Trans World Airlines, Kansas City, Mo., hired Smith Henderson and Associates as a consultant for its $180 million 401(k)/(a) plan for non-contract workers, one of TWAs four 401(k) plans. Smith Henderson will review the current plan design and the investment policy and options, and suggest changes in a couple of months, said Larry Cleveland, TWA director-benefits. Some of the 10 options in the quasi-bundled plan, now administered by American Century, have not been performing as well as expected in a booming stock market and the company wants to replace those funds with better performers with low expense ratios, he said. American Century manages most of the investment options in the plan. The quasi-bundled plan format will likely be retained after the review, Mr. Cleveland said. The 401(k) plan has been without a consultant since last fall, when the previous consultant, which Mr. Cleveland declined to identify, was terminated. SHA will conduct any manager searches resulting from the plan review and will provide ongoing performance monitoring of plan options.
