WESTLAKE CHEMICAL CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(in thousands 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 December 31, 2016 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, 2016 (the " 2016 Form 10-K"), filed with the SEC on February 22, 2017 . 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, 2016 .
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 September 30, 2017 , its results of operations for the three and nine months ended September 30, 2017 and 2016 and the changes in its cash position for the nine months ended September 30, 2017 and 2016 .
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, 2017 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.
Recent Accounting Pronouncements
Revenue from Contracts with Customers (ASU No. 2014-09)
In May 2014, the Financial Accounting Standards Board ("FASB") issued an accounting standards update on a comprehensive new revenue recognition standard that will supersede the existing revenue recognition guidance. The new accounting guidance creates a framework by which an entity will allocate the transaction price to separate performance obligations and recognize revenue when each performance obligation is satisfied. Under the new standard, entities will be required to use judgment and make estimates, including identifying performance obligations in a contract, estimating the amount of variable consideration to include in the transaction price, allocating the transaction price to each separate performance obligation and determining when an entity satisfies its performance obligations. The standard allows for either "full retrospective" adoption, meaning that the standard is applied to all of the periods presented with a cumulative catch-up as of the earliest period presented, or "modified retrospective" adoption, meaning the standard is applied only to the most current period presented in the financial statements with a cumulative catch-up as of the current period. In 2016, the FASB issued various additional authoritative guidance for the new revenue recognition standard. The accounting standard will be effective for reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that the new accounting standard will have on its consolidated financial position, results of operations and cash flows. The Company has completed a preliminary assessment including detailed review of a representative sample of contracts with customers. The Company does not believe that adoption of the new accounting standard will materially impact timing or amounts of revenue recognized for the majority of its sales. The Company intends to elect the modified retrospective method of adoption.

(in thousands of dollars, except share amounts and per share data)

Recognition and Measurement of Financial Assets and Financial Liabilities (ASU No. 2016-01)
In January 2016, the FASB issued an accounting standards update making certain changes principally to the current guidance for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. Among other things, the guidance (1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value, with changes in fair value recognized in net income; (2) provide entities with a policy election to record equity investments without readily determinable fair values at cost, less impairment, and subsequent adjustments for observable price changes (changes in the basis of these equity investments to be reported in net income); (3) requires an entity that has elected the fair value option for financial liabilities to recognize changes in fair value due to instrument-specific credit risk separately in other comprehensive income; (4) clarified current guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities; and (5) requires specific disclosure pertaining to financial assets and financial liabilities in the financial statements. The accounting standard will be effective for reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that the new accounting guidance will have on its consolidated financial position, results of operations and cash flows.
Leases (ASU No. 2016-02)
In February 2016, the FASB issued an accounting standards update on a new lease standard that will supersede the existing lease guidance. The standard requires a lessee to recognize assets and liabilities related to long-term leases that are classified as operating leases under current guidance on its balance sheet. An asset would be recognized related to the right to use the underlying asset and a liability would be recognized related to the obligation to make lease payments over the term of the lease. The standard also requires expanded disclosures related to leases. The accounting standard will be effective for reporting periods beginning after December 15, 2018. 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.
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 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. The accounting standard will be effective for reporting periods beginning after December 15, 2019 and is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Cash Flows (ASU No. 2016-15)
In August 2016, the FASB issued an accounting standards update providing new guidance on the classification of certain cash receipts and payments including debt extinguishment costs, debt prepayment costs, settlement of zero-coupon debt instruments, contingent consideration payments, proceeds from the settlement of insurance claims and life insurance policies and distributions received from equity method investees in the statement of cash flows. This update is required to be applied using the retrospective transition method to each period presented unless it is impracticable to be applied retrospectively. In such situation, this guidance is to be applied prospectively. The accounting standard will be effective for reporting periods beginning after December 15, 2017 and is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Cash Flows (ASU No. 2016-18)
In November 2016, the FASB issued an accounting standards update to clarify certain existing principles in Accounting Standards Codification ("ASC") 230, Cash flows, including providing additional guidance related to transfers between cash and restricted cash and how entities present, in their statement of cash flows, the cash receipts and cash payments that directly affect the restricted cash accounts. The accounting standard will be effective for reporting periods beginning after December 15, 2017. Upon adoption of the accounting standards update, the Company will retrospectively adjust its financial statements to reflect restricted cash in the beginning and ending cash and restricted cash balances within the statements of cash flows. Transfers between cash and restricted cash will be excluded from net changes in cash and cash equivalents within the statements of cash flows.

In January 2017, the FASB issued an accounting standards update to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in the ASC 606, Revenue from contracts with customers. The accounting standard will be effective for reporting periods beginning after December 15, 2017 and is not expected to 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 will be effective for reporting periods beginning after December 15, 2019 and is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (ASU No. 2017-05)
In February 2017, the FASB issued an accounting standards update to clarify the scope of guidance related to other income gains and losses from the derecognition of nonfinancial assets, and to add guidance for partial sales of nonfinancial assets. The new guidance clarifies that an in substance nonfinancial asset is an asset or group of assets for which substantially all of the fair value consists of nonfinancial assets and the group or subsidiary is not a business. The guidance also outlines that when an entity transfers its controlling interest in a nonfinancial asset, but retains a noncontrolling interest, it will measure the retained interest at fair value resulting in full gain or loss recognition upon sale of the controlling interest. The accounting standard will be effective for reporting periods beginning after December 15, 2017 and is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Compensation - Retirement Benefits (ASU No. 2017-07)
In March 2017, the FASB issued an accounting standards update to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance requires employers to disaggregate the service cost component from the other components of net periodic benefit cost and report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The amendments also allow only the service cost component to be eligible for capitalization when applicable. The accounting standard will be effective for reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that the new accounting guidance will have on its consolidated financial position, results of operations and cash flows.
Compensation - Stock Compensation (ASU No. 2017-09)
In May 2017, the FASB issued the accounting standards update to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation-Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require the application of modification accounting in Topic 718. Essentially, an entity will not have to account for the effects of a modification if: (1) the fair value of the modified award is the same immediately before and after the modification; (2) the vesting conditions of the modified award are the same immediately before and after the modification; and (3) the classification of the modified award as either an equity instrument or liability instrument is the same immediately before and after the modification. This update is to be applied prospectively to an award modified on or after the adoption date. The accounting standard will be effective for reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is in the process of evaluating the impact that the new accounting guidance will have on its consolidated financial position, results of operations and cash flows.

Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities (ASU No. 2017-12)
In August 2017, the FASB issued an accounting standards update to improve financial reporting of hedging relationships, to better portray the economic results of an entity's risk management activities in the financial statements and to simplify application of hedge accounting guidance. The accounting standard eliminates certain hedge effectiveness measurement and reporting requirements and expands the types of permissible hedging strategies. The accounting standard will be effective for reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted in any interim period after issuance, to be applied retrospectively to the beginning of the fiscal year. The Company is in the process of evaluating the impact that the new accounting guidance will have on its consolidated financial position, results of operations and cash flows.
Recently Adopted Accounting Standards
Investments - Equity Method and Joint Ventures (ASU No. 2016-07)
In March 2016, the FASB issued an accounting standards update providing new guidance for the accounting for equity method investments. The new guidance eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. In addition, the guidance requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The accounting standard became effective for reporting periods beginning after December 15, 2016. The Company adopted this accounting standard effective January 1, 2017 and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Stock Compensation (ASU No. 2016-09)
In March 2016, the FASB issued an accounting standards update to simplify several aspects of the accounting for share-based payment transactions, including income tax consequences, classifications of awards as either equity or liabilities and certain related classifications on the statement of cash flows. In addition, the new guidance permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards. Forfeitures can be estimated, as required prior to adoption of the accounting standards update, or recognized when they occur. The accounting standard became effective for reporting periods beginning after December 15, 2016. The Company adopted this accounting standard effective January 1, 2017 and elected to continue estimating forfeitures as required prior to adoption of the accounting standards update. The adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.
Amendments to the Consolidation Analysis (ASU No. 2016-17)
In October 2016, the FASB issued an accounting standards update making certain changes to the current consolidation guidance. The amendments affect reporting entities that are required to evaluate whether they should consolidate a variable interest entity in certain situations involving entities under common control. Specifically, the amendments change the evaluation of whether a reporting entity is the primary beneficiary of a variable interest entity by changing how a reporting entity that is a single decision maker of a variable interest entity treats indirect interests in the entity held through related parties that are under common control with the reporting entity. The amendments became effective for annual periods beginning after December 15, 2016. The Company adopted this accounting standard, to be applied prospectively, effective January 1, 2017, and the adoption did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

