Thank you, Jeff. Good morning, everyone, and thank you for joining us to discuss our fourth quarter and full year 2020 results. Before we get into our results, let me provide some context as to how we approach dealing with the challenges in 2020. 2020 was clearly an unprecedented year and one where our priorities were to protect the health and safety of our employees, deliver on our commercial commitments and strengthen the company. I'm very appreciative of our employees who continue to work day in and day out, particularly those in our plants and production facilities. Our facilities are a crucial component of the infrastructure that provides key products to our customers, who assist in the pandemic response, keeping essential goods and services flowing in support of our economy. We have also made progress this year developing products and solutions for a more sustainable future while protecting and investing in our people. We look forward to further discussing these products with you later this year. These initiatives reflect our commitment to being a responsible corporate citizen. Let me now turn to review the results. In this morning's press release, we reported net income for the fourth quarter of 2020 of $113 million or $0.87 per share, and full year 2020 net income of $330 million or $2.56 per share. Before Steve goes through the fourth quarter and full year results, let me provide some insights into the year. The effects of COVID-19 weighed heavily on the global economy early in 2020. But starting at the end of the second quarter, we saw the beginning of a strong global demand recovery for PVC, polyethylene, and our downstream building products. With a strong rebound in demand, we were able to capitalize on the increasing price environment that drove improving product margins for PVC, polyethylene, and our downstream building products. In August and October, two major hurricanes made landfall in Southwest Louisiana. While our plants weathered the storms well, there was extensive damage to the power and utility infrastructure in the Lake Charles area. Once utilities were restored, we worked tirelessly to restart operations. In spite of production constraints caused by the hurricanes, we worked diligently to serve our customers. I'm particularly thankful to our employees for their dedication who were also impacted by these hurricanes while working to restore our operations. While we did experience production constraints in the second half of the year due to the hurricanes, we're able to benefit from the continuing growth in global demand. This translated into strong sales volumes for most of our products, driven by strong demand from product packaging, housing, and automotive sectors. This was especially true as new housing starts, repair, and remodeling activities generated robust demand in our downstream building products business. I would now like to turn our call over to Steve to provide more detail on the financial and operating results for the fourth quarter and the full year.

