EARNINGS BEFORE INTEREST AND TAXES

Earnings before interest and taxes (“EBIT”) by segment consists of net sales less related costs and expenses and are presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBIT for our reportable segments and are included in the Corporate, Other and Eliminations category.

The following table summarizes EBIT by segment (in millions):

4. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes.

The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with counterparties generally contain right of offset provisions. These provisions effectively reduce the Company’s exposure to credit risk in situations where the Company has gain and loss positions outstanding with a single counterparty. It is the Company’s policy to offset on the Consolidated Balance Sheets the amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master netting agreement. As of June 30, 2012, and December 31, 2011, the Company did not have any amounts on deposit with any of its counterparties, nor did any of its counterparties have any amounts on deposit with the Company.

The following table presents the fair value of derivatives and hedging instruments and the respective location on the Consolidated Balance Sheets (in millions):

			Fair Value at

Cash Flow Hedges

The Company uses forward and swap contracts, which qualify as cash flow hedges, to manage forecasted exposure to natural gas prices. The effective portion of the change in the fair value of cash flow hedges is deferred in accumulated OCI and is subsequently recognized in cost of sales on the Consolidated Statements of Earnings (Loss) for commodity hedges, when the hedged item impacts earnings. Changes in the fair value of derivative assets and liabilities designated as hedging instruments are shown in other within operating activities on the Consolidated Statement of Cash Flows. Any portion of the change in fair value of derivatives designated as hedging instruments that is determined to be ineffective is recorded in other (income) expenses on the Consolidated Statements of Earnings (Loss).

The Company currently has natural gas derivatives designated as hedging instruments that mature within 15 months. The Company’s policy is to hedge up to 75% of its total forecasted natural gas exposures for the next two months, up to 50% of its total forecasted natural gas exposures for the following four months, and lesser amounts for the remaining periods. Based on market conditions, approved variation from the standard policy may occur. The Company performs an analysis for effectiveness of its derivatives designated as hedging instruments at the end of each quarter based on the terms of the contract and the underlying item being hedged.

As of June 30, 2012, $2 million of losses included in accumulated OCI on the Consolidated Balance Sheets relate to contracts that will impact earnings during the next 12 months. Transactions and events that are expected to occur over the next 12 months that will necessitate recognizing these deferred amounts include the recognition of the hedged item through earnings.

4. DERIVATIVE FINANCIAL INSTRUMENTS (continued)

Fair Value Hedges

The Company manages its interest rate exposure by balancing the mixture of its fixed and variable rate instruments through interest rate swaps. The swaps are carried at fair value and recorded as other assets or liabilities, with the offset to long-term debt on the Consolidated Balance Sheets. Changes in the fair value of these swaps and that of the related debt are recorded in interest expense, net on the Consolidated Statements of Earnings (Loss). In the fourth quarter of 2011, the Company terminated all existing interest rate swaps.

Other Derivatives

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in other (income) expenses on the Consolidated Statements of Earnings (Loss).

As a result of first-quarter 2009 capacity curtailments taken at certain facilities, the normal purchase scope exception was no longer met for one of the Company’s energy supply contracts. The contract was required to be marked to market each quarter through its termination date of January 31, 2012.

5. GOODWILL AND OTHER INTANGIBLE ASSETS

Intangible assets and goodwill consist of the following (in millions):

June 30, 2012	Weighted Average Useful Life		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Amortizable intangible assets:

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

The changes in the net carrying amount of goodwill by segment are as follows (in millions):

	Composites			Building Materials		Total
Balance as of December 31, 2011	$	57		$	1,087	$	1,144
Foreign currency adjustments		(1	)		-		(1	)
Balance as of June 30, 2012	$	56		$	1,087	$	1,143

Other Intangible Assets

The Company expects the ongoing amortization expense for amortizable intangible assets to be approximately $21 million in each of the next five fiscal years. The Company’s future cash flows are not materially impacted by its ability to extend or renew agreements related to our amortizable intangible assets.

Goodwill

The Company tests goodwill and indefinite-lived intangible assets for impairment during the fourth quarter of each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying amount. No testing was deemed necessary in the second quarter of 2012.

6. PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment consist of the following (in millions):

	June 30, 2012			Dec. 31, 2011
Land	$	219		$	221
Buildings and leasehold improvements		729			727
Machinery and equipment		3,018			2,932
Construction in progress		318			268
		4,284			4,148
Accumulated depreciation		(1,380	)		(1,244	)
Property, plant and equipment, net	$	2,904		$	2,904

Machinery and equipment includes certain precious metals used in our production tooling, which comprise approximately 20% of total machinery and equipment as of June 30, 2012, and December 31, 2011. Precious metals used in our production tooling are depleted as they are consumed during the production process, which typically represents an annual expense of less than 3% of the outstanding carrying value.

7. DIVESTITURES

On May 18, 2011, the Company sold its Composites glass reinforcements facility in Capivari, Brazil, to Chongqing Polycomp International Company (“CPIC”), an unrelated third party. At closing, the Company received $55 million in cash and an additional $6 million was placed into escrow to satisfy any potential adjustments or claims.

9. COST REDUCTION ACTIONS

2012 Cost Reduction Actions

As a result of evaluating market conditions, we took actions to improve the competitive position of our global manufacturing network by closing certain facilities in Europe along with other actions that align with our objectives in the region. In conjunction with these actions, the Company recorded $32 and $87 million in charges related to cost reduction actions and related items for the three and six months ended June 30, 2012, respectively; of which, $2 and $36 million is related to severance and is included in charges related to cost reduction actions on the Consolidated Statements of Earnings (Loss). The $30 and $51 million in other related charges, respectively, relates primarily to accelerated depreciation and is included in cost of sales on the Consolidated Statements of Earnings (Loss). Cash payments related to these activities will continue through 2015. The Company will continue to evaluate its global network to ensure it has the appropriate capacity to respond to future anticipated demand around the world.

Composites

For the three and six months ended June 30, 2012, the Company’s actions resulted in $32 and $82 million in charges; of which $2 and $34 million was related to severance costs and $30 and $48 million was related to other charges, respectively. The $30 million and $48 million of other charges consist of $17 and $34 million in accelerated depreciation and $13 and $14 million in other related charges, respectively.

The Company anticipates incurring approximately $50 million in additional charges throughout 2012 and into 2013 related to these actions, of which $6 million will be presented as charges related to cost reduction actions on the Consolidated Statements of Earnings (Loss).

Senior Notes

The Company issued $350 million of senior notes on June 3, 2009, and $1.2 billion of senior notes on October 31, 2006, which are collectively referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company.

The Senior Notes are fully and unconditionally guaranteed by each of the Company’s current and future domestic subsidiaries that are a borrower or guarantor under the Company’s Credit Agreement (as defined below). The guarantees are unsecured and rank equally in right of payment with all other existing and future senior unsecured indebtedness of the guarantors. The guarantees are effectively subordinated to existing and future secured debt of the guarantors to the extent of the assets securing that indebtedness.

The Company has the option to redeem all or part of the Senior Notes at any time at a “make whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of June 30, 2012.

10. DEBT (continued)

In the fourth quarter of 2011, the Company terminated all existing interest rate swaps. The swaps were carried at fair value and recorded as other assets or liabilities, with a fair value adjustment to long-term debt on the Consolidated Balance Sheets. The fair value adjustment to debt will be amortized through 2016 as a reduction to interest expense in conjunction with the maturity date of the notes.

Senior Credit Facilities

On May 26, 2010, the Company entered into a credit agreement (the “Credit Agreement”) that established a new $800 million multi-currency senior revolving credit facility (the “Senior Revolving Credit Facility”). Also on May 26, 2010, the Company terminated the credit agreement dated as of October 31, 2006, which contained a $1.0 billion multi-currency senior revolving credit facility (the “Prior Revolving Credit Facility”) and a $600 million senior term loan facility.

The available principal amount of $800 million on the Senior Revolving Credit Facility includes both borrowings and letters of credit. The Company amended the Senior Revolving Credit Facility in July 2011 to extend the maturity to July 2016 and reduce the pricing. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate or LIBOR plus a spread.

The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a senior unsecured credit agreement. The Company was well within compliance with these covenants as of June 30, 2012.

