Thanks, Shirley. Good afternoon, and thanks for joining us on our call today. I'll provide some highlights on the quarter and then briefly discuss the performance of our two operating segments, clear aligners and scanners. John will provide more detail on our financial results and discuss our outlook for the fourth quarter. Following that, I'll come back and summarize a few key points and open up the call to questions. I'm pleased to report third quarter results with revenue and earnings above our outlook, driven by higher-than-expected Invisalign volume, offset somewhat by lower ASPs and foreign exchange. We also had another record quarter for iTero scanner business. Q3 Invisalign volume increased 5.5% sequentially and up 35.3% year-over-year, reflecting strength across regions and customer channels as well as strong growth from both teen and adult patients. From a product perspective, we saw strength across the Invisalign portfolio, with growth from both the comprehensive and non-comprehensive products, reflecting acceleration in the non-comprehensive category related to expansion of our product portfolio, as well as new sales programs and promotions intended to increase adoption and utilization. We also saw continued strength from international regions, especially Asia-Pacific, which is our second largest region after the Americas in Q3. Finally, during Q3, we trained another record 4,930 doctors, driven by APAC and Latin America, including Invisalign Go doctors, which represent continued expansion of our customer base, especially GP dentists. And Invisalign utilization increased overall to 6.1 cases per doctor, including another record for NA orthodontists. Overall, while I'm pleased with the strong volume growth that we achieved this quarter, there were a couple of unexpected factors that impacted our results. In Q3, Invisalign ASPs were down sequentially due to a combination of promotional programs, unfavorable foreign exchange and product mix shift, partially offset by price increases…

Thanks, Joe. Now for our Q3 financial results. Total revenue for the third quarter was $505.3 million, up 3.1% from the prior quarter and up 31.2% from the corresponding quarter a year ago. Year-over-year revenue growth was favorable in all regions. Clear aligner revenue of $421.1 million was down 1.4% sequentially, driven by lower ASPs as a result of higher-than-expected discounts and unfavorable foreign exchange, partially offset by increased volume. Year-over-year clear aligner revenue growth of 25% reflected strong Invisalign shipment growth across all customer channels and geographies, and was partially offset by lower ASPs. As Joe mentioned earlier in his remarks, Q3 Invisalign ASPs were down sequentially and year-over-year due to a combination of promotional programs, unfavorable foreign exchange and product mix, partially offset by price increases across all regions. In Q3, we offered a new product promotions designed to increase adoption of Invisalign treatment and we saw much higher-than-expected uptake on some of these promotions. In addition, at the beginning of the year, we created a more robust North America Advantage customer loyalty program, which has been very favorably received by our doctors. The new Advantage Program changed to a semi-annual discount qualification period instead of a quarterly one, with additional tiers that provide doctors with more incentive to move up the tiers by increasing their Invisalign case volume. As a result, more doctors are moving up in tiers and achieving higher overall discounts than they were under the prior program. In Q3, we also saw a shift toward lower ASP non-comprehensive products, some of which is tied to promotions and some is tied to continued progress expanding our business with GP dentists and DSOs. Specifically, Q3 ASPs were down by approximately $85 and includes $24 of unfavorable foreign exchange, and down $80 year-over-year and includes $15 of…

Thanks, John. Overall, Q3 was another good quarter with strong growth for both the Invisalign and iTero businesses. Our performance reflects continued success in driving adoption and utilization across all region and customer channels, as well as an increased traction in new expansion markets with our DSO partners. We have a huge market opportunity ahead to connect millions of consumers with Invisalign doctors for orthodontic treatment, and whether it's through traditional routes in a doctor's office or through new consumer-friendly approaches like the Invisalign Experience program, we are committed to a doctor in the center of everything we do. Align is the best positioned company to help doctors successfully navigate the rapidly-changing dental market. We're excited to be guiding them through this digital transformation. I look forward to following up with many of you in the coming weeks at various conferences and industry meetings, including the Invisalign Ortho Summit in Las Vegas next month where approximately 2,500 doctors and their staff will spend two days sharing Invisalign and iTero best practices, one of our most important peer-to-peer clinical education events. With that, I'll turn the call over to the operator. Operator?

