Good morning and welcome to the Owens Corning Q4 and Full Year 2015 Earnings Conference Call. All participants will be in listen-only mode. [Operator Instructions] Please note this event is being recorded. I would now like to turn the conference over to Thierry Denis. Please go ahead.

Thank you, Kate, and good morning, everyone. Thank you for taking the time to join us for today's conference call in review of our business results for the fourth quarter and full year 2015. Joining us today are Mike Thaman, Owens Corning's Chairman and CEO; and Michael McMurray, Chief Financial Officer. Following our presentation this morning, we will open this one-hour call to your questions. Please limit yourself to one question and one follow-up. Earlier this morning, we issued a news release and filed a 10-Q that detailed our financial results for the fourth quarter and full year. For the purposes of our discussion today, we've prepared presentation slides that summarize our performance and results for the fourth quarter and full year 2015, and we will refer to these slides during this call. You can access the earnings press release from 10-K and a presentation slides at our website, owenscorning.com. Refer to the Investor's link under the corporate section of our homepage. A transcript and recording of this call and the supporting slides will be available on our website for future reference. Please reference Slide 2 before we begin, where we offer a couple of reminders. First, today's remarks will include forward-looking statements based on our current forecasts and estimates of future events. These statements are subject to risks, uncertainties, and other factors that could cause our actual results to differ materially. We undertake no obligation to update these statements beyond what is required under applicable securities laws. Please refer to the cautionary statements and the risk factors identified in our SEC filings for a more detailed explanation of the inherent risks and uncertainties affecting such forward-looking statements. Second, this presentation and today's prepared remarks contain non-GAAP financial measures. Reconciliations of non-GAAP to GAAP measures may be found within the financial tables of our earnings release and in the appendix of this presentation on owenscorning.com. Adjusted EBIT is our primary measure of period-over-period comparisons, and we believe it is a meaningful measure for investors to compare our results from period-to-period. Consistent with our historical practice, we have excluded non-recurring items, and items that we believe are not representative of our ongoing operations when calculating adjusted EBIT. We adjust our effective tax rate to remove the effect of quarter-to-quarter fluctuations, which have the potential to be significant in arriving at adjusted earnings and adjusted earnings per share. For the full year, our adjusted effective tax rate was 33%. We also use free cash flow and free cash flow conversion of adjusted earnings as measures helpful to investors to evaluate the company’s ability to use cash to pursue opportunities that enhance shareholder value. For those of you following along with our slide presentation, we will begin on Slide 4. And now, opening remarks from our Chairman and CEO, Mike Thaman, who will be followed by CFO Michael McMurray. Mike will then provide comments on our outlook prior to the Q&A session. Mike?

Thank you, Thierry. Good morning, everyone. We appreciate you joining us today to discuss our fourth-quarter and full-year 2015 results. Fourth-quarter revenue was $1.3 billion compared with $1.26 billion one year ago. Adjusted EBIT for the quarter was $136 million, up from $107 million in 2014; adjusted earnings for the quarter were $79 million, up from $55 million in the prior year. For full-year 2015, Owens Corning consolidated revenue was $5.4 billion, up slightly from $5.3 billion the prior year. Full-year adjusted EBIT was $550 million up significantly from $412 million in 2014. Full-year adjusted earnings were up 46%, with $304 million in 2015, up from $208 million in the prior year. Owens Corning also generated nearly $350 million of free cash flow and exceeded 110% conversion of adjusted earnings. Owens Corning delivered an outstanding year. The company is at its best when all of its businesses make meaningful contributions to our financial results. All three businesses posted significant earnings growth for the year and the company achieved record earnings growth. Now as I do every quarter I will review our performance as it relates to the expectations we set for the year. As is the case each year we said that we would continue to make progress toward our goal of creating an injury free work place. Owens Corning continued to maintain a very high level of safety performance in 2015 with 7% fewer injuries than 2014. The company had 85% fewer injuries than the average manufacturing company as measured against the rate published by the U.S. Department of Labor. We remain focused on our goal of zero injuries. In Insulation, we said the business should continue to benefit from growth in U.S. residential new construction, improved pricing, and operating leverage. During the third quarter call, we said we…

