A concentration arises either where two or more previously independent undertakings merge (merger), where an undertaking acquires control of another undertaking (acquisition of control), or where a joint venture is created, performing on a lasting basis all the functions of an autonomous economic entity (full-function joint venture).
(See: Article 3(1) and (2) of the merger regulation; Commission notice on the concept of concentration (OJ C 66, 2.3.1998, p. 2).)