Our first question comes from the line of Robert Jones from Goldman Sachs. Please proceed with your question. Robert Patrick Jones - Goldman Sachs & Co. LLC: Great. Thanks, Joe and John, for the question. I guess just to start on the lower ASPs, which you guys provided some details around at least the areas that impacted it. And John, if I heard you correctly, it sounds like of the $85 sequential decline, if I remove FX, it would have been more like $60, $61 sequential decline. So, of that decline, I was hoping maybe you could just break down how much of that came from promotions versus mix shift. And then I guess the follow-up would be, I don't necessarily remember you guys talking so much about the additional promotional program. So, curious if there was something in the marketplace that kind of forced you to react to put the promotions in place, or if this was something that was always planned and maybe the uptake was just greater than you thought?

Yeah. Hey, Bob. This is John. On the remaining piece that's left, about half of the drop in ASPs was due to mix. It was mix shift to the lower stage products. And about the other half or $30 or so was related to those promotions.

And Bob, it's Joe. Look, obviously on the Advantage Program and the special programs we ran for the quarter, we do this all the time. We're trying to encourage customer stickiness. We're checking out different segments of the marketplace. We do this all the time. But in this case, what happened is we incentivized the upper end of our customer segment. We did not get the engagement in the lower end that we anticipated. And so, in that sense, we will shut that thing down. We won't repeat it again. We obviously learned from it and we move on. Robert Patrick Jones - Goldman Sachs & Co. LLC: And then I guess, Joe, just to follow-up on that then, as we think about ASPs for 4Q and then more importantly beyond 4Q, is it safe to assume that FX will be what it is but that at least the portion of the headwind from the promotion should normalize?

Yeah, that's correct. Think about it as flat, Bob. Robert Patrick Jones - Goldman Sachs & Co. LLC: Got it. Thanks, guys.

Yes. Thank you.

Our next question comes from the line of Brandon Couillard from Jefferies. Please proceed with your question.

Thanks. Good afternoon. Maybe, John, in terms of the aligner gross margins in the quarter, can you break out the impact of the manufacturing capacity expansions relative to ASPs? And as you look into 2019, given we're kind of bouncing along the low end of your three- to five-year model here at about 73%, would it be logical to expect year-over-year expansion in terms of the aligner margins as you start to soak up some of that new manufacturing capacity expansions?

Yeah. You're right, Brandon. I mean, what we'll see initially because of the low volumes, we'll see more of that fixed cost over that low volume. So, that's a 0.5 to 1 point impact due to the manufacturing start-up. And then as we get more efficient, we should see some improvement as we go forward related to those manufacturing costs.

Thanks. And then one for Joe. The OpEx guidance for the fourth quarter implies the slowest year-over-year growth rate in a few years now. To what extent are you beginning to see perhaps some diminishing returns from incremental investments, be it feet on the Street or marketing or otherwise, perhaps in some of the more international and emerging markets?

Brandon, I think if you look at our growth, I mean our growth is above 30% right now. So we don't see any diminishing returns in that sense. Remember, we had a big third quarter when you look at our volume growth versus other years. So the normal sequential kind of iteration that we go through between third and fourth quarters, we don't really believe it's going to be as dramatic as it has been in the past. And so this doesn't reflect anything from a market standpoint. Remember, as you look at our performance overall, international market's performed extremely well, okay? We still had incredible shipments in North America from an Invisalign standpoint. We also had great iTero, too. So, primarily what we're looking at is what we have with these promotions in the sense of the ASPs driven by them and the corrections we have to make as we go into the fourth quarter.

All right. Thank you.

All right, Brandon.

Our next question comes from the line of Jon Block from Stifel. Please proceed with your question. Jonathan David Block - Stifel, Nicolaus & Co., Inc.: Great. Thanks, guys. Good afternoon.

Hey, Jon. Jonathan David Block - Stifel, Nicolaus & Co., Inc.: Hey, Joe. First one, John, I think you mentioned flat scanner revs Q-over-Q and I've got to make some other assumptions. But I'm backing into around a $1,200 Invisalign ASP for 4Q 2018 based on your volume guidance. 3Q 2018 I believe was $1,230 on a worldwide basis. You mentioned some of the promotions that were run in 3Q will not be repeated. So why the continued decline on the worldwide ASP into 4Q? And then do we think about extrapolating that $1,200 if I'm right out to 2019? And then I've got a follow-up.

