Albert?.

Thank you, Jeff. Good morning, ladies and gentlemen, and thank you for joining us to discuss our first quarter 2018 results. In this morning's press release, we reported quarterly net income of $287 million for the first quarter of 2018 or $2.20 per diluted share.

Excluding the one-time impact of the tax reform in the fourth quarter of 2017, this quarter's net income of $287 million will be a record for Westlake.

First quarter 2018 income from operations of $401 million and EBITDA of $579 million were also records for Westlake, as we benefited from strong demand for our products and the operational improvements resulting from the investments we made in 2017, to improve the reliability of our acquired assets and catch up on deferred maintenance.

We continue to see solid demand for all our major products, including polyethylene, caustic soda, and PVC, as a result of synchronized economic growth in Americas, Europe, and Asia.

Our Vinyls segment benefited from the recently rationalized European chlor-alkali capacity and curtailed production in China, both of which were driven by environmental regulations, tightening global supply. The onset of new ethylene supply with a start-up of a number of ethylene facilities in U.S.

Gulf Coast reduced our purchased ethylene costs and increased our margins. Our Olefins segment continues to see tight supply for some grades of polyethylene and good demand as the industry recovered from Hurricane Harvey. I would now like to turn our call over to Steve, to provide more detail on the financial and operating results.

Steve?.

Thank you, Albert, and good morning, everyone. I will start with discussing our consolidated financial results, followed by a detailed review of our Olefins and Vinyls segment results. Let me begin with our consolidated results.

This morning we reported net income attributable to Westlake of $287 million or $2.20 per diluted share for the first quarter 2018 on net sales of $2.2 billion. Westlake's first quarter 2018 net income increased $149 million compared to the first quarter 2017 net income of $138 million or $1.06 per share on sales of $1.9 billion.

First quarter 2018 record operating income of $401 million increased $167 million from the first quarter of 2017 operating income of $234 million.

Compared to the prior year period, the first quarter 2018 benefited from higher prices and margins for our major products, higher sales volumes for caustic soda and PVC resin, lower costs associated with planned turnarounds and unplanned outages and a lower effective tax rate as a result of tax reform.

Fourth quarter 2017 net income included a one-time benefit of $591 million associated with federal income tax reform. Excluding this one-time benefit, our first quarter 2018 net income of $287 million or $2.20 per share increased $76 million from the fourth quarter 2017 net income of $211 million or a $1.62 per share.

Our record operating income for the first quarter of 2018 of $401 million increased $38 million compared to fourth quarter 2017 operating income of $363 million.

The increases in net income and operating income in the first quarter of 2018 are primarily a result of increased sales volumes and margins in our Vinyls segment and lower costs associated with planned turnarounds and unplanned outages, primarily offset by lower polyethylene sales volumes as we are preparing for planned turnaround in the next several months.

Now, let's move on to review the performance of our two segments starting with our Olefins segment. In the first quarter of 2018, the Olefins segment reported operating income of $163 million, a decrease of $17 million from the first quarter 2017 operating income of $180 million.

This decrease in operating income of $17 million was mainly attributable to lower polyethylene sales volume and higher ethane feedstock cost, partially offset by higher polyethylene sales prices. First quarter 2018 operating income of $163 million decreased $3 million compared to fourth quarter 2017 operating income of $166 million.

This decrease in operating income was primarily due to lower polyethylene sales volumes, partially offset by higher styrene sales volumes and prices. Now, let's move on to the Vinyls segment. First quarter 2018 Vinyls income from operations of $266 million increased $196 million from first quarter 2017 income from operations of $70 million.

This increase in operating income was due to higher sales prices for major products, higher sales volumes for caustic soda and PVC resin, lower feedstock cost and lower costs associated with planned turnarounds and unplanned outages compared to the prior-year period.

First quarter 2018 operating income of $266 million increased $52 million from the fourth quarter 2017 operating income of $214 million.

