2. What is a bond?
A long-term debt instrument in which a borrower agrees to make payments of principal and interest, on specific dates, to the holders of the bond.

5. Key Features of a Bond
Par value – face amount of the bond, which is paid at maturity (assume $1,000).
Coupon interest rate – stated interest rate (generally fixed) paid by the issuer. Multiply by par value to get dollar payment of interest.
Maturity date – years until the bond must be repaid.
Issue date – when the bond was issued.
Yield to maturity - rate of return earned on a bond held until maturity (also called the “promised yield”).

8. Using a financial calculator to value a bond
This bond has a $1,000 lump sum (the par value) due at maturity (t = 10), and annual $100 coupon payments beginning at t = 1 and continuing through t = 10, the price of the bond can be found by solving for the PV of these cash flows. 10 10

9. The same company also has 10-year bonds outstanding with the same risk but a 13% annual coupon rate
This bond has an annual coupon payment of $130. Since the risk is the same the bond has the same yield to maturity as the previous bond (10%). In this case the bond sells at a premium because the coupon rate exceeds the market rate (rd). 10 10

10. The same company also has 10-year bonds outstanding with the same risk but a 7% annual coupon rate
This bond has an annual coupon payment of $70. Since the risk is the same the bond has the same yield to maturity as the previous bonds (10%). In this case, the bond sells at a discount because the coupon rate is less than the market rate (rd). 10 10 70

11. Must find the rd that solves this model.
What is the rd ( ie. Yield to maturity-YTM) on a 10-year, 9% annual coupon, $1,000 par value bond, selling for $887? (selling at Discount)
Must find the rd that solves this model.
N =10, PV = -887, Pmt = 90, FV = 1,000, I/yr = ??
YTM > Coupon

12. Find YTM, if the bond price is $1,134.20
Solving for I/YR, the YTM of this bond is 7.08%. This bond sells at a premium, because YTM < coupon rate. 10 90

13. What is interest rate (or price) risk
What is interest rate (or price) risk? Does a 1-year or 10-year bond have more interest rate risk?
Assume coupon payments is 10% and par value $1,000
Interest rate risk is the concern that rising rd will cause the value of a bond to fall.
rd 1-year Change 10-year Change
5% $1,048 $1,386
10% 1, ,000
15%
The 10-year bond is more sensitive to interest rate changes, and hence has more interest rate risk.

14. 1- year Bond (10% coupon)
I/ yr= 5%, FV= 1,000, Pmt= 100, PV= 1,047 I/ yr= 15%, FV= 1,000, Pmt= 100, PV=956

15. 10- year Bond (10% coupon)
I/ yr= 5%, FV= 1,000, Pmt= 100, PV= 1,386 I/ yr= 15%, FV= 1,000, Pmt= 100, PV= 749

16. So, the 10-year bond is more sensitive to interest rate changes, and hence has more interest rate risk. The relationship between price of bond and interest rates is inverse

Thus, if market rates , may experience income reduction

19. What is reinvestment rate risk?
Reinvestment rate risk is the concern that rd will fall, and future CFs will have to be reinvested at lower rates, hence reducing income.

20. What is the value of a 10-year, 10% semiannual coupon bond, if rd = 13%?
Multiply years by 2 : N = 2 * 10 = 20.
Divide nominal rate by 2 : I/YR = 13 / 2 = 6.5.
Divide annual coupon by 2 : PMT = 100 / 2 = 50. 20

22. Callable Bond Valuation
i.e: Northern Timber issued a $1, years bond. The bond has a call provision that allowed it to be retired any time after 5 years, with additional coupon put as penalty. The coupon rate is 18%, interest rate is 8%

Solving for the YTC is identical to solving for rd, except the time to call is used for N and the call premium is FV.

33. Default risk
If an issuer defaults, investors receive less than the promised return.
The default risk is influenced by the issuer’s financial strength and the terms of the bond contract.

34. Evaluating default risk: Bond ratings
Investment Grade
Junk Bonds
Moody’s
Aaa Aa A Baa
Ba B Caa C
S & P
AAA AA A BBB
BB B CCC D
Bond ratings are designed to reflect the probability of a bond issue going into default.

35. Factors affecting default risk and bond ratings
Debt ratio, TIE ratio, Current ratio
Bond contract provisions
Secured vs. Unsecured debt
Guarantee and sinking fund provisions
Earnings stability

36. Other types (features) of bonds
Convertible bond – may be exchanged for common stock of the firm, at the holder’s option.
Putable bond – allows holder to sell the bond back to the company prior to maturity.
Income bond – pays interest only when income is earned by the firm.
Indexed bond – interest rate paid is based upon the rate of inflation.
