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, 2011 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, 2011, filed with the SEC on February 23, 2012. 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, 2011.

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, 2012, its results of operations for the three and six months ended June 30, 2012 and 2011 and the changes in its cash position for the six months ended June 30, 2012 and 2011.

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, 2012 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 May 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update 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 requires, 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 Company adopted the new fair value measurement guidance as of January 1, 2012, and the adoption did not 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 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 FASB issued another accounting standards update on the presentation of other comprehensive income in December 2011, deferring the effective date for amendments to the presentation of reclassification adjustments of items out of accumulated other comprehensive income. In the interim, reclassifications out of accumulated other comprehensive income should be presented consistent with the current presentation requirements. All other requirements of the June 2011 accounting standards update are not affected by the December 2011 update. With the exception of the presentation of reclassification adjustments of items out of accumulated other comprehensive income, the Company adopted the guidance pertaining to the presentation of other comprehensive income as of January 1, 2012, and the adoption did not 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

WESTLAKE CHEMICAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(Unaudited)

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

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 Company adopted the new goodwill impairment test guidance as of January 1, 2012, and the adoption did not have a material impact on the Company’s consolidated financial position or results of operations.

Disclosures about Offsetting Assets and Liabilities

In December 2011, the FASB issued an accounting standards update on disclosures for offsetting assets and liabilities. The new accounting guidance requires companies to disclose both gross and net information about (1) instruments and transactions eligible for offset in the statement of financial position, and (2) instruments and transactions subject to an agreement similar to a master netting arrangement. The accounting standards update will be effective for reporting periods beginning on or after January 1, 2013 and is not expected to have an impact on the Company’s consolidated financial position or results of operations.

2. Accounts Receivable

Accounts receivable consist of the following:

Materials and supplies		53,365		48,048

Inventories	$	407,124	$	490,777

4. Property, Plant and Equipment

As of June 30, 2012, the Company had property, plant and equipment totaling $1,309,752. 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.

Depreciation expense on property, plant and equipment of $30,387 and $27,493 is included in cost of sales in the consolidated statements of operations for the three months ended June 30, 2012 and 2011, respectively. Depreciation expense on property, plant and equipment of $60,559 and $54,800 is included in cost of sales in the consolidated statements of operations for the six months ended June 30, 2012 and 2011, respectively.

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 $1,475 and $1,623 for the three months ended June 30, 2012 and 2011, respectively, and $3,125 and $3,127 for the six months ended June 30, 2012 and 2011, respectively.

Option activity and changes during the six months ended June 30, 2012 were as follows:


	Options			Weighted Average Exercise Price		Weighted Average Remaining Term (Years)		Aggregate Intrinsic Value
Outstanding at December 31, 2011		1,133,147		$	23.26
Granted		115,340			60.09
Exercised		(223,044	)		20.21
Cancelled		(1,278	)		43.92

Outstanding at June 30, 2012		1,024,165		$	28.05		6.5	$	25,693

Exercisable at June 30, 2012		648,698		$	20.92		5.9	$	20,331

For options outstanding at June 30, 2012, the options had the following range of exercise prices:


Range of Prices	Options Outstanding		Weighted Average Remaining Contractual Life (Years)
$14.24—$19.29		368,405		5.7
$20.53—$27.24		235,712		7.0
$30.07—$36.10		210,454		4.6
$45.83—$60.11		209,594		9.2

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 June 30, 2012. This amount changes based on the fair market value of the Company’s common stock. The total intrinsic value of options exercised was $7,432 and $943 for the three months ended June 30, 2012 and 2011, respectively, and $8,109 and $8,147 for the six months ended June 30, 2012 and 2011, respectively.

As of June 30, 2012, $4,280 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 2.0 years. Income tax benefit realized from the exercise of stock options was $1,977 and $286 for the three months ended June 30, 2012 and 2011, respectively, and $2,124 and $2,148 for the six months ended June 30, 2012 and 2011, 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 six months ended June 30, 2012 and 2011. Volatility was calculated using historical trends of the Company’s common stock price. There were no options granted during the three months ended June 30, 2012 and 2011.

