Summary of Significant Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Note 1. Summary of Significant Accounting Policies Business The Company is a resource- and technology-based company that develops, produces and markets on a worldwide basis a broad range of specialty mineral, mineral-based and synthetic mineral products and supporting systems and services. Basis of Presentation The accompanying consolidated financial statements include the accounts of Minerals Technologies Inc. (the "Company"), its wholly and majority-owned subsidiaries, as well as variable interest entities for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. 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, pension plan assumptions, income tax, and litigation and environmental liabilities. Actual results could differ from those estimates. Cash Equivalents and Short-term Investments The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Short-term investments consist of financial instruments, mainly bank deposits, with original maturities beyond three months, but less than twelve months. Short-term investments amounted to $2.7 were no unrealized holding gains and losses on the short-term bank investments held at . Trade Accounts Receivable Trade accounts receivables are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific allowances for bankrupt customers. The Company also analyzes the collection history and financial condition of its other customers, considering current industry conditions and determines whether an allowance needs to be established. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days based on payment terms are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers. Inventories Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. Additionally, items such as idle facility expense, excessive spoilage, freight handling costs, and re-handling costs are recognized as current period charges. The allocation of fixed production overheads to the costs of conversion are based upon the normal capacity of the production facility. Fixed overhead costs associated with idle capacity are expensed as incurred. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. The straight-line method of depreciation is used for substantially all of the assets for financial reporting purposes, except for mining related equipment which uses units-of-production method. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets. The estimated useful lives of our PCC production facilities and machinery and equipment pertaining to our natural stone mining and processing plants and our chemical plants are 15 years. Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of PCC are predominantly pursuant to long-term evergreen contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge or accelerated depreciation at such facility. Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes, based upon proven and probable reserves, and on a percentage depletion basis for tax purposes. Stripping Costs Incurred During Production Stripping costs are those costs incurred for the removal of waste materials for the purpose of accessing ore body that will be produced commercially. Stripping costs incurred during the production phase of a mine are variable costs that are included in the costs of inventory produced during the period that the stripping costs are incurred. Accounting for the Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, the Company estimates the undiscounted future cash flows (excluding interest), resulting from the use of the asset and its ultimate disposition. If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset, determined principally using discounted cash flows. Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. Goodwill is not amortized, but instead assessed for impairment. Intangible assets with estimable useful lives are amortized on a straight-line basis over their respective estimated lives to the estimated residual values, and reviewed for impairment. The Company performs a qualitative assessment for each of its reporting units to determine if the two step process for impairment testing is required. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company would then evaluate the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the fair value for the reporting unit is compared to its book value including goodwill. In the case that the fair value of the reporting unit is less than book value, a second step is performed which compares the fair value of the reporting unit's goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values of the reporting unit and the net fair values of the identifiable assets and liabilities of such reporting unit. If the fair value of the goodwill is less than the book value, the difference is recognized as impairment. Investment in joint ventures The Company uses the equity method of accounting to incorporate the results of its investments in companies in which it has significant influence, but does not control; and cost method of accounting in companies in which it cannot exercise significant control. The Company records the equity in earnings of its investments in joint ventures on a one month lag. At December 31, 2017, the book value of Company’s equity method investment was $16.1 million. The Company had no cost method investments at December 31, 2017. Accounting for Asset Retirement Obligations The Company provides for obligations associated with the retirement of long-lived assets and the associated asset retirement costs. The fair value of a 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 associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company also provides for legal obligations to perform asset retirement activities where timing or methods of settlement are conditional on future events. The Company also records liabilities related to land reclamation as a part of the asset retirement obligations. The Company mines land for various minerals using a surface-mining process that requires the removal of overburden. In many instances, the Company is obligated to restore the land upon completion of the mining activity. As the overburden is removed, the Company recognizes this liability for land reclamation based on the estimated fair value of the obligation. The obligation is adjusted to reflect the passage of time and changes in estimated future cash outflows. Fair Value of Financial Instruments The recorded amounts of cash and cash equivalents, receivables, short-term borrowings, accounts payable, accrued interest, and variable-rate long-term debt approximate fair value because of the short maturity of those instruments or the variable nature of underlying interest rates. Short-term investments are recorded at cost, which approximates fair market value. Derivative Financial Instruments The Company records derivative financial instruments which are used to hedge certain foreign exchange risk at fair value on the balance sheet. See Note 9 for a full description of the Company's hedging activities and related accounting policies. Revenue Recognition Revenue from sale of products is recognized when title passes to the customer, the customer assumes the risks and rewards of ownership, and collectability is reasonably assured; generally, this occurs when the goods are shipped to the customer. 