WESTLAKE CHEMICAL CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(in millions of dollars, except share amounts and per share data)


1. Basis of Financial Statements
The accompanying unaudited consolidated interim financial statements were prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim periods. Accordingly, certain information and footnotes required for complete financial statements under generally accepted accounting principles in the United States ("U.S. GAAP") have not been included. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Westlake Chemical Corporation (the "Company") included in the annual report on Form 10-K for the fiscal year ended December 31, 2019 (the "2019 Form 10-K"), filed with the SEC on February 19, 2020. These consolidated financial statements have been prepared in conformity with the accounting principles and practices as disclosed in the notes to the consolidated financial statements of the Company for the fiscal year ended December 31, 2019 with the exception of those accounting standards adopted in 2020 as discussed in Note 1.
In the opinion of the Company's management, the accompanying unaudited consolidated interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair statement of the Company's financial position as of June 30, 2020, its results of operations for the three and six months ended June 30, 2020 and 2019, and the changes in its cash position for the six months ended June 30, 2020 and 2019.
Results of operations and changes in cash position for the interim periods presented are not necessarily indicative of the results that will be realized for the fiscal year ending December 31, 2020 or any other interim period. The preparation of consolidated financial statements in conformity with U.S. GAAP 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.
Events surrounding the ongoing coronavirus ("COVID-19") pandemic resulted in widespread adverse impacts on the global economy. The Company experienced significant disruptions in the second quarter of 2020 as the pandemic and its impact on the global economy spread through most of its markets. The Company expected lower demand for certain of its products, which led the Company to proactively temporarily idle production at several of its 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 the Company's products. As a result, all of the Company's idled plants have now recommenced production. Additionally, plant operating rates have generally improved over the course of the second quarter of 2020. As the pandemic and its impacts on the global economy continue, the Company expects to experience further near-term impacts on its business operations. However, the effect 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 ultimate duration, geographic spread and severity of the virus, the actions to contain the virus, the consequences of governmental and other measures designed to prevent the spread of the virus, the development of effective treatments, 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
Income Taxes (ASU No. 2019-12)
In December 2019, the Financial Accounting Standards Board ("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 will be effective for reporting periods beginning after December 15, 2020. Early adoption of this guidance is permitted. The Company is in the process of evaluating the impact that the new accounting guidance will have on the Company's consolidated financial position, results of operations and cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued
(Unaudited)
(in millions of dollars, except share amounts and per share data)

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 as of March 12, 2020 through December 31, 2022. The Company is in the process of evaluating the impact that the new accounting guidance will have on the Company's consolidated financial position, results of operations and cash flows.
Recently Adopted Accounting Standards
Credit Losses (ASU No. 2016-13)
In June 2016, the FASB issued an accounting standards update providing new guidance for the accounting for credit losses on loans and other financial instruments. The new guidance introduces an approach based on expected losses to estimate credit losses on trade receivables, debt securities and certain types of financial instruments. The standard also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. In November 2019, the FASB issued an additional authoritative guidance related to credit losses. The accounting standard became effective for reporting periods beginning after December 15, 2019. The Company adopted this accounting standard effective January 1, 2020 and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Intangibles - Goodwill and Other (ASU No. 2017-04)
In January 2017, the FASB issued an accounting standards update to simplify the subsequent measurement of goodwill. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The accounting standard became effective for reporting periods beginning after December 15, 2019. The Company adopted this accounting standard effective January 1, 2020 and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Fair Value Measurement (ASU No. 2018-13)
In August 2018, the FASB issued an accounting standards update to modify the disclosure requirements on fair value measurements. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date. Most amendments should be applied retrospectively, but certain amendments will be applied prospectively. The accounting standard became effective for reporting periods beginning after December 15, 2019. The Company adopted this accounting standard effective January 1, 2020 and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
2. Financial Instruments
Cash Equivalents
The Company had $0 and $240 of held-to-maturity securities with original maturities of three months or less, primarily consisting of corporate debt securities, classified as cash equivalents at June 30, 2020 and December 31, 2019, respectively. The Company's investments in held-to-maturity securities were held at amortized cost, which approximates fair value.
Restricted Cash and Cash Equivalents
The Company had restricted cash and cash equivalents of $21 and $22 at June 30, 2020 and December 31, 2019, respectively. The Company's restricted cash and cash equivalents are related to balances that are restricted for payment of distributions to certain of the Company's current and former employees and are reflected primarily in other assets, net in the consolidated balance sheets.

The Company performed its annual impairment assessment for the Vinyls reporting units during the second quarter of 2020 and did not identify any impairment. The fair value of the Vinyls reporting units was calculated using both a discounted cash flow methodology and a market value methodology. The discounted cash flow projections were based on a long-term forecast. The forecast was based on prices and spreads projected by third party industry publications, historical results and estimates by management, including its strategic and operational plans. 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. Significant assumptions used in determining the fair value of the reporting unit using the market value methodology included the determination of 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.
The Company performs its annual impairment assessment for the Olefins reporting unit in the fourth quarter or when events or circumstances indicate a reporting unit's carrying value may not be recoverable. There were no events or circumstances indicating that the fair value of the Olefins reporting unit had been reduced below its carrying value during the second quarter of 2020.
During the six months ended June 30, 2020, the Company evaluated various events resulting from the COVID-19 pandemic. Based on the evaluation, the Company does not believe that these events indicate that the fair values of the Company's reporting units have more likely than not fallen below their carrying values as of June 30, 2020. As events and changes in circumstances evolve after June 30, 2020, such events will be considered in the Company's estimates for future periods.

Credit Agreement
The Company has a $1,000 revolving credit facility that is scheduled to mature on July 24, 2023 (the "Credit Agreement"). On March 20, 2020, out of an abundance of caution, the Company borrowed $1,000 under 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. On June 4, 2020, the Company fully repaid the $1,000 of borrowings under the Credit Agreement and, as a result, had no borrowings outstanding under its revolving credit facility as of June 30, 2020. As of June 30, 2020, the Company had no outstanding letters of credit and had $1,000 of borrowing availability under the Credit Agreement. The Credit Agreement contains certain affirmative and negative covenants, including a quarterly total leverage ratio financial maintenance covenant. As of June 30, 2020, the Company was 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.
The Credit Agreement includes a $150 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 commitment for swingline loans to be provided on a same-day basis. The Company may also increase the size of the facility, in increments of at least $25, up to a maximum of $500, subject to certain conditions and if certain lenders agree to commit to such an increase.
3.375% Senior Notes due 2030
On June 12, 2020, the Company completed the registered public offering of $300 aggregate principal amount of its 3.375% Senior Notes due June 15, 2030 (the "3.375% 2030 Senior Notes"). There is no sinking fund and no scheduled amortization of the 3.375% 2030 Senior Notes prior to maturity. The 3.375% 2030 Senior Notes accrue interest from June 12, 2020 at a rate of 3.375% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning December 15, 2020. The indenture and supplemental indenture governing the 3.375% 2030 Senior Notes contain customary events of default and covenants that restrict the Company and certain of its subsidiaries' ability to (1) incur certain secured indebtedness, (2) engage in certain sale-leaseback transactions and (3) consolidate, merge or transfer all or substantially all of its assets. The Company may optionally redeem the 3.375% 2030 Senior Notes in accordance with the terms of the 3.375% 2030 Senior Notes.
6 ½% Senior Notes due 2029
During June 2020, the Company directed the Louisiana Local Government Environmental Facilities and Community Development Authority (the "Authority") to optionally redeem in full $100 aggregate principal amount of the Authority's outstanding Revenue Bonds (Westlake Chemical Corporation Projects) Series 2009A due August 1, 2029 (the "2029 GO Zone Bonds") on August 1, 2020 at a redemption price equal to 100% of the principal amount of the 2029 GO Zone Bonds plus accrued and unpaid interest to the redemption date. The 2029 GO Zone Bonds were offered by the Authority in July 2010 under the Gulf Opportunity Zone Act of 2005 for the benefit of the Company and bore interest at a rate of 6.50% per annum. In connection with the offering of the 2029 GO Zone Bonds in July 2010, the Company issued $100 aggregate principal amount of its 6 ½% senior notes due 2029 (the "6 ½% 2029 GO Zone Senior Notes") to evidence and secure the Company's obligations under the Amended and Restated Loan Agreement relating to the 2029 GO Zone Bonds. On August 1, 2020, the Company purchased the 2029 GO Zone Bonds in lieu of optional redemption. In connection with the purchase of the 2029 GO Zone Bonds by the Company in lieu of optional redemption, the Authority is required to cause the 2029 GO Zone Bonds trustee to surrender the 6 ½% 2029 GO Zone Senior Notes to the Senior Notes trustee for cancellation. A portion of the net proceeds from the issuance of the 3.375% 2030 Senior Notes was used to fund the purchase in lieu of optional redemption of the 2029 GO Zone Bonds.
As of June 30, 2020, the Company was in compliance with all of its long-term debt covenants.
Unamortized debt issuance costs on long-term debt were $31 and $30 at June 30, 2020 and December 31, 2019, respectively.

