Industry and market data used throughout table 10 K is obtained through internal corporate research, surveys and research conducted by unrelated third parties and publicly available industry and general publications, including information from IHS Markit (\"IHS\"). We do not independently verify market and industry data from external sources. While we believe that internal company estimates are reliable and market definitions are appropriate, none of these estimates and definitions are validated by any independent source. Unless otherwise stated by us, the annual production capacity estimates used in Table 10- K represents the rated capacity of the facility in December 31, 2018. We calculate the rated capacity by estimating the number of days in typical years where the plant production unit is expected to operate, after allowing downtime for regular maintenance, and multiply that number by the amount equal to the best daily output per unit based on the design of the raw material mixture. Because the rated capacity of a production unit is an estimated amount, the actual production capacity may be more or less than the rated capacity. Part 2 Catalogue Part 1 item 1. We are a global manufacturer and marketer of vertically integrated base chemicals, vinyls, polymers and building products. Our products include some of the most widely used chemicals in the world that are critical to many different consumer and industrial markets, including flexible and rigid packaging, automotive products, coatings, water treatment, refrigerant, residential and commercial buildings and other durable and non-durable goods.

Ethylene. In terms of volume, ethylene is the most widely used petrochemical product in the world. It is the key building block used to generate a lot of higher value -- Chemicals including polyethylene, EDC, VCM and styrene were added. The production capacity of OpCo is about 3. Our olefin plant at Lake Charles plant has a billion lbs of ethylene per year, and we have the ability to consume all the OpCo products we buy at Lake Charles to produce polyethylene and styrene monomer in the olefin business, and produce VCM and EDC in Vinyls business. OpCo also produces ethylene for our Vinyls department at Calvert City website, and most of the ethylene we buy from OpCo in Calvert City is used internally for VCM production. For the OpCo annual ethylene production we purchased for our Vinyls business, see \"business-Vinyls business. \"Plus, we (through OpCo) Production of ethylene The products include chemical grade propylene, crude benzene, cracked gasoline and hydrogen. We (through OpCo) Sell all our products Provide products to external customers. In 2016, OpCo completed the upgrade and capacity expansion of its Petro 1 ethylene unit at our Lake Charles plant, which increases OpCo ethylene capacity by approximately £ 0. 25 billion per year. Polyethylene. Polyethylene is the most widely consumed polymer in the world and is used to manufacture various film, coating and molded product applications mainly used for packaging. Polyethylene is often classified as low-density polyethylene, llannan, or high Density Polyethylene (\"HDPE\"). Density is related to the relative stiffness of the enduse products. The difference between low-density polyethylene and LLDPE is molecular, and products usually produced by LLDPE have higher strength properties than those produced by low-density polyethylene. Low Density Polyethylene has better definition and other physical properties for final products such as bread bags, dry cleaners, food packaging, milk box coating and food packaging. Llannan is used for applications with higher film strength such as stretch film and heavy duty bag. High Density Polyethylene is used to manufacture products such as groceries, goods and garbage bags, hard plastic containers, plastic caps and pipes. We are a leading manufacturer of low density polyethylene in North America, mainly using autoclave technology ( Compared with tubular technology) Can produce high profit special polyethylene products. In 2018, our annual capacity was about 1. To meet the needs of our diverse customer base, there is a £ 5 billion formula to choose from. We also have the ability to produce about one. The various formulations of llannan are 1 billion pounds per year. We produce low density polyethylene and llannan at Lake Charles and Longview facilities. Our Charles Lake and Longview facilities are also capable of producing high density polyethylene. We sell polyethylene as final product to external customers in pellet form. Styrene. Derivatives such as polystyrene, acrylic-benzene, unsaturated polyester and synthetic rubber are produced from benzene. These derivatives are used in many applications including consumer goods, food packaging, household goods, paints and coatings, building materials, tires and toys. We produce styrene at Lake Charles plant, where we have the ability to produce approximately £ 0. 57 billion of it per year, all of which are sold to external customers. We are highly integrated in the olefin product chain. We (through OpCo) Produce most of the ethylene we need to produce polyethylene and styrene. Ethylene can be produced from petroleum liquid raw materials such as naphtha, condensate and gas oil, or from natural gas liquid raw materials such as ethane, propane, and ethanol. The Charles Lake ethylene plant in OpCo is mainly made of ethane. According to the raw material supply agreement between us and OpCo, OpCo receives ethylene raw materials through several pipelines from various suppliers in Texas and Luis Anna state at our olefin facility on site in Lake Charles. We have 50% of 104 rights and interests Miles of gas and liquid pipeline from Mount Bellevue to Lake Charles. OpCo has 200- From Mount Bellevue to the mile ethylene pipeline of our Longview website. In addition to the ethylene supplied by OpCo, we also purchase ethylene from third parties to meet some of our ethylene needs. We use the production of polyethylene and benzene as raw materials, and purchase Zhengding benzene and hexene to produce styrene. We received dingone and hexene at Lake Charles site through several supplier railcars, and received hexene at Longview site. We receive benzene through barges, boats and pipes. Semester arrangements. We buy more than butenes and hexene.

