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, 2020. 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 nine-month periods ended October 3, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.
Company Operations
The Company is a resource- and technology-based company that develops, produces and markets worldwide a broad range of specialty minerals, mineral-based and synthetic mineral products and supporting systems and services.
In the first quarter of 2021, the Company reorganized the management structure for its Performance Materials and Energy Services operating segments into one operating segment, in order to support the Company's key growth initiatives, more closely align complementary technologies, processes and capabilities and better reflect the way performance is evaluated and resources are allocated.
The Company now has three reportable segments: Performance Materials, Specialty Minerals and Refractories.

– | 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 and remediation projects as well as offers a range of patented and unpatented technologies, products and services to the upstream and downstream oil and gas sector throughout the world.

– | 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.

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.

All recently issued ASUs 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.
Note 2. Revenue from Contracts with Customers
On a regular basis, the Company reviews its segments and the approach used by the chief operating decision maker to assess performance and allocate resources. Accordingly, in the first quarter of 2021, the Company reorganized the management structure for its Energy Services and Performance Materials operating segments to support MTI's key growth initiatives, more closely align complementary technologies, processes and capabilities, and better reflect the way performance is evaluated and resources are allocated. As a result, Energy Services, was combined into the Environmental Products product line within the Performance Materials operating segment. Restated financial results, by product line, of this operating segment for each quarter of 2020 to conform to the current management structure are presented in Note 15.
The following table disaggregates our revenue by major source (product line) for the three and nine-month periods ended October 3, 2021 and September 27, 2020:

Note 3. Acquisitions
On July 26, 2021, the Company completed the acquisition of Normerica Inc., a leading North American supplier of premium pet care products for approximately $188 million. Normerica has production facilities in Canada, the U.S. and Thailand. As a leader in the pet product industry, Normerica provides premium products, both branded and private label to world-class retailers. Its product portfolio consists primarily of bentonite-based cat litter products which are supplied from a network of strategically located manufacturing facilities in Canada and the United States. The results of Normerica are included within our Household, Personal Care & Specialty Products product line in our Performance Materials segment. Normerica has approximately 300 employees and generated revenue of $140 million in 2020. The acquisition was financed through a combination of cash on hand and the Company’s credit facilities. The fair value of the total consideration transferred, net of cash acquired, was $186.9 million.
The acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that we recognize the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. As of October 3, 2021, the purchase price allocation remains preliminary as the Company completes its assessment of property, certain reserves, legal and tax matters, obligations, intangible assets and deferred taxes, as well as completes its review of Normerica’s existing accounting policies.
The following table summarizes the Company's preliminary purchase price allocation for the Normerica acquisition:

(millions of dollars) |  | Preliminary Allocation |
Accounts receivable |  | $ | 8.4 |
Inventories |  |  | 5.1 |
Other current assets |  |  | 1.4 |
Property, plant and equipment |  |  | 21.2 |
Goodwill |  |  | 106.0 |
Intangible assets |  |  | 67.0 |
Total assets acquired |  |  | 209.1 |
Accounts payable |  |  | 12.8 |
Accrued expenses |  |  | 9.4 |
Total liabilities assumed |  |  | 22.2 |
Net assets acquired |  | $ | 186.9 |

The Company used the income, market, or cost approach (or a combination thereof) for the valuation and used valuation inputs and analyses that were based on market participant assumptions. Market participants are considered to be buyers and sellers unrelated to the Company in the principal or most advantageous market for the asset or liability. For certain items, the carrying value was determined to be a reasonable approximation of fair value based on the information available.
Goodwill was calculated as the excess of the consideration transferred over the assets acquired and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill is primarily attributable to fair value of expected synergies from combining the MTI and Normerica businesses and will be allocated to the Performance Materials segment. The allocation is expected to be completed during the second quarter of 2022.
Intangible assets acquired mainly include tradenames and customer relationships. Both tradenames and customer relationships have an estimated useful life of approximately 20 years.
The Company did not present pro forma and other financial information for the Normerica acquisition, as this is not considered to be a material business combination.
The Company incurred $1.5 million and $1.9 million of acquisition-related costs during the three-month and nine-month periods ended October 3, 2021, which are reflected within the acquisition-related expense line of the Condensed Consolidated Statements of Income.
In the third quarter of 2020, the Company acquired the assets of a mining and hauling company in the western United States for $9.2 million to support our bentonite clay mining operations.

