Adjustment of F&O contracts of CONCOR on account of bonus.
As per the circular, effective from July 04, 2025, the CONCOR F&O contracts will be revised based on the bonus adjustment factor.
Calculation of the adjustment factor: The adjustment factor for a bonus issue of A: B is defined as (A+B)/B. For CONCOR, the adjustment factor is (1+4)/4 = 1.25, since the bonus issue ratio of 1:4.
Adjustment for Futures Contracts:
Futures base price: The adjusted futures base price is arrived at by dividing the settlement price of the future one day before the ex-date by the adjustment factor.
Futures lot size: The adjusted market lot will be arrived at by multiplying the old market lot by the adjustment factor. The revised market lot would be 1250.
For example:
Assume you are holding a position in CONCOR JUN FUT and on pre-ex-date (July 03, 2025), futures close at 750, on the ex-date, the price will be adjusted to 600 (Price on pre-ex-date: 750 / Adjustment Factor: 1.25)
While the lot size will be adjusted to 1250 (current lot size: 1000 * adjustment factor: 1.25).
Adjustment for Options Contracts:
Strike Price: The adjusted strike price is calculated by dividing the old strike price by the adjustment factor.
Lot Size: The adjusted lot size is arrived at by multiplying the old market lot by the adjustment factor. The revised lot size would be 1250.
For example:
Assume you hold a position in CONCOR 750 CE, the current lot size is 1000. On the ex-date, the 750 CE will be adjusted to 600 (strike price 750 / adjustment factor 1.25), and the lot size will be adjusted to 1250 (current lot size: 1000 * adjustment factor 1.25).
Also, if you hold equity shares of CONCOR in your demat account as of July 04, 2025, you will be entitled to receive the bonus shares, which will be credited to your demat account usually within 2 days from the record date.
