Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 – Condensed Financial Information The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial reporting and the United States Securi ties and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the o pinion of management, the financial statements reflect all adjustments (consisting only of normal recurring adjustments, except certain material adjustments, as discussed below) which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with t he Company’s Annual Report filed on Form 10-K for the year ended December 31, 2014 . In 2003, the Venezuelan government suspended the free exchange of Bolivar Fuerte (“ BsF ”) for foreign currency and im plemented certain foreign exchange controls that served to centralize the purchase and sale of foreign currency within the country. 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 (approximately 12 BsF per U.S. Dollar) and the SICAD II (approximately 52 BsF per U.S. Dollar). In the first quarter of 2015, the Company understood that the Venezuelan government announced changes to its exchange co n trols. The Company understood that there continued to be three exchange mechanisms in Venezuela; however, they now consist ed of the CADIVI, a combined SICAD I and SICAD II auction mechanism (the “SICAD”) and a newly created, marginal currency system (the “SIMADI”). The CADIVI exchange largel y remained the same, except that the government further restricted what products qualify and can, therefore, legally be imported or traded under this exchange. The government has yet to fully disclose who can access o r trade on the newly for med combined SICAD market and minimal related auctions have occurred since late 2014. Finally, the newly created SIMADI is legally available to all parties, however, at significantly higher exchange rates than the CADIVI or SICAD. As of June 30, 2015 , the published rate for the SIMADI is approximately 197 BsF per U.S. Dollar. The Company has a Venezuelan equity affiliate, Kelko Quaker Chemical, S.A. (“ Kelko Venezuela”). Venezuela’s economy has been considered hyper inflationary under U.S. GAAP since 2010, at which time Kelko Venezuela’s functional currency was changed to the U.S. Dollar. Accordingly, all gains and losses resulting from the remeasurement of Kelko Venezuela’s monetary assets and liabilities to the CADIVI or other published exchange rates are required to be recorded directly to the Condensed Consolidated Statement of Income. As of December 31, 2014, 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. In light of the first quarte r 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 Venezuela, and the impact on the Company’s equity investment and other related assets. During the first quarter of 2015, the Company determined that the CADIVI was no longer available to Kelko Venezuela for import transactions and the government has yet to fully disclose who can access or trade o n the newly formed combined SICAD mechanism and minimal related auctions have occurred to date. As a result, the Company revalued 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 approximately $2,806 , or $0.21 per diluted share, recorde d in the first quarter of 2015. Comparatively, during the second quarter of 2014, the Company recorded a charge of $321, or $0.02 per diluted share, related to the conversion of certain Venezuelan Bolivar Fuerte to U.S. Dollars on the historical SICAD II exchange. As of June 30, 2015 , the Company’s equity investment in Kelko Venezuela was $143 , which continues to be valued at the SIMADI exchange rate. 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 the principal, revenue is recognized on a gross reporting basis at the selling price negotiated with customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenues, at the amount of the administrative fee earned by the Co mpany for ordering the goods. Third-party products transferred under arrangements resulting in net reporting totaled $12,188 and $24,053 for the three and six months ended June 30, 2015 , respectively. Comparatively, t hird-party products transferred u nder arrangements resulting in net reporting totaled $10,926 and $21,499 for th e three and six months ended June 30, 2014 , respectively.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 2 – Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standard update in May 2015 regarding the required disclosures for entities that elect to measure the fair value of certain investments using the net asset value 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 , also , limit s the requirement to make certain other disclosures , for all such investments. The amendments in this update are effective for fiscal y ears beginning after December 15 , 2015, and interim periods within those fiscal years, and should be applied on a retrosp ective basis for the periods presented. Early adoption is permitted. The Company is currently evaluatin g the effects of this guidance, but does not expect a material impact. The FASB issued an accounting standard update in April 2015 regarding the presen tation 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 separate asset. The amendments in this update are effective for an nual and interim periods beginning after December 15, 2015 and should be applied on a retrospective basis for the periods presented. Early adoption is permitted. Also, in June 2015, the SEC staff announced that the guidance within this accounting standar d update was not applicable to revolving debt arrangements or credit facilities. The Company is currently evaluating the effects of this guidance, and the SEC’s recent announcement, but does not expect a material impact. The FASB issued an accounting stan dard 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 contracts with customers, which will be c ommon to both U.S. GAAP and International Financial Reporting Standards. The guidance was effective for annual and interim periods beginning after December 15, 2016, which allowed for full retrospective adoption of prior period data or a modified retrospe ctive adoption. Early adoption was not permitted. In July 2015, the FASB issued an update to delay the effective date of the new revenue standard by one year, or, in other words, to be effective 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. The Company is currently evaluating the effects of this guidance.