Thank you, Albert, and good morning, everyone. I will start with discussing our consolidated financial results, and then go into a more detailed review of our Vinyls and Olefins segment results. Let me begin with our consolidated results. Westlake continued to benefit from the improving market dynamics for most of our products, beginning late in the second quarter of 2020, with strong demand and increasing prices for most of our major products. The effects of the two hurricanes, including the idling of our facilities, impacted our business beginning late in the third quarter due to lower production and sales volumes, and increased maintenance expense, as a result of the hurricanes. For some units, these outages stretched into November. While we have fully resumed operations following the hurricanes, we estimate the impact to our fourth quarter pretax earnings from the lost sales, increased cost, and higher maintenance expense resulting from the storms to be approximately $120 million or $0.96 per share. Of this $120 million estimate, approximately 75% was related to our Vinyls segment, with the balance affecting our Olefins segment. The full year impact of both storms on our results was approximately $220 million. For the fourth quarter of 2020, we reported net income of $113 million or $0.87 per share compared to net income of $72 million for the fourth quarter of 2019. These results are inclusive of the hurricane impact of approximately $0.96 per share from the hurricanes I just mentioned. The $41 million fourth quarter year-over-year increase in net income is a result of higher sales prices and margins for polyethylene and PVC resin and higher earnings resulting from robust demand in our downstream building products business. Partially offsetting these increases were lost sales and lower production volumes and other costs related to the two hurricanes we previously mentioned, as well as lower sales prices for caustic soda. Fourth quarter 2020 net income increased by $56 million from third quarter 2020 net income of $57 million. The increase in net income was largely attributable to higher prices and margins for polyethylene and PVC resin as well as lower restructuring charges. Offsetting these increases were lower sales volumes resulting from the impacts of the hurricanes, lower caustic soda prices, and higher fuel cost. Our utilization of FIFO method of accounting resulted in an unfavorable pretax impact of approximately $18 million or $0.11 per share compared to what earnings would have been if we reported on the LIFO method. This is only an estimate and has not been audited. Let me now move on to review the performance of our two segments, starting with the Vinyls segment. Throughout the fourth quarter, we saw strong global demand for PVC anchored by increasing global construction activities. Our downstream building products businesses continued to see strong consumer demand, driven during the fourth quarter. This robust PVC demand was driven by global residential construction, automotive, medical and appliance industries. While the effects of the hurricanes impacted our production of PVC and limited our PVC sales, we benefited from strong margins during the quarter. For the fourth quarter of 2020, Vinyls operating income of $166 million increased $98 million from the prior year period, primarily as a result of higher sales and margins for PVC resin and higher earnings in our downstream building products business, which were partially offset by lower sales volumes and loss production resulting from hurricanes, lower sales prices for caustic soda, and higher fuel cost. For the fourth quarter of 2020, Vinyls operating income increased $124 million from the third quarter of 2020, primarily as a result of higher sales and margins for PVC resin and lower restructuring costs, partially offset by lower sales volumes resulting from the hurricanes, seasonally lower sales in our downstream building products business, and higher fuel cost. Now, let me turn to our Olefins segment. In our olefins business, robust global demand for packaging and nondurable products expanded our margins in polyethylene. As the effects of the hurricanes limited our production and sales volumes for both ethylene and polyethylene, our fourth quarter 2020 operating income of $22 million decreased $27 million from the fourth quarter 2019. For the fourth quarter 2020, Olefins operating income decreased $29 million from third quarter 2020, primarily due to lower sales volumes as a result of the hurricanes and was partially offset by higher sales prices and margins for polyethylene. Next, let's turn our attention to the balance sheet and statement of cash flows. We generated $1.3 billion in 2020 in cash flows from operations resulting in cash and cash equivalents of $1.3 billion, with capital expenditures and other investments of $509 million in the business to strengthen the company for the future. We completed the refinancing of the Go Zone and Ike Zone revenue bonds, lowering our debt cost and drove our average interest rate to 3.5%, extending our weighted average debt maturity to 14 years while strengthening our strong investment-grade balance sheet. This solid liquidity position, coupled with long-dated debt maturity schedule, allows us to operate confidently in today's environment. Now, let me address some of your modeling questions. Our effective tax rate for the full year of 2020, excluding the effects of the CARES Act, was approximately 20%, and we expect 2021 to be approximately 22%. For 2021, we expect cash interest expense to be approximately $130 million and our capital expenditures to be between $700 million and $800 million. We are planning for a turnaround of our Petro II ethylene unit to begin in September. The turnaround and associated outage is expected to last approximately 60 days. Last week, extreme winter weather across much of Texas and Louisiana caused widespread power outages and disrupted feedstocks, raw materials and utilities to many plants in our industry, including some of our plants. As a consequence, several of our facilities experienced disruption to their operations. While we are still assessing the impact of the storm, our estimate for loss margins from sales and repair expenses are approximately $120 million. Approximately $100 million will impact our first quarter 2021 results with the remainder falling into the second quarter. With that, I will now turn the call back to Albert to make some closing comments.

Thank you, Steve. As we look ahead, the strength in global demand in polyethylene and PVC that was prevalent in the second half of 2020 is continuing into 2021. We are also seeing continued strength in our downstream building products business, driven by repair and remodeling spending as well as new housing starts. The highly integrated nature of Westlake, which extends from natural gas liquids and salt feedstocks through to consumer building products, combined with our operations sitting on the lower end of the global cost curve, enables us to drive long-term value throughout the business and investment cycles in our industry. Our business fundamentals remain very strong. An improving economy should also have a positive impact on our business into 2021. In our Vinyls segment, the PVC market continues to experience strong demand from our customers, especially in the residential construction, automotive, and appliance industries. The robust residential construction market is also driving strong durable goods demand, benefiting our full product offering in our downstream building products business. In our Olefins business, the chain margins reflect a significant benefit, which has been driven by the rising polyethylene prices we have earlier discussed. We foresee the solid demand for polyethylene that we experienced in the second half of 2020 to continue into 2021. This is driven by continued end-use demand in the essential everyday products, such as consumer products packaging, healthcare, hygiene, and foodservice markets. During the last two years, we expanded the PVC capacity by approximately 800 million pounds, which positions us to meet this growing global PVC demand in 2021. Westlake remains focused on the priorities we value, namely to protect the health and safety of our employees, deliver on our commercial commitments, and strengthen the company in all aspects. We are confident that Westlake is well-positioned to serve the growing needs of our customers while maintaining financial discipline, which combined with the strong fundamentals of our business, enable us to deliver long-term value to our shareholders. Thank you very much for listening to our fourth quarter 2020 earnings call. I will now 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 two hours after the call has ended. We will provide that number again at the end of the call. Joelle, we will now take questions.

