Perpetual debenture is also called the perpetual bond or simply Prep. It is defined as the bond with no maturity date. Therefore it is advised to be treated as the equity and not as the debt. The issuers of this bond pay coupons on the perpetual bonds for ever. In this way these people have to redeem the principal. It is due to the same reason that the phenomenon of cash flows of the perpetual bond is known as perpetuity.
