CORNING INCORPORATED AND SUBSIDIARY COMPANIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.      Significant Accounting Policies

Basis of Presentation

In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and subsidiary companies.

The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and in accordance with U.S. GAAP for interim financial information.  Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted or condensed.  These interim consolidated financial statements should be read in conjunction with Corning’s consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2011 (2011 Form 10-K).

The unaudited consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods presented.  All such adjustments are of a normal recurring nature.  The results for interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.

Other Income, Net

“Other income, net” in Corning’s consolidated statements of income includes the following (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Royalty income from Samsung Corning Precision	$	21	$	64	$	43	$	125
Foreign currency exchange and hedge gains/(losses), net		(1)		(7)		5		(17)
Net loss attributable to noncontrolling interests		1				3		1
Other, net		(13)		(14)		(14)		(39)
Total	$	8	$	43	$	37	$	70

New Accounting Standards

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.  The ASU 2011-11 amendments require companies to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position.  ASU 2011-11 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years beginning on or after January 1, 2013, and interim periods within those annual fiscal years.  Corning does not expect adoption of this standard to have a material impact on its consolidated financial condition.

-7-

2.      Commitments, Contingencies, and Guarantees

Asbestos Litigation

Pittsburgh Corning Corporation.  Corning and PPG Industries, Inc. (PPG) each own 50% of the capital stock of Pittsburgh Corning Corporation (PCC).  Over a period of more than two decades, PCC and several other defendants have been named in numerous lawsuits involving claims alleging personal injury from exposure to asbestos.  On April 16, 2000, PCC filed for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Western District of Pennsylvania.  Corning, with other relevant parties, has been involved in ongoing efforts to develop a Plan of Reorganization that would resolve the concerns and objections of the relevant parties.  A proposed PCC plan of reorganization (Amended PCC Plan) filed in the U.S. Bankruptcy Court for the Western District of Pennsylvania was not confirmed by the Court.  Further changes to the Amended PCC Plan are expected to be filed by August 20, 2012.  Corning also has an equity interest in Pittsburgh Corning Europe N.V. (PCE), a Belgian Corporation that is a component of the Company’s proposed resolution of the PCC asbestos litigation.  At June 30, 2012 and December 31, 2011, the fair value of PCE significantly exceeded its carrying value of $136 million and $138 million, respectively.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning.  Corning has recorded in its estimated asbestos litigation liability an additional $150 million for the approximately 9,900 current non-PCC cases alleging injuries from asbestos, and for any future non-PCC cases.  The liability for the Amended PCC Plan and the non-PCC asbestos claims was estimated to be $663 million at June 30, 2012, compared with an estimate of the liability of $657 million at December 31, 2011.  In the three and six months ended June 30, 2012, Corning recorded asbestos litigation expense of $5 million and $6 million, respectively.  In the three and six months ended June 30, 2011, Corning recorded asbestos litigation expense of $5 million and $10 million, respectively.  The entire obligation is classified as a non-current liability as installment payments for the cash portion of the obligation are not planned to commence until more than 12 months after the Amended PCC Plan becomes effective and the PCE portion of the obligation will be fulfilled through the direct contribution of Corning’s investment in PCE (currently recorded as a non-current other equity method investment).

Other Commitments and Contingencies

In the normal course of our business, we do not routinely provide significant third-party guarantees.  Generally, any third party guarantees provided by Corning are limited to certain financial guarantees including stand-by letters of credit and performance bonds, and the incurrence of contingent liabilities in the form of purchase price adjustments related to attainment of milestones.  When provided, these guarantees have various terms, and none of these guarantees are individually significant.

We have agreed to provide a credit facility to Dow Corning Corporation (Dow Corning).  The funding of the Dow Corning credit facility will be required only if Dow Corning is not otherwise able to meet its scheduled funding obligations in its confirmed Bankruptcy Plan.  We believe a significant majority of these guarantees and contingent liabilities will expire without being funded.

As of June 30, 2012 and December 31, 2011, contingent guarantees totaled a notional value of $140 million and $170 million, respectively.  We believe a significant majority of these contingent guarantees will expire without being funded.  We also were contingently liable for purchase obligations of $75 million and $72 million, at June 30, 2012 and December 31, 2011, respectively.

Product warranty liability accruals were $22 million at June 30, 2012 and $23 million at December 31, 2011.

Corning is a defendant in various lawsuits, including environmental litigation, product-related suits, the Dow Corning and PCC matters, and is subject to various claims which arise in the normal course of business.  In the opinion of management, the likelihood that the ultimate disposition of these matters will have a material adverse effect on Corning’s consolidated financial position, liquidity, or results of operations, is remote.

-8-

In March of 2012, Corning received a grand jury subpoena issued in the United States District Court for the Eastern District of Michigan from the U.S. Department of Justice in connection with an investigation into conduct relating to possible antitrust law violations involving certain automotive products, including catalytic converters, diesel particulate filters, substrates and monoliths. Antitrust investigations can result in significant penalties being imposed by the antitrust authorities. Currently Corning can not estimate the ultimate financial impact, if any, resulting from the investigation.  Such potential impact, if an antitrust violation by Corning is found, could however, be material to the results of operations of Corning in a particular period.

Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act, or by state governments under similar state laws, as a potentially responsible party for 18 hazardous waste sites.  Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise.  It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants.  At June 30, 2012, and December 31, 2011, Corning had accrued approximately $24 million (undiscounted) and $25 million (undiscounted), respectively, for the estimated liability for environmental cleanup and related litigation.  Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company’s liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

3.      Debt

Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $3.6 billion at June 30, 2012 and $2.6 billion at December 31, 2011.  The Company measures the fair value of its long-term debt using Level 2 inputs based primarily on current market yields for its existing debt traded in the secondary market.

2012

In the first quarter of 2012, we issued $250 million of 4.70% senior unsecured notes and $500 million of 4.75% senior unsecured notes for net proceeds of approximately $247 million and $495 million, respectively.  The 4.70% notes mature on March 15, 2037 and the 4.75% notes mature on March 15, 2042.

2011

In the second quarter of 2011, a wholly-owned subsidiary entered into a credit facility that allows Corning to borrow up to Chinese Renminbi (RMB) 4.0 billion, or approximately $633 million when translated to United States dollars.  Corning may request advances during the eighteen month period beginning on June 30, 2011 (the “Availability Period”).  Corning will repay the aggregate principal amount and accrued interest outstanding at the end of the Availability Period in six installments, with the final payment due in August, 2016, five years from the date of the first advance.

4.      Income Taxes

Our provision for income taxes and the related effective income tax rates were as follows (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Provision for income taxes	$	(93)	$	(123)	$	(204)	$	(237)
Effective tax rate		16.8%		14.0%		18.1%		13.6%

-9-

For the three and six months ended June 30, 2012, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of nonconsolidated affiliates reported in the financials net of tax;

·   The expiration of favorable U.S. tax provisions; and

·   The benefit of tax incentives in foreign jurisdictions, primarily Taiwan.

For the three and six months ended June 30, 2011, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of affiliated companies; and

·   The benefit of tax incentives in foreign jurisdictions, primarily Taiwan.

Certain foreign subsidiaries in China and Taiwan are operating under tax holiday arrangements.  The nature and extent of such arrangements vary, and the benefits of such arrangements phase out through 2015 according to the specific terms and schedules of the relevant taxing jurisdictions. The impact of the tax holiday on our effective tax rate is a reduction in the rate of 1.4 and 1.3 percentage points for the three months ended June 30, 2012 and 2011, respectively.  The impact of the tax holiday on our effective tax rate is a reduction in the rate of 1.4 percentage points for the six months ended June 30, 2012 and 2011.

While we expect the amount of unrecognized tax benefits to change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or our financial position.

5.      Earnings per Common Share

The reconciliation of the amounts used in the basic and diluted earnings per common share computations follows (in millions, except per share amounts):

	Three months ended June 30,
	2012			2011
	Net income attributable to Corning Incorporated	Weighted- average shares	Per share amount	Net income attributable to Corning Incorporated	Weighted- average shares	Per share amount
Basic earnings per common share	$462	1,506	$0.31	$755	1,568	$0.48
Effect of dilutive securities:
Stock options and other dilutive securities		12			23
Diluted earnings per common share	$462	1,518	$0.30	$755	1,591	$0.47

-10-

	Six months ended June 30,

	Net income attributable to Corning Incorporated	Weighted- average shares	Per share amount	Net income attributable to Corning Incorporated	Weighted- average shares	Per share amount
Basic earnings per common share	$924	1,511	$0.61	$1,503	1,566	$0.96
Effect of dilutive securities:
Stock options and other dilutive securities		13			24
Diluted earnings per common share	$924	1,524	$0.61	$1,503	1,590	$0.95

The following potential common shares were excluded from the calculation of diluted earnings per common share because their inclusion would have been anti-dilutive (in millions):

	Three months ended June 30,		Six months ended June 30,
	2012	2011	2012	2011
Stock options and other dilutive securities excluded from the calculation of diluted earnings per common share	42	26	42	48

6.      Available-for-Sale Investments

The following is a summary of the fair value of available-for-sale investments (in millions):

	Amortized cost				Fair value
	June 30, 2012		December 31, 2011		June 30, 2012		December 31, 2011
Bonds, notes and other securities:
U.S. government and agencies	$	1,333	$	1,150	$	1,337	$	1,155
Other debt securities				6				9
Total short-term investments	$	1,333	$	1,156	$	1,337	$	1,164
Asset-backed securities	$	54	$	57	$	35	$	35
Total long-term investments	$	54	$	57	$	35	$	35

We do not intend to sell, nor do we believe it is more likely than not that we would be required to sell, the long-term investment asset-backed securities (which are collateralized by mortgages) before recovery of their amortized cost basis.  It is possible that a significant degradation in the delinquency or foreclosure rates in the underlying assets could cause further temporary or other-than-temporary impairments in the future.

The following table summarizes the maturities at market value of available-for-sale securities at June 30, 2012 (in millions):

Less than one year	$1,031
Due in 1-5 years	306
Due in 5-10 years
Due after 10 years (1)	35
Total	$1,372

(1) Includes $35 million of asset-based securities that mature over time and are being reported at their final maturity dates.

Unrealized gains and losses, net of tax, are computed on a specific identification basis and are reported as a separate component of accumulated other comprehensive loss in shareholders’ equity until realized.

The following tables provide the fair value and gross unrealized losses of the Company’s investments aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2012 and December 31, 2011 (in millions):

		June 30, 2012
		12 months or greater				Total
	Number of securities in a loss position	Fair value		Unrealized losses (1)		Fair value		Unrealized losses
Asset-backed securities	22	$	35	$	(19)	$	35	$	(19)
Total long-term investments	22	$	35	$	(19)	$	35	$	(19)

(1) Unrealized losses in securities less than 12 months were not significant.

		December 31, 2011
		12 months or greater				Total
	Number of securities in a loss position	Fair value		Unrealized losses (1)		Fair value		Unrealized losses

Total long-term investments	22	$	35	$	(23)	$	35	$	(23)

(1) Unrealized losses in securities less than 12 months were not significant.

As of June 30, 2012 and December 31, 2011, for securities that have credit losses, an other than temporary impairment loss of $15 and $18 million, respectively, is recognized in accumulated other comprehensive loss.

Proceeds from sales and maturities of short-term investments totaled $1.0 billion and $1.9 billion for the six months ended June 30, 2012 and 2011, respectively.

Corning owns 50% of Samsung Corning Precision.  Samsung Display Co., Ltd. owns 43% and other shareholders own the remaining 7%.

