Taunton (Mass.) Contributory Retirement System re-issued RFPs for core/income-producing and value-added real estate managers, after the June hiring of ING Clarion Lion Properties Fund fell through. The search is part of $134 million system's effort to boost its real estate allocation to 8% from 6%. The source of funding has not been decided, said Kevin Leonard, the Segal Advisors consultant who is assisting. RFPs are available from Carol Tam of Segal Advisors at [email protected]; proposals are due Jan. 13. Paul Slivinski, executive director of the system, did not return a call for comment.