9. Fair Value Measurements
The Company reports certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). 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.
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 Company's long-term debt instruments, except for the revolving credit facility, 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. The carrying and fair values of the Company's long-term debt are summarized in the table below.

10. Income Taxes
The effective income tax rate was a benefit of 380.0% for the three months ended June 30, 2020 as compared to an expense of 23.2% for the three months ended June 30, 2019. The effective income tax rate for the three months ended June 30, 2020 was a benefit and below the statutory rate of 21.0% primarily due to the income tax rate benefit resulting from the carryback of additional federal net operating loss ("NOL") to taxable years that were taxed at the U.S. corporate tax rate of 35.0% as permitted under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), partially offset by the reduction in the Internal Revenue Code Section 199 ("Section 199") domestic manufacturing deduction, as a result of the NOL carryback, the depletion deduction, the foreign earnings rate differential and the state income tax benefit. The effective income tax rate for the three months ended June 30, 2019 was above the statutory rate of 21.0% primarily due to state taxes.
The effective income tax rate was a benefit of 49.6% for the six months ended June 30, 2020 as compared to an expense of 24.9% for the six months ended June 30, 2019. The effective income tax rate for the six months ended June 30, 2020 was a benefit and below the statutory rate of 21.0% primarily due to the income tax rate benefit resulting from the carryback of federal NOL to taxable years that were taxed at the U.S. corporate tax rate of 35.0% as permitted under the CARES Act, partially offset by the reduction in the Section 199 domestic manufacturing deduction as a result of the NOL carryback, the depletion deduction, the foreign earnings rate differential and the state income tax benefit. The effective income tax rate for the six months ended June 30, 2019 was above the statutory rate of 21.0% primarily due to state taxes and the tax effect related to charges associated with the write-off of certain assets.
On March 27, 2020, the CARES Act was enacted and signed into law. The CARES Act, among other things, permits any federal NOL generated in 2018, 2019 and 2020 to be carried back to each of the five tax years preceding the tax year of the federal NOL to fully offset taxable income to generate a refund of previously paid income taxes. However, any such federal NOL not carried back can be carried forward to fully offset taxable income, but only for the taxable years beginning before January 1, 2021, after which, the federal NOL deduction limitation not to exceed 80.0% of taxable income under the U.S. Tax Cuts and Jobs Act (the "Tax Act") will be reinstated. Federal NOLs generated in 2018, 2019 and 2020 measured at the current U.S. corporate tax rate of 21.0% that are carried back to taxable years prior to the Tax Act to fully offset taxable income taxed at the U.S. corporate tax rate of 35.0% result in an income tax rate benefit. At the end of 2019, the Company generated a federal NOL primarily due to bonus tax depreciation from the Company's investment in LACC, LLC ("LACC"), which is accounted for as an equity method investment. This federal NOL was increased to account for the disallowed interest deduction which originated in 2019 that is no longer disallowed due to the increase in the business interest expense deduction limitation from 30.0% to 50.0% of adjusted taxable income for tax years 2019 and 2020 as permitted under the CARES Act. For the three and six months ended June 30, 2020, the carryback of the federal NOL resulted in a net tax benefit of $6 and $68, respectively, for the Company, primarily from the tax rate difference, partially offset by the reduction in the Section 199 domestic manufacturing deduction.

11. Earnings and Dividends per Share
Earnings 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 each period. Diluted earnings per share include the effects of certain stock options and performance stock units.

Accrued rebates and operating lease liability, which are components of accrued and other liabilities, were $87 and $94 at June 30, 2020, respectively; and $115 and $93 at December 31, 2019, respectively. No other component of accrued and other liabilities was more than five percent of total current liabilities. Accrued liabilities with related parties were $33 and $41 at June 30, 2020 and December 31, 2019, respectively.
Non-cash Investing Activity
The non-cash investing activities related to accruals for capital expenditures were $29 and $9, for the six months ended June 30, 2020 and 2019, respectively.
13. 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.
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. The defendants' joint motion to dismiss the direct purchaser lawsuits was denied, so those cases will proceed with discovery. 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 June 30, 2020 and December 31, 2019, the Company had reserves for environmental contingencies totaling approximately $46 and $47, 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, PolyOne Corporation ("PolyOne"). 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 new 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. The PRPs signed a consent decree for remedial action in March 2020, which is subject to approval by the EPA and the Department of Justice before it is filed with the court. 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 PolyOne. These agreements and 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 PolyOne, and that predecessor assumed Goodrich's indemnification obligations relating to preexisting contamination. In 2003, litigation arose among the Company, Goodrich and PolyOne 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) PolyOne 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 PolyOne 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, PolyOne filed a demand for arbitration. In this proceeding, PolyOne 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 PolyOne paid such costs in full at the beginning of the arbitration hearing.
On July 10, 2018, PolyOne 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 PolyOne's suit. On February 13, 2019, PolyOne 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 PolyOne was responsible for 100% of the allocable costs at issue in the proceeding and that PolyOne would remain responsible for 100% of the costs to operate the existing groundwater remedy at the Calvert City site. In August 2019, PolyOne 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 PolyOne's motion to vacate and affirmed the arbitration final award. PolyOne 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 $70 to $130.
14. Segment Information
The Company operates in two principal operating segments: Olefins and Vinyls. These segments are strategic business units that offer a variety of different products. The Company manages each segment separately as each business requires different technology and marketing strategies.

15. Westlake Chemical Partners LP
In 2014, the Company formed Westlake Chemical Partners LP ("WLKP") to operate, acquire and develop ethylene production facilities and related assets. Also in 2014, WLKP completed its initial public offering of 12,937,500 common units.
At June 30, 2020, WLKP had a 22.8% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), and the Company retained a 77.2% limited partner interest in OpCo and a significant interest in WLKP through the Company's ownership of WLKP's general partner, 40.1% of the limited partner interests (consisting of 14,122,230 common units) and incentive distribution rights.
On October 4, 2018, WLKP and Westlake Partners GP, the general partner of WLKP, 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 WLKP's common units, from time to time, up to an aggregate offering amount of $50. This Equity Distribution Agreement was amended on February 28, 2020 to reference a new shelf registration for utilization under this agreement. No common units were issued under this program as of June 30, 2020.
Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
This discussion and analysis should be read in conjunction with information contained in the accompanying unaudited consolidated interim financial statements of Westlake Chemical Corporation ("Westlake" or the "Company") and the notes thereto and the consolidated financial statements and notes thereto of Westlake Chemical Corporation included in Westlake Chemical Corporation's Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the "2019 Form 10-K"). The following discussion contains forward-looking statements. Please read "Forward-Looking Statements" for a discussion of limitations inherent in such statements.
We are a vertically integrated global manufacturer and marketer of basic chemicals, vinyls, polymers and building products. Our two principal operating segments are Olefins and Vinyls. We use the majority of our internally-produced basic chemicals to produce higher value-added chemicals, polymers and building products.
Consumption of the basic chemicals that we manufacture in the commodity portions of our olefins and vinyls processes has increased significantly since we began operations in 1986. Our olefins and vinyls products are some of the most widely used chemicals in the world and are upgraded into a wide variety of higher value-added chemical products used in many end-markets. 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.

