Gary S. Guthart, Ph.D. - President and CEO: Thank you for joining us today. As we previously announced, our second quarter has been a challenging one. Capital sales fell 5% from the prior year, with the shortfall concentrated in the United States. We attribute the miss primarily to slower than expected da Vinci benign gynecology procedure growth in the United States. Taking globally overall procedure performance in the quarter was solid, rising 18% over prior year in the phase of several headwinds.
Summarizing procedures in the United States, strong general surgery growth continued centered within Single-site cholecystectomy and colorectal resections. In gynecology dVH for malignant conditions was solid, while dVH growth for benign indications grew more slowly than expected. Urologic procedures continue to be stable.
In Europe, procedures grew sequentially over Q1, led by urology an early growth in malignant dVH. Growth was strongest in the U.K. and Nordic countries, moderate in the core countries and weakest in the South. Procedure growth in Asia was strong off of a small base, but by growth in urology and general surgery with particular strength in Japan, Taiwan and China.
Turning to systems, we sold 143 systems, 7 fewer than Q2 of 2012 with sales of new systems in the United States totaling 90, down from 124 year ago. We believe the slowing of our growth in benign gynecologic procedures in the United States to be a significant contributor to weaker than expected system sales.
There appear to be a couple of underlying causes for slower than expected U.S. benign dVH growth…
Overall admissions for benign gynecology appear to be under pressure in the first half of 2013. Since, we are a significant share of hysterectomy our growth rate in dVH is sensitive to these admissions. Second, our MCS notification and negative press occurred in the quarter, it may have pressured growth in utilization, although estimating their impact on procedure volume is difficult. Given that the average da Vinci system is used for hundreds of procedures per year, a change in da Vinci patient admissions can free capacity on existing systems and pressure new system sales. This appears to be the case this quarter.
Looking towards the second half of the year, we see increasing pressure on U.S. system sales. Globally, our business in Asia has continued to build. In Japan, system sales were strong in the quarter, showing continued interest in da Vinci surgery. Our work with surgical societies is ongoing in their efforts to obtain national reimbursement for procedures beyond prostatectomy. Currently, it appears unlikely that additional procedures will receive national reimbursement in the April 2014, insurance revision, given recent guidance from MHLW.
As we've said in the past, we continue to expect Japan's system sales to be highly variable from quarter-to-quarter. We are investing in building our team in Japan with a view towards long-term performance. Capital sales in Europe have grown over the past few quarters in a difficult environment. As we have said on prior calls, sales force changes in Europe have made a positive difference. We are gathering European clinical and reimbursement data and expect these investments to increase in the future. Given macroeconomic stresses in Europe and government processes, we expect reimbursement efforts to be a long-term endeavor.
During the quarter, FDA conducted an onsite audit of ISI and issued a set of four observations in a Form 483, previously reported in June. Yesterday, we received a warning letter from FDA as a follow on to these audit inspection findings asking for additional steps to resolve two of the observations. These concerns are addressable and we're in the process of doing so.
Turning to operating performance for the second quarter; procedures grew approximately 18% over the second quarter of 2012. We sold 143 da Vinci surgical systems, down from 150 during the second quarter of last year. Total revenue was $579 million up 8% over last year. Instrument and accessory revenue increased to $265 million, up 18% over Q2 2012. Total recurring revenue grew to $363 million, up 18% from prior year and comprising 63% of total revenues.
Net income was $159 million, up 3% over last year and we generated an operating profit of $257 million before non-cash stock option expense, down 1% from the second quarter of last year and representing 45% of Q2 revenues. We ended the quarter with $3.270 billion in cash and investments, down $89 million from last quarter. In the quarter, we generated $189 million in gross cash flow from operations which is 119% of our reported net income. And finally we repurchased $270 million of our stock.
Before turning the time over to Marshall it's worth taking a step back and looking at a longer term view of da Vinci technology and surgery. We remain deeply positive on the value da Vinci can bring to surgery now and in the future. The benefit da Vinci brings as an alternative to open surgery has been demonstrated in hundreds of peer-reviewed clinical papers and is widely accepted by our customers.
As some da Vinci procedures mature in the United States, we are increasingly exposed to volatility inpatient admissions for our core procedures and the consequent lumpiness in capital sales. Viewing over the long-term, da Vinci surgery contributes to a trend in surgery toward consolidation of procedures into fewer surgeons with higher volume. We believe this consolidation is good for patients, surgeons, hospitals and intuitive. We are still early in the global adoption of da Vinci enabled minimally invasive surgery as applied to complex conditions.
In recent quarters, we have seen building interest in the use of da Vinci in general surgery, spanning procedures from the pelvis to the upper gastrointestinal tract. As we expand our offerings and technologies like Vessel Sealing, stapling and Firefly. We are seeing increased utilization and efficiency in general surgery procedures that are otherwise very difficult to perform. Taking a recent example EndoWrist Vessel Sealers are now installed in roughly half of our U.S. customers. These technologies also open the door to additional clinical applications such as thoracic surgery, where long-term additions to stapling can bring benefit to procedures that are often difficult to perform through small incisions.
