Notes to Financial Statements
Significant Accounting Policies [Text Block]	1. Organization Corning Incorporated is a provider of high-performance glass for notebook computers, flat panel desktop monitors, LCD televisions, and other information display applications; carrier network and enterprise network products for the telecommunications industry; ceramic substrates for gasoline and diesel engines in automotive and heavy duty vehicle markets; laboratory products for the scientific community and specialized polymer products for biotechnology applications; advanced optical materials for the semiconductor industry and the scientific community; and other technologies. In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and subsidiary companies. Basis of Presentation and Principles of Consolidation Our consolidated financial statements were prepared in conformity with generally accepted accounting principles in the U.S. and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which Corning exercises control. The equity method of accounting is used for investments in affiliated companies that are not controlled by Corning and in which our interest is generally between 20% 50% 20% We use the cost method to account for our investments in companies that we do not control and for which we do not have the ability to exercise significant influence over operating and financial policies. In accordance with the cost method, these investments are recorded at cost or fair value, as appropriate. All material intercompany accounts, transactions and profits are eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current-year presentation. These reclassifications had no impact on our results of operations, financial position, or changes in shareholders’ equity. Samsung Corning Precision Materials Co., Ltd. (“Samsung Corning Precision Materials”) On January 15, 2014, 100% first 2014. first 2014. Refer to Note 8 Dow Corning Prior to May 31, 2016, May 31, 2016, December 2015. 50% 100% $4.8 Refer to Note 7 Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and related notes. Significant estimates and assumptions in these consolidated financial statements include estimates of fair value associated with revenue recognition, restructuring charges, goodwill and long-lived asset impairment tests, estimates of acquired assets and liabilities, estimates of fair value of investments, equity interests, environmental and legal liabilities, income taxes and deferred tax valuation allowances, assumptions used in calculating pension and other postretirement employee benefit expenses and the fair value of share-based compensation. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may Revenue Recognition Revenue for sales of goods is recognized when a firm sales agreement is in place, delivery has occurred and sales price is fixed or determinable and collection is reasonably assured. If customer acceptance of products is not reasonably assured, sales are recorded only upon formal customer acceptance. Sales of goods typically do not include multiple product and/or service elements. At the time revenue is recognized, allowances are recorded, with the related reduction to revenue, for estimated product returns, allowances and price discounts based upon historical experience and related terms of customer arrangements. Where we have offered product warranties, we also establish liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liabilities are adjusted when experience indicates the expected outcome will differ from initial estimates of the liability. In addition, Corning also has contractual arrangements with certain customers in which we recognize revenue on a completed contract basis. Revenues under the completed-contract method are recognized upon substantial completion, defined as acceptance by the customer and compliance with performance specifications as agreed upon in the contract. The Company acts as a principal under the contracts, and recognizes revenues with corresponding cost of revenues on a gross basis for the full amount of the contract. Research and Development Costs Research and development costs are charged to expense as incurred. Research and development costs totaled $637 2016, $638 2015 $701 2014. Foreign Currency Translation and Transactions The determination of the functional currency for Corning’s foreign subsidiaries is made based on the appropriate economic factors. For most foreign operations, the local currencies are generally considered to be the functional currencies. Corning’s most significant exception is our Taiwanese subsidiary, which uses the Japanese yen as its functional currency. For all transactions denominated in a currency other than a subsidiary’s functional currency, exchange rate gains and losses are included in income for the period in which the exchange rates changed. We recorded foreign currency transaction gains of $21 December 31, 2016, $22 $60 December 31, 2015 2014, Foreign subsidiary functional currency balance sheet accounts are translated at current exchange rates, and statement of operations accounts are translated at average exchange rates for the year. Translation gains and losses are recorded as a separate component of accumulated other comprehensive income in shareholders’ equity. The effects of remeasuring non-functional currency assets and liabilities into the functional currency are included in current earnings, except for those related to intra-entity foreign currency transactions of a long-term investment