Accounting Policies [Abstract]
Organization And Summary Of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies A. Organization GrafTech International Ltd. (the "Company") is one of the world’s largest manufacturers and providers of high quality graphite electrodes and needle coke. References herein to “GTI,” “we,” “our,” or “us” refer collectively to GrafTech International Ltd. and its subsidiaries. On August 15, 2015, GTI became an indirect wholly owned subsidiary of Brookfield Asset Management Inc. ("Brookfield") through a tender offer to our former shareholders and subsequent merger transaction. The Company's only reportable segment, Industrial Materials, is comprised of our two major product categories: graphite electrodes and needle coke products. Needle coke is the key raw material to producing graphite electrodes. The Industrial Materials business segment focuses on providing the highest quality graphite electrodes and providing the best customer service all while striving to be the lowest cost producer. We previously operated an Engineered Solutions business segment. See Note 2 "Discontinued Operations and Assets Held for Sale" for further information. All results from the Engineered Solutions business have been excluded from continuing operations, unless otherwise indicated. B. Basis of Presentation The interim Consolidated Financial Statements are unaudited; however, in the opinion of management, they have been prepared in accordance with Rule 10-01 of Regulation S-X and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The December 31, 2016 financial position data included herein was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “Annual Report”) but does not include all disclosures required by GAAP in audited financial statements. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the accompanying notes, contained in the Annual Report. The unaudited consolidated financial statements reflect all adjustments (all of which are of a normal, recurring nature) which management considers necessary for a fair statement of financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The results for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year. C. New Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers . This ASU supersedes the revenue recognition requirements in Accounting Standards Codification 605—Revenue Recognition and most industry-specific guidance throughout the Codification. This ASU requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU was expected to be effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years. On July 9, 2015, the FASB deferred the effective date to fiscal years beginning after December 15, 2017. During the fourth quarter of 2016, we completed the initial evaluation of the new standard and the related assessment and review of a representative sample of existing revenue contracts with our customers. We determined, on a preliminary basis, that although the timing and pattern of revenue recognition may change, the amount of revenue recognized during the year should remain substantially the same. We intend to adopt this standard using the modified retrospective method. We have begun an initiative to offer three to five year supply contracts to our strategic customers. ASU No. 2014-09 could have a material impact on the way in which we would recognize revenue under these contracts. We will continue to evaluate revenue recognition of these contracts as they are entered into. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under this new guidance, a company will now recognize most leases on its balance sheet as lease liabilities with corresponding right-of-use assets. This ASU is effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact of the adoption of this standard on its financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04 Intangibles-Goodwill and Other (Topic 350). This guidance was issued to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires that a hypothetical purchase price allocation be performed to determine the amount of impairment, if any. Under this new guidance, a goodwill impairment charge will be based on the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance will become effective on a prospective basis for the Company on January 1, 2020 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of the adoption of this standard on its results of operations. In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). This standard requires an entity to report the service cost component in the same line item as other compensation costs. The other components of net (benefit) cost including our annual mark-to-market re-measurement, will be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This standard is effective for interim and annual reporting periods beginning after December 15, 2017. The components of the net (benefit) cost are shown in Note 4, "Benefit Plans."

