ITEM 1. BUSINESS
Item 1. Business
General
We are a vertically integrated global manufacturer and marketer of performance and essential materials and housing and infrastructure products that enhances the lives of people every day. Our products include some of the most widely used materials in the world, which are fundamental to many diverse consumer and industrial markets, including residential construction, flexible and rigid packaging, automotive products, healthcare products, water treatment, coatings as well as other durable and non-durable goods. We have historically operated in two principal operating segments, Vinyls and Olefins. As a result of recent acquisitions, in the fourth quarter of 2021, we reorganized our business into two principal operating segments, Performance and Essential Materials and Housing and Infrastructure Products. Performance and Essential Materials includes Westlake North American Vinyls, Westlake North American Chlor-alkali & Derivatives, Westlake European & Asian Chlorovinyls, Westlake Olefins and Westlake Polyethylene. Housing and Infrastructure Products includes Westlake Royal Building Products, Westlake Pipe & Fittings, Westlake Global Compounds and Westlake Dimex. The change has been retrospectively reflected in the periods presented in this Form 10-K. We are highly integrated along our materials chain with significant downstream integration from ethylene and chlor-alkali (chlorine and caustic soda) into vinyls, polyethylene and styrene monomer. We also have substantial downstream integration from PVC into our building products, PVC pipes and fittings and PVC compounds in our Housing and Infrastructure Products segment.
We began operations in 1986. Since 1986, we have grown rapidly into an integrated global producer of chemicals and building products. We achieved this growth by acquiring existing plants or constructing new plants and completing numerous capacity or production line expansions. We regularly consider acquisitions and other internal and external growth opportunities that would be consistent with, or complementary to, our overall business strategy.
In 2014, we formed Westlake Chemical Partners LP ("Westlake Partners") to operate, acquire and develop ethylene production facilities and related assets. Also in 2014, Westlake Partners completed an initial public offering of common units (the "Westlake Partners IPO"). As of February 16, 2022, Westlake Partners' assets consisted of a 22.8% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), as well as the general partner interest in OpCo. Prior to the Westlake Partners IPO, OpCo's assets were wholly-owned by us. OpCo's assets include two ethylene production facilities at our olefins facility in Lake Charles, one ethylene production facility at our Calvert City site and a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu, Texas to the Longview, Texas site, which includes our Longview polyethylene production facility. We retain a 77.2% limited partner interest in OpCo, a 40.1% limited partner interest in Westlake Partners (consisting of 14,122,230 common units), a general partner interest in Westlake Partners and incentive distribution rights. The operations of Westlake Partners are consolidated in our financial statements. We are party to certain agreements with Westlake Partners and OpCo whereby, among other things, OpCo sells us 95% of the ethylene it produces on a cost-plus basis that is expected to generate a fixed margin per pound of $0.10. We use this ethylene in the production processes of our Performance and Essential Materials segment. For more information, see "-Performance and Essential Materials Business" below.
On January 2, 2019, we completed the acquisition of NAKANTM, a global compounding solutions business. NAKAN's products are used in a wide-variety of applications, including in the automotive, building and construction, and medical industries. With this acquisition, our PVC compounding business now has facilities worldwide in China, France, Germany, Italy, Japan, Mexico, Spain, the United States and Vietnam, as well as a world-class research facility in France and several application laboratories.
On November 12, 2019, we completed the acquisition of an additional 34.8% of the membership interests in LACC, LLC ("LACC") from Lotte Chemical USA Corporation, a subsidiary of Lotte Chemical Corporation ("Lotte"), for approximately $817 million (the "Transaction"). Prior to the Transaction, we owned approximately 12% of the membership interests in LACC. As of December 31, 2021, we owned an aggregate 46.8% membership interest in LACC. The LACC ethylene plant has 2.2 billion pounds per year of ethylene production capacity and is adjacent to our chlor-alkali facility in Lake Charles. During the third quarter of 2019, the LACC ethylene plant began commercial operations. As a result of the Transaction, we receive our proportionate share of LACC's ethylene production on a cash-cost basis, which is expected to benefit our integrated downstream operations.
In January 2022, we notified Lotte of our exercise of an option to acquire an additional 3.2% membership interest in LACC from Lotte for approximately $90 million.
On June 20, 2021, we, through one of our wholly-owned subsidiaries, entered into an Equity Purchase Agreement (the "Boral Purchase Agreement") by and among Boral Building Products Inc., a Michigan corporation, Boral Stone Products LLC, a Delaware limited liability company, Boral Lifetile Inc., a California corporation, Boral Windows LLC, a Utah limited liability company, Boral Industries Inc., a California corporation ("Boral Industries"), and, solely for the limited purposes set forth therein, we and Boral Limited, an Australian corporation ("Boral"). Pursuant to the terms of the Boral Purchase Agreement, we agreed to acquire from Boral Industries all of the issued and outstanding equity interests of certain subsidiaries of Boral Industries engaged in Boral's North American building products businesses in roofing, siding, trim and shutters, decorative stone and windows (the "Boral Target Companies"). On October 1, 2021, we completed the acquisition of the Boral Target Companies (the "Boral Acquisition"). The total closing purchase consideration was $2,132 million subject to working capital post-closing adjustments as well as a potential earn-out payment of up to $65 million if the windows division of Boral Target Companies generates EBITDA in excess of a specified target in its fiscal year ending June 30, 2024. The assets acquired and liabilities assumed and the results of operations of this business are included in the Housing and Infrastructure Products segment.
On August 19, 2021, we completed the acquisition of, and acquired all of the equity interests in LASCO Fittings, Inc. ("LASCO"), a manufacturer of injected-molded PVC fittings that serve the plumbing, pool and spa, industrial, irrigation and retail markets in the United States from Aalberts U.S. Holding Corp. and Aalberts N.V. (the "LASCO Acquisition"). The total closing purchase consideration was $277 million. The assets acquired and liabilities assumed and the results of operations of LASCO are included in the Housing and Infrastructure Products segment.
On September 10, 2021, we completed the acquisition of, and acquired all of the equity interests in, DX Acquisition Corp. ("Dimex"), a producer of various consumer products made from post-industrial-recycled polyvinyl chloride, polyethylene and thermoplastic elastomer materials, including, landscape edging; industrial, home and office matting; marine dock edging; and masonry joint controls (the "Dimex Acquisition" and, together with the Boral Acquisition and the LASCO Acquisition, the "2021 Acquisitions"). The total closing purchase consideration was $172 million. The assets acquired and liabilities assumed and the results of operations of Dimex are included in the Housing and Infrastructure Products segment.
On February 1, 2022, we completed the acquisition of the global epoxy business of Hexion Inc. ("Hexion epoxy"). The total closing purchase consideration was approximately $1,200 million, subject to post-closing adjustments (the "Hexion Acquisition" and, together with the 2021 Acquisitions, the "Acquisitions"). The assets acquired and liabilities assumed and the results of operations of Hexion epoxy will be included in the Performance and Essential Materials segment. This acquisition represents a significant strategic expansion of Westlake's Performance and Essential Materials businesses into additional high-growth, innovative and sustainable-oriented applications - such as wind turbine blades and light-weight automotive structural components. Because epoxies are produced from chlorine and caustic soda, the transaction also provides vertical integration with Westlake's global chlor-alkali businesses.
Performance and Essential Materials Business

Ethylene. Ethylene is the world's most widely used petrochemical in terms of volume. It is the key building block used to produce a large number of higher value-added chemicals including polyethylene, EDC, VCM and styrene. OpCo has the capacity to produce approximately 3.0 billion pounds of ethylene per year at our Lake Charles site, and we have the capability to consume all of OpCo's production that we purchase at Lake Charles to produce EDC, VCM, polyethylene and styrene monomer. In addition, we (through OpCo) produce ethylene co-products including chemical grade propylene, crude butadiene, pyrolysis gasoline and hydrogen. We (through OpCo) sell our entire output of these co-products to external customers. The ethylene from OpCo's facility in Calvert City and LACC is utilized to produce VCM at our facilities. We obtain the remainder of the ethylene we need for our business from third party purchases. The use of ethane feedstock by our ethylene plants enables us to enhance our low-cost materials chain integration.
Chlorine and Caustic Soda. We are the second-largest chlor-alkali producer in the world. We combine salt and electricity to produce chlorine and caustic soda, commonly referred to as chlor-alkali, at our Lake Charles, Plaquemine, Natrium, Calvert City, Geismar, Beauharnois, Longview (WA), Gendorf, Knapsack and Kaohsiung facilities. We use our chlorine production in our VCM and chlorinated derivative products plants. We currently have the capacity to supply all of our chlorine requirements internally. Any remaining chlorine is sold into the merchant chlorine market. Our caustic soda is sold to external customers who use it for, among other things, the production of pulp and paper, organic and inorganic chemicals and alumina.
VCM. VCM is used to produce PVC, solvents and PVC-related products. We use ethylene and chlorine to produce EDC, which is used in turn, to produce VCM. We have the capacity to produce approximately 6.3 billion pounds and 1.6 billion pounds of VCM per year at our North American and European facilities, respectively. The majority of our VCM is used internally in our PVC operations. VCM and EDC not used internally are sold externally.
PVC. PVC, the world's third most widely used plastic, is an attractive alternative to traditional materials such as glass, metal, wood, concrete and other plastic materials because of its versatility, durability and cost-competitiveness. PVC is produced from VCM, which is, in turn, made from chlorine and ethylene.
We are the second-largest PVC producer in the world. With the completion of our previously announced expansion projects at our Geismar and Burghausen plants in 2019, we have the capacity to produce approximately 6.8 billion pounds and 1.0 billion pounds of commodity and specialty PVC per year, respectively, at our various facilities globally. We use some of our PVC internally in the production of our building products, PVC pipes and fittings and PVC compounds in the Housing and Infrastructure Products segment. The remainder of our PVC is sold to downstream fabricators and the international markets.
Polyethylene. Polyethylene, the world's most widely consumed polymer, is used in the manufacture of a wide variety of film, coatings and molded product applications primarily used in packaging. Polyethylene is generally classified as either LDPE, LLDPE or high-density polyethylene ("HDPE"). The density correlates to the relative stiffness of the end-use products. The difference between LDPE and LLDPE is molecular, and products produced from LLDPE, in general, have higher strength properties than products produced from LDPE. LDPE exhibits better clarity and other physical properties and is used in end products such as bread bags, food wraps, milk carton coatings and food packaging. LLDPE is used for higher film strength applications such as stretch film and heavy-duty sacks. HDPE is used to manufacture products such as grocery, merchandise and trash bags, rigid plastic containers, plastic closures and pipe.
We are a leading producer of LDPE by capacity in North America and predominantly use the autoclave technology (versus tubular technology), which is capable of producing higher-margin specialty polyethylene products. In 2021, our annual capacity of approximately 1.5 billion pounds of LDPE was available in numerous formulations to meet the needs of our diverse customer base. We also have the capacity to produce approximately 1.1 billion pounds of LLDPE per year in various formulations. We produce LDPE and LLDPE at both the Lake Charles and Longview (TX) facilities. Our Lake Charles and Longview facilities also have the capability to produce HDPE. We sell polyethylene to external customers as a final product in pellet form.
Chlorinated Derivative Materials. Our chlorinated derivative products include ethyl chloride, perchloroethylene, trichloroethylene, tri-ethane® solvents, VersaTRANS® solvents, calcium hypochlorite, hydrochloric acid ("HCL") and pelletized caustic soda ("PELS"). We have the capacity to produce approximately 2.3 billion pounds of chlorinated derivative products per year, primarily at our Lake Charles, Natrium, Beauharnois and Longview (WA) facilities. The majority of our chlorinated derivative products are sold to external customers who use these products for, among other things, refrigerants, water treatment applications, chemicals and pharmaceutical production, food processing, steel pickling, solvent and cleaning chemicals and natural gas and oil production.
Styrene. Styrene is used to produce derivatives such as polystyrene, acrylonitrile butadiene styrene, unsaturated polyester and synthetic rubber. These derivatives are used in a number of applications including consumer disposables, food packaging, housewares, paints and coatings, building materials, tires and toys. We produce styrene at our Lake Charles plant, where we have the capacity to produce approximately 570 million pounds of styrene per year, all of which is sold to external customers.
Electricity. Our Lake Charles, Plaquemine and Natrium cogeneration assets have the capacity to generate electricity of approximately 420, 240 and 100 megawatts, respectively, per year. Our North American joint ventures include a 50% interest in RS Cogen L.L.C. ("RS Cogen") that generates electricity, of which our share is approximately 212 megawatts.
Feedstocks
We are highly integrated along our materials production chain. We (through OpCo) produce most of the ethylene required to produce our polyethylene and styrene. Ethylene can be produced from either petroleum liquid feedstocks, such as naphtha, condensates and gas oils, or from natural gas liquid feedstocks, such as ethane, propane and butane. Both of OpCo's Lake Charles ethylene plants use ethane as the primary feedstock. Pursuant to a feedstock supply agreement between us and OpCo, OpCo receives ethane feedstock at our Lake Charles site through several pipelines from a variety of suppliers in Texas and Louisiana. We own a 50% interest in a 104-mile natural gas liquids pipeline from Mont Belvieu to our Lake Charles site. OpCo owns a 200-mile ethylene pipeline that runs from Mont Belvieu to our Longview (TX) site. Additionally, through OpCo, we produce most of the ethylene required at our Calvert City facility utilizing ethane feedstock. The LACC ethylene facility is located adjacent to our chlor-alkali facility in Lake Charles and has an ethylene production capacity of 2.2 billion pounds per year. During the third quarter of 2019, the LACC ethylene plant began its commercial operations. At December 31, 2021, we, through one of our subsidiaries, owned 46.8% of the membership interests in LACC. We receive our proportionate share in ethylene production on a cash-cost basis and primarily use it to produce VCM. In addition to ethylene supplied by OpCo and LACC, we also acquire ethylene from third parties in order to supply a portion of our ethylene requirements. In Germany, we have access to, and partially own, an ethylene pipeline.
We acquire butene and hexene to manufacture polyethylene and benzene to manufacture styrene. We receive butene and hexene at the Lake Charles site and hexene at the Longview (TX) site via rail car from several suppliers. We receive benzene via barges, ships and pipeline pursuant to short-term arrangements. We purchase butene and hexene pursuant to multi-year contracts.
The salt requirements for several of our larger chlor-alkali plants are supplied internally from salt domes we either own or lease and the salt is transported by pipelines we own. We purchase the salt required for our other chlor-alkali plants pursuant to long-term contracts. Electricity and steam for one of our Lake Charles facilities are produced by both on-site cogeneration units and through a toll arrangement with RS Cogen, a joint venture in which we own a 50% interest. RS Cogen operates a process steam, natural gas-fired cogeneration facility adjacent to the site. Electricity and steam for the Plaquemine facility are supplied internally by our on-site cogeneration unit. A portion of our Natrium facility's electricity requirements is produced by our on-site generation unit, and the remainder is purchased. We purchase electricity for our remaining facilities under long-term contracts. We purchase VCM for our Asian PVC plant on a contract and spot basis.
Sustainability
As a leading global producer of plastics, we understand the importance of reducing the environmental impact of our feedstocks, production and usage, and developing innovations, together with our customers, to meet their objectives while also reducing their environmental impact. To further these objectives, we have launched environmentally friendly product innovations. In 2021, we introduced our GreenVinTM Caustic Soda and GreenVinTM PVC products in Germany. Due to the extensive global use of PVC and caustic soda, these developments present an opportunity for Westlake customers to enhance the sustainable qualities of their products.
Caustic Soda is an essential ingredient for the production of many materials, ranging from paper, detergents, construction materials, food packaging, pharmaceuticals and water treatments products. The plants of our German subsidiary Vinnolit, have been producing caustic soda in chlor-alkali electrolysis exclusively with the energy-saving and environmentally friendly membrane process since 2009. Since the central process step is electrified, power from renewable sources can be used to save CO2 emissions by displacing fossil fuels. By using such renewable power sources, the CO2 footprint of GreenVinTM Caustic Soda is reduced by approximately 30% compared to conventional Vinnolit caustic soda.
PVC is an essential ingredient in making some of the world's most prevalent items, including residential siding, pipe and fittings for various water, sewer and industrial applications, PVC profiles for windows, doors, fence, resin paste and artificial leather among others and decking along with films for various inflatables, wallcovering, tapes and roofing applications. The CO2 footprint of Vinnolit's new lower-carbon PVC, which was introduced to the market under the brand name GreenVinTM and is produced with power from renewable sources, is reduced by approximately 25% compared to conventional Vinnolit PVC.
Marketing, Sales and Distribution
We have a dedicated sales force for our business, organized by product line and region that sells our products directly to our customers. In addition, we rely on distributors to market products to smaller customers. Our polyethylene customers are some of the nation's largest producers of film and flexible packaging. We and OpCo sell ethylene and ethylene co-products to external customers. OpCo's primary ethylene co-products are chemical grade propylene, crude butadiene, pyrolysis gasoline and hydrogen. We have storage agreements and exchange agreements that provide us and OpCo with access to customers who are not directly connected to the pipeline system that we own. OpCo ships crude butadiene and pyrolysis gasoline by rail or truck. Additionally, we transport our polyethylene and styrene by rail or truck. Further, styrene can be transported by barge or ship.
We use some of our PVC internally in the production of our building products, pipes and fittings and PVC compounds in the Housing and Infrastructure Products segment. The remainder of our PVC is sold to downstream fabricators and the international markets. We have the capacity to use a majority of our chlorine internally to produce VCM and EDC, most of which, in turn, is used to produce PVC. We also use our chlorine internally to produce chlorinated derivative products. We sell the remainder of our chlorine and substantially all of our caustic soda production to external customers. The majority of our products are shipped from production facilities directly to the customer via pipeline, truck, rail, barge and/or ship. The remaining products are shipped from production facilities to third party chemical terminals and warehouses until being sold to customers.
No single customer accounted for 10% or more of net sales for the Performance and Essential Materials segment in 2021.

We have typically experienced moderately higher levels of sales of our residential products in the first half of the year due to inventory restocking and improved weather for construction. Our sales are affected by the individual decisions of distributors and dealers on the levels of inventory they carry, their views on product demand, their financial condition and the manner in which they choose to manage inventory risk. Our sales are also generally impacted by the number of days in a quarter or a year that contractors and other professionals are able to install our products. This can vary dramatically based on, among other things, weather events such as rain, snow and extreme temperatures. We have generally experienced lower levels of sales of our housing products in the fourth quarter due to adverse weather conditions in certain markets, which typically reduces the construction and renovation activity during the winter season.
Environmental
As is common in our industry, we are subject to environmental laws and regulations related to the use, storage, handling, generation, transportation, emission, discharge, disposal and remediation of, and exposure to, hazardous and non-hazardous substances and wastes in all of the countries in which we do business. National, state or provincial and local standards regulating air, water and land quality affect substantially all of our manufacturing locations around the world. Compliance with such laws and regulations has required and will continue to require capital expenditures and increase operating costs.
It is our policy to comply with all environmental, health and safety requirements and to provide safe and environmentally sound workplaces for our employees. In some cases, compliance can be achieved only by incurring capital expenditures. In 2021, we made capital expenditures of $33 million related to environmental compliance. We estimate that we will make capital expenditures of approximately $56 million in 2022 and $83 million in 2023, respectively, related to environmental compliance. The expected 2022 and 2023 capital expenditures are relatively higher than the amounts we have spent related to environmental compliance in recent years in large part due to capital expenditures related to previously existing and new Environmental Protection Agency (the "EPA") regulations and corrective actions required by the EPA to resolve the flare enforcement matter discussed below. The remainder of the 2022 and 2023 estimated expenditures are related to equipment replacement and upgrades. We anticipate that stringent environmental regulations will continue to be imposed on us and the industry in general. Although we cannot predict with certainty future expenditures, management believes that our current spending trends will continue.
From time to time, we receive notices or inquiries from government entities regarding alleged violations of environmental laws and regulations pertaining to, among other things, the disposal, emission and storage of chemical substances, including hazardous wastes. Pursuant to Item 103 of the SEC's Regulation S-K, the following environmental matters involve a governmental authority as a party to the proceedings and potential monetary sanctions that we believe could exceed $1 million (which is less than one percent of our current assets on a consolidated basis as of December 31, 2021):
•For several years, the EPA has been conducting an enforcement initiative against petroleum refineries and petrochemical plants with respect to emissions from flares. On April 21, 2014, we received a Clean Air Act Section 114 Information Request from the EPA which sought information regarding flares at the Calvert City facility and certain Lake Charles facilities. The EPA has informed us that the information provided leads the EPA to believe that some of the flares are out of compliance with applicable standards. The EPA has indicated that it is seeking a consent decree that would obligate us to take corrective actions relating to the alleged noncompliance. We believe the resolution of these matters may require the payment of a monetary sanction in excess of $1 million.
We do not believe that the resolution of these flare matters will have a material adverse effect on our financial condition, results of operations or cash flows.
Also see our discussion of our environmental matters contained in Item 1A, "Risk Factors" below, Item 3, "Legal Proceedings" below and Note 22 to our consolidated financial statements included in Item 8 of this Form 10-K.
Human Capital
Westlake is committed to acting in a safe, ethical, environmentally, and socially responsible manner. We have been a public company for 17 years, but we still think of our employees as members of our extended family. We value the integrity, creativity, dedication and diversity of ideas that our employees bring to work every day.
Diversity, Equity and Inclusion (DEI)
As a global company, we recognize the diversity of our employees, customers and communities, and believe in creating an inclusive and equitable environment that represents a broad spectrum of backgrounds and cultures. A significant portion of our management team and our Board of Directors comes from diverse backgrounds, and we are focused on hiring and retaining diverse and talented employees. Our Board of Directors has charged the Compensation Committee with oversight responsibility of the Company's DEI efforts.
As an Asian American and Pacific Islander ("AAPI")-controlled business, we feel a special commitment to ensuring that Westlake continues to offer opportunities for employees of all backgrounds and experiences. As of December 31, 2021, approximately 37% of our employees in the United States and Canada self-identified as Black, indigenous, Hispanic, or AAPI. Although we do not collect demographic data in our European and Asian workforces, we know that we are a diverse, multinational company.
Training and Professional Development
As part of our retention and promotion efforts, we invest in internal leadership development. Westlake regularly provides its employees with training opportunities, including safety training, technical courses, compliance with company policies, business and professional development training, and professional growth classes. In conjunction with technical training, we believe that the non-technical training helps to create well-rounded, and highly-driven, employees. In addition, we periodically conduct employee surveys to gauge employee engagement and identify areas for additional focus.
Headcount
As of December 31, 2021, we had approximately 14,550 employees in the following areas:
Category Number
Performance and Essential Materials segment 5,400
Housing and Infrastructure Products segment 8,760
Corporate and other 390
Our employees are distributed across 16 countries. As of December 31, 2021, approximately 72% were employed in the United States. Approximately 24.7% of our employees are represented by labor unions, and all of these union employees are working under collective bargaining agreements that expire at various times through 2026. We have multiple collective bargaining agreements in Europe, North America and Asia, covering different groups of our work force. There were no strikes, lockouts or work stoppages in 2021, and we believe that our relationship with our employees and unions is open and positive.
Attracting, developing and retaining talented people is crucial to executing our strategy. Our ability to recruit and retain such talent depends on a number of factors, including compensation and benefits, career opportunities and work environment. We provide our employees with competitive compensation packages, development programs that enable continued learning and growth, and comprehensive and competitive benefit packages worldwide. Our compensation and benefits arrangements generally are tailored to local markets of operation.
Health and Safety
The health and safety of our employees and our operations is our highest priority. Our health and safety programs are designed around global standards with appropriate variations addressing the multiple jurisdictions and regulations, specific hazards and unique working environments of our manufacturing, research and development, and administrative office locations. We require each of our locations to perform regular safety audits to ensure proper safety policies, program procedures, analyses and training are in place.
Our focus on safety starts at the top with our Board of Directors. Safety is a key performance indicator that is reported on and discussed at every Board meeting. Our Health, Safety and Environment ("HSE") team plays a pivotal role in overseeing all related policy protections, risk identification and other aspects of our business.
Several of our U.S. manufacturing sites have been recognized by the U.S. Occupational Safety & Health Administration's ("OSHA") Voluntary Protection Program ("VPP") for their low injury rates, employee engagement and safety programs. All of our chemical sites in Germany satisfy the Deutsche Industrie Norm ISO 45001 certification program, which is comparable to VPP.
With respect to the ongoing COVID-19 pandemic, we have adopted safety guidelines and practices, including safety and health training for existing and new employees, remote working, health screening of employees, contact tracing for reported exposure, enforcing self-isolation after exposure, provisions for mask wearing, modifications to the in-office work environment, social distancing, increased sanitation stations and increased cleaning of offices and workstations.
Intellectual Property and Technology
We rely upon both trademark and service mark protection to protect our brands, and have registered or applied to register many of these on a world-wide basis. We have over 1000 active and pending trademark registrations worldwide for our various business segments. We also rely on a combination of patents and un-patented proprietary know-how and trade secrets to preserve our competitive technology position in the market. We have over 900 issued patents and pending patent applications in the United States and several other countries. While some of our production capacity operates under licenses from third parties, other parts of our production operate under technology that was developed internally. Consequently, we offer our own independently developed technology for licensing when the opportunity makes sense on a commercial basis. Although the Company considers its patents, licenses, trademarks and trade secrets in the aggregate to constitute a valuable asset that provides competitive advantage to us, we do not regard any one of our businesses as being materially dependent upon any single or group of related patents, trademarks, licenses, or trade secrets.

