EXPLANATORY NOTE



This Amendment No. 1 on Form 10-K/A
(this “Amended Filing”) amends our original Annual Report on Form 10-K for the year ended December 31, 2018 filed with
the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2019 (the “Original Filing”). However,
this amendment does not change our consolidated financial statements as set forth in the Original Filing.



The purpose of this Amended Filing is to
(i) revise the “Report of Independent Registered Certified Public Accounting Firm” of PricewaterhouseCoopers LLP
appearing in the Index to Consolidated Financial Statements regarding the effectiveness of our internal control over financial
reporting and (ii) revise the disclosure on our internal control over financial reporting in Part II, Item 9A to
reflect management’s conclusion that our disclosure controls and procedures were not effective at December 31, 2018 due to
a material weakness in our internal control over financial reporting identified subsequent to the issuance of our Original Filing.
This material weakness did not result in any change to our consolidated financial statements as set forth in the Original Filing.
Part IV, Item 15, “Exhibits and Financial Statement Schedules,” also has been amended to include currently dated certifications
from the Company’s Chief Executive Officer and Chief Financial Officer as required by sections 302 and 906 of the Sarbanes
Oxley Act of 2002. The certifications are attached to this Amended Filing as Exhibits 31.1, 31.2, 32.1 and 32.2.



Other than the inclusion within this Amended
Filing of new certifications by management and a new consent of our independent registered certified public accounting firm (and
related amendment to the exhibit index that is incorporated by reference into Item 15 of the Original Filing to reflect the
addition of such certifications and consent and related changes to the footnotes to that exhibit index), this Amended Filing speaks
only as of the date of the Original Filing and does not modify or update any other disclosures contained in our Original Filing.
Specifically, there are no changes to our consolidated financial statements set forth in the Original Filing. This Amended Filing
should be read in conjunction with the Original Filing and reports filed with the SEC subsequent to the Original Filing.

Report of Independent Registered Public
Accounting Firm



To the Shareholders and Board of Directors of Quaker Chemical
Corporation



Opinions on the Financial Statements and Internal Control
over Financial Reporting



We have audited the accompanying consolidated balance sheets
of Quaker Chemical Corporation and its subsidiaries (the “Company”) as of December 31, 2018 and 2017 and the related
consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period
ended December 31, 2018, including the related notes (collectively referred to as the “consolidated financial statements”).
We also have audited the Company's internal control over financial reporting as of December 31, 2018, based on criteria established
in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO).



In our opinion, the consolidated financial statements referred
to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017,and
the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018 in conformity
with accounting principles generally accepted in the United States of America. Also in our opinion, the Company did not maintain,
in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established
in Internal Control - Integrated Framework (2013) issued by the COSO because a material weakness in internal control over
financial reporting existed as of that date related to the design and maintenance of controls over certain aspects of the Company’s
information technology.



A material weakness is a deficiency, or a combination of deficiencies,
in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual
or interim financial statements will not be prevented or detected on a timely basis. The material weakness referred to above is
described in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. We considered
this material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the 2018 consolidated
financial statements, and our opinion regarding the effectiveness of the Company’s internal control over financial reporting
does not affect our opinion on those consolidated financial statements.



Restatement of Management’s Conclusion Regarding Internal
Control over Financial Reporting



Management and we previously concluded that the Company maintained
effective internal control over financial reporting as of December 31, 2018. However, management has subsequently determined that
a material weakness in internal control over financial reporting related to certain aspects of its controls over information technology
existed as of that date. Accordingly, management’s report has been restated and our present opinion on internal control over
financial reporting, as presented herein, is different from that expressed in our previous report.



Basis for Opinions



The Company's management is responsible for these consolidated
financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness
of internal control over financial reporting, included in management's report referred to above. Our responsibility is to express
opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting
based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States)
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.





2







We conducted our audits in accordance with the standards of
the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over
financial reporting was maintained in all material respects.



Our audits of the consolidated financial statements included
performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error
or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated
financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered
necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.



Definition and Limitations of Internal Control over Financial
Reporting



A company’s internal control over financial reporting
is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations
of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.



Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject
to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies
or procedures may deteriorate.

February 28, 2019, except with respect to our opinion on internal
control over financial reporting insofar as it relates to the effects of the matter described in the penultimate paragraph of Management’s Report on Internal Control over Financial Reporting, as to which the date is July 24, 2019



We have served as the Company’s auditor since at least
1972. We have not been able to determine the specific year we began serving as auditor of the Company.

QUAKER CHEMICAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except share and
per share amounts, unless otherwise stated)



Note 1 – Significant Accounting Policies



Principles of consolidation:All
majority-owned subsidiaries are included in the Company’s consolidated financial statements, with appropriate elimination
of intercompany balances and transactions.  Investments in associated companies (less than majority-owned and in which the
Company has significant influence) are accounted for under the equity method.  The Company’s share of net income or
losses in these investments in associated companies is included in the Consolidated Statements of Income.  The Company periodically
reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline
in market value or other impairment indicators are deemed to be other than temporary.  See Note 16 of Notes to Consolidated
Financial Statements.  The Company is not the primary beneficiary of any variable interest entities (“VIEs”) and
therefore the Company’s consolidated financial statements do not include the accounts of any VIEs.



Translation of foreign currency:Assets
and liabilities of non-U.S. subsidiaries and associated companies are translated into U.S. dollars at the respective rates of exchange
prevailing at the end of the year.  Income and expense accounts are translated at average exchange rates prevailing during
the year.  Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive
(loss) income (“AOCI”) and will be included as income or expense only upon sale or liquidation of the underlying entity
or asset.  Generally, all of the Company’s non-U.S. subsidiaries use their local currency as their functional currency.



Cash and cash equivalents:The Company
invests temporary and excess funds in money market securities and financial instruments having maturities within 90 days. 
The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.  The
Company has not experienced losses from the aforementioned investments.



Inventories:Inventories are valued
at the lower of cost or net realizable value, and are valued using the first-in, first-out method.  See Note 13 of Notes to
Consolidated Financial Statements.



Long-lived assets:Property, plant
and equipment are stated at cost.  Depreciation is computed using the straight-line method on an individual asset basis over
the following estimated useful lives: buildings and improvements, 10 to 45 years; and machinery and equipment, 1 to 15 years. 
The carrying values of long-lived assets are evaluated whenever changes in circumstances or current events indicate the carrying
amount of such assets may not be recoverable.  An estimate of undiscounted cash flows produced by the asset, or the appropriate
group of assets, is compared with the carrying value to determine whether an impairment exists.  If necessary, the Company
recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. 
Fair value is based on current and anticipated future cash flows.  Upon sale or other dispositions of long-lived assets, the
applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from
disposals, is recorded in the Consolidated Statements of Income.  Expenditures for renewals or improvements that increase
the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenance are expensed
when incurred.  See Notes 8 and 14 of Notes to Consolidated Financial Statements.



Capitalized software:The Company
capitalizes certain costs in connection with developing or obtaining software for internal use, depending on the associated project.
 These costs are amortized over a period of 3 to 5 years once the assets are ready for their intended use.  In connection
with the implementations and upgrades to the Company’s global transaction, consolidation and other related systems, approximately
$1.1 million and $1.3 million of net costs were capitalized in property, plant and equipment on the Company’s December 31,
2018 and 2017 Consolidated Balance Sheets, respectively.



Goodwill and other intangible assets:The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at the
date of acquisition.  Goodwill and indefinite-lived intangible assets are not amortized but tested for impairment at least
annually.  These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived
intangible assets are amortized over their estimated useful lives, generally for periods ranging from 4 to 20 years.  The
Company continually evaluates the reasonableness of the useful lives of these assets, consistent with the discussion of long-lived
assets, above.  See Note 15 of Notes to Consolidated Financial Statements.





9







Revenue recognition:During the
first quarter of 2018, the Company adopted the provisions of the Financial Accounting Standards Board’s (“FASB’s”)
revenue recognition guidance which required the Company to recognize revenue to depict the transfer of promised goods or services
to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods
or services.  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 adopted the new revenue recognition guidance electing to use a modified
retrospective adoption approach applied to those contracts which were not completed as of January 1, 2018.  Therefore, comparative
information has not been restated and continues to be accounted for and reported under the historical revenue recognition accounting
standards in effect for those periods.  Prior to this adoption, the Company recognized revenue in accordance with the terms
of the underlying agreements, when title and risk of loss had been transferred, when collectability was reasonably assured, and
when pricing was fixed or determinable.  This generally occurred when products were shipped or delivered to customers or,
for consignment-type arrangements, upon usage by the customer and when services were performed.  See Notes 3 and 4 of Notes
to Consolidated Financial Statements.



Accounts receivable and allowance for
doubtful accounts:Trade accounts receivable subject the Company to credit risk.  Trade accounts receivable are recorded
at the invoiced amount and generally do not bear interest.  The allowance for doubtful accounts is the Company’s best
estimate of the amount of probable credit losses with its existing accounts receivable.  Reserves for customers filing for
bankruptcy protection are established based on a percentage of the amount outstanding at the bankruptcy filing date.  However,
initially establishing a reserve and the amount thereto is dependent on the Company’s evaluation of likely proceeds to be
received from the bankruptcy process, which could result in the Company recognizing minimal or no reserve at the date of bankruptcy. 
Large and/or financially distressed customers are generally reserved for on a specific review basis while a general reserve is
established for other customers based on historical experience.  The Company performs a formal review of its allowance for
doubtful accounts quarterly.  Account balances are charged off against the allowance when the Company deems it is probable
the receivable will not be recovered.  The Company does not have any off-balance-sheet credit exposure related to its customers.
 See Notes 4 and 12 of Notes to Consolidated Financial Statements.



