Fixed – income Securities
Long Term Debt: A Review
Corporate debt can be short-term (maturity less than one year) or long-term.
Different from common stock:– Creditor’s claim on corporation is specified– Promised cash flows– Most are callable
Over half of outstanding bonds are owned by life insurance companies & pension funds
Features of Fixed Income Securities Maturity :
- The length of time until the agreement expires.- Borrowers (Issuers) are committed to meet their obligations over this period
Coupon :- The rate which used for calculating the amount of interest to be paid.
Frequency :- Quarterly : coupon will be paid every 3 months.- Semi-annual : coupon will be paid every 6 months.- annually : coupon will be paid every 1 years.
Features of Fixed Income Securities
Par Value ( redemption or face value)- The amount that borrowers promises to pay
lenders at the maturity.
Remark : Bond’s price depends on movement in interest rates. If market interest rates move above (below) the coupon rate, then a bond will sell below/discount (above/premium) par value.
Bond price is the net present value of bond’s cash flow.
The indenture, a written agreement between the borrower and a trust company, usually lists– Amount of Issue, Date of Issue, Maturity– Denomination (Par value)– Annual Coupon, Dates of Coupon Payments– Security– Sinking Funds– Call Provisions– Covenants
Features that may change over time– Rating– Yield-to-Maturity– Market price

Features of Fixed Income Securities
Protective Covenants Agreements to protect bondholders
Negative covenant: They should not:– pay dividends beyond specified amount– sell more senior debt & amount of new debt is
limited– refund existing bond issue with new bonds paying
lower interest rate– buy another company’s bonds
Positive covenant: They should:– use proceeds from sale of assets for other assets– allow redemption in event of merger or spin-off– maintain good condition of assets– provide audited financial information

Bond Ratings What is rated:
– The likelihood that the firm will default.– The protection afforded by the loan contract in the
event of default.
Who pays for ratings:– Firms pay to have their bonds rated.– The ratings are constructed from the financial
statements supplied by the firm.
Ratings can change.
Raters can disagree.

Bond Rating and Symbols
Junk bonds Anything less than an S&P “BB” or a Moody’s
“Ba” is a junk bond.
A polite euphemism for junk is high-yield bond.
There are two types of junk bonds:– Original issue junk—possibly not rated– Fallen angels—rated
Current status of junk bond market– Private placement
Yield premiums versus default risk
Types of Bond Fixed rate : the coupon rate constantly fixed.
Floating rate : the coupon rate based on a reference rate (i.e. LIBOR)
Amortizing bond : some partial of principle were scheduled to pay out before the maturity.
Zero-coupon bond : pay no interest and are sold at a discount from their par value. The difference represents the interest costs to the borrower.
Types of Bond
Callable bond : issuer has right to redeem a bond before maturity at a formula price.
To compensate the call risk, investors usually need additional rate of return which may incur higher cost of borrowing to the issuer.
When market interest rate keeps lowing, issuer might execute call since he upsets with his high cost of borrowing
Types of Bond
Puttable bond : investors have right to redeem the bond before maturity at a formula price.
Put option is a sweetener which help issuer to lower his cost of borrowing.
When market interest keeps soaring, investors might execute put option since they can reinvestment at the higher rate of return.
Types of Bond Convertible bonds :
- Why are they issued? Cheap interest burden- Why are they purchased? Right for converting
- Conversion ratio:Number of shares of stock acquired by conversion
- Conversion price:Bond par value / Conversion ratio
- Conversion value:Price per share of stock x Conversion ratio
- In-the-money versus out-the-money
Reasons for Issuing Warrants and Convertibles Convertible debt carries a lower coupon rate than
does otherwise-identical straight debt.
Since convertible debt is originally issued with an out-of-the-money call option, one can argue that convertible debt allows the firm to sell equity at a higher price than is available at the time of issuance. However, the same argument can be used to say that it forces the firm to sell equity at a lower price than is available at the time of exercise.
Convertible bonds also allow young firms to delay expensive interest costs until they can afford them
Types of Bond Convertible bonds (continue) :
- Conversion ratio: 2 shares per 1 unit
- Conversion price: = (1,000 Baht / unit ) / (2 shares / unit)= 500 Baht / share
- Conversion value:= (40 Baht / share ) x ( 2 shares /
unit)= 80 Baht / unit
Types of Bond
Convertible bonds (continue) :
-The value of a convertible bond has three major components:
1. Straight bond value
2. Option value
3. Conversion value
Types of Bond Convertible bonds (continue) :
Example; Litespeed, Inc., just issued a zero coupon convertible bond due in 10 years.
- The appropriate interest rate is 10%.
- Each convertible is trading at $400 in the market.

Bond Pricing Concept checking;
Bond X and Y have the same features except
A) If X pay coupon higher than Y, how should investors value the bonds?
B) If the coupon was equally set and X has better credit rating than Y, how should investors value the bonds?
Bond X will be priced higher than Y.
Investors will require lower rate of return (represent the market rate) on X rather than Y. So, Bond X will be priced higher than Y.

Interest Rate Risk and Maturity
Malkiel’s TheoremsSummarizes the relationship among bond prices, yields, coupons, and maturity:(all theorems hold assuming everything else constant):1) Bond prices move inversely with interest rates.2) The longer the maturity of a bond, the more sensitive is it’s price to a change in interest rates.3) The price sensitivity of any bond increases with it’s maturity, but the increase occurs at a decreasing rate.4) The lower the coupon rate on a bond, the more sensitive is it’s price to a change in interest rates.5) For a given bond, the volatility of a bond is not symmetrical, i.e. a decrease in interest rates raises bond prices more than a corresponding increase in interest rates lower prices.
Duration (Macaulay’s duration) : A widely used measure of a bond's sensitivity to a 1% (1% = 100 bps) changes in interest rate (yield).
The 1st derivative of the bond’s price function with respect to yield. It’s the slope of bond price curve.
The present value-weighted number of years to maturity
Duration
Although modified duration allows us to estimates of price change in a bond’s price for a small change in required yield, it does not provide good estimates of a large price change in required yield. This is because of the convexity in the price/yield relation ship.
Convexity: a measure of the degree of curvature or convexity in the price/yield relationship.

Properties of Duration All else the same, the longer a bond’s
maturity, the longer is its duration.
All else the same, a bond’s duration increases at a decreasing rate as maturity lengthens.
All else the same, the higher a bond’s coupon, the shorter is its duration.
All else the same, a higher yield to maturity implies a shorter duration, and a lower yield to maturity implies a longer duration.

FRN Pricing
Under the assumption of no default risk, the bond should always be 100% on reset dates.
Once the coupon is fixed on a reset date, the bond tends to behave like a ST fixed-coupon bond until the next reset date.
FRN prices are more volatile just after the reset date, because that is when they have the longest fixed-coupon maturity.
Dedicated Portfolios
Dedicated portfolioA bond portfolio created to prepare for a future cash outlay, e.g. pension funds.The date the payment is due is commonly called the portfolio’s target date.
Immunization Interest rate risk: The possibility that changes in
interest rates will result in losses in a bond's value.
Reinvestment rate risk: The uncertainty about target date portfolio value that results from the need to reinvest bond coupons at yields not known in advance.
Price risk: The risk that bond prices will decrease, which arises in dedicated portfolios when the target date value of a bond or bond portfolio is not known with certainty
Immunization: Constructing a portfolio to minimize the uncertainty surrounding its target date value.
