NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1. Basis of Presentation and Summary of Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared by management of Minerals Technologies Inc. (the “Company”, “MTI”, “we”, or “us”) in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month and six-month periods ended June 28, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020.
Company Operations
The Company is a resource- and technology-based company that develops, produces and markets worldwide a broad range of specialty mineral, mineral-based and synthetic mineral products and supporting systems and services.
The Company has four reportable segments: Performance Materials, Specialty Minerals, Refractories and Energy Services.

– | The Performance Materials segment is a leading global supplier of bentonite and bentonite-related products and leonardite. This segment also provides products for non-residential construction, environmental and infrastructure projects worldwide, serving customers engaged in a broad range of construction projects.

– | The Specialty Minerals segment produces and sells the synthetic mineral product precipitated calcium carbonate (“PCC”) and processed mineral product quicklime (“lime”), and mines mineral ores then processes and sells natural mineral products, primarily limestone and talc.

– | The Refractories segment produces and markets monolithic and shaped refractory materials and specialty products, services and application and measurement equipment, and calcium metal and metallurgical wire products.

– | The Energy Services segment provides services to improve the production, costs, compliance, and environmental impact of activities performed in the oil and gas industry. This segment offers a range of patented and unpatented technologies, products and services to the upstream and downstream oil and gas sector throughout the world.

Use of Estimates
The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to revenue recognition, valuation of long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances, and pension plan assumptions. Actual results could differ from those estimates.
Recently Adopted Accounting Standards
Measurement of Credit Losses on Financial Instruments
In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments", which replaces existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost. The Company adopted this guidance on January 1, 2020 using a modified retrospective transition method. The Company did not record a cumulative-effect adjustment upon adoption of this standard. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.

Recently Issued Accounting Standards
Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of operations.
Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging
In January 2020, the FASB issued ASU 2020-01, "Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging", which addresses the accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The standard is effective for interim and annual periods beginning on or after December 15, 2020. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Note 2. COVID-19
In March 2020, the World Health Organization categorized the novel coronavirus (COVID-19) as a pandemic. Around the world, the Company has been closely adhering to all government regulations as they are issued. Applicable governmental directives across the United States and other global locations have typically permitted the continued operation of essential critical infrastructure sectors. As the Company supplies products and services to many essential industries, including critical manufacturing and energy sectors, all of our operations have qualified as essential businesses. Accordingly, all of the Company’s production facilities are currently operational. In a few locations, however, sites were temporarily impacted by the pandemic.
The recent economic environment related to the rapidly evolving global pandemic, which has slowed business activity in several key end-markets, negatively impacted the Company’s second quarter results and will continue to impact our results in the third quarter. The extent to which our operations will continue to be impacted by the pandemic will depend largely on future developments, including the continued severity of the pandemic and future actions by government authorities to contain it or treat its impact. These conditions are highly uncertain and cannot be accurately predicted. The Company will continue to actively monitor and respond to the COVID-19 pandemic.
As we cannot predict the duration or scope of the COVID-19 pandemic and its impact on our customers and suppliers, the negative financial impact to our future results cannot be reasonably estimated, but could be material. We are actively managing the business to maintain cash flow and we have significant liquidity. We believe that these factors will allow us to meet our anticipated funding requirements.
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment with 50% due by December 31, 2021 and the remaining 50% due by December 31, 2022. The CARES Act is not expected to have a material impact on the Company’s consolidated financial statements.

Options to purchase 1,448,699 shares and 470,304 shares of common stock for the three-month and six-month periods ended June 28, 2020 and June 30, 2019, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares.
Note 5. Restructuring and Other Items, net
During the second quarter of 2019, the Company initiated a restructuring and cost savings program to better align our costs and organizational structure with the current market environment. The Company recorded a $7.5 million non-cash impairment of assets charge related to facilities no longer operating and underutilization of certain equipment, and $5.7 million in other restructuring costs in the second quarter of 2019.
In June 2020, Verso Papers announced they would be idling two of their paper mills indefinitely. As a result, the Company recorded a non-cash write-down of assets charge of $6.0 million and $0.3 million in severance related costs for its Paper PCC satellite facilities at these mills.
The following table outlines the amount of restructuring charges recorded within the Consolidated Statements of Income and the segments they relate to for the three and six-months ending June 28, 2020 and June 30, 2019:

Note 6. Income Taxes
Provision for taxes was $0.9 million and $10.6 million during the three and six-month periods ended June 28, 2020, respectively. The effective tax rate was 6.2%, as compared with 15.8% in the prior year. The lower effective tax rate was primarily due to restructuring and other charges and to the mix of earnings.

(Unaudited)
As of June 28, 2020, the Company had approximately $8.2 million of total unrecognized income tax benefits. Included in this amount were a total of $5.5 million of unrecognized income tax benefits that, if recognized, would affect the Company’s effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company.
The Company’s accounting policy is to recognize interest and penalties accrued relating to unrecognized income tax benefits as part of its provision for income taxes. The Company had a net increase of approximately $0.1 million and $0.2 million during the three and six-months ended June 28, 2020 and an accrued balance of $2.2 million of interest and penalties as of June 28, 2020.
The Company operates in multiple taxing jurisdictions, both within and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to income tax examinations by tax authorities for years prior to 2010.

Note 8. Goodwill and Other Intangible Assets
Goodwill and other intangible assets with indefinite lives are not amortized, but instead are assessed for impairment, at least annually. The carrying amount of goodwill was $805.8 million and $807.4 million as of June 28, 2020 and December 31, 2019, respectively. The change in goodwill from December 31, 2019 to June 28, 2020 is attributable to the effects of foreign exchange.
Intangible assets subject to amortization as of June 28, 2020 and December 31, 2019 were as follows:

|  |  |  |  | June 28, 2020 |  |  | December 31, 2019 |
(millions of dollars) |  | Weighted Average Useful Life (Years) |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |

|  |  | 32 |  |  | $ | 253.9 |  |  | $ | 55.4 |  |  | $ | 253.8 |  |  | $ | 50.8 |

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 32 years. Estimated amortization expense is $4.8 million for the remainder of 2020, $36.4 million for 2021–2024 and $157.3 million thereafter.
Note 9. Derivative Financial Instruments
As a multinational corporation with operations throughout the world, the Company is exposed to certain market risks. The Company uses a variety of practices to manage these market risks, including, when considered appropriate, derivative financial instruments. The Company's objective is to offset gains and losses resulting from interest rates and foreign currency exposures with gains and losses on the derivative contracts used to hedge them. The Company uses derivative financial instruments only for risk management and not for trading or speculative purposes.
12