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 those 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. Revenue from sales of equipment is recorded upon completion of installation and receipt of customer acceptance. Revenue from services is recorded when the services have been performed and collectability is reasonably assured. Revenue from long-term construction contracts is recorded using the percentage-of-completion method. Progress is generally based upon costs incurred to date as compared to the total estimated costs to complete the work under the contract or the amount of product installed in relation to the total amount expected to be installed. All known or anticipated losses on contracts are provided when they become evident. Cost adjustments that are in the process of being negotiated with customers for extra work or changes in scope of work are included in revenue when collection is reasonably assured. Foreign Currency The assets and liabilities of the Company's international subsidiaries are translated into U.S. dollars using exchange rates at the respective balance sheet date. The resulting translation adjustments are recorded in accumulated other comprehensive income (loss) in shareholders' equity. Income statement items are generally translated at monthly average exchange rates prevailing during the period. International subsidiaries operating in highly inflationary economies translate non-monetary assets at historical rates, while net monetary assets are translated at current rates, with the resulting translation adjustments included in net income. At December 31, 2017, the Company had no international subsidiaries operating in highly inflationary economies. Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company operates in multiple taxing jurisdictions, both within the U.S. 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 regularly assesses its tax position for such transactions and includes reserves for those differences in position. The reserves are utilized or reversed once the statute of limitations has expired or the matter is otherwise resolved. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations. The Company's accounting policy is to recognize interest and penalties as part of its provision for income taxes. See Note 5 for additional detail on our uncertain tax positions. The accompanying financial statements do not include a provision for foreign withholding taxes on international subsidiaries' unremitted earnings, which are expected to be permanently reinvested overseas. Research and Development Research and development costs are expensed as incurred. Accounting for Stock-Based Compensation The Company recognizes compensation expense for share-based awards based upon the grant date fair value over the vesting period. Pension and Post-retirement Benefits The Company has defined benefit pension plans covering the majority of its employees. The benefits are generally based on years of service and an employee's modified career earnings. The Company also provides post-retirement healthcare benefits for the majority of its retirees and employees in the United States. The Company measures the costs of its obligation based on its best estimate. The net periodic costs are recognized as employees render the services necessary to earn the post-retirement benefits. Environmental Expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and which do not contribute to current or future revenue generation are expensed. Liabilities are recorded when it is probable the Company will be obligated to pay amounts for environmental site evaluation, remediation or related costs, and such amounts can be reasonably estimated. Earnings Per Share Basic earnings per share have been computed based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share have been computed based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding. Subsequent Events The Company has evaluated for subsequent events through the date of issuance of its financial statements. Recently Issued Accounting Standards Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of operations. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” which will supersede nearly all existing revenue recognition guidance under U.S. GAAP. 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 guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2017. The guidance permits the use of either a retrospective or cumulative effect transition method. The Company has completed its evaluation of the provisions of this standard and we have concluded that our adoption of ASU No. 2014-09 will not materially change the amount or timing of revenues recognized by us, nor will it materially affect our financial position. We have adopted this new standard effective January 1, 2018. The Company has elected to use the cumulative effect transition method and there will not be a change to our previously reported financial results. 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 is currently evaluating the impact of this ASU on the Company’s consolidated financial statements and related disclosures. Based on the current status of this assessment, the adoption of this guidance 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2019, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements. Compensation – Retirement Benefits In March 2017, the FASB issued 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2017. We adopted this new standard effective January 1, 2018. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements. Derivatives and Hedging In August 2017, the FASB issued accounting guidance to improve and simplify existing guidance to allow companies to better reflect their risk management activities in the financial statements. The guidance 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 guidance is not expected to have a material impact on the Company’s financial statements. Adoption of ASU 2016-09, Stock Compensation- Improvements to Employee Share-Based Payment Accounting On January 1, 2017, the Company adopted the provisions of ASU 2016-09, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting”, an amendment to account standards codification (“ASC”) 718, which simplifies several aspects of accounting for share-based payments, including accounting for income taxes, forfeitures, statutory withhold rates as well as presentation on the statement of cash flows. The Company has elected to adopt the standard on a prospective basis. As a result of this adoption, the Company recognizes excess tax benefits in the current account period. The cash flow benefit of the excess tax benefit is included as an operating activity in the Consolidated Statement of Cash Flows for the period ended December 31, 2017. Additionally, taxes paid for shares withheld for tax-withholding purposes are reported as financing activities in the Condensed Consolidated Statements of Cash Flows. Previously, this activity was included in operating activities. Prior year Condensed Consolidated Statement of Cash Flows has not been restated. In accordance with the standard, the Company will continue to account for forfeitures using an estimated forfeiture rate. |

Restructuring and Other Items, net | Note 2. Restructuring and Other Items, net In 2015, the Company recognized impairment charges for certain underutilized coiled tubing equipment within the Energy Services segment which have been abandoned by the Company. In 2016, the Company recognized additional restructuring charges for lease termination costs, inventory write-offs and impairment of assets relating to its exit from the Nitrogen and Pipeline product lines and restructuring of other onshore services within the Energy Services segment as a result of the significant reduction in oil prices and overcapacity in the onshore oil service market. The Company expects to realize further annualized savings from this restructuring program of $11.5 million (unaudited). In addition, the Company recognized a $2.9 million gain on previously impaired assets in the Refractories and Energy Services Segments. In 2017, the Company recognized $15.0 million in restructuring and non-cash impairment charges from the closure of paper mills in North America, as well as the alignment of corporate and Paper PCC staffing levels into higher growth regions. The restructuring is expected to result in approximately $6 million (unaudited) in savings on an annualized basis.