nature, which are recorded together with translation gains and losses in accumulated other comprehensive income (loss) in shareholders’ equity. Upon sale or substantially complete liquidation of an investment in a foreign entity, the amount of net translation gains or losses that have been accumulated in other comprehensive income attributable to that investment are reported as a gain or loss for the period in which the sale or liquidation occurs. Share-Based Compensation Corning’s share-based compensation programs include employee stock option grants, time-based restricted stock awards and time-based restricted stock units, as more fully described in Note 19 The cost of share-based compensation awards is equal to the fair value of the award at the date of grant and compensation expense is recognized for those awards earned over the vesting period. Corning estimates the fair value of share-based awards using a multiple-point Black-Scholes option valuation model, which incorporates assumptions including expected volatility, dividend yield, risk-free rate, expected term and departure rates. Cash and Cash Equivalents Cash equivalents consist of highly liquid investments that are readily convertible into cash. We consider securities with contractual maturities of three Supplemental disclosure of cash flow information follows (in millions): Years ended December 31, 2016 2015 2014 Non-cash transactions: Accruals for capital expenditures $ 381 $ 298 $ 358 Cash paid for interest and income taxes: Interest (1) $ 184 $ 178 $ 171 Income taxes, net of refunds received $ 293 $ 253 $ 577 (1) Included in this amount are approximately $23 $35 $40 2016, 2015 2014, Allowance for Doubtful Accounts The Company’s allowance for doubtful accounts is determined based on a variety of factors that affect the potential collectability of the related receivables, including length of time receivables are past due, customer credit ratings, financial stability of customers, specific one Environmental Liabilities The Company accrues for its environmental investigation, remediation, operating and maintenance costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. For environmental matters, the most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, current laws and regulations and prior remediation experience. For sites with multiple potential responsible parties, the Company considers its likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. Where no amount within a range of estimates is more likely to occur than another, the minimum amount is accrued. When future liabilities are determined to be reimbursable by insurance coverage, an accrual is recorded for the potential liability and a receivable is recorded related to the insurance reimbursement when reimbursement is virtually certain. The uncertain nature inherent in such remediation and the possibility that initial estimates may Inventories Inventories are stated at the lower of cost (first first Property, Plant and Equipment, Net of Accumulated Depreciation Land, buildings, and equipment, including precious metals, are recorded at cost. Depreciation is based on estimated useful lives of properties using the straight-line method. Except as described in Note 2 9 10 40 2 20 Included in the subcategory of equipment are the following types of assets (excluding precious metals): Asset type Range of useful life (in years) Computer hardware and software 3 to 7 Manufacturing equipment 2 to 15 Furniture and fixtures 5 to 10 Transportation equipment 3 to 20 Manufacturing equipment includes certain components of production equipment that are constructed of precious metals. These assets 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. We treat the physical loss of precious metals in the manufacturing and reclamation process as depletion and account for these losses as a period expense based on actual units lost. Precious metals are integral to many of our glass production processes. They are only acquired to support our operations and are not held for trading or other purposes. Goodwill and Other Intangible Assets Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill relates to and is assigned directly to a specific reporting unit. Reporting units are either operating segments or one may two three zero two zero The qualitative process includes an extensive review of expectations for the long-term growth of our businesses and forecasting future cash flows. If we are required to perform the two Other intangible assets include patents, trademarks, and other intangible assets acquired from an independent party. Such intangible assets have a definite life and are amortized on a straight-line basis over estimated useful lives ranging from 4 50 Impairment of Long-Lived Assets We review the recoverability of our long-lived assets, such as plant and equipment and intangible assets, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may 2 Employee Retirement Plans Corning offers employee retirement plans consisting of defined benefit pension plans covering certain domestic and international employees and postretirement plans that provide health care and life insurance benefits for eligible retirees and dependents. The costs and obligations related to these benefits reflect the Company’s assumptions related to general economic conditions (particularly interest rates), expected return on plan assets, rate of compensation increase for employees and health care trend rates. The cost of providing plan benefits depends on