Portfolio Risks

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 Portfolio that owns them, to rise or fall.

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.

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 or cause losses if the market moves in a manner different from that anticipated by the Portfolio or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When the Portfolio uses derivatives, the Portfolio will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks, including commodity, counterparty, 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. 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. 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.

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.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar). The Portfolio seeks to hedge foreign currency exposure.

Foreign Government Debt Risk: The risk that: (a) the governmental entity that controls the repayment of government debt may not be willing or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as political considerations, the relative size of the governmental entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other national economic factors; (b) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole or in part.

Interest Rate Risk: Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to changes in interest rates.

Credit Risk: Credit risk is the risk that the issuer of a security, or the counterparty to an agreement or contract, including a derivative instrument, such as a credit default swap, may be unable or unwilling to meet its financial obligations. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength may affect a security’s value, and thus, impact the Portfolio’s performance. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest.

Call Risk: Call risk is the risk that during periods of falling interest rates, a bond issuer will call or repay a higher-yielding bond before its maturity date, forcing the Portfolio to reinvest in bonds with lower interest rates than the original obligations.

Liquidity Risk: Certain portfolio holdings, such as commodity-linked derivative instruments and swap agreements, may be difficult or impossible to sell at the time and the price that the Portfolio would like. The Portfolio may have to lower the price, sell other holdings instead, or forego an investment opportunity. Any of these could have a negative effect on management of the Portfolio or the Portfolio’s performance.

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.

Tax Risk: The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Portfolio from certain commodity-linked derivatives was treated as non-qualifying income, the Portfolio might fail to qualify as a regulated investment company and be subject to federal income tax at the Portfolio level. As a regulated investment company, the Portfolio must derive at least 90% of its gross income for each taxable year from sources treated as qualifying income under the Internal Revenue Code of 1986, as amended (the “Code”). The Portfolio has obtained a private letter ruling from the Internal Revenue Service confirming that the income the Portfolio derives from a form of commodity-linked note and the Subsidiary constitutes qualifying income under the Code. However, in September 2016 the Internal Revenue Service announced that it will no longer issue private letter rulings on questions relating to the treatment of a corporation as a regulated investment company that require a determination of whether a financial instrument or position is a security under section 2(a)(36) of the 1940 Act. In connection with this announcement, on September 29, 2016, the Internal Revenue Service proposed to revoke the portion of the ruling issued to the Portfolio regarding the treatment of commodity-linked notes held directly by the Portfolio retroactively to the date the ruling was issued (September 22, 2010). Despite the ruling, the Portfolio historically has not invested directly in commodity-linked notes. The Portfolio anticipates that the Internal Revenue Service will revoke the portion of its private letter ruling regarding the treatment of commodity-linked notes held directly by the Portfolio retroactively to the date the ruling was issued. As a result of the foregoing, the Portfolio may invest in commodity-linked notes only: (a) directly, generally only to the extent that it obtains an opinion of counsel confirming that income from such investments should be qualifying income because such commodity linked notes constitute securities under section 2(a)(36) of the 1940 Act or (b) indirectly, as the Portfolio traditionally has done, through the Subsidiary. Additionally, in September 2016, the IRS issued proposed regulations that would require the Subsidiary to distribute its “Subpart F” income (defined in Section 951 of the Code to include passive income such as income from commodity-linked derivatives) each year in order for the Portfolio to treat that income as qualifying income. If the Portfolio does not appropriately limit such investments or if such investments (or the income earned on such investments) were to be recharacterized for U.S. tax purposes, the Portfolio could fail to qualify as a regulated investment company. In this event, the Portfolio’s Board of Trustees may authorize a significant change in investment strategy or Portfolio liquidation. The Portfolio will notify shareholders in advance of any significant change in investment strategy or a liquidation of the Portfolio. In lieu of potential disqualification, the Portfolio is permitted to pay a tax for certain failures to satisfy the income requirement, which, in general, are limited to those due to reasonable cause and not willful neglect. The Portfolio also may incur transaction and other costs to comply with any new or additional guidance from the Internal Revenue Service. For more information, please see the “TAXATION OF THE PORTFOLIO AND ITS SHAREHOLDERS” section in the Portfolio’s Statement of Additional Information.

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.

Regulatory Risk: Governments, agencies, or other regulatory bodies may adopt or change laws or regulations that could adversely affect the issuer, the market value of the security, or the Portfolio’s performance.

Valuation Risk: The lack of an active trading market may make it difficult to obtain an accurate price for a security held by the Portfolio. Many commodity-linked derivative instruments are not actively traded.

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the Portfolio may lose money and there may be a delay in recovering the loaned securities. The Portfolio could also lose money if the Portfolio does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.

Cyber Security Risk: The Portfolio’s and its service providers’ use of internet, technology and information systems may expose the Portfolio to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the Portfolio and/or its service providers to suffer data corruption or lose operational functionality.
