HARSCO CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1.     Basis of Presentation

Harsco Corporation (the "Company") has prepared these unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, the unaudited condensed consolidated financial statements do not include all information and disclosure required by U.S. GAAP for annual financial statements. The December 31, 2018 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2018 audited consolidated financial statements.  The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair statement are reflected in the unaudited condensed consolidated financial statements. 

Reclassifications

Certain reclassifications have been made to prior year amounts to conform with current year classifications.

2.     Recently Adopted and Recently Issued Accounting Standards

The following accounting standards have been adopted in 2019:

On January 1, 2019, the Company adopted changes issued by the Financial Accounting Standards Board (“FASB”) related to accounting for leases. The changes introduce a lessee model that brings most leases onto the balance sheet. The changes also align many of the underlying principles of the new lessor model with those in the FASB’s new revenue recognition standard. Furthermore, the changes address other concerns related to the current leases model such as eliminating the requirement in current guidance for an entity to use bright-line tests in determining lease classification. The changes also require lessors to increase the transparency of their exposure to changes in value of their residual assets and how they manage that exposure. The Company elected the package of practical expedients permitted under the transition, which among other items, allowed the carry forward of the historical lease classification. The Company has elected to apply the transition requirements at the January 1, 2019 effective date and therefore, comparative information has not been restated and continues to be reported under U.S. GAAP in effect for those periods. The changes had a significant impact on the Condensed Consolidated Balance Sheets upon adoption and the Company recorded Right-of-use ("ROU") assets and lease liabilities of $53.0 million and $53.4 million, respectively. The difference between the ROU assets and lease liabilities was recorded primarily as adjustments to other assets and liabilities where prepaid rent and deferred expenses were previously recorded. Additionally, the Company's accounting for finance leases remained consistent. The changes did not have an impact on the Company’s Condensed Consolidated Statements of Operations or Condensed Consolidated Statements of Cash Flows. The discount rates used to calculate the ROU assets and lease liabilities as of the effective date were based on the remaining lease terms as of the effective date. See Note 6, Leases for additional information.

On January 1, 2019, the Company adopted changes issued by the FASB which expand and refine hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedged items in the financial statements and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. Upon adoption, the Company’s recognition model for the excluded component was modified from a mark-to-market approach to an amortization approach for hedging relationships. Hedging relationships entered into on or after January 1, 2019 will be under the amortization approach while those entered into before

January 1, 2019 will continue to be recognized under the mark-to-market approach. As such, there was no effect of applying this election reflected as an adjustment to Accumulated other comprehensive loss with a corresponding adjustment to the opening balance of Retained earnings. Presentation and disclosure amendments are required to be applied prospectively. Other than required expanded disclosures, the adoption of these changes did not have a material impact on the Company's condensed consolidated financial statements.

8

On January 1, 2019, the Company adopted changes issued by the FASB which allow entities to reclassify stranded income tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings in the consolidated financial statements. Under the Tax Act, deferred taxes were adjusted to reflect the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate, which left the tax effects on items within accumulated other comprehensive income stranded at historical tax rates. The adoption of these changes resulted in the Company reclassifying approximately $21 million of stranded income tax effects into Retained earnings.

The following accounting standards have been issued and become effective for the Company at a future date:

In June 2016, the FASB issued changes which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The changes become effective for the Company on January 1, 2020, with early adoption permitted. Management has not yet completed the assessment of the impact of the new standard on the Company’s condensed consolidated financial statements.

In January 2017, the FASB issued changes that remove the second step of the annual goodwill impairment test, which requires a hypothetical purchase price allocation. The changes provide that the amount of goodwill impairment will be equal to the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. The changes become effective for the Company on January 1, 2020. Management has determined that these changes will not have a material impact on the Company's condensed consolidated financial statements. However, should the Company be required to record a goodwill impairment charge in future periods, the amount recorded may differ compared to any amounts that might be recorded under current practice.

In August 2018, the FASB issued changes which modify the disclosure requirements for fair value measurements. The amendments in this update remove the requirement to disclose the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level 3 fair value measurements. The changes require disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The changes become effective for the Company on January 1, 2020. Other than required expanded disclosures, the adoption of these changes will not have a material impact on the Company's condensed consolidated financial statements.

In August 2018, the FASB issued changes which modify the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The changes remove the requirements to disclose: amounts in accumulated other comprehensive income (loss) expected to be recognized as components of net periodic benefit cost over the next fiscal year; the amount and timing of plan assets expected to be returned to the employer; and the effects of a one-percentage point change in assumed health care cost trend rates. The update also requires disclosure of an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The changes become effective for the Company on January 1, 2021. Management does not believe these changes will have a material impact on its condensed consolidated financial statements.

3. Acquisitions

In May 2018, the Company acquired Altek Europe Holdings Limited and its affiliated entities (collectively, "Altek"), a U.K.-based manufacturer of market-leading products that enable aluminum producers and recyclers to manage and efficiently extract value from critical byproduct streams, reduce byproduct generation and improve operating productivity. The Company acquired Altek, on a debt and cash free basis, for a purchase price of £45 million (approximately $60 million) in cash, with the potential for up to £25 million (approximately $33 million) in additional contingent consideration through 2021 subject to the future financial performance of Altek. The cash consideration transferred included payments of $59.4 million, net of cash acquired and normal working capital adjustments. In addition, the Company recognized contingent consideration with an initial fair value of $12.1 million as of the acquisition date. Altek's revenues and operating results have been included in the results of the Harsco Metals & Minerals Segment. Inclusion of pro forma financial information for this transaction is not necessary as the acquisition is immaterial to the Company's results of operations.

9

The initial fair value of contingent consideration was estimated using a probability simulation model, which uses assumptions and estimates to forecast a range of outcomes for the contingent consideration. Key inputs to the model include projected earnings before interest, tax, depreciation and amortization; the discount rate; the projection risk neutralization rate; and volatility, which are Level 3 data.  The Company will assess these assumptions and estimates on a quarterly basis as additional data impacting the assumptions is obtained. Any changes in the fair value of contingent consideration related to updated assumptions and estimates will be recognized in the Consolidated Statements of Operations during the period in which the change occurs.

