Wyoming Retirement System, Cheyenne, might make a 3% to 5% allocation to alternative investments, its first, said Harry Wales, deputy director. The board of the $4.3 billion system will hear a presentation on private equity at its Nov. 21 meeting. System officials have not yet determined which other types of alternatives they will consider, and it will be "a long while" before any manager searches are begun, he said. It is too soon to predict how the potential new allocation might be funded, he added. The plan's asset allocation is 59% equity, 38% fixed income and 3% real estate. Buck Consultants is assisting.
