Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Note 1 – Condensed Financial Information

As used in these Notes to Condensed Consolidated Financial Statements, the terms “Quaker”, “Quaker Houghton”, the “Company”, “we” and “our” refer to Quaker Chemical Corporation (doing business as Quaker Houghton), its subsidiaries, and associated companies, unless the context otherwise requires. As used in these Notes to Condensed Consolidated Financial Statements, the term Legacy Quaker refers to the Company prior to closing of its combination with Houghton International, Inc. (“Houghton”) (herein referred to as the “Combination”). 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 Securities 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 opinion of management, the financial statements reflect all adjustments which are of a normal and recurring nature and are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the three and nine months ended September 30, 2019, respectively, are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K, as amended by the Company’s Form 10-K/A, for the year ended December 31, 2018.

Hyper-inflationary economies

Economies that have a cumulative three-year rate of inflation exceeding 100% are considered hyper-inflationary under U.S. GAAP. A legal entity that operates within an economy deemed to be hyper-inflationary is required to remeasure its monetary assets and liabilities to the applicable published exchange rates and record the associated gains or losses resulting from the remeasurement directly to the Condensed Consolidated Statements of Operations. The Company has a 50-50 joint venture in a Venezuelan affiliate, Kelko Quaker Chemical, S.A. Venezuela’s economy has been considered hyper-inflationary under U.S. GAAP since 2010. During the three and nine months ended September 30, 2018, the Company recorded remeasurement losses of less than $0.1 million and $0.3 million, respectively, associated with the applicable currency conversions related to Venezuela. These losses were recorded within equity in net income of associated companies in the Company’s Condensed Consolidated Statements of Operations. Due to heightened foreign exchange controls and restrictions currently present within Venezuela, during the third quarter of 2018 the Company concluded that it no longer had significant influence over this affiliate. Prior to this determination, the Company historically accounted for this affiliate under the equity method. As of September 30, 2019 and December 31, 2018, the Company has no remaining carrying value for its investment in Kelko Venezuela.

Based on various indices or index compilations currently being used to monitor inflation in Argentina as well as recent economic instability, effective July 1, 2018, Argentina’s economy was considered hyper-inflationary under U.S. GAAP. As a result, the Company began applying hyper-inflationary accounting with respect to the Company's wholly owned Argentine subsidiary beginning July 1, 2018. In addition, Houghton has an Argentine subsidiary to which hyper-inflationary accounting also is applied. As of, and for the nine months ended September 30, 2019, the Company's Argentine subsidiaries represented less than 1% of the Company’s consolidated total assets and net sales, respectively. During the three and nine months ended September 30, 2019, the Company recorded $0.7 million and $0.9 million, respectively, of remeasurement losses associated with the applicable currency conversions related to Argentina. Comparatively, during each of the three and nine months ended September 30, 2018, the Company recorded approximately $0.5 million of remeasurement losses associated with the applicable currency conversion related to Argentina. These losses were recorded within foreign exchange gains (losses), net, which is a component of other income (expense), net, in the Company’s Condensed Consolidated Statements of Operations.

Business Combination Separately Recognized Transaction [Abstract]

Business Combination Disclosure [Text Block]

Note 2 – Business Combinations

Houghton

On August 1, 2019, the Company completed the Combination with Houghton, whereby the Company acquired all of the issued and outstanding shares of Houghton from Gulf Houghton Lubricants, Ltd. and certain other selling shareholders in exchange for a combination of cash and shares of the Company’s common stock in accordance with the share purchase agreement dated April 4, 2017. Houghton is a leading global provider of specialty chemicals and technical services for metalworking and other industrial applications. Combining Quaker and Houghton’s product and service offerings will allow Quaker Houghton to better serve its customers in its various end markets.

The Combination was subject to certain regulatory and shareholder approvals. At a shareholder meeting held during 2017, the Company’s shareholders approved the issuance of new shares of the Company’s common stock at closing of the Combination. Also in 2017, the Company received regulatory approvals for the Combination from China and Australia. The Company received regulatory approvals from the European Commission (“EC”) during the second quarter of 2019 and the U.S. Federal Trade Commission (“FTC”) in July 2019. The approvals from the FTC and the EC required the concurrent divestiture of certain steel and aluminum related product lines of Houghton, which were sold by Houghton on August 1, 2019 for approximately $37 million in cash. The final remedy agreed with the EC and the FTC was consistent with the Company’s previous expectation that the total divested product lines would be approximately 3% of the combined company’s net sales.

The following table summarizes the fair value of consideration transferred in the Combination:

Cash transferred to Houghton shareholders (a)		$	170,829
Cash paid to extinguish Houghton debt obligations			702,556
Fair value of common stock issued as consideration (b)			789,080
	Total fair value of consideration transferred	$	1,662,465

(a)A portion is held in escrow by a third party, subject to indemnification rights that lapse upon the achievement of certain milestones.

(b)Amount was determined based on 4.3 million shares, comprising 24.5% of the common stock of the Company at closing, and the closing price per share of Quaker Chemical Corporation common stock of $182.27 on August 1, 2019.

The Company accounted for the Combination under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets, at their fair value on the acquisition date. 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 requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, royalty rates, asset lives and market multiples, among other items. Fair values were determined by management, using a variety of methodologies and resources, including external independent valuation experts. The valuation methods consisted of physical appraisals, discounted cash flow analyses, excess earnings, relief from royalty, and other appropriate valuation techniques to determine the fair value of assets acquired and liabilities assumed.

The following table presents the preliminary estimated fair values of Houghton net assets acquired:

Cash and cash equivalents		$	75,821
Accounts receivable, net			179,745
Inventories, net			95,193
Prepaid expenses and other assets			11,373
Deferred tax assets			8,703
Property, plant and equipment			125,099
Right of use lease assets			10,747
Investments in associated companies			69,683
Other non-current assets			1,368
Intangible assets			1,022,500
Goodwill			483,921
	Total assets purchased		2,084,153
Short-term borrowings, not refinanced at closing			9,297
Accounts payable, accrued expenses and other current liabilities			152,829
Deferred tax liabilities			213,779
Long-term lease liabilities			6,655
Other non-current liabilities			39,128
	Total liabilities assumed		421,688
	Total consideration paid for Houghton		1,662,465
	Less: cash acquired		75,821
	Less: fair value of common stock issued as consideration		789,080
	Net cash paid for Houghton	$	797,564

Investments in associated companies presented in the table above represents the Company’s initial fair value estimate of its 50% interest in a Houghton joint venture in Korea. The Company accounts for this interest under the equity method of accounting. The Company allocated $1,022.5 million of the purchase price to intangible assets, comprised of $242.0 million of trademarks and formulations, to which management has assigned indefinite lives; $671.4 million of customer relationships, to be amortized over 16 to 18 years; and $109.1 million of existing product technology, to be amortized over 20 years. In addition, the Company recorded $483.9 million of goodwill related to expected value not allocated to other acquired assets, none of which will be tax deductible. Factors contributing to the purchase price that resulted in goodwill included the acquisition of management, technology, intellectual property, business processes and personnel that will allow Quaker Houghton to better serve its customers. The expanded portfolio is expected to generate significant cross-selling opportunities and allow further expansion into growth markets such as India, Korea, Brazil and Mexico.

As of September 30, 2019, the allocation of the purchase price for the Combination has not been finalized and the one-year measurement period has not ended. Further adjustments may be necessary as a result of the Company’s on-going assessment of additional information related to the fair value of assets acquired and liabilities assumed.

Commencing August 1, 2019, the Company’s Condensed Consolidated Statements of Operations included the results of Houghton. Net sales of Houghton subsequent to closing of the Combination and included in the Company’s Condensed Consolidated Statements of Operations were $119.5 million. The following unaudited pro forma consolidated financial information has been prepared as if the Combination had taken place on January 1, 2018. The unaudited pro forma results include certain adjustments to each company’s historical actual results, including: (i) additional depreciation and amortization expense based on the initial estimates of fair value step up and estimated useful lives of depreciable fixed assets, definite-lived intangible assets and investment in associated companies acquired; (ii) adoption of required accounting guidance and alignment of related accounting policies, (iii) elimination of transactions between Quaker and Houghton; (iv) elimination of results associated with the divested product lines; (v) adjustment to interest expense, net, to reflect the impact of the financing and capital structure of the combined Company; and (vi) adjustment for certain Combination and other acquisition-related costs to reflect such costs as if they were incurred in the period immediately following the pro-forma closing of the Combination on January 1, 2018. The adjustments described in (vi) include an expense recorded in costs of goods sold (“COGS”) associated with selling inventory acquired in the Combination which was adjusted to fair value as part of purchase accounting, restructuring expense incurred associated with the Company’s global restructuring program initiated post-closing of the Combination and certain other integration costs incurred post-closing included in combination and other acquisition-related expenses. These costs have been presented in the pro forma results as if they were incurred during the nine months ended September 30, 2018. Pro forma results are not necessarily indicative of the results that would have occurred if the acquisition had occurred on the date indicated, or that may result in the future for various reasons, including the potential impact of revenue and cost synergies on the business.