[Operator Instructions] Our first question comes from Bob Koort with Goldman Sachs.

Yes. It's actually Mike here sitting in for Bob. I just had a question around the PVC margins. It looks as if the EBITDA margin leads in the fourth quarter, mid-single-digits -- I mean low -- sorry, mid-double digits. I was just wondering, how do you see that playing out for the first half of '21?

Yes. According to IHS report, since June of 2020, the industry is able to increase prices in 2020 by $0.20 a pound in PVC. And in 2021, industry pass-through price increases of $0.04 a pound in January and $0.03 a pound in February. And also price announcements made for March with a price increase of $0.07 a pound. So, this represents not only the growing domestic demand, but also export demand. And actually, export prices since June have increased even higher than domestic demand. And today's export price netback is higher than domestic prices for some customers. So, we see really a global demand strength for PVC.

Okay. Thanks. And just as a follow-up, you mentioned the supply demand outlook is pretty tight right now for PVC. Just in terms of outlook, when do you see that perhaps loosen enough? Does that carry through the first half or perhaps longer into 2021?

Well, so long as interest rates continue to stay low and so long as consumers have money, the housing demand, housing -- 50-year average residential housing construction is about 1.5 million units a year. And since the housing meltdown in 2007, 2008, we -- last year, we were close to climb back to 1.4 million units a year. And this year, we hope to average above 1.5 million. And that's just a 50-year U.S. residential housing construction average for 50 years. So, long as, as I said, the economy is strong and interest is low, I think, the demand will continue to increase.

Our next question comes from Steve Byrne with Bank of America.

...that's approaching the Olefins segment, are you considering splitting that out as a new segment and/or bolting on some more businesses into that building product services business?

Yes. Steve, we've been very pleased with the performance and the strength that you've seen in the overall market. And as I've mentioned, a strong performance by that downstream products -- building products business. And we'll continue to assess the opportunities to give more clarity in that space. But you're right, it has performed very, very well. And as you can see from our prepared remarks, we expect to continue to see it continue well. And we'll continue to assess the ability to give more clarity to everyone about its abilities, but it is certainly an area that we want to continue to grow.

And would you consider bolting on some downstream products that are sourced from polyethylene, such as PECs? The reason I bring it up is PVC pipe in Home Depot sells for about $1 a pound, not too much different than resin. But, those fittings are as much as $10 a pound. And I don't know whether you're capturing that margin or is Home Depot capturing that margin, but it's really healthy.

Yes. Steve, it's not been an area that we've looked at, and our continued area of focus has really been on the downstream vinyls side, as you see us continue to add businesses that have been very constructive to the strength of that business. And we continue to see the ability to add bolt-on opportunities as opportunities present themselves. And we find that an interesting area of focus.

Yes. Steve, I just want to also add that we are one of the few companies in North America that sell pipe and fittings together. So, we have a very well-known brand and our fitting business is doing quite well, as you said.

And any plans to do more debottlenecking in your chlor-alkali business?

Well, we always look at opportunities to grow in all our businesses. And as we mentioned, we had, the last two years, about 800 million pounds of PVC capacity. And with that also, certainly, we need more chlorine and chlor-alkali. And our downstream business seems the business is so strong in construction. We're also looking at debottlenecking capacities to serve the needs of our customers.

