Thanks, Stef. I want to update you on 2 important topics this afternoon: the X-Tack U.S. limited launch and the reimbursement effort underway to bring coding and coverage to our products. We completed the limited launch earlier this week, and the results were tremendous. During the limited launch, we completed 24 cases, consisting of 13 lower GI cases and 11 cases in the upper GI tract. These cases were performed by 10 doctors across 9 different accounts. The limited launch suggested a physician learning curve after only 1 device. Several of the limited launch cases have been done without our presence after that first use. It is proving to be a see one, do one, teach one kind of product. Our very first X-Tack case was to close a large dissection at the hepatic flexure of the colon of close to 6 centimeters in size and irregularly shaped. The dissection itself to remove the large flat polyp of this size was a significant and time-consuming procedure. Closing a dissection site of this size would likely have been an OverStitch case, except that the hepatic flexure, it would have been a big access challenge with OverStitch on a gastroscope. The physician used 4 X-Tack devices to close this particular defect site. Perhaps, we would have liked a little bit more of a conservative case right out of the gate as our procedure number one, but the challenging cases represent the big unmet need and the reason why we designed X-Tack to begin with. And the device worked great in this highly challenging clinical environment. Each case in the limited launch is its own story and represents a life-changing procedure for the patient. For those 24 limited launch cases completed, the closure sites range from a relatively standard 18-millimeter size all the way to 80 millimeters, which is getting to be a really large site. During the limited launch, X-Tack has been used to close a large ESD site, all the way across the colon at the ileocecal valve close to the end of the ascending colon where the small intestine turns into the large intestine, a location where OverStitch could not reach. And the X-Tack was also used to successfully close large and irregularly shaped sites where through the scope clips, even in multiple numbers, could not span and would have been ineffective. Closure have been completed using 1 X-Tack device in the more straightforward cases, all the way up to 4 X-Tack devices in the larger and complex cases, such as the one at the ileocecal valve. The average number of X-Tack devices per case in the limited launch was 2. After each case, we asked the physician to rate the functionality and ease of use of the device across a number of performance attributes on a scale of 1 being poor and 5 being excellent, and the device has shown consistently high ratings across all performance measures, with an overall average rating of 4.7. With confirmation of X-Tack's stellar clinical performance and the closeout of our limited launch protocol, we have a very high degree of confidence as we direct our attention to scaling up our manufacturing capacity for the product. The most important capacity enhancing step in front of our manufacturing team is to convert from prototype molds to production molds, and this conversion is on track. Also, the closeout of our limited launch with such high marks gives our sales team confidence as they pursue our highest-priority target accounts and get in front of customer new product evaluation committees. In summary, as we end the limited launch, we are exactly where we hope to be. And if anything, our expectations have been exceeded. We have confirmed device function across a broad diversity of cases and array of closure needs throughout the GI track. User ratings have been excellent. Feedback is that X-Tack is easy to learn and easy to use. We are moving into the next launch stage right on schedule with an acceleration of our X-Tack commercial programs. Yesterday, we went live with the X-Tack product website and began a campaign to harvest our medical education training records to introduce this new technology to physicians who have come through our medical education programs in the past. Right now, outstanding quotes in front of customers pending their new product committee approval aggregate to a high 6-figure dollar amount. Everything learned so far suggests that X-Tack has a real opportunity to significantly disrupt the GI closure market. Shifting to reimbursement. There are activities underway for all products. First, for OverStitch, this is where most of our management team's efforts are directed with specific focus on the ESG procedure and bariatric revisions. We are closing in on the time when we expect the MERIT investigators to publish their study results, which we then plan to use as the cornerstone data piece for our ESG reimbursement strategy. All indications remain that we will see the MERIT study data accepted for publication sometime before the middle point of 2021. We do not have access to this independent study's data, but we have high confidence that the study will achieve its primary outcome objectives based on more than 80 studies and articles published in peer-reviewed literature describing and analyzing the ESG procedure since 2015. This worldwide data has been remarkably consistent in reporting favorable efficacy and safety results. As MERIT data nears release, we have turned to other groundwork that is part of the ESG reimbursement plan. In the fourth quarter, we submitted applications to begin the process for both ICD-10 coding and HCPCS coding for all OverStitch applications, including the ESG procedure and for bariatric revisions. The reviews of these code applications are in process, and the earliest date for a decision on either code application is probably October. The CPT coding effort will become better known following