Bond Basics
 Bonds are simply long-term IOUs that represent
claims against a firm’s assets.
 Bonds are a form of debt
 Bonds are often referred to as fixed-income
investments.
2
Key Features of a Bond
 Debt instrument issued by a corp. or government.
3
Key Features of a Bond
 Par value = face amount of the bond, which is paid at
maturity (assume $1,000).
=
4
Key Features of a Bond
 Coupon rate – stated interest rate (generally fixed)
paid by the issuer. Multiply by par to get dollar
payment of interest.
5
Key Features of a Bond
 Maturity date – when the bond must be repaid.
 Yield to maturity - rate of return earned on a bond
held until maturity.
6
What is interest rate risk?
 Interest rate risk is the concern that interest rates will
change, and therefore, a reduction in the value/price
of a security.
7
Interest rate risk example
Suppose you just inherited $500,000. You intend to
invest the money and live off the interest.
8
Interest rate risk example
 You may invest in either a:
 10-year bond
 series of ten 1-year bonds
 Both bonds currently yield 5%.
9
 If you choose the 1-year bond strategy:
 After year 1, you receive $25,000 in
income and have $500,000 to reinvest.
But, if 1-year rates fall to 3%, your
annual income would fall to $15,000.
 If you choose the 10-year bond strategy:
 You can lock in a 5% interest rate, and
$25,000 annual income.
10
Interest Rate Risk
 Price Risk
 Change in price due to changes in interest
rates
 Long-term bonds have more price risk
than short-term bonds
 Low coupon rate bonds have more price
risk than high coupon rate bonds
11
12
Bond Value
 Bond Value = PV(coupons) + PV(par)
 Bond Value = PV(annuity) + PV(lump sum)
 Remember:
 As interest rates increase present values decrease
 ( r → PV  )
 As interest rates increase, bond prices decrease
and vice versa

Most Bonds Pay Interest Semi-Annually:
What is the value of a bond with a semi-annual
coupon with 5 years to maturity, 9% (nominal)
coupon rate if an investor desires a 10% (nominal)
return?
18
Most Bonds Pay Interest Semi-Annually:
e.g. semiannual coupon bond with 5 years
to maturity, 9% annual coupon rate.
Instead of 5 annual payments of $90, the bondholder
receives 10 semiannual payments of $45.

Types of Bonds
 Vanilla – fixed coupons, repaid at maturity
 Zero Coupon – pay no explicit interest but instead, sell
at a deep discount
 Convertible – can be converted into to stock
33
Types of Bonds
 Junk Bonds – below investment grade
34
Government Bonds
 Treasury Securities = Federal government debt
 Treasury Bills (T-bills)
 Pure discount bonds
 Original maturity of one year or less
 Treasury notes (T-notes)
 Coupon debt
 Original maturity between one and ten years
 Treasury bonds (T-bonds)
 Coupon debt

Original maturity greater than ten years
35
Tax Consequences
A taxable bond has a yield of 8% and a
municipal bond has a yield of 6%
 If you are in a 40% tax bracket, which bond do
you prefer?
 8%(1 - .4) = 4.8%
 The after-tax return on the corporate bond is 4.8%,
compared to a 6% return on the municipal
 At what tax rate would you be indifferent
between the two bonds?
 8%(1 – T) = 6%
 T = 25%
36
Bond Ratings
 Moody’s , Standard & Poor’s and Fitch regularly
monitor issuer’s financial condition and assign a
rating to the debt

 High Grade
 Moody’s Aaa and S&P AAA – capacity to pay is extremely

 Moody’s Aa and S&P AA – capacity to pay is very strong
 Medium Grade
 Moody’s A and S&P A – capacity to pay is strong, but
more susceptible to changes in circumstances
 Moody’s Baa and S&P BBB – capacity to pay is adequate,
adverse conditions will have more impact on the firm’s
ability to pay
38
Bond Ratings - Speculative
 Low Grade
 Moody’s Ba, B, Caa and Ca
 S&P BB, B, CCC, CC
 Considered speculative with respect to capacity
to pay. The “B” ratings are the lowest degree
of speculation.
 Very Low Grade
 Moody’s C and S&P C – income bonds with no
interest being paid
 Moody’s D and S&P D – in default with principal
and interest in arrears

What is the “term structure of interest rates”?
What is a “yield curve”?
 Term structure: the relationship between
interest rates (or yields) and maturities.
 A graph of the term structure is called the yield
curve.

 This constructed yield curve is upward

 This is due to increasing expected inflation

Default risk
 If an issuer defaults, investors receive less than

 Influenced by the issuer’s financial strength and
