When Idaho became a state, the United States Congress granted certain federal lands to be held in trust to generate revenue for education and other important purposes. Those land grants are Idaho’s endowment lands.

The Endowment Fund Investment Board (EFIB) manages investment of the income generated by Idaho’s endowment lands. The EFIB also manages financial assets for SIF (State Insurance Fund), Idaho Department of Environmental Quality, Idaho Department of Fish and Game, Idaho Department of Parks and Recreation and Idaho Department of Lands. In addition, EFIB manages a Credit Enhancement Program to reduce the cost of financing public school bonds.

The management of all assets, except for SIF, is governed by the Idaho Uniform Prudent Investor Act.