This increase is a result of higher sales volumes for caustic soda and PVC resin, higher sales prices for caustic soda, lower feedstock cost and lower cost associated with planned turnarounds and unplanned outages as compared to the prior year. Now, let's turn our attention to the balance sheet and the statement of cash flows.

First quarter 2018 cash flows from operating activities were $225 million, and we invested $154 million in capital expenditures. As of March 31, we had cash and cash equivalents of $851 million and total debt of $3.1 billion. In February, we redeemed $688 million in long-term bonds associated with the acquisition of Axiall.

We have also announced another redemption of $450 million of debt that will be retired on May 15. Funds to redeem this debt will come from our current cash on hand. Following this redemption, we will have retired over $1.2 billion in debt since our acquisition of Axiall in August 2016. Now, allow me to provide some guidance for modeling purposes.

For 2018, we expect capital expenditures to range from $600 million to $650 million, which includes our normal maintenance capital expenditures, our portion of the construction of the ethylene cracker being jointly built with Lotte Chemical in Lake Charles, Louisiana and long lead equipment for our chlorine VCM and PVC expansions in Burghausen and Gendorf, Germany and Geismar, Louisiana that we announced in February.

With that, I'll turn the call back over to Albert to make some closing comments.

Albert?.

Thank you, Steve. This quarter's record results demonstrated value of our investments in the operational reliability of our facilities, while we continue to experience solid global demand for all our major products. Looking forward, we believe we'll continue to benefit from globally competitive ethane natural gas in the U.S.

as a result of expanded shale oil and gas drilling activity, driven by higher oil prices. We expect to benefit from the favorable Vinyls cycle driven by strong global demand with limited capacity additions on the horizon.

We remain focused on pursuing growth initiatives such as our ethylene joint venture with Lotte, which has a planned start-up in the first half of 2019, the 200 million pounds VCM expansions in Geismar and Gendorf, and the 750 million pounds of PVC expansions in Burghausen and Geismar.

We will continue to explore additional debottleneck opportunities and search for acquisitions that will deliver value to our shareholders. Thank you very much for listening to our earnings call this morning. Now, I'll turn the call back over to Jeff..

Thank you, Albert. Before we begin taking questions, I would like to remind you that a replay of this teleconference will be available starting today at 2:00 PM, Eastern Time. We'll provide that number again at the end of the call. Sabrina, we will now take questions..

Thank you. And the first question will come from the line of John McNulty with BMO Capital Markets. Your line is now open..

Good morning. This is Bhavesh Lodaya behalf of John..

Good morning..

Good morning..

Good morning.

First of all, can you share your thoughts on your current positioning international trade, specifically with China and how are some of the proposed tariffs can impact those flows or margins?.

Certainly, the polyethylene industry exports around 20% of our production currently. And as the new capacity come onstream, we believe that the majority of the added capacity will be exported. On the PVC side, over – about 30% of the PVC produced in the North America in the U.S. are exported.

And on caustic side, I think over 20% of the caustic produced in U.S. are exported. And in the PVC side because of our extensive downstream building product business, we tend to export less than the industry average of 30%.

And in polyethylene and caustic, while we tend to export a bit less than the industry, but we are close to the industry exports numbers. As far as China is concerned, we do not participate a lot in the China trade. I think as a company, we export between 1% and 2% of our revenue growth in China and that comes potentially from U.S.

business as well as our European business..

Thanks. A question on ethane. There have been a lot of discussions of massive new NGL capacity coming out of the Permian and as infrastructure builds up, that keeps ethane prices low even with all the new demand coming up.

Could you share your views on just of that happening and basically your long-term views on ethane prices?.

Certainly. You're actually right. There's a tremendous amount of investment going on in the Permian Basin, as a result a lot of liquids – natural gas liquids come from both oil and gas exploration over there. And there's still a lot of ethane being rejected in the system. But as you know, there's a fair amount of new ethylene capacity coming onstream.

Some has already come onstream in the last year, early this year and then between this year second half and the next year there's also more ethylene plants coming onstream, along with the export facilities. So some of the ethane demand will be increasing and will be absorbing some of the supply..