Research and development costs:
Research and development costs are expensed as incurred and are included in selling, general and administrative expenses (“SG&A”). 
Research and development expenses were $24.5 million, $23.9 million and $22.5 million for the years ended December 31, 2018, 2017
and 2016, respectively.



Environmental liabilities and expenditures:
Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability
can be reasonably estimated.  If there is a range of estimated liability and no amount in that range is considered more probable
than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles
in the United States (“U.S. GAAP”).  Accrued liabilities are exclusive of claims against third parties and are
not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or
improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or prevent contamination in
the future.  See Note 25 of Notes to Consolidated Financial Statements.



Asset retirement obligations:The
Company follows the FASB’s guidance regarding asset retirement obligations, which addresses the accounting and reporting
for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs.  Also, the
Company follows the FASB’s guidance for conditional asset retirement obligations (“CARO”), which relates to legal
obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future
event that may or may not be within the control of the entity.  In accordance with this guidance, the Company records a liability
when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis. 
 As of December 31, 2018 and 2017, the Company had limited exposure to such obligations and had immaterial liabilities recorded
for such on its Consolidated Balance Sheets.



Pension and other postretirement benefits:The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering a portion of
its employees in the U.S. and certain other countries.  The plans of the Company’s subsidiaries in the Netherlands,
the United Kingdom, Mexico and Sweden are subject to the provisions of FASB’s guidance regarding employers’ accounting
for defined benefit pension plans.  The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully
insured or integrated with the local governments’ plans and are not subject to the provisions of the guidance.  The
guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other
postretirement plans on their consolidated balance sheet and, also, recognize as a component of AOCI, net of tax, the gains or
losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit
cost.  In addition, the guidance requires that an employer recognize a settlement charge in their consolidated statement of
income when certain events occur, including plan termination or the settlement of certain plan liabilities.  A settlement
charge represents the immediate recognition into expense of a portion of the unrecognized loss within AOCI on the balance sheet
in proportion to the share of the projected benefit obligation that was settled.  The Company’s U.S. pension plan year
ends on November 30 and the measurement date is December 31.  The measurement date for the Company’s other postretirement
benefits plan is December 31.





10







The Company’s global pension investment
policies are designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations
of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security
Act of 1974.  The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant
asset classes with the aim of achieving a prudent balance between return and risk.



The Company’s investment horizon
is generally long term, and, accordingly, the target asset allocations encompass a long-term perspective of capital markets, expected
risk and return and perceived future economic conditions while also considering the profile of plan liabilities.  To the extent
feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration
is immunized to reduce the risk of volatility in intermediate plan distributions, and the total return portfolio is expected to
maximize the long-term real growth of plan assets.  The critical investment principles of diversification, assessment of risk
and targeting the optimal expected returns for given levels of risk are applied.  The Company’s investment guidelines
prohibit the use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short
sales, margin transactions, private placements (unless specifically addressed by addendum), or any derivatives, options or futures
for the purpose of portfolio leveraging.



The target asset allocation is reviewed
periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields,
returns, volatilities and correlation relationships.  The interaction between plan assets and benefit obligations is periodically
studied to assist in establishing such strategic asset allocation targets.  Asset performance is monitored with an overall
expectation that plan assets will meet or exceed benchmark performance over rolling five-year periods.  The Company’s
pension committee, as authorized by the Company’s Board of Directors, has discretion to manage the assets within established
asset allocation ranges approved by senior management of the Company.  As of December 31, 2018, the plan’s investments
were in compliance with all approved ranges of asset allocations.  See Note 20 of Notes to Consolidated Financial Statements.



Comprehensive income (loss): The
Company presents other comprehensive income (loss) in its Statements of Comprehensive Income.  The Company follows the FASB’s
guidance regarding the disclosure of reclassifications from AOCI which requires the disclosure of significant amounts reclassified
from each component of AOCI, the related tax amounts and the income statement line items affected by such reclassifications. 
See Note 22 of Notes to Consolidated Financial Statements.



Income taxes and uncertain tax positions:
The provision for income taxes is determined using the asset and liability approach of accounting for income taxes.  Under
this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities
are recovered or paid.  The provision for income taxes represents income taxes paid or payable for the current year and the
change in deferred taxes during the year.  Deferred taxes result from differences between the financial and tax bases of the
Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.  Valuation
allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. 
The FASB’s guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement
attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. 
The guidance further requires the determination of whether the benefits of tax positions are probable or more likely than not sustained
upon audit based upon the technical merits of the tax position.  For tax positions that are determined to be more likely than
not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized
upon ultimate settlement in the financial statements.  For tax positions that are not determined to be more likely than not
sustained upon audit, a company does not recognize any portion of the benefit in the financial statements.  Additionally,
the Company monitors and adjusts for derecognition, classification, and penalties and interest in interim periods, with appropriate
disclosure and transition thereto.  Also, the amount of interest expense and income related to uncertain tax positions is
computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including
timing differences, and the amount previously taken or expected to be taken in a tax return.  The Company’s continuing
practice is to recognize interest and/or penalties related to income tax matters in income tax expense.  Finally, when applicable,
the Company nets its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other
tax credit carryforwards that would apply if the uncertain tax position were settled for the presumed amount at the balance sheet
date.





11







Pursuant to the Tax Cuts and Jobs Act (“U.S.
Tax Reform”), specifically the one-time tax on deemed repatriation (the “Transition Tax”), the Company has provided
for U.S. income tax on its undistributed earnings of non-U.S. subsidiaries, however, the Company is subject to and will incur other
taxes, such as withholding taxes and dividend distribution taxes, if these undistributed earnings were ultimately remitted to the
U.S.  It is the Company’s current intention to reinvest its future undistributed earnings of non-U.S. subsidiaries to
support working capital needs and certain other growth initiatives.  However, in certain cases the Company has and may in
the future change its indefinite reinvestment assertion for any or all of these undistributed earnings.  In this case, the
Company would estimate and record a tax liability and corresponding tax expense for the amount of non-U.S. income taxes it will
incur to ultimately remit these earnings to the U.S.  See Note 9 of Notes to Consolidated Financial Statements.



Derivatives: The Company is exposed
to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk.  The
Company is currently not using derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes
in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to
fluctuations in interest rates in the past.  If used in the future, the Company will recognize the entire change in the fair
value of the hedging instrument in the same income statement line as the hedged item.  The Company currently uses no derivative
instruments designated as hedges and, also, has not entered into derivative contracts for trading or speculative purposes.



Fair value measurements:The Company
utilizes the FASB’s guidance regarding fair value measurements, which establishes a common definition for fair value to be
applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about
such fair value measurements.  Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation
techniques used to measure fair value into three broad levels.  See Notes 20 and 24 of Notes to Consolidated Financial Statements. 
The following is a brief description of those three levels:



| | • | Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.                                                                                                                                                                                     
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | • | Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.  These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
| | • | Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.                                                                                                                                                                                                                        



Share-based compensation:The Company
applies the FASB’s guidance regarding share-based payments, which requires the recognition of the fair value of share-based
compensation as a component of expense.  The Company has a long-term incentive program (“LTIP”) for key employees
which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant.
 Most options become exercisable between one and three years after the date of the grant for a period of time determined by
the Company, but not to exceed seven years from the date of grant.  Restricted stock awards and restricted stock units issued
under the LTIP program are generally subject to time vesting over a one to four-year period.  In addition, as part of the
Company’s Global Annual Incentive Plan, nonvested shares may be issued to key employees, which generally vest over a two
to five-year period.  In addition, while the FASB’s guidance permits the Company to make an accounting policy election
to account for forfeitures as they occur for service condition aspects of certain share-based awards, the Company has decided not
to elect this accounting policy and instead has elected to continue utilizing a forfeiture rate assumption.  Based on historical
experience, the Company has assumed a forfeiture rate of 13% on certain of its nonvested stock awards.  The Company will record
additional expense if the actual forfeiture rate is lower than estimated and will record a recovery of prior expense if the actual
forfeiture is higher than estimated.  See Note 7 of Notes to Consolidated Financial Statements.





12







Earnings per share:The Company
follows the FASB’s guidance regarding the calculation of earnings per share for nonvested stock awards with rights to non-forfeitable
dividends.  The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of
the basic weighted average share calculation under the two-class method.  See Note 10 of Notes to Consolidated Financial Statements.



Segments:  The Company’s
operating 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.  The Company’s operating segments
are organized by geography as follows: (i) North America, (ii) Europe, Middle East and Africa (“EMEA”), (iii) Asia/Pacific
and (iv) South America.  The Company’s reportable segments are the same as the Company’s operating segments. 
See Note 5 of Notes to Consolidated Financial Statements.



