In finance, bad debt, occasionally called uncollectible accounts expense, is a monetary amount owed to a creditor that is unlikely to be paid and for which the creditor is not willing to take action to collect for various reasons, often due to the debtor not having the money to pay, for example due to a company going into liquidation or insolvency. A high bad debt rate is caused when a business is not effective in managing its credit and collections process. If the credit check of a new customer is not thorough or the collections team isn't proactively reaching out to recover payments, a company faces the risk of a high bad debt. There are various technical definitions of what constitutes a bad debt, depending on accounting conventions, regulatory treatment and the institution provisioning. In the United States, bank loans with more than ninety days' arrears become "problem loans". Accounting sources advise that the full amount of a bad debt be written off to the profit and loss account or a provision for bad debts as soon as it is foreseen.