Combination and other acquisition-related expenses have been and are expected to continue to be significant. The Company incurred total costs of $15.1 million and $25.9 million during the three and nine months ended September 30, 2019, and $3.8 million and $14.4 million during the three and nine months ended September 30, 2018, respectively, related to the Combination and other acquisition-related activities. These costs included certain legal, financial and other advisory and consultant costs related to due diligence, regulatory approvals and integration planning as well as professional fees associated with closing the Combination. These costs also include interest costs to maintain the bank commitment (“ticking fees”) for the Combination during each of three and nine months ended September 30, 2019 and 2018, and specifically during the nine months ended September 30, 2018, a gain on the sale of an available-for-sale asset. As of September 30, 2019 and December 31, 2018, the Company had current liabilities related to the Combination and other acquisition-related activities of $6.8 million and $8.2 million, respectively, primarily recorded within other current liabilities on its Condensed Consolidated Balance Sheets.

Norman Hay

On October 1, 2019, the Company completed its acquisition of the operating divisions of Norman Hay plc, a private U.K. company that provides specialty chemicals, operating equipment, and services to industrial end markets, for a purchase price of 80.0 million GBP or approximately $98 million, subject to certain normal and routine post-closing adjustments. The results of operations of the acquired operating divisions of Norman Hay plc are not included in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2019, because the date of closing was after September 30, 2019. Transaction expenses associated with this acquisition that were incurred during the three and nine months ended September 30, 2019 are included in Combination and other acquisition-related expenses in the Company’s Condensed Consolidated Statements of Operations. A preliminary purchase price allocation of assets acquired and liabilities assumed has not been presented as that information is not available as of the date of these Condensed Consolidated Financial Statements.

Other Acquisitions

In March 2018, the Company purchased certain formulations and product technology for the mining industry for $1.0 million. The Company allocated the entire purchase price to intangible assets representing formulations and product technology, to be amortized over 10 years. In accordance with the terms of the applicable purchase agreement, $0.5 million of the purchase price was paid at signing, and the remaining $0.5 million of the purchase price was paid during the first quarter of 2019.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Note 3 – Recently Issued Accounting Standards

The Financial Accounting Standards Board (“FASB”) issued an accounting standard update in August 2018 that modifies certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments in this accounting standard update remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of certain disclosures, and add new disclosure requirements as relevant. The guidance within this accounting standard update is effective for annual periods beginning after December 15, 2020, and should be applied retrospectively to all periods presented. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation.

The FASB also issued an accounting standard update in August 2018 that clarifies the accounting for implementation costs incurred in a cloud computing arrangement under a service contract. This guidance generally aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement under a service contract with the requirements for capitalizing implementation costs related to internal-use software. The guidance within this accounting standard update is effective for annual periods beginning after December 15, 2019 and may be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation.

The FASB issued an additional accounting standard update in August 2018 that modifies certain disclosure requirements for fair value measurements. The guidance removes certain disclosure requirements regarding transfers between levels of the fair value hierarchy as well as certain disclosures related to the valuation processes for certain fair value measurements. Further, the guidance added certain disclosure requirements including unrealized gains and losses and significant unobservable inputs used to develop certain fair value measurements. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2019, and may be applied prospectively in the initial year of adoption or retrospectively to all periods presented, depending on the amended disclosure requirement. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation.

The FASB issued an accounting standard update in February 2018 that allows a reclassification from accumulated other comprehensive (loss) income (“AOCI”) to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (“U.S. Tax Reform”) enacted in December 2017. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2018, and may be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in U.S. Tax Reform is recognized. Early adoption was permitted. The Company adopted this guidance in the first quarter of 2019, as required, but elected not to reclassify any stranded tax effects resulting from U.S. Tax Reform, therefore adoption of this guidance did not have any impact on its financial statements.

The FASB issued an accounting standard update in June 2016 related to the accounting for and disclosure of credit losses. In May 2019, the FASB issued an accounting standard update to provide targeted transition relief to increase comparability of financial statements. The guidance introduces a new model for recognizing credit losses on financial instruments, including customer accounts receivable, based on an estimate of current expected credit losses. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2019, and aspects of the guidance which may be applicable to the Company should be applied on a modified retrospective basis. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation.

The FASB issued an accounting standard update in February 2016 regarding the accounting and disclosure for leases. During 2018 and 2019, the FASB issued a series of accounting standard updates to clarify and expand on the original 2016 implementation guidance, including providing an accounting policy election for lessors, certain targeted improvements around comparative reporting requirements and accounting for lease and non-lease components by lessors as well as other technical corrections and improvements. The amendments in these 2018 and 2019 updates did not change the core principles of the guidance previously issued in February 2016. The guidance within all of the leasing accounting standard updates were effective for annual and interim periods beginning after December 15, 2018, and should have been applied on a modified retrospective basis, applying the transition requirements either (a) at the beginning of the earliest period presented in the financial statements in the year of adoption (January 1, 2017) or (b) in the period of adoption (January 1, 2019). Early adoption was permitted.

As part of the Company’s implementation planning and its impact assessment related to the new lease accounting guidance, the Company developed a detailed project plan, identified and established a cross-functional implementation team and developed pre-adoption internal controls. In addition, the Company gathered an inventory of the Company’s outstanding leases globally, performed certain review procedures to ensure completeness of its lease population and abstracted required information from its lease population for inclusion within the Company’s leasing software. The Company performed similar implementation planning and impact assessment procedures as it relates to Houghton.

For legacy Quaker, the Company adopted the guidance in the first quarter of 2019, as required, electing to use a modified retrospective transition approach and applied transition requirements as of January 1, 2019, as permitted. Subsequent to the acquisition of Houghton, previously a private company, the Company adopted the guidance and elected to use a modified retrospective transition approach and applied transition requirements as of August 1, 2019. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. In addition, the Company elected to apply certain of the permitted transition practical expedients within the new lease accounting related to lease identification, lease classification, and initial direct costs. The Company made certain accounting policy elections as a result of adopting the new lease accounting guidance, which include not separating lease and non-lease components, applying a portfolio approach in the development of the Company’s discount rates, applying the short-term lease exemption and establishing a capitalization threshold policy.

Adoption of the lease accounting guidance did not have a material impact on the Company’s reported earnings or cash flows, however, adoption did result in a material impact to the Company’s balance sheet to establish the right of use lease assets and associated lease liabilities. As of January 1, 2019, legacy Quaker recorded a cumulative effect of an accounting change that resulted in an increase to its right of use lease assets of $27.3 million, an increase of $5.3 million of short-term lease liabilities and $21.4 million of long-term lease liabilities, a decrease in property, plant and equipment, net of $1.1 million, a decrease in other current liabilities of $0.4 million and a decrease to retained earnings of less than $0.1 million. The cumulative effect of an accounting change related to Houghton as of August 1, 2019 resulted in an increase to its right of use lease assets of $10.7 million, and an increase of $4.1 million of short-term lease liabilities and approximately $6.6 million of long-term lease liabilities.

Segment Reporting Disclosure [Text Block]

Note 4 – Business Segments

The Company’s reportable segments reflect 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 assesses its performance. During the third quarter of 2019 and in connection with the Combination, the Company reorganized its executive management team to align with its new business structure, which reflects the method by which the Company assesses its performance and allocates its resources. The Company’s new reportable segment structure includes four segments: (i) Americas; (ii) Europe, Middle East and Africa (“EMEA”); (iii) Asia/Pacific; and (iv) Global Specialty Businesses. The three geographic segments are composed of the net sales and operations in each respective region, excluding net sales and operations managed globally by the Global Specialty Businesses segment, which includes the Company’s container, metal finishing, mining, offshore, specialty coatings and specialty grease businesses. All prior period information for legacy Quaker has been recast to reflect these four segments as the Company’s new reportable segments. Prior to the Company’s re-segmentation during the third quarter of 2019, the Company’s historical reportable segments were four geographic regions: (i) North America; (ii) EMEA; (iii) Asia/Pacific; and (iv) South America.

Though the Company changed its reportable segments in the third quarter of 2019, the calculation of the reportable segments’ measures of earnings remains otherwise generally consistent with past practices. Segment operating earnings for the Company’s reportable segments are comprised of net sales less COGS and selling, general and administrative expenses (“SG&A”) directly related to the respective segment’s product sales. Operating expenses not directly attributable to the net sales of each respective segment are excluded from segment operating earnings, which includes certain corporate and administrative costs, Combination and other acquisition-related expenses, restructuring and related activities and COGS related to acquired Houghton inventory sold, which was adjusted to fair value as a part of purchase accounting. Other items not specifically identified with the Company’s reportable segments include interest expense, net and other income (expense), net.

