On May 9, 2011, the FTC is hosting a workshop to seek input on its "Proposed Statement of Antitrust Enforcement Policy," which discusses how the federal antitrust agencies will enforce U.S. antitrust laws when competing health care providers create new Accountable Care Organizations (ACOs) under the Affordable Care Act.  Note that attendees will be admitted on a first-come basis, but the event also will be webcast.