Looking at single-incision surgery, Single-Site cholecystectomy kits have been purchased by approximately half of our U.S. customers 18 months after launch. This procedure is currently growing faster than any prior da Vinci procedure. Early adopting clinical sites have been progressing and refining procedure choreography with Single-Site hysterectomy as well.
Furthermore, we are investing in expanding Single-Site technology and expect to bring to market additional Single-Site instruments, as well as integration with other da Vinci technologies, including Firefly and Simulation. As our products suite develops further, we anticipate pursuing additional clinical indications for Single-Site.
Considering trends in healthcare policy around the globe, a long-term intention to move away from fee-for-service and towards single payment per treatment event can advantage those approaches with fewer complications and fewer readmissions. Also, the trend towards public transparency of individual surgeon and hospital outcomes has the potential to shift patient dynamics toward those programs, showing the best outcomes. Again, while we cannot predict future implementations of policy, we believe their direction may set up well for da Vinci surgeons, their patients and hospital programs.
In summary, we continue to see a long-term opportunity to fundamentally improve surgery and are focused on the following. Extending the benefits of minimally invasive surgery using da Vinci and gynecology and urology worldwide. Building da Vinci capability and supporting its use in general surgery. Disciplined execution in our stapling and Single-Site product launches and finally continuing to invest in our capabilities in international markets, particularly Europe and Japan.
I'll now pass the time over to Marshall, our Chief Financial Officer.
Marshall L. Mohr - SVP and CFO: Thank you, Gary. Our second quarter was $579 million, up 8% compared with $537 million to the second-quarter of 2012 and down 5% from last quarter. Second quarter revenues by product category were as follows; second quarter instrument and accessory revenue was $265 million, up 18% compared with $224 million for the second quarter of 2012 and up 1% compared with first quarter of 2013. The year-over-year increase in instrument and accessory revenue was driven by procedure growth of 18%.
Sales of new products, including Single-Site, Vessel Sealer and Firefly, partially offset by lower instrument and accessory stocking orders associated with lower second quarter system sales. The 18% increase in da Vinci procedures for the quarter reflected strength in general surgery procedures and slower growth in benign gynecologic procedures. As Gary indicated, the slowdown in benign gynecologic growth reflects a number of factors, including but not limited to weaker hospital admissions for benign da Vinci procedures.
Our second quarter 2013U.S. dVP procedures were approximately 5% lower than the second quarter of 2012 and 2% lower than the first quarter of 2013. The sequential increase in instrument and accessory revenue compared with last quarter was driven by higher procedure volume partially offset by lower instrument and accessory stocking order.
Instrument and accessory revenue realized for procedure including initial stocking order was approximately $2,020 per procedure, which was roughly equal to the second quarter of 2012 and lower than the approximately $2,110 last quarter. The decrease compared to the first quarter reflected lower stocking orders and the timing of orders. Second quarter 2013 systems revenue of $216 million decreased 6% compared with $229 million for the second quarter of 2012 and decreased 16% compared with $256 million last quarter.
Overall we sold 143 systems in the second quarter of 2013 compared with 150 systems in the second quarter of last year and 164 systems last quarter. We sold 90 systems into the U.S. market in the second quarter of 2013 compared with 124 systems last year and 115 systems last quarter. The lower second quarter 2013 U.S. system sales reflected among other things the impact of moderating growth in U.S. benign gynecologic procedures and increased economic pressure on hospital.
During the second quarter of 2013 we sold 53 systems into international market, including 21 into Europe and 20 into Japan, compared with 26 in the international market in the second quarter of 2012, which included 13 into Europe and 7 into Japan and 49 systems in the international market in the first quarter of 2013 which included 16 into Europe and 25 into Japan. Our second quarter average sales price per system was $1.5 million, compared with $1.53 million realized in the second quarter of 2012 and the $1.55 million realized last quarter. ASPs include all da Vinci models, all simulators and Firefly when configured with the system and exclude upgrades.
Our second quarter 2013 ASPs were lower than the first quarter due to a lower proportion of dual console configurations and slightly higher proportion of sales involving trade-ins. 43 of our second quarter 2013 system sales involved trade-ins, comprised of 39 da Vince Ss and 4 standard models. 35 of our second quarter 2012 sales involved trade-ins and 39 of our first quarter 2013 sales involved trade-ins.
Service revenue increased to $98 million, up 18%, compared with $83 million last year and up 4% compared with $94 million last quarter. The growth in service revenue was primarily driven by a larger system installed base. International revenue results were as follows; second quarter revenue outside the U.S. was $158 million, up 56% compared with revenue of $101 million in the second quarter of last year and up 3% compared to $153 million last quarter.
Our higher year-over-year international revenue growth was driven primarily by higher da Vinci system sales into the Japanese and European markets. Our higher sequential international revenue was driven by higher European systems sales, partially offset by lower system sales into Japan. Second quarter 2013 international procedure volume was approximately 23% higher than the second quarter of 2012, and 6% higher than the first quarter of this year.
