value. Consequently, most of our examples and problems throughout this text
will focus on bonds with fixed coupon rates.
In some cases, however, a bond’s coupon payment will vary over time. These
floating rate bonds work as follows. The coupon rate is set for, say, the initial
six-month period, after which it is adjusted every six months based on some
market rate. Some corporate issues are tied to the Treasury bond rate, while
other issues are tied to other rates. Many additional provisions can be included
in floating rate issues. For example, some are convertible to fixed rate debt,
whereas others have upper and lower limits (“caps” and “floors”) on how high
or low the rate can go.
Floating rate debt is popular with investors who are worried about the risk of
rising interest rates, since the interest paid increases whenever market rates rise.
This causes the market value of the debt to be stabilized, and it also provides in-
stitutional buyers such as banks with income that is better geared to their own
obligations. Banks’ deposit costs rise with interest rates, so the income on float-
ing rate loans that they have made rises at the same time their deposit costs are
rising. The savings and loan industry was virtually destroyed as a result of their
practice of making fixed rate mortgage loans but borrowing on floating rate
terms. If you are earning 6 percent but paying 10 percent—which they were—
you soon go bankrupt—which they did.
Moreover, floating rate debt appeals to corporations that want to issue long-
term debt without committing themselves to paying an historically high interest
rate for the entire life of the loan.
Some bonds pay no coupons at all, but are offered at a substantial discount
below their par values and hence provide capital appreciation rather than inter-
est income. These securities are called zero coupon bonds (“zeros”). Other
bonds pay some coupon interest, but not enough to be issued at par. In general,
any bond originally offered at a price significantly below its par value is called
an original issue discount (OID) bond. Corporations first used zeros in a
major way in 1981. In recent years IBM, Alcoa, JCPenney, ITT, Cities Service,
GMAC, Lockheed Martin, and even the U.S. Treasury have used zeros to raise
billions of dollars. Some of the details associated with issuing or investing in
zero coupon bonds are discussed more fully in Appendix 8A.
MATURITY DATE
Bonds generally have a specified maturity date on which the par value must be
repaid. Allied’s bonds, which were issued on January 3, 2002, will mature on
January 2, 2017; thus, they had a 15-year maturity at the time they were issued.
Most bonds have original maturities (the maturity at the time the bond is is-
sued) ranging from 10 to 40 years, but any maturity is legally permissible.

Of
course, the effective maturity of a bond declines each year after it has been is-
sued. Thus, Allied’s bonds had a 15-year original maturity, but in 2003, a year
later, they will have a 14-year maturity, and so on.
KEY CHARACTERISTICS OF BONDS
Zero Coupon Bond
A bond that pays no annual
interest but is sold at a discount
below par, thus providing
compensation to investors in the
form of capital appreciation.
Original Issue Discount Bond
Any bond originally offered at a
price below its par value.
Maturity Date
A specified date on which the par
value of a bond must be repaid.
Original Maturity
The number of years to maturity
at the time a bond is issued.

In July 1993, Walt Disney Co., attempting to lock in a low interest rate, issued the first 100-year
bonds to be sold by any borrower in modern times. Soon after, Coca-Cola became the second com-
pany to stretch the meaning of “long-term bond” by selling $150 million worth of 100-year bonds.
Floating Rate Bond
A bond whose interest rate
fluctuates with shifts in the
general level of interest rates.
