Item 7.01  Regulation FD Disclosure.  

Corning Incorporated (the “Company”) adopted the use of core performance measures as a supplement to U.S. generally accepted accounting principles (“GAAP”) in early 2013 when the Japanese yen began a significant weakening trend relative to the U.S. dollar.  Corning used a yen-to-dollar rate (“constant-yen”) of ¥93 for its core reporting in 2013 and 2014, and a constant yen rate of ¥99 for its core reporting in 2015, 2016 and 2017, which aligned with the Company’s yen-denominated hedge rates during these time periods.  Additionally, because a significant portion of Corning Precision Materials’ costs are denominated in Korean won, beginning in 2014, the Company used an internally derived won-to-dollar rate (“constant-won”) of ₩1,100 for its core reporting, which was consistent with historical prior period averages of the won.

Beginning with the first quarter of 2018, the Company is changing the constant-yen and constant-won rates used in the calculation of its core performance measures to ¥107, which closely aligns with yen-denominated hedges entered into for the years 2018 through 2020,and₩1,175, which aligns with our current won portfolio of foreign currency hedges.    The Company believes that the use of constant currency reporting allows investors to understand our results without the impact of volatile changes in currency exchange rates on our net sales and net income. 

Exhibit 99 to this Form 8-K provides recasted core performance measures for Corning Incorporated in total, as well as the Display Technologies and Specialty Materials segments, for the years ended December 31, 2017 and 2016, and quarters ended March 31, 2017 and 2016, June 30, 2017 and 2016, September 30, 2017 and 2016, and December 31, 2017 and 2016.   Corning’s remaining segments are not impacted by the change in constant-yen and constant-won.

In  Exhibit 99, the Company discloses items not prepared in accordance with GAAP, or non-GAAP financial measures (as defined in Regulation G promulgated by the U.S. Securities and Exchange Commission).  In managing the Company and assessing our financial performance, we supplement certain GAAP measures provided by our consolidated financial statements with measures adjusted to exclude certain items to arrive at core performance measures.  The Company believes that reporting core performance measures allows investors to understand our results without the volatility of currency fluctuations, as well as other non-operational items, 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.

The recasting of previously issued financial information does not represent a restatement of previously issued financial statements and does not affect the Company’s reported sales, gross margin, selling, general and administrative expenses, equity earnings, net income or earnings per share, for any of the previously reported periods.  The information contained in this Form 8-K is being furnished pursuant to Regulation FD in order to provide the financial community with historical financial data that is presented on a basis consistent with the Company’s core performance measure reporting structure.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Reconciliation of Non-GAAP Measures

In managing the Company and assessing our financial performance, we supplement certain measures provided by our consolidated financial statements with measures adjusted to exclude certain items, to arrive at core performance measures.  We believe that reporting core performance measures provides investors greater transparency to the information used by our management team to make financial and operational decisions.  Corning has adopted the use of constant currency reporting for the Japanese yen and South Korean won, and, beginning in the first quarter of 2018, uses an internally derived yen-to-dollar management rate of ¥107 and won-to-dollar management rate of ₩1,175.  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 contract used to mitigate the impact of changes in currency exchange rates on our earnings and cash flows.

Net sales, equity in earnings of affiliated companies and net income are adjusted to exclude the impacts of changes in the Japanese yen and the South Korean won, 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.  Management’s discussion and analysis on our reportable segments has also been adjusted for these items, as appropriate.  These measures are not prepared in accordance with Generally Accepted Accounting Principles in the United States (“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.  See “Items which we exclude from GAAP measures to arrive at Core performance measures”  for details on core performance measures.

Items which we exclude from GAAP measures to arrive at Core performance measures are as follows:

(1)	Constant-currency adjustments:
	Constant-yen:  Because a significant portion of Display Technologies segment revenues and manufacturing costs are denominated in Japanese yen, management believes it is important to understand the impact on core earnings of translating yen into dollars.  Presenting results on a constant-yen basis mitigates the translation impact of the Japanese yen, and allows management to evaluate performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts.  As of January 1, 2018, we use an internally derived management rate of ¥107, which is closely aligned to our current yen portfolio of foreign currency hedges, and have recast all periods presented based on this rate in order to effectively remove the impact of changes in the Japanese yen.
	Constant-won:  Because a significant portion of Corning Precision Materials’ costs are denominated in South Korean won, management believes it is important to understand the impact on core earnings from translating won into dollars.  Presenting results on a constant-won basis mitigates the translation impact of the South Korean won, and allows management to evaluate performance period over period, analyze underlying trends in our businesses, and establish operational goals and forecasts without the variability caused by the fluctuations caused by changes in the rate of this currency.  We use an internally derived management rate of ₩1,175, which isclosely aligned to our current won portfolio of foreign currency hedges, and have recast all periods presented based on this rate in order to effectively remove the impact of changes in the South Korean won.
(2)	Translation gain on Japanese yen-denominated debt:  The gain 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 and South Korean won-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our euro, New Taiwan dollar and Chinese yuan-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:  This represents the removal of discrete adjustments (e.g. changes in tax law and changes in judgment about the realizability of certain deferred tax assets) as well as other non-operational tax-related adjustments.
(6)	Litigation, regulatory and other legal matters:  Includes amounts related to legal matters.
(7)	Restructuring, impairment and other charges:  This amount includes restructuring, impairment and other charges, including goodwill impairment charges and other expenses and disposal costs not classified as restructuring expense.
(8)	Equity in earnings of affiliated companies:  These adjustments relate to items which do not reflect expected on-going operating results of our affiliated companies, such as restructuring, impairment and other charges and settlements under “take-or-pay” contracts.
(9)	Adjustments related to acquisitions:  Includes fair value adjustments to the Corning Precision Materials indemnity asset related to contingent consideration, post-combination expenses and other acquisition and disposal adjustments.
(10)	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.
(11)	Gain on realignment of equity investment:  Gain recorded upon the completion of the strategic realignment of our ownership interest in Dow Corning.
(12)	Taiwan power outage:  Impact of the power outage that temporarily halted production at our Tainan, Taiwan manufacturing location in the second quarter of 2016.  The impact includes asset write-offs and charges for facility repairs, offset somewhat by partial reimbursement through our insurance program.
(13)	Adjustments to remove the impact of the Tax Cuts and Job Act:  Includes a provisional amount related to the one-time mandatory tax on unrepatriated foreign earnings, a provisional amount related to the remeasurement of U.S. deferred tax assets and liabilities, changes in valuation allowances as a result of the 2017 Tax Act, and adjustments for the elimination of foreign tax credits.
