HARSCO CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
1. Basis of Presentation
The Company has prepared these unaudited condensed consolidated financial statements in accordance with 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 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, 2019 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2019 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, 2019. 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.
Restricted Cash
The Company had restricted cash of $2.3 million and $2.5 million at June 30, 2020 and December 31, 2019, respectively, and the restrictions are primarily related to collateral provided for certain guarantees of the Company's performance.
Acquisition of ESOL
On April 6, 2020 the Company completed the previously announced acquisition of ESOL, an established waste transportation, processing and services provider with a comprehensive portfolio of disposal solutions for customers primarily across the industrial, retail and healthcare markets from Stericycle, Inc. for $438.8 million in cash, subject to post-closing adjustments. See Note 3, Acquisitions and Dispositions, for additional information.
Segment Reporting
The Company reports information about operating segments using the "management approach," which is based on the way management organizes and reports the segments within the enterprise for making operating decisions and assessing performance. The Company's reportable segments are identified based upon differences in products, service and markets served. The Company has determined that the operations of ESOL will be combined and included as part of the Harsco Clean Earth Segment.
Impact of COVID-19
Beginning in early 2020 overall global economic conditions were significantly impacted by COVID-19. The continuing impact of COVID-19 on the Company varies by end market as well as local conditions (including applicable government mandates) and is continually evolving. The ultimate duration and impact of COVID-19 on the Company and its customers' operations is presently unclear, though the Company continues to operate as a provider of certain essential services in the U.S. and most other countries. The Company continues to take significant and proactive actions to protect all stakeholders and to minimize the operational and financial impacts of COVID-19 where possible.
The Company did not record any long-lived asset impairments, indefinite-lived asset impairments, goodwill impairments, significant inventory write-downs or incremental accounts receivable reserves for current expected credit losses during the three months or six months ended June 30, 2020, however such charges are possible in future periods, which could have an adverse effect on the Company's future results of operations, cash flows, or financial condition.
Discontinued Operations
In January 2020 the Company sold IKG and together with the 2019 sales of AXC and PK, this completes the divestiture of the former Harsco Industrial Segment originally announced in May 2019. These disposals represent a strategic shift and accelerated the transformation of the Company's portfolio of businesses into a leading provider of environmental solutions and services. As a result of these disposals (i) the carrying value of the remaining assets and liabilities of the Harsco Industrial Segment have been classified as Assets held-for-sale and Liabilities of assets held-for-sale on the Company's December 31, 2019 Condensed Consolidated Balance Sheets; (ii) the operating results of the Harsco Industrial Segment, costs directly related to the disposals, an allocation of interest expense associated with mandatory debt repayments required as a result of the disposals and the write-off of deferred financing costs resulting from the mandatory repayment have been reflected in the Company's Condensed Consolidated Statements of Operations as discontinued operations for all periods presented; and (iii) all disclosures have been updated to reflect these changes. See Note 3, Acquisitions and Dispositions, for additional information.
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 2020:
On January 1, 2020 the Company adopted changes issued by the FASB which updated the impairment model for credit losses 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. Provisions for receivables will be recorded as Allowance for expected credit losses, replacing the previously utilized Allowance for doubtful accounts. In addition, these changes required certain expanded disclosures. Other than changes in disclosure, these changes did not have a material impact on the Company's condensed consolidated financial statements as the calculation of expected credit losses did not yield results that were materially different from the methodology previously utilized by the Company. See Note 4, Accounts Receivable and Note Receivable for additional information.
On January 1, 2020 the Company adopted changes issued by FASB that removed 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. These changes did not have a material impact on the Company's condensed consolidated financial statements.
On January 1, 2020 the Company adopted changes issued by FASB which modified 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 OCI 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. Other than required expanded disclosures, the adoption of these changes did not have a material impact on the Company's condensed consolidated financial statements.
The following accounting standards have been issued and become effective for the Company at a future date:
In December 2019 the FASB issued changes which are intended to reduce complexity and simplify the accounting for income taxes in accordance with U.S. GAAP by removing certain exceptions related to investments, intraperiod allocations and interim calculations and clarifying existing guidance to improve consistent application. The changes become effective for the Company on January 1, 2021 with early adoption permitted. Management is currently evaluating the impact of these changes on its condensed consolidated financial statements.
In March 2020 the FASB issued changes that provides companies with optional guidance to ease the potential accounting burden associated with transitioning from reference rates that are expected to be discontinued. In response to the concerns about risks of IBORs and, particularly, the risk of cessation of LIBOR, regulators in several jurisdictions around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. The changes provide optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The changes can be adopted no later than December 31, 2022 with early adoption permitted. Management does not believe these changes will have a material impact on its condensed consolidated financial statements.

3. Acquisitions and Dispositions
ESOL
On April 6, 2020 the Company completed the previously announced acquisition of 100% of ESOL, an established waste transportation, processing and services provider with a comprehensive portfolio of disposal solutions for customers primarily across the industrial, retail and healthcare markets from Stericycle, Inc. for $438.8 million of cash consideration at closing, subject to normal working capital adjustments. In addition, as part of the acquisition, the Company entered into a non-compete agreement with Stericycle, Inc. Concurrent to the ESOL acquisition, the Company entered into an agreement with Stericycle Inc. related to certain Stericycle, Inc. customers who receive services from both ESOL and other Stericycle, Inc. businesses under a single contractual arrangement. The revenue pertaining to services rendered to these customers are invoiced centrally through Stericycle, Inc. billing systems and ESOL's portion of the revenue, less a management fee, is then distributed to the Company.
The preliminary fair value recorded for the assets acquired and liabilities assumed for ESOL is as follows:

|  | Preliminary Valuation |  |  |  |
(In millions) |  | April 6 2020 |  | Measurement Period Adjustments |  | June 30 2020
Cash and cash equivalents |  | $ | 0.4 |  |  | $ | — |  |  | $ | 0.4 |

Total identifiable net assets of ESOL |  | $ | 438.8 |  |  | $ | — |  |  | $ | 438.8 |

The goodwill is primarily attributed to expected operational efficiencies and synergies from the expanded geographical scale of hazardous waste processing facilities resulting from combining the ESOL business with the existing Clean Earth business of the Company, as well as the value associated with the assembled workforce of ESOL. The Company expects $36.8 million of goodwill to be deductible for income tax purposes through 2030.
The following table details the preliminary valuation of identifiable intangible assets and amortization periods for ESOL and the non-compete entered into by the Company upon acquisition of ESOL:

|  |  |  | Preliminary Valuation |  |  |  |
(Dollars in millions) |  | Weighted-Average Amortization Period |  | April 6 2020 |  | Measurement Period Adjustments (a) |  | June 30 2020

Total identifiable intangible assets acquired |  |  |  | $ | 163.5 |  |  | $ | 0.0 |  |  | $ | 163.5 |

The Company valued the identifiable intangible assets using methodologies under the income approach including the multi-period excess earnings method, the distributor method, and the with-and-without method. The purchase price allocation for ESOL is not final and the fair value of intangible assets and goodwill may vary significantly from those reflected in the Company's condensed consolidated financial statements at June 30, 2020.