Moving onto the remainder of the P&L. Gross margin in the second quarter of 2013 was 70%, compared with 72% for the second quarter of 2012 and 71% for the first quarter of 2013. Our lower margin percentage compared to the second quarter of last year, resulted primarily from the impact of the medical device excise tax, enacted beginning in 2013 and product mix. Our lower gross margin percentage compared to last quarter was driven primarily by costs associated with the MCS recall, lower system ASPs and product mix.
Second quarter 2013 operating expenses of $187 million were up 16% compared with the second quarter of 2012 and up 2% compared with the first quarter of this year, a higher year-over-year operating expense increase was driven by headcount additions. Our increase compared to last quarter was driven by headcount additions, and higher legal costs offset by lower incentive compensation. Second quarter 2013 operating income was $219 million or 38% of sales, compared with $225 million or 42% of sales last year and $251 million or 41% of sales last quarter.
Second quarter 2013 operating income included $39 million of non-cash stock compensation expense compared with $33 million last year and $38 million last quarter. Our effective tax rate for the second quarter was 28.6%, compared with 32.4% for the second quarter of 2012 and 26.1% last quarter. Our second quarter rate was a bit lower than the midpoint of our 28% to 30% guidance range, primarily reflecting a higher proportion of international pretax income. Our net income was $159 million or $3.90 per share, compared with $155 million or $3.75 per share last year and $189 million $4.56 per share last quarter.
Now, moving to cash flows, we ended the second quarter with cash and investments of $3 billion down $89 million compared with March 31, 2013. The decrease was driven by $270 million used to repurchase our common stock and $25 million of capital in IT acquisitions, partially offset by $189 million in cash flow generated from operation. During the second quarter we bought back approximately 546,000 shares at an average price of $493 per share. We ended the quarter with approximately $900 million authorized by the Board for share buyback.
With that, I would like to turn it over to Alex who will go over our sales, marketing and clinical highlights.
Aleks Cukic - VP, Strategy: Thank you Marshall. During the second quarter, we sold 143 da Vinci systems, 90 in the United States, 21 into Europe and 32 into rest of world markets. As part of the 143 system sales, 4 standard da Vinci systems and 39 da Vinci S systems were traded in for credit against sales for new da Vinci Si systems. We finished the quarter with a net 89 system additions to the installed base, bringing to 2,799 the cumulative number of da Vinci systems worldwide, 2001 in the United States, 443 in Europe and 355 in rest of world markets.
61 of the 143 systems installed during the quarter represented repeat system sales to existing customers. In total 140 of the 143 systems sold represented da Vinci Si or Si-e systems, which included 27 dual console systems. The 53 system sales internationally included 20 into Japan, 4 into Russia and 3 into the countries of France, Germany, the U.K., Australia and Taiwan. Clinically Q2 year-over-year procedure growth was approximately 18%, led by the category of general surgery paced by cholecystectomy, followed by colon and rectal resections. Other general surgery procedures showing strong growth included gastric, pancreatic and esophageal procedures. Overall urology growth was solid and included strong O-U.S. dVP growth, with continued stability in U.S. dVP.
As Gary stated, our benign GYN procedure growth moderated for the second quarter in a row, which had an adverse effect on our U.S. system sales. We believe that our U.S. procedure opportunity within benign GYN remains solid, though we do recognize that the procedures remaining on the back half of the adoption curve will be more difficult to consolidate. The slower adoption within the benign GYN segment will most likely lead to continued lumpiness in U.S. system placements.
Recently released new products continue to perform well. Through Q2, we sold Single-Site instrument and accessory kits to approximately 740 U.S. customers. Our Vessel Sealer product sales were strong, with most of the interest coming from the specialties of colorectal, advanced general and GYN surgery. The customer adoption for both da Vinci simulator and Firefly continues to expand, with 96 customers purchasing a da Vinci simulator and 76 customers purchasing Firefly systems, as part of their initial system purchase this quarter.
In addition, we've expanded our phased rollout of both the da Vinci surgical stapling system and Single-Site hysterectomy products to several new sites. These rollouts will be expanded in a measured fashion, so we do not expect them to contribute materially to 2013 revenue. During the quarter, several 100 robotic abstracts and papers, representing a variety of surgical specialties were published within various peer-reviewed journals, while quarterly clinical conferences produced several live da Vinci procedure transmissions, postgraduate robotic courses, podium presentations and clinical poster sessions. So, I'll take a few moments to summarize a couple that provides interesting perspectives within the area of general surgery.
The rate of surgical convergence from a laparoscopic procedure to an open surgery is most often related to the complexity of the procedure. We've described this relationship within our urologic and gynecologic procedure businesses and believe it applies to all surgical specialties in which we participate. This past quarter, several peer-reviewed general surgery studies described da Vinci surgery within this very context. A colorectal study published in the journal Surgical Endoscopy compared 84 consecutive minimally invasive low anterior resection, 47 incorporating da Vinci and 37 employing traditional laparoscopic technique.
The study emanating out of the Division of Colon and Rectal Surgery at (indiscernible) University Hospital completed in 2000 had a median follow-up period of 31.5 months. Within their review the authors described overall safety and efficacy as similar within the two cohorts. However, the differences in the conversion rate from MIS to open and overall hospital stay were considered significant. Within the laparoscopic cohort 16.2% of the patients had required conversions to open surgical technique as compared to 2.1% within the da Vinci cohort. Though both techniques are minimally invasive the requisite hospitalization for patients undergoing the da Vinci colon and rectal resection was reduced by two days.