In June 2011, the Korean tax authorities completed an audit of Samsung Corning Precision.  As a result, Samsung Corning Precision was issued a pre-assessment of approximately $46 million for an asserted underpayment of withholding tax on dividends paid from September 2006 through March 2009.  In April 2011, we appealed for a reversal of the assessment. In October 2011, that appeal was denied and a formal assessment was issued.  Corning paid the assessment in the fourth quarter of 2011, allowing us to appeal to the Korean Tax Tribunal.  Once a ruling from the Korean Tax Tribunal is received, Corning may continue the Korean appeals process and/or access the Competent Authority under the U.S./Korea tax treaty, which allows the U.S. tax authorities’ involvement in resolving the matter.  Samsung Corning Precision and Corning believe it is more likely than not we will receive a favorable ruling when all of the available appeals have been exhausted.

Dow Corning Corporation (Dow Corning)

Dow Corning is a U.S.-based manufacturer of silicone products.  Dow Corning’s results of operations follow (in millions):

	Three months ended June 30,				Six months ended June 30
	2012		2011		2012		2011
Statement of Operations:
Net sales	$	1,571	$	1,668	$	3,093	$	3,247
Gross profit	$	395	$	533	$	732	$	1,072

Related Party Transactions:

Dividends received from Dow Corning			$	65			$	180

Amounts owed to Dow Corning totaled $1 million as of June 30, 2012.  At December 31, 2011, amounts owed to Dow Corning were not significant.

At June 30, 2012, Dow Corning’s marketable securities included approximately $138 million of auction rate securities, net of a temporary impairment of $6 million.

Corning and The Dow Chemical Company (Dow Chemical) each own 50% of the common stock of Dow Corning.  In May 1995, Dow Corning filed for bankruptcy protection to address pending and claimed liabilities arising from many thousands of breast implant product lawsuits.  On June 1, 2004, Dow Corning emerged from Chapter 11 with a Plan of Reorganization (the Plan) which provided for the settlement or other resolution of implant claims.  Under the terms of the Plan, Dow Corning has established and is funding a Settlement Trust and a Litigation Facility to provide a means for tort claimants to settle or litigate their claims.  Inclusive of insurance, Dow Corning has paid approximately $1.7 billion to the Settlement Trust.

As of June 30, 2012, Dow Corning had recorded a reserve for breast implant litigation of $1.6 billion.  As a separate matter arising from the bankruptcy proceedings, Dow Corning is defending claims asserted by a number of commercial creditors who claim additional interest at default rates and enforcement costs, during the period from May 1995 through June 2004.  As of June 30, 2012, Dow Corning has estimated the liability to commercial creditors to be within the range of $88 million to $287 million.  As Dow Corning management believes no single amount within the range appears to be a better estimate than any other amount within the range, Dow Corning has recorded the minimum liability within the range.  Should Dow Corning not prevail in this matter, Corning’s equity earnings would be reduced by its 50% share of the amount in excess of $88 million, net of applicable tax benefits.

Variable Interest Entities

For variable interest entities, we routinely assess the terms of our interest in each entity to determine if we are the primary beneficiary as prescribed by U.S. GAAP.  We currently have three variable interest entities that are not considered significant to Corning’s consolidated financial statements.  Corning does not have retained interests in assets transferred to any unconsolidated entity that serves as credit, liquidity or market risk support to such entity.

Corning and certain of its domestic subsidiaries offer postretirement plans that provide health care and life insurance benefits for retirees and eligible dependents.  Certain employees may become eligible for such postretirement benefits upon reaching retirement age and service requirements.  For current retirees (including surviving spouses) and active employees eligible for the salaried retiree medical program, we placed a “cap” on the amount we will contribute toward retiree medical coverage in the future.  The cap equals 120% of our 2005 contributions toward retiree medical benefits.  Once our contributions toward salaried retiree medical costs reach this cap, impacted retirees will have to pay the excess amount in addition to their regular contributions for coverage.  This cap was attained for post-65 retirees in 2008 and has impacted their contribution rate in 2009 and going forward.  The pre-65 retirees triggered the cap in 2010, which has impacted their contribution rate in 2011 and going forward.  Furthermore, employees hired or rehired on or after January 1, 2007 will be eligible for Corning retiree medical upon retirement; however, these employees will pay 100% of the cost.

12.      Hedging Activities

Corning operates in many foreign countries and as a result is exposed to movements in foreign currency exchange rates.  The areas in which exchange rate fluctuations affect us include:

·   Financial instruments and transactions denominated in foreign currencies, which impact earnings; and

·   The translation of net assets in foreign subsidiaries for which the functional currency is not the U.S. dollar, which impacts our net equity.

Our most significant foreign currency exposures relate to the Japanese yen, Korean won, New Taiwan dollar and the Euro.  We manage our foreign currency exposures, which include forecasted transactions, primarily by entering into foreign exchange forward contracts with durations of generally 18 months or less to hedge foreign currency risk.  The hedges are scheduled to mature coincident with the timing of the underlying foreign currency commitments and transactions.  The objective of these contracts is to neutralize the impact of exchange rate movements on our operating results.

-17-

The forward and option contracts we use in managing our foreign currency exposures contain an element of risk in that the counterparties may be unable to meet the terms of the agreements.  However, we minimize this risk by limiting the counterparties to a diverse group of highly-rated major domestic and international financial institutions with which we have other financial relationships.  We are exposed to potential losses in the event of non-performance by these counterparties.  However, we do not expect to record any losses as a result of such counterparty default.  Neither we nor our counterparties are required to post collateral for these financial instruments.

Cash Flow Hedges

Our cash flow hedging activities utilize foreign exchange forward contracts to reduce the risk that movements in exchange rates will adversely affect the eventual net cash flows resulting from the sale of products to foreign customers and purchases from foreign suppliers.  Our cash flow hedging activity also utilizes interest rate forwards to reduce the risk of changes in benchmark interest rate from the probable forecasted issuance of debt.  Corning uses a regression analysis to monitor the effectiveness of its cash flow hedges both prospectively and retrospectively.  Corning defers net gains and losses from cash flow hedges into accumulated other comprehensive income on the consolidated balance sheet until such time as the hedged item impacts earnings.  At June 30, 2012, the amount of net gain expected to be reclassified into earnings within the next 12 months is $15 million.

Undesignated Hedges

Corning uses other foreign exchange forward contracts that are not designated as hedging instruments for accounting purposes.  The undesignated hedges limit exposures to foreign currency fluctuations related to certain monetary assets, monetary liabilities and net earnings in foreign currencies.

13.      Fair Value Measurements

Fair value standards under U.S. GAAP define fair value, establish a framework for measuring fair value in applying generally accepted accounting principles, and require disclosures about fair value measurements.  The standards also identify two kinds of inputs that are used to determine the fair value of assets and liabilities: observable and unobservable.  Observable inputs are based on market data or independent sources while unobservable inputs are based on the Company’s own market assumptions.  Once inputs have been characterized, the inputs are prioritized into one of three broad levels (provided in the table below) used to measure fair value.

Fair value standards apply whenever an entity is measuring fair value under other accounting pronouncements that require or permit fair value measurement and require the use of observable market data when available.  As of June 30, 2012 and December 31, 2011, the Company did not have any financial assets or liabilities that were measured using unobservable (or Level 3) inputs.

The following tables provide fair value measurement information for the Company’s major categories of financial assets and liabilities measured on a recurring basis (in millions):

		Fair value measurements at reporting date using
	June 30,  2012	Quoted prices in active markets for identical assets (Level 1)	Significant other observable inputs (Level 2)	Significant unobservable inputs (Level 3)
Current assets:

Current liabilities:
Other accrued liabilities (1)	$     34		$34
Non-current liabilities:
Other liabilities (1)	$       4		$  4

(1) Derivative assets and liabilities include foreign exchange contracts which are measured using observable quoted prices for similar assets and liabilities.

(2) Other assets include $35 million of asset-backed securities which are measured using observable quoted prices for similar assets.

14.      Share-based Compensation

Stock Compensation Plans

The Company measures and recognizes compensation cost for all share-based payment awards made to employees and directors based on estimated fair values.  Fair values for stock options were estimated using a multiple-point Black-Scholes valuation model.  Share-based compensation cost was approximately $16 million and $22 million for the three months ended June 30, 2012 and 2011, respectively, and approximately $40 million and $45 million for the six months ended June 30, 2012 and 2011, respectively.  Amounts for all periods presented included (1) employee stock options, (2) time-based restricted stock and restricted stock units, and (3) performance-based restricted stock and restricted stock units.

Stock Options

Our Stock Option Plans provide non-qualified and incentive stock options to purchase authorized but unissued shares or treasury shares at the market price on the grant date and generally become exercisable in installments from one to five years from the grant date.  The maximum term of non-qualified and incentive stock options is 10 years from the grant date.

-21-

The following table summarizes information concerning stock options outstanding including the related transactions under the Stock Option Plans for the six months ended June 30, 2012:

	Number of Shares (in thousands)	Weighted- Average Exercise Price	Weighted- Average Remaining Contractual Term in Years	Aggregate Intrinsic Value (in thousands)
Options Outstanding as of December 31, 2011	65,027	$15.91
Granted	7,623	12.99
Exercised	(2,839)	6.76
Forfeited and Expired	(1,162)	18.07
Options Outstanding as of June 30, 2012	68,649	15.93	5.05	94,692
Options Exercisable as of June 30, 2012	55,406	15.89	4.12	94,459

The aggregate intrinsic value (market value of stock less option exercise price) in the preceding table represents the total pretax intrinsic value, based on the Company’s closing stock price on June 30, 2012, which would have been received by the option holders had all option holders exercised their options as of that date.

As of June 30, 2012, there was approximately $41 million of unrecognized compensation cost related to stock options granted under the Plans.  The cost is expected to be recognized over a weighted-average period of two years.  Compensation cost related to stock options was approximately $21 million and $25 million for the six months ended June 30, 2012 and 2011, respectively, and approximately $9 million and $13 million for the three months ended June 30, 2012 and 2011 respectively.

Proceeds received from the exercise of stock options were $19 million and $73 million for the six months ended June 30, 2012 and 2011, respectively and $3 million and $9 million for the three months ended June 30, 2012 and 2011, respectively.  Proceeds received from the exercise of stock options were included in financing activities on the Company’s Consolidated Statements of Cash Flows.  The total intrinsic value of options exercised for the six months ended June 30, 2012 and 2011 was approximately $20 million and $68 million, and $5 million and $6 million for the three months ended June 30, 2012 and 2011, respectively, which is currently deductible for tax purposes. However, these tax benefits were not recognized due to net operating loss carryforwards available to the Company.  Refer to Note 4 (Income Taxes) to the consolidated financial statements.

The following inputs were used for the valuation of option grants under our Stock Option Plans:

	Three months ended June 30,		Six months ended June 30,
	2012	2011	2012	2011
Expected volatility	48%	47-48%	48-49%	47-48%
Weighted-average volatility	48%	47%	48-49%	47-48%
Expected dividends	2.28%	1.06%	2.28-2.33%	1.1%
Risk-free rate	0.9-1.2%	1.9-2.4%	0.9-1.3%	1.9-2.7%
Average risk-free rate	1.2%	2.4%	1.2-1.3%	2.4-2.6%
Expected term (in years)	5.7-7.1	5.1-6.7	5.7-7.1	5.1-6.7
Pre-vesting departure rate	0.4-4.2%	0.4-3.9%	0.4-4.2%	0.4-3.9%

-22-

Expected volatility is based on a blended approach defined as the weighted average of the short-term implied volatility, the most recent volatility for the period equal to the expected term and the most recent 15-year historical volatility.  The expected term assumption is the period of time the options are expected to be outstanding, and is calculated using a combination of historical exercise experience adjusted to reflect the current vesting period of options being valued, and partial life cycles of outstanding options.  The risk-free rate assumption is the implied rate for a zero-coupon U.S. Treasury bond with a term equal to the option’s expected term.  The ranges given above result from different groups of employees exhibiting different exercise behavior.

