Thank you, Lynn. Good afternoon and thank you to everyone for joining us. We are pleased to report another outstanding year for AtriCure. 2015 was marked by strong growth and operational execution across all areas of our business. Our technologies and therapies continue to provide treatment to patients with the most serious forms of atrial fibrillation. During 2015, over 25,000 patients were treated with ablations and almost 23,000 atrial fib devices were implanted. We completed the integration of Estech, acquired nContact, hit several key milestones in our clinical trials, incorporated CONVERGE IDE into our clinical trial program, and significantly expanded our professional education programs. We also released two new products to the market, a cryoanalgesia therapy for pain management and the cryoFORM, cryosurgery probe in the EU. In October, we moved into our new facility in Mason, Ohio which was designed to support long-term growth and to enable more collaboration across the business and with our customers. The new facility has exceeded our expectations across all fronts. Our accomplishments throughout 2015 positioned us to accelerate sales in 2016, and we are reiterating our top line guidance of 25% growth for the year. Our fourth quarter revenue reached $35.9 million, up 22% from Q4 2014 or 24% on a constant currency basis. Growth was predominantly powered by sales in the U.S., which were up 31% year-over-year. Domestic growth was driven by ablation related open heart products, ablation related minimally invasive products in the entire AtriClip portfolio of LAA management products. International revenue was down 5% compared to the fourth quarter of 2014 but up 4% on a constant currency basis. This decline was driven primarily by exchange rates and weaknesses in select distributor markets, particularly China. Moving on to our business trends. The AtriClip product line remains our fastest-growing franchise, and…

Thank you, Mike. For the fourth quarter of 2015 revenue increased 21.9% on a GAAP basis to $35.9 million. On a constant currency basis worldwide revenue increased 24%. Revenue from product sales in the U.S. was $28.9 million an increase of 30.7% from the fourth quarter of 2014. Revenue from open chest ablation related products in the U.S. increased by approximately $2.3 million to $14.5 million representing growth of 19.2% driven by our education and training efforts as we build the still underpenetrated market for concomitant surgical ablation. U.S. sales of products used in minimally invasive procedures increased approximately $2.9 million to $7.1 million or 67.2% and influenced heavily by the contribution from nContact product as expected. Continued development of clinical data and support of MIS ablation for the treatment of Afib through trials such as our DEEP and CONVERGE PMA studies are critical to growing this market. U.S. sales of the AtriClip system during the fourth quarter of 2015 were $6.7 million as compared to $4.8 million for the fourth quarter of 2014, an increase of 38.2%. Growth was again strong for both the open and MIS clips. International revenue of $7 million was down 4.6% on a GAAP basis and up 3.8% on a constant currency basis as compared to the fourth quarter of 2014. In addition to the currency pressure in our European markets we experienced some weakness and sweetness in certain markets primarily China. Valve tool sales totaled $700,000 worldwide with approximately $600,000 in the U.S. and $100,000 in the international markets. This was down $300,000 from last year. Gross margin for the fourth quarter of 2015 was 71.2% as compared with 69.4% for the fourth quarter of 2014. The primary driver of improvement was the higher concentration of sales in the U.S. along with a…

Thank you, Andy. To wrap up, I'm excited about 2016 and beyond. In the current year we are working hard to ramp up our clinical trials starting with DEEP and CONVERGE and bringing new products to market for the AtriClip franchise. Additionally, we expect CRYO and nContact be big contributors in the back half of the year. As Andy mentioned, we remain confident in our guidance for 2016. We will start the year sequentially flat from Q4 and end the year strong after nContact is fully integrated with expected 25% top line growth for the year and a path to EBITDA profitability in 2018. We are also maintaining our long-term objective of 18% revenue growth. By the end of the decade our goal is to be the recognized leader in Afib and appendage management and to have improved the lives of more than 500,000 patients. As we look forward, I am more excited about our business than ever before. We have a terrific team assembled here at AtriCure and we will continue to advance the treatment of atrial fibrillation. We will now turn the call over to questions.

Thank you. [Operator Instructions] Our first question comes from the line of Matt Miksic from UBS.

Hey good evening. Thanks for taking the question. I want to just followup Mike, if I could on -- you mentioned training and you've talked about it before as an important driver. If you could talk a little bit about, you know just walk us through maybe what you are expecting this year in terms of contribution, just if it is from training from last year or how we should think about the investments you make in this year, just any kind of light you can shed on that as an important growth driver, and then I have one follow-up?

