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, 2010 (2010 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.

Fair Value Measurements

Major categories of financial assets and liabilities, including short-term investments, other assets and derivatives are measured at fair value on a recurring basis.  Certain assets and liabilities including long-lived assets, goodwill, asset retirement obligations, and cost and equity investments are measured at fair value on a nonrecurring basis.

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

Other Income, Net

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

	Three months ended September 30,				Nine months ended September 30,

New Accounting Standards

In May, 2011, the FASB issued Accounting Standards Update No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.  This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRS.  ASU 2011-04 is required to be applied prospectively in interim and annual periods beginning after December 15, 2011.  Early application is not permitted.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In June, 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income.  This statement requires companies to present the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements of net income and other comprehensive income.  This statement is effective for interim and annual periods beginning after December 15, 2011.  Early adoption is permitted and the amendments in this update will be applied retrospectively.  Corning will adopt this standard in the first quarter of 2012.

In September 2011, FASB issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment.  This update simplifies how an entity tests goodwill for impairment.  It provides an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test.  Given this option, an entity no longer would be required to calculate the fair value of a reporting unit unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount.  The amendments will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.  Early adoption is permitted.  Corning will early adopt this standard during its fourth quarter impairment review process.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In September 2011, the FASB issued Accounting Standards Update No. 2011-09, Compensation—Retirement Benefits—Multiemployer Plans (Subtopic 715-80): Disclosures about an Employer’s Participation in a Multiemployer Plan.  The ASU 2011-09 amendments require additional disclosures about an employer's participation in a multiemployer plan.  ASU 2011-09 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years ending after December 15, 2011, with early adoption permitted.  Corning will not early adopt this standard and does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

3.      Commitments and Contingencies

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.  At the time PCC filed for bankruptcy protection, there were approximately 11,800 claims pending against Corning in state court lawsuits alleging various theories of liability based on exposure to PCC’s asbestos products and typically requesting monetary damages in excess of one million dollars per claim.  Corning has defended those claims on the basis of the separate corporate status of PCC and the absence of any facts supporting claims of direct liability arising from PCC’s asbestos products.  Corning is also currently involved in approximately 10,200 other cases (approximately 38,600 claims) alleging injuries from asbestos and similar amounts of monetary damages per case.  Those cases have been covered by insurance without material impact to Corning to date.  As described below, several of Corning’s insurance carriers have filed a legal proceeding concerning the extent of any insurance coverage for these claims.  Asbestos litigation is inherently difficult, and past trends in resolving these claims may not be indicators of future outcomes.

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 courts and parties.  In 2003, a plan was agreed to by various parties (the 2003 Plan), but, on December 21, 2006, the Bankruptcy Court issued an order denying the confirmation of that 2003 Plan.  On January 29, 2009, an amended plan of reorganization (the Amended PCC Plan) – which addressed the issues raised by the Court when it denied confirmation of the 2003 Plan – was filed with the Bankruptcy Court.

The proposed resolution of PCC asbestos claims under the Amended PCC Plan would have required Corning to contribute its equity interests in PCC and Pittsburgh Corning Europe N.V. (PCE), a Belgian corporation, and to contribute a fixed series of payments, recorded at present value.  Corning would have had the option to use its shares rather than cash to make these payments, but the liability would have been fixed by dollar value and not the number of shares.  The Amended PCC Plan would, originally, have required Corning to make (1) one payment of $100 million one year from the date the Amended PCC Plan becomes effective and certain conditions are met and (2) five additional payments of $50 million, on each of the five subsequent anniversaries of the first payment, the final payment of which is subject to reduction based on the application of credits under certain circumstances.  Documents were filed with the Bankruptcy Court further modifying the Amended PCC Plan by reducing Corning’s initial payment by $30 million and reducing its second and fourth payments by $15 million each.  In return, Corning would relinquish its claim for reimbursement of its payments and contributions under the Amended PCC Plan from the insurance carriers involved in the bankruptcy proceeding with certain exceptions.

-8-

On June 16, 2011, the Court entered an Order denying confirmation of the Amended PCC Plan.  The Court’s memorandum opinion accompanying the order rejected some objections to the Amended PCC Plan and made suggestions regarding modifications to the Amended PCC Plan that would allow the Plan to be confirmed.  Corning and other parties have filed a motion for reconsideration, objecting to certain points of this order.  Certain parties to the proceeding filed specific plan modifications in response to the Court’s opinion and Corning supported these filings.  Objections to the modifications are to be filed by October 28, 2011 and responses to the objections by November 16, 2011.  The Court has set a hearing on the objections for November 30, 2011.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning.  Corning has recorded an additional $150 million for such claims in its estimated asbestos litigation liability.  The liability for non-PCC claims was estimated based upon industry data for asbestos claims since Corning does not have recent claim history due to the injunction issued by the Bankruptcy Court.  The estimated liability represents the undiscounted projection of claims and related legal fees over the next 20 years.  The amount may need to be adjusted in future periods as more data becomes available.

The liability for the Amended PCC Plan and the non-PCC asbestos claims was estimated to be $649 million at September 30, 2011, compared with an estimate of the liability of $633 million at December 31, 2010.  In the three and nine months ended September 30, 2011, Corning recorded asbestos litigation expense of $5 million and $15 million, respectively.  In the three months and nine months ended September 30, 2010, Corning recorded asbestos litigation expense of $6 million and $13 million, respectively.  In addition, during the first quarter of 2010, Corning recorded a $54 million credit to the asbestos litigation reserve related to the change in terms of the proposed settlement of the PCC asbestos claims.  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).

The Amended PCC Plan with the modifications addressing issues raised by the Court’s June 16 opinion remains subject to a number of contingencies.  Payment of the amounts required to fund the Amended PCC Plan from insurance and other sources are subject to a number of conditions that may not be achieved.  The approval of the (further modified) Amended PCC Plan by the Bankruptcy Court is not certain and faces objections by some parties.  If the modified Amended PCC Plan is approved by the Bankruptcy Court, that approval will be subject to appeal.  For these and other reasons, Corning’s liability for these asbestos matters may be subject to changes in subsequent quarters.  The estimate of the cost of resolving the non-PCC asbestos claims may also be subject to change as developments occur.  Management continues to believe that the likelihood of the uncertainties surrounding these proceedings causing a material adverse impact to Corning’s financial statements is remote.

Several of Corning’s insurers have commenced litigation in state courts for a declaration of the rights and obligations of the parties under insurance policies, including rights that may be affected by the potential resolutions described above.  Corning is vigorously contesting these cases.  Management is unable to predict the outcome of this insurance litigation and therefore cannot estimate the range of any possible loss.

Other Commitments and Contingencies

In the normal course of our business, we do not routinely provide significant third-party guarantees.  When provided, these guarantees have various terms, and none of these guarantees are individually significant.  Generally, 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.  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.

-9-

As of September 30, 2011 and December 31, 2010, contingent guarantees totaled a notional value of $176 million and $230 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 $265 million and $408 million, at September 30, 2011 and December 31, 2010, respectively.

Product warranty liability accruals were $25 million at September 30, 2011 and $24 million at December 31, 2010.

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.

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 September 30, 2011, and December 31, 2010, Corning had accrued approximately $30 million (undiscounted) 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.

4.      Debt

Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $2.6 billion at September 30, 2011 and $2.4 billion at December 31, 2010.

Third Quarter

In the third quarter of 2011, Corning borrowed approximately $34 million on the credit facility that a wholly-owned subsidiary entered into in the second quarter of 2011.

In the third quarter of 2010, we issued $400 million of 5.75% senior unsecured notes and $300 million of 4.25% senior unsecured notes for net proceeds of approximately $394 million and $295 million, respectively.  The 5.75% notes mature on August 15, 2040 and the 4.25% notes mature on August 15, 2020.  We may redeem these notes at any time.

In the third quarter of 2010, we repurchased $126 million of 6.2% senior unsecured notes due March 15, 2016 and $100 million of 5.9% senior unsecured notes due March 15, 2014.  The net carrying amount of the debt repurchased was $234 million.  We recognized a pre-tax loss of $30 million upon early redemption of these notes.

Second Quarter

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 $627 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 five years from the date of the first advance.

First Quarter

In the first quarter of 2010, Corning repaid $58 million of debt, which included the redemption of $48 million principal amount of our 6.25% notes due February 18, 2010.

5.      Income Taxes

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

	Three months ended September 30,				Nine months ended September 30,
	2011		2010		2011		2010
Provision for income taxes	$	(110)	$	(14)	$	(347)	$	(142)
Effective tax rate		11.9%		1.8%		13.0%		5.3%

For the three and nine months ended September 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/(losses) of consolidated foreign companies;

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions; and

·   The impact of discrete items, including a $22 million non-taxable reduction to a contingent liability associated with an acquisition recorded in the first quarter of 2011 and a $41 million tax benefit from amending our 2006 U.S. Federal return to claim foreign tax credits.  Discrete items decreased our effective tax rate by 4.1 and 1.4 percentage points for the three and nine months ended September 30, 2011, respectively.

For the three months ended September 30, 2010, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

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

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions;

·   The benefit of excess foreign tax credits from repatriation of current year earnings of certain foreign subsidiaries; and

·   The impact of discrete items, including a $30 million loss from early redemption of debt.  Refer to Note 4 (Debt) for additional information about Corning’s debt redemption loss.  Discrete items decreased our effective tax rate by 0.6 percentage points.

In addition to the items noted above, the tax provision for the nine months ended September 30, 2010 reflected the impact of discrete items, including a $56 million charge from the reversal of the deferred tax asset associated with a subsidy for certain retiree medical benefits.  Discrete items in the nine months ended September 30, 2010 increased our effective tax rate by 2.5 percentage points.

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 2.3 and 2.8 percentage points for the three months ended September 30, 2011 and 2010, respectively.  The impact of the tax holidays on our effective tax rate is a reduction in the rate of 1.7 and 3.2 percentage points for the nine months ended September 30, 2011 and 2010, respectively.

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.

Under U.S. GAAP, a deferred tax liability should be recorded for any book basis greater than tax basis in a foreign subsidiary attributable to unremitted book earnings under the presumption that such earnings will ultimately be distributed and that such distribution would be subject to additional tax at the parent company level.  However, such presumption is rebuttable and no tax would be accrued to the extent the temporary difference is not expected to reverse in the foreseeable future because the unremitted foreign earnings are expected to be reinvested indefinitely.

-11-

As required by U.S. GAAP, Corning completes an annual detailed analysis to determine the extent to which its foreign unremitted earnings are indefinitely reinvested considering various factors including the following:

·   U.S. cash needs and liquidity;

·   International working capital, debt service and capital expansion needs;

·   Local regulatory, statutory or other legally enforceable restrictions on the distribution of foreign subsidiary and affiliate earnings;

·   Foreign joint venture agreement limitations on distributions; and

·   The current and/or future tax costs associated with repatriation, including potential legislative changes that could impact such costs.

Quarterly, Corning updates its analysis for material changes.

In the quarter ended March 31, 2010, Corning included in the computation of its estimated annual effective tax rate a tax benefit of $265 million related to an expected fourth quarter repatriation of $1.1 billion of 2010 foreign earnings.  The repatriated earnings represented a portion of the current year earnings of certain foreign subsidiaries and affiliates located in Asia and thus were not previously permanently reinvested.

There were two factors influencing Corning’s decision to consider repatriating these 2010 earnings.  One was Corning’s decision, as announced early in 2010, to pursue acquisitions that were expected to require cash to be available in the U.S. in excess of amounts expected to be generated from domestic sources.  The second factor was proposed federal tax legislation which, if enacted, could significantly increase the tax cost of repatriation after 2010.  Because there had been no change in our longer term international capital expansion plans as of the first quarter, our intent to indefinitely reinvest foreign earnings accumulated through the year ended December 31, 2009 was not changed by these factors.

As of the year ended December 31, 2010, Corning had $8.9 billion of foreign unremitted earnings that it intends to keep indefinitely reinvested.  It is not practical to calculate the unrecognized deferred tax liability on those earnings with reasonable accuracy.

Of this amount, nearly 70% consists of:

·   Non-liquid operating assets or short term liquidity required to meet current international working capital needs; and

·   SCP or other joint venture unremitted earnings that require a joint determination with our partners to remove any indefinitely reinvested representation.

Additionally, in the third quarter of 2010, Corning announced a significant multi-year investment plan that was expected to result in 2011 capital investment of $2.4 billion to $2.7 billion, the substantial majority of which would be spent internationally and would include over the term of the plan: $800 million for additional LCD capacity in China; capacity expansion for Eagle XG LCD glass and CorningÒ GorillaÒ Glass in Asia; expansion of automotive substrate facilities in China and Germany; and a new manufacturing and distribution center in China for our Life Sciences businesses.  These factors in addition to the fact that Corning has sufficient access to funds in the U.S. to fund currently anticipated domestic needs result in our ability and intent to indefinitely reinvest our foreign unremitted earnings of $8.9 billion as of December 31, 2010.

In April 2011, Korean tax authorities completed a tax audit of Samsung Corning Precision.  As a result, the tax authorities issued a pre-assessment of approximately $45 million for an asserted underpayment of withholding tax on dividends paid from September 2006 through March 2009.  Our first level of appeal was denied on October 5, 2011 and a formal assessment was issued.  The assessment will be paid in full by the end of 2011, which will allow us to continue the appeal process.  Samsung Corning Precision and Corning believe we will maintain our position when all available appeal remedies have been exhausted.

Additionally, the Korean Board of Audit and Inspection (the “BOAI”) has recently initiated a review of tax exemptions previously granted to Samsung Corning Precision by the National Tax Service.  The BOAI has the authority to reverse part or all of the tax exemption granted, at which time the decision may be appealed.  We believe that SCP should sustain its entire tax exemption.  SCP is unable to make a reasonable estimate of additional tax that could potentially result from the BOAI review.

