Readings: Text Chapter 10 (up to page 354) OVERVIEW Characteristics/Types of Bonds. Basic Bond Pricing. Yield to Maturity and Associated Pricing Issues. 1 Characteristics of Bonds Bonds (or Fixed Income Securities) promise a stream of fixed cash flows payable at specific dates. Principal, Par Value, Maturity Value Maturity Coupon, Coupon Rate, Interest Rate Contingent Control Rights Covenants
2 Customizing a Bond
Covenants refer to special characteristics written into the bond contract to "customize" the bond.
Seniority/Subordination Callable & Sinking Funds Convertible Collateral (Secured) Constraints on further borrowing Constraints on dividends Constraints on asset sales How will various covenants affect price? 3 U.S. Treasury Securities
Treasury Bills (TBills): Maturity 1 year (13, 26, 52 weeks). Issued as zero coupon (discount) bonds. Issued either weekly or monthly refunding. Maturity: 2 to 10 years. Semiannual coupon payments. Treasury Notes (TNotes): Treasury Bonds (TBonds): Maturity: 10 to 30 years. Semiannual coupon payments. Treasury STRIPS (~25% of long bonds are stripped): Separate Trading of Registered Principal and Interest Securities. Inflation Indexed Bonds (TIPS)
4 Corporate Bonds
Corporate bonds can be either publicly or privately issued and traded Maturity: overnight (Commercial Paper) to 30+ years. Usually multiple issues per company. Often tailored with covenants. Risky: default risk + liquidity risk. 5 Bond Ratings
Credit rating agencies (Moody's, Standard & Poor's, Fitch) assign ratings to bonds to "quantify" default risk. Description Moody's S&P

MUNICIPAL BONDS
Issued to finance State, County, Town, School Districts Exempt from federal taxes! Issues are small and generally illiquid. OTHER BONDS

Value Additivity: Bond Price = Present Value of Promised Cash Flows. INT: coupon payment M: par value (maturity payment) N: number of periods to maturity kd: appropriate riskadjusted discount rate (e.g. required rate of return) INT INT M + INT Vd = + + ... + 2 ( 1 + k d ) (1 + k d ) (1 + k d ) n INTn M Vd = + n n (1 + k d ) n =1 (1 + k d ) N 9 Pricing a Bond: Longhand
Example: GE issues a bond: maturity = 3 years, face value = $1,000, coupon rate = 6%, rating = Aa Assume appropriate discount rate for similar bonds rated Aa is 5% and that coupons are annual. 10 Pricing a Bond: Annuity
Example: GE issues a bond: maturity = 3 years, face value = $1,000, coupon rate = 6%, rating = Aa Assume appropriate discount rate for similar bonds rated Aa is 5% and that coupons are annual. 11 Pricing a Bond: Calculator
Example: GE issues a bond: maturity = 3 years, face value = $1,000, coupon rate = 6%, rating = Aa Assume appropriate discount rate for similar bonds rated Aa is 5% and that coupons are annual. 12 Yield to Maturity
Yield to Maturity: Average Rate of Return investors will realize if the bond is held to maturity. Calculated as the single discount rate which makes price = PV of discounted cash flows. Also referred to as the bond's average rate of return or investors required rate of return. $ INT $M Vd = + t n (1 + ytm ) t =1 (1 + ytm )
13 n Calculating YTM: Calculator
Assume IBM has a 10 year, 7 % coupon bond that is priced at 985.33. Assume coupons are annual, what is its ytm? 14 Approximation for YTM

M  Vd INT + N ytm 2Vd + M 3 15 Various Domestic Yield Curves 16 Corporate Credit Spreads 17 SemiAnnual Coupons Coupon payments in U.S. are almost always semiannual. Yieldtomaturity is reported as 2*semiannual yield. Example: IBM has a 10 year, 7 % coupon bond that is priced at 985.33. Assume coupons are semiannual, what is its ytm? 18 SemiAnnual Coupons (II)
Assume Ford has a 20 year, 6.5% coupon bond. Your broker indicates that it is priced to yield 6.3%. What is its price (assume semiannual coupons). 19 Bond Price Relationships (1)
Interest Rate Price Risk: The value (price) of a bond is inversely related to changes in interest rates (and ytm). ... Price Rates ... Price Rates INT M Vd = + t (1 + k ) (1 + k ) n t =1 n Vd n  tINT  nM = + t 1 n 1 k t =1 ( 1 + k ) (1 + k )
20 Bond Price Relationships (2)
Interest Rate Price Risk and Maturity: Long term bond prices are generally more sensitive to changes in interest rates than are short term bond prices. Example: Assume that kd is 8%.
Bond A Maturity Face Value 15 years $1,000 Bond B 30 years $1,000 8% Coupon Rate 8% What is the current price of each bond? What will be the new price of each bond if kd suddenly increases to 9%?
21 Bond Price Relationships (3)
Price (Vd) will be < par value (M) if the coupon rate (c) is less than the ytm. Conversely, Vd > M if c > ytm.
A bond where Vd > M is a premium bond. A bond where Vd < M is a discount bond. A bond where Vd = M is a par bond Heuristic explanation: Coupon payments compensate investors for "giving up" their $.
"Low" coupon rate bonds: 22 Bond Price Relationships (4)
As maturity date approaches, Vd converges to M. Vd increases with maturity if c < ytm. Vd decreases with maturity if c > ytm. 23 Bond Price Relationships (4)
Example: Calculate the price of the following two bonds assuming 10 years and 9 years to maturity respectively, annual coupons, and kd = 8% Bond A Bond B $1,000 $1,000 6% 10%
24 Par Value (M) Coupon Rate (c) Bond Price Relationships (4) 10 years Bond A 9 years Bond B 25 Relationship #4 Continued
Assume you purchased bond A and held it for a year. What would be your total return?
Initial investment: Gross return after 1 year: Coupon Payment: Capital Appreciation: Percentage Return:
