B. Bond Values and Yields
The cash flows from a bond are the coupons and the face value.
The value of a bond (market price) is the present value of the
expected cash flows discounted at the market rate of interest.
Yield to maturity (YTM) – the required market rate or return, or
rate that makes the discounted cash flows from a bond equal to the
bond’s market price.
Real World Tip: Not all bond interest is paid in cash. Isle of Arran
Discount bond – a bond that sells for less than its par value. This is
the case when the YTM is greater than the coupon rate.
Example: Suppose the YTM on bonds similar to that of Wilhite
Co. (see the previous example) is 13% instead of 11%. What is the
bond price?

C. Interest Rate Risk
Real-World Tip: In 1998, newscasters frequently referred to rates
reaching historic lows. As a refresher, the lowest rate in 1998 on
10-year Treasuries (monthly, annualized returns for the constant
maturity index) was 4.53%. Rates increased after that point and
then fell to a low of 3.33% in June of 2003 and rebounded some to
4.10% in October of 2004 (still below the “historic lows” in
1998!)

Real-World Tip: Upon learning the concept of interest rate risk,
students sometimes conclude that bonds with low interest-rate risk
(i.e. high coupon bonds) are necessarily “safer” than otherwise
identical bonds with lower coupons. In reality, the contrary may be
You may wish to point out that one potentially undesirable feature
of high-coupon bonds is the required reinvestment of coupons at
the computed yield-to-maturity if one is to actually earn that yield.
D. Finding the Yield to Maturity: More Trial and Error
It is a trial and error process to find the YTM via the general
formula above. Knowing if a bond sells at a discount (YTM >
coupon rate) or premium (YTM < coupon rate) is a help, but using
a financial calculator is by far the quickest, easiest, and most
accurate method.
Chapter 07 - Interest Rates and Bond Valuation
Lecture Tip: Students should understand that finding the yield to
maturity is a tedious process of trial and error. It may help to pose
Lecture Tip: You may wish to discuss the components of required
returns for bonds in a fashion analogous to the stock return
discussion in the next chapter. As with common stocks, the
required return on a bond can be decomposed into current income
and capital gains components. The yield-to-maturity (YTM) equals
the current yield plus the capital gains yield.
The capital gains yield equals the change in bond price divided by
the initial outlay. Given no change in market rates, the “one-year-
later” price must be $1,065.65. Therefore, the capital gains yield
is (1,065.65 – 1,080.42) / 1,080.42 = -.0137 = -1.37%. Summing,
the YTM = 5.55% - 1.37% = 4.18% (slight difference due to

7.4. Some Different Types of Bonds
A. Government Bonds
Long-term debt instruments issued by a governmental entity.
Treasury bonds are bonds issued by a federal government; a state
or local government issues municipal bonds. In the U.S.,
Treasuries are exempt from state taxation and “munis” are exempt
from federal taxation.

D. Other Types of Bonds
Income bonds – coupon is paid if income is sufficient
Convertible bonds – can be traded for a fixed number of shares of
stock
Put bonds – shareholders can redeem for par at their discretion
Real World Tip: Near the end of the 1990s, firms began issuing
bonds that have come to be known as “death puts” because they
are designed to appeal to investors approaching their own demise.
