This is a course on identifying and resolving antitrust problems that arise in mergers and acquisitions. Using case studies of contemporary transactions ranging from simple negotiated acquisitions to hard-fought contested takeovers, we will examine anticipating antitrust problems and identifying possible defenses and solutions at the early stage of a deal when information is typically scare, performing more detailed analyses when more information becomes available, organizing the prosecution/defense of a transaction, navigating the DOJ/FTC merger review process, anticipating and structuring consent decree settlements, litigating merger antitrust cases, and negotiating provisions in merger agreements to allocate antitrust risk between the parties. The case studies will include such recent high-profile transactions as Hertz/Avis Budget/Dollar Thrifty, Halliburton/Baker Hughes, Staples/Office Depot, American Airlines/USAir, Comcast/NBCUniversal, Anheuser-Busch InBev/Grupo Modelo, Anthem/Cigna, and Nielsen/Arbitron. The course will be sufficiently self-contained for students interested in business combinations who have not taken an antitrust course. There will be several short graded assignments throughout the course and a three-hour, open book, take-home examination at the end of the course.