On December 31, 2007, Samsung Corning Precision acquired all of the outstanding shares of Samsung Corning Co., Ltd. (Samsung Corning).  After the transaction, Corning retained its 50% interest in Samsung Corning Precision.  Prior to their merger, Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) and Samsung Corning Co. Ltd. (Samsung Corning) were two of approximately thirty co-defendants in a lawsuit filed by Seoul Guarantee Insurance Co. and thirteen other creditors (SGI and Creditors) for alleged breach of an agreement that approximately twenty-eight affiliates of the Samsung group (Samsung Affiliates) entered into with SGI and Creditors on August 24, 1999 (the Agreement).  The lawsuit is pending in the courts of South Korea.  Under the Agreement, it is alleged that the Samsung Affiliates agreed to sell certain shares of Samsung Life Insurance Co., Ltd. (SLI), which had been transferred to SGI and Creditors in connection with the petition for court receivership of Samsung Motors Inc.  In the lawsuit, SGI and Creditors allege a breach of the Agreement by the Samsung Affiliates and are seeking the loss of principal (approximately $1.95 billion) for loans extended to Samsung Motors Inc., default interest and a separate amount for breach.  On January 31, 2008, the Seoul District Court ordered the Samsung Affiliates: to pay approximately $1.3 billion by disposing of 2,334,045 shares of SLI less 1,165,955 shares of SLI previously sold by SGI and Creditors and paying the proceeds to SGI and Creditors; to satisfy any shortfall by participating in the purchase of equity or subordinate debentures issued by them; and pay default interest of 6% per annum.  The ruling was appealed.  On November 10, 2009, the Appellate Court directed the parties to attempt to resolve this matter through mediation.  On January 11, 2011, the Appellate Court ordered the Samsung Affiliates to pay 600 billion won in principal and 20 billion won in delayed interest to SGI and Creditors.  Samsung promptly paid those amounts, which approximated $550 million when translated to United States Dollars, from a portion of an escrow account established upon completion of SLI’s initial public offering (“IPO”) on May 7, 2010.  On February 7, 2011, the Samsung Affiliates appealed the Appellate Court’s ruling to the Supreme Court of Korea and the appeal is currently in progress.  Samsung Corning Precision has not contributed to any payment related to these disputes, and has concluded that no provision for loss should be reflected in its financial statements.  Other than as described above, no claim in these matters has been asserted against Corning or any of its affiliates.

In connection with an investigation by the Commission of the European Communities, Competition DG, of alleged anticompetitive behavior relating to the worldwide production of LCD glass, Corning and Samsung Corning Precision received requests for information from the Competition DG on March 30, 2009 and October 9, 2009.  Each party has responded to these requests.  Samsung Corning Precision has also responded to the Competition DG and authorities in other jurisdictions, including the United States, in connection with similar investigations of alleged anticompetitive behavior relating to worldwide production of cathode ray tube glass.  On October 7, 2011, Samsung Corning Precision was informed by the Antitrust Division of the U.S. Department of Justice (“DOJ”) that the DOJ had closed its investigation of cathode ray tube glass.  On October 19, 2011, the European Commission announced that it had settled its cartel investigation of cathode ray tube glass.  Samsung Corning Precision received full immunity, and no fines were imposed on it, because of its early cooperation in the Commission’s investigation.  The Commission fined three other makers of cathode ray tube glass.

In September 2009, Corning and Samsung Corning Precision formed Corsam Technologies LLC (Corsam), a new equity affiliate established to provide glass technology research for future product applications.  Samsung Corning Precision invested $124 million in cash and Corning contributed intellectual property with a corresponding value.  Corning and Samsung Corning Precision each own 50% of the common stock of Corsam and Corning has agreed to provide research and development services at arms length to Corsam.  Corning does not control Corsam because Samsung Corning Precision’s other investors maintain significant participating voting rights.  In addition, Corsam has sufficient equity to finance its activities, the voting rights of investors in Corsam are considered substantive, and the risks and rewards of Corsam’s research are shared only by those investors noted.  As a result, Corsam is accounted for under the equity method of accounting for investments.

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 September 30,				Nine months ended September 30,
	2011		2010		2011		2010
Statement of Operations:
Net sales	$	1,661	$	1,515	$	4,908	$	4,413

Related Party Transactions:

Dividends received from Dow Corning	$	65	$	56	$	245	$	167

Amounts owed to Dow Corning totaled $2 million as of September 30, 2011.  At December 31, 2010, amounts owed to Dow Corning were not significant.

At September 30, 2011, Dow Corning’s marketable securities included approximately $255 million of auction rate securities, net of a temporary impairment of $36 million.  As a result of the temporary impairment, unrealized losses of $30 million, net of $6 million for a minority interest’s share, were included in accumulated other comprehensive income in Dow Corning’s consolidated balance sheet.  Corning’s share of this unrealized loss was $15 million and is included in Corning’s accumulated other comprehensive income.

In February 2011, Dow Corning amended and restated its revolving credit agreement to provide $1 billion senior, unsecured revolving line of credit through February 2016.  Dow Corning believes it has adequate liquidity to fund operations, its capital expenditure plans, breast implant settlement liabilities, and shareholder dividends.

In 1995, Corning fully impaired its investment in Dow Corning after it filed for bankruptcy protection.  Corning did not recognize net equity earnings from the second quarter of 1995 through the end of 2002.  Corning began recognizing equity earnings in the first quarter of 2003 when management concluded that Dow Corning’s emergence from bankruptcy was probable.  Corning considers the $249 million difference between the carrying value of its investment in Dow Corning and its 50% share of Dow Corning’s equity to be permanent.

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.  The Plan also includes releases for Corning and Dow Chemical as shareholders in exchange for contributions to the Plan.

-18-

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 September 30, 2011, 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 September 30, 2011, Dow Corning has estimated the liability to commercial creditors to be within the range of $84 million to $277 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 $84 million, net of applicable tax benefits.  In addition, the London Market Insurers (the LMI Claimants) claimed a reimbursement right with respect to a portion of insurance proceeds previously paid by the LMI Claimants to Dow Corning.  This claim was based on a theory that the LMI Claimants overestimated Dow Corning’s liability for the resolution of implant claims pursuant to the Plan.  Based on settlement negotiations, Dow Corning had estimated that the most likely outcome would result in payment to the LMI Claimants in a range of $10 million to $20 million.  As of September 30, 2011, Dow Corning and the LMI Claimants have settled the claim for an amount within that range.  There are a number of other claims in the bankruptcy proceedings against Dow Corning awaiting resolution by the U.S. District Court, and it is reasonably possible that Dow Corning may record bankruptcy-related charges in the future.  The remaining tort claims against Corning are expected to be channeled by the Plan into facilities established by the Plan or otherwise defended by the Litigation Facility.

Hemlock Semiconductor Corporation, of which Dow Corning owns 63%, brought an action against one of its customers to enforce supply agreements requiring the customer to purchase or pay for large quantities of polycrystalline silicon used in the solar power industry.  The customer had previously announced its decision to exit the solar power business and denied its liability to purchase further products under existing supply agreements.

Pittsburgh Corning Corporation (PCC)

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.  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 settlement for asbestos litigation.  At September 30, 2011 and December 31, 2010, the fair value of PCE significantly exceeded its carrying value of $137 million and $129 million, respectively.  There have been no impairment indicators for our investment in PCE and we continue to recognize equity earnings of this affiliate.  PCC filed for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Western District of Pennsylvania on April 16, 2000.  At that time, Corning determined that it lacked the ability to recover the carrying amount of its investment in PCC and its investment was other-than-temporarily impaired.  As a result, we reduced our investment in PCC to zero.  Refer to Note 3 (Commitments and Contingencies) for additional information about PCC and PCE.

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 four variable interest entities that are not considered significant to Corning’s consolidated financial statements.  Corning does not have retained interests in assets transferred to an unconsolidated entity that serve as credit, liquidity or market risk support to that entity.

Amortization expense related to these intangible assets is estimated to be $14 million for 2011 and $16 million thereafter.

12.      Customer Deposits

In 2005 and 2004, several of Corning’s customers entered into long-term purchase and supply agreements in which Corning’s Display Technologies segment would supply large-size glass substrates to these customers over periods of up to six years.  As part of the agreements, these customers agreed to advance cash deposits to Corning for a portion of the contracted glass to be purchased.  Between 2004 and 2007, we received a total of $937 million for customer deposit agreements.  We do not expect to receive additional deposits related to these agreements.

Upon receipt of the cash deposits made by customers, we recorded a customer deposit liability.  This liability is reduced at the time of future product sales over the life of the agreements.  As product is shipped to a customer, Corning recognizes revenue at the selling price and issues credit memoranda for an agreed amount of the customer deposit liability.  The credit memoranda are applied against customer receivables resulting from the sale of product, thus reducing operating cash flows in later periods as these credits are applied to cash deposits received in earlier periods.

During the three and nine months ended September 30, 2011, we issued $7 million and $21 million, respectively, in credit memoranda.  During the three and nine months ended September 30, 2010, we issued $8 million and $76 million, respectively, in credit memoranda.  Customer deposit liabilities were $7 million and $27 million at September 30, 2011 and December 31, 2010, respectively, which are recorded in the current portion of other accrued liabilities in our consolidated balance sheets.  Because these liabilities are denominated in Japanese yen, changes in the balances include the impact of movements in the Japanese yen-U.S. dollar exchange rate.

In the event customers do not purchase the agreed upon quantities of product, subject to specific conditions outlined in the agreements, Corning may retain certain amounts of the customer deposits.  If Corning does not deliver agreed upon product quantities, subject to specific conditions outlined in the agreements, Corning may be required to return certain amounts of customer deposits.

13.      Employee Retirement Plans

The following table summarizes the components of net periodic benefit cost for Corning’s defined benefit pension and postretirement health care and life insurance plans (in millions):

	Pension benefits								Postretirement benefits
	Three months ended September 30,				Nine months ended September 30,				Three months ended September 30,				Nine months ended September 30,
	2011		2010		2011		2010		2011		2010		2011		2010
Service cost	$	13	$	11	$	40	$	34	$	3	$	2	$	11	$	9

Total pension and postretirement benefit expense	$	33	$	22	$	97	$	68	$	18	$	17	$	56	$	54

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.  In response to rising health care costs, we changed our cost-sharing approach for retiree medical coverage.  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.  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.

14.      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 exposure 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 counterparty default.  Neither we nor our counterparties are required to post collateral for these financial instruments.

The amount of hedge ineffectiveness at September 30, 2011 and at December 31, 2010 was insignificant.

-22-

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.  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 September 30, 2011, the amount of net losses expected to be reclassified into earnings within the next 12 months is $24 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.

Net Investment in Foreign Operations

In February 2000, we issued $500 million of Euro-denominated notes that were designated as a hedge of a net investment in foreign operations.  The effective portion of the changes in fair value of the outstanding debt balance has been included as a component of the foreign currency translation adjustment (CTA) within accumulated other comprehensive income (loss).  In February 2010, we repaid the remaining $48 million balance of this debt.  At that time, the cumulative amount of CTA related to this debt was a net loss of $140 million, which will remain in accumulated other comprehensive income until ultimate disposition of the underlying Euro investment.

The following tables summarize the notional amounts and respective fair values of Corning’s derivative financial instruments for September 30, 2011 and December 31, 2010 (in millions):

15.      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 September 30, 2011 and December 31, 2010, the Company did not have any financial assets or liabilities that were measured using unobservable (or Level 3) inputs.

-25-

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
	September 30,  2011	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 (2)	$  170		$170
Non-current liabilities:
Other liabilities (2)	$    25		$  25

(1) Short-term investments are measured using observable quoted prices for similar assets.

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

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

16.      Share-based Compensation

Stock Compensation Plans

The Company measures and recognizes compensation cost for all share-based payment awards made to employees and directors, including grants of employee stock options and employee stock purchases related to the Worldwide Employee Share Purchase Plan (WESPP), based on estimated fair values.  Fair values for stock options granted prior to January 1, 2010 were estimated using a lattice-based binomial valuation model.  In 2010, Corning began estimating fair values for stock options granted using a multiple-point Black-Scholes model.  Both models incorporate the required assumptions and meet the fair value measurement objective under U.S. GAAP.

-26-

Share-based compensation cost was approximately $21 million and $22 million for the three months ended September 30, 2011 and 2010, respectively, and approximately $66 million and $77 million for the nine months ended September 30, 2011 and 2010, 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.  On February 3, 2010, Corning’s Board of Directors approved the recommendation to terminate on-going WESPP contributions effective March 31, 2010.  Compensation expense for the WESPP is included in periods ended prior to April 1, 2010.

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 nine months ended September 30, 2011:

	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, 2010	72,461	$16.22
Granted	5,288	21.15
Exercised	(7,228)	11.49
Forfeited and Expired	(4,255)	36.79
Options Outstanding as of September 30, 2011	66,266	15.81	4.95	114,629
Options Exercisable as of September 30, 2011	52,372	15.52	4.09	102,861

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 September 30, 2011, which would have been received by the option holders had all option holders exercised their options as of that date.

As of September 30, 2011, there was approximately $36 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 2 years.  Compensation cost related to stock options was approximately $37 million and $41 million for the nine months ended September 30, 2011 and 2010, respectively, and approximately $12 million for the three months ended September 30, 2011 and 2010.

Proceeds received from the exercise of stock options were $82 million and $39 million for the nine months ended September 30, 2011 and 2010, respectively, and $9 million and $10 million for the three months ended September 30, 2011 and 2010, 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 nine months ended September 30, 2011 and 2010 was approximately $71 million and $41 million, respectively, and $3 million and $9 million for the three months ended September 30, 2011 and 2010, 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 5 (Income Taxes) to the consolidated financial statements.

Corning used a binomial lattice model to estimate the fair values of stock option grants through December 31, 2009.  Effective January 1, 2010, Corning began using a multiple-point Black-Scholes model to estimate the fair value of stock option grants.  The financial impact of the change in valuation models is insignificant.

-27-

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

	Three months ended September 30,		Nine months ended September 30,
	2011	2010	2011	2010
Expected volatility	48-49%	49%	47-49%	48-49%
Weighted-average volatility	48%	49%	47-48%	49%
Expected dividends	1.05%	1.15%	1.10%	1.15-1.40%
Risk-free rate	1.0-1.5%	1.5-1.9%	1.0-2.7%	1.5-3.2%
Average risk-free rate	1.5%	1.9%	1.5-2.6%	1.9-3.2%
Expected term (in years)	5.1-6.7	5.1-6.5	5.1-6.7	5.1-6.5
Pre-vesting departure rate	0.4-3.9%	1.4-3.6%	0.4-3.9%	1.4-3.6%

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 separate 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, 2010, and changes during the nine months ended September 30, 2011:

	Shares (000’s)	Weighted Average Grant-Date Fair Value
Non-vested shares at December 31, 2010	3,698	$18.33
Granted	1,466	19.44
Vested	(535)	21.31
Forfeited	(272)	23.03
Non-vested shares at September 30, 2011	4,357	$18.04

-28-

As of September 30, 2011, there was approximately $30 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 2 years.  Compensation cost related to time-based restricted stock and restricted stock units was approximately $23 million and $22 million for the nine months ended September 30, 2011 and 2010, respectively, and $7 million for the three months ended September 30, 2011 and 2010.

