Basis Of Presentation [Abstract]
Basis Of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Ferro Corporation (“Ferro,” “we,” “us” or “the Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, the instructions to Form 10-Q, and Article 10 of Regulation S-X. These statements reflect all normal and recurring adjustments which are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017 .  We produce our products primarily in the Europe, Middle East and Africa (“EMEA”) region, the United States, the Asia Pacific region, and Latin America.  Operating results for the three and nine months ended September 30, 2018 , are not necessarily indicative of the results expected in subsequent quarters or for the full year ending December 31, 2018 .

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements Recently Adopted Accounting Standards On April 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 provides guidance to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The adoption of this ASU did not have an impact to the opening balance of Retained earnings. We will apply the guidance of this ASU to applicable future transactions. On April 1, 2018, we adopted FASB ASU 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2018-03 provides targeted improvements to address certain aspects of recognition, measurement presentation, and disclosure of financial instruments. The adoption of ASU 2018-03 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-09, Compensation – Stock Compensation: (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This new guidance would only impact our consolidated financial statements if, in the future, we modified the terms of any of our share-based awards. We will apply the guidance of this ASU to applicable future transactions. The adoption of ASU 2017-09 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-07, Compensation – Retirement Benefits: (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Costs. ASU 2017-07 requires that an employer report the service cost component in the same line item as other compensation costs arising from services rendered during the period. The other components of net benefit costs are to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This ASU also allows only the service cost component of net benefit costs to be eligible for capitalization. We adopted this ASU using the retrospective approach for the presentation of the service cost component and the other components of the net periodic pension (credit) cost and net periodic postretirement benefit cost in the income statement. This resulted in the reclassification of income of $0.5 million and $1.4 million from Selling, general and administrative expenses to Other income, expense in our condensed consolidated statement of operations for the three and nine months ended September 30, 2018, respectively. The Company used a practical expedient where the amount disclosed in our Retirement Benefits footnote for the prior year comparative period was the basis for the estimation for applying the retrospective presentation requirements. Other than this reclassification, the adoption of ASU 2017-07 did not have an impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-01, Business Combinations: (Topic 805): Clarifying the Definition of a Business. ASU 2017-01 is intended to clarify the definition of a business with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. We will apply the guidance of this ASU to applicable future transactions. The adoption of ASU 2017-01 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2016-16, Income Taxes: (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory and requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. We adopted this ASU using the modified retrospective method. The impact of adopting this guidance on the Company’s condensed consolidated financial statements resulted in an increase to Retained earnings of $4.1 million and Deferred income taxes of $4.7 million and a decrease to Other receivables of $0.6 million on January 1, 2018 . On January 1, 2018 , we adopted FASB ASU 2016-15, Statement of Cash Flow: (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to address eight specific cash flow issues with the objective of reducing the existing diversity in practice. Adoption of ASU 2016-15 did not have a material effect on our condensed consolidated financial statements.  On January 1, 2018, we adopted FASB ASU 2014-09, Revenue from Contracts with Customers: (Topic 606) (“ASC 606”) . This ASU replaces nearly all existing U.S. GAAP guidance on revenue recognition. The standard prescribes a five-step model for recognizing revenue, the application of which require significant judgment. We have completed our assessment and review of specific contracts and have adopted this ASU using the modified retrospective method with no impact to the opening Retained earnings balance. We expect the impact of the adoption of this ASU will not have a material effect on our consolidated financial statements on an ongoing basis.  New Accounting Standards In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This pronouncement is effective for fiscal years beginning after December 15, 2020. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. This pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows a reclassification from Accumulated Other Comprehensive (Loss) Income to Retained Earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and requires certain disclosures about stranded tax effects. This pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 is intended to simplify the subsequent measurement of goodwill by eliminating Step 2 from the current goodwill impairment test. This pronouncement is effective for the annual or any interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements.  In February 2016, the FASB issued ASU 2016-02, Leases: (Topic 842). ASU 2016-02 requires companies to recognize a lease liability and asset on the balance sheet for operating leases with a term greater than one year. In July 2018, the FASB issued ASU 2018-11, Targeted Improvements . This ASU provides an additional transition method to adopt the new leasing standard. Under this new transition method, an entity initially applies the new leasing standard using a cumulative-effect adjustment to the opening balance of retained earnings but will continue to report comparative periods under existing guidance in accordance with ASC 840, Leases . The amendments in ASU 2018-11 are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company has elected to adopt ASU 2016-02 using this new transition method. The Company is in the process of assessing the impact the adoption of this ASU will have on our consolidated financial statements.  No other new accounting pronouncements issued had, or are expected to have, a material impact on the Company’s consolidated financial statements.