demographic assumptions including retirements, mortality, turnover and plan participation. Costs for our defined benefit pension plans consist of two 1) 2) 10% fourth Costs for our postretirement benefit plans consist of on-going costs recognized quarterly, and are comprised of service and interest costs, amortization of prior service costs and amortization of actuarial gains and losses. We recognize the actuarial gains and losses resulting from changes in actuarial assumptions for discount rates as a component of Shareholders’ Equity on our consolidated balance sheets on an annual basis and amortize them into our operating results over the average remaining service period of employees expected to receive benefits under the plans, to the extent such gains and losses are outside of the corridor. Refer to Note 13 Treasury Stock Shares of common stock repurchased by us are recorded at cost as treasury stock and result in a reduction of Shareholders’ Equity in the consolidated balance sheets. From time to time, treasury shares may Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to operating loss and tax credit carryforwards and for differences between the carrying amounts of existing assets and liabilities and their respective tax bases. The effective income tax rate reflects our assessment of the ultimate outcome of tax audits. In evaluating the tax benefits associated with our various tax filing positions, we record a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. Adjustments are made to our liability for unrecognized tax benefits in the period in which we determine the issue is effectively settled with the tax authorities, the statute of limitations expires for the return containing the tax position or when new information becomes available. Our liability for unrecognized tax benefits, including accrued penalties and interest, is included in other accrued liabilities and other long-term liabilities on our consolidated balance sheets and in income tax expense in our consolidated statements of income. Discrete events such as audit settlements or changes in tax laws are recognized in the period in which they occur. Valuation allowances are established when management is unable to conclude that it is more likely than not that some portion, or all, of the deferred tax asset will ultimately be realized. The Company is subject to income taxes in the United States and in numerous foreign jurisdictions. With minor exceptions, no provision is made for U.S. income taxes on the undistributed earnings of wholly-owned foreign subsidiaries because substantially all such earnings are indefinitely reinvested in those companies. Provision for the tax consequences of distributions, if any, from consolidated foreign subsidiaries is recorded in the year in which the earnings are no longer indefinitely reinvested in those subsidiaries. Equity Method Investments Our equity method investments are reviewed for impairment on a periodic basis or if an event occurs or circumstances change that indicate the carrying amount may ● Absence of our ability to recover the carrying amount; ● Inability of the equity affiliate to sustain an earnings capacity which would justify the carrying amount of the investment; and ● Significant litigation, bankruptcy or other events that could impact recoverability. For an equity investment with impairment indicators, we measure fair value on the basis of discounted cash flows or other appropriate valuation methods, depending on the nature of the company involved. If it is probable that we will not recover the carrying amount of our investment, the impairment is considered other-than-temporary and recorded in earnings, and the equity investment balance is reduced to its fair value accordingly. We require our material equity method affiliates to provide audited financial statements. Consequently, adjustments for asset recoverability are included in equity earnings. We also utilize these financial statements in our recoverability assessment. Fair Value of Financial Instruments 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. Derivative Instruments We participate in a variety of foreign exchange forward contracts and foreign exchange option contracts entered into in connection with the management of our exposure to fluctuations in foreign exchange rates. We utilize interest rate swaps to reduce the risk of changes in a benchmark interest rate from the probable forecasted issuance of debt and to swap fixed rate interest payments into floating rate interest payments. These financial exposures are managed in accordance with corporate policies and procedures. All derivatives are recorded at fair value on the balance sheet. Changes in the fair value of derivatives designated as cash flow hedges and hedges of net investments in foreign operations are not recognized in current operating results but are recorded in accumulated other comprehensive income. Amounts related to cash flow hedges are reclassified from accumulated other comprehensive income when the underlying hedged item impacts earnings. This reclassification is recorded in the same line item of the consolidated statements of income as where the effects of the hedged item are recorded, typically sales, cost of sales or other (expense) income, net. Changes in the fair value of derivatives not designated as hedging instruments are recorded in the Consolidated Statements of Income in the Translated earnings contract (loss) gain, net and the Other (expense) income, net lines .

