Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation and Consolidation The consolidated financial statements have been prepared on the basis of U.S. generally accepted accounting principles ("U.S. GAAP"). The consolidated financial statements include the accounts of Xerium Technologies, Inc. and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. Revenue Recognition Revenue on product sales is recognized when persuasive evidence of an arrangement exists, the price is fixed and determinable, delivery including transfer of title has occurred and there is a reasonable assurance of collection of the sales proceeds. The Company generally obtains written purchase authorizations from customers for a specific product or service at a specified price and considers delivery and transfer of title to have occurred in accordance with our shipping terms. Revenue is recorded net of applicable allowances, including estimated allowances for returns, rebates and other discounts. In the machine clothing segment, a small portion of the business has been conducted pursuant to consignment arrangements under which the Company does not recognize a sale of a product to a customer until the customer places the product into use, which typically occurs some period after the product is shipped to the customer or to a warehouse location near the customer’s facility. As part of the consignment agreement, the Company delivers the goods to a location designated by the customer. In addition, the customer and the Company agree to a “sunset” date, which represents the date by which the customer must accept all risks and rewards of ownership of the product and payment terms begin. For consignment sales, revenue is recognized on the earlier of the actual product installation date or the “sunset” date. Classification of Costs and Expenses Cost of products sold includes raw materials, manufacturing labor, direct and indirect overhead costs, product freight, and depreciation of manufacturing plant and equipment. Warehousing costs incurred as a result of customer-specific delivery terms are also included in cost of products sold. Selling expenses include direct sales force salaries, commissions, travel and entertainment expenses and other expenses as well as agents’ commissions and fees, other warehousing costs, advertising costs and marketing costs. General and administrative expenses include costs relating to management and administrative staff such as employee compensation and benefits, travel and entertainment (non-sales), non-manufacturing facility occupancy costs, including rent expense and professional fees, as well as depreciation on non-manufacturing equipment and office supplies and expenses. Research and development expenses are comprised of engineering staff wages and associated fringe benefits, as well as the cost of prototypes, testing materials and non-capitalizable testing equipment. Advertising Costs Selling expenses include advertising expenses of $0.9 million , $1.1 million and $1.2 million in 2017 , 2016 and 2015 , respectively. The Company expenses all advertising costs as incurred. Translation of Financial Statements The reporting currency of the Company is U.S. Dollars. Assets and liabilities of non-U.S. operations are translated at year-end rates of exchange and the Consolidated Statements of Operations and Cash Flows are translated at the average rates of exchange during the year. Gains and losses resulting from translating non-U.S. Dollar denominated financial statements are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ deficit. Foreign Exchange Foreign exchange gains and losses arising out of transactions denominated in currencies other than a subsidiary’s functional currency are recorded in the Consolidated Statements of Operations. Net foreign exchange gains and losses are recorded in “Foreign exchange (loss) gain” and amounted to a (loss) gain of $(2,942) , $(383) and $1,872 for the years ended December 31, 2017 , 2016 and 2015 , respectively. Certain intercompany loans have been determined to be permanent, and accordingly, foreign exchange gains or losses related to such loans are recorded in accumulated other comprehensive loss within equity. Derivatives and Hedging As required by ASC Topic 815, Derivatives and Hedging (“Topic 815”), the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has not elected hedge accounting for any of its hedging activities. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting under Topic 815. See Note 6 "Derivatives and Hedging" for further discussion on the Company’s derivatives. Freight Costs The Company incurred $11.2 million , $10.3 million and $10.2 million in freight costs in the years ended December 31, 2017 , 2016 and 2015 , respectively. These costs are includes in cost of good sold in the Consolidated Income Statements. Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with maturities of three months or less when acquired. Short-term investments consist of time deposits or money market accounts at investment-grade banks. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at cost and do not bear interest. Bad debt provisions are included in general and administrative expense. The amounts recorded are derived based upon the general aging of receivables, specific customer credit history and payment trends and new business conditions. Inventories Inventories are generally valued at the lower of cost or market using the first-in, first-out ("FIFO") method. Raw materials are valued principally on a weighted average cost basis. The Company’s work in process and finished goods are specifically identified and valued based on actual inputs to production. Provisions are recorded as appropriate to write-down obsolete and excess inventory to estimated net realizable value. The process for evaluating obsolete and excess inventory often requires management to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be able to be sold in the normal course of business, while considering the general aging of inventory and factoring in any new business conditions. The components of inventories are as follows at: December 31, 2017 2016 Raw materials $ 13,881 $ 14,089 Work in process 27,819 25,879 Finished goods (includes consigned inventory of $7,757 in 2017 and $6,673 in 2016) 39,798 37,155 Inventory allowances (6,773 ) (6,301 ) $ 74,725 $ 70,822 Financial Instruments The carrying value of cash and cash equivalents, trade receivables, other current assets, accounts payable, notes payable and amounts included in accruals meeting the definition of a financial instrument under U.S. GAAP approximate fair value due to their short-term nature. The carrying value of long-term debt is less than its fair value (see Note 5 "Long-term Debt"). The Company determines estimated fair values based upon quoted market values where applicable or management estimates. Long-lived Assets Property and equipment Property and equipment are recorded at cost. Property and equipment acquired in connection with acquisitions are recorded at fair value as of the date of the acquisition, and subsequent additions are recorded at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: Asset Years Buildings and improvements 3-50 Machinery and equipment — Heavy 16-25 — General 13-15 — Light 6-12 — Molds, tools, office and computers 2-5 Property and equipment consist of the following at: December 31, 2017 2016 Land $ 22,072 $ 21,323 Building and improvements 155,566 142,435 Machinery and equipment 659,641 610,586 Construction in progress 7,493 6,827 Assets under capital lease 20,742 19,605 Total 865,514 800,776 Less accumulated depreciation (583,136 ) (516,675 ) $ 282,378 $ 284,101 The Company recorded $31.7 million , $32.1 million and $29.0 million in depreciation expense in 2017 , 2016 and 2015 , respectively. Amortization related to assets under capital lease is included in depreciation expense. Assets held for sale or sold During the first quarter of 2016, the Company determined that the Middletown, VA. facility, with a NBV of $3.0 million met the criteria under ASC Topic 360, Property, Plant, and Equipment (“Topic 360”) to be classified as held for sale. Accordingly, the related assets were reclassified out of property, plant and equipment to other assets in the Company's Consolidated Balance Sheet. This facility had not been sold as of December 31, 2017. During 2015, the Company determined that the Warwick, Quebec, Canada machine clothing facility, with a NBV of $0.5 million met the criteria under ASC Topic 360, Property, Plant, and Equipment (“Topic 360”) to be classified as held for sale. This facility had not been sold as of December 31, 2017. During 2013, a rolls facility in Charlotte, NC was classified as held for sale. This property had a carrying value of $0.5 million . Accordingly, the related assets were reclassified out of property, plant and equipment to other assets in the Company's Consolidated Balance Sheet. This facility was sold during 2017. Impairment The Company reviews its long-lived assets that have finite lives for impairment in accordance with Topic 360. This topic requires that companies evaluate the fair value of long-lived assets based on the anticipated un-discounted future cash flows to be generated by the assets when indicators of impairment exist to determine if there is impairment to the carrying value. Any change in the carrying amount of an asset as a result of the Company’s evaluation has been recorded as a component of income from operations in the Consolidated Statements of Operations. Impairment charges associated with restructuring are discussed in Note 11 "Restructuring Expense". Intangible assets Intangible assets consist of patents, licenses, trademarks, and customer relationships. Patents, licenses, trademarks, and customer relationships are amortized on a straight-line basis over their useful lives, which range from seven to fifteen years. Goodwill The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, Intangibles—Goodwill and Other Intangible Assets (“Topic 350”). Topic 350 requires that goodwill and intangible assets that have indefinite lives not be amortized but, instead, must be tested at least annually for impairment or whenever events or business conditions warrant. The Company first assessed qualitative factors to determine whether it was more likely than not that the fair value of its reporting units were less than the carrying amounts as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company’s assessment is that the two-step goodwill impairment test was not necessary for the year ending December 31, 2017 and 2016 for either its clothing or rolls reporting units. If the qualitative factors had indicated that it was more likely than not that the fair value of the reporting units was less than its carrying amount, the Company would have tested goodwill for impairment at the reporting unit level using a two-step approach. Step 1 involves comparing the fair value of the Company’s reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit carrying amount is greater than the fair value then the second step must be completed to measure the amount of impairment, if any. Step 2 calculates the implied fair value of goodwill by deducting the fair value of the net assets of the reporting unit from the fair value of the reporting unit as determined in Step 1. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference. The Company performs an annual test for goodwill impairment as of October 1 at the reporting unit level. The Company has two reporting units: machine clothing and roll covers. For the purpose of performing the annual impairment test, the Company allocates all shared assets and liabilities to the reporting units based on the percentage of each reporting unit’s revenue to total revenue. Shared operating expenses are allocated to the reporting unit to the extent necessary to allow them to operate as independent businesses. To determine if impairment exists, the fair value of each reporting unit is compared to its carrying value. The fair value of the Company’s reporting unit is determined by using a weighted combination of both a market multiple approach and an income approach. The market multiple approach utilizes the Company’s and its competitors’ proprietary information that is used to value its reporting units. The income approach is a present value technique used to measure the fair value of future cash flows produced by each reporting unit. During the fourth quarter of 2016, the Company voluntarily changed the date of its annual goodwill impairment testing from December 31, the last day of the fiscal year, to October 1. The voluntary change in accounting principle related to the annual testing date did not delay, accelerate or avoid an impairment charge. This change was not applied retrospectively, as it would have required application of significant estimates and assumptions with the use of hindsight. Accordingly, the change was applied prospectively. As a result of the annual tests for goodwill impairment performed as of October 1, 2017 and October 1, 2016 , the Company determined that no goodwill impairment exists. Stock-Based Compensation The Company records stock-based compensation expense in accordance with ASC Topic 718, Compensation—Stock Compensation (“Topic 718”) which generally requires that such transactions be recognized in the statement of operations based on their fair values at the date of grant. See Note 10 "Long-term Incentive and Stock-Based Compensation" for further discussion. Net (Loss) Income Per Common Share Net (loss) income per common share has been computed and presented pursuant to the provisions of ASC Topic 260, Earnings per Share (“Topic 260”). Net (loss) income per share is based on the weighted-average number of shares outstanding during the period. As of December 31, 2017 , 2016 and 2015 , the Company had outstanding restricted stock units (“RSUs”) (See Note 10 "Long-term Incentive and Stock-Based Compensation"). Diluted average shares outstanding were computed using (i) the average market price for time-based RSUs and (ii) the actual grant date market price for non-employee director RSUs. The calculation of diluted earnings per share excludes the Company’s performance-based RSUs that are based on Adjusted EBITDA targets whose performance criteria have not been contingently achieved and therefore the RSUs have not been issued or are not contingently issuable. For the years ended December 31, 2017 , 2016 , and 2015 the dilutive effect of potential future issuances of common stock underlying the Company’s RSUs was excluded from the calculation of diluted average shares outstanding because their effect would have been anti-dilutive as the Company incurred a net loss. 2017 2016 2015 Weighted-average common shares outstanding—basic 16,282,536 15,994,467 15,640,836 Dilutive effect of stock-based compensation awards outstanding — — — Weighted-average common shares outstanding—diluted 16,282,536 15,994,467 15,640,836 Dilutive securities aggregating approximately 1.0 million , 0.9 million and 1.1 million outstanding during the years ended December 31, 2017 , 2016 and 2015 , respectively, were not included in the computation of diluted earnings per share because the impact would be anti-dilutive to the earnings per share calculation . Income Taxes The Company accounts for income taxes in accordance with ASC Topic 740 , Income Taxes (“Topic 740”), which requires the recognition of deferred tax assets and liabilities for the expected future consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets, representing future tax benefits, are reduced by a valuation allowance when the determination can be made that it is “more likely than not” that all or a portion of the related tax asset will not be realized. The deferred tax provision or benefit represents the annual change in deferred tax assets and liabilities, excluding any amounts accounted for as components of goodwill or accumulated other comprehensive loss, including the effect of foreign currency translation thereon. While the Company believes it has adequately provided for its income tax receivable or liabilities and its deferred tax assets or liabilities in accordance with Topic 740 income tax guidance, adverse determination by taxing authorities or changes in tax laws and regulations could have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. Income taxes are further discussed in Note 7. Warranties The Company offers warranties on certain rolls products that it sells. The specific terms and conditions of these warranties vary depending on the product sold, the country in which the product is sold and arrangements with the customer. The Company estimates the costs that may be incurred under its warranties and records a liability for such costs. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction. The Company periodically assesses the adequacy of its recorded warranty claims and adjusts the amounts as necessary. The table below represents the changes in the Company’s warranty liability included in accrued expenses for 2017 and 2016 : Balance at Beginning of Year Charged to Cost of Products Sold Effect of Foreign Currency Translation Deduction from Reserves Balance at End of Year For the year ended December 31, 2017 $ 2,203 $ 1,202 $ 75 $ (1,010 ) $ 2,470 For the year ended December 31, 2016 $ 2,175 $ 1,616 $ 26 $ (1,614 ) $ 2,203 Commitments and Contingencies The Company provides accruals for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. Costs accrued have been estimated based on consultation with legal counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Acquisitions Acquired businesses are accounted for using the acquisition method of accounting (ASC 805-10-50), which requires that assets acquired and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. Transaction costs and costs to restructure the acquired company are expensed as incurred. The operating results of the acquired business are reflected in our consolidated financial statements after the date of acquisition. New Accounting Standards In February 2018, the FASB issued Accounting Standards Update No 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02). The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption of the amendments in this update is permitted, including adoption in any interim period, for public business entities for reporting periods for which financial statements have not yet been issued and for all other entities for reporting periods for which financial statements have not yet been made available for issuance. The Company is in the process of evaluating this accounting standard update. In August 2017, the FASB issued Accounting Standards Update No 2017-12, Derivative and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12). The amendments in ASU 2017-12 provide 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. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted in any interim period after issuance of the update. The Company is in the process of evaluating this accounting standard update. In May 2017, the FASB issued Accounting Standards Update No 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"). The amendments in ASU 2017-09 provide 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. The amendments in ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of this guidance is not expected to have a material impact on the Company's financial statements. In March 2017, the FASB issued Accounting Standards Update No 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 will change how employers that sponsor defined benefit pension and/or other post-retirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. Employers will present the other components of the net periodic benefit cost separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. These components will not be eligible for capitalization in assets. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods therein. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The guidance provides a practical expedient for disaggregating the service cost component and other components for comparative periods. The adoption of this guidance in 2018 is not expected to have a material impact on net income, and financial position. No changes to cash flows are expected from adoption. In January 2017, the FASB issued Accounting Standards Update No 2017-04, Intangibles—Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under Accounting Standards Codification (ASC) 350. The FASB issued new guidance that eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of today’s goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). The standard has tiered effective dates, starting in 2020 for calendar-year public business entities that meet the definition of an SEC filer. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is in the process of evaluating this accounting standard update. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"). ASU 2016-16 eliminates the exception to the principle in ASC 740, for all intra-entity sales of assets other than inventory, to be deferred, until the transferred asset is sold to a third party or otherwise recovered through use. This standard is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update No 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 clarifies how entities should classify certain cash receipts and cash payments in the statement of cash flows and amends certain disclosure requirements of ASC 230. The guidance will generally be applied retrospectively and is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those years. For all other entities, it is effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The adoption of this guidance is not expected to have a material impact on the Company's financial statements. In February of 2016, the FASB issued Accounting Standards Update No 2016-02 Leases ("ASU 2016-02"). ASU 2016-02 includes final guidance that requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to today’s accounting. The guidance also eliminates today’s real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. All entities will classify leases to determine how to recognize lease-related revenue and expense. Classification will continue to affect amounts that lessors record on the balance sheet. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. They have the option to use certain relief. Full retrospective application is prohibited. ASU 2016-02 is effective for public companies with annual periods beginning after December 15, 2018, and interim periods within those years. For all other entities, it is effective for annual periods beginning after December 15, 2019, and interim periods the following year. Early adoption is permitted for all entities. The Company has commenced a comprehensive project plan to direct the implementation of the new leases standard and an assessment of the impact to business processes. In May of 2014, the FASB issued Accounting Standard Update No. 2014-09 Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that the Company identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when it satisfies the performance obligations. The Company will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is required to be adopted in January of 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. The Company intends to adopt the new standard using the modified retrospective transition method effective January 1, 2018 and the adoption of this guidance is not expected to have a material impact on the Company's financial statements.

The Company used the net proceeds from the offering to repay all amounts outstanding under its then existing $230.0 million term loan credit facility, to redeem all of its $240.0 million aggregate principal amount 8.875% Senior Notes due 2018 at a redemption price equal to 102.219% of the principal amount thereof, together with accrued and unpaid interest, to the date of redemption, to pay fees and expenses relating to these transactions, and for working capital and other general corporate purposes. ABL Revolving Credit Facility On November 3, 2015, the Company refinanced its prior revolving credit facility by entering into a new Revolving Credit and Guaranty Agreement (the “ABL Facility”) with one of its existing lenders. The amount of the ABL Facility provides an aggregate facility limit of $55.0 million , subject to a borrowing base collateralized by eligible accounts receivable, inventory and equipment of Xerium Technologies, Inc., as a US borrower, Xerium Canada Inc., as Canadian borrower, and Huyck.Wagner Germany GmbH, Robec Walzen GmbH, and Stowe Woodward AG, as the European borrowers. The ABL Facility matures in November of 2020 and accrues interest at either an Alternative Base rate (Prime plus 75 bps) or Fixed LIBOR (LIBOR +175 bps). As of December 31, 2017 these rates were 5.25% and 3.37% , respectively. As of December 31, 2017 , an aggregate of $34.1 million is available for additional borrowings under the $55.0 million Revolving Credit and Guaranty Agreement ("ABL Facility"). This availability represents $36.9 million under the ABL revolver that is currently collateralized by certain assets of the Company, less $2.8 million of that facility committed for letters of credit or current borrowings. In addition, the Company had approximately $5.8 million available for borrowings under other small lines of credit.

Derivatives and Hedging

Derivatives and Hedging	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. From time to time, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known cash amounts, the value of which are determined by interest rates or foreign exchange rates. Cash Flow Hedges of Interest Rate Risk The Company’s objectives when using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company may use interest rate caps and interest rate swaps as part of its interest rate risk management strategy. Interest rate caps designated as cash flow hedges protect the Company from increases in interest rates above the strike rate of the interest rate cap. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company settled all hedges of interest rate risk contracts in 2016. Non-Designated Hedges of Foreign Exchange Risk Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to foreign exchange rates, but do not meet the strict hedge accounting requirements of Topic 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly to earnings. The Company, from time to time, may enter into foreign exchange forward contracts to fix currencies at specified rates based on expected future cash flows to protect against the fluctuations in cash flows resulting from sales denominated in foreign currencies. Additionally, to manage its cash exposure to fluctuations in foreign currency on intercompany balances and certain purchase commitments, the Company, from time to time, may use foreign exchange forward contracts. As of December 31, 2017 and 2016 , the Company had outstanding derivatives that were not designated as hedges in qualifying hedging relationships. The value of these contracts is recognized at fair value based on market exchange forward rates and is recorded in other assets or other liabilities on the Consolidated Balance Sheets. The following represents the fair value of these derivatives at December 31, 2017 and 2016 and the change in fair value included in foreign exchange loss in the years ended December 31, 2017 and 2016 : December 31, 2017 December 31, 2016 Fair value of derivative liability $ (591 ) $ (1,461 ) Twelve Months Ended December 31, 2017 Twelve Months Ended December 31, 2016 Change in fair value of derivative included in foreign exchange loss $ (1,357 ) $ (2,761 ) The following represents the notional amounts sold and purchased for the year ended December 31, 2017 : Foreign Currency Derivative Notional Sold Notional Purchased Non-designated hedges of foreign exchange risk $ 20,164 $ (25,590 ) Fair Value of Derivatives Under ASC Topic 820 ASC Topic 820, Fair Value Measurements and Disclosures (“Topic 820”), emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, Topic 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs including fair value of investments that do not have the ability to redeem at net asset value as of the measurement date or during the first quarter following the measurement date. The derivative assets or liabilities are typically based on an entity’s own assumptions, as there is little, if any, market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and the Company considers factors specific to the asset or liability. To comply with Topic 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counter-party’s nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilized Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counter-parties. However, as of December 31, 2017 and 2016 , respectively, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy. The Company does not have any derivatives valued using significant unobservable inputs (Level 3) as of December 31, 2017 or 2016 . The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 and 2016 , aggregated by the level in the fair value hierarchy within which those measurements fall.