19



Ethane-based ethylene producers have in the recent past 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 Olefins segment during such periods. However, we have seen a significant reduction in the cost advantage enjoyed by North American ethane-based ethylene producers due to lower crude oil prices from the third quarter of 2014 through the second quarter of 2020, which has resulted in reduced prices and lower margins for our Olefins segment. Further, our Olefins segment has experienced lower profitability in recent periods due to several new ethylene and polyethylene capacity additions in North America and Asia that have led to additional supply of ethylene and polyethylene. In recent months, we have seen volatility in ethane and ethylene prices, primarily due to changes in demand resulting from the coronavirus ("COVID-19") pandemic, anticipated timing for certain new ethylene capacity additions and availability of natural gas liquids, as well as fluctuation in the price of crude oil. Looking forward, new ethylene and polyethylene capacity additions in North America, Asia and the Middle East will add additional supply and may continue to contribute to periods of lower profitability in our Olefins segment.
Since late 2010, the PVC industry in the U.S. has experienced an increase in PVC resin exports, driven largely by more competitive feedstock and energy cost positions in the U.S. As a consequence, the U.S. PVC resin industry operating rates have improved since 2010. Westlake is the second-largest chlor-alkali producer and the second-largest PVC producer in the world. Globally, there were large chlor-alkali capacity additions between 2008 and 2015 resulting in excess capacity and lower industry operating rates which exerted downward pressure on caustic soda pricing. From 2015 through the end of 2018, the capacity additions have been outpaced by an increase in demand driven by improving economic growth and U.S. producers' competitive export position, which resulted in improved operating rates and caustic soda pricing. Since the second half of 2018, the uncertainties surrounding international trade have impacted both domestic and export prices for our products. In addition, COVID-19 has negatively impacted demand for our products both in the domestic as well as in the export markets in recent months.
Recent Developments
Recent Developments Affecting 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. While demand for some of our products used in cleaning, packaging and medical applications and manufacturing continues 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 have now recommenced production. While plant operating rates have improved over the course of the second quarter of 2020, plant operating rates remain below our normal seasonal operating rates due to continuing demand and price pressures. 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 resulting disruptions to our business operations in the near future.
Our first priority in our response to this crisis has been the health and safety of our employees and those of our customers and vendors. We have implemented preventative measures and developed corporate and regional response plans to minimize unnecessary risk of exposure. 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 the Center for Disease Control and Prevention, the World Health Organization and other governmental and regulatory authorities.
Though the government restrictions across the world generally started to ease in the later part of the second quarter of 2020, 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, such as large-scale travel bans and restrictions, border closures, quarantines, shelter-in-place orders and business and government shutdowns (whether through a continuation of existing measures or the re-imposition of prior measures). Restrictions of this nature have caused, and may continue to cause us and our customers to experience reduced demand and operational delays. Lockdowns across the world and curtailed business activities specifically in transportation, construction, automotive and oil and gas related activities have resulted in and may continue to result in an oversupplied market. We continue to see weakness in demand for some of our products due to the continuing impact of restrictions on business activities.

20



Due to the sudden collapse of crude oil prices in early March 2020, the cost advantage of North American ethane-based ethylene producers over naphtha-based ethylene producers has been significantly eroded. We started seeing impact from this erosion towards the end of the first quarter of 2020. Crude oil prices have recovered somewhat since the later half of the second quarter of 2020. If this trend is not sustained in the future, it could continue to result in reduced prices and lower margins for our Olefins segment and some of our products in the Vinyls segment. In addition, our Olefins segment has been impacted by the addition of new ethylene production capacity in recent months.
We have taken proactive actions to respond to the challenges presented by the conditions described above and minimize the impact to our business. We have implemented strategies to reduce costs, increase operational efficiencies, maintain strong liquidity and lower our capital spending. We expect to reduce our capital spending in 2020 to be in the range of $500 million to $550 million. Additionally, we deferred the planned turnaround at our Petro 2 ethylene unit and associated maintenance cost into the first half of 2021. The turnaround is expected to last 60 days.
In addition, as of June 30, 2020, we had $1,109 million of cash and cash equivalents on our consolidated balance sheet, which remains available to support our operations, in addition to the $1 billion of availability under the Credit Agreement. Our borrowings of $1 billion under the Credit Agreement on March 20, 2020 were fully repaid on June 4, 2020.
The impact that COVID-19 will have on our business, cash flows, liquidity, financial condition and results of operations will depend on future developments, including, among others, the ultimate geographic spread and severity of the virus, the consequences of governmental and other measures designed to prevent the spread of the virus, the development of effective treatments, the duration of the outbreak, actions taken by governmental authorities, customers, suppliers and other third parties, workforce availability, and the timing and extent to which normal economic and operating conditions resume.
CARES Act
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was enacted and signed into law. The CARES Act, among other things, permits any federal net operating loss ("NOL") generated in 2018, 2019 and 2020 to be carried back to each of the five tax years preceding the tax year of the federal NOL to fully offset taxable income to generate a refund of previously paid income taxes. However, any such federal NOL not carried back can be carried forward to fully offset taxable income, but only for the taxable years beginning before January 1, 2021, after which, the federal NOL deduction limitation not to exceed 80% of taxable income under the U.S. Tax Cuts and Jobs Act (the "Tax Act") will be reinstated. Federal NOLs generated in 2018, 2019 and 2020 measured at the current U.S. corporate tax rate of 21% that are carried back to taxable years prior to the Tax Act to fully offset taxable income taxed at the U.S. corporate tax rate of 35% result in an income tax rate benefit. At the end of 2019, we generated a federal NOL primarily due to bonus tax depreciation from the Company's investment in LACC, LLC ("LACC"), which is accounted for as an equity method investment. This federal NOL was increased to account for the disallowed interest deduction which originated in 2019 that is no longer disallowed due to the increase in the business interest expense deduction limitation from 30% to 50% of adjusted taxable income for tax years 2019 and 2020 as permitted under the CARES Act. For the three and six months ended June 30, 2020, the carryback of the federal NOL resulted in a net tax benefit of $6 million and $68 million, respectively, for the Company, primarily from the tax rate difference, partially offset by the reduction in the Internal Revenue Code Section 199 ("Section 199") domestic manufacturing deduction.
3.375% Senior Notes due 2030
On June 12, 2020, we completed the registered public offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes. See "Liquidity and Capital Resources—Debt" below and Note 7 to the consolidated financial statements included in this Form 10-Q for more information.
6 ½% Senior Notes due 2029
During June 2020, the Company directed the Louisiana Local Government Environmental Facilities and Community Development Authority (the "Authority") to optionally redeem in full $100 million aggregate principal amount of the 2029 GO Zone Bonds on August 1, 2020 at a redemption price equal to 100% of the principal amount of the 2029 GO Zone Bonds plus accrued and unpaid interest to the redemption date. The 2029 GO Zone Bonds were offered by the Authority in July 2010 under the Gulf Opportunity Zone Act of 2005 (the "GO Zone Act") for the benefit of the Company and bore interest at a rate of 6.50% per annum. In connection with the offering of the 2029 GO Zone Bonds in July 2010, the Company issued $100 million aggregate principal amount of the 6 ½% 2029 GO Zone Senior Notes to evidence and secure the Company's obligations under the Amended and Restated Loan Agreement relating to the 2029 GO Zone Bonds. On August 1, 2020, the Company purchased the 2029 GO Zone Bonds in lieu of optional redemption. In connection with the purchase of the 2029 GO Zone Bonds by the Company in lieu of optional redemption, the Authority is required to cause the 2029 GO Zone Bonds trustee to surrender the 6 ½% 2029 GO Zone Senior Notes to the Senior Notes trustee for cancellation. We used a portion of the net proceeds from the issuance of the 3.375% 2030 Senior Notes to fund the purchase in lieu of optional redemption of the 2029 GO Zone Bonds.