Revenue

Revenue [Abstract]
Revenue	3. Revenue  Revenue Recognition  Under ASC 606, revenues are recognized when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods. In order to achieve that core principle, the Company applies the following five-step approach: 1) identify the contract with a customer, 2) identify the performance obligations, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when a performance obligation is satisfied.  The Company considers confirmed customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts, from an accounting perspective, with customers. Under our standard contracts, the only performance obligation is the delivery of manufactured goods and the performance obligation is satisfied at a point in time, when the Company transfers control of the manufactured goods . The Company may receive orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each order and recognizes revenue for each distinct product upon shipment, once transfer of control has occurred. Payment terms are standard for the industry and jurisdiction in which we operate. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment, to determine the net consideration to which the Company expects to be entitled. Discounts or rebates are specifically stated in customer contracts or invoices, and are recorded as a reduction of revenue in the period the related revenue is recognized. The product price as specified on the customer confirmed orders is considered the standalone selling price. The Company allocates the transaction price to each distinct product based on its relative standalone selling price. Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which generally occurs at shipment. We review material contracts to determine transfer of control based upon the business practices and legal requirements of each country.  The amount of shipping and handling fees invoiced to our customers at the time our product is shipped is included in net sales as we are the principal in those activities. Sales, valued-added and other taxes collected from our customers and remitted to governmental authorities are excluded from net sales.  There were no changes in amounts previously reported in the Company’s condensed consolidated financial statements due to adopting ASC 606.      Revenues disaggregated by geography and reportable segment for the three months ended September 30, 2018, follow:     EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 110,261 $ 12,170 $ 27,914 $ 25,594 $ 175,939  Performance Colors and Glass 55,782 43,087 18,564 5,844 123,277  Color Solutions 33,276 43,699 10,136 8,836 95,947  Total net sales $ 199,319 $ 98,956 $ 56,614 $ 40,274 $ 395,163  Revenues disaggregated by geography and reportable segment for the three months ended September 30, 2017, follow:     EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 83,910 $ 11,365 $ 24,264 $ 26,699 $ 146,238  Performance Colors and Glass 52,408 35,836 16,663 5,671 110,578  Color Solutions 33,400 41,190 9,937 8,669 93,196  Total net sales $ 169,718 $ 88,391 $ 50,864 $ 41,039 $ 350,012  Revenues disaggregated by geography and reportable s egment for the nine months ended September 30, 2018, follow:     EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 355,510 $ 36,704 $ 82,990 $ 78,832 $ 554,036  Performance Colors and Glass 180,801 118,682 53,142 17,184 369,809  Color Solutions 109,985 126,598 30,606 25,900 293,089  Total net sales $ 646,296 $ 281,984 $ 166,738 $ 121,916 $ 1,216,934  Revenu es disaggregated by geography and reportable segment f or the nine months ended September 30 , 2017, follow:     EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 241,884 $ 33,727 $ 68,670 $ 80,268 $ 424,549  Performance Colors and Glass 144,586 112,772 47,091 16,284 320,733  Color Solutions 103,538 118,886 26,971 24,522 273,917  Total net sales $ 490,008 $ 265,385 $ 142,732 $ 121,074 $ 1,019,199   Practical Expedients and Exemptions  All material contracts have an original duration of one year or less and, as such, the Company uses the practical expedient applicable to such contracts, and has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period, or when the Company expects to recognize this revenue.  When the period of time between the transfer of control of the goods and the time the customer pays for the goods is one year or less, the Company uses the practical expedient allowed by ASC 606 that provides relief from adjusting the amount of promised consideration for the effects of a financing component.  We generally expense sales commissions when incurred because the amortization period is one year or less. These costs are recorded within Selling, general and administrative expenses.