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
By using derivative financial instruments to hedge exposures to changes in interest rates and foreign currencies, the Company exposes itself to credit risk and market risk. Credit risk is the risk that the counterparty will fail to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty, and therefore, it does not face any credit risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with major financial institutions.
Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates, currency exchange rates, or commodity prices. The market risk associated with interest rate and forward exchange contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.
Cash Flow Hedges
For derivative instruments that are designated and qualify as cash flow hedges, the Company records the effective portion of the gain or loss in accumulated other comprehensive income (loss) as a separate component of shareholders' equity. The Company subsequently reclassifies the effective portion of gain or loss into earnings in the period during which the hedged transaction is recognized in earnings.
The Company utilizes interest rate swaps to limit exposure to market fluctuations on floating-rate debt. In the second quarter of 2018, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. The fair value of this swap is a liability of $9.2 million at June 28, 2020 and is recorded in other non-current liabilities on the Condensed Consolidated Balance Sheet. In addition, in the second quarter of 2016, the Company entered into a floating to fixed interest rate swap with an initial aggregate notional amount of $300 million. The notional amount was $57 million at June 28, 2020. The fair value of this swap is a liability of $0.2 million at June 28, 2020 and is recorded in other current liabilities on the Condensed Consolidated Balance Sheet. These interest rate swaps are designated as cash flow hedges. As a result, the gains and losses associated with these interest rate swaps are recorded in accumulated other comprehensive income (loss).
Net Investment Hedges
For derivative instruments that are designated and qualify as net investment hedges, the Company records the effective portion of the gain or loss in accumulated other comprehensive income (loss) as a separate component of shareholders' equity.
To protect the value of our investments in our foreign operations against adverse changes in foreign currency exchange rates, the Company from time to time hedges a portion of our net investment in one or more of our foreign subsidiaries. During the second quarter of 2018, the Company entered into a cross currency rate swap with a total notional value of $150 million to exchange monthly fixed-rate interest payments in U.S. dollars for monthly fixed-rate interest rate payments in Euros. This contract matures in May 2023 and requires the exchange of Euros and U.S. dollar principal payments upon maturity. The fair value of this swap is an asset of $15.1 million at June 28, 2020 and is recorded in other assets and deferred charges on the Condensed Consolidated Balance Sheet. Changes in the fair value of this financial instrument are recognized in accumulated other comprehensive income (loss) to offset the change in the carrying amount of the net investment being hedged. Amounts are reclassified out of accumulated other comprehensive income (loss) into earnings when the hedged net investment is either sold or substantially liquidated.
Assets and liabilities measured at fair value are based on one or more of three valuation techniques. The three valuation techniques are as follows:

● | Market approach - prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

● | Cost approach - amount that would be required to replace the service capacity of an asset or replacement cost.

● | Income approach - techniques to convert future amounts to a single present amount based on market expectations, including present value techniques, option-pricing and other models.

The Company primarily applies the income approach for interest rate derivatives for recurring fair value measurements and attempts to utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.
The fair value of our interest rate and cross currency rate swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets and are categorized as Level 2.

On May 9, 2014, in connection with the acquisition of AMCOL International Corporation (“AMCOL”), the Company entered into a credit agreement providing for a $1.560 billion senior secured term loan facility (the “Term Facility”) and a $200 million senior secured revolving credit facility.
On June 23, 2015, the Company entered into an amendment (the “First Amendment”) to the credit agreement to reprice the $1.378 billion then outstanding on the Term Facility. As amended, the Term Facility had a $1.078 billion floating rate tranche and a $300 million fixed rate tranche. On February 14, 2017, the Company entered into an amendment (the “Second Amendment”) to the credit agreement to reprice the $788 million floating rate tranche then outstanding, which extended the maturity and lowered the interest costs by 75 basis points. On April 18, 2018, the Company entered into an amendment (the “Third Amendment”) to the credit agreement to refinance its then existing senior secured revolving credit facility. In connection with the Third Amendment, the existing senior secured revolving credit facility was replaced with a new revolving credit facility with $300 million of aggregate commitments (the “Revolving Credit Facility” and, together with the Term Facility, the “Senior Secured Credit Facilities”). Following the amendments, the loans outstanding under the floating rate tranche of the Term Facility are scheduled to mature on February 14, 2024, the loans outstanding under the fixed rate tranche of the Term Facility are scheduled to mature on May 9, 2021 and the loans outstanding (if any) and commitments under the Revolving Facility will mature and terminate, as the case may be, on April 18, 2023. Loans under the floating rate tranche of the Term Facility bear interest at a rate equal to an adjusted LIBOR rate (subject to a floor of 0.75%) plus an applicable margin equal to 2.25% per annum. Loans under the fixed rate tranche of the Term Facility bear interest at a rate of 4.75%. Loans under the Revolving Facility bear interest at a rate equal to an adjusted LIBOR rate plus an applicable margin equal to 1.625% per annum. Such rates are subject to decrease by up to 25 basis points in the event that, and for so long as, the Company’s net leverage ratio (as defined in the credit agreement) is less than certain thresholds. The floating rate tranche of the Term Facility was issued at par and the fixed rate tranche of the Term Facility was issued at a 0.25% discount in connection with the First Amendment. The variable rate tranche of the Term Facility was issued at a 0.25% discount in connection with the Second Amendment. The variable rate tranche has a 1% required amortization per year. The Company will pay certain fees under the credit agreement, including customary annual administration fees. The obligations of the Company under the Senior Secured Credit Facilities are unconditionally guaranteed jointly and severally by, subject to certain exceptions, all material domestic subsidiaries of the Company (the “Guarantors”) and secured, subject to certain exceptions, by a security interest in substantially all of the assets of the Company and the Guarantors.
The credit agreement contains certain customary affirmative and negative covenants that limit or restrict the ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions. In addition, the credit agreement contains a financial covenant that requires the Company, if on the last day of any fiscal quarter loans or letters of credit were outstanding under the Revolving Facility (excluding up to $25 million of letters of credit), to maintain a maximum net leverage ratio (as defined in the credit agreement) of 3.50 to 1.00 for the four fiscal quarters preceding such day. In connection with the Sivomatic acquisition, the Company incurred $113 million of short-term debt under the Revolving Facility. As of June 28, 2020, there were $100 million in outstanding loans and $9.4 million in letters of credit outstanding under the Revolving Facility. The Company is in compliance with all the covenants associated with the Revolving Facility as of the end of the period covered by this report.

As part of the Sivomatic acquisition, the Company assumed $10.7 million in long-term debt, recorded at fair value, consisting of two term loans, one of which matures in 2020 and the other of which matures in 2022. These loans carry an interest rate of Euribor plus 2.0% and have quarterly repayments. During the first half of 2020, the Company repaid $1.0 million on these loans.
The Company has a committed loan facility in Japan. As of June 28, 2020, $4.3 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2021. The Company repaid $0.3 million on this facility during the first half of 2020.
As of June 28, 2020, the Company had $41.8 million in uncommitted short-term bank credit lines, of which approximately $0.3 million was in use.
Note 11. Benefit Plans
The Company and its subsidiaries have pension plans covering the majority of eligible employees on a contributory or non-contributory basis. The Company also provides postretirement health care and life insurance benefits for the majority of its U.S. retired employees. Disclosures for the U.S. plans have been combined with those outside of the U.S. as the international plans do not have significantly different assumptions, and together represent less than 21% of our total benefit obligation.

