Significant Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 1 – Significant Accounting Policies Principles of consolidation: All majority-owned subsidiaries are included in the Company’s consolidated financial statements, with appropriate elimination of intercompany balances and transactions. Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company’s share of net income or losses in these investments in associated companies is included in the C onsolidated Statement s of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary. See Note 13 of Notes to Consolidated Financial Statements. The Financial Accounting Standards Board’s (“FASB’s”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabil ities and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance. Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and associated comp anies are translated into U.S. d ollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resultin g from this process are recorded directly in equity as accumulated other comprehensive (loss) income (“AOCI”) and will be included as income or expense only upon sale or liquidation of the underlying investment. Generally, all of the Company’s non-U.S. su bsidiaries use their local currency as their functional currency. Cash and cash equivalents: The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company consid ers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has not experienced losses from the aforementioned investments. Inventories: Inventories are valued at the lower of cost or net realizab le val ue, and are valued using the first-in, first-out (“FIFO”) method. See Note 10 of Notes to Consolidated Financial Statements. Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line me thod on an individual asset basis over the following estimated useful lives: building s and improvements , 10 to 45 years; and machinery an d equipment, 1 to 15 years. The carrying value s of long-lived assets are evaluate d whenever changes in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future cash fl ows. Upon sale or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in the Consolidated Statements of I nco me. Expenditures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenan ce are expensed when incurred. See Note 11 of Notes to Consolidated Financia l Statements. Capitalized software: The Company capitalizes certain costs in connection with developing or obtaining software for internal use , depending on the associated project . These costs are amortized over a period of 3 to 5 year s once the assets are ready for their intended use. In connection with the implementations and upgrades to the Company’s global transaction, consolidation and other related systems, approximatel y $1.4 million and $1.3 million of net costs were capitalized in property, plant and equipment on the Company’s December 31, 2016 and 2015 Consolidated Balance Sheets, respectively. Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets a nd indefinite-lived intangible assets at fair value at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering ev ents indicate potential impairment. Definite-lived intangible assets are amortized over their estimated useful lives, gen erally for periods ranging from 4 to 20 years. The Company continually evaluates the reasonableness of the useful l ives of these assets, consistent with the discussion of long-lived assets, above. See Note 12 of Notes to Consolidated Financial Statements. Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. For the Company, t his generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fees and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is r easonably assured. As part of the Company’s chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferre d under arrangements resulting in net reporti ng totaled $43.5 million, $48.6 million and $46.8 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Accounts receivable and allowance for doubtful accounts: Trade accounts receivable subject the Company to credit risk. Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses with its existing accounts receivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount outstanding at the bankruptcy filing date. However, initially establishing a reserve and the amount thereto is dependent on the Company’s evaluation of likely proceeds to be received from the bankruptcy process, which could result in the Company recognizing minimal or no reserve at the date of bankruptcy. Large and/or financially distress ed customers are generally reserved for on a specific review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account b alances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers. During the year ended December 31, 2016 , the Company’s five largest customers accounted for approximately 19% of its consolidated net s ales with the largest customer accounting for approximately 8% of the Company’s consolidated net sales. See Note 9 of Notes to Con solidated Financial Statements. Research and development costs: Research and development costs are expensed as incurred and are included in selling, general and administrative expenses (“SG&A”) . Research and development exp enses were $22.5 million, $22.1 million and $22.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liabi lity has been incurred and the amount of the liability can be reasonably estimated. If there is a range of estimated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capac ity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or preven t contamination in the future. See Note 22 of Notes to Consolidated Financial Statements. Asset retirement obligations: The Company follows the FASB’s guidance regarding asset retirement obligations, which addresses the accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB’ s guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within t he control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis. At December 31, 2016 an d 2015 , the Company had limited exposure to such obligations and had immaterial liabilities recorded for such on its Consolidated Balance Sheets. Pension and other postretirement benefits: The Company maintains various noncontributory retirement pl ans, the largest of which is in the U.S., covering a portion of its employees in the U.S. and certain other countries. The plans of the Company’s subsidiaries in t he Netherlands, the United Kingdom (“U.K.”) , Mexico and Sweden are subject to the provisions of FASB’s guidance regarding employers’ accounting for defined benefit pension plans. The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments’ plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost. The Company’s U.S. pension plan year ends on November 30 and th e measurement date is December 31. The measurement date for the Company’s other postretirement benefits plan is December 31. The Company’s global pension investment polic ies are designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. The Company’s investment horizon is gen erally long term, and, accordingly, the target asset allocations encompass a long- term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in intermediate plan distributions, and the total return portfolio is expecte d to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company’s investment guidelines prohibi t use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specifically addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging. The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships . The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitored with an overall expectation that plan assets will meet or exceed bench mark performance over rolling five-year periods. The Company’s pension committee, as authorized by the Company’s Board of Directors, has discretion to manage the assets within established asset allocation ranges approved by senior management of the Compan y. As of December 31, 2016 , the plan’s investments were in compliance with all approved ranges of asset allocations. See Note 17 of Notes to Consolidated Financial Statements. Comprehensive income (loss): The Company presents other comprehensi ve income (loss) in its Statement s of Comprehensive Income. The Company follows the FASB’s guidance regarding the disclosure of reclas sifications from AOCI which requires the disclosure of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by such reclassifications. See Note 19 of Notes to Consolidated Financial Statements. Income taxes and uncertain tax positions: The provision for income taxes is determined using the asse t and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The FASB’s guidance regarding accounting for uncertainty in inco me taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the ben efits of tax positions will be more likely than not sustained upon audit based upon the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the ben efit in the financial statements. Additionally, the Company monitors and adjusts for derecognition, classification, and penalties and interest in interim periods, with appropriate disclosure and transition thereto . A lso , the amount of interest expense an d income related to uncertain tax positions is computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company’s continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Finally, when applicable, t he Company net s its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would apply if the uncertain tax position were settled for the presumed amount at the balance sheet date. See N ote 7 of Notes to Consolidated Financial Statements. Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivat ive instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. When used, the Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hedges, the effective portion of any hedge would be reported in AOCI until it was cleared to earnings durin g the same period in which the hedged item affected earnings. The Company currently uses no derivative instruments designated as hedges and , also, has not entered into derivative contracts for trading or speculative purposes. Fair value measurements: The Company utilizes the FASB’s guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into thr ee broad levels. See Notes 17 and 21 of Notes to Consolidated Financial Statements. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity's own assumptions. Stock-based compensation: The Company applies the FASB’s guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Restricted stock awards and r estricted s tock u nits (“RSU”) issued under the LTIP program are generally subject to time vesting over a one to five-year period. In ad dition, as part of the Company’s Global Annu al Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated. See Note 5 of Notes to Con solidated Financial Statements. Earnings per share: The Company follows the FASB’s guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method. See Note 8 of Notes to Consolidated Financial Statements. Segments: The Company’s reporting segments are the same as the Company’s operating segments. The Company’s reportable operating segments evidence the structure of the Company’s internal organization, the method by which the Company’s resources are allocated and the manner by which the Company assesse s its performance. The Company’s reportable operating segments are organized by geography as follows: (i) North America, (ii) Europe, Middle East and Africa (“EMEA”), (iii) Asia/Pacific and (iv) South America. See Note 4 of Notes to Consolidated Fina ncial Statements. Business combinations: The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets and assumed liabilities at their respective acquisition date estimated fair values. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. The determination of the estimated fair value of assets acquired and liabi lities assumed requires significant estimates and assumptions. Based on the assessment of additional information during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the estimated fair value of assets acquired and liabilities assumed. See Note 20 of Notes to Consolidated Financial Statements. Restructuring activities: Restructuring programs consist of employee severance, rationalization of manufacturing or other facilities and other related items. To account for such programs , the Company applies FASB’s guidance regarding exit or disposal cost obligations. This guidance requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, is estimable, and payment is probable. See Note 3 of Notes to Consolidated Financial Statements. Reclassifications : Certain information has been reclassified to conform to the current year presentation. During the first quarter of 2016 , the Company revised its Consolidated Balance Sheet for December 31, 2015, reducing non-current deferred tax assets and non-current deferred tax liabilities by $3.6 million each, to correct for offsetting deferred tax balances within related taxing jurisd ictions. The Company considers such revision to be immaterial and the revision had no impact on reported equity, net income or net cash provided by operating activities. In addition, during the fourth quarter of 2016, the Company early adopted an account ing standard update issued by the FASB in November 2015 regarding the classification of deferred taxes on the balance sheet. The Company applied the guidance in this accounting standard update retrospectively. See Note 2 of Notes to Consolidated Financia l Statements. Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilitie s and disclosure of contingencies at the date of the financial statements and the reported amounts of net sales and expens es during the reporting period. Actual results c ould differ from such estimates.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Description Of New Accounting Pronouncements Not Yet Adopted [Text Block]	The FASB issued an accounting standard update in January 2017, simplifying the test for goodwill impairment by eliminating the Step 2 computation. The accounting standard update modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The guidance removes the requirement to determ ine a goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The guidance within thi s accounting standard update should be applied on a prospective basis, and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairmen t tests performed on testing dates after January 1, 2017. The Company is still evaluating the guidance but currently anticipates early adoption of the accounting standard update for its next annual goodwill impairment test during 2017, and does not expect a material impact to its financial statements. The FASB issued an accounting standard update in January 2017, amending and adding certain requirements regarding disclosure of the impact that specific recently issued accounting standards will have on the financial statements of a registrant when such standards are adopted in a future period. This update is based on recent SEC announcements regarding the staff’s view that a registrant should evaluate accounting standard updates that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those accounting standard updates on the financial statements when adopted, particularly regarding the accounting for and disclosure of revenue rec ognition. The requirements of this accounting standard update are effective immediately and the Company has reviewed and considered this accounting standard update when revising certain disclosures, as applicable. The FASB issued an accounting standard update in January 2017 to clarify the definition of a business with the objective of adding guidance to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this accounting standard update provide a more robust framework to use in determining when a set of assets and activities is a business. The guidance within this accounting standard update is effective for annual and interim periods beginning after Decem ber 15, 2017. Early adoption is permitted in limited circumstances, and the amendments in this accounting standard update should be applied prospectively, with no disclosures required at transition. The Company does not currently meet the criteria for ea rly application of the amendments and therefore has not early adopted the guidance. The Company will evaluate the potential impact of this guidance on future transactions, as applicable. The FASB issued an accounting standard update in November 2016 req uiring that the statement of cash flows explain both the change in the total cash and cash equivalents, and, also, the amounts generally described as restricted cash or restricted cash equivalents. This will require amounts generally described as restrict ed cash or restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning and ending amounts shown on the statement of cash flows. The guidance within this accounting standard update is effective for annual and inter im periods beginning after December 15, 2017. Early adoption is permitted and the guidance requires application using a retrospective transition method to each period presented when adopted. While permitted, the Company has not early adopted the guidance and is currently evaluating the appropriate implementation strategy. Adoption of the guidance will not have an impact on the Company’s earnings or balance sheet but will result in changes to certain disclosures within the statement of cash flows, notably cash flows from investing activities. The FASB issued an accounting standard update in August 2016 to standardize how certain transactions are classified in the statement of cash flows. Specific transactions covered by the accounting standard update incl ude debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate a nd bank owned life insurance policies, distributions received from equity method investments and beneficial interest in securitization transactions. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. While permitted, the Company has not early adopted the gu idance and is currently evaluating the appropriate implementation strategy. Adoption of the guidance will not have an impact on the Company’s earnings or balance sheet but may result in certain reclassifications on the statement of cash flows, including r eclassifications between cash flows from operating activities, investing activities and financing activities, respectively. The FASB issued an accounting standard update in March 2016 involving several aspects of the accounting for share-based payment tran sactions, including the income tax consequences, classification of awards as either equity or liabilities, use of a forfeiture rate, and classification on the statement of cash flows. The guidance within this accounting standard update is effective for an nual and interim periods beginning after December 15, 2016. Early adoption is permitted, however, if early adoption is elected, all amendments in the update must be adopted in the same period. When adopted, application of the guidance will vary based on each aspect of the update, including adoption under retrospective, modified retrospective or prospective approaches. The Company has not early adopted and is currently evaluating the potential impact of this guidance and an appropriate implementation stra tegy. The Company will adopt the guidance in this accounting standard update during the first quarter of 2017, as required. The FASB issued an accounting standard update in February 2016 regarding the accounting and disclosure for leases. Specificall y, the update will require entities that lease assets to recognize the assets and liabilities for the rights and obligations created by those leases on the balance sheet, in most instances. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2018, and should be applied on a modified retrospective basis for the reporting periods presented. Early adoption is permitted. The Company has not early adopted and is currently evaluating the potential impact of this guidance and an appropriate implementation strategy. The Company has begun its impact assessment, including taking an inventory of its outstanding leases globally. While the Company’s evaluation of this guidance is in the early s tages, the Company currently expects adoption of this guidance to have an impact on its balance sheet. The FASB issued an accounting standard update in November 2015 regarding the classification of deferred taxes on the balance sheet. The update requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The update does not change the existing requirement that only permits offsetting within a jurisdiction. The guidan ce within this accounting standard update is effective for annual and interim periods beginning after December 15, 2016, and may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. Early adoption is permitted. During the fourth quarter of 2016, the Company early adopted the guidance of this accounting standard update and applied the guidance in this accounting standard update retrospectively. Including the first quarter of 2016 revision noted in Note 1 of Not es to Consolidated Financial Statements, adoption of the accounting standard update resulted in a reclassification to the Company’s Consolidated Balance Sheet as of December 31, 2015, reducing current deferred tax assets by $7.8 million, current deferred t ax liabilities by less than $0.1 million, and non-current deferred tax liabilities by $4.7 million, and increasing non-current deferred tax assets by $3.0 million. Adoption of the guidance had no impact on the Company’s earnings or cash flow. See Note 7 of Notes to Consolidated Financial Statements. The FASB issued an accounting standard update in July 2015 regarding simplifying the measurement of inventory. The guidance is applicable for entities that measure inventory using the FIFO or average cost met hods. Specifically, the update requires that inventory be measured at lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in this update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. This guidance should be applied prospectively with early adoption permitted. During the first quarter of 2016, the Company elected to early adopt this guidance without a material impact. The FASB issued an accounting standard update in May 2015 regarding the required disclosures for entities that elect to measure the fair value of certai n investments using the net asset value (“NAV”) per share (or its equivalent) practical expedient in accordance with the fair value measurement authoritative guidance. The update removes the requirement to categorize within the fair value hierarchy, and a lso limits the requirement to make certain other disclosures, for all such investments. The amendments in this update are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, and should be applied on a retrospective basis for the periods presented. Early adoption was permitted. During the first quarter of 2016, the Company adopted this guidance without a material impact. See Note 17 of Notes to Consolidated Financial Statements. The FASB issued an accounting standard update in April 2015 regarding the presentation of debt issuance costs on the balance sheet. The update requires capitalized debt issuance costs be presented on the balance sheet as a reduction to debt, rather than recorded as a sep arate asset. The amendments in this update are effective for annual and interim periods beginning after December 15, 2015 and should be applied on a retrospective basis for the periods presented. Early adoption was permitted. Also, in June 2015, the SEC staff announced that the guidance within this accounting standard update was not applicable to revolving debt arrangements or credit facilities. During the first quarter of 2016, the Company adopted this guidance without a material impact. The FASB issued an accounting standard update in May 2014 regarding the accounting for and disclosure of revenue recognition. Specifically, the update outlined a single comprehensive model for entities to use in accounting for revenue arising from contrac ts with customers, which will be common to both U.S. GAAP and International Financial Reporting Standards (“IFRS”). The guidance was effective for annual and interim periods beginning after December 15, 2016, and allowed for full retrospective adoption of prior period data or a modified retrospective adoption. Early adoption was not permitted. In August 2015, the FASB issued an accounting standard update to delay the effective date of the new revenue standard by one year, or, in other words, to be effect ive for annual and interim periods beginning after December 15, 2017. Entities will be permitted to adopt the new revenue standard early but not before the original effective date. During 2016, the FASB issued a series of accounting standard updates to c larify and expand on the implementation guidance, including principal versus agent considerations, identification of performance obligations, licensing, other technical corrections and adding certain practical expedients. The amendments in these 2016 upda tes do not change the core principle of the previously issued guidance in May 2014. During 2016, the Company reviewed its historical accounting policies and practices to identify potential differences with the requirements of the new revenue standard, as it relates to the Company’s contracts and sales arrangements. As of December 31, 2016, the Company has progressed its impact assessment for the implementation of the new revenue recognition guidance, including contract reviews and preliminary consideratio ns for the Company’s future financial reporting and disclosure requirements. While the impact assessment continues, the Company has not yet selected a method, and, also, has yet to conclude on the impact of the accounting standard update. The Company cur rently expects its determination will be near completion during the first half of 2017. The Company is still assessing the materiality and the potential impact on its earnings, cash flows, and balance sheet, however; the Company does expect its adoption t o increase the amount and level of disclosures concerning the Company’s net sales.

