In case you missed it, on April 20, 2010, the U.S. Department of Justice and the Federal Trade Commission issued proposed revised Horizontal Merger Guidelines intended to inform companies and lawyers how the federal agencies evaluate the likely competitive impact of mergers. The proposed guidelines clarify guidelines issued by the two agencies in 1992 and last revised in 1997. The period for public comments closed June 4, 2010. These guidelines could impact physician practice merger and other related integrated joint ventures. As such, they are worth your time to take a look at. This is the time when we are going to see a lot of physician mergers and hospital acquisitions of physician medical practices.
