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 (“EMEA”) region, the United States, the Asia Pacific region, and Latin America.  Operating results for the three months ended March 31, 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 January 1, 20 18, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“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 transactions after the adoption date. The adoption of ASU 2017-09 d id not have a material impact on the Company’s condensed consolidated financial statements as of , and for the quarter ended , March 31, 2018. 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 s eparately 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 new standard 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 from Selling, general and administrative expenses to Other income, expense, net in our condensed consolidated statement of operations for the three months ended March 31, 2017. 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 d id not have an impact on the Company’s condensed consolidated financial statements as of and for the quarter ended March 31, 2018. O n 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 transactions after the adoption date. The adoption of ASU 2017-01 did not have a material impact on the Company’s condensed consolidated financial statements as of, and for the quarter ended, March 31, 2018. 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 new standard using the modified retrospective method. The impact of adopting this guidance on the Company’s condensed consolidated financial statements resulted in an increase to R etained 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 , 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 20161-15 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 a pplication of which require significant judgment. We have completed our assessment and review of specific contracts and have adopted this new standard using the modified retrospective method with no impact to the opening retained earnings balance. We expect the impact of the adoption of this new standard will not have a material effect on our consolidated financial statements on an ongoing basis .  New Accounting Standards In February 2018, the FASB issued 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. This pronouncement is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. 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 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 August 2017, the FASB issued 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. This pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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. This pronouncement is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. 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	3 Months Ended

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 revenues 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 all 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 principle 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 adoption of ASC 606.      Revenues disaggregated by geography and reportable segment for the three months ending March 31, 2018, follow:     EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 119,116 $ 12,819 $ 25,947 $ 26,766 $ 184,648  Performance Colors and Glass 61,344 37,091 16,515 5,555 120,505  Color Solutions 40,483 41,626 9,938 8,332 100,379  Total net sales $ 220,943 $ 91,536 $ 52,400 $ 40,653 $ 405,532  Revenu es disaggregated by geography and reportable segment for the three months ending March 31, 2017, follow:      EMEA United States Asia Pacific Latin America Total  (Dollars in thousands)  Performance Coatings $ 69,160 $ 10,758 $ 21,317 $ 25,330 $ 126,565  Performance Colors and Glass 44,586 39,104 14,633 5,195 103,518  Color Solutions 35,177 38,518 8,258 8,519 90,472  Total net sales $ 148,923 $ 88,380 $ 44,208 $ 39,044 $ 320,555   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 SG&A expenses.

