An amount owed by a debtor that is unlikely to be paid; for example, due to a company going into liquidation. The full amount should be written off to the profit and loss account of the period or to a provision for bad and doubtful debts as soon as it is foreseen, on the grounds of prudence. Bad debts subsequently recovered either in part or in full should be written back to the profit and loss account of the period (or to a provision for bad and doubtful debts).