Income Taxes	Income Taxes The components of domestic and foreign (loss) income before the provision for income taxes are as follows: Year ended December 31, 2017 2016 2015 U.S. $ (15,427 ) $ (43,041 ) $ (38,240 ) Foreign 14,420 30,705 47,325 Total $ (1,007 ) $ (12,336 ) $ 9,085 The components of the income tax provision (benefit) are as follows: Year ended December 31, 2017 2016 2015 Current: U.S. $ 1,002 $ 929 $ 1,196 Foreign 4,121 8,134 15,054 Total current 5,123 9,063 16,250 Deferred: U.S. 1,640 (1,707 ) (195 ) Foreign 6,876 1,926 (2,590 ) Total deferred 8,516 219 (2,785 ) Total provision $ 13,639 $ 9,282 $ 13,465 For the years ended December 31, 2017 and 2016 , the provision for income taxes was $13.6 million and $9.3 million respectively. The Company's effective income tax rate is primarily impacted by income the Company earns in tax-paying jurisdictions relative to income it earns in non-tax-paying jurisdictions. The majority of income recognized for purposes of computing the Company's effective tax rate is earned in countries where the statutory income tax rates range from 15.0% to 35.0% . The Company generates losses in certain jurisdictions for which it receives no tax benefit as the deferred tax assets in these jurisdictions (including the net operating losses) are fully reserved by a valuation allowance. For this reason, the Company recognizes minimal income tax expense or benefit in these jurisdictions, of which the most material jurisdictions are the United States, Germany and Australia. Due to these reserves, the geographic mix of its pre-tax earnings has a direct correlation with how high or low its annual effective tax rate is relative to consolidated earnings. On December 22, 2017, significant tax legislation was signed into U.S. law under the Tax Cuts & Jobs Act (“the Tax Act”). Key features of the Tax Act include a reduction of the corporate income tax rate from 35% to 21% ; limitations on the deductibility of future interest expense; and the transition of the U.S. system for international taxation from a worldwide tax regime to a modified-territorial tax regime, including the imposition of a tax on unrepatriated earnings of foreign subsidiaries (the “transition tax”). In response, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) which allows issuers to recognize provisional estimates of the impact of the Tax Act in their financial statements, or in circumstances where estimates cannot be made, to not report any impact and to disclose and recognize at a later date. As of December 31, 2017, the Company has not completed its accounting related to the enactment of the Tax Act, as follows: 1. Remeasurement of U.S. deferred tax assets - The Company has recorded a provisional estimate of $31.8 million discrete deferred tax expense related to the remeasurement of the U.S. deferred tax assets as a result of the reduction in the corporate income tax rate. A corresponding tax benefit was recorded related to the reduction in valuation allowance. 2. Transition tax - The Company has recorded a provisional estimate related to accounting for the transition tax and its impact on tax accounting for unrepatriated foreign earnings and other foreign income inclusions. The provisional estimate results in $0 current or deferred tax impact primarily as a result of the historic tax loss carry-forwards and the corresponding valuation allowance against related deferred tax assets. In order to complete the accounting, the Company will continue to analyze foreign earnings calculations as well as to await clarification of certain provisions of the Tax Act. 3. Deferred tax accounting on outside basis differences of controlled foreign corporations - The Company has recorded a provisional estimate related to the deferred tax accounting for basis differences associated with foreign subsidiaries. Historically, the Company has accrued U.S. deferred taxes in connection with certain foreign earnings which were not considered to be permanently reinvested as these earnings were expected to be distributed to the U.S. However, the transition tax has resulted in immediate U.S. taxation of previously untaxed foreign earnings. As a result, the Company has reversed the U.S. deferred taxes previously recognized on those foreign earnings that were not considered to be permanently reinvested. Additionally, future repatriation of foreign earnings (even those previously considered to be permanently reinvested) would not be expected to give rise to U.S. tax under the Tax Act’s territorial regime. Therefore, a provisional estimate has been recorded for deferred taxes on unrepatriated foreign earnings assuming none of the earnings are permanently reinvested. No additional U.S. income taxes have been provided in connection with any remaining untaxed foreign earnings or any additional outside basis difference with respect to investments in foreign subsidiaries as the Company assesses whether any investments should be considered as indefinitely reinvested in foreign operations. 4. Global Intangible Low-Taxed Income (“GILTI”) - The deferred tax accounting is incomplete for basis differences associated with foreign subsidiaries as it relates to GILTI, a new provision under the Tax Act. No provisional estimate has been provided. Relevant to the current financial statements, the election of an accounting policy with respect to deferred tax accounting for GILTI will depend, in part, on analyzing foreign income to estimate future GILTI inclusions, as well as clarification of certain provisions of the Tax Act. Until such analyses and clarifications are made, the Company has not made a policy decision regarding tax accounting for the GILTI provision. 5. State and Local Income Taxes - The Company has recorded a provisional estimate related to the tax accounting for state and local income taxes upon enactment of the Tax Act. The Company continues to gather and analyze information available related to the impact of the Tax Act on state and local taxes and awaits clarification from the municipalities in order to complete the accounting. To the extent a provisional estimate was made, the Company utilized previously issued guidance for the Tax Act in order to reach an estimate. However, these estimates are not capable of finalization given the lack of statutory and regulatory guidance in many areas, as well as the complexity in acquiring the data required to calculate the impact on the tax accounts. The Company will revise and conclude the accounting as and when additional information is obtained, which in many cases is contingent on the timing of issuance of guidance. For these reasons, the ultimate impact may differ from these provisional amounts due to, among other things, additional information, changes in interpretations and assumptions management has made, and changes based on additional statutory and regulatory guidance that may be issued. Acknowledging this uncertainty, accounting for the impacts of the Tax Act will be completed within the next twelve months. The provision for income taxes differs from the amount computed by applying the U.S. statutory tax rate of 35% to income before income taxes, due to the following: Year ended December 31, 2017 2016 2015 Book income at U.S. 35% statutory rate $ (352 ) $ (4,318 ) $ 3,180 State income and other taxes due, net of federal benefit 1,362 1,168 1,556 Foreign tax rate differential (2,716 ) (2,305 ) (1,927 ) Dividends and other foreign (loss) income (18,756 ) 11,233 11,079 Change in valuation allowance (944 ) 4,922 (544 ) Tax rate changes 32,730 290 (103 ) Tax credits and refunds (613 ) (91 ) (372 ) Change in unrecognized tax benefits 1,627 2,097 (372 ) Provision to return adjustments (74 ) (1,001 ) (68 ) Non-deductible expenses 1,350 2,246 1,246 Other, net (1,395 ) (2,913 ) (455 ) Other foreign permanent items 1,420 (2,046 ) (314 ) Settlement of tax assessments — — 559 Total $ 13,639 $ 9,282 $ 13,465 The effective tax rate on continuing operations for the year ended December 31, 2017 varied from the statutory rate of 35% primarily due to the tax effect of intra-period tax allocations, tax rate changes, dividends and other foreign income, and changes in valuation allowances. Included in the effective tax rate is a benefit of $0.5 million from the impact on intra-period tax allocations, included in the Other, net line in the table above. Intra-period tax allocation rules require that all items, including other comprehensive income and discontinued operations, be considered for purposes of determining the amount of tax benefit that results from a loss in continuing operations. As a result, an income tax benefit was recorded in continuing operations for the year ended December 31, 2017 , with offsets of income tax expense in other comprehensive income. The amount for tax rate changes of $32.7 million is primarily related to the remeasurement of U.S. deferred taxes under the Tax Act. The amount for dividends and other foreign income of $(18.8) million was primarily related to a change in deferred taxes on foreign unremitted earnings resulting from the Tax Act. The change in the valuation allowance primarily relates to a decrease in the U.S. valuation allowance partially offset by establishing a valuation allowance against certain German deferred tax assets. The effective tax rate on continuing operations for the year ended December 31, 2016 varied from the statutory rate of 35% primarily due to the tax effect of intra-period tax allocations, dividends and other foreign income, foreign rate differentials and changes in valuation allowances. Included in the effective tax rate is a benefit of $(2.2) million from the impact on intra-period tax allocations, included in the Other, net line in the table above. Intra-period tax allocation rules require that all items, including other comprehensive income and discontinued operations, be considered for purposes of determining the amount of tax benefit that results from a loss in continuing operations. As a result, an income tax benefit was recorded in continuing operations for the year ended December 31, 2016, with offsets of income tax expense in other comprehensive income. The amount for dividends and other foreign income of $11.2 million was primarily related to residual U.S. taxes provided on foreign earnings no longer considered permanently reinvested. The foreign rate differential arises as a result of income earned in countries where the statutory income tax rates vary from the U.S. statutory rate of 35% , for which Austria creates the Company’s largest tax rate benefit. The change in the valuation allowance is $4.6 million from US and $0.3 million from an increase of pre-tax losses generated in other foreign jurisdictions for which the Company has determined no benefit should be recorded. The effective tax rate on continuing operations for the year ended December 31, 2015 varied from the statutory rate of 35% primarily due to the tax effect of dividends and other foreign income, foreign rate differentials and changes in valuation allowances. The amount for dividends and other foreign income of $11.1 million was primarily related to residual U.S. taxes provided on foreign earnings no longer considered permanently reinvested. The foreign rate differential arises as a result of income earned in countries where the statutory income tax rates vary from the U.S. statutory rate of 35% , for which Austria creates the Company’s largest tax rate benefit. The change in