CORNING INCORPORATED AND SUBSIDIARY COMPANIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Significant Accounting Policies

Basis of Presentation

In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and its 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. Generally Accepted Accounting Principles (“GAAP”) for interim financial information. Certain information and note disclosures normally included in financial statements prepared in accordance with 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, 2018 (“2018 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.

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.

Leases

Corning leases certain real estate, vehicles, and equipment from third parties. On January 1, 2019 we adopted the new leasing standard. Corning classifies leases as either financing or operating. Operating leases are included in other assets with the corresponding liability in other accrued liabilities and other liabilities on our consolidated balance sheets. Finance leases are included in property, plant and equipment with the corresponding liability in the current portion and long-term debt line items on our consolidated balance sheets. Leases where we are the lessor are not significant.

Lease expense is recognized on a straight-line basis over the lease term for operating leases. Financing leases are recognized on the effective interest method for interest expense and straight-line method for asset amortization. Renewals and terminations are included in the calculation of the Right of Use (“ROU”) assets and lease liabilities when considered to be reasonably certain to be exercised. When the implicit rate is unknown, we use our incremental borrowing rate based on commencement date in determining the present value of lease payments.

Our leases do not include residual value guarantees. We are not the primary beneficiary in or have other forms of variable interests with the lessor of the leased assets. The impact to the balance sheet for operating leases is a gross-up for the addition of ROU assets and liabilities relating to the operating leases in the amount of $449 million at adoption. The impact to the balance sheet for financing leases was not material.

Corning has elected the following practical expedients and accounting policy elections to apply the new lease accounting standard at its effective date as of January 1, 2019:

Leases of less than 12 months in duration to be recorded as expense only;

Account for lease and non-lease components of a contract as a single lease component; and

Comparative reporting of prior periods under ASC 840 not restated due to modified retrospective implementation.

At adoption, Corning recorded a nominal cumulative-effect adjustment to beginning retained earnings.

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

Revenue

One of Corning’s equity affiliates adopted the new revenue standard on January 1, 2019.  The impact of adopting the new standard to Corning’s financial statements was a net reduction of $186 million to 2019 beginning retained earnings. Timing of revenue recognition for certain open performance obligations as measured at January 1, 2019 under the new standard was approximately $239 million with offsetting deferred tax impacts of $53 million.

Income Taxes

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, which allows for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. We have adopted this new standard effective January 1, 2019. The impact of the new standard resulted in a reclassification of $53 million from accumulated other comprehensive income (“AOCI”) to beginning retained earnings.

Other Accounting Standards

No other accounting standards newly issued or adopted as of June 30, 2019, had a material impact on Corning’s financial statements or disclosures.

2. Revenue

Revenue Disaggregation Table

The following table shows revenues by major product categories, similar to our reportable segment disclosure. Within each product category, contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar. The commercial markets and selling channels are also similar. Except for an inconsequential amount of revenue for Telecommunications products, our product category revenues are recognized at point in time when control transfers to the customer.

Revenues by product category are as follows (in millions):

	Three Months Ended				Six Months Ended

Contract Assets and Liabilities

Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of Corning’s revenue recognition process. Most of Corning’s cost of fulfillment as a manufacturer of products is classified as inventory, fixed assets and intangible assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of our products and their respective manufacturing processes.

Contract liabilities include deferred revenues, other advanced payments and customer deposits. Deferred revenue and other advanced payments are not significant to our operations and are classified as part of other current liabilities in our financial statements. Customer deposits are predominately related to Display products and are classified as part of other current liabilities and other long-term liabilities as appropriate and are disclosed below.

We treat shipping and handling fees as a fulfillment cost and not as a separate performance obligation under the terms of our revenue contracts due to the perfunctory nature of the shipping and handling obligations.

Customer Deposits

As of June 30, 2019 and December 31, 2018, Corning had customer deposits of approximately $0.9 billion and $1.0 billion, respectively. The majority of these represent non-refundable cash deposits for customers to secure rights to an amount of glass produced by Corning under long-term supply agreements. The duration of these long-term supply agreements ranges up to 10 years. As glass is shipped to customers, Corning will recognize revenue and issue credit memoranda to reduce the amount of the customer deposit liability, which are applied against customer receivables resulting from the sale of glass. In the six months ended June 30, 2019, a credit memorandum of $37 million was issued; no such memorandums were issued in 2018. As of June 30, 2019 and December 31, 2018, $886 million and $922 million were recorded as other long-term liabilities, respectively. The remaining $42 million and $54 million, respectively, were classified as other current liabilities.

3. Commitments, Contingencies and Guarantees

Corning is a defendant in various lawsuits and is subject to various claims that arise in the normal course of business, the most significant of which are summarized below. 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.

Asbestos Claims

Corning and PPG Industries, Inc. each owned 50% of the capital stock of Pittsburgh Corning Corporation (“PCC”). PCC filed for Chapter 11 reorganization in 2000, and the Modified Third Amended Plan of Reorganization for PCC (the “Plan”) became effective in April 2016. At December 31, 2016, the Company’s liability under the Plan was $290 million, which is required to be paid through a series of fixed payments that began in the second quarter of 2017. Payments of $50 million and $35 million were made in June 2019 and June 2018, respectively. The total amount of remaining payments due in years 2020 through 2023 is $135 million, of which $35 million will be paid in the second quarter of 2020 and is classified as a current liability. The remaining $100 million is classified as a non-current liability.

Non-PCC Asbestos Claims

Corning is a defendant in certain cases alleging injuries from asbestos unrelated to PCC (the “non-PCC asbestos claims”) which had been stayed pending the confirmation of the Plan. The stay was lifted on August 25, 2016. At June 30, 2019 and December 31, 2018, the amount of the reserve for these non-PCC asbestos claims was estimated to be $145 million and $146 million, respectively. The reserve balance as of June 30, 2019 represents the undiscounted projection of claims and related legal fees for the estimated life of the litigation.

Dow Corning Chapter 11 Related Matters

Until June 1, 2016, Corning and The Dow Chemical Company (“Dow”) each owned 50% of the common stock of Dow Corning Corporation (“Dow Corning”). On May 31, 2016, Corning and Dow realigned their ownership interest in Dow Corning. Corning retained its indirect ownership interest in the Hemlock Semiconductor Group (“HSG”) and formed a new entity which had been capitalized by Dow Corning with $4.8 billion. Following the realignment, Corning no longer owned any interest in Dow Corning. With the realignment, Corning agreed to indemnify Dow Corning for 50% of Dow Corning’s non-ordinary course, pre-closing liabilities to the extent such liabilities exceed the amounts reserved for them by Dow Corning as of May 31, 2016, including two legacy Dow Corning matters: the Dow Corning Breast Implant Litigation, and the Dow Corning Bankruptcy Pendency Interest Claims.

11

Dow Corning Breast Implant Litigation

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 as shareholders in exchange for contributions to the Plan.

Under the terms of the Plan, Dow Corning has established and funded a Settlement Trust and a Litigation Facility, referred to above, to provide a means for tort claimants to settle or litigate their claims. Inclusive of insurance, Dow Corning has paid approximately $1.8 billion to the Settlement Trust. As of May 31, 2016, Dow Corning had recorded a reserve for breast implant litigation of $290 million. In the event Dow Corning’s total liability for these claims exceeds such amount, Corning may be required to indemnify Dow Corning for up to 50% of the excess liability, subject to certain conditions and limits. At June 30, 2019, Dow Corning had recorded a reserve for breast implant litigation of $263 million.

Dow Corning Bankruptcy Pendency Interest Claims

As a separate matter arising from the bankruptcy proceedings, Dow Corning is defending claims asserted by commercial creditors who claim additional compounded interest at default and state statutory judgment rates as well as attorneys’ fees and other enforcement costs, during the period from May 1995 through June 2004. As of May 31, 2016, Dow Corning had recorded a reserve for these claims of $107 million. In the event Dow Corning’s liability for these claims exceeds such amount, Corning may be required to indemnify Dow Corning for up to 50% of the excess liability, subject to certain conditions and limits. As of June 30, 2019, Dow Corning had recorded a reserve for these claims of $84 million.

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 15 active hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At June 30, 2019 and December 31, 2018, Corning had accrued approximately $26 million and $30 million, respectively, for the undiscounted 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. Leases

We have operating and finance leases for real estate, vehicles, and equipment.