The following table presents information about the performance of the Company’s reportable segments for the three and nine months ended September 30, 2019 and 2018:

Note 5 – Net Sales and Revenue Recognition

Business Description

The Company develops, produces, and markets a broad range of formulated chemical specialty products and offers chemical management services (“Fluidcare”) for various heavy industrial and manufacturing applications throughout its four segments. The Combination increased the Company’s addressable metalworking, metals and industrial end markets, which include: steel, aluminum, aerospace and defense, transportation and OEM, transportation components, offshore, architectural aluminum, fire-resistant hydraulics, die casting, tube and pipe, can and container, mining, specialty coatings and specialty greases. The Combination also strengthened the product portfolio of the combined Company. The major product lines of Quaker Houghton include metal removal and cleaning fluids, corrosion preventatives and cleaners, metal drawing and forming fluids, die cast mold releases, heat treatment and quenchants, metal forging fluids, hydraulic fluids, specialty greases, offshore control fluids, rolling lubricants, rod and wire drawing and surface treatments.

A substantial portion of the Company’s sales worldwide are made directly through its own employees and its Fluidcare programs, with the balance being handled through distributors and agents. The Company’s employees visit the plants of customers regularly, work on site, and, through training and experience, identify production needs which can be resolved or alleviated either by adapting the Company’s existing products or by applying new formulations developed in its laboratories. The chemical specialty industry comprises many companies similar in size to the Company, as well as companies larger and smaller than Quaker Houghton. The

offerings of many of the Company’s competitors differ from those of Quaker Houghton; some offer a broad portfolio of fluids, including general lubricants, while others have a more specialized product range. All competitors provide different levels of technical services to individual customers. Competition in the industry is based primarily on the ability to provide products that meet the needs of the customer, render technical services and laboratory assistance to the customer and, to a lesser extent, on price.

As part of the Company’s Fluidcare business, 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, revenue is recognized on a net reporting basis generally at the amount of the administrative fee earned by the Company for ordering the goods. In determining whether the Company is acting as a principal or an agent in each arrangement, the Company considers whether it is primarily responsible for the obligation to provide the specified good, has inventory risk before the specified good has been transferred to the customer and has discretion in establishing the prices for the specified goods. The Company transferred third-party products under arrangements recognized on a net reporting basis of $13.6 million and $34.4 million for the three and nine months ended September 30, 2019, respectively, and $11.7 million and $35.8 million for the three and nine months ended September 30, 2018, respectively.

A significant portion of the Company’s revenues are realized from the sale of process fluids and services to manufacturers of steel, automobiles, aircraft, appliances, and durable goods, and, therefore, the Company is subject to the same business cycles as those experienced by these manufacturers and their customers. The Company’s financial performance is generally correlated to the volume of global production within the industries it serves, rather than discretely related to the financial performance of such industries. Furthermore, steel customers typically have limited manufacturing locations compared to metalworking customers and generally use higher volumes of products at a single location. As previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018, during 2018 the Company’s five largest customers (each composed of multiple subsidiaries or divisions with semiautonomous purchasing authority) accounted for approximately 17% of consolidated net sales, with its largest customer accounting for approximately 8% of consolidated net sales.

Revenue Recognition Model

The Company applies the FASB’s guidance on revenue recognition which requires the Company to recognize revenue in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services transferred to its customers. To do this, the Company applies the five-step model in the FASB’s guidance, which requires the Company to: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation.

The Company identifies a contract with a customer when a sales agreement indicates approval and commitment of the parties; identifies the rights of the parties; identifies the payment terms; has commercial substance; and it is probable that the Company will collect the consideration to which it will be entitled in exchange for the goods or services that will be transferred to the customer. In most instances, the Company’s contract with a customer is the customer’s purchase order. For certain customers, the Company may also enter into a sales agreement which outlines a framework of terms and conditions which apply to all future and subsequent purchase orders for that customer. In these situations, the Company’s contract with the customer includes both the sales agreement and the specific customer purchase order. Because the Company’s contract with a customer is typically for a single transaction or customer purchase order, the duration of the contract is almost always one year or less. As a result, the Company has elected to apply certain practical expedients and omit certain disclosures of remaining performance obligations for contracts that have an initial term of one year or less as permitted by the FASB.

The Company identifies a performance obligation in a contract for each promised good or service that is separately identifiable from other obligations in the contract and for which the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer. The Company determines the transaction price as the amount of consideration it expects to be entitled to in exchange for fulfilling the performance obligations, including the effects of any variable consideration, significant financing elements, amounts payable to the customer or noncash consideration. For any contracts that have more than one performance obligation, the Company allocates the transaction price to each performance obligation in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for satisfying each performance obligation.

In accordance with the last step of the FASB’s guidance, the Company recognizes revenue when, or as, it satisfies the performance obligation in a contract by transferring control of a promised good or providing the service to the customer. The Company recognizes revenue over time whenever the customer simultaneously receives and consumes the benefits provided by the Company’s performance; the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or the Company’s performance does not create an asset with an alternative use to the entity, and the entity has an

enforceable right to payment, including a profit margin, for performance completed to date. For performance obligations not satisfied over time, the Company determines the point in time at which a customer obtains control of an asset and the Company satisfies a performance obligation by considering when the Company has a right to payment for the asset; the customer has legal title to the asset; the Company has transferred physical possession of the asset; the customer has the significant risks and rewards of ownership of the asset; or the customer has accepted the asset.

The Company typically satisfies its performance obligations and recognizes revenue at a point in time for product sales, generally when products are shipped or delivered to the customer, depending on the terms underlying each arrangement. In circumstances where the Company’s products are on consignment, revenue is generally recognized upon usage or consumption by the customer. For any Fluidcare or other services provided by the Company to the customer, the Company typically satisfies its performance obligations and recognizes revenue over time, as the promised services are performed. The Company uses input methods to recognize revenue over time related to these services, including labor costs and time incurred. The Company believes that these input methods represent the most indicative measure of the Fluidcare or other service work performed by the Company.

Other Considerations

The Company does not have standard payment terms for all customers globally, however the Company’s general payment terms require customers to pay for products or services provided after the performance obligation is satisfied. The Company does not have significant financing arrangements with its customers. The Company does not have significant amounts of variable consideration in its contracts with customers and where applicable, the Company’s estimates of variable consideration are not constrained. The Company records certain third-party license fees in other income (expense), net, in its Condensed Consolidated Statements of Operations, which generally include sales-based royalties in exchange for the license of intellectual property. These license fees are recognized in accordance with their agreed-upon terms and when performance obligations are satisfied, which is generally when the third party has a subsequent sale.

Practical Expedients and Accounting Policy Elections

The Company has made certain accounting policy elections and elected to use certain practical expedients as permitted by the FASB in applying the guidance on revenue recognition. It is the Company’s policy not to adjust the promised amount of consideration for the effects of a significant financing component because the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to the customer and when the customer pays for that good or service will be one year or less. In addition, it is the Company’s policy to expense costs to obtain a contract as incurred when the expected period of benefit, and therefore the amortization period, is one year or less. It is also the Company’s accounting policy to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer, including sales, use, value added, excise and various other taxes. Lastly, the Company has elected to account for shipping and handling activities that occur after the customer has obtained control of a good as a fulfilment cost, rather than an additional promised service.

Contract Assets and Liabilities

The Company recognizes a contract asset or receivable on its Condensed Consolidated Balance Sheet when the Company performs a service or transfers a good in advance of receiving consideration. A receivable is the Company’s right to consideration that is unconditional and only the passage of time is required before payment of that consideration is due. A contract asset is the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer. The Company had no material contract assets recorded on its Condensed Consolidated Balance Sheets as of September 30, 2019 or December 31, 2018.

A contract liability is recognized when the Company receives consideration, or if it has the unconditional right to receive consideration, in advance of performance. A contract liability is the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration, or a specified amount of consideration is due, from the customer. The Company’s contract liabilities primarily represent deferred revenue recorded for customer payments received by the Company prior to the Company satisfying the associated performance obligation. Deferred revenues are presented within other current liabilities in the Company’s Condensed Consolidated Balance Sheets. The Company had approximately $2.4 million and $1.3 million of deferred revenue as of September 30, 2019 and December 31, 2018, respectively. During the nine months ended September 30, 2019, the Company satisfied the associated performance obligations and recognized revenue of $1.3 million related to advance customer payments.

Disaggregated Revenue

The Company sells its various industrial process fluids, its chemical specialties and its technical expertise as a global product portfolio. The Company generally manages and evaluates its performance by segment first, and then by customer industry, rather than by individual product lines. The Company has provided annual net sales information for its product lines greater than 10% in its previously filed Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018. Those annual percentages are generally consistent with the current year’s net sales by product line, excluding the Combination. Also, net sales of each of the Company’s major product lines are generally spread throughout all three of the Company’s geographic segments, and in most cases, approximately proportionate to the level of total sales in each region.