And then, finally, if I may, on the Lotte JV, is there a return on capital or a EBITDA margin floor that you would want to see for you to make that decision to add to your stake or maybe if there's a ethylene margin floor we should be thinking about?.

Well, as we continue to assess the investment opportunity that we have there, we'll continue to look at that. We don't have a fixed number in mind, but I will tell you, we'll continue to assess the opportunities that, that presents to us..

We'll be looking on the return on investment based on the long-term basis. As you know there are other new projects being announced to build new ethylene plants in U.S. So I think several companies are considering U.S. as a favorable place to putting additional ethylene capacities..

All right. Thanks for all the color..

You're welcome..

Thank you. And the next question will come from the line of Stephen Byrne with Bank of America Merrill Lynch. Your line is now open..

Yes. Thank you.

I'd like to hear your view on potential return on investment for potential new greenfield capacity in chlor-alkali, is it attractive at this point, and then to add on to that, the downstream capacity to consume those chlorine molecules in one of the derivatives?.

Yeah. We believe if you look at integrated Vinyls and to PVC including ethylene, our investments, today's return are still not at the replacement economics yet at a reasonable return on investment. But they're getting closer..

And with respect to your building products, downstream business, is there a potential monetization of that business you might consider to extract the value out of that or to separate out that business and would you consider something similar on the Olefins side, a downstream building products business?.

Well, Steve, as we think about the business downstream of our Vinyls business and the PVC building products, we think that provides a nice integrated margin. And certainly it's nice – as Albert noted, a nice off take of resin into our business. And so, we think it's a business that is interesting and provides nice integrated economics.

And so, as we think about the business, it's a meaningful business and we can think about over time providing further transparency to that business, but certainly I would say it's a nice integrated business and we think of it as an important element of our overall business.

And we would continue to think about growing that business over time, because as I mentioned, it's a very good use of the integrated resin going downstream into building products. We think it's a very valuable element of our business..

Pretty good. Thank you..

You're welcome..

Thank you. And the next question comes from the line of Kevin McCarthy with Vertical Research Partners. Your line is now open..

Yes. Good morning. In your press release, you indicate that volume in the Olefins segment declined 8.6% in the first quarter on a year-over-year basis.

Just wondering if you could speak to the extent to which unplanned outages impacted that number and if so, what the related dollar amount impact could be?.

So Kevin, this is Steve. As we mentioned earlier we've got a number of planned turnarounds in polyethylene during the course of the rest of this year and certainly, we were building some inventory to deal with that planned turnaround in polyethylene.

And so the impact I noted is that $17 million impact as we continue to build some inventory for the planned turnaround activity later this year..

Okay. Then the second question I guess for Albert on capital deployment, your net debt is down about $943 million, it looks like over the past 12 months. So folks have already asked about you know organic reinvestment here on the call.

What do you see in the external market, and how should we think about your balance sheet and capital availability versus what you see on the M&A front at this point?.

Certainly as Steve reported, we have a $600 million-$650 million capital program going on, trying to finishing the ethylene joint venture, we have with Lotte. And as you know we also have an option to buy up to 50% of that JV, within three years of the plant start-up.

So certainly those are our capital needs going forward if we elect to choose to exercise the option. We have ongoing expansions as we mentioned in Burghausen in Germany, Gendorf in the U.S., and we're looking for further debottleneck opportunities.

Naturally, we always look for opportunities of acquisitions in the Olefins and Vinyls business and we'll continue to explore those and as Steve mentioned, the building products business is over $1 billion revenue, out of our total revenue of over $8 billion, and it's an area we want to grow that business as well.

So we are comfortably looking for opportunities to add value to our shareholders..

And lastly, if I may you referenced the benefit from ethylene monomer, in light of your current short position there.

How should we think about your procurement there in terms of spot versus contract mix and benefits going forward?.

Certainly, we buy a mixture as you expected, we highlighted some of those contracts on the Axiall and we buy a mixture between spot and contract, but we are benefiting from the lower ethylene prices both in spot and contract and hence, we are the second largest ethylene buyer in the U.S. and we're enjoying the lower ethylene prices..