The fair value recorded for the assets acquired and liabilities assumed for Altek is as follows:

	Final Valuation
(In millions)	June 30 2018			Measurement Period Adjustments (a)		March 31 2019
Cash and cash equivalents	$	1.7		$	—	$	1.7
Net working capital	(1.5		)	0.2		(1.3		)
Property, plant and equipment	3.3			—		3.3
Intangible assets	52.5			0.2		52.7
Goodwill	20.9			1.6		22.5
Net deferred tax liabilities	(8.5		)	—		(8.5		)
Other liabilities	(0.3		)	—		(0.3		)
Total identifiable net assets of Altek	$	68.1		$	2.0	$	70.1

(a) The measurement period adjustments did not have a material impact on the Company's previously reported operating results.

The following table reflects the changes in the fair value of contingent consideration:

The Company recognized an initial estimated forward loss provision related to the contracts with the federal railway system of Switzerland ("SBB") of $45.1 million for the year ended December 31, 2016. The Company recorded an additional forward loss provision of $1.8 million for the year ended December 31, 2018. At March 31, 2019, the entire remaining estimated forward loss provision of $6.8 million is included in the caption Other current liabilities on the Condensed Consolidated Balance Sheets. The estimated forward loss provision represents the Company's best estimate based on currently available information. It is possible that the Company's overall estimate of costs to complete these contracts may increase, which would result in an additional estimated forward loss provision at such time, but the Company is unable to estimate any further possible loss or range of loss at this time. There are a number of key events expected to occur in 2019, including the finalization of the manufacturing designs for certain of the vehicles, and which could affect the cost estimates. Any adjustment to the cost estimates would be recorded when new information becomes available and could have a material impact on the Company’s results of operations in that period.

The Company recognized $4.7 million and $7.9 million of revenues for the contracts with SBB at zero margin, on an over time basis, utilizing a cost-to-cost method for the three months ended March 31, 2019 and 2018, respectively. For the three months ended March 31, 2019 and 2018, consolidated product revenue gross margins were not significantly impacted by the revenue recognized under the SBB contracts. The Company has substantially completed the first contract and is approximately 30% complete on the second contract with SBB as of March 31, 2019.

6. Leases

The Company leases certain property and equipment under noncancelable lease agreements. The Company determines if a contract or arrangement contains a lease at inception. All leases are evaluated and classified as either an operating or finance lease. A lease is classified as a finance lease if any of the following criteria are met: (i) ownership of the underlying asset transfers to the Company by the end of the lease term; (ii) the lease contains an option to purchase the underlying asset that the Company is reasonably expected to exercise; (iii) the lease term is for a major part of the remaining economic life of the underlying asset; (iv) the present value of the sum of lease payments and any residual value guaranteed by the Company equals or exceeds substantially all of the fair value of the underlying asset; or (v) the underlying asset is of a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. A lease that does not meet any of the criteria to be classified as a finance lease is classified as an operating lease.

11

Operating leases are included in the captions Right-of-use assets, net, Current portion of operating lease liabilities, and Operating lease liabilities on the Condensed Consolidated Balance Sheets. ROU assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. As most of the Company’s leases do not provide an implicit rate for use in determining the present value of future payments, the Company uses an incremental borrowing rate that reflects the creditworthiness of the Company for a lending period commensurate to the term of the lease and the standard lending practices related to such loans in the respective jurisdiction where the underlying assets are located. This incremental borrowing rate reflects the creditworthiness of the Company for a lending period commensurate to the term of the lease and the standard lending practices related to such loans in the respective jurisdiction where the underlying assets are located. ROU assets also include any lease payments made and exclude any lease incentives and initial direct costs incurred. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term, including rent abatement periods and rent holidays.

Finance leases are included in the captions Property, plant and equipment, net; Current maturities of long-term debt and Long-term debt on the Condensed Consolidated Balance Sheets. Finance lease costs are split between depreciation expense related to the asset and interest expense on the lease liability, using the effective rate charged by the lessor.

The Company has lease agreements with lease and non-lease components, which the Company has elected to account for as a single lease component. Additionally, the Company has elected not to record short-term leases, those with expected terms of twelve months or less, on the Condensed Consolidated Balance Sheets. Certain lease agreements include fixed escalations, while others include rental payments adjusted periodically for inflation. There are no material residual value guarantees or material restrictive covenants. The Company's leases, excluding short-term leases, have remaining terms of less than one year to 24.5 years, some of which include options to extend for up to 10 years, and some of which include options to terminate within one year.

The Company's estimate of expected contributions to be paid during the remainder of 2019 for the U.S. and international defined benefit pension plans are $7.0 million and $11.5 million, respectively.

9.     Income Taxes 

Income tax expense related to continuing operations for the three months ended March 31, 2019 and March 31, 2018 was $4.9 million and $8.3 million, respectively.

An income tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, based on technical merits, including resolutions of any related appeals or litigation processes. The reserve for uncertain tax positions at March 31, 2019 was $3.5 million, including interest and penalties.  Within the next twelve months, it is reasonably possible that up to $0.1 million of unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.

10.   Commitments and Contingencies

Environmental        

The Company is involved in a number of environmental remediation investigations and cleanups and, along with other companies, has been identified as a “potentially responsible party” for certain byproduct disposal sites.  While each of these matters is subject to various uncertainties, it is probable that the Company will agree to make payments toward funding certain of these activities, and it is possible that some of these matters will be decided unfavorably to the Company.  The Company has evaluated its potential liability, and its financial exposure is dependent upon such factors as the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the allocation of cost among potentially responsible parties, the years of remedial activity required and the remediation methods selected.  Other than set forth herein the Company did not have any material accruals or record any material expenses related to environmental matters during the periods presented.

