Martine A. Rothblatt, Ph.D. - Chairman and CEO: Thank you operator. Good morning everybody on the conference call. I am joined this morning by John Ferrari our Chief Financial Officer, Roger Jeffs our President and Chief Operating Officer and Andy Fisher our Chief Strategy Officer and individual in-charge of legal and Investor Relations. I'd like to start by making a few introductory remarks and then welcome any questions that could be directed to Andy, Roger, John or myself.

The press release that we issued this morning certainly make this about as joyful a quarterly and annual conference call, as any CEO could ask for. We're reporting a record revenues, record profits per share, so across the board it's just been a fantastic quarter and a fantastic year for United Therapeutics. Our excellent annual results reflect both our leadership in pulmonary hypertension medicines and our discipline in focusing Company resources on transformative growth opportunities.

One of the things which is especially noteworthy is that as of the end of 2012, our medicines are now being prescribed to more pulmonary hypertension patients in the United States than any other companies medicine, that's a high watermark that we've achieved after our several years striking about against other companies, which are much larger and better capitalized than we. I think the reason for this is completely due to the fact that physicians over time have found that the United Therapeutics medicines are the once that they rely on to provide superior results for their patients. Let me briefly mention what those medicines are. Briefly mention some of their key highlights, and then say a word or two about our pipeline and then move into question-and-answers.

Remodulin is a medicine which continues to grow now, even though we're actually in the 10th year after its approval, but is in a way like a – kind of a version of a human being that they keep growing until they get to sort of the tween period and then they just really burst out into becoming a full potential young adult, and that's what you see here with Remodulin, it's the medicine that physicians reach for when patients are struggling with managing their pulmonary hypertension due to the oral treatments not being able to halt the progression of the disease. It's interesting, I was in conversations with a leading physician the other day, and he said to me, Martine I know that the name Remodulin has nothing to do with the fact that it seems to remodel the patients' vasculature, but that is what it seems to do, and that was just that physician's point of view, but it has certainly allowed our patients to live a much more vigorous life style than would be the case if they were not on Remodulin.

Now, what does Remodulin have going forward? Well, it's really exciting, because what we have right now is a point where Remodulin is on the cusp of being approved in China, it's about a year or so from being approved in Japan and intravenous Remodulin which generally doubles the number of patients who take Remodulin above subcutaneous Remodulin has just been approved in Europe, and now we're getting country by country to pricing approvals necessary for us to being commercializing it. So, we definitely expect a nice surge in Remodulin revenues from both the international opportunities for Remodulin as well as a continued confidence in physicians that the earlier they give patients Remodulin the better chance there is of perhaps having some favorable (indiscernible) of the pulmonary vasculature.

Now let me move into Tyvaso. Tyvaso is really like a horse that you see at the races who's right behind the lead horse. Pulls nose-to-nose and then pulls ahead. And it's been exciting for us here at United Therapeutics to watch Tyvaso gallop closer and closer to Remodulin right now Tyvaso is literally nipping at Remodulin's heels and it doesn’t really take a great expert at drawing of lines of growth to see that we are somewhere between 12 and 24 months for Tyvaso to an all likelihood surpassed Remodulin's revenues and become the number one revenue generator here at United Therapeutics.

Now that’s really exciting for us because one of our kind of mantras that we have here in the company and is driven by our desire to always make life better for the patients is to make the older therapies seem to be relatively barbaric compared to the newer therapies and to always try to go for the next. What is the next-next. The therapies that we are work in the last decade, we are not a company that rests on those laurels we are one that constantly pushes the ball forward. So with Tyvaso if you are going to offer a patient who is otherwise be a catheter 24 hours a day and it's a hell of a lot better than being in the bed and these patients are able to things from skiing and snowboarding our one patient ram so may or you name it but if you say that what would you rather do be on a catheter 24 hours a day or take for 2 minute inflation session a day, I mean everybody would choose the latter and this has taken a number of years for physicians to gain comfort with Tyvaso, having that kind of potency, because they have looked at Remodulin as the gold standard for so long have been very cautious about taking a patient to might otherwise to be prescribe Remodulin and instead prescribing and something which is such a different therapy like Tyvaso.

But it's a conservative field of pulmonary hypertension and now it's a 2010, 2011, 2012 going forward we have now reached a point that there is critical mass of physicians, that will reach first for Tyvaso whereas they were previously perhaps which first for Remodulin and that's especially true with regard the patients earlier and earlier in the disease process, the early New York Heart Association Class III patient even some of the late New York Heart Association Class II patients.