We incurred lease expense in the amount of $38 million and $80 million for the three and six months ended June 30, 2019. Operating and Financing lease costs were $34 million and $4 million, and $71 million and $9 million, respectively, for the three and six months ended June 30, 2019. Short-term rental expense, for agreements less than one year in duration, is immaterial. For the three and six months ended June 30, 2019, financing lease cost was comprised of expenses for depreciation of right-of-use assets and Interest on lease liabilities in the amounts of $2 million and $4 million, and $2 million and $5 million, respectively.

Cash paid for amounts included in the measurement of lease liabilities totaled $26 million and $55 million for the three and six months ended June 30, 2019. Operating cash outflows from operating and financing leases were $22 million and $48 million, and $2 million and $5 million, respectively. Financing cash outflows from finance leases were nominal.

As of June 30, 2019, we have additional operating leases, primarily for new production facilities and equipment, that have not yet commenced of approximately $450 million on an undiscounted basis. These operating leases will commence between fiscal year 2019 and fiscal year 2020 with lease terms of 10 years to 25 years.

5. Income Taxes

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

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

Effective tax rate		57.4%		14.6%		25.3%		62.7%

‎

For the three and six months ended June 30, 2019, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional net tax expense of $86 million driven by changes to our tax reserves, rate differences on income (loss) of consolidated foreign companies, estimated impact of base erosion and anti-deferral tax (“BEAT”) offset by the expected benefits related to foreign derived intangible income (“FDII”) and the release of foreign valuation allowances on deferred tax assets.

For the three months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to a reduction in the estimated impact of BEAT attributable to year-to-date losses from foreign exchange and translated earnings contracts, additional tax amounts related to global intangible low-taxed income (“GILTI”) and a benefit from the release of a foreign valuation allowance on deferred tax assets.

For the six months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional tax expense of $172 million related to a preliminary agreement with the Internal Revenue Service (“IRS”) to settle the income tax audit for the years 2013 and 2014, additional tax amounts related to GILTI and benefits from the release of a foreign valuation allowance on deferred tax assets. The company expects to make a payment before the end of the year of approximately $40 million for the 2013-2014 tax audit settlements with the IRS. As of June 30, 2019, the company is not expecting any significant movements in the uncertain tax benefits in the next twelve months.

6. Earnings per Common Share

Long-term operating leases (Note 4)		452
Other non-current liabilities		629		887
Other liabilities	$	3,910	$	3,652

(1)The negative carrying value resulted from a one-time charge of $239 million to this entity in 2019 due to the adoption of the new revenue standard. This charge was offset by deferred tax impacts of $53 million. The charge relates to timing of revenue recognition for open performance obligations as measured at January 1, 2019. Most of these performance obligations are expected to be recognized within the next twelve months and the negative carrying value has been reduced by current period income.

10. Hedging Activities

Cash Flow Hedges

Our cash flow hedging activities utilize over-the-counter (“OTC”) foreign exchange forward contracts to reduce the risk that movements in exchange rates will adversely affect the net cash flows resulting from the sale of products to customers and purchases from suppliers. The total gross notional value for foreign currency cash flow hedges are $1.6 billion and $0.4 billion at June 30, 2019 and December 31, 2018, respectively. The majority of our foreign exchange forward contracts hedge a portion of the Company’s exposure to the Japanese yen denominated sales with maturities spanning the years 2020-2023 and with gross notional values of $1.2 billion at June 30, 2019. Corning defers gains and losses related to the cash flow hedges into accumulated other comprehensive loss on the consolidated balance sheets until the hedged item impacts earnings. At June 30, 2019, the amount expected to be reclassified into earnings within the next 12 months is a pre-tax net gain of $11 million.

The effect of cash flow hedges on Corning’s consolidated statements of income and other comprehensive income (loss) is not material for the three and six months ended June 30, 2019 and 2018.

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.

The table below includes a total gross notional value for translated earnings contracts of $13.5 billion and $13.6 billion at June 30, 2019 and December 31, 2018, respectively. These include gross notional value for average rate forwards of $11.0 billion for both periods and zero-cost collars and purchased put or call options of $2.5 billion and $2.6 billion at June 30, 2019 and December 31, 2018, respectively. The majority of our average rate forward contracts hedge a significant portion of the Company’s exposure to the Japanese yen with maturities spanning the years 2019-2023 and with gross notional values of $8.1 billion and $9.1 billion at June 30, 2019 and December 31, 2018, respectively. The average rate forward contracts also partially hedge the impacts of the South Korean won, Chinese yuan, euro, New Taiwan dollar and British pound translation on the Company’s projected net income. With respect to the zero-cost collars, the gross notional amount includes the value of both the put and call options. However, due to the nature of the zero-cost collars, only the put or the call option can be exercised at maturity.

The following tables summarize the notional amounts and respective fair values of Corning’s derivative financial instruments on a gross basis for June 30, 2019 and December 31, 2018 (in millions):

(1)The impact to income was primarily driven by yen-denominated hedges of translated earnings.

11. Fair Value Measurements

Fair value standards under 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.

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
			Quoted prices in	Significant other		Significant
			active markets for	observable		unobservable
	June 30,		identical assets	inputs		inputs

Current liabilities:
Other accrued liabilities (1)	$	67		$	67
Non-current liabilities:
Other liabilities (1)	$	345		$	345

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

(2)Other assets include one of the Company’s renewable energy derivative contracts that was measured using unobservable (Level 3) inputs, in the amount of $23 million.

(2)One of the Company’s equity securities was measured using unobservable (Level 3) inputs, in the amount of $16 million.

(3)Other liabilities include contingent consideration that was measured using unobservable (Level 3) inputs, in the amount of $20 million.

For the six months ended June 30, 2019, assets and liabilities that were measured using unobservable (Level 3) inputs resulted in unrealized gains recognized in earnings of $23 million for a renewable energy derivative contract and the reversal of a liability for contingent consideration of $20 million.

There were no significant financial assets and liabilities measured on a nonrecurring basis as of June 30, 2019 and December 31, 2018.

12. Shareholders’ Equity

Fixed Rate Cumulative Convertible Preferred Stock, Series A

Corning has 2,300 outstanding shares of Fixed Rate Cumulative Convertible Preferred Stock, Series A. The Preferred Stock is convertible at the option of the holder and the Company upon certain events, at a conversion rate of 50,000 shares of Corning’s common stock per one share of Preferred Stock, subject to certain anti-dilution provisions. As of June 30, 2019, the Preferred Stock has not been converted, and none of the anti-dilution provisions have been triggered.

Share Repurchases

In December 2016, Corning’s Board of Directors approved a $4 billion share repurchase program with no expiration date (the “2016 Repurchase Program”). On April 26, 2018, Corning’s Board of Directors approved a $2 billion share repurchase program with no expiration date (the “2018 Repurchase Program”).

In the three and six months ended June 30, 2019, the Company repurchased 4.8 and 12.6 million shares of common stock on the open market for approximately $151 million and $395 million, respectively, as part of its 2018 Repurchase Program.

In the three and six months ended June 30, 2018, the Company repurchased 24.6 million and 51.6 million shares of common stock on the open market for approximately $674 million and $1,488 million, respectively, as part of its 2016 Repurchase Program.

On July 17, 2019, Corning’s Board of Directors authorized $5 billion in share repurchases with no expiration date (the “2019 Repurchase Authorization”).

Accumulated Other Comprehensive Loss

In the three and six months ended June 30, 2019 and 2018, the change in accumulated other comprehensive loss was primarily related to the foreign currency translation adjustment.

(3)Tax effects are not significant.

13. Reportable Segments

Our reportable segments are as follows:

Display Technologies – manufactures glass substrates for flat panel liquid crystal displays and other high-performance display panels.

Optical Communications – manufactures carrier and enterprise network components for the telecommunications industry.

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.

Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.

Life Sciences – manufactures glass and plastic labware, equipment, media and reagents enabling workflow solutions for scientific applications.

All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This group is primarily comprised of the results of the pharmaceutical technologies business and new product lines and development projects, as well as certain corporate investments such as Eurokera and Keraglass equity affiliates.

