Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, transactions of a sufficient size require the parties to file a notification to the Federal Trade Commission (FTC) and the antitrust division of the U.S. Department of Justice (DOJ). (Hart-Scott-Rodino Antitrust Improvements Act of 1976, 15 U.S.C. § 18a (2015).) If either the FTC or the antitrust division suspect the transaction will limit competition, it may request additional information, known as an HSR second request.