Diluted earnings per share attributable to Minerals Technologies Inc. |  | $ | 1.22 |  |  | $ | 0.83 |  |  | $ | 3.63 |  |  | $ | 2.38 |

Of the options outstanding of 1,409,110 and 1,439,677 for the three-month and nine-month periods ended October 3, 2021 and September 27, 2020, respectively, options to purchase 526,956 shares and 1,054,428 shares of common stock for the three-month and nine-month periods ending October 3, 2021 and September 27, 2020, 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
In the third quarter of 2021, PCA Corporation discontinued the use of PCC at their mill in Jackson, Alabama. As a result, the Company recorded a non-cash asset write-down of $0.7 million and $0.4 million in severance related and other closure costs for its Paper PCC satellite facility at this mill.
In the third quarter of 2020, Domtar Corporation announced that they will permanently shut down their previously idled paper machine at their mill in Ashdown, Arkansas. As a result, the Company recorded a non-cash asset write-down of $1.1 million for its Paper PCC satellite facility at this mill.
In the second quarter of 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 Company also recorded lease termination costs at one of the closed mills.

At October 3, 2021, the Company had $2.4 million included within accrued liabilities in the Condensed Consolidated Balance Sheet for cash expenditures needed to satisfy remaining obligations under workforce reduction initiatives. The Company expects to pay these amounts by the end of 2021.
The following table is a reconciliation of our restructuring liability balance as of October 3, 2021:

(millions of dollars) |  |  |
Restructuring liability, December 31, 2020 |  | $ | $ 3.6 |
Additional provision |  |  | 0.1 |
Cash payments |  |  | (1.3 | )
Restructuring liability, October 3, 2021 |  | $ | $ 2.4 |

Note 6. Income Taxes
Provision for taxes was $8.9 million and $27.6 million during the three-month and nine-month periods ended October 3, 2021, respectively. Provision for taxes was $7.0 million and $17.6 million for the three-month and nine-month periods ended September 27, 2020. The effective tax rate was 17.6% for the three months ended October 3, 2021 as compared with 19.6% for the three months ended September 27, 2020. The lower tax rate was primarily due to a greater depletion benefit on higher sales as compared to the prior year.
As of October 3, 2021, the Company had approximately $7.2 million of total unrecognized income tax benefits. Included in this amount were a total of $4.6 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 during the three-month period ended October 3, 2021 and no change during the nine-month period ended October 3, 2021 and an accrued balance of $2.0 million of interest and penalties as of October 3, 2021.
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 $909.8 million and $808.5 million as of October 3, 2021 and December 31, 2020, respectively. The net change in goodwill from December 31, 2020 to October 3, 2021 is primarily attributable to the acquisition of Normerica (see Note 3 to the Condensed Consolidated Financial Statements) and to the effects of foreign exchange.
Intangible assets subject to amortization as of October 3, 2021 and December 31, 2020 were as follows:

|  |  |  |  | October 3, 2021 |  |  | December 31, 2020 |
(millions of dollars) |  | Weighted Average Useful Life (Years) |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |
Tradenames |  |  | 34 |  |  | $ | 219.9 |  |  | $ | 43.1 |  |  | $ | 203.9 |  |  | $ | 38.6 |
Technology |  |  | 13 |  |  |  | 18.8 |  |  |  | 10.8 |  |  |  | 18.8 |  |  |  | 9.6 |

|  |  | 31 |  |  | $ | 321.5 |  |  | $ | 67.5 |  |  | $ | 256.0 |  |  | $ | 60.2 |

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 31 years. Estimated amortization expense is $3.2 million for the remainder of 2021, $49.5 million for 2022–2025 and $201.3 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.
14