the valuation allowance of $(0.5) million relates primarily to a decrease in domestic deferred tax assets of $(0.4) million , a removal of a portion of the Australian valuation allowance of $(1.1) million and an increase of pre-tax losses generated in other foreign jurisdictions for which the Company has determined no benefit should be recorded. For the years ended December 31, 2017 and 2016 , tax expense included a benefit of approximately $54 and $32 for a Chinese tax holiday that expired in the year ending December 31, 2017 . The Company utilizes the asset and liability method for accounting for income taxes in accordance with ASC Topic 740 , Income Taxes (“Topic 740”). Under Topic 740, deferred tax assets and liabilities are determined based on the difference between their financial reporting and tax basis. The assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company reduces its deferred tax assets by a valuation allowance if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. In making this determination, the Company evaluates all available information including the Company’s financial position and results of operations for the current and preceding years, as well as any available projected information for future years. The tax effect of temporary differences which give rise to deferred income tax assets and liabilities are as follows: Year Ended December 31, 2017 2016 Deferred tax assets arising from: Loss carryforwards $ 94,881 $ 117,485 Intangible assets, net 204 161 Pension and other benefit accruals 10,678 14,604 Tax credits 1,838 1,488 Investments 2,506 2,082 Interest and finance fees 1,261 972 Other allowances and accruals, net 10,948 10,676 Total 122,316 147,468 Deferred tax liabilities arising from: Property and equipment, net 18,689 21,096 Intangible assets, net 2,377 2,074 Foreign income inclusions 1,590 21,243 Other allowances and accruals, net 250 1,616 Total 22,906 46,029 Valuation allowance 102,204 97,859 Net deferred tax (asset) liability $ 2,794 $ (3,580 ) Deferred taxes are recorded as follows in the consolidated balance sheets: December 31, 2017 2016 Non-current deferred tax asset, net $ 10,103 $ 10,737 Non-current deferred tax liability, net 12,897 7,157 Net deferred tax (asset) liability $ 2,794 $ (3,580 ) As of December 31, 2017 , the Company has pre-tax net operating loss carry-forwards for U.S. federal income tax purposes of approximately $234.9 million that expire on various dates from 2025 through 2037 and federal tax credits of approximately $166 that either expire on various dates or can be carried forward indefinitely. As of December 31, 2017 , the Company has pre-tax net operating loss carry-forwards for U.S. state income tax purposes of approximately $257.7 million that expire on various dates from 2018 through 2037 . As of December 31, 2017 , the U.S. federal and U.S. state net operating loss carry-forwards and federal tax credits are fully reserved in our valuation allowance. The Company has foreign federal net operating loss carry-forwards of approximately $126.7 million and capital loss carry forwards of $7.7 million , the majority of which can be carried forward indefinitely, and federal and provincial tax credits of approximately $1.7 million that begin to expire primarily in 2024 or are carried forward indefinitely. As of December 31, 2017 , $103.8 million , $7.7 million and $0.2 million , of foreign federal net operating loss carry-forwards, capital loss carry-forwards and federal and provincial tax credits, respectively, are reserved in our valuation allowance. Historic and future ownership changes could potentially reduce the amount of net operating loss carry-forwards available for use. As of December 31, 2017 , the Company had a valuation allowance in place for certain of its deferred tax assets due to the Company’s accumulated loss position and its uncertainty around the future profitability in certain of its tax jurisdictions. The valuation allowance primarily relates to deferred tax assets for available net operating loss carry forwards in the United States, the U.K., Germany, Sweden, France, Australia, China, Turkey and Spain. While the Company believes it has adequately provided for its income tax assets and liabilities in accordance with Topic 740, it recognizes that adverse determinations by taxing authorities, or changes in tax laws and regulations could have a material adverse effect on its consolidated financial position, results of operations or cash flows. During the year ended December 31, 2017 , the Company reassessed its valuation allowance requirements related to its German operations, evaluating all available evidence in its analysis, both positive and negative, including historical and projected income and losses before the provision for income taxes, as well as reversals of temporary differences. The Company also considered tax planning strategies. During the year ended December 31, 2017 , the Company recorded $4.2 million of tax expense related to establishing a valuation allowance against certain of its German deferred tax assets. The Company believes that it is more likely than not for the deferred tax assets to remain unrealized based on estimates of future taxable income generated by future earnings of its German businesses. In light of the enactment of the Tax Act, the Company evaluated the recoverability of the U.S. deferred tax assets. It remains more likely than not that the deferred tax assets in connection with our U.S. operations will not be realized. Although projections of future U.S. taxable income indicate realization of the primary U.S. deferred tax asset (the tax loss carry-forwards) as a result of limitations on the deductibility of future interest expense, such limitations will have a corresponding increase to deferred tax assets. As the Company continues to reorganize and restructure its operations, it is possible that deferred tax assets, for which no income tax benefit has previously been provided, may more likely than not become realized. The Company continues to evaluate future operations and will record an income tax benefit in the period where it believes it is more likely than not that the deferred tax asset will be able to be realized. Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $138.5 million at December 31, 2017 . Prior to enactment of the Tax Act, earnings generated prior to 2013 were considered to be indefinitely reinvested for continued use in foreign operations except for a portion of the earnings generated by our Brazil and China operations. All earnings generated in all foreign subsidiaries after 2012 were not considered to be permanently reinvested, because of the Company's desire to manage global cash and liquidity related to ongoing financial obligations, capital expenditures, restructuring payments and other changes in business conditions going forward. However, the transition tax has resulted in immediate U.S. taxation of our previously untaxed foreign earnings. As a result, the Company has reversed the U.S. deferred taxes previously recognized on those foreign earnings that were not considered to be permanently reinvested. Additionally, future repatriation of foreign earnings (even those previously considered to be permanently reinvested) would not be expected to give rise to U.S. tax under the Tax Act’s territorial regime. Therefore, the Company has recorded a provisional estimate for deferred taxes on unrepatriated foreign earnings assuming none of the earnings are permanently reinvested. Foreign withholding taxes are provided on the portion of the income of foreign subsidiaries that is expected to be remitted to the United States and be taxable. The Company accrues for certain known and reasonably anticipated income tax obligations after assessing the likely outcome. In the event that actual results differ from these accruals or if the Company becomes subject to a tax obligation for which the Company has made no accrual, the Company may need to make adjustments, which could materially impact the financial condition and results of operations. For example, taxing authorities may disagree with the Company’s tax accounting methodologies and may subject the Company to inquiries regarding such taxes, which potentially could result in additional income tax assessments. In accordance with ASC 740-10-25-6, the Company does not accrue for potential income tax obligations if management deems a particular tax position, based solely on its technical merits, is more likely than not to be sustained upon examination. In making this determination, the Company assumes that the taxing authorities will have access to all relevant facts and information in accordance with ASC 740-10-25-7. As of December 31, 2017 , the Company had a gross unrecognized tax benefit of $10.0 million , exclusive of interest and penalties. The unrecognized tax benefit increased by approximately $0.7 million and $1.8 million during the years ended December 31, 2017 and 2016 , respectively. The unrecognized tax benefit increased primarily as a result of current year positions related to transfer pricing policies and currency effects. A reconciliation of the balances of the unrecognized tax benefits is as follows, excluding interest and penalties: Year Ended December 31, 2017 2016 2015 Balance as of January 1 $ 9,285 $ 7,527 $ 7,502 Gross increases (decreases)-tax positions in prior period-other (1,942 ) 849 (104 ) Gross decreases-related to lapse in statute of limitations (172 ) (115 ) (209 ) Gross increases-tax positions in current period 2,342 1,046 688 Currency effects 499 (22 ) (350 ) Balance at December 31 $ 10,012 $ 9,285 $ 7,527 The Company’s policy is to recognize interest and penalties related to income tax matters as income tax expense, and accordingly, the Company recorded a $0.2 million expense, including currency effects, and a $0.9 million expense, including currency effects, for interest and penalties during the years ended December 31, 2017 and 2016 , respectively. As of December 31, 2017 and 2016 , the Company had accrued interest and penalties related to uncertain tax positions of approximately $2.3 million and $1.7 million , respectively. If the Company were to prevail on all unrecognized tax benefits recorded, approximately $7.9 million would benefit the effective tax rate. During the next twelve months, management estimates a range between $0 and $10 of the Company's gross unrecognized tax benefit will reverse due to expected settlements and statute of limitations expiring which relate to various items and will benefit the effective tax rate. The Company regularly evaluates, assesses and adjusts the related liabilities in light of changing facts and circumstances, which could cause the effective tax rate to fluctuate from period to period. The tax years 2005 through 2017 remain open to examination in the Company's U.S. Federal jurisdiction, and the tax years 2001 through 2017 remain open to examination in the Company's U.S. state jurisdictions. The tax years 2003 through 2017 remain open to examination in the major foreign tax jurisdictions to which the Company and its subsidiaries are subject. There are currently no U.S. Federal audits or examinations underway. The Company has ongoing audits or tax litigation in Italy. During 2017 , tax audits related to the German Rolls business were closed, with no significant changes. The Company believes that it has made adequate provisions for all income tax uncertainties.

