A review of the merger enforcement actions brought by the Federal Trade Commission (FTC) and the Antitrust Division of the Department of Justice (DOJ) in 2016, including the average length of merger investigations, common theories of harm, and trends in the use of up-front buyers and out-of-market remedies. Notable trends include a number of government victories in litigated actions and a much higher average deal value of reviewed transactions. The length of merger reviews appears to have plateaued after several years of increases.
