Book Closure Date

The book closure date is the period during which a company temporarily closes its register of shareholders to determine the list of investors who are entitled to receive a declared dividend, participate in a rights issue, attend an Annual General Meeting (AGM), or receive any other corporate benefit. During the book closure period, which typically lasts two to three working days, share transfers are not registered — meaning any investor who purchases shares during this window will not be entitled to the upcoming corporate benefit, as the company only recognises shareholders recorded in its books before the closure began. In India, the book closure date has been largely replaced by the record date mechanism for most corporate actions on NSE and BSE, where the T+1 settlement cycle means only investors holding shares in their Demat accounts on the record date are recognised as entitled shareholders. However, both terms — book closure and record date — are still referenced in company announcements on BSE and NSE, and understanding the distinction helps investors correctly time their purchases to qualify for dividends, bonus shares, and rights entitlements.
