The document discusses various types of business combinations under Indian law. It defines a merger as the combination of two or more companies through amalgamation or absorption, usually by offering stock in the acquiring company in exchange for shares in the target company. An acquisition is the purchase of a controlling interest in another company. A takeover implies acquiring control of a company through purchasing a majority of its shares. An amalgamation combines two companies into a new entity, with neither original company surviving. It is similar to a merger but results in a single new company rather than one company acquiring the other. A demerger transfers part of a company's business or assets to shareholders through a spin-off or new entity.
