On the basis of transferability, debentures can be classified as registered and unregistered debentures. Unregistered debentures (or bearer debentures) are freely negotiable and can be transferred by a simple endorsement. On the other hand, registered debentures can be transferred only by executing a transfer deed and filing a copy of it with the company. The registered debenture holders receive interest cheques automatically from the company whereas interest is paid on bearer debentures only on presentation.
