All public issues with a value in excess of Rs 10 crore are compulsorily in the demat mode. So, if you choose to apply for such issues, you must have a demat account and mention your depository participant’s name and ID number and your client ID details in the bid/application form. In the case of fixed price issues, you are intimated through a Confirmatory Allotment Note (CAN) or a refund order, within 30 days of the closure of the issue.
In the case of book built issues, the registrar ensures that investors receive a CAN in case they have been allotted shares and the demat credit or a refund, as applicable, within 15 days of the closure of the issue. Then the stock is listed on the stock exchange within 7 days from the finalization of the issue.