Yeah, Jon, I would look at Q4 as continued mix effects that we have. So, as we are – the low stage that we've seen through Q3, some of the mix shift that's happening, that will continue into Q4. But like we had said, those promotions that we had, those specific promotions that were driving down some of the ASPs in Q3 will not continue into Q4. . Jonathan David Block - Stifel, Nicolaus & Co., Inc.: Okay. And then, Joe, you may have answered this to Robert's question earlier, so I apologize if this is redundant. But I think it's important obviously with the focus on the promotion. So, can you be a little bit more clear that the promotions that you ran in the quarter, you hear the word promotions at the same time that two or three comprehensive clear aligners were introduced in the market for the first time ever and that's going to freak a lot of people out, right? So the promotions that you mentioned, were those specific to express-type cases? Were they more specific to comprehensive? Any clarity you can give would be great. Thanks, guys.

Yeah. Jon, to answer your question backwards is, these are comprehensive cases. From a competitive standpoint, look, we continue to monitor the competition in the marketplace. Ormco is still out in ANZ and not completely engaged. 3M has obviously hit the marketplace in the United States and we see it. But these promotions were not geared toward trying to stop any competition that we're feeling right now. That wasn't the whole part of this promotional piece. Remember, third quarter's a big teen season. We had to make sure that we run the proper promotions going in there. This is a teen promotion and also an adult promotion too. Again, we're just trying some things in the sense of incentivizing the marketplace and it just happened to engage the upper tier of our Advantage Program rather than a lower tier that we had hoped. And these go on all the time kind of under the radar screen, Jon, and we don't talk about them. This one in the sense of how it performed obviously affecting ASP, we just have to give you clarity on it. But, again, I want to re-emphasize, this is not based on anything competitively that we saw in the marketplace that we thought we had to move around. Jonathan David Block - Stifel, Nicolaus & Co., Inc.: Very helpful. Thanks, guys.

Our next question comes from the line of Elizabeth Anderson from Evercore ISI. Please proceed with your question.

Hi. Yeah. Thanks for the question. Speaking of what you were just talking about on sort of engagement in the lower end of the market, how are you sort of thinking about what you're going to shift going forward? That would be my first question. And then could you sort of also talk about the typical GP path in that lower-end customer? Do they start with lower-priced products and then sort of move up, or do they sort of stay in that lower-level product mix shift? Any further color on that would be really helpful. Thanks.

Thanks. Actually can you repeat the first question? You're kind of light on the volume. We couldn't hear the first part of your question.

Oh, sorry about that. Is that better?

Yeah.

Yeah.

The first part of my question was, obviously, you said that you didn't get the engagement you were hoping for on the lower end of the market. And so I was just wondering sort of what you've learned from that and sort of how you're thinking about that engagement with that segment of the market going forward.

Yeah. On the lower end of the marketplace, it's just exactly how we target those incentives and how broad do we make them, okay? This was broad across all of our Advantage tiers. In the future, we'll just have to focus on the lower tiers in that sense in order to encourage that piece. I mean, it's that simple kind of feedback. We thought it'd be more of a balanced response across the tiers and it wasn't. And now on the GP, I think your second question had to do with GP doctors and how they get engaged. With iGo, as we start iGo, it's a mid-range product that we position with GPs that allow them to be able to do certain kinds of movements that we think are relatively simple to learn and for doctors to really start off the product line. And so, as you see the iGo growth all around the world, that's predominantly what we'd call a mid-range product that we're positioning with GPs at the moment.

Okay. Thank you.

Does that help?

Yeah. That was helpful.

Yeah. You're welcome.

And Elizabeth, I'm just going to add one other thing just in terms of what we're talking about with respect to ASP. The other part of the conversation has to do around the new Advantage Program this year and how that has additional tiers, and intended obviously to incentivize doctors to move up in tiers, and what we saw was the higher volume doctors moving up in tiers more than the lower tiers. So, that's part of the impact as well.

