1. Fill out the table below. ( 40 points) The first three columns are inputs. P and CR are, respectively, the price and coupon rate of an annual 1.5-year coupon bond. TR is the marginal tax rate. The face value is $1,000. The last four columns are outputs. yp is the pretax yield. ya is the after-tax yield implied by the potentially-flawed formula. ya' is the after-tax yield assuming capital gains are only taxed at maturity and coupon payments are taxed normally. ya is the after-tax yield assuming capital gains are only taxed at maturity and coupon payments are tax-exempt.
