Share registry centralisation requires single-point transfer operations and timely dematerialisation compliance and reporting. Issuers must centralise share registry functions either in-house or via a registered Share Transfer Agent, redress investor grievances within thirty days and report to depositories. Participants must furnish certificate-of-security details within seven days; issuers must confirm listing, cancel physical certificates and record the depository as registered owner within fifteen days, with a listing exception for unlisted companies. Issuers must submit quarterly audited reconciliation reports verifying issued, listed and dematerialised capital, confirm dematerialisation within twenty-one days or disclose delays, and notify depositories and stock exchanges of any discrepancies.