The environment is common in our industry and we are subject to environmental laws and regulations related to use, storage, processing, power generation, transportation, emissions, disposal and remediation, exposure to hazardous and non-hazardous environments There are hazardous substances and waste in all countries where we do business. National, state or provincial and local standards for managing air, water and land quality have basically affected all our manufacturing locations around the world. Compliance with these laws and regulations has and will continue to require capital expenditures and increased operating costs. Our policy is to comply with all environmental, health and safety requirements to provide a safe and eco-friendly workplace for our employees. In some cases compliance can only be achieved by generating capital expenditures. In 2018, our capital expenditure on environmental compliance was $23 million. We estimate that capital expenditures related to environmental compliance in 2019 and 2020 were approximately $47 million and $45 million, respectively. Estimated capital expenditure of 2019 and 2020 is relatively higher than our expenditure related to environmental compliance in recent years, which is largely due to capital expenditure related to EPA (the \"EPA\")regulations. The rest of the estimated expenditures for 2019 and 2020 are related to equipment replacement and upgrading. We expect to continue to impose strict environmental regulations on us and the industry as a whole. Although we cannot predict future expenditures with certainty, management is confident that our current spending trend will continue. From time to time, we receive notification or inquiries from government entities regarding alleged violations of environmental laws and regulations related to the disposal, discharge and storage of chemical substances, including hazardous waste S-regulated by SEC 103 When the government authorities are the party to the proceedings, which involve potential monetary sanctions, K requires disclosure of certain environmental matters, unless we reasonably believe that such sanctions will not exceed $100,000. 6 The catalogue of May 2013, the amendment to the existing consent order agreed by the Ministry of Environmental Protection of West Virginia, and the predecessor of Axiall, inter alia, requiring it to pay a fine of $449,000, and continue to take certain corrective measures in connection with hcexane emissions ( Usually called BHC) From the sewage discharged from the sodium plant The penalty has been paid and corrective action is required- Pursuant to the agreement of December 2018, the compliance date is extended in accordance with the amended consent order. The revised consent order also provides penalties that exceed the facility\'s temporary wastewater discharge limit, and we believe that the total amount of these penalties may reach or exceed $100,000. During September2010, we received a comprehensive compliance order and a notice of potential penalties at the vinyls facility in Lake Charles and prakming, alleging violations of the air at these facilities Reporting license deviations related to records Keep violations. We have been negotiating global solutions to these and several other issues with the environmental quality department of Luiz Anna (\"LDEQ\"). On May 2018, we reached a major agreement with LDEQ to resolve these consolidated enforcement matters with a fine of $162,500. The settlement agreement is under preparation and will be publicly reviewed and approved by the attorney general of the state of Luis Anna upon final determination. Over the years, the Environmental Protection Agency has been implementing law enforcement measures against refineries and petrochemical plants on the release of the bomb. On April 21, 2014, we received EPA\'s request for information in Section 114 of the Clean Air Act, which requires the provision of flare information for Calvert City facilities and certain facilities in Lake Charles. We have been informed by EPA that the information provided led to the EPA\'s belief that some of the flares did not meet the applicable standards. The Environmental Protection Agency says it is seeking a consent decree that requires us to take corrective measures against alleged non-compliance. We believe that addressing these issues may require payment of monetary sanctions over $100,000. EPA\'s regional offices have investigated and, in some cases, checked our compliance with the risk management plan requirements under the Clean Air Act at sodium and Geismar facilities. We believe that addressing these issues may require payment of monetary sanctions over $100,000. On November 24, 2014, we reached an agreement order with the Kentucky Energy and Environment Cabinet (\"KEEC\") Regarding the limits that our Kentucky pollutant discharge removal system at our factory in Calvert City allows for the release of HCB and Mercury. On July 9, 2018, we reached a new agreed order with KEEC under which, in addition to the penalties imposed on excess of these temporary emission limits, we will also be subject to the new HCB interim in general, what penalties do we think may reach or exceed $100,000. We believe that addressing any or all of these issues will not have a significant adverse effect on our financial position, results of operations or cash flows. Please also see our discussion of environmental matters contained in Item 1a \"risk factors\", item 3, \"legal procedures\" below and note 19 to the consolidated financial statements contained in Item 8 of this formK. As of December 31, 2018, we have approximately 8,870 employees in the following areas: category no olefin part 850 Vinyls part 7,680 company and other 340 approximately 33% employees represented by the Union, all of these union employees work under the collective bargaining agreement, which expires at different times before 2022. We have a number of collective bargaining agreements in Europe, Canada and the United States that cover different groups of our workforce. There were no strikes, stoppages or stoppages in 2018 and we thought our relationship with our employees