Table of Contents
ESOL contributed revenue of $107.5 million and an operating loss of $1.9 million for both the three and six months ended June 30, 2020. The operations of ESOL have been combined and included as part of the Harsco Clean Earth Segment.
The three and six months ended June 30, 2020 include ESOL direct acquisition and integration costs of $17.2 million and $30.3 million, respectively, which are included in the Selling, general and administrative expenses, within the Corporate function, in the Company's Condensed Consolidated Statements of Operations. In addition to the acquisition and integration costs reflected in the Company's Condensed Consolidated Statements of Operations, the debt issuance costs associated with the issuance of debt to fund the acquisition are reflected, net of amortization subsequent to the acquisition date, as Long-term debt on the Company's Condensed Consolidated Balance Sheets.
Clean Earth
On June 28, 2019 the Company acquired 100% of the outstanding stock of Clean Earth, one of the largest U.S. providers of specialty waste processing and beneficial reuse solutions for hazardous wastes, contaminated materials and dredged volumes, for an enterprise valuation of approximately $625 million on a cash free, debt free basis, subject to normal working capital adjustments. The Company transferred approximately $628 million of cash consideration and agreed to reimburse the sellers for any usage of assumed net operating losses in a post-closing period for up to five years, the present value of which is estimated at approximately $8 million.
The fair value recorded for the assets acquired and liabilities assumed for Clean Earth is as follows:

|  | Final |  |  |  |
(In millions) |  | June 28, 2019 |  | Measurement Period Adjustments (a) |  | June 30 2020

Pro forma financial information
The pro forma information below gives effect to the Clean Earth acquisition as if it had been completed on January 1, 2018 and the ESOL acquisition as if it had been competed on January 1, 2019. The pro forma information is not necessarily indicative of the Company’s results of operations had the acquisitions been completed on the above dates, nor is it necessarily indicative of future results. The pro forma information does not reflect any cost savings from operating efficiencies or synergies that could result from the acquisitions and does not reflect the additional revenue opportunities following the acquisitions. The pro forma information below includes the adjustments necessary to reflect additional depreciation and amortization expense based on the estimated fair value and useful lives of intangible assets and fixed assets acquired; includes additional interest expense of approximately $4.7 million for the six months ended June 30, 2020 and $14.8 million and $29.4 million for the three and six months ended June 30, 2019, respectively,on the acquisition related borrowings used to finance the acquisitions and excludes certain directly attributable acquisition and integration costs and historic interest expense. These pro forma adjustments are subject to change as additional analysis is performed. The values assigned to the assets acquired and liabilities assumed are based on preliminary valuations, for the ESOL acquisition, and are subject to change as the Company obtains additional information during the remaining measurement period. In addition, the historical ESOL results included $8.9 million for the six months ended June 30, 2020 and $8.9 million and $17.8 million for the three and six months ended June 30, 2019, respectively, of corporate expenses charged to ESOL from Stericycle.

Harsco Industrial Segment
In January 2020 the Company sold IKG for $85 million, including a note receivable with a face value of $40.0 million (initial fair value $34.3 million), and recognized a gain on the sale of $18.4 millionpre-tax (or approximately $9 million after-tax). This disposal along with the disposals of AXC and PK in 2019, represent a strategic shift and accelerates the transformation of the Company's portfolio of businesses into a global, market-leading, single-thesis environmental solutions platform. See Note 4, Accounts Receivable and Note Receivable, for additional information related to the note receivable.
The Harsco Industrial Segment has historically been a separate reportable segment with primary operations in North America and Latin America. In accordance with U.S. GAAP, the results of the former Harsco Industrial Segment are presented as discontinued operations and, as such, have been excluded from both continuing operations and segment results for the three months ended June 30, 2020 and 2019.

4. Accounts Receivable and Note Receivable
Accounts receivable are stated at net realizable value which represents the face value of the receivable less an allowance for expected credit losses. The allowance for expected credit losses is maintained for expected lifetime losses resulting from the inability or unwillingness of customers to make required payments.
The Company’s expected credit loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. When required, the Company adjusts the loss-rate methodology to account for current conditions and reasonable and supportable expectations of future economic and market conditions. The Company generally assesses future economic conditions for a period which corresponds with the contractual life of its accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default.
Prior to the adoption of the new methodology, the Company established an allowance for doubtful accounts based upon a specific-identification method as well as historical collection experience, as appropriate.
Accounts receivable consist of the following:

(In thousands) |  | June 30 2020 |  | December 31 2019
Trade accounts receivable |  | $ | 413,638 |  |  | $ | 323,502 |

Other receivables (c) |  | $ | 19,601 |  |  | $ | 21,265 |

(a) The decrease in the allowance for expected credit losses and doubtful accounts is the final write-off of previously fully-reserved balances in the Harsco Environmental Segment.
(b) Upon the acquisition of ESOL, trade accounts receivable were recorded at $124.1 million, which included approximately $12.1 million of allowance for expected credit losses that was netted against the gross receivable balance as of the acquisition date.
(c) Other receivables include employee receivables, insurance receivable, tax claims and other miscellaneous items not included in Trade accounts receivable, net.
The change in the provision for expected credit losses and doubtful accounts related to trade accounts receivable was as follows:

|  | Three Months Ended |  |  |  | Six Months Ended |  |
|  | June 30 |  |  |  | June 30 |  |

Provision for expected credit losses and doubtful accounts related to trade accounts receivable |  | $ | 18 |  |  | $ | 5,433 |  |  | $ | 237 |  |  | $ | 5,423 |

At June 30, 2020 approximately $4.6 million of the Company's trade accounts receivable were past due by twelve months or more. Approximately $1 million of this amount is reserved, although collection of the remaining balance is still ultimately expected.

Table of Contents
In January 2020 the Company sold IKG for $85 million including cash and a note receivable, subject to post-closing adjustments. The note receivable from the buyer has a face value of $40 million bearing interest at 2.50% that is paid in kind and matures on January 31, 2027. Any unpaid principal, along with any accrued but unpaid interest is payable at maturity. Prepayment is required in case of a change in control or a percentage of excess cash flow, as defined in the note receivable agreement. Because there are no scheduled payments under the terms of the note receivable, the balance is not classified as current as of June 30, 2020 and is included in the caption Other assets on the Condensed Consolidated Balance Sheet. The initial fair value of the note receivable was $34.3 million which was calculated using an average of various discounted cash flow scenarios based on anticipated timing of repayments (Level 3) and was a non-cash transaction. The note receivable is subsequently measured at amortized cost. Key inputs into the valuation model include: projected timing and amount of cash flows, pro forma debt rating, option-adjusted spread and U.S. Treasury spot rate. At June 30, 2020 the amortized cost of the note receivable was $35.0 million, compared with a fair value of $34.7 million.

During 2016 the Company recognized an initial estimated forward loss provision related to the contracts with SBB of $45.1 million. The Company recorded an additional forward loss provision of $1.8 million during 2018. At June 30, 2020 the entire remaining estimated forward loss provision of $7.0 million is included as Other current liabilities on the Company's 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.
The Company recognized $7.6 million and $5.9 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 June 30, 2020 and 2019, respectively, and $17.7 million and $10.6 million for the six months ended June 30, 2020 and 2019, respectively. Consolidated product revenue gross margins were not significantly impacted by the revenue recognized under the SBB contracts for the three and six months ended June 30, 2020 and 2019. The Company has substantially completed the first contract and is approximately 56% complete on the second contract with SBB as of June 30, 2020.

(a) The changes to goodwill primarily relate to the acquisition of ESOL in the Harsco Clean Earth Segment, See note 3, Acquisitions and Dispositions, and an immaterial acquisitions in the Harsco Environmental Segment.
The Company tests for goodwill impairment annually, or more frequently if indicators of impairment exist, or if a decision is made to dispose of a business. The Company performs the annual goodwill impairment test as of October 1 and monitors for triggering events on an ongoing basis. The Company determined that, as of June 30, 2020, no interim goodwill impairment testing was necessary.
The Company has concluded that no triggering event occurred during the three months ended June 30, 2020. However, a prolonged economic downturn resulting from COVID-19 could impact the Company's future projected cash flows used to estimate fair value, and/or result in a sustained decrease in the Company’s share price, which could indicate an impairment.

9. Debt and Credit Agreements
In March 2020 the Company raised $280 million pursuant to the New Term Loan as a new tranche under the existing Senior Secured Credit Facilities. There were no borrowings outstanding under the New Term Loan at March 31, 2020. The New Term Loan was fully drawn on April 6, 2020 to partially fund the acquisition of ESOL. See Note 3, Acquisition and Dispositions for additional information related to the ESOL acquisition. Borrowings under the New Term Loan bear interest at a rate per annum ranging from 150 to 225 basis points over adjusted LIBOR (as defined in the Credit Agreement). The New Term Loan will mature on June 28, 2024. The Company capitalized $1.9 million of fees related to the issuance of the New Term Loan, all of which have been principally paid as of June 30, 2020.
In both March 2020 and June 2020, the Company amended the Senior Secured Credit Facilities to increase the net debt to consolidated adjusted EBITDA ratio covenant. As a result of these amendments, the net debt to consolidated adjusted EBITDA ratio covenant has been increased to 5.25 for June 30, 2020, 5.75 through March 2021 and then decreasing quarterly until reaching 4.75 in December 2021. There is no change to the previously agreed interest rates as long as the Company's total leverage ratio does not equal or exceed 4.50 at which time it would increase by 25 basis points. During the three and six months ended June 30, 2020, the Company recognized $1.4 million and $1.9 million respectively, of fees and expenses related to the amended Senior Secured Credit Facilities in the caption Unused debt commitment and amendment fees on the Condensed Consolidated Statement of Operations.

The Company's estimate of expected contributions to be paid during the remainder of 2020 for the U.S. and international defined benefit pension plans are $5.7 million and $8.4 million, respectively. The recently enacted CARES Act allows for the deferral, until 2021, of certain expected pension contributions in the U.S. The Company is currently evaluating this alternative.
11. Income Taxes
Income tax benefit related to continuing operations for the three and six months ended June 30, 2020 was $2.3 million and $3.0 million, respectively. Income tax expense related to continuing operations for the three and six months ended June 30, 2019 was $4.0 million and $5.2 million, respectively. The change in the income tax benefit for the three and six months ended June 30, 2020 compared with the income tax expense for the three months and six months ended June 30, 2019 is the result of lower taxable income, primarily resulting from decreased operating income as a result of the impacts of COVID-19 and incremental acquisition and integration costs of approximately $5 million and $16 million for the three and six months ended June 30, 2020, respectively, to support the ESOL acquisition.
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 June 30, 2020 was $3.7 million, including interest and penalties. Within the next twelve months, it is reasonably possible that $0.3 million unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
12. 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.
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.

The following table summarizes information related to the location and undiscounted amount of the Company's environmental liabilities:

Total environmental liabilities |  | $ | 36,142 |  |  | $ | 9,031 |

(a) The current portion of environmental liabilities is included in the caption Other current liabilities on the Company's Condensed Consolidated Balance Sheets.
Environmental liabilities relate primarily to the ESOL business which was acquired on April 6, 2020. As part of the ESOL acquisition, the Company assumed control of certain, closed sites that were being monitored as part of ongoing environmental remediation plans. See Note 3, Acquisitions and Dispositions, for additional details.
On June 25 and 26, 2018, the DTSC conducted a compliance enforcement inspection of ESOL’s facility in Rancho Cordova, California, which was then owned by Stericycle, Inc. On February 14, 2020, the DTSC filed an action in the Superior Court for the State of California, Sacramento Division, alleging violations of California’s Hazardous Waste Control Law and the facility’s hazardous waste permit arising from the inspection. That action is ongoing. Separately, Stericycle, Inc. received from DTSC a written Intent to Deny Hazardous Waste Facility Permit Application dated August 5, 2019 for the Rancho Cordova facility. The DTSC has yet to issue a final permit decision. If the DTSC were to deny the permit renewal, the Company would have the right to file an administrative appeal. The Company has not accrued any amounts in respect of these alleged violations and cannot estimate the reasonably possible loss or the range of reasonably possible losses that it may incur. The Company is unable to make such an estimate because litigation is by its nature uncertain and unpredictable. Pursuant to the terms of the Company’s acquisition of ESOL, the Company is indemnified for certain costs and expenses associated with this matter by Stericycle, Inc.
As previously disclosed, the Company has had ongoing meetings with the SCE over processing salt cakes, a processing byproduct, 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 is constructing facilities to process the salt cakes, and the Company currently expects those facilities to come online in 2020. 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 reais per day (or approximately $900 per day) and CSN 20,000 Brazilian reais per day (or approximately $4,000 per day) until the requirements of the injunction are met. On November 1, 2019 the Court issued an additional order increasing the fines assessed to the Company to 25,000 Brazilian reais per day (or approximately $5,000 per day) and raising the fines assessed to CSN to
100,000 Brazilian reais per day (or approximately $19,000 per day). The Court also assessed an additional fine of
10,000,000 Brazilian reais (or approximately $1,900,000) against CSN and the Company jointly. The Company is appealing the fines 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 three additional enforcement actions since that time and have asserted fines of approximately $0.5 million which the Company has recorded, 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.
On June 13, 2019 the PA DEP indicated to the Company and a landowner who received processed slag from the Company that it plans to require action to bring the landowner’s site into compliance and to assess a civil penalty against the Company and the landowner. The Company is working with the landowner and PA DEP to determine the most effective way to address PA DEP’s concerns about the site and has established a $0.4 million reserve, which represents the Company’s best estimate of the costs to bring the landowner's site into compliance.
On March 24, 2017 the Allegheny County Health Department issued a notice of violation against the Company concerning the Company’s operations at a customer site in Natrona, Pennsylvania. On January 21, 2020 the Company paid $0.1 million to settle the civil penalties accrued up to that date. In April 2020, the Company received a penalty assessment of $4,500 for three alleged additional events. It is possible the Company could incur additional penalties for future violations. Pursuant to the settlement agreement, the Company and its customer have also agreed to construct and bring certain slag processing operations into a building.
DEA Investigation
Prior to the Company’s acquisition of ESOL, Stericycle, Inc, notified the Company that the DEA had served an administrative subpoena on Stericycle, Inc. and executed a search warrant at a facility in Rancho Cordova, California and an administrative inspection warrant at a facility in Indianapolis, Indiana. The Company has determined that the DEA and the DTSC have launched investigations involving, at least in part, the ESOL business of collecting, transporting, and destroying controlled substances from retail customers that transferred from Stericycle, Inc. to the Company. In connection with these investigations, the DEA also executed a search warrant on an ESOL facility in Austin Texas on July 2, 2020. The Company is cooperating with these inquiries, which relate primarily to the period before the Company owned the ESOL business. Since the acquisition of the ESOL business, the Company has performed a vigorous review of ESOL’s compliance program related to controlled substances and has made material changes to the manner in which controlled substances are transported from retail customers to DEA-registered facilities for destruction. The Company has not accrued any amounts in respect of these investigations and cannot estimate the reasonably possible loss or the range of reasonably possible losses that it may incur, if any. Investigations of this type are by their nature uncertain and unpredictable. While it is the Company’s position that it has recourse for some or all liabilities, if any, that arise from these matters under the ESOL purchase agreement, there can be no assurances that the Company’s position will ultimately prevail.
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 ICMS, services and social security tax disputes. The largest proportion of the assessed amounts relate to ICMS claims filed by 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 June 30, 2020 the principal amount of the tax assessment from the SPRA with regard to this case is approximately $1.1 million, with penalty, interest and fees assessed to date increasing such amount by an additional $15.7 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 $1 million. After calculating the interest accrued on the penalty, the Company estimates that this ruling reduces the current overall potential liability for this case to approximately $7 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.

Table of Contents
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 has appealed to the judicial phase. The aggregate amount assessed by the tax authorities in August 2005 was $4.7 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 $1.1 million, with penalty and interest assessed through that date increasing such amount by an additional $3.6 million. On December 6, 2018 the administrative tribunal reduced the applicable penalties to $1.1 million. After calculating the interest accrued on the current penalty, the Company estimates that the current overall liability for this case to be approximately $9.3 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.
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 Environmental 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 June 30, 2020 and December 31, 2019 the Company has established reserves of $4.6 million and $6.5 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.

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 June 30, 2020 there were approximately 17,140 pending asbestos personal injury actions filed against the Company. Of those actions, approximately 16,585 were filed in the New York Supreme Court (New York County), approximately 117 were filed in other New York State Supreme Court Counties and approximately 438 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 June 30, 2020 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 35 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.
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 June 30, 2020 the Company has obtained dismissal in approximately 28,253 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, 2019 for additional information on Accrued insurance and loss reserves.

14. 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 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 Company's 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.
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.
The fair value of outstanding derivative contracts recorded as assets and liabilities on the Company's Condensed Consolidated Balance Sheets was as follows:

All of the Company's derivatives are recorded on the Company's 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 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, if offset, would result in a $2.5 million net liability at June 30, 2020 and would not have resulted in a net asset or liability at
December 31, 2019.

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 AOCI, 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.
At June 30, 2020 and December 31, 2019 the notional amounts of foreign currency exchange forward contracts were $453.0 million and $496.3 million, respectively. These contracts are primarily denominated in British pounds sterling and Euros and mature through October 2021.
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 losses of $2.4 million and $12.1 million for the three and six months ended June 30, 2020, respectively and pre-tax net losses of $5.5 million and $0.7 million for the three and six months ended June 30, 2019, respectively, in AOCI.
Interest Rate Swaps
The Company uses interest rate swaps in conjunction with certain variable rate 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 AOCI.
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 Original Term Loan from floating-rate to fixed-rate. The fixed rates provided by the swaps replace the adjusted LIBOR rate in the interest calculation, ranging from 2.45% for 2020 to 3.12% for 2022.
During June 2019 the Company effected the early termination of interest rate swaps that covered the period from 2019 through 2022 and had the effect of converting $100.0 million of the Original Term Loan from floating-rate to fixed-rate. This termination was conducted as a result of the Company's new Notes offering and required repayment of a portion of the Original Term Loan with proceeds from the AXC disposal. The total notional of the Company's interest rate swaps is $200.0 million as of June 30, 2020.
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 AOCI. Changes in value attributed to the effect of foreign currency fluctuations are recorded on the Company's Condensed Consolidated Statements of Operations and offset currency fluctuation effects on the debt principal. The Company had no outstanding CCIRs at June 30, 2020.

Table of Contents
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 June 30, 2020 and December 31, 2019 the total fair value of long-term debt (excluding deferred financing costs), including current maturities, was $1,251.4 million and $827.2 million, respectively, compared with a carrying value of $1,262.4 million and $795.0 million, respectively. The increase in both the fair value and carrying value of long-term debt is related to borrowings under the New Term Loan and the Revolving Credit Facility to fund the acquisition of ESOL. See Note 3, Acquisitions and Dispositions for additional details. 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. See Note 4, Accounts Receivable and Note Receivable for fair value information related to the Company's Note Receivable obtained as part of the sale of the IKG business.

(a) The Company's acquisition of ESOL closed on April 6, 2020 and the Company's acquisition of Clean Earth closed on June 28, 2019. The results of both are included in the Harsco Clean Earth Segment. The operating results of the former Harsco Industrial Segment have been reflected as discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented. See Note 3, Acquisitions and Dispositions, for additional details.
(b) Revenues are attributed to individual countries based on the location of the facility generating the revenue.
(c) Includes Mexico.
The Company may receive payments in advance of earning revenue, which are treated as Advances on contracts on the Company's 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 Company's 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.
The Company had Contract assets totaling $59.0 million and $31.2 million at June 30, 2020 and December 31, 2019, respectively. The increase is due principally to recognition of additional contract assets in excess of contract assets transferred to accounts receivable during the six months ended June 30, 2020 primarily in the Harsco Rail Segment. The Company had Advances on contracts totaling $98.5 million and $60.3 million at June 30, 2020 and December 31, 2019, respectively. The increase is due principally to the receipt of new advances on contracts in excess of recognition of revenue primarily for the Deutsche Bahn contract in the Harsco Rail Segment. During the three and six months ended June 30, 2020 the Company recognized approximately $16 million and $34 million, respectively, of revenue related to amounts previously included in Advances on contracts. During the three and six months ended June 30, 2019 the Company recognized approximately $19 million and $37 million, respectively, of revenue related to amounts previously included in Advances on contracts.
At June 30, 2020 the Harsco Environmental Segment had remaining, fixed, unsatisfied performance obligations where the expected contract duration exceeds one year totaling $98.7 million. Of this amount, $33.0 million is expected to be fulfilled by June 30, 2021, $19.6 million by June 30, 2022, $16.3 million by June 30, 2023, $12.8 million by June 30, 2024 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, 2019 is primarily due to the renegotiation of a contract with a customer in the U.K. who had entered into administration.