The (“Tranche B-2 Loans”) are borrowed by the Company and the (“Tranche B-3 Loans”) are borrowed on a joint and several basis by Ferro GmbH and Ferro E urope Holdings LLC . The Amended Credit Facility consists of a $500 million secured revolving line of credit with a maturity of February 2023, a $355 million secured term loan facil ity with a maturity of February 2024, a $235 million secured term loan facility with a maturity of February 2024 and a $230 million sec ured term loan facility with a maturity of February 2024. The term loans are payable in equal quarterly installments in an amount equal to 0.25% of the original principal amount of the term loans, with the remaining balance due on the maturity date thereof. In addition, the Company is required, on an annual basis, to make a prepayment in an amount equal to a portion of the Company’s excess cash flow, as calculated pursuant to the Amended Credit Facility, which prepayment will be applied first to the term loans until they are paid in full, and then to the revolving loans. Subject to the satisfaction of certain conditions, the Company can request additional commitments under the revolving line of credit or term loans in the aggregate principal amount of up to $250 million to the extent that existing or new lenders agree to provide such additional commitments and/or term loans . The Company can also raise certain additional debt or credit facilities subject to satisfaction of certain covenant levels. Certain of the Company’s U.S. subsidiaries have guaranteed the Company’s obligations under the Amended Credit Facility and such obligations are secured by (a) substantially all of the personal property of the Company and the U.S. subsidiary guarantors and (b) a pledge of 100% of the stock of certain of the Company’s U.S. subsidiaries and 65% of the stock of certain of the Company’s direct foreign subsidiaries.

The variable margin will be based on the ratio of (a) the Company’s total consolidated net debt outstanding (as defined in the Amended Credit Agreement) at such time to (b) the Company’s consolidated EBITDA (as defined in the Amended Credit Agreement) computed for the period of four consecutive fiscal quarters most recently ended. · The base rate for revolving loans will be the highest of (i) the federal funds rate plus 0.50% , (ii) syndication agent’s prime rate, (iii) the daily LIBOR rate plus 1.00% or (iv) 0.00%.

The fair values of cash and cash equivalents are based on the fair values of identical assets. The fair values of loans payable are based on the present value of expected future cash flows and approximate their carrying amounts due to t he short periods to maturity. The fair value of the term loan fac ility is based on market price information and is measured using the last available bid price of the instrument on a secondary market. The revolving credit facility and other long-term notes payable are based on the present value of expected future cash flows and interest rates that would be currently available to the Company for issuance of similar types of debt instruments with similar terms and remaining maturities adjust ed for the Company's performance risk. The fair values of our interest rate swaps and cross currency swaps are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. The fair values of the foreign currency forward contracts are based on market prices for comparable contracts. Derivative Instruments  The Company may use derivative instruments to partially offset its business exposure to foreign currency and interest rate risk on expected future cash flows, on net investment in certain foreign subsidiaries and on certain existing assets and liabilities. However, the Company may choose not to hedge in countries where it is not economically feasible to enter into hedging arrangements or where hedging inefficiencies exist, such as timing of transactions. Derivatives Designated as Hedging Instruments Cash Flow Hedges. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is recorded in Accumulated other comprehensive loss (“AOCL”) and reclassified into earnings in the same period during which the hedged transaction affects earnings. The Company utilizes interest rate swaps to limit exposure to market fluctuations on floating-rate debt. During the second quarter of 2017, the Company entered into interest rate swap agreements that converted $150 million and €90 million of our term loans from variable interest rates to fixed interest rates. These swaps qualified for, and were designated as, cash flow hedges. This interest rate swap agreement was terminated in the second quarter of 2018 in connection with the refinancing of the Credit Facility. During the second quarter of 2018, the Company entered into variable to fixed interest rate swap s with a maturity date of February 28, 2024 . The notional amount is $318. 4 million at September 30, 2018 . These swaps are hedging risk associated with the Tranche B-1 Loans. These interest rate swaps are designated as cash flow hedge s . As of September 30 , 2018, the Company exp ects it will reclassify net losses of approximately $0. 7 million, currently recorded in AOCL, into earnings within the next twelve months. However, the actual amount reclassified could vary due to future changes in the fair value of these derivatives. The Company has converted a US dollar denominated, variable rate debt obligation into a euro fixed rate obligation using a receive-float, pay fixed cross currency swaps in the second quarter of 2018. These swaps are hedging risk associated with the Tranche B-3 Loans. These cross currency swap s are designated as cash flow hedge s . T he notional amount is $2 28.9 million at September 30, 2018, with a maturity date of February 28, 2024. As o f September 30 , 2018, the Company expects it will reclassify net gains of approximately $5. 