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
Risk Factors Relating to Our Operations
The impact and effects of public health crises, pandemics and epidemics, including the ongoing coronavirus ("COVID-19") pandemic, could materially adversely affect our business, financial condition and results of operations.
Public health crises, pandemics and epidemics, such as the COVID-19 pandemic, could materially adversely affect our business, financial condition and results of operations. The COVID-19 pandemic has resulted in authorities implementing numerous measures to try to contain the disease, such as travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns, among others. There have been widespread adverse impacts on the global economy, many of our facilities and on our employees, customers and suppliers. We have encountered supply chain constraints and disruptions and workforce availability issues as a result of COVID-19 related actions.
Despite the availability of vaccines in all of the jurisdictions in which we operate, the COVID-19 pandemic may continue unabated or worsen, including as a result of the emergence of more infectious strains of the virus or vaccine hesitancy. The perceived risk of infection and health risks associated with COVID-19 has and will continue to alter behaviors of consumers and policies of companies around the world.
We have modified certain business practices (including those related to employee travel, employee work locations and employee work practices) to conform to government restrictions and best practices encouraged by governmental and regulatory authorities. We may take further actions as required by government authorities or that we determine are in the best interests of our employees, customers, partners, and suppliers. However, the inability to operate our facilities or the reduced demand for our products could adversely affect our business. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus, and our ability to perform certain functions could be harmed. The ultimate extent of the impact of COVID-19 on our business, financial condition and results of operations will depend largely on future developments, including the duration and spread of COVID-19 within the United States and the parts of the world in which we operate, the impact of governmental actions designed to prevent the spread of COVID-19 and the development, availability, timely distribution and acceptance of effective treatments and vaccines worldwide, all of which are highly uncertain and cannot be predicted with certainty at this time.
Cyclicality in the petrochemical industry has in the past, and may in the future, result in reduced operating margins or operating losses.
Our historical operating results reflect the cyclical and volatile nature of the petrochemical industry. The industry is mature and capital intensive. Margins in this industry are sensitive to supply and demand balances both domestically and internationally, which historically have been cyclical. The cycles are generally characterized by periods of tight supply, leading to high operating rates and margins, followed by periods of oversupply primarily resulting from excess new capacity additions, leading to reduced operating rates and lower margins.
Moreover, profitability in the petrochemical industry is affected by the worldwide level of demand along with vigorous price competition which may intensify due to, among other things, new industry capacity. In general, weak economic conditions reduce demand and put pressure on margins. It is not possible to predict accurately the supply and demand balances, market conditions and other factors that will affect industry operating margins in the future.
New capacity additions, principally of olefins in North America, Asia and the Middle East, a number of which have been recently completed, may lead to periods of over-supply and lower profitability. As a result, our Performance and Essential Materials segment operating margins may be negatively impacted.
We sell commodity products in highly competitive markets and face significant competition and price pressure.
We sell our products in highly competitive markets. Due to the commodity nature of many of our products, competition in these markets is based primarily on price and to a lesser extent on performance, product quality, product deliverability and customer service. As a result, we generally are not able to protect our market position for these products by product differentiation and may not be able to pass on cost increases to our customers. Accordingly, increases in raw material and other costs may not necessarily correlate with changes in prices for these products, either in the direction of the price change or in magnitude. Specifically, timing differences in pricing between raw material prices, which may change daily, and contract product prices, which in many cases are negotiated monthly or less often, sometimes with an additional lag in effective dates for increases, have had and may continue to have a negative effect on profitability. Significant volatility in raw material costs tends to place pressure on product margins as sales price increases could lag behind raw material cost increases. Conversely, when raw material costs decrease, customers could seek relief in the form of lower sales prices.
Volatility in costs of raw materials and energy may result in increased operating expenses and adversely affect our results of operations and cash flows.
Significant variations in the costs and availability of raw materials and energy may negatively affect our results of operations. These costs have risen significantly in the past due primarily to oil and natural gas cost increases. We purchase significant amounts of ethane feedstock, natural gas, ethylene and salt to produce several basic chemicals. We also purchase significant amounts of electricity to supply the energy required in our production processes. The cost of these raw materials and energy, in the aggregate, represents a substantial portion of our operating expenses. The prices of raw materials and energy generally follow price trends of, and vary with market conditions for, crude oil and natural gas, which are highly volatile and cyclical, as well as the ability of domestic producers to export natural gas liquids, ethane and ethylene. Changes to regulatory policies applicable to the German energy sector for industrial users have contributed to higher prices for industrial users of energy in the past and may continue to do so in the future. Our results of operations have been and could in the future be significantly affected by increases in these costs.
Price increases increase our working capital needs and, accordingly, can adversely affect our liquidity and cash flows. In addition, because we utilize the first-in, first-out ("FIFO") method of inventory accounting, during periods of falling raw material prices and declining sales prices, our results of operations for a particular reporting period could be negatively impacted as the lower sales prices would be reflected in operating income more quickly than the corresponding drop in feedstock costs. We use derivative instruments in an attempt to reduce price volatility risk on some feedstock commodities. In the future, we may decide not to hedge any of our raw material costs or any hedges we enter into may not have successful results. Also, our hedging activities involve credit risk associated with our hedging counterparties, and a deterioration in the financial markets could adversely affect our hedging counterparties and their abilities to fulfill their obligations to us.
Lower prices of crude oil, such as those experienced from the third quarter of 2014 through 2020, led to a reduction in the cost advantage for natural gas liquids-based ethylene crackers in North America, such as ours, as compared to naphtha-based ethylene crackers. As a result, our margins and cash flows were negatively impacted. Lower crude oil and natural gas prices could lead to a reduction in hydraulic fracturing in the United States, which could reduce the availability of feedstock and increase prices of feedstock for our operations. Higher natural gas prices could also adversely affect our ability to export products that we produce in the United States. In addition to the impact that this has on our exports from the United States, reduced competitiveness of U.S. producers also has in the past increased the availability of chemicals in North America, as U.S. production that would otherwise have been sold overseas was instead offered for sale domestically, resulting in excess supply and lower prices in North America. We could also face the threat of imported products from countries that have a cost advantage. Furthermore, additional export storage facilities for natural gas liquids, ethane and ethylene may lead to higher exports of such products from the United States or greater restrictions on hydraulic fracturing could restrict the availability of our raw materials in the United States, thereby increasing our costs.
External factors beyond our control can cause fluctuations in demand for our products and in our prices and margins, which may negatively affect our results of operations and cash flows.
External factors beyond our control can cause volatility in raw material prices, demand for our products, product prices and volumes and deterioration in operating margins. These factors can also magnify the impact of economic cycles on our business and results of operations. Examples of external factors include:
•general economic conditions, including in the United States, Europe and Asia;
•new capacity additions in North America, Europe, Asia and the Middle East;
•the level of business activity in the industries that use our products;
•competitor action;
•technological innovations;
•currency fluctuations;
•increases in interest rates;
•international events and circumstances;
•pandemics and other public health threats and efforts to contain their transmission;
•war, sabotage, terrorism and civil unrest;
•governmental regulation, including in the United States, Europe and Asia;
•public attitude towards climate change and safety, health and the environment;
•perceptions of our products by potential buyers of our products, as well as the public generally, and related changes in behavior, including with respect to recycling;
•severe weather and natural disasters; and
•credit worthiness of customers and vendors.
A number of our products are highly dependent on durable goods markets, such as housing and construction, which are themselves particularly cyclical. Weakness in the U.S. residential housing market and economic weakness in Europe could have an adverse effect on demand and margins for our products.
We may reduce production at or idle a facility for an extended period of time or exit a business because of high raw material prices, an oversupply of a particular product and/or a lack of demand for that particular product, which makes production uneconomical. Temporary outages sometimes last for several quarters or, in certain cases, longer and cause us to incur costs, including the expenses of maintaining and restarting these facilities. Factors such as increases in raw material costs or lower demand in the future may cause us to further reduce operating rates, idle facilities or exit uncompetitive businesses.
A lower level of economic activity in the United States, Europe or globally could result in a decline in demand for our products, which could adversely affect our net sales and margins and limit our future growth prospects. In addition, these risks could cause increased instability in the financial and insurance markets and could adversely affect our ability to access capital and to obtain insurance coverage that we consider adequate or is otherwise required by our contracts with third parties.
The housing market may not continue to grow at the same rate, or may decline, and any decline in the homebuilding industry may adversely affect our operating results.
We cannot predict whether and to what extent the housing market in the United States will continue to grow, particularly if interest rates for mortgage loans and construction costs rise. Other factors that might impact growth in the homebuilding industry include uncertainty in domestic and international financial, credit and consumer lending markets amid slow economic growth or recessionary conditions in various regions or industries around the world, including as a result of the COVID-19 pandemic, tight lending standards and practices for mortgage loans that limit consumers' ability to qualify for mortgage financing to purchase a home, higher home prices, population declines or slower rates of population growth or U.S. Federal Reserve policy changes. Given these factors, we can provide no assurance that the present housing market will continue to be strong.
If there is limited economic growth, a decline in employment and consumer income, a general change in consumer behavior, including as a result of the COVID-19 pandemic, and/or tightening of mortgage lending standards, practices and regulation, or if interest rates for mortgage loans or home prices rise, there could be a corresponding adverse effect on our financial condition, results of operations or cash flows, including, but not limited to, the amount of revenues or profits we generate in our housing and infrastructure products segment.
We operate internationally and are subject to related risks, including exchange rate fluctuations, exchange controls, political risk and other risks relating to international operations.
We operate internationally and are subject to the risks of doing business on a global basis. These risks include, but are not limited to, fluctuations in currency exchange rates, currency devaluations, imposition or the threat of trade barriers (which could, among other things, negatively impact our ability to export our products outside of the United States), imposition or the threat of tariffs and duties (which could, among other things, lead to lower demand for our products outside of the United States), restrictions on the transfer of funds, changes in law and regulatory requirements, involvement in judicial proceedings in unfavorable jurisdictions, economic instability and disruptions, political unrest and epidemics. U.S. foreign trade policies could lead to the imposition of additional trade barriers and tariffs on us in foreign jurisdictions. Our operating results could be negatively affected by any of these risks.
Our inability to compete successfully may reduce our operating profits.
The industries in which we operate are highly competitive. Historically, there have been a number of mergers, acquisitions, spin-offs and joint ventures in the industry. This restructuring activity has resulted in fewer but more competitive producers, many of which are larger than we are and have greater financial resources than we do. Among our competitors are some of the world's largest chemical companies and chemical industry joint ventures. Competition within the petrochemical industry and in the manufacturing of housing and infrastructure products is affected by a variety of factors, including:
•product price;
•balance of product supply/demand;
•material, technology and process innovation;
•technical support and customer service;
•quality;
•reliability of raw material and utility supply;
•availability of potential substitute materials; and
•product performance.
Changes in the competitive environment could have a material adverse effect on our business and our operations. These changes could include:
•the emergence of new domestic and international competitors;
•the rate of capacity additions by competitors;
•the additions of export storage facilities for natural gas liquids, ethane and ethylene;
•changes in customer base due to mergers;
•the intensification of price competition in our markets;
•the introduction of new or substitute products by competitors; and
•the technological innovations of competitors.
Our production facilities process some volatile and hazardous materials that subject us to operating risks that could adversely affect our operating results.
We have manufacturing sites in North America, Europe and Asia. Our operations are subject to the usual hazards associated with chemical, plastics, housing and infrastructure products manufacturing and the related use, storage, transportation and disposal of feedstocks, products and wastes, including:
•pipeline leaks and ruptures;
•explosions;
•fires;
•severe weather and natural disasters;
•mechanical failure;
•unscheduled downtime;
•labor difficulties;
•transportation interruptions;
•transportation accidents involving our products;
•remediation complications;
•chemical spills, discharges or releases of toxic or hazardous substances or gases;
•other environmental risks;
•sabotage;
•terrorist attacks; and
•political unrest.
Global climate change could result in heightened hurricane activity in the Gulf of Mexico and other weather and natural disaster hazards worldwide. If this materializes, severe weather and natural disaster hazards could pose an even greater risk for our facilities, particularly those in Louisiana.
All these hazards can cause personal injury and loss of life, catastrophic damage to or destruction of property and equipment and environmental damage, and may result in a suspension of operations and the imposition of civil or criminal penalties. We are from time to time subject to environmental claims brought by governmental entities or third parties. A loss or shutdown over an extended period of operations at any one of our chemical manufacturing facilities would have a material adverse effect on us. We maintain property, business interruption and casualty insurance that we believe is in accordance with customary industry practices, but we cannot be fully insured against all potential hazards incident to our business, including losses resulting from war risks or terrorist acts. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our financial condition, results of operations or cash flows.
We are exposed to significant losses from products liability, personal injury and other claims relating to the products we manufacture. Additionally, individuals currently seek, and likely will continue to seek, damages for alleged personal injury or property damage due to alleged exposure to chemicals at our facilities or to chemicals otherwise owned, controlled or manufactured by us. We are also subject to present and future claims with respect to workplace exposure, workers' compensation and other matters. Any such claims, whether with or without merit, could be time consuming, expensive to defend and could divert management's attention and resources. We maintain and expect to continue to maintain insurance for products liability, workplace exposure, workers' compensation and other claims, but the amount and scope of such insurance may not be adequate or available to cover a claim that is successfully asserted against us. In addition, such insurance could become more expensive and difficult to maintain and may not be available to us on commercially reasonable terms or at all. The results of any future litigation or claims are inherently unpredictable, but such outcomes could have a material adverse effect on our financial condition, results of operations or cash flows.
We rely on a limited number of outside suppliers for specified feedstocks and services.
We obtain a significant portion of our raw materials from a few key suppliers. If any of these suppliers is unable to meet its obligations under any present or future supply agreements, we may be forced to pay higher prices to obtain the necessary raw materials. Any interruption of supply or any price increase of raw materials could have a material adverse effect on our business and results of operations. A vendor may choose, subject to existing contracts, to modify its relationship due to general economic concerns or concerns relating to the vendor or us, at any time. Any significant change in the terms that we have with our key suppliers, or any significant additional requirements from our suppliers that we provide them additional security in the form of prepayments or with letters of credits, could materially adversely affect our financial condition, results of operations or cash flows.
We rely heavily on third party transportation, which subjects us to risks and costs that we cannot control. Such risks and costs may materially adversely affect our operations.
We rely heavily on railroads, barges, pipelines, ships, trucks and other shipping companies to transport raw materials to the manufacturing facilities used by our businesses and to ship finished products to customers. These transport operations are subject to various hazards and risks, including extreme weather conditions, work stoppages and operating hazards (including pipeline leaks and ruptures and storage tank leaks), as well as interstate transportation regulations. In addition, the methods of transportation we utilize, including shipping chlorine and other chemicals by railroad, may be subject to additional, more stringent and more costly regulations in the future. If we are delayed or unable to ship finished products or unable to obtain raw materials as a result of any such new regulations or public policy changes related to transportation safety, or these transportation companies fail to operate properly, or if there were significant changes in the cost of these services due to new or additional regulations, or otherwise, we may not be able to arrange efficient alternatives and timely means to obtain raw materials or ship goods, which could result in a material adverse effect on our business and results of operations.
We may pursue acquisitions, dispositions and joint ventures and/or other transactions that may impact our results of operations and financial condition. We may have difficulties integrating the operations of the Boral Target Companies, LASCO, Dimex, Hexion epoxy, and future acquired businesses.
We seek opportunities to maximize efficiency and create stockholder value through various transactions. These transactions may include domestic and international business combinations, purchases or sales of assets or contractual arrangements or joint ventures. In this regard, we regularly consider acquisition opportunities that would be consistent or complementary to our existing business strategies. To the extent permitted under our credit facility, the indenture governing our senior notes and other debt agreements, some of these transactions may be financed by additional borrowings by us. Although we would pursue these transactions because we expect them to yield longer-term benefits if the efficiencies and synergies we expect are realized, they could adversely affect our results of operations in the short term because of the costs associated with such transactions and because they may divert management's attention from existing business operations. These transactions may not yield the business benefits, synergies or financial benefits anticipated by management. Integration of acquired operations could lead to restructuring charges or other costs.
Our ability to realize the anticipated benefits of the Acquisitions will depend, to a large extent, on our ability to integrate our business with the businesses of the Boral Target Companies, LASCO, Dimex and Hexion epoxy. The combination of such independent businesses is a complex, costly and time-consuming process. As a result, we have devoted, and will continue to devote significant management attention and resources to integrating each of the Boral Target Companies', LASCO's, Dimex's and Hexion epoxy's business practices and operations with our existing business practices and operations. The integration process may disrupt the businesses and, if implemented ineffectively or if impacted by unforeseen negative economic or market conditions or other factors, we may not realize the full anticipated benefits of the Acquisitions. Our failure to meet the challenges involved in integrating such businesses could adversely affect our results of operations.
In addition, the overall integration of the businesses may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships, or diversion of management's attention. Even if the operations of our businesses and the businesses of the Boral Target Companies, LASCO, Dimex and Hexion epoxy are integrated successfully, we may not realize the full benefits of the Acquisitions, including the synergies, cost savings or sales or growth opportunities that we expect. These benefits may not be achieved within the anticipated time frame, or at all. Furthermore, additional unanticipated costs may be incurred in the integration of the businesses. All of these factors could decrease or delay the expected benefits of the Acquisitions and negatively impact us.
If we are unable to integrate or to successfully manage businesses that we may acquire in the future, our business, financial condition and results of operations could be adversely affected. We may not be able to realize the operating efficiencies, synergies, cost savings or other benefits expected from acquisitions for a number of reasons, including the following:
•we may fail to integrate the businesses we acquire into a cohesive, efficient enterprise;
•our resources, including management resources, are limited and may be strained if we engage in a large acquisition or significant number of acquisitions, and acquisitions may divert our management's attention from initiating or carrying out programs to save costs or enhance revenues; and
•our failure to retain key employees and contracts of the businesses we acquire.
Our operations and assets are subject to extensive environmental, health and safety laws and regulations.
We use large quantities of hazardous substances and generate hazardous wastes and emissions in our manufacturing operations. Due to the associated quantities of hazardous substances and wastes, our industry is highly regulated and monitored by various environmental regulatory authorities such as the EPA, federal or state analogs in other countries and the European Union, which promulgated the Industrial Emission Directive ("IED"). As such, we are subject to extensive international, national, state and local laws, regulations and directives pertaining to pollution and protection of the environment, health and safety, which govern, among other things, emissions to the air, discharges onto land or waters, the maintenance of safe conditions in the workplace, the remediation of contaminated sites, and the generation, handling, storage, transportation, treatment and disposal of waste materials. Some of these laws, regulations and directives are subject to varying and conflicting interpretations. Many of these laws, regulations and directives provide for substantial fines and potential criminal sanctions for violations and require the installation of costly pollution control equipment or operational changes to limit pollution emissions or reduce the likelihood or impact of hazardous substance releases, whether permitted or not. For example, all of our petrochemical facilities in the United States and Europe may require improvements to comply with certain changes in process safety management requirements.
New laws, rules and regulations as well as changes to laws, rules and regulations may also affect us. For example, on April 17, 2012, the EPA promulgated maximum achievable control technology standards for major sources and generally available control technology standards for area sources of PVC production. The rule sets emission limits and work practice standards for total organic air toxics and for three specific air toxics: vinyl chloride, chlorinated di-benzo dioxins and furans and hydrogen chloride and includes requirements to demonstrate initial and continuous compliance with the emission standards. In June 2012, the EPA received petitions for reconsideration of the rule. On November 9, 2020, the EPA proposed rule amendments to address issues raised in the petitions for reconsideration. While this rule is the subject of legal challenge and EPA reconsideration, the rule has not been stayed. Although we cannot predict the outcome or timing of the legal challenges or EPA reconsideration, the EPA's proposed rule amendments could require us to incur further capital expenditures, or increase our operating costs, to levels higher than what we have previously estimated.
In March 2011, the EPA proposed amendments to the national emission standards for hazardous air pollutants ("NESHAPs") for mercury emissions from mercury cell chlor-alkali plants. These proposed amendments would require improvements in work practices to reduce fugitive mercury emissions. In addition, on January 8, 2021, the EPA proposed amendments to the 2003 NESHAPs for mercury cell chlor-alkali plants residual risk and technology review. Among other things, the proposed rule would require work practice standards for the cell rooms and instrumental monitoring of cell room fugitive emissions, modify regulatory provisions regarding startup, shutdown, and malfunctions, and add standards for fugitive chlorine emissions from mercury cell chlor-alkali plants, which are not currently regulated under the NESHAP. The EPA extended the public comment period on the proposed rule to March 24, 2021. The EPA has yet to publish the final rule and we cannot predict the timing or content of the final regulation. We operate a mercury cell production unit at our Natrium facility. If the proposed amendments were finalized, they could result in additional restrictions on our operations or increased compliance costs.
Our operations produce greenhouse gas ("GHG") emissions, which have been the subject of increased scrutiny and regulation. In December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris Agreement calls for the parties to undertake "ambitious efforts" to limit the average global temperature and to conserve and enhance sinks and reservoirs of greenhouse gases. The United States signed the Paris Agreement in April 2016, and the Paris Agreement went into effect in November 2016. In November 2019, the United States submitted formal notification to the United Nations that it intended to withdraw from the Paris Agreement. The withdrawal took effect in November 2020. However, President Biden signed an executive order on January 20, 2021 for reentry of the United States into the Paris Agreement and on February 19, 2021, President Biden formally rejoined the Paris Agreement. As part of rejoining the Paris Agreement, President Biden announced that the United States would commit to a 50 to 52 percent reduction from 2005 levels of GHG emissions by 2030 and set the goal of reaching net-zero GHG emissions by 2050. Legislation to regulate GHG emissions has periodically been introduced in the United States Congress, and such legislation may be proposed or adopted in the future. There has been a wide-ranging policy debate regarding the impact of these gases and possible means for their regulation. Some of the proposals would require industries to meet stringent new standards that would require substantial reductions in carbon emissions. The adoption and implementation of any international, federal or state legislation or regulations that restrict emissions of GHGs could result in increased compliance costs or additional operating restrictions.
Various jurisdictions have considered or adopted laws and regulations on GHG emissions, with the general aim of reducing such emissions. The EPA currently requires certain industrial facilities to report their GHG emissions, and to obtain permits with stringent control requirements before constructing or modifying new facilities with significant GHG emissions. In the European Union, the Emissions Trading Scheme obligates certain emitters to obtain GHG emission allowances to comply with a cap and trade system for GHG emissions. In addition, the European Union has committed to reduce domestic GHG emissions by at least 55% below the 1990 level by 2030. As our chemical manufacturing processes result in GHG emissions, these and other GHG laws and regulations could affect our costs of doing business.
Similarly, the Toxic Substances Control Act ("TSCA") imposes reporting, record-keeping and testing requirements, and restrictions relating to the production, handling, and use of chemical substances. The TSCA reform legislation enacted in June 2016 expanded the EPA's authority to review and regulate new and existing chemicals. Under the reform legislation, the EPA is required to, among other things, undertake rule making within statutory time frames related to: (1) chemical risk evaluation, designation and management; (2) reporting of mercury supply, use and trade; and (3) management of persistent, bioaccumulative, and toxic chemical substances ("PBTs"). In response to this mandate, the EPA issued rules establishing the EPA's process and criteria for identifying high priority chemicals for risk evaluation and setting the EPA's approach for determining whether these high priority chemicals present an unreasonable risk to health or the environment. Pursuant to its rules, the EPA designated certain chemical substances as high priority for risk evaluation. We manufacture several of these chemical substances. Although we cannot predict with certainty the extent of our future liabilities and costs at this time, we do not anticipate that the evaluation of these chemical substances will have a material adverse effect on our business, financial condition, operating results or cash flows. In addition, the TSCA inventory reset rule required industry reporting of chemicals manufactured or processed in the United States over a 10-year period ending in 2016. This reporting is used by the EPA to identify which chemicals are active or inactive on the TSCA Inventory. Beginning in 2019, chemical manufacturers and processors are required to notify and obtain approval by the EPA before reintroducing inactive chemicals into commerce. A final mercury reporting rule published in June 2018 requires manufacturers, including manufacturers who use mercury in a manufacturing process, to report information about their mercury supply, use and trade. The first periodic reporting deadline under the mercury reporting rule was July 1, 2019. The EPA used the information collected to develop an inventory of mercury and mercury-added products as well as mercury-use manufacturing processes. The EPA also recommended actions and rule amendments based on the collected information. We cannot predict the timing or content of these actions or amendments, or their ultimate cost to, or impact on us.
On June 28, 2021, the EPA proposed reporting and recordkeeping requirements for Per- and Polyfluoroalkyl Substances ("PFAS") under TSCA. The proposed rule would require manufacturers, and importers, that have manufactured or imported PFAS chemicals since January 1, 2011, to electronically report information regarding PFAS uses, production volumes, disposal, exposures, and hazards. The EPA has not yet issued a final rule; however, PFAS chemicals have come under increased scrutiny by federal, state, and local governments. For example, many states have banned the use of PFAS in certain consumer products and set Maximum Contaminant Levels for PFAS in drinking water. The EPA is also considering regulating certain PFAS chemicals under the Safe Drinking Water Act, and has announced that it intends to develop a proposed National Primary Drinking Water Regulation for perfluorooctanesulfonic acid ("PFOS") and perfluorooctanoic acid ("PFOA"), two of the most common PFAS chemicals. We are unable to predict the impact these requirements and concepts may have on our future costs of compliance.
Under the IED, European Union member state governments are expected to adopt rules and implement environmental permitting programs relating to air, water and waste for industrial facilities. In this context, concepts such as the "best available technique" are being explored. Future implementation of these concepts may result in technical modifications in our European facilities. In addition, under the Environmental Liability Directive, European Union member states can require the remediation of soil and groundwater contamination in certain circumstances, under the "polluter pays principle." We are unable to predict the impact these requirements and concepts may have on our future costs of compliance.
Local, state, federal and foreign governments have increasingly proposed or implemented restrictions on certain plastic-based products, including single-use plastics and plastic food packaging. Plastics have also faced increased public scrutiny due to negative coverage of plastic waste in the environment. Increased regulation on the use of plastics could cause reduced demand for our polyethylene products, which could adversely affect our business, operating results and financial condition.
These rules or future new, amended or proposed laws or rules could increase our costs or reduce our production, which could have a material adverse effect on our business, financial condition, operating results or cash flows. In addition, we cannot accurately predict future developments, such as increasingly strict environmental and safety laws or regulations, and inspection and enforcement policies, as well as resulting higher compliance costs, which might affect the handling, manufacture, use, emission, disposal or remediation of products, other materials or hazardous and non-hazardous waste, and we cannot predict with certainty the extent of our future liabilities and costs under environmental, health and safety laws and regulations. These liabilities and costs may be material.
We also may face liability for alleged personal injury or property damage due to exposure to chemicals or other hazardous substances at our facilities or to chemicals that we otherwise manufacture, handle or own. Although these types of claims have not historically had a material impact on our operations, a significant increase in the success of these types of claims could have a material adverse effect on our business, financial condition, operating results or cash flows.
Environmental laws may have a significant effect on the nature and scope of, and responsibility for, cleanup of contamination at our current and former operating facilities, the costs of transportation and storage of raw materials and finished products, the costs of reducing emissions and the costs of the storage and disposal of wastewater. The U.S. Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), similar state laws and certain European directives impose joint and several liability for the costs of remedial investigations and actions on the entities that generated waste, arranged for disposal of the wastes, transported to or selected the disposal sites and the past and present owners and operators of such sites. All such potentially responsible parties (or any one of them, including us) may be required to bear all of such costs regardless of fault, legality of the original disposal or ownership of the disposal site. In addition, CERCLA, similar state laws and certain European directives could impose liability for damages to natural resources caused by contamination.
Although we seek to take preventive action, our operations are inherently subject to accidental spills, discharges or other releases of hazardous substances that may make us liable to governmental entities or private parties. This may involve contamination associated with our current and former facilities, facilities to which we sent wastes or by-products for treatment or disposal and other contamination. Accidental discharges may occur in the future, future action may be taken in connection with past discharges, governmental agencies may assess damages or penalties against us in connection with any past or future contamination, or third parties may assert claims against us for damages allegedly arising out of any past or future contamination. In addition, we may be liable for existing contamination related to certain of our facilities for which, in some cases, we believe third parties are liable in the event such third parties fail to perform their obligations.