Executive Overview
The Company is a market-leading, global provider of environmental solutions for industrial, retail and medical waste streams, and innovative equipment and technology for the rail sector. The Company's operations consist of three reportable segments: Harsco Environmental, Harsco Clean Earth and Harsco Rail; and the Company is working towards transforming Harsco into a single-thesis environmental solutions company that is a global leader in the markets we serve. The Harsco Environmental Segment operates primarily under long-term contracts, providing critical environmental services and material processing to the global steel and metals industries including zero waste solutions for manufacturing byproducts within the metals industry. The Harsco Clean Earth Segment provides waste management services including transportation, specialty waste processing, recycling and beneficial reuse solutions for hazardous wastes, contaminated materials and dredged volumes. 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.
In April 2020 the Company completed the previously announced acquisition of ESOL, from Stericycle, Inc., for $438.8 million in cash, subject to post-closing adjustments. ESOL is an established waste transportation, processing and services provider with a comprehensive portfolio of disposal solutions for customers primarily across the industrial, retail and healthcare markets. ESOL's network includes thirteen permitted TSDF facilities and forty-eight 10-day transfer facilities serving more than ninety-thousand customer locations utilizing a fleet of more than seven-hundred vehicles. The acquisition of ESOL furthers Harsco’s transformation into a global, market-leading, single-thesis environmental solutions platform. The results of ESOL are reflected as part of the Harsco Clean Earth Segment.
In March 2020 the Company raised $280 million pursuant to the New Term Loan as a new tranche under its existing Senior Secured Credit Facilities. The New Term Loan was fully drawn on April 6, 2020 to partially fund the ESOL acquisition. Borrowings under the New Term Loan bear interest at a rate per annum ranging from 150 to 225 basis points over adjusted LIBOR (as defined in the Credit Agreement). The New Term Loan will mature on June 28, 2024. The Company capitalized $1.9 million of fees related to the issuance of the New Term Loan, principally all of which have been paid as of June 30, 2020.
In both March 2020 and June 2020, the Company amended the Senior Secured Credit Facilities to increase the net debt to consolidated adjusted EBITDA ratio covenant. As a result of these amendments, the net debt to consolidated adjusted EBITDA ratio covenant has been increased to 5.25 for June 30, 2020, 5.75 through March 2021 and then decreasing quarterly until reaching 4.75 in December 2021. There is no change to the previously agreed interest rates as long as the Company's total leverage ratio does not equal or exceed 4.50 at which time it would increase by 25 basis points. During the three and six months ended June 30, 2020, the Company recognized $1.4 million and $1.9 million, respectively, of fees and expenses related to the amended Senior Secured Credit Facilities in the caption Unused debt commitment and amendment fees on the Condensed Consolidated Statement of Operations.
In January 2020 the Company sold IKG for $85 million, including a note receivable with a face value of $40.0 million (initial fair value $34.3 million) and recognized a gain on sale of $18.4 million pre-tax (or approximately $9 million after-tax). This disposal, along with the disposals of AXC and PK in 2019, represent a strategic shift and accelerate the transformation of the Company's portfolio of businesses into a global, market-leading, single-thesis environmental solutions platform.
Beginning in March 2020 overall global economic conditions were significantly impacted by COVID-19. The continuing impact of COVID-19 on the Company varies by end market as well as local conditions (including applicable government mandates). The ultimate duration and impact of COVID-19 on the Company and its customers' operations is presently unclear, though the Company expects impacts to continue for at least the remainder for 2020. The Company continues to operate as a provider of certain essential services in the U.S. and most other countries. In addition, the Company continues to take significant and proactive actions to protect all stakeholders and to minimize the operational and financial impacts of COVID-19 where possible. Work safety and flexibility measures have been implemented as the Company strives to keep facilities operational. In addition, the Company is also focused on actions to adjust its cost structure, reduce capital and operating expenditures, and to preserve its financial flexibility and liquidity position. Please refer to the below discussion of business outlook and Part II, Item 1A, "Risk Factors" for additional information related to the potential impacts of COVID-19 on the Company.

Highlights from the second quarter and six months ended June 30, 2020 include (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 second quarter and six months ended June 30, 2020 increased approximately 27% and 24%, respectively, compared with the second quarter and six months ended June 30, 2019. The primary drivers for these increases were the acquisitions of Clean Earth and ESOL as well as increased revenue related to maintenance-of-way equipment sales in the Harsco Rail Segment, partially offset by lower customer production in the Harsco Environmental Segment, inclusive of the impacts from COVID-19, and the impact of foreign currency translation.
•Operating income from continuing operations for the second quarter and six months ended June 30, 2020 decreased approximately 90% and 87%, respectively, compared with the second quarter and six months ended June 30, 2019. The primary drivers for these decreases were decreased customer production levels in the Harsco Environmental Segment, inclusive of the impacts of COVID-19, incremental acquisition and integration costs primarily related to the ESOL acquisition, the timing and mix of sales in the Harsco Rail Segment and severance costs, primarily incurred during the first quarter of 2020, of approximately $6 million in the Harsco Environmental Segment. These decreases were partially offset by the inclusion of operating results for both Clean Earth and ESOL as well as lower selling, general and administrative expenses in Harsco Environmental and Harsco Rail Segments as well as Corporate (exclusive of the aforementioned incremental acquisition and integration costs).
•Diluted loss per common share from continuing operations attributable to Harsco Corporation for the second quarter ended June 30, 2020 was $0.14, an increase compared with the Diluted loss per common share from continuing operations of $0.04 during second quarter ended June 30, 2019. Diluted loss per common share from continuing operations attributable to Harsco Corporation for the six months ended June 30, 2020 was $0.25 compared with the Diluted earnings per common share from continuing operations of $0.09 during six months ended June 30, 2019. In addition to the factors noted above for revenue and operating income from continuing operations, the primary driver of this decrease was increased interest expense partially offset by a decrease in debt-related transaction expenses and the effect of income taxes.
•Cash flows from operating activities for the six months ended June 30, 2020 were $21.5 million, an increase of $16.1 million compared with the Cash flows from operating activities for the six months ended June 30, 2019. The primary driver for this increase were changes in net working capital, primarily additional customer advances in the Harsco Rail Segment and favorable timing of accounts receivable collections, partially offset by lower net income (excluding the impacts of the IKG sale), including the incremental acquisition and integration costs principally related to the ESOL acquisition. This increase also reflects the Company's deferral of certain payroll tax payments and pension contributions, as allowed by various legislation.
•Capital expenditures for purchases of property, plant and equipment for the six months ended June 30, 2020 were $51.2 million, a decrease of $40.0 million or 43.8% compared with the first six months of 2010. The decrease was the result of the Company's goal of maintaining financial flexibility and cash flow during COVID-19.
Looking forward, the Company expects a positive long-term outlook across all businesses, however results will be negatively impacted by COVID-19 for at least the remainder of 2020. The Company’s view for the remainder of 2020 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, 2019 together with those described in Part II, Item 1A, "Risk Factors":
•As a result of the continuing and evolving impact of COVID-19 on the global economy, the Company anticipates slow-downs in customer demand and business disruption to continue for the foreseeable future. The ultimate extent and duration of such impacts on the Company's businesses is not presently known, though the Company expects impacts to continue for at least the remainder of 2020. The Company is continuing to work diligently and safely to provide customers with services and products.
•The Harsco Environmental Segment continues to operate in most countries throughout the world in which it has a presence to support critical metal production, although the Company has been impacted by an overall decline in global steel production. Several customer mill locations where production was temporary idled during March and April 2020, as a result of COVID-19, have restarted though overall production remains below normalized levels and will remain so until underlying demand recovers. Estimated customer mill utilization decreased by 22% and 14% for the second quarter and six months ended June 30, 2020, respectively, compared with the same periods in the prior year. Over the longer-term the Company expects that the Harsco Environmental Segment's return to growth will be driven by investments, innovation and economic growth that supports higher customer steel production.

•The Harsco Clean Earth Segment locations are currently operating as an essential services provider throughout the U.S., enabling the business to continue to perform critical environmental services. However, in the near term it is likely that recent decreases in construction and industrial related activity, resulting from COVID-19, will impact the contaminated materials and hazardous waste lines of business. Contaminated soil volumes are down approximately 10% during the six months ended June 30, 2020 when compared to the same period in prior year. The immediate impact of COVID-19 on the hazardous waste line of business, including the recently completed ESOL acquisition, will vary by end market with certain end-markets such as medical waste and retail, being somewhat more resilient though the Company may experience lower volumes in the near term. In addition, the dredged materials line of business is expected to be less impacted by COVID-19 and has seen an increase in volumes for the first six months of 2020 when compared to the same period in prior year. Over the longer-term the Company expects growth opportunities, including the recently completed ESOL transaction, positive market trends, operational synergy opportunities and the less cyclical and recurring nature of this business to provide favorable returns on the Company's recent investments.
•The Harsco Rail Segment continues to fulfill orders critical to global transportation and is on track to increase capacity during the remainder of 2020 through the implementation of its Supply Chain Operation Recovery program allowing the business to deliver on its backlog. In the near term, the Harsco Rail Segment has begun to be impacted by a decrease in certain short-cycle and equipment sales as a result of COVID-19, primarily in the U.S., which is likely to continue in the second half of 2020. Overall, the Harsco Rail Segment is supported by record backlog, which grew during the second quarter of 2020, and the longer-term outlook for this business remains strong.
•The Company has announced plans to lower 2020 capital expenditures by approximately $75 million from an originally expected range of $170 million to $180 million, exclusive of the ESOL acquisition, with the goal of preserving positive free cash flow (cash flows from operations; deduct capital expenditures; add back proceeds from asset sales; add back transaction-related expenditures) for the year.
•The Company anticipates corporate cost reductions during 2020 to partially offset the impact of COVID-19. Additionally, the Company has developed a tiered approach to potential supplemental cost mitigation efforts should the impacts of COVID-19 on the Company's businesses become more severe or prolonged in nature.
•Interest expense for 2020 is expected to increase due to higher average debt balances during 2020 and the impact of a higher weighted-average interest rate resulting from the issuance of the 5.75% Notes in 2019 and the New Term Loan.
•Net periodic pension cost will decrease by approximately $12 million during 2020 which will primarily be reflected in the caption Defined benefit pension (income) expense on the Condensed Consolidated Statement of Operations. The decrease is primarily the result of higher plan asset values at December 31, 2019.

Comparative Analysis of Consolidated Results
Revenues
Revenues for the second quarter of 2020 increased $96.4 million or 27.5% from the second quarter of 2019. Revenues for the first six months of 2020 increased $165.3 or 24.3% from the second quarter of 2019. Foreign currency translation decreased revenues by approximately $13 million and $25 million for the second quarter and six months ended June 30, 2020, respectively, compared with the same periods 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 second quarter of 2020 increased $97.9 million or 36.8% from the second quarter of 2019. Cost of services and products sold for the first six months of 2020 increased $163.2 or 31.6% from the second quarter of 2019. The changes in cost of services and products sold were attributable to the following significant items:

|  | June 30, 2020 |  |
(In millions) |  | Three Months Ended |  | Six Months Ended
Impact of ESOL and Clean Earth acquisitions |  | $ | 136.0 |  |  | $ | 199.4 |
Change in costs due to changes in revenues (exclusive of the ESOL and Clean Earth acquisitions and effects of foreign currency translation and including fluctuations in commodity costs included in selling prices) |  | (27.6) |  |  | (14.7) |
Impact of foreign currency translation |  | (10.0) |  |  | (19.3) |
Other |  | (0.5) |  |  | (2.2) |
Total change in cost of services and products sold — 2020 vs. 2019 |  | $ | 97.9 |  |  | $ | 163.2 |

Selling, General and Administrative Expenses
Selling, general and administrative expenses for the second quarter of 2020 increased $13.3 million or 19.7% from the second quarter of 2019. Selling, general and administrative expenses for the first six months of 2020 increased $29.4 million or 23.7% from the first six months of 2019. This increase primarily relates to incremental acquisition and integration costs of approximately $16 million during the six months ended June 30, 2020, primarily related to the acquisition of ESOL and the inclusion of selling, general and administrative expenses associated with the ESOL and Clean Earth acquisitions which occurred in April 2020 and June 2019, respectively. These increases were partially offset by decreased compensation expense resulting from lower incentive accruals including a favorable adjustment in the second quarter of 2020 of $4.5 million of incentives accrued during the first quarter of 2020, a provision for doubtful accounts of $5.4 million related to a U.K. customer that entered administration during the second quarter 2019 that did not repeat and decreased travel and entertainment expenses.