Physicians are gaining comfort with the fact that when you combine a PDE-5 inhibitor and then ETRA with inhaled Tyvaso, we are going to get a superior result. So, we are just really excited at this galloping of our revenues on Tyvaso and the trend lines, which are lead to it becoming our number one revenue producer within the next 12 or 24 months or so.

Now, let me speak about Adcirca. Adcirca is really something, it's a drug that was launched into competition against Pfizer and Pfizer had a very aggressive detailing for us on the world's bestselling drug, Viagra which was rebranded as Revatio for pulmonary hypertension and despite that effort, we are of course a small biotech Company and nowhere near the resources of Pfizer, yet our great partner Lilly had faith and confidence in us and gave us all manner of scientific and clinical trial support and as a result of that, we have the data that has been able to demonstrate to physicians that they are better off putting their patients on Adcirca than Revatio. And that data starts with the fact that Adcirca needs to be dosed just one time a day compared to Revatio or its generic form, sildenafil, having to be dosed three times a day, but when you're dealing with a life threatening illness, with patients having just a few years of life, this is not a place to pinch pennies and hoping that the patient will remember their middle of the day and the end of the day dose, because if they don't, there will be serious consequences for the patients' health. So given the relative affordability of Adcirca in the first place, it's not surprising to me that, just to share with you some data I got from just in January, we crested 12,000 prescriptions written for Adcirca in January, which is at the highest ever, and many people believe there is something like 25,000 patients with pulmonary hypertension.

That means almost half of all patients are prescribed Adcirca alone, not to mention our other drugs, and I am really very pleased that our sales and marketing teams see this, not as a resting point but as a launching pad and indeed our goals is to continue to bring the benefits of Adcirca to the physicians until we can hit 15,000 and even 20,000 prescriptions for Adcirca in the coming years. I promised to say couple of words about our pipeline, let me just highlight two programs in particular.

I'll touch actually on three because I didn’t really complete the story on Remodulin as deferred. Remodulin has in addition to its international sales potential, it has a new sales potential that’s about to pop out through the miracle of some technology called implantable pump technology. This technology has miniaturized the type of outside the body pumps that our patients wear until they are so small and so, and made of such materials that are so bio compatible with the cardio vascular spaces of a human that they can be implanted inside the body in an outpatient minimally invasive procedure implanted inside the abdomen I'm sorry. And continue to gradually seek our Remodulin out of a tiny specialized catheter built into the device 24 hours a day, 365 days a year. So we expect to fully enroll, we have already fully enrolled our pump program with Medtronic and we expect to report the results of that out in august of this year. By the way little sign of how well that study is going the original target date to report the results was October, then it was September and then it was August. I have never experienced something like this in my years as a drug developer, a program that was ahead of schedule, and a clinical trial that was finishing sooner, and the reason for this is that the duration of this implantable pump program is based on accumulation of a certain number of years, of patient years of safety, and there have been so few dropouts from the implantable pump program. They have predicted that there would be a certain number of dropouts that would result in October, but there've been so few that we are now scheduled to accumulate all the safety data we need by August, which is absolutely remarkable, and I have heard the stories from the patients, and certainly, not a surprise to me why they would – nobody would want to dropout. It's a life giver backer to the patients. The patients say, our lives have been given back to us. We have no pump outside our body, no catheter, this implantable thing – I visit a doctor once every one to two months, depending on the patient. They fill it up and good to go. It's really remarkable. So that's in our pipeline, but that should be popping into commercialization in late 2014, early 2015 time frame.

The other two things I really wanted to mention is oral treprostinil, which we continue to be very, very excited about. We've got a gain buster clinical trial going on right now. We're enrolling over 850 patients. All of the major pulmonary hypertension centers in the world are participating in this study. We believe it's going to result with a statistically significant outcome, showing a delay to clinical worsening when oral treprostinil is dosed in combination with other drugs, which will certainly validate the blockbuster potential for that drug.

In the meantime, even as for monotherapy, we have our filing before the FDA accepted resubmission, as many of you have seen in the previous press release, and that's pending FDA review right now. Of course, those of you who have been UT watchers or I may say Unitherians for a few years, we have a policy of not commenting on matters that are under FDA review. We certainly are going to extend that policy to cover oral treprostinil at this time.

