Combination criteria allow notice for transactions between non competing, non vertical and non complementary parties under competition law. A combination may be notified where the parties, their group entities and affiliates do not produce similar or substitutable products or services and are not engaged in activities that are at different production stages or complementary. Parties include ultimate controlling persons, acquirers, acquired enterprises, merged entities and their group members. An affiliate is defined by ten per cent or more shareholding or voting rights, board representation rights as director or observer, or access to commercially sensitive information.
