Seattle City Employees Retirement System is searching for a manager to run up to $60 million in active domestic midcap equities, said Norm Ruggles, executive director. The search is part of the $1.6 billion system's "normal contract review process," and its current contract with Wall Street Associates is expiring, he said. Wall Street Associates currently manages $40 million, and system officials are considering taking an additional $20 million from a domestic equity index fund, Mr. Ruggles said. Further information is available from the system, which is handing the search internally. The system's board is expected to make a selection during the first quarter.
