The correct answer is 90 days. Most of the time, debt is classified as nonperforming when loan payments have not been made for a period of 90 days (Standard period). A nonperforming asset is a debt obligation where the borrower has not made any previously agreed-upon interest and principal repayments to the designated lender for an extended period of time. A loan can be classified as a nonperforming asset at any point during the term of the loan or at its maturity. Important PointsType of non-performing asset:The most common nonperforming assets are term loans. Overdraft and cash credit (OD/CC) accounts were left out-of-order for more than 90 days. Agricultural advances interest or principal instalment payments remain overdue for two crop/harvest seasons for short duration crops or overdue one crop season for long duration crops. Banks are recording Non-Performing Assets (NPA) in three categories: sub-standard assets, doubtful assets, and loss assets. A sub-standard asset is an asset classified as an NPA for less than 12 months. A doubtful asset is an asset that has been non-performing for more than 12 months. Loss assets are loans with losses identified by the bank, auditor, or inspector that need to be fully written off.
