The Indiana Public Employees' Retirement Fund, Indianapolis, is searching for an actuarial consulting firm to provide valuations, recommend actuarial assumptions and advise on the fiscal impact of legislative or regulatory proposals. The $10.4 billion fund is offering a one-year contract, renewable up to four times under the same terms at Indiana PERF's option. The RFP notes that the selected firm "must not seek to unreasonably limit its liability for negligence." Proposals are due June 2, and the fund's board hopes to make a decision in mid-June. Fund officials weren't available to comment on whether McCready & Keene, the current actuary, would be invited to submit a proposal.
