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 have not been included. These interim consolidated financial statements should be read in conjunction with the December 31, 2010 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, 2010, filed with the SEC on February 24, 2011. 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, 2010.

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, 2011, its results of operations for the three and nine months ended September 30, 2011 and 2010 and the changes in its cash position for the nine months ended September 30, 2011 and 2010.

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 year ending December 31, 2011 or any other interim period. The preparation of financial statements in conformity with generally accepted accounting principles in the United States 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

Fair Value Measurement

In January 2010, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update on fair value measurement disclosures. The new accounting guidance requires disclosures on significant transfers in and out of Levels 1 and 2 of the fair value hierarchy and gross presentation of Level 3 reconciliation components. It also clarifies two existing disclosure requirements regarding fair value disclosures by class of assets and liabilities rather than by major category and disclosures of valuation technique and the inputs used in determining fair value of each class of assets and liabilities for Levels 2 and 3 measurements. The accounting standards update is effective for reporting periods beginning after December 15, 2009, except for the gross presentation of the Level 3 reconciliation, which is effective for reporting periods beginning after December 15, 2010. With the exception of the gross presentation of the Level 3 reconciliation, the Company adopted the guidance as of January 1, 2010, and it did not have an impact on the Company’s consolidated financial position or results of operations. The Company adopted the guidance pertaining to the gross presentation of the Level 3 reconciliation as of January 1, 2011, and the adoption did not have an impact on the Company’s consolidated financial position or results of operations.

In May 2011, the FASB issued new accounting guidance changing some fair value measurement principles, such as by prohibiting the application of a blockage factor in fair value measurements and only requiring the application of the highest and best use concept when measuring nonfinancial assets. The accounting guidance will require, for recurring Level 3 fair value measurements, disclosure of quantitative information about unobservable inputs used, a description of the valuation processes used and a qualitative discussion about the sensitivity of the measurements. The accounting guidance further requires new disclosures about the use of a nonfinancial asset measured or disclosed at fair value if its use differs from its highest and best use. In addition, entities must report the fair value hierarchy level of assets and liabilities not recorded at fair value but where fair value is disclosed. The accounting standards update will be effective for reporting periods beginning after December 15, 2011 and is not expected to have a material impact on the Company’s consolidated financial position or results of operations.

Presentation of Other Comprehensive Income

In June 2011, the FASB issued an accounting standards update on the presentation of other comprehensive income. The new accounting guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in stockholders’ equity. The new standard allows companies to present net income and other comprehensive income either in one continuous statement or in two separate, but consecutive, statements. The accounting standards update will be effective for fiscal years beginning after December 15, 2011 and is not expected to have an impact on the Company’s consolidated financial position or results of operations.

Testing Goodwill for Impairment

In September 2011, the FASB issued an accounting standards update to simplify how entities test goodwill for impairment. The new accounting guidance provides an entity with an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test under current accounting guidance. If an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test. Also under this new accounting guidance, an entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test, but may resume performing the qualitative assessment in any subsequent period. The accounting standards update will be effective for reporting periods beginning after December 15, 2011 and is not expected to have a material impact on the Company’s consolidated financial position or results of operations.

2. Accounts Receivable

Accounts receivable consist of the following:


	September 30, 2011			December 31, 2010
Trade customers	$	442,622		$	353,035

Federal and state taxes		21,903			15,499
Other		8,274			3,564

Accounts receivable, net	$	462,470		$	362,863

3. Inventories

	September 30, 2011		December 31, 2010
Finished products	$	241,703	$	219,568
Feedstock, additives and chemicals		180,270		189,007
Materials and supplies		44,275		41,453

Inventories	$	466,248	$	450,028

4. Property, Plant and Equipment

As of September 30, 2011, the Company had property, plant and equipment totaling $1,195,508. 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 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.

In June 2011, as a result of excess capacity in the PVC pipe market and in an effort to reduce costs and optimize operations, the Company closed its Springfield, Kentucky PVC pipe facility. Asset impairment costs and severance and other costs related to the PVC pipe facility closure recorded during the nine months ended September 30, 2011 were $1,975 and $1,389, respectively. The Company determined the fair value of the impaired assets using internally developed, unobservable inputs (Level 3 inputs in the fair value hierarchy of fair value accounting) based on the projected cash flows of the pipe facility.

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

Depreciation expense on property, plant and equipment of $27,623 and $26,433 is included in cost of sales in the consolidated statements of operations for the three months ended September 30, 2011 and 2010, respectively. Depreciation expense on property, plant and equipment of $82,423 and $78,989 is included for the nine months ended September 30, 2011 and 2010, respectively.

5. Other Assets

Investments reflected in other assets, net in the consolidated balance sheet at September 30, 2011 were $21,218. These investments have been classified as available-for-sale.

The cost, gross unrealized losses and fair value of the investments were as follows:


	September 30, 2011
	Cost		Gross Unrealized Losses ⁽¹⁾			Fair Value
Available-for-sale investments	$	27,877	$	(6,659	)	$	21,218

(1)	All unrealized loss positions were held at a loss for less than 12 months.

Because the Company does not intend to sell, nor is it likely to be forced to sell, its available-for-sale investments, declines in fair value are mostly considered temporary. The Company regularly evaluates available evidence to determine if its investments are other-than-temporarily impaired. The Company considers the evidence to support the recovery of the cost basis of investments, the length of time the investments are in a loss position, value and growth expectations and overall market and sector fundamentals, in determining whether unrealized losses represent an other-than-temporary impairment.