Our next question comes from...

Question...

Sorry?

Go ahead, Jeremy.

Our next question comes from the line of Steve Beuchaw from Morgan Stanley. Please proceed with your question.

Hey, Steve. Steve Beuchaw - Morgan Stanley & Co. LLC: Hi, and thanks for the time here. I wonder if I could come back, Joe, to a point that you made earlier, maybe an intersection of a couple points. I mean, you talked about how doctors are thinking about an evolving environment. I wonder is there something in the environment that is changing the way that clinicians respond to promotions or product line efforts or to the Advantage Program? Is there something different about it this time? I ask the question because historically the company has a lot of experience running these types of programs.

Yeah. Steve, I don't think the market is conditioned any differently than it's been before. The biggest change we've seen in the market is really just SDC in the United States marketplace. But that is a completely different segment since it's not through doctor's offices, and obviously that's not where the competition is right now. I think if you look at this, Steve, I think with this new Advantage Program we launched in North America in 2018, it just has a different series of brackets, a different series of rewards, at different kind of bonus levels. We haven't really engaged promotions around those things before. So it was a little bit of a learning curve in the sense of how those brackets, as Shirley talked about yesterday actually respond to these kinds of promotions. Don't look at this – I think I can understand your questions and the previous questions about, is there some external aspect that's really driving those things. If there was an external some kind of catalyst in this sense, we'd tell you. I'd tell you, okay? That's not why we do these things. We do these things to encourage customer stickiness. We do these things to figure out what really works in the marketplace. Look, I've never been in a business that has price elasticity curves like this business. And you really have to study those. We launch promotions, we do them at certain prices. We see what the uptakes are and we learn from those things. We're just launching this against a different type of an Advantage structured program and these tiers are different and this take-up was completely different than what we've seen before. Steve Beuchaw - Morgan Stanley & Co. LLC: Okay. Got it. And then just to follow-up on your point about SDC, I think I know the answer to this, but your view is still that any overlap between SDC cases and Align cases is low-single-digit percentage-wise, is that still correct?

I think we've always said it's about – back when we were actually comparing data with these guys, back before our lawsuit, and it was about a 10% overlap is what we saw overall. We don't have any information that would change that at all at this point, Steve. Steve Beuchaw - Morgan Stanley & Co. LLC: Okay. Perfect. Thank you very much.

Our next question comes from the line of John Kreger from William Blair. Please proceed with your question. John C. Kreger - William Blair & Co. LLC: Hey. Thanks very much. Joe, any update on the timing for mandibular advancement in the U.S. or the palate expansion product that you talked about at Investor Day?

Yeah. Hey, John. We're expecting in the fourth quarter is what we said all along. Our communications with the FDA have been nothing bad or anything that would suggest that we're not on course. So I'd just say we're still sticking to our plan of being able to launch this product in the fourth quarter United States. John C. Kreger - William Blair & Co. LLC: Okay. And then how about the palate expander product?

Palate expander, we're still working through that. When you think about it, our Invisalign First product is a palate expansion product but it's not a rapid palate expansion product. So we're digging into that six- to eight-year, nine year marketplace with Invisalign First. We're still working through – in fact, I went through it this morning with a team. We're still working through the rapid palate expander and we'll give you an update on that as there's more to talk about. We're still thinking it's trialing in 2019 like we indicated at the most recent investors' conference. John C. Kreger - William Blair & Co. LLC: Okay. Thanks. And then maybe just, John, any kind of key puts or takes you want to call out as we start thinking more about the outlook for 2019? I assume FX will be a bigger factor in the coming year?

Yeah. We're not giving the 2019 guidance, as you know, John. But FX is a piece of it. We call it out. It is what it is. And then everything else is on our operational performance. But we'll give a good update on 2019 at the next call. John C. Kreger - William Blair & Co. LLC: Great. Thank you.

Yeah. You're welcome, John.

Our next question comes from the line of Matthew O'Brien from Piper Jaffray. Please go ahead. Matthew O'Brien - Piper Jaffray & Co.: Afternoon. Thanks for taking the questions. So, if I look at your slides that you provided, slide 30 specifically, you can see a step-down Q3 to Q4 on the pricing side both worldwide and internationally. Were you running some kind of program similar to this back then? And then we saw recovery over the next several quarters. Is that something kind of like what we should expect this time around?