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations and Related Assets Held for Sale On February 26, 2016, the Company announced that it had initiated a strategic review of its Engineered Solutions business segment to better direct its resources and simplify its operations. Any potential sale of assets was prohibited by the Revolving Facility without approval of the requisite lenders thereunder. On April 27, 2016, GrafTech and certain of its subsidiaries entered into an amendment to the Revolving Facility (see Note 6 "Debt and Liquidity") which, among other things, permits the sale of assets with the restriction that the proceeds be utilized to pay down revolver borrowings. As of June 30, 2016, the Engineered Solutions segment qualified for reporting as discontinued operations as its divestiture represents a strategic shift for the Company. During 2016, we evaluated the fair value of the Engineered Solutions business segment utilizing the market approach (Level 3 measure). As a result, we incurred an impairment charge to our Engineered Solutions business segment of $120 million to align the carrying value with estimated fair value. We continued to update this estimate and during the nine months ended September 30, 2017, we further reduced the estimated fair value by $5.3 million based upon current information. On November 30, 2016, we completed the sale of our Fiber Materials Inc. business, which was a business line within our former Engineered Solutions business. The sale resulted in cash proceeds of $15.9 million and a loss of $0.2 million . We have the ability to realize up to $8.5 million of additional proceeds based on the earnings of the Fiber Materials business over the 24 months following the transaction. We have elected to record this contingent consideration as it is realized and as such, it is not recognized thus far on the transaction. On July 3, 2017 we completed the sale of our Advanced Energy Technologies (AET) business. AET was a product line within our Engineered Solutions business which had been classified as held for sale since the second quarter of 2016. The sale resulted in cash proceeds of $28.5 million . On September 30, 2017, we completed the sale of the majority of the U.S. assets of our GrafTech Advanced Graphite Materials (GAGM) business, which was a component of our Engineered Solutions business. The sale of the Italian GAGM assets closed on October 5, 2017. In the jurisdictions where the GAGM assets were not acquired, we initiated the wind-down of the business which we expect to be substantially completed by year-end. The sale was structured as a non-cash transaction with the buyer assuming certain liabilities associated with the assets acquired. In addition, GrafTech retained certain current assets of GAGM, mostly receivables, which will be substantially realized in the course of the 4th quarter of 2017. As such, the disposition of the GAGM assets did not result in any cash proceeds in the third quarter of 2017. As a result of the sales described above, we recorded a gain of $3.7 million in the third quarter of 2017. The disposition of the Engineered Solutions business is now substantially complete, with only the wind-down in the fourth quarter of 2017 remaining. In accordance with our Credit Facility, all cash proceeds from these sales were used to pay down our Revolving Facility and Term Loan. The following tables summarize the results of the Engineered Solutions business segment, reclassified as discontinued operations for the three and nine months ended September 30, 2016 and 2017 .

Segment Reporting Information, Revenue for Reportable Segment [Abstract]
Segment Reporting	Segment Reporting We previously operated two reportable business segments, Industrial Materials and Engineered Solutions. During 2016 the Company decided to sell the businesses that comprised our Engineered Solutions segment to focus on our Industrial Materials segment. During the second quarter of 2016 the Engineered Solutions segment qualified as held for sale status and as such the related results have been excluded from continuing operations. See Note 2 "Discontinued Operations and Assets Held for Sale" for significant components of the results of our Engineered Solutions segment. Our Industrial Materials segment manufactures and delivers high quality graphite electrodes and needle coke products. Electrodes are key components of the conductive power systems used to produce steel and other non-ferrous metals. Needle coke, a crystalline form of carbon derived from decant oil, is the key ingredient in, and is used primarily in, the production of graphite electrodes.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Other Intangible Assets	Goodwill and Other Intangible Assets We are required to review goodwill and indefinite-lived intangible assets annually for impairment. Goodwill impairment is tested at the graphite electrodes reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The following tables represent the changes in the carrying value of goodwill and intangibles for the nine months ended September 30, 2017 : Goodwill Balance as of December 31, 2016 $ 171,117 Adjustments — Balance as of September 30, 2017 $ 171,117 Intangible Assets As of December 31, 2016 As of September 30, 2017 Gross Carrying Amount Accumulated Net Carrying Amount Gross Carrying Amount Accumulated Amortization & Impairment Net Carrying Amount (Dollars in Thousands) Trade name $ 22,500 $ (3,235 ) $ 19,265 $ 22,500 $ (4,954 ) $ 17,546 Technological know-how 55,300 (10,397 ) 44,903 55,300 (15,646 ) 39,654 Customer –related intangible 64,500 (6,177 ) 58,323 64,500 (9,527 ) 54,973 Total finite-lived intangible assets $ 142,300 $ (19,809 ) $ 122,491 $ 142,300 $ (30,127 ) $ 112,173 Amortization expense of acquired intangible assets was $3.5 million and $10.7 million in the three and nine months ended September 30, 2016 and $3.4 million and $10.3 million in the three and nine months ended September 30, 2017 .