And our next question comes from Jeff Zekauskas with JP Morgan.

Thanks very much. You disclosed the trend in chlorine prices through the year or you quoted IHS, and it seems that they ticked up in the fourth quarter. What do you make of that? And is there a trend there?

Certainly, as you know, half of PVC's feedstock is chlorine, the other half is ethylene. So, as PVC demand is strong globally, the draw on chlorine is very high. And hence, chlorine price -- that chlorine also go to other finished products, not necessarily PVC, but in water treatment, in TiO2 and urethane, and many other applications. So chlorine -- because of the high value of chlorine into PVC, chlorine price also increased to reflect the strong demand for the product.

Okay. And your operating cash flow as a percentage of EBITDA was more than 100% than 2020, and maybe it was above 90% in 2019. Historically, it used to be, as a percentage, in the high 60s or 70s or low 80s. Why is the percentage so much higher now, and how do you see that going forward? Do you have a target for operating cash flow as a percentage of EBITDA?

Well, Jeff, it's certainly operating leverage, which has really leveraged that growth in cash flows. And certainly, as we look at opportunities to continue to build on the business, we'll continue to look for opportunities that provide that kind of operating leverage. As Albert noted, we'll look at opportunities across the spectrum. But we don't have a particular target per se, but you can certainly imagine we're focused on opportunities that provide a high degree of operating leverage that allow us to do so with minimal investment in capital.

Should you have a positive -- what's your estimation of the deferred tax benefit in 2021?

The deferred -- I'm sorry.

What's your estimate of the benefit from deferred taxes to your cash flows in 2020?

Yes. I'm not going to quote you a number, but certainly, there'll be some significant benefits as we see moving forward. And certainly, we had, as you may recall, and I made reference to this throughout 2020, we did also have some benefits because of the CARES Act. And because of our large investment in LACC, we also were able to benefit from the net operating loss. So, a variety of opportunities to leverage our tax positions, be they the NOLs or the deferred taxes.

Our next question comes from John McNulty with BMO Capital Markets.

Hi. Good morning. This is Bhavesh Lodaya for John. Regarding the disruptions caused by the Texas freeze, clearly an unprecedented event. So, when you compare that to typical weather events or say, hurricane, could you help us with how different is the process to bring the plant back online? And what is the risk of negative surprises, which could end up kind of extending the downtime for the industry?

Well, hurricanes sometimes cause more damage to equipment and buildings than the freeze. Freeze usually impacts instrumentation boiler that can be more readily fixed. The risk is when plants go down, sometimes with a hard crash of a hurricane, you know it's coming, you prepare, you shut down in an orderly fashion. But the freeze sometimes catches you off guard, your boiler gets tripped and you're out of steam and the plants crash down. Some of those plants may suffer equipment damage from the hard crash. And so, you only know more about it when you restart the plant to find out some things are not working properly. That's the risk of unknowns out there.

Correct. And then, your estimate for the $120 million hit from lost sales, does that assume prices for the commodity stay at current levels? And if so, roughly how much of that will be offset if the industry gets the nominated $0.14 price side over the next couple of months?

Yes. And so, it does contemplate the current price environment that we're in, and it also includes not only lost margin on sales but also some repair costs as well. And so, we'll just have to see if we're successful in some of the price nominations we made for February and for March, and how that sustains itself through the course of the rest of the quarter. You can see that a big portion of this will impact the first quarter. We said $100 million for an impact on the first quarter, and the rest of it will impact Q2.

Our next question comes from David Begleiter with Deutsche Bank.

Just on polyethylene, it looks like February will likely go through or is going through on the $0.07. How are you thinking about the March increase and the prospects of that increase?

Well, several of the polyethylene producers announced the $0.07 price increase with the tightness, but not all the producers have announced price increases. So, time will tell whether that $0.07 will be pushed through. But, the issue now with all the freezes, 100% of Texas as of yesterday, 100% of Texas ethylene plants are offline and 75% of total U.S. ethylene plants are offline. So, the availability of ethylene as well as mentioned earlier, the risk of restarting may impact availability and prices of ethylene, which will impact prices of polyethylene as well. So, we don't know yet to what extent the ethylene shutdown will impact prices of polyethylene going forward.

