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, 2013 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, 2013 (the " 2013 Form 10-K"), filed with the SEC on February 21, 2014. These 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, 2013 .

In the opinion of the Company's management, the accompanying unaudited consolidated interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair statement of the Company's financial position as of June 30, 2014 , its results of operations for the three and six months ended June 30, 2014 and 2013 and the changes in its cash position for the six months ended June 30, 2014 and 2013 .

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, 2014 or any other interim period. The preparation of 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.

On February 14, 2014, the Company's Board of Directors authorized a two -for-one split of the Company's common stock. Stockholders of record as of February 28, 2014 were entitled to one additional share for every share outstanding, which was distributed on March 18, 2014. The total number of authorized common stock shares and associated par value were unchanged by this stock split. All share amounts and per share data included in the accompanying consolidated financial statements and related notes have been restated to reflect the effect of the stock split.

Recent Accounting Pronouncements

Revenue from Contracts with Customers

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. The accounting standard will be effective for reporting periods beginning after December 15, 2016. 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.

5. Property, Plant and Equipment

As of June 30, 2014 , the Company had property, plant and equipment, net totaling $2,217,049 . 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.

Depreciation expense on property, plant and equipment of $39,859 and $32,615 is included in cost of sales in the consolidated statements of operations for the three months ended June 30, 2014 and 2013 , respectively. Depreciation expense on property, plant and equipment of $77,920 and $63,535 is included in cost of sales in the consolidated statements of operation for the six months ended June 30, 2014 and 2013 , respectively.

6. Other Assets

Amortization expense on intangible and other assets of $9,008 and $7,959 is included in the consolidated statements of operations for the three months ended June 30, 2014 and 2013 , respectively. Amortization expense on intangible and other assets of $17,284 and $12,760 is included in the consolidated statements of operations for the six months ended June 30, 2014 and 2013 , respectively.

Goodwill

Goodwill for the Olefins segment was $29,990 at June 30, 2014 and December 31, 2013 . Goodwill for the Vinyls segment was $32,026 at June 30, 2014 and December 31, 2013 . There were no changes in the carrying amount of goodwill by operating segments for the six months ended June 30, 2014 .

The annual impairment test for the Olefins segment's recorded goodwill was performed as of October 31, 2013 . The annual impairment test for the Vinyls segment's recorded goodwill was performed as of April 30, 2014 . The impairment test

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

indicated that the Vinyls segment's goodwill was not impaired. There has been no impairment of the Vinyls segment's goodwill since it was initially recorded.

Vinyls Segment Goodwill

The fair value of the pipe and foundation building products business, the reporting unit assessed, was calculated using both a discounted cash flow methodology and a market value methodology. The discounted cash flow projections were based on a 10 -year forecast, from 2014 to 2023 , to reflect the cyclicality of the North American housing and construction markets as the Company's pipe and foundation building products business is significantly influenced by said markets. The forecast was based on historical results and estimates by management, including their strategic and operational plans, and assumed a gradual increase in financial performance based on a housing market recovery in the United States. The future cash flows were discounted to present value using a discount rate of 8.8% .

The significant assumptions used in determining the fair value of the reporting unit using the market value methodology include the determination of appropriate market comparables and the estimated multiples of EBITDA a willing buyer is likely to pay.

Even if the fair value of the reporting unit decreased by 10% , the carrying value of the reporting unit would not exceed its fair value.

7. Long-Term Debt

Long-term debt consists of the following:



	June 30, 2014		December 31, 2013
3.60% senior notes due 2022	$	249,049	$	248,990
6 ½% senior notes due 2029	100,000		100,000

6 ½% senior notes due 2035 (the "6 ½% GO Zone Senior Notes Due 2035")	89,000		89,000
6 ½% senior notes due 2035 (the "6 ½% IKE Zone Senior Notes Due 2035")	65,000		65,000
Loan related to tax-exempt waste disposal revenue bonds due 2027	10,889		10,889
Long-term debt, net	$	763,938	$	763,879

Revolving Credit Facility

The Company has a $400,000 senior secured revolving credit facility. The facility includes a provision permitting the Company to increase the size of the facility, up to four times, in increments of at least $25,000 each (up to a maximum of $150,000 ) under certain circumstances if lenders agree to commit to such an increase. At June 30, 2014 , the Company had no borrowings outstanding under the revolving credit facility. Any borrowings under the facility will bear interest at either LIBOR plus a spread ranging from 1.75% to 2.25% or a base rate plus a spread ranging from 0.25% to 0.75% . The revolving credit facility also requires an unused commitment fee of 0.375% per annum. All interest rates under the facility are subject to monthly grid pricing adjustments based on prior month average daily loan availability. The revolving credit facility matures on September 16, 2016. As of June 30, 2014 , the Company had outstanding letters of credit totaling $17,773 and borrowing availability of $382,227 under the revolving credit facility.

Subsequent to June 30, 2014, the Company entered into a third amendment and restatement to the revolving credit facility. See Note 18 for additional information.

8. Stock-Based Compensation

Under the Westlake Chemical Corporation 2013 Omnibus Incentive Plan (as amended and restated, the "2013 Plan"), all employees and nonemployee directors of the Company, as well as certain individuals who have agreed to become the Company's employees, are eligible for awards. Shares of common stock may be issued as authorized in the 2013 Plan. At the discretion of the administrator of the 2013 Plan, employees and nonemployee directors may be granted awards in the form of stock options, stock appreciation rights, stock awards, restricted stock units or cash awards (any of which may be a performance award). Total stock-based compensation expense related to the 2013 Plan was $2,289 and $1,626 for the three months ended June 30, 2014 and 2013 , respectively, and $4,511 and $3,124 for the six months ended June 30, 2014 and 2013 , respectively.

9. Derivative Instruments

Commodity Risk Management

The Company uses derivative instruments to reduce price volatility risk on raw materials and products as a substantial portion of its raw materials and products are commodities whose prices fluctuate as market supply and demand fundamentals change. Business strategies to protect against such instability include ethylene product feedstock flexibility and moving downstream into the olefins and vinyls products where pricing is more stable. The Company does not use derivative instruments to engage in speculative activities.

For derivative instruments that are designated and qualify as fair value hedges, the gains or losses on the derivative instruments, as well as the offsetting losses or gains on the hedged items attributable to the hedged risk, were included in cost of sales in the consolidated statements of operations for the three and six months ended June 30, 2013 . The Company had no derivative instruments that were designated as fair value hedges for the three and six months ended June 30, 2014 .

