Illinois Teachers' Retirement System, Springfield, is searching for two directors, for real estate and for investments, at the $22 billion plan, said Jon Baumann, executive director. Both positions are new and will report to Charles Self, CIO. The director of real estate will oversee outside real estate managers, which manage 14% of the plan's assets. The director of investments will have day-to-day oversight of all investment classes except real estate. Hudepohl & Associates is conducting the searches.