Note 13. Accounting for Asset Retirement Obligations
The Company records asset retirement obligations for situations in which the Company will be required to incur costs to retire tangible long-lived assets. The fair value of the liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made.
The Company also records liabilities related to land reclamation as a part of asset retirement obligations. The Company mines various minerals using a surface mining process that requires the removal of overburden. In certain areas and under various governmental regulations, the Company is obligated to restore the land comprising each mining site to its original condition at the completion of the mining activity. The obligation is adjusted to reflect the passage of time, mining activities, and changes in estimated future cash outflows.
The asset retirement costs are capitalized as part of the carrying amount of the associated asset. The current portion of the liability of approximately $0.4 million is included in other current liabilities and the long-term portion of the liability of approximately $23.2 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheet as of June 28, 2020.
Note 14. Contingencies
The Company is party to a number of lawsuits arising in the normal course of our business.
Certain of the Company's subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing materials. As of June 28, 2020, the Company currently has three pending silica cases and 176 pending asbestos cases. In total, 1,493 silica cases and 83 asbestos cases were dismissed as of the end of the first quarter, not including any lawsuits against AMCOL or American Colloid Company dismissed prior to our acquisition of AMCOL. Forty-six new asbestos cases were filed in the second quarter of 2020. Five asbestos cases and no silica cases were dismissed during the second quarter of 2020. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any. Additional claims of this nature may be made against the Company or its subsidiaries. At this time management anticipates that the amount of the Company's liability, if any, and the cost of defending such claims, will not have a material effect on its financial position or results of operations.
16

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
The Company has settled only one silica lawsuit, for a nominal amount, and no asbestos lawsuits to date (not including any that may have been settled by AMCOL prior to completion of the acquisition). We are unable to state an amount or range of amounts claimed in any of the lawsuits because state court pleading practices do not require identifying the amount of the claimed damage. The aggregate cost to the Company for the legal defense of these cases since inception continues to be insignificant. The majority of the costs of defense for these cases, excluding cases against AMCOL or American Colloid, are reimbursed by Pfizer Inc. pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992. The Company is entitled to indemnification, pursuant to agreement, for sales prior to the initial public offering. Of the 176 pending asbestos cases as of the end of the second quarter, 136 of the non-AMCOL cases are subject to indemnification, in whole or in part, because the plaintiffs claim liability based on sales of products that occurred either entirely before the initial public offering, or both before and after the initial public offering. Thirty-three of the thirty-eight remaining non-AMCOL cases as of the end of the second quarter are subject to indemnity in part until dates of exposure, which were not alleged in the complaint, can be ascertained in discovery. In the five remaining non-AMCOL cases, exposure is alleged to have been after the Company's initial public offering in 1992. The remaining two cases involve AMCOL only, so no Pfizer indemnity is available. Our experience has been that the Company is not liable to plaintiffs in any of these lawsuits and the Company does not expect to pay any settlements or jury verdicts in these lawsuits.
The Company is also the respondent in an arbitration requested by the Plan Administrator for the Bankruptcy Estate of Novinda Corp. (“Novinda”), a start-up company which declared bankruptcy in April 2016 and with which the Company had several relationships, including an equity and debt interest and a product supply relationship. On July 30, 2018, the Plan Administrator filed a Demand for Arbitration against the Company and certain of its officers for the alleged destruction of Novinda’s business. In the second quarter of 2020, the arbitration panel rendered an award in the arbitration, finding for the Company in part and for Novinda in part. The total amount of the award has not yet been finalized. The Company has recorded a charge of $8.0 million related to this matter in the second quarter of 2020, representing its reasonable estimate of the damages, interest and costs awarded by the panel to Novinda. In addition, the Company has recorded a total of $11.8 million in litigation expense related to this matter, $ 0.9 million of which was recorded in 2020.
Environmental Matters
On April 9, 2003, the Connecticut Department of Environmental Protection issued an administrative consent order relating to our Canaan, Connecticut plant where both our Refractories segment and Specialty Minerals segment have operations. We agreed to the order, which includes provisions requiring investigation and remediation of contamination associated with historic use of polychlorinated biphenyls ("PCBs") and mercury at a portion of the site. We have completed the required investigations and submitted several reports characterizing the contamination and assessing site-specific risks. We are awaiting regulators’ approval of the risk assessment report, which will form the basis for a proposal by the Company concerning eventual remediation.
We believe that the most likely form of overall site remediation will be to leave the existing contamination in place (with some limited soil removal), encapsulate it, and monitor the effectiveness of the encapsulation. We anticipate that a substantial portion of the remediation cost will be borne by the United States based on its involvement at the site from 1942 – 1964, as historic documentation indicates that PCBs and mercury were first used at the facility at a time of U.S. government ownership for production of materials needed by the military. Pursuant to a Consent Decree entered on October 24, 2014, the United States paid the Company $2.3 million in the 4th quarter of 2014 to resolve the Company’s claim for response costs for investigation and initial remediation activities at this facility through October 24, 2014. Contribution by the United States to any future costs of investigation or additional remediation has, by agreement, been left unresolved. Though the cost of the likely remediation remains uncertain pending completion of the phased remediation decision process, we have estimated that the Company’s share of the cost of the encapsulation and limited soil removal described above would approximate $0.4 million, which has been accrued as of June 28, 2020.
The Company is evaluating options for upgrading the wastewater treatment facilities at its Adams, Massachusetts plant. This work has been undertaken pursuant to an administrative Consent Order originally issued by the Massachusetts Department of Environmental Protection (“DEP”) on June 18, 2002. This order was amended on June 1, 2009 and on June 2, 2010. The amended Order includes the investigation by January 1, 2022 of options for ensuring that the facility's wastewater treatment ponds will not result in unpermitted discharge to groundwater. Additional requirements of the amendment include the submittal by July 1, 2022 of a plan for closure of a historic lime solids disposal area. Preliminary engineering reviews completed in 2005 indicate that the estimated cost of wastewater treatment upgrades to operate this facility beyond 2024 may be between $6 million and $8 million. The Company estimates that the remaining remediation costs would approximate $0.4 million, which has been accrued as of June 28, 2020.