8. 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, 2012. There were no derivative instruments designated by the Company as fair value hedges for the three and six months ended June 30, 2011. As of June 30, 2012, the Company had 45,360,000 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 six months ended June 30, 2012 and 2011.

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).

Interest Rate Risk Management

In order to manage its interest rate risk, the Company may enter into Treasury lock agreements to fix the Treasury yield component of the interest cost associated with anticipated financings. During June and July 2012, the Company entered into several Treasury lock agreements to fix the Treasury yield component of the interest cost of financing the issuance of senior notes. These Treasury locks were designated as cash flow hedges. The Company refinanced all $250,000 aggregate principal amount of its 6⁵/₈% senior notes due 2016 (the “2016 Notes”) through the issuance of $250,000 aggregate principal amount of its 3.60% senior notes due 2022 (the “2022 Notes”) in July 2012.

9. Fair Value Measurements

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

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

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

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

The 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, 2012
	Level 1			Level 2			Total
Derivative instruments
Risk management assets—Commodity forward contracts	$	1,379		$	8,670		$	10,049

Firm commitments
Hedged portion of firm commitment		—			3,262			3,262
Marketable securities
Available-for-sale equity securities		30,113			—			30,113

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 six months ended June 30, 2012 and 2011.

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 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 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.

10. Income Taxes

The effective income tax rate was 34.7% for the six months ended June 30, 2012. The effective income tax rate for the 2012 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 35.7% for the six months ended June 30, 2011. The effective income tax rate for the 2011 period was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, mostly offset by 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 June 30, 2012, 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. In January 2012, the Internal Revenue Service completed the audit of the Company for the 2009 tax year with no assessment.

11. Earnings per Share

The Company has unvested shares of restricted stock 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,
	2012			2011			2012			2011
Net income	$	115,501		$	81,049		$	203,314		$	164,593
Less:
Net income attributable to participating securities		(606	)		(715	)		(1,240	)		(1,492	)

Net income attributable to common shareholders	$	114,895		$	80,334		$	202,074		$	163,101

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

Excluded from the computation of diluted earnings per share are options to purchase 327,669 and 112,154 shares of common stock for the three months ended June 30, 2012 and 2011, respectively, and 346,957 and 178,522 shares of common stock for the six months ended June 30, 2012 and 2011, respectively. These options were outstanding during the periods reported but were excluded because the option exercise price was greater than the average market price of the shares.

Net periodic benefit cost	$	791		$	731		$	252	$	316	$	1,583		$	1,477		$	505	$	633

The Company contributed $1,021 and $796 to the Salaried pension plan in the first six months of 2012 and 2011, respectively, and contributed $659 and $432 to the Wage pension plan in the first six months of 2012 and 2011, respectively. The Company expects to make additional contributions of $1,841 to the Salaried pension plan and $1,264 to the Wage pension plan during the year ending December 31, 2012.

13. 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 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 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 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 $3,287 in 2011. 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

WESTLAKE CHEMICAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(Unaudited)

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

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 proceedings, which was denied on December 29, 2011.

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 currently 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 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. As a result of the audit, the EPA brought allegations that the Company had violated certain environmental laws and regulations pertaining to LDAR. The Company has agreed to settle this matter by paying a cash penalty of $500 and has recorded an accrual in such amount.

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.

15. Subsequent Events

On July 17, 2012, the Company issued $250,000 aggregate principal amount of the 2022 Notes. On July 30, 2012, the Company voluntarily redeemed all $250,000 aggregate principal amount of the 2016 Notes at a redemption price of 102.208% of the principal amount, plus accrued and unpaid interest to the redemption date. The Company used the net proceeds from the issuance of the 2022 Notes, plus cash on hand, to pay the redemption price of the 2016 Notes. As a result of the early redemption of the 2016 Notes, the Company expects to recognize $6,797 in non-operating expense in the third quarter of 2012 consisting of a pre-payment premium of $5,520 and a write-off of $1,277 in previously capitalized debt issuance costs.