The second big exciting thing in our pipeline is the TransCon treprostinil program. This program we announced several months back. We've had some fantastic progress on the chemistry, manufacturing and controls side of that project. That project will allow us to ultimately take the magic of our Remodulin and reduce it when combined with a couple of additional molecules to a once-daily, 10-second injection, subcutaneous, no side pain and get the benefit of a zero order release of treprostinil over a 24-hour period. This is a therapy which is so transformational, it's exactly what I mean in the press release when I talked about transformational opportunities that it actually harkens to the day when all pulmonary hypertension patients will be able to avail themselves not only treprostinil, which is great, but a zero order release delivery of treprostinil, meaning like a level dosage of it in their bloodstream 24 hours a day, which is the best of the best.

So with those introductory remarks, let me now open up the phone lines to any questions to Dr. Jeffs, John Ferrari or Andy Fisher. Operator?

Transcript Call Date 02/26/2013

Operator: Mark Schoenebaum, ISI Group.

Mark Schoenebaum - ISI Group: Could you just maybe explain to us, why you made a decision to refile the oral treprostinil NDA if that’s possible to comment on that?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: That to me is a favorite topic. I think really that to not refile would be the absolute worst decision I might have ever made as CEO of the company. We are talking Mark, about a molecule that has been a life saver for thousands of patients. It’s the key pharmaceutical ingredient in Remodulin it’s the API in Tyvaso. In all of its clinical trials it resulted in P values which were either statistically significant in the case of the FREEDOM-M trial or very close to statistical significance in the case of the FREEDOM-C(1) and C(2) trials. As I know you know very well Mark when you are very statistical significance 0.05 is not some kind of like you know magic marker in the sense that a drug definitely positively works if it's less than 0.05 and definitely positively it does not work if its above 0.05, its instead of regulatory sort of line in sand, and can be somewhat of a shaded line in the sand depending on compelling factors to take into account, especially for patient welfare. So the p-values for the C-1 and C-2 studies were so close to statistical significance, nobody doubted that the drug works. Nobody thinks that the drug is a placebo, and in fact, when you begin to look at subsets of the patients, it has a dramatic benefit for many of the patients. With regard to the FREEDOM-M data, this drug had a, oral treprostinil, had a better demonstration of efficacy with high statistical significance than Remodulin or Tyvaso did. Again, just what I'm talking about here is the 6-Minute Walk outcomes which were greater for oral treprostinil than for Tyvaso or Remodulin. As you see from our financial results today, Mark, Remodulin is far and away the first choice of physicians for prostacyclin therapy delivered parenterally. Tyvaso is far in a way the choice of physicians for prostacyclin therapy delivered via inhalation, both of them continue to be prescribed by physicians to ever greater numbers of patients. So, of course, we are going to refile oral treprostinil, and of course, we're going to be relentless in getting this drug approved because sooner or later, it will get approved and it will be a great blessing to the patients who have it.

Mark Schoenebaum - ISI Group: What's your level of confidence it will approve. Then I'll drop-off?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: I think that I personally, I'm a believer in the right things and the right outcomes resulting, so long as one doesn't quit and give up first. So my personal belief is that, as long as we persistently do everything which is right and necessary, oral treprostinil definitely will get approved, and I know it sounds kind of silly to say quitters never win and winners never quit, but we are winners here and we're not going to quit on oral treprostinil.

Operator: Michael Yee, RBC Capital Markets.

John - RBC Capital Markets: This is (John) on behalf of Michael Yee. Understanding the need to keep comments in general, can you describe to us the contingencies or outcomes with the patent infringement case with Sandoz, and with the court case beginning, could you just clarify for us when some of the judgments could come, is it before year end?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Sure. Thank you for the question from RBC Capital. I'm going to like, bounce that question over to our patent guru, Andy Fisher.

Andrew Fisher - SVP, IR: Thanks Martine, and thanks for the question, John. Just to review a little bit, we filed a lawsuit against Sandoz about a year ago, after receiving Paragraph IV notification related to their ANDA filing. That case is currently underway and proceeding pursuant to a scheduling order entered by the court early last summer. The scheduling order is available through the court docket system, if anyone cares to review it. It sets a pretty specific calendar, with sort of a specific time frames for different activities to occur. Right now, we're in the sort of pre-Markman briefing phase, and the court, I believe, will hold a scheduling conference in the spring to set the format and timing of the actual Markman hearing which should take place I think sometime in Q2. Following that the calendar specifies things such as briefing on summary judgment motions and for those to conclude sometime in early 2014 and then we'll set a trial date sometime later in probably the mid-2014 time frame, so that’s the general calendar. And like I said everything so far I guess is preceded pursuant to the calendar set by the court. As far as speculating on different outcomes that’s something we are really not going to comment on. I think all of you who are experienced pharma and biotech investors know what the potential outcomes of cases like these are and same rules apply to pretty much every case. We have said from the outset that we're very confident in intellectual property we have protecting this product and intend to enforce that IP vigorously as we proceed through the case.