Stock-Based Compensation [Abstract] | |
Stock-Based Compensation | Note 3. Stock-Based Compensation At the Company’s 2015 Annual Meeting of Stockholders, the Company’s stockholders ratified the adoption of the Company’s 2015 Stock Award and Incentive Plan (the “2015 Plan”), which provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards. The 2015 Plan is substantially similar to the Company’s 2001 Stock Award and Incentive Plan (as amended and restated as of March 18, 2009, the “2001 Plan” and collectively with the 2015 Plan, the “Plans”). The Company established the 2015 Plan to increase the total number of shares of common stock reserved and available for issuance by 880,000 shares from the number of shares remaining under the 2001 Plan. With the ratification of the 2015 Plan by the Company’s stockholders, the 2001 Plan was discontinued as to new grants (however, all awards previously granted under the 2001 Plan remained unchanged). The Plans are administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plans generally have a ten year term. The exercise price for stock options are at prices at or above the fair market value of the common stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years. Stock-based compensation expense is recognized in the consolidated financial statements for stock options based on the grant date fair value. Net income for years ended 2017, 2016 and 2015 include $4.1 million, $ million was $1.1 million, $ Stock Options The fair value of options granted is estimated on the date of grant using the Black-Scholes valuation model. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations. The forfeiture rate assumption used for the periods ended December 31, 2017, 2016 and 2015 was 8.71%, 7.38% and 7. The weighted average grant date fair value for stock options granted during the years ended December 31, 2017, 2016 and 2015 was $30.28, $ $ and $ was $11.7 million, $ million The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions for the years ended December 31, 2017, 2016 and 2015: 2017 2016 2015 Expected life (in years) 6.4 6.5 6.4 Interest rate 2.04 % 1.72 % 1.52 % Volatility 36.61 % 36.75 % 36.86 % Expected dividend yield 0.26 % 0.54 % 0.33 % The expected term of the options represents the estimated period of time until exercise and is based on historical experience of similar awards, based upon contractual terms, vesting schedules, and expectations of future employee behavior. The expected stock-price volatility is based upon the historical and implied volatility of the Company's stock. The interest rate is based upon the implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend yield is based upon historical dividends paid by the Company. The following table summarizes stock option activity for the year ended December 31, 2017: Awards Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (Millions) Awards outstanding at December 31, 2016 1,198,725 $ 41.66 Granted 187,533 77.99 Exercised (353,636 ) 41.56 Canceled (35,783 ) 50.47 Awards outstanding at December 31, 2017 996,839 $ 48.21 6.32 $ 22.2 Awards exercisable at December 31, 2017 596,446 $ 41.01 4.94 $ 16.6 The aggregate intrinsic value above is calculated before applicable income taxes, based on the Company's closing stock price of as of the last business day of the period ended had all options been exercised on that date. The weighted average intrinsic value of the options exercised during 2017, was $32.95, $ and $32.07 per share, respectively. As of , total unrecognized stock-based compensation expense related to non-vested stock options was approximately $ million, which is expected to be recognized over a weighted average period of approximately three years. The Company issues new shares of common stock upon the exercise of stock options Non-vested stock option activity for the year ended is as follows: Awards Weighted Average Grant date Fair Value Per Share Nonvested awards outstanding at December 31, 2016 431,412 $ 45.61 Granted 187,533 77.99 Vested (183,679 ) 48.78 Canceled (34,873 ) 50.08 Nonvested awards outstanding at December 31, 2017 400,393 $ 58.94 Restricted Stock The Company has granted key employees rights to receive shares of the Company's common stock pursuant to the Plan. The rights will be deferred for a specified number of years of service, subject to restrictions on transfer and other conditions. Compensation expense for these shares is recognized over the vesting period . The Company granted 69,539 shares, 155,165 shares and 216,502 shares for the periods ended , , respectively. The fair value was determined based on the market value of unrestricted shares. As of , there was unrecognized stock-based compensation related to restricted stock of $5.1 million, which will be recognized over approximately the next three years. The compensation expense amortized with respect to all units was approximately $5.9 million, $5.8 million and $8.8 million for the periods ended , , respectively. In addition, the Company recorded reversals of $2.4 million, $3.8 million and $1.6 million for periods ended , , respectively, related to restricted stock forfeitures. Such costs and reversals are included in marketing and administrative expenses.

