a. Serveal years ago, Castles in the Sand, Inc., issued bonds at face value at a yeild to maturity of 6.2 percent. Now, with 8 years left until the maturity of the bonds, the company has run into hard times and the yield to maturity on the bonds has increased to 15 percent. What has happended to the price of the bond now?

b. Suppose that investors believe that Castles can make good the promised coupon payments, but that the company will go bankrupt when the bond matures and the principal comes due. The expectation is that investors will receive only 80 percent of face value at maturity. if they buy the bond today, what yield to maturity do they expect to receive?