9 million , currently recorded in AOCL, into earnings within the next twelve months. However, the actual amount reclassified could vary due to future changes in the fair value of these derivatives. The amount of gain recognized in AOCL and the amount of (loss) gain reclassified into earnings for the three months ended September 30, 2018 and 2017, follow:    Amount of (Loss) Gain  Amount of Gain Reclassified from Location of (Loss) Gain  Recognized in AOCL AOCL into Income Reclassified from  2018 2017 2018 2017 AOCL into Income  (Dollars in thousands)  Interest rate swaps $ 2,135 $ 166 $ (186) $ — Interest expense  Cross currency swaps 3,237 — 1,327 — Interest expense  $ 1,141 $ Total Interest expense  Cross currency swaps 1,549 — Foreign currency losses, net  $ 1,549 $ — Total Foreign currency losses, net The amount of gain recognized in AOCL and the amount of (loss) gain reclassified into earnings for the nine months ended September 30, 2018 and 2017, follow:    Amount of (Loss) Gain  Amount of Gain Reclassified from Location of (Loss) Gain  Recognized in AOCL AOCL into Income Reclassified from  2018 2017 2018 2017 AOCL into Income  (Dollars in thousands)  Interest rate swaps $ 1,761 $ 166 $ (197) $ — Interest expense  Cross currency swaps 12,666 — 2,215 — Interest expense  $ 2,018 $ — Total Interest expense  Cross currency swap 11,864 — Foreign currency losses, net  $ 11,864 $ — Total Foreign currency losses, net Net investment hedge. To help protect the value of the Company’s net investment in European operations against adverse changes in exchange rates, the Company uses non-derivative financial instruments, such as its foreign currency denominated debt, as economic hedges of its net investments in certain foreign subsidiaries. Net investment hedges that use foreign currency denominated debt to hedge net investments are not impacted by ASC Topic 820, Fair Value Measurements, as the debt used as a hedging instrument is marked to a value with respect to changes in spot foreign currency exchange rates and not with respect to other factors that may impact fair value. In the second quarter of 2017, the Company designated a portion of its Euro denominated debt as a net investment hedge for accounting purposes. This net investment hedge was terminated in the second quarter of 2018. In the second quarter of 2018, the Company entered into cross currency swap agreement s where we pay variable rate interest in Euros and receive variable rate interest in US dollars. The notional amount is $116.9 million at September 30, 2018. These swaps are hedging risk associated with the Tranche B-2 Loans. These cross currency swap s are designated as net investment hedge s with the spot method of accounting applied . The effective portions of net investment hedges are recorded in AOCL as a part of the cumulative translation adjustment. The amount of gain (loss) recognized in AOCL, the amount reclassified into earnings and the amount of gain recognized in income on derivative (amount excluded from effectiveness testing) for the three months ended September 30, 2018 and 2017, follow :     Amount of Gain Amount of Gain Recognized in  Amount of Gain (Loss) Reclassified from Income on Derivative (Amount  Recognized in AOCL AOCL into Income Excluded from Effectiveness Testing) Location of Gain  2018 2017 2018 2017 2018 2017 (Loss) in Earnings  (Dollars in thousands)  Cross currency swaps $ 1,272 $ — $ — $ — $ 858 $ — Interest expense  Net investment hedge — (8,020) — — — — Foreign currency losses, net The amount of gain (loss) recognized in AOCL, the amount reclassified into earnings and the amount of gain recognized in income on derivative (amount excluded from effectiveness testing) for the nine months ended September 30, 2018 and 2017, follow :     Amount of Gain Amount of Gain Recognized in  Amount of Gain (Loss) Reclassified from Income on Derivative (Amount  Recognized in AOCL AOCL into Income Excluded from Effectiveness Testing) Location of Gain  2018 2017 2018 2017 2018 2017 (Loss) in Earnings  (Dollars in thousands)  Cross currency swaps $ 4,046 $ — $ — $ — $ 1,353 $ — Interest expense  Net investment hedge — (14,848) — — — — Foreign currency losses, net  Derivatives Not Designated as Hedging Instruments Foreign currency forward contracts. We manage foreign currency risks principally by entering into forward contracts to mitigate the impact of currency fluctuations on transactions. These forward contracts are not formally designated as hedges. Gains and losses on these foreign currency forward contracts are netted with gains and losses from currency fluctuations on transactions arising from international trade and reported as Foreign currency losses, net in the condensed consolidated statements of operations. We recognized net gains of $1.3 million and $2.7 million in the three and nine months ended September 30, 2018 , respectively, and net losses of $1.4 million and $4.1 million in the three and nine months ended September 30, 2017 , respectively, arising from the change in fair value of our financial instruments, which partially offset the related net gains and losses on international trade transactions. The notional amount of foreign currency forward contracts was $371.1 million at September 30, 2018 , and $238.5 million at December 31, 2017 .

