A firm intends to issue callable, perpetual bonds with annual coupon payments and a
par value of $1,000. The bonds are callable at $1,260. One-year interest rates are 8
percent. There is a 60 percent probability that long-term interest rates one year from
today will be 12 percent, and a 40 percent probability that they will be 4 percent.
Assuming that the bonds will be called if interest rates fall, what annual coupon
should the bond pay in order to sell at par value?
