Sample Problem #1 Solving for Price A. Given a 4-year bond wih a $1000 face value and a 5% coupon rae, annual compounding (annual periodic ineres paymens), find he price of he bond if he marke rae for similar bonds is 6%. B. umerical Soluion 1. Sep 1: Calculae he coupon paymen CP = Par(CR) = $1000 x 0.05 = $50 2. Sep 2: Assign values o he variables 3. Sep 3: Apply he formula PRICE PV 4 1 1,000 50 4 (1.06) (1.06) 1 C. Tabular Soluion $965.35 1. Sep 1 & Sep 2: Same as above 2. Sep 3: Deermine able values for boh he annuiy and lump sum (ener he ables wih n and k d ) 3. Sep 4: Apply he formula Price = PV = V B = 50(PVIFA 4, 6% ) + 1,000(PVIF 4, 6% ) Price = PV = V B = 50(3.4651) + 1,000(0.7921) = $965.355 D. Calculaor soluion I 1. Sep 1 & Sep 2: Same as above 2. Sep 3: Inpu variables ino calculaor 3. Sep 4: Compue price Cp PV Page 2 Fin 311 Chaper 06 Handou R1.Doc
BOD PRICE Sample Problem #2 Solving for Yield o Mauriy Given Price A. Assume now ha you are given a quoe on he price for he bond in Problem #1 and i is selling for $932.25. Wha is he yield o mauriy (marke rae for deb) for he bond? B. umerical and Tabular Soluions require rial and error o solve. C. Calculaor Soluion 1. Sep 1: Assign values o he variables 2. Sep 2: Inpu variables ino calculaor 3. Compue r d Cp I PV V: Bond Pricing Principles A. These five simple rules will allow you o beer undersand he relaionship beween PRICE and yield (k d ) for a given bond (inverse relaionship) 1. When coupon rae = k d he bond sells a par value (PRICE = Par) 2. When coupon rae > k d he bond sells a a premium (PRICE > Par) 3. When coupon rae < k d he bond sells a a discoun (PRICE < Par) 4. A mauriy PRICE = Par for all values of k d 5. The longer he ime o mauriy he greaer he premium (discoun) B. Discuss he graph below BOD VALUES $2,000.00 $1,500.00 $1,000.00 PREMIUM BOD VALUE PAR BOD VALUE $500.00 DISCOUT BOD VALUE $0.00 0 10 20 30 40 YEARS TO MATURITY Fin 311 Chaper 06 Handou R1.Doc Page 3
Bond fac #1: There is an inverse relaionship beween ineres raes and bond prices. If ineres raes increase, bond prices decrease. If ineres raes decrease, bond prices increase. Bond fac #2: Ineres rae risk is he risk ha if ineres raes increase, bond prices will decrease. All else he same, a longer erm bond will have more ineres rae risk han a shorer erm bond. Bond fac #3: All else he same, here is an inverse relaionship beween he coupon rae and ineres rae risk. A bond wih a lower coupon has more ineres rae risk han a bond wih a higher coupon.

Zero coupon bonds Suppose we have he following bond: Par = $1,000 Coupon rae = 0% Mauriy = 15 years YTM = 9% Wha is he price of he bond? I Cp PV Wha is he price of he bond if we use semi-annual compounding? I Cp PV Fin 311 Chaper 06 Handou R1.Doc Page 5
