A break-up results in one enterprise before and more than one enterprise after the event. In a break up, the enterprise is divided in such a way that neither (none) of the new enterprises keeps the identity of the original enterprise. There is no continuity or survival, but the closure of the previous enterprise is not considered to be a real death. Similarly the new enterprises are not considered to be real births. A break up is similar to split-off and can be seen as the opposite of a merger.