During the first quarter of 2015 , the Company granted stock options under its LTIP plan that are subject only to time vesting over a three-year period. For the purposes of determining the fair value of stock option awards, the Company uses the Black-Scholes option pricing model and the assumptions set forth in the table below: 2015 Number of options granted 38,698 Dividend Yield 1.55 % Expected Volatility 36.32 % Risk-free interest rate 1.22 % Expected term (years) 4.0 Approximately $74 and $101 of expense was recorded on these options during the three and six months ended June 30, 2015 , respectively . The fair value of these awards is amortized on a straight-line basis over the vesting period of the awards. Activity of nonvested shares granted under the Company’s LTIP plan is shown below: Weighted Average Grant Number of Date Fair Value Shares (per share) Nonvested awards, December 31, 2014 124,450 $ 61.80 Granted 27,266 $ 86.39 Vested (32,931) $ 46.40 Forfeited (3,421) $ 62.65 Nonvested awards, June 30, 2015 115,364 $ 71.99 The fair value of the nonvested stock is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of June 30, 2015 , unrecognized compensation expense related to these awards was $4,941 to be recognized over a weighted average remaining period of 2.08 years. Activity of nonvested restricted stock units granted under the Company’s LTIP plan is shown below: Weighted Average Grant Number of Date Fair Value Units (per unit) Nonvested awards, December 31, 2014 7,158 $ 61.03 Granted 1,450 $ 87.30 Vested (2,434) $ 43.45 Nonvested awards, June 30, 2015 6,174 $ 74.14 The fair value of the nonvested restricted stock units is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of June 30, 2015 , unrecognized compensation expense related to these awards was $236 to be recognized over a weighted average remaining period of 1.97 years. 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 account 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 % disc ount 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.

Given the lack of an official deed to the pension trust, the effective date of the change to the Subsidiary’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 r ecorded costs of $902, 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. Employer Contributions The Company previously disclosed in its financial statements for the year ended December 31, 2014 , that it expected to make mini mum cash contributions of $4,176 to its pension plans and $568 to its other postretirement benefit plan in 2015 .

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 7 – Income Taxes and Uncertain Income Tax Positions The Company’s first six months of 2015 effective tax rate was 28.8% , compared to the first six months of 2014 effective tax rate of 32.5% . The primary contributors to the difference in the effective tax rate from the prior year were lower changes in reserves related to uncertain tax positions and the recognition of certain one time items that increased the first six months of 2014’s effective tax rate. As of June 30, 2015 , the Company’s cumulative liability for gross unrecognized tax benefits was $11,339 . At December 31, 2014 , the Company’s cumulative liability for gross unrecognized tax benefits was $11,845 . The Company continues to recognize interest and penalties associated with uncertain tax positions as a component of taxes on income before equity in net income of associated companies in its Condensed Consolidated Statements of Income. The Comp any recognized $57 an d ($161) for interest and $114 and $187 for penalties on its Condensed Consolidated Statement of Income for the three and six months ended June 30, 2015 , respectively, and recognized $154 and ($58) for inte rest and $108 and $98 for penalties on its Condensed Consolidated Statement of Income during the three and six months ended June 30, 2014 , respectively . As of June 30, 2015 , the Company had accrued $1,575 for cumulative interest and $1,897 for cumulative penalties, compared to $1,868 for cumulative interest and $1,845 for cumulative penalties accrued at December 31, 2014 . During the three months ended June 30, 2015 and 2014 , re spectively, there were no expirations of statutes of limitations for uncertain tax positions. During the six months ended June 30, 2015 , the Company recognized a decrease of approximately $741 in its cumulative liability for gross unreco gnized tax benefits due to the expiration of the applicable statutes of limitations for certain tax years. During the six months ended June 30, 2014 , the Company recognized a decrease of approximately $1,075 in its cumulative liability for gross unrecognized tax benefits due to the expiration of the applicable statutes of limitations for certain tax years. The Company estimates that during the year ending December 31, 2015 it will reduce its cumulative liability for gross unrecogn ized tax benefits by approximately $1,800 to $1,900 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 an y increase in liability 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, 2015 . 