The Bond Contract
A bond normally represents a long term contractual obligation of the firm to pay interest to the bondholder as well as the face value of the bond at maturity.
Par value is the face value of the bond. Coupon rate is the actual rate on the bond. Zero-Coupon bonds are deep discount bonds which
compensate the investor through capital appreciation. Maturity date is the date on which the par value is paid.
Serial payment under which bonds are paid off in installments over the life of the issue.

Bond Indenture
A bond indenture is a legal document which covers the major provisions in a bond agreement, administered by an independent trustee. Sinking Fund Provision
Call Provision
Put Provision
5
Secured Bonds
A mortgage bond is backed by real property
pledged as a collateral.
Equipment trust certificates are used by firms in
the transportation industry.
Proceeds from the sale of certificates are used to purchase new equipment which serves as collateral for the certificate.
6
Unsecured Bonds
Federal, state and local government issues are unsecured.
Debentures are long-term corporate unsecured bonds. Senior, Junior, Subordinated.
Income bonds require interest to be paid only to the extent that it is earned as current income. Failure to make interest payments will not force the firm into bankruptcy.
7
The Composition of the Bond Market
Federal government is the single largest borrower. T-bills, T-notes, T-bonds and T-Strips Treasury Inflation Protection Securities (TIPS)
Federally Sponsored Credit Agency Issues Federal Home Loan Bank Export-Import Bank Federal Intermediate Credit Banks Federal Farm Credit Bank

Bond Market Investors
The bond market is dominated by large institutional investors.
They account for the more than 85% of trading.
Individual investors are active in low denomination ($1000) corporate bonds & tax-free municipal bonds and through bond mutual funds.
9
Bond Market Investors (Cont.)
Banks are strong participants in the municipal bond market.
Foreign investors bank roll 10-15% of U.S. Government debts.
The bond market is a strong primary market but a relatively weak secondary market.
Bonds generally trade O.T.C. except for a few that are listed on NYSE and AMEX.
10
Bond Ratings Sources
Two major bond-rating agencies are: Moody’s Investor Services, a subsidiary of Dunn
& Bradstreet. Standard & Poor’s, a subsidiary of McGraw Hill.
Secondary bond-rating agencies are: Fitch Investors Service Duff & Phelp, Inc.

Bond Ratings
A bond rating measures the likelihood of default. Financial ratio analysis accounts for half of the evaluation.
Analysts also consider cash flow, earnings measures and industry factors.
Bond yields and bond ratings are inversely related.

Computing Bond YieldsYield Measure Purpose
Nominal Yield Measures the coupon rate
Current yield Measures current income rate
Promised yield to maturity
Measures expected rate of return for bond held to maturity
Promised yield to call
Measures expected rate of return for bond held to first call date
Realized (horizon) yield
Measures expected rate of return for a bond likely to be sold prior to maturity. It considers specified reinvestment assumptions and an estimated sales price. It can also measure the actual rate of return on a bond during some past period of time.
14
Rates of Return
Approximate Promised Yield
APY = C + (Par – Market Price)/ NMaruity .60 ( Market Price) + .4 (Par)
Yield to Call:
AYC = C + (Call Price – Market Price)/ NCall .60 ( Market Price) + .4 (Call Price)
Approximate Realized Yield
ARY = C + (Realized Price – Market Price)/ NRealize .60 ( Market Price) + .4 (Realize Price)

Term Structure of Interest Rates
The relationship between maturity and interest rates. It is also known as the Yield Curve.
Expectations Hypothesis suggests that the long-term rate is an average of the expectations of the future short-term rates over the applicable time horizon.
Reinforced by borrower/lender strategies.

The Movement of Interest Rates (cont.)
Liquidity Preference Theory states that the shape of the yield curve is upward sloping. Investors will pay a higher price for short-term securities because they are more easily turned into cash without the risk of large price changes.
Investors demand higher returns from longer-term securities.
19
The Movement of Interest Rates (cont.)
Market Segmentation Theory focuses on the demand side of the market. Banks tend to prefer Short Term liquid securities
to match the nature of their deposits. Life insurance companies invest in Long-Term
bonds to match their Long-Term obligations.

Investment Strategy: Interest-Rate Considerations
Bond Pricing Rules
1. Bond prices and interest rates are
inversely related.
2. Prices of long-term bonds are more
sensitive to a change in yields to maturity than
short-term bonds.
3. Bond price sensitivity increases at a
decreasing rate as maturity increases.
22
Investment Strategy: Interest-Rate Considerations (cont.)
4. Bond prices are more sensitive to a decline in market YTM than to a rise in YTM.
5. Prices of low-coupon bonds are more sensitive to a change in YTM than high coupon bonds.
6. Bond prices are more sensitive when YTM is low than when YTM is high.
7. Margin trading magnifies profits and losses of bond investments by a factor of 1/(margin requirement).
23
What Determines the Price Volatility for Bonds
Five observed behaviors1. Bond prices move inversely to bond yields (interest rates)2. For a given change in yields, longer maturity bonds post larger
price changes, thus bond price volatility is directly related to maturity
3. Price volatility increases at a diminishing rate as term to maturity increases
4. Price movements resulting from equal absolute increases or decreases in yield are not symmetrical
5. Higher coupon issues show smaller percentage price fluctuation for a given change in yield, thus bond price volatility is inversely related to coupon

The maturity effect The coupon effect The yield level effect Some trading strategies
25
The Duration Measure
Since price volatility of a bond varies inversely with its coupon and directly with its term to maturity, it is necessary to determine the best combination of these two variables to achieve your objective
A composite measure considering both coupon and maturity would be beneficial
26
The Duration Measure
Developed by Frederick R. Macaulay, 1938
Where:
t = time period in which the coupon or principal payment occurs
Ct = interest or principal payment that occurs in period t
i = yield to maturity on the bond

Characteristics of Duration Duration of a bond with coupons is always less than its
term to maturity because duration gives weight to these interim payments A zero-coupon bond’s duration equals its maturity
There is an inverse relation between duration and coupon
There is a positive relation between term to maturity and duration, but duration increases at a decreasing rate with maturity
There is an inverse relation between YTM and duration Sinking funds and call provisions can have a dramatic
effect on a bond’s duration
28
Modified Duration and Bond Price Volatility
An adjusted measure of duration can be used to approximate the price volatility of a bond

m = number of payments a year

Duration and Bond Price Volatility Bond price movements will vary proportionally with
modified duration for small changes in yields An estimate of the percentage change in bond prices
equals the change in yield time modified duration

Where:
P = change in price for the bond
P = beginning price for the bond
Dmod = the modified duration of the bond
i = yield change in basis points divided by 100

Trading Strategies Using Duration
Longest-duration security provides the maximum price variation
If you expect a decline in interest rates, increase the average duration of your bond portfolio to experience maximum price volatility
If you expect an increase in interest rates, reduce the average duration to minimize your price decline
Note that the duration of your portfolio is the market-value-weighted average of the duration of the individual bonds in the portfolio