2. Acquisition
On August 31, 2016, the Company completed its acquisition of, and acquired all the remaining equity interest in, Axiall Corporation ("Axiall"), a Delaware corporation. Prior to the acquisition, the Company held 3.1 million shares in Axiall. Pursuant to the terms of the Agreement and Plan of Merger, dated as of June 10, 2016, by and among Westlake, Axiall and Lagoon Merger Sub, Inc., a Delaware corporation that is a wholly-owned subsidiary of Westlake ("Merger Sub"), the Company acquired all of the remaining issued and outstanding shares of common stock of Axiall for $33.00 per share in cash. Pursuant to the Merger Agreement, Merger Sub was merged with and into Axiall and Axiall survived the merger as a wholly-owned subsidiary of the Company (the "Merger"). The combined company is the third-largest global chlor-alkali producer and the third-largest global polyvinyl chloride ("PVC") producer. The Company's management believes that this strategic acquisition will enhance its strategy of integration and will further strengthen its role in the North American markets.
Axiall produces a highly integrated chain of chlor-alkali and derivative products, including chlorine, caustic soda, vinyl chloride monomer ("VCM"), PVC resin, PVC compounds and chlorinated derivative products. Axiall also manufactures and sells building products, including siding, trim, mouldings, pipe and pipe fittings.
Total consideration transferred for the Merger was $2,539,360 . The Merger was accounted for under the acquisition method of accounting. The assets acquired and liabilities assumed and the results of operations of the acquired business are included in the Company's Vinyls segment.
For the  nine months ended September 30, 2016 , the Company recognized  $90,550  of transaction and integration-related costs. This included acquisition-related costs of  $43,895  for advisory, consulting and professional fees and other expenses during the nine months ended September 30, 2016 . Transaction and integration-related costs also included $46,655  during the nine months ended September 30, 2016 related to the settlement of Axiall share-based awards, retention agreement costs and severance benefits provided to former Axiall employees in connection with the Merger.
The following table summarizes the consideration transferred and the estimated fair value of identified assets acquired and liabilities assumed at the date of acquisition. The allocation of the consideration transferred is based on management's estimates, judgments and assumptions. When determining the fair values of assets acquired, liabilities assumed and noncontrolling interests of the acquiree, management made significant estimates, judgments and assumptions. Management estimated that consideration paid exceeded the fair value of the net assets acquired. Therefore, goodwill of $942,096 was recorded. The goodwill recognized is primarily attributable to synergies related to the Company's vinyls integration strategy that are expected to arise from the Merger. All of the goodwill is assigned to the Company's Vinyls segment. As a portion of the goodwill arising from the Merger is attributable to foreign operations, there will be a continuing foreign currency impact to goodwill in the consolidated financial statements.

These amounts have not been eliminated for pro forma purposes because they do not relate to nonrecurring, transaction specific costs related to the Merger.
The pro forma amounts above have been calculated after applying the Company's accounting policies and adjusting the Axiall results to reflect (1) the increase to depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets had been applied from January 1, 2016; (2) the elimination of net sales and cost of sales between the Company and Axiall; (3) additional pension service costs; (4) amortization of debt premium and accretion of asset retirement obligations and environmental liabilities as part of the Company's adjustments to fair value; (5) incremental interest expense that would have been incurred assuming the financing arrangements entered by the Company and repayment of a portion of Axiall's outstanding debt had occurred on January 1, 2016; (6) the elimination of transaction-related costs; and (7) an adjustment to tax-effect the aforementioned pro forma adjustments using an estimated aggregate statutory income tax rate of the jurisdictions to which the above adjustments relate. The pro forma amounts do not include any potential synergies, cost savings or other expected benefits of the Merger, are presented for illustrative purposes only and are not necessarily indicative of results that would have been achieved if the Merger had occurred as of January 1, 2016 or of future operating performance.

6. Property, Plant and Equipment
As of September 30, 2017 , the Company had property, plant and equipment, net totaling $6,343,637 . The Company assesses these assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, including when negative conditions such as significant current or projected operating losses exist. Other factors considered by the Company when determining if an impairment assessment is necessary include, but are not limited to, significant changes or projected changes in supply and demand fundamentals (which would have a negative impact on operating rates or margins), new technological developments, new competitors with significant raw material or other cost advantages, adverse changes associated with the U.S. and world economies and uncertainties associated with governmental actions. Long-lived assets assessed for impairment are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.

12. Stock-Based Compensation
Under the Westlake Chemical Corporation 2013 Omnibus Incentive Plan (as amended and restated, the "2013 Plan"), all employees and non-employee directors of the Company, as well as certain individuals who have agreed to become the Company's employees, are eligible for awards. Shares of common stock may be issued as authorized in the 2013 Plan.

Total stock-based compensation expense related to the 2013 Plan was $5,972 and $1,502 for the three months ended September 30, 2017 and 2016 , respectively, and $16,740 and $6,588 for the nine months ended September 30, 2017 and 2016 , respectively.

Under the Merger Agreement, all outstanding Axiall restricted stock units were assumed by the Company and converted into restricted stock units in respect of the Company's common stock, with the same terms and conditions except that upon settlement the award holders will receive the greater of (1) the value of $33.00 per Axiall restricted stock unit that was converted into a restricted stock unit in respect of the Company's common stock and (2) the value of the Company's common stock. The awards are classified as liability awards for financial accounting purposes and are re-measured at each reporting date until they vest.
13. Derivative Instruments
Commodity Risk Management
The Company uses derivative instruments to reduce price volatility risk on commodities, primarily ethane and natural gas. The Company does not use derivative instruments to engage in speculative activities. The Company had no derivative instruments that were designated as fair value hedges during the three and nine months ended September 30, 2017 and 2016 .
The exposure on commodity derivatives used for price risk management includes the risk that the counterparty will not pay if the market declines below the established fixed price. In such case, the Company would lose the benefit of the derivative differential on the volume of the commodities covered. In any event, the Company would continue to receive the market price on the actual volume hedged. The Company also bears the risk that it could lose the benefit of market improvements over the fixed derivative price for the term and volume of the derivative instruments (as such improvements would accrue to the benefit of the counterparty). The Company had non-hedge designated feedstock forward contracts for approximately 138,600,000 gallons and 12,500,000 MMBtu as of September 30, 2017 and for approximately  257,000,000  gallons and  8,500,000  MMBtu as of December 31, 2016 .

14. 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.

The Level 2 measurements for the Company's commodity contracts are derived using forward curves supplied by industry-recognized and unrelated third-party services.
There were no transfers in or out of Levels 1 and 2 of the fair value hierarchy for the nine months ended September 30, 2017 and 2016 .
In addition to the financial assets and liabilities above, the Company has other 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 current 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, accounts payable and current term loan approximate their fair values due to the short maturities of these instruments. The carrying and fair values of the Company's long-term debt are summarized in the table below. The fair value of the Company's long-term debt instruments is determined using a market approach, based upon quotes from financial reporting services. 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.