See Note 9 for the fair value hierarchy of the Company’s available-for-sale investments.

Amortization expense on other assets of $5,664 and $6,728 is included in the consolidated statements of operations for the three months ended September 30, 2011 and 2010, respectively. Amortization expense on other assets of $17,110 and $19,081 is included for the nine months ended September 30, 2011 and 2010, respectively.

6. Long-Term Debt

Long-term debt consists of the following:


	September 30, 2011		December 31, 2010
6 ⁵/8% senior notes due 2016	$	249,654	$	249,593

Long-term debt	$	764,543	$	764,482

The Company has a $400,000 senior secured revolving credit facility. In September 2011, the Company entered into a second amendment and restatement to the revolving credit facility. The amendment and restatement extended the scheduled maturity date of the facility from September 8, 2013 to September 16, 2016, reduced the interest rate and facility fee payable under the facility, amended the covenants restricting the Company’s ability to make distributions and acquisitions and make investments and, among other things:

•

includes a covenant requiring the Company to maintain a minimum fixed charge coverage ratio of 1.0:1 for successive 30-day periods after any date on which the borrowing availability under the facility is less than the greater of (1) 12.5% of the commitments under the facility and (2) $50,000, until the borrowing availability exceeds the greater of the amount in clause (1) and the amount in clause (2) for a 30-day period;

•

generally allows the Company to incur up to $150,000 in purchase money debt and eliminates a $20,000 maximum limit on the amount of capital leases that it may enter into;

WESTLAKE CHEMICAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(Unaudited)

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

•

generally allows the Company to incur an amount of debt secured by liens on its assets that are not collateral under the facility up to the greater of (1) $600,000 and (2) 30% of tangible assets;

•

generally allows the Company to enter into sale and leaseback transactions in an amount up to an aggregate of $150,000; and

•

so long as no default or event of default has occurred or is continuing, allows the Company to prepay any debt with unrestricted cash and to prepay any of its existing senior notes with unrestricted or restricted cash.

The facility also 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 certain lenders agree to commit to such an increase.

Amounts drawn under the facility are limited to (1) 85% of the net amount of eligible accounts receivable, plus (2) the lesser of (a) 70% of the value of the lower of cost or market of eligible inventory, or (b) 85% of the appraised net orderly liquidation value of all eligible inventory, plus (3) 100% of cash held in an account with Bank of America and subject to a control agreement with Bank of America, minus (4) such reserves as Bank of America, the agent, may establish. Advances on inventory are limited to $325,000. The facility includes a $400,000 sub-limit for letters of credit, and any outstanding letters of credit will be deducted from availability under the facility.

At September 30, 2011, 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 September 30, 2011, the Company had outstanding letters of credit totaling $17,662 and borrowing availability of $382,338 under the revolving credit facility.

7. Stock-Based Compensation

Under the Westlake Chemical Corporation 2004 Omnibus Incentive Plan (the “2004 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 2004 Plan. At the discretion of the administrator of the 2004 Plan, employees and nonemployee directors may be granted awards in the form of stock options, stock appreciation rights, stock awards or cash awards (any of which may be a performance award). Total stock-based compensation expense related to the 2004 Plan was $1,636 and $1,587 for the three months ended September 30, 2011 and 2010, respectively, and $4,762 and $4,566 for the nine months ended September 30, 2011 and 2010, respectively.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the quarter and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2011. This amount changes based on the fair market value of the Company’s common stock. The total intrinsic value of options exercised was $355 for the three months ended September 30, 2010, and $8,147 and $758 for the nine months ended September 30, 2011 and 2010, respectively. There were no options exercised during the three months ended September 30, 2011.

As of September 30, 2011, $3,636 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.3 years. Income tax benefit realized from the exercise of stock options was $44 for the three months ended September 30, 2010, and $2,148 and $135 for the nine months ended September 30, 2011 and 2010, respectively.

The Company uses the Black-Scholes option pricing model to value its options. The table below presents the weighted average value and assumptions used in determining the fair value for each option granted during the nine months ended September 30, 2011 and 2010. There were no options granted during the three months ended September 30, 2011 and 2010. Volatility was calculated using historical trends of the Company’s common stock price.

As of September 30, 2011, there was $5,721 of unrecognized stock-based compensation expense related to non-vested restricted stock awards. This cost is expected to be recognized over a weighted-average period of 1.3 years. The total fair value of shares of restricted stock that vested was $374 and $168 for the three months ended September 30, 2011 and 2010, respectively. The total fair value of shares of restricted stock that vested was $6,214 and $1,354 for the nine months ended September 30, 2011 and 2010, respectively.

8. Derivative Commodity Instruments

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 nine months ended September 30, 2011. As of September 30, 2011, the Company had 34,650,000 gallons of feedstock forward contracts designated as fair value hedges.

Gains and losses from changes in the fair value of derivative instruments that are not designated as hedging instruments were included in cost of sales in the consolidated statements of operations for the three and nine months ended September 30, 2011 and 2010.

