DiNapoli announced today that he’s approved a recommendation by the State Retirement System Actuary to reduce, from 6.8 percent to 5.9 percent, the assumed rate of return (RoR) on investments by the $268 billion Common Retirement Fund, which underwrites the New York State and Local Employee Retirement System (NYSLERS) and Police and Fire Retirement System (PFRS), of which the comptroller is the sole trustee.