Well, we don’t really talk about the specific revenue that’s tied to the training education programs. It is really about getting more and more patients treated. Historically, we have seen procedure volumes go up between about 40% and 45% overall in the areas that have actually come to our advanced training courses. This year, we'll do another 10 or so of those advanced courses, about one per month or so. In those courses, we get about 15% to 25% and actually recently we've had as high as 35% or 40%, which is higher than we normally like to have at those programs. But the training programs have been excellent. They continue to get better. We actually have people coming back for repeat trainings at this point because they are starting to build a network on their own working together, talking about the different cases that they are approaching whether it be an MVR, an AVR, or a CABG case, and they’re really kind of beginning to kind of build a whole network of how do we treat these, how do we work together to get that number up, and we’re seeing a lot of increase in the procedures from that standpoint. So, we believe that the training is obviously absolutely critical. Now that’s one angle to the training. In addition to that, we have also got the James Cox Fellowship Programwhich is getting at a much earlier stage to send people over for three months to sites that are doing a very high percentage of their cases. Everybody that’s really included by AATS in that is over 75% of the patients that will walk in the door that have Afib are getting treated. So, it’s really kind of setting the stage for future of surgeons that are going to be treating everybody that walks into the OR that has Afib that should be treated, getting treated. So, we are constantly looking at different ways to train on that front, and we're also seeing many more case observations. We have to open up more and more sites around the country. We've predominately been on the East Coast on that, and we’re starting to open up West Coast sites as well and that's actually been increasing quite substantially over the last couple of months.

Understood, that’s very helpful thanks for that, and just one if I could on the cryoprobe, and with the introduction coming some time during the year, if you could talk about may be what the mix of that product could be, what your experience with it has been so far and what we should expect over the long term in terms of mix of your business?

We’ve seen in the cryoprobe if you just - we’ve got and this is more of a reminder. Today, on the market in the U.S. we’ve got a CRYO2 Probe and CRYO3 Probe. The CRYO2 Probe is really the catalog probe. It is the stiffest probe that we have, creates incredible great transmitter lines, very stiff, not as bendable as the CRYO3. We introduced the CRYO3 Probe in the late 2014 and that really helped power a lot of the growth in 2015 around the CRYO platform, because you could use it in more minimally invasive settings, people could use it more easily, bend it, and it was a great probe that was used. From that, we actually saw an increase and it grew at a faster pace than our clients did north of 30% on the growth rate for the CRYO side of things. So, we saw nice growth that came off of that overall. Now what we are doing is the CryoFORM, in Europe we just rolled it out in the fourth quarter after getting the approval over there. Again, we anticipate here in the U.S. that’s an even more flexible probe, and then with that probe we anticipate that we will be able to continue to grow the market even more. So, any probe all used for different reasons in the market.

So more competitive with the new probe, I guess is what you are seeing in Europe and what you would expect in the U.S.?

Yep.

Great, thanks so much.

Thank you. And our next question comes from the line of Danielle Antalffy from Leerink Partners.

Yes, hi good afternoon guys. Thanks so much for taking the question and congrats on another great year. Mike, I was wondering if you could comment on some of the momentum we saw in Q4. It looks like U.S. open ablation, and AtriClip sales accelerated actually in the quarter, this is for four new products, well can you talk about what drove that? I assume some of it is training or maybe I'm missing something here, but so what drove it, how sustainable is it going forward?

Yes, I mean on both the open and the -- at the open side of the business. The open side of the business, we continue to see a long run way for that product. We’ve talked about it here where we anticipate that portion of the business growing at 15% to 20% on an organic basis from now through the end of the decade. We continue to feel that as we kind of march down that pathway of getting more and more patients treated, that’s the right growth rate for that particular part of our business. Training and education awareness play a critical portion of that, which is why we keep doing it. Some of the items I talked about in Matt's question relative to putting in the sponsorship that we are working with AATS on training people at a very young age, starting to work with academic institutions at residency programs. Those are some of the things that we’re looking at. And so yes, that definitely helps drive some of that open side of things for sure. Number two, I think in terms of the clip side of things is, there is just more awareness out there for managing appendage being a positive thing and people know that the product works. So the product works incredibly well. We’ve got great feedback on that. We’ve got over 65,000 implants today, and with that breathes a lot of confidence, and as people use it more and more, they realize how simple and easy it is to use. They test it when they are actually in the OR. They’re getting imaging afterwards, and they’re seeing good closure with it, so they’re feeling really comfortable and confident with it, and that is actually helping drive adoption as well.

