Calculation 2 (Calculation, 10 points) What is the annual yield-to-maturity of a bond with a periodicity of 2, for a 5-year, zero-coupon bond priced at 80 per 100 of par value? (Remember that for any credit you must show all your work.) Calculation 3 (Calculation, 10 points) A 5-year, 5% semi-annual coupon payment corporate bond is priced at 105 per 100 of par value. The bond's yield-to-maturity, quoted on a semi-annual bond basis, is 3.8%. What is the yield-to-maturity based on monthly periodicity? (Remember that for any credit you must show all your work.) Calculation 4 (Calculation, 10 points) An investor buys a three-year bond with a 4% coupon rate paid annually. The bond, with a yield-to-maturity of 3%, is purchased at a price of 106 per 100 of par value. Assuming a 5-basis point change in yield-to-maturity, what is the bond's approximate modified duration? (Remember that for any credit you must show all your work.)
