The DFA Commodity Strategy Portfolio seeks to achieve its investment objective by generally investing in a universe of allowable commodity-linked derivative instruments and fixed income investment opportunities. The Portfolio gains exposure to commodities markets by investing in derivative instruments, such as structured notes whose principal and/or coupon payments are linked to commodities or commodity indices, in swap agreements, and/or in other commodity-linked instruments (such as futures contracts on individual commodities or commodity indices). The Portfolio may invest up to 25% of its total assets in Dimensional Cayman Commodity Fund I Ltd. (the “Subsidiary”), a wholly-owned subsidiary of the Portfolio formed in the Cayman Islands, which has the same investment objective as the Portfolio and has a strategy of investing in derivative instruments, such as commodity-linked swap agreements and other commodity-linked instruments, futures contracts on individual commodities or

commodity indices, and options on these instruments. The Portfolio, directly and/or through its investment in the Subsidiary, expects to use such derivatives extensively as part of its investment strategy.

The DFA Commodity Strategy Portfolio will invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers having investment grade ratings (e.g., rated AAA to BBB- by S&P Global Ratings (“S&P”) or Fitch Ratings Ltd. (“Fitch”) or Aaa to Baa3 by Moody’s Investors Service, Inc. (“Moody’s”)), securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. Dimensional Fund Advisors LP (the “Advisor”) expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. The fixed income securities in which the Portfolio invests are considered investment grade at the time of purchase. In addition, the Portfolio is authorized to invest more than 25% of its total assets in U.S. Treasury bonds, bills and notes, and obligations of federal agencies and instrumentalities.

The DFA Commodity Strategy Portfolio’s fixed income securities primarily will mature within five years from the date of settlement, and the Portfolio maintains a weighted average duration of three years or less. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. Similarly, a portfolio with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the Advisor will focus investment in the longer-term area, otherwise, the Portfolio will focus investment in the shorter-term area of the eligible maturity range.

The DFA Commodity Strategy Portfolio’s investments may include foreign securities denominated in foreign currencies. The Portfolio intends to hedge foreign currency exposure to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio may hedge such currency exposure by entering into foreign currency forward contracts. The Portfolio 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 Portfolio’s expected total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its currency exposure or to hedge its interest rate exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Portfolio.

The DFA Commodity Strategy Portfolio may lend its portfolio securities to generate additional income.