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 Securities and Exchange Commission ("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-Q are not substitutes for the GAAP measures of earnings and cash flows.
EBITDA is included in this Form 10-Q 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.
A reconciliation of EBITDA to net income, income from operations and net cash provided by operating activities is included in the "Results of Operations" section below.

Summary
For the quarter ended June 30, 2020, net income attributable to Westlake was $15 million, or $0.11 per diluted share, on net sales of $1,709 million. This represents a decrease in net income attributable to Westlake of $104 million, or $0.81 per diluted share, compared to the quarter ended June 30, 2019 net income attributable to Westlake of $119 million, or $0.92 per diluted share, on net sales of $2,144 million. The decrease in net income was primarily due to the global economic impact from the COVID-19 pandemic and the significant drop in crude oil prices, which reduced North American ethylene industry feedstock competitiveness. The impact of reduced demand resulting from the pandemic and lower crude oil prices led to lower global sales prices for our major products and lower sales volumes for caustic soda and downstream vinyl products. Net income was also lower in the quarter ended June 30, 2020 due to higher interest expense related to additional borrowings during the quarter. These decreases were partially offset by the income tax rate benefit of $6 million, or $0.05 per diluted share, resulting from the carryback of federal net operating losses permitted by the CARES Act and lower ethane feedstock costs, fuel costs, operating costs, costs associated with planned turnarounds and selling, general and administrative expenses. Income from operations for the quarter ended June 30, 2020 was $36 million, a $158 million decrease from income from operations of $194 million for the quarter ended June 30, 2019. The decrease in income from operations was primarily due to lower global sales prices for our major products and lower sales volumes for caustic soda and downstream vinyl products, partially offset by lower ethane feedstock costs, fuel costs, operating costs, costs associated with planned turnarounds and selling, general and administrative expenses. Net sales for the quarter ended June 30, 2020 decreased by $435 million compared to net sales for the quarter ended June 30, 2019, mainly due to lower sales prices for our major products and lower sales volumes for caustic soda and vinyls downstream products, partially offset by higher sales volumes for polyethylene.
For the six months ended June 30, 2020, net income attributable to Westlake was $160 million, or $1.24 per diluted share, on net sales of $3,641 million. This represents a decrease in net income attributable to Westlake of $31 million, or $0.23 per diluted share, compared to the six months ended June 30, 2019 net income attributable to Westlake of $191 million, or $1.47 per diluted share, on net sales of $4,169 million. The decrease in net income was primarily due to lower global sales prices for our major products and lower sales volumes for caustic soda resulting from the impact of the COVID-19 pandemic and lower crude oil prices. Net income was also lower in the six months ended June 30, 2020 due to higher interest expense related to additional borrowings during the period. These decreases were partially offset by the income tax rate benefit of $68 million, or $0.53 per diluted share, resulting from the carryback of federal net operating losses permitted by the CARES Act and lower ethane feedstock costs, fuel costs, operating costs, costs associated with planned turnarounds, restructuring, transaction and integration-related costs and selling, general and administrative expenses. Income from operations for the six months ended June 30, 2020 was $172 million, a $156 million decrease from income from operations of $328 million for the six months ended June 30, 2019. The decrease in income from operations was primarily due to lower global sales prices for our major products and lower sales volume for caustic soda, partially offset by lower ethane feedstock costs, fuel costs, operating costs, costs associated with planned turnarounds, restructuring, transaction and integration-related costs and selling, general and administrative costs. Net sales for the six months ended June 30, 2020 decreased by $528 million compared to net sales for the six months ended June 30, 2019, mainly due to lower sales prices for our major products and lower sales volumes for caustic soda, partially offset by higher sales volumes for polyethylene.
RESULTS OF OPERATIONS
Second Quarter 2020 Compared with Second Quarter 2019
Net Sales. Net sales decreased by $435 million, or 20%, to $1,709 million in the second quarter of 2020 from $2,144 million in the second quarter of 2019, primarily attributable to lower sales prices for our major products and lower sales volumes for caustic soda and downstream vinyl products, partially offset by higher sales volumes for polyethylene. Average sales prices for the second quarter of 2020 decreased by 15% as compared to the second quarter of 2019, primarily due to the impact of the COVID-19 pandemic and lower crude oil prices. Sales volumes decreased by 6% for the second quarter of 2020 as compared to the second quarter of 2019.
Gross Profit. Gross profit margin percentage was 10% in the second quarter of 2020 as compared to 16% in the second quarter of 2019. The decrease in gross profit margin was primarily due to a decrease in prices for our major products, partially offset by lower feedstock and operating costs.
Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $13 million to $104 million in the second quarter of 2020 as compared to $117 million in the second quarter of 2019. This decrease was mainly due to lower employee compensation and selling expenses.
Amortization of Intangibles. Amortization expense was $27 million in the second quarter of 2020, which was comparable to the second quarter of 2019.

26



Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-related costs were $2 million in the second quarter of 2020, which was comparable to the second quarter of 2019.
Interest Expense. Interest expense increased by $12 million to $40 million in the second quarter of 2020 from $28 million in the second quarter of 2019, primarily as a result of higher average debt outstanding in the second quarter of 2020 as compared to the second quarter of 2019. The higher average debt balance in the second quarter of 2020 was primarily due to the borrowings of $1 billion under our revolving credit facility in March 2020 (which were fully repaid in June 2020), the issuance of the $300 million aggregate principal amount of 3.375% 2030 Senior Notes in June 2020 and the issuance of the €700 million aggregate principal amount of 1.625% 2029 Senior Notes in July 2019. See "Liquidity and Capital Resources—Debt" below and Note 7 to the consolidated financial statements included in this Form 10-Q for further discussion of our indebtedness.
Other Income, Net. Other income, net increased by $7 million to $9 million in the second quarter of 2020, as compared to $2 million in the second quarter of 2019, primarily due to higher income from unconsolidated subsidiaries and gains related to pension benefits and foreign exchange fluctuations.
Income Taxes. The effective income tax rate was a benefit of 380.0% for the second quarter of 2020 as compared to an expense of 23.2% for the second quarter of 2019. The change in effective tax rate in the second quarter of 2020 as compared to the second quarter of 2019 was primarily due to the income tax rate benefit resulting from the carryback of federal net operating loss 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, the depletion deduction, the foreign earnings rate differential and the state income tax benefit.
Olefins Segment
Net Sales. Net sales for the Olefins segment decreased by $116 million, or 24%, to $361 million in the second quarter of 2020 from $477 million in the second quarter of 2019. The decrease was mainly due to lower sales prices for our major products, partially offset by higher sales volumes for polyethylene. Average sales prices for the Olefins segment decreased by 25% in the second quarter of 2020 as compared to the second quarter of 2019. Sales volumes for the Olefins segment increased by 1% in the second quarter of 2020 as compared to the second quarter of 2019, primarily due to increased polyethylene export sales.
Income from Operations. Income from operations for the Olefins segment decreased by $57 million to $25 million in the second quarter of 2020 from $82 million in the second quarter of 2019. This decrease in income from operations was primarily due to lower sales prices for polyethylene as a result of lower crude oil prices and slower global economic activities due to the COVID-19 pandemic, partially offset by higher polyethylene sales volumes and lower feedstock and fuel costs. Trading activity for the second quarter of 2020 resulted in a gain of approximately $3 million as compared to a loss of $7 million for the second quarter of 2019.
Vinyls Segment
Net Sales. Net sales for the Vinyls segment decreased by $319 million, or 19%, to $1,348 million in the second quarter of 2020 from $1,667 million in the second quarter of 2019. The decrease was primarily due to lower sales prices for our major products and lower sales volumes for caustic soda and downstream vinyl products, as compared to the prior-year period. Average sales prices for the Vinyls segment decreased by 12% in the second quarter of 2020, as compared to the second quarter of 2019. Sales volumes for the Vinyls segment decreased by 8% in the second quarter of 2020 as compared to the second quarter of 2019.
Income from Operations. Income from operations for the Vinyls segment decreased by $109 million to $20 million in the second quarter of 2020 from $129 million in the second quarter of 2019. This decrease in income from operations versus the prior-year period was primarily due to the continued impact of COVID-19 and a sharp drop in global oil prices, which led to lower sales prices for our major products, and lower sales volumes for caustic soda and downstream vinyl products. The decrease was partially offset by lower ethane feedstock costs, fuel costs, operating costs and costs associated with planned turnarounds.