We prepared the financial results for our reportable segments on a basis consistent with our internal disaggregation of financial information to assist our chief operating decision maker (“CODM”) in making internal operating decisions. The impact of changes in the Japanese yen, Korean won, Chinese yuan and new Taiwan dollar are excluded from segment sales and segment net income for the Display Technologies and Specialty Materials segments. The impact of changes in the euro, Chinese yuan and Japanese yen are excluded from segment sales and segment net income for our Environmental Technologies and Life Sciences segments. In January 2019, we began presenting results of the Environmental Technologies and Life Sciences segments on a constant-currency basis to mitigate the translation impact on these segments’ sales and net income. We have not recast prior periods as the impact of fluctuations in these currencies were not material as compared to prior periods. Certain income and expenses are included in the unallocated amounts in the reconciliation of reportable segment net income to consolidated net income. These include items that are not used by our CODM in evaluating the results of or in allocating resources to our segments and include the following items: the impact of our translated earnings contracts; acquisition-related costs; discrete tax items and other tax-related adjustments; certain litigation, regulatory and other legal matters; restructuring, impairment and other charges and credits; adjustments relating to acquisitions; and other non-recurring non-operational items. Although we exclude these amounts from segment results, they are included in reported consolidated results.

We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income. We have allocated certain common expenses among reportable segments differently than we would for stand-alone financial information. Segment net income may not be consistent with measures used by other companies.

OVERVIEW

Strategy and Capital Allocation Framework and recently introduced Strategy and Growth Framework

In October 2015, Corning announced a strategy and capital allocation framework (the “Framework”) that reflects the Company’s financial and operational strengths, as well as its ongoing commitment to increasing shareholder value.  The Framework outlined our leadership priorities and articulated the opportunities we saw across our businesses.  We designed the Framework to create significant value for shareholders by focusing our portfolio and leveraging our financial strength.  Under the Framework, we targeted generating $26 billion to $30 billion of cash through 2019, returning more than $12.5 billion to shareholders and investing $10 billion to extend our leadership positions and deliver growth.  As of June 30, 2019, Corning met its goal of returning more than $12.5 billion to shareholders and is on track to invest $11 billion for growth and extended leadership.

On June 14, 2019, Corning introduced its 2020-2023 Strategy and Growth Framework.  From 2020 to 2023, the company plans to invest $10 billion to $12 billion for growth and to return $8 billion to $10 billion to shareholders.

Corning’s Frameworks outline the company’s leadership priorities.  With both the nearly completed Strategy & Capital Allocation Framework and the new Strategy & Growth Framework, Corning plans to focus its portfolio and utilize its financial strength.  Our probability of success increases as we invest in our world-class capabilities.  Corning is concentrating approximately 80% of its research, development and engineering investment and capital spending on a cohesive set of three core technologies, four manufacturing and engineering platforms, and five market-access platforms.  This strategy allows us to quickly apply our talents and repurpose our assets as needed.

Summary of results for the three and six months ended June 30, 2019

Net sales for the three and six months ended June 30, 2019 were $2,940 million and $5,752 million, compared to $2,747 million and $5,247 million, respectively, during the same periods in 2018. Net sales in the Optical Communications segment increased $67 million and $245 million, respectively. Growth from multi-year hyperscale data center projects drove the increase in enterprise sales in both periods. Sales in carrier networks were down in the three months and up in the six months ended June 30, 2019. Increased sales of fiber were more than offset by a decrease in sales of North American fiber-to-the-home during the current quarter. The acquisition of 3M’s Communication Markets Division (“CMD”), which took place during the second quarter of 2018, also contributed to sales growth. Net sales in the Display Technologies segment increased by $68 million and $141 million, respectively, for the three and six months ended June 30, 2019, with volume increases in the mid-teens in percentage terms more than offsetting moderate price declines. The Specialty Materials segment net sales increased by $26 million and $57 million, respectively, resulting from higher sales of Gorilla Glass products in both periods and higher sales of Advanced Optics products contributing to year-to-date results. Net sales for Environmental Technologies increased $49 million and $89 million, respectively, driven by sales growth of gas particulate filters and heavy-duty diesel products. Life Sciences sales increased by $15 million and $26 million, respectively.

In the second quarter of 2019, we generated net income of $92 million, or $0.09 per share, compared to net income of $738 million, or $0.78 per share, for the same period in 2018. The decrease in net income of $646 million, was primarily driven by the following items (amounts presented after-tax):

Translated earnings losses in the current period of $84 million compared to gains in the prior period of $410 million;

The negative impact of discrete tax and other tax-related items in the amount of $90 million, largely driven by changes to our tax reserves and changes in our foreign valuation allowances for deferred tax assets;

Translation losses on Japanese yen-denominated debt in the current period compared to gains in the prior period resulting in $57 million of negative change; and

Higher costs of $33 million, primarily accelerated depreciation, within the Display Technologies segment.

The decreases in net income outlined above were offset by higher net income across all operating segments of $62 million driven by higher sales.

Diluted earnings per share decreased by $0.69 per share when compared to the second quarter of 2018, driven by the decrease in net income described, offset by the repurchase of 35.8 million shares of common stock over the last twelve months.

In the first half of 2019, we generated net income of $591 million, or $0.65 per share, compared to a net income of $149 million, or $0.12 per share, for the same period in 2018. The increase in net income of $442 million, was primarily driven by the following items (amounts presented after-tax):

Higher net income across all operating segments of $130 million driven by higher sales;

An increase of $181 million in translated earnings contract gains;

The positive impact of discrete tax and other tax-related items in the amount of $126 million, largely driven by the absence of a $172 million IRS audit settlement recorded in the first quarter of 2018 offset by changes to our tax reserves and a release of foreign valuation allowances on deferred tax assets; and

The absence of a $103 million charge related to legal matters, including a ruling in an intellectual property lawsuit and developments in civil litigation matters recorded in the first quarter of 2018.

The increases in net income outlined above were offset by other net charges and credits of $20 million, primarily driven by accelerated depreciation within the Display Technologies segment and other corporate charges.

Diluted earnings per share increased by $0.53 per share when compared to the first half of 2018, driven by the increase in net income described above, offset by the repurchase of 35.8 million shares of common stock over the last twelve months.

The translation impact of fluctuations in foreign currency exchange rates, including the impact of hedges realized in the current quarter, did not materially impact Corning’s consolidated net income in the three and six months ended June 30, 2019 when compared to the same periods in 2018.

2019 Corporate Outlook

We believe 2019 will be another year of strong growth and investment, consistent with our Strategy and Capital Allocation Framework and recently introduced Strategy and Growth Framework. In our Display Technologies segment, we expect full year 2019 price declines to improve further to a low-to mid-single digit percentage. We anticipate Corning’s display glass volume will grow by high-single digits driven by television screen size growth and the ramp of our Gen 10.5 facility in Hefei, China. In the Optical Communications segment, we expect sales to increase by a low-to-mid-single digit percentage, including the impact of a full year of sales from the acquisition of CMD. We expect growth in the Specialty Materials segment, the rate of which will depend on the adoption of our innovations. We expect low-teen percentage growth in our Environmental Technologies segment. We anticipate a mid-single digit percentage growth in sales for the Life Sciences segment.

For the three months ended June 30, 2019, net sales of operating segments increased by $227 million, or 8%, when compared to the same period in 2018. The primary sales drivers by segment were as follows:

Display Technologies net sales increased $68 million compared to the prior year, with the increase in glass volume in the mid-teens in percentage terms more than offsetting moderate price declines;

An increase of $67 million in the Optical Communications segment, due to higher sales of enterprise network products, up $83 million, offset by a sales decrease of $16 million for carrier products. These results include the impact of sales from the acquisition of CMD;

An increase of $26 million in the Specialty Materials segment, primarily driven by higher sales of Gorilla Glass;

An increase of $49 million in the Environmental Technologies segment, driven primarily by sales growth of gas particulate filters and heavy-duty diesel products; and

An increase of $15 million in the Life Sciences segment.

Movements in foreign exchange rates decreased Corning’s consolidated net sales in the amount of $34 million in the three months ended June 30, 2019, when compared to the prior year.

For the six months ended June 30, 2019, net sales of operating segments increased by $564 million, or 11%, when compared to the same period in 2018. The primary sales drivers by segment were as follows:

Display Technologies net sales increased $141 million compared to the prior year, with the increase in glass volume in the mid-teens in percentage terms more than offsetting moderate price declines;

An increase of $245 million in the Optical Communications segment, due to higher sales of enterprise and carrier network products, up $157 million and $88 million, respectively, including the impact of sales from the acquisition of CMD;

An increase of $57 million in the Specialty Materials segment, driven by higher sales of Gorilla Glass and Advanced Optics products;

An increase of $89 million in the Environmental Technologies segment, driven primarily by sales growth of gas particulate filters and heavy-duty diesel products; and

An increase of $26 million in the Life Sciences segment.

