In pursuance of SEBI guidelines for adjustment of Futures & Options Contracts on announcement of corporate action, the members of the Equity Derivatives Segment are hereby informed the following:
HDFC BANK Ltd (Scrip Code - 500180) has informed BSE that the Company has fixed September 20, 2019 as the Record Date for the purpose of Sub-division of face value of Rs. 2 to face value of Rs.1.
In view of the above and in compliance with the aforementioned SEBI guidelines, the Exchange shall make the necessary adjustments for all the available Futures & Options contracts on the underlying scrip HDFC BANK Ltd (Derivatives Asset Code – HDBK) on end of day on September 18, 2019 the ‘ex-date’ being September 19, 2019. The adjustments to be made on account of the above corporate action in line with SEBI guidelines are given below:
A) Adjustment Factor:
If the ratio of Stock Split is say A:B, the adjustment factor is defined as A/B. The stock split ratio of HDBK is 2:1. Therefore, the adjustment factor for stock split in this case would be 2/1= 2.
Therefore, based on the above, the final adjustment factor for the scrip HDBK would be 2.
B) Adjustments for Futures & Options Contracts:
1. Strike Price: The adjusted strike price shall be arrived at by dividing the old strike price by the adjustment factor (2). The revised strike prices on account of adjustment shall be as shown below (example):

2. Market Lot: The adjusted market lot shall be arrived at by multiplying the old market lot by the adjustment factor (2).
The revised market lot would therefore be as under:
Existing Market lot - 250; Adjustment factor – 2
Revised market lot after multiplying existing market lot by adjustment factor