The Company evaluates its liability for future environmental remediation costs on a quarterly basis. Although actual costs to be incurred at identified sites in future periods may vary from the estimates (given inherent uncertainties in evaluating environmental exposures), the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with environmental matters in excess of the amounts accrued would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

As previously disclosed, the Company has had ongoing meetings with the Supreme Council for Environment in Bahrain (“SCE”) over processing a byproduct (“salt cakes”) stored at the Al Hafeerah site. The Company’s Bahrain operations that produced the salt cakes has ceased operations and are owned under a strategic venture for which its strategic venture partner owns a 35% minority interest. An Environmental Impact Assessment and Technical Feasibility Study were approved by the SCE during the first quarter of 2018. The Company has previously established a reserve of $7.0 million, which represents the Company's best estimate of the ultimate costs to be incurred to resolve this matter. The Company continues to evaluate this reserve and any future change in estimated costs could be material to the Company’s results of operations in any one period.

On July 27, 2018, Brazil’s Federal and Rio de Janeiro State Public Prosecution Offices (MPF and MPE) filed a Civil Public Action against one of the Company's customers (CSN), the Company’s Brazilian subsidiary, the Municipality of Volta Redonda, Brazil, and the Instituto Estadual do Ambiente (local environmental protection agency) seeking the implementation of various measures to limit and reduce the accumulation of customer-owned slag at the site in Brazil. On August 6, 2018, the 3rd Federal Court in Volta Redonda granted the MPF and MPE an injunction against the same parties requiring, among other things, CSN and the Company’s Brazilian subsidiary to limit the volume of slag sent to the site. Because the customer owns the site and the slag located on the site, the Company believes that complying with this injunction is the steel producer’s responsibility.  On March 18, 2019, the Court issued an order fining the Company 5,000 Brazilian real per day (or approximately $1,300 per day) and CSN 20,000 Brazilian real per day until the requirements of the injunction are met. This fine is not yet currently being enforced, and the Company is appealing the fine and the underlying injunction.  Both the Company and CSN continue to have discussions with the governmental authorities on the injunction and the possible resolution of the underlying case. The Company does not believe that a loss relating to this matter is probable or estimable at this point.

On October 19, 2018, local environmental authorities issued an enforcement action against the Company concerning the Company’s operations at a customer site in Ijmuiden, Netherlands.  The enforcement action alleges violations of the Company’s environmental permit at the site, which restricts the release of any visible dust emissions.  The enforcement action ordered the Company to cease all violations of the permit by October 31, 2018.  The authorities have issued fines of approximately $0.3 million, with the possibility of additional fines for any future violations.  The Company is vigorously contesting the enforcement action and fines and is also working with its customer to ensure the control of emissions.  The Company has contractual indemnity rights from its customer, should it be required to pay the assessed fines. 

Brazilian Tax Disputes

The Company is involved in a number of tax disputes with federal, state and municipal tax authorities in Brazil. These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest charges that increase at statutorily determined amounts per month and are assessed on the aggregate amount of the principal and penalties. In addition, the losing party, at the collection action or court of appeals phase, could be subject to a charge to cover statutorily mandated legal fees, which are generally calculated as a percentage of the total assessed amounts due, inclusive of penalty and interest. Many of the claims relate to value-added ("ICMS"), services and social security tax disputes. The largest proportion of the assessed amounts relate to ICMS claims filed by the State Revenue Authorities from the State of São Paulo, Brazil (the "SPRA"), encompassing the period from January 2002 to May 2005.

In October 2009, the Company received notification of the SPRA’s final administrative decision regarding the levying of ICMS in the State of São Paulo in relation to services provided to a customer in the State between January 2004 and May 2005.  As of March 31, 2019, the principal amount of the tax assessment from the SPRA with regard to this case is approximately $2 million, with penalty, interest and fees assessed to date increasing such amount by an additional $21 million.  On

June 4, 2018, the Appellate Court of the State of Sao Paulo ruled in favor of the SPRA, but ruled that the assessed penalty should be reduced to approximately $2 million. After calculating the interest accrued on the penalty, the Company estimates that this ruling reduces the current overall liability for this case to approximately $9 million. The Company has appealed the ruling in favor of the SPRA to the Superior Court of Justice. Due to multiple court precedents in the Company’s favor, as well as the Company’s ability to appeal, the Company does not believe a loss is probable.

Another ICMS tax case involving the SPRA refers to the tax period from January 2002 to December 2003. In December 2018, the administrative tribunal hearing the case upheld the Company's liability. The Company plans to appeal to the judicial phase. The aggregate amount assessed by the tax authorities in August 2005 was $6.5 million (the amounts with regard to this claim are valued as of the date of the assessment since it has not yet reached the collection phase), composed of a principal amount of $1.5 million, with penalty and interest assessed through that date increasing such amount by an additional $4.9 million.  On December 6, 2018, the administrative tribunal reduced the applicable penalties to $1.2 million. After calculating the interest accrued on the current penalty, the Company estimates that this ruling reduces the current overall liability for this case to approximately $10 million. All such amounts include the effect of foreign currency translation. Due to multiple court precedents in the Company's favor the Company does not believe a loss is probable.

The Company continues to believe that sufficient coverage for these claims exists as a result of the indemnification obligations of the Company's customer and such customer’s pledge of assets in connection with the October 2009 notice, as required by Brazilian law.

16

The Company intends to continue its practice of vigorously defending itself against these tax claims under various alternatives, including judicial appeal. The Company will continue to evaluate its potential liability with regard to these claims on a quarterly basis; however, it is not possible to predict the ultimate outcome of these tax-related disputes in Brazil. No loss provision has been recorded in the Company's condensed consolidated financial statements for the disputes described above because the loss contingency is not deemed probable, and the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with Brazilian tax disputes would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Brazilian Labor Disputes

The Company is subject to ongoing collective bargaining and individual labor claims in Brazil through the Harsco Metals & Minerals Segment which allege, among other things, the Company's failure to pay required amounts for overtime and vacation at certain sites. The Company is vigorously defending itself against these claims; however, litigation is inherently unpredictable, particularly in foreign jurisdictions. While the Company does not currently expect that the ultimate resolution of these claims will have a material adverse effect on the Company’s financial condition, results of operations or cash flows, it is not possible to predict the ultimate outcome of these labor-related disputes. As of March 31, 2019 and December 31, 2018, the Company has established reserves of $7.0 million and $7.1 million, respectively, on the Company's Condensed Consolidated Balance Sheets for amounts considered to be probable and estimable.