The following tables disaggregate the Company’s net sales by segment, region, customer industry, and timing of revenue recognized for the three and nine months ended September 30, 2019 and 2018. The Company has made certain reclassifications of disaggregated customer industry disclosures for the three and nine months ended September 30, 2018 to conform with the Company’s current period customer industry segmentation.

Note 6 – Leases

The Company determines if an arrangement is a lease at its inception. This determination generally depends on whether the arrangement conveys the right to control the use of an identified fixed asset explicitly or implicitly for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the rights to direct the use of, and obtains substantially all of the economic benefits from the use of, the underlying asset. Lease expense for variable leases and short-term leases is recognized when the obligation is incurred.

The Company has operating leases for certain facilities, vehicles and machinery and equipment with remaining lease terms up to 8 years. In addition, the Company has certain land use leases with remaining lease terms up to 96 years. The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by an option to extend the lease that the Company is reasonably certain it will exercise. Operating leases are included in right of use lease assets, other current liabilities and long-term lease liabilities on the Condensed Consolidated Balance Sheet. Right of use lease assets and liabilities are recognized at each lease’s commencement date based on the present value of its lease payments over its respective lease term. The Company uses the stated borrowing rate for a lease when readily determinable. When a stated borrowing rate is not available in a lease agreement, the Company uses its incremental borrowing rate based on information available at the lease’s commencement date to determine the present value of its lease payments. In determining the incremental borrowing rate used to present value each of its leases, the Company considers certain information including fully secured borrowing rates readily available to the Company and its subsidiaries. The Company has immaterial finance leases, which are included in property, plant and equipment, current portion of long-term debt and long-term debt on the Condensed Consolidated Balance Sheet.

Operating lease expense is recognized on a straight-line basis over the lease term. Operating lease expense for the three and nine months ended September 30, 2019 was $2.5 million and $6.0 million, respectively. Short-term lease expense for the three and nine months ended September 30, 2019 was $0.5 million and $0.8 million, respectively. The Company has no material variable lease costs or sublease income for the three or nine months ended September 30, 2019. Cash paid for operating leases during the nine months ended September 30, 2019 was $5.9 million. Subsequent to the Company’s adoption of the new lease accounting guidance, the Company recorded new right of use lease assets and associated lease liabilities of $1.4 million during the nine months ended September 30, 2019. Supplemental balance sheet information related to the Company’s leases is as follows:

Pursuant to the Company’s adoption of the new lease accounting guidance using a modified retrospective transition approach, as permitted, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. As previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018, the following table presents the Company’s future minimum rental commitments under operating leases as of December 31, 2018:

Note 7 – Restructuring and Related Activities

During the third quarter of 2019, the Company’s management approved and the Company initiated a global restructuring plan (the “QH Program”) as part of its plan to realize certain cost synergies associated with the Combination. The QH Program will include restructuring and associated severance costs to reduce total headcount by approximately 275 people globally and plans for the closure of certain manufacturing and non-manufacturing facilities. The exact timing and total costs associated with the QH Program will depend on a number of factors and is subject to change, however, the Company currently expects reduction in headcount and site closures to occur over the next two years under the QH Program and estimates that total costs related to the QH Program will approximate one-time the anticipated cost synergies realized. Employee separation benefits will vary depending on local regulations within certain foreign countries and will include severance and other benefits.

Activity in the Company’s accrual for restructuring under the QH Program for the nine months ended September 30, 2019 is as follows:

		QH Program
Accrued restructuring as of December 31, 2018		$	—
	Restructuring expense		24,045
	Cash payments		(4,645)
	Currency translation adjustments		(80)
Accrued restructuring as of September 30, 2019		$	19,320

There were no QH Program accrued restructuring liabilities as of December 31, 2018 and no restructuring expense during the nine months ended September 30, 2018.

The Company recognized the following share-based compensation expense in SG&A in its Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2019 and 2018:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,

Director stock ownership plan		27		31		81		93
Total share-based compensation expense	$	1,370	$	872	$	3,042	$	2,847

During the third quarter of 2019, the Company granted stock options under its long-term incentive plan (“LTIP”) that are subject only to time-based vesting over up to a three-year period. For the purposes of determining the fair value of stock option awards, the Company used the Black-Scholes option pricing model and the assumptions set forth in the table below:

Number of options granted	51,610
Dividend yield	1.12	%
Expected volatility	26.29	%
Risk-free interest rate	1.52	%
Expected term (years)	4.0

The fair value of these options is amortized on a straight-line basis over the vesting period. As of September 30, 2019, unrecognized compensation expense related to all options granted was $2.0 million, to be recognized over a weighted average remaining period of 1.4 years.

During the first nine months of 2019, the Company granted 40,382 nonvested restricted shares and 6,060 nonvested restricted stock units under its long-term incentive plan, subject only to time-based vesting, generally over a one to three-year period. The fair value for these grants 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 of these awards for expected forfeitures based on historical experience. As of September 30, 2019, unrecognized compensation expense related to the nonvested restricted shares was $6.5 million, to be recognized over a weighted average remaining period of 2.1 years, and unrecognized compensation expense related to nonvested restricted stock units was $0.9 million, to be recognized over a weighted average remaining period of 2.0 years.

The Company previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018 that the Company began the process of terminating Quaker’s primary non-contributory U.S. pension plan (the “U.S. Pension Plan”) during the fourth quarter of 2018. As part of this process, and considering the fully funded status of the U.S. Pension Plan, the asset allocation of the U.S. Pension Plan was adjusted modeling a glide path that is more heavily allocated to fixed income securities with lengthened durations to match the projected liabilities. As a result, the expected return on plan assets declined during the three and nine months ended September 30, 2019 compared to the three and nine months ended September 30, 2018. In order to terminate the U.S. Pension Plan in accordance with Internal Revenue Service (“I.R.S.”) and Pension Benefit Guaranty Corporation requirements, the Company will be required to fully fund the U.S. Pension Plan on a termination basis and will commit to contribute additional assets if necessary, to do so. The amount necessary to do so is not yet known but is currently estimated to be between $0 and $10 million. In addition, the Company expects to record a non-cash pension settlement charge at plan termination. This settlement charge will include the immediate recognition into expense of the related unrecognized losses within AOCI on the balance sheet as of the plan termination date. The Company does not have a current estimate for this future settlement charge, however, the gross AOCI related to the U.S. Pension Plan was approximately $18.5 million as of September 30, 2019. During the third quarter of 2019, the Company received a favorable termination determination letter from the I.R.S. and has amended the Plan to comply with final regulations of the Internal Revenue Code. The Company currently estimates that the U.S. Pension Plan termination will be completed during 2020.

Employer Contributions

The Company previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018 that it expected to make minimum cash contributions of approximately $6 million to its legacy Quaker pension and other postretirement benefit plans in 2019. As of September 30, 2019, approximately $4 million of contributions have been made to the Company’s legacy Quaker pension and other postretirement benefit plans.

Houghton Pension Plans

In connection with the Combination, the Company assumed all of Houghton’s defined benefit pension plans. The pension plans cover certain U.S. salaried and hourly employees (“Houghton U.S. Plans”) as well as certain employees in the U.K., France and Germany (“Non-U.S. Plans”). The Houghton U.S. Plans provide benefits based on an employee’s years of service and compensation received for the highest five consecutive years of earnings. Houghton management made the decision to freeze benefits for non-union employees as of March 31, 2009 for the Houghton U.S. Plans. The Non-U.S. Plans provide benefits based on a formula of years of service and a percentage of compensation which varies among the Non-U.S. Plans. Houghton management made the decision to freeze its U.K. Non-U.S. plan benefits as of May 1, 2013. Subsequent to closing the Combination, during the nine months ended September 30, 2019, the Company made approximately $1 million of contributions to the Houghton U.S. and Non-U.S. Plans, and expects to contribute an additional approximately $1 million to these plans over the remainder of 2019. As of September 30, 2019, the acquired pension balance for these plans was $24.1 million, which is recorded within other current and other non-current liabilities on the Company’s Condensed Consolidated Balance Sheet.

In connection with the Combination, the Company now contributes to a multiemployer defined benefit pension plan under terms of a collective bargaining union contract (the Cleveland Bakers and Teamsters Pension Fund). The expiration date of the collective bargaining contract is May 1, 2022. As of January 1, 2018, the last valuation date available for the multiemployer plan, total plan liabilities were approximately $592 million. As of December 31, 2018, the multiemployer pension plan had total plan assets of approximately $315 million. The Company’s contribution rate to the multiemployer pension plan is specified in the collective

bargaining union contract and contributions are made to the plan based on its union employee payroll. The Company contributed less than $0.1 million during the three and nine months ended September 30, 2019. While the Company may also have additional liabilities imposed by law as a result of its participation in the multiemployer defined benefit pension plan, there is no liability as of September 30, 2019. The Employee Retirement Income Security Act of 1974, as amended by the Multi-Employer Pension Plan Amendments Act of 1980, imposes certain contingent liabilities upon an employer who is a contributor to a multiemployer pension plan if the employer withdraws from the plan or the plan is terminated or experiences a mass withdrawal.