Note 16. Subsequent Event
On June 30, 2020, the Company issued $400 million aggregate principal amount of 5.0% Senior Notes due 2028 (the "Notes"). The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. The Company used the net proceeds of its offering of the Notes to repay all of its outstanding loans under the fixed rate tranche of the Term Facility, repay all of its outstanding borrowings under its Revolving Credit Facility, and the remainder for general corporate purposes
The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company's existing and future wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company's obligations under its Senior Secured Credit Facilities or that guarantees the Company's or any of the Company's wholly owned domestic subsidiaries’ long-term indebtedness in an aggregate amount in excess of $50 million.
At any time and from time to time prior to July 1, 2023, the Company may redeem some or all of the Notes for cash at a redemption price equal to 100% of their principal amount, plus the “make-whole” premium described in the Indenture and accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Beginning on July 1, 2023, the Company may redeem some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time and from time to time prior to July 1, 2023, the Company may redeem up to 40% of the aggregate principal amount of the Notes with funds from one or more equity offerings at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.
If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase the Notes at 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.
The indenture contains certain customary affirmative and negative covenants that limit or restrict the ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions, as well as customary events of default.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and Board of Directors
Minerals Technologies Inc.:
Results of Review of Interim Financial Information
We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiaries (the Company) as of June 28, 2020, the related condensed consolidated statements of income and comprehensive income for the three-month and six-month periods ended June 28, 2020 and June 30, 2019, the related condensed consolidated statements of cash flows for the six-month periods ended June 28, 2020 and June 30, 2019, the related condensed statements of changes in shareholders' equity for the three-month periods ended June 28 and March 29, 2020 and June 30 and March 31, 2019, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2019, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 14, 2020, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2019, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
Basis for Review Results
This consolidated interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
Executive Summary
Our consolidated sales for the second quarter of 2020 were $357.2 million, as compared with $463.8 million in the prior year. Income from operations was $27.2 million and represented 7.6% of sales, as compared with $45.5 million and 9.8% of sales in the prior year. Included in income from operations for the second quarter of 2020 were $6.5 million of restructuring and other items. In addition, we recorded $8.3 million of litigation expenses associated with the bankruptcy of Novinda Corp, including an $8.0 million estimated amount of damages, interest and costs awarded to Novinda. Net income was $14.4 million, as compared to $26.6 million in the second quarter of 2019. Diluted earnings in the second quarter ended June 28, 2020 were $0.42 per share, as compared with $0.75 per share in 2019.
In March 2020, the World Health Organization categorized the novel coronavirus (COVID-19) as a pandemic. We have remained focused on the health and safety of our employees, and deployed rigorous health, safety and wellness protocols for all of our facilities in order to protect our employees. We have also conducted scenario planning and developed contingency plans to ensure we are supporting our customers and adjusting to changing market dynamics. Around the world, the Company continues to closely adhere to all government regulations as they are issued. Applicable governmental directives across the United States and other global locations have typically permitted the continued operation of essential critical infrastructure sectors. As the Company supplies products and services to many essential industries, including critical manufacturing and energy sectors, all of our operations had qualified as essential businesses. Accordingly, all of the Company’s production facilities are currently operational. In a few locations, however, sites were temporarily impacted by the pandemic.
The recent economic environment related to the rapidly evolving global pandemic, which has slowed business activity in several key end-markets, negatively impacted the Company’s second quarter results. The pandemic has affected and we expect will continue to affect the demand for a number of our Performance Materials segment’s products and services. We expect paper consumption to be down in the next quarter. Global steel production has been and will continue to be affected by volatility in the market due to the COVID-19 pandemic and we expect steel consumption to be lower due to delays in the construction and automotive industries, which will impact our Refractory segment. Oil and natural gas prices have decreased significantly as a result of the COVID-19 pandemic, which, if sustained, will continue to cause oil and natural gas companies to reduce their capital expenditures and production and exploration activities.
We expect the impacts of the COVID-19 pandemic to continue to impact our results for the third quarter. The extent to which our operations will be impacted by the pandemic will depend largely on future developments, including the continued severity of the pandemic and future actions by government authorities to contain it or treat its impact. These conditions are highly uncertain and cannot be accurately predicted. We will continue to actively monitor and respond to the COVID-19 pandemic. We are actively managing the business to maintain cash flow.
Our balance sheet continues to be strong. Cash, cash equivalents and short-term investments were $238.2 million as of June 28, 2020. On June 30, 2020, the Company completed a $400 million private offering of senior unsecured notes due 2028. The net proceeds were used to repay $148 million of fixed rate term loans and $100 million of outstanding borrowing under its revolving credit facility and the remainder for general corporate purposes. As a result, the Company currently has more than $650 million of available liquidity, including cash on hand as well as availability under its revolving credit facility. We believe that these factors will allow us to meet our anticipated funding requirements.
Outlook
The COVID-19 pandemic had a material adverse effect on our reported results for our second quarter, and we expect it will negatively impact our business and results of operations for our third quarter. The extent to which our operations will be impacted by the pandemic will depend largely on future developments, including the severity of the pandemic and actions by government authorities to contain it or treat its impact. These are highly uncertain and cannot be accurately predicted. We will continue to actively monitor and respond to the COVID-19 pandemic.
The Company will also continue to focus on innovation and new product development and other opportunities for sales growth from our existing businesses in 2020, as follows:

| ● | Increase our presence and gain penetration of our bentonite-based foundry customers for the Metalcasting industry in emerging markets, such as China and India.

| ● | Increase our presence and market share in global pet care products, particularly in emerging markets.

| ● | Deploy new products in pet care such as lightweight litter.

| ● | Increase our presence and market share in Asia and in the global powdered detergent market.

| ● | Continue the development of our proprietary Enersol® products for agricultural applications worldwide.

| ● | Pursue opportunities for our products in environmental and building and construction markets in the Middle East, Asia Pacific and South America regions.

| ● | Increase our presence and market share for geosynthetic clay liners within the Environmental Products product line.

| ● | Develop multiple high-filler technologies under the FulFill® platform of products, to increase the fill rate in freesheet paper and continue to progress with commercial discussions and full-scale paper machine trials.

| ● | Develop products and processes for waste management and recycling opportunities to reduce the environmental impact of the paper mill, reduce energy consumption and improve the sustainability of the papermaking process, including our NewYield® and ENVIROFIL® products.

| ● | Further penetration into the packaging segment of the paper industry.

| ● | Increase our sales of PCC for paper by further penetration of the markets for paper filling at both freesheet and groundwood mills, particularly in emerging markets.

| ● | Expand the Company's PCC coating product line using the satellite model.

| ● | Promote the Company's expertise in crystal engineering, especially in helping papermakers customize PCC morphologies for specific paper applications.

| ● | Expand PCC produced for paper filling applications by working with industry partners to develop new methods to increase the ratio of PCC for fiber substitutions.

| ● | Develop unique calcium carbonate and talc products used in the manufacture of novel biopolymers, a new market opportunity.

| ● | Deploy new talc and GCC products in paint, coating and packaging applications.

| ● | Deploy value-added formulations of refractory materials that not only reduce costs but improve performance.

| ● | Deploy our laser measurement technologies into new applications.

| ● | Expand our refractory maintenance model to other steel makers globally.

| ● | Increase our presence and market penetration in offshore produced water and offshore filtration and well testing within the Energy Services segment.

| ● | Deploy operational excellence principles into all aspects of the organization, including system infrastructure and lean principles.

| ● | Continue to explore selective acquisitions to fit our core competencies in minerals and fine particle technology.

However, there can be no assurance that we will achieve success in implementing any one or more of these opportunities.

