1. Background and Basis of Presentation:

Description of Business

PQ Group Holdings Inc. and subsidiaries (the “Company” or “PQ Group Holdings”) is a leading integrated and innovative global provider of specialty catalysts, materials and chemicals, and services. The Company supports customers globally through its strategically located network of manufacturing facilities. The Company believes that its products, which are predominantly inorganic, and services contribute to improving the sustainability of the environment.

The Company has four uniquely positioned specialty businesses: Refining Services provides sulfuric acid recycling to the North American refining industry; Catalysts serves the global refining, petrochemical and emissions control industries; Performance Materials produces transportation reflective safety markings for roads and airports; and Performance Chemicals supplies diverse product end uses, including personal and industrial cleaning products, fuel-efficient tires, surface coatings, and food and beverage products.

Effective March 1, 2019, the Company changed the structure of its internal organization to create the four independent businesses described above in order to promote increased visibility to business unit performance, optimize the Company’s product portfolio and create efficiencies. Previously, the Company had two reportable segments, namely the Environmental Catalysts and Services segment and the Performance Materials and Chemicals segment. Beginning with the quarter ended March 31, 2019, the segment results and disclosures included in the Company’s consolidated financial statements reflect the new segment structure for all periods presented. The changes to the Company’s segment structure affect only the manner in which the results of the Company’s reportable segments were previously reported; there are no changes to the Company’s consolidated balance sheet, statement of income or cash flows for the prior periods. For the purposes of the Company’s goodwill impairment testing, the four new operating segments align with the Company’s reporting units at which level goodwill has been assigned and historically tested for impairment.

Seasonal changes and weather conditions typically affect the Company’s Performance Materials and Refining Services segments. In particular, the Company’s Performance Materials segment generally experiences lower sales and profit in the first and fourth quarters of the year because highway striping projects typically occur during warmer weather months. Additionally, the Company’s Refining Services segment typically experiences similar seasonal fluctuations as a result of higher demand for gasoline products in the summer months. As a result, working capital requirements tend to be higher in the first and second quarters of the year, which can adversely affect the Company’s liquidity and cash flows. Because of this seasonality associated with certain of the Company’s segments, results for any one quarter are not necessarily indicative of the results that may be achieved for any other quarter or for the full year.

Basis of Presentation

The condensed consolidated financial statements included herein are unaudited. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations for interim reporting. In the opinion of management, all adjustments of a normal and recurring nature necessary to state fairly the financial position and results of operations have been included. The results of operations are not necessarily indicative of the results to be expected for the full year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Other than the update to our lease accounting policies described in Note 11 , the Company has continued to follow the accounting policies set forth in those consolidated financial statements.

2. New Accounting Standards:

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board (“FASB”) issued guidance (with subsequent targeted amendments) that modifies the accounting for leases. Under the new guidance, a lessee will recognize right-of-use lease assets and lease liabilities for most leases (including those classified under existing GAAP as operating leases, which based on previous standards are not reflected on the balance sheet), but will recognize expenses in a manner that is generally consistent with existing practices. The new guidance also requires companies to provide expanded disclosures regarding leasing arrangements. For public companies, the new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. The new guidance must be adopted using a modified retrospective transition method.

(unaudited)

The Company adopted the new lease guidance effective January 1, 2019 as required using the modified retrospective transition method and applied the provisions of the guidance at the effective date with a cumulative-effect adjustment to the opening balance of retained earnings without adjusting the comparative periods presented. The new guidance provides practical expedients and allows for certain policy elections with regard to the Company’s lease population. The Company has elected the short term lease accounting policy and will not record right-of-use lease assets or lease liabilities for leases with an initial term of twelve months or less. Additionally, the Company has elected to utilize the portfolio approach to apply incremental borrowing rates to its leases. The Company has elected the package of practical expedients which provides the Company with the ability to bypass reassessment of the following for leases existing at the date of adoption: (1) whether any existing contracts are, or contain, leases; (2) the lease classification for any existing leases; and (3) initial direct costs for any existing leases. The Company also elected the land easement practical expedient to carry forward existing accounting treatment on existing land easements.

Adoption of the new lease guidance resulted in the recognition of right-of-use lease assets of $60,726 , which included $57,832 of right-of-use lease assets related to lease commitments and $2,895 related to the reclassification of favorable lease contracts, and lease liabilities of $58,929 . The new guidance had no impact on the Company’s operating results or liquidity upon adoption. Disclosures related to the Company’s leases are included in Note 11 to these condensed consolidated financial statements.

In February 2018, the FASB issued guidance which permits entities to make a one-time election to reclassify the residual (“stranded”) income tax effects included in accumulated other comprehensive income (“AOCI”) to beginning retained earnings as a result of tax reform legislation enacted by the U.S. government on December 22, 2017. The standard is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Prior to the enactment of the tax reform legislation on December 22, 2017, the Company had amounts recorded in AOCI related to its domestic pension, postretirement and supplementary benefit plans and cash flow hedging relationships that were based on pre-enactment tax rates, which were included in AOCI at the adoption date of the new guidance. The Company adopted the new guidance effective January 1, 2019 as required, and reclassified the income tax effects stranded in AOCI of $1,874 from AOCI to beginning retained earnings.

In June 2018, the FASB issued guidance which conforms the accounting for the issuance of all share-based payments using the same accounting model. Previously, the accounting for share-based payments to non-employees was covered under a different framework than those made to employees. Under the new guidance, awards to both employees and non-employees will essentially follow the same model, with small variations related to determining the term assumption when valuing a non-employee award as well as a different expense attribution model for non-employee awards. The new guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company adopted the new guidance on January 1, 2019 as required, with no material impact on its consolidated financial statements upon adoption.

Accounting Standards Not Yet Adopted

In August 2018, the FASB issued guidance which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance eliminates certain disclosure requirements, including the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and the effects of a one-percentage point change in assumed health care cost trend rates. The guidance also requires additional disclosure of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The guidance is effective for fiscal years ending after December 15, 2020 with early adoption permitted, and is required to be applied on a retrospective basis to all periods presented. The Company will modify its benefit plan disclosures in accordance with the new guidance upon adoption, and the guidance will not have a material impact on its consolidated financial statements.

In August 2018, the FASB issued guidance which modifies certain disclosure requirements over fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, including all interim periods within that fiscal year. The Company believes that the new guidance will not have a material impact on its consolidated financial statements.

In January 2017, the FASB issued guidance which eliminates the second step from the traditional two-step goodwill impairment test. Under current guidance, an entity performed the first step of the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount; if an impairment loss was indicated, the entity computed the implied fair value of goodwill to determine whether an impairment loss existed, and if so, the amount to recognize. Under the new guidance, an impairment loss is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value (the Step 1 test), with no further testing required. Any impairment loss recognized is limited to the amount of goodwill allocated to the reporting unit. The new guidance is effective for public companies that are Securities and Exchange Commission (“SEC”) registrants for fiscal years beginning after December 15, 2019, with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company will apply the guidance prospectively to goodwill impairment tests subsequent to the adoption date.

