As expected, the $4.3 billion New Mexico Public Employees Retirement Association, Santa Fe, is issuing RFPs for four domestic equity managers for a total of about $2.1 billion. The plan will seek responses for active small-cap growth, small-cap value, passive core equity and passive growth managers. The allocation to each will be determined before final selection. RFPs are due by July 15. Finalists will be chosen by Aug. 12. Hirings are expected by the end of August. The search is required by state law at the end of the contract period, said Lorraine Ward, deputy director-investments.
