In mid-2009, Rite Aid had CCC-rated, 17-year bonds outstanding with a yield to maturity of 17.3%. At the time, similar maturity Treasuries had a yield of 4%.

Suppose the market risk premium is 4% and you believe Rite Aid's bonds have a beta of 0.39. The expected loss rate of these bonds in the event of default is

52%.

a. What annual probability of default would be consistent with the yield to maturity of these bonds in mid-2009?(Round to two decimal places.)

b. In mid-2015, Rite-Aid's bonds had a yield of 7.5%, while similar maturity Treasuries had a yield of 1.3%.

What probability of default would you estimate now? (Round to two decimal places.)