In June 2016, the FASB issued guidance that affects loans, trade receivables and any other financial assets that have the contractual right to receive cash. Under the new guidance, an entity is required to recognize expected credit losses rather than incurred losses for financial assets. The new guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company believes that the new guidance will not have a material impact on its consolidated financial statements.

Contract Assets and Liabilities

A contract asset is a right to consideration in exchange for goods that the Company has transferred to a customer when that right is conditional on something other than the passage of time. A contract liability exists when the Company receives consideration in advance of performance obligations. The Company has not recorded any contract assets or contract liabilities on its condensed consolidated balance sheets as of March 31, 2019 and December 31, 2018 .

4. Fair Value Measurements:

Fair values are based on quoted market prices when available. When market prices are not available, fair values are generally estimated using discounted cash flow analyses, incorporating current market inputs for similar financial instruments with comparable terms and credit quality. In instances where there is little or no market activity for the same or similar instruments, the Company estimates fair values using methods, models and assumptions that management believes a hypothetical market participant would use to determine a current transaction price. These valuation techniques involve some level of management estimation and judgment that becomes significant with increasingly complex instruments or pricing models. Where appropriate, adjustments are included to reflect the risk inherent in a particular methodology, model or input used.

The Company’s financial assets and liabilities carried at fair value have been classified based upon a fair value hierarchy. The hierarchy gives the highest ranking to fair values determined using unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). The classification of an asset or a liability is based on the lowest level input that is significant to its measurement. For example, a Level 3 fair value measurement may include inputs that are both observable (Levels 1 and 2) and unobservable (Level 3). The levels of the fair value hierarchy are as follows:


•	Level 1—Values are unadjusted quoted prices for identical assets and liabilities in active markets accessible at the measurement date. Active markets provide pricing data for trades occurring at least weekly and include exchanges and dealer markets.


•	Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are observable or can be corroborated by market data for the term of the instrument. Such inputs include market interest rates and volatilities, spreads and yield curves.


•	Level 3—Certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date.

The following table presents information about the Company’s assets and liabilities that were measured at fair value on a recurring basis as of March 31, 2019 and December 31, 2018 , and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value.

Restoration plan assets

The fair values of the Company’s restoration plan assets are determined through quoted prices in active markets. Restoration plan assets are assets held in a Rabbi trust to fund the obligations of the Company’s defined benefit supplementary retirement plans and include various stock and fixed income mutual funds. See Note 15 to these condensed consolidated financial statements regarding defined supplementary retirement plans. The Company’s restoration plan assets are included in other long-term assets on its condensed consolidated balance sheets. Gains and losses related to these investments are included in other expense, net in the Company’s condensed consolidated statements of income. Unrealized gains and losses associated with the underlying stock and fixed income mutual funds were immaterial as of March 31, 2019 and December 31, 2018 , respectively.

Derivative contracts

Derivative assets and liabilities can be exchange-traded or traded over-the-counter (“OTC”). The Company generally values exchange-traded derivatives using models that calibrate to market transactions and eliminate timing differences between the closing price of the exchange-traded derivatives and their underlying instruments. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, model calibration to market transactions, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. When models are used, the selection of a particular model to value an OTC derivative depends on the contractual terms of, and specific risks inherent in, the instrument as well as the availability of pricing information in the market. The Company generally uses similar models to value similar instruments. Valuation models require a variety of inputs, including contractual terms, market prices and rates, forward curves, measures of volatility, and correlations of such inputs. For OTC derivatives that trade in liquid markets, such as forward contracts, swaps and options, model inputs can generally be corroborated by observable market data by correlation or other means, and model selection does not involve significant management judgment.

The Company has interest rate caps, natural gas swaps and cross currency swaps that are fair valued using Level 2 inputs. In addition, the Company applies a credit valuation adjustment to reflect credit risk which is calculated based on credit default swaps. To the extent that the Company’s net exposure under a specific master agreement is an asset, the Company utilizes the counterparty’s default swap rate. If the net exposure under a specific master agreement is a liability, the Company utilizes a default swap rate comparable to PQ Group Holdings. The credit valuation adjustment is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the Company’s liabilities or that a market participant would be willing to pay for the Company’s assets.

11. Leases:

The Company has operating and finance lease agreements with remaining lease terms as of March 31, 2019 up to 28 years, including leases of land, buildings, railcars, vehicles, manufacturing equipment and general office equipment. Some leases include options to terminate or extend for one or more years. These options are incorporated in the Company’s lease term when it is reasonably certain that the option will be exercised. Some leases include options to purchase, which the Company assesses under the guidance to determine if these leases should be classified as finance lease agreements.

When the Company enters into an arrangement, at inception, the Company determines if the arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. maintenance). The Company accounts for the lease and non-lease components based on the estimated standalone price of each component. Certain of the Company’s lease agreements include rental payments that are adjusted periodically for an index or rate and these are initially measured using the index or rate in effect at the commencement date. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

(unaudited)

The Company recognizes a right-of-use lease asset and lease liability at the lease commencement date based on the present value of the remaining lease payments over the lease term using the Company’s incremental borrowing rate. The Company is required to use the rate of interest that it would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When the Company is unable to readily determine the discount rate implicit in the lease agreement, the Company utilizes its incremental borrowing rate over the relevant lease term. Short-term leases, which have an initial term of twelve months or less, are not recorded on the Company’s balance sheet.

Lease expense for operating leases and financing leases is recognized on a straight-line basis over the lease term and is included in cost of goods sold or selling, general, and administrative expense on the condensed consolidated statements of income.

The table below presents the operating and finance right-of-use lease assets and lease liabilities recognized on the condensed consolidated balance sheet as of March 31, 2019 :

As of March 31, 2019 and December 31, 2018 , the fair value of the term loan facility and senior secured and unsecured notes was $ 2,077,276 and $ 2,010,023 , respectively. The fair value is classified as Level 2 based upon the fair value hierarchy (see Note 4 to these condensed consolidated financial statements for further information on fair value measurements).

13. Financial Instruments:

The Company uses (1) interest rate related derivative instruments to manage its exposure to changes in interest rates on its variable-rate debt instruments, (2) commodity derivatives to manage its exposure to commodity price fluctuations, and (3) foreign currency related derivative instruments to manage its foreign currency exposure to its net investments in certain foreign operations. The Company does not speculate using derivative instruments.