Capital projects are subject to risks, including delays and cost overruns, which could have an adverse impact on our financial condition and results of operations.
We have capital expansion plans for our facilities. Expansion projects may be subject to delays or cost overruns, including delays or cost overruns resulting from any one or more of the following:
•unexpectedly long delivery times for, or shortages of, key equipment, parts or materials;
•shortages of skilled labor and other personnel necessary to perform the work;
•delays and performance issues;
•failures or delays of third-party equipment vendors or service providers;
•unforeseen increases in the cost of equipment, labor and raw materials;
•work stoppages and other labor disputes;
•unanticipated actual or purported change orders;
•disputes with contractors and suppliers;
•design and engineering problems;
•latent damages or deterioration to equipment and machinery in excess of engineering estimates and assumptions;
•financial or other difficulties of our contractors and suppliers;
•sabotage;
•terrorist attacks;
•interference from adverse weather conditions; and
•difficulties in obtaining necessary permits or in meeting permit conditions.
Significant cost overruns or delays could materially affect our financial condition and results of operations. Additionally, actual capital expenditures could materially exceed our planned capital expenditures.
Our level of debt could adversely affect our ability to operate our business.
As of December 31, 2021, our indebtedness, including the current portion, totaled $5.2 billion, and our debt represented approximately 38% of our total capitalization. Our annual interest expense for 2021 was $176 million, net of interest capitalized of $3 million. Our level of debt and the limitations imposed on us by our existing or future debt agreements could have significant consequences on our business and future prospects, including the following:
•a portion of our cash flows from operations will be dedicated to the payment of interest and principal on our debt and will not be available for other purposes;
•we may not be able to obtain necessary financing in the future for working capital, capital expenditures, acquisitions, debt service requirements or other purposes;
•our less leveraged competitors could have a competitive advantage because they have greater flexibility to utilize their cash flows to improve their operations;
•we may be exposed to risks inherent in interest rate fluctuations because some of our borrowings are at variable rates of interest, which would result in higher interest expense in the event of increases in interest rates;
•we could be vulnerable in the event of a downturn in our business that would leave us less able to take advantage of significant business opportunities and to react to changes in our business and in market or industry conditions; and
•should we pursue additional expansions of existing assets or acquisition of third-party assets, we may not be able to obtain additional liquidity at cost effective interest rates.
These factors could be magnified or accelerated to the extent we were to finance future acquisitions with significant amounts of debt.
To service our indebtedness and fund our capital requirements, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.
Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures and pay cash dividends will depend on our ability to generate cash in the future, including any distributions that we may receive from Westlake Partners. This is subject to general economic, financial, currency, competitive, legislative, regulatory and other factors that are beyond our control.
Our business may not generate sufficient cash flows from operations, we may not receive sufficient distributions from Westlake Partners, and currently anticipated cost savings and operating improvements may not be realized on schedule. We also generate revenues denominated in currencies other than that of our indebtedness and may have difficulty converting those revenues into the currency of our indebtedness. We may need to refinance all or a portion of our indebtedness on or before maturity. In addition, we may not be able to refinance any of our indebtedness, including our credit facility and our senior notes, on commercially reasonable terms or at all. All of these factors could be magnified if we were to finance any future acquisitions with significant amounts of debt.
The Credit Agreement and the indenture governing certain of our senior notes impose significant operating and financial restrictions, which may prevent us from capitalizing on business opportunities and taking some actions.
The Credit Agreement and the indenture governing certain of our senior notes impose significant operating and financial restrictions on us. These restrictions limit our ability to:
•incur additional indebtedness;
•create liens;
•sell all or substantially all of our assets or consolidate or merge with or into other companies; and
•engage in sale-leaseback transactions.
These limitations are subject to a number of important qualifications and exceptions. The Credit Agreement also requires us to maintain a quarterly total leverage ratio.
These covenants may adversely affect our ability to finance future business opportunities or acquisitions. A breach of any of these covenants could result in a default in respect of the related debt. If a default occurred, the relevant lenders could elect to declare the debt, together with accrued interest and other fees, to be immediately due and payable. In addition, any acceleration of debt under the Credit Agreement will constitute a default under some of our other debt, including the indentures governing our senior notes.
Our participation in joint ventures and similar arrangements exposes us to a number of risks, including risks of shared control.
We are party to several joint ventures and similar arrangements, including an investment, together with Lotte Chemical USA Corporation ("Lotte"), in a joint venture, LACC, LLC ("LACC"), to build and operate an ethylene facility. Our participation in joint ventures and similar arrangements, by their nature, requires us to share control with unaffiliated third parties. If there are differences in views among joint venture participants in how to operate a joint venture that result in delayed decisions or the failure to make decisions, or our joint venture partners do not fulfill their obligations, the affected joint venture may not be able to operate according to its business plan and fulfill its obligations. In that case, we may be required to write down the value of our investment in a joint venture, increase the level of financial or other commitments to the joint venture or, if we have contractual agreements with the joint venture, our operations may be materially adversely affected. Any of the foregoing could have a material adverse effect on our financial condition, results of operations or cash flows.
Our operations could be adversely affected by labor relations.
The vast majority of our employees in Europe and Asia, and some of our employees in North America, are represented by labor unions and works councils. Our operations may be adversely affected by strikes, work stoppages and other labor disputes.
We have certain material pension and other post-retirement employment benefit ("OPEB") obligations. Future funding obligations related to these obligations could restrict cash available for our operations, capital expenditures or other requirements or require us to borrow additional funds.
We have U.S. and non-U.S. defined benefit pension plans covering certain current and former employees. Certain non-U.S. defined benefit plans associated with our European operations have not been funded and we are not obligated to fund those plans under applicable law. As of December 31, 2021, the projected benefit obligations for our pension and OPEB plans were $825 million and $62 million, respectively. The fair value of pension investment assets was $583 million as of December 31, 2021. The total underfunded status of the pension obligations calculated on a projected benefit obligation basis as of December 31, 2021 was $242 million, including the Westlake Defined Benefit Plan and the Vinnolit Pension Plan (locally known as 'Grund- und Zusatzversorgung' in Germany), which were underfunded by $83 million and $128 million, respectively, on an individual plan basis.
The unfunded OPEB obligations as of December 31, 2021 were $62 million. We will require future operating cash flows to fund our pension and OPEB obligations, which could restrict available cash for our operations, capital expenditures and other requirements. We may also not generate sufficient cash to satisfy these obligations, which could require us to seek funding from other sources, including through additional borrowings, which could materially increase our outstanding debt or debt service requirements.
If our goodwill, indefinite-lived intangible assets or other intangible assets become impaired in the future, we may be required to record non-cash charges to earnings, which could be significant.
Under GAAP, we review goodwill and indefinite-lived intangible assets for impairment on an annual basis or more frequently if events or circumstances indicate that their carrying value may not be recoverable. Other intangible assets are reviewed if events or circumstances indicate that their carrying value may not be recoverable. The process of impairment testing for our goodwill and intangible assets involves a number of judgments and estimates made by management including the fair values of assets and liabilities, future cash flows, our interpretation of current economic indicators and market conditions, overall economic conditions and our strategic operational plans with regards to our business units. If the judgments and estimates used in our analysis are not realized or change due to external factors, then actual results may not be consistent with these judgments and estimates, and our goodwill and intangible assets may become impaired in future periods. If our goodwill, indefinite-lived intangible assets or other intangible assets are determined to be impaired in the future, we may be required to record non-cash charges to earnings during the period in which the impairment is determined, which could be significant and have an adverse effect on our financial condition and results of operations.
Failure to adequately protect critical data and technology systems could materially affect our operations.
Information technology system failures, network disruptions and breaches of data security due to internal or external factors including cyber-attacks could disrupt our operations by causing delays or cancellation of customer orders, impede the manufacture or shipment of products or cause standard business processes to become ineffective, resulting in the unintentional disclosure of information or damage to our reputation. Cyber-attacks could include, but are not limited to, ransomware attacks, malicious software, attempts to gain unauthorized access to our data and the unauthorized release, corruption or loss of our data and personal information, interruptions in communication, loss of our intellectual property or theft of our sensitive or proprietary technology, loss or damage to our data delivery systems, or other cybersecurity and infrastructure systems, including our property and equipment. We have taken steps to address these risks by implementing network security and internal control measures, including employee training, comprehensive monitoring of our networks and systems, maintenance of backup and protective systems and disaster recovery and incident response plans. Our employees, systems, networks, products, facilities and services remain potentially vulnerable to sophisticated cyber-assault, especially while certain employees are working remotely during the COVID-19 pandemic, and, as such, there can be no assurance that a system failure, network disruption or data security breach will not have a material adverse effect on our business, financial condition, operating results or cash flows.
Fluctuations in foreign currency exchange and interest rates could affect our consolidated financial results.
We earn revenues, pay expenses, own assets and incur liabilities in countries using currencies other than the U.S. dollar. Because our consolidated financial statements are presented in U.S. dollars, we must translate revenues and expenses into U.S. dollars at the average exchange rate during each reporting period, as well as assets and liabilities into U.S. dollars at exchange rates in effect at the end of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar against other major currencies will affect our net sales, operating income and the value of balance sheet items denominated in foreign currencies. Because of the geographic diversity of our operations, weaknesses in various currencies might occur in one or many of such currencies over time. From time to time, we may use derivative financial instruments to further reduce our net exposure to currency exchange rate fluctuations. However, fluctuations in foreign currency exchange rates, such as the strengthening of the U.S. dollar against major currencies, including, in particular, the Euro and the Canadian dollar, could nevertheless materially adversely affect our financial results.
In addition, we are exposed to volatility in interest rates. When appropriate, we may use derivative financial instruments to reduce our exposure to interest rate risks. However, our financial risk management program may not be successful in reducing the risks inherent in exposures to interest rate fluctuations.
Our property insurance has only partial coverage for acts of terrorism and, in the event of terrorist attack, we could lose net sales and our facilities.
Our insurance carriers maintain certain exclusions for losses from terrorism from our property insurance policies. While separate terrorism insurance coverage is available, premiums for full coverage are very expensive, especially for chemical facilities, and the policies are subject to high deductibles. Available terrorism coverage typically excludes coverage for losses from acts of war and from acts of foreign governments as well as nuclear, biological and chemical attacks. We have determined that it is not economically prudent to obtain full terrorism insurance, especially given the significant risks that are not covered by such insurance. Where feasible we have secured some limited terrorism insurance coverage on our property where insurers have included it in their overall programs. In the event of a terrorist attack impacting one or more of our facilities, we could lose the net sales from the facilities and the facilities themselves, and could become liable for any contamination or for personal or property damage due to exposure to hazardous materials caused by any catastrophic release that may result from a terrorist attack.
Risks Related to Taxes
A change in tax laws, treaties or regulations, or their interpretation or application, could have a negative impact on our business and results of operations.
We operate in many different countries and in many states within the United States, and we are subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which we operate. A material change in these tax laws, treaties or regulations, or their interpretation or application, could have a negative impact on our business and results of operations.
We depend in part on distributions from Westlake Partners to generate cash for our operations, capital expenditures, debt service and other uses. Westlake Partners' tax treatment depends on its status as a partnership for federal income tax purposes, and it not being subject to a material amount of entity-level taxation. If the Internal Revenue Service ("IRS") were to treat Westlake Partners as a corporation for federal income tax purposes, or if Westlake Partners became subject to entity-level taxation for state tax purposes, its cash available for distribution would be substantially reduced, which would also likely cause a substantial reduction in the value of its common units that we hold.
The anticipated after-tax economic benefit of an investment in the common units of Westlake Partners depends largely on Westlake Partners being treated as a partnership for U.S. federal income tax purposes. Despite the fact that Westlake Partners is organized as a limited partnership under Delaware law, it would be treated as a corporation for U.S. federal income tax purposes unless it satisfies a "qualifying income" requirement. Based on Westlake Partners' current operations and current Treasury Regulations, Westlake Partners believes it satisfies the qualifying income requirement.
Prior to its initial public offering, Westlake Partners requested and obtained a favorable private letter ruling from the IRS to the effect that, based on facts presented in the private letter ruling request, income from the production, transportation, storage and marketing of ethylene and its co-products constitutes "qualifying income" within the meaning of Section 7704 of the Internal Revenue Code of 1986, as amended. However, no ruling has been or will be requested regarding Westlake Partners' treatment as a partnership for U.S. federal income tax purposes. Failing to meet the qualifying income requirement or a change in current law could cause Westlake Partners to be treated as a corporation for U.S. federal income tax purposes or otherwise subject Westlake Partners to taxation as an entity.
If Westlake Partners were treated as a corporation for federal income tax purposes, it would pay U.S. federal income tax on its taxable income at the corporate tax rate. Because a tax would be imposed upon Westlake Partners as a corporation, its cash available for distribution to its unitholders would be substantially reduced. Therefore, treatment of Westlake Partners as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to its unitholders, likely causing a substantial reduction in the value of its common units.
Westlake Partners' partnership agreement provides that if a law is enacted or an existing law is modified or interpreted in a manner that subjects Westlake Partners to taxation as a corporation or otherwise subjects Westlake Partners to entity-level taxation for U.S. federal, state, local or foreign income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law or interpretation on Westlake Partners. At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise or other forms of taxation. Westlake Partners currently owns assets and conducts business in several states, most of which impose entity-level franchise or gross receipt taxes on partnerships. Imposition of similar entity-level taxes on Westlake Partners in other jurisdictions in which Westlake Partners conducts operations in the future could substantially reduce its cash available for distribution.
Risks Related to the Ownership of Our Securities
We will be controlled by our principal stockholder and its affiliates as long as they own a majority of our common stock, and our other stockholders will be unable to affect the outcome of stockholder voting during that time. Our interests may conflict with those of the principal stockholder and its affiliates, and we may not be able to resolve these conflicts on terms possible in arms-length transactions.
As long as TTWF LP (the "principal stockholder") and its affiliates (the "principal stockholder affiliates") own a majority of our outstanding common stock, they will be able to exert significant control over us, and our other stockholders, by themselves, will not be able to affect the outcome of any stockholder vote. As a result, the principal stockholder, subject to any fiduciary duty owed to our minority stockholders under Delaware law, will be able to control all matters affecting us (some of which may present conflicts of interest), including:
•the composition of our Board of Directors and, through the Board, any determination with respect to our business direction and policies, including the appointment and removal of officers and the determination of compensation;
•any determinations with respect to mergers or other business combinations or the acquisition or disposition of assets;
•our financing decisions, capital raising activities and the payment of dividends; and
•amendments to our amended and restated certificate of incorporation or amended and restated bylaws.
The principal stockholder will be permitted to transfer a controlling interest in us without being required to offer our other stockholders the ability to participate or realize a premium for their shares of common stock. A sale of a controlling interest to a third party may adversely affect the market price of our common stock and our business and results of operations because the change in control may result in a change of management decisions and business policy. Because we have elected not to be subject to Section 203 of the General Corporation Law of the State of Delaware, the principal stockholder may find it easier to sell its controlling interest to a third party than if we had not so elected.
In addition to any conflicts of interest that arise in the foregoing areas, our interests may conflict with those of the principal stockholder affiliates in a number of other areas, including:
•business opportunities that may be presented to the principal stockholder affiliates and to our officers and directors associated with the principal stockholder affiliates, and competition between the principal stockholder affiliates and us within the same lines of business;
•the solicitation and hiring of employees from each other; and
•agreements with the principal stockholder affiliates relating to corporate services that may be material to our business.
We may not be able to resolve any potential conflicts with the principal stockholder affiliates, and even if we do, the resolution may be less favorable than if we were dealing with an unaffiliated party, particularly if the conflicts are resolved while we are controlled by the principal stockholder affiliates. Our amended and restated certificate of incorporation provides that the principal stockholder affiliates have no duty to refrain from engaging in activities or lines of business similar to ours and that the principal stockholder affiliates will not be liable to us or our stockholders for failing to present specified corporate opportunities to us.
Public and investor sentiment towards climate change and other environmental, social and governance ("ESG") matters could adversely affect our cost of capital and the price of our common stock.
There have been intensifying efforts within the investment community (including investment advisors, investment fund managers, sovereign wealth funds, public pension funds, universities and individual investors) to promote the divestment of, or limit investment in, the stock of companies in the petrochemical industry. There has also been pressure on lenders and other financial services companies to limit or curtail financing of companies in the industry. Because we operate within the petrochemical industry, if these efforts continue or expand, our stock price and our ability to raise capital may be negatively impacted.
Members of the investment community are increasing their focus on ESG practices and disclosures by public companies, including practices and disclosures related to climate change and sustainability, DEI initiatives and heightened governance standards. As a result, we may continue to face increasing pressure regarding our ESG disclosures and practices. Additionally, members of the investment community may screen companies such as ours for ESG disclosures and performance before investing in our stock. Over the past few years, there has also been an acceleration in investor demand for ESG investing opportunities, and many large institutional investors have committed to increasing the percentage of their portfolios that are allocated towards ESG investments. With respect to any of these investors, our ESG disclosures and efforts may not satisfy the investor requirements or their requirements may not be made known to us. If we or our securities are unable to meet the ESG standards or investment criteria set by these investors and funds, we may lose investors or investors may allocate a portion of their capital away from us, our cost of capital may increase, and our stock price may be negatively impacted.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
Overview
We are a vertically integrated global manufacturer and marketer of performance and essential materials and housing and infrastructure products. We have historically operated in two principal operating segments, Vinyls and Olefins. As a result of recent acquisitions, we reorganized our business into two principal operating segments, Performance and Essentials Materials and Housing and Infrastructure Products in the fourth quarter of 2021. Performance and Essential Materials segment includes Westlake North American Vinyls, Westlake North American Chlor-alkali & Derivatives, Westlake European & Asian Chlorovinyls, Westlake Olefins and Westlake Polyethylene. Housing and Infrastructure Products segment includes Westlake Royal Building Products, Westlake Pipe & Fittings, Westlake Global Compounds and Westlake Dimex. The change has been retrospectively reflected in the periods presented in this Form 10-K. We are highly integrated along our materials chain with significant downstream integration from ethylene and chlor-alkali (chlorine and caustic soda) into vinyls, polyethylene and styrene monomer. We also have substantial downstream integration from PVC into our building products, PVC pipes and fittings and PVC compounds in our Housing and Infrastructure Products segment.
Performance and Essentials Materials
Ethane-based ethylene producers have experienced a cost advantage over naphtha-based ethylene producers during periods of higher crude oil prices. This cost advantage has resulted in a strong export market for polyethylene and other ethylene derivatives and has benefited operating margins and cash flows for our Performance and Essential Materials segment during such periods. However, we have seen a significant reduction in the cost advantage enjoyed by North American ethane-based ethylene producers during periods of lower crude oil prices. In the past year, we have seen volatility in ethane and ethylene prices, primarily due to changes in demand resulting from the COVID-19 pandemic, anticipated timing for certain new ethylene capacity additions and availability of natural gas liquids. Additionally, we have seen volatility in ethane and ethylene prices in 2021 due to winter storm Uri and Hurricane Ida that resulted in shutdowns of many industry production facilities on the Gulf Coast and delayed or extended the timing of planned turnarounds of various ethylene crackers.
Our performance and essential materials such as ethylene, PVC, polyethylene and chlor-alkali are some of the most widely used materials in the world and are upgraded into a wide variety of higher value-added products used in many end-markets. Our performance and essential materials are used by customers in food and specialty packaging; industrial and consumer packaging; medical health applications; PVC pipe applications; consumer durables; mobility and transportation; and infrastructure products. Chlor-alkali and petrochemicals are typically manufactured in large volume by a number of different producers using widely available technologies. The chlor-alkali and petrochemical industries exhibit cyclical commodity characteristics, and margins are influenced by changes in the balance between supply and demand and the resulting operating rates, the level of general economic activity and the price of raw materials. Due to the significant size of new plants, capacity additions are built in large increments and typically require several years of demand growth to be absorbed. The cycle is generally characterized by periods of tight supply, leading to high operating rates and margins, followed by a decline in operating rates and margins primarily as a result of excess new capacity additions.
Westlake is the second-largest chlor-alkali producer and the second-largest PVC producer in the world. Demand for our products in the first half of 2020 was negatively impacted by the onset of the COVID-19 pandemic. Global demand for most of our products started strengthening in the second half of 2020 and remained strong throughout 2021, and we expect global demand for most of our products to remain robust in 2022. Depending on the performance of the global economy, potential changes in international trade and tariffs policies, the trend of crude oil prices, the timing of the new capacity additions in North America, Asia and the Middle East in 2022 and beyond, and the sustainability of the current, strong demand for most of our products, our financial condition, results of operations or cash flows could be negatively or positively impacted.
We purchase significant amounts of ethane feedstock, natural gas, ethylene and salt from external suppliers for use in production of performance and essential materials. We also purchase significant amounts of electricity to supply the energy required in our production processes. While we have agreements providing for the supply of ethane feedstock, natural gas, ethylene, salt and electricity, the contractual prices for these raw materials and energy vary with market conditions and may be highly volatile. Factors that have caused volatility in our raw material prices in the past, and which may do so in the future include:
•the availability of feedstock from shale gas and oil drilling;
•supply and demand for crude oil;
•shortages of raw materials due to increasing demand;
•ethane and liquefied natural gas exports;
•capacity constraints due to higher construction costs for investments, construction delays, strike action or involuntary shutdowns;
•the general level of business and economic activity; and
•the direct or indirect effect of governmental regulation.
Significant volatility in raw material costs tends to put pressure on product margins as sales price increases could lag behind raw material cost increases. Conversely, when raw material costs decrease, customers may seek immediate relief in the form of lower sales prices. We currently use derivative instruments to reduce price volatility risk on feedstock commodities and lower overall costs. Normally, there is a pricing relationship between a commodity that we process and the feedstock from which it is derived. When this pricing relationship deviates from historical norms, we have from time to time entered into derivative instruments and physical positions in an attempt to take advantage of this relationship.
Our historical results have been significantly affected by our plant production capacity, our efficient use of that capacity and our ability to increase capacity. Since our inception, we have followed a disciplined growth strategy that focuses on plant acquisitions, new plant construction and internal expansion. We evaluate each expansion project on the basis of its ability to produce sustained returns in excess of our cost of capital and its ability to improve efficiency or reduce operating costs. We also regularly look at acquisition opportunities that would be consistent with, or complimentary to, our overall business strategies. Depending on the size of the acquisition, any such acquisitions could require external financing.
As noted above in Item 1A, "Risk Factors," we are subject to extensive environmental regulations, which may impose significant additional costs on our operations in the future. Further, concerns about GHG emissions and their possible effects on climate change has led to the enactment of regulations, and to proposed legislation and additional regulations, that could affect us in the form of increased cost of feedstocks and fuel, other increased costs of production and decreased demand for our products. While we do not expect any of these enactments or proposals to have a material adverse effect on us in the near term, we cannot predict the longer-term effect of any of these regulations or proposals on our future financial condition, results of operations or cash flows.
Housing and Infrastructure Products
Our Housing and Infrastructure Products segment is primarily comprised of building products, PVC pipes and fittings and PVC compound products. Our sales are affected by the individual decisions of distributors and dealers on the levels of inventory they carry, their views on product demand, their financial condition and the manner in which they choose to manage inventory risk. A significant portion of our performance in this segment is driven by the activities in the residential construction and repair and remodeling markets in North America. Performance of our housing and infrastructure products businesses over time are generally reflective of the trends of building permits and housing starts in the New Residential Construction Survey by the U.S. Census Bureau and Repair and Remodeling Index (RRI) provided by the National Association of Home Builders ("NAHB") among others. Looking ahead, we expect that the approval of the Infrastructure Investment and Jobs Act in November 2021 will have a favorable impact on certain industries related to our Housing and Infrastructure Products segment in the future.
The following table presents annual historical housing starts per the U.S. Census Bureau and the 2022 outlook per the NAHB:
Period Single and Multi-family Housing Starts
(in thousands of units) % Change
2019 1,290 3%
2020 1,380 7%
2021 1,597 16%
2022 1,605
North American PVC facilities within the Performance and Essential Materials segment supply most of the PVC required for our building products and PVC pipes and fittings plants. Our raw materials for stone, roofing and accessories, windows, shutters and specialty tool products are externally purchased. PVC required for the PVC compounds plants is either internally sourced from our North American and Asian facilities within the Performance and Essential Materials segment or externally purchased based on the location of the plants. The remaining feedstocks required, including pigments, fillers, stabilizers and other ingredients, are purchased under short-term contracts based on prevailing market prices.
Factors that have caused volatility in our raw material prices and production processes in the past, and which may do so in the future include significant fluctuation in prices of these raw materials in response to, among other things, variable worldwide supply and demand across different industries, speculation in commodities futures, general economic or environmental conditions, labor costs, competition, import duties, tariffs, worldwide currency fluctuations, freight, regulatory costs, and product and process evolutions that impact demand for the same materials. Increasing raw material prices directly impact our cost of sales and our ability to maintain margins depends on implementing price increases in response to increasing raw material costs. The market for our products may or may not accept price increases, and as such, our future financial condition, results of operations or cash flows could be materially impacted.
Non-GAAP Financial Measures
The body of accounting principles generally accepted in the United States is commonly referred to as "GAAP." For this purpose, a non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows that (1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the registrant; or (2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. In this report, we disclose non-GAAP financial measures, primarily earnings before interest, taxes, depreciation and amortization ("EBITDA"). We define EBITDA as net income before interest expense, income taxes, depreciation and amortization. The non-GAAP financial measures described in this Form 10-K are not substitutes for the GAAP measures of earnings and cash flows.
EBITDA is included in this Form 10-K because our management considers it an important supplemental measure of our performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry, some of which present EBITDA when reporting their results. We regularly evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates by using EBITDA. In addition, we utilize EBITDA in evaluating acquisition targets. Management also believes that EBITDA is a useful tool for measuring our ability to meet our future debt service, capital expenditures and working capital requirements, and EBITDA is commonly used by us and our investors to measure our ability to service indebtedness. EBITDA is not a substitute for the GAAP measures of net income, income from operations and net cash provided by operating activities and is not necessarily a measure of our ability to fund our cash needs. In addition, it should be noted that companies calculate EBITDA differently and, therefore, EBITDA as presented for us may not be comparable to EBITDA reported by other companies. EBITDA has material limitations as a performance measure because it excludes interest expense, depreciation and amortization and income taxes. Reconciliations for EBITDA are included in the "Results of Operations" section below.
Significant Developments
COVID-19, Industry Conditions and Our Business
On March 11, 2020, the World Health Organization declared the ongoing COVID-19 outbreak a pandemic and recommended containment and mitigation measures worldwide. The pandemic has resulted in widespread adverse impacts on the global economy. We experienced significant disruptions in the second quarter of 2020 as the pandemic and its impact on the global economy spread through most of our markets. We were designated as an essential industry by many governments based on the nature of the products we manufacture. While demand for some of our products used in cleaning, packaging and medical applications and manufacturing continued to be firm, we expected lower demand for certain of our other products that led us to proactively temporarily idle production at several of our smaller non-integrated plants and reduce operating rates at others in the beginning of the second quarter of 2020. Since the middle of the second quarter of 2020, a general ease in government restrictions in many jurisdictions across the world has resulted in a gradual increase in demand for our products. As a result, all of our idled plants recommenced production. Except for the impact of the winter storm Uri and Hurricane Ida, operating rates have improved for most of our plants since the second half of 2020 due to continuing increase in demand for our products. Though the government restrictions across the world generally eased through the fourth quarter of 2021, there is considerable uncertainty regarding the extent to which COVID-19 will continue to spread and the extent and duration of governmental and other measures implemented to try to slow the spread of the virus. Factors that could impact the spread of COVID-19 include timing and logistics with respect to the distribution of vaccines globally, the efficacy of the available vaccines (including with respect to the more recent variants of COVID-19), vaccine hesitancy and the availability of other treatments. We continue to monitor the volatile environment and may reduce operating rates or idle production if the pandemic and its financial impacts persist or worsen. Considering the uncertain and volatile environment, we could continue to experience significant disruptions to our business operations in the near future.
Acquisitions
Hexion Global Epoxy Business
On November 24, 2021, Westlake, through one of its wholly-owned subsidiaries, entered into a Stock Purchase Agreement (the "Hexion Purchase Agreement") by and among Hexion Inc.

