Generac Power Systems Inc., Waukesha, Wis., is conducting asset allocation studies of its two defined benefit plans. The studies are expected to be finished in July, when company officials will begin reviewing the 10 investment options offered by the companys two 401(k) plans, said Linda Kuklinski, treasury and risk manager. Plan officials are conducting the studies because of market volatility; they are not using a consultant. The defined benefit plans have $17 million in combined assets, and the 401(k) plans have a total of $10 million in assets, according to the Money Market Directory. U.S. Bank is bundled provider of the 401(k) plans.
