Washington State Investment Board, Olympia, is searching for international developed-market index and enhanced index equity managers for the $40 billion system. Portfolio sizes have not been finalized. Contracts with current managers Delaware International, Putnam, Dresdner RCM, Artisan, Pyrford and Nicholas-Applegate expire on June 30, 2004, said Liz Mendizabal, spokeswoman; those managers can rebid. As of June 30, the system had $2.5 billion in international equity investments. Selections are expected in February, with four-year contracts to begin July 1. Callan Associates is assisting.