15. Income Taxes
The effective income tax rate was 33.1% for the third quarter of 2017 . The effective income tax rate for the third quarter of 2017 was below the U.S. federal statutory rate of 35.0% primarily due to a higher domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, research and development credits and the foreign earnings rate differential, partially offset by state income taxes. The effective income tax rate, which was a benefit, was (10.3)% for three months ended September 30, 2016 . The effective income tax rate for the third quarter of 2016 was below the U.S. federal statutory rate of 35.0% primarily due to the benefit of state tax credits, the domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, the non-recognition of tax related to the gain recognized on previously held outstanding shares of common stock of Axiall, the benefit in prior years' and current-year tax credits for increased research and development expenditures and adjustments related to prior years' tax returns as filed and the foreign earnings rate differential, partially offset by state income taxes and nondeductible transaction costs related to the Merger.
The effective income tax rate was 30.8% for the nine months ended September 30, 2017 . The effective income tax rate for the nine months ended September 30, 2017 was below the U.S. federal statutory rate of 35.0% primarily due to certain discrete adjustments, a higher domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, research and development credits and the foreign earnings rate differential, partially offset by state income taxes. The effective income tax rate was 29.1% for the nine months ended September 30, 2016 . The effective income tax rate for the 2016 period was below the U.S. federal statutory rate of 35.0% primarily due to the benefit of state tax credits, the domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, the non-recognition of tax related to the gain recognized on previously held outstanding shares of common stock of Axiall, the benefit in prior years' and current-year tax credits for increased research and development expenditures and adjustments related to prior years' tax returns as filed and the foreign earnings rate differential, partially offset by state income taxes and nondeductible transaction costs related to the Merger.
The Company files income tax returns in the U.S. federal jurisdiction and in various states and foreign jurisdictions. During the second quarter of 2017, the Internal Revenue Service began an audit of the Company for the tax years 2012 to 2014.
16. 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 the periods. Diluted earnings per share include the effect of certain stock options.

18. 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 outcomes 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, specific outcomes with respect to such matters may be material to the Company's consolidated statements of operations in any particular period in which costs, if any, are recognized. 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.
Environmental. As of September 30, 2017 and December 31, 2016 , the Company had reserves for environmental contingencies totaling approximately $47,409 and $48,817 , 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.
From time to time the Company receives 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 the Company reasonably believes such sanctions would not exceed $100.
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 and continue certain corrective action associated with discharges of hexachlorocyclohexane (commonly referred to as BHC) from the Natrium, West Virginia facility's effluent discharge outfalls. The penalty was paid and corrective actions required are on-going per a December 2016 agreement to extend the compliance date under the amended consent order.
In May 2013 and September 2013, the Environmental Protection Agency (the "EPA") conducted inspections at the Company's Plaquemine, Louisiana facility pursuant to requirements of the federal Clean Air Act Section 112(r) Risk Management Program and Title V. As a result of the inspections, the EPA identified areas of concern and the Company subsequently engaged in negotiations to resolve alleged violations. A Consent Agreement and Final Order (“CAFO”) was filed in October 2016, pursuant to which the Company paid civil penalties in the amount of $167 .
The LDEQ has issued notices of violations ("NOVs") regarding the Company's olefins facilities in Lake Charles, Louisiana for various air and water compliance issues. The Company has reached an agreement with the LDEQ to settle certain of the NOVs along with other alleged violations not made the subject of any specific NOV in two separate settlement agreements, pursuant to which the Company paid $192 in civil penalties.
During September 2010, the Company's vinyls facilities in north 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. The Company has been negotiating a possible global settlement of these and several other matters with the LDEQ. The Company believes the resolution of these matters may require the payment of a monetary sanction in excess of $100 .
In April 2015, Axiall received a communication from the EPA related to, among other things, the EPA's investigation of the 2012 and 2013 fires that occurred at its VCM plant in Lake Charles. In late 2015, Axiall settled this matter with the EPA, with such settlement including on-going supplemental environmental projects and a penalty payment of $878 .

(in thousands of dollars, except share amounts and per share data)

For several years, the EPA has been conducting an enforcement initiative against petroleum refineries and petrochemical plants with respect to emissions from flares. On April 21, 2014, the Company received a Clean Air Act Section 114 Information Request from the EPA which sought information regarding flares at the Calvert City, Kentucky and certain Lake Charles facilities. The EPA has informed the Company 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 the Company to take corrective actions relating to the alleged noncompliance. The Company believes the resolution of these matters may require the payment of a monetary sanction in excess of $100 .
The Company does not believe that resolutions of any or all of these matters will have a material adverse effect on the Company's financial condition, results of operations or cash flows.
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  $40,000  to  $80,000 .
Commitments. In connection with the Merger, the Company became a party to a joint venture investment with Lotte Chemical USA Corporation to build an ethylene facility, LACC, LLC ("LACC"). The ethylene facility is located adjacent to the Company's vinyls facility in Lake Charles. Pursuant to the contribution and subscription agreement, the Company agreed to make a maximum capital commitment to LACC of up to $225,000 to fund the construction costs of the ethylene plant, which represents approximately 10.0% of the interests in LACC. The construction of the ethylene plant commenced in January 2016, with an anticipated start-up in 2019. As of September 30, 2017 , the Company had funded approximately $106,405 of the Company's portion of the construction costs of the ethylene plant.
19. 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.

20. Westlake Chemical Partners LP Offerings
In March 2014, we formed Westlake Chemical Partners LP ("WLKP") to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, WLKP completed its initial public offering (the "IPO") of 12,937,500 common units at a price of $24.00 per unit. Net proceeds to WLKP from the sale of the units was approximately $286,100 , net of underwriting discounts, structuring fees and estimated offering expenses of approximately $24,400 . At the consummation of the IPO, WLKP's assets consisted of a 10.6% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), as well as the general partner interest in OpCo. Immediately after the IPO, the Company retained an 89.4% limited partner interest in OpCo and a significant interest in WLKP. The initial public offering represented the sale of 47.8% of the common units in WLKP.
On April 29, 2015, WLKP purchased an additional 2.7% newly-issued limited partner interest in OpCo. On September 29, 2017, WLKP purchased an additional 5.0% newly-issued limited partner interest in OpCo.
On September 29, 2017, WLKP completed a secondary offering of 5,175,000 common units at a price of $22.00 per unit. Net proceeds to WLKP from the sale of the units was $110,739 , net of underwriting discounts, structuring fees and estimated offering expenses of approximately $3,111 . At September 30, 2017, WLKP had a 18.3% limited partner interest in OpCo, and the Company retained a 81.7% limited partner interest in OpCo and a significant interest in WLKP.
21. Subsequent Events
Subsequent events were evaluated through the date on which the consolidated financial statements were issued.
22. Guarantor Disclosures
The Company's payment obligations under the 3.60% senior notes due 2022 , the 3.60% 2026 Senior Notes, the 5.0% 2046 Senior Notes, 4.625% Westlake 2021 Senior Notes and the 4.875% Westlake 2023 Senior Notes are fully and unconditionally guaranteed by each of its current and future domestic subsidiaries that guarantee other debt of the Company or of another guarantor of those notes in excess of $5,000 (the "Guarantor Subsidiaries"). Each Guarantor Subsidiary is 100% owned by Westlake Chemical Corporation (the " 100% Owned Guarantor Subsidiaries"). In October 2016, the Company executed a Joinder Agreement with the Administrative Agent of the Credit Agreement, whereby certain subsidiaries of the Company were added as Guarantor Subsidiaries. These guarantees are the joint and several obligations of the Guarantor Subsidiaries. The following unaudited condensed consolidating financial information presents the financial condition, results of operations and cash flows of Westlake Chemical Corporation, the 100% owned Guarantor Subsidiaries, and the remaining subsidiaries that do not guarantee the 3.60% senior notes due 2022 , the 3.60% 2026 Senior Notes, the 5.0% 2046 Senior Notes, 4.625% Westlake 2021 Senior Notes and the 4.875% Westlake 2023 Senior Notes (the "Non-Guarantor Subsidiaries"), together with consolidating eliminations necessary to present the Company's results on a consolidated basis.
In August 2016, certain of the Company's subsidiary guarantors were released from their guarantees of the Company's 3.60% senior notes due 2022 in connection with the replacement of the Company's revolving credit facility. Westlake Chemical OpCo LP, which was previously separately presented as a less than 100% owned guarantor, and certain of the Company's other 100% owned subsidiaries that were previously presented as guarantors, are now reflected as Non-Guarantor Subsidiaries in the condensed consolidating guarantor financial information. Prior periods were retrospectively adjusted to conform to the current presentation of Guarantor Subsidiaries and Non-Guarantor Subsidiaries.

