The exchange had earlier asked its trading members to submit the documents by September 30. Last month, the time was extended till October 17.
"The last date for submission of networth certificate, computation of networth, auditor's report and audited annual accounts for the financial year ended on March 31, 2016 is extended to October 31, 2016," BSE said in a circular.
The exchange has asked all the members to submit complete documents by October 31, in order to avoid any penal action for late or non-submission.
A fine of Rs 100 per day would be slapped till the first month from the due date (October 31) and Rs 200 each day from the second month after due date and Rs 300 per day till the date of submission or date of discontinuation of margin trading facility, whichever is earlier.