The Credit Facility consists of a $400 million secured revolving line of credit with a term of five years, a $357.5 million secured term loan facility with a term of seven years and a €250 million secured Euro term loan facility with a term of seven years. 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 of term loans until they are fully paid and then to the revolving loans in an amount equal to a portion of the Company’s excess cash flow, as calculated pursuant to the Credit Facility. 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 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. Interest Rate – Term Loans: The interest rates applicable to the U.S. term loans will be, at the Company’s option, equal to either a base rate or a LIBOR rate plus, in both cases, an applicable margin. The interest rates applicable to the Euro term loans will be a Euro Interbank Offered Rate (“EURIBOR”) rate plus an applicable margin. · The base rate for U.S. term loans will be the highest of (i) the federal funds rate plus 0.50% , (ii) syndication agent’s prime rate or (iii) the daily LIBOR rate plus 1.00% . The applicable margin for base rate loans is 1.50% . · The LIBOR rate for U.S. term loans shall not be less than 0.75% and the applicable margin for LIBOR rate U.S. term loans is 2.50% . · The EURIBOR rate for Euro term loans shall not be less than 0% and the applicable margin for EURIBOR rate loans is 2.75% . · For LIBOR rate term loans and EURIBOR rate term loans, the Company may choose to set the duration on individual borrowings for periods of one, two, three or six months, with the interest rate based on the applicable LIBOR rate or EURIBOR rate, as applicable, for the corresponding duration. At March 31, 2018, the Company had borrowed $353.9 million under the secured term loan facility at an interest ra te of 4.38% and €247.5 million (approximately $305.1 million) under the secured Euro term loan facility at an interest rate of 2.75% . At March 31, 2018, there were no additional borrowings available under the term loan facilities. We entered into interest rate swap agreements in the second quarter of 2017. These swaps converted $150 million and €90 million of our term loans from variable interest rates to fixed interest rates. At March 31, 2018, the effective interest rate for the term loan facilities after adjusting for the interest rate swap was 4.27% for the secured term loan facility and 3.00% for the Euro term loan facility. Interest Rate – Revolving Credit Line: The interest rates applicable to loans under the revolving credit line will be, at the Company’s option, equal to either a base rate or a LIBOR rate plus, in both cases, an applicable variable margin. The variable margin will be based on the ratio of (a) the Company’s total consolidated net debt outstanding at such time to (b) the Company’s consolidated EBITDA 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 or (iii) the daily LIBOR rate plus 1.00% . The applicable margin for base rate loans will vary between 0.75% and 1.75% . · The LIBOR rate for revolving loans shall not be less than 0% and the applicable margin for LIBOR rate revolving loans will vary between 1.75% and 2.75% . · For LIBOR rate revolving loans, the Company may choose to set the duration on individual borrowings for periods of one, two, three or six months, with the interest rate based on the applicable LIBOR rate for the corresponding duration. At March 31, 201 8, there were $118.2 million borrowings under the revolving credit line at an interest rate of 4.04% . After reductions for outstanding letters of credit secured by these facilities, we had $ 277.2 million of additional borrowings available under the revolving credit facilities at March 31, 201 8. The Credit Facility contains customary restrictive covenants including, but not limited to, limitations on use of loan proceeds, limitations on the Company’s ability to pay dividends and repurchase stock, limitations on acquisitions and dispositions, and limitations on certain types of investments. The Credit Facility also contains standard provisions relating to conditions of borrowing and customary events of default, including the non-payment of obligations by the Company and the bankruptcy of the Company. Specific to the revolving credit facility, the Company is subject to a financial covenant regarding the Company’s maximum leverage ratio. If an event of default occurs, all amounts outstanding under the Credit Facility may be accelerated and become immediately due and payable. At March 31, 2018, we were in compliance with the covenants of the Credit Facility.  2014 Credit Facility In 2014, the Company entered into a credit facility that was amended on January 25, 2016 , and August 29, 2016 , resulting in a $400 million secured revolving line of credit with a term of five years and a $300 million secured term loan facility with a term of seven years from the original issuance date (the “Previous Credit Facility”) with a group of lenders that was replaced on February 14, 2017 , by the C redit Facility (as defined above ). For discussion of the Company’s Previous Credit Facility, refer to Note 8 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . In conjunction with the refinancing of the Previous Credit Facility, we recorded a charge of $3.9 million in connection with the write-off of unamortized issuance costs, which is recorded within Loss on extinguishment of debt in our condensed consolidated statement of operations for the three months ended March 31, 2017.  Other Financing Arrangements We maintain other lines of credit to provide global flexibility for our short-term liquidity requirements. These facilities are uncommitted lines for our international operations and totaled $45.6 million and $64.5 million at March 31, 2018 , and December 31, 2017 , respectively. The unused portions of these lines provided additional liquidity of $13.1 million at March 31, 2018 , and $39.4 million at December 31, 2017 .

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 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 ent er into hedging arrangements or where hedging inefficiencies exist , such as timing of transactions . Derivatives Designated as Hedging Instruments Interest rate swaps. To reduce our exposure to interest rate changes on our variable-rate debt, we entered into interest rate swap agreements in the second quarter of 2017. These swaps converted $150 million and €90 million of our term loans from variable interest rates to fixed interest rates. These swaps qualify and were designated as cash flow hedges. The effective portions of cash flow hedges are recorded in accumulated other comprehensive loss (“AOCL”) and are reclassified into earnings in the same period the underlying hedged items impact earnings. The ineffective portions of cash flow hedges is recognized immediately into earnings. The Company did not have any ineffectiveness related to the interest rate swaps during the three months ended March 31, 2018 . The amount of gain recognized in AOCL and the amount of loss reclassified into earnings for the three months ended March 31, 2018, follow:    Amount of Gain Amount of Loss Reclassified  Recognized in AOCL - from AOCL into  Effective Portion Income - Effective Portion  2018 2018  (Dollars in thousands)  Interest rate swap $ 1,709 $ (136) 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. The effective portions of net investment hedges are recorded in AOCL as a part of the cumulative translation adjustment. The ineffective portions of net investment hedges are recognized immediately into earnings. Effective May 1, 2017, the Company designated a portion of its Euro denominated debt as a net investment hedge for accounting purposes . The fair value of the net investment hedge is €19.6 million at March 31, 2018. The Company did no t have any ineffectiveness related to net investment hedges d uring the three months ended March 31, 2018 . The a mount of loss recognized in AOCL and the amount of loss reclassified into earnings for the three months ended March 31, 2018 , follow:    Amount of Loss Amount of Loss Reclassified  Recognized in AOCL - from AOCL into  Effective Portion Income - Effective Portion  2018 2018  (Dollars in thousands)  Net investment hedge $ (860) $ —  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 loss (gain) , net in the condensed consolidated statements of operations. We recognized net gains of $0.4 million in the three months ended March 31, 2018 , and net gains of $0.2 million in the three months ended March 31, 2017 , 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 $302.3 million at March 31, 2018 , and $238.5 million at December 31, 2017 . The following table presents the effect on our condensed consolidated statements of operations for the three months ended March 31, 2018 and 2017 , respectively, of our foreign currency forward contracts:      Amount of Gain  Recognized in Earnings  Three Months Ended  March 31,  2018 2017 Location of Gain in Earnings  (Dollars in thousands)  Foreign currency forward contracts $ 391 $ 243 Foreign currency loss (gain), net   Location and Fair Value Amount of Derivative Instruments  The following table presents the fair values on our condensed consolidated balance sheets of derivative instruments :      March 31, December 31,  2018 2017 Balance Sheet Location  (Dollars in thousands)  Asset derivatives:  Interest rate swaps $ 3,392 $ 1,616 Other non-current assets  Foreign currency forward contracts 804 661 Other current assets  Liability derivatives:  Interest rate swaps (191) (124) Accrued expenses and other current liabilities  Foreign currency forward contracts $ (344) $ (1,130) Accrued expenses and other current liabilities