Company expects to recognize $6 2017 $1 $3 2017. Corning uses a hypothetical yield curve and associated spot rate curve to discount the plan’s projected benefit payments. Once the present value of projected benefit payments is calculated, the suggested discount rate is equal to the level rate that results in the same present value. The yield curve is based on actual high-quality corporate bonds across the full maturity spectrum, which also includes private placements as well as Eurobonds that are denominated in U.S. currency. The curve is developed from yields on approximately 350 375 four 10% 40% Mortality is one seven December 31, 2014, 2000 October 27, 2014, 2000. fourth 2014, 2014 2D Prior to the December 31, 2015 25 Beginning with the December 31, 2015 Moving to a more granular approach has a limited impact on the determination of the respective benefit obligations. The only impacts will be as a result of the elimination of the rounding of the discount rate that occurred in the traditional approach and the use of specific cash flows for Corning’s non-qualified pension plans, while separately applying the yield curve to each separate OPEB plan instead of aggregating the OPEB plan cash flows. This change will result in a decrease in the interest cost and service cost components of net periodic pension and OPEB costs. For the year ended December 31, 2017, $23 $5 This change is a change in accounting estimate and therefore applied prospectively (beginning with the next measurement date of December 31, 2015).

We based these rates on asset/liability forecast modeling, which is based on our current asset allocation, the return and standard deviation for each asset class, current market conditions and transitions from current conditions to long-term returns. The Company’s overall investment strategy is to obtain sufficient return to offset or exceed inflation and provide adequate liquidity to meet the benefit obligations of the pension plan.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	15. Corning is exposed to interest rate and foreign currency risks due to the movement of these 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, South Korean won, New Taiwan dollar, Chinese yuan, and the euro. We seek to mitigate the impact of exchange rate movements in our income statement by using over-the-counter (OTC) derivative instruments including foreign exchange forward and option contracts. In general, these hedges expire coincident with the timing of the underlying foreign currency commitments and transactions. We are exposed to potential losses in the event of non-performance by our counterparties to these derivative contracts. However, we minimize this risk by maintaining a diverse group of highly-rated major international financial institutions. We do not expect to record any losses as a result of such counterparty default. Neither we nor our counterparties are required to post collateral for these financial instruments. The Company qualified for and elected the end-user exception to the mandatory swap clearing requirement of the Dodd-Frank Act. Cash Flow Hedges Our cash flow hedging activities utilize OTC foreign exchange forward contracts and options to reduce the risk that movements in exchange rates will adversely affect the net cash flows resulting from the sale of products to foreign customers and purchases from foreign suppliers. Our cash flow hedging activity also uses interest rate swaps to reduce the risk of increases in benchmark interest rates on the probable issuance of debt and associated interest payments.

The analysis excludes the impact of credit risk from the assessment of hedge effectiveness. The amount recorded in current period earnings in the other (expense) income, net component, relative to ineffectiveness, is nominal for the year ended December 31, 2016. Net gains and losses from fair value hedges and the effects of the corresponding hedged item are recorded on the same line item in the consolidated statements of income. Undesignated Hedges Corning also uses OTC foreign exchange forward and option contracts that are not designated as hedging instruments for accounting purposes. The undesignated hedges limit exposures to foreign functional currency fluctuations related to certain subsidiaries’ monetary assets, monetary liabilities and net earnings in foreign currencies. A significant portion of the Company’s non-U.S. revenues and expenses are denominated in Japanese yen, South Korean won, New Taiwan dollar, Chinese yuan and euro. When these revenues and expenses are translated back to U.S. dollars, the Company is exposed to foreign exchange rate movements. To protect translated earnings against movements in these currencies, the Company has entered into a series of zero With a zero zero zero zero 2022 2017 December 31, 2016, zero $1 The Company extended its foreign exchange hedge program in 2016 2018 2022.

