C000160528 Investment Objective and Strategy
Dimensional Retirement Income Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Dfa Investment Dimensions Group INC.
Investment objective
The investment objective of the Dimensional Retirement Income Fund (the “Retirement Income Portfolio”) is to provide total return consistent with the Portfolio’s asset allocation. Total return is composed of income and capital appreciation.
Principal investment strategy
The Retirement Income Portfolio is designed for an investor currently in retirement. To achieve its investment objective, the Retirement Income Portfolio allocates its assets to other mutual funds managed by the Advisor (i.e., the Underlying Funds) according to an asset allocation strategy designed for investors who have retired and are planning to withdraw the value of the investment in the Portfolio over many years. The asset allocation strategy for the Retirement Income Portfolio reflects the need for reduced equity risk and lower volatility of the inflation-adjusted income the Portfolio may be able to support during an investors retirement. As of February 28, 2018, the Retirement Income Portfolio has a target allocation of 15% to 25% to equity Underlying Funds and a target allocation of approximately 75% to 85% to fixed income Underlying Funds, including exposure through those fixed income Underlying Funds to U.S.
treasury inflation-protected securities (TIPS). The Retirement Income Portfolio may invest in: (1) domestic equity Underlying Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies; (2) international equity Underlying Funds that purchase a broad and diverse portfolio of securities of companies in developed and emerging markets; and (3) fixed income Underlying Funds that may purchase U.S. and foreign debt securities such as obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, long-, intermediate- and short-term TIPS, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic and foreign issuers denominated in U.S. dollars but not trading in the United States, obligations of supranational organizations, and inflation-protected securities.
Information about the Underlying Funds in which the Retirement Income Portfolio may invest is described in the Portfolios Prospectus in the section entitled ADDITIONAL INFORMATION ABOUT INVESTMENT OBJECTIVES AND POLICIES . The Retirement Income Portfolio and each Underlying Fund may purchase or sell futures contracts and options on futures contracts, to adjust market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. The Portfolio and Underlying Funds do 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. Certain Underlying Funds use foreign currency forward contracts to hedge foreign currency risks, hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.
Certain Underlying Funds also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Underlying Funds total return. Also, the Retirement Income Portfolio and the Underlying Funds may lend their portfolio securities to generate additional income.
