At t = 0, a 3-year, 7% coupon corporate bond with face value $1,000 is trading at a credit spread of 15%. The risk free rate is constant and equal to 4% for all maturities. The recovery rate on the corporate bond is 40% if a default occurs. At t = 0, the market believes that the probability of default in the first year, P1, is 20%, and the probability of default in the second year, P₂, is 30%. Assume investors are risk neutral.
 
a)  At t = 0, what is the price of the bond?
 
b)  At t = 0, what is the market's belief about the default probability in the third year, P₃?
 
c)  If you buy $10,000 present value worth of the bond at t = 0, and you will liquidate the position at t = 1, what is the expected total amount of money you will have at t = 1? (Note: you may answer this question using a long way or a very short way.)
 
d)  Suppose the same company also has a 3-year zero coupon bond outstanding with face value $500. The bond is junior to the previous bond, and the recovery rate is therefore 0%. What is the value of this junior bond at t = 0? (Hint: you need to use P₁, P₂, and P₃.)
