Non Convertible Debentures

In corporate finance, a debenture is a medium to long-term debt instrument used by large companies to borrow money, at a fixed rate of interest. The legal term "debenture" originally referred to a document that either creates a debt or acknowledges it, but in some countries the term is now used interchangeably with bond, loan stock or note. A debenture is thus like a certificate of loan or a loan bond evidencing the fact that the company is liable to pay a specified amount with interest and although the money raised by the debentures becomes a part of the company's capital structure, it does not become share capital. Senior debentures get paid before subordinate debentures, and there are varying rates of risk and payoff for these categories.

Debentures are generally freely transferable by the debenture holder. Debenture holders have no rights to vote in the company's general meetings of shareholders, but they may have separate meetings or votes e.g. on changes to the rights attached to the debentures. The interest paid to them is a charge against profit in the company's financial statements.

Debentures gave rise to the idea of the rich "clipping their coupons," which means that a bondholder will present their "coupon" to the bank and receive a payment each quarter (or in whatever period is specified in the agreement).

There are also other features that minimize risk, such as a "sinking fund," which means that the debtor must pay some of the value of the bond after a specified period of time. This decreases risk for the creditors, as a hedge against inflation, bankruptcy, or other risk factors. A sinking fund makes the bond less risky, and therefore gives it a smaller "coupon" (or interest payment). There are also options for "convertibility," which means a creditor may turn their bonds into equity in the company if it does well. Companies also reserve the right to call their bonds, which mean they can call it sooner than the maturity date. Often there is a clause in the contract that allows this; for example, if a bond issuer wishes to rebuy a 30-year bond at the 25th year, they must pay a premium. If a bond is called, it means that less interest is paid out.

Failure to pay a bond effectively means bankruptcy. Bondholders who have not received their interest can throw an offending company into bankruptcy, or seize its assets if that is stipulated in the contract.
