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, 2017. 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 September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.
Certain reclassifications were made to prior year amounts to conform to current year presentation as a result of the adoption of ASU 2017-07.
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, chromite 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 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.

Leases
In February 2016, the FASB issued ASU 2016-02, "Leases", which requires lessees to recognize most leases on-balance sheet, thereby increasing their reported assets and liabilities, in some cases very significantly. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company has made considerable progress in completing its assessment of the impact of this standard. The Company has performed a high level analysis of its current lease portfolio and has established a cross-functional project team to assist in the implementation of this ASU. We have assembled an inventory of our current leases, are developing processes and tools, including lease management software, to implement the new standard, and are identifying and designing changes to internal controls. Based on the current status of this assessment, the adoption of this standard is not expected to have a material impact on the Company's financial statements.
Intangibles – Goodwill and Other
In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment", which no longer requires an entity to perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, goodwill will be measured using the difference between the carrying amount and the fair value of the reporting unit. The standard is effective for the interim and annual periods beginning on or after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements. We are currently evaluating the timing of adoption of this standard.
Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
In February 2018, the FASB issued ASU 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act. The standard is effective for the interim and annual periods beginning after December 15, 2018, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Retirement Benefits
In August 2018, the FASB issued ASU 2018-14, "Compensation – Retirement Benefits – Defined Benefit Plans – General: Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of certain disclosures and adds disclosure requirements identified as relevant. The standard is effective for annual periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Fair Value Measurement
In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement," which eliminates, amends and adds disclosure requirements for fair value measurement. The standard is effective for the interim and annual periods beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Recently Adopted Accounting Standards
On January 1, 2018, the Company adopted the provisions of ASU No. 2014-09, "Revenue from Contracts with Customers". The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The standard also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. The Company has elected to use the cumulative effect transition method and there has not been a change to our previously reported financial results.

Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We measure revenue based on the consideration specified in the customer arrangement and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. Customers typically receive the benefit as goods are delivered and services are performed.
We utilized a comprehensive approach to assess the impact of the standard on our contract portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the new requirements to our revenue contracts, including evaluation of our performance obligations, principal versus agent considerations and variable consideration. We completed our contract and business process reviews and implemented changes to our controls to support recognition and disclosures under the new standard. We recognize revenue when our performance obligation is satisfied. See Note 2 to the Condensed Consolidated Financial Statements.
On January 1, 2018, the Company adopted the provisions of ASU 2017-07, "Compensation – Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost", which requires companies to present the service cost component of the net benefit cost in the same line items in which they report compensation cost. All other components of net periodic benefit cost will be presented outside operating income. The provisions have been applied retrospectively for the income statement presentation requirements. Prior to the adoption of the standard, the Company classified all net periodic benefit costs within operating costs, primarily within "Marketing and administrative expenses" on the Condensed Consolidated Statement of Income. The line item classification changes required by the standard did not impact the Company's pre-tax earnings or net income; however, "Income from operations" and "Other non-operating income (deductions), net" changed by immaterial offsetting amounts. As a result of the accounting change, the Company reclassified approximately $0.4 million and $1.3 million from marketing and administrative expenses to other deductions for the three and nine month periods ended October 1, 2017 to conform to the current year presentation.
On January 1, 2018, the Company early adopted the provisions of ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which improves and simplifies existing standard to allow companies to better reflect their risk management activities in the financial statements. The standard expands the ability to hedge nonfinancial and financial risk components, eliminates the requirement to separately measure and recognize hedge ineffectiveness and eases requirements of an entity's assessment of hedge effectiveness. The adoption of this standard did not have an impact on the Company's financial statements.
On January 1, 2018, the Company adopted the provisions of ASU 2017-01, "Business Combinations," which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The adoption of this new standard did not have an impact on the Company's financial statements.
Note 2. Revenue from Contracts with Customers
The Company's revenues are primarily derived from the sale of products. Our primary performance obligation (the sale of products) is satisfied upon shipment or delivery to our customers based on written sales terms, which is also when control is transferred. In most of the Company's PCC contracts, the price per ton is based upon the total number of tons sold to the customer during the year. Under these contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual volume that will be sold to such customer. Revenues are adjusted at the end of each year to reflect the actual volume sold. The Company also has consignment arrangements with certain customers in our Refractories segment. Revenues for these transactions are recorded when the consigned products are consumed by the customer and control is transferred to the customer.
Revenue from sales of equipment, primarily in our Refractories segment, is recorded upon completion of installation and control is transferred to the customer. Revenue from services is recorded when the services have been performed.
Revenue from long-term construction, primarily in our Energy Services segment, where our performance obligations are satisfied in phases, is recognized over time using certain output measures based on the measurement of the value transferred to the customer, including milestones achieved.