The Pension Protection Act of 2006 (the “PPA”) also added special funding and operational rules generally applicable to plan years beginning after 2007 for multiemployer plans with certain classifications based on a multitude of factors (including, for example, the plan’s funded percentage, cash flow position and whether the plan is projected to experience a minimum funding deficiency). The plan to which the Company contributes is in “critical” status. Plans in the “critical” status classification must adopt measures to improve their funded status through a funding improvement or rehabilitation plan which may require additional contributions from employers (which may take the form of a surcharge on benefit contributions) and/or modifications to retiree benefits. The amount of additional funds that the Company may be obligated to contribute to the plan in the future cannot be estimated as such amounts will be likely based on future levels of work that require the specific use of those union employees covered by the plan, and the amount of that future work and the number of affected employees that may be needed is not reasonably estimable.

Note 11 – Income Taxes and Uncertain Income Tax Positions

The Company’s effective tax rate for the three and nine months ended September 30, 2019 was 27.6% and 22.9%, respectively, compared to 18.5% and 21.2%, respectively, for the three and nine months ended September 30, 2018. These effective tax rates include the impacts of certain Combination and other acquisition-related non-deductible costs in all periods presented. In addition, these effective tax rates include certain tax adjustments recorded to decrease the Company’s fourth quarter of 2017 initial estimate of the one-time charge on deemed repatriation of undistributed earnings as part of the U.S. Tax Reform. The Company’s effective tax rate for the three months ended September 30, 2019 includes the cumulative year-to-date tax benefit recorded during the third quarter of 2019 as a result of one of its subsidiaries receiving approval for the renewal of a concessionary 15% tax rate compared to its 25% statutory tax rate. The concessionary tax rate was available to the Company’s subsidiary during all quarters of 2018. In addition, the effective tax rates in the three and nine months ended September 30, 2019 also include incremental withholding tax expense associated with the assumed repatriation of previously untaxed current earnings and profits of certain of the Company’s foreign subsidiaries, partially offset by favorable return to provision adjustments in the current year and certain share-based compensation-related tax benefits for deductions in excess of compensation cost associated with stock option exercises.

As previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018, the Company recognized a deferred tax liability of $7.9 million in the fourth quarter of 2018 related to the Company’s estimate of non-U.S. taxes it will incur when distributing the unremitted earnings of certain foreign subsidiaries. The Company incurred withholding cash tax payments related to the repatriation of a portion of these foreign earnings during the first nine months of 2019 and reduced this deferred tax liability by approximately $3.6 million. The deferred tax liability on unremitted earnings as of September 30, 2019 is $11.7 million, which reflects an increase as a result of recording a $8.1 million deferred tax liability on certain foreign unremitted earnings assumed in connection with the Combination.As of September 30, 2019, the Company’s cumulative liability for gross unrecognized tax benefits was $13.4 million. As of December 31, 2018, the Company’s cumulative liability for gross unrecognized tax benefits was $7.1 million. Pursuant to the Combination, the Company acquired gross unrecognized tax benefits of $9.1 million.

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 Operations. The Company recognized an expense for interest of $0.1 million and $0.4 million for the three and nine months ended September 30, 2019, respectively, and an expense for penalties of less than $0.1 million and $0.1 million for the three and nine months ended September 30, 2019, respectively. Comparatively, the Company recognized an expense of less than $0.1 million and $0.1 million for interest, and a credit of $0.2 million and an expense of $0.1 million for penalties in its Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2018, respectively. As of September 30, 2019, the Company had accrued $1.9 million for cumulative interest and $2.4 million for cumulative penalties in its Condensed Consolidated Balance Sheet, compared to $0.6 million for cumulative interest and $0.8 million for cumulative penalties accrued at December 31, 2018.

During the nine months ended September 30, 2019 and 2018, the Company recognized a decrease of $1.5 million and $0.7 million, respectively, 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, 2019 it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $1.9 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 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, 2019.

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 2006, China from 2009, Canada from 2010, the Netherlands from 2013, Mexico and the United Kingdom from 2014, Spain from 2015, the U.S. and Germany from 2016, India from fiscal year beginning April 1, 2016 and ending March 31, 2017, and various U.S. state tax jurisdictions from 2009.

As a result of the closing of the Combination and subsequent purchase accounting, as described in Note 2 of Notes to Condensed Consolidated Financial Statements, the Company has recorded initial estimates for certain acquired tax assets and liabilities. These initial estimates included: (i) deferred tax liabilities of approximately $187 million related to the fair value step-up for certain intangible assets, property, plant and equipment, and inventory; (ii) deferred tax assets of approximately $38 million related to foreign tax credit carry-forwards, net of applicable valuation allowances related to these foreign tax credit carry-forwards to reflect the forecasted expiration of unutilized credits; (iii) deferred tax liabilities of approximately $8 million related to non-U.S. taxes it will incur when distributing unremitted foreign earnings of certain Houghton subsidiaries; (iv) deferred tax liabilities of approximately $8 million related to the Company’s outside basis difference in its Korean joint venture and (v) as it relates to uncertain tax positions, an approximately $12 million reserve primarily related to the deductibility of expenses at certain Houghton subsidiaries.

As previously reported, the Italian tax authorities have assessed additional tax due from the Company’s subsidiary, Quaker Italia S.r.l., relating to the tax years 2007 through 2013. The Company has filed for competent authority relief from these assessments under the Mutual Agreement Procedures (“MAP”) of the Organization for Economic Co-Operation and Development for all years except 2007. During 2018, the Italian tax authorities assessed additional tax due from Quaker Italia, S.r.l., relating to the tax years 2014 and 2015. The Company met with the Italian tax authorities in the fourth quarter of 2018 and second quarter of 2019 to discuss these assessments and no resolution was agreed upon, so the Company filed for competent authority relief from these assessments under MAP in the second quarter of 2019, consistent with the Company’s previous filings for 2008 through 2013. During the third quarter of 2019, the Italian and Spanish tax authorities proposed a settlement relating to the Company’s competent authority requests for tax years 2007 through 2010. The Company is currently reviewing the settlement proposal and considering its available options. Tax years 2011 through 2015 are still pending competent authority review. As of September 30, 2019, the Company believes it has adequate reserves for uncertain tax positions with respect to these and all other audits.

During the third quarter of 2019, Houghton’s Italian subsidiary received a tax assessment related to the 2014 tax year. In addition, tax years 2015 through 2017 are also under audit. The Company is still assessing the technical merits of the 2014 assessment and, therefore, has not recorded a reserve for this jeopardy tax assessment as of September 30, 2019.

Diluted (loss) earnings per common share		$	(0.80)	$	1.47	$	1.14	$	3.87

The Company’s calculation of (loss) earnings per diluted share attributable to Quaker Chemical Corporation common shareholders for the three and nine months ended September 30, 2019 was impacted by the 4.3 million share issuance in connection with closing the Combination, comprising approximately 24.5% of the common stock of the Company as of September 30, 2019, as well as the variability of its reported earnings. Therefore, the per diluted share result for each of the first three quarters of 2019, as reported on a standalone basis, may not sum to the per diluted share result for the nine months ended September 30, 2019 .Certain stock options and restricted stock units are not included in the diluted (loss) earnings per share calculation because the effect would have been anti-dilutive. All of the Company’s potentially dilutive shares for the three months ended September 30, 2019 are anti-dilutive and not included in the dilutive (loss) earnings per share calculation because of the Company’s net loss for this period. The calculated amount of anti-dilutive shares not included in the diluted (loss) earnings per common share calculation was 1,905 for the three months ended September 30, 2019. There were no anti-dilutive shares for the nine months ended September 30, 2019. Comparatively, the calculated amount of anti-dilutive shares not included in the diluted earnings per share calculation was 718 and 3,480 for the three and nine months ended September 30, 2018, respectively.

Note 13 – Restricted Cash

The Company has restricted cash recorded in other assets related to proceeds from an inactive subsidiary of the Company which previously executed separate settlement and release agreements with two of its insurance carriers for an original total value of $35.0 million. 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 that earned $0.2 million in the nine months ended September 30, 2019 compared to $0.1 in the nine months ended September 30, 2018. The interest was offset by $0.6 million of payments during the nine months ended September 30, 2019 compared to $0.7 million in the nine months ended September 30, 2018. Due to the restricted 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 defense.