Yeah. I mean, what we see, Matt, that comes through some of those slides and trends is FX effect. So, if there's foreign exchange that comes through there, it shows up as well. So, some of that, especially when you look on the international side, you can see some of the FX effects there. Matthew O'Brien - Piper Jaffray & Co.: Sure. Just to punch a little bit further on that question specifically though, the moderation that you should get from the promotion going away, maybe some more mix benefits going forward. This should be kind of the low watermark maybe here in Q3 for the ASPs with the gradual increase over the next several quarters. Is that fair?

Yeah. I think what we're expecting is kind of the Q4 ASPs that we're kind of calling should be that low point and that's how you should think about things going forward. Matthew O'Brien - Piper Jaffray & Co.: Okay. And then as the follow-up question and actually to talk about something positive in the quarter, even though there was a lot positive. On the scanner side specifically, can you parse out a little bit where that performance came from? Because that should be a pretty good leading indicator for the business going forward. DSOs, international, et cetera, would you mind just providing a little more color there?

Yeah. Matt, it's Joe. When you look at it, every region we had a lot of strength in iTero. You start with we have now major penetration into China and great uptake there. Last year, we were approved in Japan and that's been good too. So, really all up and down Asia it's been strong. In North America, it's been strong across our individual doctor base but also, as you mentioned, the DSOs have been very strong also. And then also in the quarter, we did see increasing momentum with iTero scanners over in Europe too, which is our most difficult competitive market. We have good momentum there too. The launch of the Flex product line and iTero 2 were really great launches. Customers loved the product too so the response has been terrific. So, everything has been working extremely well with that business. But remember, that's just a wonderful footprint for us for future Invisalign business once we have those scanners in place. Matthew O'Brien - Piper Jaffray & Co.: Got it. Thank you.

All right, Matt. Thank you.

Our next question comes from the line of Richard Newitter from Leerink Partners. Please go ahead.

Hi. Thanks. I wanted to just clarify. I think you had said you're still expecting mandibular expansion – I'm sorry, the mandibular product in the fourth quarter, best of your ability to predict the FDA. Is it right that that's not factored into your Invisalign case volume guidance or your 4Q guidance?

Yeah. We don't factor it in, but honestly within one quarter of the launch of that, we wouldn't expect anything material, Richard, to report in that sense. And that's not anything to do with mandibular advancement. It's just the way things work around here in the sense of doctors will try this, they'll do a few cases, they'll get used to it. And then, as we move into 2019, we'll give you some idea of what we think mandibular advancement United States uptake would be.

Okay. That's helpful. And just maybe one other one. I noticed that the percentage of cases submitted with a digital scanner in the Americas was flat and it's been increasing almost every quarter for quite some time. I'm just wondering if that's somehow linked to some of the kind of anomalies that we saw around trends with ASPs or if there's any other explanation there?

No, Richard, there's no correlation with the ASP side. Remember, last year, we ceased allowing 3Shape to be able to submit scans. And so those doctors would have to go back to PVS impressions, and we think that's pretty much what drove that. Obviously, our scanner sales have been really strong in United States. So we think that's just basically a re-submittal because of the situation we have with 3Shape right now.

Okay. Thanks a lot. And then maybe just one last one. You said that you didn't get an expected kind of reaction in the marketplace from kind of the promotions across kind of both parts of the market, complex and simple. I guess what's your hypothesis as to why it didn't work on the low end of the market? Or do you have kind of a running assumption as to what maybe you got wrong or why it didn't work?

Yeah. I think, Richard, first of all, it's not low end, it's low tier. So we have an Advantage Program. An Advantage Program has several tiers. It starts at Bronze, it goes all the way up to Double Diamond, okay? And so, when we talk about that, these are still broadly their comprehensive cases, okay? When you put these promotions in place, you want to make sure you're sensitive in the sense of who you're incentivizing across these brackets, right? What we're saying is we didn't have strong enough incentives on what we'd say the lower end of our Advantage tier program. And, obviously, that'd be the change we'd make going forward. Makes sense, Richard?