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") 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, 2016 (the " 2016 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 petrochemicals, polymers and building products. Our two principal operating segments are Olefins and Vinyls. We use a majority of our internally-produced basic chemicals to produce higher value-added chemicals and building products.
Since 2009 and continuing through the third quarter of 2017 , a cost advantage for ethane-based ethylene producers over naphtha-based ethylene producers has allowed a strong export market for polyethylene and ethylene derivatives and higher margins for North American chemical producers, including Westlake. However, the falling crude oil prices in recent years have resulted in reduced prices and margins. Continued strong global demand for polyethylene has resulted in improved operating margins and cash flows for our Olefins segment in recent years. 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, beginning in the third quarter of 2014 and continuing through the third quarter of 2017 . Looking forward, new ethylene and polyethylene capacity additions in North America, Asia and the Middle East, and a number of new capacities announced in recent years, may lead to periods of over-supply and lower profitability. As a result, our Olefins segment operating margins may be negatively impacted.
Since the 2008 housing market collapse, continued slow recovery in the U.S. construction markets and budgetary constraints in municipal spending have contributed to lower North American demand for our vinyls products, which have negatively impacted our Vinyls segment operating rates and margins. However, 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. In addition, our July 2014 acquisition of Vinnolit Holdings GmbH and its subsidiary companies ("Vinnolit"), an integrated global leader in specialty PVC resins, has contributed to improved operating margins and cash flows for our Vinyls segment. 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. Announced capacity is now complete and increasing demand driven by the improving economic growth and U.S. producers' competitive export position is expected to result in improved operating rates and caustic soda pricing. On August 31, 2016, we completed the acquisition of Axiall Corporation ("Axiall") for $33.00 per share in an all-cash transaction (the "Merger"). The combined company is the third-largest global chlor-alkali producer and the third-largest PVC producer in the world. Westlake is the second-largest purchaser of ethylene in the U.S. and lower prices could positively impact our Vinyls segment.
The economic environment in the U. S. and globally appears to be improving. However, depending on the performance of the global economy in the remainder of 2017 and beyond, our financial condition, results of operations or cash flows could be negatively impacted.
Non-GAAP Financial Measures
The body of accounting principles generally accepted in the United States is commonly referred to as "U.S. 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, but excludes or includes amounts that would not be so adjusted in the most comparable GAAP measures. In this report, we disclose non-GAAP financial measures, primarily earnings before interest, taxes, depreciation and amortization ("EBITDA"). EBITDA is calculated 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 flow.

39

Table of Contents


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 earnings or of cash flow 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.
Recent Developments
On September 29, 2017, Westlake Chemical Partners, LP ("WLKP") completed a secondary offering of 5,175,000 common units at a price of $22.00 per unit and purchased an additional 5.0% newly-issued limited partner interest in Westlake Chemical OpCo LP ("OpCo") for approximately $229.2 million resulting in an aggregate 18.3% limited partner interest in OpCo effective July 1, 2017. Net proceeds to WLKP from the sale of the units was $110.7 million, net of underwriting discounts, structuring fees and estimated offering expenses of approximately $3.1 million. WLKP used the proceeds from the offering and the existing revolving credit facility with Westlake Chemical Finance Corporation, our subsidiary, to fund the purchase of the additional 5.0% interest in OpCo.
During September 2017, we directed the Louisiana Local Government Authority Environmental Facilities and Community Development Authority (the “Authority”) to optionally redeem in full $250.0 million aggregate principal amount of the 2007 Series revenue bonds (the “GO Zone Bonds”) on November 1, 2017 at a redemption price of par, plus accrued and unpaid interest, if any, to the redemption date. The GO Zone Bonds were issued by the Authority in December 2007 under the Gulf Opportunity Zone Act of 2005 (GO Zone Act) for the benefit of the Company and were subject to optional redemption by the Authority at any time on or after November 1, 2017 for 100.0% of the principal plus accrued unpaid interest, if any. In connection with the redemption of the Go Zone Bonds, the Authority is required to cause the GO Zone Bonds trustee to surrender the 6 ¾% tax exempt senior notes due November 2032 of $250.0 million, to the Senior Notes trustee for cancellation. We used cash on hand to fund the redemption of the GO Zone Bonds.
On August 30, 2017, following WLKP's cash distribution for the second quarter of 2017, the requirement under WLKP's partnership agreement for the conversion of all subordinated units was satisfied. As a result, effective August 30, 2017, the 12,686,115 subordinated units owned by us were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash.
On August 1, 2017, the Company, WLKP and OpCo executed an Investment Management Agreement (the "Investment Management Agreement") that authorized Westlake to invest the Partnership's and OpCo's excess cash.
On August 1, 2017, our wholly owned subsidiary, Westlake Chemical Finance Corporation, entered into an amendment to the revolving credit facility with WLKP, resulting in the extension of the credit facility's maturity date from April 29, 2018 to April 29, 2021.

Summary
For the quarter ended September 30, 2017 , net income attributable to Westlake Chemical Corporation was $210.8 million , or $1.61 per diluted share, on net sales of $2,108.9 million . This represents an increase in net income attributable to Westlake Chemical Corporation of $145.1 million , or $1.10 per diluted share, compared to the third quarter of 2016 net income attributable to Westlake Chemical Corporation of $65.7 million , or $0.51 per diluted share, on net sales of $1,279.0 million . Net income for the third quarter of 2017 increased versus the prior-year period primarily due to (1) earnings contributed by Axiall, which was acquired on August 31, 2016; (2) lower transaction and integration-related costs associated with the acquisition; and (3) higher sales prices for major products resulting in improved margins. These increases, as compared to the third quarter of 2016 , were partially offset by (1) higher interest expense due to the increased debt balance as a result of the Axiall acquisition; (2) a third quarter 2016 realized gain of $49.1 million from the previously held common stock of Axiall; and (3) a higher effective tax rate. Net sales for the third quarter of 2017 increase d by $829.9 million compared to net sales for the third quarter of 2016 , mainly due to higher sales contributed by Axiall and higher sales prices for our major products. Income from operations was $365.7 million for the third quarter of 2017 as compared to $46.6 million for the third quarter of 2016 . The increase in income from operations for the third quarter of 2017 was mainly a result of earnings contributed by Axiall, lower transaction and integration-related costs and higher sales prices as compared to the third quarter of 2016 . Transaction and integration-related costs in the third quarter of 2017 were $6.7 million , or $0.03 per diluted share.
For the nine months ended September 30, 2017 , net income attributable to Westlake Chemical Corporation was $501.8 million , or $3.85 per diluted share, on net sales of $6,030.7 million . This represents an increase in net income attributable to Westlake Chemical Corporation of $201.9 million , or $1.56 per diluted share, compared to the nine months ended September 30, 2016 net income attributable to Westlake Chemical Corporation of $299.9 million , or $2.29 per diluted share, on net sales of $3,340.3 million . Net income for the nine months ended September 30, 2017 increased versus the prior-year period primarily due to (1) earnings contributed by Axiall; (2) higher sales prices for our major products, resulting in improved margins; and (3) lower transaction and integration-related costs associated with the integration of Axiall. These increases versus the prior-year period were partially offset by higher interest expense due to the increased debt balance and the realized gain in the nine months ended September 30, 2016 of $49.1 million from the previously held common stock of Axiall. Net sales for the nine months ended September 30, 2017 increase d by $2,690.4 million compared to net sales for the nine months ended September 30, 2016 , mainly due to higher sales contributed by Axiall, which was acquired on August 31, 2016, and higher sales prices for our major products. Income from operations was $868.2 million for the nine months ended September 30, 2017 as compared to $428.8 million for the nine months ended September 30, 2016 . The increase in income from operations was mainly a result of earnings contributed by Axiall, higher sales prices for our major products and lower transaction and integration-related costs.