Customer Disputes

The Company may, in the normal course of business, become involved in commercial disputes with subcontractors or customers. Although results of operations and cash flows for a given period could be adversely affected by a negative outcome in these or other lawsuits, claims or proceedings, management believes that the ultimate outcome of any ongoing matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Lima Refinery Litigation

On April 8, 2016, Lima Refining Company filed a lawsuit against the Company in the District Court of Harris County, Texas related to a January 2015 explosion at an oil refinery operated by Lima Refining Company. The action seeks approximately $317 million plus interest in property damages, lost profits and business interruption damages. The action alleges the explosion occurred because of a defect in a heat exchange cooler manufactured by Hammco Corporation ("Hammco") in 2009, prior to the Company’s acquisition of Hammco in 2014. The Company is vigorously contesting the allegations against it. The Company has both an indemnity right from the sellers of Hammco and liability insurance coverage under various primary and excess policies that the Company believes will be available, if necessary, to cover substantially all such liability that might ultimately be incurred in the above action. As a result, the Company believes the situation will not result in a net unreimbursed loss.

Other

The Company is named as one of many defendants (approximately 90 or more in most cases) in legal actions in the U.S. alleging personal injury from exposure to airborne asbestos over the past several decades.  In their suits, the plaintiffs have named as defendants, among others, many manufacturers, distributors and installers of numerous types of equipment or products that allegedly contained asbestos.

The Company believes that the claims against it are without merit. The Company has never been a producer, manufacturer or processor of asbestos fibers. Any asbestos-containing part of a Company product used in the past was purchased from a supplier and the asbestos encapsulated in other materials such that airborne exposure, if it occurred, was not harmful and is not associated with the types of injuries alleged in the pending actions.

At March 31, 2019, there were approximately 17,127 pending asbestos personal injury actions filed against the Company.  Of those actions, approximately 16,586 were filed in the New York Supreme Court (New York County), approximately 119 were filed in other New York State Supreme Court Counties and approximately 422 were filed in courts located in other states.

The complaints in most of those actions generally follow a form that contains a standard damages demand of $20 million or $25 million, regardless of the individual plaintiff’s alleged medical condition, and without identifying any specific Company product.

At March 31, 2019, approximately 16,550 of the actions filed in New York Supreme Court (New York County) were on the Deferred/Inactive Docket created by the court in December 2002 for all pending and future asbestos actions filed by persons who cannot demonstrate that they have a malignant condition or discernible physical impairment. The remaining approximately 36 cases in New York County are pending on the Active or In Extremis Docket created for plaintiffs who can demonstrate a malignant condition or physical impairment.

17

The Company has liability insurance coverage under various primary and excess policies that the Company believes will be available, if necessary, to substantially cover any liability that might ultimately be incurred in the asbestos actions referred to above. The costs and expenses of the asbestos actions are being paid by the Company's insurers.

In view of the persistence of asbestos litigation in the U.S., the Company expects to continue to receive additional claims in the future. The Company intends to continue its practice of vigorously defending these claims and cases. At March 31, 2019, the Company has obtained dismissal in approximately 28,189 cases by stipulation or summary judgment prior to trial.

It is not possible to predict the ultimate outcome of asbestos-related actions in the U.S. due to the unpredictable nature of this litigation, and no loss provision has been recorded in the Company's condensed consolidated financial statements because a loss contingency is not deemed probable or estimable. Despite this uncertainty, and although results of operations and cash flows for a given period could be adversely affected by asbestos-related actions, the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with asbestos litigation would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

The Company is subject to various other claims and legal proceedings covering a wide range of matters that arose in the ordinary course of business. In the opinion of management, all such matters are adequately covered by insurance or by established reserves, and, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Insurance liabilities are recorded when it is probable that a liability has been incurred for a particular event and the amount of loss associated with the event can be reasonably estimated. Insurance reserves have been estimated based primarily upon actuarial calculations and reflect the undiscounted estimated liabilities for ultimate losses, including claims incurred but not reported. Inherent in these estimates are assumptions that are based on the Company's history of claims and losses, a detailed analysis of existing claims with respect to potential value, and current legal and legislative trends. If actual claims differ from those projected by management, changes (either increases or decreases) to insurance reserves may be required and would be recorded through income in the period the change was determined. When a recognized liability is covered by third-party insurance, the Company records an insurance claim receivable to reflect the covered liability. Insurance claim receivables are included in Other receivables on the Company's Condensed Consolidated Balance Sheets. See Note 1, Summary of Significant Accounting Policies, to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 for additional information on Accrued insurance and loss reserves.

12.   Derivative Instruments, Hedging Activities and Fair Value

Derivative Instruments and Hedging Activities

The Company uses derivative instruments, including foreign currency exchange forward contracts, interest rate swaps and cross-currency interest rate swaps ("CCIRs"), to manage certain foreign currency and interest rate exposures.  Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes. All derivative instruments are recorded on the Condensed Consolidated Balance Sheets at fair value.  The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price).  The Company utilizes market data or assumptions that the Company believes market participants would use in valuing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique.

The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (2) an entity’s own assumptions about market participant assumptions based on the best information available in the circumstances (unobservable inputs).  The fair value hierarchy consists of three broad levels, which give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). 

The three levels of the fair value hierarchy are described below:

• Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3—Inputs that are both significant to the fair value measurement and unobservable. 

