(Fitch) or Aaa to Baa3 by Moodys Ratings (Moodys)). In addition, the Portfolio may 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, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Portfolio generally invests with an emphasis on debt securities rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moodys. The Portfolio will increase or decrease investment exposure to lower-rated investment grade securities (i.e., those rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moodys) depending on the expected credit premium. The Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. The Short-Term Extended Quality Portfolio primarily invests in securities that mature within five years from the date of settlement and maintains a weighted average effective maturity and a weighted average duration of three years or less. In making these purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the Advisor will focus on investment in the longer-term area, otherwise, the Portfolio will focus its investment in the shorter-term area of the eligible maturity range. 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 changes in interest rates. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities considered to be investment grade quality. 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 Short-Term Extended Quality Portfolios investments may include securities denominated in foreign currencies. The Portfolio intends to hedge foreign currency exposure to attempt to protect against uncertainty in the level of future foreign currency rates. The Portfolio may enter into foreign currency forward contracts to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. 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 Portfolios 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 Short-Term Extended Quality Portfolio may lend its portfolio securities to generate additional income. Show less
