Assume that you are considering the purchase of a 20-year, noncallable bond with an annual coupon rate of 9.5%. The bond has a face value of $1,000, and it makes semiannual interest payments. If you require a 10.7% nominal yield to maturity (YTM) on this investment, what is the maximum price you should be willing to pay for the bond?