The Company had $7 million and $42 million of letters of credit outstanding under the Senior Revolving Credit Facility at June 30, 2012 and December 31, 2011, respectively.

Receivables Securitization Facility

Included in long-term debt on the Consolidated Balance Sheets are amounts outstanding under a Receivable Purchase Agreement (the “RPA”). Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $250 million RPA with certain financial institutions. The securitization facility was amended in the fourth quarter of 2011 to extend maturity to December 2014. At June 30, 2012, the Company utilized the full amount permitted under the terms of the receivables securitization facility. The Company had $38 million of letters of credit outstanding under the receivables securitization facility at June 30, 2012. There were no letters of credit outstanding under the receivables securitization facility at December 31, 2011.

The receivables securitization facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a securitization facility. The Company was well within compliance with these covenants as of June 30, 2012.

Owens Corning Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers party to the RPA. Owens Corning Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of Owens Corning Receivables LLC’s assets prior to any assets or value in Owens Corning Receivables LLC becoming available to Owens Corning Receivables LLC’s equity holders. The assets of Owens Corning Receivables LLC are not available to pay creditors of the Company or any other affiliates of the Company or Owens Corning Sales, LLC.

Short-Term Debt

At June 30, 2012 and December 31, 2011, short-term borrowings were $24 million and $28 million, respectively. The short-term borrowings for both periods consisted of various operating lines of credit and working capital facilities. Certain of these borrowings are collateralized by receivables, inventories or property. The borrowing facilities are typically for one-year renewable terms. The weighted average interest rate on short-term borrowings was approximately 6.3% for June 30, 2012, and 7.4% for December 31, 2011.

11. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. The unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits.

The following tables provide information regarding pension expense recognized (in millions):

	Three Months Ended June 30, 2012									Three Months Ended June 30, 2011

During July of 2012, Congress passed the “Moving Ahead for Progress in the 21^st Century Act,” which included pension funding stabilization provisions. The measure, which is designed to stabilize the discount rate used to determine funding requirements from the effects of interest rate volatility, reduces the Company’s United States Pension Plan contributions by approximately $13 million during 2012.

The Company now expects to contribute approximately $36 million in cash to the United States Pension Plans and another $21 million to non-United States plans during 2012. The Company made cash contributions of approximately $30 million to the plans during the six months ended June 30, 2012.

Postemployment and Postretirement Benefits Other than Pension Plans

The Company maintains healthcare and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

12. CONTINGENT LIABILITIES AND OTHER MATTERS

Litigation

The Company is involved in various legal proceedings relating to employment, product liability and other matters. The Company regularly reviews the status of these proceedings along with legal counsel. Liabilities for such items are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s operations or financial condition taken as a whole.

Environmental Matters

We have been deemed by the Environmental Protection Agency (“EPA”) to be a Potentially Responsible Party (“PRP”) with respect to certain sites under the Comprehensive Environmental Response Compensation and Liability Act. We have also been deemed a PRP under similar state or local laws and in other instances other PRPs have brought suits against us as a PRP for contribution under such federal, state, or local laws. At June 30, 2012, we had environmental remediation liabilities as a PRP at 19 sites where we have a continuing legal obligation to either complete remedial actions or contribute to the completion of remedial actions as part of a group of PRPs. For these sites we estimate a reserve to reflect environmental liabilities that have been asserted or are probable of assertion, in which liabilities are probable and reasonably estimable. At June 30, 2012, our reserve for such liabilities was $8 million.

12. CONTINGENT LIABILITIES AND OTHER MATTERS (continued)

Other Items

On December 17, 2010, the French tax authorities made a claim in the amount of approximately 123 million Euros against a subsidiary the Company acquired as part of the acquisition of Saint-Gobain’s reinforcement and composite fabrics business in 2007 (the “2007 Acquisition”). The claim relates to transactions that occurred prior to the closing of the 2007 Acquisition. Pursuant to the purchase agreement governing the 2007 Acquisition, Saint-Gobain is required to indemnify Owens Corning and its subsidiaries for pre-closing tax claims and related damages, attorney fees and expenses. On July 17, 2012, the Company received a communication from the French tax authorities rescinding their original claim against the subsidiary of the Company. The Company does not expect any further inquiries regarding the claim.

13. STOCK COMPENSATION

2010 Stock Plan

On April 22, 2010, the Company’s stockholders approved the Owens Corning 2010 Stock Plan (the “2010 Stock Plan”), which replaced the Owens Corning 2006 Stock Plan (the “2006 Stock Plan”), as amended and restated. The 2010 Stock Plan authorizes grants of stock options, stock appreciation rights, stock awards, restricted stock awards, restricted stock units, bonus stock awards and performance stock awards. Such shares of common stock include shares that were available but not granted, or which were granted but were not issued or delivered due to expiration, termination, cancellation or forfeiture of such awards. At June 30, 2012, the number of shares remaining available under the 2010 Stock Plan for all stock awards was 2.6 million.

Stock Options

The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four-year vesting period. In general, the exercise price of each option awarded was equal to the market price of the Company’s common stock on the date of grant and an option’s maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers.

During the six months ended June 30, 2012, 409,700 stock options were granted with a weighted-average grant date fair value of $15.27. Assumptions used in the Company’s Black-Scholes valuation model to estimate the grant date fair value were expected volatility of 45.8%, expected dividends of 0%, expected term of 6.26 years and a risk-free interest rate of 1.1%.

During the three and six months ended June 30, 2012, the Company recognized expense of $1 million and $2 million respectively, related to the Company’s stock options. During the three and six months ended June 30, 2011, the Company recognized expense of $1 million and $2 million respectively, related to the Company’s stock options. As of June 30, 2012, there was $11 million of total unrecognized compensation cost related to stock options. That cost is expected to be recognized over a weighted-average period of 2.86 years. The total aggregate intrinsic value of options outstanding as of June 30, 2012 and 2011 was $11 million and $37 million.

Restricted Stock Awards and Restricted Stock Units

The Company has granted restricted stock awards and restricted stock units (collectively referred to as “restricted stock”) under its stockholder approved stock plans. Compensation expense for restricted stock is measured based on the market price of the stock at date of grant and is recognized on a straight-line basis over the four-year vesting period. Stock restrictions are subject to alternate vesting plans for death, disability, approved early retirement and involuntary termination, over various periods ending in 2015.

During the three and six months ended June 30, 2012, the Company recognized expense of $4 million and $8 million respectively, related to the Company’s restricted stock. During the three and six months ended June 30, 2011, the Company recognized expense of $3 million and $6 million respectively. As of June 30, 2012, there was $30 million of total unrecognized compensation cost related to restricted stock. That cost is expected to be recognized over a weighted-average period of 2.96 years. The total fair value of shares vested during the six months ended June 30, 2012 and 2011 was $11 million and $8 million, respectively.

A summary of the status of the Company’s plans that had restricted stock issued as of June 30, 2012, and changes during the six months ended June 30, 2012, are presented below.

Performance Stock Awards and Performance Stock Units

The Company has granted performance stock awards and performance stock units (collectively referred to as “PSUs”) as a part of its long-term incentive plan, of which 50% will be settled in stock and 50% will be settled in cash. The number of the PSUs ultimately distributed is contingent on meeting various company or stockholder return goals.

Compensation expense for PSUs settled in stock is measured based on the grant date fair value and is recognized on a straight-line basis over the vesting period. Compensation expense for PSUs settled in cash is measured based on the fair value at the end of each quarter and is recognized on a straight-line basis over the vesting period. Vesting will be pro-rated based on the number of full months employed during the performance period in the case of death, disability, change in control or involuntary termination, and pro-rated awards earned will be paid at the end of the three-year period.

In the first six months of 2012, the Company granted PSUs. The 2012 grant vests after a three-year period based on the Company’s total stockholder return relative to the performance of the components of the S&P 500 Index for the respective three-year period. The amount of PSUs earned will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance.

For all PSUs, respectively during the three and six months ended June 30, 2012, the Company recognized income of $2 million and expense of $6 million. During the three and six months ended June 30, 2011, the Company recognized expense of $4 million and $11 million, respectively, related to PSUs. As of June 30, 2012, there was $12 million of total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 2.02 years.