Retirement Benefits [Abstract]
Pensions and Other Post Retirement Benefits	Pensions and Other Post Retirement Benefits Pension Plans The Company accounts for its pensions, other post-retirement and post-employment benefit plans in accordance with ASC Topic 715, Compensation—Retirement Benefits (“Topic 715”). The Company has defined benefit pension plans covering substantially all of its U.S. and Canadian employees and employees of certain subsidiaries in other countries. Benefits are generally based on the employee’s years of service and compensation. These plans are funded in conformity with the funding requirements of applicable government regulations. The Company does not fund certain plans, as funding is not required. Approximately $47.1 million of the total underfunded status of $67.1 million and $43.1 million of the total underfunded status of $64.8 million relate to these unfunded pension plans as of December 31, 2017 and 2016 , respectively. The Company plans to continue to fund its U.S. defined benefit plans to comply with the Pension Protection Act of 2006. In addition, the Company also intends to fund its U.K. and Canadian defined benefit plans in accordance with local regulations. Additional discretionary contributions are made when deemed appropriate to meet the long-term obligations of the plans. In accordance with the provisions of Topic 715, the measurement date for defined benefit plans is December 31. Benefit Obligations and Plan Assets A summary of the changes in benefit obligations and plan assets as of December 31, 2017 and 2016 is presented below. Defined Benefit Plans 2017 2016 Change in benefit obligation Benefit obligation at beginning of year $ 153,256 $ 149,108 Service cost 1,523 1,668 Interest cost 4,595 5,133 Plan participants’ contributions 15 22 Actuarial loss 7,243 15,583 Currency translation impact 10,148 (7,796 ) Administrative expenses paid (237 ) (191 ) Settlement/curtailment (6,531 ) (2,700 ) Benefits paid (7,652 ) (7,571 ) Benefit obligation at end of year 162,360 153,256 Change in plan assets Fair value of plan assets at beginning of year 88,468 86,313 Actual return on plan assets 9,387 9,789 Employer contributions 6,809 5,460 Plan participants’ contributions 15 22 Settlement (6,531 ) — Administrative expenses paid (237 ) (191 ) Currency translation impact 5,040 (5,354 ) Benefits paid (7,652 ) (7,571 ) Fair value of plan assets at end of year 95,299 88,468 Funded status $ (67,061 ) $ (64,788 ) Balance sheet classification of funded status Other assets - non-current $ 1,390 $ — Accrued expenses $ (3,124 ) $ (3,080 ) Pension, other post-retirement and post-employment obligations $ (65,327 ) $ (61,708 ) Funded status $ (67,061 ) $ (64,788 ) The total accumulated benefit obligation was $158.8 million and $150.0 million as of the years ended December 31, 2017 and 2016 , respectively. All of the Company’s pension plans that comprise the pension obligation amounts above, with the exception of Canada in 2017, have a projected benefit obligation equal to or in excess of plan assets. Information for pension plans with an accumulated benefit obligation in excess of plan assets is as follows: December 31, 2017 2016 Projected benefit obligation $ 141,452 $ 153,256 Accumulated benefit obligation $ 137,918 $ 150,005 Fair value of plan assets $ 73,001 $ 88,468 Components of Net Periodic Benefit Cost Defined Benefit Plan 2017 2016 2015 Service cost $ 1,523 $ 1,668 $ 3,256 Interest cost 4,595 5,133 5,656 Expected return on plan assets (5,412 ) (5,383 ) (6,221 ) Settlement losses 921 — 1,108 Amortization of net loss 2,133 1,949 2,139 Net periodic benefit cost $ 3,760 $ 3,367 $ 5,938 The total unrecognized net loss recorded in Other Comprehensive Loss at December 31, 2017 is $46.3 million , gross of tax. For defined benefit plans, the estimated net loss to be amortized from accumulated other comprehensive loss during 2018 is expected to be $2.3 million . Additional Information Defined Benefit Plans 2017 2016 Change in funded status included in accumulated other comprehensive loss, net of tax $ 2,664 $ 3,687 Assumptions Weighted-average assumptions used to determine benefit obligations at December 31 are as follows: Defined Benefit Plans 2017 2016 Discount rate 2.75 % 3.10 % Rate of compensation increase 3.48 % 3.47 % Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31 are as follows: Defined Benefit Plans 2017 2016 Discount rate 3.10 % 3.67 % Expected long-term return on plan assets 6.23 % 6.42 % Rate of compensation increase 3.47 % 3.50 % The expected long-term return on plan assets is calculated based on a building-block approach, whereby the components are weighted based on the long-term allocation of pension plan assets. Plan Assets The percentage of fair value of total plan assets for funded plans are invested as follows: Plan Assets at December 31, Asset Category 2017 2016 Marketable equities 56 % 56 % Fixed income securities 44 % 44 % Total 100 % 100 % The Company’s plan assets are invested in the U.S., the U.K. and Canada. Plan asset investments are accounted for at cost on the trade date and are reported at fair value, using the net asset value per share practical expedient. Canadian plan assets totaling $22.3 million , U.K. plan assets totaling $37.0 million and U.S. plan assets totaling $36.0 million are classified as Level 2 within the fair value hierarchy. Level 2 valuations are based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. In general, plan assets are exposed to various risks, such as interest rate risk, credit risk, and overall market volatility. Due to the level of risk associated with certain investments, it is reasonably possible that changes in the values of investments will occur in the near term and that such changes could materially affect the amounts reported in the plan assets. The investment objective of the plans is to maximize the return on plan assets over a long time horizon, while meeting the plan obligations. Investment risk is substantially reduced by diversification of investments within particular asset classes. The expected future rate of return on plan assets is based on historic performance of bonds and equities and the higher returns expected by equity-based capital relative to debt capital. The agreements with the fund managers include a number of restrictions which are designed to ensure that only suitable investments are held. Generally, investment performance is provided to and reviewed by the Company on a quarterly basis. If any changes take place in the legal, regulatory or tax environment which impact the investment of the portfolios or the investment returns, the fund manager is expected to notify the Company immediately and to advise on their anticipated impact. Details relating to the Company’s plan assets are as follows: U.S. Plan Assets : The Company’s U.S. plan assets are 51% invested in marketable equity securities and 49% invested in fixed income securities managed by the fund manager. This allocation is in accordance with the strategic allocation adopted by the Company’s pension committee comprising of approximately 50% equity investment and 50% bond investment. U.K. Plan Assets : The Company’s U.K. plan assets are 52% invested in marketable equity securities and 48% invested in fixed income securities managed by the fund manager. The trustees of the U.K. pension plan have adopted a strategic allocation comprising of 50% equity investment and 50% bond investment. Canadian Plan Assets : The Company’s Canadian plan assets are 71% invested in marketable equity securities and 29% invested in fixed income securities managed by the fund manager. The Company’s pension committee has adopted a strategic allocation comprising of approximately 65% equity investment and 35% bond investment. Contributions and Benefit Payments The Company expects to make contributions to its funded defined benefit plans and benefit payments to its unfunded defined benefit plans totaling approximately $6.8 million in 2018 . Estimated Future Benefit Payments The following benefit payments related to both the Company's funded and unfunded defined benefit plans, which reflect expected future service, as appropriate, are expected to be paid: Defined Benefit Plans 2018 $ 7,049 2019 6,846 2020 7,088 2021 8,058 2022 7,729 Years 2023 and thereafter 39,610 The Company sponsors various unfunded defined contribution plans that provide for retirement benefits to employees, some in accordance with local government requirements. The Company also maintains a funded retirement savings plan for U.S. employees which is qualified under Section 401(k) of the U.S. Internal Revenue Code. The plan allows eligible employees to contribute up to 99% of their compensation (subject to certain Internal Revenue Service limitations), with the Company matching up to 4% of employee compensation. The following represents the approximate matching contribution expense for the years ended December 31, 2017 , 2016 and 2015 : Year ended December 31, 2017 2016 2015 Matching contribution expense $ 1,834 $ 1,590 $ 1,333

Operating lease rental expense was $2.3 million , $2.4 million , and $3.2 million during the years ended December 31, 2017 , 2016 and 2015 , respectively. These leases expire at various dates through 2023 . At December 31, 2017 , future minimum rental payments due under non-cancelable operating leases were as follows: 2018 $ 1,748 2019 1,541 2020 1,144 2021 888 2022 554 Thereafter 38 Total minimum operating lease payments $ 5,913 Collective Bargaining and Union Agreements Approximately 69% of the Company’s employees either are subject to various collective bargaining agreements or are members of trade unions, employee associations or workers councils predominantly outside of the United States. Approximately 1.0% of those employees subject to collective bargaining agreements, or 0.7% of the Company’s total employees, are covered by agreements that are set to expire during 2018. Legal Proceedings The Company and its subsidiaries are involved in various legal matters, which have arisen in the ordinary course of business as a result of various labor claims, taxing authority reviews and other legal matters. As of December 31, 2017 , the Company had accrued an immaterial amount in its financial statements for these matters for which (1) management believed the possibility of loss was either probable or possible and (2) was able to estimate the damages. These estimates have been developed in consultation with counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future results of operations for any particular period could be materially affected by changes in the Company’s assumptions or the effectiveness of our strategies related to these proceedings. Environmental Matters The Company’s operations and facilities are subject to a number of national, state and local laws and regulations protecting the environment and human health in the United States and foreign countries that govern, among other things, the handling, storage and disposal of hazardous materials, discharges of pollutants into the air and water and workplace safety. Because of the Company’s operations, the history of industrial uses at some of these facilities, the operations of predecessor owners or operators of some of the businesses, and the use and release of hazardous substances at these sites, the liability provisions of environmental laws may affect the Company. The Company is not aware of any material unasserted claims. The Company believes that any additional liability in excess of amounts provided which may result from the resolution of such matters will not have a material adverse effect on the financial condition, liquidity or cash flow of the Company.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Long-term Incentive and Stock-Based Compensation	Long-term Incentive and Stock-Based Compensation The Company records stock-based compensation expense in accordance with ASC Topic 718, Accounting for Stock Compensation ("Topic 718") and has used the straight-line attribution method to recognize expense for time-based restricted stock units ("RSUs") and deferred stock units ("DSUs") and recognizes expense for the performance and market-based restricted stock units based on management's estimate of performance against the targets in each plan. The Company recorded stock-based compensation expense during the years ended December 31, 2017 , 2016 and 2015 as follows: For the Years Ended December 31, 2017 2016 2015 RSU and DSU Awards (1) $ 2,518 $ 2,240 $ 2,740 Other Awards (2) — 372 558 Total $ 2,518 $ 2,612 $ 3,298 (1) Related to RSUs, Options and DSUs awarded to certain employees and non-employee directors. The year ended December 31, 2017 includes approximately $1.2 million of expense related to the accelerated vesting on RSU's upon CEO transition. Upon transition 146,134 shares were issued to the former CEO. (2) This amount relates to options awarded on August 15, 2012 to the former CEO. Long-Term Incentive Program - 2017 LTIP On May 30, 2017, the Board of Directors approved the 2017 - 2019 Long-Term Incentive Plan (the "2017 LTIP") which provides for the grant of incentive award opportunities (each, an "Award") payable, if earned, in cash. Because any Award under the 2017 LTIP will be paid in cash, and not equity, the Awards granted under the 2017 LTIP are not made pursuant to the Xerium Technologies, Inc. 2010 Equity Incentive Plan (the "EIP"). As of December 31, 2017 , the total fair market value of these awards was $1.1 million of which $0.2 million was recorded in general and administrative expense in the Consolidated Statement of Operations for the year ended December 31, 2017 . Awards will consist of Phantom Stock Units. Each Phantom Stock Unit represents the right to receive a cash amount equal to the Average Value of one share of common stock of the Company as described below: • 125,535 Time-based awards, or 50% of the total target award for each participant, have been granted in the form of time-based units. The time-based units vest on the third anniversary of the date of grant. • 125,535 Performance-based awards, or 50% of the total target award for each participant, have been granted in the form of performance-based units. Of these units, one half will vest based on the financial performance of the Company as measured by Adjusted EBITDA, and one half will vest based on the Return on Net Assets (as defined in the 2017 LTIP) of the Company. Half of the performance-based units whose vesting is subject to the financial performance of the