From a legal point of view, a merger is a legal consolidation of two entities into one entity, whereas an acquisition occurs when one entity takes ownership of another entity's stock, equity interests or assets.
Merger integration begins before the final merger documents are signed. It begins with senior management of both companies laying the groundwork for the merger by communicating the rationale to their employees, suppliers and the media. Planning involves scheduling the business-restructuring process, identifying and implementing cost reductions and rationalizing product and service lines.