Income Taxes [Abstract]
Income Taxes	10. Income Taxes Income tax expense for the nine months ended September 30, 2018, was $29. 2 million, or 29.6% of pre -tax income. Income tax expense for the nine months ended September 30, 2017, was $23.2 million, or 25.9% of pre-tax income. The tax expense for the nine months ended September 30, 2018, as a percentage of pre-tax income, is higher than the U.S. federal statutory income tax rate of 21% primarily as a result of foreign statutory rate differences and discrete items recorded in the third quarter. The discrete items recorded in the third quarter primarily include a reduction to the tax expense related to the provision to return adjustments and an increase from the impact of resolving a foreign tax audit. The tax expense for the nine months ended September 30, 2017, as a percentage of pre-tax income, is lower than the U.S. federal statutory income tax rate of 35% primarily as a result of foreign statutory rate differences.  We have recognized the provisional tax impacts related to the 2017 Tax Cut and Jobs Act (the “Tax Act”) under the guidance of the SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). The ultimate impact may differ from these provisional amounts due to additional analysis, changes in interpretations and assumptions, additional regulatory guidance that may be issued, and actions we may take as a result of the Tax Act. The Company’s preliminary determinations related to the estimable impacts of the Tax Act that are effective for the year ended December 31, 2017 have not changed in the current quarter.  The Company continues to review the anticipated impacts of the global intangible low taxed income (“GILTI”) and the foreign-derived intangible income (“FDII”) on the Company for 2018. For the current quarter the company has made reasonable estimates of GILTI and FDII, as well as the impact of changes to valuation allowances related to certain positions. The combined provisional net impact of these items are not anticipated to be material to the tax rate in 2018. The Company has not recorded any potential deferred tax effects related to GILTI in the financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI or use the period cost method.

Contingent Liabilities [Abstract]
Contingent Liabilities	11. Contingent Liabilities We have recorded environmental liabilities of $6.9 m illion at September 30, 2018 , and $6.7 million at December 31, 2017 , for costs associated with the remediation of certain of our properties that hav e been contaminated. The liability at September 30, 2018 , and December 31, 2017 , was primarily comprised of liabilities related to a non-operating facility in Brazil, and for retained environmental obligations related to a site in the United States that was part of the sale of our North American and Asian metal powders product lines in 2013. The costs include legal and consulting fees, site studies, the design and implementation of remediation plans, post-remediation monitoring and related activities. The ultimate liability could be affected by numerous uncertainties, including the extent of contamination found, the required period of monitoring and the ultimate cost of required remediation. During the third quarter of 2018, the Company incurred a $1.5 million environmental liability related to acquired subsidiaries.  In November 2017, Suffolk County Water Authority filed a complaint, Suffolk County Water Authority v. The Dow Chemical Company et al., against the Company and a number of other companies in the U.S. Federal Court for the Eastern District of New York with regard to the product 1,4 dioxane. The plaintiff alleges, among other things, that the Suffolk County water supply is contaminated with 1,4 dioxane and that the defendants are liable for unspecified costs of cleanup and remediation of the water supply, among other damages. The Company has not manufactured 1,4 dioxane since 2008, denies the allegations related to liability for the plaintiff’s claims, and is vigorously defending this proceeding. In March 2018, the defendants, including the Company, filed a motion to dismiss the complaint, which was heard by the court in June 2018. The Company currently does not expect the outcome of this proceeding to have a material adverse impact on its consolidated financial condition, results of operations, or cash flows, net of any insurance coverage. However, it is not possible to predict the ultimate outcome of this proceeding due to the unpredictable nature of litigation.  