Debenture Redemption Reserve clarified: applicability by issuer type and annual minimum deposit requirement for maturing debentures. No DRR is required for debentures issued by All India Financial Institutions regulated by the Reserve Bank and for Banking Companies. NBFCs registered with the Reserve Bank must maintain DRR adequacy for public issues while privately placed debentures require no DRR. Other companies (including manufacturing and infrastructure) must maintain DRR for public issues and, for listed companies, for privately placed debentures; unlisted private placements attract DRR. Companies required to maintain DRR must, before 30 April each year, deposit or invest a minimum percentage of debentures maturing in the following year in prescribed unencumbered instruments, usable only for repayment of those maturing debentures.
