Thank you, Marshall. Our overall fourth quarter procedure growth was 17% compared to 15% during the fourth quarter of 2016 and 15% last quarter. Our Q4 procedure growth was driven by strong results globally and 16% growth in US procedures reflecting broad-based strength across our procedure categories. Q4 likely benefited modestly from cases deferred out of Q3 due to hurricanes. In total, approximately 877,000 of entry procedures are performed in 2017, up about 16% for the year. In the US general surgery on a run rate basis has surpassed gynecology as our largest specialty. Approximately 246,000 US general surgery procedures were performed in 2017, up 32% compared to 2016. 2017 growth was again driven by hernia repair, ventral and inguinal combined which continued to drive the most incremental cases, and continued da Vinci adoption in colorectal procedures. Early stage adoption and bariatric procedures and growth across the general surgery category also contributed to growth. In U.S. gynecology, fourth quarter and full year 2017 procedures grew modestly year-over-year with growth led by hysterectomy. We continue to see an increasing proportion of U.S. gynecology procedures being performed by physicians that specialized in complex benign and cancer surgery who tend to be uses of da Vinci systems. U.S. urology procedures exceeded our expectations for the fourth quarter and the year driven by proctectomy volumes. As the mature procedure category, we believe that our US proctectomy volumes have been tracking to the broader prostate surgery market, which has benefitted from recent macro trends. In other U.S. procedures, adoption of lobectomy and other thoracic procedures was again strong during the fourth quarter and full year. This set of procedures is particularly well served by our da Vinci XI system and surgical staplers. Outside the United States, approximately 233,000 procedures were performed in 2017 up approximately 21% in the fourth quarter and approximately 23% for the full year. Growth was driven by the continued adoption of da Vinci prostatectomy with solid contributions from kidney procedures and earlier stage growth in general surgery and gynecology. Fourth quarter all U.S. procedure growth was slightly lower, largely reflecting leveling system utilization and moderating growth in China as we anticipate future system sales quota. The value proposition regarding any da Vinci procedure is based upon the differentiated clinical value that can be offered to clinicians compared to other treatment alternatives including economic factors. Since the introduction of the da Vinci system, over 15,000 clinical papers have been published involving da Vinci surgery including approximately 2300 in 2017 alone. As I mentioned in my procedure discussion, long procedures in the U.S. have contributed to recent procedure growth. In November 2017, a team of investigators from the University of Southern California, the University of Michigan Ann Arbor, Penn State Health, and Intuitive published a large-scale study titled Robotic-Assisted, Video-Assisted Thoracic and Open Lobectomy: Propensity Matched Analysis of Recent Premiere Data in the Annals of Thoracic Surgery. In this study, the premier healthcare database was analyzed for open video assisted thoracic or VATS and Robotic assisted lobectomies performed between January 1, 2011 and September 30, 2015. The results from this study show a continued increase in the number of robotic assisted lobectomies during the study period. The combined total of robotic assisted and VATS approaches accounted for more than half of the lobectomies in the U.S. database indicating a strong trend towards adoption of minimally invasive approaches. While the proportion of VATS remains virtually unchanged during the study period, the robotic rate grew as open declined. After propensity score matching, which controls for heterogeneity of patients in hospitals, the robotic assisted cases were compared to VATS procedures and a sample size of 2775 in each group and robotic assisted cases were compared to open with 2951 patients in each group. Compared to open surgery, robotic assisted lobectomy demonstrated statistically significant lower post-operative complication rate, shorter hospital stay, higher percentage of patients discharged to home and lower hospital mortality rate. Compared to VATS robotic assisted surgery demonstrated statistically significant lower rate of conversion to thoracotomy, lower post-operative complication rate, shorter hospital stays and a higher percentage of patients discharged to home. As we've said in the past, we continue to invest in clinical research in our key geographic markets to assess da Vinci surgery outcomes and help educate the market. We support large scale data registries, including those managed by the American Hernia Society Quality Collaborative, and the Society of Gynecological Oncology clinical outcomes registry. As large da Vinci data sets accumulate in these registries and are compared to baseline results, the value of the da Vinci surgery can be evaluated. We also support clinical research grants at sages AFTRs and the European Colo. Proctology society as well as da Vinci fellowship programs, with several surgical societies which often yield clinical studies. I will now turn for our financial outlook for 2018. Starting with procedures, as described in our announcement earlier this month, 20 17 total da Vinci procedures grew approximately 16% to roughly 877,000 procedures performed worldwide. During 2018 we anticipate full year procedure growth within a range of 11% to 15%. We expect 2018 procedure growth to continue to be driven by U.S. general surgery and procedures outside of the United States, where we're still in earlier stages of adoption. We expect similar seasonal timing of procedures in 2018 as we've experienced in previous years, with Q1being the seasonally weakest quarter as patient deductibles are reset. In Q1, we expect a modest procedure headwind compared to Q1 2017, as a result of our estimates of working days, mostly due to the timing of the Good Friday holiday. With respect to revenue, as we've mentioned previously, capital sales are ultimately driven by procedure growth, catalyzing hospitals to establish or expand robotic system capacity. Capital sales can vary substantially from period to period based upon many factors, including U.S, healthcare policy, hospital capital spending cycles, reimbursement and government quotas, product cycles, and competitive factors. Within this framework, we'd expect 2018 capital placement seasonality to generally follow historical patterns by quarter. During the fourth quarter of 2017, 40 of the 216 system shift or 19% were under operating leases. In 2018, we'd expect the proportion of systems placed under operating leases to trend modestly up from there with variation by quarter. Turning to gross profit, our full year 2017 gross pro forma gross profit margin was 71.9%. In 2018, we expect our pro forma gross profit margin to be within a range of between 70% and 71.5% net revenue. We are projecting a modestly lower gross profit margin in 2018 reflecting higher costs associated with new products, our actual gross profit margin will vary quarter to quarter depending largely on product and regional mix. Turning to operating expenses. As Gary and Marshal described in 2018 we will continue to make substantive investments in several strategic areas that are poised to benefit the company over the long run. As a result, we expect to grow 2018 pro forma operating expenses between 16% and 18% above 2017 levels. We expect our non-cash stock compensation expense to range between 225 million and 235 million in 2018 compared to 209 million in 2017. We expect the other income which is comprised mostly of interest income to total between 45 million and 55 million in 2018. With regards to income tax, incorporating projected impacts of the new US tax law we expect our 2018 pro forma income tax rate to be between 20% and 2% of pre-tax income. Note that in the future if the IRS issues additional guidance and interpretation of the new tax law, our estimated rate may be impacted. Our share count for calculated diluted EPS pro forma EPS in Q4 was 117.4 million shares. In Q1, we expect our diluted share count to range between 117.6 million and 118.4 million shares. The actually diluted share count will depend on several factors including share price. That concludes our prepared comments. We will now open the call to your questions.