Gains and losses from changes in the fair value of derivative instruments that are not designated as hedging instruments were included in gross profit in the consolidated statements of operations for the three and six months ended June 30, 2014 and 2013 .

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).

Disclosures related to the Company's derivative assets and derivative liabilities subject to enforceable master netting arrangements have not been presented as they are not material to the Company's consolidated balance sheets at June 30, 2014 and December 31, 2013 .

The fair values of derivative instruments in the Company's consolidated balance sheets were as follows:



	Derivative Assets
	Balance Sheet Location	Fair Value as of
	Balance Sheet Location	June 30, 2014		December 31, 2013

10. Fair Value Measurements

The Company reports certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Under the accounting guidance for fair value measurements, inputs used to measure fair value are classified in one of three levels:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The following tables summarize, by level within the fair value hierarchy, the Company's assets and liabilities that were accounted for at fair value on a recurring basis:



	June 30, 2014
	Level 1		Level 2			Total
Derivative instruments
Risk management assets - Commodity forward contracts	$	430	$	507		$	937
Risk management liabilities - Commodity forward contracts	—		(924		)	(924		)
Available-for-sale marketable securities	18,879		—			18,879

	December 31, 2013
	Level 1		Level 2			Total
Derivative instruments
Risk management assets - Commodity forward contracts	$	48	$	248		$	296
Risk management liabilities - Commodity forward contracts	—		(176		)	(176		)
Available-for-sale marketable securities	91,595		147,793			239,388

The Level 2 measurements for the Company's commodity contracts are derived using forward curves supplied by industry-recognized and unrelated third-party services. The Level 2 measurements for the Company's available-for-sale securities are derived using market-based pricing provided by unrelated third-party services.

There were no transfers in or out of Levels 1 and 2 of the fair value hierarchy for the six months ended June 30, 2014 and 2013 .

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 long-term debt, all of which are recorded at carrying value. The amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, net and accounts payable approximate their fair value due to the short maturities of these instruments. The carrying and fair values of the Company's long-term debt are summarized in the table below. The Company's long-term debt instruments are publicly-traded. A market approach, based upon quotes from financial reporting services, is used to measure the fair value of the Company's long-term debt. Because the Company's long-term debt instruments may not be actively traded, the inputs used to measure the fair value of the Company's long-term debt are classified as Level 2 inputs within the fair value hierarchy.

11. Income Taxes

The effective income tax rate was 34.9% for the six months ended June 30, 2014 . The effective income tax rate for the 2014 period was below the U.S. federal statutory rate of 35.0% primarily due to state tax credits and the domestic manufacturing deduction, mostly offset by state income taxes. The effective income tax rate was 36.1% for the six months ended June 30, 2013 . The effective income tax rate for the 2013 period was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction.

There was no material change to the total gross unrecognized tax benefits for the six months ended June 30, 2014 . Management anticipates that all of the gross unrecognized tax benefits of $2,501 will be recognized within the next twelve months due to expiring statutes of limitations. The impact from the recognition of these tax benefits on the Company's effective tax rate is expected to be immaterial.

The Company recognizes penalties and interest accrued related to unrecognized tax benefits in income tax expense. As of June 30, 2014 , the Company had no material accrued interest and penalties related to uncertain tax positions.

The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company is no longer subject to examinations by tax authorities before the year 2007.

12. Earnings per Share

The Company has unvested shares of restricted stock and 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.



	Three Months Ended June 30,						Six Months Ended June 30,
	2014			2013			2014			2013
Net income	$	169,443		$	145,816		$	327,475		$	269,163
Less:
Net income attributable to participating securities	(360		)	(512		)	(746		)	(1,091		)
Net income attributable to common shareholders	$	169,083		$	145,304		$	326,729		$	268,072

The following table reconciles the denominator for the basic and diluted earnings per share computations shown in the consolidated statements of operations:

(1)	Share amounts and per share data for the three and six months ended June 30, 2013 have been restated to reflect the effect of a two -for-one stock split on March 18, 2014. See Note 1 for additional information.

Excluded from the computation of diluted earnings per share are options to purchase 134,938 and 142,912 shares of common stock for the three months ended June 30, 2014 and 2013 , respectively, and 102,480 and 108,000 shares of common stock for the six months ended June 30, 2014 and 2013 , respectively. These options were outstanding during the periods reported but were excluded because the effect of including them would have been antidilutive.

15. Commitments and Contingencies

The Company is subject to environmental laws and regulations that can impose civil and criminal sanctions and that may require it to mitigate the effects of contamination caused by the release or disposal of hazardous substances into the environment. Under one law, the U.S. Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), an owner or operator of property may be held strictly liable for remediating contamination without regard to whether that person caused the contamination, and without regard to whether the practices that resulted in the contamination were legal at the time they occurred. Because several of the Company's production sites have a history of industrial use, it is impossible to predict precisely what effect these legal requirements will have on the Company.

Contract Disputes with Goodrich and PolyOne. In connection with the 1990 and 1997 acquisitions of the Goodrich Corporation ("Goodrich") chemical manufacturing complex in Calvert City, Kentucky, Goodrich agreed to indemnify the Company for any liabilities related to preexisting contamination at the complex. For its part, the Company agreed to indemnify Goodrich for post-closing contamination caused by the Company's operations. The soil and groundwater at the complex, which does not include the Company's nearby polyvinyl chloride ("PVC") facility, had been extensively contaminated under Goodrich's operations. In 1993, Goodrich spun off the predecessor of PolyOne Corporation ("PolyOne"), and that predecessor assumed Goodrich's indemnification obligations relating to preexisting contamination.