and unions was open and positive. Historically, our technical strategy is to selectively obtain licenses from third parties. And develop our own proprietary technology. Our selection process includes a number of factors, including technical costs, the ability to meet customer requirements, raw materials and energy consumption rates, product quality, capital costs, maintenance requirements and reliability. Most of the technology licensed from third parties The party provider is permanent and has paid in full. We have a portfolio of intellectual property developed from the focus of process and product technology. After acquiring or developing a technology, we have put a lot of effort into effectively utilizing it and further developing it, with a focus on continuously improving our competitive position. Instead, we selectively license our patented energy®The technology used in the production of LLDPE and the technology used in the mixing technology of proprietary low density polyethylene reactor. We have also granted several licenses for EDC/VCM technology, including direct chloride processes and catalysts, as well as S-PVC ( Suspended PVC for hot plastic process) Process and Technology.

Com under \"Investor Relations/corporate governance. \" Item 1A. The risk factors in the petrochemical industry are cyclical and may lead to lower operating profit margins or operational losses in the past and in the future. Our historical results reflect the cyclical and volatile nature of the petrochemical industry. Mature industry, capital intensive. Profit margins in this industry are sensitive to both domestic and international balance of supply and demand, which is historically cyclical. These cycles are often characterized by tight supply, resulting in high operating rates and profit margins, followed by oversupply mainly due to new overcapacity, resulting in lower operating rates and lower profit margins. In addition, the profitability of the petrochemical industry is affected by the level of global demand, while price competition may increase due to new industry capacity. Overall, weak economic conditions in the US, Europe or the rest of the world tend to reduce demand and put pressure on profit margins. It is impossible to accurately predict the factors that will affect the supply and demand balance and market conditions of the industry\'s operating profit margin in the future. New olefin capacity increases in Asia, the Middle East and North America, some of which have recently been completed, may result in excess capacity Supply and lower profitability. Therefore, the operating profit of our olefin sector may be negatively affected. We sell goods in a highly competitive market, facing great competition and price pressure. We sell our products in a competitive market. Due to the commodity nature of many of our products, the competition in these markets is mainly based on price and, to a lesser extent, on performance, product quality, product delivery capability and customer service. As a result, we often cannot protect the market position of these products through product differences, or we may not be able to pass on the cost increase to our customers. Therefore, the increase in raw materials and other costs may not necessarily be related to the price changes of these products, whether in the direction or magnitude of the price changes. Specifically, the pricing time difference between the price of raw materials (which may vary daily) and the price of the contract product (in many cases, the price of the contract product is negotiated monthly or less), sometimes, due to the additional lag on the effective date of the increase, it has and may continue to have a negative impact on profitability. Large fluctuations in raw material costs often put pressure on product profit margins, as rising sales prices may lag behind rising raw material costs. Instead, when the cost of raw materials drops, customers can seek relief at a lower selling price. 8 fluctuations in raw material and energy costs may result in an increase in operating costs and adversely affect our operating results and cash flows. Significant changes in the cost and availability of raw materials and energy may have a negative impact on our operational results. In the past, these costs have risen sharply, mainly due to increased costs for oil and gas. In order to produce several basic chemicals, we have purchased a large amount of ethane raw materials, natural gas, ethylene and salt. We also buy a lot of electricity to supply the energy we need in our production process. In general, the cost of these raw materials and energy accounts for a large part of our operating expenses. The prices of raw materials and energy generally follow the price trend of crude oil and natural gas and change with changes in market conditions, which fluctuate violently and are cyclical. Changes in regulatory policies applicable to the German industrial user energy sector have led to higher prices for future industrial energy users. The results of our operations are likely to be significantly affected in the past and in the future by these cost increases. Higher prices have increased our demand for liquidity, thus adversely affecting our liquidity and cash flow. Besides, because we use the first onein, first-out (\"FIFO\") Inventory accounting methods, during the period of the decline in raw material prices and the decline in sales prices, the results of our operations during the specific reporting period may be negatively affected, because the lower sales price will be reflected in operating income more quickly than the corresponding cost of raw materials. In order to reduce the risk of price fluctuations in some raw material goods, we used derivatives. In the future, we may decide not to hedge against any of our raw material costs or the results that we may not succeed. In addition, our hedging activities involve credit risks associated with hedging opponents, and the deterioration of financial markets may adversely affect our hedging opponents and their ability to fulfill their obligations to us. The price of crude oil fell, such as during the