2012 Grant

For the 2012 grant, the portion of the PSUs settled in cash will be revalued every reporting period until the award is fully vested. As a result, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. For the six-month period ended June 30, 2012, the Company estimated the fair value of the PSUs granted using a Monte Carlo simulation that used various assumptions that include expected volatility of 38.3%, a risk free rate of 0.4% and an expected term of 2.51 years. Expected volatility was based on a benchmark study of our peers. The risk-free interest rate was based on zero coupon United States Treasury bills at the time of revaluation. The expected term represents the period beginning June 30, 2012, to the end of the three-year performance period.

For the 2012 grant, the fair value of the portion of PSUs settled in stock was estimated at the grant date using a Monte Carlo simulation that used various assumptions that include expected volatility of 48.2%, a risk free interest rate of 0.3% and an expected term of 2.91 years. Expected volatility was based on a benchmark study of ourselves and our peers. The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three-year performance period.

14. EARNINGS (LOSS) PER SHARE (continued)

On April 19, 2012, the Company approved a new share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “2012 Repurchase Program”). The 2012 Repurchase Program is in addition to the share buy-back program announced August 4, 2010, (the “2010 Repurchase Program” and collectively with the 2012 Repurchase Program, the “Repurchase Programs”). The Repurchase Programs authorize the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company’s discretion. During the six months ended June 30, 2012, 2.6 million shares were repurchased under the Repurchase Programs. As of June 30, 2012, 11.1 million shares remain available for repurchase under the Repurchase Programs.

For the three and six months ended June 30, 2012, the number of shares used in the calculation of diluted earnings per share did not include 0.0 and 0.5 million non-vested restricted shares, 0.4 and 0.7 million options to purchase common stock, 17.5 million common equivalent shares from Series A Warrants or 7.8 million common equivalent shares from Series B Warrants due to their anti-dilutive effect.

For the three and six months ended June 30, 2011, the number of shares used in the calculation of diluted earnings per share did not include 0.4 million options to purchase common stock, 17.5 million common equivalent shares from Series A Warrants or 7.8 million common equivalent shares from Series B Warrants due to their anti-dilutive effect.

15. FAIR VALUE MEASUREMENT

Items Measured at Fair Value

The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories:

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 table summarizes the fair values, and levels within the fair value hierarchy in which the fair value measurements fall, for assets and liabilities measured on a recurring basis as of June 30, 2012 (in millions):

15. FAIR VALUE MEASUREMENT (continued)

Cash equivalents and term deposits, by their nature, utilize Level 1 inputs in determining fair value. The term deposits are included in other current assets on the Consolidated Balance Sheets. The Company measures the value of its natural gas hedge contracts and foreign currency forward contracts using Level 2 inputs. The fair value of the Company’s natural gas hedges is determined by a mark to market valuation based on forward curves using observable market prices and the fair value of its foreign currency forward contracts is determined using observable market transactions in over-the-counter markets.

The fair value has been calculated using the expected future cash flows discounted at market interest rates. The Company believes that the carrying amounts reasonably approximate the fair values of long-term notes receivable. Long-term notes receivable were $48 million as of June 30, 2012.

Long-term debt

The fair value of the Company’s long-term debt has been calculated based on quoted market prices for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities.

As of June 30, 2012, the Company’s 6.50% senior notes due 2016 were trading at approximately 112% of par value, the 7.00% senior notes due 2036 were trading at approximately 106% of par value and the 9.00% senior notes due 2019 were trading at approximately 127% of par value.

At June 30, 2012, the Company determined that the book value of the remaining long-term debt instruments approximates market value. This approach, using level 1 inputs and utilizing indicative market rates for a new debt issuance, approximated the fair value of the remaining long-term debt at $643 million.

16. INCOME TAXES

Income tax expense for the three and six months ended June 30, 2012, was $17 million and $22 million, respectively. For the second quarter and year-to-date 2012, the Company’s effective tax rate was 30% and 129%, respectively. For both periods, the difference between the effective tax rate and the statutory rate of 35% is primarily attributable to the tax accounting treatment related to various locations which are currently in a loss position and various tax planning initiatives.

Income tax expense for the three and six months ended June 30, 2011, was $29 million and $40 million, respectively. The Company’s effective tax rate for the second quarter 2011 was 27%. Excluding approximately $8 million of benefit related to the reversal of a valuation allowance in a foreign location and other discrete items during the first six months of 2011, the Company’s effective tax would have been 34%. The difference between the effective tax rate for both the quarter and the year-to-date and the statutory rate of 35% is primarily attributable to the benefit of lower foreign tax rates and various tax planning initiatives.

17. CONDENSED CONSOLIDATING FINANCIAL STATEMENTS

The following Condensed Consolidating Financial Statements present the financial information required with respect to those entities which guarantee certain of the Company’s debt. The Condensed Consolidating Financial Statements are presented on the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the Company’s share of the subsidiaries’ cumulative results of operations, capital contributions, distributions and other equity changes. The principal elimination entries eliminate investment in subsidiaries and intercompany balances and transactions.

Guarantor and Nonguarantor Financial Statements

The Senior Notes and the Senior Revolving Credit Facility are guaranteed, fully, unconditionally and jointly and severally, by each of Owens Corning’s current and future 100% owned material domestic subsidiaries that is a borrower or a guarantor under Owens Corning’s Credit Agreement, which permits changes to the named guarantors in certain situations (collectively, the “Guarantor Subsidiaries”). The remaining subsidiaries have not guaranteed the Senior Notes and the Senior Revolving Credit Facility (collectively, the “Nonguarantor Subsidiaries”).

During the fourth quarter of 2011, the Company discovered certain items were not appropriately classified between the Parent and Guarantor Subsidiaries within the Condensed Consolidating Financial Statements. The effect of correcting these classifications was not material to the consolidating financial information. The Company has revised its 2011 quarterly consolidating information for comparison with 2012.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand Owens Corning, our operations and our present business environment. MD&A is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and the accompanying Notes thereto contained in this report. Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning.

GENERAL

Owens Corning is a leading global producer of glass fiber reinforcements and other materials for composites and of residential and commercial building materials. The Company’s business operations fall within two reportable segments, Composites and Building Materials. Composites includes our Reinforcements and Downstream businesses. Building Materials includes our Insulation and Roofing businesses. Through these lines of business, we manufacture and sell products worldwide. We maintain leading market positions in many of our major product categories.

EXECUTIVE OVERVIEW

We reported $85 million in earnings before interest and taxes (“EBIT”) for the second quarter 2012. We generated $117 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) for the second-quarter 2012. Our Building Materials segment grew second quarter EBIT by $4 million, whereas EBIT in our Composites segment declined by $21 million compared to the same period in 2011. We are on track with the repositioning of our European assets and recorded $32 million of charges during the second quarter related to these actions. See below for further information regarding adjusted EBIT, including the reconciliation to net earnings attributable to Owens Corning.

In our Composites segment, EBIT in the second quarter 2012 was $34 million compared to $55 million in the same period in 2011 driven by inflation, slightly lower selling prices and lower production volumes.

In our Building Materials segment, EBIT in the second quarter 2012 was $107 million, compared to $103 million in the same period in 2011. In our Roofing business, EBIT declined $18 million on lower sales volumes. Higher selling prices were more than offset by raw material inflation, primarily asphalt. Our Insulation business narrowed EBIT losses by $22 million compared to the same period in 2011, driven by manufacturing productivity and improved capacity utilization.

We maintain a strong balance sheet with ample liquidity. We have access to an $800 million senior revolving credit facility with a July 2016 maturity date and a $250 million receivables securitization facility with a December 2014 maturity date. We have no other significant debt maturities before 2016.

We repurchased 2.6 million shares of the Company’s common stock for $76 million during the second quarter of 2012 under previously announced repurchase programs. As of June 30, 2012, 11.1 million shares remain available for repurchase under the authorized programs.

Due to the normal seasonality of our business, we typically have negative cash flow from operations for the first half of the year. Year-to-date 2012, we used $40 million in cash flow from operating activities compared to a use of $134 million in the same period of 2011. This improvement was primarily from reductions in working capital and lower contributions to our pension plans.

The Consolidated Results discussion below provides a summary of our results and the trends affecting our business, and should be read in conjunction with the more detailed Segment Results discussion that follows.

