With that, I will turn it over to Gary.
Gary S. Guthart, Ph.D. - President and CEO: Thank you for joining us on the call today. 2013 was a challenging year for Intuitive. Trends that emerged in the second quarter of 2013 continued through the balance of the year, including revenue uncertainties for United States customers due to pressure on gynecologic surgery broadly, the implementation of the Affordable Care Act and confusion surrounding the public debate regarding some da Vinci procedures.
These factors resulted in the slowing of our growth in gynecology and a subsequent decline in the sale of systems in the United States. The year also featured several strengths in our business. Among them the publication of several large studies supporting the clinical and economic value of da Vinci use. We also experienced the acceleration of procedure growth in Europe and Japan, broad-based growth in general surgery procedures in the United States and continued adoption of our new products worldwide.