Restructuring And Related Activities [Abstract]
Restructuring And Related Activities Disclosure [Text Block]	Note 3 – Restructuring and Related Activities In response to continued weak economic conditions and market declines in many regions, Quaker’s management approved a global restructuring plan (the “2015 Program”) in the fourth quarter of 2015 to reduce its operating costs. The 2015 Program included the re-organization of certain commercial functions, the consolidation of certain distribution, laboratory and administrative offices, and other related severance charges. In addition to these actions, durin g the fourth quarter of 2015 the Company made a decision to make available-for-sale certain technology of one of its existing businesses, which also resulted in employee severance and $0.3 million of intangible assets being reclassified to other current as sets as of December 31, 2015. During the fourth quarter of 2016, the Company made a decision to no longer market or make available-for-sale this technology, which resulted in $0.3 million of other current assets being reclassified back to intangible asset s as of December 31, 2016. The 2015 Program include d provisions for the reduction of total headcount by approximately 65 employees globally. As a result of this program, the Company recognized a $6.8 million, or $0.36 per diluted share, restructuring ch arge in the fourth quarter of 2015. Employee separation costs varied depending on local regulations within certain foreign countries and included severance and other benefits. The Company substantially completed all of the initiatives under the 2015 Prog ram in 2016 and settlement of these charges occurred primarily in 2016 as well. During the fourth quarter of 2016, the Company recognized a restructuring credit of $0.4 million, or $0.02 per diluted share, in connection with the 2015 Program, due to custo mary and routine adjustments to initial estimates for employee separation costs, as well as the reversal of certain accrued employee separation costs as a result of the change in available-for-sale technology, noted above. At this time, the Company does n ot expect to incur material additional restructuring charges or credits under the 2015 Program . Restructuring activity recognized in each reportable operating segment in connection with the 2015 Program during the years ended December 31, 2016 an d 2015 is as follows: North South America EMEA Asia/Pacific America Total Accrued restructuring as of December 31, 2014 $ — $ — $ — $ — $ — Restructuring charges 2,025 4,390 338 37 6,790 Cash payments (158) (130) (202) — (490) Currency translation adjustments — 5 (1) (1) 3 Accrued restructuring as of December 31, 2015 $ 1,867 $ 4,265 $ 135 $ 36 $ 6,303 Restructuring credits — (439) — — (439) Cash payments (1,671) (3,404) (138) (39) (5,252) Currency translation adjustments — 52 3 3 58 Accrued restructuring as of December 31, 2016 $ 196 $ 474 $ — $ — $ 670