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, 2010, and changes during the nine months ended September 30, 2011:

	Shares (000’s)	Weighted- Average Grant-Date Fair Value
Non-vested restricted stock and restricted stock units at December 31, 2010	6,072	$ 9.24
Granted
Vested	(637)	14.09
Forfeited and cancelled	(226)	8.67
Non-vested restricted stock and restricted stock units at September 30, 2011	5,209	$ 8.67

As of September 30, 2011, there was approximately $4 million of unrecognized compensation cost related to non-vested performance-based restricted stock and restricted stock units compensation arrangements granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 0.3 year.  Compensation cost related to performance-based restricted stock and restricted stock units was approximately $6 million and $12 million for the nine months ended September 30, 2011 and 2010, respectively, and $2 million and $3 million for the three months ended September 30, 2011 and 2010, respectively.

Worldwide Employee Stock Purchase Plan

In addition to the Stock Option Plans and Incentive Stock Plans, Corning offered a Worldwide Employee Share Purchase Plan (WESPP).  Under the WESPP, substantially all employees could elect to have up to 10% of their annual wages withheld to purchase our common stock.  The purchase price of the stock was 85% of the end-of-quarter closing market price.  Compensation cost related to the WESPP for all periods presented is immaterial.

On February 3, 2010, Corning’s Board of Directors approved the recommendation to terminate on-going WESPP contributions effective March 31, 2010 and the WESPP terminated in May 2010.

18.      Significant Customers

For the three months ended September 30, 2011, Corning’s sales to Sharp Electronics Corporation, a customer of the Display Technologies segment, were greater than 10% of the Company’s consolidated net sales.  For the three months ended September 30, 2010, Corning’s sales to each of the following two customers of the Display Technologies segment were equal to or greater than 10% of the Company’s consolidated net sales: AU Optronics Corporation (AUO), and Sharp Electronics Corporation.

For the nine months ended September 30, 2011, there were no customers that were equal to or greater than 10% of the Company’s consolidated net sales.  For the nine months ended September 30, 2010, Corning’s sales to each of the following three customers of the Display Technologies segment were equal to or greater than 10% of the Company’s consolidated net sales:  AUO, Chimei Innolux Corporation, and Sharp Electronics Corporation.

19.      Operating Segments

Our reportable operating 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 operating 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.

-30-

All other operating 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 operating 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) 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.  In the nine months ended September 30, 2010 equity earnings of affiliated companies, net of impairments, includes a credit of $21 million for our share of U.S. advanced energy manufacturing tax credits at Dow Corning Corporation.

(3) In the three and nine months ended September 30, 2011, Corning recorded a charge of $5 million and $15 million, respectively, to adjust the asbestos liability for the change in value of the components of the Amended PCC Plan.  In the three and nine months ended September 30, 2010, Corning recorded a charge of $6 million and a net credit of $41 million, respectively, primarily reflecting the change in the terms of the proposed asbestos settlement.

(4) In the three months ended September 30, 2011, Corning recorded a $41 million tax benefit from the filing of an amended 2006 U.S. Federal Tax return to claim foreign tax credits.  In the three months ended September 30, 2010, Corning recorded a loss of $30 million ($19 million after-tax) from the repurchase of $126 million principal amount of our 6.2% senior unsecured notes due March 15, 2016 and $100 million principal amount of our 5.9% senior unsecured notes due March 15, 2014.  In the nine months ended September 30, 2010, other corporate items included a tax charge of $56 million from the reversal of the deferred tax asset associated with a Medicare subsidy.

In the Display Technologies operating segment, assets increased from $9.1 billion at December 31, 2010 to $10.3 billion at September 30, 2011.  The increase is due primarily to an increase in investments due to earnings from Samsung Corning Precision and capital expenditures of approximately $800 million, offset somewhat by the reallocation of certain assets to the Specialty Materials segment.  In the Telecommunications operating segment, assets increased from $1.0 billion at December 31, 2010 to $1.2 billion at September 30, 2011.  The increase is due primarily to increases of certain working capital balances, the result of a small acquisition completed in the first quarter of 2011 and capital expenditures of approximately $100 million.  In the Specialty Materials operating segment, assets increased from $900 million at December 31, 2010 to $1.6 billion at September 30, 2011.  The increase is due primarily to the reallocation of certain assets from the Display Technologies operating segment and capital expenditures of approximately $300 million.

The sales of each of our reportable operating segments are concentrated across a relatively small number of customers.  In the third quarter of 2011, 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, four customers accounted for 76% of total segment sales.

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

·   In the Environmental Technologies segment, three customers accounted for 89% of total segment sales.

·   In the Specialty Materials segment, two customers accounted for 47% of total segment sales.

·   In the Life Sciences segment, two customers accounted for 51% of total segment sales.

-32-

In the nine months ended September 2011, 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, three customers accounted for 67% of total segment sales.

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

·   In the Environmental Technologies segment, three customers accounted for 85% of total segment sales.

·   In the Specialty Materials segment, two customers accounted for 40% of total segment sales.

·   In the Life Sciences segment, two customers accounted for 43% 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 use 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

·   Operating Segments

·   Liquidity and Capital Resources

·   Critical Accounting Estimates

·   New Accounting Standards

·   Environment

·   Forward-Looking Statements

OVERVIEW

Strong business performance in all of our operating segments led to an increase in Corning’s net sales in the three and nine months ended September 30, 2011, when compared to the same periods last year.  Robust retail demand for portable display devices that utilize our CorningÒ GorillaÒ glass resulted in significantly higher sales in our Specialty Materials segment.  The increase in sales in our Display Technologies segment was due to stronger demand by our customers in the third quarter of 2011, when compared to a relatively weak third quarter in 2010.  Improved sales in our Environmental Technologies reflected increased demand worldwide for automotive and diesel products.  Sales in our Telecommunications segment were also higher, driven by strength in demand for our fiber-to-the-premises, optical fiber and cable, and enterprise networks products.

In the third quarter of 2011, we generated net income of $811 million or $0.51 per share, compared to net income of $785 million or $0.50 per share for the same period in 2010.  When compared to the same period last year, the increase in net income in the third quarter of 2011 was due largely to the following items:

·   Higher net income in the Specialty Materials, Telecommunications, and Environmental Technologies segments;

·   A decrease in operating expenses due to a $22 million reduction in a contingent liability associated with an acquisition recorded in the first quarter of 2011 and lower performance-based compensation costs;

·   A tax benefit from amending our 2006 U.S. Federal tax return to claim foreign tax credits in the amount of $41 million;

·   The absence of the loss on retirement of debt in the amount of $30 million, incurred in the third quarter of 2010; and

·   The positive impact from movements in foreign exchange rates in the amount of $91 million.

The increase in net income was offset somewhat by the following items:

·   A decline in equity earnings from Samsung Corning Precision, our equity affiliate located in Korea, due to lower volume and price declines;

·   A decline in equity earnings from Dow Corning, primarily due to an increase in raw materials costs, higher interest expense, and a sales shift from higher priced, higher margin silicones to lower priced, lower margin silicones;

·   Lower royalty income from Samsung Corning Precision resulting from lower sales volume;

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

o   The absence of the favorable tax impact from the decision to repatriate earnings from certain foreign subsidiaries in 2010; and

o   The expiration of tax holidays in Taiwan.

-34-

In the nine months ended September 30, 2011, we reported net income of $2.3 billion or $1.46 per share compared to net income of $2.5 billion or $1.59 per share for the same period last year.  Results were driven by the same favorable dynamics seen in the third quarter, but were more than offset by significantly lower equity earnings from Samsung Corning Precision and Dow Corning, higher taxes and the absence of favorable events that occurred in 2010.  In the first nine months of 2010, we recorded a decrease to asbestos settlement liability in the amount of $41 million, compared with a charge of $15 million for the same period this year.  Also, in the first quarter of 2010, we recorded a credit of $21 million for our share of U.S. advanced energy manufacturing tax credits at Dow Corning Corporation.

Net income in the nine months ended September 30, 2011 was favorably impacted by $216 million from movements in foreign exchange rates, when compared to the same period for 2010.

Our key priorities for 2011 remain similar to those from previous years:  protect our financial health and invest in the future.  During the third quarter of 2011, 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:

·   Our debt to capital ratio of 10% at September 30, 2011 is down from 11% reported at December 31, 2010.

·   Operating cash flow in the nine months ended September 30, 2011 was $2.0 billion.

·   We ended the third quarter of 2011 with $6.4 billion of cash, cash equivalents and short-term investments, consistent with the balance at December 31, 2010, and well above our debt balance of $2.3 billion.

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 third quarter of 2011 when compared to the same period last year, as we remain committed to investing in research, development, and engineering to drive innovation.  For the nine months ended September 30, 2011, research, development, and engineering spending increased when compared to the same period last year, but was down slightly as a percentage of sales.

In 2011, 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 longer range opportunities in each of our market segments

We continue to work on technologies for glass substrates for active matrix LCDs, diesel filters and substrates in response to tightening emissions control standards, and the optical fiber and cable, and hardware and equipment that enable fiber-to-the-premises, optical cable systems for next generation data centers and wireless solutions for diverse venue applications such as distributed antenna systems, fiber to the tower and antennas.  In addition, we have increased our research, development, and engineering spending to support the advancement of new product attributes for our CorningÒ GorillaÒ glass suite of products.  We will continue to focus on adjacent glass opportunities, including products such as glass substrates for thin-film photovoltaics in solar applications, which leverage existing materials or manufacturing processes with modifications.

Capital spending totaled $1.7 billion and $534 million for the nine months ended September 30, 2011 and 2010, respectively.  Spending increased in the first half of 2011, largely as a result of several multi-year investment plans announced in 2010 that will increase manufacturing capacity in several of our operating segments.  Specifically, the increase in spending in the first nine months of 2011 was driven by construction costs for an LCD glass substrate facility in China for our Display Technologies segment and a capacity expansion project for Specialty Materials’ CorningÒ GorillaÒ glass in Japan.  We expect our 2011 capital spending to be approximately $2.4 billion.  Approximately $1.3 billion will be directed toward our Display Technologies segment.  Our 2012 capital spending program is expected to be approximately $1.8 billion.

-35-

Corporate Outlook

Corning expects significant sales growth in 2011, led by strong sales growth of our CorningÒ GorillaÒ glass products.  We expect the worldwide LCD glass market demand to be approximately 3.2 billion square feet versus our previous expectation of 3.3 billion to 3.4 billion square feet.  This is up from 3.15 billion square feet in 2010.  Earnings will be negatively impacted by higher taxes due to the absence of the 2010 tax benefits resulting from our cash repatriation actions, increased income in higher tax rate jurisdictions and tax holiday expirations.  We expect equity earnings to be lower.  Samsung Corning Precision will be impacted by lower volume, price declines and higher taxes in 2011.  Equity earnings from Dow Corning will be lower due to a combination of higher raw material costs and softer demand in the worldwide silicone market, resulting in significant price declines.  Cash flow from operations may decline when compared to last year, as we expect lower dividends from equity affiliates.  We will also use more cash for investing activities as we expand our capacity to meet growing demand.  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 nine months ended September 30, 2011, net sales increased in all of our segments when compared to the same periods in 2010.  The increase in net sales in the three and nine months ended September 30, 2011 was due to the significant increase in sales in our Specialty Materials segment, up 88% and 119%, respectively.  Additionally, sales in the Telecommunications and Environmental Technologies segments also increased considerably when compared to the same periods last year.  For the three and nine months ended September 30, 2011, net sales were favorably impacted by approximately $100 million and $293 million, respectively, from movements in foreign exchange rates.

-37-

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.

Gross Margin

As a percentage of net sales, gross margin for the three months ended September 30, 2011 increased when compared to the same period last year, due primarily to improvements in the Specialty Materials and Environmental Technologies segments.

As a percentage of net sales, gross margin for the nine months ended September 30, 2011 decreased when compared to the same period last year, due to price declines in the Display Technologies segment.

Selling, General, and Administrative Expenses

For the three months ended September 30, 2011, selling, general, and administrative expenses decreased by $34 million when compared to the same period last year, due to an adjustment to performance-based compensation and a credit resulting from a reduction in a contingent liability associated with an acquisition recorded in the first quarter of 2011.  As a percentage of net sales, these expenses for the end of the third quarter of 2011 were down when compared to the same period last year.

For the nine months ended September 30, 2011, selling, general, and administrative expenses increased by $19 million when compared to the same period last year, due to an increase in salaries, partially as a result of two small acquisitions completed within the past 12 months, offset by an adjustment to performance-based compensation costs and a credit resulting from a reduction in a contingent liability associated with an acquisition recorded in the first quarter of 2011.  As a percentage of net sales, these expenses for the end of the third quarter of 2011 were down slightly 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 nine months ended September 30, 2011, research, development, and engineering expenses increased by $18 million and $57 million, respectively, when compared to the same periods last year.  As a percentage of net sales, research, development, and engineering expenses for the three and nine months ended September 30, 2011, were slightly lower when compared to the same periods in 2010, primarily due to the increase in net sales.

Corning’s research, development, and engineering expenses are currently focused on baseline research for new business development, as well as on our Display Technologies, Environmental Technologies, Telecommunications, and Specialty Materials segments, as we strive to capitalize on growth opportunities in those segments.

Asbestos Litigation

In the three months ended September 30, 2011 and 2010, we recorded an increase to our asbestos settlement liability of $5 million and $6 million, respectively.  In the nine months ended September 30, 2011, we recorded a $15 million increase to our asbestos settlement liability, compared to a decrease of $41 million for the same period last year.  The net decrease in the asbestos settlement liability in the first half of 2010 was due to a change in the terms of the proposed settlement that reduced the amount of cash expected to be contributed to the settlement.  For additional information on this matter, refer to Note 3 (Commitments and Contingencies) to the consolidated financial statements and Part II – Other Information, Item 1. Legal Proceedings.

