Thank you, Tom. As you can see from our results, we've been focused on executing our business strategy and meeting our commitment. In the U.S., a revised Centers of Excellence strategy continues to gain traction. As a reference, in 2016, we had three accounts do two implants each in North America. These were our three highest volume accounts that year. During the first six months of 2017, we've had one account perform four implants, one account performed three implants, and one account performed two implants. This is exactly what we want to see as more accounts truly adopt Argus. As a reminder, our goal is that each Center of Excellence will be a high-quality surgical center that performs at least four implants per year, possesses the ability to do regular patient screening and surgery schedule, will provide accurate post-surgery programming, and is capable of managing the artificial vision rehabilitation process. We are now taking steps to aggressively expand our account base as we're confident that we have the understanding of resource requirements and expectations for a new center and as we have referenced with respect to expanded reimbursement and qualified patient candidates, we see account expansion as a primary execution lever to grow the business. Thus far, we have added two U.S. centers this year in Gainesville, Florida and most recently in Boston and remain on track with our 2017 goal of adding a total of five to 10 centers. The new center in Boston is significant because it's our first center in New England where already have Medicare coverage. Also the Northeast is a significant expansion opportunity for us going forward with a sizable target [Indiscernible] population. Regarding our patient database, we now have 65 patient candidates who have been telephonically screened by independent medical professionals; two-thirds of these screened candidates will typically pass the final physical screening at our sites and should go to be implanted with the Argus. We have an additional 113 patient candidates that have been preliminarily qualified by our customer service team for assignment with an independent medical professional. In total, we're confident that we now have at least 50 high probability implant candidates in our database. The growth in refinement of this data base is very exciting. As we gain more experience tracking patients from initial contact through surgery, the database will create more visibility regarding potential patient implants. As a final note, 13 of the 17 implants in the first half of this year came from our database. Now, turning to Argus II in the U.S. The Novitas coverage decision was a key milestone for us. Novitas is the largest MAC in U.S., covering 11 states and the District of Columbia with a total population of about 80 million people. Argus II can now be covered in five of the eight MACs. The total population living in the states covered by these five MACs is approximately 200 million people or 62% of the U.S. population. This decision by Novitas serves as a an important bellwether for other MACs across the U.S. We continue to engage with the remaining three MACs and help filed or will file additional reconsideration requests with all non-covered MACs before year-end. As previously disclosed in an 8-K filing, CMS issued a preliminary Medicare outpatient payment rate for 2018 of $122,000 for Argus and the associated surgical implantation procedure. In determining the proposed payment rate for 2018, CMS relied on three hospital claims submitted in calendar year 2016. In 2016, the average reimbursement rate was $95,000, resulting in a lower average hospital claims than would be expected using this year's average reimbursement rate of the $150,000. We expect more claims data from 2016 to become available between now and the final ruling in November. We will continue working with our customers to stress the importance of providing complete and accurate Argus claim submissions to CMS. We will also provide comments and recommendations to CMS regarding the proposed rate during the coming months and expect other organizations and customers accounting as well. We believe that $150,000 is an appropriate outpatient payment rate that allows hospitals to be fairly reimbursed for the implanting procedure and look forward to a final ruling from CMS later this year. In addition, the CMS postings also address calendar year 2018 payments for the recently created codes for the initial programming and the reprogramming services for the Argus. The proposed hospital outpatient payment rates for the initial programming and for the reprogramming are $253 and $111 respectively. With codes established and payment rates to be finalized this year, we will start working with our customers to procure coverage for these services. Outside the U.S., we're making good progress in Asia. Through distribution partners in South Korea and Taiwan, we completed three implants in Q2. All patients are starting the rehabilitation process post-surgery and additional patients are expected to be scheduled in both markets. We also completed our first implant in Russia at the end of June and expect a second surgery later this year. We continue to be excited about the long-term prospects for these markets and are working with authorities in each country to secure a full product registration along with funding and/or reimbursement. In the U.K., things are progressing with the NHS England Commissioning through Evaluation or CtE program. And our current expectation is that the first implant will not occur until early 2018. We remain confident the government will fund 10 implants. We also continue to pursue reimbursement for additional regions of Italy as well as national reimbursement decisions in Turkey and Belgium. On R&D front, 14 current Argus patients have been tested using advanced retinal stimulation techniques with promising results. Keep in mind, this testing is conducted in the lab using the computer to directly drive the implant and bypasses the current Argus Systems' glasses and much of its software. We are now incorporating the most promising algorithms into the actual Argus System via software changes and will begin testing of patients later this year. We have submitted a protocol to the authorities in Germany requesting approval to begin a clinical trial treating better-sighted RP patients with the Argus technology and hope to start enrolling patients before year-end. We are also awaiting a decision by the authorities in England for expanded testing of subjects in the company's dry AMD feasibility study. As a reminder, we want to test the advanced retinal stimulation techniques I just discussed with the AMD patients in order to measure benefit. As you can see, we have multiple shots on goal to significantly expand our addressable market. We remain on track with our Orion project. As previously discussed, we completed our IDE submission to the FDA last month and we will complete the Orion feasibility submission in Europe this week. This groundbreaking technology holds the potential to restore useful vision to millions of patients worldwide who are blinded by nearly all currently untreatable causes. We anticipate implanting our first Orion in human subject later this year. I'm very pleased with our R&D and clinical execution in the first half of 2017. We achieved all of our major internal milestones and look forward to continuing to execute in the second half of 2017. On the commercial front, our implant volumes are growing, we've expanded reimbursement coverage, and we've entered three new markets this year. With momentum continuing into Q3, we are confident that we will meet our objectives for the year and be well-positioned for 2018 and beyond. Before taking questions, I'd also like to thank Tom for his hard work and dedication to Second Sight's mission. Search for a new CFO is progressing nicely and we hope to have a replacement for Tom named in the near future. In the meantime, Tom remains actively engaged and is prepared to assist with the transition. With that, I'll open the call for questions. Operator, please proceed with the instructions.
