The Wall Street Journal reports that the current rate on 6-year Treasury bonds is 6.20 percent, the rate on 13-year Treasury bonds is 6.60 percent, and the rate on a 13-year corporate bond issued by MHM Corp. is 8.05 percent. Assume that the maturity risk premium is zero. If the default risk premium and liquidity risk premium on a 6-year corporate bond issued by MHM Corp. are the same as those on the 13-year corporate bond, calculate the current rate on MHM Corp.s 6-year corporate bond.