Very good. And just on the $100 million forecast for the weather impact in Q1, how many weeks of production lost does that assume, and how much production does that assume as well?

So, David, we expect that we'll have those operations up here over the course of the next several weeks. I'm not going to quote a number of pounds, but over the next several weeks, we expect to have ourselves more fully restored.

And our next question comes from Mike Leithead with Barclays.

I guess, I did want to follow-up on that last point about restarting. And I just want to get a better sense of maybe where you are on the restart. Is it largely just on right now Westlake restarting its facilities, or are you still kind of waiting either for suppliers or logistics? Are there any kind of gating items that are preventing you from starting up at this point?

Yes. I think, depending on the plants and locations, some plants are running. We have not declared force majeure for polyethylene as some other industry companies have. And just depending on location, the sites and how much inventory you have to serve your customers.

Got it. Okay. And I did want to change topic. I wanted to ask on caustic soda, it feels like obviously that's been weak for a couple of quarters now. I want to get a sense if you feel like we're at or near bottom here or just what your outlook for caustic soda would be over the next, say, couple of quarters here?

That's a good question. Usually, PVC, because of its vast connection with the construction industry with low-interest rates. So, PVC usually is a leading economic indicator on the cycle coming back. And usually, caustic is either concurrent or a little bit lagging indicator. So, as the economy improves, caustic demand will increase more, and hence the price will improve. And looking at both domestic and international prices, we see that the caustic prices starting to move up from the bottom, we saw early end of last year, early this year. So, we believe that we're seeing the bottom of caustic prices.

Next question comes from Mike Sison with Wells Fargo.

When I take a look at the Vinyls EBITDA margin in the fourth quarter, 21%, you’re pretty close to what you guys were seeing in '17, '18. If you think about the price increases that IHS is forecasting and then kind of the margins for the year, should the rest of '21 be kind of in that level or higher, excluding the impact of the first quarter winter storm you already hit?

Well, certainly, we'd like to see those margins at those levels. As you know, the vinyl business was impacted pretty severely with the COVID-19 downturn earlier in 2020. And we mentioned also that the integrated nature into building products, and with the strength in building products, that has really helped also improve Vinyls margin. The weakness, as Steve mentioned in his remarks, is that our improvements in earnings are offset by the weakness in caustic. And as I mentioned earlier, we believe we hit the bottom in caustic and hope the question then is how fast, how soon caustic will improve. So, that will be another tailwind in helping the business recovery.

Okay. And then, one just quick follow-up on vinyls. Once your facilities are up and running, given what you've mentioned in terms of demand, do you think you'll be running effectively full out for the remainder of the year?

Yes, we were running full out before, until we had problems. But, everything we see today that not only U.S. demand is strong, but global demand is strong. As I said, the export price is higher than domestic prices. So, as long as the COVID-19 impact has lessened, hopefully, for the world economy. And with the increased vaccination rates around the world, we believe the economy should improve. And with the government stimulus package, it would help construction infrastructure and definitely will help the PVC business and related businesses.

Our next question comes from Frank Mitsch with Fermium Research.

I want to follow up on the freeze, your impact, $100 million in Q1, $20 million in Q2. How are you thinking about that between the two segments? And, the $20 million negative for 2Q, I am assuming that you guys are fully back up and running by April 1. Is that not a right assumption? Is it lost sales from not being able to build inventory? If you could just explain a little bit more about how you came up with those numbers.

Yes. Frank, I would expect it will be up well before that. And from an impact perspective, I would say that the impact is on a vinyls basis. It's about 80% of that impact is in the Vinyls segment, and 20% of that is in the Olefins segment, both for Q1 and for Q2 in terms of how they split out between the two segments for the $100 million and for the remaining $20 million in the second quarter.

And the $20 million for the second quarter, is that an ability to build inventory? How do we think about that?

