B.C. Zielger & Co., Milwaukee, will start an annual review of its $30 million 401(k)/profit-sharing plan later this month, said Scott Stevens, retirement director. Trustees will review the plan's 30 investment options, paying particular attention to three funds implicated in the recent mutual fund trading scandal, Mr. Stevens said; he would not identify them. The review will likely take two months. ExpertPlan is the record keeper. No consultant will be used.
