5. Risk & Term Structure of Interest Rates
rd = r* + IP + DRP + LP + MRP
rd = Required rate of return on a debt security.
r* = Real risk-free rate.
IP = Inflation premium.
DRP = Default risk premium.
LP = Liquidity premium.
MRP = Maturity risk premium.

6. Risk & Term Structure r = r* + IP + DRP + LP + MRP
r = nominal interest rate of a particular security (or required rate of return)
r* = real risk-free interest rate typically 1-4% depending on monetary policy assumes expected inflation = zero
IP = Inflation premium Ave. inflation over life of bond
DRP = Default risk premium Compensation for possible default Function of bond ratings

7. Risk & Term Structure r = r* + IP + DRP + LP + MRP
LP = Liquidity Premium Compensation for possible difficulty selling bond quickly at fair market value
MRP = Maturity Risk Premium Compensation for possible loss in value due to increase in interest rates over maturity of bond. Affects longer maturities more than shorter.

8. Premiums Added to r* (real risk-free rate) for Different Types of Debt
ST Treasury:
only IP for ST inflation
LT Treasury:
IP for LT inflation, MRP
ST corporate:
ST IP, DRP, LP
LT corporate:
IP, DRP, MRP, LP

9. Inflation & Interest Rates
Nominal Interest= %
- Inflation -1%
= Real Int. % =11%
If inflation =
& req’d real return =
Then Nominal rate =? =
12% 8%
=4% 8%
11%
=19%

10. Relationship b/w Nominal & Real Interest Rates, & Inflation
Nom = Real + Inflation
But, inflation not additive, it grows or compounds, so multiply
Nom = (Real) x (Infl)
And (1+Nom) = (1 + real) x (1 + infl)
Is better determinant; known as Fisher effect

11. Estimating Inflation Premium (IP)
Treasury Inflation-Protected Securities (TIPS) are indexed to inflation.
IP for a particular length maturity can be approximated as the difference between the yield on a non-indexed Treasury security of that maturity minus the yield on a TIPS of that maturity.

12. Bond Spreads, the DRP, and the LP
A “bond spread” is often calculated as the difference between a corporate bond’s yield and a Treasury security’s yield of the same maturity. Therefore:
Spread = DRP + LP.
Bond’s of large, strong companies often have very small LPs. Bond’s of small companies often have LPs as high as 2%.

13. Term Structure Yield Curve
Term structure of interest rates: the relationship between interest rates (or yields) and maturities.
A graph of the term structure is called the yield curve.

14. Hypothetical Treasury Yield Curve

15. What factors can explain shape of this yield curve?
Upward slope due to:
Increasing expected inflation
Increasing maturity risk premium
What about liquidity & default risk?

16. Treasury vs. Corporate Yield Curves relationships
Corp yield curves are higher than Treasuries, but not necessarily parallel.
Spread b/w the two yield curves widens as corporate bond rating decreases due to:
DRP & LP

17. Coupon Bonds Bond = Debt = Borrowing
Fixed Maturity (Maturity Date) = N
Par Value=Face Value=Maturity Value=$1000=FV
Coupon Rate=Stated Rate (locked in in bond contract)
Coupon payment= Coupon rate x face value=PMT
Market Rate of interest = Yield to Maturity = rate used to discount bond CF’s = I
**PV cash flow of bonds always opposite sign of PMT & FV!!!

19. Key Features of a Bond
Par value: Face amount; paid at maturity. Assume $1,000.
Coupon interest rate: Stated interest rate. Multiply by par value to get dollars of interest. Generally fixed.

20. Key Features of a Bond
Maturity: Years until bond must be repaid. Declines.
Issue date: Date when bond was issued.
Default risk: Risk that issuer will not make interest or principal payments.

21. Value of Financial Security
Value of any asset based on the net present value of the expected future cash flows discounted by the interest (discount) rate that reflects risk factors
Discount (interest rate) depends on:
Riskiness of CFs reflected by DRP, MRP, LP
General level of interest rates, which reflects inflation, supply & demand for $, production opportunities, time preferences for consumption

37. What’s “yield to maturity”?
YTM is rate of return earned on a bond held to maturity. Also called “promised yield.”
It assumes bond will not default.
Includes both interest pmt component & cap gains over bond’s life
Interest rate equating bond’s price today to NPV of PMTs & FV. (Think market rate of interest)

41. Bond Prices & Int. Rates
If coupon rate < mrkt i % (rd), bond sells at a discount.
If coupon rate = i %, bond sells at its par value.
If coupon rate > i%, bond sells at a premium.
If market i% rises, price falls.