Yes. And so, the -- as I say, the second quarter -- let me just clarify that when I said 80% Vinyls, that's in total. The impact in the second quarter will be all Vinyls. It's really the flow-through of PVC resin and further downstream into our vinyls building products businesses.

Our next question comes from Arun Viswanathan with RBC Capital Markets.

I guess, I just wanted to get your thoughts on the disruptions that are going down in Texas. How do you see that kind of impacting the industry longer term? I know that operations are now starting back up. But, you see inventories kind of where they're already at low levels. And so, this is going to exacerbate the production a little bit more, or maybe you can just talk to your thoughts on the evolution here in the next couple of months?

Yes. With most of the plants down in Texas, inventory will be coming down and produced inventory is quite low now. So, when the plants come back, they have to replenish inventory first, and so they will curtail sales, whether it's export or domestic, in order to build inventory back to a reasonable level.

And then, as far as feedstocks go, do you see any pressure in the next, say, 6 to 12 months from potentially higher ethane costs, or do you see ethane remaining relatively flexible?

Well, it depends on who you look at. If you look at IHS forecast for ethane, they are looking at 2021 in the mid to high $0.20 per gallon. But then, if you look at the future prices, in 2021 it is more of a low to mid $0.20 per gallon range or mid $0.20 per gallon range. So, they do not forecast a ramp-up in ethane prices.

And then, if I can just ask one more follow-up. In the Vinyls business, one of your main competitors has changed strategies a little bit, and it's potentially moving off index for caustic pricing. Has that had any effect, I guess, on overall industry dynamics and the way that you think about maximizing value for your Vinyls business? Thanks.

Yes. The caustic business is very competitive. There are quite a few large and small producers. And because of the big demand for chlorine, every pound of chlorine produced also produces 1.1 pounds of caustic. So, the demand is -- when demand for chlorine is strong, we produce a lot of caustic. The economy is not picking up pace for caustic, PVC, or chlorine, then you have excess caustic, which shows the weakness in price. As I mentioned earlier, as the economy improves, that weakness will be absorbed. So, it's a very competitive business.

Our next question comes from Hassan Ahmed with Alembic Global.

A question around polyethylene sort of supply-demand fundamentals and pricing. I mean, obviously, we were all pleasantly surprised by the strength of utilization rates in 2020. They continue to be strong. And there are obviously a variety of moving parts there, the sort of strength from the nondurable side of things. And then oil obviously presently surprised. And now, you have maybe some impact from the weather-related outages, and we're going into a pretty heavy turnaround season as well. I mean, my question is, how are you guys, as it pertains to 2021, what are you guys seeing in terms of the sustainability of this tightness in terms of the sustainability of these high levels of pricing? I mean -- and I guess, the question really is that would it be a tale of two halves where we see extreme strength in H1 and maybe we see potential cracks in pricing in the second half of the year as a lot of these turnarounds are behind us.

Well, as one thing we do know is there are a lot of things we don't know. We didn't predict the freeze; we didn't predict the two hurricanes in a span of two months. So, a lot of things could happen. But, I think the fundamentals of supply-demand, global supply-demand. Certainly, there's a fair amount of polyethylene capacity added globally. But the pandemic, with this great demand for internet sales and packaging and with PPEs and also with the increased demand for solar panels. So, a lot of the polyethylene LDPE plants shift to making EVAs for solar panels. So then the rest of the packaging LDPE demand supply is being reduced. All these changing dynamics are impacting the demand side. On the PVC side, very little capacity added around the world the last few years. We have -- as mentioned, we have added about 800 million pounds of capacity the last two years. And now, some of our competitors are announcing new capacity expansions and the global demand increase. And yet globally, very few capacity in PVC has been added or announced. So if you see the global demand dynamics and then with the supply, there you can conclude where prices will go. Now, month-to-month, sure, it will gyrate, depending on inventory, supply-demand, and many other things; it will go up and down. But I think when people are spending billions of dollars building new plants, it shows confidence that our business in the long term should be better.