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 N etherlands and the United Kingdom from 2009, Spain and China from 2010, the United States from 2011, and various domestic state tax jurisdictions from 1993. During 2012, the Italian tax authorities initiated a transfer pricing audit of the Company’s Italia n subsidiary , Quaker Italia S.r.l ., relating to the tax years 2007, 2008, 2009 and 2010. The Italian tax authorities had previously made assessments for the tax years 2007, 2008 and 2009. In the second quarter of 2015, the Italian tax authorities made a formal assessment for the tax year 2010. The Company is pursuing its administrative remedies to appeal these assessments. There have been no significant developments during the second quarter of 2015 related to these tax assessments. With respect to the Italian income tax assessment for 2007, the Company has established a reserve for uncertain tax positions and does not expect a material difference from this reserve as of June 30, 2 015. Related to the assessments for 2008 , 2009 and 2010 , the Company and outside counsel believe it should prevail on the merits of each case. Therefore, the Company does not believe it has exposure warranting an uncertain tax position reserve as of June 30, 2015. During the second quarter of 2015, the Italian tax authorities conducted an audit of the Company’s Italian subsidiary, Quaker Chemical S.r.l . (formerly NP Coil Dexter Industries, S.r.l .), relating to the tax years 2010, 2011, 2012 and 2013, an d proposed audit adjustments for those years. As of June 30, 2015 , the Company established a reserve for uncertain tax positions related to these proposed audit adjustments.

The Company also assumed an additional 300 Australian Dollars, or approximately $248, hold-back of consideration. This acquisition provides a strategic opportunity for Quaker in the core Australian minin g market. The Company allocated the purchase price to $1,802 of intangible assets, comprised of trademarks and formulations, to be amortized over 15 years; a non-competition agreement, to be amortized over 5 years; and customer relationships, to be amorti zed over 15 years. In addition, the Company has recorded $1,178 of goodwill, related to expected value outside its other acquired assets, all of which will not be tax deductible. In November 2014, the Company acquired Binol AB (“ Binol ”), a leading bio-lub ricants producer primarily serving the Nordic region for its EMEA reportable operating segment for approximately 136,500 SEK, or approximately $18,536, which is net of 4,400 SEK, or approximately $528, received by the Company as part of a post-closing adju stment in the first quarter of 2015. The post-closing adjustment recorded in the first quarter of 2015 adjusted the acquisition’s goodwill. This acquisition provides a strategic opportunity for Quaker to leverage Binol's environmentally friendly technolo gy and customer-aligned products, including neat oil technology for metalworking applications and biodegradable hydraulic oils, across the Company’s global footprint. The Company allocated the purchase price to $11,805 of intangible assets, comprised of t rademarks and formulations, to be amortized over 15 years; a non-competition agreement, to be amortized over 5 years; and customer relationships, to be amortized over 14 years. In addition, the Company has recorded $5,726 of goodwill, net of the $528 post -closing adjustment mentioned above, related to expected value outside its other acquired assets, all of which will not be tax deductible. In August 2014, the Company acquired ECLI Products, LLC (“ECLI”), a specialty grease manufacturer for its North Amer ican reportable operating segment for approximately $53,145, including certain post-closing adjustments. ECLI specializes in greases for OEM first-fill customers across several industry sectors, including automotive, industrial, aerospace/military, elect ronics, office automation and natural resources. This acquisition complements Quaker’s entry into the specialty grease market that began in 2010, and, also, provides an opportunity to leverage Quaker's global footprint with its current market expertise. The Company allocated the purchase price to $31,050 of intangible assets, comprised of trademarks and formulations, to be amortized over 10 years; customer relationships, to be amortized over 15 years; and a non-compete agreement, to be amortized over 5 ye ars. In addition, the Company has recorded $14,642 of goodwill, related to expected value outside