Bonds and their Valuation
Instructor: Sanam TaimoorInstitute of Business Management
Topics
• Bonds and bond’s characteristics• Types of bonds• Bond Valuation• Yield to Maturity• Calculating YTM• Bond Price and Yield relationship
BOND
• A long term contract under which a borrower agrees to make payments of interest and principal on specific date, to the holders of the bond
• Bond Indenture– Is a legal document that specifies both the rights
of the bondholders and duties of the issuing corporation
Types of Bonds
• Treasury Bonds– Issued by the government
• Corporate Bonds– Issued by companies
• Municipal Bonds– Issued by local governments
• Foreign Bonds– Issued by foreign governments or companies
Characteristics of a Bond• Par Value– the stated face value of a bond
• Coupon Interest Rate– the fixed “rate of interest” which remains the
same throughout the life of the bond• Maturity Date– Specified maturity date on which par value must
be paid• Call Option– It gives the issuer the opportunity to repurchase
the bonds prior to maturity
Other Types of Bonds
• Floating Rate Bonds• Zero Coupon Bonds• Perpetual Bonds• Convertible Bonds
Bond Valuation
NkNkB dd PVIFMPVIFAINTV ,,
INT = Coupon Interest M = Par valueKd = Market rate of interestN = Number of years before the bond matures
Example
• Bond C has a $1,000 face value and provides an 8% annual coupon for 30 years. The appropriate discount rate is 10%. What is the value of the coupon bond?
– VB = $80 (PVIFA10%, 30) + $1,000 (PVIF10%, 30) = $80 (9.427) + $1,000 (.057)= $754.16 + $57.00
= $811.16.
Perpetual Bond Example
• Bond P has a $1,000 face value and provides an 8% coupon. The appropriate discount rate is 10%. What is the value of the perpetual bond?
VB = $80 / 10% = $800

• Bond Z has a $1,000 face value and a 30-year life. The appropriate discount rate is 10%. What is the value of the zero-coupon bond?

V = $1,000 (PVIF10%, 30)= $1,000 (.057)
= $57.00
Semi Annual Compounding
• Some Bonds pay interest twice a year
• Adjustments needed– Divide kd by 2
–Multiply N by 2–Divide INT by 2
• Bond C has a $1,000 face value and provides an 8% semiannual coupon for 15 years. The appropriate discount rate is 10% (annual rate). What is the value of the coupon bond?
– VB = $40 (PVIFA5%, 30) + $1,000 (PVIF5%, 30) = $40 (15.373) + $1,000 (.231)
= $614.92 + $231.00= $845.92
Semi Annual Compounding Example
Yield to Maturity
• The rate of return (Kd) that investors earn if they buy a bond at a specified price and hold it until maturity
• In other words it is the rate of interest that sets the present value of the bond’s expected future cash-flow stream equal to the bond’s current market price
Calculating YTM
Consider a $1,000 par value bond with the following characteristics : a current market price
of $ 761; 12 years until maturity and an 8% coupon rate .
What is the YTM?
Try 10%:
$761 = $80(PVIFA10%,12) + $1,000(PVIF10%,12)
$761 = $80(6.814) + $1,000(.319) $761 = $545.12 + $319
= $864.12[Rate is too low!]
Calculating YTM
Try 15%
$761 = $80(PVIFA 15%,12) + $1,000(PVIF 15%, 12) $761 = $80(5.421) + $1,000(.187)$761 = $433.68 + $187
= $620.68[Rate is too high!]
Calculating YTM

• Answer: 12.90%

• Julie Miller want to determine the YTM for an issue of outstanding bonds at Basket Wonders (BW). BW has an issue of 10% annual coupon bonds with 15 years left to maturity. The bonds have a current market value of $1,250.

Calculating YTM
Bond Price- Interest Rate Relationship
• A bond’s price and interest rates are inversely related;– When interest rates rise, bond’s price falls – When interest rates fall, bond’s prices rises

Bond Price- Interest Rate Relationship
• Assume that the required rate of return on a 15-year, 10% coupon-paying bond rises from 10% to 12%. What happens to the bond price?
• When interest rates rise, then the market required rates of return rise and bond prices will fall

Bond Price- Interest Rate Relationship
• Discount Bond -- The market required rate of return exceeds the coupon rate (Par > P0 ).
• Premium Bond -- The coupon rate exceeds the market required rate of return (P0 > Par).
• Par Bond -- The coupon rate equals the market required rate of return (P0 = Par).
