A takeover occurs when one organization acquires control over more than 50.0% of the voting shares of another business. A takeover is considered to be friendly when the acquiree works with the acquirer to complete the acquisition transaction. A takeover is considered to be hostile when the advances of the acquirer are not welcomed and the acquiree takes steps to make it more difficult for the acquirer to complete the deal.

There are many reasons why entities engage in takeovers. An acquirer may want the intellectual property of the acquiree, or its products or property. The acquisition may allow the acquirer to fill an empty niche in its product line. Takeovers may also be defensive in nature, where the acquirer is trying to keep the acquiree away from a competitor.