Movements in foreign exchange rates decreased Corning’s consolidated net sales in the amount of $59 million in the six months ended June 30, 2019, when compared to the prior year.

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

In the three and six months ended June 30, 2019, gross margin decreased by $7 million and 1% and increased by $137 million or 7%, respectively. Gross margin was negatively impacted by $75 million and $52 million, respectively, primarily due to increased accelerated depreciation for the Display Technologies segment and capacity expansion in China.

Selling, General and Administrative Expenses

When compared to the second quarter of 2018, selling, general and administrative expenses were similar in the three months ended June 30, 2019.

When compared to the first half of 2018, selling, general and administrative expenses decreased by $98 million, or 11%, in the six months ended June 30, 2019. The decrease was due to the absence of a $132 million charge related to legal matters in 2018, including a ruling in an intellectual property lawsuit and developments in civil litigation matters; partially offset by an increase of $39 million in the Optical Communications segment, driven largely by the acquisition of CMD in June 2018.

Selling, general and administrative expenses remained constant as a percentage of sales at 14% for the three and six months ended June 30, 2019.

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; and depreciation and amortization, utilities and rent for administrative facilities.

Research, Development and Engineering Expenses

For the three and six months ended June 30, 2019, research, development and engineering expenses increased by $6 million, or 2%, and $14 million, or 3%, respectively, when compared to the same periods last year, driven by higher costs associated with new product launches and our emerging businesses. As a percentage of sales, these expenses decreased by 1% and remained constant, respectively, when compared to the same periods last year.

Equity in Earnings of Affiliated Companies

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

	Three months ended				Six months ended

All other		(2)				(2)
Total equity earnings	$	33	$	31	$	58	$	70

Equity in earnings of affiliated companies for the six months ended June 30, 2019 decreased by $12 million, driven primarily by the absence of a gain recorded in the first quarter of 2018 resulting from a legal settlement.

Translated earnings contract (loss) gain, net

Included in the line item Translated earnings contract (loss) gain, net, is the impact of foreign currency hedges which hedge our translation exposure arising from movements in the Japanese yen, South Korean won, new Taiwan dollar, euro, Chinese yuan and British pound and its impact on our net earnings. The following table provides detailed information on the impact of our translated earnings contract gains and losses:

The gross notional value outstanding on our translated earnings contracts at June 30, 2019 and December 31, 2018 were as follows (in billions):

	June 30,		December 31,
	2019		2018
Japanese yen-denominated hedges	$	10.6	$	11.6

Euro-denominated hedges		1.9		1.2
Other hedges		0.6		0.7
Total gross notional value ‎  outstanding	$	13.5	$	13.6

Income Before Income Taxes

The translation impact of fluctuations in foreign currency exchange rates, including the impact of hedges realized in the current quarter, did not materially impact Corning’s consolidated income before income taxes in the three and six months ended June 30, 2019 when compared to the same periods in 2018.

Provision for Income Taxes

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

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2019		2018		2019		2018
Provision for income taxes	$	(124)	$	(126)	$	(200)	$	(250)
Effective tax rate		57.4%		14.6%		25.3%		62.7%

For the three and six months ended June 30, 2019, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional net tax expense of $86 million driven by changes to our tax reserves, rate differences on income (loss) of consolidated foreign companies, estimated impact of base erosion and BEAT offset by the expected benefits related to FDII and the release of foreign valuation allowances on deferred tax assets.

For the three months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to a reduction in the estimated impact of BEAT attributable to year-to-date losses from foreign exchange and translated earnings contracts, additional tax amounts related to GILTI and a benefit from the release of a foreign valuation allowance on deferred tax assets.

For the six months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional tax expense of $172 million related to a preliminary agreement with the IRS to settle the income tax audit for the years 2013 and 2014, additional tax amounts related to GILTI and a benefit from the release of a foreign valuation allowance on deferred tax assets. The company expects to make a payment before the end of the year of approximately $40 million for the 2013-2014 tax audit settlements with the IRS. As of June 30, 2019, the company is not expecting any significant movements in the uncertain tax benefits in the next twelve months.

Comprehensive Income

For the three months ended June 30, 2019 comprehensive income decreased by $152 million when compared to the same period in 2018, due to lower net income of $646 million offset by $466 million of positive impacts from the change in foreign currency translation gains and losses, driven primarily by the Japanese yen and Korean won.

For the six months ended June 30, 2019 comprehensive income increased by $515 million when compared to the same period in 2018, primarily due to an increase in net income of $442 million and $92 million of positive impacts from the change in foreign currency translation gains and losses, driven primarily by the euro and the Chinese yuan. These impacts were partially offset by $53 million related to the adoption of the new standard for reclassification of stranded tax effects in AOCI.

Refer to Note 12 (Shareholders’ Equity) to the consolidated financial statements for additional information.

CORE PERFORMANCE MEASURES

In managing the Company and assessing our financial performance, we adjust certain measures provided by our consolidated financial statements to exclude specific items to report core performance measures. These items include gains and losses on our translated earnings contracts, acquisition-related costs, certain discrete tax items, restructuring and restructuring-related charges, certain litigation-related expenses, pension mark-to-market adjustments and other items which do not reflect on-going operating results of the Company or our equity affiliates. Corning utilizes constant-currency reporting for our Display Technologies and Specialty Materials segments for the Japanese yen, South Korean won, Chinese yuan and new Taiwan dollar currencies. Effective January 1, 2019, Corning also began using constant-currency reporting for our Environmental Technologies and Life Sciences segments for the euro, Japanese yen and Chinese yuan. The Company believes that the use of constant-currency reporting allows investors to understand our results without the volatility of currency fluctuations, and reflects the underlying economics of the translated earnings contracts used to mitigate the impact of changes in currency exchange rates on our earnings and cash flows. Corning also believes that reporting core performance measures provides investors greater transparency to the information used by our management team to make financial and operational decisions.

Core performance measures are not prepared in accordance with GAAP.  We believe investors should consider these non-GAAP measures in evaluating our results as they are more indicative of our core operating performance and how management evaluates our operational results and trends.  These measures are not, and should not be viewed as a substitute for, GAAP reporting measures.  With respect to the Company’s outlooks for future periods, it is not possible to provide reconciliations for these non-GAAP measures because the Company does not forecast foreign currency exchange rates or other items that do not reflect ongoing operations, nor does it forecast items that have not yet occurred or are out of the Company’s control.  As a result, the Company is unable to provide outlook information on a GAAP basis.

For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, please see “Reconciliation of Non-GAAP Measures” below.

Reconciliation of Non-GAAP Measures

We utilize certain financial measures and key performance indicators that are not calculated in accordance with GAAP to assess our financial and operating performance. A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the statement of income or statement of cash flows, or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure as calculated and presented in accordance with GAAP in the statement of income or statement of cash flows.

Core net sales, core equity in earnings of affiliated companies and core earnings are non-GAAP financial measures utilized by our management to analyze financial performance without the impact of items that are driven by general economic conditions and events that do not reflect the underlying fundamentals and trends in the Company’s operations.

The following tables reconcile our non-GAAP financial measures to their most directly comparable GAAP financial measure (amounts in millions except percentages and per share amounts):

‎

34

Items which we exclude from GAAP measures to report core performance measures are as follows:

(1)	Constant-currency adjustment:  Because a significant portion of segment revenues and expenses are denominated in currencies other than the US dollar, management believes it is important to understand the impact on core earnings of translating these currencies into U.S. dollars.  Our Display Technologies segment sales and net income are primarily denominated in Japanese yen, but also impacted by the Korean won, Chinese yuan, and new Taiwan dollar.  Beginning January 1, 2019, as our Environmental Technologies and Life Science segments sales and net income are impacted by the euro, Chinese yuan and Japanese yen, these segments will also be presented on a constant-currency basis.  We have not recast the prior periods for these two segments as the impact of fluctuations in these currencies are not material for prior periods.  Presenting results on a constant-currency basis mitigates the translation impact and allows management to evaluate performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts.  We establish constant-currency rates based on internally derived management estimates which are closely aligned with the currencies we have hedged.
	Constant-currency rates are as follows:
	Currency	Japanese yen	Korean won	Chinese yuan	New Taiwan dollar	Euro
	Rate	¥107	₩1,175	¥6.7	NT$31	€.81
(2)	Translation (gain) loss on Japanese yen-denominated debt: We have excluded the gain or loss on the translation of our yen-denominated debt to U.S. dollars.
(3)	Translated earnings contract (gain) loss: We have excluded the impact of the realized and unrealized gains and losses of our Japanese yen, euro, South Korean won, new Taiwan dollar and Chinese yuan-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our British pound-denominated foreign currency hedges related to translated earnings.
(4)	Acquisition-related costs: These expenses include intangible amortization, inventory valuation adjustments and external acquisition-related deal costs.
(5)	Discrete tax items and other tax-related adjustments: These include discrete period tax items such as changes in tax law, the impact of tax audits, changes in judgement about the realizability of certain deferred tax assets and other non-operational tax-related adjustments.
(6)	Litigation, regulatory and other legal matters: Includes amounts that reflect developments in commercial litigation, intellectual property disputes and other legal matters.
(7)	Restructuring, impairment and other charges and credits: This amount includes restructuring, impairment and other charges and credits, as well as other expenses which are not related to continuing operations and are not classified as restructuring expense.
(8)	Equity in earnings of affiliated companies: These adjustments relate to costs not related to continuing operations of our affiliated companies, such as restructuring, impairment, other charges and credits and settlements under “take-or-pay” contracts.
(9)	Pension mark-to-market adjustment: Defined benefit pension mark-to-market gains and losses, which arise from changes in actuarial assumptions and the difference between actual and expected returns on plan assets and discount rates.

REPORTABLE SEGMENTS

Our reportable segments are as follows:

Display Technologies – manufactures glass substrates primarily for flat panel displays.

Optical Communications – manufactures carrier and enterprise network components for the telecommunications industry.

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.

Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel emission control applications.

Life Sciences – manufactures glass and plastic labware, equipment, media and reagents enabling workflow solutions for scientific applications.

All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This group is primarily comprised of the results of the pharmaceutical technologies business and new product lines and development projects, as well as certain corporate investments such as Eurokera and Keraglass equity affiliates.

We prepared the financial results for our reportable segments on a basis consistent with our internal disaggregation of financial information to assist in making internal operating decisions. We use a segment tax rate of 21% when presenting segment information. The impact of changes in the Japanese yen, euro, Korean won, Chinese yuan and new Taiwan dollar are excluded from segment sales and segment net income for the Display Technologies, Specialty Materials, Environmental Technologies and Life Science segments. Certain corporate income and expenses are included in the unallocated amounts in the reconciliation of reportable segment net income to consolidated net income. These include items that are not used by our CODM in evaluating the results of, or in allocating resources to, our segments and include the following items: the impact of our translated earnings contracts; acquisition-related costs; discrete tax items and other tax-related adjustments; certain litigation, regulatory and other legal matters; restructuring, impairment and other charges and credits; adjustments relating to acquisitions; and other non-recurring non-operational items. Although we exclude these amounts from segment results, they are included in reported consolidated results.

We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income. We have allocated certain common expenses among reportable segments differently than we would for stand-alone financial information. Segment net income may not be consistent with measures used by other companies.

Display Technologies

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

	Three months ended				%	Six months ended				%
	June 30,				change	June 30,				change
	2019		2018		19 vs. 18	2019		2018		19 vs. 18
Segment net sales	$	848	$	780	9%	$	1,666	$	1,525	9%
Segment net income	$	213	$	192	11%	$	421	$	377	12%

Net sales in the Display Technologies segment increased by $68 million and $141 million in the three and six months ended June 30, 2019, respectively, with the increase in glass volume in the mid-teens in percentage terms more than offsetting moderate price declines.

Net income in the Display Technologies segment increased by $21 million and $44 million in the three and six months ended June 30, 2019, respectively, driven by the increase in sales outlined above.

Outlook:

For the third quarter of 2019, we expect display glass market volume to be consistent on a year-over-year basis, and our volume to grow faster than the market. Third-quarter display glass prices are expected to be consistent with second quarter.

Net sales in the Optical Communications segment increased by $67 million, or 7%, and $245 million, or 13%, respectively, for the three and six months ended June 30, 2019. Sales of enterprise network products increased by $83 million and $157 million, respectively, largely due to growth from multi-year hyperscale data center projects. Sales in carrier networks decreased by $16 million and increased by $88 million, respectively. Sales of fiber were more than offset by a decrease in sales of North American fiber-to-the-home during the current quarter. The acquisition of CMD, which took place during the second quarter of 2018, also contributed to sales growth for both periods.

Net income increased by $8 million, or 5%, and $41 million, or 16%, respectively, for the three and six months ended June 30, 2019. The increase was driven by the increase in sales, outlined above.

Outlook:

In the third quarter, Optical Communications sales are expected to decrease by low-single digits on a year-over-year basis.

All Other

All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This group is primarily comprised of the results of the pharmaceutical technologies business and new product lines and development projects, as well as certain corporate investments such as Eurokera and Keraglass equity affiliates.

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

	Three months ended				%	Six months ended				%

Segment net loss	$	(68)	$	(78)	13%	$	(140)	$	(152)	8%

Net sales of this segment increased by $2 million, or 4%, and $6 million, or 6% for the three and six months ended June 30, 2019 when compared to the same periods in 2018, driven primarily by an increase in sales in our emerging businesses. Net loss decreased by $10 million, or 13%, and $12 million, or 8%, primarily driven by the increase in sales.

CAPITAL RESOURCES AND LIQUIDITY

Financing and Capital Resources

There were no significant items that impacted Corning’s financing structure in the six months ended June 30, 2019.

In the second quarter of 2018, Corning issued ¥65.5 billion Japanese yen-denominated debt securities in tranches of 7, 10 and 12 years. The proceeds from these notes were received in Japanese yen and immediately converted to U.S. dollars on the date of issuance. The net proceeds received in U.S. dollars, after deducting offering expenses, was $596 million. Payments of principal and interest on the notes will be in Japanese yen, or should yen be unavailable due to circumstances beyond Corning’s control, a U.S. dollar equivalent.

Share Repurchase Program

In December 2016, Corning’s Board of Directors approved a $4 billion share repurchase program with no expiration date (the “2016 Repurchase Program”). On April 26, 2018, Corning’s Board of Directors approved a $2 billion share repurchase program with no expiration date (the “2018 Repurchase Program”).

Net cash used in investing activities	$	(1,034)	$	(1,755)

Net cash provided by operating activities decreased by $911 million in the six months ended June 30, 2019, when compared to the same period in the prior year. The change was primarily driven by fewer customer deposits and incentives received of $574 million, and negative changes in certain working capital items, most notably accounts payable and other liabilities of $219 million and accounts receivable of $160 million.

Net cash used in investing activities decreased by $721 million in the six months ended June 30, 2019 when compared to the same period last year, primarily resulting from the absence of acquisition costs in the current period. We acquired CMD in the second quarter of 2018 for a cash cost of $794 million.

Net cash used in financing activities in the six months ended June 30, 2019 decreased by $1.3 billion when compared to the same period last year, driven primarily by a decrease of $1.1 billion in share repurchases.

Management Assessment of Liquidity

We ended the first half of 2019 with approximately $1.2 billion of cash and cash equivalents. Our cash and cash equivalents are held in various locations throughout the world, with approximately 88% held outside of the United States, and are generally unrestricted. We utilize a variety of financing strategies to ensure that our worldwide cash is available in the locations in which it is needed.

Corning also has a commercial paper program pursuant to which we may issue short-term, unsecured commercial paper up to a maximum aggregate principal amount outstanding at any one time of $1.5 billion. Under this program, the Company may issue the paper from time to time and will use the proceeds for general corporate purposes. The Company’s Revolving Credit Agreement is available to support obligations under the commercial paper program, if needed. At December 31, 2018 Corning had no outstanding commercial paper. As of June 30, 2019, Corning had $446 million of outstanding commercial paper.

Other

We complete comprehensive reviews of our significant customers and their creditworthiness by analyzing their financial strength at least annually or more frequently for customers where we have identified a measure of increased risk. We closely monitor payments and developments which 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 2019 and beyond will be our operating cash flow, our existing balances of cash and cash equivalents and proceeds from any issuances of debt. We believe we have sufficient liquidity to fund operations, acquisitions, capital expenditures, scheduled debt repayments, dividend payments and share repurchase programs.

Our Revolving Credit Agreement includes affirmative and negative covenants with which we must comply, including a leverage (debt to capital ratio) financial covenant. The required leverage ratio is a maximum of 60%. At June 30, 2019, our leverage using this measure was approximately 33%. As of June 30, 2019, we were in compliance and no amounts were outstanding.