Worldwide net sales decreased 23% to $357.2 million in the second quarter from $463.8 million in the prior year. Foreign exchange had an unfavorable impact on sales of approximately $9.9 million or 2%. Sales decreased in all business segments primarily due to reduced volumes related to the impacts of the COVID-19 pandemic.
Net sales in the United States decreased 29% to $180.7 million from $253.3 million in the prior year. International sales decreased 16% to $176.5 million from $210.5 million in the prior year.
Operating Costs and Expenses
Cost of sales was $268.3 million and represented 75.1% of sales for the three month period ended June 28, 2020, as compared with $351.8 million and 75.9% of sales in the prior year. Production margin increased from 24.1% of sales in the prior year to 24.9% of sales in the second quarter of 2020. This improvement was primarily due to favorable mix, higher selling prices and cost control.
Marketing and administrative costs were $41.8 million and 11.7% of sales for the three months ended June 28, 2020, as compared to $48.4 million and 10.4% of sales in the prior year. The decrease was primarily due to lower expenses as a result of the pandemic. Included in marketing and administrative costs for the three months ended June 30, 2019 was bad debt expense of $2.5 million relating to a refractories customer bankruptcy in the U.K.
Research and development expenses were $5.1 million and represented 1.4% of sales for the three months ended June 28, 2020, as compared with $4.9 million and 1.1% of sales in the prior year.

Other Non-Operating Income (Deductions)
In the second quarter of 2020, non-operating deductions were $12.6 million as compared with $13.3 million in the prior year. The decrease was primarily related to lower interest expense in the quarter as compared with prior year due to lower interest rates and lower debt levels. Included in other non-operating deductions for the second quarter of 2020 is a $4.3 million non-cash pension settlement charge associated with our plans in the U.S.
Provision for Taxes on Income
Provision for taxes on income was $0.9 million and $5.1 million for the three months ended June 28, 2020 and June 30, 2019, respectively. The effective tax rate was 6.2% and 15.8% for the three months ended June 28, 2020 and June 30, 2019, respectively. The lower effective tax rate was primarily due to discrete items related to restructuring and other charges and to the mix of earnings.
Consolidated Net Income Attributable to MTI Shareholders
Consolidated net income was $14.4 million for the three months ended June 28, 2020, as compared with $26.6 million in the prior year.

Sales in Metalcasting decreased 30% from prior year primarily driven by COVID-19 related automotive production slowdown in North American and parts of Asia. Metalcasting sales in China grew 9%, as economic activity rebounded following the COVID-19 related shutdowns, and we continued to penetrate the market with our pre-blended greensand bond formulations. Household, Personal Care & Specialty Products sales decreased 4% as compared with prior year. We saw continued strong performance from our global pet care business, which grew 3%, as well as fabric care, which grew 20%, and personal care, which grew 7%. The growth in these consumer-oriented businesses was offset by weakness in specialty drilling products. Environmental Products and Building Materials sales both decreased 31% primarily due to COVID-19 related project delays.
Income from operations was $21.0 million and 12.1% of sales as compared to $20.7 million and 9.6% of sales in the prior year. Included in income from operations for the three month period ended June 30, 2019 were $7.0 million of restructuring and impairment costs. The impact of lower sales on operating income versus the prior year was partially mitigated by expense control, input cost reductions, and continued pricing actions.

On May 9, 2014, in connection with the acquisition of AMCOL International Corporation (“AMCOL”), the Company entered into a credit agreement providing for the $1.560 billion senior secured term loan facility (the “Term Facility”) and a $200 million senior secured revolving credit facility.
30

On June 23, 2015, the Company entered into an amendment (the “First Amendment”) to the credit agreement to reprice the $1.378 billion then outstanding on the Term Facility. As amended, the Term Facility had a $1.078 billion floating rate tranche and a $300 million fixed rate tranche. On February 14, 2017, the Company entered into an amendment (the “Second Amendment”) to the credit agreement to reprice the $788 million floating rate tranche then outstanding, which extended the maturity and lowered the interest costs by 75 basis points. On April 18, 2018, the Company entered into an amendment (the “Third Amendment”) to the credit agreement to refinance its then existing senior secured revolving credit facility. In connection with the Third Amendment, the existing senior secured revolving credit facility was replaced with a new revolving credit facility with $300 million of aggregate commitments (the “Revolving Credit Facility” and, together with the Term Facility, the “Senior Secured Credit Facilities”). Following the amendments, the loans outstanding under the floating rate tranche of the Term Facility are scheduled to mature on February 14, 2024, the loans outstanding under the fixed rate tranche of the Term Facility are scheduled to mature on May 9, 2021 and the loans outstanding (if any) and commitments under the Revolving Facility will mature and terminate, as the case may be, on April 18, 2023. Loans under the floating rate tranche of the Term Facility bear interest at a rate equal to an adjusted LIBOR rate (subject to a floor of 0.75%) plus an applicable margin equal to 2.25% per annum. Loans under the fixed rate tranche of the Term Facility bear interest at a rate of 4.75%. Loans under the Revolving Facility bear interest at a rate equal to an adjusted LIBOR rate plus an applicable margin equal to 1.625% per annum. Such rates are subject to decrease by up to 25 basis points in the event that, and for so long as, the Company’s net leverage ratio (as defined in the credit agreement) is less than certain thresholds. The floating rate tranche of the Term Facility was issued at par and the fixed rate tranche of the Term Facility was issued at a 0.25% discount in connection with the First Amendment. The variable rate tranche of the Term Facility was issued at a 0.25% discount in connection with the Second Amendment. The variable rate tranche has a 1% required amortization per year. The Company will pay certain fees under the credit agreement, including customary annual administration fees. The obligations of the Company under the Senior Secured Credit Facilities are unconditionally guaranteed jointly and severally by, subject to certain exceptions, all material domestic subsidiaries of the Company (the “Guarantors”) and secured, subject to certain exceptions, by a security interest in substantially all of the assets of the Company and the Guarantors.
On June 30, 2020, the Company issued $400 million aggregate principal amount of 5.0% Senior Notes due 2028 (the "Notes"). The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. The Company used the net proceeds of its offering of the Notes to repay all of its outstanding loans under the fixed rate tranche of the Term Facility, repay all of its outstanding borrowings under its Revolving Credit Facility, and the remainder for general corporate purposes
The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company's existing and future wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company's obligations under its Senior Secured Credit Facilities or that guarantees the Company's or any of the Company's wholly owned domestic subsidiaries’ long-term indebtedness in an aggregate amount in excess of $50 million.
At any time and from time to time prior to July 1, 2023, the Company may redeem some or all of the Notes for cash at a redemption price equal to 100% of their principal amount, plus the “make-whole” premium described in the Indenture and accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Beginning on July 1, 2023, the Company may redeem some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time and from time to time prior to July 1, 2023, the Company may redeem up to 40% of the aggregate principal amount of the Notes with funds from one or more equity offerings at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.
If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase the Notes at 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.
The credit agreement and the Notes contain certain customary affirmative and negative covenants that limit or restrict the ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions. In addition, the credit agreement contains a financial covenant that requires the Company, if on the last day of any fiscal quarter loans or letters of credit were outstanding under the Revolving Facility (excluding up to $25 million of letters of credit), to maintain a maximum net leverage ratio (as defined in the credit agreement) of 3.50 to 1.00 for the four fiscal quarter periods preceding such day. In connection with the Sivomatic acquisition, the Company incurred $113.0 million of short-term debt under the Revolving Facility. As of June 28, 2020, there were $100 million in outstanding loans and $9.4 million in letters of credit outstanding under the Revolving Facility. The Company is in compliance with all the covenants associated with the Revolving Facility as of the end of the period covered by this report.
31

