Houston Police Officers Pension System is sorting through responses to RFPs issued earlier this fall for two managers and a new consultant, according to Tim Ng, chief investment officer. The $1.7 billion defined benefit plan is selecting a domestic fixed-income manager to run $100 million and a high-yield manager to run $60 million. The domestic bond manager is to be named in January; no timetable has been set for the high-yield manager decision. Northern Trust, ARM Capital, Delaware International and PIMCO are the systems current fixed-income managers. MacKay-Shields is assisting. The first task for the new consultant, which should be named in January, will be assisting in restructuring the systems domestic equity portfolio, said Mr. Ng.