The author stated and I quote, 'We compared the long and short-term results for patients who underwent robotic and laparoscopic, low anterior resection and coloanal anastomosis. Robotic coloanal anastomosis had short and long-term outcomes comparable with those of laparoscopy. In particular, we found that patients in a robotic group demonstrated significantly lower rates of conversion to open surgery and had shorter hospital stay than the patients in the laparoscopic group. A low rate of conversion to open surgery has a very important impact clinically because the conversions often are associated with high complication rate and a poor prognosis.
In the annals of surgery, a study conducted at the University of Pittsburgh entitled Robotic-Assisted Minimally Invasive Distal Pancreatectomy is superior to laparoscopic technique. Compare the result of the departments first 30 da Vinci distal pancreatectomy to a historical cohort comprised of their last 94 laparoscopic distal pancreatectomies. The patients in the study demonstrated equivalent age, sex, race, ASA scores and tumor size.
Within their comments the authors noted, to their surprise that the operating time between the two cohorts showed a substantial reduction of over 75 minutes in favor of the da Vinci technique. In addition, they reported that the rate of conversion to open surgery was 16% for the laparoscopic patients versus zero among the da Vinci patients, this despite a greater probability for malignancy within the da Vinci Group.
Also noteworthy was more pancreatic ductal adenocarcinomas were approached robotically 43% then laparoscopically at 15%. Oncologic outcomes in these cases were superior for the robotic-assisted group with higher rates of margin negative resection and improved lymph node yield for both benign and malignant lesions. In their summaries, the authors wrote and I 'robotic distal pancreatectomies were equivalent to lap distal pancreatectomies and nearly all measures of outcomes and safety, but significantly reduced the risk of conversion to open resection, despite a statistically greater probability of malignancy in robotic cohort. We concluded that robotic-assistance may broaden indications for minimally invasive pancreatectomy'.
This concludes my remarks. And I'll now pass the time over to Calvin.
Calvin Darling - Senior Director of Finance: Thank you, Aleks. I will be providing you with an update to our financial forecast for 2013 on a GAAP basis. I will also provide estimates of significant non-cash expenses. Starting with procedures, on our last call, we projected full year 2013 procedures to grow towards the lower end of a range of between 20% and 23% from the base of approximately 450,000 procedures performed in 2012. Now, based upon moderating growth rates for U.S. benign gynecologic procedures, we are adjusting our projection for full year 2013 procedure growth to a range of between 15% and 18%.
Moving to revenues, as has been discussed earlier on this call capital sales of da Vinci systems are highly sensitive to changes in procedure growth patterns. Moderating procedure growth has led to increased capacity in our install base. Given the sensitivity, it is challenging for us to forecast the number of systems we expect to sell in the second half of this year. So, we have widened our guidance range. Given the significant portion of our revenue that is derived from system sales, we now expect total 2013 revenue to range from approximately flat to 7% growth compared to full year 2012.
Turning to operating income, on our last call, we forecasted operating income to fall within a range of between 38% and 39% of net revenue. At this point, given our reduced revenue expectations, we are taking steps to scale back expenses. We do not intend to make short-term spending cuts in areas that would compromise our longer-term expansion strategies. As a result, we now anticipate full year 2013 operating income to fall within a range of between 37% and 38% of revenue.
Now, with regard to non-cash stock compensation expenses. On our last call, we forecast 2013 total stock compensation to total between $184 million and $192 million for the year. Based upon our current stock price, we are reducing our forecast to a range of between $164 million and $172 million for the year.
Timing of recognition should follow a quarterly pattern similar to 2012. We expect other income, which is comprised mostly of interest income to total between $17 million and $19 million in 2013. With regard to income tax, our Q2 tax rate was 28.6% of pretax income. Our rate for the remainder of the year will likely be close to that level.
Our share count for calculating EPS in Q2 2013 was approximately 40.8 million shares. Directionally in Q3, our share count will likely modestly decline from the Q2 level. The actual share count will depend on several factors, including the magnitude and timing of share buybacks. That concludes our prepared remarks. We will now open the call to your questions.
Operator: Ben Andrew, William Blair.
Benjamin Andrew - William Blair: Wanted to follow-up on a couple of points I guess to start and Gary, you talked about the fact that system growth would likely be lumpy over the course of the coming quarters. Can you give us some sense of what your inputs have been lately from the field and from customers relative to how lumpy and what the mix between new customers and existing customers is likely to look like going forward?
Gary S. Guthart, Ph.D. - President and CEO: I think the commentary is pretty much as we've outlined it for you. We see really an issue in the U.S. of them – existing customers looking to get capacity. We don't see existing customers walking away from the technology or the opportunity but more a question of timing for them. So, we feel it's more delay than otherwise. As we've said in the past I think that capital is really driven – capital sales are really driven by three underlying drivers. One of them Is additional capacity and existing customers. One of them is technologies or new features that they would like to get. And the third are customers that are not yet da Vinci owners who are interested in engaging. We've had good success with the new technologies that we've been bringing out, and so we see that as proceeding. I think the growth rate on benign gynecologic procedures has come in in the second quarter, grew, but grew at a slower rate than we were expecting and there is just a multiple higher effect there on capacity and so the capacity constraints and existing accounts will take some quarters to workout.