Company will vest based on the degree to which the Company achieves a targeted three -year cumulative Adjusted EBITDA metric, adjusted for currency fluctuations, over the performance period of January 1, 2017 through December 31, 2019. The amount of units that vest will range from 50% to 200% of the employee's total units. Half of the performance-based units whose vesting is subject to the financial performance of the Company will vest based on the degree to which the Company achieves an average three -year Return on Net Assets metric over the performance period of January 1, 2017 through December 31, 2019. The amount of units that vest will range from 50% to 200% of the employee's total units. Long-Term Incentive Program—2016 LTIP, 2015 LTIP and 2014 LTIP Long-Term Incentive Program—2016 LTIP On May 4, 2016, the Board of Directors approved the 2016 - 2018 Long-Term Incentive Plan (the “2016 - 2018 LTIP”) under the 2010 Equity Incentive Plan (the “2010 Plan”). Awards under the 2016 - 2018 LTIP are time-based, performance-based and market-based. A specific target share award has been set for each participant in the 2016 - 2018 LTIP. Awards will be paid in the form of shares of common stock of the Company, as described below: • 182,190 Time-based awards, or 35% of the total target award for each participant, have been granted in the form of time-based restricted stock units under the Company’s 2010 Plan. The time-based restricted stock units vest on the third anniversary of the date of grant. • 338,354 Performance-based and Market-based awards, 65% of the total target award for each participant, have been granted in the form of performance-based stock units under the 2010 Plan. Of these units, one third will vest based on the financial performance of the Company as measured by Adjusted EBITDA, one third will vest based on the free cash flow of the Company and the other one third will vest based on the stock price performance of the Company. • On August 2, 2016 an additional amount of 8,562 time-based awards and 15,900 performance based awards were granted under the 2016-2018 LTIP. Half of the performance-based stock units whose vesting is subject to the financial performance of the Company (the “financial stock units”) will vest based on the degree to which the Company achieves a targeted three -year cumulative Adjusted EBITDA metric, adjusted for currency fluctuations, over the performance period of January 1, 2016 through December 31, 2018. Financial stock units that vest will convert into shares of the Company’s common stock and be paid after the close of a three -year performance period. The amount of units that vest will range from 50% to 200% of the employee's total financial stock units. Upon attainment of cumulative Adjusted EBITDA equal to 90% or less of the targeted Adjusted EBITDA, none of the financial stock units will vest. Upon attainment of more than 90% of the targeted Adjusted EBITDA, the financial stock units will begin vesting on a straight-line basis from 50% of the financial stock units at 90% of the targeted Adjusted EBITDA to 100% of the financial stock units at 100% of the targeted Adjusted EBITDA, up to a maximum payout of 200% of the financial stock units at 110% of the targeted Adjusted EBITDA. Half of the performance-based stock units whose vesting is subject to the financial performance of the Company (the “financial stock units”) will vest based on the degree to which the Company achieves a targeted three -year cumulative Free Cash Flow metric, adjusted for currency fluctuations, over the performance period of January 1, 2016 through December 31, 2018. Financial stock units that vest will convert into shares of the Company’s common stock and be paid after the close of a three -year performance period. The amount of units that vest will range from 50% to 200% of the employee's total financial stock units. Upon attainment of cumulative Free Cash Flow equal to 88% or less of the targeted Free Cash Flow, none of the financial stock units will vest. Upon attainment of more than 88% of the targeted Free Cash Flow, the financial stock units will begin vesting on a straight-line basis from 50% of the financial stock units at 88% of the targeted Free Cash Flow to 100% of the financial stock units at 100% of the targeted Free Cash Flow, up to a maximum payout of 200% of the financial stock units at 113% of the targeted Free Cash Flow. The market-based stock units whose vesting is subject to stock price performance of the Company (the “market-based stock units”) will vest based on the Company's total stock price change (plus dividends) over the three -year performance period of May 4, 2016 through May 4, 2019 (“TSR”) relative to the TSR over the same performance period of companies listed on the S&P Global Small Cap Index on the third anniversary of the grant date, or May 4, 2019. Market-based stock units that vest will convert into shares of the Company’s common stock and will be paid after the third anniversary of the grant date, or May 4, 2019. The amount of units that vest will range from 50% to 200% of the employee's total market-based stock units. If the Company’s TSR over the performance period is less than the 35th percentile TSR of companies in the S&P Global Small Cap Index, then no market-based units will vest. If the Company’s TSR over the performance period is equal to the 35th percentile TSR of the companies in the S&P Global Small Cap Index, then 50% of the market-based stock units will vest. Full payout at 100% of the market-based stock units will be made if the Company’s TSR over the performance period is equal to the 55th percentile TSR of companies in the S&P Global Small Cap Index and payout of 200% of the market-based stock units made if the Company's TSR over the performance period is equal to the 75th percentile TSR of companies in the S&P Global Small Cap Index. TSR performance between the 35th and 75th percentile TSR of companies in the S&P Global Small Cap Index will result in an interpolated payout percentage of the market-based stock units between 50% and 200% . Subject to early acceleration and payment under certain circumstances consistent with the terms of the Company’s 2016 - 2018 LTIP and LTIP Share Agreement thereunder, delivery of shares of common stock underlying the time-based, performance-based and market-based awards that become vested are subject to the participant’s continued service to the Company through May 4, 2019. Long-Term Incentive Program—2015 LTIP On March 2, 2015, the Board of Directors approved the 2015-2017 Long-Term Incentive Plan (the “2015 - 2017 LTIP”) under the 2010 Equity Incentive Plan (the “2010 Plan”). Awards under the 2015 - 2017 LTIP are time-based, performance-based and market-based. A specific target share award has been set for each participant in the 2015-2017 LTIP. Awards will be paid in the form of shares of common stock of the Company, as described below: • 52,601 time-based awards, or 35% of the total target award for each participant, have been granted in the form of time-based restricted stock units under the Company’s 2010 Plan. The time-based restricted stock units vest on the third anniversary of the date of grant. • 97,681 performance-based and market-based awards, 65% of the total target award for each participant, have been granted in the form of performance-based stock units under the 2010 Plan. Of these units, half will vest based on the financial performance of the Company and the other half will vest based on the stock price performance of the Company. The performance-based stock units whose vesting is subject to the financial performance of the Company (the “financial stock units”) will vest based on the degree to which the Company achieves a targeted three -year cumulative Adjusted EBITDA metric, adjusted for currency fluctuations, over the performance period of January 1, 2015 through December 31, 2017. Financial stock units that vest will convert into shares of the Company’s common stock and be paid after the close of a three -year performance period. The amount of units that vest will range from 0% to 100% of the employee's total financial stock units. Upon attainment of cumulative Adjusted EBITDA equal to 80% or less of the targeted Adjusted EBITDA, none of the financial stock units will vest. Upon attainment of more than 80% of the targeted Adjusted EBITDA, the financial stock units will begin vesting on a straight-line basis from 0% of the financial stock units at 80% of the targeted Adjusted EBITDA to 100% of the financial stock units at 100% of the targeted Adjusted EBITDA, up to a maximum payout of 100% of the financial stock units. The market-based stock units whose vesting is subject to stock price performance of the Company (the “market-based stock units”) will vest based on the Company's total stock price change (plus dividends) over the three -year performance period of March 2, 2015 through March 2, 2018 (“TSR”) relative to the TSR over the same performance period of companies listed on the S&P Global Small Cap Index on the third anniversary of the grant date, or March 2, 2018.

The amount of units that vest will range from 0% to 100% of the employee's total market-based stock units. If the Company’s TSR over the performance period is less than the 35th percentile TSR of companies in the S&P Global Small Cap Index, then no market-based units will vest. If the Company’s TSR over the performance period is equal to the 35th percentile TSR of the companies in the S&P Global Small Cap Index, then 50% of the market-based stock units will vest. Full payout at 100% of the market-based stock units will be made if the Company’s TSR over the performance period is equal to the 55th percentile TSR of companies in the S&P Global Small Cap Index. TSR performance between the 35th and 55th percentile TSR of companies in the S&P Global Small Cap Index will result in an interpolated payout percentage of the market-based stock units between 50% and 100% . Long-Term Incentive Program—2014 LTIP Awards under the 2014 LTIP vested on May 8, 2017, and were converted to 13,829 shares of common stock, net of withholdings.

A summary of RSUs outstanding as of December 31, 2017 and their vesting dates is as follows. Plan Description Remaining Vesting Dates Number of RSUs DSU's Vested immediately upon grant, on a quarterly basis 92,418 Executive time-based RSUs granted during 2015 March 2, 2018 17,534 Executive market and performance based RSUs granted during 2015 March 2, 2018 32,560 Executive time-based RSUs granted during 2016 May 5, 2019 and August 2, 2019 76,026 Executive market and performance based RSUs granted during 2016 May 5, 2019 and August 2, 2019 141,192 CEO RSU Award October 28, 2020 600,000 959,730 RSU activity during years ended December 31, 2017 , 2016 and 2015 , are presented below. Number of RSUs Price Range of Grant- Date Fair Value Per RSU Weighted Average Grant-Date Fair Value Price Per RSU Outstanding, December 31, 2014 738,724 $4.04 – $21.69 $ 8.61 Granted 181,831 $9.71 – $15.97 $ 14.93 Forfeited (282 ) $8.25 $ 8.25 Issued or withheld for tax withholding purposes (104,917 ) $4.04 – $9.71 $ 5.35 Outstanding, December 31, 2015 815,356 $4.04 – $21.69 $ 10.93 Granted 619,669 $5.02 – $7.95 $ 5.24 Forfeited (40,468 ) $5.02 – $15.97 $ 7.94 Issued or withheld for tax withholding purposes (520,820 ) $2.90 – $15.97 $ 8.62 Outstanding, December 31, 2016 873,737 $2.90 – $24.05 $ 8.40 Granted 698,809 $4.26 – $7.19 $ 6.76 Forfeited (253,846 ) $5.02 – $15.97 $ 6.78 Issued or withheld for tax withholding purposes (358,970 ) $4.26 – $15.97 $ 9.56 Outstanding, December 31, 2017 959,730 $2.90 – $24.05 $ 7.20 Exercisable, December 31, 2017 (1) 92,418 $2.90 – $24.05 $ 8.34 (1) The Company had 92,418 non-employee director DSUs that have vested, but have not yet been converted to common stock. These DSUs have a weighted average grant-date fair value price per share of $8.34 and a total grant-date fair value of $0.8 million . As the non-employee director can elect to defer the receipt of these DSUs until six months following their retirement from the Board of Directors, there is no definite weighted average life of these DSUs. Assumptions In accordance with Topic 718, the Company uses the following assumptions in determining compensation expense: Grant-Date Fair Value The Company calculates the grant-date fair value of time-based RSUs, performance-based RSUs and non-employee directors’ DSUs based on the closing price of the Company’s common stock on the date of grant. Forfeitures As the time-based and performance-based RSUs require continued employment or service up to the time of vesting, the amount of stock-based compensation recognized during a period can include an estimate of forfeitures. Under ASU 2016-09 Improvements to Employee Share-Based Payment Accounting , entities will have to elect whether to account for forfeitures of share-based payments by (1) recognizing forfeitures of awards as they occur (e.g., when an award does not vest because the employee leaves the company) or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is no longer probable that the employee will fulfill the service condition, as is currently required. For awards with performance conditions, an entity will continue to follow ASC 718 and assess the probability that a performance condition will be achieved at each reporting period to determine whether and when to recognize compensation cost, regardless of its policy election for forfeitures. No estimate of forfeitures has been made for RSUs and DSU’s awarded to non-employee directors because they vest immediately upon grant. Forfeitures are to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is related to employee attrition and based on a historical analysis of its employee turnover. This analysis is re-evaluated quarterly and the forfeiture rate will be adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will be only for those shares that meet the requirements of continued employment up to the time of vesting. As of December 31, 2017 , the forfeiture rates for the 2015 , 2016 and 2017 plans are estimated at 0% . As of December 31, 2017 , there was approximately $1.0 million of total unrecognized compensation expense related to un-vested share-based awards which is expected to be recognized over a weighted average period of 2.10 years . Dividends The Company’s Indenture to the Notes and ABL Facility generally prohibit the payment of dividends. No such payments were made during the years ended December 31, 2017 and 2016 .