Hyper-inflationary accounting:Economies
that have a cumulative three-year rate of inflation exceeding 100 percent are considered hyper-inflationary in accordance with
U.S. GAAP.  A legal entity which 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 Consolidated Statements of Income.



Venezuela’s economy has been considered
hyper-inflationary under U.S. GAAP since 2010.  The Company has a 50-50 joint venture in a Venezuelan affiliate, Kelko Quaker
Chemical, S.A (“Kelko Venezuela”).  Due to heightened foreign exchange controls, current economic circumstances
and other restrictions in 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 December 31, 2018, the Company has no remaining carrying value for its investment in Kelko Venezuela. 
See Note 16 of Notes to Consolidated Financial Statements.



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 Argentina subsidiary beginning July 1, 2018.  As of, and for the year ended December
31, 2018, the Company's Argentina subsidiary represented less than 1% of the Company’s consolidated total assets and less
than 1% of the Company’s consolidated net sales.  During the years ended December 31, 2018, 2017 and 2016, the Company
recorded $0.7 million, $0.4 million, and $0.1 million, respectively, of hyper-inflationary accounting remeasurement losses associated
with the applicable currency conversions related to Venezuela and Argentina.



Business combinations:The Company
accounts for business combinations under the acquisition method of accounting.  This method requires the recording of acquired
assets, including separately identifiable intangible assets and assumed liabilities at their respective acquisition date estimated
fair values.  Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded
as goodwill.  The determination of the estimated fair value of assets acquired and liabilities assumed requires significant
estimates and assumptions.  Based on the assessment of additional information during the measurement period, which may be
up to one year from the acquisition date, the Company may record adjustments to the estimated fair value of assets acquired and
liabilities assumed.  See Note 23 of Notes to Consolidated Financial Statements.



Restructuring activities: Restructuring
programs consist of employee severance, rationalization of manufacturing or other facilities and other related items.  To
account for such programs, the Company applies FASB’s guidance regarding exit or disposal cost obligations.  This guidance
requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred,
is estimable, and payment is probable.  See Note 6 of Notes to Consolidated Financial Statements.



Reclassifications: Certain information
has been reclassified to conform to the current year presentation.  During the first quarter of 2018, the Company adopted
guidance regarding the accounting for and disclosure of net sales and revenue recognition.  The Company’s adoption,
using the modified retrospective adoption approach, resulted in certain adjustments as of January 1, 2018.  In addition, during
the first quarter of 2018, the Company adopted an accounting standard update requiring that the statement of cash flows explain
both the change in total cash and cash equivalents and also the amounts generally described as restricted cash or restricted cash
equivalents.  The guidance in this accounting standard update was required to be applied retrospectively which resulted in
certain adjustments to the Company’s Consolidated Statement of Cash Flows for the year ended December 31, 2017 and 2016. 
See Notes 3, 4 and 11 of Notes to Consolidated Financial Statements.



Accounting estimates: The preparation
of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets, liabilities and disclosure of contingencies at the date of the financial statements
and the reported amounts of net sales and expenses during the reporting period.  Actual results could differ from such estimates.

Note 2 – Houghton Combination



In April 2017, Quaker entered into a share
purchase agreement with Gulf Houghton Lubricants, Ltd. to purchase the entire issued and outstanding share capital of Houghton
International, Inc. (“Houghton”) (herein referred to as “the Combination”).  The shares will be bought
for aggregate purchase consideration consisting of: (i) $172.5 million in cash; (ii) a number of shares of common stock, $1.00
par value per share, of the Company comprising 24.5% of the common stock outstanding upon the closing of the Combination; and (iii)
the Company’s assumption of Houghton’s net indebtedness as of the closing of the Combination, which was approximately
$690 million at signing.  At closing, the total aggregate purchase consideration is dependent on the Company’s stock
price and the level of Houghton’s indebtedness.



The Company secured $1.15 billion in commitments
from Bank of America Merrill Lynch and Deutsche Bank to fund the Combination and to provide additional liquidity, and has since
replaced these commitments with a syndicated bank agreement (“the New Credit Facility”) with a group of lenders for
$1.15 billion.  The New Credit Facility is contingent upon and will not be effective until the closing of the Combination. 
During the fourth quarter of 2018, the Company extended the bank commitment for the New Credit Facility through March 15, 2019. 
The New Credit Facility is comprised of a $400.0 million multicurrency revolver, a $600.0 million USD term loan and a $150.0 million
EUR equivalent term loan, each with a five-year term from the date the New Credit Facility becomes effective.  The maximum
amount available under the New Credit Facility can be increased by $200.0 million at the Company’s option if the lenders
agree and the Company satisfies certain conditions.  Borrowings under the New Credit Facility will bear interest at a base
rate, LIBOR rate plus a margin, or Euribor rate plus a margin.  The Company currently estimates the annual floating rate cost
will be in the 3.75% to 4.0% range based on current market interest rates.  The New Credit Facility will be subject to certain
financial and other covenants, including covenants that the Company’s consolidated net debt to 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. 
Both the USD and EUR equivalent term loans will have quarterly principal amortization during their respective five-year terms,
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 amounts due at maturity.  Until closing, the Company will incur certain interest costs paid to maintain the bank
commitment (“ticking fees”), which began to accrue on September 29, 2017 and bear an interest rate of 0.30% per annum.



The Company received regulatory approval
for the Combination from China and Australia in 2017.  In addition, at a shareholder meeting held during 2017, the Company’s
shareholders overwhelmingly approved the issuance of the new shares of the Company’s common stock at closing of the Combination. 
The European Commission (“EC”) conditionally approved the Combination in December 2018, including the remedy proposed
by Quaker and Houghton.  The Company expects final approval from the EC once the final purchase agreement is in place between
Quaker, Houghton, and the buyer of the divested product lines.  The Company continues to be in productive discussions with
the U.S. Federal Trade Commission (“FTC”), although the process is taking longer than anticipated.  Given the
time lapse since the Company’s initial filing, the FTC requested updated information as part of their approval process late
in the fourth quarter of 2018.  In addition, the government shutdown in the U.S. during the first quarter of 2019 extended
the timeline to receive the final approval.  Given current information, the Company estimates that FTC and EC final approval
and closing of the combination will occur within the next few months.



The Company incurred costs of $19.5 million,
$30.8 million and $1.5 million during the years ended December 31, 2018, 2017 and 2016, respectively, primarily for certain legal,
environmental, financial, and other advisory and consultant costs related to due diligence, regulatory and shareholder approvals,
integration planning associated with the Combination and ticking fees.  As of December 31, 2018 and 2017, the Company had
current liabilities related to the Combination of $8.2 million and $5.5 million, respectively, primarily recorded within other
current liabilities on its Consolidated Balance Sheets.

Note 3 – Recently Issued Accounting Standards



The FASB issued an accounting standard
update in October 2018 to provide guidance on the risks associated with financial assets and liabilities that are permitted to
be hedged.  The amendments in this update permit use of the Overnight Index Swap (“OIS”) rate based on the Secured
Overnight Financing Rate (SOFR) as a U.S. benchmark interest rate in addition to the other four rates: interest rates on direct
Treasury obligations of the U.S. government (UST), the London Interbank Offered Rate (LIBOR) swap rate, the OIS rate based on the
Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. The amendments
in this update also apply to all entities that elect to apply hedge accounting to benchmark interest rate hedges.  The guidance
within this accounting standard update is effective for fiscal years beginning after December 15, 2018, and interim periods within
those fiscal years.  The amendments in this update should be adopted on a prospective basis for qualifying new or re-designated
hedging relationships entered into on or after the date of adoption.  Early adoption is permitted.  The Company has elected
to early adopt the guidance in this accounting standard update during the fourth quarter of 2018, with no impact to its financial
statements.  The Company does not currently use any derivative instruments designated as hedges but may choose to in the future.



The 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 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 should
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 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 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 should be applied prospectively in the
initial year of adoption or prospectively 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 June 2018 to simplify the accounting for share-based payment transactions with non-employees of the Company.  The
guidance within this accounting standard update generally requires that share-based payment transactions for acquiring goods or
services from non-employees of the Company be accounted for under the same guidance and model as all other share-based payment
transactions, including employees of the Company.  The guidance within this accounting standard update is effective for annual
and interim periods beginning after December 15, 2018.  Early adoption is permitted.  The Company elected to early adopt
the guidance within this accounting standard updated in the second quarter of 2018 with no impact to its financial statements.



The FASB issued an accounting standard
update in February 2018 that allows a reclassification from AOCI to retained earnings for stranded tax effects resulting from 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 should 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
is permitted.  The Company has not early adopted the guidance and is currently evaluating its implementation.

The FASB issued an accounting standard
update in January 2017 to clarify the definition of a business with the objective of adding guidance to assist companies with evaluating
whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.  The amendments in this
accounting standard update provided a more robust framework to use in determining when a set of assets and activities is a business. 
The guidance within this accounting standard update was effective for annual and interim periods beginning after December 15, 2017. 
Early adoption was permitted in limited circumstances, and the amendments in this accounting standard update were required to be
applied prospectively, with no disclosures required at transition.  The Company adopted the guidance in the first quarter
of 2018, as required, with no impact to its financial statements.