Equity in Earnings of Affiliated Companies

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

	Three months ended September 30,				Nine months ended September 30,
	2011		2010		2011		2010
Samsung Corning Precision	$	229	$	394	$	853	$	1,102
Dow Corning Corporation		89		97		275		320
All other		6		13		22		25
Total equity earnings	$	324	$	504	$	1,150	$	1,447

The decrease in equity earnings from Samsung Corning Precision for the three months ended September 30, 2011, when compared to the same period last year, was primarily due to the following:

·   Volume and price declines of 25% and 15%, respectively; and

·   Higher taxes due to the partial expiration of a Korean tax holiday.

The favorable impact from movements in foreign exchange rates in the amount of $34 million partially offset the decline.  Equity earnings for Samsung Corning Precision are explained more fully in the discussion of the performance of our Display Technologies segment.

The decrease in equity earnings from Dow Corning for the three months ended September 30, 2011, when compared to the same period last year, reflected the following:

·   A significant increase in raw materials costs;

·   A sales shift from higher priced, higher margin silicones to lower priced, lower margin silicones; and

·   An increase in interest expense.

The decrease in equity earnings from Dow Corning was partially offset by the following:

·   Higher volume in Dow Corning’s traditional silicone products and improved volume at Hemlock Semiconductor Corporation (Hemlock), Dow Corning’s consolidated subsidiary that makes high purity polycrystalline silicon for the semiconductor and solar industries;

·   Lower performance-based compensation expenses; and

·   The favorable impact from movements in foreign exchange rates.

In addition to the items described above, equity earnings for the nine months ended September 30, 2011, when compared to the same period last year, were also lower due to the absence of advanced energy manufacturing tax credits approved by the U.S. government for Dow Corning’s manufacturing expansion projects that support the solar industry.  Corning’s share of these credits was $21 million in the first quarter of 2010.

Corning’s equity earnings for the three and nine months ended September 30, 2011 were favorably impacted by $33 million and $102 million, respectively, from movements in foreign exchange rates when compared to the same periods last year.

In the fourth quarter of 2011, we expect equity earnings to decrease by approximately 5% when compared to the third quarter of 2011, driven by a decrease of approximately 40% in equity earnings at Dow Corning, offset somewhat by higher equity earnings at Samsung Corning Precision.  We anticipate Dow Corning’s sales to be flat sequentially, but net income will be lower, due primarily to softening demand in the worldwide silicone market and the resulting price declines.  Dow Corning’s net income will also be impacted by the absence of the decrease in performance-based compensation expense seen in the third quarter of 2011.  We expect earnings at Hemlock to decline due to lower demand for solar products and significant price declines, driven by the reduction of solar incentives in Europe and large inventories of polycrystalline silicon in the marketplace.

Income Before Income Taxes

Income before income taxes for the three and nine months ended September 30, 2011, was positively impacted by $102 million and $236 million, respectively, due to movements in foreign exchange rates when compared to the same period 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 September 30,				Nine months ended September 30,
	2011		2010		2011		2010
Provision for income taxes	$	(110)	$	(14)	$	(347)	$	(142)
Effective tax rate		11.9%		1.8%		13.0%		5.3%

For the three and nine months ended September 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/(losses) of consolidated foreign companies;

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions; and

·   The impact of discrete items, including a $22 million non-taxable reduction in a contingent liability associated with an acquisition recorded in the first quarter of 2011 and a $41 million tax benefit from amending our 2006 U.S. Federal return to claim foreign tax credits.  Discrete items decreased our effective tax rate by 4.1 and 1.4 percentage points for the three and nine months ended September 30, 2011, respectively.

For the three months ended September 30, 2010, the effective income tax rate differed from the U.S. statutory rate of 35%, primarily due to the following items:

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

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions;

·   The benefit of excess foreign tax credits from repatriation of current year earnings of certain foreign subsidiaries; and

·   The impact of discrete items, including a $30 million loss from early redemption of debt.  Refer to Note 4 (Debt) for additional information about Corning’s debt redemption loss.  Discrete items decreased our effective tax rate by 0.6 percentage points.

In addition to the items noted above, the tax provision for the nine months ended September 30, 2010 reflected the impact of discrete items, including a $56 million charge from the reversal of the deferred tax asset associated with a subsidy for certain retiree medical benefits.  Discrete items in the nine months ended September 30, 2010 increased our effective tax rate by 2.5 percentage points.

Refer to Note 5 (Income Taxes) to the consolidated financial statements for additional information.

·   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 operating 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 operating 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 operating 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 increase in net sales for the third quarter of 2011, compared to the same period last year, reflected an increase in volume of 34% and the favorable impact of $79 million from movements in foreign exchange rates, offset by price declines of 15%.  The increase in volume was primarily due to the absence of the large supply chain correction by our base business customers seen in the third quarter of 2010.  Our base business customers experienced quarterly fluctuations in panel utilization rates in the first three quarters of 2010, which has not been repeated in 2011 to the extent seen in 2010.  Although the LCD industry has seen some supply chain contraction in the third quarter of 2011, the effect of this contraction has been felt disproportionately by Korean panel makers, which has affected the sales volume of our equity affiliate, Samsung Corning Precision.  Sequential volume in our base business through the first three quarters of 2011 has remained relatively consistent, as our base business customers react more cautiously than they did in 2010.

When compared to the same period last year, the increase in net sales for the nine months ended September 30, 2011 reflected an increase in volume of 10% and the favorable impact of $240 million from movements in foreign exchange rates, offset by price declines of 14%.

When compared to same period last year, the decrease in equity earnings from Samsung Corning Precision in the three and nine months ended September 30, 2011 reflected price declines of 15% and 14%, respectively, and a decrease in volume of 25% and 8%, respectively, driven by the supply chain contraction in Korea and some market share loss.  The decrease was offset somewhat in the three and nine months ended September 30, 2011, by the favorable impact of $34 million and $104 million, respectively, from movements in foreign exchange rates.  Additionally, equity earnings were negatively impacted by higher taxes due to the partial expiration of a Korean tax holiday.

Because Corning sells to panel makers and not to end market consumers, supply chain expansion and contraction for this industry is a key factor in Corning’s volume.  While end market demand continues to grow in all LCD applications, inventory levels within the LCD supply chain have not kept pace with this growth, and have, in fact, declined in absolute terms during 2011 when compared to 2010.  As a result, we expect low year over year growth in the 2011 glass market, impacting volume growth at both our base business and at Samsung Corning Precision.

When compared to the same periods last year, the decrease in net income in the Display Technologies segment in the three and nine months ended September 30, 2011 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 and improved manufacturing efficiency.  Net income in the three and nine months ended September 30, 2011 includes the favorable impact of $64 million and $193 million, respectively, from movements in foreign exchange rates when compared to the same periods last year.

A number of Corning's patents and know-how are licensed to Samsung Corning Precision, as well as to third parties, which generates royalty income.  Royalty income from Samsung Corning Precision decreased in the three and nine months ended September 30, 2011, when compared to the same periods last year, reflecting the decline in sales volume at Samsung Corning Precision.  The existing license agreement with Samsung Corning Precision expires in the fourth quarter of 2011 and the existing documents provide that, unless the parties agree otherwise, the applicable royalty rate would decrease by more than fifty percent in a renewal or extension of the license.

Refer to Note 9 (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 Japan and Taiwan.  For the three months ended September 30, 2011, four customers of the Display Technologies segment that individually accounted for more than 10% of segment net sales, accounted for approximately 76% of total segment sales when combined.  For the nine months ended September 30, 2011, three customers of the Display Technologies segment that individually accounted for more than 10% of segment net sales, accounted for approximately 67% 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.

-42-

Samsung Corning Precision’s sales are also concentrated across a small number of its customers.  For the three months ended September 30, 2011, sales to two LCD panel makers located in Korea accounted for 92% of Samsung Corning Precision sales.  For the nine months ended September 30, 2011, sales to two LCD panel makers located in Korea accounted for 93% of Samsung Corning Precision sales.

Outlook:

We expect the overall LCD glass market in 2011, measured in square feet of glass, will increase slightly when compared to 2010.  We believe that the long-term drivers of the LCD market will be LCD television growth, driven by increased demand in emerging regions and a faster replacement cycle, as well as continued growth in the personal computer market.

In the fourth quarter of 2011, we expect volume at our wholly-owned business to be even or slightly down when compared to the third quarter.  At Samsung Corning Precision, volume is expected to increase at least 20% in the fourth quarter of 2011, when compared to the third quarter, as Samsung Corning Precision regains market share and panel makers increase utilization rates.  At both our wholly-owned business and at Samsung Corning Precision, we expect price declines to be more significant in the fourth quarter of 2011, when compared to price declines seen in previous quarters.

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 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 September 30,				% change	Nine months ended September 30,				% change
	2011		2010		11 vs. 10	2011		2010		11 vs. 10
Net sales:
Optical fiber and cable	$	276	$	232	19%	$	789	$	649	22%
Hardware and equipment		284		232	22%		793		620	28%
Total net sales	$	560	$	464	21%	$	1,582	$	1,269	25%
Net income	$	82	$	41	100%	$	169	$	79	114%

In the three and nine months ended September 30, 2011, net sales of the Telecommunications segment increased when compared to the same periods last year due to higher sales in all of the segment’s product lines, led by fiber-to-the-premises, optical fiber and cable, and enterprise network products.  Sales of fiber-to-the-premises products increased in the three and nine months ended September 30, 2011 by approximately 33% and 38%, respectively, when compared to the same periods in the prior year, driven by initiatives in Canada, Europe and Australia.  Sales in the three and nine months ended September 30, 2011 also increased due to a small acquisition completed in the first quarter of 2011.  Net sales in the three and nine months ended September 30, 2011 includes the favorable impact of $8 million and $20 million, respectively, from movements in foreign exchange rates when compared to the same periods last year.

For the three and nine months ended September 30, 2011, the increase in net income reflects the sales increases described above, coupled with a credit in the amount of $22 million for the decrease in a contingent liability associated with a first quarter acquisition.  Net income in the three and nine months ended September, 30, 2011 includes the favorable impact of $2 million and $4 million, respectively, from movements in foreign exchange rates when compared to the same periods last year.

-43-

The Telecommunications segment has a concentrated customer base.  For the three and nine months ended September 30, 2011, one customer of the Telecommunications segment represented approximately 12% of total segment sales in both periods.

Outlook:

For the fourth quarter of 2011, we expect sales to decrease 10% to 15% when compared to the third quarter of 2011, due to project timing and normal seasonality in the industry.

Environmental Technologies

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

	Three months ended September 30,				% change	Nine months ended September 30,				% change
	2011		2010		11 vs. 10	2011		2010		11 vs. 10
Net sales:
Automotive	$	119	$	119	0%	$	363	$	345	5%
Diesel		128		89	44%		401		239	68%
Total net sales	$	247	$	208	19%	$	764	$	584	31%
Net income	$	32	$	11	191%	$	93	$	27	244%

When compared to the previous year, the increase in net sales of this segment for the three and nine months ended September 30, 2011, resulted primarily from higher sales of our diesel products.  Net sales of diesel products were significantly higher when compared to the same periods last year, driven by an increase in truck production in the United States, implementation of European governmental regulations on light duty diesel vehicles, and the first stages of the implementation of non-road vehicle regulations in the United States.  Sales of our automotive products also increased in the three and nine months ended September 30, 2011, when compared to the same periods in 2010, reflecting the continuing recovery of worldwide automotive production.  Net sales in the three and nine months ended September 30, 2011 includes the favorable impact of $5 million and $13 million, respectively, from movements in foreign exchange rates, when compared to the same periods last year.

When compared to the same periods in 2010, net income in the three and nine months ended September 30, 2011, was higher due to the increase in sales volumes described above, improved manufacturing performance and reduced air freight.  Movements in foreign exchange rates did not significantly impact the results of this operating segment.

The Environmental Technologies segment sells to a concentrated customer base of catalyzer and emission control systems manufacturers, who then sell to automotive and diesel engine manufacturers.  Although our sales are to the emission control systems 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 nine months ended September 30, 2011, three customers of the Environmental Technologies segment, which individually accounted for more than 10% of segment net sales, accounted for approximately 89% and 85%, respectively, 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 fourth quarter of 2011, we expect sales to decline between 5% and 10% when compared to the third quarter of 2011 due to typical seasonal slowdown.

Specialty Materials

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

	Three months ended September 30,				% change	Nine months ended September 30,				% change
	2011		2010		11 vs. 10	2011		2010		11 vs. 10

Net income (loss)	$	38	$	(5)	*	$	69	$	(29)	*

* The percentage change calculation is not meaningful.

Net sales for the three and nine months ended September 30, 2011 increased significantly in the Specialty Materials segment, driven by continued strong sales of CorningÒ GorillaÒ glass.  Sales of CorningÒ GorillaÒ glass have continued to increase due to a combination of strong retail demand for handheld display devices, tablets and notebook computers and increased usage of our glass on these devices.  Sales of the segment’s other products also increased in the three and nine months ended September 30, 2011, when compared to the same periods in 2010, led by semiconductor optics and aerospace and defense products.  Net sales in the three and nine months ended September 30, 2011 includes the favorable impact of $3 million and $10 million, respectively, from movements in foreign exchange rates when compared to the same periods last year.

The increase in net income for the three and nine months ended September 30, 2011 was driven by the increase in sales described above, combined with improvements in manufacturing efficiency and the impact of cost reductions.  Net income for the three and nine months ended September 30, 2011 includes the unfavorable impact of $3 million and $13 million, respectively, from movements in foreign exchange rates when compared to the same periods in 2010.

For the three and nine months ended September 30, 2011, two customers of the Specialty Materials segment, which individually accounted for more than 10% of segment net sales, accounted for 47% and 40%, respectively, of total segment sales when combined.

Outlook:

For the fourth quarter of 2011, while difficult to forecast given the lack of visibility in the supply chain, we expect sales to decline approximately 15% sequentially, with declines felt across all product lines, including CorningÒ GorillaÒ glass.

Life Sciences

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

	Three months ended September 30,				% change	Nine months ended September 30,				% change
	2011		2010		11 vs. 10	2011		2010		11 vs. 10
Net sales	$	153	$	125	22%	$	452	$	368	23%
Net income	$	21	$	13	62%	$	51	$	48	6%

Net sales for the three and nine months ended September 30, 2011 increased when compared to the same periods last year, due to an acquisition completed in the fourth quarter of 2010 and higher sales in the segment’s existing product lines.  For the three and nine months ended September 30, 2011, net sales were favorably impacted by approximately $4 million and $10 million, respectively, from movements in foreign exchange rates when compared to the same periods in 2010.