In 2003, litigation arose among the Company, Goodrich and PolyOne with respect to the allocation of the cost of remediating contamination at the site. The parties settled this litigation in December 2007 and the case was dismissed. In the settlement the parties agreed that, among other things: (1) PolyOne would pay 100% of the costs (with specified exceptions), net of recoveries or credits from third parties, incurred with respect to environmental issues at the Calvert City site from August 1, 2007 forward; (2) either the Company or PolyOne might, from time to time in the future (but not more than once every five years), institute an arbitration proceeding to adjust that percentage; and (3) the Company and PolyOne would negotiate a new environmental remediation utilities and services agreement to cover the Company's provision to, or on behalf of, PolyOne of certain environmental remediation services at the site. The current environmental remediation activities at the

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

Calvert City complex do not have a specified termination date but are expected to last for the foreseeable future. The costs incurred by the Company that have been invoiced to PolyOne to provide the environmental remediation services were $3,284 in 2013 . By letter dated March 16, 2010, PolyOne notified the Company that it was initiating an arbitration proceeding under the settlement agreement. In this proceeding, PolyOne seeks to readjust the percentage allocation of costs and to recover approximately $1,400 from the Company in reimbursement of previously paid remediation costs. The arbitration is currently stayed.

State Administrative Proceedings. There are several administrative proceedings in Kentucky involving the Company, Goodrich and PolyOne related to the same manufacturing complex in Calvert City. In 2003, the Kentucky Environmental and Public Protection Cabinet (the "Cabinet") re-issued Goodrich's Resource Conservation and Recovery Act ("RCRA") permit which requires Goodrich to remediate contamination at the Calvert City manufacturing complex. Both Goodrich and PolyOne challenged various terms of the permit in an attempt to shift Goodrich's clean-up obligations under the permit to the Company. The Company intervened in the proceedings. The Cabinet has suspended all corrective action under the RCRA permit in deference to a remedial investigation and feasibility study ("RIFS") being conducted, under the auspices of the U.S. Environmental Protection Agency ("EPA"), pursuant to an Administrative Settlement Agreement ("AOC"), which became effective on December 9, 2009. See "Federal Administrative Proceedings" below. The proceedings have been postponed. Periodic status conferences will be held to evaluate whether additional proceedings will be required.

Federal Administrative Proceedings. In May 2009, the Cabinet sent a letter to the EPA requesting the EPA's assistance in addressing contamination at the Calvert City site under CERCLA. In its response to the Cabinet also in May 2009, the EPA stated that it concurred with the Cabinet's request and would incorporate work previously conducted under the Cabinet's RCRA authority into the EPA's cleanup efforts under CERCLA. Since 1983, the EPA has been addressing contamination at an abandoned landfill adjacent to the Company's plant which had been operated by Goodrich and which was being remediated pursuant to CERCLA. During the past three years, the EPA has directed Goodrich and PolyOne to conduct additional investigation activities at the landfill and at the Company's plant. In June 2009, the EPA notified the Company that the Company may have potential liability under section 107(a) of CERCLA at its plant site. Liability under section 107(a) of CERCLA is strict and joint and several. The EPA also identified Goodrich and PolyOne, among others, as potentially responsible parties at the plant site. The Company negotiated, in conjunction with the other potentially responsible parties, the AOC and an order to conduct the RIFS. On July 12, 2013, the parties submitted separate draft RIFS reports to the EPA. The EPA has hired a contractor to complete the remedial investigation report.

Monetary Relief . Except as noted above with respect to the settlement of the contract litigation among the Company, Goodrich and PolyOne, none of the court, the Cabinet nor the EPA has established any allocation of the costs of remediation among the various parties that are involved in the judicial and administrative proceedings discussed above. At this time, the Company is not able to estimate the loss or reasonable possible loss, if any, on the Company's financial statements that could result from the resolution of these proceedings. Any cash expenditures that the Company might incur in the future with respect to the remediation of contamination at the complex would likely be spread out over an extended period. As a result, the Company believes it is unlikely that any remediation costs allocable to it will be material in terms of expenditures made in any individual reporting period.

In addition to the matters described above, the Company is involved in various routine legal proceedings incidental to the conduct of its business. The Company does not believe that any of these routine legal proceedings will have a material adverse effect on its financial condition, results of operations or cash flows.

16. Share Capital

Common Stock

On May 16, 2014, the stockholders of the Company approved an amendment to the Company's Amended and Restated Certificate of Incorporation to increase the Company's authorized shares of common stock from 150,000,000 shares to 300,000,000 shares, par value $0.01 per share. The Company is now authorized to issue 300,000,000 shares of common stock, par value $0.01 per share, of which 134,681,372 and 134,580,208 shares (on a post-split basis) were issued as of June 30, 2014 and December 31, 2013 , respectively. Each share of common stock entitles the holder to one vote on all matters on which holders are permitted to vote, including the election of directors.

Stock Repurchase Program

In August 2011, the Company's Board of Directors authorized a stock repurchase program of the Company’s common stock totaling $100,000 (the "2011 Program"). Purchases under the 2011 Program began in September 2011. As of June 30, 2014 and December 31, 2013 , the Company had repurchased 1,252,922 shares of its common stock (on a post-split basis) under this program. Shares repurchased under the 2011 Program are held by the Company as treasury stock and may be used for general corporate purposes, including for the 2013 Omnibus Incentive Plan. Beginning in May 2014, the Company began issuing treasury shares to employees and nonemployee directors for options exercised and for the release of restricted stock units. The cost of treasury shares issued was determined using the specific identification method.

17. 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.

18. Subsequent Events

Initial Public Offering of WLKP

In March 2014, the Company formed Westlake Chemical Partners LP ("WLKP") to operate, acquire and develop ethylene production facilities and related assets. On August 4, 2014, WLKP closed its initial public offering of 12,937,500 common units at a price of $24.00 per unit, which included 1,687,500 units purchased by the underwriters through an over-allotment option. Net proceeds to WLKP from the sale of the units was approximately $286,263 , net of underwriting discounts, structuring fees and estimated offering expenses of approximately $24,237 . At the consummation of this offering, WLKP's assets consist of a 10.6% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), as well as the general partner interest in OpCo. The Company retained an 89.4% limited partner interest in OpCo and a significant interest in WLKP. OpCo used the net proceeds from the purchase of its limited partner interest to establish a cash reserve of $55,400 for turnaround expenditures, to reimburse approximately $155,700 for capital expenditures incurred by the Company with respect to certain of the assets contributed to OpCo and to repay intercompany debt to the Company of approximately $75,144 . The initial public offering represented the sale of a 47.8% interest in WLKP.

Amendment and Restatement of the Revolving Credit Facility

In July 2014, the Company entered into a third amendment and restatement to the revolving credit facility. The amendment and restatement extended the scheduled maturity date of the facility from September 16, 2016 to July 17, 2019, reduced the interest rate and facility fee payable under the facility and, among other things, amended the covenants restricting the Company’s ability to make distributions and acquisitions and investments.