In instances in which multiple levels of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the fair value measurement in its entirety.  The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information.  Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs, such as forward rates, interest rates, the Company’s credit risk and counterparties’ credit risks, and which minimize the use of unobservable inputs.  The Company is able to classify fair value balances based on the ability to observe those inputs.  Foreign currency exchange forward contracts, interest rate swaps and CCIRs are based upon pricing models using market-based inputs (Level 2).  Model inputs can be verified and valuation techniques do not involve significant management judgment.

All of the Company's derivatives are recorded on the Condensed Consolidated Balance Sheets at gross amounts and not offset. All of the Company's interest rate swaps, CCIRs and certain foreign currency exchange forward contracts are transacted under International Swaps and Derivatives Association ("ISDA") documentation. Each ISDA master agreement permits the net settlement of amounts owed in the event of default. The Company's derivative assets and liabilities subject to enforceable master netting arrangements resulted in a net liability of $1.0 million and $0.1 million at March 31, 2019 and

December 31, 2018, respectively.

(c)  These gains (losses) offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

Foreign Currency Exchange Forward Contracts

The Company conducts business in multiple currencies and, accordingly, is subject to the inherent risks associated with foreign exchange rate movements.  Foreign currency-denominated assets and liabilities are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods. 

The Company uses derivative instruments to hedge cash flows related to foreign currency fluctuations.  Foreign currency exchange forward contracts outstanding are part of a worldwide program to minimize foreign currency exchange operating income and balance sheet exposure by offsetting foreign currency exposures of certain future payments between the Company and various subsidiaries, suppliers or customers.  The unsecured contracts are with major financial institutions.  The Company may be exposed to credit loss in the event of non-performance by the contract counterparties.  The Company evaluates the creditworthiness of the counterparties and does not expect default by them.  Foreign currency exchange forward contracts are used to hedge commitments, such as foreign currency debt, firm purchase commitments and foreign currency cash flows for certain export sales transactions.

Changes in the fair value of derivatives used to hedge foreign currency denominated balance sheet items are reported directly in earnings, along with offsetting transaction gains and losses on the items being hedged.  Derivatives used to hedge forecasted cash flows associated with foreign currency commitments may be accounted for as cash flow hedges, as deemed appropriate, if the criteria for hedge accounting are met.  Gains and losses on derivatives designated as cash flow hedges are deferred in Accumulated other comprehensive loss, a separate component of equity, and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions.  The ineffective portion of all hedges, if any, is recognized currently in earnings.

The recognized gains and losses offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures. At March 31, 2019 and December 31, 2018, the notional amounts of foreign currency exchange forward contracts were $444.3 million and $423.9 million, respectively. These contracts are primarily denominated in British pounds sterling and Euros and mature through October 2021.

21

In addition to foreign currency exchange forward contracts, the Company designates certain loans as hedges of net investments in international subsidiaries.  The Company recorded pre-tax net gains of $4.8 million and $9.5 million for the three months ended March 31, 2019 and March 31, 2018, respectively, in Accumulated other comprehensive loss.

Interest Rate Swaps

The Company uses interest rate swaps in conjunction with certain debt issuances in order to secure a fixed interest rate.  Changes in the fair value attributed to the effect of the swaps’ interest spread and changes in the credit worthiness of the counter-parties are recorded in Accumulated other comprehensive loss. 

In January 2017 and February 2018, the Company entered into a series of interest rate swaps that cover the period from 2018 through 2022 and had the effect of converting $300.0 million of the Term Loan Facility from floating-rate to fixed-rate.  The fixed rates provided by the swaps replace the adjusted LIBOR rate in the interest calculation, ranging from 2.12% for 2019 to 3.12% for 2022. The total notional of the Company's interest rate swaps was $300.0 million as of March 31, 2019.

Cross-Currency Interest Rate Swaps

The Company may use CCIRs in conjunction with certain debt issuances in order to secure a fixed local currency interest rate. Under these CCIRs, the Company receives interest based on a fixed or floating U.S. dollar rate and pays interest on a fixed local currency rate based on the contractual amounts in dollars and the local currency, respectively. At maturity, there is also the payment of principal amounts between currencies. Changes in the fair value attributed to the effect of the swaps' interest spread and changes in the credit worthiness of the counter-parties are recorded in Accumulated other comprehensive loss. Changes in value attributed to the effect of foreign currency fluctuations are recorded in the Condensed Consolidated Statements of Operations and offset currency fluctuation effects on the debt principal. The Company had no outstanding CCIRs at March 31, 2019.

Fair Value of Other Financial Instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and short-term borrowings approximate fair value due to the short-term maturities of these assets and liabilities.  At March 31, 2019 and December 31, 2018, the total fair value of long-term debt (excluding deferred financing costs), including current maturities, was $657.4 million and $592.0 million, respectively, compared with a carrying value of $661.5 million and $605.4 million, respectively.  Fair values for debt are based on pricing models using market-based inputs (Level 2) for similar issues or on the current rates offered to the Company for debt of the same remaining maturities.

(a) Revenues are attributed to individual countries based on the location of the facility generating the revenue.

(b) Includes Mexico.

The Company may receive payments in advance of earning revenue, which are treated as Advances on contracts on the Condensed Consolidated Balance Sheets. The Company may recognize revenue in advance of being able to contractually invoice the customer, which is treated as Contract assets on the Condensed Consolidated Balance Sheets. Contract assets are transferred to Trade accounts receivable, net when right to payment becomes unconditional. Contract assets and Contract liabilities are reported as a net position, on a contract-by-contract basis, at the end of each reporting period. These instances are primarily related to the Harsco Rail Segment and air-cooled heat exchangers business of the Harsco Industrial Segment.

The Company had Contract assets totaling $17.5 million and $24.3 million at March 31, 2019 and December 31, 2018, respectively. The decrease is due principally to the transfer of contract assets to accounts receivable in excess of additional contract assets recognized during the three months ended March 31, 2019, primarily in the Harsco Rail Segment. The Company had Advances on contracts totaling $64.5 million and $69.0 million at March 31, 2019 and December 31, 2018, respectively. The decrease is due principally to the recognition of revenue on previously received advances on contracts in excess of receipts of new advances on contracts during the period and the impact of foreign currency translation during the three months ended March 31, 2019, primarily in the Harsco Rail Segment. During the three months ended March 31, 2019, the Company recognized $21.5 million of revenue related to amounts included in Advances on contracts at December 31, 2018.