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 $5.2 million at October 3, 2021 and is recorded in other non-current liabilities on the Condensed Consolidated Balance Sheet. This interest rate swap is designated as a cash flow hedge. As a result, the gains and losses associated with this interest rate swap is 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 $6.9 million at October 3, 2021 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, 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 fixed rate tranche of the Term Facility were repaid in full in June 2020. 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 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 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 Normerica acquisition, the Company incurred $100 million of short-term debt under the Revolving Facility. As of October 3, 2021, there were $100.0 million in loans and $10.7 million in letters of credit outstanding under the Revolving Facility. The Company is in compliance with all the covenants associated with the Revolving Facility throughout the period covered by this report.
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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
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% 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.
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 matured in the third quarter of 2020 and the other of which matures in 2022. This loan carries an interest rate of Euribor plus 2.0% and has quarterly repayments. During the first nine months of 2021, the Company repaid $0.4 million on this loan.
The Company has a committed loan facility in Japan. As of October 3, 2021, $3.2 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.6 million on this facility during the first nine months of 2021.
As of October 3, 2021, the Company had $26.0 million in uncommitted short-term bank credit lines, of which $0.5 million was in use.
Note 11. Benefit Plans
The Company and its subsidiaries have pension plans covering eligible employees on a contributory or non-contributory basis. The Company also provides postretirement health care and life insurance benefits for eligible 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 22% 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 $0.7 million is included in other current liabilities and the long-term portion of the liability of approximately $23.6 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheet as of October 3, 2021.
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. 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. 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 our subsidiaries AMCOL International Corporation or American Colloid Company, which we acquired in 2014, 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 liabilities related to sales prior to the initial public offering. 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 or American Colloid prior to completion of the acquisition). 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.
Note 15. Segment and Related Information
On a regular basis, the Company reviews its segments and the approach used by the chief operating decision maker to assess performance and allocate resources. Accordingly, in the first quarter of 2021, the Company reorganized the management structure for its Energy Services and Performance Materials operating segments to support MTI's key growth initiatives, more closely align complementary technologies, processes and capabilities, and better reflect the way performance is evaluated and resources are allocated. As a result, Energy Services was combined into the Environmental Products product line within the Performance Materials operating segment. Presented below are the restated financial results, by product line, of this operating segment for each quarter of 2020 to conform to the current management structure.

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 October 3, 2021, the related condensed consolidated statements of income and comprehensive income for the three-month and nine-month periods ended October 3, 2021 and September 27, 2020, the related condensed consolidated statements of cash flows for the nine-month periods ended October 3, 2021 and September 27, 2020, the related condensed consolidated statements of changes in shareholders' equity for the three-month periods ended October 3, 2021, July 4, 2021 and April 4, 2021 and September 27, 2020, June 28, 2020 and March 29, 2020, 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, 2020, 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 19, 2021 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, 2020, 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 third quarter of 2021 were $473.2 million, an increase of 22% as compared with $388.3 million in the prior year. Included in sales for the third quarter 2021 were $20 million in sales related to our Normerica acquisition. Foreign exchange had a favorable impact on sales of approximately $6 million, or 2 percentage points as compared with prior year. Income from operations was $60.6 million and represented 12.8% of sales, as compared with $48.5 million and 12.5% of sales in the prior year. Included in income from operations for the third quarter of 2021, were $1.5 million of acquisition-related expenses and $1.1 million of restructuring and other items. Included in income from operations for the third quarter of 2020 were $1.5 million of restructuring and other items and $1.5 million of litigation expenses associated with the bankruptcy of Novinda Corp. Net income was $41.4 million, as compared to $28.3 million in the third quarter of 2020. Diluted earnings in the third quarter ended October 3, 2021 were $1.22 per share, as compared with $0.83 per share in the third quarter of 2020.
Third quarter 2021 results were strong with sales and operating income growth in each of our segments as demand in many of our end markets continue to improve. In addition, operational measures we have taken to enhance our margin profile have helped us deliver higher earnings. The Company has also made progress with our strategic growth initiatives through the commercialization of new value-added products and geographic expansion.
On July 26, 2021, the Company completed the acquisition of Normerica Inc., a leading North American supplier of premium quality cat litter. As a leader in the pet product industry, they provide premium products, both branded and private label to world-class retailers and their product portfolio consists primarily of bentonite-based cat litter products. In addition, in November, we acquired the Specialty PCC assets of a company in the Midwest U.S., helping us expand our manufacturing reach and providing us a strategic logistics footprint at a key point along the Mississippi River.
Our balance sheet continues to be strong. Cash, cash equivalents and short-term investments were $311.3 million as of October 3, 2021 and the Company had more than $500 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 has not had a material effect on our reported results for our third quarter of 2021 and we do not expect it will negatively impact our business and results of operations for our fourth quarter. However, the extent to which our operations will be impacted by the pandemic will depend largely on future developments, including the severity of future outbreaks 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 2021, 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 FLUORO-SORB® products which remediate contamination of Per-and polyflouroalkyl substances (PFAS) and Perflourooctane sulfanate (PFOS).