Fair enough, Albert. Very helpful. And as a follow-up, on M&A, how are you guys thinking about M&A in this market? I mean, obviously, there are some chlorovinyls assets up for sale. A, what are your broader thoughts about M&A? And alongside that, how are you thinking about prioritizing between the two segments? I mean, would you have the preference if you were to indulge in M&A on the chlorovinyl side over olefins or vice versa?

So, Hassan, as you well know, we've grown the business both organically and through acquisition over time. And we'll continue to look at opportunities on the acquisition side. We look at opportunities obviously directly in our space, but we'll also look at adjacencies. You've seen us continue to expand in our downstream building products businesses. And we'll look even beyond those that make sense to us. And so, we'll look at those, but it's always about finding the right fit, the right synergistic opportunity is the kind of thing that we're always looking for.

Our next question comes from Jonas Oxgaard with Bernstein.

Thank you. Looking at your downstream PVC business, I was kind of wondering how much of the benefit you got was driven by margin enhancement from the outages -- or from the shortages, I should say, and how much was volume gain from the economy restarting, et cetera? So, I was hoping you could help me deconvolute that business a little bit.

Certainly. As we mentioned earlier, early part of last year when the pandemic hit, many of the municipalities shut down construction. So, we had to shut down production of our products. So, both the Vinyl business and some of the plants were impacted as well as building products. But, as soon as the municipality opens up, and as you know, most of the constructions are outdoors, then the demand came back. And as well, there is a movement from urban to suburban areas in constructions. So, single-family homes construction demand starts to increase and also repair and remodeling, people at home with money that are spending on traveling or vacationing, and they're spending money in their home. So, building and construction products demand has increased. Our building products, we were practically sold out all the way when the demand started to improve. And as Steve mentioned, fourth quarter, typically seasonally, because of the cold temperature and snow, then the sales into construction, especially outdoors, slow down as normal. And we built up inventory during that time period, ready for the spring. And now spring back is coming back and the demand is very strong.

Okay. Well, I guess, the question though is how much of the boom in Q4 was temporary versus say …

The boom actually continues, starting from let's say May or June, just keep on -- every month is improving. Actually, Q4 demand sales in the building products slowed down because of the seasonal weather issues typically for the construction business. And then, the first quarter, second quarter is a strong season for the building business. But you're saying on a long-term basis, as mentioned, the U.S. residential construction, 50-year average, about 1.5 million units. We went from the high of 2007 or 2006 with the housing meltdown in 2008, it dropped from 2.3 million units or so to 400,000. And from 400,000, we climbed back to about 1.4 million units average last year in 2020. And the 50-year U.S. residential construction average, 50-year average is 1.5 million units. So, we just got back close to the 50-year average. And if you believe that with low-interest rates and demand continuing to be strong, the population in the U.S. certainly has increased over the 50-year average, then the long-term trend, the demand for construction will continue to increase.

Okay. Thank you. I was also wondering, the losses that you got from the hurricane and the projected losses here from the deep freeze are quite large in relation to your overall EBITDA. Will any of this be recouped by insurance?

Well, some of the -- certainly, some of the -- our damages can be recouped. But, I'll let Steve answer that.

Yes. Thank you for the question. Yes, we certainly do have insurance. And so certainly, as we work through those claims, we'll be able to recover a majority of that damage claim from the hurricanes. And so, certainly, those are the big issues on the freeze. We'll still be assessing that and see if there is an opportunity for insurance claims on the freeze.

Okay. Is it like a magnitude of how much you expect to recoup and then timing on that?

On the freeze, it's obviously lost margin. So, it's very little property damage. On the hurricanes, it was more property damage than it was necessarily lost margin. So, different kinds of claim provisions here. So, on the freeze, I expect less recovery; on the hurricanes, I do expect substantial recovery.

At this time, the Q&A session has now ended. Are there any closing remarks?

Yes. Thank you, Joelle. The management team needs to switch over to the Westlake Chemical Partners LP Call. So, we encourage anyone, who has not had time to ask a question on this call, to call us afterwards, and we'll be happy to address their questions. Thank you again for your time. And we hope you'll join us again for our next conference call to discuss our first quarter 2021 results.