Consistent with prior years, the Company granted stock options under its LTIP plan that are subject only to time vesting over a three-year p eriod in the first quarters of 2013 , 2014 , 2015 and 2016 . For the purposes of determining the fair value of stock option awards, the Company uses t he Black-Scholes option pricing model and the assumptions set forth in the table below: 2016 2015 2014 2013 Number of stock options granted 67,444 38,698 37,048 29,302 Dividend yield 1.49 % 1.55 % 2.00 % 2.49 % Expected volatility 28.39 % 36.32 % 43.34 % 57.28 % Risk-free interest rate 1.08 % 1.22 % 1.22 % 0.63 % Expected term (years) 4.0 4.0 4.0 4.0 These awards are being amortized on a straight-line basis over the respective vesting period of each award.

Employee Stock Purchase Plan In 2000, the Board adopted an Employee Stock Purchase Plan (“ESPP”) whereby employees may purchase Company stock through a payroll deduction plan. Purchases are made from the plan and credited to each participant’s a ccount at the end of each month ( the “Investment Date” ). The purchase price of the stock is 85 % of the fair market value on the Investment Date. The plan is compensatory and the 15 % discount is expensed on the Investment Date. All employees, including officers, are eligible to participate in this plan. A participant may withdraw all uninvested payment balances credited to a participant’s account at any time . An employee whose stock ownership of the Company exceeds five percent of the outstanding common stock is not eligible to participate in this plan. 2013 Director Stock Ownership Plan In 2013, the Company adopted the 2013 Director Stock Ownership Plan (the “Plan”) , to encourage the Directors to increase their investment in the Company , which was approved at the Company’s May 2013 shareholders’ meeting. The Plan authorizes the issuance of up to 75,000 shares of Quaker common stock in accordance with the terms of the Plan in payment of all or a portion of the annual cash retainer payable to each of the Company’s non-employee directors in 2013 and subsequent years during the term of the Plan. Under the Plan, each director who, on May 1 of the applicable calendar year, owns less than 400% of the annual cash retainer for the applicable calendar year, divided by the average of the closing price of a share of Quaker Common Stock as reported by the composite tape of the New York Stock Exchange for the previous calendar year (the “Threshold Amount”), is required to receive 75% of the annual cash retainer in Quaker common stock and 25% of the retainer in cash, unless the director elects to receive a greater per centage of Quaker common stock, up to 100% of the annual cash retainer for the applicable year. Each director who owns more than the Threshold Amount may elect to receive common stock in payment of a percentage (up to 100%) of the annual cash retainer. The annual retainer is $0.1 million and the retainer payment date is June 1.