By using derivative financial instruments to hedge exposures to changes in interest rates, commodity prices and foreign currency, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is an asset, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is a liability, the Company owes the counterparty and therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with high quality counterparties. The derivative instruments entered into by the Company do not contain credit-risk-related contingent features.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates, currency exchange rates or commodity prices. The market risk associated with the Company’s derivative instruments is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

Use of Derivative Financial Instruments to Manage Commodity Price Risk. The Company is exposed to risks in energy costs due to fluctuations in energy prices, particularly natural gas. The Company has a hedging program in the United States which allows the Company to mitigate exposure to natural gas volatility with natural gas swap agreements. Fair value is determined based on estimated amounts that would be received or paid to terminate the contracts at the reporting date based on quoted market prices of comparable contracts. The respective current and non-current liabilities are recorded in accrued liabilities and other long-term liabilities and the respective current and non-current assets are recorded in prepaid and other current assets and other long-term assets, as applicable, in the Company’s consolidated balance sheet. As the derivatives are designated and qualify as cash flow hedges, the gains or losses on the natural gas swaps are recorded in stockholders’ equity as a component of other comprehensive income (loss) (“OCI”), net of tax. Reclassifications of the gains and losses on natural gas hedges into earnings are recorded in production costs and subsequently charged to cost of goods sold in the condensed consolidated statements of income in the period in which the associated inventory is sold. As of March 31, 2019 , the Company’s natural gas swaps had a remaining notional quantity of 3.3 million MMBTU to mitigate commodity price volatility through December 2021.

Use of Derivative Financial Instruments to Manage Interest Rate Risk. The Company is exposed to fluctuations in interest rates on its senior secured credit facilities. Changes in interest rates will not affect the market value of such debt but will affect the Company’s interest payments over the term of the loans. Likewise, an increase in interest rates could have a material impact on the Company’s cash flow. The Company hedges the interest rate fluctuations on debt obligations through interest rate cap agreements. The Company records these agreements at fair value as assets or liabilities in its consolidated balance sheet. As the derivatives are designated and qualify as cash flow hedges, the gains or losses on the interest rate cap agreements are recorded in stockholders’ equity as a component of OCI, net of tax. Reclassifications of the gains and losses on the interest rate cap agreements into earnings are recorded as part of interest expense in the condensed consolidated statements of income as the Company makes its interest payments on the hedged portion of its senior secured credit facilities. Fair value is determined based on estimated amounts that would be received or paid to terminate the contracts at the reporting date based on quoted market prices.

In July 2016, the Company entered into interest rate cap agreements, paying a premium of $1,551 to mitigate interest rate volatility from July 2016 through July 2020 by employing varying cap rates, ranging from 1.50% to 3.00% , on $1,000,000 of notional variable-rate debt. The cap rate currently in effect at March 31, 2019 is 2.50% . In November 2018, the Company entered into additional interest rate cap agreements to mitigate interest rate volatility from July 2020 through July 2022, with a cap rate of 3.50% on $500,000 of notional variable-rate debt.

Use of Derivative Financial Instruments to Manage Foreign Currency Risk. The Company is exposed to risks related to its net investments in foreign operations due to fluctuations in foreign currency exchange rates, particularly between the United States dollar and the Euro. In February 2018, the Company entered into multiple cross currency interest rate swap arrangements with an aggregate notional amount of €280,000 ( $314,112 as of March 31, 2019 ) to hedge this exposure on the net investments of certain of its Euro-denominated subsidiaries. The Company records these swap agreements at fair value as assets or liabilities in its consolidated balance sheet. As the derivatives are designated and qualify as net investment hedges, changes in the fair value of the swaps attributable to changes in the spot exchange rates are recognized in cumulative translation adjustment (“CTA”) within OCI and are held there until the hedged net investments are sold or substantially liquidated. Changes in the fair value of the swaps attributable to the cross currency basis spread are excluded from the assessment of hedge effectiveness and are recorded in current period earnings. Upon such sale or liquidation, the amount recognized in CTA is reclassified to earnings and reported in the same line item as the gain or loss on the liquidation of the net investments.

The fair values of derivative instruments held as of March 31, 2019 and December 31, 2018 are shown below:

14. Income Taxes:

The effective income tax rate for the three months ended March 31, 2019 was 41.6% compared to (1,959.3)% for the three months ended March 31, 2018 . The Company’s effective income tax rate has fluctuated primarily because of changes in income mix (including the effect of loss companies), the impact of including foreign earnings in U.S. taxable income and changes in foreign exchange gains and losses, which create permanent differences in certain jurisdictions.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the three months ended March 31, 2019 was mainly due to the tax effect of permanent differences related to foreign currency exchange gain or loss, inclusion of foreign earnings in the U.S. as a result of recently enacted tax law, pre-tax losses with no associated tax benefit, prior year tax refunds not previously accrued for and state taxes.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the three months ended March 31, 2018 was mainly due to the tax effect of repatriating foreign earnings back to the United States as dividends offset by lower tax rates in foreign jurisdictions as compared to the U.S. tax rate, foreign withholdings taxes, state taxes and non-deductible transaction costs.

The Tax Cuts and Jobs Act of 2017 (“TCJA”) enacted certain provisions that became effective on January 1, 2018. These provisions include, but are not limited to, the new Global Intangible Low-Taxed Income (“GILTI”) tax rules. Due to the complexity of the new GILTI tax, the Company is continuing to evaluate the GILTI provision of the TCJA and its impact on the financial statements, which remains uncertain. Per guidance issued by the FASB, the Company is permitted to make an accounting policy election to either (1) treat the taxes incurred as a result of the GILTI provision as a current-period expense when incurred or (2) factor such amounts into its measurement of deferred taxes. At this time, the Company is electing to treat any tax expense incurred as a result of GILTI as a current-period expense. Additionally, in regards to GILTI’s impact in assessing the ability to realize deferred tax assets, the Company has made a policy election to use the tax law ordering approach.

With respect to operating results for the three months ended March 31, 2019 , the Company has continued to incorporate an estimate of the GILTI income inclusion when estimating annual effective tax rate used for U.S. GAAP purposes. The Company expects this amount to be included in its 2019 U.S. taxable income. However, the estimated 2019 GILTI income inclusion may change materially as the Company continues to evaluate future legislative or administrative guidance that is put forth, any updates to assumptions and figures used for the current estimate, or as a result of future changes to the Company’s current structure and business.

15. Benefit Plans:

The following information is provided for (1) the Company-sponsored defined benefit pension plans covering employees in the U.S. and certain employees at its foreign subsidiaries, (2) the Company-sponsored unfunded plans to provide certain health care benefits to retired employees in the U.S. and Canada, and (3) the Company’s defined benefit supplementary retirement plans which provide benefits for certain U.S. employees in excess of qualified plan limitations.

16. Commitments and Contingent Liabilities:

There is a risk of environmental impact in chemical manufacturing operations. The Company’s environmental policies and practices are designed to comply with existing laws and regulations and to minimize the possibility of significant environmental impact. The Company is also subject to various other lawsuits and claims with respect to matters such as governmental regulations, labor and other actions arising out of the normal course of business. While management believes that the liabilities resulting from such lawsuits and claims are not probable or reasonably estimable, certain accruals have been reflected in the Company’s condensed consolidated financial statements. When these matters are ultimately concluded and determined, the Company believes that there will be no material adverse effect on its consolidated financial position, results of operations or liquidity.

