To achieve its investment objective, the 2035 Target Date Portfolio allocates its assets to other mutual funds managed by Dimensional Fund Advisors LP (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 2035 (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 Portfolio’s 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., 2050 in the case of the Portfolio), at which time the Portfolio reaches its final static asset allocation. At the final landing point, the 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 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 Portfolio reaches the landing point, it is expected that the Advisor will recommend that the Board of Directors of the 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, 2024, the 2035 Target Date Portfolio has a target allocation of 50% to 70% to equity Underlying Funds and a target allocation of approximately 30% to 50% to fixed income Underlying Funds, which may include exposure through those fixed income Underlying Funds to long-term and intermediate-term U.S. Treasury Inflation-Protected Securities (“TIPS”). As of February 28, 2024, 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, money market funds, 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. The fixed income Underlying Funds primarily invest in securities that are considered investment grade at the time of purchase and which have a range of maturities, including ultra-short, short, intermediate, and long-term. Certain equity Underlying Funds purchase a broad and diverse group of securities of companies with a greater emphasis on smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the universe of securities such Underlying Funds invest in. A summary of the investment strategies and policies of the Underlying Funds in which the Portfolio invests as of the date of this Prospectus is described in the Portfolio’s Prospectus in the section entitled “ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES.”

The 2035 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. Certain Underlying Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities, to hedge foreign currency risks, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. Certain Underlying Funds also may enter into swaps to hedge against inflation risk associated with certain securities or 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 Fund’s 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 Portfolio and the Underlying Funds may lend their portfolio securities to generate additional income.
