This document provides an overview of AS-9 on revenue recognition in India. It defines revenue as the gross inflow of cash or other consideration arising from the sale of goods, rendering of services, or use of enterprise resources. The two main methods discussed are the proportionate completion method, where revenue is recognized based on performance of each act, and the completed contract method, where revenue is only recognized once the final act is complete. The document also discusses recognizing revenue from interest, royalties, and dividends, as well as the effects of uncertainties on revenue recognition and required disclosures.
