CHAPTER 15 B-
8. a. The price of the bond today is the present value of the expected price in one year. So, the price
of the bond in one year if interest rates increase will be:
If interest rates fall, the price if the bond in one year will be:
Now we can find the price of the bond today, which will be:
For students who have studied term structure, the assumption of risk-neutrality implies that the
b. If the bond is callable, then the bond value will be less than the amount computed in part a. If
9. The price of the bond today is the present value of the expected price in one year. The bond will be
called whenever the price of the bond is greater than the call price of $1,150. First, we need to find
the expected price in one year. If interest rates increase next year, the price of the bond will be the
present value of the perpetual interest payments, so:
This is lower than the call price, so the bond will not be called. If the interest rates fall next year, the
price of the bond will be:
This is greater than the call price, so the bond will be called. The present value of the expected value
of the bond price in one year, plus the coupon payment made in one year, is:
10. If interest rates rise, the price of the bonds will fall. If the price of the bonds is low, the company will
not call them. The firm would be foolish to pay the call price for something worth less than the call
price. In this case, the bondholders will receive the coupon payment, C, plus the present value of the
remaining payments. So, if interest rates rise, the price of the bonds in one year will be:
P1 = C + C / .10