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


	Asset Derivatives						Liability Derivatives
			Fair Value as of						Fair Value as of
	Balance Sheet Location		September 30, 2011		December 31, 2010		Balance Sheet Location		September 30, 2011		December 31, 2010

Total derivatives			$	3,194	$	47			$	3,506	$	46

The following tables reflect the impact of derivative instruments designated as fair value hedges and the related hedged item on the Company’s consolidated statements of operations. For the three and nine months ended September 30, 2011, there was no material ineffectiveness with regard to the Company’s qualifying hedges.

9. Fair Value Measurements

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

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

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

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:


	September 30, 2011
	Level 1		Level 2			Total

The Level 2 measurements are derived using forward curves supplied by industry recognized and unrelated third-party services. There were no transfers in and out of Levels 1 and 2 of the fair value hierarchy for the nine months ended September 30, 2011 and 2010.

In addition to the financial instruments 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 carrying 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 below:


	September 30, 2011				December 31, 2010
	Carrying Value		Fair Value		Carrying Value		Fair Value
6⁵/8% senior notes due 2016	$	249,654	$	256,875	$	249,593	$	258,438

Variable rate tax-exempt waste disposal revenue bonds due 2027		10,889		10,889		10,889		10,889

10. Income Taxes

The effective income tax rate was 35.8% for the nine months ended September 30, 2011. The effective income tax rate for the 2011 period was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction. The effective income tax rate was 35.9% for the nine months ended September 30, 2010. The effective income tax rate for the 2010 period was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by state tax credits and the domestic manufacturing deduction.

Management anticipates no material reductions to the total amount of unrecognized tax benefits within the next twelve months.

The Company recognizes penalties and interest accrued related to unrecognized tax benefits in income tax expense. As of September 30, 2011, 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 2005. During the first quarter of 2011, the Internal Revenue Service began an audit of the Company for the 2009 tax year, and such audit continued during the third quarter of 2011.

11. Earnings per Share

The Company has non-vested shares of restricted stock that are considered participating securities and 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.

		00,000			00,000			00,000			00,000

Diluted	$	1.01	$	0.95	$	3.48	$	2.07

Excluded from the computation of diluted earnings per share are options to purchase 99,592 and 698,340 shares of common stock for the three months ended September 30, 2011 and 2010, respectively, and 151,923 and 699,710 shares of common stock for the nine months ended September 30, 2011 and 2010, respectively. These options were outstanding during the periods reported but were excluded because the effect of including them would have been antidilutive.

The Company expects to make additional contributions of $442 to the Salaried pension plan and $524 to the Wage pension plan during the fiscal year ending December 31, 2011.

14. 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, 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 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 PVC facility, had been extensively contaminated by 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 Calvert City complex do not have a specified termination date but are expected to last for the foreseeable future. The costs incurred by PolyOne to provide the environmental remediation services were $3,028 in 2010. On March 17, 2010, the Company received notice of PolyOne’s intention to commence 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.

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 pursuant to an Administrative Settlement Agreement (“AOC”), which became effective on December 9, 2009. See “Change in Regulatory Regime” below. The proceedings have been postponed. Periodic status conferences will be held to evaluate whether additional proceedings will be required. On September 19, 2011, the Company filed a motion to dismiss the remaining proceedings.

Change in Regulatory Regime. In May 2009, the Cabinet sent a letter to the U.S. Environmental Protection Agency (“EPA”) requesting the EPA’s assistance in addressing contamination at the Calvert City site under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (“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 two 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. The parties submitted and received EPA approval for a RIFS work plan to implement the AOC. The parties are conducting the RIFS.

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 in 2011 and later years 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.

EPA Audit of Ethylene Units in Lake Charles. During 2007, the EPA conducted an audit of the Company’s ethylene units in Lake Charles, Louisiana, with a focus on leak detection and repair, or LDAR. In January 2008, the U.S. Department of Justice, or DOJ, notified the Company that the EPA had referred the matter to the DOJ to bring a civil case against the Company alleging violations of various environmental laws and regulations. The DOJ informed the Company that it would seek monetary penalties and require the Company to implement an “enhanced LDAR” program for the ethylene units. The EPA has proposed a settlement and provided a draft consent decree, which would require the Company’s Lake Charles facilities to undertake an enhanced LDAR program and would require payment of a civil penalty. The Company is engaged in negotiations with the EPA. The Company has recorded an accrual for a probable loss related to monetary penalties. Although the ultimate amount of liability is not ascertainable, the Company believes that the resolution of this matter will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

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.

In the first quarter of 2011, in order to better reflect large buyer market related pricing, the Company changed its intersegment market pricing methodology used to account for intersegment sales of ethylene sold from the Olefins segment to the Vinyls segment. Had this pricing methodology been in effect on January 1, 2010, the impact on Olefins segment income from operations for the three and nine months ended September 30, 2010 would be a reduction of $5,948 and $23,642, respectively. These reductions would be offset by an improvement in the Vinyls segment’s operating results for the three and nine months ended September 30, 2010 of $4,560 and $19,697, respectively, and an improvement in the Corporate segment’s operating results for the three and nine months ended September 30, 2010 of $1,388 and $3,945, respectively. The improvement in the Corporate segment’s loss from operations is attributable to a reduction in intercompany profit in inventory reserve related to sales from the Olefins segment to the Vinyls segment. There would be no impact on the Company’s reported consolidated income from operations for the three and nine months ended September 30, 2010.