| ● | 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.

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

| ● | 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.

22

| ● | 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.

Liquidity and Capital Resources
Cash provided from operations during the nine months ended October 3, 2021, was approximately $163 million. Cash flows provided from operations during the nine months of 2021 were principally used to fund acquisitions and capital expenditures, repurchase shares and to pay the Company's dividend to common shareholders. The aggregate maturities of long-term debt are as follows: remainder of 2021 - $0.3 million; 2022 - $0.8 million; 2023 - $0.6 million; 2024 - $548.6 million; 2025 - $0.0 million; thereafter - $401.4 million.
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.
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 (if any) and commitments under the Revolving Facility will mature and terminate, as the case may be, on April 18, 2023. Loans under the fixed rate tranche of the Term Facility were repaid in full in June 2020. 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 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 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% 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.
32

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 Normerica acquisition, the Company incurred $100 million of short-term debt under the Revolving Facility. As of October 3, 2021, there were $$100.0 million in loans and $10.7 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 matured in the third quarter of 2020 and the other of which matures in 2022. The Company repaid $0.4 million on these loans during the nine months of 2021.
The Company has a committed loan facility in Japan. As of October 3, 2021, $3.2 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.6 million on this facility during the nine months of 2021.
As of October 3, 2021, the Company had $26.0 million in uncommitted short-term bank credit lines, of which $0.5 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 2021 should be between $80 million and $85 million, principally related to the construction of PCC plants and other opportunities that meet our strategic growth objectives.
During 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 instrument at October 3, 2021 is a liability of $5.2 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. The fair value of this instrument at October 3, 2021 is an asset of $6.9 million. 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%.
On October 21, 2020, 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 October 3, 2021, 1,016,088 shares have been repurchased under this program for $74.1 million, or an average price of approximately $72.90 per share. This program has been completed.
On October 20, 2021, 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.
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 nine months ended October 3, 2021, 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, 2020.
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.
33

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 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, 2020, 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. All recently issued ASUs 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.
Recently Adopted Accounting Standards
Simplifying the Accounting for Income Taxes
In December 2019, the FASB issued ASU 2019-12, "Simplifying the Accounting for Income Taxes", to simplify the accounting for income taxes and improve consistent application by clarifying or amending existing guidance. The Company adopted this guidance on January 1, 2021. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.
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 Company adopted this guidance on January 1, 2021. 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.
34

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 $1.3 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.
During 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 instrument at October 3, 2021 is a liability of $5.2 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. The fair value of this instrument at October 3, 2021 is an asset of $6.9 million. 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%.
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 October 3, 2021 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
PART II – OTHER INFORMATION
Item 1. Legal Proceedings
The Company and its subsidiaries are involved in the legal and environmental proceedings described in Note 14 to the condensed consolidated financial statements included elsewhere in this report, which disclosure is incorporated herein by reference. From time to time, the Company and its subsidiaries are also the subject of various routine legal actions and claims arising in the ordinary course of their businesses. The Company does not anticipate that the individual or aggregate liability arising out of litigation pending or claims known to be threatened against the Company and its subsidiaries will have a material adverse effect on the Company's results of operations, cash flows or financial condition.