As part of the Sivomatic acquisition, the Company assumed $10.7 million in long term debt, recorded at fair value, consisting of two term loans, one of which matures in 2020 and the other of which matures in 2022. In the first quarter of 2020, the Company repaid $1.0 million on these loans.
The Company has a committed loan facility in Japan. As of June 28, 2020, $4.3 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2021. The Company repaid $0.3 million on this facility during the first half of 2020.
As of June 28, 2020, the Company had $41.8 million in uncommitted short-term bank credit lines, of which approximately $0.3 million was in use. The credit lines are primarily outside the U.S. and are generally one year in term at competitive market rates at large, well-established institutions. The Company typically uses its available credit lines to fund working capital requirements or local capital spending needs. We anticipate that capital expenditures for 2020 should be between $55 million and $65 million, principally related to the construction of PCC plants and other opportunities that meet our strategic growth objectives. We expect to meet our other long-term financing requirements from internally generated funds, committed and uncommitted bank credit lines and, where appropriate, project financing of certain satellite plants.
On April 5, 2016, the Company entered into a floating to fixed interest rate swap for an initial aggregate notional amount of $300 million to limit exposure to interest rate increases related to a portion of the Company’s floating rate indebtedness. This swap agreement hedges a portion of contractual floating rate interest through its expiration in May 2021. As a result of the agreement, the Company’s effective fixed interest rate on the notional amount floating rate indebtedness will be 4.25%. The fair value of this instrument at June 28, 2020 was a liability of $0.2 million.
During the second quarter of 2018, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. Additionally, the Company entered into a cross currency rate swap with a total notional value of $150 million to exchange monthly fixed-rate interest payments in U.S. dollars for monthly fixed-rate interest rate payments in Euros. These swaps mature in May 2023. As a result of these swaps, the Company’s effective fixed interest rate on the notional floating rate indebtedness will be 2.5%. The combined fair value of these instruments at June 28, 2020 was an asset of $5.9 million.
On October 23, 2019, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $75 million of the Company's shares over a one-year period. As of June 28, 2020, 851,258 shares have been repurchased under this program for $42.6 million, or an average price of approximately $50.00 per share. There were no share repurchases in the second quarter of 2020.
The Company is required to make future payments under various contracts, including debt agreements and lease agreements. The Company also has commitments to fund its pension plans and provide payments for other postretirement benefit plans. During the six months ended June 28, 2020, there were no material changes in the Company’s contractual obligations. For an in-depth discussion of the Company's contractual obligations, see "Liquidity and Capital Resources" in "Management's Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
As we cannot predict the duration or scope of the COVID-19 pandemic and its impact on our customers and suppliers, the negative financial impact to our results cannot be reasonably estimated, but could be material. We are actively managing the business to maintain cash flow and we have significant liquidity. We believe that these factors will allow us to meet our anticipated funding requirements.
Cautionary Statement for “Safe Harbor” Purposes under the Private Securities Litigation Reform Act of 1995
The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements made by or on behalf of the Company. This report contains statements that the Company believes may be “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, particularly statements relating to the Company’s objectives, plans or goals, future actions, future performance or results of current and anticipated products, sales efforts, expenditures, and financial results. From time to time, the Company also provides forward-looking statements in other publicly-released materials, both written and oral. Forward-looking statements provide current expectations and forecasts of future events such as new products, revenues and financial performance, and are not limited to describing historical or current facts. They can be identified by the use of words such as “believes,” “expects,” “plans,” “intends,” “anticipates,” and other words and phrases of similar meaning.
32

Forward-looking statements are necessarily based on assumptions, estimates and limited information available at the time they are made. A broad variety of risks and uncertainties, both known and unknown, as well as the inaccuracy of assumptions and estimates, can affect the realization of the expectations or forecasts in these statements. Many of these risks and uncertainties are difficult to predict or are beyond the Company’s control. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially. Significant factors that could affect the expectations and forecasts include the duration and scope of the COVID-19 pandemic, and government and other third-party responses to it; worldwide general economic, business, and industry conditions, including the effects of the COVID-19 pandemic on the global economy; the cyclicality of our customers’ businesses and their changing demands; the dependence of certain of our product lines on the commercial construction and infrastructure markets, the domestic building and construction markets, and the automotive market; our ability to effectively achieve and implement our growth initiatives; our ability to service our debt; our ability to comply with the covenants in the agreements governing our debt; our ability to renew or extend long term sales contracts for our PCC satellite operations; consolidation in customer industries, principally paper, foundry and steel; compliance with or changes to regulation in the areas of environmental, health and safety, and tax; claims for legal, environmental and tax matters or product stewardship issues; our ability to successfully develop new products; our ability to ability to defend our intellectual property; the increased risks of doing business abroad; the availability of raw materials and access to ore reserves at our mining operations; increases in costs of raw materials, energy, or shipping; our ability to compete in very competitive industries; operating risks and capacity limitations affecting our production facilities; seasonality of some of our segments; cybersecurity and other threats relating to our information technology systems; and other risks set forth under “Item 1A — Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, and in Exhibit 99 to this Quarterly Report on Form 10-Q.
The Company undertakes no obligation to update any forward-looking statements to reflect events or circumstances that arise after the date hereof. Investors should refer to the Company's subsequent filings under the Securities Exchange Act of 1934 for further disclosures.
Recently Issued Accounting Standards
Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of operations.
Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging
In January 2020, the FASB issued ASU 2020-01, "Investments - Equity Securities, Investments - Equity Method and Joint Ventures, and Derivatives and Hedging", which addresses the accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The standard is effective for interim and annual periods beginning on or after December 15, 2020. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Recently Adopted Accounting Standards
Measurement of Credit Losses on Financial Instruments
In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments", which replaces existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost. The Company adopted this guidance on January 1, 2020 using a modified retrospective transition method. The Company did not record a cumulative-effect adjustment upon adoption of this standard. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Critical Accounting Policies
Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.
On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, valuation of long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances and pension plan assumptions. We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that cannot readily be determined from other sources. There can be no assurance that actual results will not differ from those estimates.
33