Incentive Stock Plans

The Corning Incentive Stock Plan permits stock grants, either determined by specific performance goals or issued directly, in most instances, subject to the possibility of forfeiture and without cash consideration.  Shares under the Incentive Stock Plan are granted at the market price on the grant date, contingently vest over a period of 1 to 10 years, and have contractual lives of 1 to 10 years.

The fair value of each restricted stock grant under the Incentive Stock Plans was estimated on the date of grant for performance-based grants assuming that performance goals will be achieved.  The expected term for grants under the Incentive Stock Plans is 1 to 10 years.

Time-Based Restricted Stock and Restricted Stock Units:

Time-based restricted stock and restricted stock units are issued by the Company on a discretionary basis, and are payable in shares of the Company’s common stock upon vesting.  The fair value is based on the market price of the Company’s stock on the grant date.  Compensation cost is recognized over the requisite vesting period and adjusted for actual forfeitures before vesting.

The following table represents a summary of the status of the Company’s non-vested time-based restricted stock and restricted stock units as of December 31, 2011, and changes which occurred during the six months ended June 30, 2012:

	Shares (000’s)	Weighted Average Grant-Date Fair Value
Non-vested shares at December 31, 2011	4,104	$	18.16
Granted	1,953		13.09
Vested	(411)		21.08
Forfeited	(65)		15.16
Non-vested shares at June 30, 2012	5,581	$	16.20

As of June 30, 2012, there was approximately $32 million of unrecognized compensation cost related to non-vested time-based restricted stock compensation arrangements granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 1.8 years.  Compensation cost related to time-based restricted stock and restricted stock units was approximately $17 million and $16 million for the six months ended June 30, 2012 and 2011, respectively, and $7 million for the three months ended June 30, 2012 and 2011.

Performance-Based Restricted Stock and Restricted Stock Units:

Performance-based restricted stock and restricted stock units are earned upon the achievement of certain targets, and are payable in shares of the Company’s common stock upon vesting, typically over a three-year period.  The fair value is based on the market price of the Company’s stock on the grant date and assumes that the target payout level will be achieved.  Compensation cost is recognized over the requisite vesting period and adjusted for actual forfeitures before vesting.  During the performance period, compensation cost may be adjusted based on changes in the expected outcome of the performance-related target.

-23-

The following table represents a summary of the status of the Company’s non-vested performance-based restricted stock and restricted stock units as of December 31, 2011, and changes which occurred during the six months ended June 30, 2012:

	Shares (000’s)	Weighted- Average Grant-Date Fair Value
Non-vested restricted stock and restricted stock units at December 31, 2011	5,134	$	8.67
Vested	(5134)		8.67
Non-vested restricted stock and restricted stock units at June 30, 2012	0	$	0

The performance-based restricted stock and restricted stock unit compensation program was terminated in 2010.  All performance-based restricted stock and stock units are vested as of June 30, 2012.

As of June 30, 2012, there is no unrecognized compensation cost related to non-vested performance-based restricted stock and restricted stock units compensation arrangements granted under the Plan.  Compensation cost related to performance-based restricted stock and restricted stock units was approximately $2 million and $4 million for the six months ended June 30, 2012 and 2011, respectively, and $2 million for the three months ended June 30, 2011.

15.      Significant Customers

For the three and six months ended June 30, 2012 and 2011, Corning did not have a customer that individually accounted for more than 10% of the Company’s consolidated net sales, respectively.

16.      Reportable Segments

Our reportable segments are as follows:

·   Display Technologies – manufactures liquid crystal display (LCD) glass for flat panel displays.

·   Telecommunications – manufactures optical fiber and cable, and hardware and equipment components for the telecommunications industry.

·   Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.  This reportable segment is an aggregation of our Automotive and Diesel operating segments as these two segments share similar economic characteristics, products, customer types, production processes and distribution methods.

·   Specialty Materials – manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for unique customer needs.

·   Life Sciences – manufactures glass and plastic consumables for scientific applications.

All other segments that do not meet the quantitative threshold for separate reporting are grouped as “All Other.”  This group is primarily comprised of development projects and results for new product lines.

We prepared the financial results for our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions.  We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income.  We have allocated certain common expenses among segments differently than we would for stand-alone financial information prepared in accordance with U.S. GAAP.  Segment net income may not be consistent with measures used by other companies.  The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements.

In the Telecommunications operating segment, assets increased from $1.2 billion at December 31, 2011 to $1.4 billion at June 30, 2012.  The increase is due primarily to increase of capital expenditures of approximately $170 million.

The sales of each of our reportable segments are concentrated across a relatively small number of customers.  In the second quarter of 2012, the following number of customers, which individually accounted for 10% or more of each segment’s sales, represented the following concentration of segment sales:

·   In the Display Technologies segment, 4 customers accounted for 78% of total segment sales.

·   In the Telecommunications segment, 1 customer accounted for 12% of total segment sales.

·   In the Environmental Technologies segment, 3 customers accounted for 87% of total segment sales.

·   In the Specialty Materials segment, 2 customers accounted for 48% of total segment sales.

·   In the Life Sciences segment, 2 customers accounted for 45% of total segment sales.

In the first half of 2012, the following number of customers, which individually accounted for 10% or more of each segment’s sales, represented the following concentration of segment sales:

·   In the Display Technologies segment, 4 customers accounted for 79% of total segment sales.

·   In the Telecommunications segment, 1 customer accounted for 12% of total segment sales.

·   In the Environmental Technologies segment, 3 customers accounted for 87% of total segment sales.

·   In the Specialty Materials segment, 2 customers accounted for 49% of total segment sales.

·   In the Life Sciences segment, 2 customers accounted for 42% of total segment sales.

A significant amount of specialized manufacturing capacity for our Display Technologies segment is concentrated in Asia.  It is at least reasonably possible that the operation of a facility could be disrupted.  Due to the specialized nature of the assets, it would not be possible to find replacement capacity quickly.  Accordingly, loss of these facilities could produce a near-term severe impact on our display business and the Company as a whole.

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

ORGANIZATION OF INFORMATION

Management’s Discussion and Analysis provides a historical and prospective narrative on the Company’s financial condition and results of operations.  The discussion includes the following sections:

·   Overview

·   Results of Operations

·   Reportable Segments

·   Liquidity and Capital Resources

·   Critical Accounting Estimates

·   New Accounting Standards

·   Environment

·   Forward-Looking Statements

OVERVIEW

The decrease in Corning’s results in the three and six months ended June 30, 2012, when compared to the same periods in 2011, is largely the result of significant price declines in our Display Technologies segment.  Although sequential price declines were much more moderate in the second quarter of 2012, year-over-year prices declined in the double digits in the Display Technologies segment, due to customer and competitive pressures in a period of excess capacity, which was driven by a smaller glass market and a reduction in the amount of inventory in the supply chain beginning in the latter half of 2011 and continuing into 2012.  In addition to price declines in the Display Technologies segment, Corning’s results were also negatively impacted by sharply lower equity earnings from our equity affiliates, lower royalty income and higher taxes.

Results in our remaining reportable segments in the three and six months ended June 30, 2012 were mixed when compared to the same periods in 2011.  Operating results increased in our Specialty Materials segment, driven by double digit sales growth of our Corning® Gorilla® Glass used in portable display devices.  Results also increased in the Environmental Technologies segment in these periods, driven by improved manufacturing performance and lower air freight expenses.  Although sales increased in the Telecommunications segment in the second quarter and first half of 2012 driven by strong sales of optical fiber and cable products, results declined when compared to the prior year due to an increase in manufacturing and operating expenses and higher project spending.  Sales in the Life Sciences segment increased slightly, largely as a result of a small acquisition completed in the fourth quarter of 2011, but results declined due to an increase in operating expenses related to a pending acquisition announced in April, 2012.

In the second quarter of 2012, we generated net income of $462 million or $0.30 per share, compared to net income of $755 million or $0.47 per share for the same period in 2011.  In the six months ended June 30, 2012, we reported net income of $924 million or $0.61 per share compared to net income of $1,503 million or $0.95 per share for the first half of 2011. When compared to the same periods last year, the decrease in net income was due largely to the following items:

-27-

·   Lower net income in the Display Technologies segment driven by the price declines described above, and a decrease in equity earnings from Samsung Corning Precision, our equity affiliate located in Korea;

·   A decline in equity earnings from Dow Corning due to a decrease in prices for silicone products and a significant decrease in earnings at Hemlock Semiconductor Group (Hemlock), Dow Corning’s consolidated subsidiary that manufactures high purity polycrystalline silicon for the semiconductor and solar industries, driven by price declines and lower volume;

·   Lower royalty income from our equity affiliate Samsung Corning Precision due to the combination of lower sales at Samsung Corning Precision and the reduction of the applicable royalty rate which took effect in December, 2011;

·   An increase in our effective tax rate due to the following:

o   Expiration of favorable U.S. tax provisions;

o   The partial expiration of tax holidays in Taiwan; and

o   Change in our mix of earnings.

The decrease in net income for the three and six months ended June 30, 2012 was offset somewhat by the positive impact of movements in foreign exchange rates and improvements in net income in the Specialty Materials and Environmental Technologies segments.

Our key priorities for 2012 remain similar to those from previous years:  protect our financial health and invest in the future.  During the second quarter of 2012, we made the following progress toward these priorities:

Protecting Financial Health

Our balance sheet remains strong, and we generated positive cash flow from operating activities:

·   We ended the second quarter of 2012 with $6.3 billion of cash, cash equivalents and short-term investments, up from the balance at December 31, 2011 of $5.8 billion, and well above our debt balance at June 30, 2012 of $3.3 billion.

·   Although our debt to capital ratio increased from 10% reported at December 31, 2011 to 13% at June 30, 2012 due to the issuance of unsecured notes in the first quarter of 2012, our debt to capital ratio remains at a low level.

·   We repurchased 25.7 million shares of common stock in the second quarter of 2012 as part of a $1.5 billion repurchase program announced in the fourth quarter of 2011.  This action reflects our significant cash balance, our expectation that we will continue to achieve strong cash flows in the future, and our belief that Corning’s stock is a good value.

·   Operating cash flow in the six months ended June 30, 2012 was $1,332 million, an increase of $213 million when compared to the same period in 2011.

Investing In Our Future

We continue to focus on the future and on what we do best – creating and making keystone components that enable high-technology systems.  Our spending levels for research, development, and engineering increased slightly in the second quarter of 2012 when compared to the same period last year, as we remain committed to investing in research, development, and engineering to drive innovation.

In 2012, we are maintaining a balanced innovation strategy that is focused on: growing our existing businesses; developing opportunities adjacent or closely related to our existing technical and manufacturing capabilities; and investing in long range opportunities in each of our market segments.

-28-

We continue to work on new products, including glass substrates for high performance displays, LCD applications, diesel filters and substrates, and the optical fiber, cable, hardware and equipment that enable fiber-to-the-premises and next generation data centers.  In addition, we are focusing on wireless solutions for diverse venue applications, such as distributed antenna systems, fiber to the cell site and fiber to the antenna.  We have increased our research, development and engineering spending to support the advancement of new product attributes for our Corning Gorilla Glass suite of products.  We will continue to focus on adjacent glass opportunities which leverage existing materials or manufacturing processes, including products such as glass substrates for thin-film photovoltaics in solar applications and Corning® Willow™ Glass, our ultra-slim flexible glass for use in next-generation consumer electronic technologies.

Capital spending totaled $853 million and $1.0 billion for the six months ended June 30, 2012 and 2011, respectively.  Spending in the first half of 2012 was driven primarily by capacity expansion projects in several of our reportable segments that were started in 2011.  We expect our 2012 capital spending to be $1.8 to $1.9 billion.  Approximately $900 million will be directed toward our Display Technologies segment, of which approximately $300 million is related to 2011 capital projects.