NET SALES

Net sales were $60 million lower in the second quarter of 2012 compared to the same period in 2011 mainly due to lower sales volumes in our Building Materials segment and the unfavorable impact of translating sales denominated in foreign currencies into United States dollars in our Composites segment. For the year-to-date comparison, net sales were $48 million higher mainly due to higher sales volumes in our Insulation business, which were partially offset by the unfavorable impact of translating sales denominated in foreign currencies into United States dollars in our Composites segment.

GROSS MARGIN

Gross margin as a percentage of sales was lower in both the second-quarter and year-to-date comparisons due primarily to a $30 million and $51 million charge resulting from our European restructuring actions, respectively, both of which are reflected in cost of sales. Also contributing to the change in gross margin for both periods was a decrease in gross margin in our Composites segment. In our Building Materials segment, gross margin was relatively flat compared to the same period in 2011.

CHARGES RELATED TO COST REDUCTION ACTIONS

During the first quarter of 2012, we took actions to improve the competitive position of our global manufacturing network through the closure or optimization of certain facilities in Europe. As a result of these actions, in addition to the charges recorded in cost of sales, we recognized severance charges of $2 million in the second quarter and $36 million year-to-date 2012. The total charges related to cost reduction actions and related items for the three and six months ended June 30, 2012, were $32 million and $87 million, respectively. No charges were taken in 2011 as a result of cost reduction actions.

EARNINGS BEFORE INTEREST AND TAXES

In addition to the items noted above, general corporate expense and other increased by $2 million in the second quarter of 2012, compared to the same period in 2011. For the year-to-date comparison, general corporate expense and other increased by $14 million, compared to the same period in 2011, on higher non-service pension costs and reduced foreign currency gains. We also recorded gains from the sale of precious metals during the first six months of 2011, which are reflected in other (income) expense.

INTEREST EXPENSE, NET

Year-to-date 2012 interest expense was higher than in 2011 due primarily to higher average borrowing levels.

- 40 -

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

INCOME TAX EXPENSE

The effective tax rate for the second quarter 2012 was 30 percent. We estimate that the effective tax rate on adjusted earnings for the full year 2012 will be about 25 percent. The difference between the effective tax rate of 25 percent and the statutory rate of 35 percent is primarily attributable to lower foreign tax rates and various tax planning initiatives.

Adjusted Earnings Before Interest and Taxes (“Adjusted EBIT”)

Adjusted EBIT excludes certain significant items that management does not allocate to our segment results because it believes they are not a result of the Company’s current operations. Adjusted EBIT is used internally by the Company for various purposes, including reporting results of operations to the Board of Directors of the Company, analysis of performance and related employee compensation measures. Although management believes that these adjustments result in a measure that provides a useful representation of our operational performance, the adjusted measure should not be considered in isolation or as a substitute for net earnings attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

Adjusting items are shown in the table below (in millions), which are related to our European restrucuturing actions:

Segment Results

Earnings before interest and taxes (“EBIT”) by segment consists of net sales less related costs and expenses and are presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBIT for our reportable segments and are included in the Corporate, Other and Eliminations category, which is presented following the discussion of our reportable segments.

Composites

The table below provides a summary of net sales, EBIT and depreciation and amortization expense for the Composites segment (in millions):

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Net sales	$	498		$	529		$	974		$	1,021

EBIT as a % of net sales		7	%		10	%		6	%		10	%
Depreciation and amortization expense	$	31		$	32		$	61		$	66

NET SALES

Second quarter and year-to-date net sales in our Composites business decreased $31 million and $47 million, respectively, compared to the same periods in 2011. For both the second-quarter and year-to-date comparisons, net sales were unfavorably impacted by approximately $25 million and $40 million, respectively, as a result of translating sales denominated in foreign currencies into United States dollars and approximately $10 million and $20 million, respectively, from the May 2011 divestiture of our glass reinforcements facility in Capivari, Brazil. Sales volumes, excluding Capivari, increased about two percent in both periods compared to the prior year, supported by growth in global industrial production and glass reinforcements demand, partially offset by slightly lower selling prices.

EBIT

EBIT in our Composites business decreased $21 million and $46 million, respectively, for the second quarter and year-to-date 2012 compared to the same periods in 2011. For the quarter, the decline in EBIT was driven equally by inflation costs, slightly lower selling prices and the impact of rebalancing supply and demand in our manufacturing network. For the year-to-date comparison, about $30 million of the decline in EBIT was driven equally by inflation costs and slightly lower selling prices. In addition, we recorded a benefit from the resolution of an acquisition liability in the first quarter of 2011.

OUTLOOK

Global glass reinforcements market demand has grown on average with global industrial production and we believe this relationship will continue. In 2011, global glass reinforcements market demand grew less than the historical average of five percent driven by weaknesses in European industrial production. Based on the outlook for global industrial production, we expect the market will continue to grow in 2012, although again at a rate below the five percent historical average. As previously announced, we took actions in the first quarter of 2012 to close or optimize certain facilities in Europe and other actions that align with our objectives in the region to improve our competiveness. We anticipate incurring charges of approximately $130 million related to these actions in 2012 and 2013. For the year-to-date, we recognized approximately $87 million in charges associated with these actions.

Based on current market outlook for global industrial production growth, together with actions we initiated during the first quarter to improve our competitive position, we expect stronger financial performance during the second half of 2012. Our previously announced capacity expansions in Russia and Mexico will be completed and operational during 2012. These low-cost facilities will contribute to our global network in the second half of 2012.

We expect inventory to be at target levels by the end of 2012. A significant portion of the manufacturing actions to reduce inventory will take effect in the third quarter of 2012, resulting in lower capacity utilization in this period.

NET SALES

Net sales in our Building Materials segment were $26 million lower in the second quarter 2012 and $107 million higher for year-to-date 2012 compared to the same periods in 2011. For the quarter, net sales decreased due primarily to lower sales volumes in our Roofing business. For the year-to-date comparison, the increase in net sales was primarily the result of higher sales volumes within our Insulation business and higher selling prices within our Roofing business.

In our Roofing business, net sales were $40 million lower in the second quarter of 2012 and $52 million higher for year-to-date 2012, compared to the same periods in 2011. For the second quarter, lower sales volumes drove about a 10 percent decrease in net sales. The impact of lower sales volumes was partially offset by higher selling prices and favorable mix. Quarter-over-quarter comparability was also impacted by the significant storm activity we saw in the second quarter 2011 and the bringing forward of demand into the first quarter 2012 buy season. For the year-to-date comparison, the increase in net sales was about equally driven by higher selling prices and favorable mix on relatively flat sales volumes.

In our Insulation business, net sales were $14 million higher in the second quarter 2012 and $55 million higher for year-to-date 2012 compared to the same periods in 2011. Sales volumes were higher by approximately $20 million in the second quarter and approximately $80 million year-to-date 2012. For both periods, the benefit of higher sales volumes was partially offset by unfavorable mix. Our experience shows that our residential insulation demand lags United States housing starts by approximately three months. Lagged United States housing starts were up 23 percent for the quarter and 24 percent on a year-over-year basis.

EBIT

EBIT for our Building Materials segment increased $4 million and $23 million in the second quarter and year-to-date 2012, compared to the same periods in 2011, respectively. Our Insulation business narrowed EBIT losses on favorable manufacturing productivity and improved capacity utilization.

In our Roofing business, EBIT decreased $18 million and $12 million in the second quarter and year-to-date 2012 compared to the same periods in 2011, respectively. For the quarter, the decrease in EBIT was driven by lower sales volumes. Higher

- 43 -

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

selling prices and favorable mix were offset by raw material inflation, primarily asphalt. For the year-to-date comparison, higher selling prices and favorable mix were more than offset by raw material inflation, primarily asphalt, on relatively flat sales volumes.

In our Insulation business, we narrowed EBIT losses by $22 million and $35 million in the second quarter and year-to-date 2012 compared to the same periods in 2011, respectively. For the second quarter, manufacturing productivity and improved capacity utilization contributed equally to the improvement in EBIT. Slightly higher selling prices were offset by mix. For the year-to-date comparison, the improvement in EBIT was about equally driven by higher sales volumes, manufacturing productivity and improved capacity utilization.

