The annual assumed rate of investment return is widely overestimated in the largest U.S. public pension systems. 59 of the largest pension systems use 8% return, 17 use 8.25%, 12 use 8.50%, and 32 use between 7.5 and 7.75%, according to the National Association of State Retirement Administrators. This is unrealistic in today's financial markets and overstates the extent to which the pension funds are funded. Calpers, California Public Employees Retirement System, is one of the largest pension systems that uses 7.75% assumed investment return. The Board of the $227 billion pension fund decided to retain the 7.75% return, against the advice of the fund's actuary, at a recent meeting. Calpers actuary had recommended a modest drop to 7.5%. The rate is used as a discount rate to calculate the present value of benefits owed to retirees in the future. The lower the discount rate the higher the pension fund's liabilities, probably requiring a higher contribution by local governments. Corporations use the interest rate on highly rated corporate bonds yielding about 6%, as their pension funds discount rate. An expert at Northwestern University suggests the use of a discount rate based on Treasury yields, which is now 4% for long term bonds. Even the modest drop to 7.5% would increase the amount local governments in California would be required to give the state pension fund by 1.5% to 3% of their payroll in many cases according to Calpers. The budget pain is the reason why state pension funds are sticking with unrealistic past returns....
