Suppose that a 10-year bond with a face value of $1000 pays semiannual coupons at a rate of 4.2% per half year. The issuer of the bond has the option to redeem it at the time of the 16th coupon for $2200 or at maturity for $2000. Find the price that will guarantee an investor a yield rate of at least 12.6% convertible semiannually, regardless of when the bond is redeemed.
