Thank you, Marshall. During the fourth quarter, we sold 124 da Vinci Systems: 86 in the United States, 28 in Europe and 10 into rest of world markets. As part of the 124 System sales, 24 standard da Vinci Systems were traded in for credit against sales for new da Vinci Si Systems, and nine S Systems were traded in for Si Systems. We had a net 91 system additions to the installed base during the quarter, which brings to 1,752, the cumulative number of da Vinci Systems worldwide: 1,285 in the U.S., 316 in Europe and 151 in rest of world markets. 50 of the 124 systems installed represented repeat system sales to existing customers. The 38 system sales internationally was our strongest quarter-to-date and included six da Vinci Systems into Italy, five into Germany and three into the countries of France and Korea. Clinically, we had a strong quarter, with GYN and more specifically, benign dVH contributing the greatest absolute growth. While dVH for malignant conditions showed very good sequential growth, benign dVH growth was stronger both in actual procedure growth and in percentage growth. Additionally, overall benign GYN procedures, which included sacrocolpopexy, myomectomy and endometrial resections, also exhibited strong sequential growth. Within the segment of urology, dVP, Partial Nephrectomy and Cystectomy were all up materially on a sequential basis. And finally, head and neck, colorectal and thoracic resections all displayed strong sequential growth. Our strong fourth quarter procedure growth was not limited to a specific geography. It was global in structure. On a year-over-year comparison, overall fourth quarter procedures grew by approximately 35%, which is consistent with our overall 2010 procedure growth as well as our 2010 procedure guidance. On a global basis, we finished 2010 having completed approximately 278,000 total procedures led by dVH, representing approximately 110,000 and dVP, representing approximately 98,000. Benign GYN procedures have become a significant catalyst for growth within our overall business. dVH, da Vinci Sacrocolpopexy, Myomectomy and endometrial resections represent large business opportunities, both U.S. and internationally. And the peer-reviewed data supporting da Vinci's role within these procedures is beginning to expand. A rapidly emerging benign GYN procedure, one we have not talked a great deal about is da Vinci Myomectomy. Myomectomy is a procedure to remove a uterine fibroid while preserving a patient's uterus. Currently, the gold standard operation for myomectomy includes a lower abdominal incision. Over the past few years, traditional laparoscopic myomectomies have been performed more regularly. However, due to the extensive suturing required for adequate closure, it is considered technically difficult and therefore, limited in its clinical adoption. At the American Society of Reproductive Medicine Conference, a paper entitled 'Robotic-Assisted, Laparoscopic, and Open Myomectomy: A Comparison of Surgical Outcomes' was presented. The study was authored by a group of physicians representing the Cleveland Clinic Foundation and Case Western Reserve University. The study examined blood loss, length of stay and operating time for 575 patients within these three distinct cohorts. The three groups were case matched with comparable myomas regarding size, number and location and adjusted for age and body mass index. When comparing da Vinci Myomectomy to open myomectomy, average surgical time did increase. But average blood loss was reduced significantly by 50%, and the average hospitalization was reduced from three days to one day. When comparing da Vinci Myomectomy to traditional laparoscopy, surgical time was reduced by an average of 22 minutes and blood loss was reduced by an average of 33%. In their conclusion, the authors wrote, and I quote, "robotic-assisted myomectomy is associated with decreased estimated blood loss and length of hospital stay compared to traditional laparoscopy and open myomectomy. Despite that robotic use is associated with longer OR time compared to open procedures, it is shorter than laparoscopic approach. It appears that robotic technology is able to convert more laparotomy cases." Total GYN procedures represent nearly half of our overall procedure volume, with the overwhelming majority being comprised of procedures to treat benign conditions. We are pleased by the fact that our customers and patients are experiencing an enhanced clinical value within these large mainstream procedure categories. However, we do recognize that it makes procedure volumes more susceptible to general seasonality and macroeconomic pressures. This is due in large part to a patient's ability to postpone some treatments to a future date when it becomes more economically convenient for them. On the other end of the spectrum, we have experienced strong growth trajectories within the category that I will term very complex procedures, procedures where volumes are less seasonally affected, namely, head and neck surgery, colon and rectal surgery, renal cancer, cervical and endometrial cancer and lung cancer procedures. While some of these procedure categories are potentially large with steep growth trajectories, they are also fairly young with respect to their adoption. And therefore, individually, their contribution is currently less impactful to our overall procedure number. The fastest growing segment in 2010 was head and neck surgery. The category more than tripled in size during the year and showed exceptional sequential growth in Q4. We are seeing more and more peer-reviewed literature describing da Vinci's role within this category. In a recent edition of the journal Oncology, three surgeons from the Department of Head and Neck Surgery at the University of Texas' MD Anderson Cancer Center authored a comprehensive perspective paper entitled 'A Shifting Paradigm for Patients with Head and Neck Cancer: Transoral Robotic Surgery' or TORS. The paper reviewed the functional outcomes from various studies published by leading head and neck cancer centers such as the Mayo Clinic Rochester, University of Pennsylvania, the University of Alabama Birmingham and MD Anderson. The authors highlighted the initial study out of Penn, which reported that 25 out of their first 27 patients undergoing a da Vinci procedure for tonsillar squamous cell carcinoma attained negative margins, and the two patients with positive margins were later cleared. Local control was achieved in all 27 at six months' follow up. Next, the University of Alabama Birmingham evaluated 54 patients undergoing TORS and found that only five required a temporary tracheostomy with decannulation or removal occurring at a mean of eight days. Similar functional data was reported in a series by Moore, et al. at the Mayo Clinic. His group reported an average time to decannulation of seven days. This is a significant improvement for decannulation over conventional surgery, where it is usually reported in weeks or months rather than days. These early evaluations of oncologic and functional outcomes of TORS illustrate a minimally invasive technique that permits resection of a tumor en bloc while preserving patient swallowing ability. The MD Anderson group concluded their paper by stating, and I quote, "robotic surgery in head and neck oncology is an exciting innovation that provides significant advantages. Patients have an en bloc removal of their tumors via a minimally invasive surgery without a cervical incision, while preserving function and potentially avoiding adjuvant radiation and its long-term sequelae. While long-term oncologic functional data are needed to fully validate its use, early results are promising." That concludes my remarks, and I'll now turn the time over to Calvin.