A reconciliation of total segment income from operations to consolidated income before income taxes is as follows:

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, 2010 (the “2010 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 petrochemicals, polymers and fabricated building products. Our two principal business segments are Olefins and Vinyls. We use the majority of our internally-produced basic chemicals to produce higher value-added chemicals and building products.

In 2009 and continuing through the third quarter of 2011, a cost advantage for natural gas-based ethylene producers over naphtha-based ethylene producers, as well as increased global demand for polyethylene, allowed a strong export market and higher margins for North American producers, including Westlake. However, some olefins industry consultants predict that significant increases in worldwide ethylene and ethylene derivative capacity, which have existed over the past three years, primarily in the Middle East and Asia, will continue for the next several years. As a result, our Olefins segment operating margins may be negatively impacted.

Weakness in the U.S. construction markets, which began in the third quarter of 2006, and the subsequent budgetary constraints in municipal spending, have contributed to lower domestic demand for our vinyls products. In addition, increases in feedstock costs, combined with the industry’s inability to sufficiently raise domestic prices for PVC resin and building products in order to offset cost increases, significantly impacted our Vinyls segment’s operating results in 2010 through the third quarter of 2011. Over the last 12 months, the industry experienced an increase in PVC export demand, driven largely by more competitive ethylene and energy cost positions in North America. As a consequence, domestic PVC resin operating rates improved while domestic supply of PVC resin tightened, resulting in improved margins and higher domestic prices for PVC resin. Looking forward, our Vinyls operating rates and margins may continue to be negatively impacted by the slow recovery of U.S. construction markets and recent North American PVC capacity additions.

While the economic environment continues to be challenging for our customers, we believe our customer base remains generally healthy. As we continue to manage our business in this environment, including the slowdown in construction activity, we have taken steps designed to address the changes in demand and margins in our Vinyls segment and its resulting impact on our operations by matching production with sales demand and continuing to operate our plants in an efficient manner. We continue to monitor our cost management programs and discretionary capital spending. The impact of the global economic environment has been challenging to our business and, depending on the performance of the economy in the remainder of 2011 and beyond, could have a negative effect on our financial condition, results of operations or cash flows.

Recent Developments

In August 2011, our Board of Directors authorized a stock repurchase program totaling $100.0 million. 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. During the third quarter of 2011, we repurchased 54,654 shares of common stock for an aggregate purchase price of $2.0 million.

Summary

For the quarter ended September 30, 2011, net income was $67.9 million, or $1.01 per diluted share, on net sales of $968.4 million. This represents an increase in net income of $5.2 million, or $0.06 per diluted share, from the quarter ended September 30, 2010 net income of $62.7 million, or $0.95 per diluted share, on net sales of $779.7 million. Net sales for the third quarter of 2011 increased $188.7 million compared to net sales for the third quarter of 2010, driven mainly by higher sales prices for all our major products, partially offset by lower building products sales volume. Income from operations was $117.3 million for the third quarter of 2011 as compared to $107.3 million for the third quarter of 2010. Income from operations benefited primarily from higher PVC resin, PVC pipe and caustic margins, partially offset by lower olefins integrated product margins.

For the nine months ended September 30, 2011, net income was $232.5 million, or $3.48 per diluted share, on net sales of $2,760.7 million. This represents an increase in net income of $95.2 million, or $1.41 per diluted share, from the nine months ended September 30, 2010 net income of $137.3 million, or $2.07 per diluted share, on net sales of $2,376.4 million. Net sales for the nine months ended September 30, 2011 increased $384.3 million compared to the first nine months of 2010 mainly due to higher sales prices for all our major products and higher sales volume for PVC resin, partially offset by lower building products sales volume. Income from operations was $396.3 million for the nine months ended September 30, 2011 as compared to $241.3 million for the nine months ended September 30, 2010. Income from operations for the nine months ended September 30, 2011 benefited primarily from improved olefins integrated product margins, higher PVC resin and PVC pipe sales prices, higher PVC resin sales volume and improved caustic margins as compared to the prior year period, partially offset by higher feedstock costs. The nine months ended September 30, 2011 were negatively impacted by the lost production, lost sales and higher operating costs associated with four separate events: an unscheduled outage at one of our ethylene units in Lake Charles, Louisiana, the turnaround of our Calvert City, Kentucky facility, a fire at a third-party storage facility in Mont Belvieu, Texas and the closure of our Springfield, Kentucky PVC pipe production facility. Trading activity for the nine months ended September 30, 2011 resulted in a gain of $0.8 million compared to a loss of $1.6 million for the nine months ended September 30, 2010. Income from operations for the nine months ended September 30, 2010 was negatively impacted by an unscheduled outage at one of our ethylene units in Lake Charles caused by freezing temperatures.

RESULTS OF OPERATIONS

Third Quarter 2011 Compared with Third Quarter 2010

Net Sales. Net sales increased by $188.7 million, or 24.2%, to $968.4 million in the third quarter of 2011 from $779.7 million in the third quarter of 2010. This increase was primarily due to higher sales prices for all our major products as compared to the prior year period. Average sales prices for the third quarter of 2011 increased by 28.6% as compared to the third quarter of 2010. Overall sales volume decreased by 4.8% as compared to the third quarter of 2010, primarily caused by lower building products sales volume attributable to weakness in the U.S. construction markets.