Transaction and Integration-related Costs . The transactions and integration-related costs were $6.7 million in the third quarter of 2017 as compared to $82.8 million in the third quarter of 2016 . Transaction and integration-related costs were lower by $76.1 million in the third quarter of 2017 as compared to the third quarter of 2016 predominantly because significant transaction and integration-related costs were incurred at the time of the Merger in the third quarter of 2016 . The transaction and integration costs for the third quarter of 2017 primarily consisted of severance benefits provided to former Axiall employees in conjunction with the Merger and integration costs and consulting fees related to the Merger. The transaction and integration-related costs for the third quarter of 2016 primarily consisted of severance benefits provided to former Axiall executives in conjunction with the Merger, including the conversion of Axiall restricted stock units into our restricted stock units, transitional service expenses for certain former Axiall employees, retention agreement costs and consulting and professional fees related to the Merger.
Interest Expense . Interest expense increase d by $15.6 million to $40.0 million in the third quarter of 2017 from $24.4 million in the third quarter of 2016 primarily as a result of higher average debt outstanding for the period as well as decreased capitalized interest on major capital projects in the third quarter of 2017 as compared to the third quarter of 2016 . The debt balance increased in August 2016 to finance the Merger. See "Liquidity and Capital Resources—Debt" below for further discussion on our indebtedness.
Other Income (Expense), Net . Other income, net decrease d by $39.2 million to income of $2.1 million in the third quarter of 2017 from income of $41.3 million in the third quarter of 2016 . The decrease was primarily attributable to the realized gain in the third quarter of 2016 of $49.1 million from the previously held common stock of Axiall.
Income Taxes. The effective income tax rate was 33.1% for the third quarter of 2017 . The effective income tax rate for the third quarter of 2017 was below the U.S. federal statutory rate of 35.0% primarily due to a higher domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, research and development credits and the foreign earnings rate differential, partially offset by state income taxes. The effective tax rate, which was a benefit, was (10.3)% for the three months ended September 30, 2016 . The effective income tax rate for the third quarter of 2016 was below the U.S. federal statutory rate of 35.0% primarily due to the benefit of state tax credits, the domestic manufacturing deduction, depletion deductions, income attributable to noncontrolling interests, the non-recognition of tax related to the gain recognized on previously held outstanding shares of common stock of Axiall, the benefit in prior years' and current-year tax credits for increased research and development expenditures, adjustments related to prior years' tax returns as filed and the foreign earnings rate differential, partially offset by state income taxes and nondeductible transaction costs related to the Merger.
Olefins Segment
Net Sales . Net sales for the Olefins segment increase d by $4.8 million , or 1.0% , to $502.2 million in the third quarter of 2017 from $497.4 million in the third quarter of 2016 , primarily due to higher sales prices. Average sales volumes for the Olefins segment decrease d by 0.8% in the third quarter of 2017 as compared to the third quarter of 2016 . Average sales prices for the Olefins segment increase d by 1.8% in the third quarter of 2017 as compared to the third quarter of 2016 .
Income from Operations . Income from operations for the Olefins segment increase d by $46.9 million to $165.4 million in the third quarter of 2017 from $118.5 million in the third quarter of 2016 . This increase was mainly attributable to higher sales prices and higher overall operating rates. These increases were partially offset by higher feedstock and energy costs. Trading activity in the third quarter of 2017 resulted in a gain of $6.8 million as compared to a loss of $7.8 million in the third quarter of 2016 .
Vinyls Segment
Net Sales . Net sales for the Vinyls segment increase d by $824.9 million , or 105.5% , to $1,606.6 million in the third quarter of 2017 from $781.7 million in the third quarter of 2016 . This increase was mainly attributable to higher sales contributed by Axiall and higher sales prices for our major products. Net sales for the three months ended September 30, 2017 were higher as compared to the prior-year period primarily because a full three months of Axiall's operations were included as compared to only one month of Axiall's operations included in the prior-year period. Average sales prices for the Vinyls segment increase d by 18.7% in the third quarter of 2017 as compared to the third quarter of 2016 . Average sales volumes for the Vinyls segment increase d by 86.8% in the third quarter of 2017 as compared to the third quarter of 2016 , primarily attributable to sales contributed by Axiall, as compared to the prior-year period.

The net sales for the nine months ended September 30, 2017 was higher as compared to the prior-year period primarily because nine months of Axiall's operations were included in the current period as compared to one month of Axiall operations included in the prior-year period. Average sales prices for the Vinyls segment increase d by 17.8% in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 . Average sales volumes for the Vinyls segment increase d by 116.7% in the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016 , primarily attributable to sales contributed by Axiall, as compared to the prior-year period.
Income from Operations. Income from operations for the Vinyls segment increase d by $294.7 million to $431.3 million in the nine months ended September 30, 2017 from $136.6 million in the nine months ended September 30, 2016 . This increase was mainly attributable to earnings contributed by Axiall and higher sales prices and volumes for our major products. These increases were partially offset by unabsorbed fixed manufacturing costs and other costs associated with the planned turnaround and expansion at the Calvert City facility and other planned and unplanned turnarounds as well as higher energy prices during the nine months ended September 30, 2017 , as compared to the prior-year period.
CASH FLOW DISCUSSION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 2017 AND 2016
Cash Flows
Operating Activities
Operating activities provide d cash of $962.7 million in the first nine months of 2017 compared to cash provide d by operating activities of $544.2 million in the first nine months of 2016 . The $418.5 million increase in cash flows from operating activities was mainly due to an increase in income from operations and lower turnaround related expenditures during the nine months ended September 30, 2017 as compared to the first nine months of 2016 , partially offset by an increase in working capital requirements. The increase in net income from operations for the first nine months of 2017 was mainly as a result of higher sales prices and volumes, resulting in a higher margin, and earnings contributed by Axiall, which was acquired on August 31, 2016. Changes in components of working capital, which we define for purposes of this cash flow discussion as accounts receivable, net, inventories, prepaid expenses and other current assets, less accounts payable and accrued liabilities, use d cash of $26.2 million in the first nine months of 2017 , compared to $10.5 million of cash provide d in the first nine months of 2016 , an unfavorable change of $36.7 million . The change was mainly driven by an unfavorable change in accounts receivable, partially offset by favorable changes in inventory, prepaid and other current assets and accounts payable.