As a result of our acquisition by Brookfield and the resulting purchase price accounting adjustments, our Senior Notes were adjusted to their fair market value as of August 15, 2015. The discount to fair value will be accreted over the remaining term of the Notes. Credit Facility On April 23, 2014, the Company and certain of its subsidiaries entered into an Amended and Restated Credit Agreement with a borrowing capacity of $400 million and a maturity date of April 2019 (the "Revolving Facility"). On February 27, 2015, GrafTech and certain of its subsidiaries entered into a further Amended and Restated Credit Agreement that provides for, among other things, greater financial flexibility and a $40 million senior secured delayed draw term loan facility (the "Term Loan Facility"). On July 28, 2015, GrafTech and certain of its subsidiaries entered into an amendment to the Amended and Restated Credit Agreement to change the terms regarding the occurrence of a default upon a change in control (which is defined thereunder to include the acquisition by any person of more than 25 percent of GrafTech’s outstanding shares) to exclude the acquisition of shares by Brookfield. In addition, effective upon such acquisition, the financial covenants were eased, resulting in increased availability under the Revolving Facility. The size of the Revolving Facility was also reduced from $400 million to $375 million . The size of the Term Loan Facility remained at $40 million . On April 27, 2016 , GrafTech and certain of its subsidiaries entered into an amendment to the Revolving Facility. The size of the Revolving Facility was permanently reduced from $375 million to $225 million . New covenants were also added to the Revolving Facility, including a requirement to make mandatory repayments of outstanding amounts under the Revolving Facility and the Term Loan Facility with the proceeds of any sale of all or any substantial part of the assets included in the Engineered Solutions segment and a requirement to maintain minimum liquidity (consisting of domestic cash, cash equivalents and availability under the Revolving Facility) in excess of $25 million . The covenants were also modified to provide for: the elimination of certain exceptions to the Company’s negative covenants limiting the Company’s ability to make certain investments, sell assets, make restricted payments, incur liens, incur debt and prepay or redeem other indebtedness; a restriction on the amount of cash and cash equivalents permitted to be held on the balance sheet at any one time without paying down the Revolving Facility and the Term Loan Facility; and changes to the Company’s financial covenants so that until the earlier of March 31, 2019 or the Company has $75 million in trailing twelve month EBITDA (as defined in the Revolving Facility), the Company is required to maintain trailing twelve month EBITDA above certain minimums ranging from ( $40 million ) to $35 million after which the Company’s existing financial covenants under the Revolving Facility will apply. With this amendment, the Company has full access to the $225 million Revolving Facility, subject to the $25 million minimum liquidity requirement. As of September 30, 2017 , the Company had $35.3 million of borrowings on the Revolving Facility and $11.6 million of letters of credit drawn against the Revolving Facility. The $40 million Term Loan Facility was fully drawn on August 11, 2015, in connection with the repayment of the Senior Subordinated Notes. The balance of the Term Loan Facility was $18.8 million as of September 30, 2017 . The interest rate applicable to the Revolving Facility and Term Loan Facility is LIBOR plus a margin ranging from 2.25% to 4.75% (depending on our total senior secured leverage ratio). The borrowers pay a per annum fee ranging from 0.35% to 0.70% (depending on our senior secured leverage ratio) on the undrawn portion of the commitments under the Revolving Facility. Senior Notes On November 20, 2012, the Company issued $ 300 million principal amount of 6.375% Senior Notes due 2020 (the "Senior Notes"). The Senior Notes are the Company's senior unsecured obligations and rank pari passu with all of the Company's existing and future senior unsecured indebtedness. The Senior Notes are guaranteed on a senior unsecured basis by each of the Company's existing and future subsidiaries that guarantee certain other indebtedness of the Company or another guarantor. The Senior Notes bear interest at a rate of 6.375% per year, payable semi-annually in arrears on May 15 and November 15 of each year. The Senior Notes mature on November 15, 2020. The Company is entitled to redeem some or all of the Senior