Okay. Thank you very much..

You're welcome..

Thank you. The next question will come from the line of Neel Kumar with Morgan Stanley. Your line is now open..

Hi, thanks for taking my question..

You're welcome..

Given the widening price spread between membrane and diaphragm caustic, do you see the possibility of customers switching to diaphragm caustic?.

Well, certainly, every customer wish to minimize their cost and those customers that can use diaphragm would enjoy using diaphragm..

Okay. And then I guess just a follow up on ethylene.

What is your outlook on ethylene prices in the second half of the year? And do you see the recent weakness in ethylene prices leading to lower PVC prices?.

Yeah. Personally, I think the current ethylene price is reasonably low, I think due to various reasons. I think more of the reason is the derivative plants which were built along with the new capacities are now operating at a full rate, so it can not absorb the ethylene, we do not anticipate ethylene to be that low for a long time.

And I think IHS is forecasting ethylene price, spot price go back again second half..

Great. Thanks..

You're welcome..

Thank you. And the next question will come from the line of P.J. Juvekar with Citi. Your line is now open..

Yes, hi good morning..

Good morning, P.J..

You are 1.8 billion pounds short on ethylene and ethylene has been dropping quite rapidly since first quarter, more in second quarter. How much benefit did you get in the first quarter? And your ethylene prices went up, but there should have been an offset from falling ethylene.

So can you quantify that ethylene benefit?.

So P.J. as I think about the benefit here, as you know, when I think about our Olefins situation in ethylene, it's looking at ethane all the way out to polyethylene. And so in that segment of the business we're really integrated.

So the benefit that we see is really in our Vinyls business and as Albert noted, we're the second largest buyer of ethylene in the North American market buying over 1.8 billion pounds to 1.9 billion pounds currently a year.

And given that, that business remains strong, we continue to see the benefits accruing really to our Vinyls business and we're looking forward to the ability to really capture that value in ethylene in our Vinyls chain..

And any benefit from that will flow to cost of goods sold which in the inventory and then it comes out afterwards..

Okay, thank you.

And what's happening to polyethylene? Where are inventories with convertors? And do you think convertors are holding back today in anticipation of new capacity starting up?.

Certainly. Everybody likes to buy at low prices, and that actually people are surprised that we've got a $0.10 a pound price increase after the hurricanes last year, and people saw that all the $0.10 would go away and did not. And actually we had price increases in February of $0.04 a pound. And I think, partly is a good demand in the U.S.

but also partly due to good demand globally and partly due to higher crude oil prices. As you know, most of the ethylene plants in Asia and Europe and Latin America are based on naphtha crackers. And as crude oil prices jumped from $30, $40 a barrel today, Brent is what $72 a barrel.

The cost of naphtha cracking has gone up and hence polyethylene prices stay high globally. And hence U.S. polyethylene price also has not come down as people thought it will be..

Thank you. And just quickly on the alumina market. With the tariffs that are being proposed on aluminum, how does that impact your caustic market? Any thoughts there? Thank you..

Certainly. I think that we will see the impact globally of the tariffs on aluminum, but people still need aluminum and people will pay the lowest prices we can – people can. And I think the negotiation is still going on between various countries and the U.S. government.

So as we said, caustic demand is still quite strong and the price – caustic prices in Europe, I think they had $100 – €100 a ton increase at the first quarter and they still have near about €5 a ton increase in April. So, demand is strong globally and our industry is enjoying benefit..

Thank you..

You're welcome..

Thank you. And the next question comes from the line of Jim Sheehan with SunTrust. Your line is now open..

Thank you. So, on caustic soda pricing, the index went up $35 this month.

Do you expect to have more pricing traction in the second quarter for caustic soda?.

Yeah. I think the industry announced close to $100 a ton of price increase this year and we're getting a large share of that. I think most of the price increases will go through. IHS is forecasting after the $105 a ton short term price increase. The rest of the year will be flat. Now, we will see if that is the case or not..

Thank you.

