H.E. Butt Grocery Co., San Antonio, is increasing its 401(k) plan's allocation to market-neutral hedge fund of funds to $43.5 million, from $29.5 million, and the $950 million plan might hire two or three managers to absorb the additional money, said Thomas Witt, director, savings and retirement plan. The hedge fund of funds allocation is one of the components used in the plan's three asset allocation options, which have a combined $760 million in plan assets. The General Fund, the Conservative Balanced and the Aggressive Balanced Funds all use the same asset classes and managers through unitized asset class pools. The asset class weightings in the conservative and aggressive funds are adjusted to match each fund's risk profile. The HEB 401(k) plan offers six investment options, none of them mutual funds. The other three options are an S&P 500 index fund, a passive intermediate-duration bond fund and a money market fund, all managed by State Street Global Advisors.