Other expenses, net |  | $ | (292) |  |  | $ | (1,717) |  |  | $ | 5,441 |  |  | $ | 26 |

Interest Expense
Interest expense during the second quarter and first six months of 2020 increased by $8.9 million and $16.0 million, respectively, compared with the second quarter and first six months 2019. This increase primarily relates to higher outstanding borrowings and weighted average interest rates related to the June 2019 issuance of the 5.75% Notes and the April 2020 issuance of the New Term Loan.
Unused Debt Commitment and Amendment Fees
During the three and six months ended June 30, 2020, the Company recognized $1.4 million and $1.9 million, respectively, of fees and expenses related to the amended Senior Secured Credit Facilities in the caption Unused debt commitment and amendment fees on the Condensed Consolidated Statement of Operations.
42

Table of Contents
During the second quarter of 2019, the Company recognized $6.7 million of expenses for fees and other costs related to the unused bridge financing commitment that the Company arranged in the event that the Notes were not issued prior to the acquisition of Clean Earth. Additionally, the Company recognized $0.7 million of expenses related to the amendment of the Original Term Loan.
Defined Benefit Pension Income (Expense)
Defined benefit pension income for the second quarter of 2020 was $1.7 million, compared with defined benefit pension expense of $1.5 million for the second quarter of 2019. Defined benefit pension income for the first six months of 2020 was $3.3 million, compared with defined benefit pension expense of $2.8 million for the first six months of 2019. These changes are primarily the result of higher plan asset values at December 31, 2019.
Income Tax Expense
Income tax benefit related to continuing operations for the second quarter and first six months of 2020 was $2.3 million and $3.0 million, respectively, compared with income tax expense related to continuing operations for the second quarter and the first six months of 2019 was $4.0 million and $5.2 million, respectively. This change is the result of lower taxable income, primarily resulting from the incremental acquisition and integration costs of approximately $16 million to support the ESOL acquisition, and decreased operating income as a result of the impacts of COVID-19.
Income (Loss) from Continuing Operations
The Loss from continuing operations was $9.6 million and $17.3 million for the second quarter and first six months of 2020, respectively, compared with Loss from continuing operations of $0.6 million and income from continuing operations was $11.7 million for the second quarter and the first six months of 2019, respectively, The primary drivers for these decreases are noted above.
Gain on Sale of Discontinued Business
In January 2020 the Company sold IKG and recognized a gain on sale of $18.4 million pre-tax (or approximately $9 million after-tax).
Income from Discontinued Operations
The operating results of the former Harsco Industrial Segment, costs directly related to these disposals, an allocation of interest expense associated with mandatory debt repayments required as a result of the disposals and the write-off of deferred financing costs resulting from the mandatory repayment have been reflected as discontinued operations in the Company's Condensed Consolidated Statement of Operations for all periods presented. See Note 3, Acquisitions and Dispositions, in Part I, Item 1, Financial Statements.
Total Other Comprehensive Income (Loss)
Total other comprehensive income was $13.0 million and other comprehensive loss was $17.0 million, respectively, in the second quarter and first six months of 2020 compared with Total other comprehensive income of $3.6 million and $8.1 million, respectively, in the second quarter and the first six months of 2019. The primary driver of the decrease for the comparative six month period is due to the strengthening of the U.S. against certain currencies including the impact of foreign currency translation of cumulative unrecognized actuarial losses on the Company’s pension obligations.
Liquidity and Capital Resources
In March 2020 the Company raised the $280 million New Term Loan as a new tranche under the existing Senior Secured Credit Facilities. The New Term Loan was fully drawn on April 6, 2020 to partially fund the acquisition of ESOL. See Note 3, Acquisition and Dispositions for additional information related to the ESOL acquisition. Borrowings under the New Term Loan bear interest at a rate per annum ranging from 150 to 225 basis points over adjusted LIBOR (as defined in the Credit Agreement). The New Term Loan will mature on June 28, 2024.
In both March 2020 and June 2020, the Company amended the Senior Secured Credit Facilities to increase the net debt to consolidated adjusted EBITDA ratio covenant. As a result of these amendments, the net debt to consolidated adjusted EBITDA ratio covenant has been increased to 5.25 for June 30, 2020, 5.75 through March 2021 and then decreasing quarterly until reaching 4.75 in December 2021. There is no change to the previously agreed interest rates as long as the Company's total leverage ratio does not equal or exceed 4.50 at which time it would increase by 25 basis points.

Cash Flow Summary
The global economy continues to be impacted by COVID-19, the ultimate extent and duration of which is not presently known, and the Company expects its liquidity to continue to be negatively impacted in the near term. As a result, the Company has taken significant proactive actions to minimize the operational and financial impacts. In addition, the Company is focused on actions to include adjusting its cost structure, reducing discretionary capital and operating expenditures, improving working capital management in order to preserve its financial flexibility and liquidity position.
The Company currently expects to have sufficient financial liquidity and borrowing capacity to support the strategies within each of its businesses, inclusive of the impacts of COVID-19. The Company currently expects operational and business needs to be met by cash provided by operations, supplemented with borrowings principally under the Senior Secured Credit Facility due to historic patterns of seasonal cash flow, the funding of various projects, and the impact of COVID-19.
The Company’s cash flows from operating, investing and financing activities, as reflected on the Company's Condensed Consolidated Statements of Cash Flows, are summarized in the following table:

|  | Six Months Ended |  |
|  | June 30 |  |
(In millions) |  | 2020 |  | 2019
Net cash provided (used) by: |  |  |  |
Operating activities |  | $ | 21.5 |  |  | $ | 5.4 |
Investing activities |  | (451.9) |  |  | (677.5) |
Financing activities |  | 461.5 |  |  | 714.3 |
Effect of exchange rate changes on cash and cash equivalents, including restricted cash |  | (6.8) |  |  | (0.2) |
Net change in cash and cash equivalents, including restricted cash |  | $ | 24.3 |  |  | $ | 41.9 |

Net cash provided by operating activities — Net cash provided by operating activities in the first six months of 2020 was $21.5 million, an increase of $16.1 million from the first six months of 2019. The primary driver for this increase were changes in net working capital, primarily additional customer advances in the Harsco Rail Segment and favorable timing of accounts receivable collections, partially offset by lower net income (excluding the impacts of the IKG sale), including the incremental acquisition and integration costs principally related to the ESOL acquisition. This increase also reflects the Company's deferral of certain payroll tax payments and pension contributions, as allowed by various legislation.
Net cash used by investing activities — Net cash used by investing activities in the first six months of 2020 was $451.9 million, a decrease of $225.6 million from the first six months of 2019. The decrease was primarily due to a decrease in cash paid for purchases of businesses, lower capital expenditures primarily in the Harsco Environmental Segment and proceeds from the sale of the IKG business.
Net cash provided by financing activities — Net cash provided by financing activities in the first six months of 2020 was $461.5 million, a decrease of $252.8 million from the first six months of 2019. The decrease was primarily due to lower net cash borrowings of $468.9 million in the first six months of 2020 compared with net cash borrowings of $737.1 million in the six months of 2019 due to lower cash paid for businesses and capital expenditures; partially offset by a decreases in the payments of deferred financing costs and decreases in payments of employee taxes related to stock-based compensation vesting.
Effect of exchange rate changes on cash and cash equivalents, including restricted cash — The decrease is due to the impact of the significant strengthening of the U.S. dollar against certain currencies during the first six months of 2020 on the global cash balances held by the Company in these currencies, including balances held in the Company’s multicurrency cash pool. The most significant impacts were the Mexican peso, the Brazilian real, the Canadian dollar and the Australian dollar.
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.