OUTLOOK

While the recent information on United States housing starts has been positive, the timing and pace of recovery remains uncertain.

In our Roofing business, we expect the factors that have driven margins in recent years will continue to deliver profitability. Uncertainties that may impact our Roofing margins include competitive pricing pressure and the cost and availability of raw materials, particularly asphalt.

In our Insulation business, we expect improved financial performance in the second half of 2012 on higher sales volumes and improved unit margins. We believe the geographic, product and channel mix of our portfolio may continue to moderate the impact of demand-driven weakness associated with United States new construction. Should the recovery of new construction be sooner and faster than anticipated, we are prepared to respond to increased demand by bringing additional production capacity back on line.

Corporate, Other and Eliminations

The table below provides a summary of EBIT and depreciation and amortization expense for the Corporate, Other and Eliminations category (in millions):

	Three Months Ended June 30,						Six Months Ended June 30,

EBIT	$	(56	)	$	(23	)	$	(140	)	$	(40	)
Depreciation and amortization	$	24		$	12		$	49		$	19

EBIT

In Corporate, Other and Eliminations, EBIT losses for the second quarter and year-to-date 2012 were $56 million and $140 million, respectively. For the second quarter and year-to-date periods, we recorded $32 million and $87 million in charges related to cost reduction actions and related items, respectively, to improve our competitive position in Europe, which consist primarily of severance and accelerated depreciation charges. The 2011 charges related to cost reduction actions and related items were the result of evaluating market conditions in our Insulation business and our decision to exit certain non-core lines of our business. The resultant charges primarily consist of contract provisions and asset impairment charges. In May 2011, we recorded a $16 million gain on the sale of our glass reinforcements facility in Capivari, Brazil.

For the second quarter of 2012, general corporate expense and other was $2 million higher compared to the same period in 2011, due primarily to higher non-service pension costs. For the year-to-date 2012 comparison, general corporate expense and other increased $14 million, compared to the same period in 2011. Incentive compensation expense decreased by

- 44 -

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

approximately $6 million, which was more than offset by higher non-service pension costs of approximately $6 million and reduced foreign currency gains of approximately $6 million. In addition, for the second quarter and year-to-date periods 2011, we recognized gains from the sale of precious metal used in production tooling.

Depreciation and amortization increased $12 million for the second quarter and $30 million year-to-date 2012, compared to the same period in 2011. For both periods, the increase was due primarily to recognition of accelerated depreciation related to our European restructuring plan initiated during the first quarter of 2012.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS

Liquidity

We have an $800 million senior revolving credit facility and a $250 million receivables securitization facility, which serve as our primary sources of liquidity. Our senior revolving credit facility matures in July 2016, and our receivables securitization facility matures in December 2014. We have no other significant debt maturities before 2016. As of June 30, 2012, the receivables securitization facility was fully utilized and we had $426 million available on the senior revolving credit facility. As of June 30, 2012, we had $ 2.2 billion of total debt and cash-on-hand of $54 million.

Cash and cash equivalents held by foreign subsidiaries may be subject to U.S. income taxation upon repatriation to the U.S. We do not provide for U.S. income taxes on the undistributed earnings of these subsidiaries as earnings are reinvested and, in the opinion of management, will continue to be reinvested indefinitely outside of the U.S. As of June 30, 2012, and December 31, 2011, we had approximately $46 million in cash and cash equivalents in certain of our foreign subsidiaries where we consider undistributed earnings for these foreign subsidiaries to be permanently reinvested.

We expect that our cash on hand, coupled with future cash flows from operations and other available sources of liquidity, including our senior revolving credit facility, will provide ample liquidity to enable us to meet our cash requirements. Our anticipated uses of cash include capital expenditures, working capital needs, pension contributions, meeting financial obligations and reducing outstanding amounts under the senior revolving credit facility and receivables securitization facility. We have outstanding share repurchase authorizations and will evaluate and consider repurchasing shares of our common stock, as well as strategic acquisitions, divestitures, joint ventures and other transactions to create stockholder value and enhance financial performance. Such transactions may require cash expenditures beyond current sources of liquidity or generate proceeds.

We are closely monitoring the economic environment for the potential impact of changes in the operating conditions of our customers on our operating results. To date, changes in the operating conditions of our customers have not had a material adverse impact on our operating results; however, it is possible that we could experience material losses in the future if current economic conditions worsen.

The credit agreement applicable to our senior revolving credit facility and the receivables securitization facility contain various covenants that we believe are usual and customary for agreements of these types. The senior revolving credit facility includes a maximum allowed leverage ratio and a minimum required interest expense coverage ratio. We were well within compliance with these covenants as of June 30, 2012.

Cash Flows

The following table presents a summary of our cash balance and cash flows (in millions):

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Cash balance	$	54		$	51		$	54		$	51

- 45 -

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Operating activities: For year-to-date 2012, we used $40 million of cash for operating activities compared to $134 million in the same period in 2011. Cash used for both working capital requirements and pension contributions were lower in 2012 than in 2011.

Investing activities: For year-to-date 2012, cash flow used for investing activities increased $21 million compared to the same period in 2011. In 2012, we spent $47 million less in additions to plant and equipment. In 2011, we received $55 million of proceeds from the sale of our glass reinforcements facility in Capivari, Brazil.

Financing activities: Cash provided by financing activities was $66 million lower year-to-date 2012, compared to the same period in 2011. The decrease in cash provided by financing was due to fewer cash needs for working capital and additional share repurchases during 2012 compared to 2011.

2012 Investments

Capital Expenditures: The Company will continue a balanced approach to the use of its cash flow. Operational cash flow will be used to fund the Company’s growth and innovation. Capital expenditures in 2012 are expected to be approximately $340 million, which will be higher than depreciation and amortization, excluding the impact of restructuring actions. The Company will also continue to evaluate projects and acquisitions that provide opportunities for growth in our businesses and invest in them when they meet our strategic and financial criteria.

Tax Net Operating Losses

Upon emergence and subsequent distribution of contingent stock and cash in January 2007, we generated a significant United States federal tax net operating loss of approximately $3 billion. As of June 30, 2012, our federal tax net operating losses remaining were $2.2 billion. Our net operating losses are subject to the limitations imposed under section 382 of the Internal Revenue Code. These limits are triggered when a change in control occurs, and are computed based upon several variable factors including the share price of the Company’s common stock on the date of the change in control. A change in control is generally defined as a cumulative change of 50 percent or more in the ownership positions of certain stockholders during a rolling three-year period. Our initial three-year period for measuring an ownership change started at October 31, 2006.

In addition to the United States net operating losses described above, we have net operating losses in various state and foreign jurisdictions, which totaled $3.3 billion and $633 million, respectively, as of December 31, 2011. Our ability to utilize these net operating losses may be limited as a result of certain events, such as insufficient future taxable income prior to expiration of the net operating losses or changes in tax legislation. Should we determine that it is likely that our recorded net operating loss benefits are not realizable, we would be required to reduce the net operating loss tax benefits reflected on our Consolidated Financial Statements to the net realizable amount by establishing an accounting valuation allowance and recording a corresponding charge to current earnings. To date, we have recorded valuation allowances against certain of these deferred tax assets.

Pension Contributions

The Company has several defined-benefit pension plans. The Company made cash contributions of approximately $30 million and $90 million to the plans during the six months ended June 30, 2012 and 2011, respectively. In 2011, trends in interest rates led to increased pension contributions required to maintain our funded status. The effect of new legislation passed by United States Congress in June 2012 reduced our previously expected cash contributions by approximately $13 million during 2012. The Company now expects to contribute $57 million in cash to its global pension plans during 2012. See Note 11 for further discussion. Actual contributions to the plans may change as a result of several factors, including changes in laws that impact funding requirements. The ultimate cash flow impact to the Company, if any, of the pension plan liability and the timing of any such impact will depend on numerous variables, including future changes in actuarial assumptions, legislative changes to pension funding laws and market conditions.