its other acquired assets, all of which will be tax deductible. The results of operations of the acquired businesses and assets are included in the consolida ted statements of income from their respective acquisition dates. Transaction expenses associated with these acquisitions are included in selling, general and administrative expenses in the Company’s consolidated statements of income. Certain pro forma a nd other information is not presented, as the operations of the acquired businesses are not material to the overall operations of the Company for the periods presented. During the second quarter of 2015, the Company identified and recorded certain adjustments to the allocations of the purchase price for certain 2014 acquisitions. These adjustments were the result of the Company assessing additional information related to assets acquired and liabilities assumed during the one-year measurement period following each acquisition. As of June 30, 2015 , the allocations of the purchase price for all of the Company’s 2014 acquisitions have not been finalized and the o ne-year measurement period for each acquisition has not ended. Further adjustments may be necessary as a result of the Company’s assessment of additional information related to the fair values of assets acquired and liabilities assumed. The following tab le presents the current allocation of the purchase price of the assets acquired and liabilities assumed in all of the Company’s acquisitions in 2014: 2014 Acquisitions Current assets $ 12,413 Property, plant & equipment 4,158 Intangibles Customer lists and rights to sell 30,924 Trademarks and patents 12,606 Other intangibles 1,127 Goodwill 21,546 Other long-term assets 198 Total assets purchased 82,972 Current liabilities (4,562) Long-term liabilities (4,374) Total liabilities assumed (8,936) Cash paid for acquisitions $ 74,036 Included in the 2014 acquisitions was approximately $1,037 of cash acquired. Additionally, in June 2014, the Company acquired the remaining 49% ownership interest in its Australian affiliate, Quaker Chemical (Australasia) Pty. Limited ("QCA") for 8,000 Australian Dollars, or approximately $7,577, from its joint venture partner, Nuplex Industries. QCA is a part of the Company’s Asia/Pacific reportable operating segment. This acquisition further strengthens Quaker’s position in Australia, and allows the Company to simplify its overall corporate structure and improve its organizational efficiencies. As this acquisition was a change in an existing controlling ownership, the Company recorded $6,450 of excess purchase price over the carrying value of the nonc ontrolling interest in Additional Paid in Capital. I n July 2015, s ubsequent to the date of these financial statements , the Company acquired Ver kol, S.A. (“Verkol”), a leading specialty grease and other lubricants manufacturer based in Northern Spain for its EMEA reportable operating segment for approximately 36,455 EUR, or approximately $40,100, including net cash of approximately 9,563 EUR, or approximately $10,519. In addition, the Company expects to incur 2,590 EUR, or approximately $2,849, of tr ansaction-related expenses in the third quarter of 2015, in conjunction with this acquisiti on. Verkol is a market leader with world-class grease manufacturing capabilities and state-of-the-art R&D facilities, selling products into industrial end markets with a particular strength serving the steel industry. Also, Verkol brings unique technology in continuous casting products that will provide the Company with cross-selling opportunities to its glob al steel customer base. As of the date of these financial statements, the Company has not yet completed the allocation of the purchase price to the fair value of assets acquired and liabilities assumed, and, also, certain pro forma and other information a re not presented as the operations of the acquired business are not material to the Company for the periods presented.

As a result, the Company had no deferred compensation assets or liabilities subject to fair value measurement and accounting related to its Executive Deferred Compensation Plan on its Condensed Consolidated Balance Sheet as of June 30, 2015 . However, the Company did have $1,018 of associated liabilities, no longer subject t o fair value measurement, which will be paid out by the Company during the third quarter of 2015. The fair values of Company-owned life insurance (“COLI”) and COLI deferred compensation assets are based on quotes for like instruments with similar credit ra tings and terms. The fair values of other deferred compensation assets and liabilities are based on quoted prices in active markets. The Company did not hold Level 3 investments as of June 30, 2015 or December 31, 2014 , respectively, so related disclosures have not been included.