The FASB issued an accounting standard
update in November 2016 requiring that the statement of cash flows explain both the change in the total cash and cash equivalents,
and also the amounts generally described as restricted cash or restricted cash equivalents.  This required amounts generally
described as restricted cash or restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning
and ending amounts shown on the statement of cash flows.  The guidance within this accounting standard update was effective
for annual and interim periods beginning after December 15, 2017.  Early adoption was permitted, and the guidance required
application using a retrospective transition method to each period presented when adopted.  The Company adopted the guidance
in the first quarter of 2018, as required.  Adoption of the guidance did not have an impact on the Company’s earnings
or balance sheet but did result in changes to certain disclosures within the statement of cash flows, including cash flows from
investing activities and total cash, cash equivalents and restricted cash.  See Note 11 of Notes to Consolidated Financial
Statements.



The FASB issued an accounting standard
update in October 2016 to improve the accounting for the income tax consequences of intra-entity transfers of assets other than
inventory.  The provisions in this update allowed an entity to recognize current and deferred income taxes of an intra-entity
transfer of an asset other than inventory when the transfer occurs rather than when the asset has been sold to an outside party. 
The guidance within this accounting standard update was effective for annual and interim periods beginning after December 15, 2017. 
Early adoption was permitted, and the guidance required application on a modified retrospective basis through a cumulative-effect
adjustment directly to retained earnings as of the beginning of the period of adoption.  The Company adopted the guidance
in the first quarter of 2018, as required, with no impact to its financial statements.



The FASB issued an accounting standard
update in August 2016 to standardize how certain transactions are classified in the statement of cash flows.  Specific transactions
covered by the accounting standard update include debt prepayment or debt extinguishment costs, settlement of zero-coupon debt
instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims,
proceeds from the settlement of corporate and bank owned life insurance policies, distributions received from equity method investments
and beneficial interest in securitization transactions.  The guidance within this accounting standard update was effective
for annual and interim periods beginning after December 15, 2017.  Early adoption was permitted, provided that all of the
amendments were adopted in the same period.  The guidance required application using a retrospective transition method. 
The Company adopted the guidance in the first quarter of 2018 as required, with no impact to its financial statements.



The FASB issued an accounting standard
update in February 2016 regarding the accounting and disclosure for leases.  During 2018, 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 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 are effective for annual and interim periods beginning after December 15, 2018, and should be 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 is permitted,
but the Company has not early adopted.  The Company will adopt the guidance in the first quarter of 2019, as required, using
a modified retrospective transition approach.  The Company will apply the transition requirements in the period of adoption
(as of January 1, 2019), as permitted.  As such the Company will neither restate comparative periods for the effects of this
lease accounting guidance or provide the disclosures requirements for comparative periods.  The Company anticipates electing
to apply certain of the permitted practical expedients within the new lease accounting guidance, and the Company also anticipates
making certain accounting policy elections as a result of adopting the new lease accounting guidance.





16







As of December 31, 2018, the Company has
substantially completed its implementation planning and its impact assessment related to the new lease accounting guidance. 
Work performed to date includes developing a detailed project plan, identifying and establishing a cross-functional implementation
team and developing pre-adoption internal controls.  In addition, the Company gathered an inventory of the Company’s
explicit outstanding leases globally, performed certain review procedures to ensure completeness of its lease population and abstracted
critical lease information from the lease population for inclusion within the Company’s leasing software.  Also, the
Company has begun preliminary considerations for how the new lease accounting guidance may impact Houghton, as it pertains to the
potential Combination.  The Company has calculated a preliminary transition adjustment which will be finalized and reflected
in the Company’s financial statements starting after the effective date of January 1, 2019.  While the Company’s
implementation of this lease accounting guidance is still on-going, the Company anticipates adoption of this guidance will have
a material impact on its balance sheet as it expects the majority of its leases will be recorded on its balance sheet by establishing
right of use assets and associated lease liabilities.  Based on all current available information, the Company estimates that
its right of use assets and associated lease liabilities will be approximately $20 million to $30 million as of January 1, 2019.



The FASB issued an accounting standard
update in May 2014 regarding the accounting for and disclosure of revenue recognition.  Specifically, the update outlined
a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, which will be
common to both U.S. GAAP and International Financial Reporting Standards.  The guidance was effective for annual and interim
periods beginning after December 15, 2016, and allowed for full retrospective adoption of prior period data or a modified retrospective
adoption.  Early adoption was not permitted.  In August 2015, the FASB issued an accounting standard update to delay
the effective date of the new revenue standard by one year, or, in other words, to be effective for annual and interim periods
beginning after December 15, 2017.  Entities were permitted to adopt the new revenue standard early but not before the original
effective date.  During 2016 and 2017, the FASB issued a series of accounting standard updates to clarify and expand on the
implementation guidance, including principal versus agent considerations, identification of performance obligations, licensing,
other technical corrections and adding certain practical expedients.  The amendments in these 2016 and 2017 updates did not
change the core principles of the guidance previously issued in May 2014.



As part of the Company’s impact assessment
for the implementation of the new revenue recognition guidance, the Company reviewed its historical accounting policies and practices
to identify potential differences with the requirements of the new revenue recognition standard as it related to the Company’s
contracts and sales arrangements.  In addition, the impact assessment and work performed included global and cross functional
interviews and questionnaires, sales agreement and other sales document reviews, as well as technical considerations for the Company’s
future transactional accounting, financial reporting and disclosure requirements.  The Company has also progressed its assessment
of how the new revenue recognition guidance may impact Houghton, as it pertains to the pending Combination.



The Company adopted the guidance in the
first quarter of 2018 as required, electing to use a modified retrospective adoption approach applied to those contracts which
were not completed as of January 1, 2018.  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
practical expedients within the revenue recognition guidance and make certain accounting policy elections including those related
to significant financing components, sales taxes and shipping and handling activities.  Adoption of the revenue recognition
guidance did not have a material impact on the Company’s reported earnings or cash flows, however, adoption did increase
the amount and level of disclosures concerning the Company’s net sales and did result in one adjustment to the Company’s
balance sheet.  As a result of the Company’s impact assessment and adoption using the modified retrospective adoption
approach, the Company recorded a cumulative effect of an accounting change as of January 1, 2018 to adjust the Company’s
estimate of variable consideration relating to customers’ expected rights to return product.  This adjustment resulted
in an increase to other current liabilities of $1.0 million, an increase to non-current deferred tax assets of $0.2 million and
a decrease to retained earnings of $0.8 million.  There were no other impacts recorded as a result of adopting the revenue
recognition guidance in 2018 or prior years and the Company expects the impact to be immaterial on an ongoing basis.  See
Note 4 and 18 of Notes to Consolidated Financial Statements.

Note 4 – 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 (“CMS”) for various
heavy industrial and manufacturing applications in a global portfolio throughout its four regions: North America, EMEA, Asia/Pacific
and South America.  The major product lines in the Company’s global portfolio include: (i) rolling lubricants (used
by manufacturers of steel in the hot and cold rolling of steel and by manufacturers of aluminum in the hot rolling of aluminum);
(ii) machining and grinding compounds (used by metalworking customers in cutting, shaping, and grinding metal parts which require
special treatment to enable them to tolerate the manufacturing process, achieve closer tolerance, and improve tool life); (iii)
corrosion preventives (used by steel and metalworking customers to protect metal during manufacture, storage, and shipment); (iv)
hydraulic fluids (used by steel, metalworking, and other customers to operate hydraulic equipment); (v) specialty greases (used
in automotive and aerospace production processes and applications, the manufacturing of steel, and various other applications);
and (vi) metal finishing compounds (used to prepare metal surfaces for special treatments such as galvanizing and tin plating and
to prepare metal for further processing).



A substantial portion of the Company’s
sales worldwide are made directly through its own employees and its CMS 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 of
similar size as well as companies larger and smaller than Quaker.  The offerings of many of the Company’s competitors
differ from those of Quaker; 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 CMS, 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 generally recognized on a net reporting basis 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 fulfilling the promise 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 resulting in net reporting of $47.1 million, $44.5 million and $43.5 million
for the years ended December 31, 2018, 2017 and 2016.



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 other metalworking customers and generally use higher volumes
of products at a single location.  During the year ended December 31, 2018, the Company’s five largest customers accounted
for approximately 17% of its consolidated net sales with the largest customer accounting for approximately 8% of the Company’s
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 is both the sales agreement as well as
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 which
have an initial term of one year or less as permitted by the FASB.





18







The Company identifies a performance obligation
in a contract for each promised good or service that is separately identifiable from other promises 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 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 a promised 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 CMS 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 CMS 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 expense, net, in its Consolidated Statement of Income, 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 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 to not adjust the promised amount of consideration for the effects of a significant financing
component as 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.





19







Contract Assets and Liabilities



The Company recognizes a contract asset
or receivable on its 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 contract assets recorded
on its Consolidated Balance Sheets as of December 31, 2018 or 2017.



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
Consolidated Balance Sheets.  The Company had approximately $1.3 million and $1.5 million of deferred revenue as of December
31, 2018 and 2017, respectively.  During the year ended December 31, 2018, the Company satisfied all of the associated performance
obligations and recognized into revenue the advance customer payments received and recorded as of December 31, 2017.



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 geography first, and then by customer industry, rather than by individual product lines.
 Also, net sales of each of the Company’s major product lines are generally spread throughout all four of the Company’s
regions, and, in most cases, are relatively proportionate to the level of total sales in each region.