In addition, the Company has foreign tax loss carryforwards of $8.2 million of which $0.2 million expires in 2018 , $0.2 million expires in 2019 , $0.1 million expires in 2020 , $0.5 million expires in 2021 and $0.8 million expires thereafter . T he remaining foreign tax losses have no expiration dates. A partial valuation allowance ha s been established with respect to the tax benefit of these losses for $0.8 million. U.S. income taxes have not been provided on the undistributed earnings of non-U.S. subsidiaries because it is the Company’s intention to continue to reinvest th ese earnings in those subsidiaries to support growth initiatives. U.S. and foreign income taxes that would be payable if such earnings were distributed may be lower than the amount computed at the U.S. statutory rate due to the availability of tax credits . The amount of such undistributed earnings at December 31, 2016 was approximately $220 million . Any income tax liability, which might result from ultimate remittance of these earnings, is expected to be substantially offset by foreig n tax credits. It is currently impractical to estimate any such incremental tax expense. As of December 31, 2016 , the Company’s cumulative liability for gross unrecognized tax benefits was $6.2 million . The Company had accrued $1.6 million for cumulative penalties and $0.7 million for cumulative interest at December 31, 2016 . As of December 31, 2015 , the Company’s cumulative liability for gross unrecognized tax benefits was $11.0 million . The Company had accrued $1.9 million for cumulative penalt ies and $1.5 million for cumulative interest at December 31, 2015 . The Company continues to recognize interest and penalties associated with uncertain tax p ositions as a component of tax (benefit) expense on income before equity in net i ncome of associated companies in its Consolidated Statement s of Income. The Company recognized ($0.2) million for penalties and ($0.7) million for interest (net of expirations and settlements) in its 2016 Consolidated Statement of In come, $0.2 million for penalties and ($0.2) million for interest (net of expirations and settlements) in its 2015 Consolidated Statement of Income and less than ($0.1) million for both penalties and interest , respectively, ( net of expirations and settlements) in its 2014 Consolidated Statement of Income. The Company estimates that during the year ending December 31, 2017 , it will reduce its cumulative liability for gross unrecognized tax benefits by approxima tely $1.0 to $1.1 million due to the expiration of the statute of limitations with regard to certain tax positions. This estimated reduction in the cumulative liability for unrecognized tax benefits does not consider any increase in liabil ity for unrecognized tax benefits with regard to existing tax positions or any increase in cumulative liability for unrecognized tax benefits with regard to new tax positions for the year ending December 31, 2017 . The Company and its subsidiaries are subject to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions. Tax years that remain subject to examination by major tax jurisdictions include Brazil from 2000, Italy from 2007, the Netherlands from 2010 , the United Kingdom from 2011, Spain and China from 2012, the United States from 2013, and various domestic state tax jurisdictions from 1993. In the fourth quarter o f 2015, the D utch tax authorities assessed the Company’s subsidiary, Quaker Chemical B.V., for additional income taxes related to the 2011 tax year and Quaker Chemical B.V. filed a protest of such assessment. During the third quarter of 2016 , the Company settled with the Dutch tax authorities for matters related to transfer pricing issues for 2011, 2012, 2013, 2014, and 2015, with no change to the income tax returns as filed. In the first quarter of 2016, the French tax authorities gave notice that they were auditing the Company’s subsidiary Quaker Chemical S.A, and subsequently, during t he second quarter of 2016, gave notice that they closed the audit with no additional tax assessed. As previously reported , t he Italian tax authorities have assessed additional tax due from the Company’s subsidiary, Quaker Italia S.r.l., relating to the ta x years 2007, 2008, 2009 and 2010. In the fourth quarter of 2016, the Italian tax authorities assessed Quaker Italia S.r.l. for additional tax due relating to the tax years 2011, 2012, and 2013. As of December 31, 2016 , the Company believes it has adequate reserves, where merited, for uncertain tax positions with respect to all of these audits. A reconciliation of the beginning and ending amounts of unrecognized tax benefits for the years ended December 31, 2016 , 2015 and 2014 , respectively, is as follows: 2016 2015 2014 Unrecognized tax benefits at January 1 $ 11,032 $ 11,845 $ 12,596 Decrease in unrecognized tax benefits taken in prior periods (869) (416) (93) Increase in unrecognized tax benefits taken in current period 1,921 2,512 2,678 Decrease in unrecognized tax benefits due to lapse of statute of limitations (5,744) (1,924) (2,078) Decrease due to foreign exchange rates (100) (985) (1,258) Unrecognized tax benefits at December 31 $ 6,240 $ 11,032 $ 11,845 The amount of unrecognized tax benefits above that, if recognized, would impact the Company’s tax expense and effective tax rate is $1.8 million , $1.1 million and $1.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.

Investments in Associated Companies [Abstract]
Investments in Associated Companies [Text Block]	As of December 31, 2016 , the Company held a 50% investment in and had significant influence over Kelko Quaker Chemical, S.A. (Venezuela), Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical S.A. (Panama) and held a 33% investment in and had significant influence over Primex, Ltd. (Barbados). The carrying amount of the Company’s equity investments at December 31, 2016 was $22.8 million , which includes its investments of $17.1 million in Primex , Ltd. (Barbados); $5.2 million in Nippon Quaker Chemical, Ltd. (Japan); $0.3 million in Kelko Quaker Chemical, S.A. (Panama) ; and $0.2 million in Kelko Quaker Chemical, S.A. (Venezuela). Venezuela’s economy has been considered hyper inflationary under U.S. GAAP since 2010, at which time the Company’s Venezuela equity affiliate, Kelko Quaker Chemical, S.A. (“Kelko Venezuela”), changed its functional currency from the bolivar fuerte (“BsF” ) to the U.S. dollar. Accordingly, all gains and losses resulting from the remeasurement of Kelko Venezuela’s monetary assets and liabilities to published exchange rates are required to be recorded directly to the Consolidated Statements of Income. As of December 31, 2014, there were three legally available exchange rates in Venezuela, the CADIVI (or the official rate, 6.3 BsF per U.S. dollar), the SICAD I and the SICAD II. Kelko Venezuela had access to the CADIVI for imported goods, had not been invited to participate in any SICAD I auctions and had limited access to the SICAD II mechanism. Accordingly, the Company measured its equity investment and other related assets with Kelko Venezuela at the CADIVI exchange rate at December 31, 2014. D uring the s econd quarter of 2014, the Company recorded a charge of $0.3 million, or $0.02 per diluted share, related to the conversion of certain BsF to U.S. dollars on the historical SICAD II exchange. During the first quarter of 2015, the Venezuela government ann ounced changes to its foreign exchange controls. There continued to be three exchange mechanisms, however, they consisted of the CADIVI, a combined SICAD I and SICAD II auction mechanism (the “SICAD”) and a newly created, marginal currency system (the “SI MADI”). In light of the first quarter of 2015 changes to Venezuela’s foreign exchange controls and the on-going economic challenges in Venezuela, the Company re-assessed Kelko Venezuela’s access to U.S. dollars, the impact on the operations of Kelko Venez uela, and the impact on the Company’s equity investment and other related assets, which resulted in revaluing its equity investment in Kelko Venezuela and other related assets to the SIMADI exchange rate of approximately 193 BsF per U.S. dollar as of March 31, 2015 . This resulted in a charge of $ 2.8 million, or $ 0.21 per diluted share, recorded in the first quarter of 2015. During the first quarter of 2016, the Venezuela government announced further changes to its foreign exchange controls, including eliminating the CADIVI, SICAD and SIMADI exchange rate mechanisms and replacing them with a new dual foreign exchange rate system, which consists of a protected “DIPRO” exchange rate, with a rate fixed at 10 BsF per U.S . dollar and, also, a floating supplementary market exchange rate known as the “DICOM.” The DIPRO rate is only available for payment of certain imports of essential goods in the food and health sectors while the DICOM governs all other transactions not co vered by the DIPRO. In light of these changes to the foreign exchange controls during the first quarter of 2016, the Company again re-assessed Kelko Venezuela’s access to U.S. dollars, the impact on the operations of Kelko Venezuela, and the impact on the Company’s equity investment and other related assets. The Company did not believe it had access to the DIPRO and, therefore, believed the DICOM to be the exchange rate system available to Kelko Venezuela. As of March 31, 2016, the published rate for the DICOM was approximately 273 BsF per U.S. dollar, which resulted in a currency conversion charge of $0.1 million, or $0.01 per diluted share in the first quarter of 2016. As of December 31, 2016 , the Company’s equity investment in Kelko Venezuela was valued at the DICOM exchange rate of approximately 673 BsF per U.S. dollar.

The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. The proceeds of the settlement and release agreements have been deposited into interest bearing accounts whic h earned less than $0.1 million in the years ended December 31, 2016 and 2015 , respectively, offset by $1.0 million and $0.8 million of net payments in 2016 and 2015 , respectively. Due to the restricte d nature of the proceeds, a corresponding deferred credit was established in “Other non-current liabilities” for an equal and offsetting amount, and will remain until the restrictions lapse or the funds are exhausted via payments of claims and costs of def ense.