Notes at any time on or after November 15, 2016, at the redemption prices set forth in the indenture. The indenture for the Senior Notes states that if, prior to maturity, a change in control (as defined in the indenture) of the Company occurs and thereafter certain downgrades of the ratings of the Senior Notes as specified in the indenture occur, the Company will be required to offer to repurchase any or all of the Senior Notes at a repurchase price equal to 101% of the aggregate principal amount of the Senior Notes, plus any accrued and unpaid interest. On August 17, 2015, a change in control occurred due to the Merger. However, the downgrade of the ratings of the Senior Notes, as specified in the indenture, did not occur. Therefore, the Company was not required to offer to repurchase the Senior Notes as a result of the Merger. The indenture for the Senior Notes also contains covenants that, among other things, limit the ability of the Company and certain of its subsidiaries to: (i) create liens or use assets as security in other transactions; (ii) engage in certain sale/leaseback transactions; and (iii) merge, consolidate or sell, transfer, lease or dispose of substantially all of their assets. The indenture for the Senior Notes also contains customary events of default, including (i) failure to pay principal or interest on the Senior Notes when due and payable, (ii) failure to comply with covenants or agreements in the indenture or the Senior Notes which failures are not cured or waived as provided in the indenture, (iii) failure to pay indebtedness of the Company, any Subsidiary Guarantor or Significant Subsidiary (each, as defined in the indenture) within any applicable grace period after maturity or acceleration and the total amount of such indebtedness unpaid or accelerated exceeds $ 50.0 million , (iv) certain events of bankruptcy, insolvency, or reorganization, (v) failure to pay any judgment or decree for an amount in excess of $ 50.0 million against the Company, any Subsidiary Guarantor or any Significant Subsidiary that is not discharged, waived or stayed as provided in the indenture, (vi) cessation of any Subsidiary Guarantee (as defined in the indenture) to be in full force and effect or denial or disaffirmance by any subsidiary guarantor of its obligations under its subsidiary guarantee, and (vii) a default under the Company's Senior Subordinated Notes. In the case of an event of default, the principal amount of the Senior Notes plus accrued and unpaid interest may be accelerated.

Loss Contingency [Abstract]
Contingencies	Contingencies Legal Proceedings We are involved in various investigations, lawsuits, claims, demands, environmental compliance programs and other legal proceedings arising out of or incidental to the conduct of our business. While it is not possible to determine the ultimate disposition of each of these matters, we do not believe that their ultimate disposition will have a material adverse effect on our financial position, results of operations or cash flows. Litigation has been pending in Brazil brought by employees seeking to recover additional amounts under certain wage increase provisions applicable in 1989 and 1990 under collective bargaining agreements to which employers in the Bahia region of Brazil were a party (including our subsidiary in Brazil), plus interest thereon. Prior to October 1, 2015, we were not party to such litigation. Companies in Brazil have recently settled claims arising out of these provisions and, in May 2015, the litigation was remanded, in favor of the employees, by the Brazil Supreme Court to the lower courts for further proceedings which included procedural aspects of the case, such as admissibility of instruments filed by the parties. We cannot predict the outcome of such litigation. On October 1, 2015, an action was filed by current and former employees against our subsidiary in Brazil to recover amounts under such provisions, plus interest thereon, which amounts together with interest could be material to us. In the 1 st quarter 2017, this case was ruled in favor of the employees at the state court level. The Company has appealed and intends to vigorously defend itself. The claims specify neither the employees covered nor the amount of damages sought, therefore a range of potential losses cannot be estimated. Product Warranties We generally sell products with a limited warranty. We accrue for known warranty claims if a loss is probable and can be reasonably estimated. We also accrue for estimated warranty claims incurred based on a historical claims charge analysis. Claims accrued but not yet paid and the related activity within the accrual for the nine months ended September 30, 2017 , are presented below: (Dollars in thousands) Balance as of December 31, 2016 $ 969 Product warranty adjustments (210 ) Accruals and Payments (290 ) Balance as of September 30, 2017 $ 469