18. Stock-Based Compensation:

The Company is authorized to issue shares for common stock awards to employees, directors and affiliates of the Company in connection with the PQ Group Holdings Inc. 2017 Omnibus Incentive Plan (the “2017 Plan”). During the three months ended March 31, 2019 , the Company granted 1,196,141 restricted stock units and 539,431 performance stock units at target under the 2017 Plan as part of its equity incentive compensation program. Each restricted stock unit provides the recipient with the right to receive a share of common stock subject to graded vesting terms based on service, which for the awards granted during the three months ended March 31, 2019 , require approximately one year of service for members of the Company’s board of directors and approximately three years of service for employees.

The performance stock units granted during the three months ended March 31, 2019 provide the recipients with the right to receive shares of common stock dependent on the achievement of two Company-specific financial performance targets and the provision of service through the vesting date. Achievement of the metrics is measured based on the average levels of achievement across the three-year period from January 1, 2019 through December 31, 2021. Depending on the Company’s performance against the pre-determined thresholds for achievement, each performance stock unit award holder is eligible to earn a percentage of the target number of shares granted to the holder, ranging from zero to 200% . The performance stock units, to the extend earned, will vest on the date the Company’s compensation and governance committee certifies the achievement of the performance metrics for the three -year period ending December 31, 2021, which will not occur later than March 1, 2022.

The value of the restricted stock units granted during the three months ended March 31, 2019 was based on the average of the high and low trading prices of the Company’s common stock on the NYSE on the preceding trading day, in accordance with the Company’s policy for valuing such awards. Compensation expense related to the restricted stock units is recognized on a straight-line basis over the respective vesting period. The value of the performance stock units granted during the three months ended March 31, 2019 was measured on the same basis as that of the restricted stock units, and based on the target number of shares granted; because the performance vesting conditions affect the ability of the recipients to vest in the awards, they are not factored into the fair value measure of the award.

Compensation expense related to the performance stock units is recognized ratably over the requisite service period, and the Company must assess the probability that the performance conditions will be met each reporting period, and the level at which they are estimated to be attained. Should the probability assessment change during a given reporting period, the total compensation cost (both recognized and unrecognized) will be adjusted to reflect the revised assessment.

The following table summarizes the activity for the Company’s restricted stock units and performance stock units for the three months ended March 31, 2019 :



	Restricted Stock Units				Performance Stock Units
	Number of Units		Weighted Average Grant Date Fair Value (per share)		Number of Units	Weighted Average Grant Date Fair Value (per share)
Nonvested as of December 31, 2018	998,786		$	16.83	—	$	—
Granted	1,196,141		$	15.41	539,431	$	15.41
Vested	(6,037	)	$	16.54	—	$	—
Nonvested as of March 31, 2019	2,188,890		$	16.06	539,431	$	15.41

Total stock-based compensation expense for all of the Company’s equity incentive awards for the three months ended March 31, 2019 and 2018 was $3,400 and $3,831 , respectively. With the new grants of restricted stock units and performance stock units during the three months ended March 31, 2019 , unrecognized compensation cost at March 31, 2019 related to nonvested awards was $ 29,715 and $ 8,159 for restricted stock units and performance stock units, respectively. The weighted-average period over which these costs are expected to be recognized at March 31, 2019 is 2.09 years for the restricted stock units and 2.92 years for the performance stock units.

At March 31, 2019 , 3,666,886 shares of common stock were available for issuance under the 2017 Plan, after giving effect to the new grants as well as other minor activity during the three months ended March 31, 2019 . Activity related to the Company’s stock options and restricted stock awards was not material for the three months ended March 31, 2019 .

19. Earnings per Share:

Basic earnings per share is calculated as income (loss) available to common stockholders, divided by the weighted average number of common shares outstanding during the period. The weighted average number of common shares outstanding during the period for the computation of basic earnings per share excludes restricted stock awards that have legally been issued but are nonvested during the period, as the sale of these shares is prohibited pending satisfaction of certain vesting conditions by the award recipients in order to earn the rights to the shares.

Diluted earnings per share is calculated as income (loss) available to common stockholders, divided by the weighted average number of common and potential common shares outstanding during the period, if dilutive. Potential common shares reflect (1) unvested restricted stock awards and restricted stock units with service vesting conditions, (2) performance stock units with vesting conditions considered probable of achievement and (3) options to purchase common stock, all of which have been included in the diluted earnings per share calculation using the treasury stock method.

The reconciliation from basic to diluted weighted average shares outstanding is as follows:



	Three months ended March 31,
	2019	2018
Weighted average shares outstanding – Basic	133,946,308	133,154,144
Dilutive effect of unvested common shares and restricted stock units with service conditions, performance stock units considered probable of vesting and assumed stock option exercises and conversions	948,046	730,839
Weighted average shares outstanding – Diluted	134,894,354	133,884,983

The table below presents the details of the Company’s weighted average equity-based awards outstanding during each respective period that were excluded from the calculation of diluted earnings per share:



	Three months ended March 31,
	2019	2018
Restricted stock awards with performance only targets not yet achieved	1,639,514	1,751,022
Stock options with performance only targets not yet achieved	586,253	586,253
Anti-dilutive restricted stock awards, restricted stock units and performance stock units	—	—
Anti-dilutive stock options	863,063	621,747

Restricted stock awards and stock options with performance only vesting conditions were not included in the dilution calculation, as the performance targets have not been achieved nor were probable of achievement as of the end of the respective periods. On a weighted average basis, options to purchase 621,747 shares of common stock at $16.97 per share for the three months ended March 31, 2019 and 2018 , and 241,316 shares of common stock at $17.50 per share for the three months ended March 31, 2019 were excluded from the computation of diluted earnings per share for the respective periods, because the combination of the options’ exercise price and remaining unamortized stock-based compensation expense was greater than the average market price of the common shares. The 621,747 stock options expire on October 2, 2027 while the 241,316 stock options expire on August 9, 2028. All of the options were outstanding as of March 31, 2019 . Anti-dilutive awards are not included in the dilution calculation, as their inclusion would have the effect of increasing diluted income per share.

Overview

We are a leading integrated and innovative global provider of specialty catalysts, materials and chemicals, and services. We support customers globally through our strategically located network of manufacturing facilities. We believe that our products, which are predominantly inorganic, and services contribute to improving the sustainability of the environment.

We conduct operations through four reporting segments: (1) Refining Services, (2) Catalysts (including the Zeolyst Joint Venture), (3) Performance Materials, and (4) Performance Chemicals.

Refining Services: We are the leading provider of sulfuric acid recycling services to North American refineries for the production of alkylate, an essential gasoline component for lowering vapor pressure and increasing octane to meet stringent gasoline specifications and fuel efficiency standards. We are also a leading North American producer of virgin sulfuric acid for water treatment, mining, and industrial applications.

Catalysts: We are a global supplier of finished silica catalysts and supports necessary to produce high strength and high stiffness plastics used in packaging films, bottles, containers, and other molded applications. We are also a leading global supplier of zeolites used for catalysts that remove NOx from diesel engine emissions as well as sulfur from fuels during the refining process.

