Iowa Public Employees' Retirement System, Des Moines, is searching for an actuarial consultant.
The $40.1 billion pension fund issued an RFP because the contract of current consultant Cavanaugh Macdonald Consulting will expire on June 30, spokeswoman Shawna Lode said in an email.
The firm is invited to rebid, she said.
The RFP is available on IPERS' website. Proposals are due at 4 p.m. CST on Feb. 17. A selection will be made in March, Ms. Lode said.
