Federal Thrift Savings Plan will issue request for proposals (RFPs) for managers to handle its investment options, Pensions & Investments reports. The defined contribution plan is seeking to award the management of four externally managed investment funds worth $150 billion.

BlackRock is presently managing the four options, which will be put up for bid in 2012. The RFPs will consist of a fixed-income index fund, a common-stock index fund, a small-cap equity index fund, an international stock index fund and a government securities fund of U.S. Treasuries.
