Alliant Techsystems, Hopkins, Minn., is expected to begin an asset allocation study after it completes a manager review, which could lead to changes, said John Lotzer, director of investments for the $1 billion defined benefit plan. The plan’s last asset allocation study was in 1995. The current asset mix is 45% U.S. equities, 24% international equities, 30% domestic fixed income and 1% cash. The manager review is expected to be completed by May.