Yeah. Thanks.

I thought we lost you.

All right. Our next question comes from the line of Erin Wright from Credit Suisse. Please proceed with your question.

Great. Thanks. I won't ask about ASPs, but the Invisalign Experience locations, could you provide any sort of new metrics around in terms of conversion rate or traction or any sort of key performance kind of metrics there. And how will the economics work for the doctor-led Invisalign Experience locations with the rebranding and all? Thanks.

Erin we haven't given any statistics yet on our Experience centers. And we only had four stores, and now we're expanding the other eight stores right now. As we move into 2019, we'll be more transparent with that information. The doctors can engage in several ways. The doctors are actually engaged with the store. These products have a certain premium assigned to them, because we actually attract the patients and send the scans to the doctors or whatever. So, depending on what it is, Signature, Signature Plus or Deluxe, there's obviously a lab fee for the aligners but there's also a certain fee for those types of products. And then we're talking about the halo effect too. The halo effect, sometimes it's the doctors who aren't even associated with the program at all, we're still seeing a significant increase in Invisalign sales to those doctors just because of just the raising the awareness of Invisalign and doctors in that specific geographical area. And those are areas of anywhere between 10, 25, up to 50 miles we start to see that kind of response.

Okay. Great. And then you've previously alluded to financing initiatives for customers that seems to make sense here, but I don't really hear you speak much about it. I guess where does that stand today on that effort? And that remains purely a third-party relationship today? Thanks.

Hi, Erin. Yeah. This is John. Yeah, the financing, it continues. It's primarily in the U.S. and it's something where it's financing that's not on our balance sheet's third-party company that we work with. And really we're just trying to find easier ways for our end consumers to be able to use Invisalign and make things easier for them. So we continue to do it. It's part of the conversion that we try to use. And it's been rolled out across the U.S. for a few quarters now.

Okay. Great. Thank you.

Welcome.

Our next question comes from the line of Steven Valiquette from Barclays. Please proceed with your question.

Thanks. Good afternoon. So I guess for the 35% case growth in the quarter, which obviously accelerated pretty nicely. I'm just curious if there's any color on how much of that volume growth was maybe tied to what we'll call the overly enhanced promotional activity. Or are you more of the mindset that maybe you would have had essentially the same case volume growth overall if there were no alterations to the loyalty program? Thanks.

Yeah. Steve, we can't nail it exactly, but we can tell you it's 1% to 2% on the North America volume.

Okay. One other quick one – again, if you're slightly off on where you want to be on your ASPs because of this activity, just kind of thinking out loud without giving anything away for next year, just curious if you also think you could potentially increase list prices maybe a bit more than normal to get you where you want to be on ASPs for 2019, just as another lever that you could pull if you wanted to when thinking about optimizing price.

Well, you don't want to comment on price going into a year. We never do that, Steve. But we have raised price every year in the last three years. Obviously we raised price in this quarter, too. And it's been part of our strategy. It fuels a lot of the things we would do. We talk about Invisalign Experience and our marketing campaign and driving customers' adopters, also all the technology we invest into. So it's been a pretty large part of our strategic plan. But I don't want to comment on 2019 in that sense.

Okay. All right. Got it. Thanks.

Our next question comes from the line of Jeff Johnson from Robert Baird and Company. Please proceed with your question. Jeff D. Johnson - Robert W. Baird & Co., Inc.: Thank you. Good evening, guys.

Hey, Jeff. Jeff D. Johnson - Robert W. Baird & Co., Inc.: Hey, Joe. So let me start just on the Invisalign Experience. It sounds like you're moving that into some private practitioners or some other offices here in the fourth quarter. Any discussions on moving that into the DSO channel where you could almost supercharge that or really get into 600, 800 offices at a time? And in those cases, I think you alluded to it, Joe, a little bit in your comments just a second ago. But my sense, at least from the conversations I've had is that the gross margins are actually accretive in cases that come through that kind of channel because you're kind of doing some of the work to get the patient into that office. Is that a fair way to look at that?

