Bond Valuation
INSTRUCTOR’S RESOURCES
Overview
This chapter begins with a thorough discussion of interest rates, yield curves, and their relationship to required
returns. Features of the major types of bond issues are presented along with their legal issues, risk characteristics,
and indenture convents. The chapter then introduces students to the important concept of valuation and
demonstrates the impact of cash flows, timing, and risk on value. It explains models for valuing bonds and the
calculation of yield-to-maturity using either the trial-and-error approach or the approximate yield formula.

ANSWERS TO REVIEW QUESTIONS
6-1
The real rate of interest is the rate which creates an equilibrium between the supply of savings and demand
for investment funds. The nominal rate of interest is the actual rate of interest charged by the supplier and
paid by the demander. The nominal rate of interest differs from the real rate of interest due to two factors:
(1) a premium due to inflationary expectations (IP) and (2) a premium due to issuer and issue characteristic
risks (RP). The nominal rate of interest for a security can be defined as k1 = k* + IP + RP. For a threemonth U.S. Treasury bill, the nominal rate of interest can be stated as k1 = k* + IP. The default risk
premium, RP, is assumed to be zero since the security is backed by the U.S. government; this security is
commonly considered the risk-free asset.
6-2
The term structure of interest rates is the relationship of the rate of return to the time to maturity for any
class of similar-risk securities. The graphic presentation of this relationship is the yield curve.
6-3
For a given class of securities, the slope of the curve reflects an expectation about the movement of interest
rates over time. The most commonly used class of securities is U.S. Treasury securities.
a. Downward sloping: long-term borrowing costs are lower than short-term borrowing costs.
b. Upward sloping: Short-term borrowing costs are lower than long-term borrowing costs.
c. Flat: Borrowing costs are relatively similar for short- and long-term loans.
The upward-sloping yield curve has been the most prevalent historically.
6-4
a. According to the expectations theory, the yield curve reflects investor expectations about future interest
rates, with the differences based on inflation expectations. The curve can take any of the three forms.
An upward-sloping curve is the result of increasing inflationary expectations, and vice versa.
b. The liquidity preference theory is an explanation for the upward-sloping yield curve. This theory states
that long-term rates are generally higher than short-term rates due to the desire of investors for greater
liquidity, and thus a premium must be offered to attract adequate long-term investment.
c. The market segmentation theory is another theory which can explain any of the three curve shapes.
Since the market for loans can be segmented based on maturity, sources of supply and demand for loans
within each segment determine the prevailing interest rate. If supply is greater than demand for shortterm funds at a time when demand for long-term loans is higher than the supply of funding, the yield
curve would be upward-sloping. Obviously, the reverse also holds true.

scheduled.
The possibility that the issuer will not pay the contractual interest or principal as
¾ Maturity (interest rate) risk: The possibility that changes in the interest rates on similar securities will
cause the value of the security to change by a greater amount the longer its maturity, and vice versa.