The following tables present disaggregated
information regarding the Company’s net sales, first by product lines that represent approximately 10% of consolidated net
sales for any of the years ended December 31, 2018, 2017 and 2016, and followed then by a disaggregation of the Company’s
net sales by region, customer industry, and timing of revenue recognized for the year ended December 31, 2018.

Note 5 – Business Segments



The Company’s reportable operating
segments are organized by geography as follows: (i) North America, (ii) EMEA, (iii) Asia/Pacific and (iv) South America. 
Operating earnings, excluding indirect operating expenses, for the Company’s reportable operating segments is comprised of
revenues less cost of goods sold (“COGS”) and SG&A directly related to the respective region’s product sales. 
The indirect operating expenses consist of SG&A not directly attributable to the product sales of each respective reportable
operating segment.  Other items not specifically identified with the Company’s reportable operating segments include
interest expense, interest income, license fees from non-consolidated affiliates, amortization expense and other expense, net.



The following tables present information

Note 6 – Restructuring and Related Activities



In response to weak economic conditions
and market declines in many regions, Quaker’s management approved a global restructuring plan (the “2015 Program”)
in the fourth quarter of 2015 to reduce its operating costs.  The 2015 Program included provisions for the reduction of total
headcount by approximately 65 employees globally.  The Company substantially completed all of the initiatives under the 2015
Program in 2016 and settlement of these charges occurred primarily in 2016 as well.  During the fourth quarter of 2016, the
Company recognized a restructuring credit of $0.4 million in connection with the 2015 Program, due to customary and routine adjustments
to initial estimates for employee separation costs.  The Company completed all of the remaining initiatives under the 2015
Program during the first half of 2017 and does not expect to incur further restructuring charges under this program.



There were no accrued restructuring liabilities
as of December 31, 2017 and no associated cash payments or other restructuring activity during the year ended December 31, 2018. 
Restructuring activity recognized in each reportable operating segment in connection with the 2015 Program during the years ended

 Intrinsic value is calculated as the difference between the current market price of the underlying security and the strike
price of a related option.

As of December 31, 2018, unrecognized compensation
expense related to options granted in 2018, 2017 and 2016 was $0.8 million, $0.4 million and less than $0.1 million, respectively,
to be recognized over a weighted average period of 1.8 years.



The Company granted stock options under
its LTIP plan that are subject only to time vesting over a three-year period in the first quarters of 2018, 2017, 2016 and 2015.
 For the purposes of determining the fair value of stock option awards, the Company uses the Black-Scholes option pricing
model and the assumptions set forth in the table below:



|                                |  | 2018 |        |   | 2017 |  |        | 2016 |  |  | 2015   |

Employee Stock Purchase Plan



In 2000, the Board adopted an Employee
Stock Purchase Plan (“ESPP”) whereby employees may purchase Company stock through a payroll deduction plan.  Purchases
are made from the plan and credited to each participant’s account at the end of each month (the “Investment Date”).
 The purchase price of the stock is 85% of the fair market value on the Investment Date.  The plan is compensatory, and
the 15% discount is expensed on the Investment Date.  All employees, including officers, are eligible to participate in this
plan.  A participant may withdraw all uninvested payment balances credited to a participant’s account at any time.  An
employee whose stock ownership of the Company exceeds five percent of the outstanding common stock is not eligible to participate
in this plan.



2013 Director Stock Ownership Plan



In 2013, the Company adopted the 2013 Director
Stock Ownership Plan (the “Plan”), to encourage the Directors to increase their investment in the Company, which was
approved at the Company’s May 2013 shareholders’ meeting.  The Plan authorizes the issuance of up to 75,000 shares
of Quaker common stock in accordance with the terms of the Plan in payment of all or a portion of the annual cash retainer payable
to each of the Company’s non-employee directors in 2013 and subsequent years during the term of the Plan.  Under the
Plan, each director who, on May 1 of the applicable calendar year, owns less than 400% of the annual cash retainer
for the applicable calendar year, divided by the average of the closing price of a share of Quaker Common Stock as reported by
the composite tape of the New York Stock Exchange for the previous calendar year (the “Threshold Amount”), is required
to receive 75% of the annual cash retainer in Quaker common stock and 25% of the retainer in cash, unless the director elects to
receive a greater percentage of Quaker common stock, up to 100% of the annual cash retainer for the applicable year.  Each
director who owns more than the Threshold Amount may elect to receive common stock in payment of a percentage (up to 100%) of the
annual cash retainer.  The annual retainer is $0.1 million and the retainer payment date is June 1.

Note 9 – Taxes on Income



On December 22, 2017, the U.S. government
enacted comprehensive tax legislation commonly referred to as U.S. Tax Reform.  U.S. Tax Reform included multiple changes
to the U.S. tax code with varying effects on the Company’s 2017 results, including, but not limited to, (i) a revaluation
of the Company’s U.S. deferred tax assets and liabilities based upon the reduction of the U.S. federal statutory corporate
income tax rate from 35% to 21% and (ii) implementation of a new system of taxation for non-U.S. earnings which eliminates U.S.
federal income taxes on dividends from certain foreign subsidiaries and imposes a one-time transition tax on the deemed repatriation
of undistributed earnings of certain foreign subsidiaries that is payable over eight years.  U.S. Tax Reform also made changes
to the U.S. tax code that have impacted 2018 and will impact future years, including, but not limited to, (i) reduction of the
U.S. federal statutory corporate tax rate; (ii) elimination of the corporate alternative minimum tax; (iii) the creation of the
base erosion anti-abuse tax, a new minimum tax; (iv) a general elimination of U.S. federal income taxes on dividends from foreign
subsidiaries; (v) a new provision designed to tax global intangible low-taxed income (“GILTI”), which allows for the
possibility of using foreign tax credits and a deduction of up to 50 percent to offset the income tax liability (subject to some
limitations); (vi) a new limitation on deductible interest expense; (vii) the repeal of the U.S. production activity deduction;
(viii) limitations on the deductibility of certain executive compensation; (ix) limitations on the use of foreign tax credits to
reduce the U.S. income tax liability; (x) a reduction in the dividends received deduction from 70% to 50% (in the case of less-than-20%-owned
subsidiaries) and from 80% to 65% (in the case of less-than-80%-owned subsidiaries); and (xi) limitations on net operating losses
generated after December 31, 2017 to 80 percent of taxable income.



Also, in 2017, the Securities and Exchange
Commission issued guidance on accounting for the tax effects of U.S. Tax Reform and provided a one-year measurement period for
companies to complete the accounting.  The Company’s initial analysis of the impact of U.S. Tax Reform resulted in an
incremental tax expense of $22.2 million recorded during the fourth quarter of 2017.  U.S. Tax Reform reduced the U.S. federal
statutory corporate tax rate from 35% to 21% effective January 1, 2018.  Consequently, the Company recorded a decrease in
U.S. net deferred tax assets of approximately $4.5 million with a corresponding net adjustment to deferred income tax expense during
the fourth quarter of 2017.  This initial estimate was not adjusted during 2018.  The Transition Tax is a tax on previously
untaxed accumulated and current earnings and profits of certain of the Company’s foreign subsidiaries as of either the November
2, 2017 or December 31, 2017 measurement date provided within U.S. Tax Reform.  The Company made a reasonable estimate of
its Transition Tax and recorded a gross provisional Transition Tax obligation during the fourth quarter of 2017 of $18.4 million,
or $17.8 million, net of the impact of eliminating U.S. Federal income taxes on dividends from certain foreign subsidiaries received
during 2017.

Subsequent to numerous temporary regulations,
notices, and other formal guidance published by the Internal Revenue Service (“IRS”), U.S. Treasury, and various state
taxing authorities in 2018, the Company completed its accounting for the tax effects of U.S. Tax Reform as of December 22, 2018
and refined the total incremental tax expense related to U.S. Tax Reform to approximately $28.0 million.  Based on proposed
regulations published by the U.S. federal and state taxing authorities, the Company recorded a $2.5 million tax benefit to adjust
its net Transition Tax to $15.3 million.  The Company elected to pay its Transition Tax in installments over eight years as
provided for in U.S. Tax Reform.  In addition, the Company recorded deferred income tax expense of $0.3 million in 2018 related
to the deductibility of certain executive compensation based on formal guidance issued by the IRS in 2018.  As a result of
the impacts from U.S. Tax Reform, the Company re-evaluated its global cash strategy resulting in a change to its indefinite reinvestment
assertion attributable to a portion of its undistributed foreign earnings and recognized a deferred tax liability and corresponding
deferred tax expense of $7.9 million, which primarily represents the Company’s estimate of the non-U.S. income taxes the
Company will incur to ultimately remit those earnings to the U.S.   The Company’s reinvestment assertions are further
explained below.

As of December 31, 2018, the Company had
a net deferred tax liability of $2.0 million in the U.S.  In addition, the Company has foreign tax loss carryforwards of $6.6
million of which none will expire through 2023, and $0.6 million expires thereafter.  The remaining foreign tax losses have
no expiration dates.  A partial valuation allowance has been established with respect to the tax benefit of these losses for
$0.4 million.



