Thanks Tom. Q2 was another challenging quarter for implant volume and revenue. Our US business rebounded slightly from Q1 but was still below historical 2015 levels, if you will recall our selling price was approximately $50,000 over expected Medicare reimbursement for much of Q1. When it became clear CMS did not intend to adjust 2016 reimbursement, we began discounting our technology in late February. We then started revising some purchase agreements and encouraging customers to restart the process of assessing potential patients for Argus II eligibility. We did regain some momentum in the latter half of Q2 and ended the quarter with four US implants. We also had positive change in Q2 in the North American field team with a new commercial VP coming up to speed while simultaneously recruiting a new East Coast sales director. As the new team is coming together a few exciting opportunities have emerged and one in particular is our revised Centers of Excellence program or COE. In the coming months we'll be formalizing exclusive original partnerships strategically placed across North America. This will involve expanding our mutual roles with many of our existing customers and it will be the lead criteria for us as we continue our expansion. The goal of this program is to establish implanting centers and physician clinics that are more intimately knowledgeable, self sufficient and confident. This will be further supported by the added resources we will provide these centers. As a result we expect them to be able to treat a higher volume of patients. Our established COEs will also address several opportunities for growth one of which is the significant number of eligible, motivated patients who are otherwise on hold for a variety of reasons. This includes many prospective patients who don't have access because they would need to travel 200 miles or more to a center for screening, for surgery and for post surgery programming. And after that they need to go through extensive rehabilitation to learn how to use their artificial vision. Even if the patient believes they can overcome the distance problem it's not uncommon for the physician or center to put a surgery on hold until there is a satisfactory solution for the patient to obtain rehabilitation locally. A high priority over the next six months is to build a stronger network of post surgery support, provide much higher number of qualified eligible patients can move forward with an Argus procedure. In addition to our COE program we have greater impact today on the information that is most helpful and relevant to prospective patients as they make their decisions to move forward with the surgery. We're integrating a market leading automation platform that will allow, that will enhance our efforts to communicate with our expanding patient database. This new platform will help us to keep prospective patients updated on the information, provide ongoing support and when appropriate connect them with one or more of our COEs. We are very confident that our efforts to strengthen these relationships with the centers of excellence and prospective patients will lead to an increase in the number of patients treated in the US. In Europe, Middle East and Africa or EMEA we had a total of seven implants during Q2. This was below our 2015 average but recall that many of the markets managed by the European team are inherently lumpy due to the small size of our business. We have seen some recent activity from competitors in Europe and it's possible that we've lost a few cases as they recruit patients for regulatory and or reimbursement approval trial. We expect the European competitors near term impact to be limited by their lack of long term clinical evidence and reimbursement coverage. As in the US we've also made a few organizational changes and additions including a new head of international sales for indirect markets. Speaking of indirect markets we announced two new agreements today. The first agreement is in Taiwan, with Orient EuroPharma a well established distributor deeply connected in the ophthalmology market. Taiwan is a densely populated state of 25 million people, the healthcare system is one of the most advanced worldwide with a structured social security system managed by the Bureau of National Health Insurance. Our second agreement is in Iran with [indiscernible] a company with a proven track record of introducing similar medical devices and building multimillion dollar businesses. Iran is a large market with approximately 80 million people. The department of treasury has granted us approval to sell our product in Iran and the next steps in both markets is to pursue regulatory approval and secure reimbursement or other sources of funding for Argus implants. As Bob mentioned some really good news, though not final yet is that on July 6th CMS posted the proposed rules for the 2017 Medicare hospital outpatient prospective payment system establishing a proposed Medicare hospital outpatient rate of a $150,000 for the Argus II and the associated surgical implantation procedure after hearing comments from various stakeholders including hospitals providing the service and reviewing the 2015 hospital claims data we're pleased that CMS has proposed this new payment rate and the associated new technology APC. Along with other stakeholders including our hospital customers we will be submitting comments to CMS in this regard by September 6th 2016 which is the comment deadline. As with all proposed rules they are subject to change and there is no assurance that the payment rate will remain at a $150,000. We anticipate the final rules will be published in November 2016. Also want to note that this proposed rule only affects Medicare fee for service payments to hospitals and does not directly alter Medicare advantage or private insurer payments. Along the topic of US reimbursement, we also recognize the need for a mechanism for the clinics to build their charges for programming services in connection with Argus II. There a simple amount of work that is performed by highly trained healthcare professionals to ensure that the patient is experiencing the maximum benefit of advice and we believe this should be reimbursed. In June