San Antonio Fire and Police Pension Fund hired MetLife to manage a $90 million enhanced guaranteed indexed fixed-income portfolio. The $1 billion pension fund will use one of MetLifes INDEX TRACK funds, which is managed by Loomis Sayles and is guaranteed by MetLife. The money was in an indexed domestic fixed-income portfolio managed by Mitchell Hutchins. The move was made to gain additional returns that were guaranteed, said Warren Schott, investment officer of the pension fund. Mitchell Hutchins continues to manage $140 million in a Russell 1000 value index fund.