The Treasury lock agreements executed by the Company to fix the Treasury yield component of the interest cost of financing the anticipated issuance of senior notes were settled in July 2012, subsequent to the issuance of the 2022 Notes. The Treasury locks were settled with an aggregate payment of $1,940 to the counterparties due to a decrease in the 10-year Treasury rates between inception and settlement of the Treasury lock agreements.

Subsequent events were evaluated through the date on which the financial statements were issued.

16. Guarantor Disclosures

As of June 30, 2012, the Company’s payment obligations under the 2016 Notes were fully and unconditionally guaranteed by each of its then existing subsidiaries that guaranteed other debt of the Company or of another guarantor of the 2016 Notes in excess of $5,000 (the “Guarantor Subsidiaries”). As of June 30, 2012, each Guarantor Subsidiary was 100% owned by Westlake Chemical Corporation. These guarantees were 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 did not guarantee the 2016 Notes (the “Non-Guarantor Subsidiaries”), together with consolidating adjustments 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, 2011 (the “2011 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.

Beginning in 2009 and continuing through the second quarter of 2012, a cost advantage for ethane-based ethylene producers over naphtha-based ethylene producers allowed a strong export market and higher margins for North American chemical producers, including Westlake. Increased global demand for polyethylene since 2010 has resulted in increased sales volumes and improved operating margins and cash flow for our Olefins segment. However, some olefins industry consultants predict that increases in worldwide ethylene and ethylene derivative capacity, which have occurred over the past four years, primarily in the Middle East and Asia, may continue. 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, impacted our Vinyls segment’s operating results in 2010 and 2011. However, since late 2010, the PVC industry has also 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 improved due to higher PVC resin export shipments. Looking forward, our Vinyls segment operating rates and margins may continue to be negatively impacted by the slow recovery of U.S. construction markets.

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 2012 and beyond, could have a negative effect on our financial condition, results of operations or cash flows.

Recent Developments

On July 17, 2012, we issued $250.0 million aggregate principal amount of 3.60% senior notes due 2022 (the “2022 Notes”). On July 30, 2012, we voluntarily redeemed all $250.0 million aggregate principal amount of our outstanding 6⁵/₈% senior notes due 2016 (the “2016 Notes”), at a redemption price of 102.208% of the principal amount, plus accrued and unpaid interest to the redemption date. We used the net proceeds from the issuance of the 2022 Notes, plus cash on hand, to pay the redemption price of the 2016 Notes. As a result of the early redemption of the 2016 Notes, we expect to recognize $6.8 million in non-operating expense in the third quarter of 2012 consisting of a pre-payment premium of $5.5 million and a write-off of $1.3 million in previously capitalized debt issuance cost.

On March 22, 2012, a fire occurred at the vinyl chloride monomer (VCM) unit at our Geismar, Louisiana vinyls complex, resulting in an unscheduled shut down of our Geismar complex. VCM is an intermediate product used in the production of PVC at our Geismar complex. We restarted the PVC and VCM plants at our Geismar complex in late April and mid May, respectively, but operated both plants at reduced capacity until we returned them to normal operations in June 2012. In addition to the lost production resulting from the shut down, we incurred repair costs and unabsorbed fixed manufacturing costs in connection with the shutdown, which negatively impacted our Vinyls segment’s income from operations in the first six months of 2012.

On January 13, 2012, we announced that we submitted a proposal to Georgia Gulf Corporation (“Georgia Gulf”) to acquire all of the outstanding shares of Georgia Gulf common stock for $30.00 per share in cash, or a total of approximately $1.1 billion. Our proposal was not subject to financing conditions. Georgia Gulf rejected our proposal on January 16, 2012 and adopted a stockholder rights plan. On February 1, 2012, we announced that we were increasing our offer to $35.00 per share in cash, or a total of approximately $1.2 billion, with the possibility of offering our common stock as part of the offer consideration. On that date, Georgia Gulf publicly rejected our increased offer. On May 4, 2012, we announced that we had withdrawn our proposal to acquire all of the outstanding shares of common stock of Georgia Gulf. We also announced that we planned to liquidate our holdings of Georgia Gulf common stock as market conditions permitted. As of June 30, 2012, we no longer held any shares of Georgia Gulf common stock.

