Financial MarketsFinancial markets exist in order to allocate the
supply of savings in the economy to the demanders of those savings.
Financial markets are institutions and procedures that facilitate transactions in all types of financial claims. A securities market is simply a place where you can buy and sell securities (example, New York Stock Exchange)
4
Public Offerings Versus Private Placements
Public Offering – Both individuals and institutional investors have the opportunity to purchase securities. The securities are initially sold by the managing investment bank firm. The issuing firm never actually meets the ultimate purchaser of securities
Private Placement (direct placement) – The securities are offered and sold to a limited number of investors
5
Primary Versus Secondary MarketPrimary Market (initial issue)
Market in which new issues of a security are sold to initial buyers. This is the only time the issuing firm ever gets any money for the securities.
Example: Google raised $1.76 billion through sale of shares to public in August 2004.
Secondary Market (subsequent trading)
Market in which previously issued securities are traded. The issuing corporation does not get any money for stocks traded on the secondary market.
Example: Trading among investors today of Google stocks.
6
Money versus Capital MarketMoney Market
Market for short-term debt instruments (maturity periods of one year or less). Money market is typically a telephone and computer market (rather than a physical building)
Examples: Treasury bills (issued by federal government), commercial paper, negotiable CDs, bankers’ acceptances.
Capital Market
Market for long-term securities (maturity greater than one year).
Examples: Corporate Bonds, Common stocks, Treasury Bonds, term loans and financial leases

• Pay interest, as the name suggests.
• The value of these assets depends, at least for the most part, on interest rates.
• They all begin life as a loan of some sort, so they are all debt obligations of some issuers.
• Relatively low risk and often large denominations
Interest-Bearing Assets
9
Interest-Bearing AssetsMoney market instruments are short-term debt
obligations of large corporations and governments. These securities promise to make one future payment. When they are issued, their lives are less than one year. Relatively more liquid than longer-term fixed-income securities.
Fixed-income securities are longer-term debt obligations of corporations or governments. These securities promise to make fixed payments according to a
pre-set schedule. When they are issued, their lives exceed one year. Less liquid.
10
Examples:Treasury bills: Short-term debt of U.S.
governmentCertificates of Deposits (CDs): Time deposit
with a bankCommercial Paper: Short-term, unsecured debt
of a companyFed Funds: Very short-term loans between
banks
Money Market Securities
11
Fixed-Income SecuritiesExamples: U.S. Treasury notes, corporate bonds (callable and/or convertible, car loans, student loans. Notes and bonds are generic terms for fixed-income securities.
Potential gains/losses: Fixed coupon payments and final payment at maturity, except
when the borrower defaults. Possibility of gain (loss) from fall (rise) in interest rates. (Yes,
there is an inverse relationship between price and market interest rates.)
Depending on the debt issue, illiquidity can be a problem. (Illiquidity means it is possible that you cannot sell these securities quickly.)
12
Interest rates : Market data from WSJ
13
Bond MarketsPrimarily 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
14
Bonds Quotation
15
Corporate bondsBonds are debt securities.
When a corporation issues bonds, it is in essence issuing an IOU to bondholders.
The IOU or bond contract sets out the terms, including the principal that will be owed, the interest that will be paid, and the time at which these payments will occur.

Who issues a bond?• Domestically,
• Treasury bill, note, or bond: Issued by federal government, Called “risk-free” securities, about $4 trillion market
• Municipal bond: Issued by a local government (e.g., state or city), Often called “munis”
• Corporate bond: our focus, about $5 trillion market
• Internationally,• Euro bond: Dollar-denominated bonds sold in Germany
by GM• Foreign bond: “Yankee” bond (dollar-denominated bond
sold in U.S. by non-U.S. issuer), “Samurai” bond (Yen bonds sold in Japan by a non-Japanese borrower), etc

Bond Features Bond - evidence of debt issued by a corporation or a
governmental body. A bond represents a loan made by investors to the issuer. In return for his/her money, the investor receives a legal claim on future cash flows from the borrower. The issuer promises to: Make regular coupon (interest) payments every year or
six months until the bond matures, and Pay the face/par/maturity value of the bond when it
matures. That is, principal payment.
23

24
Elements of Bond Pricing1. Par value (par): Face amount. paid at maturity.
Usually $1,000. Entered into FV.
2. Coupon interest rate (PMT): Stated interest rate on the bond certificate. Multiply by par value to get dollars of interest to be paid. Generally fixed. Entered into to PMT.
3. Maturity (N): Years until bond must be repaid. Declines over time. Entered into N.
4. Yield-to-Maturity (YTM): The required return by investors that is used to discount the future coupon payments and face amount. Entered into I.
25
AMD promises to pay investors $60 (=6% coupon rate of $1,000) per year at year-end for next 7 years and one-time only $1,000 upon maturity.

