This document discusses the management of non-performing assets (NPAs) in banks. It defines NPAs as loans where payments are overdue by more than 90 days. NPAs are categorized as substandard, doubtful, or loss assets depending on how long they have been non-performing. The document outlines provisioning norms banks must follow for different asset categories. Factors that contribute to NPAs include poor credit discipline, inadequate risk management, and diversion of funds by promoters. High levels of NPAs negatively impact bank profitability and capital adequacy. The document proposes preventive and resolution measures to manage NPAs.