Income Taxes [Abstract]
Income Taxes	10. Income Taxes During the first quarter of 2018, income tax expense was $7.5 million, or 24.2% of pre-tax income. In the first quarter of 2017, we recorded tax expense of $7.1 million, or 24.4% of pre-tax income. The tax expense in the first quarter of 2018, as a percentage of pre-tax income, was higher than the U.S. federal statutory income tax rate of 21% primarily as a result of foreign statutory rate differences. The tax expense for the first quarter of 2017, as a percentage of pre-tax income, was lower than the U.S. federal statutory income tax rate of 35% primarily as a result of foreign statutory rate differences.  We recognized the provisional tax impacts on our financial statements for the period ended December 31, 2017, related to the 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 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 made reasonable estimates of GILTI and FDII, as well as the impact of changes to valuation allowances related to certain positions. The combined projected 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	11. Contingent Liabilities We have recorded environmental liabilities of $6.4 m illion at March 31, 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 March 31, 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. There are various lawsuits and claims pending against the Company and its consolidated subsidiaries. We do not currently expect the resolution of these lawsuits and claims 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 22, 2013, our shareholders approved the 2013 Omnibus Incentive Plan (the “Plan”), which was adopted by the Board of Directors on February 22, 2013, 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 4,400,000 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 shares, performance shares, other common stock- based awards, and dividend equivalent rights.  In the first quarter 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 under the Plan. 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 three months ended March 31, 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 three months ended March 31, 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 . 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. The weighted-average grant date fair value per unit for grants made during the three months ended March 31, 2018 , was $22.27 . We recognized stock-based compensation expense of $2.4 million for the three months ended March 31, 2018 , and $2.7 million for the three months ended March 31, 2017 . At March 31, 2018 , unearned compensation cost related to the unvested portion of all stock-based compensation awards was approximately $11.6 million and is expected to be recognized over the remaining vesting period of the respective grants , through the first quarter of 2021 .

Recent Accounting Pronouncements [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards On January 1, 20 18, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“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 transactions after the adoption date. The adoption of ASU 2017-09 d id not have a material impact on the Company’s condensed consolidated financial statements as of , and for the quarter ended , March 31, 2018. 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 s eparately 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 new standard 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 from Selling, general and administrative expenses to Other income, expense, net in our condensed consolidated statement of operations for the three months ended March 31, 2017. 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 d id not have an impact on the Company’s condensed consolidated financial statements as of and for the quarter ended March 31, 2018. O n 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 transactions after the adoption date. The adoption of ASU 2017-01 did not have a material impact on the Company’s condensed consolidated financial statements as of, and for the quarter ended, March 31, 2018. 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 new standard using the modified retrospective method. The impact of adopting this guidance on the Company’s condensed consolidated financial statements resulted in an increase to R etained 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 , 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 20161-15 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 a pplication of which require significant judgment. We have completed our assessment and review of specific contracts and have adopted this new standard using the modified retrospective method with no impact to the opening retained earnings balance. We expect the impact of the adoption of this new standard will not have a material effect on our consolidated financial statements on an ongoing basis .
New Accounting Standards	New Accounting Standards In February 2018, the FASB issued 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. This pronouncement is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. 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 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 August 2017, the FASB issued 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. This pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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. This pronouncement is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. 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.