31
If coupon rate > YTM, bond sells at a premium. (Price > Par) The premium price is to compensate the borrower for
above-market coupon rate.
If coupon rate = YTM, bond sells at its par value. (Price = Par)
If coupon rate < YTM, bond sells at a discount. (Price < Par) The discount price is to compensate the lender for
below-market coupon rate.

33
Coupon rate = A stated interest rate on the bond at the time of issuance
Yield-to-maturity = YTM is the rate of return earned on a bond held to maturity. Usually, same as the current market interest rate
for a similar investment. The discount rate that equates a bond’s price
with the present value of its future cash flows.
We are dealing with two rates!
34
YTM = Rate of return on a bond you will earn if you hold the bond until maturitySuppose you bought an AMD bond for $1,009.17. An
AMD bond pays 10% and will mature one year from now. Find the YTM.
PMT =$100 N = 1, FV = 1,000, PV = -1009.17 YTM = ?
Find the rate of return on this investment. Rate of Return = (Future Income – Initial Investment) / Initial Investment = (1,100-1009.17)/1009.17 = ?

Computing Yield-to-MaturityYield-to-maturity is the rate implied by the current

Finding the YTM requires trial and errortrial and error if you do not have a financial calculator and is similar to the process for finding r with an annuity
If you have a financial calculator, enter N, PV, PMT and FV, remembering the sign convention (PMT and FV need to have the same sign, PV the opposite sign)

Premium, Discount, and Par bond
Which of the following bonds would you buy, if you must choose one?Bond A: 12%, 1-yr, YTM = 10%, PV = 1,018.18Bond B: 10%, 1-yr, YTM = 10%, PV = 1,000Bond C: 5%, 1-yr, YTM = 10%, PV = 954.55
All of these bonds yield the same 10% return!Bond A: $1,018.18 *(1+YTM) = 1,018.18*1.1 = $1,120 Bond B: $1,000 *(1+YTM) = 1,000*1.1 = $1,100 Bond C: $954.55 *(1+YTM) = 954.55*1.1 = $1,050
46
Risks in the bond marketDefault risk
“A seller may not pay me coupons and/or principal.” The failing firm is in a financial difficulty and may not
pay coupons or principal.
Interest rate risk “A volatile interest movement may depress the value of
my bonds. (also called price risk)” Change in price due to changes in interest rates. Long-term bonds have more price risk than short-term
bonds.
47
Bond Ratings Provide One Measureof Default Risk
Low Quality, speculative, Investment-Quality Bond Ratings and/or “Junk”
High Grade Medium Grade Low Grade Very Low Grade
Standard & Poor’s AAA AA A BBB BB B CCC CC C DMoody’s Aaa Aa A Baa Ba B Caa Ca C C
Moody’s S&P
Aaa AAA Debt rated Aaa and AAA has the highest rating. Capacity to pay interest and principal is extremely strong.
Aa AA Debt rated Aa and AA has a very strong capacity to pay interest and repay principal. Together with the highest rating, this group
comprises the high-grade bond class.
A A Debt rated A has a strong capacity to pay interest and repay principal, although it is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
debt in high rated categories.
48
Bond Ratings (continued)Baa BBB Debt rated Baa and BBB is regarded as having an
adequate capacity to pay interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than in higher rated categories. These bonds are medium-grade obligations.
Ba, B BB, B Debt rated in these categories is regarded, on balance, as Caa, CCC predominantly speculative with respect to capacity to pay Ca CC interest and repay principal in accordance with the terms of the C C obligation. BB and Ba indicate the lowest degree of speculation, and Ca, CC, and C are the highest degree of speculation. Although such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions. Some issues may be in default.
D D Debt rated D is in default, and payment of interest and/or repayment of principal is in arrears.
Bond ratings are like a GPA of the firm.

