Andy Kessler: The Pension Rate-of-Return Fantasy - WSJ.com: "In June of 2012, Calpers lowered the expected rate of return on its portfolio to 7.5% from 7.75%. Mr. Milligan suggested 7.25%. Calpers had last dropped the rate in 2004, from 8.25%. But even the 7.5% return is fiction. Wall Street would laugh if the matter weren't so serious. And the trouble is not just in California. Public-pension funds in Illinois use an average of 8.18% expected returns. According to the actuarial firm Millman, the 100 top U.S. public companies with defined benefit pension assets of $1.3 trillion have an average expected rate of return of 7.5%. Three of them are over 9%. (Since 2000, these assets have returned 5.6%.) Who wouldn't want 7.5%-8% returns these days? Ten-year U.S. Treasury bonds are paying 1.74%. There is almost zero probability that Calpers will earn 7.5% on its $255 billion anytime soon."
