Assume you have a 1-year investment horizon and are trying to choose among three bonds. All have the same degree of default risk and mature in 10 years. The first is a zero-coupon bond that pays $1,000 at maturity. The second has an 8% coupon rate and pays the $80 coupon once per year. The third has a 10% coupon rate and pays the $100 coupon once per year.

d. If your tax bracket is 30% on ordinary income and 20% on capital gains income, what will be the after-tax rate of return on zero coupon

. Recalculate your answers to (b)(d) under the assumption that you expect the yields to maturity on each bond to be 7% at the beginning of next year. (Round your answers to 2 decimal places.)