The following table provides a reconciliation of cash, cash equivalents and restricted cash as of September 30, 2019 and 2018 and December 31, 2018 and 2017:

Note 14 – Goodwill and Other Intangible Assets

The Company completes its annual impairment test during the fourth quarter of each year, or more frequently if triggering events indicate a possible impairment in one or more of its reporting units. As described in Note 4 of Notes to Condensed Consolidated Financial Statements, during the third quarter of 2019, the Company changed its reportable segments and associated reporting units. In connection with this change, the Company performed a qualitative assessment and concluded that there was no evidence of events or circumstances that would indicate a material change from the Company’s prior year quantitative impairment assessment. The Company has recorded no impairment charges in its past and continually evaluates financial performance, economic conditions and other relevant developments in assessing if an interim period impairment test for one or more of its reporting units is necessary.

In connection with the change in its reportable segments, noted above, the Company reallocated existing goodwill to each of the new reportable segments and associated reporting units, based on management’s estimate of the relative fair value of each reporting unit. The result of this reallocation of goodwill has been recast to the following disclosure of goodwill, by reportable segment, as of December 31, 2018. Changes in the carrying amount of goodwill for the nine months ended September 30, 2019 were as follows:

								Global

The Company recorded $9.2 million and $12.8 million of amortization expense for the three and nine months ended September 30, 2019, respectively. Comparatively, the Company recorded $1.8 million and $5.5 million of amortization expense for the three and nine months ended September 30, 2018, respectively. Estimated annual aggregate amortization expense for the current year and subsequent five years is as follows:

For the year ended December 31, 2019	$	18,261
For the year ended December 31, 2020		51,141

Credit facilities

As previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018, in connection with the Combination, the Company initially secured $1.15 billion in commitments from Bank of America Merrill Lynch and Deutsche Bank to fund the purchase consideration and to provide additional liquidity, which was replaced with a syndicated bank agreement (the “New Credit Facility”) with a group of lenders. Prior to closing the Combination, during July 2019, the Company amended and extended the bank commitment to August 30, 2019. The New Credit Facility was contingent upon and was not effective until the closing of the Combination. Concurrent with the closing of the Combination on August 1, 2019, the New Credit Facility is in full effect and is the Company’s primary borrowing facility, replacing the Company’s previous revolving credit facility (the “Old Credit Facility”).

The New Credit Facility is comprised of a $400.0 million multicurrency revolver (“Revolver”), a $600.0 million U.S. dollar denominated term loan (“U.S. Term Loan”), each with the Company as borrower, and a $150.0 million (euro equivalent) euro denominated term loan (“EURO Term Loan”) with Quaker Chemical B.V., a Dutch subsidiary of the Company as borrower (collectively with the U.S. Term Loan, the “Term Loans”), each with a five-year term maturing in August 2024. The maximum amount available under the New Credit Facility can be increased by $300.0 million at the Company’s option if the lenders agree and the Company has satisfied certain conditions. Borrowings under the New Credit Facility bear interest at a base rate or LIBOR plus an applicable margin based upon the Company’s consolidated net leverage ratio. Interest cost incurred on the outstanding borrowings under the New Credit Facility post-closing of the Combination was approximately 3.3%. In addition to paying interest on outstanding principal under the New Credit Facility, the Company is required to pay a 0.25% commitment fee to the lenders under the Revolver in respect of the unutilized commitments thereunder. The Company has unused capacity under the Revolver of approximately $281 million, net of bank letters of credit of approximately $9 million, as of September 30, 2019. Until closing of the Combination, the Company incurred certain interest costs to maintain the bank commitment (“ticking fees”), which began to accrue on September 29, 2017 and bore an interest rate of 0.30% per annum. Concurrent with closing of the Combination and executing the New Credit Facility, the Company paid approximately $6.3 million of ticking fees.

The New Credit Facility is subject to certain financial and other covenants, including covenants that the Company’s initial consolidated net debt to consolidated adjusted EBITDA ratio cannot exceed 4.25 to 1 and the Company’s consolidated adjusted EBITDA to interest expense ratio cannot be less than 3.0 to 1 (as such covenants are defined therein). At the closing of the Combination and as of September 30, 2019, the Company was in compliance with all of the New Credit Facility covenants. The Term Loans have quarterly principal amortization during their respective five-year maturities, with 5.0% amortization of the principal balance due in years 1 and 2, 7.5% in year 3, and 10.0% in years 4 and 5, with the remaining principal amount due at maturity. The New Credit Facility is guaranteed by certain of the Company’s domestic subsidiaries and is secured by first priority liens on substantially all of the assets of the Company and the domestic subsidiary guarantors, subject to certain customary exclusions, and the obligations of the Dutch borrower only are guaranteed by certain foreign subsidiaries on an unsecured basis.

The New Credit Facility required the Company fix at least 20% of the variable interest rates on its Term Loans. In November 2019, the Company entered into $170.0 million notional amounts of three-year interest rate swaps at a fixed rate of approximately 3.1% to satisfy this requirement of the New Credit Facility as well as to manage the Company’s exposure to variable interest rate risk associated with the New Credit Facility. The Company anticipates that these interest rate swaps will be designated and will qualify as cash flow hedges.

The Company capitalized $23.7 million of certain third-party debt issuance costs in connection with executing the New Credit Facility. Approximately $15.5 million of the capitalized costs was attributed to the Term Loans and was recorded as a direct reduction of long-term debt on the Company’s Condensed Consolidated Balance Sheet. Approximately $8.3 million was attributed to the Revolver and recorded within other assets on the Company’s Condensed Consolidated Balance Sheet. These capitalized costs will be amortized into interest expense over the five-year term of the New Credit Facility. The Old Credit Facility was a $300.0 million syndicated multicurrency, unsecured revolving credit facility with a group of lenders. The maximum amount available under the Old Credit Facility could have been increased to $400.0 million at the Company’s option if the lenders agreed and the Company satisfied certain conditions. Borrowings under the Old Credit Facility generally bore interest at a base rate or LIBOR rate plus a margin. The Old Credit Facility had certain financial and other covenants, with the key financial covenant requiring that the Company’s consolidated total debt to adjusted EBITDA ratio could not exceed 3.50 to 1. At the date the Old Credit Facility was replaced, the Company was in compliance with all of its covenants. During July 2019, the Old Credit Facility was amended and restated to extend the maturity date to August 31, 2020, and was subsequently replaced by the New Credit Facility as of August 1, 2019.

Industrial development bonds

As of September 30, 2019 and December 31, 2018, the Company had fixed rate, industrial development authority bonds due in 2028. These bonds have similar covenants to the credit facilities noted above.

Bank lines of credit and other debt obligations

In connection with the Combination, the Company assumed certain unsecured bank lines of credit and discounting facilities in one of its foreign subsidiaries. The bank lines of credit are not collateralized. Total unused capacity under these arrangements as of September 30, 2019 was approximately $10 million. The Company’s other debt obligations primarily consist of certain domestic and foreign low interest rate or interest-free municipality-related loans, local credit facilities of certain foreign subsidiaries and capital lease obligations.

In addition to the bank letters of credit described in the Credit facilities section above, the Company’s only other off-balance sheet arrangements include financial guarantees. The Company’s total bank letters of credit and guarantees outstanding as of September 30, 2019 were approximately $15 million.

At September 30, 2019, annual maturities on long-term borrowings maturing in the next five fiscal years and thereafter (excluding the reduction to long-term debt attributed to capitalized and unamortized debt issuance costs) are as follows:

2020	$	45,876
2021		35,276
2022		49,556
2023		60,590
2024		676,271

The Company incurred the following debt related expenses included within Interest expense, net, on the Condensed Consolidated Statements of Operations:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2019		2018		2019		2018
Interest expense	$	5,761	$	1,510	$	8,258	$	4,804
Amortization of debt issuance costs		792		—		792		—
Total	$	6,553	$	1,510	$	9,050	$	4,804

Based on the variable interest rates associated the New Credit Facility and Old Credit Facility, as of September 30, 2019 and December 31, 2018, the amounts at which the Company’s total debt were recorded are not materially different from their fair market value.

Note 18 – Commitments and Contingencies

The Company previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018 that AC Products, Inc. (“ACP”), a wholly owned subsidiary, has been operating a groundwater treatment system to hydraulically contain groundwater contamination emanating from ACP’s site, the principal contaminant of which is perchloroethylene. As of September 30, 2019, ACP believes it is close to meeting the conditions for closure of the groundwater treatment system, but continues to operate this system while in discussions with the relevant authorities. As of September 30, 2019, the Company believes that the range of potential-known liabilities associated with the balance of the ACP water remediation program is approximately $0.1 million to $1.0 million. 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 program management.

The Company previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018 that an inactive subsidiary of the 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. During the nine months ended September 30, 2019, there have been no significant changes to the facts or circumstances of this previously disclosed matter, aside from on-going claims and routine payments associated with this litigation. 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 approximately $1.7 million (excluding costs of defense).