Income Taxes [Abstract] | |
Income Taxes | Note 5. Income Taxes The U.S. Tax Cuts and Jobs Act (“U.S. Tax Reform”), enacted in December 2017, significantly changes U.S. corporate income tax laws by, among other things, reducing the U.S. corporate income tax rate to 21% starting in 2018 and creating a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries. Under U.S. GAAP (specifically, ASC Topic 740), the effects of changes in tax rates and laws on deferred tax balances are recognized in the period in which the new legislation is enacted. In response to U.S. Tax Reform, the Staff of the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB No. 118”) to provide guidance to registrants in applying ASC Topic 740 in connection with U.S. Tax Reform. SAB No. 118 provides that in the period of enactment, the income tax effects of U.S. Tax Reform may be reported as a provisional amount based on a reasonable estimate (to the extent a reasonable estimate can be determined), which would be subject to adjustment during a “measurement period.” The measurement period begins in the reporting period of the U.S. Tax Reform enactment date and ends when a registrant has obtained, prepared and analyzed the information that was needed in order to complete the accounting requirements under ASC Topic 740. SAB No. 118 also describes supplemental disclosure that should accompany the provisional amounts. U.S. Tax Reform represents the first significant change in U.S. tax law in over 30 years. 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 are 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. As a result, we have recorded a net tax benefit of $47.3 million during the fourth quarter of 2017. This amount, which is reflected within the provision for income taxes in the Consolidated Statement of Income, includes the estimated impact of the one-time mandatory tax on previously deferred earnings of non-U.S. subsidiaries offset in part by the benefit from revaluation of net deferred tax liabilities based on the new lower corporate income tax rate. The impact of the U.S. Tax Reform may differ from this estimate, possibly materially, due to, among other things, changes in interpretations and assumptions made, additional guidance that may be issued and actions taken by the Company as a result of the U.S. Tax Reform. Income from operations before provision for taxes by domestic and foreign source is as follows: 2017 2016 2015 (millions of dollars) Income from continuing operations before income taxes and income from affiliates and joint ventures: Domestic $ 96.7 $ 72.9 $ 32.6 Foreign 94.2 97.4 100.0 $ 190.9 $ 170.3 $ 132.6 The provision (benefit) for taxes on income consists of the following: 2017 2016 2015 (millions of dollars) Domestic Taxes currently payable Federal $ 46.0 $ 18.7 $ 1.4 State and local 2.4 4.4 1.2 Deferred income taxes (78.1 ) (8.8 ) (3.2 ) Domestic tax provision (benefit) (29.7 ) 14.3 (0.6 ) Foreign Taxes currently payable 21.1 23.2 22.7 Deferred income taxes 2.0 (2.2 ) 0.7 Foreign tax provision 23.1 21.0 23.4 Total tax provision (benefit) $ (6.6 ) $ 35.3 $ 22.8 The provision (benefit) for taxes on income shown in the previous table is classified based on the location of the taxing authority, regardless of the location in which the taxable income is generated. The major elements contributing to the difference between the U.S. federal statutory tax rate and the consolidated effective tax rate are as follows: 2017 2016 2015 U.S. statutory rate 35.0 % 35.0 % 35.0 % Depletion (6.7 )% (6.6 )% (8.4 )% Difference between tax provided on foreign earnings and the U.S. statutory rate (3.8 )% (6.4 )% (8.3 )% State and local taxes, net of federal tax benefit 1.1 % 1.1 % 0.3 % Tax credits and foreign dividends 0.3 % 0.6 % (0.5 )% Change in valuation allowance (1.9 )% (1.1 )% (0.9 )% Impact of uncertain tax positions 0.4 % 0.4 % (0.1 )% Impact of officer's non-deductible compensation 0.8 % 0.1 % 2.9 % Manufacturing deduction (1.6 )% (2.0 )% (2.0 )% Impact of US Tax Reform (24.8 )% 0.0 % 0.0 % Other (2.3 )% (0.4 )% (0.8 )% Consolidated effective tax rate (3.5 )% 20.7 % 17.2 % The Company believes that its accrued liabilities are sufficient to cover its U.S. and foreign tax contingencies. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below: 2017 2016 (millions of dollars) Deferred tax assets attributable to: Accrued liabilities $ 28.6 $ 49.7 Net operating loss carry forwards 33.2 34.6 Pension and post-retirement benefits costs 40.4 55.4 Other 22.0 35.0 Valuation allowance (21.4 ) (24.8 ) Total deferred tax assets 102.8 149.9 Deferred tax liabilities attributable to: Plant and equipment, principally due to differences in depreciation 161.6 251.3 Intangible assets 63.4 96.3 Other 11.6 14.0 Total deferred tax liabilities 236.6 361.6 Net deferred tax asset (liability) $ (133.8 ) $ (211.7 ) Net deferred tax assets and net deferred tax liabilities are as follows: 2017 2016 (millions of dollars) Net deferred tax asset, long-term $ 25.6 $ 27.1 Net deferred tax liability, long-term 159.4 238.8 Net deferred tax asset (liability), long-term $ (133.8 ) $ (211.7 ) The Company has $33.2 million of deferred tax assets arising from tax loss carry forwards which will be realized through future operations. Carry forwards of approximately $15.5 million expire over the next 20 years, and $17.7 million can be utilized over an indefinite period. On December 31, 2017, the Company had $14.7 million of total unrecognized tax benefits. Included in this amount were a total of $11.9 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, we do not expect the change to have a significant impact on the results of operations or the financial position of the Company. The following table summarizes the activity related to our unrecognized tax benefits: 2017 2016 (millions of dollars) Balance at beginning of the year $ 13.7 $ 4.0 Increases related to current year tax positions 1.2 8.8 Increases related to new judgements 1.2 0.9 Decreases related to audit settlements and statue expirations (1.4 ) - Balance at the end of the year $ 14.7 $ 13.7 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 recorded a $0.4 million benefit in interest and penalties during 2017 and had a total accrued balance on December 31, 2017 of $1.7 million. 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 U.S. federal, state, local, and European income tax examinations by tax authorities for years prior to 2010. Net cash paid for income taxes were $47.7 million, $30.6 The Company had approximately $531.2 million of foreign subsidiaries' undistributed earnings as of permanently reinvest these earnings overseas for the foreseeable future and while U.S. federal tax expense as been recognized as a result of U.S. Tax Reform, no deferred tax liabilities with respect to foreign withholding taxes or state taxes have been recognized. |

Goodwill and Other Intangible Assets | 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 $779.3 million and $778.7 million as of December 31, 2017 and December 31, 2016, respectively. The net change in goodwill since December 31, 2016 was attributable to the effects of foreign exchange.

Derivative Financial Instruments and Hedging Activities [Abstract] | |
Derivative Financial Instruments and Hedging Activities | Note 9. Derivative Financial Instruments and Hedging Activities 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. 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. During the second quarter of 2016, the Company entered into a floating to fixed interest rate swap for an initial aggregate notional amount of $300 million. The notional amount at December 31, 2017 was $200 million. This interest rate swap is designated as a cash flow hedge. The gains and losses associated with this interest rate swap are recorded in accumulated other comprehensive income (loss). The fair value of this swap was an asset of $2.9 million at December 31, 2017 and is recorded in other assets and deferred charges on the Consolidated Balance Sheet. In addition, the Company uses foreign exchange forward contracts to protect against foreign currency exchange rate risks inherent in its forecasted inventory purchases. The Company had 2 Other: The Company is exposed to potential gains or losses from foreign currency fluctuations affecting net investments and earning denominated in foreign currencies. The Company is particularly sensitive to currency exchange rate fluctuations for the following currencies: British pound sterling (GBP), Chinese renminbi (CYN), Euro, Malaysian ringgit (MYR), Polish zloty (PLN), South African Rand (ZAR), Thai baht (THB) and Turkish lira (TRY). When considered appropriate, the Company enters into foreign exchange derivative contracts to mitigate the risk of fluctuations on these exposures. The Company does not designate these contracts for hedge accounting treatment and the changes in fair value of these contracts are recorded in earnings. The Company recorded (gains) losses of $(1.2) million and $0.6 million in other non-operating income (deductions), net within the Consolidated Statements of Income for the years ended 2017 and 2016, respectively. There were no open contracts at December 31, 2017. There were 2 open foreign exchange contracts at December 31, 2016. The fair value of the 2016 foreign exchange contracts was not significant. |

Fair Value of Financial Instruments [Abstract] | |