For the three and nine months ended September 30, 2011, the increase in net income was driven by the increase in sales described above, offset partially by higher raw materials costs and the impact of the integration of the acquisition completed in 2010.  Net income for the three and nine months ended September 30, 2011 includes the favorable impact of $2 million and $4 million, respectively, from movements in foreign exchange rates when compared to the same periods in 2010.

-45-

For the three and nine months ended September 30, 2011, two customers of the Life Sciences segment, which individually accounted for more than 10% of net sales, accounted for 51% and 43%, respectively, of net sales when combined.

Outlook:

For the fourth quarter of 2011, we expect net sales to be slightly lower when compared to the third quarter of 2011, due to normal industry seasonality.

All Other

All other operating 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 September 30,				% change	Nine months ended September 30,				% change
	2011		2010		11 vs. 10	2011		2010		11 vs. 10
Net sales	$	1	$	1	0%	$	4	$	4	0%
Research, development and engineering expenses	$	22	$	24	(8)%	$	68	$	80	(15)%
Equity earnings of affiliated companies	$	4	$	16	(75)%	$	13	$	32	(59)%
Net loss	$	(17)	$	(12)	*	$	(52)	$	(46)	*

* 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 9 (Investments) for additional information about Samsung Corning Precision and related party transactions.

The increase in this segment’s loss for the three and nine months ended September 30, 2011 was largely due to a decrease in equity earnings from Samsung Corning’s non-LCD glass businesses, offset somewhat by lower 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 three and nine months ended September 30, 2011 and 2010:

·   In the third quarter of 2011, Corning borrowed approximately $34 million on the credit facility that a wholly-owned subsidiary entered into in the second quarter of 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 $627 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 five years from the date of the first advance.  Amounts borrowed are being used to finance capital expenditures related to the construction of a LCD glass substrate facility in Beijing, China.

-46-

·   In the third quarter of 2010, we completed the following debt-related transactions:

o   We issued $400 million of 5.75% senior unsecured notes that mature on August 15, 2040 and $300 million of 4.25% senior unsecured notes that mature on August 15, 2020.  The net proceeds of $689 million from the offering were used to fund the repurchase of debt securities and for general corporate purposes.

o   We repurchased $126 million of our 6.2% senior unsecured notes due 2016 and $100 million of our 5.9% senior unsecured notes due 2014.  The net carrying amount of the debt repurchased was $234 million.  We recognized a pre-tax loss of $30 million upon the early redemption of these notes.

·   In the first quarter of 2010, we repaid $58 million of debt, which included the redemption of $48 million principal amount of our 6.25% notes due February 18, 2010.

On October 5, 2011, Corning’s Board of Directors declared a 50% increase in the company’s quarterly common stock dividend.  Corning’s quarterly dividend will increase from $0.05 per share to $0.075 per share of common stock.  The board also authorized a stock repurchase program for purchasing up to $1.5 billion of the company’s common stock.  The stock repurchase authorization expires at the end of 2013.

Capital Spending

Capital spending totaled $1.7 billion and $534 million for the nine months ended September 30, 2011 and 2010, respectively.  Spending increased at the end of nine months for 2011 largely as a result of several multi-year investment plans announced in 2010 that will increase manufacturing capacity in several of our operating segments.  Specifically, the increase in spending in the nine months ended September 30, 2011 was driven by construction costs for an LCD glass substrate facility in China for our Display Technologies segment and a capacity expansion project for Specialty Materials’ CorningÒ GorillaÒ glass in Japan.  We expect our 2011 capital spending to be approximately $2.4 billion.  Approximately $1.3 billion will be directed toward our Display Technologies segment.  Our 2012 capital spending program is expected to be approximately $1.8 billion.

Cash Flows

Summary of cash flow data (in millions):

	Nine months ended September 30,
	2011		2010
Net cash provided by operating activities	$	2,032	$	1,743
Net cash used in investing activities	$	(1,580)	$	(1,209)
Net cash (used in) provided by financing activities	$	(175)	$	173

Net cash provided by operating activities increased in the nine months ended September 30, 2011 when compared to the same period last year, due to a decrease in undistributed earnings of affiliated companies, lower pension contributions and cash received from our insurance carriers for the remainder of our settlement for business interruption and property damage claims for events occurring in 2009.  These events were partially offset by the decrease in cash from unfavorable movements in working capital and lower net income.

Net cash used in investing activities was higher in the nine months ended September 30, 2011 when compared to the same period last year, due to an increase in capital spending and a small acquisition completed in the first quarter of 2011.  Capital spending in the nine months ended September 30, 2010 was driven primarily by capacity projects to support growth in demand in our Display Technologies and Specialty Materials segments.

Net cash used in financing activities in the nine months ended September 30, 2011 increased when compared to the same period last year, driven primarily by the absence of proceeds received in the third quarter of 2010 from the issuance of $700 million face amount of unsecured notes and the increase in repayments of a capital lease.  These events were offset somewhat by the increase in proceeds received from the exercise of stock options and the absence of the retirement of long-term debt in the third quarter of 2010.

-47-

Customer Deposits

Certain customers of our Display Technologies segment have entered into long-term supply agreements and agreed to make advance cash deposits to secure supply of large-size glass substrates.  The deposits are reduced through future product purchases, thus reducing operating cash flows in later periods as credits are applied for deposits received in earlier periods.  Between 2004 and 2007, we received a total of $937 million for customer deposit agreements.  We received our last deposit of $105 million in July 2007 and do not expect to receive additional deposits related to these agreements.  During the nine months ended September 30, 2011 and 2010, we issued $21 million and $76 million, respectively, in credit memoranda.  Refer to Note 12 (Customer Deposits) to the consolidated financial statements for additional information.

Dividends from Equity Companies

Corning Hungary Data Services LLC and Samsung Electronics Corporation, as shareholders of Samsung Corning Precision, have agreed to have Samsung Corning Precision increase its annual dividend to shareholders from 40% to at least 70% of its net income from the previous year, subject to the maintenance of minimum cash balances.

Management Assessment of Liquidity

We ended the third quarter of 2011 with approximately $6.4 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 September 30, 2011, slightly more than half 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.  In the fourth quarter of 2010, we repatriated to the U.S. approximately $1.1 billion of 2010 earnings from certain foreign subsidiaries.  We expect previously accumulated non-U.S. cash balances will remain outside of the U.S.  In addition to the cash repatriated in 2010, 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 nine months ended September 30, 2011 and 2010 were not significant.  Volatility in financial markets may limit Corning’s access to capital markets and result in terms and conditions that by historical comparisons are more restrictive and costly to Corning.  Still, 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.

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 a measure of increased risk.  We closely monitor payments and 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 2011 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, 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 $627 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 September 30, 2011 and December 31, 2010, our leverage using this measure was 10% and 11%, 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 September 30, 2011 and December 31, 2010, our interest coverage ratio using this measure was 48.1 times and 40.2 times, respectively.  At September 30, 2011 and December 31, 2010, 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 September 30, 2011, 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.

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 2010 Form 10-K and remain unchanged through the third quarter of 2011.  For certain items, additional details are provided below.

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.

As of September 30, 2011 and December 31, 2010, we have not identified any instances where the carrying values of our long-lived assets were not recoverable.At September 30, 2011, the fair market value and our carrying value of precious metals were approximately equal, and at December 31, 2010, the fair market value of precious metals was higher than our carrying value by $415 million.  Currently these precious metal assets, primarily in the Display Technologies and Specialty Materials segments, are recoverable as part of their asset groupings. There is the potential for impairment 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 of the Display Technologies and Specialty Materials segments or a significant decrease in its profitability.

NEW ACCOUNTING STANDARDS

In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.  This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRS.  ASU 2011-04 is required to be applied prospectively in interim and annual periods beginning after December 15, 2011.  Early application is not permitted.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In June, 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income.  This statement requires companies to present the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements of net income and other comprehensive income.  This statement is effective for interim and annual periods beginning after December 15, 2011.  Early adoption is permitted and the amendments in this update will be applied retrospectively.  Corning will adopt this standard in the first quarter of 2012.

-50-

In September 2011, FASB issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment.  The Update simplifies how an entity tests goodwill for impairment.  It provides an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test.  Under that option, an entity no longer would be required to calculate the fair value of a reporting unit unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount.  The amendments will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.  Early adoption is permitted.  Corning will early adopt this standard during its fourth quarter impairment review process.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In September 2011, the FASB issued Accounting Standards Update No. 2011-09, Compensation—Retirement Benefits—Multiemployer Plans (Subtopic 715-80): Disclosures about an Employer’s Participation in a Multiemployer Plan.  The ASU 2011-09 amendments require additional disclosures about an employer's participation in a multiemployer plan.  ASU 2011-09 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years ending after December 15, 2011, with early adoption permitted.  Corning will not early adopt this standard and does not expect adoption of this standard to have a material impact on its consolidated results of operations and 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 September 30, 2011, and December 31, 2010, Corning had accrued approximately $30 million (undiscounted) 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 2010 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 2010 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 September 30, 2011, 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 September 30, 2011, 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.

Part II – Other Information

ITEM 1.  LEGAL PROCEEDINGS

Environmental Litigation.  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 September 30, 2011, and December 31, 2010, Corning had accrued approximately $30 million (undiscounted) 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.

Dow Corning Corporation.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.  The Plan also includes releases for Corning and Dow Chemical as shareholders in exchange for contributions to the Plan.

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 September 30, 2011, 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 September 30, 2011, Dow Corning has estimated the liability to commercial creditors to be within the range of $84 million to $277 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 $84 million, net of applicable tax benefits.  In addition, the London Market Insurers (the LMI Claimants) claimed a reimbursement right with respect to a portion of insurance proceeds previously paid by the LMI Claimants to Dow Corning.  This claim was based on a theory that the LMI Claimants overestimated Dow Corning’s liability for the resolution of implant claims pursuant to the Plan.  Based on settlement negotiations, Dow Corning had estimated that the most likely outcome would result in payment to the LMI Claimants in a range of $10 million to $20 million.  As of September 30, 2011, Dow Corning and the LMI Claimants have settled the claim for an amount within that range.  There are a number of other claims in the bankruptcy proceedings against Dow Corning awaiting resolution by the U.S. District Court, and it is reasonably possible that Dow Corning may record bankruptcy-related charges in the future.  The remaining tort claims against Corning are expected to be channeled by the Plan into facilities established by the Plan or otherwise defended by the Litigation Facility.

Hemlock Semiconductor Corporation, of which Dow Corning owns 63%, brought an action against one of its customers to enforce supply agreements requiring the customer to purchase or pay for large quantities of polycrystalline silicon used in the solar power industry.  The customer had previously announced its decision to exit the solar power business and denied its liability to purchase further products under existing supply agreements.

-54-

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.  At the time PCC filed for bankruptcy protection, there were approximately 11,800 claims pending against Corning in state court lawsuits alleging various theories of liability based on exposure to PCC’s asbestos products and typically requesting monetary damages in excess of one million dollars per claim.  Corning has defended those claims on the basis of the separate corporate status of PCC and the absence of any facts supporting claims of direct liability arising from PCC’s asbestos products.  Corning is also currently involved in approximately 10,200 other cases (approximately 38,600 claims) alleging injuries from asbestos and similar amounts of monetary damages per case.  Those cases have been covered by insurance without material impact to Corning to date.  As described below, several of Corning’s insurance carriers have filed a legal proceeding concerning the extent of any insurance coverage for these claims.  Asbestos litigation is inherently difficult, and past trends in resolving these claims may not be indicators of future outcomes.

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 courts and parties.  In 2003, a plan was agreed to by various parties (the 2003 Plan), but, on December 21, 2006, the Bankruptcy Court issued an order denying the confirmation of that 2003 Plan.  On January 29, 2009, an amended plan of reorganization (the Amended PCC Plan) – which addressed the issues raised by the Court when it denied confirmation of the 2003 Plan – was filed with the Bankruptcy Court.

The proposed resolution of PCC asbestos claims under the Amended PCC Plan would have required Corning to contribute its equity interests in PCC and Pittsburgh Corning Europe N.V. (PCE), a Belgian corporation, and to contribute a fixed series of payments, recorded at present value.  Corning would have had the option to use its shares rather than cash to make these payments, but the liability would have been fixed by dollar value and not the number of shares.  The Amended PCC Plan would, originally, have required Corning to make (1) one payment of $100 million one year from the date the Amended PCC Plan becomes effective and certain conditions are met and (2) five additional payments of $50 million, on each of the five subsequent anniversaries of the first payment, the final payment of which is subject to reduction based on the application of credits under certain circumstances.  Documents were filed with the Bankruptcy Court further modifying the Amended PCC Plan by reducing Corning’s initial payment by $30 million and reducing its second and fourth payments by $15 million each.  In return, Corning would relinquish its claim for reimbursement of its payments and contributions under the Amended PCC Plan from the insurance carriers involved in the bankruptcy proceeding with certain exceptions.

On June 16, 2011, the Court entered an Order denying confirmation of the Amended PCC Plan.  The Court’s memorandum opinion accompanying the order rejected some objections to the Amended PCC Plan and made suggestions regarding modifications to the Amended PCC Plan that would allow the Plan to be confirmed.  Corning and other parties have filed a motion for reconsideration, objecting to certain points of this order.  Certain parties to the proceeding filed specific plan modifications in response to the Court’s opinion and Corning supported these filings.  Objections to the modifications are to be filed by October 28, 2011 and responses to the objections by November 16, 2011.  The Court has set a hearing on the objections for November 30, 2011.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning.  Corning has recorded an additional $150 million for such claims in its estimated asbestos litigation liability.  The liability for non-PCC claims was estimated based upon industry data for asbestos claims since Corning does not have recent claim history due to the injunction issued by the Bankruptcy Court.  The estimated liability represents the undiscounted projection of claims and related legal fees over the next 20 years.  The amount may need to be adjusted in future periods as more data becomes available.