Corporate Outlook

Corning expects sales in 2012 to remain relatively consistent with 2011, with higher sales in our Telecommunications, Specialty Materials, Life Sciences and Environmental Technologies segments offset by lower sales in the Display Technologies segment.  We expect the overall LCD glass retail market to increase from 3.3 billion square feet in 2011 to approximately 3.6 billion square feet in 2012, driven by the combination of an increase in retail sales of LCD televisions, the demand for larger television screen sizes and growth in the personal computer market.  We expect that sequential quarterly price declines during the remainder of 2012 will be moderate.  Net income will be negatively impacted by lower equity earnings from our equity affiliates Samsung Corning Precision, driven by lower prices, and Dow Corning, driven by lower demand and price declines at Hemlock Semiconductor Group, Dow Corning’s consolidated subsidiary that makes high purity polycrystalline silicon for the semiconductor and solar industries.  We may take advantage of acquisition opportunities that support the long-term strategies of our businesses.  We remain confident that our strategy to grow through global innovation, while preserving our financial stability, will enable our continued long-term success.

Net Sales

For the three and six months ended June 30, 2012, net sales declined when compared to the same periods in 2011, driven by the impact of lower prices in our Display Technologies segment, offset somewhat by higher sales in the Specialty Materials, Telecommunications and Life Sciences segments.  For the three and six months ended June 30, 2012, net sales were not significantly impacted by movements in foreign exchange rates.

Cost of Sales

The types of expenses included in the cost of sales line item are: raw materials consumption, including direct and indirect materials; salaries, wages, and benefits; depreciation and amortization; production utilities; production-related purchasing; warehousing (including receiving and inspection); repairs and maintenance; inter-location inventory transfer costs; production and warehousing facility property insurance; rent for production facilities; and other production overhead.

-30-

Gross Margin

As a percentage of net sales, gross margin for the three and six months ended June 30, 2012 decreased when compared to the same periods last year, due primarily to lower prices in our Display Technologies segment, offset somewhat by improvements in manufacturing performance in the Specialty Materials and Environmental Technologies segments, and the absence of costs related to large cover glass start-up and tank conversions incurred in the first half of 2011.

Selling, General, and Administrative Expenses

For the three and six months ended June 30, 2012, selling, general, and administrative expenses increased by $7 million and $36 million, respectively, driven by the integration impact of two small acquisitions completed in 2011 and acquisition-related operating expenses.  As a percentage of net sales, these expenses also increased when compared to the same period last year.

The types of expenses included in the selling, general, and administrative expenses line item are: salaries, wages, and benefits; stock-based compensation expense; travel; sales commissions; professional fees; depreciation and amortization, utilities, and rent for administrative facilities.

Research, Development, and Engineering Expenses

For the three and six months ended June 30, 2012, research, development, and engineering expenses increased by $16 million and $47 million, respectively, when compared to the same periods last year, driven by an increase in spending in our Telecommunications, Environmental Technologies and Specialty Materials segments, and by our continuing focus on baseline research for new product development.  As a percentage of net sales, research, development, and engineering expenses for the three and six months ended June 30, 2012, also increased when compared to the same periods in 2011.

Equity in Earnings of Affiliated Companies

The following provides a summary of equity in earnings of associated companies (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Samsung Corning Precision	$	193	$	325	$	376	$	624
Dow Corning Corporation		61		95		96		186
All other		5		8		5		16
Total equity earnings	$	259	$	428	$	477	$	826

Equity earnings of affiliated companies decreased significantly for the three and six months ended June 30, 2012, when compared to the same periods last year, reflecting lower earnings performance at both Samsung Corning Precision and Dow Corning.  The decrease was offset somewhat by the favorable impact of movements in foreign exchange rates in the three and six months ended June 30, 2012.

The change in equity earnings from Samsung Corning Precision is explained more fully in the discussion of the performance of the Display Technologies segment and in All Other.

The decrease in equity earnings from Dow Corning in the three and six months ended June 30, 2012 was largely due to the following items:

·   Declines in governmental subsidies in the solar panel industry and over-capacity at all levels of the solar supply chain, which led to significant declines in polycrystalline silicon prices at Hemlock;

·   Price declines and higher raw materials costs for silicone products;

·   Higher operating expenses due to an increase in pension expense and severance accruals;

·   The unfavorable impact from movements in foreign exchange rates.

-31-

The decrease in equity earnings from Dow Corning was offset somewhat by a slight increase in volume for silicone products, lower interest expense and two small non-recurring gains of approximately $11 million recorded in the second quarter of 2012.

On July 20, 2012, the Chinese Ministry of Commerce (“MOFCOM”) initiated antidumping and countervailing duty investigations of imports of solar-grade polycrystalline silicon products from the U.S. and Korea, based on a petition filed by Chinese solar-grade polycrystalline silicon producers.  The petition alleges that producers within these countries exported solar-grade polycrystalline silicon to China at less than fair value, and that production of solar-grade polycrystalline silicon in the U.S. has been subsidized by the U.S. government.  If the Chinese authorities find evidence of dumping or subsidization, they may impose additional duties on future imports of solar-grade polycrystalline silicon to China from the U.S.  Dow Corning expects to fully cooperate with MOFCOM in the investigations and to vigorously contest the allegations.  As the outcome of such actions is uncertain, Dow Corning cannot predict the ultimate impact of these matters.

Outlook:

In the third quarter of 2012, we expect sequential equity earnings from Dow Corning to decline approximately 30%, driven primarily by the absence of the non-recurring gains recorded in the second quarter of 2012.

Other Income, Net

“Other income, net” in Corning’s consolidated statements of income includes the following (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Royalty income from Samsung Corning Precision	$	21	$	64	$	43	$	125

Total	$	8	$	43	$	37	$	70

Income Before Income Taxes

Income before income taxes for the three and six months ended June 30, 2012, was slightly impacted by favorable movements in foreign exchange rates when compared to the same periods last year.

Provision for Income Taxes

Our provision for income taxes and the related effective income tax rates were as follows (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Provision for income taxes	$	(93)	$	(123)	$	(204)	$	(237)
Effective tax rate		16.8%		14.0%		18.1%		13.6%

For the three and six months ended June 30, 2012, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of nonconsolidated affiliates reported in the financials net of tax;

·   The expiration of favorable U.S. tax provisions; and

·   The benefit of tax incentives in foreign jurisdictions, primarily Taiwan.

-32-

For the three and six months ended June 30, 2011, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of nonconsolidated affiliates reported in the financials net of tax; and

·   The benefit of tax holiday incentives in foreign jurisdictions, primarily Taiwan.

Refer to Note 4 (Income Taxes) to the consolidated financial statements for additional information.

Net Income Attributable to Corning Incorporated

REPORTABLE SEGMENTS

Our reportable segments are as follows:

·   Display Technologies – manufactures liquid crystal display glass for flat panel displays.

·   Telecommunications – manufactures optical fiber and cable, and hardware and equipment components for the telecommunications industry.

·   Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.  This reportable segment is an aggregation of our Automotive and Diesel operating segments, as these two segments share similar economic characteristics, products, customer types, production processes and distribution methods.

·   Specialty Materials – manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for unique customer needs.

·   Life Sciences – manufactures glass and plastic consumables for scientific applications.

All other reportable segments that do not meet the quantitative threshold for separate reporting are grouped as “All Other.”  This group is primarily comprised of development projects and results for new product lines.

We prepared the financial results for our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions.  We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income.  We have allocated certain common expenses among segments differently than we would for stand-alone financial information prepared in accordance with U.S. GAAP.  Segment net income may not be consistent with measures used by other companies.  The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements.

The following table provides net sales and other data for the Display Technologies segment (in millions):

	Three months ended June 30,				% change	Six months ended June 30,				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales	$	641	$	760	(16)%	$	1,346	$	1,550	(13)%
Equity earnings of affiliated companies	$	184	$	319	(42)%	$	366	$	613	(40)%
Net income	$	371	$	626	(41)%	$	792	$	1,264	(37)%

The decrease in net sales for the three months ended June 30, 2012, when compared to the same period last year, reflected the significant price declines we experienced beginning in the fourth quarter of 2011, and continuing into the first quarter of 2012, driven by customer and competitive pressures in a period of excess capacity.  The segment benefited from a modest increase in volume and the impact of favorable movements in foreign exchange rates, somewhat offsetting the steep price declines.  In the second quarter of 2012, the display industry began to see a slight improvement in its business environment, as panel makers experienced improving conditions and the rate of price declines slowed due to the tightening of supply and demand levels, resulting in much more moderate sequential price declines.

Net sales also declined in the six months ended June 30, 2012, when compared to the first half of 2011, reflecting the price declines described above, marginally offset by the positive impact of movements in foreign exchange rates and volume growth driven by the continuing demand for LCD glass utilized in computer notebooks, desktop monitors and LCD televisions.

The decrease in equity earnings from Samsung Corning Precision in the three and six months ended June 30, 2012 reflected substantial price declines driven by the circumstances described above, as well as a decrease in volume due to lower market share at one of its customers, when compared to the same periods last year.  The decrease was offset somewhat by the favorable impact of movements in foreign exchange rates.

When compared to the same periods last year, the decrease in net income in the Display Technologies segment in the three and six months ended June 30, 2012 primarily reflects the impact of price declines, lower equity earnings and a decrease in royalty income, partially offset by the favorable impact of foreign exchange rate movements.

A number of Corning's patents and know-how are licensed to Samsung Corning Precision, as well as to third parties, which generate royalty income.  Royalty income from Samsung Corning Precision decreased substantially in the three and six months ended June 30, 2012, when compared to the same periods last year, reflecting the decline in sales at Samsung Corning Precision and the reduction of the applicable royalty rate by approximately 50% which took effect on December 1, 2011.

Refer to Note 8 (Investments) to the consolidated financial statements for more information about related party transactions.

The Display Technologies segment has a concentrated customer base comprised of LCD panel and color filter makers primarily located in China, Japan and Taiwan.  For the three months ended June 30, 2012, four customers of the Display Technologies segment that individually accounted for more than 10% of segment net sales, accounted for approximately 78% of total segment sales when combined.  For the six months ended June 30, 2012, four customers of the Display Technologies segment that individually accounted for more than 10% of segment net sales, accounted for approximately 79% of total segment sales when combined. Our customers face the same global economic dynamics as we do in this market.  Our near-term sales and profitability would be impacted if any individual customers were unable to continue to purchase our products.

-34-

Samsung Corning Precision’s sales are also concentrated across a small number of its customers.  For the three and six months ended June 30, 2012, sales to two LCD panel makers located in Korea accounted for 94% of Samsung Corning Precision sales.

Outlook:

We expect the overall LCD glass retail market to increase from 3.3 billion square feet in 2011 to approximately 3.6 billion square feet in 2012.  We believe that the long-term market drivers will be LCD television growth, driven by growth of larger-sized LCD televisions and increased demand in emerging regions, as well as continued growth in the personal computer market.

In the third quarter of 2012, we expect LCD glass volume for the company’s wholly owned business and Samsung Corning Precision to grow in the low double digits sequentially and for price declines to remain moderate.

The end market demand for LCD televisions, monitors and notebooks is dependent on consumer retail spending, among other things.  We are cautious about the potential negative impacts that economic conditions, particularly a global economic recession, excess market capacity and world political tensions could have on consumer demand.  While the industry has grown rapidly in recent years, economic volatility along with consumer preferences for panels of differing sizes, prices, or other factors may lead to pauses in market growth.  Therefore, it is possible that glass manufacturing capacity may exceed demand from time to time.  We may incur further charges in this segment to reduce our workforce and consolidate capacity.  In addition, changes in foreign exchange rates, principally the Japanese yen, will continue to impact the sales and profitability of this segment.

