Maintaining adequate F&O margins, either in cash or pledged collateral, is crucial for the physical settlement of open stock positions at expiry. In cases where no cash balance is available but sufficient collateral has been pledged, the underlying assets will be delivered to your demat account. 

However, please remember that your funds statement will reflect a negative balance equal to the settlement value and associated charges. This negative balance will accrue interest until your account is funded or the pledged collateral or holdings are liquidated as per our policy.