Summary
For the year ended December 31, 2021, net income attributable to Westlake Corporation was $2,015 million, or $15.58 per diluted share, on net sales of $11,778 million. This represents an increase in net income attributable to Westlake Corporation of $1,685 million, or $13.02 per diluted share, compared to 2020 net income attributable to Westlake Corporation of $330 million, or $2.56 per diluted share, on net sales of $7,504 million. Income from operations was $2,800 million for the year ended December 31, 2021 as compared to $429 million for the year ended December 31, 2020, an increase of $2,371 million. The increase in net income and income from operations was primarily due to significantly higher global sales prices and integrated margins for our major products due to the strengthening of demand for our products resulting from continued improvement in global economic activity from the severe impact of the COVID-19 pandemic in 2020, strong residential construction and repair and remodeling markets in North America and strong demand from the packaging and other consumer markets. Net income and income from operations for the year ended December 31, 2021 were positively impacted by higher margin contribution on ethylene produced by LACC. Net income and income from operations for the year ended December 31, 2021 was negatively impacted by higher feedstock costs, fuel costs and selling, general and administrative expense. The year ended December 31, 2020 net income included an income tax rate benefit of $95 million resulting from the carryback of federal net operating losses permitted by the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). Net sales increased by $4,274 million to $11,778 million in 2021 from $7,504 million in 2020, mainly due to higher sales prices for our major products as well as higher sales volumes for Housing and Infrastructure Products due to our acquisitions in 2021.
Net Sales. Net sales increased by $4,274 million, or 57%, to $11,778 million in 2021 from $7,504 million in 2020, primarily attributable to higher sales prices for our major products as well as higher sales volumes for Housing and Infrastructure Products due to our acquisitions in 2021. Average sales prices for 2021 increased by 51% as compared to 2020 due to the strong demand for our products resulting from continued improvement in global economic activity, strong residential construction, repair and remodeling markets in North America, and strong demand from the packaging and other consumer markets. Sales volumes increased by 6% in 2021 as compared to 2020, primarily due to the 2021 Acquisitions.
Gross Profit. Gross profit margin percentage increased to 30% in 2021 from 14% in 2020. The increase in gross profit margin was primarily due to higher sales prices and margins for our major products. Gross profit margin for the year ended December 31, 2021 was also positively impacted by the margin contributed from LACC's produced ethylene. Gross profit margin for the year ended December 31, 2021 was negatively impacted by higher feedstock and fuel costs.
Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by $102 million to $551 million in 2021 from $449 million in 2020. This increase was mainly due to higher employee compensation, selling and consulting expenses and the inclusion of expenses related to the 2021 Acquisitions.
Amortization of Intangibles. Amortization expense increased by $14 million to $123 million in 2021 from $109 million for 2020, primarily due to the amortization of intangibles associated with the 2021 Acquisitions.
Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-related costs were $21 million in 2021 as compared to $36 million in 2020. The restructuring, transaction and integration-related costs of $21 million for the year ended December 31, 2021 primarily consisted of costs associated with the 2021 Acquisitions. Restructuring, transaction and integration-related costs of $36 million in the year ended December 31, 2020 was primarily related to the closure of a non-integrated PVC plant located in Germany and included the $8 million write-off of certain assets and other expenses associated with the plant closure.
Interest Expense. Interest expense increased by $34 million to $176 million in 2021 from $142 million in 2020, primarily as a result of higher average debt outstanding in 2021 as compared to the year ended December 31, 2020 and the settlement of interest rate lock arrangements associated with the issuance of the Notes. See "Liquidity and Capital Resources-Debt" below and Note 11 to the consolidated financial statements included in this Form 10-K for further discussion of our indebtedness.
Other Income, Net. Other income, net of $53 million in 2021 was higher as compared to other income, net of $44 million in 2020. This increase was primarily due to higher expected return on pension plan assets.
Income Taxes. The effective income tax rate was an expense of 23% in 2021 as compared to a benefit of 13% in 2020. The change in effective tax rate in 2021 as compared to 2020 was primarily due to the income tax rate benefit in the year ended December 31, 2020 resulting from the carryback of federal net operating loss to taxable years that were taxed at the U.S. corporate tax rate of 35% as permitted under the CARES Act, partially offset by the reduction in the Section 199 domestic manufacturing deduction as a result of the net operating loss carryback.
Performance and Essential Materials Segment
Net Sales. Net sales for the Performance and Essential Materials segment increased by $3,205 million, or 59%, to $8,670 million in 2021 from $5,465 million in 2020. Average sales prices for the Performance and Essential Materials segment increased by 58% in 2021 as compared to 2020. The higher performance materials sales prices were due to higher polyethylene and PVC resin sales prices. The higher essential materials sales prices were primarily driven by the higher prices for caustic due to improved global economic activity. Sales volumes for the Performance and Essential Materials segment remained relatively consistent in 2021 as compared to 2020.
Income from Operations. Income from operations for the Performance and Essential Materials segment increased by $2,318 million to $2,549 million in 2021 from $231 million in 2020. This increase in income from operations was primarily due to higher sales prices and margins for polyethylene, PVC resin and caustic soda, mainly resulting from the continued improvement in global economic activity from the severe impact of the COVID-19 pandemic in 2020. The increase in income from operations as compared to the prior year was negatively impacted by higher feedstock and fuel costs. Income from operations for the year ended December 31, 2021 was also impacted by Winter Storm Uri and Hurricane Ida, while income from operations for the year ended December 31, 2020 was negatively impacted by the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.
Housing and Infrastructure Products Segment
Net Sales. Net sales for the Housing and Infrastructure Products segment increased by $1,069 million, or 52%, to $3,108 million in 2021 from $2,039 million in 2020. In addition to the net sales from the businesses we acquired in the second half of 2021, the increase in net sales was also driven by higher sales prices for our major products in the housing and infrastructure businesses. Average sales prices increased by 33% from 2020 to due to strong demand for our major products in the residential construction and repair and remodeling markets. Sales volumes for the Housing and Infrastructure Products segment increased by 19% in 2021 as compared to 2020 due to strong demand as well as the businesses we acquired in the second half of 2021.
Income from Operations. Income from operations for the Housing and Infrastructure Products segment increased by $100 million to $356 million in 2021 from $256 million in 2020. The increase in income from operations was primarily due to significantly higher sales prices and margins driven by robust housing construction and remodeling activity resulting from the continued economic recovery from the COVID-19 pandemic. Additionally, 2021 experienced higher energy costs as well as the impacts from Winter Storm Uri and Hurricane Ida, while income from operations for the year ended December 31, 2020 was negatively impacted by the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.
2020 Compared with 2019
Summary
For the year ended December 31, 2020, net income attributable to Westlake Corporation was $330 million, or $2.56 per diluted share, on net sales of $7,504 million. This represents a decrease in net income attributable to Westlake Corporation of $91 million, or $0.69 per diluted share, compared to 2019 net income attributable to Westlake Corporation of $421 million, or $3.25 per diluted share, on net sales of $8,118 million. Net income for the year ended December 31, 2020 decreased as compared to the prior year primarily due to lower global sales prices for several of our major products, including caustic soda, and lower sales volumes for caustic soda resulting from the impact of the COVID-19 pandemic and lower crude oil prices. Net income for 2020 was also impacted by the shutdowns of our Lake Charles facilities in the second half of 2020 due to Hurricanes Laura and Delta, which resulted in lower plant operating rates, higher maintenance expense and lower production for many of our major products. In addition, in 2020 we had a higher interest expense related to higher average borrowings. These decreases were partially offset by the income tax rate benefit of $95 million, or $0.74 per diluted share, resulting from the carryback of federal net operating losses permitted by the CARES Act, higher sales volumes for housing and infrastructure products, higher contributions from our ethylene joint venture LACC, LLC ("LACC") and lower fuel costs and selling, general and administrative expenses. Income from operations was $429 million for the year ended December 31, 2020 as compared to $656 million for the year ended December 31, 2019, a decrease of $227 million. The decrease in income from operations was primarily due to lower global sales prices for our major products, lower sales volume for caustic soda, lower operating rates and higher maintenance expense due to Hurricanes Laura and Delta. The decreases were partially offset by higher sales volumes for housing and infrastructure products and higher contributions from LACC, lower fuel costs and selling, general and administrative costs. Net sales decreased by $614 million to $7,504 million in 2020 from $8,118 million in 2019, mainly due to lower sales prices and volumes for several of our major products, including caustic soda, partially offset by higher sales volumes for housing and infrastructure products in the second half of the year ended December 31, 2020.
Net Sales. Net sales decreased by $614 million, or 8%, to $7,504 million in 2020 from $8,118 million in 2019, primarily attributable to lower sales prices and volumes for several of our major products, including caustic soda, partially offset by higher sales volumes for housing and infrastructure products. Average sales prices for 2020 decreased by 4% as compared to 2019 due to slower global economic activity as a result of the COVID-19 pandemic and lower crude oil prices. Sales volumes decreased by 3% in 2020 as compared to 2019.
Gross Profit. Gross profit margin percentage decreased to 14% in 2020 from 16% in 2019. The gross profit margin decreased primarily due to lower global sales prices for several of our major products and lower sales volumes for caustic soda resulting from the impact of the COVID-19 pandemic and lower crude oil prices. Gross profit margin was also impacted by the shutdown of our Lake Charles facilities in the second half of 2020 due to Hurricanes Laura and Delta, which resulted in lower plant operating rates, higher maintenance expense and lower production for many of our major products. These decreases were partially offset by higher sales volumes for housing and infrastructure products and lower fuel costs.
Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $9 million to $449 million in 2020 from $458 million in 2019. This decrease was mainly due to lower employee compensation and selling expenses.
Amortization of Intangibles. Amortization expense for 2020 was $109 million, which was comparable to $109 million for 2019.
Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-related costs were $36 million in 2020 as compared to $37 million in 2019. The restructuring, transaction and integration-related costs for 2020 primarily related to the closure of a non-integrated PVC plant located in Germany and included the $8 million write-off of certain assets and other expenses associated with the plant closure. The restructuring, transaction and integration-related costs for 2019 primarily consisted of restructuring expenses of $26 million and acquisition costs.
Interest Expense. Interest expense increased by $18 million to $142 million in 2020 from $124 million in 2019, primarily as a result of higher average debt outstanding in 2020 as compared to 2019. The higher average debt balance in 2020 was primarily due to the borrowing of $1 billion under our revolving credit facility in March 2020 out of an abundance of caution (which we fully repaid in June 2020), the issuance of the €700 million aggregate principal amount of 1.625% 2029 Senior Notes in July 2019, which were outstanding for the full calendar year in 2020 (as compared to less than half a year in 2019), and the issuance of the $300 million aggregate principal amount of 3.375% 2030 Senior Notes in June 2020 and lower interest capitalization due to lower activity with respect to capital expenditure projects during 2020 as compared to the prior year, partially offset by the purchase in lieu of redemption of the 6 ½% 2029 GO Zone Bonds, the 6 ½% 2035 GO Zone Bonds and the 6 ½% 2035 IKE Zone Bonds. See "Liquidity and Capital Resources-Debt" below and Note 11 to the consolidated financial statements included in this Form 10-K for further discussion of our indebtedness.
Other Income, Net. Other income, net of $44 million in 2020 was higher as compared to other income, net of $38 million in 2019. This increase was primarily due to higher expected return on pension plan assets.
Income Taxes. The effective income tax rate was a benefit of 13% in 2020 as compared to an expense of 19% in 2019. The change in effective tax rate in 2020 as compared to the prior year was primarily due to the income tax rate benefit resulting from the carryback of federal net operating loss to taxable years that were taxed at the U.S. corporate tax rate of 35% as permitted under the CARES Act, partially offset by the reduction in the Section 199 domestic manufacturing deduction as a result of the net operating loss carryback.
Performance and Essential Materials Segment
Net Sales. Net sales for the Performance and Essential Materials segment decreased by $719 million, or 12%, to $5,465 million in 2020 from $6,184 million in 2019. Average sales prices for the Performance and Essential Materials segment decreased by 6% in 2020, as compared to 2019. The lower performance materials sales prices were due to lower polyethylene prices as a result of increased production from new industry capacity and lower PVC resin sales prices due to slower global economic activity as a result of the COVID-19 pandemic. The lower essential materials sales prices were driven by lower caustic soda prices. Average sales volumes decreased by 6% in 2020 as compared to 2019 due to the slower global economic activity as a result of the COVID-19 pandemic. Lower performance materials global sales volumes were due to lower polyethylene and PVC resin sales volumes and lower essential materials sales volumes were driven by lower caustic soda sales volume.
Income from Operations. Income from operations for the Performance and Essential Materials segment decreased by $338 million to $231 million in 2020 from $569 million in 2019. This decrease in income from operations was primarily due to lower caustic soda and PVC resin sales prices and lower PVC resin and polyethylene sales volumes, partially offset by lower purchased ethylene, ethane feedstock and fuel costs. Trading activity in 2020 resulted in a gain of approximately $4 million as compared to a loss of $26 million in 2019.
Housing and Infrastructure Products Segment
Net Sales. Net sales for the Housing and Infrastructure Products segment increased by $105 million, or 5%, to $2,039 million in 2020 from $1,934 million in 2019. Sales volumes for the Housing and Infrastructure Products segment increased by 5% in 2020 as compared to 2019, primarily due to higher demand for our major products in the residential construction and repair and remodeling markets, partially offset by lower infrastructure products sales due to the impact of the COVID-19 pandemic.
Income from Operations. Income from operations for the Housing and Infrastructure Products segment increased by $120 million to $256 million in 2020 from $136 million in 2019. The increase in income from operations was primarily due to higher sales volumes and prices for our major housing products and lower feedstock costs partially offset by lower sales for infrastructure products. The income from operations for the year ended December 31, 2020 was also negatively impacted by the onset of the COVID-19 pandemic and Hurricanes Laura and Delta.
Cash Flows
Operating Activities
Operating activities provided cash of $2,394 million in 2021, as compared to cash provided by operating activities of $1,297 million in 2020. The $1,097 million increase in cash flows from operating activities was mainly due to the increase in income from operations, which was partially offset by working capital changes and an unfavorable change related to the turnaround at OpCo's Petro 2 facility and other turnaround activities. Changes in components of working capital, which we define for purposes of this cash flow discussion as accounts receivable, inventories, prepaid expenses and other current assets, less accounts payable and accrued and other liabilities, used cash of $383 million in 2021, as compared to $17 million of cash used in 2020, an unfavorable change of $366 million. The majority of the unfavorable changes in 2021 were driven by higher accounts receivable and higher inventories, partially offset by higher accounts payable and accrued and other liabilities. The unfavorable change in accounts receivable was primarily driven by higher sales prices resulting in higher trade customer balances. The higher inventories, accounts payable and accrued and other liabilities in 2021 were primarily driven by higher inventory cost and an increase in operating activities, as compared to 2020.
Operating activities provided cash of $1,297 million in 2020 as compared to cash provided by operating activities of $1,301 million in 2019. The changes in cash flows from operating activities in 2020, as compared to 2019, were mainly driven by the decrease in income from operations, the income tax refund of $188 million under the CARES Act and working capital changes. Changes in components of working capital, which we define for purposes of this cash flow discussion as accounts receivable, inventories, prepaid expenses and other current assets, less accounts payable and accrued and other liabilities used cash of $17 million in 2020, as compared to $68 million of cash provided in 2019, an unfavorable change of $85 million. Unfavorable changes in working capital were due to a change in accounts receivable, which was driven by higher sales in the fourth quarter of 2020 and the expected additional income tax refund resulting from the CARES Act, as discussed previously. Favorable changes in working capital were due to lower inventories and higher accounts payable and accrued liabilities, primarily driven by the changes in inventory levels and operating activities.
Investing Activities
Net cash used for investing activities during 2021 was $3,213 million as compared to net cash used of $509 million in 2020. The increase in investing activities in 2021 was primarily due to the acquisitions of Boral, LASCO and Dimex for $2,554 million in the aggregate, net of cash acquired. Capital expenditures were $658 million in 2021 compared to $525 million in 2020. The higher capital expenditures in 2021 were primarily associated with the turnaround at OpCo's Petro 2 facility. Capital expenditures in 2021 and 2020 were primarily related to projects to improve production capacity or reduce costs, maintenance and safety projects and environmental projects at our various facilities. During 2021, we contributed $22 million to LACC and $2 million to an unconsolidated investee compared to a net return of investment of $40 million from LACC in 2020.
Net cash used for investing activities during 2020 was $509 million as compared to net cash used of $1,954 million in 2019. Capital expenditures were $525 million in 2020 compared to $787 million in 2019. The decrease in capital expenditures was primarily due to fewer expansion projects in 2020, as compared to 2019. Capital expenditures in 2020 were primarily related to projects to improve production capacity or reduce costs, maintenance and safety projects and environmental projects at our various facilities. In 2020, we received $44 million from our joint venture, LACC, representing a return of investment and we contributed $4 million. The Company's contribution to unconsolidated subsidiaries in 2020 was primarily comprised of $14 million towards our investment in RS Cogen. Investing activities in 2019 were primarily due to acquisitions for $314 million, net of cash acquired, the purchase of the additional 34.8% interest in LACC for $817 million in November 2019 and payment of $45 million to fund the construction costs of LACC. Capital expenditures in 2019 included certain announced expansion projects as well as projects to improve production capacity or reduce costs, maintenance and safety and environmental projects at our various facilities.
Financing Activities
Net cash provided by financing activities during 2021 was $1,437 million as compared to net cash used of $216 million in 2020. The activities during 2021 were primarily related to the registered public offering of $300 million aggregate principal amount of the 0.875% 2024 Senior Notes, $350 million aggregate principal amount of the 2.875% 2041 Senior Notes, $600 million aggregate principal amount of the 3.125% 2051 Senior Notes and $450 million aggregate principal amount of the 3.375% 2061 Senior Notes and the payment of debt issuance costs of $18 million related to the Notes. The remaining activities in 2021 were primarily related to the $145 million payment of cash dividends, the $48 million payment of cash distributions to noncontrolling interests and repurchases of our common stock for an aggregate purchase price of $30 million.
Net cash used for financing activities during 2020 was $216 million as compared to net cash provided of $630 million in 2019. In 2020, out of abundance of caution, we borrowed $1,000 million under our revolving credit facility, which we subsequently fully repaid in June 2020. In 2020, we completed the registered public offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes and we purchased in lieu of optional redemption the $100 million 6 ½% 2029 GO Zone Senior Notes, the $89 million 6 ½% 2035 GO Zone Senior Notes and the $65 million 6 ½% 2035 IKE Zone Senior Notes. The remaining activities in 2020 were primarily related to the $137 million payment of cash dividends, the $55 million payment of cash distributions to noncontrolling interests, repurchases of common stock of $54 million and repayment of short-term notes payable of $17 million. In 2019, we received proceeds of $784 million from the issuance of the 1.625% 2029 Senior Notes and $63 million from the issuance of Westlake Partners common units. The remaining activities in 2019 were primarily related to the $132 million payment of cash dividends, the $50 million payment of cash distributions to noncontrolling interests and repurchases of common stock for an aggregate purchase price of $30 million.
Liquidity and Capital Resources
Liquidity and Financing Arrangements
Our principal sources of liquidity are from cash and cash equivalents, cash from operations, short-term borrowings under the Credit Agreement and our long-term financing.
In November 2014, our Board of Directors authorized a $250 million stock repurchase program (the "2014 Program"). In November 2015, our Board of Directors approved the expansion of the 2014 Program by an additional $150 million. In August 2018, our Board of Directors approved the further expansion of the existing 2014 Program by an additional $150 million. As of December 31, 2021, we had repurchased 7,431,520 shares of our common stock for an aggregate purchase price of approximately $449 million under the 2014 Program. During the year ended December 31, 2021, 355,800 shares of our common stock were repurchased for an aggregate purchase price of $30 million under the 2014 Program. Purchases under the 2014 Program may be made either through the open market or in privately negotiated transactions. Decisions regarding the amount and the timing of purchases under the 2014 Program will be influenced by our cash on hand, our cash flow from operations, general market conditions and other factors. The 2014 Program may be discontinued by our Board of Directors at any time.
On October 4, 2018, Westlake Partners and Westlake Partners GP, the general partner of Westlake Partners, entered into an Equity Distribution Agreement with UBS Securities LLC, Barclays Capital Inc., Citigroup Global Markets Inc., Deutsche Bank Securities Inc., RBC Capital Markets, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC to offer and sell Westlake Partners common units, from time to time, up to an aggregate offering amount of $50 million. This Equity Distribution Agreement was amended on February 28, 2020 to reference a new shelf registration for utilization under this agreement. No common units have been issued under this program in 2019, 2020 or 2021.
We believe that our sources of liquidity as described above are adequate to fund our normal operations and ongoing capital expenditures. Funding of any potential large expansions such as our recent Acquisitions or potential future acquisitions or the repayment of debt may likely necessitate, and therefore depend on our ability to obtain, additional financing in the future. We may not be able to access additional liquidity at cost effective interest rates due to the volatility of the commercial credit markets.
On August 19, 2021, we completed the registered public offering of the Notes. See "Liquidity and Capital Resources-Debt" below for more information.
Cash and Cash Equivalents
As of December 31, 2021, our cash and cash equivalents totaled $1,908 million. In addition, we have the Credit Agreement available to supplement cash if needed, as described under "Debt" below.
Debt
As of December 31, 2021, our indebtedness totaled $5,180 million. See Note 11 to the consolidated financial statements appearing elsewhere in this Form 10-K for a discussion of our long-term indebtedness. Defined terms used in this section have the definitions assigned to such terms in Note 11 to the consolidated financial statements included in Item 8 of this Form 10-K.
Our ability to make payments on our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future, which is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. Based on our current level of operations and unless we were to undertake a new expansion or large acquisition, we believe our cash flows from operations, available cash and available borrowings under the Credit Agreement will be adequate to meet our normal operating needs for the foreseeable future.
Credit Agreement
On July 24, 2018, we entered into a new $1 billion revolving credit facility that is scheduled to mature on July 24, 2023 (the "Credit Agreement"). The Credit Agreement bears interest at either (a) LIBOR plus a spread ranging from 1.00% to 1.75% or (b) Alternate Base Rate plus a spread ranging from 0.00% to 0.75% in each case depending on the credit rating of the Company. As of December 31, 2021, we had no borrowings outstanding under the Credit Agreement. As of December 31, 2021, we had no outstanding letters of credit and had borrowing availability of $1 billion under the Credit Agreement. The Credit Agreement contains certain affirmative and negative covenants, including a quarterly total leverage ratio financial maintenance covenant. As of December 31, 2021, we were in compliance with the total leverage ratio financial maintenance covenant.
The Credit Agreement also contains certain events of default and if and for so long as certain events of default have occurred and are continuing, any overdue amounts outstanding under the Credit Agreement will accrue interest at an increased rate, the lenders can terminate their commitments thereunder and payments of any outstanding amounts could be accelerated by the lenders. None of our subsidiaries are required to guarantee our obligations under the Credit Agreement.
The Credit Agreement includes a $150 million sub-limit for letters of credit, and any outstanding letters of credit will be deducted from availability under the facility. The Credit Agreement also provides for a discretionary $50 million commitment for swingline loans to be provided on a same-day basis. We may also increase the size of the facility, in increments of at least $25 million, up to a maximum of $500 million, subject to certain conditions and if certain lenders agree to commit to such an increase.