Thank you Mike and good morning everyone. As Mike mentioned earlier, Owens Corning delivered an outstanding year, achieving record earnings growth, driven by strong commercial and operational execution in all three of our businesses. I am also pleased to report that we made significant progress in free cash flow this year as a result of improved earnings and strong working capital performance. Now, let’s start on Slide 5, which summarizes our key financial data for the fourth quarter. You will find more detailed financial information in the tables of today’s news release and the Form 10-K. Today we reported fourth quarter 2015 net sales of $1.3 billion, up 3% as compared to sales reported for the same period in 2014. Net sales in our Insulation business increased 6%, primarily on increased sales volumes. In our Composites business, higher sales volumes and higher selling prices were offset by roughly $42 million of foreign currency translation. In our Roofing business, net sales were up 8% primarily on higher sales volumes. Adjusted EBIT for the fourth quarter of 2015 was $136 million, up $29 million compared to $107 million in 2014. Adjusted earnings for the fourth quarter of 2015 were $79 million, or $0.66 per diluted share compared to $55 million, or $0.47 per diluted share in 2014. For the full year, the Company delivered double-digit operating margins. Our 2015 effective tax rate was 33%, in line with our previous guidance. Depreciation and amortization expense for the quarter was $76 million, relatively flat compared to $75 million in the fourth quarter of 2014. Full year depreciation and amortization expense was $300 million and capital additions for the year were $403 million, excluding alloy. In 2015, the Company improved cash from operations by almost $300 million as a result of improved earnings, better working…

Thank you, Michael. As I noted at the outset of today’s call, Owens Corning achieved record earnings growth, driven by strong commercial and operational execution in each of our three businesses. Insulation, Composites, and Roofing all showed strong year-on-year improvement in 2015 and contributed materially to our performance. We’re confident as we enter 2016. With all three businesses performing well, continued growth in U.S. housing and global industrial production growth, we will see another strong year for Owens Corning. With that, I will turn the call over the Thierry to lead us in the question and answer session. Thierry?

Thank you, Mike. Kate, we are now ready to begin the Q&A session.

[Operator Instructions] The first question comes from Stephen Kim of Barclays. Please go ahead.

Well, thanks very much, guys. Congratulations. Great result.

Thank you, Stephen.

If we - lots of questions we could ask. But let's just start with Roofing. One of the things we've heard from people, there's been a little bit of confusion because you don't actually give an actual blended price or anything like that. But your performance in pricing, shingle pricing, appears like it was pretty much in line with our expectations, flat sequentially, but down 5% to 6%, just by way of the fact that Q4 2014, had a more elevated price level. By our math, though, by the time you get into 1Q, the decline in pricing or the headwind from pricing year-over-year should drop into the very low single-digits and really not be that much of an effect. So your comment about having pricing, or I guess, having raw material benefit flow into your margins, would seem to suggest, would seem to dovetail pretty well with what we're looking for. But I didn't hear you give an actual number for raw mats. So I guess maybe if you could help us? If the asphalt and oil prices remain where they are now, what would your expectation be ballpark for the benefit that you would get on raw mat from the lower asphalt costs?

Sure, thanks Stephen. I think we laid out some pretty useful information for our investors in our Investor Day back in November. And went through some of the relationships that we see between oil and asphalt cost, and then also how long it takes the oil cost to come through our economics by 90 days to get to the refinery, about 90 days to get through our cost of goods. As a result of that I think we said a number of times last year, we didn’t really see much deflation in 2015 until really the middle of the second quarter. So we have one benefit in 2016, which we really expect to see really pretty good comps in the first quarter and half of the year on asphalt cost deflation as we carry what was effectively the big drop from a $100 a barrel to kind of $50 to $60 a barrel. We haven't seen that yet in the first part of the 2015 numbers. We would expect to see that in the first part of 2016 numbers. We then have a second effect, which we saw kind of in the second half of '15 where oil then moved further down off of kind to $50 to $60 range and where we see it now. Those affects would start to probably come through our numbers a little later in the first half of the year as they work their way through. So I think it's reasonable to conclude that we are looking at asphalt deflation that could be sizable and not just similar to what we saw last year. I think it's hard to quantify that given the amount of volatility we've seen in oil that the second half of the year is still yet to be seen in terms of what we would buy now and when it would come through our economics, but we're pretty optimistic that on the cost side, we should have a good profile in Roofing and then the real issue is obviously going to be in terms of price and volume, how much of that comes through in terms of our volumes and how much of that we can get the margin in terms of margin appreciation.