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We compute and apply to ordinary income an estimated annual effective tax rate on a quarterly basis based on current and forecasted business levels and activities, including the mix of domestic and foreign results and enacted tax laws. The estimated annual effective tax rate is updated quarterly based on actual results and updated operating forecasts. Ordinary income refers to income (loss) before income tax expense excluding significant, unusual, or infrequently occurring items. The tax effect of an unusual or infrequently occurring item is recorded in the interim period in which it occurs as a discrete item of tax. The following tables summarize the provision for income taxes for the three and nine months ended September 30, 2016 and September 30, 2017 : For the Three Months Ended September 30, For the Nine Months 2016 2017 2016 2017 (Dollars in thousands) Tax (benefit) expense $ (1,789 ) $ 1,963 $ (7,675 ) $ 3,249 Pretax loss (25,890 ) (5,190 ) (87,847 ) (39,515 ) Effective tax rates 6.9 % (37.8 )% 8.7 % (8.2 )% For the three and nine months ended September 30, 2016 and 2017 the effective tax rate differs from the U.S. statutory rate of 35% primarily due to recent losses in the U.S. and Switzerland where we receive no tax benefit due to a full valuation allowance and worldwide earnings from various countries taxed at different rates. The recognition of the valuation allowance does not result in or limit the Company's ability to utilize these tax assets in the future. As of September 30, 2017 , we had unrecognized tax benefits of $2.6 million , $2.3 million of which, if recognized, would have a favorable impact on our effective tax rate. We file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. All U.S. federal tax years prior to 2014 are generally closed by statute or have been audited and settled with the applicable domestic tax authorities. All other jurisdictions are still open to examination beginning after 2010. We continue to assess the realization of our deferred tax assets based on determinations of whether it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. Examples of positive evidence would include a strong earnings history, an event or events that would increase our taxable income through a continued reduction of expenses, and tax planning strategies that would indicate an ability to realize deferred tax assets. In circumstances where the significant positive evidence does not outweigh the negative evidence in regards to whether or not a valuation allowance is required, we have established and maintained valuation allowances on those net deferred tax assets.

Derivative Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments We use derivative instruments as part of our overall foreign currency and commodity risk management strategies to manage the risk of exchange rate movements that would reduce the value of our foreign cash flows and to minimize commodity price volatility. Foreign currency exchange rate movements create a degree of risk by affecting the value of sales made and costs incurred in currencies other than the U.S. dollar. Certain of our derivative contracts contain provisions that require us to provide collateral. Since the counterparties to these financial instruments are large commercial banks and similar financial institutions, we do not believe that we are exposed to material counterparty credit risk. We do not anticipate nonperformance by any of the counter-parties to our instruments. Our derivative risk management strategy has not resulted in a material impact to our financial results in 2016 or 2017. Our derivative assets and liabilities are included within "Prepaid expenses and other current assets" and "Other current liabilities" on the Condensed Consolidated Balance Sheets and effects of these derivatives are recorded in revenue, cost of goods sold and other expense (income) on the Condensed Consolidated Statements of Operations. Foreign currency derivatives We enter into foreign currency derivatives from time to time to attempt to manage exposure to changes in currency exchange rates. These foreign currency instruments, which include, but are not limited to, forward exchange contracts and purchased currency options, attempt to hedge global currency exposures such as foreign currency denominated debt, sales, receivables, payables, and purchases. Forward exchange contracts are agreements to exchange