Benjamin Andrew - William Blair: Gary, can you maybe give us some commentary, perhaps Alex on this about any correlation between the volume of benign GYN cases and physician visits because we've heard some noise back and forth about flattish or even sometimes declining patient volumes overall. Does that appear to be part of it? Is maybe hysterectomy being utilized less frequently? Any other things like that around the procedure growth is, obviously, a big change in hysterectomy growth. this kind of happened during the last couple of quarters?
Gary S. Guthart, Ph.D. - President and CEO: I think in terms of total inpatient admissions as a whole and then people coming in and seeking, women coming in and seeking hysterectomy. As you know, in-patient admission data broadly lags for a while. So, we get out that by more or less the same way you do by talking to our customers by looking at survey data and trying to look at other analysis. It's clear that in the first quarter, total inpatient admissions were lower than people had expected them and in some cases in some institutions negative as the total in Q2, we are hearing mixed feedback on total, and for hysterectomy as a whole, our customers are seeing a pressure both in Q1 and in Q2. Quantifying that in Q2 is tough, just because the data lags and so qualitatively we've seen some pressure there. Then there's some things that are just hard for us to handicap in terms of intuitive specific events and their impact on benign hyst, things like the MCS notification are just harder for us to quantify what that impact was.
Benjamin Andrew - William Blair: Then Calvin, I guess very briefly on the procedure guidance the 15 to 18? Does that assume that benign hysterectomy grows sequentially in the back half versus the first half? I know you've got some big year-over-year comparisons there as well. So, maybe well a different answer versus year-on-year.
Calvin Darling - Senior Director of Finance: Yeah, I think when you look at the overall guidance and the revised range we're talking about general surgery performing well and in line with our earlier guidance and similarly on the urology side and international. So, I think the change overall really is very much attributable to the benign gynecologic procedures in the U.S. And so I think, we're still talking about growth. It's a moderating growth pattern and the trajectory to the quarters ought to follow a similar patter to what we've seen historically.
Operator: Tao Levy, Wedbush Securities.
Tao Levy - Wedbush Securities: So, let's see on the warning letter that you received, it seems rather fast forward for the FDA to come in, in June and then a few weeks later give you guys a warning letter. Can you maybe go into a little more details as to what they're looking for?
Gary S. Guthart, Ph.D. - President and CEO: The content of the letter is really a reflection of the content that was in the 483 Form that was issued in June, of there, there were four observations, there were two mentions in the warning letter will become public. Two mentions of things they'd like additional insight into. One of them had to do with the procedure by which, recalls are classified and their participation in that classification. That was kind of the first bullet, and the other bullet, they want additional information on, has to do with user input and design elements, having to do with a particular product. I think those are addressable we're working on addressing them I think we can address them quickly and we'll move on.
Tao Levy - Wedbush Securities: Did the letter mention anything about having to come back and revisit the facility or?
Gary S. Guthart, Ph.D. - President and CEO: There is a mention that they will come back and audit specifically around recall classifications.
Tao Levy - Wedbush Securities: And you also mentioned about Japan now not expecting any additional reimbursed procedures in the next cycle? What did the MHLW kind of mention to you guys about that?
Gary S. Guthart, Ph.D. - President and CEO: MHLW is working on guidance documentation for reimbursement more broadly than us for new technologies, that's outlining data requirements for what they would like to see in Japan, Japan-specific data. For prostatectomy we're able to use global data and had a good interaction with MHLW. Given current guidance again I think it's a class of products more broad than us. They are looking for additional data collection in Japan specifically. That's going to vary by procedure their data requirements appear to vary by procedure, happen to do with the maturity of clinical data and so it's not all locked down yet. We're continuing to work with surgical societies who in turn work with MHLW, but given the visibility we have on it now it looks like there will be a partial reimbursement followed by national reimbursement on a timeline that has to be decided based on their data requirements. And as we get additional insight and understand it deeper we'll share that with you.
Tao Levy - Wedbush Securities: Lastly then the sort of cadence on system sales for the rest of the year, is the pressure that we should model that primarily just U.S.-based is that the right way to think about it, or do you see anything else in sort of Europe, rest of the world, Japan as well.
Gary S. Guthart, Ph.D. - President and CEO: I'll start with the broad answer and let Marshall color it as well. In the U.S., I think the dynamics that we saw in the second quarter may persist for the back half of the year. In terms of O-U.S., we're pleased with the progress we're making in Europe, but as you know, Europe can be really lumpy, and likewise in Japan, I think that Japan has had symbolysis of pent-up demand and what that looks likes in future quarters is likely to not be stable. I don't think I would use the past couple of quarters to predict the future next quarters, Marshall?