Acquisition of Vinnolit Holdings GmbH Group

In May 2014, the Company announced that it had entered into a definitive agreement to acquire German-based Vinnolit Holdings GmbH and its subsidiary companies ("Vinnolit") for approximately €490,000 from several entities associated with Advent International Corporation. Vinnolit is an integrated global leader in specialty PVC resins, with a combined annual capacity of 1.7 billion pounds of PVC, including specialty paste and suspension grades, 1.5 billion pounds of vinyl chloride monomer ("VCM") and 1.0 billion pounds of caustic soda. This transaction closed on July 31, 2014.

19. Guarantor Disclosures

The Company's payment obligations under the 3.60% senior notes due 2022 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 the 3.60% senior notes due 2022 in excess of $5,000 (the "Guarantor Subsidiaries"). Each Guarantor Subsidiary is 100% owned by Westlake Chemical Corporation. 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 Guarantor Subsidiaries and the remaining subsidiaries that do not guarantee the 3.60% senior notes due 2022 (the "Non-Guarantor Subsidiaries"), together with consolidating eliminations necessary to present the Company's results on a consolidated basis.

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 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, 2013 (the " 2013 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 manufacturer and marketer of basic chemicals, vinyls, polymers and fabricated building products. Our two principal operating segments are Olefins and Vinyls. We use the majority of our internally-produced basic chemicals to produce higher value-added chemicals and building products.

Since 2009 and continuing through the second quarter of 2014, a cost advantage for ethane-based ethylene producers over naphtha-based ethylene producers has allowed a strong export market for ethylene derivatives and higher margins for North American chemical producers, including Westlake. Increased global demand for polyethylene in recent years in particular has resulted in improved operating margins and cash flow for our Olefins segment.

Continued slow recovery in the U.S. construction markets and budgetary constraints in municipal spending have contributed to lower domestic demand for our vinyls products. However, since late 2010, the polyvinyl chloride ("PVC") industry has experienced an increase in PVC resin export demand, driven largely by more competitive feedstock and energy cost positions in North America. As a consequence, domestic PVC resin industry operating rates have improved since 2010, largely due to higher PVC resin export shipments. In the fourth quarter of 2013, we started up our new world scale Geismar, Louisiana chlor-alkali plant. In April 2014, we completed the expansion and conversion of our Calvert City, Kentucky ethylene plant to ethane feedstock (see further discussion in "Recent Developments" below). The completion of these two projects is expected to improve the profitability of our Vinyls segment.

The U.S. and global economic environment appears to be slowly improving, but depending on the performance of both economies in the remainder of 2014 and beyond, could still have a negative effect on our financial condition, results of operations or cash flows.

Recent Developments

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 closed its initial public offering of 12,937,500 common units at a price of $24.00 per unit, which included 1,687,500 units purchased by the underwriters through an over-allotment option. Net proceeds to WLKP from the sale of the units was approximately $286.3 million, net of underwriting discounts, structuring fees and estimated offering expenses of approximately $24.2 million. At the consummation of this offering, WLKP's assets consist of a 10.6% limited partner interest in Westlake Chemical OpCo LP ("OpCo"), as well as the general partner interest in OpCo. We retained an 89.4% limited partner interest in OpCo and a significant interest in WLKP. OpCo used the net proceeds from the purchase of its limited partner interest to establish a cash reserve of $55.4 million for turnaround expenditures, to reimburse us approximately $155.7 million for capital expenditures incurred with respect to certain of the assets contributed to OpCo and to repay intercompany debt of approximately $75.1 million. The initial public offering represented the sale of a 47.8% interest in WLKP.

In May 2014, we announced that we had entered into a definitive agreement to acquire German-based Vinnolit Holdings GmbH and its subsidiary companies ("Vinnolit") from several entities associated with Advent International Corporation. Vinnolit is an integrated global leader in specialty PVC resins, with a combined annual capacity of 1.7 billion pounds of PVC, including specialty paste and suspension grades, 1.5 billion pounds of vinyl chloride monomer ("VCM") and 1.0 billion pounds of caustic soda. The purchase price of approximately €490.0 million was financed using existing Westlake cash and credit facilities. This transaction closed on July 31, 2014.

In April 2014, we completed the previously announced feedstock conversion and ethylene expansion project at our Calvert City ethylene plant. With the completion of this project, our Calvert City ethylene plant now utilizes cost-advantaged ethane feedstock and increased its capacity by approximately 180 million pounds annually. This expansion and feedstock conversion project is expected to enhance our vinyl chain integration and leverage low cost ethane being developed in the Marcellus shale area. The ethylene plant and other production facilities at our Calvert City complex were shut down for approximately 19 days (5 days during the second quarter of 2014) as a result of the feedstock conversion and ethylene expansion project and other planned maintenance turnaround activities. Income from operations for the first quarter of 2014 was negatively impacted by the lost sales, lower production rates, unabsorbed fixed manufacturing costs and other costs

Summary

For the quarter ended June 30, 2014 , net income was $169.4 million , or $1.26 per diluted share, on net sales of $998.6 million . This represents an increase in net income of $23.6 million , or $0.17 per diluted share, compared to the quarter ended June 30, 2013 net income of $145.8 million , or $1.09 per diluted share, on net sales of $939.0 million . Net sales for the second quarter of 2014 increased by $59.6 million compared to net sales for the second quarter of 2013 , mainly attributable to higher sales prices for most of our major Olefins products and higher sales volumes for polyethylene, styrene and caustic soda, partially offset by lower sales volumes for PVC resin and ethylene co-products. Ethylene co-products sales volumes were lower for the second quarter of 2014 primarily due to the ethane feedstock currently utilized at our Calvert City ethylene plant following the completion of the feedstock conversion project. Income from operations was $266.8 million for the second quarter of 2014 as compared to $235.2 million for the second quarter of 2013 . Income from operations for the second quarter of 2014 benefited primarily from improved olefins integrated product margins, as higher sales prices more than offset the increase in feedstock and energy costs, and higher olefins sales volumes. The second quarter 2014 income from operations was negatively impacted by higher cost inventory that was produced from propane feedstock in the first quarter of 2014 that flowed through cost of sales in the second quarter of 2014, costs associated with the first quarter 2014 maintenance turnaround and other activities at our Calvert City complex that carried over into the second quarter of 2014 and lower PVC resin sales volumes in the second quarter of 2014 as compared to the second quarter of 2013. In addition, the second quarter of 2014 was negatively impacted by an unplanned outage at one of our ethylene units in Lake Charles, Louisiana.