Investing Activities
Net cash use d for investing activities during the first nine months of 2017 was $459.4 million as compared to net cash use d for investing activities of $2,389.1 million in the first nine months of 2016 . In the first nine months of 2016 we used $2,437.8 million, net of cash acquired, for the acquisition of Axiall. Capital expenditures were $414.3 million in the first nine months of 2017 compared to $467.3 million in the first nine months of 2016 . Capital expenditures in the first nine months of 2017 were primarily incurred on the upgrade and expansion of OpCo's Calvert City ethylene plant at our Calvert City site. Capital expenditures in the first nine months of 2016 were primarily incurred on the upgrade and expansion of OpCo's Petro 1 ethylene unit at our Lake Charles site. The remaining capital expenditures in the first nine months of 2017 and 2016 primarily related to projects to improve production capacity or reduce costs, maintenance and safety projects and environmental projects at our various facilities. In addition, we spent $47.0 million in the nine months of 2017 related to our contribution to Lotte Chemical USA Corporation to fund the construction costs of the ethylene plant. Please see "Liquidity and Capital Resources—Liquidity and Financing Arrangements" below for further discussion. Investing activities in the first nine months of 2016 included purchases of securities totaling $138.4 million . We also received aggregate proceeds of $662.9 million from the sales and maturities of our investments in the first nine months of 2016 .
Financing Activities
Net cash use d for financing activities during the first nine months of 2017 was $306.4 million as compared to net cash provide d by financing activities of $1,560.5 million in the first nine months of 2016 . We used $150.0 million and $550.0 million , respectively, for the full repayment of our term loan and the partial repayment of the Credit Agreement in the first nine months of 2017 . These uses were partially offset by a drawdown under the Credit Agreement of $225.0 million in the first nine months of 2017 and net proceeds of $110.7 million from the issuance of WLKP common units as a result of its secondary offering in September 2017. During the first nine months of 2017, the restriction on $154.0 million of cash was also removed as a result of the repayment of our term loan. The remaining activities during the first nine months of 2017 were primarily related to the $76.5 million payment of cash dividends, the $20.8 million payment of cash distributions to noncontrolling interests and the $0.4 million payment of debt issuance costs. In addition, we repaid $6.7 million of Huasu's short-term notes payable to banks in connection with the payment of suppliers through letters of credit, partially offset by $5.9 million of proceeds from the issuance of such notes payable. The financing activities during the first nine months of 2016 were mainly related to the net proceeds from the issuance of our senior notes and the proceeds from our term loan of $1,428.5 in the aggregate and the drawdown under the Credit Agreement of $600.0 million, partially offset by the $125.0 million partial repayment of the Credit Agreement in the first nine months of 2016. The remaining activity during the first nine months of 2016 was primarily related to the $71.9 million payment of cash dividends, the $12.3 million payment of cash distributions to noncontrolling interests, the $35.2 million payment of debt issuance costs and the $67.4 million of cash used for repurchases of shares of our common stock. In addition, we repaid $10.6 million of Huasu's short-term notes payable to banks in connection with the payment of suppliers through letters of credit, partially offset by $5.6 million of proceeds from the issuance of such notes payable in the first nine months of 2016.
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 $250.0 million share repurchase program (the "2014 Program"). In November 2015, our Board of Directors approved the expansion of the 2014 Program by an additional $150.0 million. As of September 30, 2017 , we had repurchased 4,193,598 shares of our common stock for an aggregate purchase price of approximately $228.7 million under the 2014 Program. Purchases under the 2014 Program may be made either through the open market or in privately negotiated transactions. Decisions regarding the amount and the timing of purchases under the 2014 Program will be influenced by our cash on hand, our cash flow from operations, general market conditions and other factors. The 2014 Program may be discontinued by our Board of Directors at any time.
In connection with the Merger, we became party to a joint venture investment with Lotte Chemical USA Corporation to build an ethylene facility, LACC, LLC ("LACC"). The ethylene facility is located adjacent to our vinyls facility in Lake Charles. Pursuant to the contribution and subscription agreement, we agreed to make a maximum capital commitment to LACC of up to $225.0 million to fund the construction costs of the ethylene plant, which represents approximately 10.0% of the interests in LACC. The construction of the ethylene plant commenced in January 2016, with an anticipated start-up in 2019. As of September 30, 2017 , we had funded approximately $106.4 million of our portion of the construction costs of the ethylene plant.

We believe that our sources of liquidity as described above will be adequate to fund our normal operations and ongoing capital expenditures. Funding of any potential large expansions or any 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 September 30, 2017 , our cash and cash equivalents totaled $678.2 million . In addition, we have the Credit Agreement available to supplement cash if needed, as described under "Debt" below.
Debt
As of September 30, 2017 , our indebtedness, including current maturities, totaled $3.3 billion , consisting of $100.0 million of 6 ½% senior notes due 2029, $250.0 million of 6 ¾% senior notes due 2032, $89.0 million of 6 ½% senior notes due 2035 (the "6 ½% 2035 GO Zone Senior Notes"), $65.0 million of 6 ½% senior notes due 2035 (the "6 ½% 2035 IKE Zone Senior Notes") (collectively, the "Senior Notes"), $624.8 million aggregate principal amount of 4.625% senior notes due 2021 (the "4.625% 2021 Senior Notes"), $63.2 million aggregate principal amount of the 4.625% senior notes due 2021 (the " 4.625% Subsidiary 2021 Senior Notes "), $250.0 million principal amount of 3.60% senior notes due 2022 (the "3.6% senior notes due 2022"), $433.8 million aggregate principal amount of 4.875% senior notes due 2023 (the "4.875% 2023 Senior Notes"), $16.2 million aggregate principal amount of the 4.875% senior notes due 2023 (the " 4.875% Subsidiary 2023 Senior Notes "), $750.0 million aggregate principal amount of 3.60% senior notes due 2026 (the " 3.60% 2026 Senior Notes "), $700.0 million aggregate principal amount of 5.0% senior notes due 2046 (the " 5.0% 2046 Senior Notes ") and a $10.9 million loan from the proceeds of tax-exempt waste disposal revenue bonds (supported by an $11.3 million letter of credit), plus unamortized premium net of unamortized discount and debt issuance costs of $3.5 million . The 6 ½% senior notes due 2029, the 6 ¾% senior notes due 2032, the 6 ½% 2035 GO Zone Senior Notes and the 6 ½% 2035 IKE Zone Senior Notes evidence and secure our obligations to the Louisiana Local Government Environmental Facility and Development Authority (the "Authority"), a political subdivision of the State of Louisiana, under four loan agreements relating to the issuance of $100.0 million, $250.0 million, $89.0 million and $65.0 million aggregate principal amount of the Authority's tax-exempt revenue bonds, respectively. As of September 30, 2017 , debt outstanding under the tax-exempt waste disposal revenue bonds bore interest at a variable rate. As of September 30, 2017 , we were in compliance with all of the covenants with respect to the Senior Notes, the 4,625% 2021 Senior Notes, the 4.625% Subsidiary 2021 Senior Notes , the 3.60% senior notes due 2022, the 4.875% 2023 Senior Notes, the 4.875% Subsidiary 2023 Senior Notes , the 3.60% 2026 Senior Notes , the 5.0% 2046 Senior Notes , the Credit Agreement and our waste disposal revenue bonds.
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 flow from operations, available cash and available borrowings under the Credit Agreement will be adequate to meet our normal operating needs for the foreseeable future.
Term Loan
On August 10, 2016, our indirect subsidiary, Westlake International Holdings II C.V., a limited partnership organized under the laws of the Netherlands (the "CV Borrower"), entered into a credit agreement with Bank of America, N.A., as agent and lender, providing the CV Borrower with a $150.0 million term loan facility. The term loan facility had a maturity date of March 31, 2017. The term loan was fully repaid in January 2017. The loans thereunder bore interest at a floating interest rate equal to LIBOR plus 2.0% per annum, payable in arrears on the last day of each three-month period following the date of funding and at maturity.