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, some of our debt instruments contain a cross default provision, whereby an uncured default of a specified amount on one debt obligation of the Company, also would be considered a default under the terms of another debt instrument. As of June 30, 2019, 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 decrease in our liquidity. In addition, other than items discussed, there are no known material trends, favorable or unfavorable, in our capital resources and no expected material changes in the mix and relative cost of such resources.

Off Balance Sheet Arrangements

There have been no material changes outside the ordinary course of business in our off-balance sheet arrangements as disclosed in our 2018 Form 10-K under the caption “Off Balance Sheet Arrangements.”

Contractual Obligations

There have been no material changes outside the ordinary course of business in the contractual obligations disclosed in our 2018 Form 10-K under the caption “Contractual Obligations.”

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements requires management to make estimates and assumptions that affect amounts reported therein. The estimates that require management’s most difficult, subjective or complex judgments are described in our 2018 Form 10-K and remain unchanged through the first six months of 2019. 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 and have a very long useful life. Precious metals are reviewed for impairment as part of our assessment of long-lived assets. This review considers all 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 manufacturing operations and are not held for trading or other purposes.

‎

40

At June 30, 2019 and December 31, 2018, the carrying value of precious metals was higher than the fair market value by $380 million and $719 million, respectively. These precious metals are utilized by the Display Technologies and Specialty Materials segments. Corning believes these precious metal assets to be recoverable due to the significant positive cash flow in both segments. The potential for impairment exists in the future if negative events significantly decrease the cash flow of these segments. Such events include, but are not limited to, a significant decrease in demand for products or a significant decrease in profitability in our Display Technologies or Specialty Materials segments.

NEW ACCOUNTING STANDARDS

Refer to Note 1 (Significant Accounting Policies) to the consolidated financial statements.

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 15 active hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At June 30, 2019 and December 31, 2018, Corning had accrued approximately $26 million and $30 million, respectively, for the undiscounted 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.

FORWARD-LOOKING STATEMENTS

The statements in this Quarterly Report on Form 10-Q, in reports subsequently filed by Corning with the SEC on Forms 8-K, and related comments by management that are not historical facts or information and contain words such as “will,” “believe,” “anticipate,” “expect,” “intend,” “plan,” “seek,” “see,” “would,” and “target” and similar expressions are forward-looking statements. Such statements relate to future events that by their nature address matters that are, to different degrees, uncertain. These forward-looking statements relate to, among other things, the company’s future operating performance, the company's share of new and existing markets, the company's revenue and earnings growth rates, the company’s ability to innovate and commercialize new products, and the company’s implementation of cost-reduction initiatives and measures to improve pricing, including the optimization of the company’s manufacturing capacity.

41

Although the company believes that these forward-looking statements are based upon reasonable assumptions regarding, among other things, current estimates and forecasts, general economic conditions, its knowledge of its business, and key performance indicators that impact the company, actual results could differ materially. The company does not undertake to update forward-looking statements. Some of the risks, uncertainties and other factors that could cause actual results to differ materially from those expressed in or implied by the forward-looking statements include, but are not limited to:

the effects of acquisitions, dispositions and other similar transactions;

global business, financial, economic and political conditions;

tariffs and import duties;

currency fluctuations between the U.S. dollar and other currencies, primarily the Japanese yen, new Taiwan dollar, euro, Chinese yuan and South Korean won;

product demand and industry capacity;

competitive products and pricing;

availability and costs of critical components and materials;

new product development and commercialization;

order activity and demand from major customers;

the amount and timing of our cash flows and earnings and other conditions, which may affect our ability to pay our quarterly dividend at the planned level or to repurchase shares at planned levels; 

possible disruption in commercial activities due to terrorist activity, cyber-attack, armed conflict, political or financial instability, natural disasters, or major health concerns;

loss of intellectual property due to theft, cyber-attack, or disruption to our information technology infrastructure;

unanticipated disruption to equipment, facilities, IT systems or operations;

effect of regulatory and legal developments;

ability to pace capital spending to anticipated levels of customer demand;

rate of technology change;

ability to enforce patents and protect intellectual property and trade secrets;

adverse litigation;

product and components performance issues;

retention of key personnel;

customer ability, most notably in the Display Technologies segment, to maintain profitable operations and obtain financing to fund ongoing operations and manufacturing expansions and pay receivables when due;

loss of significant customers;

changes in tax laws and regulations including the 2017 Tax Cuts and Jobs Act;

the impacts of audits by taxing authorities;

the potential impact of legislation, government regulations, and other government action and investigations; and

other risks detailed in Corning’s SEC filings.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures

As noted in our 2018 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 and how we mitigate that 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 2018 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision of and with the participation of Corning’s management, including our chief executive officer and chief financial officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), as of June 30, 2019, the end of the period covered by this report. Based on that evaluation, we have concluded that the Company’s disclosure controls and procedures were effective as of that date. 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.

An evaluation of our internal controls over financial reporting was also performed to determine whether any changes have occurred during the period covered by this Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The chief executive officer and chief financial officer concluded that there was no change in Corning’s internal control over financial reporting that materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

1. Significant Accounting Policies

Basis of Presentation

In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and its 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. Generally Accepted Accounting Principles (“GAAP”) for interim financial information. Certain information and note disclosures normally included in financial statements prepared in accordance with 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, 2018 (“2018 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.

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.

Leases

Corning leases certain real estate, vehicles, and equipment from third parties. On January 1, 2019 we adopted the new leasing standard. Corning classifies leases as either financing or operating. Operating leases are included in other assets with the corresponding liability in other accrued liabilities and other liabilities on our consolidated balance sheets. Finance leases are included in property, plant and equipment with the corresponding liability in the current portion and long-term debt line items on our consolidated balance sheets. Leases where we are the lessor are not significant.

Lease expense is recognized on a straight-line basis over the lease term for operating leases. Financing leases are recognized on the effective interest method for interest expense and straight-line method for asset amortization. Renewals and terminations are included in the calculation of the Right of Use (“ROU”) assets and lease liabilities when considered to be reasonably certain to be exercised. When the implicit rate is unknown, we use our incremental borrowing rate based on commencement date in determining the present value of lease payments.

Our leases do not include residual value guarantees. We are not the primary beneficiary in or have other forms of variable interests with the lessor of the leased assets. The impact to the balance sheet for operating leases is a gross-up for the addition of ROU assets and liabilities relating to the operating leases in the amount of $449 million at adoption. The impact to the balance sheet for financing leases was not material.

Corning has elected the following practical expedients and accounting policy elections to apply the new lease accounting standard at its effective date as of January 1, 2019:

Leases of less than 12 months in duration to be recorded as expense only;

Account for lease and non-lease components of a contract as a single lease component; and

Comparative reporting of prior periods under ASC 840 not restated due to modified retrospective implementation.

At adoption, Corning recorded a nominal cumulative-effect adjustment to beginning retained earnings.

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

‎

Revenue

One of Corning’s equity affiliates adopted the new revenue standard on January 1, 2019.  The impact of adopting the new standard to Corning’s financial statements was a net reduction of $186 million to 2019 beginning retained earnings. Timing of revenue recognition for certain open performance obligations as measured at January 1, 2019 under the new standard was approximately $239 million with offsetting deferred tax impacts of $53 million.

Income Taxes

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, which allows for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. We have adopted this new standard effective January 1, 2019. The impact of the new standard resulted in a reclassification of $53 million from accumulated other comprehensive income (“AOCI”) to beginning retained earnings.

Other Accounting Standards

No other accounting standards newly issued or adopted as of June 30, 2019, had a material impact on Corning’s financial statements or disclosures.

Revenue Disaggregation Table

The following table shows revenues by major product categories, similar to our reportable segment disclosure. Within each product category, contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar. The commercial markets and selling channels are also similar. Except for an inconsequential amount of revenue for Telecommunications products, our product category revenues are recognized at point in time when control transfers to the customer.

Revenues by product category are as follows (in millions):

‎

Contract Assets and Liabilities

Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of Corning’s revenue recognition process. Most of Corning’s cost of fulfillment as a manufacturer of products is classified as inventory, fixed assets and intangible assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of our products and their respective manufacturing processes.

Contract liabilities include deferred revenues, other advanced payments and customer deposits. Deferred revenue and other advanced payments are not significant to our operations and are classified as part of other current liabilities in our financial statements. Customer deposits are predominately related to Display products and are classified as part of other current liabilities and other long-term liabilities as appropriate and are disclosed below.