Commitments And Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 14 – 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 c ompensatory and other damages related to the investigation and remediation of the contamination in the groundwater. Pursuant to the settlement agreement with OCWD, ACP agreed, among other things, to operate the two groundwater treatment systems to hydraul ically contain groundwater contamination emanating 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 February 2014, ACP, OCWD and SA CRWQB, ceased operation at one of its two groundwater treatment systems, as it had met the above condition for closure. Based on the most recent modeling, it is estimated that the remaining system will operate for another six months to two years and six m onths . As of June 30, 2015 , the Company believes that the range of potential-known liabilities associated with the balance of the ACP water remediation program is approximately $200 to $870 , for which the Company has sufficient res erves. The low and high ends of the range are based on the length of operation of the treatment system as determined by groundwater modeling. Costs of operation include the operation and maintenance of the extraction well, groundwater monitoring and prog ram 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. Appro ximately $315 and $173 was accrued at June 30, 2015 and December 31, 2014 , respectively, to provide for such anticipated future environmental assessments and remediation costs. An inactive subsidiary of the Company that wa s 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 and has no remainin g assets other than the 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 continued 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 less than $3,800 (excluding costs of defense). Although the Company has al so 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 handl ed 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 aggregate limits of the polic ies. 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 challenged the applicabili ty 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 $15,000 and $20,000, 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 par ty by providing a minimum of two years prior written notice. As of June 30, 2015 , 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 . The Company believes that, if the coverage issues under the primary policies with the remaining carrier are resolved adversely to the subsidiary and all settlement proceeds were used, the subsi diary 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 assets and coverage available to the sub sidiary. 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 does 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 h ave 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 that 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 any material losses. The Company has been successful to date having claims naming it dismissed during initial p roceedings. Since the Company may be in this early 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 have 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 particular as to how they re late 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 exceeds the amount originally collected and remitted by the subsidiary. In response, the subsidiary modified its VAT invoicing and payment pro cedures to eliminate or mitigate future exposure. In 2010, three jurisdictions contacted the subsidiary and, since then, the subsidiary has either participated in an amnesty program or entered into a settlement whereby it paid a reduced portion of the amo unts owed in resolution of those jurisdictions’ claims, and no related accruals exist as of June 30, 2015 or December 31, 2014 . In late 2013, an additional jurisdiction issued an assessment against the subsidiary for certain tax years leading to a net charge of $796 , which represented the Company’s best estimate of the amount that ultimately may be paid . The subsidiary has filed an appeal of the assessment alleging certain errors by such jurisdiction related to the assessment. I n analyzing the subsidiary’s exposure, it is difficult to estimate both the probability and the amount of any potential liabilities due to a number of factors, including: the decrease in exposure over time due to applicable statutes of limitations and acti ons taken by the subsidiary, the joint liability of customers and suppliers for a portion of the VAT, the availability of a VAT refund for VAT incorrectly paid through an administrative process, any amounts which may have been or will be paid by customers, as well as the timing and structure of any tax amnesties or settlements. In addition, interest and penalties on any VAT due can be a multiple of the base tax. The subsidiary may contest any tax assessment administratively and/or judicially for an extended period of time, but may ultimately resolve its disputes through participation in tax amnesty programs, which are a common practice for settling tax disputes in the jurisdictions in question and which have historically occurred on a regular basis, resulting in significant red uctions of interest and penalties. Also, the timing of payments and refunds of VAT may not be contemporaneous, and, if additional VAT is owed, it may not be fully recoverable from customers. The charges taken by the Company in 2013 assume a successful re covery of the VAT incorrectly paid, as well as reductions in interest and penalties from anticipated future amnesty programs or settlements. On a similar basis, if all other potentially impacted jurisdictions were to initiate audits and issue assessments, the remaining exposure, net of refunds, could be from $0 to $3,400 with one jurisdiction representing approximately 85 percent of this additional exposure, assuming the continued availability of future amnesty programs or settlements t o reduce the interest and penalties. If there are future assessments but no such future amnesty programs or settlements, the potential exposure could be higher. The Company is party to other litigation which management currently believes will not have a m aterial adverse effect on the Company’s results of operations, cash flows or financial condition.

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 $15,000 and $20,000, 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 June 30, 2015, 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.