Performance Materials: We are an industry leader in North America, Europe, and South America in transportation safety. Our products are used to delineate roads and runways with highly reflective markings, improving safety by enhancing visibility at night and in poor weather. Our microspheres also serve as functional additives in industrial applications, including polymers and plastics, and in abrasive applications for metal surfaces.

Performance Chemicals: We are a leading global supplier of silicate and derivative products which serve as an environmentally friendly substitute for materials used in a variety of applications. These include end uses such as matting agents in surface coatings, clarifying agents for edible oils and beverages, additives into paints and coatings for thermal insulation, and in cosmetics to improve feel attributes.

Effective March 1, 2019, we changed the structure of our internal organization to create the four independent businesses described above in order to promote increased visibility to business unit performance, optimize our product portfolio and create efficiencies. Previously, we had two reportable segments, namely the Environmental Catalysts and Services segment and the Performance Materials and Chemicals segment. Beginning with the quarter ended March 31, 2019, the segment results and disclosures included in our consolidated financial statements reflect the new segment structure for all periods presented. The changes to our segment structure affect only the manner in which the results of our reportable segments were previously reported; there are no changes to our consolidated balance sheet, statement of income or cash flows for the prior periods.

Key Performance Indicators

Adjusted EBITDA and Adjusted Net Income

Adjusted EBITDA and adjusted net income are financial measures that are not prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and that we use to evaluate our operating performance, for business planning purposes and to measure our performance relative to that of our competitors. Adjusted EBITDA and adjusted net income are presented

Table of Contents

as key performance indicators as we believe these financial measures will enhance a prospective investor’s understanding of our results of operations and financial condition. EBITDA consists of net income (loss) attributable to PQ Group Holdings before interest, taxes, depreciation and amortization. Adjusted EBITDA consists of EBITDA adjusted for (i) non-operating income or expense, (ii) the impact of certain non-cash, nonrecurring or other items included in net income (loss) and EBITDA that we do not consider indicative of our ongoing operating performance, and (iii) depreciation, amortization and interest of our 50% share of the Zeolyst Joint Venture. Adjusted net income consists of net income (loss) attributable to PQ Group Holdings adjusted for (i) non-operating income or expense and (ii) the impact of certain non-cash, nonrecurring or other items included in net income (loss) that we do not consider indicative of our ongoing operating performance. We believe that these non-GAAP financial measures provide investors with useful financial metrics to assess our operating performance from period-to-period by excluding certain items that we believe are not representative of our core business.

You should not consider adjusted EBITDA and adjusted net income in isolation or as alternatives to the presentation of our financial results in accordance with GAAP. The presentation of our adjusted EBITDA and adjusted net income financial measures may differ from similar measures reported by other companies and may not be comparable to other similarly titled measures. In evaluating adjusted EBITDA and adjusted net income, you should be aware that we are likely to incur expenses similar to those eliminated in this presentation in the future and that certain of these items could be considered recurring in nature. Our presentation of adjusted EBITDA and adjusted net income should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items. Reconciliations of adjusted EBITDA and adjusted net income to GAAP net income (loss) are included in the results of operations discussion that follows for each of the respective periods.

Key Factors and Trends Affecting Operating Results and Financial Condition

Sales

Our Refining Services and Catalysts segments’ sales have grown primarily due to expansion into applications including emission control catalysts, polymer catalysts, and refining catalysts, as well as continued supply share gains. Sales in our Refining Services and Catalysts segments are made on both a purchase order basis and pursuant to long-term contracts.

Historically, our Performance Materials and Performance Chemicals segments have experienced relatively stable demand throughout economic cycles due to the diverse consumer and industrial end uses that our products serve. Expansions into new applications, including personal care and consumer cleaning, as well as share gains in existing end uses, have added to our sales growth. Product sales from our Performance Chemicals segment are made on both a purchase order basis and pursuant to long-term contracts. In the Performance Materials segment, sales have been driven by the growth of spending on repair, maintenance and upgrade of existing highways and the construction of new highways and roads by governments around the world. Product sales in our Performance Materials segment are made principally on a purchase order basis. There may be modest fluctuations in timing of orders, but orders are mainly driven by demand and general economic conditions.

Cost of Goods Sold

Cost of goods sold consists of variable product costs, fixed manufacturing expenses, depreciation expense and freight expenses. Variable product costs include all raw materials, energy and packaging costs that are directly related to the manufacturing process. Fixed manufacturing expenses include all plant employment costs, manufacturing overhead and periodic maintenance costs. The primary raw materials for our Refining Services segment include spent sulfuric acid, sulfur, sodium silicates, acids, bases, and certain metals. Most of our Refining Services contracts feature take-or-pay volume protection and/or price adjustments for commodity inputs, labor, the Chemical Engineering Index (U.S. chemical plant construction cost index) and natural gas. Spent acid for our Refining Services segment is supplied by customers for a nominal charge as part of their contracts. Over 80% of our Refining Services segment sales for the year ended December 31, 2018 were under contracts featuring price adjustments. The price adjustments generally reflect actual costs for producing acid and tend to protect us from volatility in labor, fixed costs and raw material pricing.

The primary raw materials used in the manufacture of products in our Performance Materials, Performance Chemicals and Catalysts segments include soda ash, industrial sand, aluminum trihydrate, sodium hydroxide, and cullet. For the year ended December 31, 2018 , approximately 40% of sales with our largest sodium silicate customers in North America were made under contracts that include price adjustments for changes in the price of raw materials and natural gas. Under these contracts, there generally is a time lag of three to nine months for price changes to pass through, depending on the magnitude of the change in cost and other market dynamics. Freight expenses are generally passed through directly to customers.

While natural gas is not a direct feedstock for any product, all businesses use natural gas powered furnaces to heat raw materials and create the chemical reactions necessary to produce end-products. We maintain multiple suppliers wherever possible, hedge exposure to fluctuations in prices for natural gas purchases in the United States, make forward purchases of natural gas in the United States, Canada, and Europe to mitigate our exposure to price volatility, and structure our customer contracts when possible to allow for the pass-through of raw material and natural gas costs.

Joint Ventures

We account for our investments in our equity joint ventures under the equity method. Our largest joint venture, the Zeolyst Joint Venture, manufactures high performance specialty zeolite-based catalysts for use in the emissions control industry, the petrochemical industry and other areas of the broader chemicals industry. We share proportionally in the management of our joint ventures with the other parties to each such joint venture.

Seasonality

Seasonal changes and weather conditions typically affect our Performance Materials and Refining Services segments. In particular, our Performance Materials segment generally experiences lower sales and profit in the first and fourth quarters of the year because highway striping projects typically occur during warmer weather months. Additionally, our Refining Services segment typically experiences similar seasonal fluctuations as a result of higher demand for gasoline products in the summer months. As a result, working capital requirements tend to be higher in the first and second quarters of the year, which can adversely affect our liquidity and cash flows. Because of this seasonality associated with certain of our segments, results for any one quarter are not necessarily indicative of the results that may be achieved for any other quarter or for the full year.

