Webster (Mass.) Retirement System issued an RFP for at least one manager to run a total of $1.8 million in core or value-added real estate. The manager is being added for diversification, and the source of funding is undetermined. The system currently has less than $1 million in real estate, said Gerry Wentworth, board administrator of the $18 million fund. Wainwright Investment Counsel is assisting. The RFP is available on Wainwrights website at www.winvcounsel.com. Proposals are due at 4 p.m. EDT Aug. 29. No timetable for a decision was given.
