The changes, however, can be summarised as given below. According to the amendments, the notes can be refunded, as per the following criteria, based upon the denominations:

Less than Rs 20: One should have more than 50% of the note (single undivided piece) to get the full refund.
Rs 50 or above: One should have more than 80% of the note (single undivided piece) to get the full refund. If one has more than 40% and less or up to 80% (single undivided piece), he/she will get half of the value of note.