Debt [Abstract]
Debt [Text Block]	Note 16 – Debt Debt as of December 31, 2016 and 2015 includes the following : 2016 2015 Credit facilities $ 47,948 $ 62,884 Industrial development bonds 15,000 15,000 Municipality-related loans 3,470 4,098 Other debt obligations (including capital leases) 58 119 66,476 82,101 Short-term debt (including capital leases) (58) — Current portion of long-term debt (649) (662) $ 65,769 $ 81,439 Credit facilities The Company’s primary credit facility is a $300.0 million syndicated multicurrency credit agreement with a group of lenders which matures in June 2018. The maximum amount available under this credit facility can be increased to $400.0 million at the Company’s option if the lenders agree and the Company satisfies certain conditions. Borrowings under this credit facility generally bear interest at a base rate or LIBOR rate plus a margin. Access to this credit facility is dependent on meeting certain financial and other covenants, but primarily depends on the Company’s consolidated leverage ratio calculation which cannot exceed 3.50 to 1. As of December 31, 2016 and 2015 , the Company’s consolidated leverage ratio was below 1.0 to 1, respectively, and the Company was also in compliance with all of the other covenants. At December 31, 2016 and 2015 , the Company had total credit facility borrowings of approximately $47.9 million and $62.9 million, primarily under this credit facility, at weighted average borrowing rates of 1.25% and 1.38%, respectively. Industrial development b onds The Company has two fixed rate, industrial development authority demand bonds, with $5.0 million due in 2018, bearing interest at a rate of 5.60%, and $10.0 million due in 2028, bearing interest at a rate of 5.26%. These bonds have similar covenants to the credit facilities noted above. Municipality-related loans As part of a past expansion project at the C ompany’s Middletown, Ohio facility, it agreed to a low interest rate $3.5 million loan with the Ohio Department of Development. Principal repayment on this loan began in September 2010 with its final maturity being in February 2021. The current interest rate of 2% will rise to 3% beginning March 2019 until final maturity. As of December 31, 2016 and 2015 , there was $1.5 million and $1.8 million, respectively, outstanding on this loan. With the 2015 acquisition of Verkol S.A. U. (“Verkol”), the Company assumed certain loans, issued by the local government, which are either interest-free or bear interest at a subsidized rate. These loans mature periodically, with the last maturity occurring in 2026. The Company recorded these loans at fair value based on market interest rates on the date of acquisition and continues to measure the loans at amortized cost, recognizing the implicit interest incurred. As of December 31, 2016 and 2015 , there was $2.0 and $2.3 million, respectively, outstanding for these loans. During the next five years, payments on the Company’s debt, including capital lease maturities, are due as follows: 2017 $ 707 2018 53,364 2019 645 2020 641 2021 341 At December 31, 2016 and 2015 , the amounts at which the Company’s debt is recorded are not materially different from their fair market value.

This change resulted in a decrease in the service and interest components for pension cost in the year ended December 31, 2016 compared to the year ended December 31, 2015. Historically, the Company estimated service and interest cost components utilizing a single weighted-average discount rate derived from a specific yield curve used to measure the benefit obligation at the beginning of the period. Under the spot-rate appr oach, service and interest cost components have been estimated based on the application of the spot rates on a given yield curve at each future year to each plan's projected cash flows to measure the benefit obligation at the beginning of the period. The Company made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows and the corresponding spot yield curve rates. This change has been accounted for as a change in accounting estimate and, accordingly, accounted for prospectively during 2016 . The long-term rates of return on assets were selected from within the reasonable range of rates determined by (a) historical real returns for the asset classes covered by the investment pol icy and (b) projections of inflation over the long-term period during which benefits are payable to plan participants. See Note 1 of Notes to Consolidated Financial Statements for further information.

The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy , where applicable : Cash and Cash Equivalents Cash and cash equivalents consist of cash and money market funds and are classifie d as Level 1 investments. Common Stock Common stock is valued based on quoted market prices on an exchange in an active market and is classified as Level 1 investments. Commingled Funds Investments in the U.S. pension plan and foreign pension plan commingl ed funds represent pooled institutional investments, including primarily collective investment trusts. The se commingled funds are not available o n an exchange or in an active market and these investments are valued using their NAV, which is generally base d on the underlying asset values of the pooled investments held in the trusts. In accordance with the accounting standard update adopted by the Company during 2016, these assets are no longer included in the fair value hierarchy. As of December 31, 2016 , the U.S. pension plan commingled funds include d approximately 61 percent of investments in equity securities and 39 percent of investments in fixed income securities. As of December 31, 2016, foreign pension plan commingled funds include d approximately 30 percent of investments in diversified equity securities, 60 percent of investments in fixed income securities , and 10 percent of other non-related investments , primarily real estate. Pooled Separate Accounts Investments in the U.S. pension plan pooled separate accounts consist of insurance annuity contracts and are valued based on the reported unit value at year end. Units of the pooled separate account are not traded on an exchange or in an active market and these investments are valued using t heir NAV. In accordance with the accounting standard update adopted by the Company during 2016, these assets are no longer included in the fair value hierarchy. Registered Investment Companies Investments in shares of registered investment companies in the U.S. pension plan as of December 31, 2015 which represent the net asset values of shares held by the Plan and were valued based on quoted market prices on an exchange in an active market and classified as Level 1 investments. Fixed Income Corporate Sec urities Investments in corporate fixed income securities in the U.S. pension plan as of December 31, 2015 were valued using third party pricing services which were based on a combination of quoted market prices on an exchange in an active market as well as proprietary pricing models and inputs using observable market data and were classified as Level 2 investments. Fixed Income U.S. and Foreign Government Securitie s Investments in U.S. and foreign government fixed income securities in the U.S. pension plan as of December 31, 2015 were valued using third party pricing services which are based on a combination of quoted market prices on an exchange in an active market as well as proprietary pricing models and inputs using observable market data and were classified as Level 2 investments. Insurance Contract Investments in the foreign pension plan insurance contract are valued at the highest value available for the Com pany at year end, either the reported cash surrender value of the contract or the vested benefit obligation. Both the cash surrender value and the vested benefit obligation are determined based on unobservable inputs, which are contractually or actuariall y determined, regarding returns, fees, the present value of the future cash flows of the contract and benefit obligations. The contract is classified as a Level 3 investment. Diversified Equity Securities - Registered Investment Companies Investments in t he foreign pension plan diversified equity securities of registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available o n an exchange or in an activ e market; however, the fair value is determined based on the underlying inve stments in the fund as traded on an exchange in an active market and are classified as Level 2 investments. Fixed Income – Foreign Registered Investment Companies Investments in th e foreign pension plan fixed income securities of foreign registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available o n an exchange or in an acti ve market; however, the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market and are classified as Level 2 investments. Real Estate The foreign pension plan’s investment in real estate consists of an investment in a property fund. The fund’s underlying investments consist of real property, which are valued using unobservable inputs. The property fund is classified as a Level 3 investment As of December 31, 2016 and 2015 , the U.S. and foreign plans’ investments measured at fair value on a recurring basis were as follows: Fair Value Measurements at December 31, 2016 Total Using Fair Value Hierarchy U.S. Pension Assets Fair Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 302 $ 302 $ — $ — Small capitalization common stock 1,279 1,279 — — Subtotal U.S. pension plan assets in fair value hierarchy $ 1,581 $ 1,581 $ — $ — Commingled funds measured at NAV 46,185 Pooled separate accounts measured at NAV 1,431 Total U.S. pension plan assets $ 49,197 Foreign Pension Assets Cash and cash equivalents $ 130 $ 130 $ — $ — Insurance contract 72,778 — — 72,778 Diversified equity securities - registered investment companies 7,308 — 7,308 — Fixed income - foreign registered investment companies 2,753 — 2,753 — Real estate - registered investment companies 2,041 — — 2,041 Sub-total of foreign pension assets in fair value hierarchy $ 85,010 $ 130 $ 10,061 $ 74,819 Commingled funds measured at NAV 1,834 Total foreign pension assets $ 86,844 Total pension assets in fair value hierarchy $ 86,591 $ 1,711 $ 10,061 $ 74,819 Total pension assets measured at NAV 49,450 Total pension assets $ 136,041 Fair Value Measurements at December 31, 2015 Total Using Fair Value Hierarchy U.S. Pension Assets Fair Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 753 $ 753 $ — $ — Large capitalization common stock 13,346 13,346 — — Large capitalization registered investment companies 6,363 6,363 — — Small capitalization common stock 773 773 — — Small capitalization registered investment companies 2,333 2,333 — — International developed and emerging markets registered investment companies 5,166 5,166 — — International developed and emerging markets common stock 2,519 2,519 — — Fixed income corporate securities 9,601 — 9,601 — Fixed income registered investment companies 4,147 4,147 — — Fixed income U.S. and foreign government securities 308 — 308 — Subtotal U.S. pension plan assets in fair value hierarchy $ 45,309 $ 35,400 $ 9,909 $ — Pooled separate accounts measured at NAV 1,392 Total U.S. pension plan assets $ 46,701 Foreign Pension Assets Cash and cash equivalents $ 7 $ 7 $ — $ — Insurance contract 62,409 — — 62,409 Diversified equity securities - registered investment companies 7,180 — 7,180 — Fixed income - foreign registered investment companies 2,290 — 2,290 — Real estate - registered investment companies 2,388 — — 2,388 Subtotal foreign pension assets in fair value hierarchy $ 74,274 $ 7 $ 9,470 $ 64,797 Commingled funds measured at NAV 1,882 Total foreign pension plan assets $ 76,156 Total pension assets in fair value hierarchy $ 119,583 $ 35,407 $ 19,379 $ 64,797 Total pension assets measured at NAV 3,274 Total pension assets $ 122,857 Certain investments that are measured at fair value using the NAV per share (or its equivalent) have not bee n classified in the fair value hierarchy . During 2016, the Company adopted the guidance in the accounting standard update issued in May, 2015 which removed the requirement to categorize within the fair value hierarchy all such investments . Adoption of this guidance was done on a retrospective basis, which required reclassifications to the fair value tables for the year ended December 31, 2015. The fair value amounts presented for these investments in the preceding tables are intended to permit reconciliation of the fair value hierarchies to t he line items presented in the statements of net assets available for benefits. Changes in the fair value of the foreign plans’ Level 3 investments during the years ended December 31, 2016 and 2015 were as follows: Insurance Real Estate Contract Fund Total Balance at December 31, 2014 $ 72,417 $ 478 $ 72,895 Purchases 953 1,937 2,890 Settlements (1,239) — (1,239) Unrealized (losses) gains (2,402) 60 (2,342) Currency translation adjustment (7,320) (87) (7,407) Balance at December 31, 2015 62,409 2,388 64,797 Purchases 2,584 — 2,584 Settlements (1,350) — (1,350) Unrealized gains 12,005 56 12,061 Currency translation adjustment (2,870) (403) (3,273) Balance at December 31, 2016 $ 72,778 $ 2,041 $ 74,819 U.S. pension assets include Company common stock in the amounts of $1.3 million ( 3% of total U.S. plan assets) and $0.8 million ( 2% of total U.S. plan assets) at December 31, 2016 and 2015 , respectively. During 2013, it was discovered that the Company’s subsidiary in the U.K. did not appropriately amend a trust for a lega cy change in its pension scheme as it related to a past retirement age equalization law. Given the lack of an official deed to the pen sion trust, the effec tive date of the change to the s ubsidiary’s pension scheme differed from the Company’s historical beliefs, but the extent of the potential exposure was not estimable. In the first quarter of 2014, the Company recorded costs of $ 0. 9 mi llion , or $0.05 per diluted share, related to prior service cost and interest cost, to appropriately reflect the past plan amendment related to the retirement age equalization law. Cash Flows Contributions The Company expects to make minimum cash contributions of $7.8 million to its pension plans ( $4.6 million Domestic and $3.2 million Foreign) and $0.5 million to its other postretirement benefit plan in 2017 . Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Other Post- Pension Benefits Retirement Foreign Domestic Total Benefits 2017 $ 1,780 $ 4,929 $ 6,709 $ 451 2018 1,946 4,642 6,588 444 2019 2,094 4,605 6,699 432 2020 2,311 4,354 6,665 407 2021 2,922 4,346 7,268 385 2022 to 2026 16,581 23,445 40,026 1,611 The Company maintains a plan under which supplemental retirement benefits are provided to certain officers. Benefits payable under the plan are based on a combination of years of service and existing postretirement benefits. Included in total pension costs are charges of $0.9 million , $0.9 million and $0.8 million in 2016 , 2015 and 2014 , respectively, representing the annual accrued benefits under this plan. Defined Contribution Plan The Company has a 401 (k) plan with an employer match covering a majority of its domestic employees. The plan allows for and the Company has paid a nonelective contribution on behalf of participants who have completed one year of service equal to 3% of the eligible participant s’ compensation in the form of Company common stock. Total Company contributions were $2.7 million , $2.6 million and $2.5 million for 2016 , 2015 and 2014 , respectively.