For the six months ended June 30, 2014 , net income was $327.5 million , or $2.44 per diluted share, on net sales of $2,026.3 million . This represents an increase in net income of $58.3 million , or $0.43 per diluted share, from the six months ended June 30, 2013 net income of $269.2 million , or $2.01 per diluted share, on net sales of $1,803.7 million . Net sales for the six months ended June 30, 2014 increased by $222.6 million compared to the prior year period mainly due to higher sales prices and sales volumes for most of our major Olefins products and sales contributed by our specialty PVC pipe business, which we acquired in May 2013, partially offset by lower ethylene co-products, PVC resin and styrene sales volumes. Income from operations was $514.8 million for the six months ended June 30, 2014 as compared to $429.3 million for the six months ended June 30, 2013 , an increase primarily attributable to improved olefins integrated product margins and higher olefins sales volumes. The increase in income from operations for the six months ended June 30, 2014 was partially offset by the lost sales, lower production rates, unabsorbed fixed manufacturing costs and other costs associated with the maintenance turnaround at our Calvert City complex and our Calvert City ethylene plant’s feedstock conversion and expansion project during the first quarter of 2014.

RESULTS OF OPERATIONS

Second Quarter 2014 Compared with Second Quarter 2013

Net Sales . Net sales increased by $59.6 million , or 6.3% , to $998.6 million in the second quarter of 2014 from $939.0 million in the second quarter of 2013 , primarily attributable to higher sales prices for most of our major Olefins products and higher sales volumes for polyethylene, styrene and caustic soda, partially offset by lower sales volumes for PVC resin and ethylene co-products. Average sales prices for the second quarter of 2014 increased by 5.2% as compared to the second quarter of 2013 . Overall sales volumes increased by 1.1% as compared to the second quarter of 2013 .

Gross Profit . Gross profit margin percentage increased to 30.6% for the second quarter of 2014 from 29.1% for the second quarter of 2013 , mainly due to improved olefins integrated product margins as an increase in sales prices outpaced increases in feedstock and energy costs. Our raw material cost in both segments normally tracks industry prices, which experienced an increase of 6.5% for ethane as compared to the second quarter of 2013 . Sales prices increased an average of 5.2% for the second quarter of 2014 as compared to the second quarter of 2013 . The improvement in gross profit margin for the second quarter of 2014 was partially offset by the negative impact of higher cost inventory that was produced from propane

feedstock in the first quarter of 2014, costs associated with the first quarter 2014 maintenance turnaround and other activities at our Calvert City complex that carried over into the second quarter of 2014 and the lost production resulting from the maintenance turnaround activities that extended into the second quarter of 2014, which resulted in lower PVC resin sales volumes in the second quarter of 2014 as compared to the prior year period. In addition, the second quarter of 2014 was negatively impacted by an unplanned outage at one of our ethylene units in Lake Charles.

Selling, General and Administrative Expenses . Selling, general and administrative expenses for the second quarter of 2014 of $39.2 million increased marginally by $0.9 million as compared to the second quarter of 2013 , as an increase in consulting and professional fees were mostly offset by a decrease in the provision for doubtful accounts.

Interest Expense . Interest expense increased by $4.2 million to $9.5 million in the second quarter of 2014 from $5.3 million in the second quarter of 2013 largely as a result of decreased capitalized interest on major capital projects as compared to the prior year period. Debt balances remained relatively unchanged from the prior year period.

Other Income (Expense), Net . Other income (expense), net was net income of $4.6 million in the second quarter of 2014 compared to net expense of $0.1 million in the second quarter of 2013 , mainly due to higher income from our equity method investments, higher gain from sales of securities and lower losses on foreign exchange.

Income Taxes. The effective income tax rate was 35.3% for the second quarter of 2014 . The effective income tax rate for the second quarter of 2014 was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, mostly offset by the domestic manufacturing deduction. The effective income tax rate was 36.5% for the second quarter of 2013 . The effective income tax rate for the second quarter of 2013 was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction.

Olefins Segment

Net Sales . Net sales increased by $75.8 million , or 12.2% , to $699.1 million in the second quarter of 2014 from $623.3 million in the second quarter of 2013 , predominantly due to higher sales prices for most of our major products and higher sales volumes for polyethylene and styrene as compared to the prior year period. Average sales prices for the Olefins segment increased by 7.4% in the second quarter of 2014 as compared to the second quarter of 2013 . Average sales volumes for the Olefins segment increased by 4.8% in the second quarter of 2014 as compared to the second quarter of 2013 .

Income from Operations . Income from operations increased by $51.0 million , or 27.2% , to $238.7 million in the second quarter of 2014 from $187.7 million in the second quarter of 2013 . This increase was mainly attributable to higher olefins integrated product margins in the second quarter of 2014 as compared to the prior year period, as the increase in sales prices outpaced increases in feedstock and energy costs. In addition, second quarter 2014 income from operations benefited from higher polyethylene and styrene sales volumes as compared to the second quarter of 2013. Second quarter 2014 income from operations was negatively impacted by an unplanned outage at one of our ethylene units in Lake Charles. Trading activity in the second quarter of 2014 resulted in a gain of $0.2 million as compared to a gain of $9.4 million in the second quarter of 2013 .

Vinyls Segment

Net Sales . Net sales decreased by $16.2 million , or 5.1% , to $299.5 million in the second quarter of 2014 from $315.7 million in the second quarter of 2013 . This decrease was mainly attributable to the lower ethylene co-products volumes produced, and consequently sold, as a result of the change in feedstock utilized at our Calvert City ethylene plant from propane to ethane, following the completion of the feedstock conversion project. In addition, PVC resin sales volumes were lower in the second quarter of 2014 as compared to the prior year period. Average sales prices for the Vinyls segment increased by 1.0% in the second quarter of 2014 as compared to the second quarter of 2013 . Average sales volumes for the Vinyls segment decreased by 6.2% in the second quarter of 2014 as compared to the second quarter of 2013 .

