Problem 14-31 A newly issued bond pays its coupons once annually. Its coupon rate is 7%, its maturity is 20 years, and its yield to maturity is 9%. a. Find the holding-period return for a 1-year investment period if the bond is selling at a yield to maturity of 8% by the end of the year. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Holding-period return 19.15 % b. If you sell the bond after one year, what taxes will you owe if the tax rate on interest income is 40% and the tax rate on capital gains income is 30%? The bond is subject to original-issue discount tax treatment. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Tax on interest income $ 13.47 Tax on capital gain $ 8.76 Total taxes c. What is the after-tax holding-period return on the bond? (Do not round intermediate calculations. Round your answer to 2 decimal places.) After-tax holding-period return 12.55 % d. Find the realized compound yield before taxes for a 2-year holding period, assuming that (i) you sell the bond after two years, (ii) the bond yield is 8% at the end of the second year, and (iii) the coupon can be reinvested for one year at a 3% interest rate. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Realized compound yield before taxes 9.00 % e. Use the tax rates in part (b) to compute the after-tax 2-year realized compound yield. Remember to take account of OID tax rules. (Do not round intermediate calculations. Round your answer to 2 decimal places.) After-tax 2-year realized compound yield 5.39 %