Operator: Liana Moussatos, Wedbush Securities.

Liana Moussatos - Wedbush Securities: When you received the complete response letter for oral treprostinil it sounded like the expectation was having to redo another trial before resubmitting. When you went back and looked at the data did you see something new that you had not seen before that caused you to resubmit so soon or recently?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Liana, thanks for your question and thanks for your excellent analyst coverage of our company as well over so many years past. As noted, we really don't want to get into discussing internal discussions with the FDA out of respect for the regulatory process and the PH committee in general, but as Roger is in charge of this entire effort, Roger, would you like to provide any overall color that could be responsive to Liana?

Roger Jeffs, Ph.D. - President and COO: Maybe I'll just start with sort of topical response and that in science there are no absolutes and different people going to address the same scientific dataset and reach different conclusions, and certainly that came into play here, then when we got the complete response later that was our first view of some of their science of the cardioveno division scientific inclusions on our NDA submission. Subsequent to that we had a face-to-face end of review meeting in December. Where we were able to respond to the questions and inform them about the rationality of our responses and why the dataset make sense, particularly is an alternative doses one. I think based on that favorable meeting which we think was informative and even didactic it certain period of time a resubmission was thought to be warranted both by us and the division and therefore we did the resubmissions, which was viewed as a complete response to all of the issues that we are getting in the complete response letter. As Martin have said, we won't comment on further discussions to that point, but I think you're correct that most of what we have shown them is perhaps reanalysis or reemphasis on analysis that we did previously and not new data. So, the resubmission was accepted without the need for new data. So I think that's all I'll comment, otherwise, I'll start getting into details.

Operator: Eun Yang, Jefferies.

Eun Yang - Jefferies: Question on Remodulin. So since the Tyvaso launch, Remodulin annual growth has been mid to high single-digit versus in 20s previously. Can you tease out how much impact is due to, decline in annual growth, is it due to Tyvaso versus Remodulin being the choice of product?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: It's an interesting question, and thanks for asking it. I think a certain part of the – it's sort of like what Roger said previously, there's many different ways to view those numbers and so I'm going to give you sort of a 360 degree answer if you'd like, taking a look at the same numbers from different perspectives. First of all, there is a factor of just the law of large numbers at play here and as the base gets larger and larger, incremental revenues are going to grow at a – represent a smaller percentage growth period-to-period. So there's a certain factor of law of large numbers at work here. That factor is not so important when one has a very wide, essentially unlimited or barely capped addressable and capturable market, but with the case of subcutaneous and intravenous Remodulin, we may be coming very close to the size of the adjustable market. Physicians report a certain amount of resistance on the part of patients to putting up with a rigmarole associated with having a catheter either sewn or often painfully inserted into their body, hooked up to a pump that they have to carry around, sleep with, live with 24 hours a day. And in the case of the intravenous Remodulin, comply with extremely stringent infection control and sterility procedures. It's a big burden, and there's no doubt about it. We're dealing with an orphan disease population in the first place, probably just about 25,000 diagnosed and treated patients in the U.S. And of those, the patients who would be willing to put up with this kind of a rigmarole are going to be the most sick of the patients, given that there are other therapies available that can be taken orally. Generally speaking, the most quoted statistic that you'll see is that something like 10% to 15% of the patients are what are called New York Heart Association Class IV. So that would be maybe, let's say, 3,000 patients, upwards of that. And UT Remodulin sales probably -- well, from a dollar standpoint, we probably account for about 75% of the dollar spent on parenteral prostacyclins already. So that's another factor in terms of the growth rate. When you're getting very close to the ceiling of where you can grow, there's not that much -- if you keep growing at double-digit rates, you're just going to crash into the ceiling. So it's natural process, that growth rate slowed down once the room for growth becomes diminished. With regard to the transition between Flolan and Remodulin, there is certain amount of that at play, but there is also certain amount in the other direction. So, I'm not sure, if it's really a factor because it may just be a wash. There are certain number of patients that transition from subcu or IV Remodlin on to Tyvaso and I think that was kind of behind your question if that was the result of some of the diminishment in the growth rate of Remodulin. But there are also certain number of patients that transition from Tyvaso to subcu or IV Remodulin, and I think it's probably a wash there and that factor does not really account for the single-digit growth rate on Remodulin, I think it's more of the law of large numbers and the fact that we're matching out on the addressable demand for subcu and IV therapies. With regard to Tyvaso, you see that therapy galloping forward it's not at the expense of Remodulin, it's because that therapy as I mentioned in my introductory remarks has it's taken two or three years quite naturally for it to gain confidence among physicians and therapy that has wide efficability throughout the New York Heart Association Class II and New York Heart Association Class III ranges of patient. Now, generally thought at the Class II and Class III patients combined represents probably three-fourths of the marketplace. So, let's just say conservatively 15,000 out of those 25,000 diagnosed patients are class II and class III patients. Right now, we have something like 3,000 patients on Tyvaso, so, there's a lot of headroom, just the opposite situation with Remodulin, there's a lot of headroom for Tyvaso to grow, and the space for Tyvaso to grow is not limited in the same way it is, as Remodulin and hence it's entirely foreseeable as Remodulin's revenues will continue to grow at the single-digit rate, but that will not stop Tyvaso's revenues from growing at a much faster rate. Hence it's predictable that Tyvaso will, in the near term, become the largest source of revenues for United Therapeutics compared to Remodulin. I hope that was responsive to your question.

