Paper Converting Machine Co., Green Bay, Wis., is searching for a consultant to review the options in its $100 million PCMC Retirement Savings 401(k) plan, said Dale Barbiaux, corporate secretary and tax director. He said the plan wants an outside opinion before adding new options to the 11 currently offered. Previous consultant Putnam remains as record keeper, he said. The plan is self-administered and trusteed. The search is expected to take three months.