And did you guys have any FIFO accounting impacts positive or negative during the quarter?.

Jim, it was really small this quarter, not material..

Thank you..

You're welcome..

Thank you. And the next question comes from the line of Hassan Ahmed with Alembic Global. Your line is now open..

Good morning, Albert and Steve..

Good morning, Ahmed..

A quick question around just moving away from the near-term, the whole sort of notion of the second wave of capacity build outs here in the U.S.

I mean, since the time that the initial announcement started coming out, obviously, it seems at least rhetorically speaking, the world's changed quite a bit, a lot of noise around trade was on the more sort of concrete side of things.

We've obviously seen energy pricing going up, steel pricing going up, potential as I said earlier, uncertainty about trade floors and the like.

What are your guys' views about the sort of 2018 through 2022-2023 time period, now with all this noise around us? I mean, on the margin, are you seeing that this uncertainty is making people rethink investing in capacity build outs in the U.S.?.

That's a very good question, Hassan. I think your source would be better than mine, since you are so such a global study of our industry. But I think that the economy globally is doing very well. I think that as you said it synchronized growth around the world.

Even though interest rate is moving somewhat higher from zero, I think the employment in the U.S. and globally it's growing. You see shortage of qualified labors both in the U.S. and Europe and even in some part of Asia.

So if we see strong demand and people are still lifting from poverty levels to the middle-class both in China and in India, and the demand for material goods are increasing, people moving from rural area to urban area. And we don't see – and U.S. by far has the lowest feedstock cost both from the feedstock or oil and gas as well as power.

Our chlor-alkali business is really power driven and we have (00:31:29). So U.S. has a very competitive position from a cost point of view. And if global demand continue to grow and with some inflation, capital investments are getting more expensive.

So people who have assets and can generate high operating rates will benefit from a lower cost and good prices..

Understood, understood. Now as a follow up, Albert, again kind of sticking to this theme of these trade related issues, as well as the feedstock side that you mentioned in your comments, recently there seems to be some decoupling between the price of crude oil and propane.

And then taking that to the next step or level, included in the Chinese tariff list were tariffs on the import of propane and as we all know obviously a lot of propane exports coming out of the U.S. due to Asia, China in particular.

So just like to hear your views on what you think has caused this recent decoupling between crude and propane? Do you think that these trade related issues are playing a role in that? And alongside that, how should we think about the interplay between sort of ethane and propane in this sort of an environment?.

That's a very good question. I think that a lot of ways the increase in production of oil gas out of Permian Basin especially as we said a lot of ethane being produced, a lots of other propane (00:33:12) being produced.

And propane compared to oil is still much easier to – it's a cleaner product, easy to ship and global demand for propane, both for fuel and for PDH are increasing. So, if China wants to have a tariff on that, they can buy it from Middle East and U.S., supply it to other parts of the world.

So I don't see the Chinese tariff will have a much impact on the global demand for propane..

Perfect. Thank you so much, Albert..

You're welcome..

Thank you. And the next question will come from the line of Arun Viswanathan from RBC Capital Markets. Your line is now open..

Hey guys. Good morning..

Good morning, Arun..

A couple of questions on the, I guess, dynamics you're seeing in the market. We've noticed some softness creep in the Asian polyethylene prices, but the industry I guess here in North America does have an increase on the table for May after a flat March and maybe even April.

What do you think the likelihood that May increases are successful in polyethylene? And then in PVC, similarly, we're going into kind of a spring building season, which could increase capacity and supply. So how do you feel about the dynamics for PVC price increases as well? Thanks..

Certainly, on the PVC side, I know some of the analysts are saying that with a lower ethylene costs in the U.S., the PVC price should come down so on and so forth. But PVC, as I said earlier, 30% of PVC produced in U.S.

are exported, it's really a global product, and we're seeing after the Chinese New Year, PVC price has come down a bit in Asia, but the recent week or so the price has returned, and the demand of PVC is strong globally. So we'll see whether people will think that PVC price will come down a bit in I think May.