period from 2014 to 2018 ( In December 31, 2018, it was about 58% lower than the peak level of 2014) , Reducing the cost advantage of natural gas liquids- Ethylene cracking units in North America, such as our Vinyl biscuits. Therefore, our profit margin and cash flow are negatively affected. The reduction in crude oil and gas prices may lead to a reduction in fracking in the United States, which may reduce the supply of raw materials and increase the price of raw materials in our business. Rising gas prices may also adversely affect our ability to export products outside the United States. In addition to this impact on our exports from the United States, the United States is also less competitive. S. In the past, producers have also increased the supply of chemicals in North America because of the U. S. Products that would otherwise be sold overseas are sold domestically, resulting in oversupply and falling prices in North America. We may also face the threat of imported products from countries with cost advantage. In addition, natural gas liquid exports from the United States or greater restrictions on fracking may limit our supply of raw materials in the United States, thus increasing our costs. External factors beyond our control may lead to fluctuations in demand for our products and our prices and profit margins, which may have a negative impact on our operating results and cash flows. External factors beyond our control may lead to fluctuations in raw material prices, demand for our products, product prices and quantities, and a decline in operating profit margins. These factors also amplify the impact of the economic cycle on our business and operational results. Examples of external factors include: general economic conditions, including the United States, Europe and Asia; New production capacity in North America, Europe, Asia and the Middle East; The level of business activity in the industry using our products; Action by competitors; Technological innovation; Currency fluctuations; Rising interest rates; International events and circumstances; War, destruction, terrorism and civil unrest; Government regulation, including the United States, Europe and Asia; Severe weather and natural disasters; Reputation of customers and suppliers. Some of our products are highly dependent on durable goods markets, such as housing and construction markets, which are particularly cyclical in themselves. Weakness of the United States. S. The weak housing market and economy in Europe may adversely affect the demand and profit of our products. If the global economy gets worse in general,S. In particular, the housing market or the deterioration of the European economy, the demand for our products and the results of our operations and cash flows may be adversely affected. We may reduce the production or idle of the facility for a long time, or withdraw from the business because of the high price of raw materials, the oversupply of specific products and/or the lack of demand for that particular product, which makes production uneconomical. Temporary disruptions sometimes last for several quarters, or in some cases for longer periods, resulting in costs incurred by us, including the cost of maintaining and restarting these facilities. Factors such as an increase in raw material costs or a decrease in future demand may lead us to further reduce operating rates, idle facilities or exit from uncompetitive businesses. The occurrence or threat of hostilities or terrorist attacks in the Middle East or elsewhere may adversely affect the economies of the United States, Europe and other developed countries. Lower levels of economic activity may lead to a decline in demand for our products, which may adversely affect our net sales and profit margins and limit our future growth prospects. Fluctuations in crude oil and natural gas prices may also lead to an increase in raw material costs. In addition, crude oil prices continue to fall, for example, from 2014 to 2018, and may lead to a decline in profit margins in the United States. In addition, these risks may lead to more instability in the financial and insurance markets, and may adversely affect our ability to acquire capital and to obtain insurance that we believe is sufficient or that we require under a contract with a third party. We operate on an international scale and face relevant risks, including exchange rate fluctuations, foreign exchange controls, political risks and other risks related to international operations. We operate on an international scale and are at risk of doing business on a global scale. These risks include, but are not limited to, currency exchange rate fluctuations, currency depreciation, and trade barriers ( Among other things, this may have a negative impact on our ability to export products outside the USS. ) Tariffs and duties imposed, restrictions on transfer of funds, changes in legal and regulatory requirements, participation in judicial processes in adverse jurisdictions, economic instability and chaos, political unrest and epidemics. If the U. S. The US government has made certain changes to its foreign trade policy, which may lead to additional trade barriers and tariffs imposed on the US in foreign jurisdictions. Any of these risks can have a negative impact on our operational results. The deterioration of the global economic situation may have a negative impact on our business and financial situation. The deterioration of the global economic situation may have a negative impact on our business and financial situation. When we want or need to enter the capital market, our ability to enter the capital market may be severely restricted, this may affect our flexibility to respond to changing economic and business conditions. In addition, there is no guarantee of additional financing at cost-effective rates. The deterioration of the global economic situation may have an impact on lenders or our customers and suppliers under our revolving credit mechanism, resulting in their failure to meet their obligations to us. In addition, the deterioration of the global economic situation may lead to a decrease in demand for our