We treat shipping and handling fees as a fulfillment cost and not as a separate performance obligation under the terms of our revenue contracts due to the perfunctory nature of the shipping and handling obligations.

Customer Deposits

As of June 30, 2019 and December 31, 2018, Corning had customer deposits of approximately $0.9 billion and $1.0 billion, respectively. The majority of these represent non-refundable cash deposits for customers to secure rights to an amount of glass produced by Corning under long-term supply agreements. The duration of these long-term supply agreements ranges up to 10 years. As glass is shipped to customers, Corning will recognize revenue and issue credit memoranda to reduce the amount of the customer deposit liability, which are applied against customer receivables resulting from the sale of glass. In the six months ended June 30, 2019, a credit memorandum of $37 million was issued; no such memorandums were issued in 2018. As of June 30, 2019 and December 31, 2018, $886 million and $922 million were recorded as other long-term liabilities, respectively. The remaining $42 million and $54 million, respectively, were classified as other current liabilities.

Commitments, Contingencies and Guarantees [Abstract]

Commitments, Contingencies and Guarantees

3. Commitments, Contingencies and Guarantees

Corning is a defendant in various lawsuits and is subject to various claims that arise in the normal course of business, the most significant of which are summarized below. 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.

Asbestos Claims

Corning and PPG Industries, Inc. each owned 50% of the capital stock of Pittsburgh Corning Corporation (“PCC”). PCC filed for Chapter 11 reorganization in 2000, and the Modified Third Amended Plan of Reorganization for PCC (the “Plan”) became effective in April 2016. At December 31, 2016, the Company’s liability under the Plan was $290 million, which is required to be paid through a series of fixed payments that began in the second quarter of 2017. Payments of $50 million and $35 million were made in June 2019 and June 2018, respectively. The total amount of remaining payments due in years 2020 through 2023 is $135 million, of which $35 million will be paid in the second quarter of 2020 and is classified as a current liability. The remaining $100 million is classified as a non-current liability.

Non-PCC Asbestos Claims

Corning is a defendant in certain cases alleging injuries from asbestos unrelated to PCC (the “non-PCC asbestos claims”) which had been stayed pending the confirmation of the Plan. The stay was lifted on August 25, 2016. At June 30, 2019 and December 31, 2018, the amount of the reserve for these non-PCC asbestos claims was estimated to be $145 million and $146 million, respectively. The reserve balance as of June 30, 2019 represents the undiscounted projection of claims and related legal fees for the estimated life of the litigation.

Dow Corning Chapter 11 Related Matters

Until June 1, 2016, Corning and The Dow Chemical Company (“Dow”) each owned 50% of the common stock of Dow Corning Corporation (“Dow Corning”). On May 31, 2016, Corning and Dow realigned their ownership interest in Dow Corning. Corning retained its indirect ownership interest in the Hemlock Semiconductor Group (“HSG”) and formed a new entity which had been capitalized by Dow Corning with $4.8 billion. Following the realignment, Corning no longer owned any interest in Dow Corning. With the realignment, Corning agreed to indemnify Dow Corning for 50% of Dow Corning’s non-ordinary course, pre-closing liabilities to the extent such liabilities exceed the amounts reserved for them by Dow Corning as of May 31, 2016, including two legacy Dow Corning matters: the Dow Corning Breast Implant Litigation, and the Dow Corning Bankruptcy Pendency Interest Claims.

‎

Dow Corning Breast Implant Litigation

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 as shareholders in exchange for contributions to the Plan.

Under the terms of the Plan, Dow Corning has established and funded a Settlement Trust and a Litigation Facility, referred to above, to provide a means for tort claimants to settle or litigate their claims. Inclusive of insurance, Dow Corning has paid approximately $1.8 billion to the Settlement Trust. As of May 31, 2016, Dow Corning had recorded a reserve for breast implant litigation of $290 million. In the event Dow Corning’s total liability for these claims exceeds such amount, Corning may be required to indemnify Dow Corning for up to 50% of the excess liability, subject to certain conditions and limits. At June 30, 2019, Dow Corning had recorded a reserve for breast implant litigation of $263 million.

Dow Corning Bankruptcy Pendency Interest Claims

As a separate matter arising from the bankruptcy proceedings, Dow Corning is defending claims asserted by commercial creditors who claim additional compounded interest at default and state statutory judgment rates as well as attorneys’ fees and other enforcement costs, during the period from May 1995 through June 2004. As of May 31, 2016, Dow Corning had recorded a reserve for these claims of $107 million. In the event Dow Corning’s liability for these claims exceeds such amount, Corning may be required to indemnify Dow Corning for up to 50% of the excess liability, subject to certain conditions and limits. As of June 30, 2019, Dow Corning had recorded a reserve for these claims of $84 million.

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 15 active hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At June 30, 2019 and December 31, 2018, Corning had accrued approximately $26 million and $30 million, respectively, for the undiscounted 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. Leases

We have operating and finance leases for real estate, vehicles, and equipment.

We incurred lease expense in the amount of $38 million and $80 million for the three and six months ended June 30, 2019. Operating and Financing lease costs were $34 million and $4 million, and $71 million and $9 million, respectively, for the three and six months ended June 30, 2019. Short-term rental expense, for agreements less than one year in duration, is immaterial. For the three and six months ended June 30, 2019, financing lease cost was comprised of expenses for depreciation of right-of-use assets and Interest on lease liabilities in the amounts of $2 million and $4 million, and $2 million and $5 million, respectively.

Cash paid for amounts included in the measurement of lease liabilities totaled $26 million and $55 million for the three and six months ended June 30, 2019. Operating cash outflows from operating and financing leases were $22 million and $48 million, and $2 million and $5 million, respectively. Financing cash outflows from finance leases were nominal.

‎

For the three and six months ended June 30, 2019, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional net tax expense of $86 million driven by changes to our tax reserves, rate differences on income (loss) of consolidated foreign companies, estimated impact of base erosion and anti-deferral tax (“BEAT”) offset by the expected benefits related to foreign derived intangible income (“FDII”) and the release of foreign valuation allowances on deferred tax assets.

For the three months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to a reduction in the estimated impact of BEAT attributable to year-to-date losses from foreign exchange and translated earnings contracts, additional tax amounts related to global intangible low-taxed income (“GILTI”) and a benefit from the release of a foreign valuation allowance on deferred tax assets.

For the six months ended June 30, 2018, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to additional tax expense of $172 million related to a preliminary agreement with the Internal Revenue Service (“IRS”) to settle the income tax audit for the years 2013 and 2014, additional tax amounts related to GILTI and benefits from the release of a foreign valuation allowance on deferred tax assets. The company expects to make a payment before the end of the year of approximately $40 million for the 2013-2014 tax audit settlements with the IRS. As of June 30, 2019, the company is not expecting any significant movements in the uncertain tax benefits in the next twelve months.

(1)The negative carrying value resulted from a one-time charge of $239 million to this entity in 2019 due to the adoption of the new revenue standard. This charge was offset by deferred tax impacts of $53 million. The charge relates to timing of revenue recognition for open performance obligations as measured at January 1, 2019. Most of these performance obligations are expected to be recognized within the next twelve months and the negative carrying value has been reduced by current period income.

Hedging Activities

Hedging Activities [Abstract]

Hedging Activities

10. Hedging Activities

Cash Flow Hedges

Our cash flow hedging activities utilize over-the-counter (“OTC”) foreign exchange forward contracts to reduce the risk that movements in exchange rates will adversely affect the net cash flows resulting from the sale of products to customers and purchases from suppliers. The total gross notional value for foreign currency cash flow hedges are $1.6 billion and $0.4 billion at June 30, 2019 and December 31, 2018, respectively. The majority of our foreign exchange forward contracts hedge a portion of the Company’s exposure to the Japanese yen denominated sales with maturities spanning the years 2020-2023 and with gross notional values of $1.2 billion at June 30, 2019. Corning defers gains and losses related to the cash flow hedges into accumulated other comprehensive loss on the consolidated balance sheets until the hedged item impacts earnings. At June 30, 2019, the amount expected to be reclassified into earnings within the next 12 months is a pre-tax net gain of $11 million.

The effect of cash flow hedges on Corning’s consolidated statements of income and other comprehensive income (loss) is not material for the three and six months ended June 30, 2019 and 2018.

‎

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.

