PV of Cash Flows as rates change Bond Value PV of coupons PV of par Bond Value PV annuity PV of lump sum Remember,as interest rates increase,the PVs decrease So,as interest rates increase,bond prices decrease and vice versa 4
4 PV of Cash Flows as Rates Change n Bond Value = PV of coupons + PV of par n Bond Value = PV annuity + PV of lump sum n Remember, as interest rates increase, the PVs decrease n So, as interest rates increase, bond prices decrease and vice versa
Valuing a Discount Bond with Annual Coupons Consider a bond with a coupon rate of 10%and coupons paid annually.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)]/.11+$1,000/(1.11)5 ■B=$369.59+593.45=$963.04 0 Using the calculator: ■ N=5;I/Y=11;PMT=100;FV=1,000 ■CPT PV=-963.04
5 Valuing a Discount Bond with Annual Coupons n Consider a bond with a coupon rate of 10% and coupons paid annually. 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? q Using the formula: n B = PV of annuity + PV of lump sum n B = $100[1 – 1/(1.11)5] / .11 + $1,000 / (1.11)5 n B = $369.59 + 593.45 = $963.04 q Using the calculator: n N = 5; I/Y = 11; PMT = 100; FV = 1,000 n CPT PV = -963.04
Valuing a Premium Bond with Annual Coupons Suppose you are looking at a bond that has a 10% annual coupon and a face value of $1,000.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+$1,000/(1.08)20 ■B=$981.81+214.55=$1,196.36 Using the calculator: N=20;IY=8;PMT=100;FV=1,000 CPT PV=-1,196.36 6

There are 20 years to maturity and the yield to maturity is 8%. What is the price of this bond? q Using the formula: n B = PV of annuity + PV of lump sum n B = $100[1 – 1/(1.08)20] / .08 + $1,000 / (1.08)20 n B = $981.81 + 214.55 = $1,196.36 q Using the calculator: n N = 20; I/Y = 8; PMT = 100; FV = 1,000 n CPT PV = -1,196.36

7 Graphical Relationship Between Price and YTM
Bond Prices:Relationship Between Coupon and Yield If YTM coupon rate,then par value bond price If YTM>coupon rate,then par value bond price a Why? Price below par=“discount'”bond If YTM coupon rate,then par value bond price a Why? ▣Price above par=“premium”bond 8
8 Bond Prices: Relationship Between Coupon and Yield n If YTM = coupon rate, then par value = bond price n If YTM > coupon rate, then par value > bond price q Why? q Price below par = “discount” bond n If YTM < coupon rate, then par value < bond price q Why? q Price above par = “premium” bond
