Enterprises may integrate to the extent that the number of existing enterprises is reduced. If two enterprises integrate entirely, the enterprises involved may lose their identity because they are dissolved beyond recognition in the new organisation. If both enterprises lose their identity, the event is called a merger. There is no continuity or survival, but the closures of the previous enterprises are not considered to be real deaths. Similarly the new enterprise is not considered to be a real birth. This event can be seen as the opposite of a break-up.
