State of Wisconsin Investment Board, Madison, issued an RFI for transition managers to place on a pre-approved list for future transitions made by the $75 billion fund. Transitions, which may range in size from $100 million to $2.5 billion, could be for any of the public asset classes: domestic, international and emerging markets equities; and domestic and international fixed income, including high yield and TIPS, according to the RFI. This is the first time the board has looked at hiring firms for transition management services, said Vicki Hearing, public information officer. The RFI is available at www.swib.state.wi.us. Submissions are due Oct. 31.
