Post-issue responsibilities: issuers and exchanges must ensure investor grievance redressal, demat credit, ASBA unblocking and listing. Issuers remain responsible post-issue until applicants receive demat credit or refunds and listing permission; they must coordinate with registrars and intermediaries to monitor ASBA processing, finalise allotment, credit securities to demat accounts, unblock ASBA accounts or dispatch refunds, and ensure listing. The designated stock exchange must monitor investor grievance redressal, report intermediary omissions to the Board, issue devolvement notices to underwriters within ten days where relevant, and report underwriters who fail to meet devolvement obligations in the specified format.