Equity [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	In May 2015, the Company’s Board of Directors authorized a share repurchase program for the repurchase of up to $100.0 million of Quaker Chemical Corporation common stock (the “2015 Share Repurchase Program”). The 2015 Share Repurchase Program has no expiration date. The 2015 Share Repurchase Program provides a framework of conditions under which management can repurchase shares of the Company’s common stock. The Company currently intend s to repurchase shares to at least offset the dilutive impact of shares issued each year as part of its employee benefit and share based compensation plans, and could repurchase more if the Company considers the share price to be at a level that offers an advantageous return for its shareholders. The purchases may be made in the open market or in private and negotiated transactions and will be in accordance with applicable laws, rules and regulations. In connection with the 2015 Share Repurchase Program, the remaining unutilized 1995 and 2005 Board of Directors authorized share repurchase programs were terminated. In connection with the 2015 Share Repurchase Program, the Company acquired 83,879 shares of common stock for $ 5.9 million, d uring the year ended December 31, 2016 , and 87,386 shares of common stock for $ 7.3 million during the year ended December 31, 2015 . The Company has elected not to hold treasury shares and therefore has retired the share s as they are repurchased. It is the Company’s accounting policy to record the excess paid over par value as a reduction in retained earnings for all shares repurchased. The Company has 30,000,000 shares of common stock authorized with a par value of $1, and 13,277,832 and 13,288,113 shares issued as of December 31, 2016 and 2015 , respectively. The change in shares issued and outstanding during 2016 was primarily related to 83,879 shares repurchased in connection with t he 2015 Share Repurchase Program offset by 55,982 shares issued for equity-based compensation plans, 6,130 shares issued for the ESPP and 11,486 shares issued for the exercise of stock options and other employee and director-rel ated share activity. Holders of record of the Company’s common stock for a period of less than 36 consecutive calendar months or less are entitled to one vote per share of common stock. Holders of record of the Company’s common stock for a period great er than 36 consecutive calendar months are entitled to 10 votes per share of common stock. The Company is authorized to issue 10,000,000 shares of preferred stock with $1 par value, subject to approval by the Board of Directors. The Board of Directors may designate one or more series of preferred stock and the number of shares, rights, preferences, and limitations of each series. As of December 31, 2016 , no preferred stock had been issued.