Chapter 6 Interest Rates and Bond Valuation
¾ Liquidity risk: The ease with which securities can be converted to cash without a loss in value.
¾ Contractual provisions: Covenants included in a debt agreement or stock issue defining the rights and
restrictions of the issuer and the purchaser. These can increase or reduce the risk of a security.
¾ Tax risk: Certain securities issued by agencies of state and local governments are exempt from federal,
and in some cases state and local, taxes, thereby reducing the nominal rate of interest by an amount
which brings the return into line with the after-tax return on a taxable issue of similar risk.
The risks that are debt-specific are default, maturity, and contractual provisions.
6-6
Most corporate bonds are issued in denominations of $1,000 with maturities of 10 to 30 years. The stated
interest rate on a bond represents the percentage of the bond's par value that will be paid out annually,
although the actual payments may be divided up and made quarterly or semi-annually.
Both bond indentures and trustees are means of protecting the bondholders. The bond indenture is a
complex and lengthy legal document stating the conditions under which a bond is issued. The trustee may
be a paid individual, corporation, or commercial bank trust department that acts as a third-party "watch dog"
on behalf of the bondholders to ensure that the issuer does not default on its contractual commitment to the
bondholders.
6-7
Long-term lenders include restrictive covenants in loan agreements in order to place certain operating and/or
financial constraints on the borrower. These constraints are intended to assure the lender that the borrowing
firm will maintain a specified financial condition and managerial structure during the term of the loan. Since
the lender is committing funds for a long period of time, he seeks to protect himself against adverse financial
developments that may affect the borrower. The restrictive provisions (also called negative covenants)
differ from the so-called standard debt provisions in that they place certain constraints on the firm's
operations, whereas the standard provisions (also called affirmative covenants) require the firm to operate in
a respectable and businesslike manner. Standard provisions include such requirements as providing audited
financial statements on a regular schedule, paying taxes and liabilities when due, maintaining all facilities in
good working order, and keeping accounting records in accordance with GAAP.
Violation of any of the standard or restrictive loan provisions gives the lender the right to demand immediate
repayment of both accrued interest and principal of the loan. However, the lender does not normally
demand immediate repayment but instead evaluates the situation in order to determine if the violation is
serious enough to jeopardize the loan. The lender's options are: Waive the violation, waive the violation and
renegotiate terms of the original agreement, or demand repayment.
6-8
Short-term borrowing is normally less expensive than long-term borrowing due to the greater uncertainty
associated with longer maturity loans. The major factors affecting the cost of long-term debt (or the interest
rate), in addition to loan maturity, are loan size, borrower risk, and the basic cost of money.
6-9
If a bond has a conversion feature, the bondholders have the option of converting the bond into a certain
number of shares of stock within a certain period of time. A call feature gives the issuer the opportunity to
repurchase, or call, bonds at a stated price prior to maturity. It provides extra compensation to bondholders
for the potential opportunity losses that would result if the bond were called due to declining interest rates.
This feature allows the issuer to retire outstanding debt prior to maturity and, in the case of convertibles, to

force conversion. Stock purchase warrants, which are sometimes included as part of a bond issue, give the
holder the right to purchase a certain number of shares of common stock at a specified price.
Bonds are rated by independent rating agencies such as Moody's and Standard & Poor's with respect to their
overall quality, as measured by the safety of repayment of principal and interest. Ratings are the result of
detailed financial ratio and cash flow analyses of the issuing firm. The bond rating affects the rate of return
on the bond. The higher the rating, the less risk and the lower the rate.
6-10
The bond quotation for corporate bonds includes six pieces of information of interest to the investor. It
includes the name of the issuer, the coupon rate, the year of maturity, the volume of bonds traded for the
reporting day, the trading price for the last trade of the day (called the close price), and the change in the last
trading price from the preceding trading day. The closing price and the change in price are quoted as a
percent of the maturity value of the bond.
6-11
Eurobonds are bonds issued by an international borrower and sold to investors in countries with currencies
other than that in which the bond is denominated. For example, a dollar-denominated Eurobond issued by
an American corporation can be sold to French, German, Swiss, or Japanese investors. A foreign bond, on
the other hand, is issued by a foreign borrower in a host country's capital market and denominated in the host
currency. An example is a French-franc denominated bond issued in France by an English company.
6-12
A financial manager must understand the valuation process in order to judge the value of benefits received
from stocks, bonds, and other assets in view of their risk, return, and combined impact on share value.
6-13
Three key inputs to the valuation process are:
1. Cash flows - the cash generated from ownership of the asset;
2. Timing - the time period(s) in which cash flows are received; and
3. Required return - the interest rate used to discount the future cash flows to a present value. The
selection of the required return allows the level of risk to be adjusted; the higher the risk, the higher the
required return (discount rate).
6-14
The valuation process applies to assets that provide an intermittent cash flow or even a single cash flow over
any time period.
6-15
The value of any asset is the present value of future cash flows expected from the asset over the relevant
time period. The three key inputs in the valuation process are cash flows, the required rate of return, and the
timing of cash flows. The equation for value is:

