Process for Physical Delivery in F&O

When will I come to know the actual obligation of shares/ funds required for positions which I will receive Physical delivery?

The actual Physical Delivery obligation will happen basis the final file received from exchange after the expiry post end of market hours and in case there are shortage of shares in customer accounts at EOD basis the final settlement file then there would be auction for the shortage of shares and such auction charges will be passed on to you and need to be borne by you. In case of shortage of funds in your account on the basis of final settlement file the same will be recovered from your account for any differential/full requirement.