Restructuring and Related Activities [Abstract]
Restructuring Expense	Restructuring Expense Restructuring expense included in the Company’s statements of operations are the result of its long-term strategy to reduce production costs and improve long-term competitiveness. Restructuring and impairments expense consists principally of severance costs related to reductions in work force and of facility costs and impairments of assets principally related to closing facilities and/or the relocation of production to another facility. Impairment amounts for assets held for sale reflect estimated selling prices less costs to sell and are considered to be a Level 2 within the fair value hierarchy. Facility costs are principally comprised of costs to relocate assets to the Company’s other facilities and other associated costs. During 2017, the Company incurred restructuring expenses of $ 7.9 million relating to headcount reductions and other costs related to previous plant closures partially offset by the reversal of a reserve for a potential exposure that was deemed no longer necessary. During 2016, the Company incurred restructuring expenses of $10.4 million . These included $1.8 million of charges related to the closure of the Middletown, VA facility and $8.6 million of charges related to headcount reductions and other costs relating to previously announced plant closures. During 2015, we incurred restructuring expenses of $14.6 million . These included $4.4 million of charges related to the closure of the Joao Pessoa, Brazil clothing facility; $4.9 million of charges related to the closure of the Warwick, Canada machine clothing facility; and $6.4 million of charges relating to headcount reductions, and other costs relating to previously announced plant closures. The costs were partially offset by a gain of $1.1 million on the sale of the Joao Pessoa, Brazil machine clothing facility in the fourth quarter of 2015. The Company expects to continue to review its business to determine if additional actions will be taken to further improve its cost structure. Restructuring expenses of approximately $1.0 million to $3.0 million are estimated during 2018 , primarily related to the continuation of streamlining the operating structure and improving long-term competitiveness of the Company. Actual restructuring costs for 2018 may substantially differ from estimates at this time, depending on actual operating results in 2018 and the timing of the restructuring activities. The table below sets forth the significant components and activity in the restructuring program during the years ended December 31, 2017 , 2016 and 2015 : 2017 Balance at Charges (1) Currency Cash Balance at Severance $ 3,805 $ 3,549 $ 685 $ (5,353 ) $ 2,686 Facility costs and other 392 3,359 71 (3,089 ) 733 Total $ 4,197 $ 6,908 $ 756 $ (8,442 ) $ 3,419 (1) Not included in the charges for 2017 in the table above is $ 0.9 million related to a pension settlement charge.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information The Company is a global manufacturer and supplier of consumable products used primarily in the production of paper and is organized into two reportable segments: clothing and roll covers. The clothing segment represents the manufacture and sale of synthetic textile belts used to transport paper or other materials along the length of papermaking or other industrial machines. The roll covers segment primarily represents the manufacture and refurbishment of covers used on the steel rolls of papermaking or manufacturing machines and the servicing of those rolls. The Company manages each of these operating segments separately. Management evaluates segment performance based on adjusted earnings before interest, taxes, depreciation and amortization, yet after allocation of corporate charges. Such measure is then adjusted to exclude items that are of an unusual nature and are not used in measuring segment performance or are not segment specific (“Segment Earnings (Loss)”). The accounting policies of these segments are the same as those for the Company as a whole as described in Note 2. Inter-segment net sales and inter-segment eliminations are not material for any of the periods presented. The corporate column consists of the Company’s headquarters, related assets and expenses that are not allocable to reportable segments. Significant corporate assets include cash, investments in subsidiaries and deferred financing costs. Corporate depreciation and amortization consists primarily of deferred financing costs.

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements have been prepared on the basis of U.S. generally accepted accounting principles ("U.S. GAAP"). The consolidated financial statements include the accounts of Xerium Technologies, Inc. and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated.
Revenue Recognition	Revenue Recognition Revenue on product sales is recognized when persuasive evidence of an arrangement exists, the price is fixed and determinable, delivery including transfer of title has occurred and there is a reasonable assurance of collection of the sales proceeds. The Company generally obtains written purchase authorizations from customers for a specific product or service at a specified price and considers delivery and transfer of title to have occurred in accordance with our shipping terms. Revenue is recorded net of applicable allowances, including estimated allowances for returns, rebates and other discounts. In the machine clothing segment, a small portion of the business has been conducted pursuant to consignment arrangements under which the Company does not recognize a sale of a product to a customer until the customer places the product into use, which typically occurs some period after the product is shipped to the customer or to a warehouse location near the customer’s facility. As part of the consignment agreement, the Company delivers the goods to a location designated by the customer. In addition, the customer and the Company agree to a “sunset” date, which represents the date by which the customer must accept all risks and rewards of ownership of the product and payment terms begin. For consignment sales, revenue is recognized on the earlier of the actual product installation date or the “sunset” date.
Classification of Costs and Expenses	Classification of Costs and Expenses Cost of products sold includes raw materials, manufacturing labor, direct and indirect overhead costs, product freight, and depreciation of manufacturing plant and equipment. Warehousing costs incurred as a result of customer-specific delivery terms are also included in cost of products sold. Selling expenses include direct sales force salaries, commissions, travel and entertainment expenses and other expenses as well as agents’ commissions and fees, other warehousing costs, advertising costs and marketing costs. General and administrative expenses include costs relating to management and administrative staff such as employee compensation and benefits, travel and entertainment (non-sales), non-manufacturing facility occupancy costs, including rent expense and professional fees, as well as depreciation on non-manufacturing equipment and office supplies and expenses. Research and development expenses are comprised of engineering staff wages and associated fringe benefits, as well as the cost of prototypes, testing materials and non-capitalizable testing equipment.
Advertising Costs	Advertising Costs Selling expenses include advertising expenses of $0.9 million , $1.1 million and $1.2 million in 2017 , 2016 and 2015 , respectively. The Company expenses all advertising costs as incurred.
Translation of Financial Statements and Foreign Exchange	Translation of Financial Statements The reporting currency of the Company is U.S. Dollars. Assets and liabilities of non-U.S. operations are translated at year-end rates of exchange and the Consolidated Statements of Operations and Cash Flows are translated at the average rates of exchange during the year. Gains and losses resulting from translating non-U.S. Dollar denominated financial statements are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ deficit. Foreign Exchange Foreign exchange gains and losses arising out of transactions denominated in currencies other than a subsidiary’s functional currency are recorded in the Consolidated Statements of Operations. Net foreign exchange gains and losses are recorded in “Foreign exchange (loss) gain” and amounted to a (loss) gain of $(2,942) , $(383) and $1,872 for the years ended December 31, 2017 , 2016 and 2015 , respectively. Certain intercompany loans have been determined to be permanent, and accordingly, foreign exchange gains or losses related to such loans are recorded in accumulated other comprehensive loss within equity.
Derivatives and Hedging	Derivatives and Hedging As required by ASC Topic 815, Derivatives and Hedging (“Topic 815”), the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has not elected hedge accounting for any of its hedging activities. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting under Topic 815. See Note 6 "Derivatives and Hedging" for further discussion on the Company’s derivatives.
Freight Costs	Freight Costs The Company incurred $11.2 million , $10.3 million and $10.2 million in freight costs in the years ended December 31, 2017 , 2016 and 2015 , respectively. These costs are includes in cost of good sold in the Consolidated Income Statements.
Estimates	Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with maturities of three months or less when acquired. Short-term investments consist of time deposits or money market accounts at investment-grade banks.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at cost and do not bear interest. Bad debt provisions are included in general and administrative expense. The amounts recorded are derived based upon the general aging of receivables, specific customer credit history and payment trends and new business conditions.
Inventories	Inventories Inventories are generally valued at the lower of cost or market using the first-in, first-out ("FIFO") method. Raw materials are valued principally on a weighted average cost basis. The Company’s work in process and finished goods are specifically identified and valued based on actual inputs to production. Provisions are recorded as appropriate to write-down obsolete and excess inventory to estimated net realizable value. The process for evaluating obsolete and excess inventory often requires management to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be able to be sold in the normal course of business, while considering the general aging of inventory and factoring in any new business conditions.
Financial Instruments	Financial Instruments The carrying value of cash and cash equivalents, trade receivables, other current assets, accounts payable, notes payable and amounts included in accruals meeting the definition of a financial instrument under U.S. GAAP approximate fair value due to their short-term nature. The carrying value of long-term debt is less than its fair value (see Note 5 "Long-term Debt"). The Company determines estimated fair values based upon quoted market values where applicable or management estimates.
