Ohio Bureau of Workers Compensation, Columbus, May 17 issued an RFP for a consultant. A previous search was scrapped due to problems with the RFP, said Robert Cowan, CIO for the $17.5 billion fund. Proposals will be due June 7. The number of consultants that will be hired is still undetermined, he said. Contracts of the incumbents Gray & Co., Fiduciary Investment Solutions and Callan Associates have expired; all three are expected to rebid. A decision is expected by July.