Telecommunications

The following table provides net sales and other data for the Telecommunications segment (in millions):

	Three months ended June 30,				% change	Six months ended June 30,				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales:
Optical fiber and cable	$	302	$	265	14%	$	556	$	513	8%
Hardware and equipment		257		283	(9)%		511		509	0%
Total net sales	$	559	$	548	2%	$	1,067	$	1,022	4%
Net income	$	36	$	46	(22)%	$	57	$	87	(34)%

In the three and six months ended June 30, 2012, net sales of the Telecommunications segment increased when compared to the same periods last year, primarily due to strong sales of fiber and cable products in North America and China, coupled with a modest increase in sales of fiber-to-the-premises products, driven by the initiative in Australia to bring high-speed broadband services to residential single-family homes.  Offsetting these gains were lower hardware and equipment sales, largely due to the non-repeat of an enterprise network project which occurred in 2011, lower sales of legacy copper products and the unfavorable impact of movements in foreign exchange rates.

When compared to the same periods in 2011, the decrease in net income in the second quarter and first half of 2012 largely reflects higher operating and manufacturing expenses, driven by higher research and development expenses and an increase in project spending mainly to support fiber-to-the-premises initiatives and anticipated 2012 growth.  Additionally, net income in the first half of 2012 was impacted by the write off of a small equity affiliate in the first quarter of 2012.  Movements in foreign exchange rates did not significantly impact net income of this segment.

-35-

The Telecommunications segment has a concentrated customer base.  For the three and six months ended June 30, 2012, one customer of the Telecommunications segment represented approximately 12% of total segment sales in both periods.

Outlook:

In the third quarter of 2012, we expect sales to be consistent with the second quarter of 2012 and consistent with normal seasonal trends.

Environmental Technologies

The following table provides net sales and other data for the Environmental Technologies segment (in millions):

	Three months ended June 30,				% change	Six months ended June 30,				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales:
Automotive	$	120	$	121	(1)%	$	249	$	244	2%
Diesel		129		137	(6)%		263		273	(4)%
Total net sales	$	249	$	258	(3)%	$	512	$	517	(1)%
Net income	$	34	$	32	6%	$	74	$	61	21%

In the second quarter of 2012, sales of this segment decreased slightly when compared to the same period in 2011, mainly due to a decline in net sales of our diesel products.  Higher sales of our heavy duty diesel products were more than offset by a decline in sales of light duty diesel products, driven by a decline in demand for vehicles in Europe requiring light duty diesel filters.  Net sales in the three months ended June 30, 2012 were not significantly impacted by movements in foreign exchange rates.

In the six months ended June 30, 2012, net sales remained relatively consistent when compared to the same period in 2011, as higher sales of heavy duty diesel and automotive products were offset by a decline in sales of light duty diesel products, driven by lower demand in Europe.  Net sales in the six months ended June 30, 2012 were not significantly impacted by movements in foreign exchange rates.

Net income in the three and six months ended June 30, 2012, was higher primarily due to improved manufacturing performance and a decrease in air freight costs.  Movements in foreign exchange rates did not significantly impact the results of this segment in the three and six months ended June 30, 2012.

The Environmental Technologies segment sells to a concentrated customer base of catalyzer and emission control systems manufacturers.  Although our sales are to the emission control systems manufacturers, who then sell to automotive and diesel engine manufacturers, the use of our substrates and filters is generally required by the specifications of the automotive and diesel engine manufacturers.  For the three and six months ended June 30, 2012, three customers of the Environmental Technologies segment, which individually accounted for more than 10% of segment net sales, accounted for approximately 87% of total segment sales when combined.  While we are not aware of any significant customer credit issues with our direct customers, our near-term sales and profitability would be impacted if any individual customers were unable to continue to purchase our products.

Outlook:

In the third quarter of 2012, we expect sales to be consistent with the second quarter of 2012.

-36-

Specialty Materials

The following table provides net sales and net income for the Specialty Materials segment (in millions):

	Three months ended June 30,				% change	Six months ended June 30,				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales	$	296	$	283	5%	$	584	$	537	9%
Net income	$	34	$	23	48%	$	55	$	31	77%

Net sales for the three and six months ended June 30, 2012 increased in the Specialty Materials segment when compared to the same periods in 2011, driven by a significant increase in sales volume of Corning Gorilla Glass, offset partially by price declines.  Additionally, sales of large cover glass products in the first half of 2012 decreased due to the build-up of large cover glass television inventory in the supply chain in the first quarter of 2011 that did not repeat in 2012.  Movements in foreign exchange rates did not significantly impact net sales of this reportable segment in the second quarter and first half of 2012.

When compared to the same periods last year, the increase in net income for the three and six months ended June 30, 2012 was driven by the increase in sales of Corning Gorilla Glass, combined with the absence of large cover glass start-up and tank conversion costs incurred in the first half of 2011.  Net income for the three and six months ended June 30, 2012 was not significantly impacted from movements in foreign exchange rates when compared to the same periods in 2011.

For the three and six months ended June 30, 2012, two customers of the Specialty Materials segment, which individually accounted for more than 10% of segment net sales, accounted for 48% and 49%, respectively, of total segment sales when combined.

Outlook:

In the third quarter of 2012, Specialty Materials segment sales are anticipated to grow in the range of 10% to 15% when compared to the second quarter, reflecting improved Corning Gorilla Glass sales during the quarter.

Life Sciences

The following table provides net sales and net income for the Life Sciences segment (in millions):

	Three months ended June 30,				% change	Six months ended June 30				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales	$	162	$	155	5%	$	317	$	299	6%
Net income	$	11	$	15	(27)%	$	23	$	30	(23)%

Net sales for the three and six months ended June 30, 2012 increased when compared to the same periods last year, due to a small acquisition completed in the fourth quarter of 2011 and higher sales in the segment’s existing product lines.  Net sales in the three and six months ended June 30, 2012 were not significantly impacted by movements in foreign exchange rates.

For the three and six months ended June 30, 2012, net income declined when compared to the same periods in 2011 driven by the impact of higher raw materials costs and acquisition related operating expenses, which more than offset the favorable impact of the increase in net sales.  Net income in the second quarter and first half of 2012 was not significantly impacted by movements in foreign exchange rates when compared to the same periods in 2011.

-37-

For the three and six months ended June 30, 2012, two customers of the Life Sciences segment, which individually accounted for more than 10% of net sales, accounted for 45% and 42%, respectively, of net sales when combined.

Outlook:

In the third quarter of 2012, we expect net sales to be consistent with or up slightly when compared to the second quarter.

All Other

All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.”  This group is primarily comprised of development projects and results for new product lines.

The following table provides net sales and other data for All Other (in millions):

	Three months ended June 30,				% change	Six months ended June 30,				% change
	2012		2011		12 vs. 11	2012		2011		12 vs. 11
Net sales	$	1	$	1	0%	$	2	$	3	(33)%
Research, development and engineering expenses	$	29	$	24	21%	$	56	$	46	22%
Equity earnings of affiliated companies	$	9	$	2	350%	$	13	$	9	44%
Net loss	$	(16)	$	(20)	*	$	(36)	$	(35)	*

* The percentage change calculation is not meaningful.

This group is primarily comprised of development projects that involve the use of various technologies for new products such as advanced flow reactors, thin-film photovoltaics and adjacency businesses in pursuit of thin, strong glass.  This segment also includes results for certain corporate investments such as Samsung Corning Precision’s non-LCD glass businesses, Eurokera and Keraglass equity affiliates, which manufacture smooth cooktop glass/ceramic products, and Corsam, an equity affiliate established between Corning and Samsung Corning Precision to provide glass technology research.  Refer to Note 8 (Investments) for additional information about Samsung Corning Precision and related party transactions.

The results of this segment for the three and six months ended June 30, 2012 reflect a gain on the sale of assets in Samsung Corning Precision’s non-LCD glass business, offset by an increase in research, development, and engineering expenses for development projects, when compared to the same periods last year.

LIQUIDITY AND CAPITAL RESOURCES

Financing and Capital Structure

The following items impacted Corning’s financing and capital structure in the six months ended June 30, 2012 and 2011:

·   In the first quarter of 2012, we issued $500 million of 4.75% senior unsecured notes that mature on March 15, 2042 and $250 million of 4.70% senior unsecured notes that mature on March 15, 2037.  The net proceeds of $742 million will be used for general corporate purposes.

·   In the second quarter of 2011, a wholly-owned subsidiary entered into a credit facility that allows Corning to borrow up to Chinese Renminbi (RMB) 4.0 billion, or approximately $633 million when translated to United States dollars.  Corning may request advances during the eighteen month period beginning on June 30, 2011 (the “Availability Period”).  Corning will repay the aggregate principal amount and accrued interest outstanding at the end of the Availability Period in six installments, with the final payment due in August, 2016, five years from the date of the first advance.

-38-

Capital Spending

Capital spending totaled $853 million and $1.0 billion for the six months ended June 30, 2012 and 2011, respectively.  Spending in the first half of 2012 was driven primarily by capacity expansion projects in several of our reportable segments that were started in 2011.  We expect our 2012 capital spending to be $1.8 to $1.9 billion.  Approximately $900 million will be directed toward our Display Technologies segment, of which approximately $300 million is related to 2011 capital projects.

Cash Flows

Summary of cash flow data (in millions):

	Six months ended June 30,
	2012		2011
Net cash provided by operating activities	$	1,332	$	1,119
Net cash used in investing activities	$	(1,139)	$	(1,162)
Net cash provided by (used in) financing activities	$	260	$	(129)

Net cash provided by operating activities increased in the six months ended June 30, 2012 when compared to the same period last year, due to an increase in dividends received from affiliated companies and the impact of favorable movements in working capital.  These events were partially offset by higher pension contributions and the absence of the insurance payment received in 2011 for the remainder of our settlement of claims for business interruption and property damage occurring in 2009.

Net cash used in investing activities was lower in the six months ended June 30, 2012 when compared to the same period last year, due to the absence of acquisition spending and a decrease in capital spending, offset by our investment in affiliates and a net increase in short-term investments.

Net cash provided by financing activities in the six months ended June 30, 2012 increased when compared to the same period last year, driven primarily by the net proceeds received from the debt issuance of $886 million, offset somewhat by the repurchase of common stock and the increase in dividends paid to shareholders.

Dividends from Equity Companies

Corning Hungary Data Services LLC and Samsung Display Co., Ltd., as shareholders of Samsung Corning Precision, agreed to have Samsung Corning Precision increase its normal annual dividend to shareholders from 40% to 70% of its net income from the previous year, subject to the maintenance of minimum cash balances.  In the first quarter of 2012, we received a dividend from Samsung Corning Precision of approximately $500 million.

Management Assessment of Liquidity

We ended the second quarter of 2012 with approximately $6.3 billion of cash, cash equivalents, and short-term investments.  The Company has adequate sources of liquidity and we are confident in our ability to generate cash to meet existing or reasonably likely future cash requirements.  Our cash, cash equivalents, and short-term investments are held in various locations throughout the world and are generally unrestricted.  At June 30, 2012, approximately 65% of the consolidated amount was held outside of the U.S.  Almost all of the amounts held outside the U.S. are available for repatriation, subject to relevant tax consequences.  We utilize a variety of tax planning and financing strategies in an effort to ensure that our worldwide cash is available in those locations where it is needed.  We expect previously accumulated non-U.S. cash balances will remain outside of the U.S.  We expect that we will meet U.S. liquidity needs through future cash flows, use of U.S. cash balances, external borrowings, or some combination of these sources.

Realized gains and losses for the six months ended June 30, 2012 and 2011 were not significant.  From time to time, we may issue debt, the proceeds of which may be used to refinance certain debt maturities and for general corporate purposes.

During the six months ended June 30, 2012, we repurchased 31.1 million shares of common stock for $407 million as part of a $1.5 billion share repurchase program announced on October 5, 2011.  There were no repurchases in the first half of 2011.