Summary

For the quarter ended June 30, 2012, net income was $115.5 million, or $1.72 per diluted share, on net sales of $914.0 million. This represents an increase in net income of $34.5 million, or $0.51 per diluted share, over the quarter ended June 30, 2011 net income of $81.0 million, or $1.21 per diluted share, on net sales of $925.0 million. Net income for the second quarter of 2012 benefited by $8.5 million, or $0.13 per share, as a result of a pre-tax gain of $16.0 million from the sale of securities, partially offset by pre-tax expense of $3.0 million related to our proposal to acquire Georgia Gulf, which was terminated. Net sales for the second quarter of 2012 decreased by $11.0 million compared to net sales for the second quarter of 2011, mainly attributable to lower sales prices for most of our major products and lower sales volumes for PVC resin and building products, partially offset by higher olefins and feedstock sales volumes. Income from operations was $171.0 million for the second quarter of 2012 as compared to $138.4 million for the second quarter of 2011. Income from operations for the second quarter of 2012 benefited primarily from lower feedstock and energy costs, improved building products margins and higher caustic sales volume as compared to the prior year period. Industry ethane prices declined 48.1% and industry propane prices declined 34.7% in the second quarter of 2012 as compared to the second quarter of 2011. The second quarter of 2011 was negatively impacted by a number of factors, including an unscheduled outage at one of our ethylene units in Lake Charles, Louisiana caused by a weather related power supply failure from a third party power provider, the turnaround of our Calvert City, Kentucky facility and the closure of our Springfield, Kentucky PVC pipe production facility.

For the six months ended June 30, 2012, net income was $203.3 million, or $3.03 per diluted share, on net sales of $1,948.8 million. This represents an increase in net income of $38.7 million, or $0.57 per diluted share, from the six months ended June 30, 2011 net income of $164.6 million, or $2.46 per diluted share, on net sales of $1,792.3 million. Net sales for the six months ended June 30, 2012 increased by $156.5 million compared to the prior year period mainly due to higher olefins and feedstock sales volumes. Income from operations was $316.6 million for the six months ended June 30, 2012 as compared to $279.0 million for the six months ended June 30, 2011. The increase in income from operations was primarily attributable to higher vinyls and olefins integrated product margins as compared to the prior year period. The improved margins were primarily due to a significant decrease in feedstock costs as industry ethane prices decreased 32.4% and industry propane prices decreased 21.8%. Income from operations for the six months ended June 30, 2011 was negatively impacted by the unscheduled Lake Charles outage, the Calvert City turnaround, the closure of the PVC pipe facility and higher operating costs resulting from a reduction in our ethylene operating rates in Lake Charles in the first quarter of 2011 due to a fire at a third party storage facility in Mont Belvieu, Texas.

RESULTS OF OPERATIONS

Second Quarter 2012 Compared with Second Quarter 2011

Net Sales. Net sales decreased by $11.0 million, or 1.2%, to $914.0 million in the second quarter of 2012 from $925.0 million in the second quarter of 2011, primarily attributable to lower sales prices for most of our major products and lower sales volume for PVC resin, building products and polyethylene, partially offset by higher olefins and feedstock sales volumes. Average sales prices for the second quarter of 2012 decreased by 10.3% as compared to the second quarter of 2011. Overall sales volume increased by 9.1% as compared to the second quarter of 2011.