Gross Margin. Gross margin percentage decreased to 15.2% for the third quarter of 2011 from 17.3% for the third quarter of 2010. The third quarter 2011 gross margin benefited from improved PVC resin, PVC pipe and caustic margins. However, this increase was more than offset by lower operating rates, lower sales volumes for several major products and feedstock cost increases that outpaced price increases in our Olefins segment. Our raw material cost in both segments normally tracks industry prices, which experienced an increase of 62.3% and 43.9% for ethane and propane, respectively, as compared to the third quarter of 2010. Sales prices increased an average of 28.6% for the third quarter of 2011 as compared to the third quarter of 2010.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the third quarter of 2011 increased by $2.2 million as compared to the third quarter of 2010 primarily attributable to an increase in payroll and related labor costs, including incentive compensation, and consulting fees.

Interest Expense. Interest expense increased by $1.7 million to $12.7 million in the third quarter of 2011 as compared to the prior year period, primarily due to higher average debt outstanding for the period as a result of the issuance of our senior notes in December 2010.

Other Income, Net. Other income, net increased to $1.5 million in the third quarter of 2011 from $0.6 million in the third quarter of 2010, mainly attributable to higher equity in income from our joint ventures and higher interest income, partially offset by foreign exchange currency losses.

Income Taxes. The effective income tax rate was 36.0% for the third quarter of 2011. The effective income tax rate for the third quarter of 2011 was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction. The effective income tax rate was 35.3% for the third quarter of 2010. The effective income tax rate for the third quarter of 2010 was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by state tax credits and the domestic manufacturing deduction.

Olefins Segment

Net Sales. Net sales increased by $140.5 million, or 25.3%, to $695.7 million in the third quarter of 2011 from $555.2 million in the third quarter of 2010. This increase was primarily due to an increase in sales prices for all major products, partially offset by lower polyethylene sales volume as compared to the prior year period. Average sales prices for the Olefins segment increased by 27.0% in the third quarter of 2011 as compared to the third quarter of 2010. Average sales volumes decreased by 2.3% in the third quarter of 2011 as compared to the third quarter of 2010.

Income from Operations. Income from operations decreased by $30.7 million, or 22.6%, to $105.4 million in the third quarter of 2011 from $136.1 million in the third quarter of 2010. This decrease was mainly attributable to higher feedstock costs that outpaced sales price increases, lower polyethylene sales volume and lower operating rates. The lower operating rates were primarily due to reduced polyethylene export demand. Trading activity resulted in a gain of $0.4 million in the third quarter of 2011 as compared to a gain of $0.5 million in the third quarter of 2010.

Vinyls Segment

Net Sales. Net sales increased by $48.2 million, or 21.5%, to $272.7 million in the third quarter of 2011 from $224.5 million in the third quarter of 2010. This increase was primarily driven by higher sales prices for all major products and higher PVC resin sales volume, partially offset by lower building products sales volume as compared to the third quarter of 2010. Average sales prices for the Vinyls segment increased by 32.7% in the third quarter of 2011 as compared to the third quarter of 2010. Average sales volumes for the Vinyls segment decreased by 11.3% in the third quarter of 2011 as compared to the third quarter of 2010, primarily caused by lower building products sales volume attributable to weakness in the U.S. construction markets.

Income (Loss) from Operations. Income from operations was $16.1 million in the third quarter of 2011 as compared to a loss from operations of $24.2 million in the third quarter of 2010, an improvement of $40.3 million. This improvement was primarily due to improved PVC resin, PVC pipe and caustic margins, and higher PVC resin sales volume as compared to the prior year period. PVC resin and PVC pipe margins benefited from an increase in product prices driven mainly by strong PVC resin export demand. While operating results for the third quarter of 2011 improved compared to the third quarter of 2010, our Vinyls segment continued to be negatively impacted by weakness in the U.S. construction markets.

Nine Months Ended September 30, 2011 Compared with Nine Months Ended September 30, 2010

Net Sales. Net sales increased by $384.3 million, or 16.2%, to $2,760.7 million for the first nine months of 2011 from $2,376.4 million for the first nine months of 2010. This increase was primarily due to higher sales prices for all major products and higher sales volume for PVC resin, partially offset by lower building products sales volume as compared to the prior year period. Average sales prices for the first nine months of 2011 increased by 20.4% as compared to the first nine months of 2010. Overall sales volume decreased by 4.3% as compared to the first nine months of 2010.

Gross Margin. Gross margin percentage of 17.4% for the nine months ended September 30, 2011 increased from the 13.4% gross margin percentage for the nine months ended September 30, 2010. The increase was primarily due to improved olefins integrated product margins, higher PVC resin, PVC pipe and caustic sales prices and higher PVC resin sales volume as compared to the prior year period, partially offset by higher feedstock costs, the unscheduled Lake Charles outage, the Calvert City turnaround, the closure of our Springfield PVC pipe facility and the fire at a third-party storage facility in Mont Belvieu.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the nine months ended September 30, 2011 increased by $8.2 million as compared to the nine months ended September 30, 2010. The increase was mainly attributable to an increase in payroll and related labor costs, including incentive compensation, partially offset by a decrease in legal fees.

Interest Expense. Interest expense increased by $9.8 million to $38.4 million in the first nine months of 2011 as compared to the first nine months of 2010, primarily due to higher average debt outstanding for the period as a result of the issuance of our senior notes in July and December 2010.