Marshall L. Mohr - SVP and CFO: Yeah, specifically in Japan we introduced Si at the beginning of the year and I think that helped drive increased system sales and we don't see that level continuing as Gary said. Europe will be lumpy particularly Q3 is a vacation period for them, and so historically, we've seen lower sales in Europe in Q3.
Operator: David Roman, Goldman Sachs.
David Roman - Goldman Sachs: Gary, I think in, both you and Aleks' prepared remarks, you referenced the volume of the data that continue to come out regarding the da Vinci system, but as you think about some of the headlines out there that have materialized in the past 6.5 months, and the rising concerns potentially from payors as it relates to hysterectomies. To what extent, have you started to rethink the need or potential need for a large-scale randomized clinical trial to really definitively put a line in the sand, on the value proposition of da Vinci that's a multicenter, multi-hundred patient clinical trial, even if it is sponsored by the Company?
Gary S. Guthart, Ph.D. - President and CEO: That's a good question. Going forward, I think clearly, large scale studies are multi-institutional, multi-surgeons are powerful and are important. Speaking to headlines a little bit, I think the headlines often confound the differences between complex procedures and simple ones and the use of da Vinci as an alternative to open, versus the use of da Vinci as an alternative to laparoscopy. I think there's a lot of very strong data, before the use of da Vinci as an alternative to open surgery. That said, going back to your comment, we are investing in large scale studies, they're not always prospective randomized trials, sometimes they're registries, sometimes they're observational trials, sometimes they're prospective randomized. It depends a lot on institutions that are doing them and the nature of the data they already have, and the data they're collecting, but we've believers in big data sets. We think that matters, and over time, we'll see more of that come out, both in hysterectomy and in other procedures.
David Roman - Goldman Sachs: Maybe just on the systems side, I certainly can appreciate that, the slowing utilization or slowing procedure volumes will impact the rate at which you sell systems, but it seems like a pretty fast drop off in system placements relative to what is – at least, looks to be in the quarter, a pretty modest slowing in procedure volumes. So, is that, am I reading that wrong, if I say that there was already a lot of capacity out there of systems, and that a small tweak on the volumes side is going to make a big impact on procedures or is it something that procedures worsen throughout the quarter, so the forward view is a little bit more cautious. I guess, am I looking at that wrong?
Gary S. Guthart, Ph.D. - President and CEO: I'll separate it into two things. I think I'm going to take the second part first. The idea of, did we see a softening at the back-end of the quarter in terms of procedures and that's driving additional conservatism for the back half of the year. We did not see a strong fall off in procedures through the quarter, it wasn't that we got to the end and procedures were really ramping down or anything like that in terms of rates. In terms of sensitivity we came out of a strong fourth quarter of '12 both in procedures and in systems. We saw some mixed dynamics in Q1 across the industry, us included in terms of procedure volumes and patient admissions and that benign hysterectomy for da Vinci growth rate really struggled to gain traction again in Q2 and I think that has added up to the sensitivity you're seeing in systems. I do think because systems are used for hundreds of procedures a year and we're doing a fair number of procedures in the U.S. that are benign hysterectomy procedures there the sensitivity that gets to the capital number.
David Roman - Goldman Sachs: And maybe lastly on the guide, the flat to up 7% total revenue guidance for the year just roughly looking at it, it looks -- it seems as though you've taken a pretty conservative approach with respect to systems and it almost looks like you're extrapolating second quarter trend and close to flat lining them through the balance of the year. So is that guidance meant to reflect the degree of uncertainty that might exist in both the capital markets, as well as some of the timing of any correlation to slowing procedure volumes and slowing system that this is a view based on what you know today and sort of taken that forward and that gives you some room on the overall performance of the business?
Aleks Cukic - VP, Strategy: David, a wider range in the revenue guidance does reflect the slower growth in da Vince procedures and really uncertainty in the trend in dVH, our underlying assumptions we assume roughly flat system utilization for the back half of the year with the reduced growth assumptions on procedures, and the rest basically falls through. Again, as we discussed the capital sales are highly sensitive to changes procedure growth trends in our guidance does assume materially fewer system sales in the second half of 2013 than the first. And a couple other points on guidance while we're on the topic, we talk a lot about system ASPs. It's probably likely the second half of systems ASPs maybe modestly lower than the first half based on a higher proportion of the sales that may involve trade-ins with the lower volumes. Then secondly, the second half instrument and accessory revenue per procedure will probably also directionally be a bit lower than we saw in the first half just based upon fewer stocking orders associated with the lower system sales.
Operator: Amit Hazan, SunTrust.
Amit Hazan - SunTrust Robinson Humphrey: Just one question on the dVH side. One of the reasons you noted for weakness was the move of hysterectomy from the inpatient to outpatient setting, but the data kind of shows pretty clearly kind of this has been an ongoing thing for years now, maybe about 5% or so a year consistently for a long time. So, I'm wondering what has really changed now, particularly this quarter for you to that noted that kind of beyond that already existing long-term trend.