Yeah. Jeff, it's a really fair way to look at it. I mean, we talked about Aspen last quarter. I mean, the whole idea of the Aspen piece and their uptake of iTero scanners was to put what we used to call a store in store. We now call it an Invisalign Experience thing in the doctors' offices within Aspen. And part of what we've done in the stores is we've created obviously consumer material. We've created a lot of things. From a customer engagement standpoint, turning customers into patients, we put those in place and we'll be able to employ in those DSO stores too. So, that's been a big part of our strategy and it's one of the reasons you see such a big uptake in the DSOs that we've been selling to and reporting. Jeff D. Johnson - Robert W. Baird & Co., Inc.: Yeah. Fair enough. And then, again, there hasn't been enough ASP questions here tonight but I just want to understand, John, your comments. You get some of the promotional activities right-sized in the fourth quarter. Currency probably is a little bit bigger of an impact going forward. So, fourth quarter you would expect ASP to be down sequentially a bit versus 3Q, is that right? And then we kind of see a recovery throughout 2019 or at least a little bit trending up in 2019, as some of those currency headwinds in the back half come off and maybe some of the promotional activity headwinds do as well?

Jeff, what we would see is – you're right, on the FX, you see it come down a little bit from an ASP standpoint in the fourth quarter. But then from the fourth quarter, we expect it to be about flat, just given the mix and other things that we've talked about in terms of what we see in the business. Jeff D. Johnson - Robert W. Baird & Co., Inc.: Okay. And just to clarify that, so whatever our fourth quarter ASP, wherever that ends up, that you would expect holding flat, then moving throughout 2019 sequentially?

Yes. That's how we would look at it. Jeff D. Johnson - Robert W. Baird & Co., Inc.: All right. Thanks, guys.

Yeah. Thanks, Jeff.

Our next question comes from the line of Ravi Misra form Berenberg Capital Markets. Please proceed with your question.

Hi. Thank you for taking the question. Just a couple based on the margin outlook for the business. So, just working through that flat pricing outlook, how do we think about the gross margin implication on the aligner business. I mean, you have these plants coming online. Is it similar type of kind of ramp that we look at a step-down from 3Q in the aligner gross model and that kind of remains flat or slightly increases going forward into 2019? And then, just a question on the marketing strategy, as kind of Raph steps aside, you have a number of new programs going on here. You have a new marketing leader coming in. You have an orthodontic summit in a month. How do you kind of like look at your dental segment and your customer base, the orthodontists here? Are we in a world where you're trying to get greater productivity from your top dentists and let the less productive guys I guess to call it less of a focus on that? Or is there room for everyone here? How are you looking to approach that? Thank you.

Ravi, I'll take the gross margin question. Yeah, as we said, coming online with some of the manufacturing, it's at certain amount of costs that we need some of the volume now to be able to spread those costs over. So we guided in Q4 to reflect that. And then, as we get more efficient related to that manufacturing, both the manufacturing and the treatment planning that we have kind of globally, we'll start to see some of the efficiencies related to that manufacturing and treatment planning that will affect our gross margins.

And Ravi, it's Joe. Your question on the segment and top dentists versus – or top orthos versus lower brackets, I'd just end it by saying there's room for everyone. You have to segment this market always between general dentistry as we call GPs and also orthodontists. But when we talked about at Investors Day, we see a market that we used to measure as 12 million case starts a year as potentially 300 million. But what we specifically talk about with our doctors, particularly on the ortho side, is this is a massive what we call analog to digital conversion, right? If you really want to get the productivity of a digital-based orthodontic system that ends up in plastic, and that's what our process is, is you really have to do predominantly a majority of your business has to be in digital. And those doctors that walk forward that want to go through that journey with us, we have a number of programs to take them through from financing to how you encourage more consumers, how you set up your practice, all those things, so you can make it as efficient as possible. On the general dentistry side, we often work from a restorative standpoint to make sure that we can work within those restorative workflows and make sure that it's profitable for those docs and they understand how to use these things. Ravi, one thing I want to make certain, and maybe it's just me being overly sensitive. Don't take Raph's announcement in any way as any indication that he had some responsibility for this promotional aspect for what went on. Raph's been tremendous for us. After running our international business, coming in and running marketing and strategic development and also business development, he's been critical to this business. This is not some kind of smoke and mirrors. This is Raph making the decision from a family standpoint that he's had issues with that he has to deal with right now. We support Raph in that from a family standpoint. This has nothing to do with him.