Gross Profit. Gross profit margin percentage increased to 22.1% for the second quarter of 2012 from 18.1% for the second quarter of 2011, driven primarily by improved olefins integrated product margins attributable to lower feedstock and energy costs. The second quarter 2012 gross profit margin percentage also benefited from improved PVC resin and building products margins and higher caustic sales volume. Our raw material cost in both segments normally tracks industry prices, which experienced a decrease of 48.1% and 34.7% for ethane and propane, respectively, as compared to the second quarter of 2011. Sales prices decreased an average of 10.3% for the second quarter of 2012 as compared to the second quarter of 2011.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the second quarter of 2012 increased by $2.2 million as compared to the second quarter of 2011 primarily attributable to expenses associated with our terminated proposal to acquire Georgia Gulf, partially offset by a decrease in consulting fees and a decrease in the facility fee for our senior secured revolving credit facility.

Interest Expense. Interest expense decreased by $1.2 million to $11.6 million in the second quarter of 2012 from $12.8 million in the second quarter of 2011 largely as a result of increased capitalized interest on major capital projects in the second quarter of 2012. Debt balances and interest rates remained relatively unchanged from the prior year period.

Gain from Sales of Equity Securities. We liquidated our holdings of shares of Georgia Gulf common stock in the second quarter of 2012. As a result of the disposition, we recognized a gain of $16.0 million in non-operating income in the second quarter of 2012.

Other Income, Net. Other income, net decreased to $1.1 million in the second quarter of 2012 from $1.6 million in the second quarter of 2011, mainly attributable to lower equity in income from our joint ventures.

Income Taxes. The effective income tax rate was 34.5% for the second quarter of 2012. The effective income tax rate for the second quarter of 2012 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 36.3% for the second quarter of 2011. The effective income tax rate for the second quarter of 2011 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 $27.4 million, or 4.2%, to $672.7 million in the second quarter of 2012 from $645.3 million in the second quarter of 2011, primarily due to higher ethylene and feedstock sales volumes as compared to the prior year period. Average sales prices for the Olefins segment decreased by 12.7% in the second quarter of 2012 as compared to the second quarter of 2011. Average sales volumes increased by 16.9% in the second quarter of 2012 as compared to the second quarter of 2011.

Income from Operations. Income from operations increased by $23.1 million, or 17.4%, to $155.9 million in the second quarter of 2012 from $132.8 million in the second quarter of 2011. This increase was mainly attributable to higher olefins integrated product margins as compared to the prior year period. Margins improved primarily as a result of significantly lower feedstock and energy costs, which were only partially offset by lower sales prices. Trading activity in the second quarter of 2012 resulted in a loss of $1.6 million as compared to a gain of $0.5 million in the second quarter of 2011. Income from operations for the second quarter of 2011 was negatively impacted by the lost ethylene production, repair costs and unabsorbed fixed manufacturing costs incurred in connection with the ethylene unit outage in Lake Charles.

Vinyls Segment

Net Sales. Net sales decreased by $38.5 million, or 13.8%, to $241.2 million in the second quarter of 2012 from $279.7 million in the second quarter of 2011. This decrease was primarily attributable to lower sales prices for PVC resin and lower sales volumes for PVC resin and building products. PVC resin sales volume was negatively impacted by the lower operating rates at our Geismar vinyls complex in the second quarter of 2012. Average sales prices for the Vinyls segment decreased by 4.8% in the second quarter of 2012 as compared to the second quarter of 2011. Average sales volumes for the Vinyls segment decreased by 9.0% in the second quarter of 2012 as compared to the second quarter of 2011.

Income from Operations. Income from operations increased by $12.3 million, or 119.4%, to $22.6 million in the second quarter of 2012 from $10.3 million in the second quarter of 2011. This increase was primarily driven by lower feedstock costs, improved PVC resin and building products margins and higher caustic sales volume as compared to the prior year period. The second quarter 2012 income from operations was negatively impacted by the unscheduled shut down of our Geismar vinyls complex and the lower operating rates at that complex as a result of operational issues related to the fire at the complex in March 2012. We expensed approximately $9.5 million of costs associated with that event in the second quarter of 2012. Income from operations for the second quarter of 2011 was negatively impacted by the turnaround at our Calvert City facility and the closure of our Springfield PVC pipe facility. While operating results for the second quarter of 2012 improved compared to the second quarter of 2011, our Vinyls segment continued to be negatively impacted by weakness in the U.S. construction markets and budgetary constraints in municipal spending.