And just a follow up on that, how much of the growth in both of those areas is new folks at existing centers using it in their procedures versus existing users that is using it more frequently, I guess if you have that level of visibility?

I wish I could tell you that I’ve got that exact level of visibility. What I’ve got is kind of conversations and the feedback we’ve gotten from the field, we don’t actually track it by user. We track it by site. We have continued to see the number of sites growth substantially over the past. Every quarter we’re seeing the number of sites of ordering clip grow. So it’s definitely new sites. It is surgeons within a site that are building it and working with our teams and then also people that started out by doing it for on-pump and then decide wait I can do this instead of cutting and selling and save myself 10 minutes. It is across the board mix between those and to give a specific percentage would be much more of a guess than anything else.

Okay that is fair and then last question from me, internationally you mentioned some weakness specifically in China, obviously lots of volatility in some of these international markets. I was just wondering if you could comment on what is reflected in your guidance from a macro perspective? Is your guidance assuming some continued weakness there or is there potential downside, further downside from that?

On the international front, we’ve got a bunch of tailwinds quite frankly on a positive side coming into 2016. 2015 was a little bit of a disappointing year overall growing on a constant currency of 12.5%. We are definitely hoping for than that. With the exchange rates remaining relatively constant for this year, we anticipate to see a greater growth rate than that 12.5% to get closer to the organic numbers that we had talked about before, kind of the long-term organic numbers, we do see a little bit of an uptick on that. What is driving that is a couple of different things. Number one is, in Japan as you saw earlier in the year and I did not mention it in my comments and probably we should have, but we got clip approved to sell in Japan and we are looking forward to getting reimbursement in that market as well here fairly soon, likely by the third quarter or early part of the third quarter is the target for that. That should help drive the Japanese market quite substantially because we don’t sell the clip there today. On top of that, we’re looking to get some CRYO into the Japanese market by the end of the year as well. So we’ve got a couple of really good pieces that we’ve been working on for three years or so to kind of get into the Japanese market which is our second largest market in the world. As I mentioned China was little bit soft in the fourth quarter. The first three quarters were actually fairly good and we are rebuilding the relationship and things we have got with our China distributor there. So we anticipate that actually it will kick off the year very strong and that we should see some stronger growth in China than we saw in last year as well. So I don’t see a lot of downside per se from that number from this year and I see that we actually have some upside into the guidance that we've got there.

Okay. So it sounds like the international business is not contingent upon any sort of macro conditions, it is very new products driven?

No, not at all.

Great.

And we think on many of the areas that we saw pressure through much of the year, which were a lot of these Eastern Block countries I would say in some of the distributor markets that were a little bit tighter just with the economy and what happened there we kind of - we hit some lows there that we pretty much have to come up because there is not much to go down from in those markets today.

Okay, that is helpful. Thank you so much.

Thank you. And our next question comes from the line of Jason Mills from Canaccord Genuity.

Hi this is actually Jeff filling in for Jason. Two quick questions from me, first wondering if you could provide any or if there are any unique quarterly trends in the business in this year that you would, investor should be keen to, I appreciate the commentary that Q1 will be flat, but is there anything else that we should be aware of in terms of gross margin or on OpEx?

No I think that you will see that a lot of the heaviest loss in the first quarter like we said it will be flat sequentially from Q4 to Q1 and then ramping as the year goes on. As people on our team we just rolled out commission plans, the team has just got everything in terms of their coders for the year in the January timeframe that included all the products, we did not have it at the end of last year after we bought nContact. So as they get used to selling positioning and working with that product and better understanding it, we anticipate the back half of the year to see some substantial growth in that part of the business.

Great thanks and my second question, I was just wondering your open business blew away [ph] expectations and I appreciate the importance of training and awareness here. Looking ahead, I am wondering if you could give us an update on the procedure side on the open market and the opportunities there going forward?

Yes, we continue to see the open market as I mentioned is a really strong grower in that 15% to 20% organic growth from now to the end of the decade. That helps us get comfortable with the 18% overall long-term growth that we talked about with Clip being above that 20% number, we've kind of talked about on that call before as well. So what is driving that is just more and more people are now realizing the benefit of treating and the more that they get trained on the more they come to the training and more they are seeing their colleagues do it and get better results with these patients, the more you are starting to see people say, wait I have got to treat on every single patient that comes in the door. So they are kind of moving down that pathway that we've talked about. It doesn’t happen overnight. Some products you can overnight just flip a switch and all of a sudden start putting something in. With this it takes time for someone to develop full comfort with doing the complete Maze, doing it in all of their cases whether it’s an AVR, a CABG or mitral valve and we’re starting to see growth in all of those different areas of our business across the board. And so I would say that, the biggest issue is that we are still less than 25% penetrated around the globe and we see growth in all three of those different areas.