Note 3. Business Combination
On April 30, 2018, the Company completed the acquisition of Sivomatic Holding B.V. ("Sivomatic"), a leading European supplier of premium pet litter products. Sivomatic is a vertically integrated manufacturer, with production facilities in the Netherlands, Austria and Turkey. With a leading position in premier clumping products, Sivomatic's product portfolio spans the range of pet litter derived from bentonite, sourced predominantly from wholly-owned mines in Turkey. The results of Sivomatic are included in our Performance Materials segment. Sivomatic has approximately 115 employees and generated revenue of €73 million in 2017. The acquisition was financed through a combination of cash on hand and borrowings under the Company's credit facilities. The fair value of the total consideration transferred, net of cash acquired, was $122.5 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 September 30, 2018, the purchase price allocation remains preliminary as the Company completes its assessment of property, mineral rights, certain reserves including environmental, legal and tax matters, obligations, intangible assets and deferred taxes, as well as complete our review of Sivomatic's existing accounting policies.
The following table summarizes the Company's preliminary purchase price allocation for the Sivomatic acquisition:

(millions of dollars) |  | Preliminary Allocation |
Accounts receivable |  | $ | 24.4 |
Inventories |  |  | 15.6 |
Other current assets |  |  | 0.6 |
Mineral rights |  |  | 35.0 |

Non-current deferred tax liability |  |  | 16.2 |
Other non-current liabilities |  |  | 0.1 |
Total liabilities assumed |  |  | 41.9 |
Net assets acquired |  | $ | 122.5 |

The Company used the income, market, or cost approach (or a combination thereof) for the preliminary 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 Sivomatic businesses and will be allocated to the Performance Materials segment. The allocation is expected to be completed during the first quarter of 2019. Goodwill recognized as a result of this acquisition is not deductible for tax purposes.
In connection with the acquisition, the Company recorded an additional deferred tax liability of $15.0 million with a corresponding increase to goodwill. The increase in deferred tax liability represents the tax effect of the difference between the estimated assigned fair value of the tangible and intangible assets and the tax basis of such assets.
Mineral rights were valued using discounted cash flow method, a Level 3 fair value input. Plant, property and equipment were valued using the cost method adjusted for age and deterioration, also a Level 3 fair value input.
Intangible assets acquired mainly include tradenames and customer relationships. Tradenames are a Level 3 fair value input, with an estimated useful life of 25-30 years. Customer relationships are a Level 3 fair value input, with an estimated useful life of 25-30 years.
The Company incurred $0.3 million and $1.7 million of acquisition-related costs during the three-month and nine-month periods ended September 30, 2018, which are reflected within the acquisition-related transaction and integration costs line of the Condensed Consolidated Statements of Income. We did not present pro forma and other financial information for the Sivomatic acquisition, as this is not considered to be a material business combination.

Options to purchase 352,625 shares and 184,569 shares of common stock for the three-month and nine-month periods ended September 30, 2018 and October 1, 2017, 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
At September 30, 2018, the Company had $3.9 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 December 2018.
The following table is a reconciliation of our restructuring liability balance as of September 30, 2018 :

Restructuring liability, September 30, 2018 |  | $ | 3.9 |

Note 6. Income Taxes
During the fourth quarter of 2017, the U.S. Tax Cuts and Jobs Act ("U.S. Tax Reform"), was enacted in the United States. Amongst its many provisions, U.S. Tax Reform reduced the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018, and created a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries. As a result of the enactment of U.S. Tax Reform, we recognized a provisional net tax benefit of $47.3 million in the fourth quarter of 2017. We are applying the guidance in Staff Account Bulletin No. 118 ("SAB 118"), Income Tax Accounting Implications of the Tax Cuts and Jobs Act, issued by the Securities and Exchange Commission, when accounting for the enactment-date effects of U.S. Tax Reform. As permitted by SAB No. 118, some elements of the tax expense recorded in the fourth quarter of 2017 due to the enactment of U.S. Tax Reform were based on reasonable estimates and considered provisional. The Company is continuing to collect and analyze detailed information about the earnings and profits of its non-U.S. subsidiaries, the related taxes paid, the amounts which could be repatriated, the foreign taxes which may be incurred on repatriation and the associated impact of these items under U.S. Tax Reform. The Company may record adjustments to refine those estimates during the measurement period, as additional analysis is completed. See Note 5 to our consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 for further information on this provisional net tax benefit. No adjustments to the provisional net tax benefit were recorded during the nine months ended September 30, 2018.
U.S. Tax Reform also created a new requirement that certain income earned by foreign subsidiaries, known as global intangible low-tax income ("GILTI"), must be included in the gross income of their U.S. shareholder. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or recognizing such taxes as a current-period expense when incurred. Given the complexity of the GILTI provisions, we are still evaluating the effects of the GILTI provisions and have not yet determined our accounting policy. At September 30, 2018, because we are still evaluating the GILTI provisions and our analysis of future taxable income that is subject to GILTI, we have included GILTI related to current-year operations only in our estimated annual effective tax rate and have not provided additional GILTI on deferred items.

