3. Bond valuation
The process of bond valuation is based on the fundamental concept that the current price of a security can be determined by calculating the present value of the cash flows that the security will generate in the future.
There is a consistent and predictable relationship between a bond’s coupon rate, its par value, a bondholder’s required return, and the bond’s resulting intrinsic value. Trading at a discount, trading at a premium, and trading at par refer to particular relationships between a bond’s intrinsic value and its par value. This also results from the relationship between a bond’s coupon rate and a bondholder’s required rate of return.
Remember, a bond’s coupon rate partially determines the interest-based return that a bond pay, and a bondholder’s required return reflects the return that a bondholder to receive from a given investment.
The mathematics of bond valuation imply a predictable relationship between the bond’s coupon rate, the bondholder’s required return, the bond’s par value, and its intrinsic value. These relationships can be summarized as follows:
• | When the bond’s coupon rate is equal to the bondholder’s required return, the bond’s intrinsic value will equal its par value, and the bond will trade at par. |
• | When the bond’s coupon rate is greater than the bondholder’s required return, the bond’s intrinsic value will its par value, and the bond will trade at a premium. |
• | When the bond’s coupon rate is less than the bondholder’s required return, the bond’s intrinsic value will be less than its par value, and the bond will trade at . |
For example, assume Amelia wants to earn a return of 9.00% and is offered the opportunity to purchase a $1,000 par value bond that pays a 9.00% coupon rate (distributed semiannually) with three years remaining to maturity. The following formula can be used to compute the bond’s intrinsic value:
Intrinsic ValueIntrinsic Value | = = | A(1+C)1+A(1+C)2+A(1+C)3+A(1+C)4+A(1+C)5+A(1+C)6+B(1+C)6A1+C1+A1+C2+A1+C3+A1+C4+A1+C5+A1+C6+B1+C6 |
Complete the following table by identifying the appropriate corresponding variables used in the equation.
Unknown |
Variable Name |
Variable Value |
---|---|---|
A | ||
B | $1,000 | |
C | Semiannual required return |
Based on this equation and the data, it is to expect that Amelia’s potential bond investment is currently exhibiting an intrinsic value equal to $1,000.
Now, consider the situation in which Amelia wants to earn a return of 12%, but the bond being considered for purchase offers a coupon rate of 9.00%. Again, assume that the bond pays semiannual interest payments and has three years to maturity. If you round the bond’s intrinsic value to the nearest whole dollar, then its intrinsic value of (rounded to the nearest whole dollar) is its par value, so that the bond is .
Given your computation and conclusions, which of the following statements is true?
When the coupon rate is less than Amelia’s required return, the bond should trade at a discount.
A bond should trade at par when the coupon rate is less than Amelia’s required return.
When the coupon rate is less than Amelia’s required return, the intrinsic value will be greater than its par value.
When the coupon rate is less than Amelia’s required return, the bond should trade at a premium.
• When the bond’s coupon rate is equal to the
bondholder’s required return, the bond’s intrinsic value will equal
its par value, and the bond will trade at par.
• When the bond’s coupon rate is greater than the
bondholder’s required return, the bond’s intrinsic value will trade
above/higher its par value, and the bond will trade at a
premium.
• When the bond’s coupon rate is less than the
bondholder’s required return, the bond’s intrinsic value will be
less than its par value, and the bond will trade at discount .
A Semiannual interest/coupon
payment=1000*9%/2=45
B $1,000
C Semiannual required
return=9%/2=4.5%
Based on this equation and the data, it is reasonable to expect
that Amelia’s potential bond investment is currently exhibiting an
intrinsic value equal to $1,000.
Now, consider the situation in which Amelia wants to earn a return of 12%, but the bond being considered for purchase offers a coupon rate of 9.00%. Again, assume that the bond pays semiannual interest payments and has three years to maturity. If you round the bond’s intrinsic value to the nearest whole dollar, then its intrinsic value of 926.2401351 (Price=1000*9%/12%*(1-1/1.06^6)+1000/1.06^6=926.2401351) is less than its par value, so that the bond is trading at discount.
When the coupon rate is less than Amelia’s required return, the
bond should trade at a discount.