Operator: Philip Nadeau, Cowen and Company.

Philip Nadeau - Cowen and Company: Martine, in your pipeline update, you didn't mention your neuroblastoma antibody? Could you give us an update on the status of the antibody and how big of a market opportunity you think you could address?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Thanks a lot for the question from Cowen, and we certainly look forward to presenting at your company's event next week, and I'd like to ask Roger, who is managing the neuroblastoma program to kindly respond to your question.

Roger Jeffs, Ph.D. - President and COO: Yeah, thanks for the question Phil. Happy to answer it. So, just again for some background, our antibody C-1418, is a monoclonal antibody that binds to a lipid called GD2 on the surface of neuroblastoma cells, and for those who may know, neuroblastoma is cancer of peripheral nervous system and responsible for about 12% of all deaths due to cancer in children under 15. With about half of the patients with neuroblastoma having what's called a high risk form of the disease with very poor long-term prognosis and survival rate. There was a trial by NCI that showed improved survival. Subsequent to that trial, NCI has also recently completed a 105-patient safety and toxicity study with the antibody. And what we have done is acquired the rights to manufacture and commercialize C-1418 for the market. We are in late-stage process validation work. So we have done, I would say, 95% of the work that we need to do. There's certainly more work to do, but we are in the submission build phase now, both for the U.S. and Europe. And it is our intention to file, based on discussions with both the U.S. and EU regulatory authorities later this year. So that would suggest that this therapy would be approval -- be approved sometime in 2014. So we're very pleased with our -- the capability that our manufacturing team in Silver Spring and their ability to progress the process and the scale up of the antibody production. And we look forward to supporting this new market.

Philip Nadeau - Cowen and Company: Great. Do you owe NCI a royalty?

Roger Jeffs, Ph.D. - President and COO: No, it was a license fee straight out, basically.

Operator: Terence Flynn, Goldman Sachs.

Uya Chuluunbaatar - Goldman Sachs: This (Uya Chuluunbaatar), in for Terence Flynn. Just a question on the ongoing FREEDOM-EV trial have you made any changes to the protocol?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Roger you'd like to answer that question?

Roger Jeffs, Ph.D. - President and COO: Sure, so again for background as Martine alluded to earlier FREEDOM-EV is our long-term time to clinical worsening study of oral treprostinil added to background therapy, to single background therapy, in patients with pulmonary hypertension. They must be nearly diagnosed with a duration of background therapy no shorter than 30 days and no longer than 1 year. So we're going to follow those patients for several years and observe the time to clinical worsening and see the impact of oral treprostinil on top of single-background therapy. That study is enrolling. We plan to complete the study enrollment in 2014, and that would suggest a completion and unbinding of that study in first half of 2016. It's a global study. We have over 125 sites that we are initiating. We're very pleased with the progress that we're making in that front. We have made and, with all protocols over their lifetime, there are amendments that go on. In fact, I think, when we look back to our original FREEDOM-M and FREEDOM-C and C2 studies, we had over five amendments. So we have, similarly here, we have an amendment to the protocol that has tweaking different aspects of the protocol, including some endpoint definition, as well as introducing a different dosing strategy. Again, that's normal for the course of development, and there'll be further amendments, I won't predict now, I actually guarantee, over the next three to four years as we complete this protocol.