(Unaudited)
The recorded impact of U.S. Tax Reform is provisional and the final amount may differ, possibly materially, due to, among other things, changes in estimates, interpretations and assumptions we made, changes in IRS interpretations, the issuances of new guidance, legislative actions, or related interpretations in response to U.S. Tax Reform and future actions by states within the United States that have not conformed their tax laws to U.S. Tax Reform.
As of September 30, 2018, the Company had approximately $15.7 million of total unrecognized income tax benefits. Included in this amount were a total of $12.1 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 $0.2 million and $0.7 million during the three and nine-months ended September 30, 2018 and had an accrued balance of $2.3 million of interest and penalties as of September 30, 2018.
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.
Provision for taxes was $9.7 million and $29.3 million during the three and nine-months ended September 30, 2018, respectively. The effective tax rate was 18.8% as compared to 22.6% in the prior year. The lower effective tax rate was primarily due to U.S. Tax Reform.
Note 7. Inventories
The following is a summary of inventories by major category:

(millions of dollars) |  | Sep. 30, 2018 |  |  | Dec. 31, 2017 |

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 $808.1 million, and $779.3 million as of September 30, 2018 and December 31, 2017, respectively. The net change in goodwill since December 31, 2017 was primarily attributable to the acquisition of Sivomatic (see Note 3 to the Condensed Consolidated Financial Statements) and to the impact of foreign exchange.

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 28 years. Estimated amortization expense is $2.2 million for the remainder of 2018, $34.8 million for 2019–2022 and $173.3 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.
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.
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.
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.
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 $0.2 million at September 30, 2018 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 $157 million at September 30, 2018. The fair value of this swap is an asset of $3.7 million at September 30, 2018 and is recorded in other non-current assets on the Condensed Consolidated Balance Sheet. These interest rate swaps are designated as cash flow hedges. The gains and losses associated with these interest rate swaps are recorded in accumulated other comprehensive income (loss).
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 a liability of $0.5 million at September 30, 2018 and is recorded in other non-current liabilities on the Condensed Consolidated Balance Sheet. Changes in the fair value of this 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 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 (the "Revolving Facility" and, together with the Term Facility, the "Facilities").
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 the Revolving Facility. As amended, the Revolving Facility has been increased to $300 million in aggregate commitments. Following the amendments, the loans outstanding under the floating rate tranche of the Term Facility will mature on February 14, 2024, the loans outstanding under the fixed rate tranche of the Term Facility will 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 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 $15 million of letters of credit), to maintain a maximum net leverage ratio (as defined in the credit agreement) of, initially, 5.25 to 1.00 for the four fiscal quarters preceding such day. Such maximum net leverage ratio requirement is subject to decrease during the duration of the facility to a minimum level (when applicable) of 3.50 to 1.00.
As of September 30, 2018, there were $103 million in outstanding loans and $8.9 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.
The Company has committed loan facilities for the funding of new manufacturing facilities in China. In addition, the Company has a committed loan facility in Japan. As of September 30, 2018, on a combined basis, $6.1 million was outstanding under these loan facilities. Principal will be repaid in accordance with the payment schedules ending in 2021. The Company repaid $2.7 million on these loans during the first nine months of 2018.
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 second and third quarters of 2018, the Company repaid $4.8 million on these loans.
As of September 30, 2018, the Company had $36.6 million in uncommitted short-term bank credit lines, of which approximately $5.3 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 25% of our total benefit obligation.