Pursuant to U.S. Tax Reform, specifically
the Transition Tax, the Company has recorded a charge for U.S. income taxes on its undistributed earnings of non-U.S. subsidiaries;
however, the Company could be subject to other taxes, such as withholding taxes and dividend distribution taxes if these undistributed
earnings are ultimately remitted to the U.S.  As a result of the impacts from U.S. Tax reform, the Company re-evaluated its
global cash strategy, resulting in a change to its indefinite reinvestment assertion attributable to a portion of its undistributed
foreign earnings, and recognized a deferred tax liability and corresponding deferred tax expense of $7.9 million as of December
31, 2018, which primarily represents the Company’s estimate of the non-U.S. taxes the Company will incur to ultimately remit
these earnings to the U.S.  It is the Company’s current intention to reinvest its additional undistributed earnings
of non-U.S. subsidiaries to support working capital needs and certain other growth initiatives.  The amount of such undistributed
earnings at December 31, 2018 was approximately $210.0 million.  Any tax liability which might result from ultimate remittance
of these earnings is expected to be substantially offset by foreign tax credits (subject to certain limitations).  It is currently
impractical to estimate any such incremental tax expense.



As of December 31, 2018, the Company’s
cumulative liability for gross unrecognized tax benefits was $7.1 million. The Company had accrued approximately $0.8 million for
cumulative penalties and $0.6 million for cumulative interest as of December 31, 2018.  As of December 31, 2017, the Company’s
cumulative liability for gross unrecognized tax benefits was $6.8 million. The Company had accrued approximately $1.0 million for
cumulative penalties and $0.6 million for cumulative interest as of December 31, 2017.



The Company continues to recognize interest
and penalties associated with uncertain tax positions as a component of tax expense on income before equity in net income of associated
companies in its Consolidated Statements of Income.  The Company recognized a credit of $0.2 million for penalties and an
expense of $0.1 million for interest (net of expirations and settlements) in its Consolidated Statement of Income for the year
ended December 31, 2018, a credit of $0.7 million for penalties and a credit of $0.2 million for interest (net of expirations and
settlements) in its Consolidated Statement of Income for the year ended December 31, 2017, and a credit of $0.2 million for penalties
and a credit of $0.7 million for interest (net of expirations and settlements) in its Consolidated Statement of Income for the
year ended December 31, 2016.



The Company estimates that during the year
ending December 31, 2019, it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $0.9 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.  A reconciliation of the beginning and ending amounts of unrecognized tax benefits
for the years ended December 31, 2018, 2017 and 2016, respectively, is as follows:



|                                                                             |  | 2018 |        |   | 2017 |   |        | 2016 |

|Decrease in unrecognized tax benefits taken in prior periods                 |  |      | (183   | ) |      |   | (308   | )    | 
|Increase in unrecognized tax benefits taken in current period                |  |      | 2,023  |   |      |   | 2,347  |      | 
|Decrease in unrecognized tax benefits due to lapse of statute of limitations |  |      | (1,292 | ) |      |   | (2,116 | )    | 
|(Decrease) increase due to foreign exchange rates                            |  |      | (259   | ) |      |   | 598    |      | 
|Unrecognized tax benefits as of December 31                                  |  | $    | 7,050  |   |      | $ | 6,761  |      | 



The amount of unrecognized tax benefits
above that, if recognized, would impact the Company’s tax expense and effective tax rate is $2.2 million, $2.2 million and
$1.8 million for the years ended December 31, 2018, 2017 and 2016, respectively.



The Company and its subsidiaries are subject
to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions.  Tax years that remain
subject to examination by major tax jurisdictions include Brazil from 2000, Italy from 2007, the Netherlands from 2012, the United
Kingdom and Mexico from 2013, Spain and China from 2014, India from fiscal year beginning April 1, 2016 and ending March 31, 2017,
the U.S. from 2015, and various U.S. state tax jurisdictions from 2009.

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 the second
quarter of 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 to discuss these assessments and
no resolution was agreed upon, so the Company filed an appeal with the first level of tax court in Italy. If the appeal is not
successful in materially reducing the assessed tax, then the Company will further evaluate its options including potentially filing
for competent authority relief from these assessments under MAP, consistent with the Company’s previous filings for 2008
through 2013. As of December 31, 2018, the Company believes it has adequate reserves for uncertain tax positions with respect to
these and all other audits.

Certain stock options and restricted stock
units are not included in the diluted earnings per share calculation since the effect would have been anti-dilutive.  The
calculated amount of anti-diluted shares not included were 1,808 in 2018, 3,671 in 2017 and 678 in 2016.



Note 11 – 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 which earned $0.2 million and less than $0.1 million in the years ended December
31, 2018 and 2017, respectively, offset by $1.1 million and $0.8 million of net payments in 2018 and 2017, respectively. 
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.  See also Notes 17, 21 and 25 of Notes to Consolidated Financial
Statements.



The following table provides a reconciliation
of cash, cash equivalents and restricted cash as December 31, 2018, 2017, 2016 and 2015:

a 50% investment in and had significant influence over Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical, S.A. (Panama)
and held a 33% investment in and had significant influence over Primex, Ltd. (Barbados).  The carrying amount of the Company’s

$6.2 million in Nippon Quaker Chemical, Ltd. (Japan); and $0.4 million in Kelko Quaker Chemical, S.A. (Panama).



The Company has a 50-50 joint venture in
a Venezuelan affiliate, Kelko Venezuela.  Due to heightened foreign exchange controls, current economic circumstances and
other restrictions in 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 December 31, 2018, the Company has no remaining carrying value for its investment in Kelko Venezuela.

Credit facilities



The Company’s primary credit facility
(“the Credit Facility”) is a $300.0 million syndicated multicurrency credit agreement with a group of lenders. 
The maximum amount available under the Credit Facility can be increased to $400.0 million at the Company’s option if the
lenders agree and the Company satisfies certain conditions.  Borrowings under the Credit Facility generally bear interest
at a base rate or LIBOR rate plus a margin.  The Credit Facility has certain financial and other covenants, with the key financial
covenant requiring that the Company’s consolidated total debt to adjusted EBITDA ratio cannot exceed 3.50 to 1.  As
of December 31, 2018 and 2017, the Company’s consolidated total debt to adjusted EBITDA ratio was below 1.0 to 1, and the
Company was also in compliance with all of its other covenants.  During the fourth quarter of 2018, the Credit Facility was
amended and restated to extend the maturity date to March 15, 2020.  As of December 31, 2018 and 2017, the Company had total
credit facility borrowings of $24.0 million and $48.5 million, primarily under the Credit Facility, at weighted average borrowing
rates of 1.00% and 1.88%, respectively.



Industrial development bonds



As of December 31, 2018 and 2017, the Company
had a fixed rate, industrial development authority bond for $10.0 million due in 2028 and bearing interest at a rate of 5.26%. 
As of December 31, 2017, the Company also had a $5.0 million industrial development authority bond bearing interest at a rate of
5.60%, which matured and was paid off during the fourth quarter of 2018.  These bonds have similar covenants to the Credit
Facility, noted above.



Municipality-related loans



As part of a past expansion project at
the Company’s Middletown, Ohio facility, it agreed to a low interest rate $3.5 million loan with the Ohio Department of Development. 
Principal repayment on this loan began in September 2010 with its final maturity being in February 2021.  The current interest
rate of 2% will rise to 3% beginning March 2019 until final maturity.  As of December 31, 2018 and 2017, there was $0.8 million
and $1.1 million, respectively, outstanding on this loan.



The Company’s Verkol S.A.U. (“Verkol”)
subsidiary has certain loans issued by the local government which are either interest-free or bear interest at a subsidized rate. 
These loans mature periodically, with the last maturity occurring in 2028.  The Company records these loans at fair value
based on market interest rates on the date of acquisition and continues to measure the loans at amortized cost, recognizing the
implicit interest incurred.  As of December 31, 2018 and 2017, there was $1.8 million and $2.2 million, respectively, outstanding
for these loans.



34











During the next five years, payments on
the Company’s debt are due as follows:



|2019 |  |  | $ | 670    | 
|---- |  |  | - | ------ | 
|2020 |  |  |   | 24,730 |

|2023 |  |  |   | 240    |

at which the Company’s debt is recorded are not materially different from their fair market value.

The long-term rates of return on assets
were selected from within the reasonable range of rates determined by (a) historical real returns for the asset classes covered
by the investment policy and (b) projections of inflation over the long-term period during which benefits are payable to plan participants.

Plan Assets and Fair Value





The Company’s pension plan target
asset allocation and the weighted-average asset allocations as of December 31, 2018 and 2017 by asset category were as follows:



|Asset Category              |  | Target |     |   | 2018 |  |     | 2017 | 
|--------------------------- |  | ------ | --- | - | ---- |  | --- | ---- |

|Foreign Plans               |  |        |     |   |      |  |     |      |

|Total                       |  |        | 100 | % |      |  | 100 | %    | 



During the year ended December 31, 2018,
the Company elected to adjust its U.S. Plans’ asset allocation along a glide path based on the funded status of the U.S.
Plan.  As funded status improved, the assets were allocated more heavily to debt securities with lengthened duration to match
projected liability movements.



As of December 31, 2018 and 2017, “Other”
consisted principally of cash and cash equivalents (approximately 1% of plan assets in each respective period).



