Bond Features
Agreement to borrow money Amount of loan
Principal, “par value” Paid back at set date in the future “maturity”
Interest payments Coupon interest rate Percentage of principal Made on regular schedule
Example
Bond structure Principal = $1000 Maturity = 10 years Coupon = 5%, semiannual
Cashflows Pays $25 in interest every 6 months
(Interest payment is fixed.) 10 years from now pays back $1000 + $25
Bond Legal Structure
Indenture Specifies rights of bond holders
Restrictions often include Requirements on accounting practices Firm should pay taxes Constrain future borrowing Limit dividend payments on stock
Current Bond Price
Discount Price < Par
Premium Price > Par
Depends on interest ratesBond yield = coupon/price
Call Provisions
Issuer (firm) can buy back the bonds (call) at a specified price (call premium)
Call provisions specify the price, and time period in which this can happen
Most corporate bonds are callableSimilar to refinancing for individuals Important risk component for investors
Sinking Funds
Schedule to pay back principal over time
Different from call Option versus requirement
Secured Debt
Backed by some kind of property Mortgages: real estate Plant and equipment Financial assets Income streams (Mass. turnpike)
Unsecured debt (junior bonds, debentures) No asset backing Ok for large reliable firms
Difference Between Debt (Bonds) and Equity (Stock)
Voting rights D: none, E: yes
Claims on firm assets D: senior to equity, E: subordinate to debt
Maturity D: fixed, E: none
TaxesTrading/liquidity
