Katie purchases a 15 year par value bond with 5% semiannual coupons at a price of 2345. The bond can be called at par value X on any coupon date starting at the end of year 10. The price guarantees that Katie will receive a nominal semiannual yield of at least 4%. Mark purchases a 15 year par value bond identical to Katie's except it is not callable. Assuming the same yield, what is the price of Mark's bond? NO EXCEL!!!!
