Natick (Mass.) Contributory Retirement System is searching for an active domestic large-cap value equities manager to run $14 million. Kathleen Bacon, director of the $66 million plan, directed all questions to Kevin Leonard, the Segal Advisors consultant who is assisting. Mr. Leonard said the new firm will replace the current portfolio manager, which he declined to identify, because of personnel turnover and performance. A selection is expected in spring.
