Many regulators, different rules
Most major economies now have competition authorities, including the European Commission, the UK's Competition and Markets Authority, China's State Administration for Market Regulation, and the Korea Fair Trade Commission, alongside the Justice Department and the Federal Trade Commission in the United States. Their rules on merger filing thresholds, review periods, and theories of harm differ, and some require filing and clearance before closing even when the local business is small. The EU also reviews foreign subsidies in certain deals and public tenders, and its digital markets rules impose obligations on large platforms. A practice that is acceptable in one country, such as a particular distribution or pricing term, may draw scrutiny in another.
Coordinating investigations and leniency
Cartel investigations increasingly cross borders, and authorities often cooperate or open cases around the same time. Some agencies conduct unannounced inspections, often called dawn raids, at company offices, and employees should know in advance whom to call and what not to do, including not deleting files or obstructing inspectors. Leniency programs reward the first company to report a cartel in many jurisdictions, but applying in one country without considering others can create problems elsewhere. Documents produced to one authority may surface in private damages claims in another. Privilege rules also differ; in the EU, for example, communications with in-house lawyers generally are not protected in Commission investigations.
Building a coordinated plan
When a matter reaches several countries, we start by mapping where the company and the counterparty do business, where filings or responses are required, and which deadlines fall first. For transactions, we work with local counsel to prepare consistent filings and to anticipate how authorities may view overlaps. For investigations, we help preserve documents, manage communications with each authority, and keep positions consistent across them. For compliance, we review contracts and practices against the rules of the markets that matter most to your business. Keeping one coordinating team usually prevents conflicting statements to different regulators.