At March 31, 2019, the Harsco Metals & Minerals Segment had remaining, fixed, unsatisfied performance obligations, where the expected contract duration exceeds one year totaling $136.7 million. Of this amount, $43.6 million is expected to be fulfilled by March 31, 2020, $35.4 million by March 31, 2021, $24.9 million by March 31, 2022, $22.9 million by

March 31, 2023 and the remainder thereafter. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year. The decrease from December 31, 2018 is primarily due to changes in foreign currency exchange rates.

At March 31, 2019, the Harsco Rail Segment had remaining, fixed, unsatisfied performance obligations, where the expected contract duration exceeds one year totaling $209.8 million. Of this amount, $94.3 million is expected to be fulfilled by March 31, 2020, $64.5 million by March 31, 2021, $36.7 million by March 31, 2022, $14.2 million by March 31, 2023 and the remainder thereafter. These amounts exclude any variable fees, fixed fees subject to indexation and any performance obligations expected to be satisfied within one year.

17. Subsequent Events

On May 9, 2019 the Company announced two separate strategic transactions that accelerate the transformation of the Company’s portfolio of businesses into a leading provider of environmental solutions and aligns with the Company’s strategy to decrease the complexity of the Company’s business portfolio by focusing on less cyclical and higher-growth businesses.

The Company has entered into a definitive agreement to acquire CEHI Acquisition Corporation and Subsidiaries (“Clean Earth”), a leader in processing special waste and hazardous and non-hazardous waste, from Compass Diversified Holdings for approximately $625 million in cash, subject to post-closing adjustments. The transaction has been approved by the Company's Board of Directors ("Board") and is expected to close during the next few months, subject to customary closing conditions, including receipt of certain regulatory approvals. There are no material financial or other contingencies to close the transaction.

In addition, the Company has entered into a definitive agreement to sell the Harsco Industrial Air-X-Changers business to Chart Industries, Inc. for $592 million in cash, subject to post-closing adjustments. The transaction has been approved by the Company's Board and is expected to close during the next few months, subject to customary closing conditions, including receipt of certain regulatory approvals. There are no material financial or other contingencies to close the transaction.

The Company has received bank financing commitments for the purchase of Clean Earth and plans to pursue long-term, unsecured debt financing as well as the upsize and extension of the Company's revolving credit facility. The proceeds from the sale of the Harsco Industrial Air-X-Changers business will be used to reduce borrowings under the existing Senior Secured Credit Facility and support further investment in the core environmental solutions business and the Harsco Rail Segment.

Executive Overview

The Company is a diversified, multinational provider of industrial services and engineered products serving global industries that are fundamental to worldwide economic growth and infrastructure development. The Company's operations consist of three reportable segments: Harsco Metals & Minerals, Harsco Industrial and Harsco Rail. In general, each of the Company’s segments are among the market leaders in their respective sectors. The Harsco Metals & Minerals Segment operates primarily under long-term contracts, providing critical services and support to the steelmaking process; and environmental and zero waste solutions for manufacturing by-products within the metals industry. The Harsco Industrial Segment is a supplier of custom-engineered and manufactured air-cooled heat exchangers that support the processing and distribution of natural gas and downstream refined products; manufactures a full range of metal bar grating configurations, used mainly in industrial flooring, as well as safety and security applications; and also manufactures energy-efficient heat transfer products such as boilers and water heaters, for various commercial and industrial applications. The Harsco Rail Segment is a provider of highly engineered maintenance equipment, after-market parts and safety and diagnostic systems which support railroad and transit customers worldwide. The Company has locations in approximately 30 countries, including the U.S. The Company was incorporated in 1956.

Highlights from the first quarter 2019 included (refer to the discussion of segment and consolidated results included within Results of Operations below, as well as Liquidity and Capital Resources, for additional information pertaining to the key drivers impacting these highlights):

• Revenues for the first quarter of 2019 increased approximately 10% compared with the first quarter of 2018. The primary drivers for this increase were strong demand in the Harsco Industrial Segment's air-cooled heat exchangers business and increased maintenance of way equipment sales in the Harsco Rail Segment.

• Operating income from continuing operations for the first quarter of 2019 increased approximately 5% compared with the first quarter of 2018. The primary driver for this increase was improved operating results in the Harsco Industrial and Harsco Rail Segments. These improvements were partially offset by modestly lower operating results in the Harsco Metals & Minerals Segment primarily due to increased selling, general and administrative costs to support the Company's strategic growth initiatives and the impact of foreign currency translation. Additionally, Corporate costs increased during the first quarter of 2019 compared to the same period in prior year to support the Company's strategic initiatives such as the acquisition of Clean Earth, a leader in processing special waste and hazardous and non-hazardous waste, and the sale of the Harsco Industrial Air-X-Changers business as announced on May 9, 2019. See Note 17, Subsequent Events, in Part I, Item 1, “Financial Statements,” for additional information.

• Diluted earnings per common share from continuing operations attributable to Harsco Corporation for the first quarter of 2019 were $0.26, an increase of approximately 18% compared with the first quarter of 2018. The primary drivers for the increase were improved operating results and a decrease in income tax expense. As anticipated, these factors were partially offset by increased defined benefit pension expense.

• Cash flows from operating activities for the first quarter of 2019 were $14.8 million, an increase of $23.1 million compared with the first quarter of 2018. The primary driver for this increase was a favorable change in working capital.

