SPTL seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the Bloomberg Barclays Long U.S. Treasury Index (the "Index"). The Bloomberg Barclays Long U.S. Treasury Index includes all publicly issued, U.S. Treasury securities that have a remaining maturity of 10 or more years, are rated investment grade, and have $250 million or more of outstanding face value. In addition, the securities must be denominated in U.S. dollars and must be fixed rate and non convertible. Excluded from the Long U.S. Treasury Index are certain special issues, such as flower bonds, TINs, state and local government series bonds, TIPS, and coupon issues that have been stripped from bonds included in the index.
