Merger refers to the situation where one of the constituent corporations remains in being and absorbs into itself the other constituent corporation. It refers to the case where no new corporation is created, but where one of the constituent corporations ceases to exist, being absorbed by the remaining corporation.
Generally, statutes authorizing the combination of corporations prescribe the steps by which consolidation or merger may be effected. The general procedure is that the constituent corporations make a contract setting forth the terms of the merger or consolidation, which is subsequently ratified by the requisite number of stockholders of each corporation.