Long-lived Assets and Assets Held For Sale or Sold	Assets held for sale or sold During the first quarter of 2016, the Company determined that the Middletown, VA. facility, with a NBV of $3.0 million met the criteria under ASC Topic 360, Property, Plant, and Equipment (“Topic 360”) to be classified as held for sale. Accordingly, the related assets were reclassified out of property, plant and equipment to other assets in the Company's Consolidated Balance Sheet. This facility had not been sold as of December 31, 2017. During 2015, the Company determined that the Warwick, Quebec, Canada machine clothing facility, with a NBV of $0.5 million met the criteria under ASC Topic 360, Property, Plant, and Equipment (“Topic 360”) to be classified as held for sale. This facility had not been sold as of December 31, 2017. During 2013, a rolls facility in Charlotte, NC was classified as held for sale. This property had a carrying value of $0.5 million . Accordingly, the related assets were reclassified out of property, plant and equipment to other assets in the Company's Consolidated Balance Sheet. This facility was sold during 2017. Long-lived Assets Property and equipment Property and equipment are recorded at cost. Property and equipment acquired in connection with acquisitions are recorded at fair value as of the date of the acquisition, and subsequent additions are recorded at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: Asset Years Buildings and improvements 3-50 Machinery and equipment — Heavy 16-25 — General 13-15 — Light 6-12 — Molds, tools, office and computers 2-5
Impairment	Impairment The Company reviews its long-lived assets that have finite lives for impairment in accordance with Topic 360. This topic requires that companies evaluate the fair value of long-lived assets based on the anticipated un-discounted future cash flows to be generated by the assets when indicators of impairment exist to determine if there is impairment to the carrying value. Any change in the carrying amount of an asset as a result of the Company’s evaluation has been recorded as a component of income from operations in the Consolidated Statements of Operations. Impairment charges associated with restructuring are discussed in Note 11 "Restructuring Expense".
Intangible assets	Intangible assets Intangible assets consist of patents, licenses, trademarks, and customer relationships. Patents, licenses, trademarks, and customer relationships are amortized on a straight-line basis over their useful lives, which range from seven to fifteen years.
Goodwill	Goodwill The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, Intangibles—Goodwill and Other Intangible Assets (“Topic 350”). Topic 350 requires that goodwill and intangible assets that have indefinite lives not be amortized but, instead, must be tested at least annually for impairment or whenever events or business conditions warrant. The Company first assessed qualitative factors to determine whether it was more likely than not that the fair value of its reporting units were less than the carrying amounts as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company’s assessment is that the two-step goodwill impairment test was not necessary for the year ending December 31, 2017 and 2016 for either its clothing or rolls reporting units. If the qualitative factors had indicated that it was more likely than not that the fair value of the reporting units was less than its carrying amount, the Company would have tested goodwill for impairment at the reporting unit level using a two-step approach. Step 1 involves comparing the fair value of the Company’s reporting unit to its carrying amount. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the reporting unit carrying amount is greater than the fair value then the second step must be completed to measure the amount of impairment, if any. Step 2 calculates the implied fair value of goodwill by deducting the fair value of the net assets of the reporting unit from the fair value of the reporting unit as determined in Step 1. The implied fair value of goodwill determined in this step is compared to the carrying value of goodwill. If the implied fair value of goodwill is less than the carrying value of goodwill, an impairment loss is recognized equal to the difference. The Company performs an annual test for goodwill impairment as of October 1 at the reporting unit level. The Company has two reporting units: machine clothing and roll covers. For the purpose of performing the annual impairment test, the Company allocates all shared assets and liabilities to the reporting units based on the percentage of each reporting unit’s revenue to total revenue. Shared operating expenses are allocated to the reporting unit to the extent necessary to allow them to operate as independent businesses. To determine if impairment exists, the fair value of each reporting unit is compared to its carrying value. The fair value of the Company’s reporting unit is determined by using a weighted combination of both a market multiple approach and an income approach. The market multiple approach utilizes the Company’s and its competitors’ proprietary information that is used to value its reporting units. The income approach is a present value technique used to measure the fair value of future cash flows produced by each reporting unit. During the fourth quarter of 2016, the Company voluntarily changed the date of its annual goodwill impairment testing from December 31, the last day of the fiscal year, to October 1. The voluntary change in accounting principle related to the annual testing date did not delay, accelerate or avoid an impairment charge. This change was not applied retrospectively, as it would have required application of significant estimates and assumptions with the use of hindsight. Accordingly, the change was applied prospectively.
Stock-Based Compensation	Stock-Based Compensation The Company records stock-based compensation expense in accordance with ASC Topic 718, Compensation—Stock Compensation (“Topic 718”) which generally requires that such transactions be recognized in the statement of operations based on their fair values at the date of grant. See Note 10 "Long-term Incentive and Stock-Based Compensation" for further discussion.
Net (Loss) Income Per Common Share	Net (Loss) Income Per Common Share Net (loss) income per common share has been computed and presented pursuant to the provisions of ASC Topic 260, Earnings per Share (“Topic 260”). Net (loss) income per share is based on the weighted-average number of shares outstanding during the period. As of December 31, 2017 , 2016 and 2015 , the Company had outstanding restricted stock units (“RSUs”) (See Note 10 "Long-term Incentive and Stock-Based Compensation"). Diluted average shares outstanding were computed using (i) the average market price for time-based RSUs and (ii) the actual grant date market price for non-employee director RSUs. The calculation of diluted earnings per share excludes the Company’s performance-based RSUs that are based on Adjusted EBITDA targets whose performance criteria have not been contingently achieved and therefore the RSUs have not been issued or are not contingently issuable. For the years ended December 31, 2017 , 2016 , and 2015 the dilutive effect of potential future issuances of common stock underlying the Company’s RSUs was excluded from the calculation of diluted average shares outstanding because their effect would have been anti-dilutive as the Company incurred a net loss.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC Topic 740 , Income Taxes (“Topic 740”), which requires the recognition of deferred tax assets and liabilities for the expected future consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets, representing future tax benefits, are reduced by a valuation allowance when the determination can be made that it is “more likely than not” that all or a portion of the related tax asset will not be realized. The deferred tax provision or benefit represents the annual change in deferred tax assets and liabilities, excluding any amounts accounted for as components of goodwill or accumulated other comprehensive loss, including the effect of foreign currency translation thereon. While the Company believes it has adequately provided for its income tax receivable or liabilities and its deferred tax assets or liabilities in accordance with Topic 740 income tax guidance, adverse determination by taxing authorities or changes in tax laws and regulations could have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. Income taxes are further discussed in Note 7.
Warranties	Warranties The Company offers warranties on certain rolls products that it sells. The specific terms and conditions of these warranties vary depending on the product sold, the country in which the product is sold and arrangements with the customer. The Company estimates the costs that may be incurred under its warranties and records a liability for such costs. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction. The Company periodically assesses the adequacy of its recorded warranty claims and adjusts the amounts as necessary.
Commitments and Contingencies	Commitments and Contingencies The Company provides accruals for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. Costs accrued have been estimated based on consultation with legal counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes.
Acquisitions	Acquisitions Acquired businesses are accounted for using the acquisition method of accounting (ASC 805-10-50), which requires that assets acquired and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. Transaction costs and costs to restructure the acquired company are expensed as incurred. The operating results of the acquired business are reflected in our consolidated financial statements after the date of acquisition.
New Accounting Standards	New Accounting Standards In February 2018, the FASB issued Accounting Standards Update No 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02). The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption of the amendments in this update is permitted, including adoption in any interim period, for public business entities for reporting periods for which financial statements have not yet been issued and for all other entities for reporting periods for which financial statements have not yet been made available for issuance. The Company is in the process of evaluating this accounting standard update. In August 2017, the FASB issued Accounting Standards Update No 2017-12, Derivative and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12). The amendments in ASU 2017-12 provide 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. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted in any interim period after issuance of the update. The Company is in the process of evaluating this accounting standard update. In May 2017, the FASB issued Accounting Standards Update No 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"). The amendments in ASU 2017-09 provide 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. The amendments in ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of this guidance is not expected to have a material impact on the Company's financial statements. In March 2017, the FASB issued Accounting Standards Update No 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 will change how employers that sponsor defined benefit pension and/or other post-retirement benefit plans present the net periodic benefit cost in the income statement. Employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. Employers will present the other components of the net periodic benefit cost separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. These components will not be eligible for capitalization in assets. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods therein. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The guidance provides a practical expedient for disaggregating the service cost component and other components for comparative periods. The adoption of this guidance in 2018 is not expected to have a material impact on net income, and financial position. No changes to cash flows are expected from adoption. In January 2017, the FASB issued Accounting Standards Update No 2017-04, Intangibles—Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under Accounting Standards Codification (ASC) 350. The FASB issued new guidance that eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of today’s goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). The standard has tiered effective dates, starting in 2020 for calendar-year public business entities that meet the definition of an SEC filer. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is in the process of evaluating this accounting standard update. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"). ASU 2016-16 eliminates the exception to the principle in ASC 740, for all intra-entity sales of assets other than inventory, to be deferred, until the transferred asset is sold to a third party or otherwise recovered through use. This standard is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update No 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 clarifies how entities should classify certain cash receipts and cash payments in the statement of cash flows and amends certain disclosure requirements of ASC 230. The guidance will generally be applied retrospectively and is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those years. For all other entities, it is effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The adoption of this guidance is not expected to have a material impact on the Company's financial statements. In February of 2016, the FASB issued Accounting Standards Update No 2016-02 Leases ("ASU 2016-02"). ASU 2016-02 includes final guidance that requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to today’s accounting. The guidance also eliminates today’s real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. All entities will classify leases to determine how to recognize lease-related revenue and expense. Classification will continue to affect amounts that lessors record on the balance sheet. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. They have the option to use certain relief. Full retrospective application is prohibited. ASU 2016-02 is effective for public companies with annual periods beginning after December 15, 2018, and interim periods within those years. For all other entities, it is effective for annual periods beginning after December 15, 2019, and interim periods the following year. Early adoption is permitted for all entities. The Company has commenced a comprehensive project plan to direct the implementation of the new leases standard and an assessment of the impact to business processes. In May of 2014, the FASB issued Accounting Standard Update No. 2014-09 Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that the Company identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when it satisfies the performance obligations. The Company will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is required to be adopted in January of 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. The Company intends to adopt the new standard using the modified retrospective transition method effective January 1, 2018 and the adoption of this guidance is not expected to have a material impact on the Company's financial statements.
