The investment seeks total return. The fund invests in zero-coupon U.S. Treasury securities and U.S. Treasury bills, notes, and bonds that will mature in 2015, returning a dollar amount that approximates the return on a direct investment in zero-coupon securities for that year and that is predictable at the time of investment. The fund intends to maintain the duration of its holdings so that it falls within the year 2015. It will be liquidated at the end of 2015.
