The plan is nearing a global core equity manager search as it looks to fill a new underlying 20% allocation.
The investment consultant was also rehired in 2019 following a similar RFP process.

The plan will also terminate two existing hedge fund managers.
The retirement system is looking to invest up to $15 million to the strategy.
