How many payments must a borrower miss before a loan is deemed non-performing?

When a debtor has not made scheduled payments for at least 90 days, a loan is considered to be close to being in default. Once that loan is non-performing, the chance that it will be repaid in full by the borrower is substantially lower. If the debtor does initiate payments again on a nonperforming loan, it becomes a re-performing loan — even if the borrower has not caught up on all the missed payments.
