Fairfax County Educational Employees' Supplemental Retirement System, Springfield, Va., hired active domestic large-cap relative value equity managers Dodge & Cox and Aronson + Johnson + Ortiz to run $104 million and $78 million, respectively. The $1.37 billion system will partially fund the hirings with $160 million that was parked in a Mellon Russell 1000 value index fund after it terminated Oppenheimer last year, said Alan Belstock, finance director. Oppenheimer ran the money in a similar style. The balance will come from trimming other portfolios, he said. The hirings were prompted by an asset-liability study completed late last year.