Other Income, Net. Other income, net increased to $4.3 million in the first nine months of 2011 from $1.5 million in the first nine months of 2010, mainly due to higher equity in income from our joint ventures and higher interest income, partially offset by foreign exchange currency losses.

Income Taxes. The effective income tax rate was 35.8% for the nine months ended September 30, 2011. The effective income tax rate for the 2011 period was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by the domestic manufacturing deduction. The effective income tax rate was 35.9% for the nine months ended September 30, 2010. The effective income tax rate for the 2010 period was above the statutory rate of 35.0% primarily due to state income taxes, partially offset by state tax credits and the domestic manufacturing deduction.

Olefins Segment

Net Sales. Net sales increased by $248.6 million, or 14.6%, to $1,946.1 million for the nine months ended September 30, 2011 from $1,697.5 million for the nine months ended September 30, 2010. This increase was primarily due to an increase in sales prices for all major products, partially offset by lower ethylene and polyethylene sales volumes. Average sales prices for the Olefins segment increased by 19.5% in the first nine months of 2011 as compared to the first nine months of 2010. Average sales volumes decreased by 5.0% in the first nine months of 2011 as compared to the first nine months of 2010.

Income from Operations. Income from operations increased by $77.9 million, or 25.5%, to $383.4 million in the first nine months of 2011 from $305.5 million in the first nine months of 2010. This increase was mainly attributable to higher polyethylene sales prices, which were only partially offset by higher feedstock costs as compared to the prior year period. The nine months ended September 30, 2011 were negatively impacted by the unscheduled outage at one of our ethylene units in Lake Charles and the fire at a third-party storage facility at Mont Belvieu. Trading activity resulted in a gain of $0.8 million for the nine months ended September 30, 2011 as compared to a loss of $1.6 million for the prior year period. The first nine months of 2010 were negatively impacted by the unscheduled outage at one of our ethylene units in Lake Charles caused by freezing temperatures.

Vinyls Segment

Net Sales. Net sales increased by $135.7 million, or 20.0%, to $814.6 million for the nine months ended September 30, 2011 from $678.9 million for the nine months ended September 30, 2010. This increase was primarily driven by higher sales prices for all major products and an increase in sales volume for PVC resin, partially offset by lower building products sales volume as compared to the prior year period. Average sales prices for the Vinyls segment increased by 22.5% in the first nine months of 2011 as compared to the first nine months of 2010. Average sales volumes decreased by 2.5% in the first nine months of 2011 as compared to the first nine months of 2010.

Income (Loss) from Operations. Income from operations improved by $73.6 million to $23.6 million for the nine months ended September 30, 2011 as compared to a loss from operations of $50.0 million for the nine months ended September 30, 2010. This improvement was primarily attributable to improved PVC resin, PVC pipe and caustic margins and higher PVC resin sales volume as compared to the prior year period. PVC resin sales volume and product pricing during the nine months ended September 30, 2011 benefited from a strong export market. The improvement in operating results was partially offset by the negative impact of the turnaround at our Calvert City facility and the closure of our Springfield PVC pipe facility. The Vinyls segment’s operating results for the first nine months of 2010 were negatively impacted by lower margins for caustic attributable to a significant decline in industry caustic prices.

CASH FLOW DISCUSSION FOR NINE MONTHS ENDED SEPTEMBER 30, 2011 AND 2010

Cash Flows

Operating Activities

Operating activities provided cash of $244.4 million in the first nine months of 2011 compared to cash provided of $215.0 million in the first nine months of 2010. The $29.4 million increase in cash flows from operating activities was primarily due to an increase in income from operations in the first nine months of 2011 compared to the prior year period, partially offset by increases in working capital and income taxes paid. Income from operations increased by $155.0 million in the first nine months of 2011 as compared to the first nine months of 2010 mainly as a result of higher olefins integrated product margins, higher PVC resin and PVC pipe sales prices, higher PVC resin sales volume and improved caustic margins, partially offset by higher feedstock costs. Changes in components of working capital, which we define for purposes of this cash flow discussion as accounts receivable, inventories, prepaid expense and other current assets less accounts payable and accrued liabilities, used cash of $108.0 million in the first nine months of 2011, compared to $37.7 million of cash used in the first nine months of 2010, an unfavorable change of $70.3 million. This change was largely due to an increase in accounts receivable primarily driven by the increase in average product prices as compared to the prior year period.

Investing Activities

Net cash used for investing activities during the first nine months of 2011 was $138.8 million as compared to net cash used for investing activities of $42.9 million in the first nine months of 2010. Capital expenditures were $111.8 million in the first nine months of 2011 compared to $51.2 million in the first nine months of 2010. The higher capital expenditures in the 2011 period were largely attributable to expenditures related to capital projects to improve production capacity or reduce costs at our various facilities. The remaining capital expenditures in the first nine months of 2011 and 2010 primarily related to maintenance, safety and environmental projects. Purchases of investments during the first nine months of 2011 totaled $29.9 million. We received proceeds of $7.1 million for the settlement of derivative instruments during the first nine months of 2010.

Financing Activities

Net cash provided by financing activities during the first nine months of 2011 was $23.1 million as compared to net cash provided of $10.7 million in the first nine months of 2010. The 2011 period activity was primarily related to a $33.7 million draw-down of our restricted cash for use for eligible capital expenditures and proceeds of $5.3 million from the exercise of stock options. Net cash provided by financing activities was partially offset by the $13.4 million payment of cash dividends. The 2010 period activity was primarily related to a $22.6 million draw-down of our restricted cash, partially offset by the payment of cash dividends.

