Amalgamation in the business sector typically involves the merging of two or more companies to create a new entity, where the original companies cease to exist legally, and their assets and liabilities combine under the new entity. In accounting, amalgamation involves consolidating financial statements, often occurring between entities within the same industry, such as the merger of Maruti Motors and Suzuki into Maruti Suzuki, or Satyam Computers and Tech Mahindra into Mahindra Satyam, exemplifying corporate finance amalgamation.
