Unisil Acquisition Corp., Santa Clara, Calif., hired MassMutual Retirement Services as bundled provider for its new 401(k) plan. Unisil, a manufacturer and marketer of silicon wafers, had filed for Chapter 11 and had been purchased out of bankruptcy by investment firm Dieling, Schreiber & Park. Unisil then became a new company and was required to start a new 401(k) plan, said Lisa Brown, Unisils director of human resources. The old $7 million 401(k) plan is being terminated by the trustee in bankruptcy, with the help of the old provider ReliaStar, she said. The new plan is expected to gain an estimated $6 million in assets once the old plans termination is complete and Unisil employees are allowed to roll over their assets into the new plan, Ms. Brown said. The new plan has 10 investment options either managed by MassMutual or by managers with MassMutuals alliance partners, she said. The options are a guaranteed fund and a core bond fund managed by MassMutual; an international equity fund subadvised by Harbour View Asset Management, a MassMutual affiliate; Blue Chip Growth run by Fidelity Investments; American Centurys Ultra Fund; a midcap growth fund managed by T. Rowe Price; and the four Destiny funds, MassMutuals lifestyle asset allocation options.