products, which will have a negative impact on our income and profits. Our failure to compete successfully may reduce our operating profit. Fierce competition in the petrochemical industry. Historically, there have been some mergers, acquisitions, and rotations. Joint ventures within the industry. This restructuring has resulted in fewer but more competitive producers, many of whom are larger than us and have more financial resources than us. Our competitors include some of the world\'s largest chemical companies and joint ventures in the chemical industry. Competition within the petrochemical industry and in the manufacturing of building products is affected by a variety of factors, including: product price; Balance of supply and demand; Innovation in materials, technology and processes; Technical support and customer service; quality; Reliability of supply of raw materials and utilities; Availability of potential alternative materials; And product performance. Catalog changes in a competitive environment can have a significant adverse impact on our business and operations. These changes may include the emergence of new domestic and international competitors; Capacity growth rate of competitors; Changes in customer base due to consolidation; The intensifying of market price competition in China; Competitors introduce new or alternative products; Technological innovation from competitors. Our production facilities handle some volatile and hazardous materials that can adversely affect our operations. We have production bases in the United States, Europe and Asia. Our business is affected by common hazards associated with the manufacture of chemical, plastic and construction products and the use, storage, transportation and disposal of related raw materials, products and wastes, including: leakage and rupture of pipes; explosions; fires; Severe weather and natural disasters; Mechanical failure; Unplanned downtime; Difficulties in labor; Interruption of transportation; Transportation accidents involving our products; Repair complications; Chemical leakage, discharge or release of toxic or harmful substances or gases; Other environmental risks; sabotage; Terrorist attacks; Political turmoil. According to some experts, global climate change may lead to increased hurricane activity in the Gulf of Mexico and other weather and natural disasters worldwide. If this becomes a reality, bad weather and natural disasters can pose a greater risk to our facilities, especially in the state of Luis Anna. All of these hazards can cause personal injury and loss of life, catastrophic damage or damage to property and equipment, environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties. We may be subject to environmental claims from government entities or third parties. During the long-term operation of any of our chemical manufacturing facilities, loss or closure will have a significant adverse impact on us. We retain property, business interruption and accidental injury insurance that we consider to be in line with industry practice, but we cannot fully insure all potential hazards of the business, including risk of war or loss caused by terrorist acts. Due to market conditions, insurance premiums and deductibles for certain insurance policies may increase significantly, and in some cases certain insurance may become unavailable or only if the amount of insurance is reduced If we are to assume a significant responsibility that we do not fully insure, this may have a significant adverse effect on our financial position, operating results or cash flow. 11 catalogue we suffer significant losses due to product liability, personal injury and other claims related to the products we manufacture. In addition, individuals are currently seeking and may continue to seek damage to personal injury or property damage caused by alleged exposure to chemicals or other owned chemicals at our facility, which we control or manufacture. We will also make current and future claims on workplace exposure, workers\' compensation and other matters. With or without merit, any such claim could be a time-consuming, costly defense and could divert the attention and resources of management. We maintain and expect to continue to maintain insurance for product liability, workplace risks, workers\' compensation and other claims, however, the amount and scope of such insurance may be insufficient or unable to pay the claim against our success. In addition, such insurance may become more expensive and difficult to maintain, and we may not be able to obtain it on commercially reasonable terms or at all. The results of any future litigation or claim are inherently unpredictable, but such results may have a significant adverse effect on our financial position, operating results or cash flow. We rely on a limited number of external suppliers for specific raw materials and services. We got a lot of raw materials from several major suppliers. If any of these suppliers are unable to meet their obligations under any existing or future supply agreement, we may be forced to pay a higher price to obtain the necessary raw materials. Any disruption in the supply of raw materials or price increases can have a significant adverse impact on our business and operational results. Under the existing contract, the supplier can choose to modify its relationship at any time because of general economic problems or problems related to the supplier or us. We have any material changes to the terms of the major suppliers, or any material additional requirements of our suppliers, we provide them with additional guarantees in the form of advance payment or letter of credit, may have a significant adverse effect on our financial position, operating results or cash flow. We rely heavily on third-party Shipping, which puts us at risks and costs beyond our control. These risks and costs may have a significant adverse impact on our operations. We rely heavily on railways, barges, pipelines, ships, trucks and other shipping companies to transport raw materials to manufacturing facilities used by our businesses and to ship finished products to our customers.
