Strategy. The DFA LTIP Portfolio seeks its investment objective by generally investing in a universe of long-term fixed income securities structured to provide protection against inflation. The Portfolio may invest in inflation-protected securities issued by the U.S. Government and its agencies and instrumentalities. The Portfolio also may invest in inflation-protected securities of other investment grade issuers (e.g., rated AAA to BBB- by S&P Global Ratings (S&P) or Fitch Ratings Ltd. (Fitch) or Aaa to Baa3 by Moodys Ratings (Moodys)) including foreign governments and U.S. and non-U.S. corporations.

The Portfolio may invest in inflation-protected securities issued by the U.S. Government and its agencies and instrumentalities. The Portfolio also may invest in inflation-protected securities of other investment grade issuers (e.g., rated AAA to BBB- by S&P Global Ratings (S&P) or Fitch Ratings Ltd. (Fitch) or Aaa to Baa3 by Moodys Ratings (Moodys)) including foreign governments and U.S. and non-U.S. corporations. The fixed income securities in which the Portfolio invests are considered investment grade at the time of purchase. Inflation-protected securities (also known as inflation-indexed securities) are securities whose principal and/or interest payments are adjusted for inflation, unlike conventional debt securities that make fixed principal and interest payments. Inflation-protected securities include Treasury Inflation-Protected Securities (TIPS), which are securities issued by the U.S. Treasury. The principal value of TIPS is adjusted for inflation (payable at maturity) and the semi-annual interest payments by TIPS equal a fixed percentage of the inflation-adjusted principal amount. These inflation adjustments are based upon the Consumer Price Index for Urban Consumers (CPI-U). The original principal value of TIPS is guaranteed. At maturity, TIPS are redeemed at the greater of their inflation-adjusted principal or par amount at original issue. Other types of inflation-protected securities may use other methods to adjust for inflation and other measures of inflation. In addition, inflation-protected securities issued by entities other than the U.S. Treasury may not provide a guarantee of principal value at maturity. Generally, the DFA LTIP Portfolio will purchase long-term fixed income securities with maturities greater than ten years from the date of settlement, although at times, the Portfolio may purchase securities with shorter maturities. The Portfolio ordinarily will have a weighted average effective maturity, based upon market values, of greater than ten years. The effective maturity adjusts the stated final maturity of a fixed income security for an actual or expected event such as a call, put, tender, mandatory early redemption, pre-refunding, coupon or interest rate reset, or other similar event. The DFA LTIP Portfolio also may invest in securities issued by the U.S. Government and its agencies and instrumentalities and other investment grade issuers that do not provide inflation protection while attempting to protect for inflation by engaging in swaps, futures or other derivatives to hedge against the inflation risk associated with such securities. The Portfolio may also invest in money market funds. Because many of the LTIP Portfolios investments may be denominated in foreign currencies, the Portfolio may enter into foreign currency forward contracts to attempt 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 purchase or sell futures contracts and options on futures contracts, 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. As a non-fundamental policy, under normal circumstances, at least 80% of the DFA LTIP Portfolios net assets will be invested in fixed income securities. The DFA LTIP Portfolio is authorized to invest more than 25% of its total assets in Treasury bonds, bills and notes and obligations of U.S. government agencies and instrumentalities. The Portfolio will not shift the maturity of its investments in anticipation of interest rate movements. The DFA LTIP Portfolio may lend its portfolio securities to generate additional income.