Got it. Certainly that would suggest if you did what you did last year, raw material benefit, it actually sounds like it could be better than that and your price headwind is only a couple percent, sounds like it would be very good for your margins. There are a lot of things we could ask about, but let's talk about the Composites business. We know that you have - I think it's about half of your business there is on fixed contracts. Most of those, I would think, are - well, they are, at this point I guess locked in for much of the first three quarters of the year of 2016. And you've given guidance for 20% - $20 million EBIT or better improvement in 2016. This is the segment that people have a lot of concerns about given the Chinese export threat. So I guess the real question that I have for you is how much of your $20 million improved guidance for the Composites segment is largely a function of the pricing dynamic that you have very high confidence in giving what you've already contracted for? And what kind of assumptions are you making about an evolution of a potential export threat from China?

Thanks, Stephen, it’s Michael. How are you? So a couple of things, you're right. So there is about 50% of our volumes that are up for annual negotiation. Those negotiations take place in the fourth quarter and broadly conclude in the first quarter. As you would have seen in our press release and also in my prepared remarks and Mike's prepared remarks is that we expect at least $20 million of improvement primarily coming from both growth and pricing and growth and volumes. I can't tell you that we are largely through our negotiations that take place on an annual basis and we make good progress, so in line with our expectation.

The next question is from Mike Wood of Macquarie. Please go ahead.

Hi, good morning. Just to follow up on that asphalt deflation. In your prepared remarks, you had mentioned that you'll benefit from a portion of the asphalt deflation. Just wondering in your mind what determines how much of the asphalt benefit you'll be able to hold in terms of pricing or potentially have to give back?

I think we've said this over and over again, as we worked our way through kind of the Roofing business over the last three years or four year. It's a very competitive market and we see regional dimensions, product line dimensions, channel dimensions to the competition. So the nature of the Roofing business is very much kind of a day-to-day transaction by transaction type pricing environment. It has been relatively stable over the course of the last year. We think that's a positive for us as a manufacturer. We also think it's probably a positive to most of our channel partners as they have better visibility to their cost of goods, better visibility to their inventory cost which allows them to distribute or retail the product at good margin. So we think the way the market played out in 2015 with relatively stable pricing through the year and with us being able to get a little bit of margin improvement from asphalt cost deflation was a very good outcome for us in '15. And got margins back to kind of that mid teens level, which is where we have historically guided the business. As a matter of fact, we guided the business kind of to mid teens of better operating margins. I think our hope as we look at 2016 would be that we continue to have a good demand environment and we were happy with the way that we've finished that really the entire Roofing shipments and Roofing market ramps through the finish line and didn't die off on the fourth quarter, but had a good finish to the year. We've seen a relatively good start to this year, so we're expecting that demand in sell-through out there is reasonably good and there is good Roofing activity, which typically supports little bit more stable pricing and as a result if that’s the environment we're in, it will look a lot like 2015 and then the asphalt cost deflation would help us a bit more in getting our margins back to something that will be above mid teens.

Great. And the Composite volumes, that growth has really been holding in. I would hope if you can give us some color on what segments are leading that growth? Potentially what end markets are offsetting any of the strong growth that you're seeing?