we submitted a category three, CPT code application for programming services in the US. If approved AMA CPT will publish the code in the January 2017 CPT code book and it will be effective January 1, 2017. During Q2 we continued to make progress towards obtaining reimbursement in the UK. As previously announced Argus II is being considered to be funded under commissioning through evaluation, such programs generally known as coverage with evidenced development are becoming increasingly common in major EU markets and allow for conditional reimbursement for innovative breakthrough technologies and procedures such as the Argus II for more long term data is collected. The detailed arrangement and the timetable for a final decision have not been announced but it is likely that this will take place later this year. We're encouraged by the progress in the UK and we'll keep you updated. As announced this past Thursday we are very pleased with the five year data from the Argus II clinical trial has been published in the medical journal Ophthalmology. The paper entitled five year safety and performance results from the Argus II retino prosthesis system clinical trial follows the assessment of the original 30 subjects who were implanted with the Argus II in 10 clinical centers in the US and Europe. As part of the study three types of visual function tests were performed using computer run assessments. Square localization or object detection, direction of motion, or motion detection, and discrimination of oriented gradings for visual acuity. Two types of real world orientation and mobility test were also performed. A test where patients were asked to locate and touch a door and a test where patients were asked to follow a white line on the floor. The long term results were compelling and present a milestone in the fight against blindness. It's extremely gratifying for us to know that the benefits reported by patients receiving the Argus II endure for many years after implantation. As European competitors start conducting cases in order to obtain regulatory and or reimbursement approval, we’re convinced the long term data supporting the Argus II provides us with a significant competitive advantage into the foreseeable future. One final reimbursement note, now that our five year data is published we will be reengaging many of the US Medicare administrative contractors or MACs in non coverage jurisdictions with our key opinion leaders in order to influence a favorable coverage decision. I am hopeful that we could see additional favorable coverage decisions later this year or sometime in 2017. Our research and developmental efforts remain focused on several key areas, first developing enhancements to our Argus II technology to increase patient satisfaction while improving outcomes. Second, conducting additional clinic work to expand the patient population we serve and finally expanding into direct cortical stimulation with the development of the Orion 1. We’re investing in Argus II enhancements that we believe will allow current and future patients to enjoy better more useful vision utilizing the current implant. As discussed in past calls we continue to focus on improving the externals including the eyeware, the camera and the video processing unit or VPU. The new more powerful VPU facilitates more sophisticated software enhancements and an improved user interface. We are on course to file for FDA approval and CE mark regulatory clearance for next generation platform externals around the end of the year or early next year. We will begin patient testing of the new software and filters such as improved contrast or edge detection, new stimulation strategies and soon before the end of 2016. Commercial roll outs of these exciting software enhancements on the new platform are dependent on the outcomes of testing and additional regulatory approvals. We are continuing to evaluate Argus II in populations of low vision patients, such as those with dry AND, some initial data from our AMD feasibility study were recently presented by a Professor Stanger from Manchester in the UK at a prestigious conference in Bordeaux, France. The presentation attracted a great deal of interest from many of the surgeons in attendance. Professor Stanger reviewed safety data, the preservation of patients' native vision and the ability of patients to integrate their new artificial vision with their native vision. The focus moving forward is to better understand the resolution and usefulness of the combined vision. We are pleased that this work is gaining exposure and generating discussion. As we continue to evaluate all the data on patient performance we'll have more detailed information concerning our path forward. We also had the first implant of Argus II in a Stargardt's disease patient in Florence Italy by a Professor Rizzo. The surgery went well and the patient is beginning the rehab program. Some Stargardt's patients are within our European label and if results look favorable we expect interest from additional patients in this treatment. Finally as discussed by Bob the Orion program which allows us to leverage our Argus technology and expand into direct cortical stimulation continues to progress. We're starting to expand some of the preclinical arrays and we'll be analyzing histology in the coming months. We remain on track to submit an IDE to the FDA around the end of the year requesting approval for starting human feasibility study in the first half of 2017. Overall I am encouraged by recent events. The rights offering and the potential for a higher Medicare outpatient payment rate for 2017 will enable us to continue efforts to build awareness and provide Argus II to those in need. Similarly our restructured sales teams will leverage their deep experience and should drive the rebound in second half of 2016 implant volumes. Our position as the dominant industry player reflects our extensive patent portfolio protecting our work our ongoing technological investments and the growing evidence of the safety, reliability and longevity of our products. Thank you for your continued interest and support. With that I’d like to open the call to questions. Operator, please go ahead with the instructions.