Westlake Chemical Partners LP Credit Arrangements
Our subsidiary, Westlake Chemical Finance Corporation, is the lender party to a $600 million revolving credit facility with Westlake Chemical Partners LP ("Westlake Partners"), originally entered into on April 29, 2015 and amended in August and December 2017. In addition, on March 19, 2020, Westlake Partners and Westlake Chemical Finance Corporation entered into an amendment to the revolving credit facility, to extend the maturity date to March 19, 2023 and add a phase-out provision for LIBOR, which is to be replaced by an alternate benchmark rate. Borrowings under the revolving credit facility bear interest at LIBOR plus a spread ranging from 2.0% to 3.0% (depending on Westlake Partners' consolidated leverage ratio), payable quarterly. Westlake Partners may pay all or a portion of the interest on any borrowings in kind, in which case any such amounts would be added to the principal amount of the loan. As of December 31, 2021, outstanding borrowings under the revolving credit facility totaled $377 million and bore interest at the LIBOR rate plus 2.0%.
Our subsidiary, Westlake Polymers LLC, is the administrative agent to a $600 million revolving credit facility with OpCo. The revolving credit facility is scheduled to mature in September 2023. As of December 31, 2021, outstanding borrowings under the credit facility totaled $23 million and bore interest at the LIBOR rate plus 2.0%, which is accrued in arrears quarterly.
We consolidate Westlake Partners and OpCo for financial reporting purposes as we have a controlling financial interest. As such, the revolving credit facilities described above between our subsidiaries and Westlake Partners and OpCo are eliminated upon consolidation.
Contractual and Other Obligations
The Company's material cash requirements for contractual and other obligations in the near term (next 12 months) and the long term period (2023 and thereafter) include long-term debt, interest payments, operating leases, pension benefits funding, post-retirement healthcare benefits, purchase obligations and asset retirement obligations.
Debt Obligations and Interest Payments. As of December 31, 2021, we had debt obligations of $269 million and related interest expense of $165 million due within the near term, and debt obligations of $5,014 million and related interest expense of $3,001 million due over the long-term period, respectively. Maturities of our debt consist of $269 million in 2022, $300 million in 2024, and $759 million in 2026. There are no other scheduled maturities of debt in 2022 through 2026. See Note 11, "Long-Term Debt," in the Notes to Consolidated Financial Statements in Item 8 for further information on our debt obligations and the expected timing of future principal and interest payments.
Operating leases. As of December 31, 2021, there was $119 million in operating lease obligations due within the near term, and $553 million due over the long-term period, respectively. See Note 7, "Leases," in the Notes to Consolidated Financial Statements in Item 8 for further detail of our obligations and the timing of expected future payments.
Pension Benefits Funding and Post-retirement Healthcare Benefits. Pension benefits funding obligations due within the near term were $6 million while post-retirement healthcare benefit payment obligations due within the near term were $8 million as of December 31, 2021. As of December 31, 2021, we had $77 million and $53 million of pension benefit funding and post-retirement healthcare benefit obligations due over the long-term period, respectively. The estimate of the timing of future payments under our defined benefit pension plans which cover certain eligible employees in the United States and non-U.S. countries and our post-retirement healthcare benefits to the employees of certain subsidiaries who meet certain minimum age and service requirements involves the use of certain assumptions, including retirement ages and payout periods. See Note 14, "Employee Benefits," in the Notes to Consolidated Financial Statements in Item 8 for further information on our obligations and the timing of expected future payments.
Purchase Obligations. Purchase obligations include agreements to purchase goods and services that are enforceable and legally binding and that specify all significant terms, including a minimum quantity and price. We are party to various obligations to purchase goods and services, including commitments to purchase various feedstock, utilities, nitrogen, oxygen, product storage, pipeline usage and logistic support, in each case in the ordinary course of our business, as well as various purchase commitments for our capital projects. As of December 31, 2021, we had $1,890 million of enforceable and legally binding purchase commitments due within the near term, and $5,220 million due over the long-term period.
Asset Retirement Obligations. As of December 31, 2021, we had an immaterial amount of asset retirement obligations due within the near term, and $61 million due over the long-term period. Asset retirement obligations includes the estimated costs and timing of payments to satisfy our recognized asset retirement obligations. We recognize asset retirement obligations in the period in which the liability becomes probable and reasonably estimable. Initially, the asset retirement obligation is recorded at fair value and capitalized as a component of the carrying value of the long-lived asset to which the obligation relates. See Note 1, "Description of Business and Significant Accounting Policies," in the Notes to Consolidated Financial Statements in Item 8 for further detail of our asset retirement obligations.
Critical Accounting Policies and Estimates
Critical accounting policies are those that are important to our financial condition and require management's most difficult, subjective or complex judgments. Different amounts would be reported under different operating conditions or under alternative assumptions. We have evaluated the accounting policies used in the preparation of the accompanying consolidated financial statements and related notes and believe those policies are reasonable and appropriate. Our significant accounting policies are summarized in Note 1 to the consolidated financial statements appearing elsewhere in this Form 10-K.
Critical accounting estimates are those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operation. Our more critical accounting estimates include those related to long-lived assets, fair value estimates, accruals for long-term employee benefits, accounts receivable, income taxes and environmental and legal obligations. Inherent in such estimates are certain key assumptions. We periodically update the estimates used in the preparation of the financial statements based on our latest assessment of the current and projected business and general economic environment. We believe the following to be our most critical accounting estimates required for the preparation of our financial statements.
Long-Lived Assets. Key estimates related to long-lived assets include useful lives, recoverability of carrying values and existence of any retirement obligations. Such estimates could be significantly modified. The carrying values of long-lived assets could be impaired by significant changes or projected changes in supply and demand fundamentals (which would have a negative impact on operating rates or margins), new technological developments, new competitors with significant raw material or other cost advantages, adverse changes associated with the United States and world economies, the cyclical nature of the chemical and refining industries and uncertainties associated with governmental actions.
We evaluate long-lived assets for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, including when negative conditions such as significant current or projected operating losses exist. Our judgments regarding the existence of impairment indicators are based on legal factors, market conditions and the operational performance of our businesses. Actual impairment losses incurred could vary significantly from amounts estimated. Long-lived assets assessed for impairment are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Additionally, future events could cause us to conclude that impairment indicators exist and that associated long-lived assets of our businesses are impaired. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations.
The estimated useful lives of long-lived assets range from one to 40 years. Depreciation and amortization of these assets, including amortization of deferred turnaround costs, under the straight-line method over their estimated useful lives totaled $840 million, $773 million and $713 million in 2021, 2020 and 2019, respectively. If the useful lives of the assets were found to be shorter than originally estimated, depreciation or amortization charges would be accelerated.
We defer the costs of planned major maintenance activities, or turnarounds, and amortize the costs over the period until the next planned turnaround of the affected unit. Total costs deferred on turnarounds were $215 million, $24 million and $40 million in 2021, 2020 and 2019, respectively. As of December 31, 2021, deferred turnaround costs, net of accumulated amortization, totaled $261 million. Amortization in 2021, 2020 and 2019 of deferred turnaround costs was $56 million, $48 million and $55 million, respectively. Expensing turnaround costs as incurred would likely result in greater variability of our quarterly operating results and would adversely affect our financial position and results of operations.
Additional information concerning long-lived assets and related depreciation and amortization appears in Notes 6 and 8 to the consolidated financial statements appearing elsewhere in this Form 10-K.
Fair Value Estimates. We develop estimates of fair value to allocate the purchase price paid to acquire a business to the assets acquired and liabilities assumed in an acquisition, to assess impairment of long-lived assets, goodwill and intangible assets and to record marketable securities and pension plan assets. We use all available information to make these fair value determinations, including the engagement of third-party consultants. At December 31, 2021, our recorded goodwill was $2,024 million. In addition, we record all pension plan assets and certain marketable securities at fair value. The fair value of these items is determined by quoted market prices or from observable market-based inputs. See Note 16 to the consolidated financial statements appearing elsewhere in this Form 10-K for more information.
Business Combinations and Intangible Assets Including Goodwill. We account for business combinations using the acquisition method of accounting, and accordingly, the assets and liabilities of the acquired business are recorded at their fair values at the date of acquisition. The excess of the purchase price over the estimated fair value is recorded as goodwill. Any changes in the estimated fair values of the net assets recorded for acquisitions prior to the finalization of more detailed analysis, but not to exceed one year from the date of acquisition, will change the amount of the purchase price allocable to goodwill. Any subsequent changes to any purchase price allocations that are material to our consolidated financial results will be adjusted in the same period's financial statements, including the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. All acquisition costs are expensed as incurred and in-process research and development costs are recorded at fair value as an indefinite-lived intangible asset and assessed for impairment thereafter until completion, at which point the asset is amortized over its expected useful life. Separately recognized transactions associated with business combinations are generally expensed subsequent to the acquisition date. The application of business combination accounting requires the use of significant estimates and assumptions. Our estimates of fair value are based upon assumptions we believe to be reasonable, but which are inherently uncertain and unpredictable. The fair value of the customer relationships acquired are estimated by management through a discounted cash flow model using the multi-period excess earnings methodology, which involves the use of significant estimates and assumptions related to revenue growth rates, operating margins, discount rates, and customer attrition rates, among other items. The fair value of the technology and trade names acquired is estimated by management through a discounted cash flow model using the relief from royalty methodology, which involves the use of significant estimates and assumptions related to revenue growth rates, and discount rates.
Goodwill is evaluated for impairment when events or changes in circumstances indicate the fair value of a reporting unit with goodwill has been reduced below its carrying value, and otherwise at least annually. We have historically operated in two principal operating segments, Vinyls and Olefins. In the fourth quarter of 2021, we reorganized our business into two principal operating segments, Performance and Essential Materials and Housing and Infrastructure Products. As part of the reorganization, we assessed and re-defined reporting units effective as of the beginning of the fourth quarter of 2021, including reallocation of goodwill on a relative fair value basis as applicable to affected reporting units. Goodwill impairment analyses were performed as of the effective reorganization date both before and after the reorganization. We will perform our annual impairment assessment for both the Performance and Essential Materials and Housing and Infrastructure Products reporting units in October each year. We may elect to perform an optional qualitative assessment to determine whether a quantitative impairment analysis is required. The qualitative assessment considers factors such as macroeconomic conditions, industry and market considerations, cost factors related to raw materials and labor, current and projected financial performance, changes in management or strategy, and market capitalization. Alternatively, we may unconditionally elect to bypass the qualitative assessment and perform a quantitative goodwill impairment assessment in any period.
We elected to perform the quantitative assessment for both of our segments' reporting units during 2021. The quantitative analysis compares a reporting unit's fair value to its carrying amount to determine whether goodwill is impaired. The fair values of the reporting units are calculated using both a discounted cash flow methodology and a market value methodology. The discounted cash flow projections are based on a forecast to reflect the cyclicality of the business. The forecast is based on historical results and estimates by management, including its strategic and operational plans, and financial performance of the market. The future cash flows are discounted to present value using an applicable discount rate. The significant assumptions used in determining the fair value of the reporting unit using the market value methodology include the determination of appropriate market comparables and the estimated multiples of EBITDA a willing buyer is likely to pay. Even if the fair values of the reporting units decreased by 10% from the fair values determined in the most recent quantitative tests performed during 2021, the carrying values of the reporting units would not have exceeded their fair values. See Item 1A, "Risk Factors-If our goodwill, indefinite-lived intangible assets or other intangible assets become impaired in the future, we may be required to record non-cash charges to earnings, which could be significant."
The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.
Long-Term Employee Benefit Costs. Our costs for long-term employee benefits, particularly pension and postretirement medical and life benefits, are incurred over long periods of time and involve many uncertainties over those periods. The net periodic benefit cost attributable to current periods is based on several assumptions about such future uncertainties and is sensitive to changes in those assumptions. It is our responsibility, often with the assistance of independent experts, to select assumptions that represent the best estimates of those uncertainties. It is also our responsibility to review those assumptions periodically and, if necessary, adjust the assumptions to reflect changes in economic or other factors.
Accounting for employee retirement plans involves estimating the cost of benefits that are to be provided in the future and attempting to match, for each employee, that estimated cost to the period worked. To accomplish this, we rely extensively on advice from actuaries, and we make assumptions about inflation, investment returns, mortality, employee turnover and discount rates that ultimately impact amounts recorded. Changes in these assumptions may result in different expense and liability amounts. One of the more significant assumptions relates to the discount rate for measuring benefit obligations. At December 31, 2021, the projected pension benefit obligations for U.S. and non-U.S. plans were calculated using assumed weighted average discount rates of 2.6% and 1.4%, respectively. The discount rates were determined using a benchmark pension discount curve and applying spot rates from the curve to each year of expected benefit payments to determine the appropriate discount rate. As a result of the funding relief provided by the enactment of the Bipartisan Budget Act of 2015, no minimum funding requirements are expected during 2022 for the U.S. pension plans. Additional information on the 2022 funding requirements and key assumptions underlying these benefit costs appear in Note 14 to the consolidated financial statements appearing elsewhere in this Form 10-K.
The following table reflects the sensitivity of the benefit obligation of our pension plans to changes in the actuarial assumptions:
U.S. Plans Non-U.S. Plans
(dollars in millions)
Projected benefit obligation, end of year $ 673 $ 152
Discount rate increases by 100 basis points (72) (21)
Discount rate decreases by 100 basis points 87 26
A one-percentage point increase or decrease in assumed healthcare trend rates would not have a significant effect on the amounts reported for the healthcare plans.
While we believe that the amounts recorded in the consolidated financial statements appearing elsewhere in this Form 10-K related to these retirement plans are based on the best estimates and judgments available, the actual outcomes could differ from these estimates.
Income Taxes. We utilize the liability method of accounting for income taxes. Under the liability method, deferred tax assets or liabilities are recorded based upon temporary differences between the tax basis of assets and liabilities and their carrying values for financial reporting purposes. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities during the period. Valuation allowances are recorded against deferred tax assets when it is considered more likely than not that the deferred tax assets will not be realized. Additional information on income taxes appears in Note 17 to the consolidated financial statements appearing elsewhere in this Form 10-K.
Environmental and Legal Obligations. We consult with various professionals to assist us in making estimates relating to environmental costs and legal proceedings. We accrue an expense when we determine that it is probable that a liability has been incurred and the amount is reasonably estimable. While we believe that the amounts recorded in the accompanying consolidated financial statements related to these contingencies are based on the best estimates and judgments available, the actual outcomes could differ from our estimates. Additional information about certain legal proceedings and environmental matters appears in Note 22 to the consolidated financial statements appearing elsewhere in this Form 10-K.
Asset Retirement Obligations. We recognize asset retirement obligations in the period in which the liability becomes probable and reasonably estimable. Initially, the asset retirement obligation is recorded at fair value and capitalized as a component of the carrying value of the long-lived asset to which the obligation relates. The liability is recorded at its future value each period, and the capitalized cost is depreciated over the estimated useful life of the related asset. Upon settlement of the liability, a gain or loss is recorded. We have conditional asset retirement obligations for the removal and disposal of hazardous materials from certain of our manufacturing facilities. Additional information on asset retirement obligations appears in Note 1, under Asset Retirement Obligations, to the consolidated financial statements appearing elsewhere in this Form 10-K.
We also have conditional asset retirement obligations that have not been recognized because the fair values of the conditional legal obligations cannot be measured due to the indeterminate settlement date of the obligations. Settlements of the unrecognized conditional asset retirement obligations are not expected to have a material adverse effect on our financial condition, results of operations or cash flows in any individual reporting period.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Commodity Price Risk
A substantial portion of our products and raw materials are commodities whose prices fluctuate as market supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to fluctuate with changes in the business cycle. We try to protect against such instability through various business strategies. Our strategies include ethylene product feedstock flexibility and moving downstream into our other products where pricing is more stable. We use derivative instruments in certain instances to reduce price volatility risk on feedstocks and products. Based on our open derivative positions on ethane at December 31, 2021, a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before income taxes by $17 million and a hypothetical $0.10 increase in the price of a million British thermal units of natural gas would have decreased our income before income taxes by $1 million.
Interest Rate Risk
We are exposed to interest rate risk with respect to fixed and variable rate debt. At December 31, 2021, we had $5,263 million aggregate principal amount of fixed rate debt. We are subject to the risk of higher interest cost if and when this debt is refinanced. If interest rates were 1.0% higher at the time of refinancing, our annual interest expense would increase by approximately $53 million. Also, at December 31, 2021, we had $20 million principal amount of variable rate debt outstanding, which primarily represents the tax-exempt waste disposal revenue bonds. We do not currently hedge our variable interest rate debt, but we may do so in the future. The average variable interest rate for our variable rate debt of $20 million as of December 31, 2021 was 0.17%. A hypothetical 100 basis point increase in the average interest rate on our variable rate debt would not result in a material change in the interest expense. During June and July 2021, in order to manage the interest rate risk associated with potential borrowings, we entered into treasury lock agreements to fix the treasury yield component of the interest cost. These agreements settled in August 2021 on the issuance of the Notes.
LIBOR is used as a reference rate for borrowings under our revolving line of credit. The phase-out of LIBOR commenced at the end of 2021 and is set to conclude by June 30, 2023. We do not expect the impact of the LIBOR phase out to be material as we did not have any external LIBOR-based borrowings outstanding at December 31, 2021.
Foreign Currency Exchange Rate Risk
We are exposed to foreign currency exchange rate risk associated with our international operations. However, the effect of fluctuations in foreign currency exchange rates caused by our international operations has not had a material impact on our overall operating results. We may engage in activities to mitigate our exposure to foreign currency exchange risk in certain instances through the use of currency exchange derivative instruments, including forward exchange contracts, cross-currency swaps or spot purchases. A forward exchange contract obligates us to exchange predetermined amounts of specified currencies at a stated exchange rate on a stated date. A cross-currency swap obligates us to make periodic payments in the local currency and receive periodic payments in our functional currency based on the notional amount of the instrument. In January 2018, we entered into foreign exchange hedging contracts designated as net investment hedges with an aggregate notional value of €220 million designed to reduce the volatility in stockholders' equity from changes in currency exchange rates associated with our net investments in foreign operations. In July 2019, we terminated a portion of the foreign exchange hedging contract with a notional value of €70 million. The notional value of the remaining net investment hedges was €150 million at December 31, 2021. The arrangement is scheduled to settle in 2026.
In July 2019, we completed the registered public offering of €700 million aggregate principal amount of the 1.625% 2029 Senior Notes. We designated this euro-denominated debt as a non-derivative net investment hedge of a portion of our net investments in euro functional-currency denominated subsidiaries to offset foreign currency fluctuations.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Westlake Corporation is responsible for establishing and maintaining adequate internal control over financial reporting. Westlake's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
Westlake management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on its assessment, Westlake's management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2021 based on those criteria.
During the year ended December 31, 2021, the Company acquired the issued and outstanding equity interests of certain subsidiaries of Boral Industries engaged in Boral's North American building products businesses ("Boral Target Companies"). Because the Company acquired Boral Target Companies during the current fiscal year, management has excluded Boral Target Companies from the scope of its assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2021. This exclusion is in accordance with the general guidance published by the Staff of the SEC that an assessment of a recent business combination may be omitted from management's report on internal control over financial reporting in the first year of consolidation. Boral Target Companies' total assets and total net sales represented 4.7% and 2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.
PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has also audited the effectiveness of internal control over financial reporting as of December 31, 2021 as stated in their report that appears on the following page.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of Westlake Corporation
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Westlake Corporation (formerly known as Westlake Chemical Corporation) and its subsidiaries (the "Company") as of December 31, 2021 and 2020, and the related consolidated statements of operations, of comprehensive income, of changes in stockholders' equity and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
As described in Management's Report on Internal Control Over Financial Reporting, management has excluded certain subsidiaries acquired from Boral Industries engaged in Boral's North American building products businesses ("Boral Target Companies") from its assessment of internal control over financial reporting as of December 31, 2021 because they were acquired by the Company in a purchase business combination during 2021. We have also excluded the Boral Target Companies from our audit of internal control over financial reporting. The Boral Target Companies are wholly-owned subsidiaries whose total assets and total net sales excluded from management's assessment and our audit of internal control over financial reporting represent 4.7% and 2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.
Definition and Limitations of Internal Control over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Acquisition of Boral Target Companies - Valuation of Certain Customer Relationship Intangible Assets
As described in Notes 1 and 2 to the consolidated financial statements, on October 1, 2021, the Company completed its acquisition of the Boral Target Companies for a total purchase price of $2,132 million. The Company records business combinations using the acquisition method of accounting. Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values, which resulted in the recognition of $645 million of customer relationship intangible assets. As disclosed by management, the fair value of the customer relationships acquired is estimated with a discounted cash flow model using the multi-period excess earnings methodology, which involves the use of significant estimates and assumptions related to revenue growth rates, operating margins, discount rates, and customer attrition rates, among other items.
The principal considerations for our determination that performing procedures relating to the valuation of certain acquired customer relationship intangible assets from the acquisition of the Boral Target Companies is a critical audit matter are the significant judgment by management in determining the fair value of certain customer relationship intangible assets; this in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management's significant assumptions related to revenue growth rates, operating margins, discount rates, and customer attrition rates. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to acquisition accounting, including controls over management's valuation of certain customer relationship intangible assets and controls over the determination of significant assumptions related to revenue growth rates, operating margins, discount rates, and customer attrition rates. These procedures also included, among others, reading the purchase agreement and testing management's process for estimating the fair value of certain customer relationship intangible assets. Testing management's process included evaluating the appropriateness of the multi-period excess earnings method, testing the completeness and accuracy of the underlying data, and evaluating the reasonableness of management's significant assumptions related to revenue growth rates, operating margins, discount rates, and customer attrition rates. Evaluating the reasonableness of the revenue growth rates and operating margins involved considering the past performance of the acquired businesses, consistency with economic and industry forecasts, and whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the multi-period excess earnings method and in evaluating the reasonableness of the significant assumptions related to discount rates and customer attrition rates.