Foreign Currency

As a global business, we are subject to the impact of gains and losses on currency translations, which occur when the financial statements of foreign operations are translated into U.S. dollars. We operate a geographically diverse business with approximately 40% of our sales for the three months ended March 31, 2019 and the year ended December 31, 2018 , respectively, in currencies other than the U.S. dollar. Because our consolidated financial results are reported in U.S. dollars, sales or earnings generated in currencies other than the U.S. dollar can result in a significant increase or decrease in the amount of those sales and earnings when translated to U.S. dollars. The foreign currencies to which we have the most significant exchange rate exposure include the Euro, British pound, Canadian dollar, Brazilian real and the Mexican peso.

Refining Services: Sales in Refining Services for the three months ended March 31, 2019 were $105.8 million , an increase of $5.1 million , or 5.1% , compared to sales of $100.7 million for the three months ended March 31, 2018 . The increase in sales was primarily due to higher average selling prices and favorable customer mix of $8.6 million , which offset lower volumes of $3.5 million .

The increase in higher average selling price and customer mix was driven by contract renewals in our regenerated sulfuric acid product line and higher cost pass-through pricing in our virgin sulfuric acid product line. This more than offset a decrease in volumes due to unplanned customer plant outages.

Catalysts: Sales in Catalysts for the three months ended March 31, 2019 were $15.9 million , a decrease of $0.6 million , or 3.6% , compared to sales of $16.5 million for the three months ended March 31, 2018 . The decrease in sales was primarily due to lower volumes of $0.9 million and the unfavorable effects of foreign currency translation of $0.6 million , which was offset by higher average selling price and customer mix of $0.9 million .

Table of Contents

The change in sales was due to foreign exchange impact and lower volumes of products sold to the packaging and engineered plastics industries offset by favorable product and customer mix.

Performance Materials: Sales in Performance Materials for the three months ended March 31, 2019 were $61.1 million , a decrease of $1.6 million , or 2.6% , compared to sales of $62.7 million for the three months ended March 31, 2018 . The decrease in sales was primarily due to the unfavorable effects of foreign currency translation of $3.2 million and lower volumes of $1.3 million , which was partially offset by higher average selling price and favorable customer mix of $2.9 million .

The decrease in sales was a result of lower volumes of product sold to the electronics industry and the stronger U.S. dollar as compared to the Euro and Argentinian Peso. This was partially offset by higher average selling prices in North and Latin America.

Performance Chemicals: Sales in Performance Chemicals for the three months ended March 31, 2019 were $180.5 million , a decrease of $9.5 million , or 5.0% , compared to sales of $190.0 million for the three months ended March 31, 2018 . The decrease in sales was primarily due to the unfavorable effects of foreign currency translation of $8.6 million and lower sales volumes of $6.5 million , which was partially offset by higher average selling price and favorable customer mix of $5.6 million .

The decrease in sales was a result of lower volumes of product sold to the consumer products industry and the unfavorable effects of foreign currency driven by the stronger U.S. dollar, which was partially offset by favorable cost pass-through pricing.

Gross Profit

Gross profit for the three months ended March 31, 2019 was $80.9 million , an increase of $2.8 million , or 3.6% , compared with $78.1 million for the three months ended March 31, 2018 . The increase in gross profit was due to favorable customer pricing of $18.0 million , favorable product mix of $4.8 million and lower depreciation expense of $3.1 million , which was partially offset by unfavorable manufacturing costs of $14.1 million , lower volumes of $6.1 million and the unfavorable effects of foreign currency translation of $2.9 million .

Favorable customer pricing was a result of contract renewals and improved product mix. The unfavorable change in manufacturing costs was driven by higher raw material costs, some of which are passed through in price, and increased production and transportation costs. The decrease in volumes was due to customer plant outages and lower sales to the consumer products industry. The unfavorable effects of foreign currency were driven by the stronger U.S. dollar.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended March 31, 2019 were $40.7 million , an increase of $0.1 million compared with $40.6 million for the three months ended March 31, 2018 . Selling, general and administrative expenses were generally consistent with expenses incurred in the prior year, with increases in employment costs offset by lower spending due to cost management programs.

Other Operating Expense, Net

Other operating expense, net for the three months ended March 31, 2019 was $10.8 million , an increase of $1.5 million , compared with $9.3 million for the three months ended March 31, 2018 . During the three months ended March 31, 2018 , we recognized insurance recoveries totaling $1.5 million related to losses sustained as a result of Hurricane Harvey in August 2017 (of which $1.2 million was recorded in other operating expense, net), and which claim was fully settled by the end of 2018.

Equity in Net Income of Affiliated Companies

Equity in net income of affiliated companies for the three months ended March 31, 2019 was $2.1 million , compared to $11.9 million for the three months ended March 31, 2018 . The decrease was primarily due to $9.8 million of lower earnings from our Zeolyst Joint Venture during the three months ended March 31, 2019 . The decrease in earnings from our Zeolyst Joint Venture was due to lower sales to the fuels and emission control industries.

Interest Expense, Net

Interest expense, net for the three months ended March 31, 2019 was $28.6 million , a decrease of $0.6 million , as compared with $29.2 million for the three months ended March 31, 2018 . The decrease in interest expense is due to lower average debt balances, mainly as a result of the prepayment of $100.0 million related to the outstanding principal balance on our senior secured term loan facility during the third and fourth quarters of the year ended December 31, 2018 .

Debt Extinguishment Costs

Debt extinguishment costs for the three months ended March 31, 2018 was $5.9 million . On February 8, 2018 we refinanced our existing senior secured term loan facility with a new $1,267.0 million senior secured term loan facility to reduce the applicable interest rates. We recorded $2.1 million of new creditor and third-party financing fees as debt extinguishment costs for the three

Table of Contents

months ended March 31, 2018 . In addition, previous unamortized deferred financing costs of $1.4 million and original issue discount of $2.4 million associated with the existing senior secured term loan facility were written off as debt extinguishment costs for the three months ended March 31, 2018 .

Other (Income) Expense, Net

Other (income) expense, net for the three months ended March 31, 2019 was income of $3.0 million , a decrease of $8.0 million , as compared with an expense of $5.0 million for the three months ended March 31, 2018 . The change in other (income) expense, net primarily consisted of a decrease of $7.8 million of foreign currency losses driven by the non-permanent intercompany debt denominated in local currency and translated to U.S. dollars.

Provision (Benefit) for Income Taxes

The provision for income taxes for the three months ended March 31, 2019 was $2.4 million compared to a $0.5 million benefit for the three months ended March 31, 2018 . The effective income tax rate for the three months ended March 31, 2019 was 41.6% compared to (1,959.3)% for the three months ended March 31, 2018 .

The Company’s effective income tax rate fluctuates based primarily on changes in income mix (including the effect of loss companies), impact of including foreign earnings in U.S. taxable income and changes in foreign exchange gains and losses, which create permanent differences in certain jurisdictions.

