The par value is $1,000 and the bond has 5 years to maturity. The yield to maturity is 11%. What is the value of the bond? Using the formula: B = PV of annuity + PV of lump sum B = 100[1 – 1/(1.11) 5 ] / .11 + 1,000 / (1.11) 5 B = 369.59 + 593.45 = 963.04 Using the calculator: N = 5; I/Y = 11; PMT = 100; FV = 1,000 CPT PV = 963.04 77 FIN 3716 Valuing a Premium Bond with Annual Valuing a Premium Bond with Annual Coupons Coupons Suppose you are looking at a bond that has a 10% annual coupon and a face value of $1000. There are 20 years to maturity and the yield to maturity is 8%. What is the price of this bond? Using the formula: B = PV of annuity + PV of lump sum B = 100[1 – 1/(1.08) 20 ] / .08 + 1000 / (1.08) 20 B = 981.81 + 214.55 = 1196.36 Using the calculator: N = 20; I/Y = 8; PMT = 100; FV = 1000 CPT PV = 1,196.36 78 FIN 3716 Graphical Relationship Between Price Graphical Relationship Between Price and Yieldtomaturity (YTM) and Yieldtomaturity (YTM) 600 700 800 900 1000 1100 1200 1300 1400 1500 0% 2% 4% 6% 8% 10% 12% 14% Bond Price Yieldtomaturity (YTM) 79 FIN 3716 Bond Prices: Relationship Between Bond Prices: Relationship Between Coupon and Yield Coupon and Yield If YTM = coupon rate, then par value = bond price If YTM > coupon rate, then par value > bond price Why? The discount provides yield above coupon rate Price below par value, called a discount bond If YTM < coupon rate, then par value < bond price Why? Higher coupon rate causes value above par Price above par value, called a premium bond 710 FIN 3716 The Bond Pricing Equation The Bond Pricing Equation t t r) (1 F r r) (1 1 1 C Value Bond + + + = 711...