Income from Operations. Income from operations decreased by $14.8 million , or 28.0% , to $38.1 million in the second quarter of 2014 from $52.9 million in the second quarter of 2013 . The second quarter 2014 income from operations was negatively impacted by higher cost inventory that was produced from propane feedstock in the first quarter of 2014 that flowed through cost of sales in the second quarter of 2014 and costs associated with the first quarter 2014 maintenance turnaround and other activities at our Calvert City complex that carried over into the second quarter of 2014. In addition, second quarter 2014 income from operations was negatively impacted by lower PVC resin sales volumes primarily caused by lost production resulting from the first quarter 2014 maintenance turnaround activities at our Calvert City complex that extended into the second quarter of 2014.

Ethylene co-products sales volumes were lower for the six months ended June 30, 2014, as compared to the six months ended June 30, 2013, primarily due to the planned shut down of our Calvert City ethylene plant as a result of the feedstock conversion and expansion project and the ethane feedstock currently utilized at our Calvert City ethylene plant following the completion of the feedstock conversion project. Average sales prices for the six months ended June 30, 2014 increased by 6.2% as compared to the six months ended June 30, 2013 . Overall sales volumes for the six months ended June 30, 2014 increased by 6.1% as compared to the six months ended June 30, 2013 .

Gross Profit . Gross profit margin percentage of 29.3% for the six months ended June 30, 2014 increased from the 27.8% gross profit margin percentage for the six months ended June 30, 2013 . The improvement in gross profit margin percentage was predominantly due to the improved olefins integrated product margins primarily as a result of the increased ethylene production at our Lake Charles complex after the first quarter 2013 completion of the Petro 2 ethylene unit expansion and its conversion to 100% ethane feedstock capability. In addition, olefins integrated product margins for the six months ended June 30, 2014 benefited from an increase in sales prices that outpaced increases in feedstock and energy costs as compared to the prior year period. Our raw material cost in both segments normally tracks industry prices, which experienced an increase of 19.1% for ethane and an increase of 33.3% for propane as compared to the six months ended June 30, 2013 . Sales prices increased an average of 6.2% for the six months ended June 30, 2014 as compared to the prior year period. The gross profit margin for the six months ended June 30, 2014 was negatively impacted by the lost sales, lower production rates, unabsorbed fixed manufacturing costs and other costs associated with the maintenance turnaround at our Calvert City complex and our Calvert City ethylene plant’s feedstock conversion and expansion project.

Selling, General and Administrative Expenses . Selling, general and administrative expenses for the six months ended June 30, 2014 increased by $6.1 million as compared to the six months ended June 30, 2013 , mainly attributable to an increase in payroll and related labor costs, including incentive compensation, and an increase in consulting and professional fees, partially offset by a decrease in the provision for doubtful accounts.

Interest Expense . Interest expense increased by $7.1 million to $18.7 million for the six months ended June 30, 2014 , largely as a result of decreased capitalized interest on major capital projects as compared to the prior year period. Debt balances remained relatively unchanged from the prior year period.

Other Income, Net . Other income, net increased by $3.7 million to $7.1 million for the six months ended June 30, 2014 from $3.4 million for the six months ended June 30, 2013 . The increase was principally due to higher income from our equity method investments, higher gain from sales of securities and lower losses on foreign exchange as compared to the prior year period.

Income Taxes. The effective income tax rate was 34.9% for the six months ended June 30, 2014 . The effective income tax rate for the 2014 period was below the U.S. federal statutory rate of 35.0% primarily due to state tax credits and the domestic manufacturing deduction, mostly offset by state income taxes. The effective income tax rate was 36.1% for the six months ended June 30, 2013 . The effective income tax rate for the 2013 period was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction.

Olefins Segment

Net Sales . Net sales increased by $215.7 million , or 17.9% , to $1,421.9 million for the six months ended June 30, 2014 from $1,206.2 million for the six months ended June 30, 2013 , mainly driven by higher sales prices and sales volumes for most of our major products. Olefins sales volumes for the six months ended June 30, 2013 were lower primarily due to the first quarter 2013 turnaround and expansion of the Lake Charles Petro 2 ethylene unit. Average sales prices for the Olefins segment increased by 9.2% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 . Average sales volumes for the Olefins segment increased by 8.7% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 .

Income from Operations .

Further,

Table of Contents

income from operations for the six months ended June 30, 2014 benefited from higher sales volumes for most of our major products and improved production rates for most plants as compared to the prior year period. Trading activity for the six months ended June 30, 2014 resulted in a loss of $0.4 million as compared to a gain of $16.7 million for the prior year period. Income from operations for the six months ended June 30, 2013 was negatively impacted by the lost production, unabsorbed fixed manufacturing costs and other costs associated with the turnaround and expansion of the Lake Charles Petro 2 ethylene unit.

Vinyls Segment

Net Sales . Net sales increased by $6.9 million , or 1.2% , to $604.4 million for the six months ended June 30, 2014 from $597.5 million for the six months ended June 30, 2013 . This increase was primarily attributable to sales contributed by our specialty PVC pipe business, mostly offset by lower ethylene co-products and PVC resin sales volumes and lower caustic sales prices. Ethylene co-products sales volumes were lower for the six months ended June 30, 2014, as compared to the six months ended June 30, 2013, primarily due to the planned shut down of our Calvert City ethylene plant as a result of the feedstock conversion and expansion project and the ethane feedstock currently utilized at our Calvert City ethylene plant following the completion of the feedstock conversion project. Average sales prices for the Vinyls segment increased by 0.2% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 , while average sales volumes increased by 0.9% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 .

Income from Operations. Income from operations decreased by $79.6 million to $17.0 million for the six months ended June 30, 2014 from $96.6 million for the six months ended June 30, 2013 . This decrease was primarily driven by the lost sales, lower production rates and the expensing of $20.4 million related to unabsorbed fixed manufacturing costs and other costs associated with the maintenance turnaround at our Calvert City complex and our Calvert City ethylene plant’s feedstock conversion and expansion project. In addition, income from operations for the six months ended June 30, 2014 was negatively impacted by lower PVC resin sales volumes, lower caustic sales prices, the severe winter weather experienced in early 2014 and prior to the completion of the Calvert City ethylene plant’s feedstock conversion project, lower vinyls integrated product margins attributable to significantly higher propane costs, as average industry prices for propane increased by 50.2% in the first quarter of 2014 as compared to the prior year period.

