CHAPTER 6 – Valuing Bonds
Questions
LG1 1. What does a call provision allow the issuer to do, and why would they do it?
A call provision on a bond issue allows the issuer to pay off the bond debt early at a cost
of the principal plus any call premium. Most of the time a bond issuer is called, it is
because interest rates have substantially declined in the economy. The issuer calls the
existing bonds and issues new bonds at the lower interest rate. This reduces the interest
payments the issuer must pay each year.
LG2 2. List the differences between the new TIPS and traditional Treasury bonds.
Traditional Treasury bonds have a fixed principal and constant payments. Because the
principal and coupon rate are fixed, interest rate changes in the economy cause the market
price of the bonds to have large fluctuations. On the other hand, the principal of a TIPS
increases with the rate of inflation. Similar to a T-bond, the TIPS has a constant coupon
rate. However, since the principal of the TIPS increases over time, the interest payment
increases over time. This inflation rate adjustment of a TIPS’ principal every six months
reduces the amount of downward price change in the price of the bond when interest rates
increase.
LG2 3. Explain how mortgage-backed securities work.
A large amount of home mortgages are purchased and pooled together. The home owners
pay interest and principal monthly on their mortgages. Bonds are issued from the pool of
mortgages, using the mortgages as collateral. The interest payments and bond principal
payments for these mortgage-backed securities (MBS) originate from the mortgage
borrowers and flow through the pool of mortgages. As the home owners pay off their
mortgages over time, the MBS are also paid.
LG3 4. Provide the definitions of a discount bond and a premium bond. Give examples.
A discount bond is simply a bond that is selling below its par value. It would be quoted at
a price that is less than 100 percent of par, like 99.05. A premium bond is a bond selling
above its par value. Its price will be quoted as over 100 percent of par value, like 101.15.
A bond becomes a discount bond when market interest rates rise above the bond’s coupon
rate. A bond becomes a premium bond when market interest rates fall below the bond’s
coupon rate.
LG4 5. Describe the differences in interest payments and bond price between a 5 percent
coupon bond and a zero coupon bond.
7-1
Chapter 6, Solutions
Cornett, Adair, and Nofsinger
The 5 percent coupon bond pays annual interest of 5 percent of the bond’s par value. For
$1,000 par value bond, this would be $50 per year. This interest might be paid in two
payments of $25. The price of the coupon bond tends to stay near its par value. The zero
coupon bond pays no interest payments. The bondholder earns a return from the increase
of the bond’s market price over time. The bond’s price is initially much lower than its par
value. When the zero coupon bond finally matures, the par value is paid.
LG5 6. All else equal, which bond’s price is more affected by a change in interest rates, a
short-term bond or a longer-term bond? Why?
All else equal, a long-term bond experiences larger price changes when interest rates
change than a short-term bond. A bond’s price is the present value of all its cash flows.
Changes in the discount rate (the interest rate) impact present values more for cash flows
that are further out in time.
LG5 7. All else equal, which bond’s price is more effected by a change in interest rates, a bond
with a large coupon or a small coupon? Why?
The price of the bond with the small coupon will be impacted more by a change in interest
rates than the price of the large coupon bond. For a small coupon bond, the cash flows are
weighted much more toward the maturity date because of the small interest payments.
The large coupon bond has high interest payments, many occur soon. These higher cash
flows made earlier dampen the impact of interest rate changes because those changes in
the discount rate impact the earlier cash flows to a lesser degree than the later cash flows.
LG5 8. Explain how a bond’s interest rate can change over time even if interest rates in the
economy do not change.
Because of the yield curve, there are different interest rates that apply to each time to
maturity. So, as a bond gets closer to its maturity date, different interest rates may apply
to its discounting even when interest rates in the economy have not changed.
LG6 9. Compare and contrast the advantages and disadvantages of the current yield
computation versus yield to maturity calculations.
The current yield computation is useful because it is a very simple one. It provides a quick
and easy assessment of what the bond offers the investor in return. But it measures only
the return from the interest rate payments. The full return to an investor also includes the
capital gain or loss the bond will experience if it is selling as a discount or premium bond.
The yield to maturity computation is more difficult, but it incorporates the full return the
bond offers to investors.
LG6 10. What is the yield to call and why is it important to a bond investor?
7-2
Chapter 6, Solutions
Cornett, Adair, and Nofsinger
Many bonds do not survive until their maturity date because they get paid early through a
call provision. The yield to call is the yield that would be earned if the bond is purchased
at today’s price and held until it is called by the issuer. The computation incorporates the
additional call premium that is paid with the principal.
LG6 11. What is the purpose of computing the equivalent taxable yield of a municipal bond?
Municipal bonds offer a tax advantage for the bondholder that other kinds of bonds do not
offer. Thus, their yield to maturity is not directly comparable to that of other bonds. The
equivalent taxable yield (ETY) is an adjustment to the yield to make it comparable to
taxable bonds. Bond investors can use the ETY to assess which bond will earn them a
higher after-tax return.
LG6 12. Explain why high income and wealthy people are more likely to buy a municipal bond
than a corporate bond.
Individual bondholders do not owe taxes on interest payments received from municipal
bonds. This tax advantage is more valuable to individuals who are in a higher marginal tax
bracket. Because wealth individuals are usually in a higher tax bracket, this tax advantage
is more valuable to them.
LG7 13. Why does a Treasury bond offer a lower yield than a corporate bond with the same
time to maturity? Could a corporate bond with a different time to maturity offer a lower
yield? Explain.
The Treasury bond has lower credit risk than the corporate bond. Given the risk/return
relationship, lower risk is associated with lower expected return. Thus, all else equal, a
Treasury bond will offer a lower yield to maturity than a corporate bond. However, if the
yield curve slopes upward, then shorter term to maturity bonds will require a smaller
interest rate than longer term bonds. So, it is possible that a short-term corporate bond
would offer a lower yield than a long-term Treasury bond.
LG7 14. Describe the difference between a bond issued as a high-yield bond and one that has
become a “fallen angel.”
Both of these bonds would be rated as BB or below. The company referred to as a fallen
angel would be a firm that was a successful, financially stable firm that has recently
struggled. Many of the bondholders had purchased the bond when it was rated much
better. The other company issued bonds when it was already in a less financially stable
condition. The purchasers of these bonds bought the bonds while they were rated as a
junk bond.
LG8 15. What is the difference in the trading volume between Treasury bonds and corporate
bonds? Give examples and/or evidence.
7-3
Chapter 6, Solutions
Cornett, Adair, and Nofsinger
There is high trading volume in Treasury bonds and low volume in corporate bonds.
LG8 16. Explain how the Lehman Brothers Intermediate Bond Index might increase one day
while the Merrill Lynch High Yield Index decreases the same day.
These two indices use different bonds. This Lehman index uses Treasury bonds with
medium terms to maturity. The Merrill Lynch index uses high risk bonds. When
investors determine that there is more risk in the economy, the spread between the safer
bonds (Treasuries) and riskier bonds (high yield) widen. If risk in the economy is
perceived to be declining, this spread will decrease. This question is an example of the
spread widening.

