Gary S. Guthart, Ph.D. - President and CEO: Thank you for joining us today. This quarter we continue to see significant pressure on our U.S. business. Trends that started in the first half of the year in gynecology have continued. On the procedure side, underlying causes for slowing growth include weaker overall gynecologic admissions, which is pressuring surgical volume. There are also lingering yield founded concerns regarding the benefits of da Vinci surgery compared to the available surgical alternatives.
Since we have a significant share of hysterectomy, our growth rate is sensitive to these issues. This slow growth has resulted in capacity in our U.S. installed base combined with changes in hospital capital spending associated with the implementation of the Affordable Care Act, U.S. capital sales fell substantially compared to prior year.