Six Months Ended June 30, 2012 Compared with Six Months Ended June 30, 2011

Net Sales. Net sales increased by $156.5 million, or 8.7%, to $1,948.8 million for the first six months of 2012 from $1,792.3 million for the first six months of 2011, primarily driven by higher olefins and feedstock sales volumes. Average sales prices for the first six months of 2012 decreased by 3.0% as compared to the first six months of 2011. Overall sales volume increased by 11.7% as compared to the first six months of 2011.

Gross Profit. Gross profit margin percentage of 19.2% for the six months ended June 30, 2012 increased from the 18.7% gross profit margin percentage for the six months ended June 30, 2011. The improvement in gross profit margin percentage was primarily due to lower feedstock and energy costs. Our raw material cost in both segments normally tracks industry prices, which experienced a decrease of 32.4% and 21.8% for ethane and propane, respectively, as compared to the six months ended June 30, 2011. Sales prices decreased an average of 3.0% for the six months ended June 30, 2012 as compared to the prior year period.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the six months ended June 30, 2012 increased by $2.2 million as compared to the six months ended June 30, 2011 mainly attributable to expenses associated with our terminated proposal to acquire Georgia Gulf, partially offset by a decrease in the facility fee for our senior secured revolving credit facility.

Interest Expense. Interest expense decreased by $2.0 million to $23.7 million in the first six months of 2012, primarily due to increased capitalized interest on major capital projects in the first six months of 2012. Debt balances and interest rates remained relatively unchanged from the prior year period.

Other Income, Net. Other income, net decreased marginally by $0.3 million to $2.5 million in the first six months of 2012 from $2.8 million in the first six months of 2011 as higher interest income attributable to higher average cash balances for the period was offset by lower equity in income from our joint ventures.

Income Taxes. The effective income tax rate was 34.7% for the six months ended June 30, 2012. The effective income tax rate for the 2012 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 35.7% for the six months ended June 30, 2011. The effective income tax rate for the 2011 period was above the U.S. federal statutory rate of 35.0% primarily due to state income taxes, mostly offset by the domestic manufacturing deduction.

Olefins Segment

Net Sales. Net sales increased by $154.6 million, or 12.4%, to $1,405.0 million for the six months ended June 30, 2012 from $1,250.4 million for the six months ended June 30, 2011, primarily due to higher ethylene and feedstock sales volumes. Average sales prices for the Olefins segment decreased by 5.2% in the first six months of 2012 as compared to the first six months of 2011. Average sales volumes increased by 17.6% in the first six months of 2012 as compared to the first six months of 2011.

Income from Operations. Income from operations increased by $7.1 million, or 2.6%, to $285.1 million in the first six months of 2012 from $278.0 million in the first six months of 2011. This increase was mainly attributable to higher olefins integrated product margins as compared to the prior year period. Margins improved as a result of lower feedstock and energy costs, which were only partially offset by lower sales prices. Trading activity for the six months ended June 30, 2012 resulted in a loss of $1.0 million as compared to a gain of $0.5 million for the prior year period. The first six months of 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.

Vinyls Segment

Net Sales. Net sales increased marginally by $1.9 million, or 0.4%, to $543.8 million for the six months ended June 30, 2012 from $541.9 million for the six months ended June 30, 2011. This increase was primarily attributable to higher caustic sales prices and sales volume and higher building products sales prices, mostly offset by lower PVC resin sales volume and sales prices as compared to the prior year period. Average sales prices for the Vinyls segment increased by 2.1% in the first six months of 2012 as compared to the first six months of 2011, while average sales volumes decreased by 1.7%.

Income from Operations. Income from operations increased by $36.3 million to $43.7 million for the six months ended June 30, 2012 from $7.4 million for the six months ended June 30, 2011. This increase was primarily driven by lower feedstock and energy costs and higher caustic and building products margins as compared to the prior year period. The 2012 period income from operations was negatively impacted by the lost production, lost sales and the expensing of approximately $11.5 million of costs associated with the fire at our Geismar complex. The Vinyls segment’s operating results for the first six months of 2011 were negatively impacted by the turnaround at the Calvert City facility and the closure of the Springfield PVC pipe facility in the second quarter of 2011.

