A growing company has a steady requirement of funds to finance its growth programs over a period of time. For this the company does not depend on any one source to raise its capital from, and therefore we have companies either going for institutional credit or bank loans, or approaching the capital market. It has been noticed that institutional credit is accessed by companies usually in controlled economies where the capital markets are not well developed. As with all other forms of credit available in the capital market the debentures too entail a fair amount of transparency and accountability on the part of the issuing company.
The main difference between debentures and bonds is that debentures have no collateral and normally carry a higher level of risk. It has been observed that bond buyers generally purchase debentures on the belief that the bond issuer would not default on the repayment.
In the case of a debenture the company is liable to pay a specified amount with interest indicating the fact that it has similarities with a certificate of loan or a loan bond. In other words a debenture is an instrument of debt executed by a company acknowledging its obligation to repay the borrowed sum at an agreed rate of interest.