Credit Agreement
On August 23, 2016, we and certain of our subsidiaries entered into an unsecured revolving credit facility (the "Credit Agreement"), by and among us, the other borrowers and guarantors referred to therein, the lenders from time to time party thereto (collectively, the "Lenders"), the issuing banks party thereto and JPMorgan Chase Bank, National Association, as Administrative Agent. Under the Credit Agreement, the Lenders have committed to provide an unsecured five -year revolving credit facility in an aggregate principal amount of up to $1.0 billion . The Credit Agreement replaced our $400.0 million senior secured third amended and restated credit facility, dated as of July 17, 2014 (the "Prior ABL Credit Agreement"), by and among us, the financial institutions party thereto, as lenders, Bank of America, N.A., as agent, and us and certain of our subsidiaries, as borrowers. The Credit Agreement includes a $150.0 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 $50.0 million commitment for swing-line loans to be provided on a same-day basis. We may also increase the size of the facility, in increments of at least $25.0 million , up to a maximum of $500.0 million , subject to certain conditions and if certain Lenders agree to commit to such an increase. On October 14, 2016, certain domestic subsidiaries of Axiall and Lagoon LLC were added as subsidiary guarantors to the Credit Agreement.
At September 30, 2017 , we had no borrowings outstanding under the Credit Agreement. Borrowings under the Credit Agreement will bear interest, at our option, at either (a) LIBOR plus a spread ranging from 1.0% to 1.75% that will vary depending on our credit rating or (b) Alternate Base Rate plus a spread ranging from 0.0% to 0.75% that will vary depending on our credit rating. The Credit Agreement also requires an undrawn commitment fee ranging from 0.10% to 0.25% that will vary depending on our credit rating. The Credit Agreement matures on August 23, 2021. As of September 30, 2017 , we had outstanding letters of credit totaling $45.4 million and borrowing availability of $954.6 million under the Credit Agreement.
Our obligations under the Credit Agreement are guaranteed by our current and future material domestic subsidiaries, subject to customary exceptions. The Credit Agreement contains customary affirmative and negative covenants, including a quarterly total leverage ratio financial maintenance covenant. The Credit Agreement also contains customary events of default and if and for so long as an event of default has occurred and is continuing, any 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. As of September 30, 2017 , we were in compliance with the total leverage ratio financial maintenance covenant.
GO Zone and IKE Zone Bonds
As of September 30, 2017 , we had drawn all the proceeds from the issuance of the 6 ½% senior notes due 2029, 6 ¾% senior notes due 2032, 6 ½% 2035 GO Zone Senior Notes and 6 ½% 2035 IKE Zone Senior Notes. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt" in the 2016 Form 10-K and below for more information on the 6 ½% senior notes due 2029, the 6 ¾% senior notes due 2032, the 6 ½% 2035 GO Zone Senior Notes and the 6 ½% 2035 IKE Zone Senior Notes. All domestic restricted subsidiaries that guarantee other debt of ours or of another guarantor of the Senior Notes in excess of $5.0 million are guarantors of these notes.
The $250.0 million of 6 ¾% senior notes due November 1, 2032 under the GO Zone Act was issued by the Authority in December 2007. The bonds were subject to optional redemption by the Authority upon the direction of the Company at any time on or after November 1, 2017 for 100.0% of the principal plus accrued interest. During September 2017, we directed the Authority to optionally redeem in full $250.0 million 6 ¾% senior notes on November 1, 2017 at a redemption price of par, plus accrued and unpaid interest, if any, to the redemption date. The Authority is required to cause the GO Zone Bonds trustee to surrender the 6 ¾% senior notes due November 2032 of $250.0 million, to the Senior Notes trustee for cancellation. We used cash on hand to fund the redemption of the GO Zone Bonds.

The indentures governing the Senior Notes contain customary covenants and events of default. Accordingly, these agreements generally impose significant operating and financial restrictions on us. These restrictions, among other things, provide limitations on incurrence of additional indebtedness, the payment of dividends, certain investments and acquisitions and sales of assets. However, the effectiveness of certain of these restrictions is currently suspended because the Senior Notes are currently rated investment grade by at least two nationally recognized credit rating agencies. The most significant of these provisions, if it were currently effective, would restrict us from incurring additional debt, except specified permitted debt (including borrowings under our credit facility), when our fixed charge coverage ratio is below 2.0:1. These limitations are subject to a number of important qualifications and exceptions, including, without limitation, an exception for the payment of our regular quarterly dividend of up to $0.10 per share. If the restrictions were currently effective, distributions in excess of $100.0 million would not be allowed unless, after giving pro forma effect to the distribution, our fixed charge coverage ratio is at least 2.0:1 and such payment, together with the aggregate amount of all other distributions after January 13, 2006, is less than the sum of 50.0% of our consolidated net income for the period from October 1, 2003 to the end of the most recent quarter for which consolidated financial statements have been filed, plus 100.0% of net cash proceeds received after October 1, 2003 as a contribution to our common equity capital or from the issuance or sale of certain securities, plus several other adjustments.
3.60% Senior Notes due 2022
The 3.60% senior notes due 2022 are unsecured and were issued with an original issue discount of $1.2 million. There is no sinking fund and no scheduled amortization of the 3.60% senior notes due 2022 prior to maturity. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt" in the 2016 Form 10-K for more information on the 3.60% senior notes due 2022. All of our domestic subsidiaries that guarantee other indebtedness of ours or of another guarantor of the 3.60% senior notes due 2022 in excess of $5.0 million are guarantors of the 3.60% senior notes due 2022.
The indenture governing the 3.60% senior notes due 2022 contains customary events of default and covenants that will restrict our and certain of our 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 our or their assets.
3.60% Senior Notes due 2026 and 5.0% Senior Notes due 2046
In August 2016, we issued $750.0 million aggregate principal amount of the 3.60% 2026 Senior Notes and $700.0 million aggregate principal amount of the 5.0% 2046 Senior Notes . In connection with the private offering and issuance of the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes , we entered into a registration rights agreement pursuant to which, among other things, we agreed to file with the SEC a registration statement relating to an offer to exchange the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes for the 2026 and 2046 Exchange Notes containing terms substantially identical to the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes (except that the transfer restrictions on the 2026 and 2046 Exchange Notes will be modified or eliminated and there will be no registration rights). On March 27, 2017, we 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 notes have been registered under the Securities Act. The exchange offers expired on April 24, 2017, and approximately 99.97% of the 3.60% 2026 Senior Notes and 100.00% of the 5.0% 2046 Senior Notes were exchanged. The 3.60% 2026 Senior Notes that were not exchanged pursuant to 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 United States 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.
All of our domestic subsidiaries that guarantee other indebtedness of ours or of another guarantor of the 3.60% 2026 Senior Notes or the 5.0% 2046 Senior Notes in excess of $40.0 million are guarantors of the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes . The indenture governing the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes contains customary events of default and covenants that will restrict our and certain of our 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 our or their assets. References to the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes in this paragraph refer to the 3.60% 2026 Senior Notes and the 5.0% 2046 Senior Notes that were exchanged in the exchange offers described in the preceding paragraph as well as the 3.60% 2026 Senior Notes that were not exchanged in such exchange offers.

In connection with the private offering and issuance of the 4.625% 2021 Senior Notes and the 4.875% Senior Notes, we entered into a registration rights agreement pursuant to which, among other things, we agreed to file with the SEC a registration statement relating to an offer to exchange the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes for new SEC registered notes (the "2021 and 2023 Exchange Notes") containing terms substantially identical to the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes except that the transfer restrictions on the 2021 and 2023 Exchange Notes will be modified or eliminated and there will be no registration rights). On March 27, 2017, we commenced registered exchange offers to exchange the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes for new notes that are identical in all material respects to the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes, except that the offer and issuance of the new notes have been registered under the Securities Act. The exchange offers expired on April 24, 2017, and 100.0% of the 4.625% 2021 Senior Notes and 100.0% of the 4.875% 2023 Senior Notes were exchanged.
All of our domestic subsidiaries that guarantee other indebtedness of ours or of another guarantor of the 4.625% 2021 Senior Notes or the 4.875% 2023 Senior Notes in excess of $40.0 million are guarantors of the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes. The indenture governing the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes contains customary events of default and covenants that will restrict our and certain of our 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 our or their assets. References to the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes in this paragraph refer to the 4.625% 2021 Senior Notes and the 4.875% 2023 Senior Notes that were exchanged in the exchange offers described in the preceding paragraph.
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 $10.9 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.
Westlake Chemical Partners LP Credit Arrangements
Our subsidiary, Westlake Chemical Finance Corporation, is the lender party to a $300.0 million revolving credit facility with Westlake Chemical Partners LP ("WLKP"). On August 1, 2017, the revolving credit facility was amended to extend the maturity from 2018 to 2021. Borrowings under the revolver bear interest at LIBOR plus a spread ranging from 2.0% to 3.0% (depending on WLKP's consolidated leverage ratio), payable quarterly. 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 September 30, 2017 , outstanding borrowings under the credit facility totaled $253.5 million and bore interest at the LIBOR rate plus 2.0% .
Our subsidiary, Westlake Development Corporation, is the lender party to a $600.0 million revolving credit facility with OpCo. The revolving credit facility matures in 2019. As of September 30, 2017 , outstanding borrowings under the credit facility totaled $223.6 million and bore interest at the LIBOR rate plus 3.0%, 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.
Off-Balance Sheet Arrangements
None.