This includes a post-closing adjustment of 1.3 million EUR, or approximately $1.4 million that was accrued as of December 31, 2015 and paid during the first quarter of 2016. The purchase included cash acquired of 14.1 million EUR, or approximately $15.4 million, and assu med long-term debt of 2.2 million EUR, or approximately $2.4 million. During the first six months of 2016, the Company identified and recorded certain adjustments to the allocation of the purchase price for the Verkol acquisition. These adjustments were the result of the Company assessing additional information related to assets acquired during the one-year measurement period following the acquisition. As of June 30, 2016, the allocation of the purchase price for the Verkol acquisition was finalized. T he following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed for the Verkol acquisition: Verkol Acquisition Current assets (includes cash acquired) $ 31,151 Property, plant and equipment 7,941 Intangibles Customer lists and rights to sell 6,146 Trademarks, formulations and product technology 5,378 Other intangibles 219 Goodwill 5,051 Other long-term assets 158 Total assets purchased 56,044 Current liabilities (6,720) Long-term debt (2,400) Other long-term liabilities (5,531) Total liabilities assumed (14,651) Gross cash paid for acquisition $ 41,393 Less: cash acquired 15,423 Net cash paid for acquisition $ 25,970 In December 2014, the Company acquired a business that is principally concerned with safety fluid applications for mining sites in its Asia/Pacific reportable operating segment for net consideration of approximately 2.9 million AUD, or approximately $2.4 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 22 – Commitments and Contingencies In 1992, the Company identified certain soil and groundwater contamination at AC Products, Inc. (“ACP”), a wholly owned subsidiary. In voluntary coordination with the Santa Ana California Regional Water Quality Board (“SACRWQB”), ACP has been remediating the contamination, the principal contaminant of which is perchloroethylene (“PERC”). In 2004, the Orange County Water District (“OCWD”) filed a civil complaint against ACP and other parties seeking to recover compensatory and other damages related to the investigation and remediation of the contamination in the groundwater. Pursuant to a settlement agreement with OCWD, ACP agreed, among other things, to operate the two groundwater treatment systems to hydraulically contain groundwater contamination emanat ing from ACP’s site until the concentrations of PERC released by ACP fell below the current Federal maximum contaminant level for four consecutive quarterly sampling events. In 2014, ACP ceased operation at one of its two groundwater treatment systems, as it had met the above condition for closure. As of December 31, 2016, ACP believes it is close to meeting the conditions for closure of the remaining groundwater treatment system, but continues to operate this system while in discussions with the relevant authorities . As of December 31, 2016 , the Company believes that the range of potential-known liabilities associated with the balance of ACP water remediation program is approximately $0.1 million to $1.0 million. The low and high ends o f the range are based on the length of operation of the treatment system as required by the conditions noted above, as determined by groundwater modeling . Costs of operation include the operation and maintenance of the extraction well, groundwater monitor ing and program management. The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated with other environmental problems of which it is aware. Approximately $0.2 million and $0.3 million was accrued at December 31, 2016 and 2015 , respectively, to provide for such anticipated future environmental assessments and remediation costs. An inactive subsidiary of t he Company that was acquired in 1978 sold certain products containing asbestos, primarily on an installed basis, and is among the defendants in numerous lawsuits alleging injury due to exposure to asbestos. The subsidiary discontinued operations in 1991 a nd has no remaining assets other than proceeds received from insurance settlements. To date, the overwhelming majority of these claims have been disposed of without payment and there have been no adverse judgments against the subsidiary. Based on a conti nued analysis of the existing and anticipated future claims against this subsidiary, it is currently projected that the subsidiary’s total liability over the next 50 years for these claims is approximately $2.2 million (excluding costs of defense). Alth ough the Company has also been named as a defendant in certain of these cases, no claims have been actively pursued against the Company, and the Company has not contributed to the defense or settlement of any of these cases pursued against the subsidiary. These cases were handled by the subsidiary’s primary and excess insurers who had agreed in 1997 to pay all defense costs and be responsible for all damages assessed against the subsidiary arising out of existing and future asbestos claims up to the aggreg ate limits of their policies. A significant portion of this primary insurance coverage was provided by an insurer that is insolvent, and the other primary insurers asserted that the aggregate limits of their policies have been exhausted. The subsidiary c hallenged the applicability of these limits to the claims being brought against the subsidiary. In response, two of the three carriers entered into separate settlement and release agreements with the subsidiary in 2005 and 2007 for $15.0 million and $20.0 million, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. In 2007, the subsidiary and the remaining primary insurance carrier ente red into a Claim Handling and Funding Agreement, under which the carrier is paying 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims. The agreement continues until terminated and can only be terminated by either party by providing a minimum of two years prior written notice. As of December 31, 2016 , no notice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may c hoose to again pursue its claim against this insurer regarding the application of the policy limits. The Company believes that, if the coverage issues under the primary policies with the remaining carrier are resolved adversely to the subsidiary and all s ettlement proceeds were used, the subsidiary may have limited additional coverage from a state guarantee fund established following the insolvency of one of the subsidiary’s primary insurers. Nevertheless, liabilities in respect of claims may exceed the a ssets and coverage available to the subsidiary. If the subsidiary’s assets and insurance coverage were to be exhausted, claimants of the subsidiary may actively pursue claims against the Company because of the parent-subsidiary relationship. The Company d oes not believe that such claims would have merit or that the Company would be held to have liability for any unsatisfied obligations of the subsidiary as a result of such claims. After evaluating the nature of the claims filed against the subsidiary and the small number of such claims that have resulted in any payment, the potential availability of additional insurance coverage at the subsidiary level, the additional availability of the Company’s own insurance and the Company’s strong defenses to claims t hat it should be held responsible for the subsidiary’s obligations because of the parent-subsidiary relationship, the Company believes it is not probable that the Company will incur losses. The Company has been successful to date having any claims naming it dismissed during initial proceedings. Since the Company may be in this stage of litigation for some time, it is not possible to estimate additional losses or range of loss, if any. As initially disclosed in 2010, one of the Company’s subsidiaries may h ave paid certain value-added-taxes (“VAT”) incorrectly and, in certain cases, may not have collected sufficient VAT from certain customers. The VAT rules and regulations at issue are complex, vary among the jurisdictions and can be contradictory, in parti cular as to how they relate to the subsidiary’s products and to sales between jurisdictions. Since its inception, the subsidiary had been consistent in its VAT collection and remittance practices and had never been contacted by any tax authority relative to VAT. The subsidiary later determined that for certain products, a portion of the VAT was incorrectly paid and that the total VAT due exceeded the amount originally collected and remitted by the subsidiary. In response, the subsidiary modified its VAT invoicing and payment procedures to eliminate or mitigate future exposure. In 2010, three jurisdictions contacted the subsidiary and, in 2013, an additional jurisdiction issued an assessment against the subsidiary for certain tax years. As of December 3 1, 2016, the Company had no remaining accrual for this or any other related tax assessment, as the subsidiary had previously participated in an amnesty program or had entered into a settlement arrangement with each jurisdiction. Also, the Company believes there are no potentially impacted jurisdictions remaining due to the expiration of the applicable statutes of limitation on past assessments as of December 31, 2016 . The Company is party to other litigation which management currently believes will not hav e a material adverse effect on the Company’s results of operations, cash flows or financial condition. The Company leases certain manufacturing and office facilities and equipment under non-cancelable operating leases with various terms from 1 to 15 years expiring in 20 31 . Rent expense for the years ended December 31, 2016 , 2015 and 2014 was $5.6 million, $5.9 million, and $5.8 million, respectively. 2017 $ 5,279 2018 2,967 2019 2,613 2020 2,225 2021 1,962 2022 and beyond 9,758