-40-

We complete comprehensive reviews of our significant customers and their creditworthiness by analyzing their financial statements at least annually, and more frequently for customers where we have identified the potential for increased risk.  We closely monitor customer payment patterns and business developments that may signal possible customer credit issues.  We currently have not identified any potential material impact on our liquidity resulting from customer credit issues.

Our major source of funding for the remainder of 2012 and beyond will be our operating cash flow and our existing balances of cash, cash equivalents, short term investments, and proceeds from any issuances of debt.  We believe we have sufficient liquidity for the next several years to fund operations, our share repurchase program, acquisitions, the asbestos litigation, research and development, capital expenditures, scheduled debt repayments, and dividend payments.

Corning also has access to two credit facilities, a $1.0 billion unsecured committed revolving line of credit and a 4.0 billion Chinese Renminbi (RMB) credit agreement (approximately $633 million when translated to USD).  These two credit facilities include two financial covenants:  a leverage ratio and an interest coverage ratio.  The required leverage ratio, which measures debt to total capital, is a maximum of 50%.  At June 30, 2012 and December 31, 2011, our leverage using this measure was 13% and 10%, respectively.  The required interest coverage ratio, which is an adjusted earnings measure as defined by our facility, compared to interest expense, is a ratio of at least 3.5 times.  At June 30, 2012 and December 31, 2011, our interest coverage ratio using this measure was 41.7 times.  At June 30, 2012 and December 31, 2011, we were in compliance with both financial covenants.

Our debt instruments contain customary event of default provisions, which allow the lenders the option of accelerating all obligations upon the occurrence of certain events.  In addition, the majority of our debt instruments contain a cross default provision, whereby a default on one debt obligation of the Company in excess of a specified amount, also would be considered a default under the terms of another debt instrument.  As of June 30, 2012, we were in compliance with all such provisions.

Management is not aware of any known trends or any known demands, commitments, events or uncertainties that will result in or that are reasonably likely to result in a material increase or decrease in our liquidity.  In addition, other than items discussed, there are no known material trends, favorable or unfavorable, in our capital resources and no expected material changes in the mix and relative cost of such resources.

Off Balance Sheet Arrangements

There have been no material changes outside the ordinary course of business in our off balance sheet arrangements as disclosed in our 2011 Form 10-K under the caption “Off Balance Sheet Arrangements.”

Contractual Obligations

There have been no material changes outside the ordinary course of business in the contractual obligations disclosed in our 2011 Form 10-K under the caption “Contractual Obligations.”

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements requires management to make estimates and assumptions that affect amounts reported therein.  The estimates that required management’s most difficult, subjective or complex judgments are described in our 2011 Form 10-K and remain unchanged through the first six months of 2012.  For certain items, additional details are provided below.

-41-

Impairment of Assets Held for Use

We are required to assess the recoverability of the carrying value of long-lived assets when an indicator of impairment has been identified.  We review our long-lived assets in each quarter in which impairment indicators are present.  We must exercise judgment in assessing whether an event of impairment has occurred.

Manufacturing equipment includes certain components of production equipment that are constructed of precious metals, primarily platinum and rhodium.  These metals are not depreciated because they have very low physical losses and are repeatedly reclaimed and reused in our manufacturing process over a very long useful life.  Precious metals are reviewed for impairment as part of our assessment of long-lived assets.  This review considers all of the Company’s precious metals that are either in place in the production process; in reclamation, fabrication, or refinement in anticipation of re-use; or awaiting use to support increased capacity.  Precious metals are only acquired to support our operations and are not held for trading or other purposes.

At June 30, 2012 and December 31, 2011, the carrying value of precious metals was higher than the fair market value by $157 million and $304 million, respectively.  For these reporting periods, the undiscounted cash flow test shows that these precious metal assets, primarily in the Display Technologies segment, are recoverable as part of their asset groupings.  The potential for impairment exists in the future if negative events significantly decrease the cash flow of our segments.  Such events include, but are not limited to, a significant decrease in demand for products or a significant decrease in profitability in our Display Technologies or Specialty Materials segments.

NEW ACCOUNTING STANDARDS

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.  The ASU 2011-11 amendments require companies to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position.  ASU 2011-11 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years beginning on or after January 1, 2013, and interim periods within those annual fiscal years.  Corning does not expect adoption of this standard to have a material impact on its consolidated financial condition.

ENVIRONMENT

Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act, or by state governments under similar state laws, as a potentially responsible party for 18 hazardous waste sites.  Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise.  It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants.  At June 30, 2012, and December 31, 2011, Corning had accrued approximately $24 million (undiscounted) and $25 million (undiscounted), respectively, for the estimated liability for environmental cleanup and related litigation.  Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company’s liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures

As noted in our 2011 Form 10-K, we operate and conduct business in many foreign countries and as a result are exposed to fluctuations between the U.S. dollar and other currencies.  Volatility in the global financial markets could increase the volatility of foreign currency exchange rates which would, in turn, impact our sales and net income.  For a discussion of our exposure to market risk, refer to Part II, Item 1A, Risk Factors in this Quarterly Report on Form 10-Q and Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risks, contained in our 2011 Form 10-K.

ITEM 4.  CONTROLS AND PROCEDURES

Corning carried out an evaluation, under the supervision and with the participation of Corning’s management, including its chief executive officer and chief financial officer, of the effectiveness of the design and operation of Corning’s disclosure controls and procedures as of June 30, 2012, the end of the period covered by this report.  Based upon the evaluation, the chief executive officer and chief financial officer concluded that Corning’s disclosure controls and procedures are effective to ensure that information required to be disclosed by Corning in reports that it files or submits under the Securities Exchange Act of 1934 (the Exchange Act) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.  Corning’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by Corning in the reports that it files or submits under the Exchange Act is accumulated and communicated to Corning’s management, including Corning’s principal executive and principal financial officers, or other persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

During the fiscal quarter ended June 30, 2012, no change occurred in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Trade Secret Misappropriation Suits Concerning LCD Glass Technology.  On July 18, 2011, in China, Corning Incorporated filed suit in the Beijing Second Intermediate People’s Court against Hebei Dongxu Investment Group Co., Ltd., which changed its name to Dongxu Group Co., Ltd. (Dongxu) for misappropriation of certain trade secrets related to the fusion draw process for manufacturing glass substrates used in active matrix liquid crystal displays (LCDs).  Dongxu has filed an appeal to contest jurisdiction.  On July 18, 2011, in Korea, Corning Incorporated and Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) filed suits in the Daejeon District Court against Dongxu, one of its officers, and two other named individuals, for related trade secret misappropriation.  Samsung Corning Precision is an equity company of Corning and Samsung Electronics Co., Ltd., which uses Corning LCD glass technology under license agreements with Corning.  In these actions, Corning is seeking orders restraining Dongxu from using, disclosing, or permitting others to use, misappropriated Corning LCD glass manufacturing technology.  Two of the individuals named in the Korean suit were previously convicted in Seoul Southern District Court on January 22, 2009, for the theft of certain Corning LCD glass technology that was being used by Samsung Corning Precision.  On February 8, 2012, the Daejeon District Court entered a judgment in the civil case against the two individuals and an officer of Dongxu.  The Dongxu officer has filed an appeal.

Grand Jury Subpoena.  In March of 2012, Corning received a grand jury subpoena issued in the United States District Court for the Eastern District of Michigan from the U.S. Department of Justice in connection with an investigation into conduct relating to possible antitrust law violations involving certain automotive products, including catalytic converters, diesel particulate filters, substrates and monoliths.  The subpoena requires Corning to produce certain documents located within the United States to the Department of Justice.  Corning’s policy is to comply with all laws and regulations, including all antitrust and competition laws.  Antitrust investigations can result in significant penalties being imposed by the antitrust authorities.  Currently Corning cannot estimate the ultimate financial impact, if any, resulting from the investigation.  Such potential impact, if an antitrust violation by Corning is found, could however, be material to the results of operations of Corning in a particular period.

Debt [Abstract]

Debt

3.      Debt

Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $3.6 billion at June 30, 2012 and $2.6 billion at December 31, 2011.  The Company measures the fair value of its long-term debt using Level 2 inputs based primarily on current market yields for its existing debt traded in the secondary market.

2012

In the first quarter of 2012, we issued $250 million of 4.70% senior unsecured notes and $500 million of 4.75% senior unsecured notes for net proceeds of approximately $247 million and $495 million, respectively.  The 4.70% notes mature on March 15, 2037 and the 4.75% notes mature on March 15, 2042.

2011

In the second quarter of 2011, a wholly-owned subsidiary entered into a credit facility that allows Corning to borrow up to Chinese Renminbi (RMB) 4.0 billion, or approximately $633 million when translated to United States dollars.  Corning may request advances during the eighteen month period beginning on June 30, 2011 (the "Availability Period").   Corning will repay the aggregate principal amount and accrued interest outstanding at the end of the Availability Period in six installments, with the final payment due in August, 2016, five years from the date of the first advance.

Commitments, Contingencies, and Guarantees

2.      Commitments, Contingencies, and Guarantees

Asbestos Litigation

Pittsburgh Corning Corporation.  Corning and PPG Industries, Inc. (PPG) each own 50% of the capital stock of Pittsburgh Corning Corporation (PCC).  Over a period of more than two decades, PCC and several other defendants have been named in numerous lawsuits involving claims alleging personal injury from exposure to asbestos.  On April 16, 2000, PCC filed for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Western District of Pennsylvania.  Corning, with other relevant parties, has been involved in ongoing efforts to develop a Plan of Reorganization that would resolve the concerns and objections of the relevant parties.  A proposed PCC plan of reorganization (Amended PCC Plan) filed in the U.S. Bankruptcy Court for the Western District of Pennsylvania was not confirmed by the Court.  Further changes to the Amended PCC Plan are expected to be filed by August 20, 2012.  Corning also has an equity interest in Pittsburgh Corning Europe N.V. (PCE), a Belgian Corporation that is a component of the Company's proposed resolution of the PCC asbestos litigation.  At June 30, 2012 and December 31, 2011, the fair value of PCE significantly exceeded its carrying value of $136 million and $138 million, respectively.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning.  Corning has recorded in its estimated asbestos litigation liability an additional $150 million for the approximately 9,900 current non-PCC cases alleging injuries from asbestos, and for any future non-PCC cases.  The liability for the Amended PCC Plan and the non-PCC asbestos claims was estimated to be $663 million at June 30, 2012, compared with an estimate of the liability of $657 million at December 31, 2011.  In the three and six months ended June 30, 2012, Corning recorded asbestos litigation expense of $5 million and $6 million, respectively.  In the three and six months ended June 30, 2011, Corning recorded asbestos litigation expense of $5 million and $10 million, respectively.  The entire obligation is classified as a non-current liability as installment payments for the cash portion of the obligation are not planned to commence until more than 12 months after the Amended PCC Plan becomes effective and the PCE portion of the obligation will be fulfilled through the direct contribution of Corning's investment in PCE (currently recorded as a non-current other equity method investment).

Other Commitments and Contingencies

In the normal course of our business, we do not routinely provide significant third-party guarantees.  Generally, any third party guarantees provided by Corning are limited to certain financial guarantees including stand-by letters of credit and performance bonds, and the incurrence of contingent liabilities in the form of purchase price adjustments related to attainment of milestones.  When provided, these guarantees have various terms, and none of these guarantees are individually significant.

We have agreed to provide a credit facility to Dow Corning Corporation (Dow Corning).  The funding of the Dow Corning credit facility will be required only if Dow Corning is not otherwise able to meet its scheduled funding obligations in its confirmed Bankruptcy Plan.  We believe a significant majority of these guarantees and contingent liabilities will expire without being funded.

As of June 30, 2012 and December 31, 2011, contingent guarantees totaled a notional value of $140 million and $170 million, respectively.  We believe a significant majority of these contingent guarantees will expire without being funded.  We also were contingently liable for purchase obligations of $75 million and $72 million, at June 30, 2012 and December 31, 2011, respectively.