Thanks. Next question, please.

Our next question comes from the line of Michael Ryskin from Bank of America Merrill Lynch.

Hey, guys. Thanks for squeezing me in. A lot of questions have been taken but I just want to follow-up on a couple points. One is, are you getting any sense that the pretty substantial price difference in the quarter, the discounts, are they being passed onto customers by the dentists? I know it's tough to measure those channels sometimes and it's aggregated, but are you getting any sense that the dentists themselves are being squeezed on pricing by the end customer and they have to do something to adjust?

We don't have any data, Michael, to hold up with that. I'd say, remember there's a million points of light in this business too because there's so many doctors overall involved. But I don't feel this has to do with having these promotions actually in some way and have that passed onto consumers. It's just not the feedback we get or what we think is going on.

All right. And then a follow-up just real quick on the DSOs. I think you mentioned 40% growth in the quarter as a customer grouping. And the mix is shifting, still a small part of the overall business, but is there anything that's different there in terms of how much price you're able to get with those customers versus some of the stand-alone docs?

From a DSO standpoint, obviously these are large contracts we put in place. And there's significant price discounts in the sense for the volumes that the DSOs offer. So, when we talk about mix, there's a certain amount of mix associated with DSOs. When you see these kind of growth rates, 40%, it's obviously some aspect of the mix that we're talking about. So, when you think about that too, Michael, is that we don't have to spend as much OpEx on the DSOs. And it's really important to understand. A lot of them since they're general dentists, they use their own patients to generate their demand. The normal GP dentists would have 1,500 to 2,000 patients per office. We could help them mine those patients to understand which ones would want orthodontic treatment or could stand for orthodontic treatment or not. We don't have to have the amount of sales coverage that we'd have with individual doctors. So you're going to have a lower overall ASP on those businesses, but we feel that from an OpEx standpoint we're not spending as much money too. So, from a gross margin standpoint, it's still positive for us.

All right. Thanks.

Yes. You're welcome.

Our next question comes from the line of Chris Cooley from Stephens. Please proceed with your question.

Good evening, and thanks for letting me just hop in here at the end. Just two quick ones for me. Maybe, Joe, to start with, you mentioned in one of the prior questions price elasticity curves for the market. Could you maybe just give us your views, as the market continues to evolve, what level of margin you think that your higher echelon volume providers expect to maintain and maybe how that differs versus the lower tier provider as these markets evolve, just in terms of profitability by caseload? And then, just from a clarification standpoint, John, if I'm doing the math right, just kind of doing the puts and takes on the one-timers there on the tax rate in the quarter, am I right in that it's about $0.05 to the positive when we look at the net effect there for the 3Q? Thanks.

Yeah, just on the tax, we just gave kind of the highlights of the overall that affected tax. We had guided 21% and ended up at 19.5%. So you can pretty much say that it's 1.5% of our tax was a few things that came in a little bit favorable compared to what we guide. But those two were just kind of the big puts and takes for the quarter.

Understood. Thanks.

As far as the price elasticity curves by docs going forward or whatever, I don't have any comments on that or really any projections of what that's going to be. When we talk about those things, we talk about segments. It would be lower segments or comprehensive segments or teen segments and those kinds of things. But we don't necessarily have that data by doctor or doctor tiers and where it's going to. And if we did have them, not so sure we'd share that anyhow. We just like to keep it at high level. But I'll just tell you that we're aware of these price elasticity curves from a specific – not just demographic, but a specific area of the marketplace all over the world. And we'd have to do promotions and things to test those. And obviously, we respond to those either favorably or not depending on what signals we get. It's an important part of why we do these programs.

That's helpful. Thank you.

Thanks, Chris. Well, thank you, everyone. That concludes our conference call today. If you have any further questions, please contact Investor Relations. And we look forward to seeing you at the upcoming conferences and at the Invisalign Ortho Summit next month. Have a great day.

This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