Significant Accounting Policies

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Basis of Presentation and Principles of Consolidation Our consolidated financial statements were prepared in conformity with generally accepted accounting principles in the U.S. and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which Corning exercises control. The equity method of accounting is used for investments in affiliated companies that are not controlled by Corning and in which our interest is generally between 20% 50% 20% We use the cost method to account for our investments in companies that we do not control and for which we do not have the ability to exercise significant influence over operating and financial policies. In accordance with the cost method, these investments are recorded at cost or fair value, as appropriate. All material intercompany accounts, transactions and profits are eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current-year presentation. These reclassifications had no impact on our results of operations, financial position, or changes in shareholders’ equity.
Business Combinations Policy [Policy Text Block]	Samsung Corning Precision Materials Co., Ltd. (“Samsung Corning Precision Materials”) On January 15, 2014, 100% first 2014. first 2014. Refer to Note 8 Dow Corning Prior to May 31, 2016, May 31, 2016, December 2015. 50% 100% $4.8 Refer to Note 7
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and related notes. Significant estimates and assumptions in these consolidated financial statements include estimates of fair value associated with revenue recognition, restructuring charges, goodwill and long-lived asset impairment tests, estimates of acquired assets and liabilities, estimates of fair value of investments, equity interests, environmental and legal liabilities, income taxes and deferred tax valuation allowances, assumptions used in calculating pension and other postretirement employee benefit expenses and the fair value of share-based compensation. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition Revenue for sales of goods is recognized when a firm sales agreement is in place, delivery has occurred and sales price is fixed or determinable and collection is reasonably assured. If customer acceptance of products is not reasonably assured, sales are recorded only upon formal customer acceptance. Sales of goods typically do not include multiple product and/or service elements. At the time revenue is recognized, allowances are recorded, with the related reduction to revenue, for estimated product returns, allowances and price discounts based upon historical experience and related terms of customer arrangements. Where we have offered product warranties, we also establish liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liabilities are adjusted when experience indicates the expected outcome will differ from initial estimates of the liability. In addition, Corning also has contractual arrangements with certain customers in which we recognize revenue on a completed contract basis. Revenues under the completed-contract method are recognized upon substantial completion, defined as acceptance by the customer and compliance with performance specifications as agreed upon in the contract. The Company acts as a principal under the contracts, and recognizes revenues with corresponding cost of revenues on a gross basis for the full amount of the contract.
Research, Development, and Computer Software, Policy [Policy Text Block]	Research and Development Costs Research and development costs are charged to expense as incurred. Research and development costs totaled $637 2016, $638 2015 $701 2014.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation and Transactions The determination of the functional currency for Corning’s foreign subsidiaries is made based on the appropriate economic factors. For most foreign operations, the local currencies are generally considered to be the functional currencies. Corning’s most significant exception is our Taiwanese subsidiary, which uses the Japanese yen as its functional currency. For all transactions denominated in a currency other than a subsidiary’s functional currency, exchange rate gains and losses are included in income for the period in which the exchange rates changed. We recorded foreign currency transaction gains of $21 December 31, 2016, $22 $60 December 31, 2015 2014, Foreign subsidiary functional currency balance sheet accounts are translated at current exchange rates, and statement of operations accounts are translated at average exchange rates for the year. Translation gains and losses are recorded as a separate component of accumulated other comprehensive income in shareholders’ equity. The effects of remeasuring non-functional currency assets and liabilities into the functional currency are included in current earnings, except for those related to intra-entity foreign currency transactions of a long-term investment nature, which are recorded together with translation gains and losses in accumulated other comprehensive income (loss) in shareholders’ equity. Upon sale or substantially complete liquidation of an investment in a foreign entity, the amount of net translation gains or losses that have been accumulated in other comprehensive income attributable to that investment are reported as a gain or loss for the period in which the sale or liquidation occurs.
