Seattle City Employees Retirement System will issue an RFP Aug. 30 for three or four international equity managers and two international fixed-income managers due to contract expirations, said Mel Robertson, acting executive director for the $1.5 billion fund. Proposals are due Oct. 15. Prospective managers should download a copy of the RFP from www.wurts.com, he said; phone calls will not be accepted. Incumbent international equity managers New Africa Group, State Street Global Advisors and Seligman Henderson, running a total of $270 million, and incumbent international fixed-income managers Barclays Global Investors and Fiduciary Trust, running a total of $140 million, are all expected to rebid. Portfolio sizes and styles were not available. A decision is expected by January. Separately, Mr. Robertson said, the board decided to wait until next year to begin searching for domestic small-cap, midcap and large-cap managers, also due to contract expirations.
