St. Louis County Retirement Plans, Clayton, Mo., is conducting a shortlist search for a manager to run $40 million in active domestic large-cap core equities, said Kirk McCarley, personnel director. The new firm could replace Independence Investment, which is on watch for performance of a similar portfolio, Mr. McCarley said. Independence can rebid. Trustees at the $337 million pension plan will interview finalists at their June 24 board meeting; those firms have not been chosen, he said. A selection could be made that day. Summit Strategies is assisting. Officials at Independence officials declined to comment.