Derivatives

In the normal course of business, the Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates and interest rates. To mitigate some of the near-term volatility in our earnings and cash flows, we use financial and derivative instruments to hedge certain exposures, principally currency- and energy-related. The

- 46 -

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Company does not enter into such transactions for trading purposes. Our current hedging practice is to hedge a variable percentage of certain energy and energy-related exposures. Going forward, the results of our hedging practice could be positive, neutral or negative in any period depending on price changes in the hedged exposures, and will tend to mitigate near-term volatility in the exposures hedged. The practice is neither intended nor expected to mitigate longer term exposures. See Note 4 to the Consolidated Financial Statements for further discussion.

Our current practice is to manage our interest rate exposure by balancing the mixture of our fixed- and variable-rate instruments. We utilize, among other strategies, interest rate swaps to achieve this balance in interest rate exposures. There are currently no derivatives outstanding which are related to balancing our fixed- and variable-rate instruments.

Fair Value Measurement

Items Measured at Fair Value

The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories:

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.

Off-Balance-Sheet Arrangements

The Company has entered into limited off-balance-sheet arrangements, as defined under Securities and Exchange Commission rules, in the ordinary course of business. The Company does not believe these arrangements will have a material effect on the Company’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Contractual Obligations

In the normal course of business, we enter into contractual obligations to make payments to third parties. During the six months ended June 30, 2012, there were no material changes to such contractual obligations outside the ordinary course of our business.

SAFETY

Working safely is a condition of employment at Owens Corning. We believe this organization-wide expectation provides for a safer work environment for employees, improves our manufacturing processes, reduces our costs and enhances our reputation. Furthermore, striving to be a world-class leader in safety provides a platform for all employees to understand and apply the resolve necessary to be a high-performing global organization. We measure our progress on safety based on Recordable Incidence Rate (“RIR”) as defined by the United States Department of Labor, Bureau of Labor Statistics. Owens Corning’s RIR was approximately 13 percent higher at June 30, 2012, representing a year-to-date decline in comparison to the company’s full-year 2011 performance.

ENVIRONMENTAL MATTERS

We have been deemed by the Environmental Protection Agency (“EPA”) to be a Potentially Responsible Party (“PRP”) with respect to certain sites under the Comprehensive Environmental Response Compensation and Liability Act. We have also been deemed a PRP under similar state or local laws and in other instances other PRPs have brought suits against us as a PRP for contribution under such federal, state, or local laws. At June 30, 2012, we had environmental remediation liabilities as a PRP at 19 sites where we have a continuing legal obligation to either complete remedial actions or contribute to the completion of remedial actions as part of a group of PRPs. For these sites we estimate a reserve to reflect environmental liabilities that have been asserted or are probable of assertion, in which liabilities are probable and reasonably estimable. At June 30, 2012, our reserve for such liabilities was $8 million.

Income Tax Disclosure [Abstract]

INCOME TAXES

16.       INCOME TAXES

Income tax expense for the three and six months ended June 30, 2012,was $17million and $22million, respectively. For the second quarter and year-to-date 2012, the Company's effective tax rate was 30% and 129%, respectively. For both periods, the difference between the effective tax rate and the statutory rate of 35% is primarily attributable to the tax accounting treatment related to various locations which are currently in a loss position and various tax planning initiatives.

Income tax expense for the three and six months ended June 30, 2011, was $29 million and $40 million, respectively. The Company's effective tax rate for the second quarter 2011 was 27%. Excluding approximately $8 million of benefit related to the reversal of a valuation allowance in a foreign location and other discrete items during the first six months of 2011, the Company's effective tax would have been 34%. The difference between the effective tax rate for both the quarter and the year-to-date and the statutory rate of 35% is primarily attributable to the benefit of lower foreign tax rates and various tax planning initiatives.

PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

11.       PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee's years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. The unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits.

The following tables provide information regarding pension expense recognized (in millions):

During July of 2012, Congress passed the “Moving Ahead for Progress in the 21st Century Act,” which included pension funding stabilization provisions. The measure, which is designed to stabilize the discount rate used to determine funding requirements from the effects of interest rate volatility, reduces the Company's United States Pension Plan contributions by approximately $13 million during 2012.

The Company now expects to contribute approximately $36 million in cash to the United States Pension Plans and another $21 million to non-United States plans during 2012. The Company made cash contributions of approximately $30 million to the plans during the six months ended June 30, 2012.

Postemployment and Postretirement Benefits Other than Pension Plans

The Company maintains healthcare and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

The following table provides the components of net periodic benefit cost for aggregated United States and non-United States Plans for the periods indicated (in millions):

CONTINGENT LIABILITIES AND OTHER MATTERS TEXT BLOCK

12.CONTINGENT LIABILITIES AND OTHER MATTERS

Litigation

The Company is involved in various legal proceedings relating to employment, product liability and other matters. The Company regularly reviews the status of these proceedings along with legal counsel. Liabilities for such items are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company's operations or financial condition taken as a whole.

Environmental Matters

We have been deemed by the Environmental Protection Agency (“EPA”) to be a Potentially Responsible Party (“PRP”) with respect to certain sites under the Comprehensive Environmental Response Compensation and Liability Act. We have also been deemed a PRP under similar state or local laws and in other instances other PRPs have brought suits against us as a PRP for contribution under such federal, state, or local laws. At June 30, 2012, we had environmental remediation liabilities as a PRP at 19 sites where we have a continuing legal obligation to either complete remedial actions or contribute to the completion of remedial actions as part of a group of PRPs. For these sites we estimate a reserve to reflect environmental liabilities that have been asserted or are probable of assertion, in which liabilities are probable and reasonably estimable. At June 30, 2012, our reserve for such liabilities was $8 million.

Other Items

On December 17, 2010, the French tax authorities made a claim in the amount of approximately 123 million Euros against a subsidiary the Company acquired as part of the acquisition of Saint-Gobain's reinforcement and composite fabrics business in 2007 (the “2007 Acquisition”). The claim relates to transactions that occurred prior to the closing of the 2007 Acquisition. Pursuant to the purchase agreement governing the 2007 Acquisition, Saint-Gobain is required to indemnify Owens Corning and its subsidiaries for pre-closing tax claims and related damages, attorney fees and expenses. On July 17, 2012, the Company received a communication from the French tax authorities rescinding their original claim against the subsidiary of the Company. The Company does not expect any further inquiries regarding the claim.

Other Intangible Assets

The Company expects the ongoing amortization expense for amortizable intangible assets to be approximately $21 million in each of the next five fiscal years. The Company's future cash flows are not materially impacted by its ability to extend or renew agreements related to our amortizable intangible assets.

Goodwill

The Company tests goodwill and indefinite-lived intangible assets for impairment during the fourth quarter of each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying amount.No testing was deemed necessary in the second quarter of 2012.

17.       CONDENSED CONSOLIDATING FINANCIAL STATEMENTS

The following Condensed Consolidating Financial Statements present the financial information required with respect to those entities which guarantee certain of the Company's debt. The Condensed Consolidating Financial Statements are presented on the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the Company's share of the subsidiaries' cumulative results of operations, capital contributions, distributions and other equity changes. The principal elimination entries eliminate investment in subsidiaries and intercompany balances and transactions.

Guarantor and Nonguarantor Financial Statements

The Senior Notesand the Senior Revolving Credit Facility are guaranteed, fully, unconditionally and jointly and severally, by each of Owens Corning's current and future 100% owned material domestic subsidiaries that is a borrower or a guarantor under Owens Corning's Credit Agreement, which permits changes to the named guarantors in certain situations (collectively, the “Guarantor Subsidiaries”). The remaining subsidiaries have not guaranteed the Senior Notes and the Senior Revolving Credit Facility (collectively, the “Nonguarantor Subsidiaries”).

During the fourth quarter of 2011, the Company discovered certain items were not appropriately classified between the Parent and Guarantor Subsidiaries within the Condensed Consolidating Financial Statements. The effect of correcting these classifications was not material to the consolidating financial information. The Company has revised its 2011 quarterly consolidating information for comparison with 2012.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK COMPENSATION

13.       STOCK COMPENSATION

2010 Stock Plan

On April 22, 2010, the Company's stockholders approved the Owens Corning 2010 Stock Plan (the “2010 Stock Plan”), which replaced the Owens Corning 2006 Stock Plan (the “2006 Stock Plan”), as amended and restated. The 2010 Stock Plan authorizes grants of stock options, stock appreciation rights, stock awards, restricted stock awards, restricted stock units, bonus stock awards and performance stock awards. Such shares of common stock include shares that were available but not granted, or which were granted but were not issued or delivered due to expiration, termination, cancellation or forfeiture of such awards. At June 30, 2012, the number of shares remaining available under the 2010 Stock Plan for all stock awards was2.6 million.