In addition to the proceeding described above, the Company and its consolidated subsidiaries are subject from time to time to various claims, lawsuits, investigations, and proceedings related to products, services, contracts, environmental, health and safety, employment, intellectual property, and other matters, including with respect to divested businesses. The outcome of such matters is unpredictable, our assessment of them may change, and resolution of them could have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. We do not currently expect the resolution of such matters to materially affect the consolidated financial position, results of operations, or cash flows of the Company.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	13. Stock-Based Compensation On May 3, 2018 , ou r shareholders approved the 2018 Omnibus Incentive Plan (the “Plan”), which was adopted by the Board of Directors on Februa ry 22, 2018 , subject to shareholder approval. The Plan’s purpose is to promote the Company’s long-term financial interests and growth by attracting , retaining and motivating high- quality key employees and directors, motivating such employees and directors to achieve the Company’s short- and long-range p erformance goals and objectives, and thereby align t heir interests with those of the Company’s shareholders. The Plan reserves 4,500,000 shares of common stock to be issued for grants of several different types of long-term incentives including stock options, stock appreciation rights, restric ted awards, performance awards, other common stock- based awards, and dividend equivalent rights. T he 2013 Omnibus Incentive Plan (the “ Previous Plan”), was replaced by the Plan, and no future grants may be made under the Previous Plan. However, any outstanding awards or grants made under the Previous Plan will continue until the end of their specified terms.  In the first nine months of 2018 , our Board of Directors gran ted 0.2 million stock options, 0.1 million performance share units , and 0.1 million restricted stock units . We estimate the fair value of each stock option on the date of grant using the Black-Scholes option pricing model. The following table details the weighted-average grant-date fair values and the assumptions used for estimating the fair values of stock option grants made during the nine months ended September 30, 2018 :      Stock Options  Weighted-average grant-date fair value $ 8.91  Expected life, in years 5.4  Risk-free interest rate 2.7 %  Expected volatility 39.7 %  The weighted average grant date fair value of our performance share units granted in the nine months ended September 30, 2018 , was $22.92 . We measure the fair value of performance share units based on the closing market price of our common stock on the date of the grant. These shares are evaluated each reporting period for respective attainment rates against the performance criteria . The weighted-average grant date fair value per unit for grants made during the nine months ended September 30, 2018 , was $22.27 . We measure the fair value of restricted share units based on the closing market price of our common stock on the date of the grant . The restricted share units vest over three years. We recognized stock-based compensation expense of $1.4 million and $5.2 million for the three and nine months ended September 30, 2018 , respectively, and $1.5 million and $6.9 million for three and nine months ended September 30, 2017 . At September 30, 2018 , unearned compensation cost related to the unvested portion of all stock-based compensation awards was approximately $7.7 million and is expected to be recognized over the remaining vesting period of the respective grants , through the first quarter of 2021 .

Subsequent Events On October 1, 2018, the Company acquired 100% of the equity interests of Quimicer, S.A. for €27.8 million ( approximately $32.2 million), excluding customary adjustments and fees. The operating results related to the Quimicer, S.A. acquisition will be included in the Company’s condensed consolidated financial statements commencing on the date of the acquisition. Due to the timing of the acquisition, the Company’s initial purchase price accounting was incomplete at the time these financial statements were issued. As such, the Company cannot disclose the allocation of the acquisition price to acquired assets and liabilities and the related disclosures at this time. In October 2018, t he Company’s Board of Directors approved a new share repurchase program under which the Company is authorized to repurchase up to an additional $50 million of the Company’s outstanding common stock on the open market, including through Rule 10b5-1 plan s , in privately negotiated transactions, or otherwise.