Gary S. Guthart, Ph.D. - President and CEO: I think there are couple of underlying dynamics in the dVH space and actually cowing them apart and putting numbers on them is very, very tough. One of them has been we've seen over recent quarters, a pressure by payors on the use of hysterectomy as a whole, and we're hearing that back through our surgeon channels. What it takes to authorize a hysterectomy and kind of conservative medical management before that, and we're also seeing payor policies towards driving them into ambulatory settings versus in-patient settings, add to that the deductible dynamics and other macroeconomic trends and then some intuitive specific dynamics around negative press and/or MCS notification and you've got a set of things that can be contributors sorting exactly which is which in real time is very tough for us to do. It really is going to be survey data and retrospective analysis to figure out which of those is dominant. Some of them are increasing trends, some of them seem to be episodic trends.
Amit Hazan - SunTrust Robinson Humphrey: Then back to the systems side, I want to just kind of maybe touch on the deferral versus cancellation, again, I think you guys were using the word deferral in your preannouncement press release. Can you talk a little bit about the systems that maybe you were close to closing and didn't that were deferred because of the lower trajectory of expected growth for procedures and whether you're hearing in large part that, that was a deferral and not necessarily a cancellation and a move away from the technology, and are we talking virtually pretty much all of the units that fell into that bucket, or were there some that you feel were cancellation that are really moving away from your technology?
Marshall L. Mohr - SVP and CFO: The pipeline entering the quarter as we commented three months ago was strong, but as you know capital sales tend to be back ended, so it was until the end of the quarter that things started to drop off. The reasons that we were given for systems falling off included things like inability to get financing, just additional levels of approval required within hospital systems. So it just felt like a harder environment from an economic perspective. It did feel like a number of them were pushed off. Now we see them being pushed off, do they ultimately get done is really hard to predict and we don't know if someone was hesitant to buy because of hospital dynamics or concerns about the economy, whether they will still have those concerns for quarter or two out or whether those will go away and capacities will catch up such that they buy. So, it's really hard for us to predict which ones will come back and which ones will not. But the initial commentary that we're getting from hospitals was they are pushing on.
Amit Hazan - SunTrust Robinson Humphrey: Just one final one for me on utilization. I think you mentioned you're assuming flat utilization in the back half. I'm just wondering as we kind of start to think about general surgery and especially close hysterectomy in there being a shorter procedure, whether we should be considering utilization per system starting to go up a little bit more than it has been in the historical trend?
Gary S. Guthart, Ph.D. - President and CEO: It's a great point. As cholis and other simple procedures get done they are faster, they are also tend to be more schedulable. Benign disease patient can schedule into a slot, often it's better or easier than in the case of avoiding a disease. So as that becomes material and bigger I think that utilization may well go up and I think ultimately that's a good thing for hospitals and a good thing for us, but it can create some uncertainty in terms of predicting where utilization ought to settle. Now things like just to add a point colorectal procedures that are also growing are complex longer general surgery procedures and console procedures. So, you have both of those dynamics going on once and so the mix change is the thing, you have to predict to get to utilization and that's how Calvin arrived at it is guidance on.
Calvin Darling - Senior Director of Finance: I think the trends have been over last few years' gradual growth in a low mid-single digit percentage growth in utilization per system. There are almost 2,800 systems out there, now they're all at various stages of adoption. So, my point is the large sample size and that metric historically as move very gradually in direction.
Gary S. Guthart, Ph.D. - President and CEO: And long just speaking for the long-term looking out all over quarters, higher utilization is ultimately great for hospitals that get a good return on their investment and it's great for companies. So, over time if it's heads that way than you will adjust.
Operator: David Lewis, Morgan Stanley.
Jonathan Demchick - Morgan Stanley: This is Jon Demchick for David. So, you gave some numbers on the magnitude of growth rate, dVP in the quarter. But I didn't really hear I guess anything, I guess that specific towards dVH. So, I was wondering if you could give maybe additional color on the magnitude for malignant or benign and if not, if you could also maybe discuss how you're thinking about some of those pressures if they maybe more temporary or if you think that they're more permanent or structural and maybe the total addressable market that you've previously discussed maybe needs to come down a bit?
Calvin Darling - Senior Director of Finance: I mean, I don't think we're going to get specific percentage growth rates in the hysterectomy here. But I think we're on a certain trajectory I think through 2012 and then it was a noticeable change in the growth rate in Q1 that was continued out into Q2, and when we look at our guidance, I think we're projecting out our growth rates at that lower trends.
Aleks Cukic - VP, Strategy: Yeah, and as far as the addressable market, again, what we have created is really a construct for the way we think about the procedures that we can access. We talk about in the case of dVH, it started with the complex beginning with malignant endometrial cervical cancers, et cetera, and then into the complex benign and we ultimately are going after what is open surgery. There may be some intersection between laparoscopic and so on, but really the primary target, we still stand by that. We believe that, that is our target market, but what we have really realized is that as you get to the back half of these adoption curves, accessing those procedures with the same sort of approach as you did on the front half of it is difficult. In other words, they don't consolidate the same way at the same pace. So, we feel strongly about the opportunities still being there and fruitful, but the timing of it on the back end is going to be difficult to predict, and therein lies the challenge that you saw in the first couple of quarters and the affect it has on systems.
