The Board of Directors of Bank of India (BANKINDIA) has declared a dividend of ₹4.65 per equity share, with the ex-dividend date being May 29, 2026.
SEBI has prescribed a framework for exchanges to adjust derivative contracts at the time of corporate actions. The exchange has published detailed guidelines on such adjustments. As per this framework, if a company declares a dividend that is equal to or more than 2% of the market value of the underlying security, it is treated as an extraordinary dividend, and the exchange carries out adjustments in the futures and options contracts of the stock.
Since the dividend declared by BANKINDIA is above 2% of the market value of the security, the exchange has issued a circular on the adjustment of F&O contracts in BANKINDIA on the ex-date, May 29, 2026.
Adjustment for future contracts:
All positions in futures contracts of BANKINDIA will be marked-to-market on the last cum-dividend date, i.e. May 28, 2026, based on the daily settlement price of the respective futures contract. Subsequently, open positions will be carried forward at the daily settlement price less ₹4.65 (dividend amount) for the respective futures contract.
From May 29, 2026 (ex-dividend date), daily mark-to-market settlement of the futures contracts will continue as per normal procedures.
For example:
Assume you bought 1 lot (5200 quantities) of BANKINDIA May futures on May 28, 2026, at ₹142, and the daily settlement price at market close is ₹145, you would have made a mark-to-market profit of ₹3 per share.
On May 29, 2026, the previous day’s position will be carried forward at ₹140.35 (i.e. 145 − 4.65). If the closing price on May 29, 2026, is ₹143, you’ll make a mark-to-market profit of ₹2.65 per share.
Adjustment for options contracts:
The full value of the dividend, i.e. ₹4.65, will be deducted from all the cum-dividend strike prices on the ex-dividend date. All positions in existing strike prices will continue to exist in the corresponding new adjusted strike prices.
For example:
The strike price of the ₹140 Call Option will be reduced to ₹135.35 on May 29, 2026, and the positions in the ₹140 Call Option will continue to exist in the ₹135.35 Call Option.
The lot size of the F&O contracts will not change.
Also, if you hold equity shares of BANKINDIA in your Demat account as of May 29, 2026 (ex-date), you will be entitled to receive the dividend, which will be credited directly to your primary bank account within 30 to 45 days from the record date.