The difference between the U.S. federal statutory income tax rate and the Company’s effective income tax rate for the three months ended March 31, 2019 was mainly due to the tax effect of permanent differences related to foreign currency exchange gain or loss, the inclusion of foreign earnings in U.S. taxable income, pre-tax losses with no associated tax benefit, prior year tax refunds not previously accrued for and state taxes.

Net Income Attributable to PQ Group Holdings

For the foregoing reasons and after the effect of the non-controlling interest in earnings of subsidiaries for each period presented, net income attributable to PQ Group Holdings was $3.2 million for the three months ended March 31, 2019 compared with net income of $0.2 million for the three months ended March 31, 2018 .

^(a)	We use Adjusted EBITDA as a performance measure to evaluate our financial results. Because our Catalysts segment includes our 50% interest in our Zeolyst Joint Venture, we include an adjustment for our 50% proportionate share of depreciation, amortization and interest expense of our Zeolyst Joint Venture.

^(b)

Represents the amortization of the fair value adjustments associated with the equity affiliate investment in our Zeolyst Joint Venture as a result of the combination of the businesses of PQ Holdings Inc. and Eco Services Operations LLC in May 2016 (the “Business Combination”). We determined the fair value of the equity affiliate investment and the fair value step-up was then attributed to the underlying assets of our Zeolyst Joint Venture. Amortization is primarily related to the fair value adjustments associated with fixed assets and intangible assets, including customer relationships and technical know-how.


^(c)	As a result of the Sovitec acquisition there was a step-up in the fair value of inventory, which is amortized through cost of goods sold in the statements of income.


^(d)	When asset disposals occur, we remove the impact of net gain/loss of the disposed asset because such impact primarily reflects the non-cash write-off of long-lived assets no longer in use.

^(e)

Reflects the exclusion of the foreign currency transaction gains and losses in the statements of income primarily relates to the non-permanent intercompany debt denominated in local currency translated to U.S. dollars for the three months ended March 31, 2019 and primarily relates to the Euro denominated term loan (which was settled as part of the February 2018 term loan refinancing) for the three months ended March 31, 2018 .


^(f)	Represents non-cash adjustments to the Company’s LIFO reserves for certain inventories in the U.S. that are valued using the LIFO method, which we believe provides a means of comparison to other companies that may not use the same basis of accounting for inventories.

Table of Contents


^(g)	Relates to certain transaction costs, including debt financing, due diligence and other costs related to transactions that are completed, pending or abandoned, that we believe are not representative of our ongoing business operations.


^(h)	Includes the impact of restructuring, integration and business optimization expenses which are incremental costs that are not representative of our ongoing business operations.

⁽ⁱ⁾

Represents adjustments for defined benefit pension plan costs in our statements of income. More than two-thirds of our defined benefit pension plan obligations are under defined benefit pension plans that are frozen, and the remaining obligations primarily relate to plans operated in certain of our non-U.S. locations that, pursuant to jurisdictional requirements, cannot be frozen. As such, we do not view such expenses as core to our ongoing business operations.

^(j)

Other costs consist of certain expenses that are not core to our ongoing business operations, including environmental remediation-related costs associated with the legacy operations of our business prior to the Business Combination, capital and franchise taxes, non-cash asset retirement obligation accretion and the initial implementation of procedures to comply with Section 404 of the Sarbanes-Oxley Act. Included in this line-item are rounding discrepancies that may arise from rounding from dollars (in thousands) to dollars (in millions).

Adjusted Net Income	$	17.5		$	20.9

⁽¹⁾

We define adjusted net income as net income attributable to PQ Group Holdings adjusted for non-operating income or expense and the impact of certain non-cash or other items that are included in net income that we do not consider indicative of our ongoing operating performance. Adjusted net income is presented as a key performance indicator as we believe it will enhance a prospective investor’s understanding of our results of operations and financial condition. Adjusted net income may not be comparable with net income or adjusted net income as defined by other companies.


⁽²⁾	Refer to the Adjusted EBITDA notes above for more information with respect to each adjustment.

⁽³⁾

Amount represents the impact to tax expense in net income before non-controlling interest and the related adjustments to net income associated with the Global Intangible Low Taxed Income (“GILTI”) provisions of the Tax Cuts and Jobs Act of 2017 (“TCJA”). Beginning January 1, 2018, GILTI results in taxation of “excess of foreign earnings,” which is defined as amounts greater than a 10% rate of return on applicable foreign tangible asset basis. The Company is required to record incremental tax provision impact with respect to GILTI as a result of having historical U.S. net operating loss (“NOL”) amounts to offset the GILTI taxable income inclusion. This NOL utilization precludes us from recognizing foreign tax credits (“FTCs”) which would

Table of Contents

otherwise help offset the tax impacts of GILTI. No FTCs will be recognized with respect to GILTI until our cumulative NOL balance has been exhausted. Because the GILTI provision does not impact our cash taxes (given available U.S. NOLs), and given that we expect to recognize FTCs to offset GILTI impacts once the NOLs are exhausted, we do not view this item as a component of core operations.

The adjustments to net income attributable to PQ Group Holdings Inc. are shown net of applicable tax rates of 36.5% and 30.6% for the three months ended March 31, 2019 and 2018 , respectively, except for the foreign currency exchange loss for which the tax is calculated as a discrete item using the applicable statutory income tax rates.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity consist of cash flow from operations, existing cash balances as well as funds available under our asset based lending revolving credit facility. We expect that ongoing requirements for debt service and capital expenditures will be funded from these sources of funds. Our primary liquidity requirements include funding working capital requirements (primarily inventory and accounts receivable, net of accounts payable and other accrued liabilities), debt service requirements and capital expenditures. Our capital expenditures include both maintenance of business, which include spending on maintenance and health, safety and environmental initiatives as well as growth, which includes spending to drive organic sales growth and cost savings initiatives.

We believe that our existing cash, cash equivalents and cash flows from operations, combined with availability under our asset based lending revolving credit facility, will be sufficient to meet our presently anticipated future cash needs for at least the next 12 months. We may also pursue strategic acquisition opportunities, which may impact our future cash requirements. We may, from time to time, increase borrowings under our asset based lending revolving credit facility to meet our future cash needs. As of March 31, 2019 , we had cash and cash equivalents of $52.3 million and availability of $170.2 million under our asset based lending revolving credit facility, after giving effect to $19.9 million of outstanding letters of credit and $2.0 million of revolving credit facility borrowings, for a total available liquidity of $222.5 million . As of March 31, 2019 , we were in compliance with all covenants under our debt agreements.

Included in our cash and cash equivalents balance as of March 31, 2019 was $40.7 million of cash and cash equivalents held in foreign jurisdictions. We repatriate cash held outside of the United States from certain foreign subsidiaries in order to meet domestic liquidity needs. Depending on domestic and foreign cash balances, we have certain flexibility to repatriate funds in order to meet those needs. Specifically, we have an intercompany loan structure in place with several of our foreign subsidiaries that allows us to repatriate foreign cash in a tax efficient manner from those subsidiaries. In certain cases, the repatriation of foreign cash under previous U.S. tax law had generally been subject to U.S. income taxes at the time of cash distribution. Due to the enactment of the TCJA in December 2017, future overseas earnings repatriation will generally no longer be subject to U.S. federal income taxes at the time of cash distribution. However, future foreign earnings may still be taxed for state income tax purposes, as well as subject to certain foreign withholding tax obligations, when cash amounts are distributed back to the U.S.

