Uredba o združitvi ne opredeljuje koncepta skupine na abstrakten način, ampak se osredotoča na ugotavljanje, ali imajo podjetja pravico voditi poslovanje nekega podjetja, kot merilo za določanje katero podjetje, ki ima neposredne ali posredne povezave z udeleženci koncentracije, se lahko smatra, da je del njegove skupine.
The Merger Regulation does not define the concept of group in abstract terms but focuses on whether the companies have the right to manage the undertaking's affairs as the yardstick to determine which of the companies that have some direct or indirect links with an undertaking concerned should be regarded as part of its group.