Liquidity and Capital Resources

Liquidity and Financing Arrangements

Our principal sources of liquidity are from cash and cash equivalents, restricted cash, cash from operations, short-term borrowings under our revolving credit facility and our long-term financing. As we continue to manage our business through the current economic environment, we have maintained our focus on cost control and various initiatives designed to preserve cash and liquidity.

In August 2011, our Board of Directors authorized a stock repurchase program totaling $100.0 million. As of September 30, 2011, we had repurchased 54,654 shares of common stock for an aggregate purchase price of $2.0 million under this program. 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.

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 currently expect to complete the expansion of one of the two ethylene units by late 2012. This expansion is currently estimated to cost in the range of $110.0 million to $145.0 million. The additional capacity from this expansion is expected to provide ethylene for existing internal derivatives units and the merchant market. In August 2010, we announced that we intend to proceed with the previously announced plans for the construction of a new chlor-alkali plant at our Geismar, Louisiana facility. The project is estimated to cost in the range of $250.0 million to $300.0 million and is targeted for start-up in the second half of 2013. These projects would be funded with cash on hand, cash flow from operations, the net proceeds from certain of the revenue bonds of the Louisiana Local Government Environmental Facility and Development Authority (the “Authority”), a political subdivision of the State of Louisiana, which are currently held as restricted cash, and if necessary, our revolving credit facility and other external financing.

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 of third-party assets 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 Restricted Cash

Total cash balances were $875.6 million at September 30, 2011, which included cash and cash equivalents of $758.9 million and restricted cash of $116.7 million. The restricted cash is held by a trustee until such time as we request reimbursement of amounts used to expand, refurbish and maintain our facilities in the Calcasieu and Ascension Parishes of Louisiana. In addition, we have a revolving credit facility available to supplement cash if needed, as described under “Debt” below.

Debt

As of September 30, 2011, our long-term debt, including current maturities, totaled $764.5 million, consisting of $250.0 million principal amount of 6 ⁵/8% senior notes due 2016 (less the unamortized discount of $0.4 million), $100.0 million of 6 ¹/2% senior notes due 2029, $250.0 million of 6 ³/4% senior notes due 2032, $89.0 million of 6 ¹/2% senior notes due 2035 (the “2035 GO Zone 6 ¹/2% Notes”), $65.0 million of 6 ¹/2% senior notes due 2035 (the “2035 IKE Zone 6 ¹/2% Notes”) (collectively, 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 ¹/2% senior notes due 2029, the 6 ³/4% senior notes due 2032, the 2035 GO Zone 6 ¹/2% Notes and the 2035 IKE Zone 6 ¹/2% Notes

evidence and secure our obligations to the Authority 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, 2011, debt outstanding under the tax-exempt waste disposal revenue bonds bore interest at a variable rate. As of September 30, 2011, we were in compliance with all of the covenants with respect to our Senior Notes, our waste disposal revenue bonds and our revolving credit facility.

As of September 30, 2011, we had drawn $234.5 million of the proceeds from the issuance of the 6 ³/4% senior notes due 2032, $37.6 million of the proceeds from the issuance of the 2035 GO Zone 6 ¹/2% Notes and $15.2 million of the proceeds from the issuance of the 2035 IKE Zone 6 ¹/2% Notes. The balance of the proceeds, plus interest income, remains with the trustee, and is classified on our consolidated balance sheet as a non-current asset, restricted cash, until such time as we request reimbursement of amounts used to expand, refurbish and maintain certain of our facilities in Louisiana. We had drawn all the proceeds from the issuance of the 6 ¹/2% senior notes due 2029 as of December 31, 2010. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt” in the 2010 Form 10-K for more information on the 6 ¹/2% senior notes due 2029, the 6 ³/4% senior notes due 2032, the 2035 GO Zone 6 ¹/2% Notes and the 2035 IKE Zone 6 ¹/2% 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.

We have a $400.0 million senior secured revolving credit facility. In September 2011, we entered into a second amendment and restatement to the revolving credit facility. The amendment and restatement extended the scheduled maturity date of the facility from September 8, 2013 to September 16, 2016, reduced the interest rate and facility fee payable under the facility, amended the covenants restricting our ability to make distributions and acquisitions and make investments and, among other things:

•

includes a covenant requiring us to maintain a minimum fixed charge coverage ratio of 1.0:1 for successive 30-day periods after any date on which the borrowing availability under the facility is less than the greater of (1) 12.5% of the commitments under the facility and (2) $50.0 million, until the borrowing availability exceeds the greater of the amount in clause (1) and the amount in clause (2) for a 30-day period;

•

generally allows us to incur up to $150.0 million in purchase money debt and eliminates a $20.0 million maximum limit on the amount of capital leases that we may enter into;

•

generally allows us to incur an amount of debt secured by liens on our assets that are not collateral under the facility up to the greater of (1) $600.0 million and (2) 30% of tangible assets;

•

generally allows us to enter into sale and leaseback transactions in an amount up to an aggregate of $150.0 million; and

•

so long as no default or event of default has occurred or is continuing, allows us to prepay any debt with unrestricted cash and to prepay any of our existing senior notes with unrestricted or restricted cash.