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk
Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in market prices and foreign currency and interest rates. We are exposed to market risk because of changes in foreign currency exchange rates as measured against the U.S. dollar. We do not anticipate that near-term changes in exchange rates will have a material impact on our future earnings or cash flows. However, there can be no assurance that a sudden and significant decline in the value of foreign currencies would not have a material adverse effect on our financial condition and results of operations. A portion of our long-term bank debt bears interest at variable rates; therefore, our results of operations would be affected by interest rate changes to the extent of such outstanding bank debt. An immediate 10 percent change in interest rates would have a material effect on our results of operations over the next fiscal year. A one-percent change in interest rates, inclusive of the impact of our interest rate derivatives, would result in $2.0 million in incremental interest charges on an annual basis.
We do not enter into derivatives or other financial instruments for trading or speculative purposes. When appropriate, we enter into derivative financial instruments, such as forward exchange contracts, hedges and interest rate swaps, to mitigate the impact of foreign exchange rate movements and interest rate movements on our operating results. The counterparties are major financial institutions. Such forward exchange contracts, hedges and interest rate swaps would not subject us to additional risk from exchange rate or interest rate movements because gains and losses on these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged.
On April 5, 2016, the Company entered into a floating to fixed interest rate swap for an initial aggregate notional amount of $300 million to limit exposure to interest rate increases related to a portion of the Company’s floating rate indebtedness. This swap agreement hedges a portion of contractual floating rate interest through its expiration in May 2021. As a result, the Company’s effective fixed interest rate on the notional amount floating rate indebtedness will be 4.25% through May 2021. The fair value of this instrument at June 28, 2020 was a liability of $0.2 million.
During the second quarter of 2018, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. Additionally, the Company entered into a cross currency rate swap with a total notional value of $150 million to exchange monthly fixed-rate interest payments in U.S. dollars for monthly fixed-rate interest rate payments in Euros. These swaps mature in May 2023. As a result of these swaps, the Company’s effective fixed interest rate on the notional floating rate indebtedness will be 2.5%. The combined fair value of these instruments at June 28, 2020 was an asset of $5.9 million.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this report, and under the supervision and with participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of the end of the period covered by this report the Company’s disclosure controls and procedures were effective.
Changes in Internal Control Over Financial Reporting
There were no changes in the Company's internal controls over financial reporting during the quarter ended June 28, 2020 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
34

PART II – OTHER INFORMATION
Item 1. Legal Proceedings
The Company and its subsidiaries are the subject of various pending legal actions in the ordinary course of their businesses. Except as described below, none of such legal proceedings are material.
Silica and Asbestos Litigation
Certain of the Company's subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing materials. As of June 28, 2020, the Company currently has three pending silica cases and 176 pending asbestos cases. In total, 1,493 silica cases and 83 asbestos cases were dismissed as of the end of the second quarter, not including any lawsuits against AMCOL or American Colloid Company dismissed prior to our acquisition of AMCOL. Forty-six new asbestos cases were filed in the second quarter of 2020. Five asbestos cases and no silica cases were dismissed during the second quarter of 2020. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any. Additional claims of this nature may be made against the Company or its subsidiaries. At this time management anticipates that the amount of the Company's liability, if any, and the cost of defending such claims, will not have a material effect on its financial position or results of operations.
The Company has settled only one silica lawsuit, for a nominal amount, and no asbestos lawsuits to date (not including any that may have been settled by AMCOL prior to completion of the acquisition). We are unable to state an amount or range of amounts claimed in any of the lawsuits because state court pleading practices do not require identifying the amount of the claimed damage. The aggregate cost to the Company for the legal defense of these cases since inception continues to be insignificant. The majority of the costs of defense for these cases, excluding cases against AMCOL or American Colloid, are reimbursed by Pfizer Inc. pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992. The Company is entitled to indemnification, pursuant to agreement, for sales prior to the initial public offering. Of the 176 pending asbestos cases as of the end of the second quarter, 136 of the non-AMCOL cases are subject to indemnification, in whole or in part, because the plaintiffs claim liability based on sales of products that occurred either entirely before the initial public offering, or both before and after the initial public offering. In 33 of the 38 remaining non-AMCOL cases as of the end of the first quarter are subject to indemnity in part until dates of exposure, which were not alleged in the complaint, can be ascertained in discovery. In the five remaining non-AMCOL cases, exposure is alleged to have been after the Company's initial public offering in 1992. The remaining two cases involve AMCOL only, so no Pfizer indemnity is available. Our experience has been that the Company is not liable to plaintiffs in any of these lawsuits and the Company does not expect to pay any settlements or jury verdicts in these lawsuits.
Other Litigation
The Company is also the respondent in an arbitration requested by the Plan Administrator for the Bankruptcy Estate of Novinda Corp. (“Novinda”), a start-up company which declared bankruptcy in April 2016 and with which the Company had several relationships, including an equity and debt interest and a product supply relationship. On July 30, 2018, the Plan Administrator filed a Demand for Arbitration against the Company and certain of its officers for the alleged destruction of Novinda’s business. In the second quarter of 2020, the arbitration panel rendered an award in the arbitration, finding for the Company in part and for Novinda in part. The total amount of the award has not yet been finalized. The Company has recorded a charge of $8.0 million related to this matter in the second quarter of 2020, representing its reasonable estimate of the damages, interest and costs awarded by the panel to Novinda. In addition, the Company has recorded a total of $11.8 million in litigation expense related to this matter, $0.9 million of which were recorded in 2020.
Environmental Matters
On April 9, 2003, the Connecticut Department of Environmental Protection issued an administrative consent order relating to our Canaan, Connecticut plant where both our Refractories segment and Specialty Minerals segment have operations. We agreed to the order, which includes provisions requiring investigation and remediation of contamination associated with historic use of polychlorinated biphenyls ("PCBs") and mercury at a portion of the site. We have completed the required investigations and submitted several reports characterizing the contamination and assessing site-specific risks. We are awaiting regulators’ approval of the risk assessment report, which will form the basis for a proposal by the Company concerning eventual remediation.
35

We believe that the most likely form of overall site remediation will be to leave the existing contamination in place (with some limited soil removal), encapsulate it, and monitor the effectiveness of the encapsulation. We anticipate that a substantial portion of the remediation cost will be borne by the United States based on its involvement at the site from 1942 – 1964, as historic documentation indicates that PCBs and mercury were first used at the facility at a time of U.S. government ownership for production of materials needed by the military. Pursuant to a Consent Decree entered on October 24, 2014, the United States paid the Company $2.3 million in the 4th quarter of 2014 to resolve the Company’s claim for response costs for investigation and initial remediation activities at this facility through October 24, 2014. Contribution by the United States to any future costs of investigation or additional remediation has, by agreement, been left unresolved. Though the cost of the likely remediation remains uncertain pending completion of the phased remediation decision process, we have estimated that the Company’s share of the cost of the encapsulation and limited soil removal described above would approximate $0.4 million, which has been accrued as of June 28, 2020.
The Company is evaluating options for upgrading the wastewater treatment facilities at its Adams, Massachusetts plant. This work has been undertaken pursuant to an administrative Consent Order originally issued by the Massachusetts Department of Environmental Protection (“DEP”) on June 18, 2002. This order was amended on June 1, 2009 and on June 2, 2010. The amended Order includes the investigation by January 1, 2022 of options for ensuring that the facility's wastewater treatment ponds will not result in unpermitted discharge to groundwater. Additional requirements of the amendment include the submittal by July 1, 2022 of a plan for closure of a historic lime solids disposal area. Preliminary engineering reviews completed in 2005 indicate that the estimated cost of wastewater treatment upgrades to operate this facility beyond 2024 may be between $6 million and $8 million. The Company estimates that the remaining remediation costs would approximate $0.4 million, which has been accrued as of June 28, 2020.
The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses.
ITEM 1A. Risk Factors
For a description of Risk Factors, see Exhibit 99 attached to this report. There have been no material changes to our risk factors from those disclosed in our 2019 Annual Report on Form 10-K, except for the following:
We have been and expect to continue to be adversely affected by the recent COVID-19 outbreak.
The COVID-19 outbreak, declared a pandemic by the World Health Organization, has surfaced in nearly all regions around the world. Governments around the world have taken preventative measures to contain or mitigate the outbreak, including travel restrictions, border closings, restrictions on public gatherings, shelter-in-place restrictions and limitations on business. This has affected, and is continuing to affect, the global economy, the United States economy and the global financial markets. The outbreak and resulting preventative measures have disrupted our operations and affected our business, and we expect this to continue. The impacts include, but are not limited to, the following:

| ● | We have experienced, and expect to experience in the future, temporary facility closures in response to government mandates in certain jurisdictions in which we operate. We may also be required to close certain of our facilities for the safety of our employees in response to positive diagnoses for COVID-19. Even in facilities that are not closed, we could be affected by reductions in employee availability and effectiveness, changes in operating procedures, and increased costs.

