The document summarizes accounting standards for mergers and acquisitions under previous Indian accounting standards (AS 14) and the current Ind AS 103. Under AS 14, amalgamations were classified as mergers or purchases based on certain criteria, with mergers using pooling of interests and purchases using purchase accounting. Ind AS 103 requires all business combinations to use the acquisition method, which involves identifying assets acquired and liabilities assumed at fair value and any excess recorded as goodwill or gain. It also prohibits pooling of interests except for common control transactions.