The table below includes a total gross notional value for translated earnings contracts of $13.5 billion and $13.6 billion at June 30, 2019 and December 31, 2018, respectively. These include gross notional value for average rate forwards of $11.0 billion for both periods and zero-cost collars and purchased put or call options of $2.5 billion and $2.6 billion at June 30, 2019 and December 31, 2018, respectively. The majority of our average rate forward contracts hedge a significant portion of the Company’s exposure to the Japanese yen with maturities spanning the years 2019-2023 and with gross notional values of $8.1 billion and $9.1 billion at June 30, 2019 and December 31, 2018, respectively. The average rate forward contracts also partially hedge the impacts of the South Korean won, Chinese yuan, euro, New Taiwan dollar and British pound translation on the Company’s projected net income. With respect to the zero-cost collars, the gross notional amount includes the value of both the put and call options. However, due to the nature of the zero-cost collars, only the put or the call option can be exercised at maturity.

The following tables summarize the notional amounts and respective fair values of Corning’s derivative financial instruments on a gross basis for June 30, 2019 and December 31, 2018 (in millions):

Fair Value Measurements [Abstract]

Fair Value Measurements

11. Fair Value Measurements

Fair value standards under 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.

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
			Quoted prices in	Significant other		Significant
			active markets for	observable		unobservable

Current assets:
Other current assets (1)	$	94		$	94

Current liabilities:
Other accrued liabilities (1)	$	67		$	67
Non-current liabilities:
Other liabilities (1)	$	345		$	345

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

(2)Other assets include one of the Company’s renewable energy derivative contracts that was measured using unobservable (Level 3) inputs, in the amount of $23 million.

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

(2)One of the Company’s equity securities was measured using unobservable (Level 3) inputs, in the amount of $16 million.

(3)Other liabilities include contingent consideration that was measured using unobservable (Level 3) inputs, in the amount of $20 million.

For the six months ended June 30, 2019, assets and liabilities that were measured using unobservable (Level 3) inputs resulted in unrealized gains recognized in earnings of $23 million for a renewable energy derivative contract and the reversal of a liability for contingent consideration of $20 million.

There were no significant financial assets and liabilities measured on a nonrecurring basis as of June 30, 2019 and December 31, 2018.

12. Shareholders’ Equity

Fixed Rate Cumulative Convertible Preferred Stock, Series A

Corning has 2,300 outstanding shares of Fixed Rate Cumulative Convertible Preferred Stock, Series A. The Preferred Stock is convertible at the option of the holder and the Company upon certain events, at a conversion rate of 50,000 shares of Corning’s common stock per one share of Preferred Stock, subject to certain anti-dilution provisions. As of June 30, 2019, the Preferred Stock has not been converted, and none of the anti-dilution provisions have been triggered.

Share Repurchases

In December 2016, Corning’s Board of Directors approved a $4 billion share repurchase program with no expiration date (the “2016 Repurchase Program”). On April 26, 2018, Corning’s Board of Directors approved a $2 billion share repurchase program with no expiration date (the “2018 Repurchase Program”).

In the three and six months ended June 30, 2019, the Company repurchased 4.8 and 12.6 million shares of common stock on the open market for approximately $151 million and $395 million, respectively, as part of its 2018 Repurchase Program.

Reportable Segments [Abstract]

Reportable Segments

13. Reportable Segments

Our reportable segments are as follows:

Display Technologies – manufactures glass substrates for flat panel liquid crystal displays and other high-performance display panels.

Optical Communications – manufactures carrier and enterprise network components for the telecommunications industry.

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.

Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.

Life Sciences – manufactures glass and plastic labware, equipment, media and reagents enabling workflow solutions for scientific applications.

All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This group is primarily comprised of the results of the pharmaceutical technologies business and new product lines and development projects, as well as certain corporate investments such as Eurokera and Keraglass equity affiliates.

We prepared the financial results for our reportable segments on a basis consistent with our internal disaggregation of financial information to assist our chief operating decision maker (“CODM”) in making internal operating decisions. The impact of changes in the Japanese yen, Korean won, Chinese yuan and new Taiwan dollar are excluded from segment sales and segment net income for the Display Technologies and Specialty Materials segments. The impact of changes in the euro, Chinese yuan and Japanese yen are excluded from segment sales and segment net income for our Environmental Technologies and Life Sciences segments. In January 2019, we began presenting results of the Environmental Technologies and Life Sciences segments on a constant-currency basis to mitigate the translation impact on these segments’ sales and net income. We have not recast prior periods as the impact of fluctuations in these currencies were not material as compared to prior periods. Certain income and expenses are included in the unallocated amounts in the reconciliation of reportable segment net income to consolidated net income. These include items that are not used by our CODM in evaluating the results of or in allocating resources to our segments and include the following items: the impact of our translated earnings contracts; acquisition-related costs; discrete tax items and other tax-related adjustments; certain litigation, regulatory and other legal matters; restructuring, impairment and other charges and credits; adjustments relating to acquisitions; and other non-recurring non-operational items. Although we exclude these amounts from segment results, they are included in reported consolidated results.

We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income. We have allocated certain common expenses among reportable segments differently than we would for stand-alone financial information. Segment net income may not be consistent with measures used by other companies.

Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and its 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. Generally Accepted Accounting Principles (“GAAP”) for interim financial information. Certain information and note disclosures normally included in financial statements prepared in accordance with 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, 2018 (“2018 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.

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.

Leases

Leases

Corning leases certain real estate, vehicles, and equipment from third parties. On January 1, 2019 we adopted the new leasing standard. Corning classifies leases as either financing or operating. Operating leases are included in other assets with the corresponding liability in other accrued liabilities and other liabilities on our consolidated balance sheets. Finance leases are included in property, plant and equipment with the corresponding liability in the current portion and long-term debt line items on our consolidated balance sheets. Leases where we are the lessor are not significant.

Lease expense is recognized on a straight-line basis over the lease term for operating leases. Financing leases are recognized on the effective interest method for interest expense and straight-line method for asset amortization. Renewals and terminations are included in the calculation of the Right of Use (“ROU”) assets and lease liabilities when considered to be reasonably certain to be exercised. When the implicit rate is unknown, we use our incremental borrowing rate based on commencement date in determining the present value of lease payments.

Our leases do not include residual value guarantees. We are not the primary beneficiary in or have other forms of variable interests with the lessor of the leased assets. The impact to the balance sheet for operating leases is a gross-up for the addition of ROU assets and liabilities relating to the operating leases in the amount of $449 million at adoption. The impact to the balance sheet for financing leases was not material.

Corning has elected the following practical expedients and accounting policy elections to apply the new lease accounting standard at its effective date as of January 1, 2019:

Leases of less than 12 months in duration to be recorded as expense only;

Account for lease and non-lease components of a contract as a single lease component; and

Comparative reporting of prior periods under ASC 840 not restated due to modified retrospective implementation.

At adoption, Corning recorded a nominal cumulative-effect adjustment to beginning retained earnings.

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

Revenue

Revenue

One of Corning’s equity affiliates adopted the new revenue standard on January 1, 2019.  The impact of adopting the new standard to Corning’s financial statements was a net reduction of $186 million to 2019 beginning retained earnings. Timing of revenue recognition for certain open performance obligations as measured at January 1, 2019 under the new standard was approximately $239 million with offsetting deferred tax impacts of $53 million.

Income Taxes

Income Taxes

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, which allows for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. We have adopted this new standard effective January 1, 2019. The impact of the new standard resulted in a reclassification of $53 million from accumulated other comprehensive income (“AOCI”) to beginning retained earnings.

Other Accounting Standards

Other Accounting StandardsNo other accounting standards newly issued or adopted as of June 30, 2019, had a material impact on Corning’s financial statements or disclosures.

(1)The negative carrying value resulted from a one-time charge of $239 million to this entity in 2019 due to the adoption of the new revenue standard. This charge was offset by deferred tax impacts of $53 million. The charge relates to timing of revenue recognition for open performance obligations as measured at January 1, 2019. Most of these performance obligations are expected to be recognized within the next twelve months and the negative carrying value has been reduced by current period income.

[1] The negative carrying value resulted from a one-time charge of $239 million to this entity in 2019 due to the adoption of the new revenue standard. This charge was offset by deferred tax impacts of $53 million. The charge relates to timing of revenue recognition for open performance obligations as measured at January 1, 2019. Most of these performance obligations are expected to be recognized within the next twelve months and the negative carrying value has been reduced by current period income.

[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. Expenses that are not allocated to the segments are included in the reconciliation of reportable segment net income to consolidated net income below.
