Limited Inc., Columbus, Ohio, has moved to a bundled environment for its $430 million 401(k) plan, hiring American Express Retirement Services to provide investment management services, daily record keeping, trust services and employee education. The plan also has expanded its investment options to 13 funds including a self-directed brokerage account, from six, said Tim Meyer, media relations coordinator for The Limited. The new investment options offered through American Express and its alliance partners are three American Express Horizon funds, Janus Overseas, American Century Growth and Income, AXP Selective fund and a balanced fund. We wanted a bundled provider and felt American Express was the best choice because of the investment options, participant cost, technology and participant services, Mr. Meyer said. Watson Wyatt Worldwide had been the plans administrator; Chase Manhattan Bank, the trustee; and the Vanguard Group, the investment provider.
