Kessler says the assumption that pension systems such as Calpers (California Public Employees Retirement System), can make returns of 7.5% is fantasy considering that U.S. Treasury bonds are yielding 1.74%. Calpers reduced its expected rate of return on its portfolio to 7.5% fom 7.75% in June 2012. Public pension funds in Illinois use 8.18% for expected returns. U.S. public companies with defined benefit pension plan assets of $1.3 trillion use an expected rate of return of 7.5%, even though these assets have return of 5.6% since 2000. Kessler's estimate for expected rate of return is about 3%- fixed income yielding negative real rates of return and pulling returns down. For equities he estimates return at the total of inflation component at +2%, productivity component at +2%, and multiple expansion at -1% because interest rates are at zero.