Does a low coupon or high coupon bond have more risk?
Bond “Stingy Corp” is a 4% coupon bond and Bond “Generous Corp.” is a 10% coupon bond. Both bonds have 12 years to maturity, make semiannual payments, and have a YTM of 9%.
If interest rates rise by 2%, what is the percentage price change of these bonds? What if rates suddenly fall by 2% instead?
What does this problem tell you about the interest rate risk of lower-coupon bonds?
52
True or False: “All 10-year bonds have the same price risk.”
False! Low coupon bonds have more price risk than high coupon bonds.
If two bonds with different coupon rates have the same maturity, then the value of the one with the lower coupon is proportionately more dependent on the value amount to be received at maturity.
Nothing is riskless!
53
In general,
Low coupon or long maturity bonds have a greater interest
rate risk.
54
Government bond: Federal government debt Callable bond: The seller has an option to buy back
their bonds from bond investors. Convertible bond: The seller grant bondholders the
right to exchange each bond for a designated number of common stock shares of the issuing firm.
Zero-coupon bonds: “zeros” or “deep discount” bonds
Floating-rate bonds: The coupon payments are adjustable.
Inflation-indexed bonds: Protecting against inflation, Fairly new.
Other Types of Bonds
55
Government BondsTreasury Securities
Federal government debt issues T-Securities To control over money supply To fund national projects
T-bills – pure discount bonds with original maturity of one year or less
T-notes – coupon debt with original maturity between one and ten years
T-bonds - coupon debt with original maturity greater than ten years
Municipal Securities – also called “munis” Debt of state and local governments Varying degrees of default risk, rated similar to
corporate debt Interest received is tax-exempt at the federal level
56
Municipal Bond ExampleA 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
57
Callable BondIssuer can refund (“buy back”) if rates decline. That
helps the issuer but hurts the investor.
Therefore, borrowers are willing to pay more, and lenders pay less, on callable bonds.
58
Zero-Coupon BondsMake no periodic interest payments (coupon rate =
0%)
The entire yield-to-maturity comes from the difference between the purchase price and the par value
Cannot sell for more than par value
Sometimes called zeroes, or deep discount bonds
Treasury Bills are good examples of zeroes
59
Bond Characteristics, Risk and Return
Secured bond vs. a debenture – Which bond is riskier?
Subordinated (or junior) vs. senior bond – Which bond is riskier?
A callable bond vs. a non-callable bond – Which bond is riskier?

Two Kinds of Interest RatesReal rate of interest
change in purchasing power the percentage change in the amount of stuff you can
actually buy.Nominal rate of interest
quoted rate of interest, change in purchasing power and inflation
the percentage change in the amount of money you have.The nominal rate of interest includes our desired real
rate of return plus an adjustment for expected inflation
61
Two Kinds of Interest Rates (continued)
Example:
Suppose we have $1000, and Diet Coke costs $2.00 per six pack. We can buy 500 six packs. Now suppose the rate of inflation is 5%, so that the price rises to $2.10 in one year. We invest the $1000 and it grows to $1100 in one year. What’s our return in dollars? In six packs?
62
Two Kinds of Interest Rates (continued)
A. Dollars. Our return is
($1100 - $1000)/$1000 = $100/$1000 = .10.
The percentage increase in the amount of green stuff is 10%; our return is 10%.
B. Six packs. We can buy $1100/$2.10 = 523.81 six packs, so our return is
(523.81 - 500)/500 = 23.81/500 = 4.76%
The percentage increase in the amount of brown stuff is 4.76%; our return is 4.76%.
63
The Fisher EffectThe Fisher Effect defines the relationship
between real rates, nominal rates and inflation
(1 + R) = (1 + r)(1 + h), whereR = nominal rater = real rateh = expected inflation rate
ApproximationR = r + h
64
The Fisher Effect (concluded)According to the Fisher Effect:
1 + R = (1 + r) (1 + h)
Example: The nominal return is 10%, and the inflation is 5%. Calculate the real turn.
More example: If we require a 10% real return and we expect inflation to be 8%, what is the nominal rate? R = (1.1)(1.08) – 1 = .188 = 18.8% Approximation: R = 10% + 8% = 18%

Term Structure of Interest RatesTerm structure is the relationship between time to
maturity and yields, all else equal
It is important to recognize that we pull out the effect of default risk, different coupons, etc.
Yield curve – graphical representation of the term structure Normal – upward-sloping, long-term yields are higher
than short-term yields Inverted – downward-sloping, long-term yields are
lower than short-term yields

70
Factors Affecting Required Return or Yield of Corporate Bonds (rather than T-securities)
Default risk premium – remember bond ratings
Taxability premium – remember municipal versus taxable
Liquidity premium – bonds that have more frequent trading will generally have lower required returns
Anything else that affects the risk of the cash flows to the bondholders, will affect the required returns