(00:35:21) you're looking a penny a pound drop in May will happen or not. On the polyethylene side, as we said earlier with the new capacity coming onstream, people have thought the price will come down and instead, we had a price increase in February.

Now, those $0.03 a pound that we announced for March implementation didn't happen and the industry, some of the industry players push it to April or May. Again, some of the industry analysts are saying that they expect prices for polyethylene to drop in May or June. And as we see that some selective polyethylene inventory in the U.S.

is still quite low. So we're seeing a different dynamics in depending on the grades of polyethylene you have. So time will tell what happened to the price movements of each of these grades..

Thanks. And on the ECU margin side, it looks like caustic has gone up $35 again in April and another $15 realized on chlorine.

How should we think about how that impacts your ECU margins through the rest of the year, understanding that you're not really selling merchant chlorine, but maybe you can just give us a comment on caustic as well?.

Yeah, I think caustic and chlorine as we said, both prices have moved up and I don't think we have received the full price increase yet in caustic. So over the years, we believe that all the price increase amounts will be realized.

And so it's chlorine, and this is the – it is the high season for chlorine products including water treatment for the next few quarters. And as an industry, we should be able to benefit from the increasing demand as well as prices..

Thanks..

Thank you. And the next question will come from the line of Bob Koort with Goldman Sachs. Your line is now open..

Good morning. This is Dylan Campbell on for Bob..

Good morning..

Good morning. Previously you mentioned that we are not quite at re-investment economics, but getting closer for chlor-alkali and Vinyls.

I'm just curious kind of what capital costs you're assuming to build greenfield across that chain and then generally what the timeframe it would take to build that capacity?.

Yeah. I think typically it would take some initial planning for it – plan coming up will be at least three years to four years for a large integrated site. And there are so many plants, they're going to come in on multi reinvestment capital costs, but they're substantial..

Got it. And last quarter you raised guidance for the Axiall synergies of $250 million. What run rate were you guys at in the first quarter of 2018 for....

When I....

Go ahead..

When I think of this savings, the numbers that we've been talking about are the actual dollars achieved what I call in pocket, not so much a run rate. And so, given the $250 million guidance that we've given for the year, we'll continue to work on that incremental $80 million.

And as you can imagine we continue to focus on that every day is we want to achieve that. Our objective is to achieve as much of that as quick as we have. But we haven't given a specific run rate..

Got it. Thank you..

You're welcome..

Thank you. And the next question will come from the line of David Begleiter with Deutsche Bank. Your line is now open..

Thank you. Good morning..

Good morning, Dave..

Albert, looking a little bit longer term, there's been some discussion about the IMO 2020 self-regulations, that they might lead to actually increased naphtha production and hence lowered naphtha prices beyond 2020.

How do you think about that and do you concur with that view?.

Yes. I think that is the position people are taking and there'll be more naphtha available and I don't know exactly how much more naphtha is available, but in the U.S. ethane is still the preferred feedstock, I don't think naphtha will make much inroad into the feedstock in the U.S. and overseas depending on what crack is available.

If there are no new crack, no new naphtha crackers build, even though you have a cheaper feedstock, they're not going to consume more naphtha..

Very good.

And just on styrene, were you surprised by the recent announcement of a study to look at new styrene capacity by another producer in the United States?.

Certainly. Interestingly, our styrene monomer plant was started in 1992 and that's the newest styrene plant in the U.S. And because of a lack of new investment, today styrene business doing quite well and operating rates running very high.

So, if you look at the pricing economics, the numbers we should justify, the question is, how long will that styrene markets be that good, and I know there are plants that are being built in Asia. So....

Thank you..

You're welcome..

Thank you. And the next question will come from the line of Aleksey Yefremov with Nomura Instinet. Your line is now open..

Thank you. Good morning, everyone. Albert, you were discussing debottlenecking opportunities that you haven't announced yet.

Are those debottlenecking opportunities potentially larger than the recent ones that you've announced and what's potentially the timeline for those?.

Well, we're continuing, Aleks, to really assess the returns on these. As Albert noted, if we continue to debottleneck recognize, those have to be justified in export economics and so we want to make sure that we have a very good handle on, not only the capital cost, but also the return.

