Montana Board of Investments, Helena, plans to shift up to $750 million in active non-core fixed income to external management, said Carroll South, executive director. The fund will use money from its two internally managed core fixed-income pools, which total $3.5 billion, to fund the non-core portfolio. At least one manager is being sought to run the portfolio, either in separate or commingled accounts. The amount of the allocation depends on the number of managers selected. The board may hire additional respondents up to two years after the first contract is signed. A selection is expected in spring or summer, according to the RFP. The board oversees $13 billion, $8 billion of which is in pension assets.