27



Six Months Ended June 30, 2020 Compared with Six Months Ended June 30, 2019
Net Sales. Net sales decreased by $528 million, or 13%, to $3,641 million in the six months ended June 30, 2020 from $4,169 million in the six months ended June 30, 2019, primarily attributable to lower sales prices for our major products and lower sales volumes for caustic soda, partially offset by higher sales volumes for polyethylene. Average sales prices for the six months ended June 30, 2020 decreased by 12% as compared to the six months ended June 30, 2019 due to slower global economic activities as a result of the COVID-19 pandemic and lower crude oil prices. Sales volumes decreased by 1% for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.
Gross Profit. Gross profit margin percentage was 12% in the six months ended June 30, 2020 as compared to 15% in the six months ended June 30, 2019. The decrease in gross profit margin was primarily due to a decrease in prices for our major products, partially offset by lower feedstock and operating costs.
Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $9 million to $224 million in the six months ended June 30, 2020 as compared to $233 million in the six months ended June 30, 2019. This decrease was mainly due to lower employee compensation and selling expenses.
Amortization of Intangibles. Amortization expense was $54 million in the six months ended June 30, 2020, which was comparable to the six months ended June 30, 2019.
Restructuring, Transaction and Integration-related Costs. Restructuring, transaction and integration-related costs in the six months ended June 30, 2020 were $2 million as compared to $24 million in the six months ended June 30, 2019. The restructuring, transaction and integration-related costs for the 2019 period primarily consisted of restructuring expenses of $19 million and acquisition and integration-related costs of $5 million.
Interest Expense. Interest expense increased by $13 million to $71 million in the six months ended June 30, 2020 from $58 million in the six months ended June 30, 2019, primarily as a result of higher average debt outstanding in the six months ended June 30, 2020 as compared to the six months ended June 30, 2019. The higher average debt balance in the 2020 period was primarily due to the borrowings of $1 billion under our revolving credit facility in March 2020 (which were fully repaid in June 2020), the issuance of the $300 million aggregate principal amount of 3.375% 2030 Senior Notes in June 2020 and the issuance of the €700 million aggregate principal amount of 1.625% 2029 Senior Notes in July 2019. See "Liquidity and Capital Resources—Debt" below and Note 7 to the consolidated financial statements included in this Form 10-Q for further discussion of our indebtedness.
Other Income, Net. Other income, net increased by $9 million to $20 million in the six months ended June 30, 2020, as compared to $11 million in the six months ended June 30, 2019, primarily due to higher income from unconsolidated subsidiaries and gains related to pension benefits and foreign exchange fluctuations.
Income Taxes. The effective income tax rate was a benefit of 49.6% for the six months ended June 30, 2020 as compared to an expense of 24.9% for the six months ended June 30, 2019. The change in effective tax rate in the six months ended June 30, 2020 as compared to the six months ended June 30, 2019 was primarily due to the income tax rate benefit resulting from the carryback of federal net operating loss 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, the depletion deduction, the foreign earnings rate differential and the state income tax benefit.
Olefins Segment
Net Sales. Net sales for the Olefins segment decreased by $148 million, or 16%, to $788 million in the six months ended June 30, 2020 from $936 million in the six months ended June 30, 2019. The decrease was mainly due to lower sales prices for our major products, partially offset by higher sales volumes for polyethylene. Average sales prices for the Olefins segment decreased by 18% in the six months ended June 30, 2020 as compared to the six months ended June 30, 2019. Sales volumes for the Olefins segment increased by 2% in the six months ended June 30, 2020 as compared to the six months ended June 30, 2019, primarily due to increased polyethylene export sales.
Income from Operations. Income from operations for the Olefins segment decreased by $32 million to $87 million in the six months ended June 30, 2020 from $119 million in the six months ended June 30, 2019. This decrease in income from operations was primarily due to lower sales prices for our major products, mainly resulting from lower crude oil prices and slower global economic activities due to the COVID-19 pandemic, partially offset by higher polyethylene sales volumes and lower ethane feedstock costs and fuel costs. Trading activity for the six months ended June 30, 2020 resulted in a gain of approximately $1 million as compared to a loss of $11 million for the six months ended June 30, 2019.

28



Vinyls Segment
Net Sales. Net sales for the Vinyls segment decreased by $380 million, or 12%, to $2,853 million in the six months ended June 30, 2020 from $3,233 million in the six months ended June 30, 2019. The decrease was mainly due to lower sales prices for our major products and lower sales volumes for caustic soda, as compared to the prior-year period. Average sales prices for the Vinyls segment decreased by 10% in the six months ended June 30, 2020, as compared to the six months ended June 30, 2019. Sales volumes for the Vinyls segment decreased by 2% in the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.
Income from Operations. Income from operations for the Vinyls segment decreased by $137 million to $93 million in the six months ended June 30, 2020 from $230 million in the six months ended June 30, 2019. This decrease in income from operations was primarily due to lower sales prices for our major products and lower sales volumes for caustic soda, mainly resulting from lower crude oil prices and slower global economic activities due to the COVID-19 pandemic, partially offset by lower ethane feedstock costs, fuel costs, operating costs and costs associated with planned turnarounds and the contribution from our ethylene joint venture with Lotte Chemical in Lake Charles, Louisiana, which began commercial operations in the second half of 2019.
CASH FLOW DISCUSSION FOR THE SIX MONTHS ENDED JUNE 30, 2020 AND 2019
Cash Flows
Operating Activities
Operating activities provided cash of $509 million in the first six months of 2020 compared to cash provided by operating activities of $467 million in the first six months of 2019. The $42 million increase in cash flows from operating activities was mainly due to a favorable change in the trade customers balance, partially offset by a decrease in income from operations due to factors as discussed in "Summary" above and other 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 $124 million in the first six months of 2020, compared to $104 million of cash used in the first six months of 2019, an unfavorable change of $20 million. The majority of the unfavorable changes were due to the change in accounts receivable which was driven by the expected income tax refund resulting from the CARES Act, as discussed previously, partially offset by the favorable change in the trade customers balance. Other changes in working capital were due to lower inventories and accounts payable, primarily driven by the changes in inventory levels and operating activities.
Investing Activities
Net cash used for investing activities in the first six months of 2020 was $260 million as compared to net cash used for investing activities of $763 million in the first six months of 2019. Capital expenditures were $291 million in the first six months of 2020, which was lower by $120 million as compared to $411 million in the first six months of 2019. The decrease in capital expenditures was primarily due to lower expenses for expansion projects in the first six months of 2020, as compared to the first six months of 2019. Capital expenditures in the first six months of 2020 and 2019 were primarily related to projects to improve production capacity or reduce costs, maintenance and safety projects and environmental projects at our various facilities. In the first six months of 2020, we received $39 million from our joint venture, LACC, representing a return of investment. The other investing activities in the first six months of 2019 were acquisitions for $314 million, in the aggregate, net of acquired cash balances, and funding of $42 million for LACC.
Financing Activities
Net cash provided by financing activities during the first six months of 2020 was $131 million as compared to net cash used for financing activities of $48 million in the first six months of 2019. In March 2020, out of an abundance of caution, we borrowed $1,000 million under our revolving credit facility, which was fully repaid in June 2020. We also completed the registered public offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes in June 2020. See "Liquidity and Capital Resources—Debt" below for more information. The remaining activities during the first six months of 2020 were primarily related to the $68 million payment of cash dividends, the $29 million payment of cash distributions to noncontrolling interests, repurchases of our common stock of $54 million, and the $14 million repayment of short-term notes payable. In the first six months of 2019, we received proceeds of $63 million from the issuance of Westlake Chemical Partners LP ("WLKP") common units. The remaining activities during the first six months of 2019 were primarily related to the $65 million payment of cash dividends, the $30 million payment of cash distributions to noncontrolling interests, and $20 million of repurchases of our common stock.

