1. A bond's face or maturity value is generally $1,000 and represents the amount borrowed from the bond's first purchaser.
2. A bond issuer is said to be in default if it does not pay the interest or the principal in accordance with the terms of the indenture agreement or if it violates one or more of the issue's restrictive covenants.
3. A bond contract feature that requires the issuer to retire a specified portion of the bond issue each year is called a singing fund provision.