(a) All amounts outstanding under the Senior Secured Credit Facilities and Notes are classified as long-term on the Company's Condensed Consolidated Balance Sheets at both June 30, 2020 and December 31, 2019.

|  | June 30, 2020 |  |  |  |  |  |
(In millions) |  | Facility Limit |  | Outstanding Balance |  | Outstanding Letters of Credit |  | Available Credit
Multi-year revolving credit facility |  | $ | 700.0 |  |  | $ | 252.0 |  |  | $ | 25.4 |  |  | $ | 422.6 |

Debt Covenants
The Senior Secured Credit Facility contains a consolidated net debt to consolidated adjusted EBITDA ratio covenant, which is not to exceed 5.25 for June 30, 2020, 5.75 through March 2021 and then decreasing quarterly until reaching 4.75 in December 2021, and a minimum consolidated adjusted EBITDA to consolidated interest charges ratio covenant, which is not to be less than 3.0. At June 30, 2020 the Company was in compliance with these covenants, as the total net debt to adjusted EBITDA ratio was 3.9 and total interest coverage ratio was 5.7. Based on balances and covenants in effect at June 30, 2020 the Company could increase net debt by $393.0 million and remain in compliance with these debt covenants. Alternatively, adjusted EBITDA could decrease by $74.9 million, and the Company would remain in compliance with these covenants. The Company has estimated the negative impact of COVID-19 on its financial position, results of operations and cash flows, and believes it will continue to maintain compliance with these covenants. However, due to the inherent uncertainty of COVID-19 on the Company’s businesses, the Company’s estimates of compliance with these covenants could change in the future.
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.
At June 30, 2020 the Company's consolidated cash and cash equivalents included $76.6 million held by non-U.S. subsidiaries. At June 30, 2020 less than 2% 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 $24.1 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.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
As of June 30, 2020, an evaluation was performed, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures pursuant to Rule 13a-15 under the Securities and Exchange Act of 1934, as amended. Based upon that evaluation, and subject to the exclusion below related to ESOL, such officers concluded that the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Securities and Exchange Act of 1934, as amended (1) is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and (2) is accumulated and communicated to the Company's management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.
In accordance with interpretive guidance issued by SEC staff, companies are allowed to exclude acquired businesses from the assessment of internal control over financial reporting during the first year after completion of an acquisition and from the assessment of disclosure controls and procedures to the extent subsumed in such internal control over financial reporting (the “Internal Controls Guidance”). In accordance with the Internal Controls Guidance, as the Company acquired ESOL on April 6, 2020, management's evaluation and conclusion as to the effectiveness of the Company's disclosure controls and procedures as of June 30, 2020 excluded the portion of disclosure controls and procedures that are subsumed by internal control over financial reporting of ESOL. ESOL’s assets represented approximately 11% of the Company’s consolidated total assets, excluding the effects of purchase accounting, and its revenues represented approximately 24% of the Company's consolidated total revenues, as of and for the quarter ended June 30, 2020.
Changes in Internal Control Over Financial Reporting
On June 28, 2019, the Company acquired Clean Earth. The Company has completed the process of transitioning Clean Earth to the Company's internal control over financial reporting. The Company will include Clean Earth in the assessment of internal control over financial reporting as of December 31, 2020.
On April 6, 2020 the Company acquired ESOL from Stericycle, Inc. As a result, the Company is currently integrating ESOL's operations into its overall system of internal control over financial reporting. Under the guidelines established by the SEC, companies are permitted to exclude acquisitions from their assessment of internal control over financial reporting during the year of acquisition. Accordingly, the Company expects to exclude ESOL from the assessment of internal control over financial reporting as of December 31, 2020.
Prior to the acquisition of ESOL, Stericycle, Inc. had identified two material weaknesses related to ESOL's internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement in annual or interim financial statements will not be prevented or detected on a timely basis. The first material weakness relates to not fully implementing and monitoring general information technology controls in the areas of user access and program change management for systems supporting Stericycle Inc.'s internal control process, including ESOL. The second material weakness relates to not fully designing, implementing and monitoring controls relevant to revenue and cost of disposal processes, including certain general information technology controls. While we have undertaken additional compensating processes and controls, we are not yet in a position to conclude that the material weaknesses have been remediated as of June 30, 2020. As a result, there is a risk that a material error may not be detected by our internal control structure that could result in a material misstatement to ESOL's reported financial results, which are consolidated with the Company's results. The Company's management is in the process of remediating these material weaknesses.
Other than the foregoing, there were no changes in the Company's internal control over financial reporting during the Company's most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

ITEM 1. LEGAL PROCEEDINGS
Information on legal proceedings is included in Note 12, Commitments and Contingencies, in Part I, Item 1, Financial Statements.
ITEM 1A. RISK FACTORS
The Company's risk factors as of June 30, 2020 have not changed materially from those described in Part 1, Item 1A, "Risk Factors" of the Company's Annual Report on Form 10-K for the year ended December 31, 2019, except for the risk factor below.
Outbreaks of disease and health epidemics, such as COVID-19, could have a negative impact on the Company's business revenues, financial position, results of operations and/or stock price.
In late December 2019 a notice of pneumonia of unknown cause originating from Wuhan, Hubei province of China was reported to the World Health Organization. A novel coronavirus called coronavirus disease 2019 was identified, with cases soon confirmed in multiple provinces in China, as well as in several other countries. On March 2, 2020, the World Health Organization declared the coronavirus outbreak a “pandemic”, which is disease that is widespread around the world with an impact on society. Since that time the virus has been identified in virtually every country, travel to and from most countries has been suspended or restricted by air carriers and foreign governments, and extended shutdowns of certain businesses and other activities in many countries have occurred and/or remain ongoing. This has led to disruptions in global supply chains, as well as steep downturns and price volatility in equity markets.
COVID-19 continues to impact worldwide economic activity and pose the risk that the Company or its employees, contractors, suppliers, customers and other business partners may be prevented from conducting certain business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities or otherwise elected by the Company or its customers as a preventive measure to limit the spread of coronavirus disease 2019. In addition, mandated government authority measures or other measures elected by companies as preventative measures may lead to the Company's customers being unable to complete purchases or other activities.
COVID-19 may have an adverse effect on the Company's operations and, given the uncertainty around the extent and timing of the potential future spread or mitigation and around the imposition or relaxation of protective measures, the Company cannot reasonably estimate the impact to the Company's future results of operations, cash flows, financial condition or stock price.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
On May 2, 2018 the Company announced that the Board of Directors adopted a share repurchase program, authorizing the Company to repurchase up to $75,000,000 of outstanding shares of the Company’s common stock through April 24, 2021. The Company did not purchase any shares of common stock under this program during the quarter ended June 30, 2020. The approximate dollar value of shares that may yet be purchased under the share repurchase program is $13,151,485. When and if appropriate, repurchases are made in open market transactions, depending on market conditions. Share repurchases may not occur and may be discontinued at any time.