Product warranty liability accruals were $22 million at June 30, 2012 and $23 million at December 31, 2011.

Corning is a defendant in various lawsuits, including environmental litigation, product-related suits, the Dow Corning and PCC matters, and is subject to various claims which arise in the normal course of business.  In the opinion of management, the likelihood that the ultimate disposition of these matters will have a material adverse effect on Corning's consolidated financial position, liquidity, or results of operations, is remote.

In March of 2012, Corning received a grand jury subpoena issued in the United States District Court for the Eastern District of Michigan from the U.S. Department of Justice in connection with an investigation into conduct relating to possible antitrust law violations involving certain automotive products, including catalytic converters, diesel particulate filters, substrates and monoliths. Antitrust investigations can result in significant penalties being imposed by the antitrust authorities. Currently Corning can not estimate the ultimate financial impact, if any, resulting from the investigation.  Such potential impact, if an antitrust violation by Corning is found, could however, be material to the results of operations of Corning in a particular period.

Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act, or by state governments under similar state laws, as a potentially responsible party for 18 hazardous waste sites.  Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise.  It is Corning's policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants.  At June 30, 2012, and December 31, 2011, Corning had accrued approximately $24 million (undiscounted) and $25 million (undiscounted), respectively, for the estimated liability for environmental cleanup and related litigation.  Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company's liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

Reportable Segments [Abstract]

Reportable Segments

16.      Reportable Segments

Our reportable segments are as follows:

·   Display Technologies – manufactures liquid crystal display (LCD) glass for flat panel displays.

·   Telecommunications – manufactures optical fiber and cable, and hardware and equipment components for the telecommunications industry.

·   Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.  This reportable segment is an aggregation of our Automotive and Diesel operating segments as these two segments share similar economic characteristics, products, customer types, production processes and distribution methods.

·   Specialty Materials – manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for unique customer needs.

·   Life Sciences – manufactures glass and plastic consumables for scientific applications.

All other segments that do not meet the quantitative threshold for separate reporting are grouped as "All Other."  This group is primarily comprised of development projects and results for new product lines.

We prepared the financial results for our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions.  We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment's net income.  We have allocated certain common expenses among segments differently than we would for stand-alone financial information prepared in accordance with U.S. GAAP.  Segment net income may not be consistent with measures used by other companies.  The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements.

(1) Depreciation expense for Corning's reportable segments includes an allocation of depreciation of corporate property not specifically identifiable to a segment.

(2) Research, development, and engineering expenses include direct project spending that is identifiable to a segment.

(3) Many of Corning's administrative and staff functions are performed on a centralized basis.  Where practicable, Corning charges these expenses to segments based upon the extent to which each business uses a centralized function.  Other staff functions, such as corporate finance, human resources and legal, are allocated to segments, primarily as a percentage of sales.

A reconciliation of reportable segment net income to consolidated net income follows (in millions):

	Three months ended June 30,				Six months ended June 30,

Other corporate items		27		37		60		96
Net income	$	462	$	755	$	924	$	1,503

(1) Net financing costs include interest income, interest expense, and interest costs and investment gains associated with benefit plans.

(2) Primarily represents the equity earnings of Dow Corning Corporation.

(3) In the three and six months ended June 30, 2012, Corning recorded a charge of $5 million and $6 million, respectively, to adjust the asbestos liability for the change in value of the components of the Amended PCC Plan.In the three and six months ended June 30, 2011, Corning recorded a charge of $5 million and $10 million, respectively, to adjust the asbestos liability for the change in value of the components of the Amended PCC Plan.

In the Telecommunications operating segment, assets increased from $1.2 billion at December 31, 2011 to $1.4 billion at June 30, 2012.  The increase is due primarily to increase of capital expenditures of approximately $170 million.

The sales of each of our reportable segments are concentrated across a relatively small number of customers.  In the second quarter of 2012, the following number of customers, which individually accounted for 10% or more of each segment's sales, represented the following concentration of segment sales:

·   In the Display Technologies segment, 4 customers accounted for 78% of total segment sales.

·   In the Telecommunications segment, 1 customer accounted for 12% of total segment sales.

·   In the Environmental Technologies segment, 3 customers accounted for 87% of total segment sales.

·   In the Specialty Materials segment, 2 customers accounted for 48% of total segment sales.

·   In the Life Sciences segment, 2 customers accounted for 45% of total segment sales.

In the first half of 2012, the following number of customers, which individually accounted for 10% or more of each segment's sales, represented the following concentration of segment sales:

·   In the Display Technologies segment, 4 customers accounted for 79% of total segment sales.

·   In the Telecommunications segment, 1 customer accounted for 12% of total segment sales.

·   In the Environmental Technologies segment, 3 customers accounted for 87% of total segment sales.

·   In the Specialty Materials segment, 2 customers accounted for 49% of total segment sales.

·   In the Life Sciences segment, 2 customers accounted for 42% of total segment sales.

A significant amount of specialized manufacturing capacity for our Display Technologies segment is concentrated in Asia.  It is at least reasonably possible that the operation of a facility could be disrupted.  Due to the specialized nature of the assets, it would not be possible to find replacement capacity quickly.  Accordingly, loss of these facilities could produce a near-term severe impact on our display business and the Company as a whole.

Corning and certain of its domestic subsidiaries offer postretirement plans that provide health care and life insurance benefits for retirees and eligible dependents.  Certain employees may become eligible for such postretirement benefits upon reaching retirement age and service requirements.  For current retirees (including surviving spouses) and active employees eligible for the salaried retiree medical program, we placed a "cap" on the amount we will contribute toward retiree medical coverage in the future.  The cap equals 120% of our 2005 contributions toward retiree medical benefits.  Once our contributions toward salaried retiree medical costs reach this cap, impacted retirees will have to pay the excess amount in addition to their regular contributions for coverage.  This cap was attained for post-65 retirees in 2008 and has impacted their contribution rate in 2009 and going forward.  The pre-65 retirees triggered the cap in 2010, which has impacted their contribution rate in 2011 and going forward.  Furthermore, employees hired or rehired on or after January 1, 2007 will be eligible for Corning retiree medical upon retirement; however, these employees will pay 100% of the cost.

Hedging Activities

6 Months Ended

Jun. 30, 2012

Hedging Activities [Abstract]

Hedging Activities

12.      Hedging Activities

Corning operates in many foreign countries and as a result is exposed to movements in foreign currency exchange rates.  The areas in which exchange rate fluctuations affect us include:

·   Financial instruments and transactions denominated in foreign currencies, which impact earnings; and

·   The translation of net assets in foreign subsidiaries for which the functional currency is not the U.S. dollar, which impacts our net equity.

Our most significant foreign currency exposures relate to the Japanese yen, Korean won, New Taiwan dollar and the Euro.  We manage our foreign currency exposures, which include forecasted transactions, primarily by entering into foreign exchange forward contracts with durations of generally 18 months or less to hedge foreign currency risk.  The hedges are scheduled to mature coincident with the timing of the underlying foreign currency commitments and transactions.  The objective of these contracts is to neutralize the impact of exchange rate movements on our operating results.

The forward and option contracts we use in managing our foreign currency exposures contain an element of risk in that the counterparties may be unable to meet the terms of the agreements.  However, we minimize this risk by limiting the counterparties to a diverse group of highly-rated major domestic and international financial institutions with which we have other financial relationships.  We are exposed to potential losses in the event of non-performance by these counterparties.  However, we do not expect to record any losses as a result of such counterparty default.  Neither we nor our counterparties are required to post collateral for these financial instruments.

Cash Flow Hedges

Our cash flow hedging activities utilize foreign exchange forward contracts to reduce the risk that movements in exchange rates will adversely affect the eventual net cash flows resulting from the sale of products to foreign customers and purchases from foreign suppliers.  Our cash flow hedging activity also utilizes interest rate forwards to reduce the risk of changes in benchmark interest rate from the probable forecasted issuance of debt.  Corning uses a regression analysis to monitor the effectiveness of its cash flow hedges both prospectively and retrospectively.  Corning defers net gains and losses from cash flow hedges into accumulated other comprehensive income on the consolidated balance sheet until such time as the hedged item impacts earnings.  At June 30, 2012, the amount of net gain expected to be reclassified into earnings within the next 12 months is $15 million.

Undesignated Hedges

Corning uses other foreign exchange forward contracts that are not designated as hedging instruments for accounting purposes.  The undesignated hedges limit exposures to foreign currency fluctuations related to certain monetary assets, monetary liabilities and net earnings in foreign currencies.

The following tables summarize the notional amounts and respective fair values of Corning's derivative financial instruments for June 30, 2012 and December 31, 2011 (in millions):

			Asset derivatives			Liability derivatives

Total long-term investments	$	54	$	57	$	35	$	35

We do not intend to sell, nor do we believe it is more likely than not that we would be required to sell, the long-term investment asset-backed securities (which are collateralized by mortgages) before recovery of their amortized cost basis.  It is possible that a significant degradation in the delinquency or foreclosure rates in the underlying assets could cause further temporary or other-than-temporary impairments in the future.

The following table summarizes the maturities at market value of available-for-sale securities at June 30, 2012 (in millions):

Less than one year	$1,031
Due in 1-5 years	306
Due in 5-10 years
Due after 10 years (1)	35
Total	$1,372

(1) Includes $35 million of asset-based securities that mature over time and are being reported at their final maturity dates.

Unrealized gains and losses, net of tax, are computed on a specific identification basis and are reported as a separate component of accumulated other comprehensive loss in shareholders' equity until realized.

The following tables provide the fair value and gross unrealized losses of the Company's investments aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2012 and December 31, 2011 (in millions):

As of June 30, 2012 and December 31, 2011, for securities that have credit losses, an other than temporary impairment loss of $15 and $18 million, respectively, is recognized in accumulated other comprehensive loss.

Proceeds from sales and maturities of short-term investments totaled $1.0 billion and $1.9 billion for the six months ended June 30, 2012 and 2011, respectively.

New Accounting Standards

New Accounting Standards

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.  The ASU 2011-11 amendments require companies to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position.  ASU 2011-11 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years beginning on or after January 1, 2013, and interim periods within those annual fiscal years.  Corning does not expect adoption of this standard to have a material impact on its consolidated financial condition.

Fair Value Measurements [Abstract]

Fair Value Measurements

13.      Fair Value Measurements

Fair value standards under U.S. GAAP define fair value, establish a framework for measuring fair value in applying generally accepted accounting principles, and require disclosures about fair value measurements.  The standards also identify two kinds of inputs that are used to determine the fair value of assets and liabilities: observable and unobservable.  Observable inputs are based on market data or independent sources while unobservable inputs are based on the Company's own market assumptions.  Once inputs have been characterized, the inputs are prioritized into one of three broad levels (provided in the table below) used to measure fair value.

Fair value standards apply whenever an entity is measuring fair value under other accounting pronouncements that require or permit fair value measurement and require the use of observable market data when available.  As of June 30, 2012 and December 31, 2011, the Company did not have any financial assets or liabilities that were measured using unobservable (or Level 3) inputs.

The following tables provide fair value measurement information for the Company's major categories of financial assets and liabilities measured on a recurring basis (in millions):

		Fair value measurements at reporting date using

Corning transfers of machinery and equipment to Samsung Corning Precision at cost (1)	$	25	$	27	$	40	$	61

(1) Corning purchases machinery and equipment on behalf of Samsung Corning Precision to support its capital expansion initiatives.  The machinery and equipment are transferred to Samsung Corning Precision at our cost basis.

As of June 30, 2012, balances due from Samsung Corning Precision were $12 million and balances due to Samsung Corning Precision were $30 million.  As of December 31, 2011, balances due from Samsung Corning Precision were $16 million and balances due to Samsung Corning Precision were $11 million.

