Book Closure Date
The Book Closure Date is the official cutoff day when a listed company freezes its shareholder registry to determine eligibility for dividends, bonus shares, and AGM attendance.
Detailed Explanation
Under the Companies Act 2063 and NEPSE listing bylaws, listed companies must announce a Book Closure Date prior to their Annual General Meeting (AGM) or corporate dividend distribution. Due to NEPSE's T+2 rolling settlement cycle, investors must buy shares at least one trading day prior to the Book Closure Date to be registered on the company's official depository books. On the morning of book closure, NEPSE automatically adjusts the stock's market price downward to reflect the distribution of bonus shares or rights offerings.
Why It Matters to You
Buying a stock on or after the Book Closure Date means you purchase at the adjusted lower price, but you forfeit the declared cash dividend or bonus shares. Understanding the date prevents costly timing mistakes.
Formula & Calculation
Adjusted Opening Price = Closing Market Price / (1 + Bonus % / 100)
- Closing Price = Stock closing price on the trading day immediately prior to book closure
- Bonus % = Declared percentage of bonus shares
If NABIL closes at NPR 600 before a 20% bonus share, Adjusted Price = 600 / (1 + 0.20) = NPR 500.00.
Where It Is Commonly Used

Common Misconceptions & Beginner Traps
If I buy shares on the Book Closure Date, I will receive the dividend.
False. You must buy at least one trading day before Book Closure. Buying on the date itself means you buy at adjusted price without dividend rights.
Nepal Financial & Regulatory Context
NEPSE adjusts stock prices for all bonus shares and rights shares. Cash dividends are adjusted only if the cash payout exceeds 10% of the market price under prevailing bylaws.
Real-World Practical Scenario
Investor holds 100 shares of a company declaring 25% bonus shares. Stock closes at NPR 500 on the day before book closure (Value: NPR 50,000). On Book Closure day, NEPSE adjusts opening price: NPR 500 / 1.25 = NPR 400. Investor receives 25 additional bonus shares in Demat after AGM. New holding: 125 shares × NPR 400 = NPR 50,000
Total monetary value remains identical on adjustment morning; share count expands.