Stock Options

The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four-year vesting period. In general, the exercise price of each option awarded was equal to the market price of the Company's common stock on the date of grant and an option's maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers.

During the six months ended June 30, 2012, 409,700 stock options were granted with a weighted-average grant date fair value of $15.27. Assumptions used in the Company's Black-Scholes valuation model to estimate the grant date fair value were expected volatility of 45.8%, expected dividends of 0%, expected term of 6.26 years and a risk-free interest rate of 1.1%.

During the three and six months ended June 30, 2012, the Company recognized expense of $1 millionand $2 million respectively, related to the Company's stock options. During the three and six months ended June 30, 2011, the Company recognized expense of $1million and $2 million respectively, related to the Company's stock options. As of June 30, 2012, there was $11 million of total unrecognized compensation cost related to stock options. That cost is expected to be recognized over a weighted-average period of 2.86 years. The total aggregate intrinsic value of options outstanding as of June 30, 2012and 2011 was $11 million and$37 million.

The following table summarizes the Company's stock option activity for the six months ended June 30, 2012:
									Six Months Ended
									June 30, 2012
									Number of Options	Weighted-Average Exercise Price
Beginning Balance									3,293,545	$	26.26

Exercised									(193,100)		23.86
Forfeited									(32,825)		28.98
Ending Balance									3,477,320	$	27.25
The following table summarizes information about the Company's options outstanding and exercisable:
	Options Outstanding						Options Exercisable
		Weighted-Average							Weighted-Average
Range of Exercise Prices	Options Outstanding	Remaining Contractual Life	Exercise Price		Number Exercisable at June 30, 2012			Remaining Contractual Life		Exercise Price
$7.57- $34.94	3,477,320	6.24	$	27.25		2,397,803			5.25	$	26.52

Restricted Stock Awards and Restricted Stock Units

The Company has granted restricted stock awards and restricted stock units (collectively referred to as “restricted stock”) under its stockholder approved stock plans. Compensation expense for restricted stock is measured based on the market price of the stock at date of grant and is recognized on a straight-line basis over the four-year vesting period. Stock restrictions are subject to alternate vesting plans for death, disability, approved early retirement and involuntary termination, over various periods ending in 2015.

During the three and six months ended June 30, 2012, the Company recognized expense of $4 millionand $8 million respectively, related to the Company's restricted stock. During the three and six months ended June 30, 2011, the Company recognized expense of $3million and $6 million respectively. As of June 30, 2012, there was $30 million of total unrecognized compensation cost related to restricted stock. That cost is expected to be recognized over a weighted-average period of 2.96 years. The total fair value of shares vested during the six months ended June 30, 2012 and 2011 was $11 million and $8million, respectively.

A summary of the status of the Company's plans that had restricted stock issued as of June 30, 2012, and changes during the six months ended June 30, 2012, are presented below.

	Six Months Ended
	June 30, 2012
	Number of Shares	Weighted-Average Grant-Date Fair Value
Beginning Balance	1,941,742	$	19.74
Granted	593,945		33.45
Vested	(507,597)		22.14
Forfeited	(58,002)		27.86
Ending Balance	1,970,088	$	23.02

Performance Stock Awards and Performance Stock Units

The Company has granted performance stock awards and performance stock units (collectively referred to as “PSUs”) as a part of its long-term incentive plan, of which 50% will be settled in stock and 50% will be settled in cash. The number of the PSUs ultimately distributed is contingent on meeting various company or stockholder return goals.

Compensation expense for PSUs settled in stock is measured based on the grant date fair value and is recognized on a straight-line basis over the vesting period. Compensation expense for PSUs settled in cash is measured based on the fair value at the end of each quarter and is recognized on a straight-line basis over the vesting period. Vesting will be pro-rated based on the number of full months employed during the performance period in the case of death, disability, change in control or involuntary termination, and pro-rated awards earned will be paid at the end of the three-year period.

In the first six months of 2012, the Company granted PSUs. The 2012 grant vests after a three-year period based on the Company's total stockholder return relative to the performance of the components of the S&P 500 Index for the respective three-year period. The amount of PSUs earned will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance.

For all PSUs, respectively during the three and six months ended June 30, 2012,the Company recognized income of $2 millionand expense of $6 million. During the three and six months ended June 30, 2011, the Company recognized expense of $4 millionand $11 million, respectively, related to PSUs. As of June 30, 2012, there was $12 million of total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 2.02years.

2012 Grant

For the 2012 grant, the portion of the PSUs settled in cash will be revalued every reporting period until the award is fully vested. As a result, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. For the six-month period ended June 30, 2012, the Company estimated the fair value of the PSUs granted using a Monte Carlo simulation that used various assumptions that include expected volatility of 38.3%, a risk free rate of 0.4% and an expected term of 2.51 years. Expected volatility was based on a benchmark study of our peers. The risk-free interest rate was based on zero coupon United States Treasury bills at the time of revaluation. The expected term represents the period beginning June 30, 2012, to the end of the three-year performance period.

For the 2012 grant, the fair value of the portion of PSUs settled in stock was estimated at the grant date using a Monte Carlo simulation that used various assumptions that include expected volatility of 48.2%, a risk free interest rate of 0.3% and an expected term of 2.91 years. Expected volatility was based on a benchmark study of ourselves and our peers. The risk-free interest rate was based on zero coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three-year performance period.

A summary of the status of the Company’s plans that had issued PSUs as of June 30, 2012, and changes during the six months ended June 30, 2012, are presented below:
	Six Months Ended

2012 Cost Reduction Actions

As a result of evaluating market conditions, we took actions to improve the competitive position of our global manufacturing network by closing certain facilities in Europe along with other actions that align with our objectives in the region. In conjunction with these actions, the Company recorded $32 and $87 million in charges related to cost reduction actions and related items for the three and six months ended June 30, 2012, respectively; of which, $2 and $36 million is related to severance and is included in charges related to cost reduction actions on the Consolidated Statements of Earnings (Loss). The $30 and $51 million in other related charges, respectively, relates primarily to accelerated depreciation and is included in cost of sales on the Consolidated Statements of Earnings (Loss). Cash payments related to these activities will continue through 2015. The Company will continue to evaluate its global network to ensure it has the appropriate capacity to respond to future anticipated demand around the world.

Senior Notes

The Company issued $350 million of senior notes on June 3, 2009, and $1.2 billion of senior notes on October 31, 2006, which are collectively referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company.

The Senior Notes are fully and unconditionally guaranteed by each of the Company's current and future domestic subsidiaries that are a borrower or guarantor under the Company's Credit Agreement (as defined below). The guarantees are unsecured and rank equally in right of payment with all other existing and future senior unsecured indebtedness of the guarantors. The guarantees are effectively subordinated to existing and future secured debt of the guarantors to the extent of the assets securing that indebtedness.

The Company has the option to redeem all or part of the Senior Notes at any time at a “make whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of June 30, 2012.

In the fourth quarter of 2011, the Company terminated all existing interest rate swaps. The swaps were carried at fair value and recorded as other assets or liabilities, with a fair value adjustment to long-term debt on the Consolidated Balance Sheets. The fair value adjustment to debt will be amortized through 2016 as a reduction to interest expense in conjunction with the maturity date of the notes.

Senior Credit Facilities

On May 26, 2010, the Company entered into a credit agreement (the “Credit Agreement”) that established a new $800 million multi-currency senior revolving credit facility (the “Senior Revolving Credit Facility”). Also on May 26, 2010, the Company terminated the credit agreement dated as of October 31, 2006, which contained a $1.0 billion multi-currency senior revolving credit facility (the “Prior Revolving Credit Facility”) and a $600 million senior term loan facility.

The available principal amount of $800 million on the Senior Revolving Credit Facility includes both borrowings and letters of credit. The Company amended the Senior Revolving Credit Facility in July 2011 to extend the maturity to July 2016 and reduce the pricing. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate or LIBOR plus a spread.

