Notification of concentrations in Costa Rica Four years ago, Costa Rica introduced the obligation to report mergers and acquisitions to local antitrust authorities. In the early stages of this merger control implementation, there were some concepts that were not totally clear. However, the Commission for Promoting Competition (COPROCOM) has clarified different issues, by means of its jurisprudence. The following article analyses the current status of merger notification in Costa Rica, including the most recent developments. It also covers briefly a draft bill that is expected to be discussed in the near future at the Legislative Assembly.