CASH FLOW DISCUSSION FOR SIX MONTHS ENDED JUNE 30, 2012 AND 2011

Cash Flows

Operating Activities

Operating activities provided cash of $322.6 million in the first six months of 2012 compared to cash provided of $125.3 million in the first six months of 2011. The $197.3 million increase in cash flows from operating activities was mainly due to an increase in income from operations and a decrease in working capital requirements, as compared to the prior year period. Income from operations increased by $37.6 million in the first six months of 2012 primarily as a result of higher vinyls and olefins integrated product margins

as compared to the prior year period. 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, provided cash of $46.3 million in the first six months of 2012, compared to $124.4 million of cash used in the first six months of 2011, a favorable change of $170.7 million. This change was mainly due to a decrease in inventory during the 2012 period primarily attributable to lower feedstock costs.

Investing Activities

Net cash used for investing activities during the first six months of 2012 was $97.7 million as compared to net cash used for investing activities of $66.3 million in the first six months of 2011. Capital expenditures were $140.6 million in the first six months of 2012 compared to $69.2 million in the first six months of 2011. The higher capital expenditures in the 2012 period were largely attributable to capital expenditures incurred on the construction of the new chlor-alkali plant at our Geismar facility, the expansion of the ethylene unit at our Lake Charles complex and the modernization of the ethylene furnaces at our Calvert City complex. The remaining capital expenditures in the first six months of 2012 and capital expenditures in the first six months of 2011 primarily related to projects to improve production capacity or reduce costs and safety and environmental projects at our various facilities. Construction of assets pending sale-leaseback totaled $1.8 million in the first six months of 2012 and pertained to the construction of caustic barges necessary to transport the caustic soda to be produced at the new chlor-alkali plant at our Geismar facility. Purchases of equity securities in the first six months of 2012 totaled $3.0 million and comprised of shares of Georgia Gulf common stock. We received aggregate proceeds of $46.0 million from the sale of all our shares of Georgia Gulf common stock during the first six months of 2012.

Financing Activities

Net cash provided by financing activities during the first six months of 2012 was $59.8 million as compared to net cash provided of $23.1 million in the first six months of 2011. The 2012 period activity was primarily related to a $76.0 million draw-down of our restricted cash for use for eligible capital expenditures and proceeds of $4.5 million from the exercise of stock options. Net cash provided by financing activities was partially offset by the $10.8 million of repurchases of shares of our common stock and $9.8 million payment of cash dividends. The 2011 period activity was primarily related to the draw-down of our restricted cash and proceeds from the exercise of stock options, partially offset by the $8.4 million 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 December 2011, we announced plans to perform a major modernization of the ethylene furnaces at our Calvert City complex. We currently expect the modernization to be completed by mid-2013. This capital project is currently estimated to cost approximately $40.0 million and is expected to be funded with cash on hand, cash flow from operations, and if necessary, our revolving credit facility and other external financing.

In August 2011, our Board of Directors authorized a stock repurchase program totaling $100.0 million. As of June 30, 2012, we had repurchased 284,493 shares of our common stock for an aggregate purchase price of approximately $13.3 million under this program. During the three months ended June 30, 2012, we repurchased 214,677 shares of our common stock at a cost of approximately $10.8 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 uses and may also be sold in 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 facility. The project is currently estimated to cost in the range of $370.0 million to $420.0 million and is targeted for start-up in the second half of 2013. These projects will be funded with cash on hand, cash flow from operations, the net proceeds from certain of the revenue bonds issued by 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 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 $1,131.0 million at June 30, 2012, which included cash and cash equivalents of $1,110.5 million and restricted cash of $20.5 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 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 June 30, 2012, our long-term debt, including current maturities, totaled $764.6 million, consisting of $250.0 million principal amount of 2016 Notes (less the unamortized discount of $0.3 million), $100.0 million of 6¹/₂% senior notes due 2029, $250.0 million of 6³/₄% senior notes due 2032, $89.0 million of 6¹/₂% senior notes due 2035 (the “2035 GO Zone 6¹/₂% Notes”), $65.0 million of 6¹/₂% senior notes due 2035 (the “2035 IKE Zone 6¹/₂% 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 6¹/₂% senior notes due 2029, the 6³/₄% senior notes due 2032, the 2035 GO Zone 6¹/₂% Notes and the 2035 IKE Zone 6¹/₂% 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 June 30, 2012, debt outstanding under the tax-exempt waste disposal revenue bonds bore interest at a variable rate. As of June 30, 2012, 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.