As a result of the closing of the Combination on August 1, 2019, the Company is now party to Houghton environmental matters related to certain domestic and foreign properties currently or previously owned, described below. The Company continually evaluates its obligations related to such matters and has estimated the range of costs for all of the Houghton environmental matters to be between approximately $4 million and $5 million as of September 30, 2019, for which $4.8 million is accrued within other current liabilities on the Company’s Condensed Consolidated Balance Sheets as of September 30, 2019.

Houghton’s Sao Paulo, Brazil site was required under Brazilian environmental, health and safety regulations to perform an environmental assessment as a part of a permit renewal process. The site has conducted a multi-year soil and groundwater investigation and corresponding risk assessments based on the result of the investigations. Initial investigations identified soil and ground water contamination in select areas of the site. In 2017, the site had to submit a new 5-year permit renewal request and was asked to complete additional investigations to further delineate the site based on review of the technical data by the local regulatory agency, Companhia Ambiental do Estado de São Paulo (“CETESB”). Based on review of the updated investigation data, CETESB issued a Technical Opinion regarding the investigation and remedial action taken to date. The site developed an action plan and submitted to CETESB in 2018 based on CETESB requirements. The site intervention plan primarily requires the site, amongst other actions, to conduct periodic monitoring for methane in soil vapors, source zone delineation, groundwater plume delineation, bedrock aquifer assessment, update the human health risk assessment, develop a current site conceptual model and conduct a remedial feasibility study and provide a revised intervention plan. In December 2019, the site is required to submit a report on the activities

completed including the revised site conceptual model and results of the remedial feasibility study and recommended remedial strategy for the site.

Other Houghton environmental matters the Company is now party to include participation in certain payments in connection with four currently active environmental consent orders related to certain hazardous waste cleanup activities under the U.S. Federal Superfund statute where Houghton has been designated a potentially responsible party (“PRP”) by the Environmental Protection Agency along with a certain number of other PRPs depending on the site, and other obligations to perform cleanup activities at certain other foreign subsidiaries. These environmental matters primarily require the Company to perform long-term monitoring as well as operating and maintenance at each of the applicable sites.

The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental or other litigation matters, that it has made adequate accruals regarding matters of which it is aware. Approximately $0.2 million was accrued at September 30, 2019 and December 31, 2018, respectively, to provide for such anticipated future environmental assessments, remediation costs and other litigation matters. The Company believes that where it is party to other litigation, it will not have a material adverse effect on the Company’s results of operations, cash flows or financial condition.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis Of Accounting Policy [Policy Text Block]	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 Securities 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 opinion of management, the financial statements reflect all adjustments which are of a normal and recurring nature and are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the three and nine months ended September 30, 2019, respectively, are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K, as amended by the Company’s Form 10-K/A, for the year ended December 31, 2018.
Segment Reporting, Policy [Policy Text Block]	The Company’s reportable segments reflect 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 assesses its performance. During the third quarter of 2019 and in connection with the Combination, the Company reorganized its executive management team to align with its new business structure, which reflects the method by which the Company assesses its performance and allocates its resources. The Company’s new reportable segment structure includes four segments: (i) Americas; (ii) Europe, Middle East and Africa (“EMEA”); (iii) Asia/Pacific; and (iv) Global Specialty Businesses. The three geographic segments are composed of the net sales and operations in each respective region, excluding net sales and operations managed globally by the Global Specialty Businesses segment, which includes the Company’s container, metal finishing, mining, offshore, specialty coatings and specialty grease businesses. All prior period information for legacy Quaker has been recast to reflect these four segments as the Company’s new reportable segments. Prior to the Company’s re-segmentation during the third quarter of 2019, the Company’s historical reportable segments were four geographic regions: (i) North America; (ii) EMEA; (iii) Asia/Pacific; and (iv) South America.
Revenue Recognition [Policy Text Block]	The Company applies the FASB’s guidance on revenue recognition which requires the Company to recognize revenue in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services transferred to its customers. To do this, the Company applies the five-step model in the FASB’s guidance, which requires the Company to: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation.
Revenue From Contract With Customer [Policy Text Block]	As part of the Company’s Fluidcare business, 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, revenue is recognized on a net reporting basis generally at the amount of the administrative fee earned by the Company for ordering the goods.A contract liability is recognized when the Company receives consideration, or if it has the unconditional right to receive consideration, in advance of performance. A contract liability is the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration, or a specified amount of consideration is due, from the customer. The Company’s contract liabilities primarily represent deferred revenue recorded for customer payments received by the Company prior to the Company satisfying the associated performance obligation. Deferred revenues are presented within other current liabilities in the Company’s Condensed Consolidated Balance Sheets.
Goodwill And Intangible Assets, Goodwill, Policy [Policy Text Block]	The Company completes its annual impairment test during the fourth quarter of each year, or more frequently if triggering events indicate a possible impairment in one or more of its reporting units. As described in Note 4 of Notes to Condensed Consolidated Financial Statements, during the third quarter of 2019, the Company changed its reportable segments and associated reporting units. In connection with this change, the Company performed a qualitative assessment and concluded that there was no evidence of events or circumstances that would indicate a material change from the Company’s prior year quantitative impairment assessment.
Lessee Leases [Policy Text Block]	The Company determines if an arrangement is a lease at its inception. This determination generally depends on whether the arrangement conveys the right to control the use of an identified fixed asset explicitly or implicitly for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the rights to direct the use of, and obtains substantially all of the economic benefits from the use of, the underlying asset. Lease expense for variable leases and short-term leases is recognized when the obligation is incurred.
Equity And Cost Method Investments, Policy [Policy Text Block]	Investments in associated companies presented in the table above represents the Company’s initial fair value estimate of its 50% interest in a Houghton joint venture in Korea. The Company accounts for this interest under the equity method of accounting.

Business Combination Separately Recognized Transactions [Line Items]
Business Combination Separately Recognized Transactions Description			On August 1, 2019, the Company completed the Combination with Houghton, whereby the Company acquired all of the issued and outstanding shares of Houghton from Gulf Houghton Lubricants, Ltd. and certain other selling shareholders in exchange for a combination of cash and shares of the Company’s common stock in accordance with the share purchase agreement dated April 4, 2017. Houghton is a leading global provider of specialty chemicals and technical services for metalworking and other industrial applications. Combining Quaker and Houghton’s product and service offerings will allow Quaker Houghton to better serve its customers in its various end markets. The Combination was subject to certain regulatory and shareholder approvals. At a shareholder meeting held during 2017, the Company’s shareholders approved the issuance of new shares of the Company’s common stock at closing of the Combination. Also in 2017, the Company received regulatory approvals for the Combination from China and Australia. The Company received regulatory approvals from the European Commission (“EC”) during the second quarter of 2019 and the U.S. Federal Trade Commission (“FTC”) in July 2019. The approvals from the FTC and the EC required the concurrent divestiture of certain steel and aluminum related product lines of Houghton, which were sold by Houghton on August 1, 2019 for approximately $37 million in cash. The final remedy agreed with the EC and the FTC was consistent with the Company’s previous expectation that the total divested product lines would be approximately 3% of the combined company’s net sales.

Restructuring And Related Cost Description	The QH Program will include restructuring and associated severance costs to reduce total headcount by approximately 275 people globally and plans for the closure of certain manufacturing and non-manufacturing facilities. The exact timing and total costs associated with the QH Program will depend on a number of factors and is subject to change, however, the Company currently expects reduction in headcount and site closures to occur over the next two years under the QH Program and estimates that total costs related to the QH Program will approximate one-time the anticipated cost synergies realized. Employee separation benefits will vary depending on local regulations within certain foreign countries and will include severance and other benefits.

