Par value: Face amount; paid at maturity. Assume $1,000. 2. Coupon interest rate: Stated interest rate. Multiply by par value to get dollars of interest. Generally fixed. (More ) 3. Maturity: Years until bond must be repaid. Declines. 4. Issue date: Date when bond was issued. 5. Default risk: Risk that issuer will not make interest or principal payments. How does adding a call provision affect a bond? 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. 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. 1. Call x% at par per year for sinking fund purposes. 2. Buy bonds on open market. Company would call if rd is below the coupon rate and bond sells at a premium. Use open market purchase if rd is above coupon rate and bond sells at a discount.