the publication of MERIT data, but it would be our goal for ESG coding to be considered by the CPT panel hopefully before the end of the year. The MERIT data will also be of interest to the payer communities in the U.S. and several other key countries, and we intend to engage these communities in coverage and payment discussions with the primary endpoint results once they're published. The prize for expanding the market access for the ESG procedure is very meaningful. There were an estimated 350,000 bariatric procedures performed in our direct markets during 2019, while only 7,500 ESGs were performed, largely without coverage. Each 1% increase in ESG's market share that comes with coverage is an incremental $5.6 million of revenue at today's average selling prices. And of course, a 10% market share is therefore equivalent to $56 million of revenue. In addition to reimbursement, we have plans to expand the OverStitch labeling to include both the ESG procedure and bariatric revisions. The MERIT data, again, is very critical, along with other prospectively collected ESG and revision data for this label expansion effort. Label expansion adds value because it will allow us to improve our medical education content that we provide to physicians today and also improve patient awareness. Second, there appears to be some progress with respect to U.S. codings that could be beneficial to both Orbera and X-Tack. First, for Orbera. In the fourth quarter, ICD-10 codes for the endoscopic insertion and removal of devices were approved by CMS, which are applicable to Orbera. These became effective in October. And in the fourth quarter, we saw that an application for a CPT code for intragastric balloons was on the agenda for the CPT editorial panel meeting, which occurred earlier this month. Separately, we submitted for a HCPCS code for Orbera during the fourth quarter. And we continue to be in various society and regulator discussions for the consideration of Orbera as a treatment for pre-cirrhotic NASH patients with fibrosis ever since the publication of the Mayo Clinic study on this in early 2020. This data, along with previously published data outside the United States, in our opinion, shows that Orbera has a reasonable likelihood of both technical success and clinical success in providing a more effective NASH treatment than today's standard of care. If these discussions are successful, all these codings developments could be very meaningful for our U.S. Orbera product line. But the consideration of an IGB code wasn't the only CPT panel agenda item of interest to us. Also on this same agenda was consideration for a CPT code for endoscopic submucosal dissection or what is referred to as ESD. ESD is an endoluminal procedure for the en bloc resection of larger flat gastrointestinal tumors, especially colorectal tumors. The approval of this CPT code, along with the coverage and payments down the road, would expand the already attractive addressable market for X-Tack. The AMA's website indicates that the CPT panel results will be released by March 8. Lastly, our team also filed ICD-10 and HCPCS applications for X-Tack back in December upon its 510(k) clearance. For the past few years, we have made medical education the cornerstone of our OverStitch strategy. There were 2 important elements to this. First, because endoluminal suturing was so novel, it was very important to capture physician mind share through peer-reviewed publications that describe the clinical value that endoluminal suturing can deliver. And second, we needed world-class training capability to teach physicians the mechanics of using OverStitch, which can be technically challenging to get through a learning curve and get started with. Since we implemented this strategy in 2015, OverStitch revenue CAGR has been 38% up until the 2020 coronavirus disruption. In 2020, the literature side of the strategy, though, continued to deliver results, as 73 publications and medical journals mentioned OverStitch and 35 publications mentioned our intragastric balloons. 18 of these intragastric balloon publications referenced the potential as part of the treatment for NASH. The other element of our medical education strategy, which is positioned product training, did get disrupted by COVID. Physician society meetings went virtual, and travel and group gatherings were restricted. But nonetheless, at the beginning of the fourth quarter, we restarted the mobile lab in the United States and conducted hands-on training for 75 physicians in 14 different U.S. cities. We expect this effort will refill both our new account and expanding user pipelines for OverStitch in 2021 as well as support the launch of X-Tack. Before I open the call to questions, I want to say that we will not be providing 2021 guidance today. I think it's best for Apollo's next CEO to speak to that without me setting expectations for him, and I hope you will all understand that. I will say, however, that we are off to a good start in the first quarter and tracking to produce at least 10% sales growth over the first quarter of 2020, even before considering any X-Tack contribution. We have still been experiencing through the first 2 months of the first quarter some intermittent pockets of COVID weakness, which suggests that March results could surprise in either direction, but we are doing well so far in the first quarter. And demand from our international markets, particularly from distributor markets, is improving. And of course, the U.S. is continuing to progress very well. As I've said before, as long as elective procedures are allowed and health care delivery is normal, our business will do well. So after questions and answers, I'm going to have a couple of closing comments. But on that note, we'll now open the lines for questions. John, please proceed with questions.