Defined Benefit Plan, Expected Contributions In Current Fiscal Year					$ 6,000
Defined Benefit Plan, Contributions by Employer			$ 4,000
Defined benefit plan description of nature of event resulting in contractual termination benefits to be recognized in future period			The Company previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018 that the Company began the process of terminating Quaker’s primary non-contributory U.S. pension plan (the “U.S. Pension Plan”) during the fourth quarter of 2018. As part of this process, and considering the fully funded status of the U.S. Pension Plan, the asset allocation of the U.S. Pension Plan was adjusted modeling a glide path that is more heavily allocated to fixed income securities with lengthened durations to match the projected liabilities. As a result, the expected return on plan assets declined during the three and nine months ended September 30, 2019 compared to the three and nine months ended September 30, 2018. In order to terminate the U.S. Pension Plan in accordance with Internal Revenue Service (“I.R.S.”) and Pension Benefit Guaranty Corporation requirements, the Company will be required to fully fund the U.S. Pension Plan on a termination basis and will commit to contribute additional assets if necessary, to do so. The amount necessary to do so is not yet known but is currently estimated to be between $0 and $10 million. In addition, the Company expects to record a non-cash pension settlement charge at plan termination. This settlement charge will include the immediate recognition into expense of the related unrecognized losses within AOCI on the balance sheet as of the plan termination date. The Company does not have a current estimate for this future settlement charge, however, the gross AOCI related to the U.S. Pension Plan was approximately $18.5 million as of September 30, 2019. During the third quarter of 2019, the Company received a favorable termination determination letter from the I.R.S. and has amended the Plan to comply with final regulations of the Internal Revenue Code. The Company currently estimates that the U.S. Pension Plan termination will be completed during 2020.
Multi employer Plans Business Combination Or Divestiture Description			In connection with the Combination, the Company now contributes to a multiemployer defined benefit pension plan under terms of a collective bargaining union contract (the Cleveland Bakers and Teamsters Pension Fund). The expiration date of the collective bargaining contract is May 1, 2022. As of January 1, 2018, the last valuation date available for the multiemployer plan, total plan liabilities were approximately $592 million. As of December 31, 2018, the multiemployer pension plan had total plan assets of approximately $315 million. The Company’s contribution rate to the multiemployer pension plan is specified in the collectivebargaining union contract and contributions are made to the plan based on its union employee payroll. The Company contributed less than $0.1 million during the three and nine months ended September 30, 2019. While the Company may also have additional liabilities imposed by law as a result of its participation in the multiemployer defined benefit pension plan, there is no liability as of September 30, 2019. The Employee Retirement Income Security Act of 1974, as amended by the Multi-Employer Pension Plan Amendments Act of 1980, imposes certain contingent liabilities upon an employer who is a contributor to a multiemployer pension plan if the employer withdraws from the plan or the plan is terminated or experiences a mass withdrawal.

Other Information Pertaining To Income Taxes			As a result of the closing of the Combination and subsequent purchase accounting, as described in Note 2 of Notes to Condensed Consolidated Financial Statements, the Company has recorded initial estimates for certain acquired tax assets and liabilities. These initial estimates included: (i) deferred tax liabilities of approximately $187 million related to the fair value step-up for certain intangible assets, property, plant and equipment, and inventory; (ii) deferred tax assets of approximately $38 million related to foreign tax credit carry-forwards, net of applicable valuation allowances related to these foreign tax credit carry-forwards to reflect the forecasted expiration of unutilized credits; (iii) deferred tax liabilities of approximately $8 million related to non-U.S. taxes it will incur when distributing unremitted foreign earnings of certain Houghton subsidiaries; (iv) deferred tax liabilities of approximately $8 million related to the Company’s outside basis difference in its Korean joint venture and (v) as it relates to uncertain tax positions, an approximately $12 million reserve primarily related to the deductibility of expenses at certain Houghton subsidiaries.
U.S. Tax Reform			As previously disclosed in its Annual Report filed on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2018, the Company recognized a deferred tax liability of $7.9 million in the fourth quarter of 2018 related to the Company’s estimate of non-U.S. taxes it will incur when distributing the unremitted earnings of certain foreign subsidiaries. The Company incurred withholding cash tax payments related to the repatriation of a portion of these foreign earnings during the first nine months of 2019 and reduced this deferred tax liability by approximately $3.6 million. The deferred tax liability on unremitted earnings as of September 30, 2019 is $11.7 million, which reflects an increase as a result of recording a $8.1 million deferred tax liability on certain foreign unremitted earnings assumed in connection with the Combination.

Earnings Per Share Reconciliation Disclosure			The Company’s calculation of (loss) earnings per diluted share attributable to Quaker Chemical Corporation common shareholders for the three and nine months ended September 30, 2019 was impacted by the 4.3 million share issuance in connection with closing the Combination, comprising approximately 24.5% of the common stock of the Company as of September 30, 2019, as well as the variability of its reported earnings. Therefore, the per diluted share result for each of the first three quarters of 2019, as reported on a standalone basis, may not sum to the per diluted share result for the nine months ended September 30, 2019 .

Loss Contingency, Settlement Agreement, Terms	The Company has restricted cash recorded in other assets related to proceeds from an inactive subsidiary of the Company which previously executed separate settlement and release agreements with two of its insurance carriers for an original total value of $35.0 million. 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 that earned $0.2 million in the nine months ended September 30, 2019 compared to $0.1 in the nine months ended September 30, 2018. The interest was offset by $0.6 million of payments during the nine months ended September 30, 2019 compared to $0.7 million in the nine months ended September 30, 2018. Due to the restricted 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 defense

Line of Credit Facility Current Borrowing Capacity	$ 1,150,000
Line of Credit Facility, Covenant Terms	The New Credit Facility is subject to certain financial and other covenants, including covenants that the Company’s initial consolidated net debt to consolidated adjusted EBITDA ratio cannot exceed 4.25 to 1 and the Company’s consolidated adjusted EBITDA to interest expense ratio cannot be less than 3.0 to 1 (as such covenants are defined therein). At the closing of the Combination and as of September 30, 2019, the Company was in compliance with all of the New Credit Facility covenants. The Term Loans have quarterly principal amortization during their respective five-year maturities, with 5.0% amortization of the principal balance due in years 1 and 2, 7.5% in year 3, and 10.0% in years 4 and 5, with the remaining principal amount due at maturity.
Line of Credit Facility, Amount Outstanding	$ 110,000	$ 24,034
Bank lines of credit and other debt obligations	$ 10,846	$ 2,570
Line Of Credit Facility Initiation Date 1	Aug. 01, 2019
Line Of Credit Facility Interest Rate Description	Borrowings under the New Credit Facility bear interest at a base rate or LIBOR plus an applicable margin based upon the Company’s consolidated net leverage ratio. Interest cost incurred on the outstanding borrowings under the New Credit Facility post-closing of the Combination was approximately 3.3%. In addition to paying interest on outstanding principal under the New Credit Facility, the Company is required to pay a 0.25% commitment fee to the lenders under the Revolver in respect of the unutilized commitments thereunder.
Line of Credit Remaining borrowing Capacity, net of letters of credit	The Company has unused capacity under the Revolver of approximately $281 million, net of bank letters of credit of approximately $9 million, as of September 30, 2019.
Debt Issuance Cost Capitalization	The Company capitalized $23.7 million of certain third-party debt issuance costs in connection with executing the New Credit Facility. Approximately $15.5 million of the capitalized costs was attributed to the Term Loans and was recorded as a direct reduction of long-term debt on the Company’s Condensed Consolidated Balance Sheet. Approximately $8.3 million was attributed to the Revolver and recorded within other assets on the Company’s Condensed Consolidated Balance Sheet. These capitalized costs will be amortized into interest expense over the five-year term of the New Credit Facility.
Line Of Credit Facility Initiation Date Description	Prior to closing the Combination, during July 2019, the Company amended and extended the bank commitment to August 30, 2019. The New Credit Facility was contingent upon and was not effective until the closing of the Combination. Concurrent with the closing of the Combination on August 1, 2019, the New Credit Facility is in full effect and is the Company’s primary borrowing facility, replacing the Company’s previous revolving credit facility (the “Old Credit Facility”).
Other off balance sheet arrangements	In addition to the bank letters of credit described in the Credit facilities section above, the Company’s only other off-balance sheet arrangements include financial guarantees. The Company’s total bank letters of credit and guarantees outstanding as of September 30, 2019 were approximately $15 million.
Description Of Types Of Fair Value Hedging Instruments Used	The New Credit Facility required the Company fix at least 20% of the variable interest rates on its Term Loans. In November 2019, the Company entered into $170.0 million notional amounts of three-year interest rate swaps at a fixed rate of approximately 3.1% to satisfy this requirement of the New Credit Facility as well as to manage the Company’s exposure to variable interest rate risk associated with the New Credit Facility. The Company anticipates that these interest rate swaps will be designated and will qualify as cash flow hedges.

Loss Contingency Actions Taken By Defendant	Houghton’s Sao Paulo, Brazil site was required under Brazilian environmental, health and safety regulations to perform an environmental assessment as a part of a permit renewal process. The site has conducted a multi-year soil and groundwater investigation and corresponding risk assessments based on the result of the investigations. Initial investigations identified soil and ground water contamination in select areas of the site. In 2017, the site had to submit a new 5-year permit renewal request and was asked to complete additional investigations to further delineate the site based on review of the technical data by the local regulatory agency, Companhia Ambiental do Estado de São Paulo (“CETESB”). Based on review of the updated investigation data, CETESB issued a Technical Opinion regarding the investigation and remedial action taken to date. The site developed an action plan and submitted to CETESB in 2018 based on CETESB requirements. The site intervention plan primarily requires the site, amongst other actions, to conduct periodic monitoring for methane in soil vapors, source zone delineation, groundwater plume delineation, bedrock aquifer assessment, update the human health risk assessment, develop a current site conceptual model and conduct a remedial feasibility study and provide a revised intervention plan. In December 2019, the site is required to submit a report on the activitiescompleted including the revised site conceptual model and results of the remedial feasibility study and recommended remedial strategy for the site.
