The credit quality of the securities purchased by the Portfolio will be that of the U.S. Government or its agencies. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in government securities that mature within five years from the date of settlement. It is the policy of the Portfolio that the maximum length of maturity of investments will not exceed five years from the date of settlement. In making these purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, Dimensional Fund Advisors LP (the Advisor) will focus investment in that longer-term area, otherwise, the portfolio will focus investment in the shorter-term area of the eligible maturity range. The Advisor expects that the Portfolios weighted average effective maturity and weighted average duration will be three years or less. 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. Duration is a measure of the sensitivity of a securitys price to changes in interest rates. The longer a securitys duration, the more sensitive it will be to interest rates. The Portfolio may also acquire repurchase agreements backed by U.S. government securities. The Portfolio may also invest in money market funds. 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 Short-Term Government 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. The Short-Term Government Portfolio may lend its portfolio securities to generate additional income. Show less