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 June 30, 2020, we had repurchased 6,776,913 shares of our common stock for an aggregate purchase price of approximately $399 million under the 2014 Program. During the six months ended June 30, 2020, we repurchased 995,529 shares of our common stock 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, WLKP and Westlake Partners GP, the general partner of WLKP, 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 WLKP's 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 2018, 2019 or in the six months ended June 30, 2020.
On March 20, 2020, out of an abundance of caution, we borrowed $1 billion under our $1 billion revolving credit facility that is scheduled to mature on July 24, 2023 (the "Credit Agreement") to maintain financial flexibility in light of current uncertainty in the global markets caused by COVID-19. On June 4, 2020, we fully repaid the $1 billion of borrowings under the Credit Agreement and, as a result, have no current borrowings outstanding under our revolving credit facility.
On June 12, 2020, we completed the registered public offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes. See "Liquidity and Capital Resources—Debt" below for more information.
During June 2020, the Company directed the Authority to optionally redeem in full $100 million aggregate principal amount of the 2029 GO Zone Bonds on August 1, 2020 at a redemption price equal to 100% of the principal amount of the 2029 GO Zone Bonds plus accrued and unpaid interest to the redemption date. The 2029 GO Zone Bonds were offered by the Authority in July 2010 under the GO Zone Act for the benefit of the Company and bore interest at a rate of 6.50% per annum. In connection with the offering of the 2029 GO Zone Bonds in July 2010, the Company issued $100 million aggregate principal amount of the 6 ½% 2029 GO Zone Senior Notes to evidence and secure the Company's obligations under the Amended and Restated Loan Agreement relating to the 2029 GO Zone Bonds. On August 1, 2020, the Company purchased the 2029 GO Zone Bonds in lieu of optional redemption. In connection with the purchase of the 2029 GO Zone Bonds by the Company in lieu of optional redemption, the Authority is required to cause the 2029 GO Zone Bonds trustee to surrender the 6 ½% 2029 GO Zone Senior Notes to the Senior Notes trustee for cancellation. We used a portion of the net proceeds from the issuance of the 3.375% 2030 Senior Notes to fund the purchase in lieu of optional redemption of the 2029 GO Zone Bonds.
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 or potential acquisitions would 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.
Cash and Cash Equivalents
As of June 30, 2020, our cash and cash equivalents totaled $1,109 million.

30



Debt
As of June 30, 2020, our indebtedness totaled $3.7 billion. See Note 7 to the consolidated financial statements appearing elsewhere in this Form 10-Q for a discussion of our long-term indebtedness. Defined terms used in this section have the definitions assigned to such terms in Note 7 to the consolidated financial statements included in Item 1 of this Form 10-Q.
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 Credit Agreement and, in connection therewith, terminated the existing $1 billion revolving credit facility that was scheduled to mature on August 23, 2021 (the "Prior 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. At June 30, 2020, we had no borrowings outstanding under the Credit Agreement. As of June 30, 2020, we had no outstanding letters of credit and had $1 billion of borrowing availability (absent an exercise of the accordion feature) under the Credit Agreement. The Credit Agreement contains certain affirmative and negative covenants, including a quarterly total leverage ratio financial maintenance covenant. As of June 30, 2020, 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.
GO Zone Bonds and IKE Zone Bonds
In November 2017, the Authority completed the offering of $250 million aggregate principal amount of 3.50% tax-exempt revenue refunding bonds due November 1, 2032 (the "Refunding Bonds"), the net proceeds of which were used to redeem $250 million aggregate principal amount of the Authority's 6 ¾% tax-exempt revenue bonds due November 1, 2032 issued by the Authority under the GO Zone Act in December 2007. In connection with the issuance of the Refunding Bonds, we issued $250 million of the 3.5% 2032 GO Zone Refunding Senior Notes. The Refunding Bonds are subject to optional redemption by the Authority upon the direction of the Company at any time on or after November 1, 2027, for 100% of the principal plus accrued interest.
In July 2010, the Authority completed the reoffering of $100 million of the 2029 GO Zone Bonds. In connection with the reoffering of the 2029 GO Zone Bonds, we issued $100 million of the 6 ½% 2029 GO Zone Senior Notes. In December 2010, the Authority issued $89 million of the 6 ½% 2035 GO Zone Bonds. In connection with the issuance of the 6 ½% 2035 GO Zone Bonds, we issued $89 million of the 6 ½% 2035 GO Zone Senior Notes. In December 2010, the Authority completed the offering of $65 million of the 6 ½% 2035 IKE Zone Bonds under Section 704 of the Emergency Economic Stabilization Act of 2008 (the "IKE Zone Act"). In connection with the issuance of the 6 ½% 2035 IKE Zone Bonds, we issued $65 million of the 6 ½% 2035 IKE Zone Senior Notes.