Fair Value of Financial Instruments | Note 10. Fair Value of Financial Instruments Fair value is an exchange price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability. The Company follows a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs about which little or no market data exists, therefore requiring an entity to develop its own assumptions. 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 foreign exchange 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 following table sets forth by level within the fair value hierarchy the Company's financial assets and liabilities accounted for at fair value on a recurring basis at the end of each of the past two years. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. Fair Value Measurements Using Description Asset / (Liability) Balance at 12/31/17 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (millions of dollars) Deferred compensation plan assets $ 12.9 $ - $ 12.9 $ - Supplementary pension plan assets 11.6 - 11.6 - Interest rate swap 2.9 - 2.9 - Fair Value Measurements Using Description Asset / (Liability) Balance at 12/31/17 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (milliions of dollars) Money market funds $ 0.7 $ 0.7 $ - $ - The fair value of investment in the money market funds is determined by quoted prices in active markets and is categorized as Level 1. The fair value of foreign exchange contracts is 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. Deferred compensation and supplementary pension plan assets related to the acquisition of AMCOL businesses and are valued using quoted prices for similar assets in active markets. The Company does not have any financial assets or liabilities measured at fair value on a recurring basis categorized as Level 3, except for pension assets discussed in Note 13, and there were no transfers in or out of Level 3 during the year ended . There were also no changes to the Company's valuation techniques used to measure asset and liability fair values on a recurring basis. |

Long-Term Debt and Commitments | Note 12. Long-Term Debt and Commitments The following is a summary of long term debt: December 31, 2017 2016 (millions of dollars) Term Loan Facility- Variable Tranche due February 14, 2024, net of unamortized discount and deferred financing costs of $ 22.7 million and $ 25.8 million $ 655.3 $ 762.3 Term Loan Facility- Fixed Tranche due May 9, 2021, net of unamortized discount and deferred financing costs of $0.5 million and $0.6 million $ 299.5 $ 299.4 Japan Loan Facilities 5.6 5.8 China Loan Facilities 3.2 9.2 Total $ 963.6 $ 1,076.7 Less: Current maturities 3.8 6.8 Long-term debt $ 959.8 $ 1,069.9 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 million 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. Following the Second Amendment, 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 May 9, 2019. After the Second Amendment, 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 will bear interest at a rate equal to an adjusted LIBOR rate plus an applicable margin equal to 1.75% 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 loans under the fixed rate tranche of the Term Facility are subject to prepayment premiums in the event of certain prepayments prior to the third anniversary of the effective date of the First Amendment. 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 quarter period 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 December 31, 2017, there were no loans and $12.9 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. During 2017, the Company repaid $110 million on its Term Facility. The Company has four committed loan facilities for the funding of new manufacturing facilities in China, for a combined 94.8 million RMB and $1.8 million. In December 2016, the Company entered into a committed loan facility in Japan in the amount of 680 million Yen (approximately $6.0 million). As of December 31, 2017, on a combined basis, $8.8 million was outstanding. Principal will be repaid in accordance with the payment schedules ending in 2021. The Company repaid $6.9 million on these loans in 2017. As of December 31, 2017, the Company had $37.1 million in uncommitted short-term bank credit lines, of which approximately $6.3 million was in use. Short-term borrowings as of December 31, 2017 and 2016 were $6.3 million and $6.1 million, respectively. The weighted average interest rate on short-term borrowings outstanding as of December 31, 2017 and December 31, 2016 was 3.9% and 3.7 The aggregate maturities of long-term debt are as follows: $3.8 million in 2018; $0.6 million in 2019; $0.6 million in 2020, $304 million in 2021; $0.0 million in 2022 and $678 million thereafter. During 2017, 2016 and 2015, respectively, the Company incurred interest costs of $45.4 million, $56.5 million and $62.6 million, including $0.2 million, $0.1 million and $0.5 million, respectively, which were capitalized. Interest paid approximated the incurred interest cost. |

Benefit Plans [Abstract] | |