Thanks. I'd say all regions are seeing growth and so for the full year, we put up about 4% of volume growth, really nice progress that we saw in Europe for 2015. Application weakness, one application weakness would be oil and gas, which we experienced in 2015, we’ll probably see a bit of weakness in oil and gas for this year as well. Our China volume last year we're up. China volumes were up also in the fourth quarter along with profitability. The Russian economy and the Brazilian economy are pretty difficult, but we have unique position there, and unique cost position that's actually done quite well from a profitability and commercial point of view as well. So I'd say we're cautious, but things are progressing pretty well even as we get off to the start here in 2016.

The next question comes from Kathryn Thompson of Thompson Research Group. Please go ahead.

Hi, thanks for taking my questions today. First, on the Composite position, how much would the Ahlstrom acquisition contribute to your 2016 segment earnings? And if you could give a little bit more color on the potential contribution and answering why now in terms of their willingness to sell? Thank you.

Yes, Kathryn. So I'll take the first part of the question and I'll let Mike come in and ask the why now, or answer the why now. Again, the acquisition itself is about €73 million, a little less than one time sales. We expect to get the deal closed in the second quarter so it's still subject to regulatory approval. From a current year perspective, I think it's not going to be really anything to talk about from an accretive point of you. But as we move into 2017 and get the full year affect and slowly start to bring down synergies. It's going to be a nice deal.

And then just some comments about kind of why now, I think your question was probably more from the Ahlstrom perspective on why now than from our perspective. And I think if you look at what Ahlstrom had to say, I think they're refocusing their business and as a result decided they didn't want to be in the fiberglass Composite business. We obviously, just being a core business of ours and something we're the market leader feel like people who want to exit this business, we're the logical home for these assets. So it was a wonderful opportunity for us to extend our European business to the East and to the North. Our non-wovens business and fabrics business is primarily in Western Europe. This puts us in the Finland, it puts us in the Russia, it puts us into some new end use market. So it was a very good fit with our footprint as well as our expansion of our non-wovens business with the Gastonia investment. So it was really a logical next step for us in terms of building out and strengthening our downstream businesses or our value added businesses. And I think there was a good meeting of the minds between us and Ahlstrom that now is a good time to do this.

Great. On Insulation, could you give more color on the driver for the decision to discontinue third-party contracts? And how much did pricing or other factors take into that decision? Thank you.

Thanks for that question. We have from time to time manufactured product for third parties under other brand names. That's the business that kind of built up over the course of the last three or four years when an industry is going through a very challenged time. It's a pretty logical effort to try to optimize your business that you would try to use some contract manufacturing to maybe load assets that were underutilized then we were the beneficiary of some business in that regard. I think if you look at some of the things we showed at our Investor Day, we think we're in a business kind of in that transition point now ongoing from looking forward to the volumes that will load our assets to trying to figure out how we meet growth in the new construction market that should load our assets and potentially produce better margins for us. So there was going to come a point in time where it made more sense for us to have our capacity available to us in order to support the growth of our customers. We worked our way through some of these agreements at the end of last year and concluded that it was in the best interests of our shareholders of our business forced to take the capacity back to make it available to support our own growth. To give you kind of an order of magnitude, we described a line in the industry is being about 100 million pounds. We had about one line of capacity spread throughout our network that was subject to contract manufacturing. We also said in the last Investor Day that 100,000 units of growth in new starts produces 215 million -- 200 million pounds of end use demands. So if you kind of work your way through that map, 100,000 units of growth are a little bit more which is consensus at our market share level would require us to need about a line of available capacity in any given year to support our portion of the growth. So we're looking downstream in terms of '16, '17, '18 and think how do we want to position our assets and now seems like it's a good time to do that. Obviously, the challenge for us is we have been growing the business at about $100 million the last few years. I think we get a little more cautious outlook related to contract manufacturing today saying, we expect overall revenue growth this year will be a little bit below what the three-year trend was. But I think it is back on trend as we see new construction growth beyond '16.

The next question is from Ken Zener of Keybanc. Please go ahead.