And as you know, we're very focused on a return for any investment that we make. So we're continuing to study this. We want to make very comfortably sure that we can get the kind of returns if we choose to move forward with any expansions and debottlenecks..

Hi, guys.

Is it fair to characterize those as incremental debottlenecks?.

Yes..

Yeah. They would be. As you can see we've already announced some and we're continuing to study others. But it's really, as I noted early in my comments, it's a return focus. We want to make sure we have the right returns for any capital we deploy..

Thanks, Steve. And if I can follow-up again about reinvestment economics question, if I got it right, Albert, you were talking about the chain that includes ethylene, PVC or Vinyls and chlor-alkali.

If we were to look at just Vinyls plus chlor-alkali with ethylene being purchased, do you think the returns are there for a project like that, currently at current prices?.

Well, it's the DCM PVC, and if you're looking at power plants associated with chlor-alkali, we don't believe that even without the ethylene, the economics is there yet..

Got it. Thank you..

You're welcome..

Thank you. Our next question will come from the line of Matthew Blair with Tudor, Pickering, Holt. Your line is now open..

Hey, good morning Albert and Steve..

Good morning..

...Matthew..

I was hoping to talk about some of the dynamics in building products. It seems like demand should be pretty good here just given some of the housing start numbers that we've seen.

But then, I think there could be the potential for elevated costs just given that I think a large percentage of that product is trucked out and we've seen a lot of reports on elevated trucking costs.

So, could you just talk about the interplay there? And maybe just directionally, are you seeing higher building products margins now than a year ago?.

Certainly, the building products demand has increased over a year ago. By the way, building products not only associated with newbuilds also with replacements, refurbishment, so that's for both sides. And because of the cold winter, I think the season for our new homes has been delayed somewhat. And I think they're getting back to the high season now.

I think that – as you said, you're absolutely right, the trucking costs most of the building products are shipped by trucks. The lack of truck availability and the higher trucking costs will increase the cost of the products. And also with the newbuild, the lack of availability of labor to build new homes also is an issue.

So there are headwinds from that side. On the other hand, the demand the 50 year average demand for residential units is 1.5 million units and 2006 were 2.3 million units and now it's just going between 1.2 million, 1.3 million. So we're below the 50 year average. And meanwhile in 50 years, the U.S. population has increased on the average.

So we think the demand is there and it just takes time to get the U.S. home buildings to get back to the normal run rate..

Great. Thank you.

And then the $15 price increase in chlorine, Albert, in your opinion, what are the main drivers there? Is that really coming from PVC demand or are you seeing elevated demand in other chlorine derivatives?.

Yes, both. I think demand both in the U.S. and overseas demand for chlorine products has increased and chlorine price hasn't really changed for a long time. And I think the $15 should be straightforward increase..

Understood. Thank you..

You're welcome..

Thank you. And our next question will come from the line of John Roberts with UBS. Your line is now open..

Thanks. Hi, Albert and Steve. A nice quarter..

Thank you..

Good morning. Thank you..

Good morning..

There's been a lot of discussion about vinyl and caustic capacity curtailments in China with all the new environmental rules, but at the IHS conference recently they talked about a number of new carbide-based plants that will startup over the next few years, because they were permitted in before the new rules and grandfathered in.

So do you think production of vinyl and caustic in China goes up over the next few years, which I think is what IHS is looking forward or do you think it's going to be more flat or even down, which I think is kind of what people had been talking about?.

That's a good question. You're right. Some of those plants which are permitted under construction before the moratorium will go through, but they will replace some of the older smaller plants which are still running higher cost plants.

So time will tell whether the net-net production in China will be flat or grow a little bit, we expect to grow a little bit, because Chinese demand is still growing very fast and global demand, India, it's a huge market and Middle East in many parts of the world. And really there's no new capacity added.

So even with the Chinese capacity added, it will not be sufficient to meet the demand increase on a global basis..

Thank you..

You're welcome..
