An amalgamation occurs when two or more organizations cease to exist and their resources, assets and roles are consolidated into a new entity. There are two types of amalgamation - a merger, where organizations consolidate voluntarily, and a takeover, where a larger organization takes control of a smaller one. Amalgamations allow companies to achieve economies of scale, synergies, risk diversification and other benefits. They can be accounted for using either the pooling of interest method or the purchase method. The document then provides several examples of amalgamations between companies in India and their objectives.
