Jumbo share certificate issuance allowed for listed and section 25 companies via custodians with counter receipts to allottees. The amendment permits companies listed with the OTC Exchange of India and companies registered under section 25 of the Companies Act, 1956 to issue a single jumbo share certificate in favour of a Custodian and to provide counter receipts to every allottee. 'Custodian' is defined as an entity performing post-trade activities such as settlement of purchases and sales, information reporting, safekeeping of securities and participation in clearing systems to effect deliveries on behalf of clients.