Great, thanks for the color. I will get back in queue.

Thank you and our next question comes from the line of Rick Wise from Stifel.

Hi guys it’s [indiscernible] in for Rick, just a couple of questions, so first I just wanted to start on your ATLAS trial. So I think there is such renewal up to 2000 patients which follow up through 365 days and on the call you have talked about a quick enrollment and possibly have a data sometime in 2017, but just wondering with that could we positively see initial data or presentations before 2016 and maybe on a 30 or 60 or 90 day basis for the patients?

We don’t anticipate putting much out from a data standpoint before 2017 some time. So I would say that, well I know everybody would love that data in advance of that. Really the focus is going to be on getting all the data right, reconciling it. My experience of clinical trials is you've really just got to make sure that you have got this data right that you understand cause or you've got double reads on them, et cetera. So it will likely be 2017 before we get data.

Okay, got you and then I know AtriCure has been supportive of WATCHMAN approval and reimbursement and in the MCD one thing that we found interesting was adding cardiovascular surgeons as potential operators to the guys that are doing mitral, aortic and CABG cases. So just in your surgeon conversation I know the MCD is only a few weeks old, but have you seen kind of a light bulb go off on the or over the heads with them thinking, hey I can manage non-valvular AF patients now. Why am I not managing the valvular AF patients with atrial fib?

I don’t think that we have seen the light bulb or any of that kind of go off at this point. What we have seen over the last two years is that as there has been more and more talk about WATCHMAN and all the different trials and the data has just come out from them in terms of managing the appendage, they begin to draw off to the conclusion that they need to manage the appendage in everyone of these patients and so we are seeing that more and more. I mean one of the reasons we are supportive of it is because we think managing the appendage is the right thing to do and we are starting to see more and more surgeons get there. But they are kind of getting there by attending different conferences, talking to their colleagues in cardiology and on the EP side, interventional side now and so there is more talk at the hospitals. That’s been going on, there wasn’t one light bulb that happen with the new approval from CMS.

Okay and if I can just make one last and I’m sorry if I missed this, but did you guys give the individual growth rates for AtriClip and for Pro?

No we didn’t give them, but they were for the quarter drew open was north of 30% and MIS was around 59%.

Great, thanks guys.

Under 38, yep.

Thank you. And our next question comes from the line of Tom Gunderson from Piper Jaffray.

Hi, good afternoon everybody. So Mike, I was just going to ask about Japan and AtriClip, you touched on that a little bit in a previous answer, but maybe we can dig in a little bit for your guidance for 2016 was there any assumption on a Q3 or Q4 reimbursement approval for that? And second maybe just a little color on how the Japanese are treating or managing the left atrial appendage right now?

Yes, so the color right now many of them are doing cut and so or they are not treating it at all and I’d say that would be the predominate, I mean so you are kind of getting mix of that, not much different than what you see in the U.S. The markets are actually reasonably similar from that standpoint. In terms of kind of as we look at the year we do anticipate and we have got a modest amount in our numbers in the back half of the year relative to getting the approvals on that. So we definitely have that as part of the international growth and some of the growth we’ve got a combination of the Clip and the CRYO that give us confidence in the overall 25% number.

And then as I read the ATLAS press release I was, maybe I was just viewing it through my own distorted lens, but it seemed to lend itself well to hospital issues, costs, expenses et cetera. You are going to be capturing that as well as the events and as you gather the data on this randomized trial?

Yes, that’s one of the biggest reasons that we’re doing the trial is to actually figure out what does it do for hospital resource consumption. The idea behind this trial is with these 2000 patients it will lead to other trials. We’re going to learn a lot from the prophylactic treatment here of the appendage and so we are going to kind see what the results come back both on a symptom basis as you kind of talked about, but also on what resource consumption. So we’re tracking all that at 30 days, at one year are they going to be coming back for re-hospitalization et cetera and so that’s a big part of the trial and then that will help us design the next trial that may lead to something much bigger.

Got it. That’s it from me and thanks.

Thank you. And that concludes our question-and-answer session for today. I would like to turn the conference back over to management for additional comments.

Great, as always thank you for the great questions. Thank you for participating on the call and your interest in AtriCure. Have a wonderful evening.