-55-

The Amended PCC Plan with the modifications addressing issues raised by the Court’s June 16 opinion remains subject to a number of contingencies.  Payment of the amounts required to fund the Amended PCC Plan from insurance and other sources are subject to a number of conditions that may not be achieved.  The approval of the (further modified) Amended PCC Plan by the Bankruptcy Court is not certain and faces objections by some parties.  If the modified Amended PCC Plan is approved by the Bankruptcy Court, that approval will be subject to appeal.  For these and other reasons, Corning’s liability for these asbestos matters may be subject to changes in subsequent quarters.  The estimate of the cost of resolving the non-PCC asbestos claims may also be subject to change as developments occur.  Management continues to believe that the likelihood of the uncertainties surrounding these proceedings causing a material adverse impact to Corning’s financial statements is remote.

Several of Corning’s insurers have commenced litigation in state courts for a declaration of the rights and obligations of the parties under insurance policies, including rights that may be affected by the potential resolutions described above.  Corning is vigorously contesting these cases.  Management is unable to predict the outcome of this insurance litigation and therefore cannot estimate the range of any possible loss.

Seoul Guarantee Insurance Co. and other creditors against Samsung Group and affiliates.Prior to their merger, Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) and Samsung Corning Co. Ltd. (Samsung Corning) were two of approximately thirty co-defendants in a lawsuit filed by Seoul Guarantee Insurance Co. and thirteen other creditors (SGI and Creditors) for alleged breach of an agreement that approximately twenty-eight affiliates of the Samsung group (Samsung Affiliates) entered into with SGI and Creditors on August 24, 1999 (the Agreement).  The lawsuit is pending in the courts of South Korea.  Under the Agreement, it is alleged that the Samsung Affiliates agreed to sell certain shares of Samsung Life Insurance Co., Ltd. (SLI), which had been transferred to SGI and Creditors in connection with the petition for court receivership of Samsung Motors Inc.  In the lawsuit, SGI and Creditors allege a breach of the Agreement by the Samsung Affiliates and are seeking the loss of principal (approximately $1.95 billion) for loans extended to Samsung Motors Inc., default interest and a separate amount for breach.  On January 31, 2008, the Seoul District Court ordered the Samsung Affiliates: to pay approximately $1.3 billion by disposing of 2,334,045 shares of SLI less 1,165,955 shares of SLI previously sold by SGI and Creditors and paying the proceeds to SGI and Creditors; to satisfy any shortfall by participating in the purchase of equity or subordinate debentures issued by them; and pay default interest of 6% per annum.  The ruling was appealed.  On November 10, 2009, the Appellate Court directed the parties to attempt to resolve this matter through mediation.  On January 11, 2011, the Appellate Court ordered the Samsung Affiliates to pay 600 billion won in principal and 20 billion won in delayed interest to SGI and Creditors.  Samsung promptly paid those amounts, which approximated $550 million when translated to United States dollars, from a portion of an escrow account established upon completion of SLI’s initial public offering (“IPO”) on May 7, 2010.  On February 7, 2011, the Samsung Affiliates appealed the Appellate Court’s ruling to the Supreme Court of Korea and the appeal is currently in progress.  Samsung Corning Precision has not contributed to any payment related to these disputes, and has concluded that no provision for loss should be reflected in its financial statements.  Other than as described above, no claim in these matters has been asserted against Corning or any of its affiliates.

Ellsworth Industrial Park, Downers Grove, IL Environmental Litigation.Corning has settled claims for contribution for personal injury and property damage arising from the alleged release of solvents from the operations of several corporate defendants at the Ellsworth Industrial Park into soil and groundwater.  Corning has also settled a cost-recovery action by the State of Illinois against a number of corporate defendants as a result of an alleged groundwater contamination at this industrial park site.  Two additional corporate defendants have made claims for contribution for property damage and cost recovery for remediations at this industrial park site, one of which has been voluntarily dismissed as to Corning.  The second case was dismissed by the Court on August 12, 2009.  On November 17, 2009, the Court denied plaintiff’s request to file an amended complaint.  On December 14, 2009, plaintiff gave notice of its appeal of the District Court’s opinion and order dismissing its case to the U.S. Court of Appeals for the Seventh Circuit.  On November 10, 2010, the Court of Appeals reversed the District Court and reinstated the case.  At a February 3, 2011 status conference, the District Court set a date for responses to plaintiff’s complaint.  On March 7, 2011, Corning filed a motion to dismiss the complaint.  On August 11, 2011, the District Court granted Corning’s motion to dismiss.  On August 15, 2011, the case was settled by agreement with respect to Corning’s subsidiary, H.W. Holding Co.

Commission of European Communities Competition Investigation.In connection with an investigation by the Commission of the European Communities, Competition DG, of alleged anticompetitive behavior relating to the worldwide production of LCD glass, Corning and Samsung Corning Precision received requests for information from the Competition DG on March 30, 2009 and October 9, 2009.  Each party has responded to these requests.  Samsung Corning Precision has also responded to the Competition DG and authorities in other jurisdictions, including the United States, in connection with similar investigations of alleged anticompetitive behavior relating to worldwide production of cathode ray tube glass.  On October 7, 2011, Samsung Corning Precision was informed by the Antitrust Division of the U.S. Department of Justice (“DOJ”) that the DOJ had closed its investigation of cathode ray tube glass.  On October 19, 2011, the European Commission announced that it had settled its cartel investigation of cathode ray tube glass.  Samsung Corning Precision received full immunity, and no fines were imposed on it, because of its early cooperation in the Commission’s investigation.  The Commission fined three other makers of cathode ray tube glass.

Supply Disputes.  Corning has notified customers of its Environmental Technologies segment that it will be unable to fully supply all future requests for certain diesel products, but will honor its existing legal obligations.  At least one customer has taken the position that Corning has a legal obligation to supply its requirements for these products for some time in the future despite the absence of an executed supply agreement or accepted purchase orders.  In response, Corning has indicated it does not agree with the customer’s position and Corning is under no current obligation to provide these products in the future to that customer.  Corning has filed an action for a declaratory judgment in the Western District of New York seeking confirmation of Corning’s position on these issues.  Corning continues to discuss an appropriate resolution of supply matters with other customers.

Chinese Antidumping Investigation.  On April 22, 2010, the Chinese Ministry of Commerce initiated an antidumping investigation against manufacturers of optical fiber based in the U.S. and the European Union, alleging that standard single-mode optical fiber was sold in China at lower prices than in the respective home country.  This matter does not present a claim for damages, but the Ministry may prospectively impose additional duties on imported fiber products.  On April 21, 2011, the Chinese authorities issued a final decision finding a dumping margin of approximately 5.4% on certain optical fiber imported by Corning into China, having previously rejected Corning’s arguments against the imposition of such duties.

Demodulation, Inc.  On January 18, 2011, Demodulation, Inc. filed suit in the U.S. District Court for the District of New Jersey against Applied DNA Sciences, Inc., Corning Incorporated, Alfred University, Alfred Technology Resources, Inc., and John and Jane Does 1-10.  Demodulation filed an amended complaint on August 3, 2011, alleging a conspiracy by the defendants to steal Demodulation’s alleged trade secrets and other intellectual property related to glass covered amorphous metal microwires and seeks damages under various theories, including breach of contract, defamation, conspiracy, antitrust, unfair competition, interference with prospective business relations and misappropriation of trade secrets.  Corning does not believe Demodulation’s allegations have merit and intends to defend the case vigorously.  Recognizing that the outcome of litigation is uncertain, management believes that the likelihood of a materially adverse impact to Corning's financial statements is remote.

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. (“SCP”) filed suits in the Daejeon District Court against Dongxu, one of its officers, and two other named individuals, for related trade secret misappropriation.  SCP is an equity company between Corning and Samsung Electronics Co., Ltd., which uses Corning LCD glass technology under license agreements with Corning.  In these actions, Corning is seeking monetary damages and 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 SCP.

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

	Amortized cost				Fair value
	September 30, 2011		December 31, 2010		September 30, 2011		December 31, 2010
Bonds, notes and other securities:

Total short-term investments	$	1,513	$	1,745	$	1,520	$	1,752
Asset-backed securities	$	59	$	64	$	38	$	45
Total long-term investments	$	59	$	64	$	38	$	45

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 September 30, 2011 (in millions):

Less than one year	$1,193
Due in 1-5 years	319
Due in 5-10 years
Due after 10 years (1)	46
Total	$1,558

(1) Includes $38 million of asset-based securities that mature over time and are being reported at their final maturity dates.

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 September 30, 2011 and December 31, 2010 (in millions):

		September 30, 2011

Total long-term investments	22	$	45	$	(20)	$	45	$	(20)

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

Gross realized gains and losses for the three and nine months ended September 30, 2011 and 2010 were not significant.

A reconciliation of the changes in credit losses recognized in earnings for the nine months ended September 30, 2011 and nine months ended September 30, 2010 (in millions):

	2011	2010
Beginning balance of credit losses, January 1	$ 4	$ 2
Additions for credit losses not previously recognized in earnings
Balance of credit losses, March 31	$ 4	$ 2
Additions for credit losses not previously recognized in earnings	1	1
Ending balance of credit losses, June 30	$ 5	$ 3
Additions for credit losses not previously recognized in earnings
Ending balance of credit losses, September 30	$ 5	$ 3

The $5 million loss represents management's estimate of credit losses inherent in the securities considering projected cash flows using assumptions of delinquency rates, loss severities, and other estimates of future collateral performance.  These credit losses are limited to asset-backed securities in our investment portfolio.

As of September 30, 2011 and December 31, 2010, for securities that have credit losses, an other than temporary impairment loss of $16 million in both periods is recognized in accumulated other comprehensive income.

Proceeds from sales and maturities of short-term investments totaled $2.4 billion and $1.3 billion for the nine months ended September 30, 2011 and 2010, respectively.

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, 2010 (2010 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.

Fair Value Measurements

Fair Value Measurements

Major categories of financial assets and liabilities, including short-term investments, other assets and derivatives are measured at fair value on a recurring basis.  Certain assets and liabilities including long-lived assets, goodwill, asset retirement obligations, and cost and equity investments are measured at fair value on a nonrecurring basis.

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

Customer Deposits

12.      Customer Deposits

In 2005 and 2004, several of Corning's customers entered into long-term purchase and supply agreements in which Corning's Display Technologies segment would supply large-size glass substrates to these customers over periods of up to six years.  As part of the agreements, these customers agreed to advance cash deposits to Corning for a portion of the contracted glass to be purchased.  Between 2004 and 2007, we received a total of $937 million for customer deposit agreements.  We do not expect to receive additional deposits related to these agreements.

Upon receipt of the cash deposits made by customers, we recorded a customer deposit liability.  This liability is reduced at the time of future product sales over the life of the agreements.  As product is shipped to a customer, Corning recognizes revenue at the selling price and issues credit memoranda for an agreed amount of the customer deposit liability.  The credit memoranda are applied against customer receivables resulting from the sale of product, thus reducing operating cash flows in later periods as these credits are applied to cash deposits received in earlier periods.

During the three and nine months ended September 30, 2011, we issued $7 million and $21 million, respectively, in credit memoranda.  During the three and nine months ended September 30, 2010, we issued $8 million and $76 million, respectively, in credit memoranda.  Customer deposit liabilities were $7 million and $27 million at September 30, 2011 and December 31, 2010, respectively, which are recorded in the current portion of other accrued liabilities in our consolidated balance sheets.  Because these liabilities are denominated in Japanese yen, changes in the balances include the impact of movements in the Japanese yen-U.S. dollar exchange rate.

In the event customers do not purchase the agreed upon quantities of product, subject to specific conditions outlined in the agreements, Corning may retain certain amounts of the customer deposits.  If Corning does not deliver agreed upon product quantities, subject to specific conditions outlined in the agreements, Corning may be required to return certain amounts of customer deposits.

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.  At the time PCC filed for bankruptcy protection, there were approximately 11,800 claims pending against Corning in state court lawsuits alleging various theories of liability based on exposure to PCC's asbestos products and typically requesting monetary damages in excess of one million dollars per claim.  Corning has defended those claims on the basis of the separate corporate status of PCC and the absence of any facts supporting claims of direct liability arising from PCC's asbestos products.  Corning is also currently involved in approximately 10,200 other cases (approximately 38,600 claims) alleging injuries from asbestos and similar amounts of monetary damages per case.  Those cases have been covered by insurance without material impact to Corning to date.  As described below, several of Corning's insurance carriers have filed a legal proceeding concerning the extent of any insurance coverage for these claims.  Asbestos litigation is inherently difficult, and past trends in resolving these claims may not be indicators of future outcomes.

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 courts and parties.  In 2003, a plan was agreed to by various parties (the 2003 Plan), but, on December 21, 2006, the Bankruptcy Court issued an order denying the confirmation of that 2003 Plan.  On January 29, 2009, an amended plan of reorganization (the Amended PCC Plan) – which addressed the issues raised by the Court when it denied confirmation of the 2003 Plan – was filed with the Bankruptcy Court.

The proposed resolution of PCC asbestos claims under the Amended PCC Plan would have required Corning to contribute its equity interests in PCC and Pittsburgh Corning Europe N.V. (PCE), a Belgian corporation, and to contribute a fixed series of payments, recorded at present value.  Corning would have had the option to use its shares rather than cash to make these payments, but the liability would have been fixed by dollar value and not the number of shares.  The Amended PCC Plan would, originally, have required Corning to make (1) one payment of $100 million one year from the date the Amended PCC Plan becomes effective and certain conditions are met and (2) five additional payments of $50 million, on each of the five subsequent anniversaries of the first payment, the final payment of which is subject to reduction based on the application of credits under certain circumstances.  Documents were filed with the Bankruptcy Court further modifying the Amended PCC Plan by reducing Corning's initial payment by $30 million and reducing its second and fourth payments by $15 million each.  In return, Corning would relinquish its claim for reimbursement of its payments and contributions under the Amended PCC Plan from the insurance carriers involved in the bankruptcy proceeding with certain exceptions.

On June 16, 2011, the Court entered an Order denying confirmation of the Amended PCC Plan.  The Court's memorandum opinion accompanying the order rejected some objections to the Amended PCC Plan and made suggestions regarding modifications to the Amended PCC Plan that would allow the Plan to be confirmed.  Corning and other parties have filed a motion for reconsideration, objecting to certain points of this order.  Certain parties to the proceeding filed specific plan modifications in response to the Court's opinion and Corning supported these filings.  Objections to the modifications are to be filed by October 28, 2011 and responses to the objections by November 16, 2011.  The Court has set a hearing on the objections for November 30, 2011.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning.  Corning has recorded an additional $150 million for such claims in its estimated asbestos litigation liability.  The liability for non-PCC claims was estimated based upon industry data for asbestos claims since Corning does not have recent claim history due to the injunction issued by the Bankruptcy Court.  The estimated liability represents the undiscounted projection of claims and related legal fees over the next 20 years.  The amount may need to be adjusted in future periods as more data becomes available.

