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....

Better balance sheets, higher resale values, the trend away from subprime financing, and a lineup of vehicles that give better mileage (even with trucks acounting for 50% of sales) with the shift to lighter crossover vehicles, will help Detroit automakers face higher gas prices. These factors should help prevent a replay of the very serious problems of 2008, when gas prices exceeded $4.00 a gallon and the U.S. faced a financial crisis. At that time in 2008 vehicle sales declined by 18% and truck sales were down by 25%, according to Credit Suisse.

The Nuclear Safety Commission of Japan, one of two safety regulators in Japan, met in October 2010. At that meeting a presentation by Takanori Tanaka, head of the government supported Nuclear Power Engineering Center, advocated new technologies that would reduce risk in the event of earthquakes and tsunamis. The presentation focussed on new plants and did not go into retrofitting old plants with new backup solutions for cooling in the event of electrical failure. A recent article by Hitachi researchers brought up the idea of isolation condensers which could provide temporary power supplies in the event of electrical failure. One such device was on No. 1 reactor at Fukushima (built in 1971), and worked after the quake but later failed. The views of nuclear engineers at Hitachi discussed here show that cost remains a constraint in the design of nuclear reactor cooling systems, and redundancy with several layers of diverse backup systems for cooling are not being pushed by companies building the reactors. See the group articles for G.E.'s Mark 1 system which show cost and easier to build were factors behind the smaller containment systems favored for that design. Fukushima plant uses the Mark 1 reactors. Without independent safety regulation that does not rely on the companies for analysis and solutions, regulation risks becoming too dependent on companies for coming up with the strong safety precautions that are absolutely essential. These safety precautions can succumb to cost pressures....