dollar par value
required return on the bond
To find the value of bonds paying interest semiannually, the basic bond valuation equation is adjusted as
follows to account for the more frequent payment of interest:
1. The annual interest must be converted to semiannual interest by dividing by two.
2. The number of years to maturity must be multiplied by two.
3. The required return must be converted to a semiannual rate by dividing it by 2.
6-17
A bond sells at a discount when the required return exceeds the coupon rate. A bond sells at a premium
when the required return is less than the coupon rate. A bond sells at par value when the required return
equals the coupon rate. The coupon rate is generally a fixed rate of interest, whereas the required return
fluctuates with shifts in the cost of long-term funds due to economic conditions and/or risk of the issuing
firm. The disparity between the required rate and the coupon rate will cause the bond to be sold at a
discount or premium.
6-18
If the required return on a bond is constant until maturity and different from the coupon interest rate, the
bond's value approaches its $1,000 par value as the time to maturity declines.
6-19
To protect against the impact of rising interest rates, a risk-averse investor would prefer bonds with short
periods until maturity. The responsiveness of the bond's market value to interest rate fluctuations is an
increasing function of the time to maturity.
6-20
The yield-to-maturity (YTM) on a bond is the rate investors earn if they buy the bond at a specific price and
hold it until maturity. The trial-and-error approach to calculating the YTM requires finding the value of the
bond at various rates to determine the rate causing the calculated bond value to equal its current value. The
approximate approach for calculating YTM uses the following equation:

The YTM can be found precisely by using a hand-held financial calculator and using the time value
functions. Enter the B0 as the present value, the I as the annual payment, and the n as the number of periods
until maturity. Have the calculator solve for the interest rate. This interest value is the YTM. Many
calculators are already programmed to solve for the Internal Rate of Return (IRR). Using this feature will
also obtain the YTM since the YTM and IRR are determined the same way.

Followers of the liquidity preference theory would state that the upward sloping shape of the curve is due to
the desire by lenders to lend short-term and the desire by business to borrow long term. The dashed line in
the part c graph shows what the curve would look like without the existence of liquidity preference, ignoring
the other yield curve theories.
e.
Market segmentation theorists would argue that the upward slope is due to the fact that under current
economic conditions there is greater demand for long-term loans for items such as real estate than for shortterm loans such as seasonal needs.

The maximum price Laura should pay is $13,032. Unable to assess the risk, Laura would use the most
conservative price, therefore assuming the highest risk.
c.
By increasing the risk of receiving cash flow from an asset, the required rate of return increases, which
reduces the value of the asset.

Bo = I x (PVIFAkd%,n) + M x (PVIFkd%,n)
Bo = 120 x (PVIFA10%,16) + M x (PVIF10%,16)
Bo = $120 x (7.824) + $1,000 x (.218)
Bo = $938.88 + $218
Bo = $1,156.88

Since Complex Systems' bonds were issued, there may have been a shift in the supply-demand relationship
for money or a change in the risk of the firm.
c.
Bo = I x (PVIFAkd%,n) + M x (PVIFkd%,n)
Bo = 120 x (PVIFA12%,16) + M x (PVIF12%,16)

When the required return is equal to the coupon rate, the bond value is equal to the par value. In contrast to
a. above, if the required return is less than the coupon rate, the bond will sell at a premium (its value will be
greater than par).

When the required return is less than the coupon rate, the market value is greater than the par value and the
bond sells at a premium. When the required return is greater than the coupon rate, the market value is less
than the par value; the bond therefore sells at a discount.
d.
The required return on the bond is likely to differ from the coupon interest rate because either (1) economic
conditions have changed, causing a shift in the basic cost of long-term funds, or (2) the firm's risk has
changed.

The greater the length of time to maturity, the more responsive the market value of the bond to changing
required returns, and vice versa.
If Lynn wants to minimize interest rate risk in the future, she would choose Bond A with the shorter
maturity. Any change in interest rates will impact the market value of Bond A less than if she held Bond B.

e.
The difference is due to the differences in interest payments received each year. The principal payments at
maturity will be the same for both bonds. Using the calculator, the yield to maturity of bond A is 11.77%
and the yield to maturity of bond B is 11.59% with the 10% reinvestment rate for the interest payments.
Mark would be better off investing in bond A. The reasoning behind this result is that for both bonds the
principal is priced to yield the YTM of 12%. However, bond B is more dependent upon the reinvestment of
the large coupon payment at the YTM to earn the 12% than is the lower coupon payment of A.

