The Commodity Strategy Portfolio is a no-load mutual fund designed to seek total return consisting of capital appreciation and current income. The Portfolio invests in a universe of allowable commodity-linked derivative instruments and fixed income investments. The Portfolio gains exposure to commodities markets by investing in derivative instruments such as structured notes whose principal or coupon payments are linked to commodities or commodity indices, swap agreements, and other commodity-linked instruments. The Portfolio may invest up to 25% of its total assets in a wholly-owned subsidiary that has the same investment objective as the Portfolio and has a strategy of investing in derivative instruments. The Portfolio will pursue the fixed income portion of its strategy by investing in a universe of US and foreign investment grade fixed income securities (rated AAA to BBB- by Standard & Poor's Rating Group or Fitch Ratings Ltd. or Aaa to Baa3 by Moody's Investors Service, Inc.). The Portfolio invests in obligations issued or guaranteed by the US and foreign governments, their agencies and instrumentalities; bank obligations; commercial paper; repurchase agreements; obligations of other domestic and foreign issuers having investment grade ratings; securities of domestic or foreign issuers denominated in US dollars but not trading in the US; and obligations of supranational organizations. Currently, most investments are made in developed countries, but other countries may be added in the future. The Portfolio seeks to hedge foreign currency exposure. The Portfolio's fixed income securities primarily will mature within five years from the date of settlement and the Portfolio maintains an average portfolio duration of three years or less. This Portfolio is non-diversified, which means it may invest in fewer issuers than a diversified fund.

Market Risk Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer-specific events will cause the value of securities, and the funds that own them, to rise or fall. Because the value of your investment in a fund will fluctuate, there is a risk that you will lose money.
Non-Diversification Risk The risk that the fund may be more volatile than a diversified fund because it invests its assets in a smaller number of issuers. The gains or losses on a single security may, therefore, have a greater impact on the fund's net asset value.
Derivatives Risk Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. While hedging can reduce or eliminate losses, it also can reduce or eliminate gains. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. When the Portfolio uses derivatives, the Portfolio will be directly exposed to the risks of those derivatives. Derivative securities are subject to a number of risks, including commodity, correlation, interest rate, liquidity, market, credit and management risks, and the risk of improper valuation. The Portfolio also may use derivatives for leverage. The Portfolio's use of derivatives, particularly commodity-linked derivatives, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate, or index, and the Portfolio could lose more than the principal amount invested. For example, potential losses from commodity-linked notes or swap agreements can be unlimited. Additional risks are associated with the use of credit default swaps, including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Portfolio will engage in these transactions to reduce exposure to other risks when that would be beneficial.
Commodity Risk The value of commodity-linked derivative instruments may be affected by changes in overall market movements,
commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods,
weather, livestock disease, embargoes, tariffs, and international economic, political, and regulatory developments.
Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility
for greater loss (including the likelihood of greater volatility of the Portfolio's net asset value), and there can be no assurance that the
Portfolio's use of leverage will be successful.
Focus Risk The Portfolio may be exposed, from time to time, to the performance of a small number of commodity sectors (e.g.,
energy, metals or agricultural), which may represent a large portion of the Portfolio. As a result, the Portfolio may be subject to greater
volatility than if the Portfolio were more broadly diversified among commodity sectors.
Subsidiary Risk By investing in the Subsidiary, the Portfolio is indirectly exposed to the risks associated with the Subsidiary's investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Portfolio and are subject to the same risks that apply to similar investments if held directly by the Portfolio. These risks are described elsewhere in this Prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved.
The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the "1940 Act"), and, unless otherwise noted in this Prospectus, is not subject to all of the investor protections of the 1940 Act. However, the Portfolio wholly owns and controls the Subsidiary, and the Portfolio and the Subsidiary are both managed by the Advisor, making it unlikely that the Subsidiary will take action contrary to the interests of the Portfolio and its shareholders. The Board of Directors of DFA Investment Dimensions Group Inc. (the "Fund") has oversight responsibility for the investment activities of the Portfolio, including its investment in the Subsidiary, and the Portfolio's role as the sole shareholder of the Subsidiary. The Subsidiary will be subject to investment restrictions and limitations and compliance policies and procedures substantially similar to those imposed on the Portfolio by the 1940 Act.
Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Portfolio and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Portfolio. For example, the Cayman Islands currently do not impose any income, corporate, or capital gains tax, estate duty, inheritance tax, gift tax, or withholding tax on the Subsidiary. If Cayman Islands law changes, such that the Subsidiary must pay Cayman Islands taxes, Portfolio shareholders likely would suffer decreased investment returns.
Leveraging Risk Certain transactions that the Portfolio may enter into may give rise to a form of leverage. Such transactions may include, among others, structured notes, swap agreements, futures contracts, and loans of portfolio securities. The use of leverage may cause the Portfolio to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Leverage may cause the Portfolio to be more volatile than if the Portfolio had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Portfolio's portfolio securities.