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 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 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 at September 30, 2017 , a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before taxes by $6.9 million and a hypothetical $0.10 increase in the price of a gallon of propane would have increased our income before taxes by $3.8 million. Additional information concerning derivative commodity instruments appears in Notes 13 and 14 to the unaudited consolidated financial statements within this Quarterly Report on Form 10-Q.
Interest Rate Risk
We are exposed to interest rate risk with respect to fixed and variable rate debt. At September 30, 2017 , we had $10.9 million principal amount of variable rate debt outstanding. The debt outstanding under the tax-exempt waste disposal revenue bonds is at a variable rate. 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 $10.9 million as of September 30, 2017 was 1.0%. A hypothetical 100 basis point increase in the average interest rate on our variable rate debt would increase our annual interest expense by approximately $0.1 million. Also, at September 30, 2017 , we had $3.3 billion 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 $33.4 million.
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, 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.

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 September 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

INVESTMENT MANAGEMENT AGREEMENT
among
WESTLAKE CHEMICAL CORPORATION,
WESTLAKE CHEMICAL OPCO LP,
and
WESTLAKE CHEMICAL PARTNERS LP
Dated as of August 1, 2017









INVESTMENT MANAGEMENT AGREEMENT
This INVESTMENT MANAGEMENT AGREEMENT (this “ Agreement ”) is made as of August 1, 2017, among WESTLAKE CHEMICAL CORPORATION, a Delaware corporation (“ Westlake ”), WESTLAKE CHEMICAL OPCO LP, a Delaware limited partnership (“ OpCo ”), and WESTLAKE CHEMICAL PARTNERS LP, a Delaware limited partnership (“ MLP ”).
WITNESSETH:
WHEREAS, OpCo and MLP from time to time have the need to make short-term investments of surplus cash; and
WHEREAS, OpCo and MLP expect to access more diverse range of investment options on the investment of surplus cash through joint investment with Westlake and its affiliates; and
WHEREAS, the parties have determined that it is therefore advisable and in the best interests of OpCo and MLP to authorize Westlake to establish, maintain and manage a cash and investment management system for excess cash and investments of OpCo and MLP, including authorizing Westlake to hold in Westlake’s own accounts to manage OpCo’s and MLP’s cash and investments; and
NOW, THEREFORE, in consideration of the mutual promises contained herein, the parties hereto agree as follows:
1. Investment Manager . OpCo and MLP hereby appoint Westlake as their agent with the power and discretion to act as investment manager (the “ Investment Manager ”) with respect to their excess cash, and direct the Investment Manager to invest such excess cash for the duration(s) either of them may specify from time to time.
2.      Duties, Authority and Covenants .
(a)      The Investment Manager will have the authority, as agent for and in the name of OpCo and MLP, to make investment decisions, to arrange for the executions of purchases and sales, and generally to manage the investment of the excess cash of OpCo and MLP on a fully discretionary basis (subject to compliance with the Investment Guidelines referred to in Section 3(a) below).
(b)      All funds and other assets comprising the investments of OpCo and MLP, (the “ Portfolios ”) shall be held in the name of the Investment Manager either directly by the





Investment Manager or by appropriate banks, trust companies, brokers, dealers or other custodians (each a “ Custodian ”), and all payments in respect of investment transactions shall be handled directly between the Investment Manager and its respective Custodians. OpCo and MLP consent to the commingling of the Portfolios with funds and other assets comprising investments of the Investment Manager and its other direct and indirect subsidiaries.
(c)      In the event that either OpCo or MLP requests any cash from its Portfolio earlier than the duration(s) specified in Section 1 above, the Investment Manager may liquidate the necessary portion of the Portfolio in a prudent and efficient manner to minimize any loss of capital and investment income complying with such request and transfer the requested cash to the order of OpCo or MLP, as the case may be. Notwithstanding any of the foregoing, OpCo and MLP shall receive the Earnings as calculated in Section 3(c) below.
3.      Investment Guidelines, Fees, Costs and Income .
(a)      Investment Guidelines . The Investment Manager shall adhere to the Investment Guidelines attached hereto as “Annex A” when investing excess cash on behalf of OpCo or MLP.
(b)      OpCo and MLP shall each reimburse the Investment Manager for their allocable shares of any fees and expenses paid by the Investment Manager with respect to managing their respective Portfolios, including, but not limited to costs of consultants and other professionals, whether related or unrelated to the Investment Manager.
(c)      The Investment Manager shall pay each of OpCo and MLP based on the sum of (a) the then applicable interest curve for A2/P2 US-dollar denominated commercial paper as published by Bloomberg and (b) five basis point, multiplied by the total balance of their respective Portfolio for any applicable one-day, one-week, one-month, three-month, six-month or nine-month duration (“ Earnings ”). A sample screen shot of the interest curve is attached hereto as “Annex B”.
4.      No Joint Venture, etc . The parties hereto acknowledge that this Agreement shall not create and shall not be construed to create a relationship of joint tenancy, joint venturers, co-partners, employer and employee, master and servant or any similar relationship between the parties hereto.
5.      Exculpation; Indemnification.
(a)      None of Westlake, its affiliates or any of their respective members, managers, partners, directors, officers and employees and the legal representatives of any of them (each, an “ Indemnified Affiliate ”) shall be liable to OpCo, Westlake Chemical OpCo GP LLC, Westlake

2




Chemical Partners LP or Westlake Chemical Partners GP LLC, for any mistakes of judgment or acts or omissions arising out of or in connection with any investment made or held by OpCo and MLP, as the case maybe, hereunder or this Agreement except in the case of a liability resulting from Westlake’s or such Indemnified Affiliate’s own fraud, gross negligence, willful misconduct or bad faith. Each Indemnified Affiliate may consult with counsel and accountants in respect of OpCo’s and MLP’s affairs and be fully protected and justified in any action or inaction that is taken in accordance with the advice or opinion of such counsel and accountants.
(b)      To the fullest extent permitted by law, OpCo and MLP shall indemnify and hold harmless Westlake and its Indemnified Affiliates (each, an “ IM Indemnitee ”), against any loss, cost or expense suffered or sustained by an IM Indemnitee by reason of any acts, omissions or alleged acts or omissions arising out of, or in connection with OpCo and MLP, as the case may be, any investment made or held by OpCo and MLP, as the case may be, or this Agreement, including, without limitation, any judgment, award, settlement, reasonable attorneys’ fees and other costs or expenses incurred in connection with the defense of any actual or threatened action, proceeding, or claim, provided that such acts, omissions or alleged acts or omissions upon which such actual or threatened action, proceeding or claim are based were not made in bad faith or did not constitute fraud, willful misconduct or gross negligence by such IM Indemnitee. Each of OpCo and MLP shall, in the sole discretion of Westlake, advance to any IM Indemnitee reasonable attorneys’ fees and other costs and expenses incurred in connection with the defense of any action or proceeding that arises out of such conduct. In the event that any advance described in the preceding sentence is made by OpCo and MLP, the IM Indemnitee receiving such advance shall agree to reimburse OpCo and MLP for such fees, costs and expenses to the extent that it shall be determined that it was not entitled to indemnification under this Agreement.
(c)      The provisions of this Section 6 shall survive any termination of this Agreement.
6.      Term and Termination .
(a)      This Agreement shall terminate upon the termination date set forth in a notice of termination delivered by the Investment Manager to OpCo and MLP, as the case may be, or by OpCo and MLP, as the case may be, to the Investment Manager, not less than 30 days prior to the termination date set forth therein.

(a)      Notices . All notices, reports and other communications given pursuant to this Agreement shall be in writing and shall be (i) sent by e-mail or (ii) accomplished by any other method agreed upon by the parties hereto in writing.

(c)      Amendment; Waiver . Except as otherwise provided herein, this Agreement may not be amended except by a written instrument signed by the parties hereto. Neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof. No waiver shall be effective unless it is in writing and is signed by the party asserted to have granted such waiver.
(d)      Severability . Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction only, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
(e)      Entire Agreement . This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes any prior agreement or understanding between them with respect to such subject matter.
(f)      Reliance by Third Parties . The signatures of Westlake shall be sufficient to bind OpCo and MLP, as the case may be, with respect to matters provided for under this Agreement.

4




(g)      Governing Law . This Agreement shall be governed by and construed in accordance with the laws of the State of Texas, without regard for the principles of conflict of laws thereof.