31



The 6 ½% 2035 GO Zone Bonds and the 6 ½% 2035 IKE Zone Bonds are subject to optional redemption by the Authority upon the direction of the Company at any time prior to November 1, 2020 for 100% of the principal plus accrued interest and a discounted "make whole" payment. On or after November 1, 2020, the 6 ½% 2035 GO Zone Bonds and the 6 ½% 2035 IKE Zone Bonds are subject to optional redemption by the Authority upon the direction of the Company for 100% of the principal plus accrued interest.
In June 2020, we directed the Authority to optionally redeem in full $100 million aggregate principal amount of the outstanding 2029 GO Zone Bonds on August 1, 2020 at a redemption price equal to 100% of the principal amount of the 2029 GO Zone Bonds plus accrued and unpaid interest to the redemption date. In connection with the purchase in lieu of redemption of the 2029 GO Zone Bonds, the Authority is required to cause the GO Zone Bonds trustee to surrender the 6 ½% 2029 GO Zone Senior Notes to the Senior Notes trustee for cancellation. On August 1, 2020, the Company purchased the 2029 GO Zone Bonds in lieu of optional redemption.
We currently plan on directing the Authority to optionally redeem all of the outstanding 6 ½% 2035 GO Zone Bonds and the 6 ½% 2035 IKE Zone Bonds on or about November 1, 2020 at a redemption price of 100% of the principal amount plus accrued but unpaid interest, if any, to the redemption date. We plan on purchasing the 6 ½% 2035 GO Zone Bonds and the 6 ½% 2035 IKE Zone Bonds in lieu of redemption and using a portion of the net proceeds from the issuance of the 3.375% 2030 Senior Notes to fund the purchase in lieu of redemption.
3.60% Senior Notes due 2022
In July 2012, we issued $250 million aggregate principal amount of the 3.60% 2022 Senior Notes. We may optionally redeem the 3.60% 2022 Senior Notes at any time and from time to time prior to April 15, 2022 (three months prior to the maturity date) for 100% of the principal plus accrued interest and a discounted "make whole" payment. On or after April 15, 2022, we may optionally redeem the 3.60% 2022 Senior Notes for 100% of the principal plus accrued interest. The holders of the 3.60% 2022 Senior Notes may require us to repurchase the 3.60% 2022 Senior Notes at a price of 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase, upon the occurrence of both a "change of control" and, within 60 days of such change of control, a "below investment grade rating event" (as such terms are defined in the indenture and supplemental indenture governing the 3.60% 2022 Senior Notes).
Revenue Bonds
In December 1997, we entered into a loan agreement with a public trust established for public purposes for the benefit of the Parish of Calcasieu, Louisiana. The public trust issued $11 million principal amount of tax-exempt waste disposal revenue bonds in order to finance our construction of waste disposal facilities for an ethylene plant. The waste disposal revenue bonds expire in December 2027 and are subject to redemption and mandatory tender for purchase prior to maturity under certain conditions. Interest on the waste disposal revenue bonds accrues at a rate determined by a remarketing agent and is payable quarterly. The interest rate on the waste disposal revenue bonds at June 30, 2020 was 0.22% and at December 31, 2019 was 1.78%.
1.625% Senior Notes due 2029
In July 2019, we completed the registered public offering of €700 million aggregate principal amount of the 1.625% Senior Notes due July 17, 2029. The Company received approximately $779 million of net proceeds from the offering. We may optionally redeem the 1.625% 2029 Senior Notes at any time and from time to time prior to April 17, 2029 (three months prior to the maturity date) for 100% of the principal plus accrued interest and a discounted "make whole" payment. On or after April 17, 2029, we may optionally redeem the 1.625% 2029 Senior Notes for 100% of the principal amount plus accrued interest. The holders of the 1.625% 2029 Senior Notes may require us to repurchase the 2029 Senior Notes at a price of 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase, upon the occurrence of both a "change of control" and, within 60 days of such change of control, a "below investment grade rating event" (as such terms are defined in the indenture and supplemental indenture governing the 1.625% 2029 Senior Notes).

32



3.375% Senior Notes due 2030
On June 12, 2020, we completed the registered public offering of $300 million aggregate principal amount of the 3.375% 2030 Senior Notes. We may optionally redeem the 3.375% 2030 Senior Notes at any time and from time to time prior to March 15, 2030 (three months prior to the maturity date) for 100% of the principal plus accrued interest and a discount "make whole" payment. On or after March 15, 2030, we may optionally redeem the 3.375% 2030 Senior Notes for 100% of the principal amount plus accrued interest. The holders of the 3.375% 2030 Senior Notes may require us to repurchase the 3.375% 2030 Senior Notes at a price of 101% of the principal amount, plus accrued and unpaid interest to, but not including, the date of repurchase, upon the occurrence of both a "change of control" and, within 60 days of such change of control, a "below investment grade rating event" (as such terms are defined in the indenture and supplemental indenture governing the 3.375% 2030 Senior Notes).
3.60% Senior Notes due 2026 and 5.0% Senior Notes due 2046
In August 2016, we completed the private offering of $750 million aggregate principal amount of our 3.60% 2026 Senior Notes and $700 million aggregate principal amount of our 5.0% 2046 Senior Notes. In March 2017, the Company commenced registered exchange offers to exchange the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes for new notes that are identical in all material respects to the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes, except that the offer and issuance of the new Securities and Exchange Commission ("SEC")-registered notes have been registered under the Securities Act of 1933, as amended (the "Securities Act"). The exchange offers expired on April 24, 2017, and approximately 99.97% of the 3.60% 2026 Senior Notes and 100% of the 5.0% 2046 Senior Notes were exchanged. The notes that were not exchanged in the exchange offers have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the U.S. absent registration or an applicable exemption from registration requirements or a transaction not subject to the registration requirements of the Securities Act or any state securities law.
4.375% Senior Notes due 2047
In November 2017, we completed the registered public offering of $500 million aggregate principal amount of 4.375% Senior Notes due November 15, 2047. We may optionally redeem the 4.375% 2047 Senior Notes at any time and from time to time prior to May 15, 2047 (six months prior to the maturity date) for 100% of the principal plus accrued interest and a discounted "make whole" payment. On or after May 15, 2047, we may optionally redeem the 4.375% 2047 Senior Notes for 100% of the principal amount plus accrued interest.

The indenture and supplemental indentures governing the 3.60% 2022 Senior Notes, the 3.60% 2026 Senior Notes, the 1.625% 2029 Senior Notes, the 3.375% 2030 Senior Notes, the 5.0% 2046 Senior Notes, and the 4.375% 2047 Senior Notes, contain customary events of default and covenants that, among other things and subject to certain exceptions, restrict us and certain of our subsidiaries' ability to (1) incur certain secured indebtedness, (2) engage in certain sale and leaseback transactions and (3) consolidate, merge or transfer all or substantially all of its assets.
As of June 30, 2020, we were in compliance with all of our long-term debt covenants.
Westlake Chemical Partners LP Credit Arrangements
Our subsidiary, Westlake Chemical Finance Corporation, is the lender party to a $600 million revolving credit facility with WLKP, originally entered into on April 29, 2015. On March 19, 2020, the revolving credit facility was amended to extend the maturity to March 2023 and add a phase-out provision for LIBOR, which is to be replaced by an alternate benchmark rate. Borrowings under the revolver bear interest, payable quarterly, at a variable rate of either (a) LIBOR plus 2.0% or (b) Alternate Base Rate plus 1.0%. WLKP 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 June 30, 2020, outstanding borrowings under the 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 Westlake Chemical OpCo LP ("OpCo"). The revolving credit facility is scheduled to mature in September 2023. As of June 30, 2020, 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 WLKP 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 WLKP and OpCo are eliminated upon consolidation.

FORWARD-LOOKING STATEMENTS
The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Certain of the statements contained in this report are forward-looking statements. All statements, other than statements of historical facts, included in this report that address activities, events or developments that we expect, project, believe or anticipate will or may occur in the future are forward-looking statements. Forward-looking statements can be identified by the use of words such as "believes," "intends," "may," "should," "could," "anticipates," "expected" or comparable terminology, or by discussions of strategies or trends. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot give any assurances that these expectations will prove to be correct. Forward-looking statements relate to matters such as:
future operating rates, margins, cash flows and demand for our products;
industry market outlook, including the price of crude oil;
widespread outbreak of an illness or any other communicable disease, or any other public health crisis, including the COVID-19 pandemic;
our plans to respond to the challenges presented by the COVID-19 pandemic, including planned reductions of costs, increases of operating efficiencies and lowering of our capital spending, as well as the timing and deferral of the planned turnaround at our Petro 2 ethylene unit;
production capacities;
currency devaluation;
our ability to borrow additional funds under our credit agreement;
our ability to meet our liquidity needs;
our ability to meet debt obligations under our debt instruments;
our intended quarterly dividends;
future capacity additions and expansions in the industries in which we compete;
results of acquisitions;
timing, funding and results of capital projects;
pension plan obligations, funding requirements and investment policies;
compliance with present and future environmental regulations and costs associated with environmentally related penalties, capital expenditures, remedial actions and proceedings, including any new laws, regulations or treaties that may come into force to limit or control carbon dioxide and other greenhouse gas emissions or to address other issues of climate change;
effects of pending legal proceedings; and
timing of and amount of capital expenditures.
We have based these statements on assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe were appropriate in the circumstances when the statements were made. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such statements. While it is not possible to identify all factors, we continue to face many risks and uncertainties. Among the factors that could cause actual future results to differ materially are the risks and uncertainties discussed under "Risk Factors" in the 2019 Form 10-K and those described from time to time in our other filings with the SEC including, but not limited to, the following:
general economic and business conditions;
the cyclical nature of the chemical and building products industries;
the availability, cost and volatility of raw materials and energy;
uncertainties associated with the United States, European and worldwide economies, including those due to political tensions and unrest in the Middle East and elsewhere;