CHAPTER 6 CASE
Evaluating Annie Hegg’s Proposed Investment in Atilier Industries Bonds
This case demonstrates how a risky investment can affect a firm's value. First, students must calculate the current
value of Suarez's bonds and stock, rework the calculations assuming that the firm makes the risky investment, and
then draw some conclusions about the value of the firm in this situation. In addition to gaining experience in
valuation of bonds and stock, students will see the relationship between risk and valuation.
a.
Annie should convert the bonds. The value of the stock if the bond is converted is:
50 shares x $30 per share = $1,500
while if the bond was allowed to be called in the value would be on $1,080
b
Current value of bond under different required returns – annual interest
(1)
Bo = I x (PVIFA6%,25 yrs.) + M x (PVIF 6%,25 yrs.)
Bo = $80 x (12.783) + $1,000 x (.233)
Bo = $1,022.64 + $233
Bo = $1,255.64
Ca1culator solution: $1,255.67
The bond would be at a premium.
(2)
Bo = I x (PVIFA8%,25 yrs.) + M x (PVIF8%,25 yrs.)
Bo = $80 x (10.674) + $1,000 x (.146)
Bo = $853.92 + $146
Bo = $999.92
Ca1culator solution: $1,000.00
The bond would be at par value..
(3)
Bo = I x (PVIFA10%,25 yrs.) + M x (PVIF10%,25 yrs.)
Bo = $80 x (9.077) + $1,000 x (.092)
Bo = $726.16 + $92
Bo = $818.16
Ca1culator solution: $818.46
The bond would be at a discount.

Bo = $1,257.20
Ca1culator solution: $1,257.30
The bond would be at a premium.
(2)
Bo = I x (PVIFA4%,50 yrs.) + M x (PVI4%,50 yrs.)
Bo = $40 x (21.482) + $1,000 x (.141)
Bo = $859.28 + $146
Bo = $1005.28
Ca1culator solution: $1,000.00
The bond would be at par value..
(3)
Bo = I x (PVIFA5%,50 yrs.) + M x (PVIF5%,50 yrs.)
Bo = $40 x (18.256) + $1,000 x (.087)
Bo = $730.24 + $87
Bo = $817.24
Ca1culator solution: $817.44
The bond would be at a discount.
Under all 3 required returns for both annual and semiannual interest payments the bonds are consistent in their
direction of pricing. When the required return is above (below) the coupon the bond sells at a discount (premium).
When the required return and coupon are equal the bond sells at par. When the change is made from annual to
semiannual payments the value of the premium and par value bonds increase while the value of the discount bond
decreases. This difference is due to the higher effective return associated with compounding frequency more often
than annual.
d.
If expected inflation increases by 1% the required return will increase from 8% to 9%, and the bond price
would drop to $908.84. This amount is the maximum Annie should pay for the bond.
Bo = I x (PVIFA9%,25 yrs.) + M x (PVIF9%,25 yrs.)
Bo = $80 x (9.823) + $1,000 x (.116)
Bo = $785.84 + $123
Bo = $908.84
Ca1culator solution: $901.77
e.
The value of the bond would decline to $925.00 due to the higher required return and the inverse
relationship between bond yields and bond values.
Bo = I x (PVIFA8.75%,25 yrs.) + M x (PVIF8.75%,25 yrs.)
Bo = $80 x (10.025) + $1,000 x (.123)
Bo = $802.00 + $123
Bo = $925.00
Ca1culator solution: $924.81
f.
The bond would increase in value and a gain of $110.88 would be earned by Annie.

The bond is more sensitive to interest rate changes when the time to maturity is longer (22 years) than when
the time to maturity is shorter (15 years). Maturity risk decreases as the bond gets closer to maturity.
h.
Using the calculator the YTM on this bond assuming annual interest payments of $80, 25 years to maturity,
and a current price of $983.75 would be 8.15%.
i.
Annie should probably not invest in the Atilier bond. There are several reasons for this conclusion.
1.
The term to maturity is long and thus the maturity risk is high.
2.
An increase in interest rates is likely due to the potential downgrading of the bond thus driving the
price down.
3.
An increase in interest rates is likely due to the possibility of higher inflation thus driving the price
down.
4.
The price of $983.75 is well above her minimum price of $908.84 assuming an increase in interest
rates of 1%.
