Oklahoma Public Employees Retirement System, Oklahoma City, rehired Cavanaugh Macdonald Consulting as actuarial consultant, said Joseph A. Fox, executive director, in an email.
The retirement system issued an RFP in November because Cavanaugh Macdonald's contract expires June 30.
There were no other finalists.
As of Sept. 30, the board oversaw $10.2 billion in assets for its defined benefit plan for public employees and a defined benefit plan for justices and judges.
