Definitions for "Debenture stock"
The debt or series of debts, collectively, represented by a series of debentures; a debt secured by a trust deed of property for the benefit of the holders of shares in the debt or of a series of debentures. By the terms of much debenture stock the holders are not entitled to demand payment until the winding up of the company or default in payment; in the case of railway debentures, they cannot demand payment of the principal, and the debtor company cannot redeem the stock, except by authority of an act of Parliament.
A type of stock that makes fixed payments at scheduled intervals of time. Debenture stock differs from a debenture in that it has the status of equity, not debt, in liquidation.
Stock issued under a contract to pay specified amounts at specified intervals. The name is misleading, since it's more like preferred stock than a debenture.