Just sticking with the Insulation, could you comment on -- you talked about perhaps a little lower pricing, which would seem to go to perhaps lower than that 50% leverage, that long-term target. Could you kind of break that -- the pricing, discuss what's happening there? How that relates to perhaps lower new construction than people had initially expected a year ago and/or how much of that price? I would think by not doing third-party contracts, you would actually have a richer margin there rather than it -- obviously, it sounds like you lost some volume leverage there. But could you go into the pricing in the EBIT leverage a little bit more? Thank you.

Sure, happy to do that. Let me just back chart for a second and talk just about operating leverage broadly. We've said this under the calls that there has been kind of three phases. Operating leverage, know the real depths of the downturn. We had hot assets that were underutilized and basically our marginal cost in production was relatively close to zero. So any time you saw any growth at all and you could load hot asset you could get the marginal contribution against really, really good marginal economics. And we were able to get some early operating leverage by doing that even though the margins in the business were pretty lousy. As we got into kind of the mid stage, we started to get back to some level of profitability at the variable cost level and then at the fixed cost absorption level. So you could get some growth that both gave you some cost absorption, actually the growth could contribute some amount of earnings and then we started to see some pricing that also helped us sustain 50% operating leverage over the last couple of years. We're not kind of entering a stage where our assets are a bit better utilized. The business at the manufacturing level in U.S. new constructions is profitable at the manufacturing level. So growth produces some amount of earnings from volume growth, but really we're at the stage now where to stay on track with our operating leverage guidance we're going to need to see some acceleration of price. If you look at 2015, we didn't really see an acceleration of price. We had decent price performance in the first part of the year, but in the middle of the year where in prior years we had had some decent success on pricing.…

Thank you. I do appreciate that clarity. Looking at Composites, with Ahlstrom selling its assets, the success of your Brazil assets despite a very difficult end market, points to the fact that you guys operate well outside your country as opposed to some of your foreign competitors, I would say. With Ahlstrom selling, with your ability to execute better in Brazil and probably in some other markets where people are producing let's say from Chinese assets, what is that really saying? If we could take a step back about how the overall composite market is consolidating and/or the Chinese inability to really execute very efficiently outside of their home country. I mean, what does that broadly mean? With pricing and volume being very good, your margins indicate that's very good, it seems like we're approaching a point where if there's some new capacity, is there going to be something irrational? I know there's stuff you talked about with North Carolina, with the Chinese, but it seems that's very well structured industry right now and in fact, it's moving in your favor due to what we're seeing out there. Is there anything that would really concern you if capacity additions were to come on or volume or specifically, the Chinese currency were to devalue? Thank you.

Mike this is - Ken, this is Mike. I think what we have seen over the last couple of years is a validation of our strategy, which has been very much of an in-country for-country manufacturing strategy. So we never believe when we saw the huge buildup of capacity in China during the 2000s that there was enough factory cost advantage or relative cost advantage of manufacturing all the world's glass in China and shipping it all over the world. We obviously got well ahead of ourselves in terms of industry supply, but there was a glut of capacity in China in 2009, and we needed to see industry growth both in China and outside of China to get back to some level of reasonable balance. Through that period of time, we invested in China to meet the demand that we saw in China, we invested in Russia to meet the demand we saw in Russia, we continue to invest in Brazil and India to meet the demand we see in those countries within low cost, and Europe and the U.S. And we think we are returning back to an industry that looks more similar to what we would had seen in the 80s and the 90s than what we saw in the 2000s, which is generally glass manufactured and consumed in a regional economy is the best match. So when you look at where we are today, even in Brazil and Russia, those are tough economies right now. But to Michael's point, we are the largest scale manufacturer in each of those two economies and they are generally import economies. As the economy has weakened and the currency has weakened, it's very difficult for import manufacturer to compete in those markets. We have a nice cost position, because our costs are denominated in local currency. And as a result, we are able to service the local market. And if we have excess capacity, we are able to export. We see the Ahlstrom deal pretty similar to that, so we are buying assets today in Finland and Russia. Obviously, we took a lot of thought into putting additional capital into Russia, but we have low-cost glass manufacturing the Russia which will be the feedstock to the Ahlstrom asset that we intend to buy in Russia. So we do believe we'll have a vertically integrated kind of ruble denominated asset in Russia. That will give us a good opportunity to serve the Russian market, which is quite big and non-woven, and also give us capacity to potentially be exported. I'll say the same thing about the assets outside of Russia. So our overall strategic philosophy in global businesses has been kind of in-country for-country. And I think you've seen over the last four or five years, not without some pain that that strategy is the right strategy to fit the dynamics of the markets we are in.

