On Oct. 14, 2011, the U.S. Department of Justice, Federal Trade Commission and European Commission commemorated the 20th anniversary of the United States-European Union bilateral antitrust agreement, and issued a revised best practices for coordinating merger reviews. The best practices, originally issued in 2002, provide an advisory framework for interagency cooperation during merger review, and are intended to minimize the risk of divergent outcomes, enhance the efficiency of merger investigations, and reduce burdens on the merging parties. The revised best practices emphasize greater coordination among the agencies at key stages of their investigations, including consideration of potential remedies to preserve competition, and provide more guidance to firms about how to work with the agencies to coordinate and facilitate the reviews of their proposed transactions.