CASH FLOW DISCUSSION FOR THE SIX MONTHS ENDED JUNE 30, 2014 AND 2013

Cash Flows

Operating Activities

Operating activities provided cash of $432.2 million in the first six months of 2014 compared to cash provided of $255.5 million in the first six months of 2013 . The $176.7 million increase in cash flows from operating activities was mainly due to an increase in income from operations and a decrease in the use of cash for working capital purposes. Income from operations increased by $85.5 million in the first six months of 2014 primarily as a result of higher olefins integrated product margins as compared to the prior year period. Cash flows from operating activities for the first six months of 2013 was negatively impacted by deferred turnaround costs from the turnaround of one of our Lake Charles ethylene units. 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, used cash of $6.9 million in the first six months of 2014 , compared to $98.5 million of cash used in the first six months of 2013 , a favorable change of $91.6 million . The change was mainly due to a decrease in inventory during the 2014 period and a smaller increase in accounts receivable during the 2014 period as compared to the prior year period.

Investing Activities

Net cash provided by investing activities during the first six months of 2014 was $7.5 million as compared to net cash used for investing activities of $388.9 million in the first six months of 2013 . Capital expenditures were $216.9 million in the first six months of 2014 compared to $297.9 million in the first six months of 2013 , a decrease mainly attributable to the completion of the new chlor-alkali plant at our Geismar facility in December 2013. Capital expenditures in the first six months of 2014 were mainly incurred on the feedstock conversion and ethylene expansion project and PVC plant expansion project at our Calvert City complex and the planned upgrade and expansion of the second ethylene unit at our Lake Charles complex. Capital expenditures in the first six months of 2013 were mainly incurred on the construction of the new Geismar chlor-alkali plant, the expansion of the first ethylene unit at our Lake Charles complex and the feedstock conversion and ethylene furnaces modernization projects at our Calvert City complex. The remaining capital expenditures in the first six months of 2014 and 2013 primarily related to projects to improve production capacity or reduce costs, maintenance and safety projects and environmental projects at our various facilities. Purchases of securities in the first six months of 2014 totaled $117.3 million and were comprised of corporate and U.S. government debt securities and equity securities. We also received aggregate

Table of Contents

proceeds of $342.0 million from the sales and maturities of our investments in the first six months of 2014 . The activity during the first six months of 2013 was primarily related to the acquisition of our specialty PVC pipe business and the purchases of, and the receipt of proceeds from the maturities of, short-term commercial paper.

Financing Activities

Net cash used for financing activities during the first six months of 2014 was $25.0 million as compared to net cash used of $31.2 million in the first six months of 2013 . The activity during the first six months of 2014 was primarily related to the $33.6 million payment of cash dividends, partially offset by proceeds of $4.2 million from the exercise of stock options. The activity during the first six months of 2013 was mainly related to the $25.1 million payment of cash dividends and the $13.3 million of cash used for the repurchases of shares of our common stock, partially offset by proceeds from the exercise of stock options.

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 our revolving credit facility and our long-term financing.

On August 4, 2014, our subsidiary, WLKP, closed its initial public offering of 12,937,500 common units at a price of $24.00 per unit. We received approximately $230.8 million in net proceeds from the offering as reimbursement for capital expenditures incurred with respect to certain of the assets contributed to OpCo, a subsidiary of WLKP, and for the repayment of intercompany debt.

In May 2014, we announced that we had entered into a definitive agreement to acquire German-based Vinnolit from several entities associated with Advent International Corporation. Vinnolit is an integrated global leader in specialty PVC resins. The purchase price of approximately €490.0 million was financed using existing Westlake cash and credit facilities. This transaction closed on July 31, 2014.

In April 2011, we announced an expansion program to increase the ethane-based ethylene capacity of both of the ethylene units at our Lake Charles complex. We completed the expansion of the first ethylene unit in the first quarter of 2013. We currently plan to upgrade and expand the capacity of the other ethylene unit at our Lake Charles complex in the late 2015 to early 2016 time frame. This project is currently estimated to cost in the range of $250.0 million to $310.0 million and will add approximately 250 million pounds of ethylene capacity. The additional capacity from this expansion is expected to provide ethylene for existing internal uses and may also be sold in the merchant market. This capital project is expected to be funded with cash on hand, cash flow from operations, and, if necessary, borrowings under our revolving credit facility and other external financing. As of June 30, 2014 , we had incurred a total cost of approximately $25.5 million on this capital project.

In August 2011, our Board of Directors authorized a stock repurchase program totaling $100.0 million. As of June 30, 2014 , we had repurchased 1,252,922 shares of our common stock (on a post-split basis) for an aggregate purchase price of approximately $46.2 million under this program. We did not repurchase any shares under this program during the three months ended June 30, 2014 . Purchases under this 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 program will be influenced by our cash on hand, our cash flow from operations, general market conditions and other factors. The program may be discontinued by our Board of Directors at any time.

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 may depend on our ability to obtain additional financing in the future. We may not be able to access additional liquidity at cost effective interest rates due to the volatility of the commercial credit markets.

Cash and Cash Equivalents

As of June 30, 2014 , our cash and cash equivalents totaled $876.1 million . In addition, we have a revolving credit facility available to supplement cash if needed, as described under "Debt" below.

Table of Contents

Debt

As of June 30, 2014 , our long-term debt, including current maturities, totaled $763.9 million , consisting of $250.0 million principal amount of 3.60% senior notes due 2022 (less the unamortized discount of $1.0 million ), $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% GO Zone Senior Notes Due 2035"), $65.0 million of 6 ½% senior notes due 2035 (the "6 ½% IKE Zone Senior Notes Due 2035") (collectively, but excluding the 3.60% senior notes due 2022, the "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). The 6 ½% senior notes due 2029, the 6 ¾% senior notes due 2032, the 6 ½% GO Zone Senior Notes Due 2035 and the 6 ½% IKE Zone Senior Notes Due 2035 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 June 30, 2014 , debt outstanding under the tax-exempt waste disposal revenue bonds bore interest at a variable rate. As of June 30, 2014 , we were in compliance with all of the covenants with respect to the 3.60% senior notes due 2022, the Senior Notes, our waste disposal revenue bonds and our revolving credit facility.

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, we believe our cash flow from operations, available cash and available borrowings under our revolving credit facility will be adequate to meet our normal operating needs for the foreseeable future.

Revolving Credit Facility

We have a $400.0 million senior secured revolving credit facility. At June 30, 2014 , we had no borrowings outstanding under the revolving credit facility.

