Tetra Tech Inc., Pasadena, Calif., is reviewing responses to an RFI sent to bundled providers, including incumbent AMVESCAP, said Mel Fleeman, manager-retirement program. Officials for the $250 million 401(k)/profit-sharing plan like to periodically conduct a provider review as part of their due diligence and had not done so in a few years, Mr. Fleeman said. If AMVESCAP's services do not seem competitive with other firms being considered, officials might decide to proceed with an RFP. A decision is expected in about a month, he said. Capital Researching & Consulting is assisting. The plan now offers 16 investment options.