On July 30, 2012, we voluntarily redeemed all $250.0 million aggregate principal amount of our 2016 Notes at the redemption price of 102.208% of the principal amount, plus accrued and unpaid interest to the redemption date. We used net proceeds of $246.7 million from the issuance of the 2022 Notes issued in July 2012, plus cash on hand, to pay the redemption price of the 2016 Notes.

Revolving Credit Facility

We have a $400.0 million senior secured revolving credit facility. 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 $150.0 million) under certain circumstances if certain lenders agree to commit to such an increase.

At June 30, 2012, 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 June 30, 2012, we had outstanding letters of credit totaling $15.7 million and borrowing availability of $384.3 million under the revolving credit facility.

Our revolving credit facility requires 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.

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. 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 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt” in the 2011 Form 10-K for more information on the revolving credit facility.

GO Zone and IKE Zone Bonds

As of June 30, 2012, we had drawn $43.9 million of the proceeds from the issuance of the 2035 IKE Zone 6¹/₂% Notes. The balance of the proceeds, plus interest income, remains with the trustee, and is classified on our consolidated balance sheets 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 6¹/₂% senior notes due 2029, 6³/₄% senior notes due 2032 and 2035 GO Zone 6¹/₂% Notes as of December 31, 2010, March 31, 2012 and June 30, 2012, respectively. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt” in the 2011 Form 10-K for more information on the 6¹/₂% senior notes due 2029, the 6³/₄% senior notes due 2032, the 2035 GO Zone 6¹/₂% Notes and the 2035 IKE Zone 6¹/₂% 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.

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 $0.20 per share (currently $0.0738 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 and 6⁵/₈% Senior Notes due 2016

On July 17, 2012, we issued $250.0 million aggregate principal amount of the 2022 Notes, the net proceeds of which, together with cash on hand, were used, on July 30, 2012 to redeem all $250.0 million principal amount of the 2016 Notes, at the redemption price of 102.208% of the principal amount, plus accrued and unpaid interest to the redemption date. As a result of the early redemption of the 2016 Notes, we expect to recognize $6.8 million in non-operating expense in the third quarter of 2012 consisting of a pre-payment premium of $5.5 million and a write-off of $1.3 million in previously capitalized debt issuance costs.

The 2022 Notes 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 2022 Notes prior to maturity. We may optionally redeem the 2022 Notes at any time and from time to time, and the holders may require us to repurchase the 2022 Notes upon the occurrence of both a “change of control” and, within 60 days of such change of control, a “below investment grade rating event” (as such terms are defined in the supplemental indenture governing the 2022 Notes). All domestic subsidiaries that guarantee other debt of ours or of another guarantor of the 2022 Notes in excess of $5.0 million are guarantors of the 2022 Notes.

Revenue Bonds

In December 1997, we entered into a loan agreement with a public trust established for public purposes for the benefit of the Parish of Calcasieu, Louisiana. The public trust issued $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.

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.

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 2011 Form 10-K and the following:

•

general economic and business conditions;

•

•

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 June 30, 2012, a hypothetical $0.10 increase in the price of a gallon of ethane would have increased our income before taxes by $1.6 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 June 30, 2012, 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, 2012) 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, 2012 was 0.35%. 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, 2012, 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, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