The following is a description of the valuation
methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant
to the valuation hierarchy, where applicable:



Cash and Cash Equivalents



Cash and cash equivalents consist
of cash and money market funds and are classified as Level 1 investments.



Common Stock



Common stock is valued based
on quoted market prices on an exchange in an active market and is classified as Level 1 investments.





39









Commingled Funds



Investments in the U.S. pension
plan and foreign pension plan commingled funds represent pooled institutional investments, including primarily collective investment
trusts.  These commingled funds are not available on an exchange or in an active market and these investments are valued using
their net asset value (“NAV”), which is generally based on the underlying asset values of the pooled investments held
in the trusts.



As of December 31, 2018, the
U.S. pension plan commingled funds included approximately 10 percent of investments in equity securities and 90 percent of investments
in fixed income securities.  As of December 31, 2018, foreign pension plan commingled funds included approximately 30 percent
of investments in equity securities, 60 percent of investments in fixed income securities, and 10 percent of other non-related
investments, primarily real estate.



Pooled Separate Accounts



Investments in the U.S. pension
plan pooled separate accounts consist of insurance annuity contracts and are valued based on the reported unit value at year end. 
Units of the pooled separate account are not traded on an exchange or in an active market and these investments are valued using
their NAV.



Insurance Contract



Investments in the foreign pension
plan insurance contract are valued at the highest value available for the Company at year end, either the reported cash surrender
value of the contract or the vested benefit obligation.  Both the cash surrender value and the vested benefit obligation are
determined based on unobservable inputs, which are contractually or actuarially determined, regarding returns, fees, the present
value of the future cash flows of the contract and benefit obligations.  The contract is classified as a Level 3 investment.



Diversified Equity Securities
- Registered Investment Companies



Investments in the foreign pension
plans diversified equity securities of registered investment companies are based upon the quoted redemption value of shares in
the fund owned by the plan at year end.  The shares of the fund are not available on an exchange or in an active market; however,
the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market and are
classified as Level 2 investments.



Fixed Income – Foreign
Registered Investment Companies



Investments in the foreign pension
plans fixed income securities of foreign registered investment companies are based upon the quoted redemption value of shares in
the fund owned by the plan at year end.  The shares of the fund are not available on an exchange or in an active market; however,
the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market and are
classified as Level 2 investments.



Real Estate



The foreign pension plan’s
investment in real estate consists of an investment in a property fund.  The fund’s underlying investments consist of
real property, which are valued using unobservable inputs.  The property fund is classified as a Level 3 investment.



As of December 31, 2018 and 2017, the U.S.
and foreign plans’ investments measured at fair value on a recurring basis were as follows:

U.S. pension assets include Company common
stock in the amount of $1.5 million (3% of total U.S. plan assets) as of December 31, 2017.  There was no Company common stock
held in U.S. pension assets as of December 31, 2018.



During the second quarter of 2017, the
Company’s primary noncontributory U.S. pension plan (the “U.S. Pension Plan”) offered a cash settlement to its
vested terminated participants, which allowed them to receive the value of their pension benefits as a single lump sum payment. 
As payments from the U.S. Pension Plan for this cash out offering exceeded the service and interest cost components of the U.S.
Pension Plan expense for the year ended December 31, 2017, the Company recorded a settlement charge of approximately $1.9 million. 
This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within AOCI on
the balance sheet in proportion to the share of the projected benefit obligation that was settled by these payments.  The
gross pension benefit obligation was reduced by approximately $4.0 million as a result of these payments.  The settlement
charge was recognized through other expense, net, on the Company’s Consolidated Statements of Income.



In the fourth quarter of 2018, the Company
began the process of terminating the U.S. Pension Plan after receiving Board of Director approval to do so.  Prior to December
31, 2005, the U.S. Pension Plan covered substantially all employees of the Company’s U.S. subsidiary who had at least one
year of eligible service and had attained age 21.  Effective December 31, 2005, the U.S. Pension Plan was amended to freeze
benefit accruals with respect to participants who were not part of a collective bargaining unit and effective after November 30,
2013, the U.S. Pension Plan was further amended to freeze benefit accruals for the remaining members of a collective bargaining
unit.  U.S. Pension Plan participants will have their benefits either converted into a lump sum cash payment or an annuity
contract placed with an insurance carrier.  The U.S. Pension Plan is fully-funded on a U.S. GAAP basis.  In order to
terminate the plan in accordance with IRS and pension benefit guaranty corporation requirements, the Company will be required to
fully fund the plan on a termination basis and will commit to contribute the additional assets necessary, if any, 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 pension settlement charge at plan termination.  This settlement charge will include the immediate
recognition into expense of the 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 this plan was approximately
$19 million as of December 31, 2018.  The Company currently estimates that the U.S. Pension Plan termination will be completed
during 2020.



Cash Flows



Contributions



The Company expects to make minimum cash
contributions of approximately $5.2 million to its pension plans (approximately $0.5 million U.S. and $4.7 million Foreign) and
approximately $0.4 million to its other postretirement benefit plan in 2019.



Estimated Future Benefit Payments



Excluding any impact related to the U.S.
Pension Plan termination process noted above, the following benefit payments, which reflect expected future service, as appropriate,
are expected to be paid:

The Company maintains a plan under which
supplemental retirement benefits are provided to certain officers.  Benefits payable under the plan are based on a combination
of years of service and existing postretirement benefits.  Included in total pension costs are charges of $1.6 million, $1.4
million and $0.9 million for the years ended December 31, 2018, 2017 and 2016, respectively, representing the annual accrued benefits
under this plan.

Defined Contribution Plan



The Company has a 401(k) plan with an employer
match covering a majority of its U.S. employees.  The plan allows for and the Company previously paid a nonelective contribution
on behalf of participants who have completed one year of service equal to 3% of the eligible participants’ compensation in
the form of Company common stock.  During the first quarter of 2017, the Company began matching both non-elective and elective
401(k) contributions in cash, rather than stock.  Total Company contributions were $3.1 million, $2.9 million and $2.7 million
for the years ended December 31, 2018, 2017 and 2016, respectively.

Note 22 – Equity and Accumulated Other Comprehensive
Loss



In May 2015, the Company’s Board
of Directors authorized a share repurchase program for the repurchase of up to $100.0 million of Quaker Chemical Corporation common
stock (the “2015 Share Repurchase Program”).  The 2015 Share Repurchase Program has no expiration date. 
The 2015 Share Repurchase Program provides a framework of conditions under which management can repurchase shares of the Company’s
common stock.  These purchases may be made in the open market or in private and negotiated transactions and will be in accordance
with applicable laws, rules and regulations.



In connection with the 2015 Share Repurchase
Program, the Company acquired 83,879 shares of common stock for $5.9 million, during the year ended December 31, 2016.  There
were no share repurchases under the 2015 Share Repurchase Program during the years ended December 31, 2018 and 2017.  The
Company has elected not to hold treasury shares and therefore has retired the shares as they are repurchased.  It is the Company’s
accounting policy to record the excess paid over par value as a reduction in retained earnings for all shares repurchased.

to currency translation adjustments.



Note 23 – Business Acquisitions



In March 2018, the Company purchased certain
formulations and product technology for the mining industry for its North America reportable operating segment 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 agreement, $0.5 million of the purchase price was paid at signing, with
the remaining $0.5 million of the purchase price being paid during the first quarter of 2019.  As of December 31, 2018, the
remaining $0.5 million was recorded in Other current liabilities on the Company’s Consolidated Balance Sheet.



In December 2017, the Company acquired
the remaining 45% ownership interest in its India affiliate, Quaker Chemical India Private Limited (“QCIL”) for 2,025.0
million INR, or approximately $31.8 million.  QCIL is a part of the Company’s Asia/Pacific reportable operating segment. 
As this acquisition was a change in an existing controlling ownership, the Company recorded $21.2 million of excess purchase price
over the carrying value of the noncontrolling interest in Capital in excess of par value.  In May 2017, the Company acquired
assets associated with a business that markets, sells and manufactures certain metalworking fluids for its North America reportable
operating segment for 7.3 million CAD, or approximately $5.4 million.  As of December 31, 2018, the allocation of the purchase
price for all of the Company’s 2017 acquisitions have been finalized.



In November 2016, the Company acquired
Lubricor Inc. and its affiliated entities (“Lubricor”), a metalworking fluids manufacturer headquartered in Waterloo,
Ontario for its North America reportable operating segment for 16.0 million CAD, or approximately $12.0 million.  During the
first quarter of 2017, the Company identified and recorded an adjustment of less than $0.1 million to the allocation of the purchase
price for the Lubricor acquisition.  The adjustment was the result of finalizing a post-closing settlement based on the Company’s
assessment of additional information related to assets acquired and liabilities assumed.  In May 2016, the Company acquired
assets of a business that is associated with dust control products for the mining industry for its North America reportable
operating segment for $1.9 million.  As of December 31, 2017, the allocation of the purchase price for all of the Company’s
2016 acquisitions have been finalized.



In July 2015, the Company acquired Verkol,
a leading specialty grease and other lubricants manufacturer based in northern Spain, included in its EMEA reportable operating
segment, for 37.7 million EUR, or approximately $41.4 million.  This includes a post-closing adjustment of 1.3 million EUR,
or approximately $1.4 million that was accrued as of December 31, 2015 and paid during the first quarter of 2016.