The liability for the Amended PCC Plan and the non-PCC asbestos claims was estimated to be $649 million at September 30, 2011, compared with an estimate of the liability of $633 million at December 31, 2010.  In the three and nine months ended September 30, 2011, Corning recorded asbestos litigation expense of $5 million and $15 million, respectively.  In the three months and nine months ended September 30, 2010, Corning recorded asbestos litigation expense of $6 million and $13 million, respectively.  In addition, during the first quarter of 2010, Corning recorded a $54 million credit to the asbestos litigation reserve related to the change in terms of the proposed settlement of the PCC asbestos claims.  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).

The Amended PCC Plan with the modifications addressing issues raised by the Court's June 16 opinion remains subject to a number of contingencies.  Payment of the amounts required to fund the Amended PCC Plan from insurance and other sources are subject to a number of conditions that may not be achieved.  The approval of the (further modified) Amended PCC Plan by the Bankruptcy Court is not certain and faces objections by some parties.  If the modified Amended PCC Plan is approved by the Bankruptcy Court, that approval will be subject to appeal.  For these and other reasons, Corning's liability for these asbestos matters may be subject to changes in subsequent quarters.  The estimate of the cost of resolving the non-PCC asbestos claims may also be subject to change as developments occur.  Management continues to believe that the likelihood of the uncertainties surrounding these proceedings causing a material adverse impact to Corning's financial statements is remote.

Several of Corning's insurers have commenced litigation in state courts for a declaration of the rights and obligations of the parties under insurance policies, including rights that may be affected by the potential resolutions described above.  Corning is vigorously contesting these cases.  Management is unable to predict the outcome of this insurance litigation and therefore cannot estimate the range of any possible loss.

Other Commitments and Contingencies

In the normal course of our business, we do not routinely provide significant third-party guarantees.  When provided, these guarantees have various terms, and none of these guarantees are individually significant.  Generally, 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.  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 September 30, 2011 and December 31, 2010, contingent guarantees totaled a notional value of $176 million and $230 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 $265 million and $408 million, at September 30, 2011 and December 31, 2010, respectively.

Product warranty liability accruals were $25 million at September 30, 2011 and $24 million at December 31, 2010.

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.

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 September 30, 2011, and December 31, 2010, Corning had accrued approximately $30 million (undiscounted) 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.

(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.

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

As of September 30, 2011, balances due from Samsung Corning Precision were $35 million and balances due to Samsung Corning Precision were $11 million.  As of December 31, 2010, balances due from Samsung Corning Precision were $29 million and balances due to Samsung Corning Precision were $5 million.

In April 2011, Korean tax authorities completed a tax audit of Samsung Corning Precision.  As a result, the tax authorities issued a pre-assessment of approximately $45 million for an asserted underpayment of withholding tax on dividends paid from September 2006 through March 2009.  Our first level of appeal was denied on October 5, 2011 and a formal assessment was issued.  The assessment will be paid in full by the end of 2011, which will allow us to continue the appeal process.  Samsung Corning Precision and Corning believe we will maintain our position when all available appeal remedies have been exhausted.

Additionally, the Korean Board of Audit and Inspection (the "BOAI") has recently initiated a review of tax exemptions previously granted to Samsung Corning Precision by the National Tax Service.  The BOAI has the authority to reverse part or all of the tax exemption granted, at which time the decision may be appealed.  We believe that SCP should sustain its entire tax exemption.  SCP is unable to make a reasonable estimate of additional tax that could potentially result from the BOAI review.

On December 31, 2007, Samsung Corning Precision acquired all of the outstanding shares of Samsung Corning Co., Ltd. (Samsung Corning).  After the transaction, Corning retained its 50% interest in Samsung Corning Precision.  Prior to their merger, Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) and Samsung Corning Co. Ltd. (Samsung Corning) were two of approximately thirty co-defendants in a lawsuit filed by Seoul Guarantee Insurance Co. and thirteen other creditors (SGI and Creditors) for alleged breach of an agreement that approximately twenty-eight affiliates of the Samsung group (Samsung Affiliates) entered into with SGI and Creditors on August 24, 1999 (the Agreement).  The lawsuit is pending in the courts of South Korea.  Under the Agreement, it is alleged that the Samsung Affiliates agreed to sell certain shares of Samsung Life Insurance Co., Ltd. (SLI), which had been transferred to SGI and Creditors in connection with the petition for court receivership of Samsung Motors Inc.  In the lawsuit, SGI and Creditors allege a breach of the Agreement by the Samsung Affiliates and are seeking the loss of principal (approximately $1.95 billion) for loans extended to Samsung Motors Inc., default interest and a separate amount for breach.  On January 31, 2008, the Seoul District Court ordered the Samsung Affiliates: to pay approximately $1.3 billion by disposing of 2,334,045 shares of SLI less 1,165,955 shares of SLI previously sold by SGI and Creditors and paying the proceeds to SGI and Creditors; to satisfy any shortfall by participating in the purchase of equity or subordinate debentures issued by them; and pay default interest of 6% per annum.  The ruling was appealed.  On November 10, 2009, the Appellate Court directed the parties to attempt to resolve this matter through mediation.  On January 11, 2011, the Appellate Court ordered the Samsung Affiliates to pay 600 billion won in principal and 20 billion won in delayed interest to SGI and Creditors.  Samsung promptly paid those amounts, which approximated $550 million when translated to United States Dollars, from a portion of an escrow account established upon completion of SLI's initial public offering ("IPO") on May 7, 2010.  On February 7, 2011, the Samsung Affiliates appealed the Appellate Court's ruling to the Supreme Court of Korea and the appeal is currently in progress.  Samsung Corning Precision has not contributed to any payment related to these disputes, and has concluded that no provision for loss should be reflected in its financial statements.  Other than as described above, no claim in these matters has been asserted against Corning or any of its affiliates.

In connection with an investigation by the Commission of the European Communities, Competition DG, of alleged anticompetitive behavior relating to the worldwide production of LCD glass, Corning and Samsung Corning Precision received requests for information from the Competition DG on March 30, 2009 and October 9, 2009.  Each party has responded to these requests.  Samsung Corning Precision has also responded to the Competition DG and authorities in other jurisdictions, including the United States, in connection with similar investigations of alleged anticompetitive behavior relating to worldwide production of cathode ray tube glass.  On October 7, 2011, Samsung Corning Precision was informed by the Antitrust Division of the U.S. Department of Justice ("DOJ") that the DOJ had closed its investigation of cathode ray tube glass.  On October 19, 2011, the European Commission announced that it had settled its cartel investigation of cathode ray tube glass.  Samsung Corning Precision received full immunity, and no fines were imposed on it, because of its early cooperation in the Commission's investigation.  The Commission fined three other makers of cathode ray tube glass.

In September 2009, Corning and Samsung Corning Precision formed Corsam Technologies LLC (Corsam), a new equity affiliate established to provide glass technology research for future product applications.  Samsung Corning Precision invested $124 million in cash and Corning contributed intellectual property with a corresponding value.  Corning and Samsung Corning Precision each own 50% of the common stock of Corsam and Corning has agreed to provide research and development services at arms length to Corsam.  Corning does not control Corsam because Samsung Corning Precision's other investors maintain significant participating voting rights.  In addition, Corsam has sufficient equity to finance its activities, the voting rights of investors in Corsam are considered substantive, and the risks and rewards of Corsam's research are shared only by those investors noted.  As a result, Corsam is accounted for under the equity method of accounting for investments.

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):

Statement of Operations:
Net sales	$	1,661	$	1,515	$	4,908	$	4,413

Related Party Transactions:

Dividends received from Dow Corning	$	65	$	56	$	245	$	167

Amounts owed to Dow Corning totaled $2 million as of September 30, 2011.  At December 31, 2010, amounts owed to Dow Corning were not significant.

At September 30, 2011, Dow Corning's marketable securities included approximately $255 million of auction rate securities, net of a temporary impairment of $36 million.  As a result of the temporary impairment, unrealized losses of $30 million, net of $6 million for a minority interest's share, were included in accumulated other comprehensive income in Dow Corning's consolidated balance sheet.  Corning's share of this unrealized loss was $15 million and is included in Corning's accumulated other comprehensive income.

In February 2011, Dow Corning amended and restated its revolving credit agreement to provide $1 billion senior, unsecured revolving line of credit through February 2016.  Dow Corning believes it has adequate liquidity to fund operations, its capital expenditure plans, breast implant settlement liabilities, and shareholder dividends.

In 1995, Corning fully impaired its investment in Dow Corning after it filed for bankruptcy protection.  Corning did not recognize net equity earnings from the second quarter of 1995 through the end of 2002.  Corning began recognizing equity earnings in the first quarter of 2003 when management concluded that Dow Corning's emergence from bankruptcy was probable.  Corning considers the $249 million difference between the carrying value of its investment in Dow Corning and its 50% share of Dow Corning's equity to be permanent.

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.  The Plan also includes releases for Corning and Dow Chemical as shareholders in exchange for contributions to the Plan.

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 September 30, 2011, 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 September 30, 2011, Dow Corning has estimated the liability to commercial creditors to be within the range of $84 million to $277 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 $84 million, net of applicable tax benefits.  In addition, the London Market Insurers (the LMI Claimants) claimed a reimbursement right with respect to a portion of insurance proceeds previously paid by the LMI Claimants to Dow Corning.  This claim was based on a theory that the LMI Claimants overestimated Dow Corning's liability for the resolution of implant claims pursuant to the Plan.  Based on settlement negotiations, Dow Corning had estimated that the most likely outcome would result in payment to the LMI Claimants in a range of $10 million to $20 million.  As of September 30, 2011, Dow Corning and the LMI Claimants have settled the claim for an amount within that range.  There are a number of other claims in the bankruptcy proceedings against Dow Corning awaiting resolution by the U.S. District Court, and it is reasonably possible that Dow Corning may record bankruptcy-related charges in the future.  The remaining tort claims against Corning are expected to be channeled by the Plan into facilities established by the Plan or otherwise defended by the Litigation Facility.

Hemlock Semiconductor Corporation, of which Dow Corning owns 63%, brought an action against one of its customers to enforce supply agreements requiring the customer to purchase or pay for large quantities of polycrystalline silicon used in the solar power industry.  The customer had previously announced its decision to exit the solar power business and denied its liability to purchase further products under existing supply agreements.

(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.  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 settlement for asbestos litigation.  At September 30, 2011 and December 31, 2010, the fair value of PCE significantly exceeded its carrying value of $137 million and $129 million, respectively.  There have been no impairment indicators for our investment in PCE and we continue to recognize equity earnings of this affiliate.  PCC filed for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Western District of Pennsylvania on April 16, 2000.  At that time, Corning determined that it lacked the ability to recover the carrying amount of its investment in PCC and its investment was other-than-temporarily impaired.  As a result, we reduced our investment in PCC to zero.  Refer to Note 3 (Commitments and Contingencies) for additional information about PCC and PCE.

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 four variable interest entities that are not considered significant to Corning's consolidated financial statements.  Corning does not have retained interests in assets transferred to an unconsolidated entity that serve as credit, liquidity or market risk support to that entity.

Hedging Activities

Hedging Activities

Hedging Activities

14.      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 exposure 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 counterparty default.  Neither we nor our counterparties are required to post collateral for these financial instruments.

The amount of hedge ineffectiveness at September 30, 2011 and at December 31, 2010 was insignificant.

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.  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 September 30, 2011, the amount of net losses expected to be reclassified into earnings within the next 12 months is $24 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.

Net Investment in Foreign Operations

In February 2000, we issued $500 million of Euro-denominated notes that were designated as a hedge of a net investment in foreign operations.  The effective portion of the changes in fair value of the outstanding debt balance has been included as a component of the foreign currency translation adjustment (CTA) within accumulated other comprehensive income (loss).  In February 2010, we repaid the remaining $48 million balance of this debt.  At that time, the cumulative amount of CTA related to this debt was a net loss of $140 million, which will remain in accumulated other comprehensive income until ultimate disposition of the underlying Euro investment.

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, 2010 (2010 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.

Fair Value Measurements

Major categories of financial assets and liabilities, including short-term investments, other assets and derivatives are measured at fair value on a recurring basis.  Certain assets and liabilities including long-lived assets, goodwill, asset retirement obligations, and cost and equity investments are measured at fair value on a nonrecurring basis.

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

New Accounting Standards

In May, 2011, the FASB issued Accounting Standards Update No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.  This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRS.  ASU 2011-04 is required to be applied prospectively in interim and annual periods beginning after December 15, 2011.  Early application is not permitted.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In June, 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income.  This statement requires companies to present the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements of net income and other comprehensive income.  This statement is effective for interim and annual periods beginning after December 15, 2011.  Early adoption is permitted and the amendments in this update will be applied retrospectively.  Corning will adopt this standard in the first quarter of 2012.

In September 2011, FASB issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment.  This update simplifies how an entity tests goodwill for impairment.  It provides an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test.  Given this option, an entity no longer would be required to calculate the fair value of a reporting unit unless the entity determines, based on that qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount.  The amendments will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.  Early adoption is permitted.  Corning will early adopt this standard during its fourth quarter impairment review process.  Corning does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

In September 2011, the FASB issued Accounting Standards Update No. 2011-09, Compensation—Retirement Benefits—Multiemployer Plans (Subtopic 715-80): Disclosures about an Employer's Participation in a Multiemployer Plan.  The ASU 2011-09 amendments require additional disclosures about an employer's participation in a multiemployer plan.  ASU 2011-09 is required to be applied retrospectively for all prior periods presented and is effective for annual periods for fiscal years ending after December 15, 2011, with early adoption permitted.  Corning will not early adopt this standard and does not expect adoption of this standard to have a material impact on its consolidated results of operations and financial condition.

Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $2.6 billion at September 30, 2011 and $2.4 billion at December 31, 2010.

