Manchester (Conn.) Retirement Allowance Fund, with about $93 million in assets, is planning to search for a domestic large-cap value stock manager to replace Loomis Sayles, which was terminated recently for performance reasons, said Alan Desmarais, director of finance. The system has parked the $11 million that Loomis managed in a Russell 1000 value portfolio with State Street Global Advisors until it finds a replacement. The system is not ready to send out RFPs yet. It also terminated Furman Selz Capital Management, a domestic small-cap growth manager, for performance reasons. The system invested the $4 million portfolio run by Furman in five small-cap growth mutual funds. Tom Kolefas, vice president and counselor for Loomis Sayles, declined to comment on the termination. Furman Selz officials did not return phone calls for comment by press time.