Compensation Related Costs, Policy [Policy Text Block]	Share-Based Compensation Corning’s share-based compensation programs include employee stock option grants, time-based restricted stock awards and time-based restricted stock units, as more fully described in Note 19 The cost of share-based compensation awards is equal to the fair value of the award at the date of grant and compensation expense is recognized for those awards earned over the vesting period. Corning estimates the fair value of share-based awards using a multiple-point Black-Scholes option valuation model, which incorporates assumptions including expected volatility, dividend yield, risk-free rate, expected term and departure rates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash equivalents consist of highly liquid investments that are readily convertible into cash. We consider securities with contractual maturities of three Supplemental disclosure of cash flow information follows (in millions): Years ended December 31, 2016 2015 2014 Non-cash transactions: Accruals for capital expenditures $ 381 $ 298 $ 358 Cash paid for interest and income taxes: Interest (1) $ 184 $ 178 $ 171 Income taxes, net of refunds received $ 293 $ 253 $ 577 (1) Included in this amount are approximately $23 $35 $40 2016, 2015 2014,
Receivables, Policy [Policy Text Block]	Allowance for Doubtful Accounts The Company’s allowance for doubtful accounts is determined based on a variety of factors that affect the potential collectability of the related receivables, including length of time receivables are past due, customer credit ratings, financial stability of customers, specific one
Asset Retirement Obligations and Environmental Cost, Policy [Policy Text Block]	Environmental Liabilities The Company accrues for its environmental investigation, remediation, operating and maintenance costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. For environmental matters, the most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, current laws and regulations and prior remediation experience. For sites with multiple potential responsible parties, the Company considers its likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. Where no amount within a range of estimates is more likely to occur than another, the minimum amount is accrued. When future liabilities are determined to be reimbursable by insurance coverage, an accrual is recorded for the potential liability and a receivable is recorded related to the insurance reimbursement when reimbursement is virtually certain. The uncertain nature inherent in such remediation and the possibility that initial estimates may
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost (first first
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment, Net of Accumulated Depreciation Land, buildings, and equipment, including precious metals, are recorded at cost. Depreciation is based on estimated useful lives of properties using the straight-line method. Except as described in Note 2 9 10 40 2 20 Included in the subcategory of equipment are the following types of assets (excluding precious metals): Asset type Range of useful life (in years) Computer hardware and software 3 to 7 Manufacturing equipment 2 to 15 Furniture and fixtures 5 to 10 Transportation equipment 3 to 20 Manufacturing equipment includes certain components of production equipment that are constructed of precious metals. These assets 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. We treat the physical loss of precious metals in the manufacturing and reclamation process as depletion and account for these losses as a period expense based on actual units lost. Precious metals are integral to many of our glass production processes. They are only acquired to support our operations and are not held for trading or other purposes.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill relates to and is assigned directly to a specific reporting unit. Reporting units are either operating segments or one may two three zero two zero The qualitative process includes an extensive review of expectations for the long-term growth of our businesses and forecasting future cash flows. If we are required to perform the two Other intangible assets include patents, trademarks, and other intangible assets acquired from an independent party. Such intangible assets have a definite life and are amortized on a straight-line basis over estimated useful lives ranging from 4 50
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets We review the recoverability of our long-lived assets, such as plant and equipment and intangible assets, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may 2
Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]	Employee Retirement Plans Corning offers employee retirement plans consisting of defined benefit pension plans covering certain domestic and international employees and postretirement plans that provide health care and life insurance benefits for eligible retirees and dependents. The costs and obligations related to these benefits reflect the Company’s assumptions related to general economic conditions (particularly interest rates), expected return on plan assets, rate of compensation increase for employees and health care trend rates. The cost of providing plan benefits depends on demographic assumptions including retirements, mortality, turnover and plan participation. Costs for our defined benefit pension plans consist of two 1) 2) 10% fourth Costs for our postretirement benefit plans consist of on-going costs recognized quarterly, and are comprised of service and interest costs, amortization of prior service costs and amortization of actuarial gains and losses. We recognize the actuarial gains and losses resulting from changes in actuarial assumptions for discount rates as a component of Shareholders’ Equity on our consolidated balance sheets on an annual basis and amortize them into our operating results over the average remaining service period of employees expected to receive benefits under the plans, to the extent such gains and losses are outside of the corridor. Refer to Note 13