1. Description of Business and Significant Accounting Policies
Description of Business
Westlake Corporation, formerly known as Westlake Chemical Corporation (the "Company") operates as an integrated global manufacturer and marketer of performance and essential materials and housing and infrastructure products. These products include some of the most widely used materials in the world, which are fundamental to many diverse consumer and industrial markets, including residential construction, flexible and rigid packaging, automotive products, healthcare products, water treatment, coatings as well as other durable and non-durable goods. The Company's customers range from large chemical processors and plastics fabricators to small construction contractors, municipalities and supply warehouses throughout North America, Europe and Asia. The industries in which the Company operates are subject to price fluctuations and volatile feedstock pricing typical of a commodity-based industry, the effects of which may not be immediately passed along to customers. The Company changed its name from Westlake Chemical Corporation to Westlake Corporation on February 18, 2022.

In 2014, the Company formed Westlake Chemical Partners LP ("Westlake Partners") to operate, acquire and develop ethylene production facilities and related assets. Westlake Partners' assets consist of a limited partner interest in Westlake Chemical OpCo LP ("OpCo"), as well as the general partner interest in OpCo. OpCo's assets include two ethylene production facilities at the Company's Lake Charles, Louisiana site, one ethylene production facility at the Company's Calvert City, Kentucky site and a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu, Texas to the Company's Longview, Texas site. As of December 31, 2021, the Company held a 77.2% limited partner interest in OpCo and a controlling interest in Westlake Partners. The operations of Westlake Partners are consolidated in the Company's financial statements.
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and subsidiaries in which the Company directly or indirectly owns more than a 50% voting interest and exercises control and, when applicable, entities for which the Company has a controlling financial interest or is the primary beneficiary. Investments in majority-owned companies where the Company does not exercise control and investments in nonconsolidated affiliates (20%-50% owned companies, joint ventures and partnerships) are accounted for using the equity method of accounting. Undistributed earnings from joint ventures included in retained earnings were immaterial as of December 31, 2021. All intercompany transactions and balances are eliminated in consolidation.
Noncontrolling interests represent the direct equity interests held by investors in the Company's consolidated subsidiaries, Westlake Partners, Taiwan Chlorine Industries, Ltd. and Suzhou Huasu Plastics Co., Ltd.
The Company holds a 50% interest in RS Cogen, LLC ("RS Cogen") with Entergy Power RS, LLC ("Entergy") holding the remaining interest. Effective January 2021, the Company consolidated RS Cogen into its consolidated financial statements and classified Entergy's 50% interest in RS Cogen as a component of noncontrolling interest on the consolidated balance sheet.
Recasting of Certain Prior Period Information
The Company has historically operated in two principal operating segments, Vinyls and Olefins. In the fourth quarter of 2021, the Company reorganized its business into two principal operating segments, Performance and Essential Materials and Housing and Infrastructure Products. The Olefins, PVC, VCM, chlorine, caustic soda and chlorinated derivative materials and polyethylene are included in the Performance and Essential Materials segment. Building products, pipe and fittings and PVC compounds are included in the Housing and Infrastructure Products segment. These reporting changes have been retrospectively reflected in the segment results for all periods presented.
Certain reclassifications have been made to the prior-year financial statements to conform to the current year presentation.
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with the accounting principles generally accepted in the United States.

Cash and Cash Equivalents
Cash equivalents consist of highly liquid investments that are readily convertible into cash and have a maturity of three months or less at the date of acquisition.
Concentration of Credit Risk
Financial instruments which potentially subject the Company to concentration of risk consist principally of trade receivables from customers engaged in manufacturing polyethylene products, polyvinyl chloride ("PVC") products and PVC pipe products. The Company performs periodic credit evaluations of the customers' financial condition and generally does not require collateral. The Company maintains allowances for potential losses.
Allowance for Credit Losses
The determination of the allowance for credit losses is based on estimation of the amount of accounts receivable that the Company believes are unlikely to be collected. Estimating this amount requires analysis of the financial strength of the Company's customers, the use of historical experience, the Company's accounts receivable aged trial balance, customer specific collectability analysis and an evaluation of economic conditions. The allowance for credit losses is reviewed quarterly. Past due balances over 90 days and high-risk accounts as determined by the analysis of financial strength of customers are reviewed individually for collectability.
Inventories
Inventories primarily include product, material and supplies. Inventories are stated at lower of cost or net realizable value. Cost is determined using the first-in, first-out ("FIFO") or average method.
Property, Plant and Equipment
Property, plant and equipment are carried at cost, net of accumulated depreciation. Cost includes expenditures for improvements and betterments that extend the useful lives of the assets and interest capitalized on significant capital projects. Capitalized interest was $3, $4 and $9 for the years ended December 31, 2021, 2020 and 2019, respectively. Repair and maintenance costs are charged to operations as incurred. Gains and losses on the disposition or retirement of fixed assets are reflected in the consolidated statement of operations when the assets are sold or retired.
Depreciation is provided by utilizing the straight-line method over the estimated useful lives of the assets as follows:
Classification Years
Buildings and improvements 40
Plant and equipment 10-25
Other 3-15
Impairment of Long-Lived Assets
The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets assessed for impairment are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. Assets are considered to be impaired if the carrying amount of an asset exceeds the future undiscounted cash flows. The impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or estimated fair value less costs to sell.

