The Portfolios portfolio securities may be of any maturity. The Adviser uses fundamental and other investment research techniques to determine what debt obligations to buy and sell. Fundamental techniques assess a securitys value based on factors such as an issuers financial profile, management, and business prospects, as applicable. The Portfolio seeks to achieve a return consisting of income earned on the Portfolios investments plus capital appreciation, if any. The Portfolio may invest in U.S. dollar denominated sovereign debt of foreign governments. The Portfolio utilizes derivatives primarily in the form of U.S. Treasury futures contracts in order to manage the Portfolios duration, or interest rate risk. The Portfolio may enter into derivatives contracts traded on exchanges or in the over the counter market. Show less