The next question comes from Al Kaschalk of Wedbush Securities. Please go ahead.

Good morning, guys. I just want to focus on the Roofing side, just a clarification. It sounded like the sell-through was stronger than expected and there was some explanation, or there was an explanation for some of the benefit for weather. But could you maybe just account for the volume difference by either an end market, whether that's R&R or whether that was storm-related activity?

Well, we do our own analysis, which we publish of overall Roofing volumes where we break it down by new construction versus classical R&R versus storm-related demand, either major storms or where we think storm activity or weather has had a contribution to improving the market condition. We actually believe what we saw in terms of the growth in 2015, which was about 4% or 5% overall growth in shipments by all Roofing manufacturers including ourselves, is that the bulk of the growth probably came in the new construction segment where we saw housing start off about 10%. And then in classic repair remodel segment, people were placing roofs that have just aged out. We took some confidence from the fact that business stayed strong through the fourth quarter. I think on the one hand you can say, well, we had kind of favorable weather and the weather was kind of mild then it extended the Roofing season. I can tell you probably three of the last four years, this is my estimation. The Roofing season probably stopped just as much, because there was no demand out there as it did stop for weather. So we had contractors that were being reported back to us, because they said very weak backlogs at year-end. So even if the weather had been favorable, they didn't have a lot of work to go, get done. I think the fact that favorable weather caused more work to get done, would suggest that on the other side of the contract, there are more home owners who are interested in improving their house. Now, we do think some of the work that got done in the fourth quarter, at some point, will come out of 2016. So we are off to a decent start in the first part of this year. Contractors are reporting reasonable with backlogs, but its possible that as they worked their way through the 2016 backlog, the fact that we got ahead of the curve at the end of 2015, may suggest as we get to the second half of 2016. We won't see as much growth, but overall we are looking for probably some growth in the overall market which would suggest growth in new construction maybe flat to a little bit down in that classic reroof market with a stable storm-related or weather-related market.

That's very helpful. Just on Insulation side, this is my read into your commentary, but I would appreciate some additional color on there. It would suggest that maybe there's a slower take-off or sell-in the market over the last couple of months, maybe since the Analyst Day. And then what does that imply in terms of on the volume and pricing side? Are you suggesting that your end market or the builders in particular, are taking a little bit more of a wait and see approach in terms of how the construction season develops, hence the caution on the outlook on that particular sector?

Yes. Obviously, our fourth quarter revenue performance in Insulation was probably a bit below the expectation as we said either on our third quarter call on Investor Day. I think that's primarily related to construction cycles, maybe gaping out a little bit in the second half of the last year. So we model our business on the assumption that 90 days after housing start is when you see Insulation demand. And that's been through time, a pretty good relationship. I think that relationship maybe extended a bit in the second half of last year. We've heard that from other sectors of the building materials industry. We track labor growth and if you look at some of the trades, they will be important to Insulation demand. You didn't see much labor growth in framing contracting in the second half of 2015, which we suggest maybe there is some bottlenecks out there in terms of framing, some bottlenecks in terms of getting Insulation done. So I think the good news would be that suggest there is some demand that we would have expected to see in '15 that's carried over into '16. Said the other way though, once those bottlenecks start to emerge, they can cause the cycle for construction to push out a little bit. So we gave our guidance for 2016 under the assumption that cycle is relatively stable, but maybe a bit elongated in terms the demand that we would see. Overall though, we are pretty bullish on housing. Obviously, it's hard in today's environment with as much financial market volatility as we have seen in the last four or five weeks to make a near term estimate of how that affects consumer confidence and the confidence of a home owner to buy a house. But certainly the underlying indicators of traffic, homeowner intention to buy, affordability, some of the other things that drive housing have continued to improve and we would suggest that we will see another year of good housing performance this year.