Treasury Stock [Policy Text Block]	Treasury Stock Shares of common stock repurchased by us are recorded at cost as treasury stock and result in a reduction of Shareholders’ Equity in the consolidated balance sheets. From time to time, treasury shares may
Income Tax, Policy [Policy Text Block]	Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to operating loss and tax credit carryforwards and for differences between the carrying amounts of existing assets and liabilities and their respective tax bases. The effective income tax rate reflects our assessment of the ultimate outcome of tax audits. In evaluating the tax benefits associated with our various tax filing positions, we record a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. Adjustments are made to our liability for unrecognized tax benefits in the period in which we determine the issue is effectively settled with the tax authorities, the statute of limitations expires for the return containing the tax position or when new information becomes available. Our liability for unrecognized tax benefits, including accrued penalties and interest, is included in other accrued liabilities and other long-term liabilities on our consolidated balance sheets and in income tax expense in our consolidated statements of income. Discrete events such as audit settlements or changes in tax laws are recognized in the period in which they occur. Valuation allowances are established when management is unable to conclude that it is more likely than not that some portion, or all, of the deferred tax asset will ultimately be realized. The Company is subject to income taxes in the United States and in numerous foreign jurisdictions. With minor exceptions, no provision is made for U.S. income taxes on the undistributed earnings of wholly-owned foreign subsidiaries because substantially all such earnings are indefinitely reinvested in those companies. Provision for the tax consequences of distributions, if any, from consolidated foreign subsidiaries is recorded in the year in which the earnings are no longer indefinitely reinvested in those subsidiaries.
Equity Method Investments, Policy [Policy Text Block]	Equity Method Investments Our equity method investments are reviewed for impairment on a periodic basis or if an event occurs or circumstances change that indicate the carrying amount may ● Absence of our ability to recover the carrying amount; ● Inability of the equity affiliate to sustain an earnings capacity which would justify the carrying amount of the investment; and ● Significant litigation, bankruptcy or other events that could impact recoverability. For an equity investment with impairment indicators, we measure fair value on the basis of discounted cash flows or other appropriate valuation methods, depending on the nature of the company involved. If it is probable that we will not recover the carrying amount of our investment, the impairment is considered other-than-temporary and recorded in earnings, and the equity investment balance is reduced to its fair value accordingly. We require our material equity method affiliates to provide audited financial statements. Consequently, adjustments for asset recoverability are included in equity earnings. We also utilize these financial statements in our recoverability assessment.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments 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.
Derivatives, Policy [Policy Text Block]	Derivative Instruments We participate in a variety of foreign exchange forward contracts and foreign exchange option contracts entered into in connection with the management of our exposure to fluctuations in foreign exchange rates. We utilize interest rate swaps to reduce the risk of changes in a benchmark interest rate from the probable forecasted issuance of debt and to swap fixed rate interest payments into floating rate interest payments. These financial exposures are managed in accordance with corporate policies and procedures. All derivatives are recorded at fair value on the balance sheet. Changes in the fair value of derivatives designated as cash flow hedges and hedges of net investments in foreign operations are not recognized in current operating results but are recorded in accumulated other comprehensive income. Amounts related to cash flow hedges are reclassified from accumulated other comprehensive income when the underlying hedged item impacts earnings. This reclassification is recorded in the same line item of the consolidated statements of income as where the effects of the hedged item are recorded, typically sales, cost of sales or other (expense) income, net. Changes in the fair value of derivatives not designated as hedging instruments are recorded in the Consolidated Statements of Income in the Translated earnings contract (loss) gain, net and the Other (expense) income, net lines .
