SEBI has prescribed a framework to the exchanges for adjustment of corporate actions in derivative contracts at the time of the corporate action. The exchange has published everything regarding the adjustments in the case of corporate actions here. The adjustments are carried out in such a way that the value of the position of the market participants, on the cum and ex-dates for the corporate action, continue to remain the same as far as possible.
Here’s how the adjustment works out:
Calculation of the adjustment factor:
The adjustment factor for the Bonus issue of A: B is defined as (A+B)/B. In the case of PFC, the adjustment factor is (1+4)/4 = 1.25 since the bonus issue ratio is 1:4.
Adjustment for Options Contracts:
Strike Price: The adjusted strike price is arrived at 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 7750.
Example:
Assume you hold a position in PFC 275 CE, the current lot size is 6200. On ex-date, the 275 CE will be adjusted to 220 (Strike Price 275 / Adjustment Factor 1.25) and the lot size will be adjusted to 7750 (Current Lot Size: 6200 * Adjustment Factor 1.25).
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 7750.
Example:
Assume you are holding a position in PFC SEP FUT and on pre-ex-date (September 20, 2023) futures close at 280, on ex-date the price will be adjusted to 224 (Price on pre-ex-date: 280 / Adjustment Factor: 1.25)
While the lot size will be adjusted to 7750 (Current lot size: 6200 * Adjustment Factor: 1.25).
Holders of F&O contracts are not eligible for corporate action benefits.
If you are holding equity shares of PFC on ex-date (September 21, 2023) you will be eligible to receive the bonus shares. The credit of shares can take up to 15 days from the record date (September 21, 2023). You can learn more about this here.