(in millions of dollars, except share amounts and per share data)
Impairment of Goodwill and Intangible Assets
Goodwill is tested for impairment at least annually, or when events or changes in circumstances indicate the fair value of a reporting unit with goodwill has been reduced below its carrying value. The Company performed impairment tests for the Performance and Essential Materials and Housing and Infrastructure Products segments' goodwill in October 2021, and the impairment tests indicated that the recorded goodwill was not impaired. There has been no impairment of the goodwill since the goodwill was initially recorded. Other intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment in accordance with the provisions of the accounting guidance. See Note 8 for more information on the Company's annual goodwill impairment tests.
Equity Method Investments
The Company accounts for investments using the equity method of accounting if the Company has the ability to exercise significant influence over, but not control of, an investee. Significant influence generally exists if the Company has an ownership interest representing between 20% and 50% of the voting rights. Under the equity method of accounting, investments are stated initially at cost and are adjusted for subsequent additional investments and the proportionate share of profit or losses and distributions. The Company records its share of the profits or losses of the equity investments, net of income taxes, in the consolidated statements of income. The equity method investments are evaluated for impairment when events or changes in circumstances indicate, in management's judgment, that the carrying value of such investments may have experienced an other-than-temporary decline in value. When evidence of loss in value has occurred, management compares the estimated fair value of investment to the carrying value of investment to determine whether an impairment has occurred. If the estimated fair value is less than the carrying value and management considers the decline in value to be other-than-temporary, the excess of the carrying value over the estimated fair value is recognized in the consolidated financial statements as an impairment.
Other Assets, net
Other assets, net include turnaround costs, investments in unconsolidated subsidiaries, restricted cash, deferred charges and other long-term assets.
The Company accounts for turnaround costs under the deferral method. Turnarounds are the scheduled and required shutdowns of specific operating units in order to perform planned major maintenance activities. The costs related to the significant overhaul and refurbishment activities include maintenance materials, parts and direct labor costs. The costs of the turnaround are deferred when incurred at the time of the turnaround and amortized (within depreciation and amortization) on a straight-line basis until the next planned turnaround, which typically range from three to six years. Deferred turnaround costs are presented as a component of other assets, net. The cash outflows related to these costs are included in operating activities in the consolidated statement of cash flows.
Business Combinations
The Company records business combinations using the acquisition method of accounting. Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the purchase price over the estimated fair value is recorded as goodwill. Changes in the estimated fair values of net assets recorded for acquisitions prior to the finalization of more detailed analysis, but not to exceed one year from the date of acquisition, will adjust the amount of the purchase price allocable to goodwill. Measurement period adjustments are reflected in the period in which they occur.
Income Taxes
The Company utilizes the liability method of accounting for deferred income taxes. Under the liability method, deferred tax assets or liabilities are recorded based upon temporary differences between the tax basis of assets and liabilities and their carrying values for financial reporting purposes. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities during the period. Valuation allowances are recorded against deferred tax assets when it is considered more likely than not that the deferred tax assets will not be realized.

Foreign Currency Translation
Assets and liabilities of foreign subsidiaries are translated to U.S. dollars at the exchange rate as of the end of the year. Statement of operations items are translated at the average exchange rate for the year. The resulting translation adjustment is recorded as a separate component of stockholders' equity.
Revenue Recognition
Revenue is recognized when the Company transfers control of inventories to its customers. Amounts recognized as revenues reflect the consideration to which the Company expects to be entitled in exchange for those inventories. Provisions for discounts, rebates and returns are incorporated in the estimate of variable consideration and reflected as a reduction to revenue in the same period as the related sales.
Control of inventories generally transfers upon shipment for domestic sales. The Company excludes taxes collected on behalf of customers from the estimated contract price. For export contracts, the point at which control passes to the customer varies depending on the terms specified in the customer contract.
The Company generally invoices customers and recognizes revenue and accounts receivable upon transferring control of inventories. In limited circumstances, the Company transfers control of inventories shortly before it has an unconditional right to receive consideration, resulting in recognition of contract assets. The Company also receives advance payments from certain customers, resulting in recognition of contract liabilities. Contract assets and liabilities are generally settled within the period and are not material to the consolidated balance sheets. The Company expenses sales commissions when incurred. These costs are recorded within selling, general and administrative expenses. Aside from the amounts disclosed within Note 9, the Company does not disclose the value of unsatisfied performance obligations because its contracts with customers (1) have an original expected duration of one year or less or (2) have only variable consideration that is calculated based on market prices at specified dates and is allocated to wholly unsatisfied performance obligations.
ASU No. 2014-09, Revenue from Contracts with Customers ("ASC 606") requires disclosure of disaggregated revenue into categories that depict the nature of how the Company's revenue and cash flows are affected by economic factors. The Company discloses revenues by business and segment in Note 23.
Leases
The Company is obligated under various long-term and short-term operating leases for rail cars, buildings, land and other transportation and storage assets. The Company determines whether an arrangement is, or contains, a lease at contract inception. Some of the Company's arrangements contain both lease and non-lease components. For certain transportation equipment leases, the Company accounts for the lease and non-lease components as a single lease component. The Company records right-of-use assets and corresponding lease liabilities for operating leases with terms greater than one year. Operating lease right-of-use assets and liabilities are recorded at the present value of the fixed lease payments over the life of the lease. The majority of the Company's leases do not provide an implicit rate. Therefore, the Company uses its incremental borrowing rate at lease commencement to measure operating lease right-of-use assets and lease liabilities. Certain of the Company's leases provide for renewal and purchase options. Renewal and purchase options are evaluated at lease commencement and included in the lease term if they are reasonably certain to be exercised. Short-term leases are recognized in rental expense on a straight-line basis over the lease term and are not recorded in the consolidated balance sheets. The Company's finance leases are not material to the consolidated financial statements.

Transportation and Freight
Amounts billed to customers for freight and handling costs on outbound shipments are included in net sales in the consolidated statements of operations. Transportation and freight costs incurred by the Company on outbound shipments are included in cost of sales in the consolidated statements of operations.
Price Risk Management
The Company recognizes derivative instruments on the balance sheet at fair value, and changes in a derivative's fair value are currently recognized in earnings or comprehensive income, depending on the designation of the derivative. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded in comprehensive income and is recognized in the statement of operations when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings currently. The derivative instruments did not have a material impact on the Company's consolidated financial statements.
Asset Retirement Obligations
The Company has conditional asset retirement obligations for the removal and disposal of hazardous materials from certain of the Company's manufacturing facilities.
The Company recognizes asset retirement obligations in the period in which the liability becomes probable and reasonably estimable. Recognized asset retirement obligations are initially recorded at fair value and capitalized as a component of the carrying value of the long-lived asset to which the obligation relates. The liability is accreted to its future value each period, and the capitalized cost is depreciated over the estimated useful life of the related asset. Upon settlement of the liability, a gain or loss is recorded. As of December 31, 2021, the Company had $1 and $23 of asset retirement obligations recorded as accrued and other liabilities and other liabilities, respectively. As of December 31, 2020, the Company had $12 and $17 of asset retirement obligations recorded as accrued and other liabilities and other liabilities, respectively.
The Company also has conditional asset retirement obligations that have not been recognized because the fair values of the conditional legal obligations cannot be measured due to the indeterminate settlement date of the obligations. Settlements of the unrecognized conditional asset retirement obligations are not expected to have a material adverse effect on the Company's financial condition, results of operations or cash flows in any individual reporting period.
Environmental Costs
Environmental costs relating to current operations are expensed or capitalized, as appropriate, depending on whether such costs provide future economic benefits. Remediation liabilities are recognized when the costs are considered probable and can be reasonably estimated. Measurement of liabilities is based on currently enacted laws and regulations, existing technology and undiscounted site-specific costs. Environmental liabilities in connection with properties that are sold or closed are realized upon such sale or closure, to the extent they are probable and estimable and not previously reserved. Recognition of any joint and several liabilities is based upon the Company's best estimate of its final pro rata share of the liability.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
The coronavirus ("COVID-19") pandemic resulted in widespread adverse impacts on the global economy in 2020. As the COVID-19 pandemic and its impacts on the global economy continue, the Company may experience impacts on its business operations. However, the impact that COVID-19 will have on the financial condition, results of operations and cash flows of the Company cannot be estimated with certainty at this time as it will depend on future developments, including, among others, the timing and logistics with respect to the distribution of vaccines globally and the efficacy of the available vaccines (including with respect to the more recent variants of COVID-19), vaccine hesitancy and the availability of other treatments, the ultimate duration of the pandemic, geographic spread and severity of the virus, the consequences of governmental and other measures designed to prevent the spread of the virus, actions taken by customers, suppliers and other third parties, workforce availability, and the timing and extent to which normal economic and operating conditions resume.

Recent Accounting Pronouncements
Business Combinations - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers Update (ASU No.2021-08)
In October 2021, the Financial Accounting Standards Board ("FASB") issued an accounting standards update that requires acquiring entities to recognize and measure contract assets and contract liabilities in a business combination in accordance with the accounting guidance on Revenue from Contracts with Customers (ASC 606). The guidance in this update improves comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination. The accounting standard will be effective for reporting periods beginning after December 15, 2022. Early adoption of the guidance is permitted. The Company is in the process of evaluating the impact of this standard on the Company's consolidated financial position, results of operations and cash flows.
Recently Adopted Accounting Standards
Income Taxes (ASU No. 2019-12)
In December 2019, the FASB issued an accounting standards update removing certain exceptions for investments, intraperiod allocations and interim calculations and adding guidance to reduce complexity in accounting for income taxes. The accounting standard became effective for reporting periods beginning after December 15, 2020. The Company adopted this accounting standard effective January 1, 2021, and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Reference Rate Reform (ASU No. 2020-04)
In March 2020, the FASB issued an accounting standards update to provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions affected by reference rate reform, if certain criteria are met. The amendments in this update are effective for all entities from March 12, 2020 through December 31, 2022. The Company adopted this accounting standard effective October 1, 2021, and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
2. Acquisitions
Boral Target Companies in North America.
On June 20, 2021, the Company, through a wholly-owned subsidiary, entered into an Equity Purchase Agreement (the "Boral Purchase Agreement") by and among Boral Building Products Inc., a Michigan corporation, Boral Stone Products LLC, a Delaware limited liability company, Boral Lifetile Inc., a California corporation, Boral Windows LLC, a Utah limited liability company, Boral Industries Inc., a California corporation ("Boral Industries"), and solely for the limited purposes set forth therein, the Company, and Boral Limited, an Australian corporation ("Boral"). Pursuant to the terms of the Boral Purchase Agreement, the Company agreed to acquire from Boral Industries all of the issued and outstanding equity interests of certain subsidiaries of Boral Industries engaged in Boral's North American building products businesses in roofing, siding, trim and shutters, decorative stone and windows (the "Boral Target Companies") for a purchase price of $2,150 in cash, subject to working capital post-closing adjustments. The Boral Purchase Agreement also includes a potential earn-out payment from the Company to Boral Industries of up to $65 if the windows division of the Boral Target Companies generates EBITDA in excess of a specified target in its fiscal year ending June 30, 2024. On October 1, 2021, the Company completed its acquisition of, Boral Target Companies (the "Boral Acquisition") for a total purchase price of $2,132 in an all-cash transaction and accounted for the acquisition under the business combination method in accordance with Accounting Standard Codification Topic 805 ("ASC 805"), Business Combinations. The Boral Target Companies acquisition is consistent with the Company's vertical integration strategy of enhancing margin stability and downstream products. The additional product lines through the acquisition will broaden the Company's footprint in the fast-growing housing markets in North America. The assets acquired and liabilities assumed and the results of operations of Boral Target Companies are included in the Housing and Infrastructure Products segment.

A summary of the purchase consideration follows:
Base purchase price $ 2,150
Net working capital adjustment (2)
Closing indebtedness (16)
Total purchase price consideration $ 2,132
For the year ended December 31, 2021, the Company recognized acquisition-related costs of $17 for advisory, consulting and professional fees, and other expenses that were expensed as restructuring, transaction and integration-related costs as a component of the income from operations.
The following table summarizes the fair value of identified assets acquired and liabilities assumed at the date of acquisition. The preliminary allocation of consideration transferred is based on management's estimates, judgments and assumptions. These estimates, judgments and assumptions are subject to change upon final valuation and should be treated as preliminary values. Management estimated that consideration paid exceeded the fair value of the net assets acquired. Therefore, goodwill of $771 was recorded, most of which will not be deductible for income tax purposes. The goodwill is assigned to the Company's Housing and Infrastructure Products segment. The final allocation of purchase consideration could include changes in the estimated fair value of (1) inventories; (2) property, plant and equipment; (3) intangible assets comprising of customer relationships, trade names, developed technologies; (4) deferred income taxes; and (5) other assets.
The information below represents the purchase price allocation:
Cash $ 5
Accounts receivable 119
Inventories 156
Prepaid expenses and other current assets 3
Property, plant and equipment 489
Operating lease right-of-use assets 87
Intangible assets 952
Other assets 18
Total assets acquired 1,829
Accounts payable 46
Accrued and other liabilities 103
Deferred income taxes 244
Operating lease liabilities 73
Other liabilities 2
Total liabilities assumed 468
Total identifiable net assets acquired 1,361
Goodwill 771
Total purchase consideration $ 2,132
The excess of the total equity value of Boral based on the purchase consideration over net assets acquired was recorded as goodwill. The goodwill is primarily attributable to the synergies expected to arise after the acquisition. The synergies relate to enhanced leading positions in the home building products and materials sector and increased margin stability.

There are no indefinite-lived intangible assets derived acquired as a result of the Boral Target Companies acquisition. Definite lived intangible assets acquired as a result of the Boral acquisition are amortized on a straight-line basis to reflect the pattern in which the economic benefits of the intangible assets are realized.
The fair value for Trade name and Technology were estimated using the income approach, specifically the relief-from-royalty method which estimates the cost savings that accrue to the owner of the intangible assets that would otherwise be payable as royalties or licenses fees on revenues earned through the use of the asset. The fair value of Customer Relationships was estimated using the multi-period excess earnings method. The excess earning method model estimates revenues and cash flows derived from the asset and then deducts portions of the cash flow that can be attributed to supporting assets. The resulting cash flow, which is attributable solely to the asset acquired, is then discounted at a rate of return commensurate with the risk of the asset to calculate the present value.
Unaudited Pro Forma Financial Information
The acquired Boral Target Companies contributed net revenues and net loss of $275 and $15, respectively, to the Company for the period from October 1, 2021 to December 31, 2021.

2021 2020
Revenues
$ 12,653 $ 8,553
Net income attributable to Westlake Corporation
$ 2,035 $ 268
The amounts have been calculated after applying the Company's accounting policies and adjusting the results of Boral Target Companies to reflect additional depreciation, amortization, and other purchase accounting adjustment assuming the fair value adjustments to the property and equipment and intangibles assets and other purchase accounting adjustments have been applied on January 1, 2020. The pro forma amounts do not include any potential synergies, cost savings or other expected benefits of the acquisition, and are presented for illustrative purposes only and are not necessarily indicative of results that would have been achieved if the acquisition had occurred as of January 1, 2020 or of future operating performance.

8. Goodwill and Other Intangible Assets
Goodwill
The following table summarizes gross carrying amounts and changes in the carrying amount of goodwill for the years ended December 31, 2021 and 2020. The Company reorganized its operating segments during the fourth quarter of 2021. Prior year information has been updated to conform with the current year presentation for changes in operating segments discussed in Notes 1 and 23.
Performance and Essential Materials Segment Housing and Infrastructure Products Segment Total

Balance at December 31, 2021 $ 902 $ 1,122 $ 2,024
As part of the reorganization of operating segments, the Company assessed and re-defined reporting units effective as of the beginning of the fourth quarter of 2021, including reallocation of goodwill on a relative fair value basis as applicable to affected reporting units. Goodwill impairment analyses were performed as of the effective reorganization date both before and after the reorganization. The fair values of the reporting units were determined using both a discounted cash flow methodology and a market value methodology. Based upon this assessment, the Company determined that it was more likely than not that the fair value of the reporting units exceeds its carrying value both prior to the reorganization and after the reorganization.
The discounted cash flow projections were based on a long-term forecast to reflect the cyclicality of the Company's businesses. The forecast was based on prices and spreads projected by IHS Markit ("IHS"), a chemical industry organization offering market and business advisory services for the chemical market, historical results and estimates by management, including its strategic and operational plans. Other significant assumptions used in the discounted cash flow projection included projected sales volumes based on production capacities. The future cash flows were discounted to present value using a discount rate ranging from 8.8% to 10.8%. The significant assumptions used in determining the fair values of the reporting units using the market value methodology include the determination of appropriate market comparables and the estimated multiples of net income before interest expense, income taxes, depreciation and amortization ("EBITDA") a willing buyer is likely to pay.
Prior to the reorganization of the operating segments, the Company performed its annual impairment analysis for the legacy Vinyls segment reporting units during the second quarter of 2021, and determined that it was more likely than not that the fair value of each of the Vinyls segment reporting units exceeds its carrying value.

9. Equity Method Investments
LACC, LLC Joint Venture
In 2015, Eagle US 2 LLC ("Eagle"), a wholly-owned subsidiary of the Company, and Lotte Chemical USA Corporation, a subsidiary of Lotte Chemical Corporation ("Lotte"), formed a joint venture, LACC, LLC ("LACC"), to design, build and operate an ethylene facility with 2.2 billion pounds per year of ethylene production capacity. Pursuant to a contribution and subscription agreement between Eagle and LACC, Eagle contributed $225 to LACC to fund construction costs of the ethylene plant, representing approximately 12% of the membership interests in LACC.
On November 12, 2019, the Company, through Eagle, completed the acquisition of an additional 34.8% of the membership interests in LACC from Lotte for approximately $817. In January 2022, the Company notified Lotte of its exercise of an option to acquire an additional 3.2% of the membership interests in LACC from Lotte for approximately $90. As of December 31, 2021, the Company's investment exceeded the underlying equity in net assets by approximately $166 which was assigned to goodwill and not amortized.
The ethylene plant was built adjacent to the Company's chlor-alkali facility in Lake Charles. During the third quarter of 2019, the ethylene plant began commercial operations.
The Company accounts for its investment in LACC under the equity method of accounting. The LACC joint venture is a cost-sharing arrangement between the members of LACC. The members of LACC receive their proportionate shares of ethylene offtake each month and fund cash operating costs, excluding depreciation and amortization. As a result, LACC recognizes net losses equal to depreciation and amortization each period. The Company's equity in losses from LACC, which is equal to its share of depreciation and amortization expenses, is recognized in cost of sales in the consolidated statements of operations. The Company's investment in LACC is recorded as a component of equity method investments in the consolidated balance sheets. The Company's capital contributions to fund its share of capital expenditures are classified within investing activities in the consolidated statements of cash flows.
The Company's ethylene offtake from LACC was approximately 909 million and 787 million pounds during the years ended December 31, 2021 and 2020, respectively.
Changes in the Company's investment in LACC for the years ended December 31, 2021 and 2020 were as follows:
Investment in LACC
Balance at December 31, 2019 $ 1,038
Cash contributions 4

Services Provided to LACC and Lotte
The Company provides certain utilities and other services to LACC and Lotte. Pursuant to a construction and reimbursement agreement, LACC and Lotte agreed to reimburse the Company for construction costs over a 6.5-year period beginning in 2020. In addition to the reimbursements for construction costs, the Company charges LACC and Lotte certain fixed fees under an operating, maintenance and logistics agreement. The Company accounts for the reimbursement of construction costs and the fixed fees as components of the total transaction price and recognizes it ratably in net sales over approximately 25 years. The remaining performance obligations at December 31, 2021, representing these fixed components of the transaction price, totaled $55 and $76 from LACC and Lotte, respectively. The associated contract liabilities recorded from LACC and Lotte totaled $14 and $18 as of December 31, 2021, respectively, and $10 and $12 as of December 31, 2020, respectively. In addition to the reimbursements for construction costs and other fixed fees, the Company charges LACC and Lotte certain variable fees.
Other Equity Method Investments
In addition to LACC, the Company has other equity method investments amounting to $64 and $98 as of December 31, 2021 and 2020, respectively. See Note 20 for more detailed information.

If the Company is liquidated, dissolved or wound up, the holders of the Company's common stock will be entitled to a ratable share of any distribution to stockholders, after satisfaction of all the Company's liabilities and of the prior rights of any outstanding class of the Company's preferred stock. The Company's common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Company's common stock.
Preferred Stock
The Company's charter authorizes the issuance of shares of preferred stock. The Company's Board of Directors has the authority, without shareholder approval, to issue preferred shares from time to time in one or more series, and to fix the number of shares and terms of each such series. The Board may determine the designations and other terms of each series including dividend rates, whether dividends will be cumulative or non-cumulative, redemption rights, liquidation rights, sinking fund provisions, conversion or exchange rights and voting rights.
Stock Repurchase Program
In November 2014, the Company's Board of Directors approved a $250 share repurchase program (the "2014 Program"). In November 2015, the Company's Board of Directors approved the expansion of the 2014 Program by an additional $150. In August 2018, the Company's Board of Directors approved the expansion of the 2014 Program by an additional $150. The number of shares repurchased by the Company under the 2014 Program was 355,800, 995,529 and 517,712 for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, the Company had repurchased a total of 7,431,520 shares of its common stock for an aggregate purchase price of approximately $449.
Any shares repurchased under the 2014 Program are held by the Company as treasury stock and may be used for general corporate purposes, including for the 2013 Omnibus Incentive Plan. In 2014, the Company began delivering treasury shares to employees and non-employee directors for options exercised and for the settlement of restricted stock units. The cost of treasury shares delivered is determined using the specific identification method.

