Washington State Investment Board, Olympia, is surveying the services available from private equity consultants in anticipation of a formal search to be launched next spring. The fund plans to hire a consultant to replace Brinson Partners by the end of 2000. A Brinson spokesman declined to comment. The $40 billion pension fund has 8.5% of its assets invested in private equity; the target is 15%. The funds request for information indicates it prefers firms that can source deals as well as provide performance measurement and reporting, and monitor and manage financial transactions, but would consider dividing the roles between deal finders and the other functions. Responses are due by Jan. 12.