The fair values of Company-owned life insurance
are based on quotes for like instruments with similar credit ratings and terms.  The Company did not have liabilities subject
to fair value measurement and did not hold Level 3 investments as of December 31, 2018 or 2017, respectively, so related disclosures
have not been included.



Note 25 – Commitments and Contingencies



In 1992, the Company identified certain
soil and groundwater contamination at AC Products, Inc. (“ACP”), a wholly owned subsidiary.  In voluntary coordination
with the Santa Ana California Regional Water Quality Board, ACP has been remediating the contamination, the principal contaminant
of which is perchloroethylene (“PERC”).  In 2004, the Orange County Water District (“OCWD”) filed
a civil complaint against ACP and other parties seeking to recover compensatory and other damages related to the investigation
and remediation of the contamination in the groundwater.  Pursuant to a settlement agreement with OCWD, ACP agreed, among
other things, to operate the two groundwater treatment systems to hydraulically contain groundwater contamination emanating from
ACP’s site until the concentrations of PERC released by ACP fell below the current Federal maximum contaminant level for
four consecutive quarterly sampling events.  In 2014, ACP ceased operation at one of its two groundwater treatment systems,
as it had met the above condition for closure.  As of December 31, 2018, ACP believes it is close to meeting the conditions
for closure of the remaining groundwater treatment system but continues to operate this system while in discussions with the relevant
authorities.



As of December 31, 2018, the Company believes
that the range of potential-known liabilities associated with the balance of ACP water remediation program is approximately $0.1
million to $1.0 million.  The low and high ends of the range are based on the length of operation of the treatment system
as required by the conditions noted above, as determined by groundwater modeling.  Costs of operation include the operation
and maintenance of the extraction well, groundwater monitoring and program management.



The Company believes, although there can
be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated
with other environmental problems of which it is aware.  Approximately $0.2 million was accrued as of December 31, 2018 and
2017, respectively, to provide for such anticipated future environmental assessments and remediation costs.

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.  The subsidiary discontinued operations in 1991 and has no
remaining assets other than proceeds received from insurance settlements.  To date, the overwhelming majority of these claims
have been disposed of without payment and there have been no adverse judgments against the subsidiary.  Based on a 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).  Although
the Company has also been named as a defendant in certain of these cases, no claims have been actively pursued against the Company,
and the Company has not contributed to the defense or settlement of any of these cases pursued against the subsidiary.  These
cases were handled by the subsidiary’s primary and excess insurers who had agreed in 1997 to pay all defense costs and be
responsible for all damages assessed against the subsidiary arising out of existing and future asbestos claims up to the aggregate
limits of their policies.  A significant portion of this primary insurance coverage was provided by an insurer that is insolvent,
and the other primary insurers asserted that the aggregate limits of their policies had been exhausted.  The subsidiary challenged
the applicability of these limits to the claims being brought against the subsidiary.  In response, two of the three carriers
entered into separate settlement and release agreements with the subsidiary in 2005 and 2007 for $15.0 million and $20.0 million,
respectively.  The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated
with the subsidiary’s asbestos litigation.





In 2007, the subsidiary and the
remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier is paying 27%
of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims. 
The agreement continues until terminated and can only be terminated by either party by providing a minimum of two years prior
written notice.  As of December 31, 2018, no notice of termination has been given under this agreement.  At the end
of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application
of the policy limits.  The Company believes that, if the coverage issues under the primary policies with the remaining carrier
are resolved adversely to the subsidiary and all settlement proceeds were used, the subsidiary may have limited additional coverage
from a state guarantee fund established following the insolvency of one of the subsidiary’s primary insurers.  Nevertheless,
liabilities in respect of claims may exceed the assets and coverage available to the subsidiary.



If the subsidiary’s assets and insurance
coverage were to be exhausted, claimants of the subsidiary may actively pursue claims against the Company because of the parent-subsidiary
relationship.  The Company does not believe that such claims would have merit or that the Company would be held to have liability
for any unsatisfied obligations of the subsidiary as a result of such claims.  After evaluating the nature of the claims filed
against the subsidiary and the small number of such claims that have resulted in any payment, the potential availability of additional
insurance coverage at the subsidiary level, the additional availability of the Company’s own insurance and the Company’s
strong defenses to claims that it should be held responsible for the subsidiary’s obligations because of the parent-subsidiary
relationship, the Company believes it is not probable that the Company will incur losses.  The Company has been successful
to date having any claims naming it dismissed during initial proceedings.  Since the Company may be in this stage of litigation
for some time, it is not possible to estimate additional losses or range of loss, if any.



The Company is party to other litigation
which management currently believes will not have a material adverse effect on the Company’s results of operations, cash
flows or financial condition.



The Company leases certain manufacturing
and office facilities and equipment under non-cancelable operating leases with various terms from 1 to 15 years expiring in 2027.
Rent expense for the years ended December 31, 2018, 2017 and 2016 was $7.2 million, $6.4 million, and $5.6 million, respectively.



The Company’s minimum rental commitments
under operating leases as of December 31, 2018 for future years were approximately:



|2019            |  |  | $ | 7,068 |

Item 9A.  Controls and Procedures.



Conclusion Regarding the Effectiveness of Disclosure Controls
and Procedures



As required by Rule 13a-15(b) under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), our management, including our principal executive
officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined
in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report.  At the time we filed the Original
Filing, our principal executive officer and principal financial officer had concluded that as of December 31, 2018 our disclosure
controls and procedures were effective. Subsequent to that evaluation, PricewaterhouseCoopers LLP, the independent registered public
accounting firm of the Company, performed an internal review over its 2018 audit of the Company’s consolidated financial
statements as reported in the Original Filing. Following this review, our principal executive officer and principal financial officer
concluded that our disclosure controls and procedures were not effective as of December 31, 2018 because of the material weakness
in our internal control over financial reporting, as described below.



Notwithstanding this material weakness,
the Company has concluded that no material misstatements exist in the consolidated financial statements as filed in the Original
Filing, and as included in this Amended Filing, and such financial statements present fairly, in all material respects, the financial
position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the
years in the three-year period ended December 31, 2018, in conformity with accounting principles generally accepted in the United
States of America.



Restated Management’s Report on Internal Control
over Financial Reporting



The management of Quaker is responsible
for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rule 13a-15(f) promulgated
under the Exchange Act.  Internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles.



Because of its inherent limitations, internal
control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness
to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree
of compliance with the policies or procedures may deteriorate.



Our management, with the
participation of our principal executive officer and principal financial officer, assessed the effectiveness of the
Company’s internal control over financial reporting as of December 31, 2018.  In making this assessment, our
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal
Control—Integrated Framework (2013).  A material weakness is a deficiency, or combination of deficiencies, in
internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual
or interim financial statements will not be prevented or detected on a timely basis. The Company did not design and maintain
effective internal control over certain aspects of its information technology. Specifically, we did not design and maintain
effective controls related to (i) user access controls to adequately restrict user and privileged access to certain financial
applications and data to the appropriate personnel, including ensuring appropriate segregation of duties as it relates to the
preparation and review of journal entries and (ii) monitoring, documenting and approving system or data changes. This control
deficiency did not result in a misstatement of the Company’s consolidated financial statements. However, this control
deficiency could result in misstatements of the interim or annual consolidated financial statements and disclosures that
would result in a material misstatement that would not be prevented or detected. Therefore, management has concluded that
this control deficiency constitutes a material weakness.



In Management’s Report on Internal
Control over Financial Reporting included in the Original Filing, our management previously concluded that the Company maintained
effective internal control over financial reporting as of December 31, 2018. Subsequent to the filing date of the Original Filing,
management has concluded that the material weakness described above existed as of December 31, 2018. As a result, we have concluded
that we did not maintain effective internal control over financial reporting as of December 31, 2018, based on the criteria in
Internal Control—Integrated Framework(2013). Accordingly, management has restated its report on internal control
over financial reporting.



50









The effectiveness of the Company’s
internal control over financial reporting as of December 31, 2018 has been audited by PricewaterhouseCoopers LLP, an independent
registered public accounting firm, as stated in their report, which is included in “Item 8. Financial Statements and Supplementary
Data” of this Amended Filing.



Plan for Remediation of Material Weakness





The Company and its Board of Directors
are committed to maintaining a strong internal control environment. Management has evaluated the material weakness described above
and has made significant progress updating its design and implementation of internal controls to remediate the aforementioned control
deficiency and enhance the Company’s internal control environment. The remediation plan is being implemented and includes
a revised risk assessment coupled with additional controls and procedures. Management is committed to successfully implementing
the remediation plan as promptly as possible, and currently plans to evaluate its updated internal controls design and determine
whether the controls have operated effectively during the third quarter of 2019 in order to fully remediate the aforementioned
material weakness in the Company’s internal control over financial reporting.





Changes in Internal Controls Over Financial Reporting



As required by Rule 13a-15(d) under the
Exchange Act, our management, including our principal executive officer and principal financial officer, has evaluated our internal
control over financial reporting to determine whether any changes to our internal control over financial reporting occurred during
the fourth quarter of the year ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect,
our internal control over financial reporting.  Based on that evaluation, no such changes to our internal control over financial
reporting occurred during the fourth quarter of the year ended December 31, 2018.
