The PRIT Fund consists of the General Allocation Account or “PRIT Core”, which is comprised of a diverse set of investment accounts. No element in an investment strategy is more critical to the realization of long-term investment objectives than the allocation of assets. The PRIM Board believes it is important to control risk through diversification, and, therefore, it invests in other asset classes including real estate, core fixed income, and international investments.