The next question is from Keith Hughes from SunTrust. Please go ahead.

Thank you. Two questions. First, on the rebuild schedule for 2016, from a cost perspective, how is that going to change incrementally 2016 versus 2015? And then second question on currency, heard Composites a fair amount this year. As you look at currency rates where they are now, what will the impact be in 2016 as well?

Hi Keith, it's Michael. Thanks for that. From a rebuild expense perspective, year on year, so '15 versus '16, broadly flat. And then from a currency perspective, a significant headwind obviously in 2015, it will be just a slight headwind in '16.

Let me just add one there. The one place we probably will see a bit of currency this year that will end up talking about as we go through the year would be in our Insulation business. The Canadian dollar has gone very weak as most of you know. We have a decent business in Canada. So we didn't quite see that through all of '15 and I think we are going to see a bit more of that in '16. The Euro dollar which was the big theme for us, in '15 seems like it's primarily in the rear view mirror but some of the Canadian dollar effects will still come through Insulation business in '16/

And specifically for Composites by $9 million to $10 million, headwind this year

Just like to sneak another one in on Composites, the rebuild. You've done a lot of rebuilds by the time we get to the end of 2016. Beyond that, will that ramp down substantially in subsequent years?

Yes, so it will begin to ramp down as we move into '17.

The next question comes from Garik Shmois of Longbow Research. Please go ahead.

Hi, thank you. I'm just wondering if you could talk a little bit about mix in Composites and how you're viewing that in 2016? And then specifically, to some of the seasonal components, if I remember correctly, the beginning part of 2015 had some significant benefits from product mix that potentially could be a headwind in the first half. Just wondering if I remembered that correctly in how you're viewing mix and the evolution of mix against the comp as you look out over the next several quarters?

That’s a great question, so let me talk at a high level and then I’ll come down and actually talk specifically to some of the specialty glass sales that we had in 2015. At a high level our assets are generally running at high utilization and that’s across regions but also across product lines and so we are seeing some tightness. And so therefore our commercial teams are focusing on our business, it tends to be a higher price and therefore higher margin products. We also had a pretty successful pricing and margin enhancement efforts that’s been underway for the last couple of years really getting our commercial teams to be better at selling in higher margin products. And then if you remember from Investor Day one of the key themes that we brought forward was our focus on new product introductions and those new product introductions are tend to carry higher margins and products that they are replacing. And then lastly specifically around specialty glass sales from last year, we don't expect that to repeat and that’s about $60 million.

Okay. Thank you. And then secondly, I was wondering if you could comment a little bit on Roofing inventories, just given the strong sell-in in the fourth quarter. Are you seeing any excess channel inventories for Roofing? If I remember correctly, you entered 2015 with relatively low inventories and that turned out to be favorable for yourself and the industry. Just wondering if you could also talk about where you're seeing inventories right now and how you expect the progression to move through 2016.

I mean we don’t have great visibility to inventories but we have good relationships with our customers and have kind of ability to evaluate what we think is going on out there. Obviously the fact that we continued to shift relatively good volumes through the fourth quarter would suggest to us that inventories are on very good shape at the distribution level. I mean typically most of our customers are in calendar year given the dynamic of shingles, most of them do not have huge incentive they want to carry excess inventory the year end that's when they do their financial results, that’s when they report to the borrowers. And then also that’s typically when their business is the weakest. So that would be the time of the year were our experiences in the industry tries to drive to all levels of inventory and yet we were seeing pretty broad based shipments geographically by channel through December suggesting most of our customers were where they wanted to be on inventories when we entered this year in a solid position.

This is Thierry, we probably have time for one more round of questions.

The next question comes from Philip Ng of Jefferies. Please go ahead.

