C000160531 Investment Objective and Strategy
Dimensional 2055 Target Date 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 2055 Target Date Retirement Income Fund (the “2055 Target Date Portfolio”) is to provide total return consistent with the Portfolio’s current asset allocation. Total return is composed of income and capital appreciation.
Principal investment strategy
To achieve its investment objective, the 2055 Target Date 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 planning to retire in or within a few years of 2055 (the target date) and are planning to withdraw the value of the investment in the Portfolio over many years after the target date. Over time, the 2055 Target Date Portfolios allocation to the Underlying Funds is expected to change based on an asset allocation strategy that generally becomes more conservative (reducing its allocation to equity Underlying Funds and increasing its allocation to fixed income Underlying Funds) until reaching the landing point, which is 15 years after the target date (i.e., 2070 in the case of the 2055 Target Date Portfolio), at which time the Portfolio reaches its final static asset allocation.
At the final landing point, the 2055 Target Date Portfolio is expected to reach a final static asset allocation of 15% to 25% of its assets allocated to domestic and international equity Underlying Funds and 75% to 85% of its assets allocated to fixed income Underlying Funds. The asset allocation strategy for the 2055 Target Date Portfolio reflects the need for reduced equity risk and lower volatility of the inflation-adjusted income the Portfolio may be able to support in retirement as an investor gets closer to the target date. When the 2055 Target Date Portfolio reaches the landing point, it is expected that the Advisor will recommend that the Board of Directors of the 2055 Target Date Portfolio approve combining the Portfolio with the Dimensional Retirement Income Fund, another fund managed by the Advisor, which is expected to have approximately the same asset allocation as the Portfolio at that time.
As of February 28, 2018, the Portfolio has a target allocation of 75% to 97% to equity Underlying Funds and a target allocation of approximately 3% to 25% to fixed income Underlying Funds, including exposure through those fixed income Underlying Funds to long-term and intermediate-term U.S. treasury inflation-protected securities (TIPS). As of February 28, 2018, the 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 2055 Target Date Portfolio may invest is described in the Portfolios Prospectus in the section entitled ADDITIONAL INFORMATION ABOUT INVESTMENT OBJECTIVES AND POLICIES . The 2055 Target Date 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. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of the Portfolio between the date a foreign currency forward contract is entered into and the date it expires.
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. Certain Underlying Funds also may purchase or sell futures contracts and options on futures contracts, to hedge their interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment. Also, the 2055 Target Date Portfolio and the Underlying Funds may lend their portfolio securities to generate additional income.
