfolio (a series of Dimensional Investment Group Inc.). Generally, the VA Equity Allocation Portfolio invests its assets in the Underlying Funds to gain exposure to equity securities with an allocation of approximately 55% to 75% of the Portfolios assets in U.S. equity securities, 0-15% in real estate securities, 10-35% in international developed markets equity securities, and 0-20% in emerging markets equity securities. 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, the VA Equity Allocation Portfolio, through its investments in the Underlying Funds, will invest at least 80% of its net assets in equity securities. Certain Underlying Funds may invest with a moderate to meaningful emphasis on securities of smaller, lower relative price, and higher profitability companies. The Portfolio may have exposure to companies in all market capitalization ranges. The Portfolio and each Underlying Fund may invest in affiliated and unaffiliated registered and unregistered money market funds to manage its cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in money market funds may involve a duplication of certain fees and expenses. The Advisor may also increase or reduce the VA Equity Allocation Portfolios and/or Underlying Funds exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a companys price momentum, short-run reversals, and investment characteristics. In assessing a companys investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a companys 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 VA Equity Allocation Portfolio and each Underlying Fund may gain exposure to companies associated with approved markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuers domicile country. The Portfolio and each Underlying Fund may use derivatives, such as futures contracts and options on futures contracts for equity securities and indices of its approved markets or other equity market securities or indices, including those of the United States, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. 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 balances from one currency to another. The VA Equity Allocation Portfolio and Underlying Funds may lend their portfolio securities to generate additional income. Certain of the Underlying Funds are available for investment only by insurance company separate accounts that fund variable life and variable annuity contracts.