different currencies at a specified future date and at a specified rate. There was no ineffectiveness on these contracts designated as hedging instruments during the nine months ended September 30, 2016 and 2017 , respectively. In 2016 and 2017 , we entered into foreign currency derivatives denominated in the Mexican peso, South African rand, Brazilian real, euro and Japanese yen. These derivatives were entered into to protect the risk that the eventual cash flows resulting from commercial and business transactions may be adversely affected by changes in exchange rates between the U.S. dollar and the Mexican peso, euro, South African rand and Japanese yen. As of September 30, 2017 , we had outstanding Mexican peso, euro, and Japanese yen currency contracts with an aggregate notional amount of $18.8 million . The foreign currency derivatives outstanding as of September 30, 2017 , have maturities through December 29, 2017 . Commodity derivative contracts We periodically enter into derivative contracts for certain refined oil products and natural gas. These contracts are entered into to protect against the risk that eventual cash flows related to these products may be adversely affected by future changes in prices. As of September 30, 2017 , we had no outstanding derivative swap contracts for refined oil products or natural gas. Net Investment Hedges We use certain intercompany debt to hedge a portion of our net investment in our foreign operations against currency exposure (net investment hedge). Intercompany debt denominated in foreign currency and designated as a non-derivative net investment hedging instrument was $13.3 million and $13.5 million as of December 31, 2016 and September 30, 2017 , respectively. Within the currency translation adjustment portion of other comprehensive income, we recorded losses of $0.9 million and $1.5 million for the three and nine months ended September 30, 2016 , respectively. We incurred a gain of $0.5 million and a loss of $0.2 million in the three and nine months ended September 30, 2017 , respectively, resulting from these net investment hedges.

Consolidating Financials [Abstract]
Supplemental Guarantor Information	Guarantor Information On November 20, 2012, GrafTech International Ltd. (the “Parent”) issued $300 million aggregate principal amount of Senior Notes. The Senior Notes mature on November 15, 2020 and bear interest at a rate of 6.375% per year, payable semi-annually in arrears on May 15 and November 15 of each year. The Senior Notes are guaranteed on a senior basis by the following wholly-owned direct and indirect subsidiaries of the Parent: GrafTech Finance Inc., GrafTech Holdings Inc., GrafTech USA LLC, Seadrift Coke LP, GrafTech Global Enterprises Inc., GrafTech International Holdings Inc., GrafTech DE LLC, GrafTech Seadrift Holding Corp, GrafTech Technology LLC, GrafTech NY Inc., and Graphite Electrode Network LLC. The guarantors of the Senior Notes, solely in their respective capacities as such, are collectively called the “Guarantors.” Our other subsidiaries, which are not guarantors of the Senior Notes, are called the “Non-Guarantors.” All of the guarantees are unsecured. All of the guarantees are full, unconditional (subject to limited exceptions described below) and joint and several. Each of the Guarantors are 100% owned, directly or indirectly, by the Parent. All of the guarantees of the Senior Notes continue until the Senior Notes have been paid in full, and payment under such guarantees could be required immediately upon the occurrence of an event of default under the Senior Notes. If a Guarantor makes a payment under its guarantee of the Senior Notes, it would have the right under certain circumstances to seek contribution from the other Guarantors. The Guarantors will be released from the guarantees upon the occurrence of certain events, including the following: the unconditional release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the Senior Notes by such Guarantor; the sale or other disposition, including by way of merger or consolidation or the sale of its capital stock, following which such Guarantor is no longer a subsidiary of the Parent; or the Parent's exercise of its legal defeasance option or its covenant defeasance option as described in the indenture applicable to the Senior Notes. If any Guarantor is released, no holder of the Senior Notes will have a claim as a creditor against such Guarantor. The indebtedness and other liabilities, including trade payables and preferred stock, if any, of each Guarantor are effectively senior to the claim of any holders of the Senior Notes. Investments in subsidiaries are recorded on the equity basis.

Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation The interim Consolidated Financial Statements are unaudited; however, in the opinion of management, they have been prepared in accordance with Rule 10-01 of Regulation S-X and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The December 31, 2016 financial position data included herein was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “Annual Report”) but does not include all disclosures required by GAAP in audited financial statements. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the accompanying notes, contained in the Annual Report. The unaudited consolidated financial statements reflect all adjustments (all of which are of a normal, recurring nature) which management considers necessary for a fair statement of financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The results for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers . This ASU supersedes the revenue recognition requirements in Accounting Standards Codification 605—Revenue Recognition and most industry-specific guidance throughout the Codification. This ASU requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU was expected to be effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years. On July 9, 2015, the FASB deferred the effective date to fiscal years beginning after December 15, 2017. During the fourth quarter of 2016, we completed the initial evaluation of the new standard and the related assessment and review of a representative sample of existing revenue contracts with our customers. We determined, on a preliminary basis, that although the timing and pattern of revenue recognition may change, the amount of revenue recognized during the year should remain substantially the same. We intend to adopt this standard using the modified retrospective method. We have begun an initiative to offer three to five year supply contracts to our strategic customers. ASU No. 2014-09 could have a material impact on the way in which we would recognize revenue under these contracts. We will continue to evaluate revenue recognition of these contracts as they are entered into. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under this new guidance, a company will now recognize most leases on its balance sheet as lease liabilities with corresponding right-of-use assets. This ASU is effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact of the adoption of this standard on its financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04 Intangibles-Goodwill and Other (Topic 350). This guidance was issued to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires that a hypothetical purchase price allocation be performed to determine the amount of impairment, if any. Under this new guidance, a goodwill impairment charge will be based on the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance will become effective on a prospective basis for the Company on January 1, 2020 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of the adoption of this standard on its results of operations. In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). This standard requires an entity to report the service cost component in the same line item as other compensation costs. The other components of net (benefit) cost including our annual mark-to-market re-measurement, will be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This standard is effective for interim and annual reporting periods beginning after December 15, 2017. The components of the net (benefit) cost are shown in Note 4, "Benefit Plans."

Income Tax Disclosure [Abstract]
Summary Of Provision For Income Taxes	Income Taxes We compute and apply to ordinary income an estimated annual effective tax rate on a quarterly basis based on current and forecasted business levels and activities, including the mix of domestic and foreign results and enacted tax laws. The estimated annual effective tax rate is updated quarterly based on actual results and updated operating forecasts. Ordinary income refers to income (loss) before income tax expense excluding significant, unusual, or infrequently occurring items. The tax effect of an unusual or infrequently occurring item is recorded in the interim period in which it occurs as a discrete item of tax. The following tables summarize the provision for income taxes for the three and nine months ended September 30, 2016 and September 30, 2017 : For the Three Months Ended September 30, For the Nine Months 2016 2017 2016 2017 (Dollars in thousands) Tax (benefit) expense $ (1,789 ) $ 1,963 $ (7,675 ) $ 3,249 Pretax loss (25,890 ) (5,190 ) (87,847 ) (39,515 ) Effective tax rates 6.9 % (37.8 )% 8.7 % (8.2 )% For the three and nine months ended September 30, 2016 and 2017 the effective tax rate differs from the U.S. statutory rate of 35% primarily due to recent losses in the U.S. and Switzerland where we receive no tax benefit due to a full valuation allowance and worldwide earnings from various countries taxed at different rates. The recognition of the valuation allowance does not result in or limit the Company's ability to utilize these tax assets in the future. As of September 30, 2017 , we had unrecognized tax benefits of $2.6 million , $2.3 million of which, if recognized, would have a favorable impact on our effective tax rate. We file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. All U.S. federal tax years prior to 2014 are generally closed by statute or have been audited and settled with the applicable domestic tax authorities. All other jurisdictions are still open to examination beginning after 2010. We continue to assess the realization of our deferred tax assets based on determinations of whether it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. Examples of positive evidence would include a strong earnings history, an event or events that would increase our taxable income through a continued reduction of expenses, and tax planning strategies that would indicate an ability to realize deferred tax assets. In circumstances where the significant positive evidence does not outweigh the negative evidence in regards to whether or not a valuation allowance is required, we have established and maintained valuation allowances on those net deferred tax assets.