Jonathan Demchick - Morgan Stanley: Kind of thinking more on the dVH side also, will the dVH outlook maybe impact any hiring that's going on in the procedure side for general surgery or maybe affect the balance of just reps that you have in access – in both areas?
Gary S. Guthart, Ph.D. - President and CEO: As we think about opportunity, we look at it, in terms of procedure growth regionally, so we look out at U.S. in the various regions and see what opportunity and penetration levels look like and they're non-uniform. It's not that the whole country is all at the same level of adoption, and as adoption is deep in some areas for gynecology that fees resources to pursue general surgery and other things and so that's really how we're directing our sales force.
Jonathan Demchick - Morgan Stanley: Then just one quick follow-up on the buyback authorization from March. I was just wondering if you could give any additional color on your thoughts towards the capital deployment and maybe timing?
Marshall L. Mohr - SVP and CFO: So, it will be consistent with what we've said in the past. I mean, we'll look for the right opportunity to buy back shares, so looking for discontinuities in the stock price in the market and we have it authorized and we intend to use it appropriately.
Operator: Tycho Peterson, JPMorgan.
Tycho Peterson - JPMorgan: I guess, first one just on kind of the general roadmap here for general surgery. Can you talk a little bit about how sustainable you think the demand you're seeing in choli is right now, are you seeing centers trial and then either ramp up or what's the dynamic right there and then can you also talk on bariatric and maybe some of these other opportunities in general surgery beyond choli and LAR, APR?
Gary S. Guthart, Ph.D. - President and CEO: On Single-Site cholecystectomy we've seen a good stick rate. In some ways a better stick rate than past procedures in terms of early experiences and we've seen great growth out of some centers. One of the exciting things about Single-Site cholecystectomy is that number one, it's a procedure where surgeons can see high volume and so when they move they get a lot of experience quickly. So, the early part of that experience has been good. Having said that, there are absolutely some surgeons and they are absolutely some institutions, who will not participate. There are some folks who believe in the value proposition and see the benefits it's bringing to them and to patients. We've had some centers have great growth in their admissions. But there are some who are on the sidelines and they stay on the sidelines. So, I think it's going to split the field for some time. How far it penetrates and how long? I think that remains to be seen. I think there's a segment of patients that value it. I think there's a segment of surgeons who value it and who are gaining experience rapidly, but trying to call where the end is not something we can do.
Aleks Cukic - VP, Strategy: With respect to the broader category that you outlined. I think there is really two things to think about it or two ways to think about it. One is the absolute contribution of the individual procedures. So, for example, on a distal pancreatectomy or on a liver procedure or spleen procedures, esophageal, they're going to contribute in the form of I&A, but really the hidden power there is the combination of strength from the surgeon that are performing lot of the benign operations, coupled with the strength of the surgeons who are seeing demand in things like colorectal distal pancreatectomy collectively getting together into the system purchasing suite or decision is also pretty powerful. So, we don't really per se value as one for one. I think the broader you go between malignant and cancer – I should say malignant and benign the more strength you see in terms of placing systems out of that particular vertical, which we saw in gynecology and we saw in urology as well.
Gary S. Guthart, Ph.D. - President and CEO: Tycho, we'll give you a one last follow-up here.
Tycho Peterson - JPMorgan: Just on Japan, can you talk about how the growth trajectory is going to change in the absence of the new procedures and I mean you alluded to the fact they are looking for Japan's specific data, so you probably won't get the reimbursement code, but is that a definitive decision at this point that you won't get it?
Gary S. Guthart, Ph.D. - President and CEO: It is not definitive but the conversation is ongoing and per our statements we think that broad approvals across multiple procedures are unlikely. I can describe the process, what the growth rate looks like, I think is hard to predict. Process wise, we will submit data for the surgical societies, they will in turn work with MHLW. MHLW may require them to solicit and collect data in Japan that may involve a partial reimbursement for a certain number of centers and if so, then that will start the process of data collection for a group of hospitals in Japan. How many and how many procedures concurrently, we don't have resolution on yet, but as I said before, as we get closer to it, we'll share it with you.
Tycho Peterson - JPMorgan: Okay. Thank you.
Gary S. Guthart, Ph.D. - President and CEO: Okay, that was our last question. I'd like to close with a letter we received this week from a Surgeon and a Medical Director at one of the U.S. academic centers. We talk about our finances and cash flow and so on, but it sort of takes us back to what the value of our products is, and so this came from a Surgeon and Medical Director, 'The work you're doing is touching patients' lives. It's healing them and getting them better. You cannot put a price on curing someone of their cancer and doing it with minimal change to their life. It's priceless. Let that inspire you to go ahead and continue the innovation to lead surgery into the future, patients are your partners in this endeavor. Sure, everything can be refined and everything can be improved, but you only get one chance sometimes to cure someone of their cancer. Your technology has given me a step up in that pursuit. Companies that help us change patients' lives will survive and prosper.' This concludes today's call. We thank you for your participation and support on this extraordinary journey, to improve surgery and we look forward to just talking with you again in three months.
Operator: Ladies and gentlemen, that does conclude our conference for today. Thank you for your participation and for using AT&T Executive TeleConference Service. You may now disconnect.