Benefit Plans | Note 13. Benefit Plans Pension Plans and Other Postretirement Benefit Plans The Company and its subsidiaries have pension plans covering the majority of eligible employees on a contributory or non-contributory basis. Benefits under defined benefit plans are generally based on years of service and an employee's career earnings. Employees generally become fully vested after five years. The Company also provides postretirement health care and life insurance benefits for the majority of its U.S. retired employees. Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. The Company does not pre-fund these benefits and has the right to modify or terminate the plan in the future. The Company’s 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 following table set forth Company's pension obligation and funded status at December 31: Pension Benefits Post-Retirement Benefits 2017 2016 2017 2016 (millions of dollars) Change in benefit obligations: Beginning projected benefit obligation $ 427.9 $ 416.6 $ 9.3 $ 9.3 Service cost 7.9 8.2 0.3 0.3 Interest cost 12.6 13.0 0.3 0.3 Actuarial (gain)/loss 31.5 21.2 (3.0 ) (0.6 ) Benefits paid (20.4 ) (18.3 ) (0.1 ) - Settlements - (0.9 ) Foreign exchange impact 9.6 (11.4 ) 0.1 - Other 0.4 (0.5 ) - Ending projected benefit obligation 469.5 427.9 6.9 9.3 Change in plan assets: Beginning fair value 289.3 282.5 - - Actual return on plan assets 33.8 22.9 - - Employer contributions 10.7 10.5 0.1 - Plan participants' contributions 0.4 0.4 - - Benefits paid (20.4 ) (18.3 ) (0.1 ) - Settlements (0.8 ) (0.5 ) - - Foreign exchange impact 7.2 (8.2 ) - - Ending fair value 320.2 289.3 - - Funded status of the plan $ (149.3 ) $ (138.6 ) $ (6.9 ) $ (9.3 ) Amounts recognized in the consolidated balance sheet consist of: Pension Benefits Post-Retirement Benefits 2017 2016 2017 2016 (millions of dollars) Current liability $ (0.8 ) $ (0.8 ) $ (0.5 ) $ (0.6 ) Non-current liability (148.5 ) (137.8 ) (6.4 ) (8.7 ) Recognized liability $ (149.3 ) $ (138.6 ) $ (6.9 ) $ (9.3 ) The current portion of pension liabilities is included in accrued compensation and related items. Amounts recognized in accumulated other comprehensive income, net of related tax effects, consist of: Pension Benefits Post-Retirement Benefits 2017 2016 2017 2016 (millions of dollars) Net actuarial (gain) loss $ 91.4 $ 82.1 $ (4.1 ) $ (1.7 ) Prior service cost (0.1 ) (0.1 ) (0.7 ) (2.4 ) Amount recognized end of year $ 91.3 $ 82.0 $ (4.8 ) $ (4.1 ) The accumulated benefit obligation for all defined benefit pension plans was $435.4 million and $394.5 million at December 31, 2017 and 2016, respectively. Changes in the Plan assets and benefit obligations recognized in other comprehensive income: Pension Benefits Post-Retirement Benefits 2017 2016 2017 2016 (millions of dollars) Current year actuarial gain (loss) $ (15.8 ) $ (8.7 ) $ 2.6 $ 0.3 Amortization of actuarial (gain) loss 7.2 6.8 (0.2 ) (0.1 ) Amortization of prior service credit (gain) loss - 0.4 (2.3 ) (1.9 ) Total recognized in other comprehensive income $ (8.6 ) $ (1.5 ) $ 0.1 $ (1.7 ) The components of net periodic benefit costs are as follows: Pension Benefits Post-Retirement Benefits 2017 2016 2015 2017 2016 2015 (millions of dollars) Service cost $ 7.9 $ 8.2 $ 10.3 $ 0.3 $ 0.3 $ 0.4 Interest cost 12.6 13.0 15.4 0.3 0.3 0.3 Expected return on plan assets (18.7 ) (18.6 ) (19.7 ) - - - Amortization of prior service cost - 0.6 0.8 (3.1 ) (3.1 ) (3.1 ) Recognized net actuarial (gain) loss 10.8 10.7 12.1 (0.3 ) (0.2 ) (0.1 ) Settlement/curtailment loss - 0.3 - - - - Net periodic benefit cost $ 12.6 $ 14.2 $ 18.9 $ (2.8 ) $ (2.7 ) $ (2.5 ) Unrecognized prior service cost is amortized over the average remaining service period of each active employee. The Company's funding policy for U.S. plans generally is to contribute annually into trust funds at a rate that provides for future plan benefits and maintains appropriate funded percentages. Annual contributions to the U.S. qualified plans are at least sufficient to satisfy regulatory funding standards and are not more than the maximum amount deductible for income tax purposes. The funding policies for the international plans conform to local governmental and tax requirements. The plans' assets are invested primarily in stocks and bonds. The 2018 estimated amortization of amounts in other accumulated comprehensive income are as follows: Pension Benefits Post-Retirement Benefits (millions of dollars) Amortization of prior service credit (gain) loss $ - $ (0.9 ) Amortization of net (gain) loss 11.5 (0.6 ) Total cost to be recognized $ 11.5 $ (1.5 ) Additional Information The weighted average assumptions used to determine net periodic benefit cost in the accounting for the pension benefit plans and other benefit plans for the years ended December 31, 2017, 2016 and 2015 are as follows: 2017 2016 2015 Discount rate 3.56 % 3.88 % 3.71 % Expected return on plan assets 6.61 % 6.89 % 6.89 % Rate of compensation increase 3.01 % 3.03 % 3.04 % The weighted average assumptions used to determine benefit obligations for the pension benefit plans and other benefit plans at December 31, 2017, 2016 and 2015 are as follows: 2017 2016 2015 Discount rate 3.16 % 3.60 % 3.89 % Rate of compensation increase 3.01 % 2.96 % 3.04 % For 2017, 2016 