The investment seeks total return consistent with the creditworthiness of U.S. Treasury securities. The fund invests primarily in zero-coupon U.S. Treasury securities. The advisor seeks to track the price behavior of a zero-coupon bond with the same term to maturity as the portfolio. To limit reinvestment risk, the advisor may adjusts the weighted average maturity so that, normally, at least 90% of the securities held mature within one year of the target maturity year. The fund will be liquidated at the end of 2025.