Looking forward, the Company maintains a positive outlook across all businesses. The Company’s view for the remainder of 2019 and beyond is supported by the below factors, which should be considered in the context of other risks, trends and strategies in the Company's Annual Report on Form 10-K for the year ended December 31, 2018:

• Customers served by the Harsco Metals & Minerals Segment have benefited from recent improvements in global steel production. For 2019, (i) global growth in steel production and consumption are expected to increase demand for mill services; (ii) new site (contract) contributions are expected to outpace site exits; and (iii) continued operational savings are expected to improve operating results compared to 2018. Additionally, revenues for 2019 will be positively impacted by demand for aluminum dross and scrap processing systems and the inclusion of a full year of results for Altek.

• The Harsco Industrial Segment’s air-cooled heat exchangers business continues to be positively impacted by fundamental improvements within energy markets. Bookings for this business have increased significantly over the past year. For 2019, (i) the air-cooled heat exchangers business continues to maintain a robust backlog, (ii) improved demand is anticipated across this Segment's product offerings as the result of increased capital spending in end markets; and (iii) new product offerings are expected to positively impact operating results.

29

• The Harsco Rail Segment has experienced continued improvement in demand for maintenance of way equipment from North American railroads following a period of decreased demand in recent years. Harsco Rail has also benefited from continued growth, market penetration and investment in foreign markets to increase international equipment sales as well as after-market parts and Protran Technology. As a result, this Segment began 2019 with strong backlog. Additionally, the Harsco Rail Segment has undertaken a number of strategic actions over the past two years to improve manufacturing processes. As previously disclosed, the Company began to consolidate and centralize North American manufacturing and distribution into one facility, allowing for improved efficiency and better service to customers. The capital investment to complete this program and other expenditures will continue through 2019. The annualized savings anticipated from this latest action are approximately $7 million, with a portion of these benefits expected to materialize in the second-half of 2019. The net impact of such costs and savings will not have a significant impact on 2019 operating results.

• The Company anticipates higher selling, general and administrative costs across all Segments as well as increased research and development spending in the Harsco Rail Segment, necessary to support anticipated volume increases and the Company's strategic growth initiatives.

• Net periodic pension cost ("NPPC") will increase by approximately $9 million during 2019, which will primarily be reflected in the caption Defined benefit pension (income) expense on the consolidated statement of operations. The increase is primarily the result of lower plan assets at December 31, 2018.

• The Company anticipates that corporate spending will increase in 2019 in order to support the Company's strategic growth initiatives.

Factors Positively Affecting Operating Income:

• Overall, steel production by customers under services contracts, including the impact of new and exited contracts increased modestly for the first quarter of 2019 compared with the same period in the prior year.

• Operating income was positively affected by a $2.3 million gain during the first quarter of 2019 related to the recognition of a foreign currency cumulative translation adjustment resulting from the substantial liquidation of a subsidiary.

Factors Negatively Impacting Operating Income:

• Operating results for the first quarter of 2019 were negatively impacted by decreased profitability in the Company's nickel-related sites partially due to decreased nickel prices. Nickel prices decreased 13% for the first quarter of 2019 compared with the same period in prior year.

• Higher operating costs in the industrial abrasives and roofing granules business.

• Operating results for the first quarter of 2019 were also negatively impacted by costs associated with the continued integration and scaling of the aluminum dross and scrap processing systems business acquired during 2018 including increased amortization expenses associated with intangible assets recognized as part of the acquisition.

• Higher selling, general and administrative costs due to higher compensation expense to support and execute the Company's growth strategies.

• Foreign currency translation decreased operating income by $1.6 million for the first quarter of 2019 compared with the same period in prior year.

• A favorable mix and increased demand for after-market part sales increased operating income during the first quarter of 2019 compared with the same period in the prior year.

• Results for the first quarter of 2018 included an additional forward contract loss provision related to the Company's first of two contracts with the federal railway system of Switzerland of $1.8 million resulting from incurring actual costs to complete in excess of originally estimated costs.

31

Factors Negatively Impacting Operating Income:

• Lower contract service volumes decreased operating income in the first quarter of 2019 compared with the same period in prior.

• Increased selling, general and administrative expenses for the first quarter of 2019 primarily related to higher compensation expense to support and execute the Company's growth strategy.

Comparative Analysis of Consolidated Results

Revenues

Revenues for the first quarter of 2019 increased $39.3 million or 9.6% from the first quarter of 2018. Foreign currency translation decreased revenues by approximately $18 million for the first quarter of 2019 compared with the same period in the prior year. Refer to the discussion of segment results above for information pertaining to factors positively affecting and negatively impacting revenues.

Cost of Services and Products Sold

Cost of services and products sold for the first quarter of 2019 increased $27.5 million or 8.8% from the first quarter of 2018. The changes in cost of services and products sold was attributable to the following significant items:

	March 31, 2019
(In millions)	Three Months Ended
Increased costs due to changes in revenues (exclusive of the effects of foreign currency translation and including fluctuations in commodity costs included in selling prices).	$	42.7
Impact of foreign currency translation.	(14.6		)
Other.	(0.6		)
Total change in cost of services and products sold — 2019 vs. 2018	$	27.5

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the first quarter of 2019 increased $9.9 million or 17.4% from the first quarter of 2018. This increase was primarily related to higher compensation expense and professional fees needed to support personnel investment and execute the Company's growth strategy; the inclusion of selling, general and administrative expenses associated with the Altek acquisition which occurred in May 2018; and increased external sales commissions primarily in the Company's air-cooled heat exchange business; partially offset by the impact of foreign currency translation.

Contingent consideration adjustments	369			—
Net gains	(2,271		)	—
Other	(199		)	6
Other expenses, net	$	1,876		$	1,822

Interest Expense

Interest expense during the first quarter of 2019 increased $0.2 million compared with the first quarter of 2018. The increase primarily relates to modestly higher borrowings under the Company's Senior Secured Credit Facility.

Defined Benefit Pension Income (Expense)

Defined benefit pension expense for the first quarter of 2019 was $1.3 million, compared with defined benefit pension income of $0.8 million for the first quarter of 2018. The change is primarily the result of lower plan assets at December 31, 2018.

