International notifications are foreseen in several agreements between authorities, and some of them require authorities to notify its peers when analysing a merger with potential effects on other jurisdiction. However, nowadays, several mergers have effects in many international markets, so that most of them could potentially have material impact on more than one jurisdiction. This makes this type of cooperation less practical. When a waiver of confidentiality is provided, COFECE asks the parties to provide information on all the jurisdictions that are analysing the merger and only in those cases where potential effects on competition are identified, COFECE may contact its peers.