The Company expects to contribute approximately $24.0 million to its pension plans and $0.5 million to its other postretirement benefit plans in 2018. As of September 30, 2018, $18.6 million has been contributed to the pension plans and approximately $0.1 million has been contributed to the other postretirement benefit plans.
Included in net periodic benefit cost for the three-month and nine-month periods ended September 30, 2018 are non-cash pension settlement costs of $3.6 million associated with our pension plans in the U.S.
On January 1, 2018, the Company retrospectively adopted the provisions of ASU 2017-07, "Compensation – Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". Under the new standard, the Company classifies all net periodic benefit costs within the "Other non-operating income (deductions), net" line item on the consolidated statement of income. The line item classification changes required by the standard did not impact the Company's pre-tax earnings or net income; however, "Income from operations" and "Other non-operating income (deductions), net" changed by immaterial offsetting amounts.

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 following is a reconciliation of asset retirement obligations as of September 30, 2018:

(millions of dollars) |  |  |
Asset retirement liability, December 31, 2017 |  | $ | 22.1 |
Accretion expense |  |  | 0.8 |
Other |  |  | 0.4 |
Payments |  |  | (1.0 | )
Foreign currency translation |  |  | (0.5 | )
Asset retirement liability, September 30, 2018 |  | $ | 21.8 |

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 $21.4 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheet as of September 30, 2018.
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. The Company currently has three pending silica cases and 29 pending asbestos cases. To date, 1,493 silica cases and 54 asbestos cases have been dismissed, not including any lawsuits against AMCOL or American Colloid Company dismissed prior to our acquisition of AMCOL. Four new asbestos cases were filed during the third quarter of 2018. No asbestos or silica cases were dismissed during the period. 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, 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 29 pending asbestos cases, 24 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 two of the three remaining non-AMCOL cases, the plaintiffs have not alleged dates of exposure, and in the third remaining non-AMCOL case, exposure is alleged to have been after the Company's initial public offering in 1992. The remaining 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.

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 September 30, 2018.
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 September 30, 2018.
The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses.

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 September 30, 2018, the related condensed consolidated statements of income and comprehensive income for the three-month and nine-month periods ended September 30, 2018 and October 1, 2017, the related condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2018 and October 1, 2017, 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, 2017, and the related consolidated statements of income and comprehensive income, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated February 16, 2018, 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, 2017, 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
Consolidated sales for the third quarter of 2018 were $464.1 million as compared with $424.4 million in the prior year. Income from operations was $68.2 million and represented 14.7% of sales as compared with $67.2 million and 15.8% of sales in the prior year. Net income was $41.9 million as compared to $41.7 million in the third quarter of 2017.
Diluted earnings in the third quarter ended September 30, 2018 were $1.18 per share compared with $1.17 per share in 2017. Included in pre-tax income and earnings per share were $0.3 million of acquisition-related transaction and integration costs and $0.3 million of restructuring charges.

Our balance sheet continues to be strong. Cash, cash equivalents and short-term investments were $211.2 million as of September 30, 2018. We repaid $30 million of our debt in the third quarter. Our intention continues to be to maintain a balanced approach to capital deployment, by using excess cash flow for investments in growth, debt reduction and selective share repurchases.
Outlook
Looking forward, we remain cautious about the state of the global economy and the impact it will have on our product lines.
The Company will continue to focus on innovation and new product development and other opportunities for sales growth in 2018 from its existing businesses, as follows:

Environmental Products sales rose 24% due to several large projects. These sales increases were partially offset by 5% lower sales in Building Materials, primarily due to the difference in the magnitude of waterproofing projects compared to the prior year, and a 15% reduction in Basic Minerals sales due to the planned exit of bulk chromite operations in South Africa.
Income from operations was $87.6 million and 14.1% of sales as compared to $91.6 million and 17.0% of sales in the prior year. The decrease in operating income was due to higher raw material, logistics and energy costs as well as declines in bulk chromite sales and related profit.

Net sales in the Energy Services segment increased 4% to $58.0 million from $55.6 million in the prior year, primarily driven by higher filtration activity in the North Sea and the Gulf of Mexico.
Income from operations during the nine months ended September 30, 2018 was $3.3 million and represented 5.7% of sales. Income from operations was $4.8 million and 8.6% of sales during the nine months ended October 1, 2017.
Liquidity and Capital Resources
Cash provided from continuing operations during the nine months ended September 30, 2018, was approximately $133 million. Cash flows provided from operations during the first nine months of 2018 were principally used to repay debt, fund the Company's pension plans, fund 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 2018 - $2.3 million; 2019 - $3.3 million; 2020 - $2.2 million; 2021 - $303.7 million; 2022 - $0.0 million; thereafter - $658.2 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 (the "Revolving Facility" and, together with the Term Facility, the "Facilities"). The net proceeds of the Term Facility, together with the Company's cash on hand, were used as cash consideration for the acquisition of AMCOL and to refinance certain existing indebtedness of the Company and AMCOL and to pay fees and expenses in connection with the foregoing. Loans under the Revolving Facility will be used for working capital and other general corporate purposes of the Company and its subsidiaries.
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 the Revolving Facility. As amended, the Revolving Facility has been increased to $300 million in aggregate commitments. Following the amendments, the loans outstanding under the floating rate tranche of the Term Facility will mature on February 14, 2024, the loans outstanding under the fixed rate tranche of the Term Facility will 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 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.
31