Income Tax Expense

Income tax expense related to continuing operations for the first quarter of 2019 was $4.9 million, compared with $8.3 million for the first quarter of 2018. Income tax expense decreased primarily due to the income tax benefit recognized for stock-based compensation which vested during the first quarter of 2019.

Income from Continuing Operations

Income from continuing operations was $22.9 million in the first quarter of 2019, compared with $20.0 million in the first quarter of 2018. The primary driver for these increases was improved operating results in the Harsco Industrial and Harsco Rail Segments; and a decrease in income tax expense; partially offset by increased defined benefit pension expense.

Total Other Comprehensive Income

Total other comprehensive income was $4.5 million in the first quarter of 2019, compared with total other comprehensive income of $6.2 million in the first quarter of 2018. The primary drivers of this decrease were unrealized cash flow hedge losses for the three months ended March 31, 2019 compared to unrealized cash flow hedge gains for the same period in the prior year, partially offset by the net favorable impact of foreign currency translation due to the weakinging of the U.S. dollar against certain currencies during the first three months of 2019 including foreign currency translation of cumulative unrecognized actuarial losses on the Company's pension obligations.

33

Liquidity and Capital Resources

Cash Flow Summary

The Company has sufficient financial liquidity and borrowing capacity to support the strategies within each of its businesses.  The Company currently expects operational and business needs to be met by cash provided by operations supplemented with borrowings from time to time due to historical patterns of seasonal cash flow and for the funding of various projects. The Company regularly assesses capital needs in the context of operational trends and strategic initiatives.

The Company’s cash flows from operating, investing and financing activities, as reflected in the Condensed Consolidated Statements of Cash Flows, are summarized in the following table:

	Three Months Ended
	March 31
(In millions)	2019			2018
Net cash provided (used) by:
Operating activities	$	14.8		$	(8.2	)
Investing activities	(38.6		)	(30.3		)
Financing activities	44.4			39.2
Effect of exchange rate changes on cash and cash equivalents, including restricted cash	—			0.7
Net change in cash and cash equivalents, including restricted cash	$	20.5		$	1.3

 

Net cash provided (used) by operating activities — Net cash provided by operating activities in the first three months of 2019 was $14.8 million, an increase of $23.1 million from net cash used by operating activities in the first three months of 2018.  The increase is primarily attributable to customer receipts in the Harsco Rail Segment and lower accrued compensation payments compared to the same period prior year.

Net cash used by investing activities — Net cash used by investing activities in the first three months of 2019 was $38.6 million, an increase of $8.3 million from the net cash used by investing activities in the first three months of 2018.  The increase was primarily due to the increase in capital expenditures, primarily in the Company's Harsco Metals & Minerals Segment in the first three months of 2019, compared with the first three months of 2018.

Net cash provided by financing activities — Net cash provided by financing activities in the first three months of 2019 was $44.4 million, an increase of $5.2 million from net cash provided by financing activities in the first three months of 2018.  The change was primarily due to net cash borrowings of $51.7 million in the first three months of 2019 compared with net cash borrowings of $39.4 million in the three months of 2018; partially offset by the payment of employee taxes related to stock-based compensation vesting.

Sources and Uses of Cash

The Company’s principal sources of liquidity are cash provided by operations and borrowings under the Senior Secured Credit Facility, augmented by cash proceeds from asset sales. In addition, the Company has other bank credit facilities available throughout the world.  The Company expects to continue to utilize all of these sources to meet future cash requirements for operations and growth initiatives.

Summary of Senior Secured Credit Facility Borrowings: (In millions)	March 31 2019		December 31 2018
By type:
Revolving Credit Facility	$	119.0	$	62.0
Term Loan Facility	540.4		541.8

Multi-year revolving credit facility	$	500.0	$	119.0	$	30.4	$	350.6

34

Debt Covenants

The Senior Secured Credit Facility contains a consolidated net debt to consolidated adjusted earnings before interest, tax depreciation and amortization ("EBITDA") ratio covenant, which is not to exceed 3.50 to 1.0, and a minimum consolidated adjusted EBITDA to consolidated interest charges ratio covenant, which is not to be less than 3.0 to 1.0.  At

March 31, 2019, the Company was in compliance with these covenants, as the total net leverage ratio was 1.8 to 1.0 and total interest coverage ratio was 8.6 to 1.0. Based on balances and covenants in effect at March 31, 2019, the Company could increase net debt by $558.8 million, and still be in compliance with these debt covenants. Alternatively, keeping all other factors constant, the Company's adjusted EBITDA could decrease by $159.7 million and the Company would still be within these debt covenants. The Company expects to continue to be in compliance with these debt covenants for at least the next twelve months.

Cash Management

The Company has various cash management systems throughout the world that centralize cash in various bank accounts where it is economically justifiable and legally permissible to do so. These centralized cash balances are then redeployed to other operations to reduce short-term borrowings and to finance working capital needs or capital expenditures. Due to the transitory nature of cash balances, they are normally invested in bank deposits that can be withdrawn at will or in very liquid short-term bank time deposits and government obligations. The Company's policy is to use the largest banks in the various countries in which the Company operates. The Company monitors the creditworthiness of banks and when appropriate will adjust banking operations to reduce or eliminate exposure to less creditworthy banks. The Company plans to continue the strategy of targeted, prudent investing for strategic purposes for the foreseeable future, and to make more efficient use of existing investments.

At March 31, 2019, the Company's consolidated cash and cash equivalents included $84.1 million held by non-U.S. subsidiaries. At March 31, 2019, approximately 1% of the Company's consolidated cash and cash equivalents had regulatory restrictions that would preclude the transfer of funds with and among subsidiaries. Non-U.S. subsidiaries also held $25.6 million of cash and cash equivalents in consolidated strategic ventures. The strategic venture agreements may require strategic venture partner approval to transfer funds with and among subsidiaries. While the Company's remaining non-U.S. cash and cash equivalents can be transferred with and among subsidiaries, the majority of these non-U.S. cash balances will be used to support the ongoing working capital needs and continued growth of the Company's non-U.S. operations.