Recently Adopted Accounting Standards	Recently Adopted Accounting Standards On April 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 provides guidance to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The adoption of this ASU did not have an impact to the opening balance of Retained earnings. We will apply the guidance of this ASU to applicable future transactions. On April 1, 2018, we adopted FASB ASU 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2018-03 provides targeted improvements to address certain aspects of recognition, measurement presentation, and disclosure of financial instruments. The adoption of ASU 2018-03 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-09, Compensation – Stock Compensation: (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This new guidance would only impact our consolidated financial statements if, in the future, we modified the terms of any of our share-based awards. We will apply the guidance of this ASU to applicable future transactions. The adoption of ASU 2017-09 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-07, Compensation – Retirement Benefits: (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Costs. ASU 2017-07 requires that an employer report the service cost component in the same line item as other compensation costs arising from services rendered during the period. The other components of net benefit costs are to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This ASU also allows only the service cost component of net benefit costs to be eligible for capitalization. We adopted this ASU using the retrospective approach for the presentation of the service cost component and the other components of the net periodic pension (credit) cost and net periodic postretirement benefit cost in the income statement. This resulted in the reclassification of income of $0.5 million and $1.4 million from Selling, general and administrative expenses to Other income, expense in our condensed consolidated statement of operations for the three and nine months ended September 30, 2018, respectively. The Company used a practical expedient where the amount disclosed in our Retirement Benefits footnote for the prior year comparative period was the basis for the estimation for applying the retrospective presentation requirements. Other than this reclassification, the adoption of ASU 2017-07 did not have an impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2017-01, Business Combinations: (Topic 805): Clarifying the Definition of a Business. ASU 2017-01 is intended to clarify the definition of a business with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. We will apply the guidance of this ASU to applicable future transactions. The adoption of ASU 2017-01 did not have a material impact on the Company’s condensed consolidated financial statements. On January 1, 2018, we adopted FASB ASU 2016-16, Income Taxes: (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory and requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. We adopted this ASU using the modified retrospective method. The impact of adopting this guidance on the Company’s condensed consolidated financial statements resulted in an increase to Retained earnings of $4.1 million and Deferred income taxes of $4.7 million and a decrease to Other receivables of $0.6 million on January 1, 2018 . On January 1, 2018 , we adopted FASB ASU 2016-15, Statement of Cash Flow: (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to address eight specific cash flow issues with the objective of reducing the existing diversity in practice. Adoption of ASU 2016-15 did not have a material effect on our condensed consolidated financial statements.  On January 1, 2018, we adopted FASB ASU 2014-09, Revenue from Contracts with Customers: (Topic 606) (“ASC 606”) . This ASU replaces nearly all existing U.S. GAAP guidance on revenue recognition. The standard prescribes a five-step model for recognizing revenue, the application of which require significant judgment. We have completed our assessment and review of specific contracts and have adopted this ASU using the modified retrospective method with no impact to the opening Retained earnings balance. We expect the impact of the adoption of this ASU will not have a material effect on our consolidated financial statements on an ongoing basis.
New Accounting Standards	New Accounting Standards In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This pronouncement is effective for fiscal years beginning after December 15, 2020. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. This pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows a reclassification from Accumulated Other Comprehensive (Loss) Income to Retained Earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and requires certain disclosures about stranded tax effects. This pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 is intended to simplify the subsequent measurement of goodwill by eliminating Step 2 from the current goodwill impairment test. This pronouncement is effective for the annual or any interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019. The Company is in the process of assessing the impact that the adoption of this ASU will have on our consolidated financial statements.  In February 2016, the FASB issued ASU 2016-02, Leases: (Topic 842). ASU 2016-02 requires companies to recognize a lease liability and asset on the balance sheet for operating leases with a term greater than one year. In July 2018, the FASB issued ASU 2018-11, Targeted Improvements . This ASU provides an additional transition method to adopt the new leasing standard. Under this new transition method, an entity initially applies the new leasing standard using a cumulative-effect adjustment to the opening balance of retained earnings but will continue to report comparative periods under existing guidance in accordance with ASC 840, Leases . The amendments in ASU 2018-11 are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company has elected to adopt ASU 2016-02 using this new transition method. The Company is in the process of assessing the impact the adoption of this ASU will have on our consolidated financial statements.  No other new accounting pronouncements issued had, or are expected to have, a material impact on the Company’s consolidated financial statements.