| ● | Our customers have been, and may continue to be, affected by COVID-19 and the business slowdown caused by preventative measures, resulting in decreased demand for our products and services, delayed payments from customers and uncollectable accounts.

| ● | Our supply chain could be disrupted. This could materially adversely impact our ability to secure raw materials and supplies for our facilities, which could materially adversely affect our operations.

| ● | Significant disruption of global financial markets could have a negative impact on our ability to access capital in the future.

| ● | Further or prolonged impact from COVID-19 could result in impairment of asset charges, including long-lived or intangible assets, inventory or bad debt charges.

We cannot predict the degree to which, or the time period that, global economic conditions and our business, sales, liquidity, financial condition and results of operations will continue to be affected by the COVID-19 pandemic and the resulting preventative measures. The extent to which we are affected will depend on future developments, including the duration of the outbreak, travel restrictions, business and workforce disruptions, and the effectiveness of actions taken to contain and treat the disease. The effects on our business, sales, liquidity, financial condition and results of operations could be material.
36

Our customers’ businesses are cyclical or have changing regional demands. Our operations are subject to these trends and we may not be able to mitigate these risks.
Our Performance Materials segment’s sales are predominantly derived from the metalcasting market. The metalcasting market is dependent upon the demand for castings for automobile components, farm and construction equipment, oil and gas production equipment, power generation turbine castings, and rail car components. Many of these types of equipment are sensitive to fluctuations in demand during periods of recession or difficult economic conditions, including the current conditions resulting from the COVID-19 pandemic, which has affected and we expect will continue to affect the demand for our Performance Materials segment’s products and services.
In the paper industry, which is served by our Paper PCC product line, production levels for uncoated freesheet within North America and Europe, our two largest markets are projected to continue to decrease. The reduced demand for premium writing paper products has also caused recent paper mill closures. We expect paper consumption to be down in the next quarter as a result of the COVID-19 pandemic.
Our Refractories segment primarily serves the steel industry. Global steel production has been and will continue to be affected by volatility in the market due to the COVID-19 pandemic. We expect steel consumption to be lower due to delays in the construction and automotive industries.
Demand for our Energy Services segment’s products and services is affected by the level of exploration, development, and production activity of, and the corresponding capital spending by, oil and natural gas companies, which are heavily influenced by the benchmark price of these commodities. Oil and natural gas prices decreased significantly as a result of the COVID-19 pandemic with West Texas Intermediate (WTI) oil spot prices declining from a high of $63 per barrel in January 2020 to a low of $13 per barrel in April 2020. We expect the current decline, if sustained, will continue to cause oil and natural gas companies to reduce their capital expenditures and production and exploration activities. This has the effect of decreasing the demand and increasing competition for the services we provide. In addition, the performance of our Energy Services segment is affected by changes in technologies, locations of customers’ targeted reserves, and competition in various geographic markets.
Servicing the Company’s debt will require a significant amount of cash. This could reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditures or working capital needs. Our ability to generate cash depends on many factors beyond our control.
At June 28, 2020, on an as adjusted basis after giving effect to the transactions connected with our issuance of our 5.0% Senior Notes due 2028, the Company would have had $1,063.3 million aggregate principal amount of total indebtedness (consisting primarily of $658.0 million aggregate principal amount of loans under the fixed rate tranche of our term facility and $400.0 million aggregate principal amount of notes) and an additional $290.6 million of borrowing capacity under the revolving credit facility (after giving effect to $9.4 million of outstanding letters of credit). Our outstanding indebtedness will require a significant amount of cash to make interest payments. Further, the interest rate on a significant portion of our borrowings under our senior secured credit facility is based on LIBOR interest rates, which could result in higher interest expense in the event of an increase in interest rates. In addition, since these borrowings under our senior secured credit facility extend beyond 2021, the interest rates for these obligations might be subject to change based on the United Kingdom's Financial Conduct Authority's intention to phase out LIBOR by the end of 2021. Our ability to pay interest on our debt and to satisfy our other debt obligations will depend in part upon our future financial and operating performance and upon our ability to renew or refinance borrowings. Prevailing economic conditions and financial, business, competitive, regulatory and other factors, many of which are beyond our control, will affect our ability to make these payments. We cannot guarantee that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to fund our liquidity needs. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital. Further, the requirement to make significant interest payments may reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditure or working capital needs and may increase the Company’s vulnerability to adverse economic conditions.
37

The agreements and instruments governing our debt contain various covenants that could significantly impact our ability to operate our business.
The agreement governing our senior secured credit facility and the indenture that governs our 5.0% Senior Notes due 2028 contain a number of significant covenants that, among other things, limit our ability to: incur or guarantee additional indebtedness, pay dividends or make other distributions or repurchase or redeem capital stock, prepay, redeem or repurchase certain debt, issue certain preferred stock or similar equity securities, make loans and investments, sell or otherwise dispose of assets, incur liens, enter into transactions with affiliates, enter into agreements restricting our subsidiaries’ ability to pay dividends and consolidate, merge or sell all or substantially all of our assets. In addition, our revolving credit facility, if used, requires us to comply with specific financial ratios, including a maximum net leverage ratio, under which we are required to achieve specific financial results. Our ability to comply with these provisions may be affected by events beyond our control. A breach of any of these covenants would result in a default under the applicable agreements. In the event of any default under our senior secured credit facility, our lenders could elect to declare all amounts borrowed under the credit agreement, together with accrued interest thereon, to be due and payable. In such an event, we cannot assure you that we would have sufficient assets to pay debt then outstanding under the credit agreement, the indenture governing our notes, and any other agreements governing our debt. Any future refinancing of the senior secured credit facility is likely to contain similar restrictive covenants. We may also incur future debt obligations that might subject us to additional restrictive covenants that could affect our financial and operational flexibility. We cannot assure you that we will be granted waivers or amendments to these agreements if for any reason we are unable to comply with these agreements or that we will be able to refinance our debt on terms acceptable to us, or at all.
ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds
On October 23, 2019, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $75 million of the Company's shares over a one-year period. As of June 28, 2020, 851,258 shares have been repurchased under this program for $42.6 million, or an average price of approximately $50.00 per share. There were no share repurchases in the second quarter of 2020.
ITEM 3. Default Upon Senior Securities
Not applicable.
ITEM 4. Mine Safety Disclosures
The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this Quarterly Report on Form 10-Q.
