We are a Mexican company planning a cross-border merger with a foreign buyer. We need to know which competition authorities must review the deal, possible notification thresholds, and typical timelines with COFECE. What due diligence documents should we assemble to facilitate the review?

This is a complex jurisdictional matter; In Mexico COFECE must be notified if the Transaction value exceeds US$ 101.5 million approx.  if not penalties ( fines) up  to 10% of the annual income of the economic agent and illegality of the transaction.


Other jurisdictions should be considered depending on the global and local turnovers/assets of the parties  where they have operations or related operations.


The Mexican process is two phases: 15 to 20 working days for the initial one, and the second form 1 to 2 months fro simple cases and 6 to 8 for more complex ones. some others up to 12 months.


Due diligence and general legal and financial documents vary from case to case, requiring close and carefully gathering and legal review before filing.


Basic but not limited to


a. All core party-related corporate  and transaction documents


b.  Tax, financial, and market-related data


C. Information  on the Party's Relationship (formal and informal), National and International Operations, and jurisdictions


D. Anti-money laundering and BFO verification of all related parties
