15. Assume that five years ago a firm issued a 30-year, $1,000 par value bond that had an annual coupon rate of 8.00 percent (but makes semi-annual coupon payments). Also assume that the bonds current nominal annual yield-to-maturity is 10.0 percent. Now assume that the firm has the option of calling this bond in another 5 years (when the bond will be a 20-year bond), but at a call price of $1,160. Given this information, determine the current yield-to-call for this bond. A. 15.99% B. 15.25% C. 14.51% D. 15.62% E. 14.88%