14. Employee Benefits
Defined Contribution Plans
U.S. Plans
The Company has a defined contribution savings plan covering the eligible U.S. regular full-time and part-time employees, whereby eligible employees may elect to contribute up to 100% of their annual eligible compensation, subject to an annual plan limit in line with the annual elective contribution limit as determined by the Internal Revenue Service. The Company matches its employee's contribution up to a certain percentage of such employee's compensation, per the terms of the plan. The Company may, at its discretion and per the terms of the plan, make an additional non-matching contribution in an amount as the Board of Directors may determine. For the years ended December 31, 2021, 2020 and 2019, the Company recorded approximately $24, $21 and $20, respectively, to expense for these contributions.
Further, within the plan, the Company also makes an annual retirement contribution to substantially all employees of certain subsidiaries. The Company's contributions to the plan are determined as a percentage of employees' pay. For the years ended December 31, 2021, 2020 and 2019, the Company charged approximately $35, $34 and $32, respectively, to expense for these contributions.
Non-U.S. Plans
The Company has defined contribution plans in several countries covering eligible employees of the Company. The Company's contributions to the plans are based on applicable laws in each country. Contributions to the Company's non-U.S. defined contribution plans are made by both the employee and the Company. For the years ended December 31, 2021, 2020 and 2019, the Company charged approximately $4, $4 and $4, respectively, to expense for its contributions to these plans.
Defined Benefit Plans
U.S. Plans
The Company has noncontributory defined benefit pension plans that cover certain eligible salaried and wage employees of certain subsidiaries. However, eligibility for the Company's plans has been frozen. Benefits for salaried employees under these plans are based primarily on years of service and employees' pay near retirement. Benefits for wage employees are based upon years of service and a fixed amount as periodically adjusted. The Company recognizes the years of service prior to the Company's acquisition of the subsidiary's facilities for purposes of determining vesting, eligibility and benefit levels for certain employees of the subsidiary and for determining vesting and eligibility for certain other employees of the subsidiary. The measurement date for these plans is December 31.
Non-U.S. Plans
The Company has defined benefit pension plans covering current and former employees associated with the Company's operations. These pension plans are closed to new participants. Benefits for employees for these plans are based primarily on employees' pay near retirement. The majority of these pension plans are unfunded and have no plan assets. The measurement date for the non-U.S. plans is December 31.

In the U.S., the Pension Protection Act of 2006 (the "Pension Protection Act") established a relationship between a qualified pension plan's funded status and the actual benefits that can be provided. Restrictions on plan benefits and additional funding and notice requirements are imposed when a plan's funded status is less than certain threshold levels. For the 2021 plan year, the funded status for the Company's U.S. pension plans are above 80% and, as such, are exempt from the Pension Protection Act's benefit restrictions.

Expected return on plan assets 7.0 % 4.0 % 7.0 % 4.0 % 7.0 % 4.0 %
Rate of compensation increase - % 2.6 % - % 2.6 % - % 2.6 %
The discount rates for the Company's U.S. and non-U.S. plans are determined using a benchmark pension discount curve and applying spot rates from the curve to each year of expected benefit payments to determine the appropriate discount rate for the Company. The assumed long-term return on plan assets is estimated by considering factors such as the plan's overall investment strategy, current economic conditions and historical averages.
The Company's U.S. pension plan investments are held in the Westlake Defined Benefit Plan. The Company's overall investment strategy for these pension plan assets is to achieve a balance between moderate income generation and capital appreciation. The investment strategy includes a mix of approximately 60% of investments for long-term growth, and 40% for near-term benefit payments with a diversification of asset types. These pension funds' investment policies target asset allocations from approximately 60% equity securities and 40% fixed income securities in order to pursue a balance between moderate income generation and capital appreciation.
Equity securities primarily include investments in large-cap and small-cap companies located in the U.S. and international developed and emerging markets stocks. Fixed income securities are comprised of investment and non-investment grade bonds, including U.S. Treasuries and U.S. and non-U.S. corporate bonds of companies from diversified industries. Each pension fund investment policy allows a discretionary range in various asset classes within the asset allocation model of up to 10%. The Company does not believe that there are significant concentrations of risk in the pension plan assets due to its strategy of asset diversification. At December 31, 2021, plan assets did not include direct ownership of the Company's common stock.
Under the accounting guidance for fair value measurements, inputs used to measure fair value are classified in one of three levels:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.

15. Stock-Based Compensation
Under the Westlake Chemical Corporation 2013 Omnibus Incentive Plan (as amended and restated in 2017, the "2013 Plan"), all employees and non-employee directors of the Company, as well as certain individuals who have agreed to become the Company's employees, are eligible for awards. Shares of common stock may be issued as authorized in the 2013 Plan. At the discretion of the administrator of the 2013 Plan, employees and non-employee directors may be granted awards in the form of stock options, stock appreciation rights, stock awards, restricted stock units or cash awards (any of which may be a performance award). Outstanding stock option awards have a 10-year term and vest (1) ratably on an annual basis over a three-year period or (2) at the end of a five-year period. Outstanding restricted stock units and performance stock units vest either (1) ratably on an annual basis over a two to five-year period or (2) at the end of a three or six-year period. In accordance with accounting guidance related to share-based payments, stock-based compensation expense for all stock-based compensation awards is based on estimated grant-date fair value. The Company recognizes these stock-based compensation costs net of a forfeiture rate and on a straight-line basis over the requisite service period of the award for only those shares expected to vest. For the years ended December 31, 2021, 2020 and 2019, the total recognized stock-based compensation expense related to equity awards issued under the 2013 Plan was $31, $29 and $24, respectively.

This amount changes based on the fair market value of the Company's common stock. For the years ended December 31, 2021, 2020 and 2019, the total intrinsic value of options exercised was $9, $11 and $1, respectively.
As of December 31, 2021, $7 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.7 years. Income tax benefits of $2, $2 and $0 were realized from the exercise of stock options during the years ended December 31, 2021, 2020 and 2019, respectively.

The total fair value of restricted stock units that vested during the years ended December 31, 2021, 2020 and 2019 was $18, $12 and $28, respectively.
Performance stock unit payout is based on the greater of the average annual economic-value added results for the Company (equal to net operating profit after tax less a capital charge based upon the weighted average cost of capital) and relative total shareholder return as compared to a peer group of companies. The units have payouts that range from zero to 200 percent of the target award.
Non-vested performance stock units as of December 31, 2021 and changes during the year ended December 31, 2021 were as follows:

Westlake Chemical Partners LP Awards
The Company's wholly-owned subsidiary and the general partner of Westlake Partners, Westlake Chemical Partners GP LLC ("Westlake Partners GP"), maintains a unit-based compensation plan for directors and employees of WLKP GP and Westlake Partners.
The Westlake Partners 2014 Long-term Incentive Plan ("Westlake Partners 2014 Plan") permits various types of equity awards including but not limited to grants of phantom units and restricted units. Awards granted under the Westlake Partners 2014 Plan may be settled with Westlake Partners units or in cash or a combination thereof. Compensation expense for these awards was not material to the Company's consolidated financial statements for the years ended December 31, 2021, 2020 and 2019.
16. Fair Value Measurements
The Company has financial assets and liabilities subject to fair value measures. These financial assets and liabilities include cash and cash equivalents, accounts receivable, net, accounts payable and long-term debt, all of which are recorded at carrying value. The amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, net and accounts payable approximate their fair value due to the short maturities of these instruments. The carrying and fair values of the Company's long-term debt at December 31, 2021 and 2020 are summarized in the table below. The Company's long-term debt instruments are publicly-traded. A market approach, based upon quotes from financial reporting services, is used to measure the fair value of the Company's long-term debt. Because the Company's long-term debt instruments may not be actively traded, the inputs used to measure the fair value of the Company's long-term debt are classified as Level 2 inputs within the fair value hierarchy.

At December 31, 2021, the Company had federal, foreign and state net operating loss carryforwards ("NOLs") of approximately $22, $188 and $722, respectively. The federal NOL was acquired in connection with the acquisition of Dimex. The federal NOL and certain foreign and state NOLs do not expire, while certain other foreign and state NOLs expire in varying amounts between 2022 and 2041. The federal NOL and certain state NOLs are subject to limitations on an annual basis. At December 31, 2021, the Company had various federal, foreign and state credits carryforwards of $2, $2 and $19, respectively, which either do not expire or expire in varying amounts between 2022 and 2036. Management believes the Company will realize the benefit of a portion of the net operating loss carryforwards before they expire, but to the extent that the full benefit may not be realized, a valuation allowance has been recorded. The valuation allowance decreased by $29 in 2021, primarily due to the release in valuation allowance resulting from a change in management judgment regarding the realizability of certain foreign deferred tax assets, including net operating loss carryforward, as a result of the change in expectations of income in future years.
The Company has recognized a liability for uncertain income tax positions of $18 as of December 31, 2021. The Company does not believe it is likely that any material amounts will be paid in 2022. The ultimate resolution and timing of payment for remaining matters continues to be uncertain.
The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company is no longer subject to examinations by tax authorities before the year 2014.
18. Earnings and Dividends per Share
The Company has unvested restricted stock units outstanding that are considered participating securities and, therefore, computes basic and diluted earnings per share under the two-class method. Basic earnings per share for the periods are based upon the weighted average number of shares of common stock outstanding during the periods. Diluted earnings per share include the effects of certain stock options and performance stock units.

22. Commitments and Contingencies
The Company is involved in a number of legal and regulatory matters, principally environmental in nature, that are incidental to the normal conduct of its business, including lawsuits, investigations and claims. The outcome of these matters are inherently unpredictable. The Company believes that, in the aggregate, the outcome of all known legal and regulatory matters will not have a material adverse effect on its consolidated financial statements; however, under certain circumstances, if required to recognize costs in a specific period, when combined with other factors, outcomes with respect to such matters may be material to the Company's consolidated statements of operations in such period. The Company's assessment of the potential impact of environmental matters, in particular, is subject to uncertainty due to the complex, ongoing and evolving process of investigation and remediation of such environmental matters, and the potential for technological and regulatory developments. In addition, the impact of evolving claims and programs, such as natural resource damage claims, industrial site reuse initiatives and state remediation programs creates further uncertainty of the ultimate resolution of these matters. The Company anticipates that the resolution of many legal and regulatory matters, and in particular environmental matters, will occur over an extended period of time.

Antitrust Proceedings. The Company and other caustic soda producers were named as defendants in multiple purported class action civil lawsuits filed since March 2019 in the U.S. District Court for the Western District of New York. The lawsuits allege the defendants conspired to fix, raise, maintain and stabilize the price of caustic soda, restrict domestic (U.S.) supply of caustic soda and allocate caustic soda customers. The other defendants named in the lawsuits are Olin Corporation, K.A. Steel Chemicals (a wholly-owned subsidiary of Olin), Occidental Petroleum Corporation, Occidental Chemical Corporation d/b/a OxyChem, Shin-Etsu Chemical Co., Ltd., Shintech Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A. Each of the lawsuits is filed on behalf of the respective named plaintiff or plaintiffs and a putative class comprised of either direct purchasers or indirect purchasers of caustic soda in the U.S. The plaintiffs seek an unspecified amount of damages and injunctive relief. Three of the defendants, Occidental Petroleum Corporation, Shin-Etsu Chemical Co., Ltd. and Formosa Plastics Corporation, were dismissed on jurisdictional or other grounds. The other six defendants, including the Company, remain in the case. The defendants' joint motion to dismiss the direct purchaser lawsuits was denied and the cases have proceeded to discovery. Beginning in October 2020, similar class action proceedings were also filed in Canada before the Superior Court of Quebec as well as before the Federal Court. These proceedings seek the certification or authorization of a class action on behalf of all residents of Canada who purchased caustic soda (including, in one of the cases, those who merely purchased products containing caustic soda) from October 1, 2015 through the present or such date deemed appropriate by the court. On December 10, 2021, the Superior Court of Québec stayed its proceedings, until after a final certification decision is released in the Federal Court proceedings. At this time, the Company is not able to estimate the impact, if any, that these lawsuits could have on the Company's consolidated financial statements either in the current period or in future periods.
Environmental. As of December 31, 2021 and 2020, the Company had reserves for environmental contingencies totaling approximately $56 and $53, respectively, most of which was classified as noncurrent liabilities. The Company's assessment of the potential impact of these environmental contingencies is subject to considerable uncertainty due to the complex, ongoing and evolving process of investigation and remediation, if necessary, of such environmental contingencies, and the potential for technological and regulatory developments.
Calvert City Proceedings. For several years, the Environmental Protection Agency (the "EPA") has been conducting remedial investigation and feasibility studies at the Company's Calvert City, Kentucky facility pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA"). As the current owner of the Calvert City facility, the Company was named by the EPA as a potentially responsible party ("PRP") along with Goodrich Corporation ("Goodrich") and its successor-in-interest, Avient Corporation (formerly known as PolyOne Corporation, "Avient"). On November 30, 2017, the EPA published a draft Proposed Plan, incorporating by reference an August 2015 draft Remedial Investigation ("RI") report, an October 2017 draft Feasibility Study ("FS") report and a Technical Impracticability Waiver document dated December 19, 2017. On June 18, 2018, the EPA published an amendment to its Proposed Plan. The amended Proposed Plan describes a final remedy for the onshore portion of the site comprised of a containment wall, targeted treatment and supplemental hydraulic containment. The amended Proposed Plan also describes an interim approach to address the contamination under the river that would include recovery of any mobile contaminants by an extraction well along with further study of the extent of the contamination and potential treatment options. The EPA's estimated cost of implementation is $107, with an estimated $1 to $3 in annual operation and maintenance ("O&M") costs. In September 2018, the EPA published the Record of Decision ("ROD") for the site, formally selecting the preferred final and interim remedies outlined in the amended Proposed Plan. In October 2018, the EPA issued Special Notice letters to the PRPs for the remedial design phase of work under the ROD. In April 2019, the PRPs and the EPA entered into an administrative settlement agreement and order on consent for remedial design. In October 2019, the PRPs received special notice letters for the remedial action phase of work at the site. The Company, jointly with the other PRPs, submitted a good faith offer response in December 2019. On September 17, 2020, the EPA and the Department of Justice filed a proposed consent decree for the remedial action with the U.S. District Court for the Western District of Kentucky. On November 16, 2020, the Department of Justice filed a motion to approve and enter the consent decree. On January 28, 2021, the Court granted the unopposed motion to enter the consent decree, which became effective the same day. The Company's allocation of liability for remedial and O&M costs at the Calvert City site, if any, is governed by a series of agreements between the Company, Goodrich and Avient. These agreements and the associated litigation are described below.

In connection with the 1990 and 1997 acquisitions of the Goodrich chemical manufacturing complex in Calvert City, Goodrich agreed to indemnify the Company for any liabilities related to preexisting contamination at the complex. For its part, the Company agreed to indemnify Goodrich for post-closing contamination caused by the Company's operations. The soil and groundwater at the complex, which does not include the Company's nearby PVC facility, had been extensively contaminated by Goodrich's operations. In 1993, Goodrich spun off the predecessor of Avient, and that predecessor assumed Goodrich's indemnification obligations relating to preexisting contamination. In 2003, litigation arose among the Company, Goodrich and Avient with respect to the allocation of the cost of remediating contamination at the site. The parties settled this litigation in December 2007 and the case was dismissed. In the settlement, the parties agreed that, among other things: (1) Avient would pay 100% of the costs (with specified exceptions), net of recoveries or credits from third parties, incurred with respect to environmental issues at the Calvert City site from August 1, 2007 forward; and (2) either the Company or Avient might, from time to time in the future (but not more than once every five years), institute an arbitration proceeding to adjust that percentage. In May 2017, Avient filed a demand for arbitration. In this proceeding, Avient sought to readjust the percentage allocation of future costs and to recover approximately $11 from the Company in reimbursement of previously paid remediation costs. The Company's cross demand for arbitration seeking unreimbursed remediation costs incurred during the relevant period was dismissed from the proceedings when Avient paid such costs in full at the beginning of the arbitration hearing.
On July 10, 2018, Avient sued the Company in the U.S. District Court for the Western District of Kentucky and sought to invalidate the arbitration provisions in the parties' 2007 settlement agreement and enjoin the arbitration it had initiated in 2017. On July 30, 2018, the district court refused to enjoin the arbitration and, on January 15, 2019, the court granted the Company's motion to dismiss Avient's suit. On February 13, 2019, Avient appealed those decisions to the U.S. Court of Appeals for the Sixth Circuit. The court of appeals issued an opinion and final order on September 6, 2019, affirming the district court.
The arbitration hearing began in August 2018 and concluded in December 2018. On May 22, 2019, the arbitration panel issued its final award. It determined that Avient was responsible for 100% of the allocable costs at issue in the proceeding and that Avient would remain responsible for 100% of the costs to operate the existing groundwater remedy at the Calvert City site. In August 2019, Avient filed a motion to vacate before the U.S. District Court for the Western District of Kentucky, seeking to invalidate the final award under the Federal Arbitration Act. On February 11, 2020, the U.S. District Court for the Western District of Kentucky denied Avient's motion to vacate and affirmed the arbitration final award. Avient did not file a notice of appeal before the March 10, 2020 deadline to contest the court's decision. Accordingly, the final award was affirmed, and the arbitration proceeding is fully and finally resolved.
At this time, the Company is not able to estimate the impact, if any, that any subsequent arbitration or judicial proceeding could have on the Company's consolidated financial statements either in the current period or in later periods. Any cash expenditures that the Company might incur in the future with respect to the remediation of contamination at the Calvert City complex would likely be spread out over an extended period. As a result, the Company believes it is unlikely that any remediation costs allocable to it will be material in terms of expenditures made in any individual reporting period.
Environmental Remediation: Reasonably Possible Matters. The Company's assessment of the potential impact of environmental contingencies is subject to considerable uncertainty due to the complex, ongoing and evolving process of investigation and remediation, if necessary, of such environmental contingencies, and the potential for technological and regulatory developments. As such, in addition to the amounts currently reserved, the Company may be subject to reasonably possible loss contingencies related to environmental matters in the range of $65 to $130.
Other Commitments
The Company has various unconditional purchase obligations, primarily to purchase goods and services, including commitments to purchase various utilities, feedstock, nitrogen, oxygen, product storage and pipeline usage. At December 31, 2021, unrecorded unconditional total purchase obligations were $5,079, which included approximately $922 in 2022, $695 in 2023, $590 in 2024, $571 in 2025, $511 in 2026, and $1,790 thereafter.

23. Segment and Geographic Information
Segment Information
The Company has historically operated in two principal operating segments, Vinyls and Olefins. In conjunction with the 2021 Acquisitions discussed in Note 2, and a resulting significant increase in the size of the Company's housing and infrastructure products operations, the Company reorganized its business into two principal operating segments, Performance and Essential Materials and Housing and Infrastructure Products, during the fourth quarter of 2021. These segments are strategic business units that offer a variety of different materials and products. The Company manages each segment separately as each business requires different technology and marketing strategies. These reporting changes have been retrospectively reflected in the segment results for all periods presented.
The Company's Performance and Essential Materials segment manufactures and markets polyethylene, styrene monomer, ethylene co-products, PVC, VCM, ethylene dichloride ("EDC"), chlor-alkali (chlorine and caustic soda), and chlorinated derivative products. The Company's ethylene production is used in the Company's polyethylene, styrene and VCM operations. In addition, the Company sells ethylene and ethylene co-products, primarily propylene, crude butadiene, pyrolysis gasoline and hydrogen, to external customers. The Company's primary North American manufacturing facilities are located in its Calvert City, Kentucky; Lake Charles, Plaquemine and Geismar, Louisiana and Longview, Texas sites. The Company produces ethylene and polyethylene at its facilities in Lake Charles, Louisiana; Calvert City, Kentucky and Longview, Texas. The Company produces chlorine, caustic soda, VCM, EDC, PVC, hydrogen and chlorinated derivative materials at its facilities in Lake Charles, Plaquemine and Geismar, Louisiana; Calvert City, Kentucky; Natrium, West Virginia; Longview, Washington; Beauharnois, Quebec and Aberdeen, Mississippi. In addition to North America, the Company also has manufacturing facilities in Europe and Asia.
No single customer accounted for more than 10% of sales in the Performance and Essential Materials segment for the years ended December 31, 2021, 2020 or 2019.
The Housing and Infrastructure Products segment manufactures and markets products including residential siding, trim and mouldings, stone, roofing, windows, outdoor living products, PVC pipe and fittings and PVC compounds. As of December 31, 2021, the Company owned or leased 75 manufacturing facilities in North America, Europe and Asia. The Company's North American PVC facilities within the Performance and Essential Materials segment supply most of the PVC required for the building products and pipes and fittings plants. The raw materials for stone, roofing and accessories, windows, shutters and specialty tool products are externally purchased. PVC required for the PVC compounds plants is either internally sourced from Company's North American or Asian facilities or externally purchased at market prices based on the location of the plants.
No single customer accounted for more than 10% of sales in the Housing and Infrastructure Products segment for the years ended December 31, 2021, 2020 or 2019.
The accounting policies of the individual segments are the same as those described in Note 1.

ITEM 9A. CONTROLS AND PROCEDURES
Item 9A. Controls and Procedures
Disclosure, Controls and Procedures
We carried out an evaluation, under the supervision and with the participation of our management, including our President and Chief Executive Officer (our principal executive officer) and our Executive Vice President and Chief Financial Officer (our principal financial officer), of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934 as of the end of the period covered by this Form 10-K. Based upon that evaluation, our President and Chief Executive Officer and our Executive Vice President and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of December 31, 2021 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure.
Internal Control Over Financial Reporting
Westlake's management's report on internal control over financial reporting appears on page 53 of this Annual Report on Form 10-K. In addition, PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has also audited the effectiveness of internal control over financial reporting as of December 31, 2021, as stated in their report that appears on page 54 of this Annual Report on Form 10-K.
Changes in Internal Control Over Financial Reporting
Except as described below, there were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
During the year ended December 31, 2021, we acquired the issued and outstanding equity interests of certain subsidiaries of Boral Industries engaged in Boral's North American building products businesses ("Boral Target Companies"). We are in the process of integrating Boral North America into our overall internal control over financial reporting process. Because we acquired Boral Target Companies during the current fiscal year, we excluded Boral Target Companies from the scope of our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2021. This exclusion is in accordance with the general guidance published by the Staff of the SEC that an assessment of a recent business combination may be omitted from management's report on internal control over financial reporting in the first year of consolidation. Boral Target Companies' total assets and total net sales represented 4.7% and 2.3% respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.
