Asset allocation
PRIM believes that over the long‐term, asset allocation is the most critical component to achieve its investment objectives and meet its obligations. The adopted asset allocation that is available through investment in the PRIT Fund provides participating retirement systems with a diversified portfolio of active and passive investment strategies across several asset classes. In order to achieve our long-term return objectives, a significant portion of the Fund is allocated to global equity investments, which typically generate higher returns, but can also experience more volatility.