34



uncertainties associated with pandemic infectious diseases, particularly COVID-19;
current and potential governmental regulatory actions in the United States and other countries;
industry production capacity and operating rates;
the supply/demand balance for our products;
competitive products and pricing pressures;
instability in the credit and financial markets;
access to capital markets;
terrorist acts;
operating interruptions (including leaks, explosions, fires, weather-related incidents, mechanical failure, unscheduled downtime, labor difficulties, transportation interruptions, spills and releases and other environmental risks);
changes in laws or regulations, including trade policies;
technological developments;
foreign currency exchange risks;
our ability to implement our business strategies; and
creditworthiness of our customers.
Many of such factors are beyond our ability to control or predict. Any of the factors, or a combination of these factors, could materially affect our future results of operations and the ultimate accuracy of the forward-looking statements. These forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially from those projected in the forward-looking statements. Management cautions against putting undue reliance on forward-looking statements or projecting any future results based on such statements or present or prior earnings levels. Every forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward-looking statements.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Commodity Price Risk
A substantial portion of our products and raw materials (such as ethane, natural gas and propane) 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 the olefins and vinyls 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 June 30, 2020, a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before income taxes by $12 million. Based on our open derivative positions at June 30, 2020 on ethylene (which are related to OpCo's third party sales), a hypothetical $0.10 decrease in the price of a pound of ethylene would have increased our income before income taxes by $4 million.
Interest Rate Risk
We are exposed to interest rate risk with respect to fixed and variable rate debt. At June 30, 2020, we had $3,790 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 $38 million. Also, at June 30, 2020, we had $11 million principal amount of variable rate debt outstanding, which 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 $11 million as of June 30, 2020 was 0.22%. A hypothetical 100 basis point increase in the average interest rate on our variable rate debt would not result in a material change in our annual interest expense.
LIBOR is used as a reference rate for borrowings under our revolving line of credit. LIBOR is set to be phased out at the end of 2021 and replaced by an alternate benchmark rate. We do not expect the impact of the LIBOR phase out to be material.

35



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 to reduce the volatility in stockholders' equity from changes in currency exchange rates associated with our net investments in foreign operations. The notional value of the net investment hedges was €150 million at June 30, 2020. The arrangement is scheduled to mature in 2026.
In July 2019, we completed the registered public offering of €700 million aggregate principal amount of the 1.625% Senior Notes due 2029. 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.
Item 4. 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 and our Executive Vice President and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 or 15d-15 under the Securities Exchange Act of 1934 as of the end of the period covered by this report. 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 with respect to (i) the accumulation and communication to our management, including our Chief Executive Officer and our Chief Financial Officer, of information required to be disclosed by us in the reports that we submit under the Exchange Act, and (ii) the recording, processing, summarizing and reporting of such information within the time periods specified in the SEC's rules and forms.
There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
Item 1. Legal Proceedings
The 2019 Form 10-K, filed on February 19, 2020, contained a description of various legal proceedings in which we are involved. See below and Note 13 to the unaudited consolidated financial statements within this Quarterly Report on Form 10-Q for description of certain of those proceedings, which information is incorporated by reference herein.
We 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. The defendant's joint motion to dismiss the direct purchaser lawsuits was denied, so those cases will proceed with discovery. At this time, we are not able to estimate the impact, if any, that these lawsuits could have on our consolidated financial statements either in the current period or in future periods.
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. Item 103 of the SEC's Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions, unless we reasonably believe such sanctions would not exceed $100,000.

In May 2013, an amendment to an existing consent order agreed to by the West Virginia Department of Environmental Protection and a predecessor of Axiall required that it, among other things, pay a penalty in the amount of $449,000 and continue certain corrective actions associated with discharges of hexachlorocyclohexane (commonly referred to as BHC) from the Natrium facility's effluent discharge outfalls. The penalty was paid and corrective actions required are on-going per a December 2018 agreement to extend the compliance date under the amended consent order. The amended consent order also imposes stipulated penalties for exceedances of the facility's interim effluent discharge limits, which penalties we believe may, in the aggregate, reach or exceed $100,000.
During September 2010, our vinyls facilities in Lake Charles and Plaquemine each received a Consolidated Compliance Order and Notice of Potential Penalty, alleging violations of various requirements of those facilities' air permits, based largely on self-reported permit deviations related to record-keeping violations. In May 2018, we reached an agreement in principal with the Louisiana Department of Environmental Quality to resolve these consolidated enforcement matters for a penalty of $162,500. The settlement agreement was issued for public comment, which concluded in March 2020. The settlement agreement was finalized and the penalty paid in June 2020, fully resolving this matter.
For several years, the Environmental Protection Agency (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 $100,000.
Region Six of the EPA has investigated and inspected our compliance with Risk Management Program requirements under the Clean Air Act at our Geismar facility. We entered into a consent agreement and final order with the EPA in February 2020 to resolve this matter. Under that consent agreement and final order, we paid a penalty in the amount of $132,000 in March 2020. In addition, the consent agreement and final order requires us to complete a supplemental environmental project with a cost of $116,200.
On November 24, 2014, we entered into an agreed order with the Kentucky Energy and Environmental Cabinet ("KEEC") regarding our Kentucky Pollutant Discharge Elimination System permit limits for hexachlorobenzene and mercury at our Calvert City, Kentucky facility. We and the KEEC entered into a new agreed order under which we will be subject to new interim discharge limits for hexachlorobenzene in addition to accompanying stipulated penalties for exceedances of those interim discharge limits, which penalties we believe may, in the aggregate, reach or exceed $100,000.
In August 2019, the Ohio Valley Environmental Coalition and the Sierra Club filed suit against the Company in the U.S. District Court for the Northern District of West Virginia alleging violations since May 2014 of discharge limits under a state-issued permit at our Natrium, West Virginia facility and seeking damages and injunctive relief. The Natrium facility's National Pollutant Discharge Elimination System ("NPDES") permit is subject to a consent order entered into with the West Virginia Department of Environmental Protection ("WVDEP"). Under the consent order and NPDES permit, the Natrium facility is subject to interim discharge limits for hexachlorocyclohexane (commonly referred to as "BHC") and mercury, any exceedances of which are subject to stipulated penalties outlined in the consent order. In March 2020, the court granted the Company's motion for summary judgment as to the plaintiffs' claims related to discharges of BHC, but denied summary judgment on plaintiffs' mercury claims. The Company disputes these claims and is actively pursuing all defenses in the matter. At this time, we are not able to estimate the impact, if any, that this lawsuit could have on our consolidated financial statements either in the current period or in future periods, but the resolution of these matters may require the payment of monetary sanctions in excess of $100,000.
We do not believe that the resolution of any or all of these matters will have a material adverse effect on our financial condition, results of operations or cash flows.

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 June 30, 2020, 6,776,913 shares of our common stock had been acquired at an aggregate purchase price of approximately $399 million under the 2014 Program. Transaction fees and commissions are not reported in the average price paid per share in the table above. Decisions regarding the amount and the timing of purchases under the 2014 Program will be influenced by our cash on hand, our cash flows from operations, general market conditions and other factors. The 2014 Program may be discontinued by our Board of Directors at any time.