Operator: Geoff Meacham, JPMorgan.

Geoffrey Meacham - JPMorgan: So, I guess a follow-up on FREEDOM-EV. Is there a plan to design a formal interim analysis on this study? Do you feel like this could help the ongoing FDA review of oral? Then just a real quick one on Tyvaso. Could you talk about the new TD-100 device, how you think it's different relative to the current one?

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Let me ask Roger, if you don't mind, Roger, to answer both those questions, and then I'll wrap up.

Roger Jeffs, Ph.D. - President and COO: Yes, on the TD-100, so that's the device that has improvements that were somewhat FDA-mandated at the time of approval, so we had a post-marketing commitment to do certain things, like put an alignment key on the dome and the base and other aspects, and we've completed that. So those improvements were done, approved in late 2012, and we're launching that into the market basically the next quarter. So we'll be transitioning our patients to this newer device. I would also say that we're in development of a third-generation device, which we're actually calling the Gen 3 device, which is a further improvement in same mechanical aspects, so it won't require any new studies. But it's a miniaturization of the device, an improvement of the device and an improvement, in particular, in its intelligence, if you will, so that we can look at patient compliance and adherence. The question on FREEDOM-EV, if you could remind me what that was again?

Uya Chuluunbaatar - Goldman Sachs: Yeah. Is there a plan – I know one of your competitors has an interim analysis on their study. I'm wondering if it's possible with the current powering assumptions to design that into FREEDOM-EV and do you think that could help out the ongoing FDA review if there is a more near-term data disclosure?

Roger Jeffs, Ph.D. - President and COO: Yes, so, in terms of an interim, we don't plan to do a study interim analysis. We're enrolling over 850 patients to do it accrue approximately 400 events. The difficulty with an interim by the time that you collect the data to do the interim analysis, you've almost enrolled the complete study population. So become instead of statistical ways to power, so it's not something we are looking to do, but I appreciate that other people are doing it because I think they've also did their sample size further. So, they must be worried about event, right. So, we can involve I think as we go, but currently there is no plan to do that as it relates to the current application as we said we've resubmitted the NDA based on the merits of the original filing and we continue to believe that the merits of that original filing warrant approval. We will know like we would in about five weak times, what the outcome of that discussion is, and then we can based on the outcome we can then figure out how to move forward with FREEDOM-EV either is part of the solution or part of the market expansion.

Martine A. Rothblatt, Ph.D. - Chairman and CEO: Thanks, Roger. Thank you everybody for your question this morning. We're moving around to the half remark after the start of the question period. So, let me wrap up that we appreciate the opportunity to share an annual and quarterly results with you. I'm very pleased to be able to share such great results with you. All three of our products are continue to do very well as we around 2012 and start off in 2013. Remodulin we expect continue growth for Remodulin in the very near-term from international opportunities Japan, China, Europe and in the medium-term from the new implantable pump once that receive label expansion from the FDA that we think has the prospect to as much as double the size of the Remodulin market. We expect continued growth in Tyvaso, in part because we are seeing sings of our greater than ever confidence and interest in physicians, and we are expecting an inflection point with a faster uptake in growth starting this year, and also because of the factors that Roger just walked us through in terms of the second generation and even third generation inhalation devices making that therapy easier and easier to use. Then finally, with regard to Adcirca, we have surpassed all competitive therapies in terms of that being the most prescribed drug for pulmonary hypertension, and instead of this being any kind of a plateau, we actually just see it as a launching pad for yet greater growth and the high likelihood that Adcirca will continue to be the foundational therapy for pulmonary hypertension. We have a really exciting pipeline. Roger talked about the FREEDOM-EV study, and I touched on the TransCon treprostinil. There are other exciting things in our pipeline. We talked about the 1418. We've got some exciting antiviral opportunities in our pipeline and another entire prostacyclin platform based on the beraprost molecule, both in its sustained release and also in its TransCon formulation. So great pipeline, great currently marketed products.