Corning owns 50% of Samsung Corning Precision.  Samsung Display Co., Ltd. owns 43% and other shareholders own the remaining 7%.

In June 2011, the Korean tax authorities completed an audit of Samsung Corning Precision.  As a result, Samsung Corning Precision was issued a pre-assessment of approximately $46 million for an asserted underpayment of withholding tax on dividends paid from September 2006 through March 2009.  In April 2011, we appealed for a reversal of the assessment. In October 2011, that appeal was denied and a formal assessment was issued.  Corning paid the assessment in the fourth quarter of 2011, allowing us to appeal to the Korean Tax Tribunal.  Once a ruling from the Korean Tax Tribunal is received, Corning may continue the Korean appeals process and/or access the Competent Authority under the U.S./Korea tax treaty, which allows the U.S. tax authorities' involvement in resolving the matter.  Samsung Corning Precision and Corning believe it is more likely than not we will receive a favorable ruling when all of the available appeals have been exhausted.

Dow Corning Corporation (Dow Corning)

Dow Corning is a U.S.-based manufacturer of silicone products.  Dow Corning's results of operations follow (in millions):

	Three months ended June 30,				Six months ended June 30

Related Party Transactions:

Dividends received from Dow Corning			$	65			$	180

Amounts owed to Dow Corning totaled $1 million as of June 30, 2012.  At December 31, 2011, amounts owed to Dow Corning were not significant.

At June 30, 2012, Dow Corning's marketable securities included approximately $138 million of auction rate securities, net of a temporary impairment of $6 million.

Corning and The Dow Chemical Company (Dow Chemical) each own 50% of the common stock of Dow Corning.  In May 1995, Dow Corning filed for bankruptcy protection to address pending and claimed liabilities arising from many thousands of breast implant product lawsuits.  On June 1, 2004, Dow Corning emerged from Chapter 11 with a Plan of Reorganization (the Plan) which provided for the settlement or other resolution of implant claims.  Under the terms of the Plan, Dow Corning has established and is funding a Settlement Trust and a Litigation Facility to provide a means for tort claimants to settle or litigate their claims.  Inclusive of insurance, Dow Corning has paid approximately $1.7 billion to the Settlement Trust.

As of June 30, 2012, Dow Corning had recorded a reserve for breast implant litigation of $1.6 billion.  As a separate matter arising from the bankruptcy proceedings, Dow Corning is defending claims asserted by a number of commercial creditors who claim additional interest at default rates and enforcement costs, during the period from May 1995 through June 2004.  As of June 30, 2012, Dow Corning has estimated the liability to commercial creditors to be within the range of $88 million to $287 million.  As Dow Corning management believes no single amount within the range appears to be a better estimate than any other amount within the range, Dow Corning has recorded the minimum liability within the range.  Should Dow Corning not prevail in this matter, Corning's equity earnings would be reduced by its 50% share of the amount in excess of $88 million, net of applicable tax benefits.

Variable Interest Entities

For variable interest entities, we routinely assess the terms of our interest in each entity to determine if we are the primary beneficiary as prescribed by U.S. GAAP.  We currently have three variable interest entities that are not considered significant to Corning's consolidated financial statements.  Corning does not have retained interests in assets transferred to any unconsolidated entity that serves as credit, liquidity or market risk support to such entity.

4.      Income Taxes

Our provision for income taxes and the related effective income tax rates were as follows (in millions):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Provision for income taxes	$	(93)	$	(123)	$	(204)	$	(237)
Effective tax rate		16.8%		14.0%		18.1%		13.6%

For the three and six months ended June 30, 2012, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of nonconsolidated affiliates reported in the financials net of tax;

·   The expiration of favorable U.S. tax provisions; and

·   The benefit of tax incentives in foreign jurisdictions, primarily Taiwan.

For the three and six months ended June 30, 2011, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

·   Rate differences on income (loss) of consolidated foreign companies;

·   The impact of equity in earnings of affiliated companies; and

·   The benefit of tax incentives in foreign jurisdictions, primarily Taiwan.

Certain foreign subsidiaries in China and Taiwan are operating under tax holiday arrangements.  The nature and extent of such arrangements vary, and the benefits of such arrangements phase out through 2015 according to the specific terms and schedules of the relevant taxing jurisdictions. The impact of the tax holiday on our effective tax rate is a reduction in the rate of 1.4 and 1.3 percentage points for the three months ended June 30, 2012 and 2011, respectively.  The impact of the tax holiday on our effective tax rate is a reduction in the rate of 1.4 percentage points for the six months ended June 30, 2012 and 2011.

While we expect the amount of unrecognized tax benefits to change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or our financial position.

Share-Based Compensation

Share-Based Compensation [Abstract]

Share-Based Compensation

14.      Share-based Compensation

Stock Compensation Plans

The Company measures and recognizes compensation cost for all share-based payment awards made to employees and directors based on estimated fair values.  Fair values for stock options were estimated using a multiple-point Black-Scholes valuation model.  Share-based compensation cost was approximately $16 million and $22 million for the three months ended June 30, 2012 and 2011, respectively, and approximately $40 million and $45 million for the six months ended June 30, 2012 and 2011, respectively.  Amounts for all periods presented included (1) employee stock options, (2) time-based restricted stock and restricted stock units, and (3) performance-based restricted stock and restricted stock units.

Stock Options

Our Stock Option Plans provide non-qualified and incentive stock options to purchase authorized but unissued shares or treasury shares at the market price on the grant date and generally become exercisable in installments from one to five years from the grant date.  The maximum term of non-qualified and incentive stock options is 10 years from the grant date.

The following table summarizes information concerning stock options outstanding including the related transactions under the Stock Option Plans for the six months ended June 30, 2012:

	Number of Shares (in thousands)	Weighted- Average Exercise Price	Weighted- Average Remaining Contractual Term in Years	Aggregate Intrinsic Value (in thousands)
Options Outstanding as of December 31, 2011	65,027	$15.91
Granted	7,623	12.99
Exercised	(2,839)	6.76
Forfeited and Expired	(1,162)	18.07
Options Outstanding as of June 30, 2012	68,649	15.93	5.05	94,692
Options Exercisable as of June 30, 2012	55,406	15.89	4.12	94,459

The aggregate intrinsic value (market value of stock less option exercise price) in the preceding table represents the total pretax intrinsic value, based on the Company's closing stock price on June 30, 2012, which would have been received by the option holders had all option holders exercised their options as of that date.

As of June 30, 2012, there was approximately $41 million of unrecognized compensation cost related to stock options granted under the Plans.  The cost is expected to be recognized over a weighted-average period of two years.  Compensation cost related to stock options was approximately $21 million and $25 million for the six months ended June 30, 2012 and 2011, respectively, and approximately $9 million and $13 million for the three months ended June 30, 2012 and 2011 respectively.

Proceeds received from the exercise of stock options were $19 million and $73 million for the six months ended June 30, 2012 and 2011, respectively and $3 million and $9 million for the three months ended June 30, 2012 and 2011, respectively.  Proceeds received from the exercise of stock options were included in financing activities on the Company's Consolidated Statements of Cash Flows.  The total intrinsic value of options exercised for the six months ended June 30, 2012 and 2011 was approximately $20 million and $68 million, and $5 million and $6 million for the three months ended June 30, 2012 and 2011, respectively, which is currently deductible for tax purposes. However, these tax benefits were not recognized due to net operating loss carryforwards available to the Company.  Refer to Note 4 (Income Taxes) to the consolidated financial statements.

The following inputs were used for the valuation of option grants under our Stock Option Plans:

	Three months ended June 30,		Six months ended June 30,
	2012	2011	2012	2011
Expected volatility	48%	47-48%	48-49%	47-48%
Weighted-average volatility	48%	47%	48-49%	47-48%
Expected dividends	2.28%	1.06%	2.28-2.33%	1.1%
Risk-free rate	0.9-1.2%	1.9-2.4%	0.9-1.3%	1.9-2.7%
Average risk-free rate	1.2%	2.4%	1.2-1.3%	2.4-2.6%
Expected term (in years)	5.7-7.1	5.1-6.7	5.7-7.1	5.1-6.7
Pre-vesting departure rate	0.4-4.2%	0.4-3.9%	0.4-4.2%	0.4-3.9%

Expected volatility is based on a blended approach defined as the weighted average of the short-term implied volatility, the most recent volatility for the period equal to the expected term and the most recent 15-year historical volatility.  The expected term assumption is the period of time the options are expected to be outstanding, and is calculated using a combination of historical exercise experience adjusted to reflect the current vesting period of options being valued, and partial life cycles of outstanding options.  The risk-free rate assumption is the implied rate for a zero-coupon U.S. Treasury bond with a term equal to the option's expected term.  The ranges given above result from different groups of employees exhibiting different exercise behavior.

Incentive Stock Plans

The Corning Incentive Stock Plan permits stock grants, either determined by specific performance goals or issued directly, in most instances, subject to the possibility of forfeiture and without cash consideration.  Shares under the Incentive Stock Plan are granted at the market price on the grant date, contingently vest over a period of 1 to 10 years, and have contractual lives of 1 to 10 years.

The fair value of each restricted stock grant under the Incentive Stock Plans was estimated on the date of grant for performance-based grants assuming that performance goals will be achieved.  The expected term for grants under the Incentive Stock Plans is 1 to 10 years.

Time-Based Restricted Stock and Restricted Stock Units:

Time-based restricted stock and restricted stock units are issued by the Company on a discretionary basis, and are payable in shares of the Company's common stock upon vesting.  The fair value is based on the market price of the Company's stock on the grant date.  Compensation cost is recognized over the requisite vesting period and adjusted for actual forfeitures before vesting.

The following table represents a summary of the status of the Company's non-vested time-based restricted stock and restricted stock units as of December 31, 2011, and changes which occurred during the six months ended June 30, 2012:

	Shares (000's)	Weighted Average Grant-Date Fair Value
Non-vested shares at December 31, 2011	4,104	$	18.16
Granted	1,953		13.09
Vested	(411)		21.08
Forfeited	(65)		15.16
Non-vested shares at June 30, 2012	5,581	$	16.20

As of June 30, 2012, there was approximately $32 million of unrecognized compensation cost related to non-vested time-based restricted stock compensation arrangements granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 1.8 years.  Compensation cost related to time-based restricted stock and restricted stock units was approximately $17 million and $16 million for the six months ended June 30, 2012 and 2011, respectively, and $7 million for the three months ended June 30, 2012 and 2011.

Performance-Based Restricted Stock and Restricted Stock Units:

Performance-based restricted stock and restricted stock units are earned upon the achievement of certain targets, and are payable in shares of the Company's common stock upon vesting, typically over a three-year period.  The fair value is based on the market price of the Company's stock on the grant date and assumes that the target payout level will be achieved.  Compensation cost is recognized over the requisite vesting period and adjusted for actual forfeitures before vesting.  During the performance period, compensation cost may be adjusted based on changes in the expected outcome of the performance-related target.

The following table represents a summary of the status of the Company's non-vested performance-based restricted stock and restricted stock units as of December 31, 2011, and changes which occurred during the six months ended June 30, 2012:

	Shares (000's)	Weighted- Average Grant-Date Fair Value
Non-vested restricted stock and restricted stock units at December 31, 2011	5,134	$	8.67
Vested	(5134)		8.67
Non-vested restricted stock and restricted stock units at June 30, 2012	0	$	0

The performance-based restricted stock and restricted stock unit compensation program was terminated in 2010.  All performance-based restricted stock and stock units are vested as of June 30, 2012.

As of June 30, 2012, there is no unrecognized compensation cost related to non-vested performance-based restricted stock and restricted stock units compensation arrangements granted under the Plan.  Compensation cost related to performance-based restricted stock and restricted stock units was approximately $2 million and $4 million for the six months ended June 30, 2012 and 2011, respectively, and $2 million for the three months ended June 30, 2011.
