Los Angeles County Employees Retirement Association will issue an RFI to Watson Wyatt, Gabriel Roeder & Smith, Milliman & Robertson, Segal and William M. Mercer about providing actuarial valuation, consulting and auditing services for the $24.8 billion fund. The board agreed with staff that a "full-blown RFP was not necessary. In the past 17 months, LACERA has issued two actuarial RFPs one for audit services and the other for actuarial services and has received full proposals from the firms listed above. CEO Marsha D. Richter told the board the RFI would focus on key issues as well as determine the engagement teams these firms would assign to LACERA and explain their qualifications and fee quotes. LACERA currently has a three-year contract with Watson Wyatt that includes a "termination for convenience clause, Ms. Richter told the board. Under this clause, the fund would have to give Watson Wyatt a 10-day written notice to terminate the contract, said David L. Muir, chief counsel to LACERA.