Third Quarter

In the third quarter of 2011, Corning borrowed approximately $34 million on the credit facility that a wholly-owned subsidiary entered into in the second quarter of 2011.

In the third quarter of 2010, we issued $400 million of 5.75% senior unsecured notes and $300 million of 4.25% senior unsecured notes for net proceeds of approximately $394 million and $295 million, respectively.  The 5.75% notes mature on August 15, 2040 and the 4.25% notes mature on August 15, 2020.  We may redeem these notes at any time.

In the third quarter of 2010, we repurchased $126 million of 6.2% senior unsecured notes due March 15, 2016 and $100 million of 5.9% senior unsecured notes due March 15, 2014.  The net carrying amount of the debt repurchased was $234 million.  We recognized a pre-tax loss of $30 million upon early redemption of these notes.

Second Quarter

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 $627 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 five years from the date of the first advance.

First Quarter

In the first quarter of 2010, Corning repaid $58 million of debt, which included the redemption of $48 million principal amount of our 6.25% notes due February 18, 2010.

Income Taxes

5.      Income Taxes

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

	Three months ended September 30,				Nine months ended September 30,
	2011		2010		2011		2010
Provision for income taxes	$	(110)	$	(14)	$	(347)	$	(142)
Effective tax rate		11.9%		1.8%		13.0%		5.3%

For the three and nine months ended September 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/(losses) of consolidated foreign companies;

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions; and

·   The impact of discrete items, including a $22 million non-taxable reduction to a contingent liability associated with an acquisition recorded in the first quarter of 2011 and a $41 million tax benefit from amending our 2006 U.S. Federal return to claim foreign tax credits.  Discrete items decreased our effective tax rate by 4.1 and 1.4 percentage points for the three and nine months ended September 30, 2011, respectively.

For the three months ended September 30, 2010, the effective income tax rate differed from the U.S. statutory rate of 35% primarily due to the following items:

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

·   The impact of equity in earnings of affiliated companies;

·   The benefit of tax holidays and investment credits in foreign jurisdictions;

·   The benefit of excess foreign tax credits from repatriation of current year earnings of certain foreign subsidiaries; and

·   The impact of discrete items, including a $30 million loss from early redemption of debt.  Refer to Note 4 (Debt) for additional information about Corning's debt redemption loss.  Discrete items decreased our effective tax rate by 0.6 percentage points.

In addition to the items noted above, the tax provision for the nine months ended September 30, 2010 reflected the impact of discrete items, including a $56 million charge from the reversal of the deferred tax asset associated with a subsidy for certain retiree medical benefits.  Discrete items in the nine months ended September 30, 2010 increased our effective tax rate by 2.5 percentage points.

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 2.3 and 2.8 percentage points for the three months ended September 30, 2011 and 2010, respectively.  The impact of the tax holidays on our effective tax rate is a reduction in the rate of 1.7 and 3.2 percentage points for the nine months ended September 30, 2011 and 2010, respectively.

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.

Under U.S. GAAP, a deferred tax liability should be recorded for any book basis greater than tax basis in a foreign subsidiary attributable to unremitted book earnings under the presumption that such earnings will ultimately be distributed and that such distribution would be subject to additional tax at the parent company level.  However, such presumption is rebuttable and no tax would be accrued to the extent the temporary difference is not expected to reverse in the foreseeable future because the unremitted foreign earnings are expected to be reinvested indefinitely.

As required by U.S. GAAP, Corning completes an annual detailed analysis to determine the extent to which its foreign unremitted earnings are indefinitely reinvested considering various factors including the following:

·   U.S. cash needs and liquidity;

·   International working capital, debt service and capital expansion needs;

·   Local regulatory, statutory or other legally enforceable restrictions on the distribution of foreign subsidiary and affiliate earnings;

·   Foreign joint venture agreement limitations on distributions; and

·   The current and/or future tax costs associated with repatriation, including potential legislative changes that could impact such costs.

Quarterly, Corning updates its analysis for material changes.

In the quarter ended March 31, 2010, Corning included in the computation of its estimated annual effective tax rate a tax benefit of $265 million related to an expected fourth quarter repatriation of $1.1 billion of 2010 foreign earnings.  The repatriated earnings represented a portion of the current year earnings of certain foreign subsidiaries and affiliates located in Asia and thus were not previously permanently reinvested.

There were two factors influencing Corning's decision to consider repatriating these 2010 earnings.  One was Corning's decision, as announced early in 2010, to pursue acquisitions that were expected to require cash to be available in the U.S. in excess of amounts expected to be generated from domestic sources.  The second factor was proposed federal tax legislation which, if enacted, could significantly increase the tax cost of repatriation after 2010.  Because there had been no change in our longer term international capital expansion plans as of the first quarter, our intent to indefinitely reinvest foreign earnings accumulated through the year ended December 31, 2009 was not changed by these factors.

As of the year ended December 31, 2010, Corning had $8.9 billion of foreign unremitted earnings that it intends to keep indefinitely reinvested.  It is not practical to calculate the unrecognized deferred tax liability on those earnings with reasonable accuracy.

Of this amount, nearly 70% consists of:

·   Non-liquid operating assets or short term liquidity required to meet current international working capital needs; and

·   SCP or other joint venture unremitted earnings that require a joint determination with our partners to remove any indefinitely reinvested representation.

Additionally, in the third quarter of 2010, Corning announced a significant multi-year investment plan that was expected to result in 2011 capital investment of $2.4 billion to $2.7 billion, the substantial majority of which would be spent internationally and would include over the term of the plan: $800 million for additional LCD capacity in China; capacity expansion for Eagle XG LCD glass and CorningÒ GorillaÒ Glass in Asia; expansion of automotive substrate facilities in China and Germany; and a new manufacturing and distribution center in China for our Life Sciences businesses.  These factors in addition to the fact that Corning has sufficient access to funds in the U.S. to fund currently anticipated domestic needs result in our ability and intent to indefinitely reinvest our foreign unremitted earnings of $8.9 billion as of December 31, 2010.

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.  In response to rising health care costs, we changed our cost-sharing approach for retiree medical coverage.  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.  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.

Share-Based Compensation

Share-Based Compensation

Share-Based Compensation

16.      Share-based Compensation

Stock Compensation Plans

The Company measures and recognizes compensation cost for all share-based payment awards made to employees and directors, including grants of employee stock options and employee stock purchases related to the Worldwide Employee Share Purchase Plan (WESPP), based on estimated fair values.  Fair values for stock options granted prior to January 1, 2010 were estimated using a lattice-based binomial valuation model.  In 2010, Corning began estimating fair values for stock options granted using a multiple-point Black-Scholes model.  Both models incorporate the required assumptions and meet the fair value measurement objective under U.S. GAAP.

Share-based compensation cost was approximately $21 million and $22 million for the three months ended September 30, 2011 and 2010, respectively, and approximately $66 million and $77 million for the nine months ended September 30, 2011 and 2010, 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.  On February 3, 2010, Corning's Board of Directors approved the recommendation to terminate on-going WESPP contributions effective March 31, 2010.  Compensation expense for the WESPP is included in periods ended prior to April 1, 2010.

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 nine months ended September 30, 2011:

	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, 2010	72,461	$16.22
Granted	5,288	21.15
Exercised	(7,228)	11.49
Forfeited and Expired	(4,255)	36.79
Options Outstanding as of September 30, 2011	66,266	15.81	4.95	114,629
Options Exercisable as of September 30, 2011	52,372	15.52	4.09	102,861

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 September 30, 2011, which would have been received by the option holders had all option holders exercised their options as of that date.

As of September 30, 2011, there was approximately $36 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 2 years.  Compensation cost related to stock options was approximately $37 million and $41 million for the nine months ended September 30, 2011 and 2010, respectively, and approximately $12 million for the three months ended September 30, 2011 and 2010.

Proceeds received from the exercise of stock options were $82 million and $39 million for the nine months ended September 30, 2011 and 2010, respectively, and $9 million and $10 million for the three months ended September 30, 2011 and 2010, 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 nine months ended September 30, 2011 and 2010 was approximately $71 million and $41 million, respectively, and $3 million and $9 million for the three months ended September 30, 2011 and 2010, 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 5 (Income Taxes) to the consolidated financial statements.

Corning used a binomial lattice model to estimate the fair values of stock option grants through December 31, 2009.  Effective January 1, 2010, Corning began using a multiple-point Black-Scholes model to estimate the fair value of stock option grants.  The financial impact of the change in valuation models is insignificant.

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

	Three months ended September 30,		Nine months ended September 30,
	2011	2010	2011	2010
Expected volatility	48-49%	49%	47-49%	48-49%
Weighted-average volatility	48%	49%	47-48%	49%
Expected dividends	1.05%	1.15%	1.10%	1.15-1.40%
Risk-free rate	1.0-1.5%	1.5-1.9%	1.0-2.7%	1.5-3.2%
Average risk-free rate	1.5%	1.9%	1.5-2.6%	1.9-3.2%
Expected term (in years)	5.1-6.7	5.1-6.5	5.1-6.7	5.1-6.5
Pre-vesting departure rate	0.4-3.9%	1.4-3.6%	0.4-3.9%	1.4-3.6%

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 separate 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, 2010, and changes during the nine months ended September 30, 2011:

	Shares (000's)	Weighted Average Grant-Date Fair Value
Non-vested shares at December 31, 2010	3,698	$18.33
Granted	1,466	19.44
Vested	(535)	21.31
Forfeited	(272)	23.03
Non-vested shares at September 30, 2011	4,357	$18.04

As of September 30, 2011, there was approximately $30 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 2 years.  Compensation cost related to time-based restricted stock and restricted stock units was approximately $23 million and $22 million for the nine months ended September 30, 2011 and 2010, respectively, and $7 million for the three months ended September 30, 2011 and 2010.

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, 2010, and changes during the nine months ended September 30, 2011:

	Shares (000's)	Weighted- Average Grant-Date Fair Value
Non-vested restricted stock and restricted stock units at December 31, 2010	6,072	$ 9.24
Granted
Vested	(637)	14.09
Forfeited and cancelled	(226)	8.67
Non-vested restricted stock and restricted stock units at September 30, 2011	5,209	$ 8.67

As of September 30, 2011, there was approximately $4 million of unrecognized compensation cost related to non-vested performance-based restricted stock and restricted stock units compensation arrangements granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 0.3 year.  Compensation cost related to performance-based restricted stock and restricted stock units was approximately $6 million and $12 million for the nine months ended September 30, 2011 and 2010, respectively, and $2 million and $3 million for the three months ended September 30, 2011 and 2010, respectively.

Worldwide Employee Stock Purchase Plan

In addition to the Stock Option Plans and Incentive Stock Plans, Corning offered a Worldwide Employee Share Purchase Plan (WESPP).  Under the WESPP, substantially all employees could elect to have up to 10% of their annual wages withheld to purchase our common stock.  The purchase price of the stock was 85% of the end-of-quarter closing market price.  Compensation cost related to the WESPP for all periods presented is immaterial.

On February 3, 2010, Corning's Board of Directors approved the recommendation to terminate on-going WESPP contributions effective March 31, 2010 and the WESPP terminated in May 2010.

Operating Segments

19.      Operating Segments

Our reportable operating 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 operating 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 operating 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 operating 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.  In the three and nine months ended September 30, 2011, the Telecommunications segment included a credit of $22 million from the reduction to a contingent liability associated with an acquisition recorded in the first quarter of 2011.

Net income	$	811	$	785	$	2,314	$	2,514

(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.  In the nine months ended September 30, 2010 equity earnings of affiliated companies, net of impairments, includes a credit of $21 million for our share of U.S. advanced energy manufacturing tax credits at Dow Corning Corporation.

(3) In the three and nine months ended September 30, 2011, Corning recorded a charge of $5 million and $15 million, respectively, to adjust the asbestos liability for the change in value of the components of the Amended PCC Plan.  In the three and nine months ended September 30, 2010, Corning recorded a charge of $6 million and a net credit of $41 million, respectively, primarily reflecting the change in the terms of the proposed asbestos settlement.

(4) In the three months ended September 30, 2011, Corning recorded a $41 million tax benefit from the filing of an amended 2006 U.S. Federal Tax return to claim foreign tax credits.  In the three months ended September 30, 2010, Corning recorded a loss of $30 million ($19 million after-tax) from the repurchase of $126 million principal amount of our 6.2% senior unsecured notes due March 15, 2016 and $100 million principal amount of our 5.9% senior unsecured notes due March 15, 2014.  In the nine months ended September 30, 2010, other corporate items included a tax charge of $56 million from the reversal of the deferred tax asset associated with a Medicare subsidy.

In the Display Technologies operating segment, assets increased from $9.1 billion at December 31, 2010 to $10.3 billion at September 30, 2011.  The increase is due primarily to an increase in investments due to earnings from Samsung Corning Precision and capital expenditures of approximately $800 million, offset somewhat by the reallocation of certain assets to the Specialty Materials segment.  In the Telecommunications operating segment, assets increased from $1.0 billion at December 31, 2010 to $1.2 billion at September 30, 2011.  The increase is due primarily to increases of certain working capital balances, the result of a small acquisition completed in the first quarter of 2011 and capital expenditures of approximately $100 million.  In the Specialty Materials operating segment, assets increased from $900 million at December 31, 2010 to $1.6 billion at September 30, 2011.  The increase is due primarily to the reallocation of certain assets from the Display Technologies operating segment and capital expenditures of approximately $300 million.

The sales of each of our reportable operating segments are concentrated across a relatively small number of customers.  In the third quarter of 2011, 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, four customers accounted for 76% of total segment sales.

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

·   In the Environmental Technologies segment, three customers accounted for 89% of total segment sales.

·   In the Specialty Materials segment, two customers accounted for 47% of total segment sales.

·   In the Life Sciences segment, two customers accounted for 51% of total segment sales.

In the nine months ended September 2011, 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, three customers accounted for 67% of total segment sales.

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

·   In the Environmental Technologies segment, three customers accounted for 85% of total segment sales.

·   In the Specialty Materials segment, two customers accounted for 40% of total segment sales.

·   In the Life Sciences segment, two customers accounted for 43% 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 use 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.

Fair Value Measurements

Fair Value Measurements

15.      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 September 30, 2011 and December 31, 2010, 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
	September 30,  2011	Quoted prices in active markets for identical assets (Level 1)	Significant other observable inputs (Level 2)	Significant unobservable inputs (Level 3)

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