What is the after-tax holding-period return on the bond? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Answer is complete and correct. 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.) 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.) A newly issued bond pays its coupons once annually.