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 $15 million of letters of credit), to maintain a maximum net leverage ratio (as defined in the credit agreement) of, initially, 5.25 to 1.00 for the four fiscal quarter periods preceding such day. Such maximum net leverage ratio requirement is subject to decrease during the duration of the facility to a minimum level (when applicable) of 3.50 to 1.00. As of September 30, 2018, there were $103 million in outstanding loans and $8.9 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.
The Company has committed loan facilities for the funding of new manufacturing facilities in China. In addition, the Company has a committed loan facility in Japan. As of September 30, 2018, on a combined basis, $6.1 million was outstanding under these loan facilities. Principal will be repaid in accordance with the payment schedules ending in 2021. The Company repaid $2.7 million on these loans during the first nine months of 2018.
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 second and third quarters of 2018, the Company repaid $4.8 million on these loans.
As of September 30, 2018, the Company had $36.6 million in uncommitted short-term bank credit lines, of which approximately $5.3 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 2018 should be between $70.0 million and $80.0 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 September 30, 2018 was an asset of $3.7 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 September 30, 2018 was a liability of $0.3 million.
On September 21, 2017, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $150 million of the Company's shares over a two-year period commencing October 1, 2017. As of September 30, 2018, 230,650 shares were repurchased under this program for $16.4 million, or an average price of approximately $70.91 per share.
32

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 September 30, 2018, 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, 2017.
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.
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 affecting the expectations and forecasts are set forth under "Item 1A — Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, 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.
Leases
In February 2016, the FASB issued ASU 2016-02, "Leases", which requires lessees to recognize most leases on-balance sheet, thereby increasing their reported assets and liabilities, in some cases very significantly. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company has made considerable progress in completing its assessment of the impact of this standard. The Company has performed a high level analysis of its current lease portfolio and has established a cross-functional project team to assist in the implementation of this ASU. We have assembled an inventory of our current leases, are developing processes and tools, including lease management software, to implement the new standard, and are identifying and designing changes to internal controls. Based on the current status of this assessment, the adoption of this standard is not expected to have a material impact on the Company's financial statements.
Intangibles – Goodwill and Other
In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment", which no longer requires an entity to perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, goodwill will be measured using the difference between the carrying amount and the fair value of the reporting unit. The standard is effective for the interim and annual periods beginning on or after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements. We are currently evaluating the timing of adoption of this standard.
33

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
In February 2018, the FASB issued ASU 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The standard is effective for the interim and annual periods beginning after December 15, 2018, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Retirement Benefits
In August 2018, the FASB issued ASU 2018-14, "Compensation – Retirement Benefits – Defined Benefit Plans – General: Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which removes disclosures that no longer are considered cost beneficial, clarifies the specific requirements of certain disclosures and adds disclosure requirements identified as relevant. The standard is effective for annual periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's financial statements.
Fair Value Measurement
In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement," which eliminates, amends and adds disclosure requirements for fair value measurement. The standard is effective for the interim and annual periods beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the timing of adoption of this standard. The adoption of this standard is not expected to have a material impact on the Company's 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.
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 would result in $3.5 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 September 30, 2018 was an asset of $3.7 million.
34

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 September 30, 2018 was a liability of $0.3 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 September 30, 2018 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 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. The Company currently has three pending silica cases and 29 pending asbestos cases. To date, 1,493 silica cases and 54 asbestos cases have been dismissed, not including any lawsuits against AMCOL or American Colloid Company dismissed prior to our acquisition of AMCOL. Four new asbestos cases were filed during the third quarter of 2018. No asbestos or silica cases were dismissed during the quarter. 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, 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. Of the 29 pending asbestos cases, 24 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 two of the three remaining non-AMCOL cases, the plaintiffs have not alleged dates of exposure, and in the fourth remaining non-AMCOL case, exposure is alleged to have been after the Company's initial public offering in 1992. The remaining 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.
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 September 30, 2018.
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 September 30, 2018.