The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a senior unsecured credit agreement. The Company was well within compliance with these covenants as of June 30, 2012.

The Company had $7 million and $42 million of letters of credit outstanding under the Senior Revolving Credit Facility at June 30, 2012 and December 31, 2011, respectively.

Receivables Securitization Facility

Included in long-term debt on the Consolidated Balance Sheets are amounts outstanding under a Receivable Purchase Agreement (the “RPA”). Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $250 million RPA with certain financial institutions.The securitization facility was amended in the fourth quarter of 2011 to extend maturity to December 2014. At June 30, 2012, the Company utilized the full amount permitted under the terms of the receivables securitization facility. The Company had $38million of letters of credit outstanding under the receivables securitization facility at June 30, 2012. There were no letters of credit outstanding under the receivables securitization facility at December 31, 2011.

The receivables securitization facility contains various covenants, including a maximum allowed leverage ratio and a minimum required interest expense coverage ratio that the Company believes are usual and customary for a securitization facility. The Company was well within compliance with these covenants as of June 30, 2012.

Owens Corning Receivables LLC's sole business consists of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers party to the RPA. Owens Corning Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of Owens Corning Receivables LLC's assets prior to any assets or value in Owens Corning Receivables LLC becoming available to Owens Corning Receivables LLC's equity holders. The assets of Owens Corning Receivables LLC are not available to pay creditors of the Company or any other affiliates of the Company or Owens Corning Sales, LLC.

Short-Term Debt

At June 30, 2012 and December 31, 2011, short-term borrowings were $24 million and $28 million, respectively. The short-term borrowings for both periods consisted of various operating lines of credit and working capital facilities. Certain of these borrowings are collateralized by receivables, inventories or property. The borrowing facilities are typically for one-year renewable terms. The weighted average interest rate on short-term borrowings was approximately 6.3% for June 30, 2012, and 7.4% for December 31, 2011.

15.       FAIR VALUE MEASUREMENT

Items Measured at Fair Value

The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories:

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 table summarizes the fair values, and levels within the fair value hierarchy in which the fair value measurements fall, for assets and liabilities measured on a recurring basis as of June 30, 2012 (in millions):
		Total Measured at Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Cash equivalents	$	9	$	9	$	-	$	-
Term deposits	$	6	$	6	$	-	$	-
Derivative assets	$	1	$	-	$	1	$	-
Total assets	$	16	$	15	$	1	$	-
Liabilities:
Derivative liabilities	$	(5)	$	-	$	(5)	$	-
Total liabilities	$	(5)	$	-	$	(5)	$	-

Cash equivalents and term deposits, by their nature, utilize Level 1 inputs in determining fair value. The term deposits are included in other current assets on the Consolidated Balance Sheets. The Company measures the value of its natural gas hedge contracts and foreign currency forward contracts using Level 2 inputs. The fair value of the Company's natural gas hedges is determined by a mark to market valuation based on forward curves using observable market prices and the fair value of its foreign currency forward contracts is determined using observable market transactions in over-the-counter markets.

Items Disclosed at Fair Value

Long-term notes receivable

The fair value has been calculated using the expected future cash flows discounted at market interest rates. The Company believes that the carrying amounts reasonably approximate the fair values of long-term notes receivable. Long-term notes receivable were $48million as of June 30, 2012.

Long-term debt

The fair value of the Company's long-term debt has been calculated based on quoted market prices for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities.

As of June 30, 2012, the Company's 6.50%senior notes due 2016 were trading at approximately 112% of par value, the 7.00% senior notes due 2036were trading at approximately 106% of par valueand the 9.00% senior notes due 2019 were trading at approximately 127% of par value.

At June 30, 2012, the Company determined that the book value of the remaining long-term debt instruments approximates market value. This approach, using level 1 inputs and utilizingindicative market rates for a new debt issuance, approximated the fair value of the remaining long-term debt at $643million.

DERIVATIVE FINANCIAL INSTRUMENTS

4.       DERIVATIVE FINANCIAL INSTRUMENTS

The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest rates in the normal course of business. The Company's risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes.

The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with counterparties generally contain right of offset provisions. These provisions effectively reduce the Company's exposure to credit risk in situations where the Company has gain and loss positions outstanding with a single counterparty. It is the Company's policy to offset on the Consolidated Balance Sheets the amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master netting agreement. As of June 30, 2012, and December 31, 2011,the Company did not have any amounts on deposit with any of its counterparties, nor did any of its counterparties have any amounts on deposit with the Company.

The following table presents the fair value of derivatives and hedging instruments and the respective location on the Consolidated Balance Sheets (in millions):

Cash Flow Hedges

The Company uses forward and swap contracts, which qualify as cash flow hedges, to manage forecasted exposure to natural gas prices. The effective portion of the change in the fair value of cash flow hedges is deferred in accumulated OCI and is subsequently recognized in cost of saleson the Consolidated Statements of Earnings (Loss) for commodity hedges, when the hedged item impacts earnings. Changes in the fair value of derivative assets and liabilities designated as hedging instruments are shown in other within operating activities on the Consolidated Statement of Cash Flows. Any portion of the change in fair value of derivatives designated as hedging instruments that is determined to be ineffective is recorded in other (income) expenses on the Consolidated Statements of Earnings (Loss).

The Company currently has natural gas derivatives designated as hedging instruments that mature within 15 months. The Company's policy is to hedge up to 75% of its total forecasted natural gas exposures for the next two months, up to 50% of its total forecasted natural gas exposures for the following four months, and lesser amounts for the remaining periods. Based on market conditions, approved variation from the standard policy may occur. The Company performs an analysis for effectiveness of its derivatives designated as hedging instruments at the end of each quarter based on the terms of the contract and the underlying item being hedged.

As of June 30, 2012, $2 million of losses included in accumulated OCI on the Consolidated Balance Sheets relate to contracts that will impact earnings during the next 12 months. Transactions and events that are expected to occur over the next 12 months that will necessitate recognizing these deferred amounts include the recognition of the hedged item through earnings.

Fair Value Hedges

The Company manages its interest rate exposure by balancing the mixture of its fixed and variable rate instruments through interest rate swaps.The swaps are carried at fair value and recorded as other assets or liabilities, with the offset to long-term debt on the Consolidated Balance Sheets. Changes in the fair value of these swaps and that of the related debt are recorded in interest expense, net on the Consolidated Statements of Earnings (Loss). In the fourth quarter of 2011, the Company terminated all existing interest rate swaps.

Other Derivatives

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses resulting from the changes in fair value of these instruments are recorded in other (income) expenses on the Consolidated Statements of Earnings (Loss).

As a result of first-quarter 2009 capacity curtailments taken at certain facilities, the normal purchase scope exception was no longer met for one of the Company's energy supply contracts. The contract was required to be marked to market each quarter through its termination date of January 31, 2012.

	Diluted	$	0.32	$	0.62	$	(0.06)	$	0.81

Basic earnings (loss) per share is calculated by dividing earnings attributable to Owens Corningby the weighted-average number of shares of the Company's common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.

On April 19, 2012, the Company approved a new share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company's outstanding common stock (the “2012 Repurchase Program”). The 2012 Repurchase Program is in addition to the share buy-back program announced August 4, 2010, (the “2010 Repurchase Program” and collectively with the 2012 Repurchase Program, the “Repurchase Programs”).The Repurchase Programs authorize the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company's discretion. During the six months ended June 30, 2012, 2.6 million shares were repurchased under the Repurchase Programs. As of June 30, 2012, 11.1million shares remain available for repurchase under the Repurchase Programs.

For the three and sixmonths ended June 30, 2012, the number of shares used in the calculation of diluted earnings per share did not include 0.0 and 0.5million non-vested restricted shares,0.4and 0.7 million options to purchase common stock,17.5 million common equivalent shares from Series A Warrants or7.8 million common equivalent shares from Series B Warrants due to their anti-dilutive effect.

For the three and six months ended June 30, 2011, the number of shares used in the calculation of diluted earningsper share did not include0.4 million options to purchase common stock,17.5 million common equivalent shares from Series A Warrants or7.8 million common equivalent shares from Series B Warrants due to their anti-dilutive effect.
