Slide 2
Characteristics of BondsBonds pay fixed coupon (interest) payments at fixed intervals (usually
every 6 months) and pay the par value at maturity
Par value = $1000 Coupon = 6.5% of par value per year
= $65 per year ($32.50 every 6 months) Maturity = 28 years (matures in 2029) Issued by AT&T

Types of Bonds Debentures – unsecured bonds Subordinated debentures – unsecured “junior”
debt Mortgage bonds – secured bonds Zeros – bonds that pay only par value at maturity;
no coupons Junk bonds – speculative or below-investment
grade bonds; rated BB and below. High-yield bonds
Slide 4
Types of Bonds (Continued) Eurobonds – bonds denominated in one currency
and sold in another country. (Borrowing overseas)
example – suppose Disney decides to sell $1,000 bonds in France. These are U.S. $ denominated bonds trading in a foreign country. Why do this? If borrowing rates are lower in France To avoid SEC regulations
Slide 5
Bond Indenture The bond contract between the firm and the
trustee representing the bondholders Lists all of the bond’s features: coupon, par value,
maturity, etc Lists restrictive provisions which are designed to
protect bondholders Describes repayment provisions
Slide 6
Value Book Value: value of an asset as shown on a
firm’s balance sheet; historical cost Liquidation value: amount that could be received
if an asset were sold individually Market value: observed value of an asset in the
marketplace; determined by supply and demand Intrinsic value: economic or fair value of an
asset; the present value of the asset’s expected future cash flows
Slide 7
Security Valuation In general, the intrinsic value of an asset = the present
value of the stream of expected cash flows discounted at an appropriate required rate of return
Can the intrinsic value of an asset differ from its market value?

Bond Example Suppose our firm decides to issue 20-year bonds
with a par value of $1,000 and annual coupon payments. The return on other corporate bonds of similar risk is currently 12% (required return), so we decide to offer a 12% coupon interest rate
What would be a fair price for these bonds?
Note: If the coupon rate = required return, the bond will sell for par value

Bond Markets
Primarily over-the-counter transactions with dealers connected electronically
Extremely large number of bond issues, but generally low daily volume in single issues
Makes getting up-to-date prices difficult, particularly on small company or municipal issues
Treasury securities are an exception Bond yield information is available online. One good site is
Bonds Online http://www.bondsonline.com/ Follow the “bond search,” “search/quote center,” “corporate/agency
bonds,” and “composite bond yields” links Observe the yields for various bond types, and the shape of the yield curve.

Corporate Bond Price Reporting
Coupon rate: 8.375% Coupon payment per year = $83.75 = 0.08375 X 1,000
Bond matures on July 15, 2033 Trading volume = $763,528,000 (Face value of bonds traded) Quoted price: 100.641% of face value, so if face value is 1,000, the price is
$1,006.41. Bond prices are quoted as a percent of par, just as the coupon is quoted as a
percent of par. The bond’s yield (8.316%) is 362 basis points (3.62%) above the comparable
maturity Treasury bond yield (30-year Treasury bond yield). 100 basis points = 1%
Current yield = 8.322% Computed as annual coupon divided by current price ($83.75 / $1,006.41 =
8.32%)

Corporate Bond Price Reporting – Continued
How can we determine the yield on GM bond? To do that we use another TI BA II PLUS worksheet – BOND Date entry: mm.ddyy
2ND BOND 2ND CLR WORK 01.1305 ENTER (Settlement date.) 8.375 ENTER (Annual coupon interest rate in percent form.) 07.1533 ENTER (Maturity date.) 100 ENTER (Face value entered as 100. If the bond has a call price it can be set to
that.) ACT (“ACT” is actual day count. Can be changed to “360” by using 2ND SET) 2/Y (Coupon payment per year. Can be changed to “1/Y” by using 2ND SET) Since we are computing yield (YLD) 100.641 ENTER (Non-negative price of the bond as a % of face value.) CPT (Go back to “YLD” to compute.) AI (“AI” is Accrued Interest as dollar amount per face value amount.) DUR (“DUR” is Duration of the bond – average time it takes to recover the market
price.)
Slide 22
Clean and Dirty Price of a Bond How much do you think you will pay for the previous bond per $100 par
value? Price a buyer would pay will include “Accrued Interest” (AI) if a bond is
purchased after the last coupon but before the next coupon payment This is because a seller is entitled to receive some of the next coupon
payment based on the fraction of six month period she owned it. A quotation excluding AI is called “Clean Price” What you pay for the bond is called “Dirty Price” Dirty Price = Clean Price + Accrued Interest Dirty Price = $100.641 + $4.142 = $104.783
AI is quite close to 8.375 / 2 = 4.1875 since we are short by two days to make it a full six month period (1/13/05 vs. 1/15/05)
4.1875 × 178/180 = 4.141 You pay Dirty Price (Clean Price + AI) to the seller and get the next coupon in
two days in full
Slide 23
More on Clean and Dirty Price of a Bond
Why do dealers quote clean price then? Clean prices excludes price drops of bonds due
to a coupon payment. This drop can also be observed for stock when
there is a dividend payment. Clean prices change not because of a coupon
payment but rather because of a change in general direction of interest rates or a change in the credit quality of borrower

Coupon rate = 9% Matures in November 2018 Bid price (Dealer’s Bid – dealer is willing to pay) is 145 and 25/32 percent of
par value. 145:25 = (145+25/32)% of par value = 145.78125% of par value If you want to sell $100,000 par value T-bonds, the dealer is willing to pay
1.4578125(100,000) = $145,781.25 Ask price (Dealer’s Ask – dealer is willing to receive) is 145 and 26/32 percent
of par value. 145:26 = (145+26/32)% of par value = 145.8125% of par value If you want to buy $100,000 par value T-bonds, the dealer is willing to sell them for
1.458125(100,000) = $145,812.50 The difference between the bid and ask prices is called the bid-ask spread and it
is how the dealer makes money. Note that Ask Price is higher than Bid Price. Why is that?
The price changed by 22/32 percent or $687.50 for a $100,000 worth of T-bonds (22/32)% of par.
(22/32)% = 0.6875% and 0.6875% X $100,000 = $687.50. The yield based on the ask price is 4.51%

Slide 27
Bond Pricing Theorems The following statements about bond pricing are always true.
Bond prices and market interest rates move in opposite directions
When a bond’s coupon rate is (greater than / equal to / less than) the market’s required return, the bond’s market value will be (greater than / equal to / less than) its par value
Given two bonds identical but for maturity, the price of the longer-term bond will change more than that of the shorter-term bond, for a given change in market interest rates
Given two bonds identical but for coupon, the price of the lower-coupon bond will change more than that of the higher-coupon bond, for a given change in market interest rates
Last two have implications for bond price volatility
Slide 28
Factors Affecting Bond Price Volatility The longer the maturity, The lower the coupon rate, The lower the initial required yield,
===> the larger is the effect of a change in the required yield on the price of a bond.
Slide 29
Bond Price Volatility and Duration The Duration of a bond is a linear approximation
of the percentage change in its price given a 100 basis point (one percent) change in required yield Measures a bond’s percentage price volatility For example, a bond with a duration of 7 will gain
about 7% in price if required yield falls 1%
