A debenture is a type of bond or rather a loan certificate given by a company that is unsecured and is supported by credit rather than collateral or physical assets. Debentures rely solely on the creditworthiness of the issuer. Like other bonds, debentures are noted in an indenture.
Every loan agreement comes standard with a form of interest that must be paid. Interest rates can be negotiable but usually appear in one of two forms: Variable or Fixed. A Variable Interest Rate loan has an interest rate on the outstanding balance that rises or falls based on the current status of the market interest rate. On the other hand, a Fixed Interest Rate loan has an interest rate that remains constant for the duration of the agreed loan term.