Significant Accounting Polici32

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy [Policy Text Block]	All majority-owned subsidiaries are included in the Company’s consolidated financial statements, with appropriate elimination of intercompany balances and transactions.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	The Financial Accounting Standards Board’s (“FASB’s”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabil ities and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance.
Equity and Cost Method Investments, Policy [Policy Text Block]	Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company’s share of net income or losses in these investments in associated companies is included in the C onsolidated Statement s of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and associated comp anies are translated into U.S. d ollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resultin g from this process are recorded directly in equity as accumulated other comprehensive (loss) income (“AOCI”) and will be included as income or expense only upon sale or liquidation of the underlying investment. Generally, all of the Company’s non-U.S. su bsidiaries use their local currency as their functional currency.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents: The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company consid ers all highly liquid investments with original maturities of three months or less to be cash equivalents.
Inventory, Policy [Policy Text Block]	Inventories: Inventories are valued at the lower of cost or net realizab le val ue, and are valued using the first-in, first-out (“FIFO”) method.
Property, Plant and Equipment, Policy [Policy Text Block]	Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line me thod on an individual asset basis over the following estimated useful lives: building s and improvements , 10 to 45 years; and machinery an d equipment, 1 to 15 years. The carrying value s of long-lived assets are evaluate d whenever changes in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future cash fl ows. Upon sale or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in the Consolidated Statements of I nco me. Expenditures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenan ce are expensed when incurred.
Internal Use Software, Policy [Policy Text Block]	Capitalized software: The Company capitalizes certain costs in connection with developing or obtaining software for internal use , depending on the associated project . These costs are amortized over a period of 3 to 5 year s once the assets are ready for their intended use.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets a nd indefinite-lived intangible assets at fair value at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering ev ents indicate potential impairment. Definite-lived intangible assets are amortized over their estimated useful lives, gen erally for periods ranging from 4 to 20 years. The Company continually evaluates the reasonableness of the useful l ives of these assets, consistent with the discussion of long-lived assets, above.
Revenue Recognition Accounting Policy, Gross and Net Revenue Disclosure [Policy Text Block]	Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. For the Company, t his generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fees and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is r easonably assured. As part of the Company’s chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods.
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Accounts receivable and allowance for doubtful accounts: Trade accounts receivable subject the Company to credit risk. Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses with its existing accounts receivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount outstanding at the bankruptcy filing date. However, initially establishing a reserve and the amount thereto is dependent on the Company’s evaluation of likely proceeds to be received from the bankruptcy process, which could result in the Company recognizing minimal or no reserve at the date of bankruptcy. Large and/or financially distress ed customers are generally reserved for on a specific review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account b alances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers.
Research and Development Expense, Policy [Policy Text Block]	Research and development costs: Research and development costs are expensed as incurred and are included in selling, general and administrative expenses (“SG&A”) .
Environmental Costs, Policy [Policy Text Block]	Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liabi lity has been incurred and the amount of the liability can be reasonably estimated. If there is a range of estimated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capac ity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or preven t contamination in the future.
Asset Retirement Obligations, Policy [Policy Text Block]	Asset retirement obligations: The Company follows the FASB’s guidance regarding asset retirement obligations, which addresses the accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB’ s guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within t he control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension and other postretirement benefits: The Company maintains various noncontributory retirement pl ans, the largest of which is in the U.S., covering a portion of its employees in the U.S. and certain other countries. The plans of the Company’s subsidiaries in t he Netherlands, the United Kingdom (“U.K.”) , Mexico and Sweden are subject to the provisions of FASB’s guidance regarding employers’ accounting for defined benefit pension plans. The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments’ plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost. The Company’s U.S. pension plan year ends on November 30 and th e measurement date is December 31. The measurement date for the Company’s other postretirement benefits plan is December 31. The Company’s global pension investment polic ies are designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. The Company’s investment horizon is gen erally long term, and, accordingly, the target asset allocations encompass a long- term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in intermediate plan distributions, and the total return portfolio is expecte d to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company’s investment guidelines prohibi t use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specifically addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging. The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships . The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitored with an overall expectation that plan assets will meet or exceed bench mark performance over rolling five-year periods. The Company’s pension committee, as authorized by the Company’s Board of Directors, has discretion to manage the assets within established asset allocation ranges approved by senior management of the Compan y.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive income (loss): The Company presents other comprehensi ve income (loss) in its Statement s of Comprehensive Income. The Company follows the FASB’s guidance regarding the disclosure of reclas sifications from AOCI which requires the disclosure of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by such reclassifications.
Income Tax, Policy [Policy Text Block]	Income taxes and uncertain tax positions: The provision for income taxes is determined using the asse t and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.
Income Tax Uncertainties, Policy [Policy Text Block]	The FASB’s guidance regarding accounting for uncertainty in inco me taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the ben efits of tax positions will be more likely than not sustained upon audit based upon the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the ben efit in the financial statements. Additionally, the Company monitors and adjusts for derecognition, classification, and penalties and interest in interim periods, with appropriate disclosure and transition thereto . A lso , the amount of interest expense an d income related to uncertain tax positions is computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company’s continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Finally, when applicable, t he Company net s its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would apply if the uncertain tax position were settled for the presumed amount at the balance sheet date.
Derivatives, Policy [Policy Text Block]	Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivat ive instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. When used, the Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hedges, the effective portion of any hedge would be reported in AOCI until it was cleared to earnings durin g the same period in which the hedged item affected earnings.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value measurements: The Company utilizes the FASB’s guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into thr ee broad levels. See Notes 17 and 21 of Notes to Consolidated Financial Statements. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-based compensation: The Company applies the FASB’s guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Restricted stock awards and r estricted s tock u nits (“RSU”) issued under the LTIP program are generally subject to time vesting over a one to five-year period. In ad dition, as part of the Company’s Global Annu al Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated.
Earnings Per Share, Policy [Policy Text Block]	Earnings per share: The Company follows the FASB’s guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method.
Segment Reporting, Policy [Policy Text Block]	Segments: The Company’s reporting segments are the same as the Company’s operating segments. The Company’s reportable operating segments evidence the structure of the Company’s internal organization, the method by which the Company’s resources are allocated and the manner by which the Company assesse s its performance.
Business Combinations Policy [Policy Text Block]	Business combinations: The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets and assumed liabilities at their respective acquisition date estimated fair values. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. The determination of the estimated fair value of assets acquired and liabi lities assumed requires significant estimates and assumptions. Based on the assessment of additional information during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the estimated fair value of assets acquired and liabilities assumed.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring activities: Restructuring programs consist of employee severance, rationalization of manufacturing or other facilities and other related items. To account for such programs , the Company applies FASB’s guidance regarding exit or disposal cost obligations. This guidance requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, is estimable, and payment is probable.
Reclassification, Policy [Policy Text Block]	Reclassifications : Certain information has been reclassified to conform to the current year presentation.
Use of Estimates, Policy [Policy Text Block]	Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilitie s and disclosure of contingencies at the date of the financial statements and the reported amounts of net sales and expens es during the reporting period. Actual results c ould differ from such estimates.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Prior Period Reclassifications	The FASB issued an accounting standard update in November 2015 regarding the classification of deferred taxes on the balance sheet. The update requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The update does not change the existing requirement that only permits offsetting within a jurisdiction. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2016, and may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. Early adoption is permitted. During the fourth quarter of 2016, the Company early adopted the guidance of this accounting standard update and applied the guidance in this accounting standard update retrospectively. Including the first quarter of 2016 revision noted in Note 1 of Notes to Consolidated Financial Statements, adoption of the accounting standard update resulted in a reclassification to the Company’s Consolidated Balance Sheet as of December 31, 2015, reducing current deferred tax assets by $7.8 million, current deferred tax liabilities by less than $0.1 million, and non-current deferred tax liabilities by $4.7 million, and increasing non-current deferred tax assets by $3.0 million.

Intangible Assets Reclassified as Held for Sale			$ 300
Restructuring And Related Cost Description		The 2015 Program included provisions for the reduction of total headcount by approximately 65 employees globally. As a result of this program, the Company recognized a $6.8 million, or $0.36 per diluted share, restructuring charge in the fourth quarter of 2015. Employee separation costs varied depending on local regulations within certain foreign countries and included severance and other benefits. The Company substantially completed all of the initiatives under the 2015 Program in 2016 and settlement of these charges occurred primarily in 2016 as well. During the fourth quarter of 2016, the Company recognized a restructuring credit of $0.4 million, or $0.02 per diluted share, in connection with the 2015 Program, due to customary and routine adjustments to initial estimates for employee separation costs, as well as the reversal of certain accrued employee separation costs as a result of the change in available-for-sale technology, noted above. At this time, the Company does not expect to incur material additional restructuring charges or credits under the 2015 Program
Disposal Group Including Discontinued Operation Changes To Plan Of Sale	During the fourth quarter of 2016, the Company made a decision to no longer market or make available-for-sale this technology, which resulted in $0.3 million of other current assets being reclassified back to intangible assets as of December 31, 2016.

Loss Contingency, Settlement Agreement, Terms	In response, two of the three carriers entered into separate settlement and release agreements with the subsidiary in 2005 and 2007 for $15.0 million and $20.0 million, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. In 2007, the subsidiary and the remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier is paying 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims. The agreement continues until terminated and can only be terminated by either party by providing a minimum of two years prior written notice. As of December 31, 2016, no notice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application of the policy limits.