As of March 31, 2019 , our total indebtedness was $2,146.8 million , with up to $170.2 million of available borrowings under our asset based lending revolving credit facility. Our liquidity requirements are significant, primarily due to debt service requirements. As reported, our cash interest paid for the three months ended March 31, 2019 and 2018 was approximately $23.7 million and $16.6 million , respectively. Before any impact of hedges, a one percent change in assumed interest rates for our variable interest credit facilities would have an annual impact of approximately $11.7 million on interest expense.

Net cash provided by operating activities was $26.8 million for the three months ended March 31, 2019 , compared to $22.0 million provided for the three months ended March 31, 2018 . Cash generated by net income plus non-cash and non-working capital related activities was lower during the three months ended March 31, 2019 by $9.5 million compared to the same period in the prior year. The change in working capital during the three months ended March 31, 2019 was favorable compared to the three months ended March 31, 2018 . Cash used to fund working capital was $19.9 million and $34.8 million for the three months ended March 31, 2019 and 2018 , respectively.

Table of Contents

The decrease in cash generated by net income plus non-cash and non-working capital related activities of $9.5 million as compared to the prior year period was primarily due to lower dividends received from affiliated companies and net interest income on our cross currency swaps.

The increase in cash from working capital of $14.9 million as compared to the prior year was primarily due to favorable changes in accounts receivable, prepaid and other current assets and accounts payable, which was partially offset by unfavorable changes in accrued liabilities.

The favorable change in accounts receivable was due to lower Refining Services receivables related to customer plant outages. The favorable change in accounts payable was due to decreased levels of pending capital payments in accounts payable in the current year and the timing of plant maintenance costs in the prior year. The unfavorable change in accrued liabilities was primarily due to the timing of interest payments made under our new debt structure.

Net cash used in investing activities was $29.2 million for the three months ended March 31, 2019 , compared to cash used of $33.1 million during the same period in 2018 . Cash used in investing activities primarily consisted of utilizing $33.6 million and $33.3 million to fund capital expenditures during the three months ended March 31, 2019 and 2018 , respectively. During the three months ended March 31, 2019 , we received $3.9 million in interest proceeds related to our cross currency swaps.

Net cash used in financing activities was $2.5 million for the three months ended March 31, 2019 , compared to net cash provided of $5.4 million during the same period in 2018 . Net cash used in financing activities was primarily driven by $5.0 million in long-term debt repayments offset by $3.5 million of net borrowings under our revolving credit facilities made through the three months ended March 31, 2019 . Net cash provided by financing activities for the three months ended March 31, 2018 was mainly due to $6.5 million of net borrowings under our revolving credit facility partially offset by the net impact of the term loan refinancing (including debt issuance costs).

As of March 31, 2019 , our total debt was $2,146.8 million , including $15.5 million of other foreign debt and $51.8 million of notes payable for the New Market Tax Credit financing and excluding the original issue discount of $17.9 million and deferred financing fees of $15.1 million for our senior secured credit facilities and notes. Our net debt as of March 31, 2019 was $2,094.5 million including cash and cash equivalents of $52.3 million . We may seek, subject to market conditions and other factors, opportunities to repurchase, refinance or otherwise reprice our debt.

Capital Expenditures

Maintenance capital expenditures include spending on maintenance of business, health, safety and environmental initiatives. Growth capital expenditures include spending to drive organic sales growth and cost savings initiatives. These capital expenditures represent our “book” capital expenditures for which the company has recorded, but not necessarily paid for the capital expenditures.

Table of Contents

	(in millions)
Maintenance capital expenditures	$	18.5	$	20.6
Growth capital expenditures	6.7		4.7
Total capital expenditures	$	25.2	$	25.3

Capital expenditures remained at a level sufficient for required maintenance and certain expansion growth initiatives during these periods. Maintenance capital expenditures are lower in the three months ended March 31, 2019 as compared to the three months ended March 31, 2018 due to fewer plant maintenance projects incurred during the period. Growth capital expenditures are higher in the three months ended March 31, 2019 as compared to the three months ended March 31, 2018 due to increased spending to expand capacity at our production facilities.

Pension Funding

We paid $3.4 million in cash contributions into our defined benefit pension plans and other post-retirement plans during each of the three -month periods ended March 31, 2019 and 2018 . The net periodic pension expense was $1.2 million and $0.8 million for those same periods, respectively.

Off–Balance Sheet Arrangements

We had $19.9 million of outstanding letters of credit on our ABL Facility as of March 31, 2019 .

Contractual Obligations

Information related to our contractual obligations at December 31, 2018 can be found in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2018 , filed with the SEC on March 1, 2019, which we refer to as our Annual Report on Form 10-K. During the three months ended March 31, 2019 , there have been no significant changes to our contractual obligations as disclosed in our Annual Report on Form 10-K.

Critical Accounting Policies and Estimates

We prepare our condensed consolidated financial statements in conformity with GAAP and our significant accounting policies are described in Note 2 to our audited consolidated financial statements included in our Annual Report on Form 10-K. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts and related disclosures. We base our estimates and judgments on historical experience and other relevant factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We evaluate our critical accounting estimates, assumptions and judgments on an ongoing basis.

There has been no material change in our critical accounting policies and use of estimates from those described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in our Annual Report on Form 10-K.

Accounting Standards Not Yet Adopted

See Note 2 to our unaudited condensed consolidated financial statements for a discussion of recently issued accounting standards and their effect on us.


ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our major market risk exposure is potential losses arising from changing rates and prices regarding foreign currency exchange rate risk, interest rate risk, commodity price risk and credit risk. The audit committee of our board of directors regularly reviews foreign exchange, interest rate and commodity hedging activity and monitors compliance with our hedging policy. We do not use financial instruments for speculative purposes, and we limit our hedging activity to the underlying economic exposure.

There have been no material changes in the foreign exchange risk, interest rate risk, commodity risk or credit risk discussed in Item 7A., “Quantitative and Qualitative Disclosures about Market Risk,” included in our Annual Report on Form 10-K.

ITEM 4.	CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2019 , the end of the period covered by this Quarterly Report on Form 10-Q.

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

No changes in our internal control over financial reporting occurred during the quarter ended March 31, 2019 that materially affected, or which are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION


ITEM 1.	LEGAL PROCEEDINGS.

From time to time we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as personal injury, product liability and warranty claims, waste disposal practices, release of chemicals into the environment and other matters that may arise in the ordinary course of our business. We currently believe that there is no litigation pending that is likely to have a material adverse effect on our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.


ITEM 1A.	RISK FACTORS.

There has been no material change from the risk factors described in our Annual Report on Form 10-K.