In July 2014, we entered into a third amendment and restatement to the revolving credit facility. The third amendment and restatement extended the scheduled maturity date of the facility from September 16, 2016 to July 17, 2019, reduced the interest rate and facility fee payable under the facility and amended the covenants restricting our ability to make distributions and acquisitions and make investments, among other things.

The facility includes a provision permitting us to increase the size of the facility, up to four times, in increments of at least $25.0 million each (up to a maximum of $200.0 million) under certain circumstances if certain lenders agree to commit to such an increase.

Any borrowings under the facility will bear interest at either LIBOR plus a spread ranging from 1.75% to 1.25%, provided that so long as we are rated investment grade, the margin for LIBOR loans will not exceed 1.50%, or a base rate plus a spread ranging from 0.50% to 0.00%. The revolving credit facility also requires an unused commitment fee of 0.25% per annum. All interest rates under the facility are subject to monthly grid pricing adjustments based on prior month average daily loan availability. The revolving credit facility matures on July 17, 2019. As of June 30, 2014 , we had outstanding letters of credit totaling $17.8 million and borrowing availability of $382.2 million under the revolving credit facility.

Our revolving credit facility generally restricts our ability to make distributions unless, on a pro forma basis after giving effect to the distribution, the borrowing availability under the facility equals or exceeds the greater of (1) 20% of the commitments under the facility and (2) $80.0 million; or the borrowing availability under the facility equals or exceeds the greater of (1) 15% of the commitments under the facility and (2) $60.0 million, and our fixed charge coverage ratio is at least 1.0:1. However, we may make specified distributions up to an aggregate of $75.0 million, to be increased by 5% in 2015, and in each fiscal year thereafter, on an aggregate basis, for each fiscal year.

In order to make acquisitions or investments, our revolving credit facility provides that (1) we must maintain a minimum borrowing availability of at least the greater of $60.0 million or 15% of the total bank commitments under our revolving credit facility or (2) we must maintain a minimum borrowing availability of at least the greater of $50.0 million or 12.5% of the total bank commitments under our revolving credit facility and meet a minimum fixed charge coverage ratio of 1.0:1 under our revolving credit facility. Notwithstanding the foregoing, we may make investments in the aggregate up to the greater of $50.0 million and 1.25% of tangible assets and acquisitions in the aggregate up to the greater of $100.0 million and 2.5% of tangible assets, if, on a pro forma basis after giving effect to the acquisition or investment, either (1) the borrowing availability under the facility equals or exceeds the greater of (A) 12.5% of the total bank commitments under the facility and (B) $50.0 million, or (2) our fixed charge coverage ratio is at least 1.0:1.

Table of Contents

The revolving credit facility contains other customary covenants and events of default that impose significant operating and financial restrictions on us. These restrictions, among other things, provide limitations on the occurrence of additional indebtedness and our ability to create liens, to engage in certain affiliate transactions and to engage in sale-leaseback transactions. See our Current Report on Form 8-K filed with the SEC on July 17, 2014 for more information on the third amendment and restatement of our revolving credit facility.

GO Zone and IKE Zone Bonds

As of June 30, 2014 , 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% GO Zone Senior Notes Due 2035 and 6 ½% IKE Zone Senior Notes Due 2035. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt" in the 2013 Form 10-K for more information on the 6 ½% senior notes due 2029, the 6 ¾% senior notes due 2032, the 6 ½% GO Zone Senior Notes Due 2035 and the 6 ½% IKE Zone Senior Notes Due 2035. 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 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% of our consolidated net income for the period from October 1, 2003 to the end of the most recent quarter for which financial statements have been filed, plus 100% 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 2013 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 assets.

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.

Off-Balance Sheet Arrangements

None.

We have based these statements on assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe were appropriate in the circumstances when the statements were made. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such statements. These statements are subject to a number of assumptions, risks and uncertainties, including those described in "Risk Factors" in the 2013 Form 10-K and the following:


•	general economic and business conditions;

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 June 30, 2014 , a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before taxes by $11.3 million and a hypothetical $0.10 increase in the price of a pound of ethylene would have decreased our income before taxes by $6.0 million . Additional information concerning derivative commodity instruments appears in Notes 9 and 10 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 June 30, 2014 , we had variable rate debt of $10.9 million outstanding. All of the debt outstanding under our revolving credit facility (none was outstanding at June 30, 2014 ) and our loan relating to the tax-exempt waste disposal revenue bonds are at variable rates. 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 June 30, 2014 was 0.07%. 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 June 30, 2014 , we had $754.0 million aggregate principal amount of fixed rate debt. We are subject to the risk of higher interest cost if and when this debt is refinanced. If interest rates are 1% higher at the time of refinancing, our annual interest expense would increase by approximately $7.5 million.


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 Senior Vice President, Chief Financial Officer and Treasurer, 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 Senior Vice President, Chief Financial Officer and Treasurer concluded that our disclosure controls and procedures are effective with respect to (i) the accumulation and communication to our management, including our Chief Executive Officer and our Chief Financial Officer, of information required to be disclosed by us in the reports that we submit under the Exchange Act, and (ii) the recording, processing, summarizing and reporting of such information within the time periods specified in the SEC's rules and forms.

There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION



Item 1.	Legal Proceedings

The 2013 Form 10-K, filed on February 21, 2014, contained a description of various legal proceedings in which we are involved, including environmental proceedings at our facilities in Calvert City. See Note 15 to the unaudited consolidated financial statements within this Quarterly Report on Form 10-Q for a description of certain of those proceedings, which information is incorporated by reference herein.



Item 1A.	Risk Factors

For a discussion of risk factors, please read Item 1A, "Risk Factors" in the 2013 Form 10-K. There have been no material changes from those risk factors, except as described below.

We may have difficulties integrating the operations of Vinnolit.

If we are unable to integrate or to successfully manage the Vinnolit operations, our business, financial condition, results of operations and cash flows could be adversely affected. We may not be able to realize the operating efficiencies, synergies, cost savings or other benefits expected from the acquisition for a number of reasons, including, but not limited to, the following: (i) we may fail to integrate the business into a cohesive, efficient enterprise; (ii) our resources, including management resources, are limited and may be strained, and the acquisition may divert our management's attention from initiating or carrying out programs to save costs or enhance revenues; and (iii) our failure to retain key employees and contracts of the business.