The end-of-year interest payment was: ½ × 3.5% × 201.3/185.6 × $1,000 = $18.98
Total dollar return = $27.48 + $18.82 + $18.98 = $65.28

6-34 TIPS Total Return Reconsider the 2.25% TIPS discussed in problem 6-20. It was
issued with CPI reference of 183.5. The bond is purchased at the beginning of the year
(after the interest payment), when the CPI was 197.1. For the interest payment in the
middle of the year, the CPI was 200.1. Now, at the end of the year, the CPI is 203.8 and
the interest payment has been made. What is the total return of the TIPS in dollars and in
percentage terms for the year?
gain = end of year value – beginning of year value =
203.8/183.5 × $1,000 − 197.1/183.5 × $1,000 = $1,110.63 − $1,074.11 = $36.52
The mid-year interest payment was: ½ × 2.25% × 200.1/183.5 × $1,000 = $12.27
The end-of-year interest payment was: ½ × 2.25% × 203.8/183.5 × $1,000 = $12.49
Total dollar return = $36.52 + $12.27 + $12.49 = $61.28
As a percentage, the return was = $61.28 ÷ $1,074.11 = 5.71%

6-37 Yields of a Bond A 3.75 percent coupon municipal bond has 14 years left to
maturity and has a price quote of 98.45. The bond can be called in 4 years. The call

yield to maturity, taxable equivalent yield (for an investor in the 35 percent marginal tax
bracket), and yield to call. (Assume interest payments are paid semi-annually and a par

6-41 Excel Problem Say that in June of 2008, a company issued bonds that are scheduled
to mature in June of 2011. The coupon rate is 5.75% and is paid semi-annually. The bond
issue was rated AAA.
A. Build a spreadsheet that shows how much money the firm pays for each interest rate
payment and when those payments will occur if the bond issue sells 50,000 bonds.
B. If the bond issue rating would have been BBB, then the coupon rate would have been
6.30%. Show the interest payments with this rating. Explain why bond ratings are
important to firms issuing capital debt.
C. Consider that interest rates in the economy increased in the first half of 2008. If the
firm would have issued the bonds in January of 2008, then the interest rates would have
only been 5.40%. How much extra money per year is the firm paying because it issued
the bonds in June instead of January?

Suppose that the firm Treasure Toys makes an announcement that they are purchasing
Land’o’Toys. Due to Treasury Toy’s projected financial structure after the purchase,
Standard & Poors states that the bond rating Land’o’Toys bonds will change to BB.
A. Compute the yield to maturity of Land’o’Toys bonds before the purchase
announcement and us it to determine the likely bond rating.
B. Assume the bond’s price changes to reflect the new credit rating. What is the new
price? Did the price increase or decrease?
C. What is the dollar change and percentage change in the bond price?
D. How do the bond investors feel about the announcement?
SOLUTION: A. YTM: N=20, PV=-1,037.19, PMT=32.50, FV=1000 CPT I = 3.00%, YTM =
3.00% × 2 = 6.00%
This bond is likely rated as an “A”.
B. The new YTM will likely be 7.3% annually, so the price will change to:
N=20, I=3.65, PMT=32.50, FV=1000 CPT PV = -943.91
The price decreased because it got riskier.
C. The price change would be $943.91 − $1,037.19 = -$93.28
The change as a percentage would be -$93.28 ÷ $1,037.19 = -8.99%
D. In a firm buyout, the stock holders of the target firm earn a nice profit. However,
the bondholders of the target firm can be unhappy if the new combined firm has a
worse bond rating, like in this case.