Hi, guys. Thanks for squeezing me in. Some of the mothball capacity that came on last year in Insulation may have weighed on pricing. Is that largely absorbed at this point? Can you talk about how the industry is behaving? Is there opportunity for two price increases like in years past?

This is Mike. I think that we framed our kind of view of the industry and how we see kind of our position in the industry. We do believe and has held to a position that the fact that Insulation prices are still so far below where nominal prices were a decade ago. Is there a real problem for our business and then we need to get pricing back to levels that would reassemble where we were in the last cycle in order to get profitability back to reinvestment economics? I think Michael use the phrase that our product is useful and undeniably valuable. I think that that’s a simple description of how we should think about the Insulation business. That said, it’s a competitive market, and we have not yet seen the real acceleration of pricing that maybe our analysis would suggest should come at some point in this cycle. So we continue to go out there and fight for every order, and believe that we can grow our business at the topline and at the EBIT line in 2016 and beyond. But we still have our eye for the long term, I guess for the mid-term. I'm trying to get back to pricing levels that will support higher levels of profitability to give us some return on the challenges that we experienced over the last decade where the business didn’t performed very well.

Got you. That's helpful. And I guess bigger picture, in the next leg of growth on starts, I would imagine you're going to have to bring on some higher cost capacity on the mothball side. Are you thinking about bringing that stuff on a function of getting a proper return before you actually pull the trigger and holding back on maybe seeing some volumes and taking the price over volume? Can you talk about how you approach that? Thanks.

I mean, we’ve said it’s going to be a difficult to want to go back and turn on a facility that has been shut down. I mean, we tend to think of our shutdown facilities the same way the utility industry would think about peakers, which is you’re going to bring them on, they’ll probably run for a period of time, but then if the economy rolls over and you start to see a decline in housing, those are also the facilities that are going to shut down quickly. So you need to be able to make a quick, simple return in cash on cash. And certainly today, we are not close to that. I think what Michael shared in terms of contract manufacturing, has given us some availability to some low-cost capacity that is now back inside our supply chain. So the next tranche of growth that we see is low-cost assets that we were using to service the contract market which will not be available to us to support growth over the next couple of years. So we backed down there a little bit to make sure that we could have our own low-cost capacity available for us to serve to our customer. So we are managing that balance in our supply chain, and we believe that we’ve got our assets very well positioned for how we see the recovery playing out in the next couple of years.

This concludes our question and answer session. I'd like to turn the conference back over to Thierry Denis for any closing remarks.

Very good. Well, thank you everyone for joining us for today’s call. And with that I’ll turn it back over to Mike Thaman, for a few closing remarks.

Sure Thierry, thanks. Obviously, we are very proud of the results that we reported today. Owens Corning had a great year. We saw all three businesses show very, very good improvement. As a corporation, it was our all-time record year in terms of EBIT growth. But in addition to the strong EBIT growth in all three of our businesses, the strong earnings growth, as Michael noted, we also had very strong free cash flow which is then a focal point for the company over the last two or three years of getting on to a little bit better cash conversion. So from a financial performance, and a diversity across our mix of businesses, and across our portfolio of companies or businesses, we really feel like 2015 was a great step forward for our company. We think 2016 is going to be another similar big step forward. We expect all three businesses to again, show year-on-year improvements in earnings and some growth. We'd expect to see Owens Corning show strong EBIT growth as evidenced in some of the conversations we had today about our outlook. We'll reserve fully quantifying what we think that EBIT outlook will be later in the year so we get better visibility. I'd say probably to the evolution of the Roofing market to the first half, as well as the evolution of Insulation volumes and pricing as they progress through the first half of the year. So I think we’ll get better visibility probably as we get into our second quarter earnings call. I think we are appropriately cautious. Given the uncertainty, we see in the global economy today, and the volatility of some of the markets but we are also quite confident that the businesses are performing at high levels and that we can produce very good returns for our shareholders, irrespective of the fact that we are in a little of a challenging, and somewhat choppy marketplace. So, we're looking forward to 2016. We appreciate your ongoing support, and we look forward to talking to you again on our first quarter call. Thanks

The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