50. Call Provision
Issuer can refund if rates decline. That helps the issuer but hurts the investor.
Therefore, borrowers are willing to pay more, and lenders require more, on callable bonds.
Most bonds have a deferred call and a declining call premium
Yield to call: yearly rate of return earned on a bond until it’s called

51. Callable Bonds and Yield to Call
A 10-year, 10% semiannual coupon, $1,000 par value bond is selling for $1, with an 8% yield to maturity. It can be called after 5 years at $1,050.

52. Nominal Yield to Call (YTC)
N I/YR PV PMT FV
3.765 x 2 = 7.53%
INPUTS
OUTPUT

53. If you bought bonds, would you be more likely to earn YTM or YTC?
Coupon rate = 10% vs. YTC = rd = 7.53%. Could raise money by selling new bonds which pay 7.53%.
Could thus replace bonds which pay $100/year with bonds that pay only $75.30/year.
Investors should expect a call, hence YTC = 7.53%, not YTM = 8%.

54. Investor returns on callable bonds
In general, if a bond sells at a premium, then coupon > market rate, so a call is likely.
So, investors expect to earn:
YTC on premium bonds.
YTM on par & discount bonds.

55. Yield to Maturity vs. Yield to Call vs. Current Yield vs
Yield to Maturity vs. Yield to Call vs. Current Yield vs. Annualized Return
YTM: Yearly % rate of return if Bond held to maturity.
Includes both interest pmt component & Cap Gains over life of bond.
Also is market rate if interest
YTC: Yearly % rate of return earned on bond until it is called

56. Yield to Maturity vs. Yield to Call vs. Current Yield vs
Yield to Maturity vs. Yield to Call vs. Current Yield vs. Annualized Return
Current Yield: Think “interest yield”
Current Yield= Pmt / Price
Annualized Return: Reflects only a one-year holding period

57. What’s a sinking fund?
Provision to pay off a loan over its life rather than all at maturity.
Similar to amortization on a term loan.
Reduces risk to investor, shortens average maturity.
But not good for investors if rates decline after issuance.

58. Sinking funds are generally handled in 2 ways
Call x% at par per year for sinking fund purposes.
Call if rd is below the coupon rate and bond sells at a premium.
Buy bonds on open market.
Use open market purchase if rd is above coupon rate and bond sells at a discount.

67. What is reinvestment rate risk?
The risk that CFs will have to be reinvested at future lower rates, reducing income.
Illustration: Suppose you just won $500,000 playing the lottery. You’ll invest the money and live off interest. You buy a 1-year bond with a YTM of 10%.

68. Year 1 income = $50,000. At year-end get back $500,000 to reinvest.
If rates fall to 3%, income will drop from $50,000 to $15,000. Had you bought 30-year bonds, income would have remained constant.

69. The Maturity Risk Premium
Long-term bonds: High interest rate risk, low reinvestment rate risk.
Short-term bonds: Low interest rate risk, high reinvestment rate risk.
Nothing is riskless!
Yields on longer term bonds usually are greater than on shorter term bonds, so the MRP is more affected by interest rate risk than by reinvestment rate risk.

70. Other types of Bonds Zero coupon: Convertible: Income:
Pays no coupon & disct below par
Convertible:
To bondholder’s option
Income:
Pays interest only if interest earned by issuer; won’t bankrupt co.

71. Other types of Bonds Revenue: Floating rate:
Interest paid from revenue generated by project being financed by bonds
Floating rate:
Adjusts coupon rate periodically based on market interest rates

72. Bankruptcy Two main chapters of Federal Bankruptcy Act:
Chapter 11, Reorganization
Chapter 7, Liquidation
Typically, company wants Chapter 11, creditors may prefer Chapter 7.

73. Company has 120 days to file a reorganization plan.
If company can’t meet its obligations, it files under Chapter 11. That stops creditors from foreclosing, taking assets, and shutting down the business.
Company has 120 days to file a reorganization plan.
Court appoints a “trustee” to supervise reorganization.
Management usually stays in control.

74. Company must demonstrate in its reorganization plan that it is “worth more alive than dead.”
Otherwise, judge will order liquidation under Chapter 7.

75. If the company is liquidated, here’s the payment priority:
Past due property taxes
Secured creditors from sales of secured assets.
Trustee’s costs
Expenses incurred after bankruptcy filing
Wages and unpaid benefit contributions, subject to limits
Unsecured customer deposits, subject to limits
Taxes
Unfunded pension liabilities
Unsecured creditors
Preferred stock
Common stock

76. In a liquidation, unsecured creditors generally get zero
In a liquidation, unsecured creditors generally get zero. This makes them more willing to participate in reorganization even though their claims are greatly scaled back.
Various groups of creditors vote on the reorganization plan. If both the majority of the creditors and the judge approve, company “emerges” from bankruptcy with lower debts, reduced interest charges, and a chance for success.