The facility also 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 $150.0 million) under certain circumstances if certain lenders agree to commit to such an increase.

Amounts drawn under the facility are limited to (1) 85% of the net amount of eligible accounts receivable, plus (2) the lesser of (a) 70% of the value of the lower of cost or market of eligible inventory, or (b) 85% of the appraised net orderly liquidation value of all eligible inventory, plus (3) 100% of cash held in an account with Bank of America and subject to a control agreement with Bank of America, minus (4) such reserves as Bank of America, the agent, may establish. Advances on inventory are limited to $325.0 million. The facility includes a $400.0 million sub-limit for letters of credit, and any outstanding letters of credit will be deducted from availability under the facility.

At September 30, 2011, we 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 September 30, 2011, we had outstanding letters of credit totaling $17.7 million and borrowing availability of $382.3 million under the revolving credit facility.

In January 2006, we issued $250.0 million aggregate principal amount of 6 ⁵/8% senior notes due 2016. The 6 ⁵/8% senior notes are unsecured and were issued with an original issue discount of $0.8 million. There is no sinking fund and no scheduled amortization of the notes prior to maturity. The notes are subject to redemption and the holders may require us to repurchase the notes upon a change of control. 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 the 6 ⁵/8% senior notes.

The agreements governing the Senior Notes and the revolving credit facility each 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 these restrictions in the indenture governing the Senior Notes is currently suspended under the indenture because the Senior Notes are currently rated investment grade by at least two nationally recognized credit rating agencies. The most significant of the provisions in the indenture for the Senior Notes, 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 $0.20 per share (currently $0.0738 per share). If the restrictions in the Senior Notes indenture were currently effective, the indenture would not allow distributions in excess of $100.0 million 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.

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 $100.0 million or 25% 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 $70.0 million or 17.5% 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. However, we may make specified distributions up to an aggregate of $25.0 million and specified acquisitions up to an aggregate of $25.0 million if either we maintain a minimum borrowing availability of at least the greater of $70.0 million or 17.5% of the total bank commitments under our revolving credit facility or we meet the minimum fixed charge coverage ratio of 1.0:1 under our revolving credit facility. Notwithstanding the foregoing, we may make (1) investments up to $200.0 million in one or more joint ventures that own feedstock, raw material and ethylene pipeline, storage and fractionating facilities and (2) additional investments up to $55.0 million in Suzhou Huasu Plastics Co., Ltd. In addition, the Senior Notes indenture and the revolving credit facility impose certain restrictions on our ability to create liens, to engage in certain affiliate transactions and to engage in sale-leaseback transactions. However, the effectiveness of the restriction on our ability to engage in certain affiliate transactions in the indenture governing the Senior Notes is currently suspended under the indenture because the Senior Notes are currently rated investment grade by at least two nationally recognized credit rating agencies.

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. The interest rate on the waste disposal revenue bonds at September 30, 2011 and December 31, 2010 was 0.25% and 0.45%, respectively.

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.

Forward-looking statements can be identified by the use of words such as “believes,” “intends,” “may,” “should,” “could,” “anticipates,” “expected” or comparable terminology, or by discussions of strategies or trends. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot give any assurances that these expectations will prove to be correct. Forward-looking statements relate to matters such as:

•

future operating rates, margins, cash flow and demand for our products;

•

•

effects of pending legal proceedings; and

•

timing of and amount of capital expenditures.

We have based these statements on assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe were appropriate in the circumstances when the statements were made. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such statements. These statements are subject to a number of assumptions, risks and uncertainties, including those described in “Risk Factors” in the 2010 Form 10-K and the following:

•

general economic and business conditions;

•

the cyclical nature of the chemical industry;

•

the availability, cost and volatility of raw materials and energy;

•

uncertainties associated with the United States and worldwide economies, including those due to the global economic slowdown, the credit crisis and political tensions in the Middle East and elsewhere;

•

current and potential governmental regulatory actions in the United States and regulatory actions and political unrest in other countries;

•

industry production capacity and operating rates;

•

the supply/demand balance for our products;

•

•

instability in the credit and financial markets;

•

•

changes in laws or regulations;

•

technological developments;

•

our ability to implement our business strategies; and

•

creditworthiness of our customers.

Many of these 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 product feedstock flexibility and moving downstream into the olefins and vinyls products where pricing is more stable. We use derivative instruments in certain instances to reduce price volatility risk on feedstocks and products. Based on our open derivative positions at September 30, 2011, a hypothetical $0.10 increase in the price of a gallon of ethane would have decreased our income before taxes by $1.3 million and a hypothetical $0.10 increase in the price of a pound of ethylene would have decreased our income before taxes by $1.8 million. Additional information concerning derivative commodity instruments appears in Notes 8 and 9 to the consolidated financial statements.

Interest Rate Risk

We are exposed to interest rate risk with respect to fixed and variable rate debt. At September 30, 2011, we had variable rate debt of $10.9 million outstanding. All of the debt outstanding under our revolving credit facility (none was outstanding at September 30, 2011) 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 September 30, 2011 was 0.25%. 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, 2011, 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 and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934 as of the end of the period covered by this report. In the course of this evaluation, management considered certain internal control areas in which we have made and are continuing to make changes to improve and enhance controls. Based upon that evaluation, our President and Chief Executive Officer and our Senior 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, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