and 2015, the discount rate was based on a Citigroup yield curve of high quality corporate bonds with cash flows matching our plans' expected benefit payments. The expected return on plan assets is based on our asset allocation mix and our historical return, taking into account current and expected market conditions. The actual return on pension assets was approximately 11% in 2017, % in 2016 and 1% in 2015. The Company maintains a self-funded health insurance plan for its retirees. This plan provided that the maximum health care cost trend rate would be %. Effective June 2010, the Company amended its plan to change the eligibility requirement for retirees and revised its plan so that increases in expected health care costs would be borne by the retiree. Plan Assets The Company's pension plan weighted average asset allocation percentages at December 31, 2017 and 2016 by asset category are as follows: Asset Category 2017 2016 Equity securities 56.0 % 60.2 % Fixed income securities 36.2 % 32.7 % Real estate 0.8 % 0.7 % Other 7.0 % 6.4 % Total 100.0 % 100.0 % The Company's pension plan fair values at December 31, 2017 and 2016 by asset category are as follows: Asset Category 2017 2016 (millions of dollars) Equity securities $ 179.2 $ 174.1 Fixed income securities 116.0 94.7 Real estate 2.4 1.9 Other 22.6 18.6 Total $ 320.2 $ 289.3 The following table presents domestic and foreign pension plan assets information at December 31, 2017, 2016 and 2015 (the measurement date of pension plan assets): U.S. Plans International Plans 2017 2016 2015 2017 2016 2015 (millions of dollars) Fair value of plan assets $ 241.9 $ 221.9 $ 213.0 $ 78.3 $ 67.4 $ 69.5 The following table summarizes our defined benefit pension plan assets measured at fair value as of December 31, 2017: Pension Assets Fair Value as of December 31, 2017 Quoted Prices In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total (Level 1) (Level 2) (Level 3) (millions of dollars) Equity securities US equities $ 156.1 $ - $ - $ 156.1 Non-US equities 23.1 - - 23.1 Fixed income securities Corporate debt instruments 82.0 34.0 - 116.0 Real estate and other Real estate - - 2.4 2.4 Other 0.2 - 22.4 22.6 Total assets $ 261.4 $ 34.0 $ 24.8 $ 320.2 The following table summarizes our defined benefit pension plan assets measured at fair value as of December 31, 2016: Pension Assets Fair Value as of December 31, 2016 Quoted Prices In Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total (Level 1) (Level 2) (Level 3) (millions of dollars) Equity securities US equities $ 155.0 $ 0.2 $ - $ 155.2 Non-US equities 18.9 - - 18.9 Fixed income securities Corporate debt instruments 63.4 31.3 - 94.7 Real estate and other Real estate - - 1.9 1.9 Other - 0.2 18.4 18.6 Total assets $ 237.3 $ 31.7 $ 20.3 $ 289.3 U.S. equities Non-U.S. equities Fixed income— Real Estate and other— This class includes assets related to real estate and other assets such as insurance contracts . Asset classified as Level 1 are valued using quoted prices on major stock exchange on which individual assets are traded. Our Level 2 assets are valued using net asset value. The net asset value is quoted on a private market that is not active; however, the unit price is based on the underlying investments that are traded on an active market. Our Level 3 assets are estimated at fair value based on the most recent financial information available for the underlying securities, which are not traded on active market, and represents significant unobservable input. The following is a reconciliation of changes in fair value measurement of plan assets using significant unobservable inputs (Level 3): (millions of dollars) Beginning balance at December 31, 2015 $ 17.9 Purchases, sales, settlements - Actual return on plan assets still held at reporting date 3.0 Foreign exchange impact (0.6 ) Ending balance at December 31, 2016 $ 20.3 Purchases, sales, settlements - Actual return on plan assets still held at reporting date 3.9 Foreign exchange impact 0.5 Ending balance at December 31, 2017 $ 24.7 There were no transfers in or out of Level 3 during the year ended Contributions The Company expects to contribute $ million to its pension plans and $ million to its other post-retirement benefit plan in 2018. Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid: Pension Benefits Other Benefits (millions of dollars) 2018 $ 22.9 $ 0.5 2019 $ 24.3 $ 0.5 2020 $ 25.5 $ 0.5 2021 $ 25.4 $ 0.5 2022 $ 26.2 $ 0.5 2023-2026 $ 131.6 $ 2.7 Investment Strategies The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to both preserve and grow plan assets to meet future plan obligations. The Company's average rate of return on assets from inception through December 31, 2017 was over %. The Company’s assets are strategically allocated among equity, debt and other investments to achieve a diversification level that dampens fluctuations in investment returns. The Company’s long-term investment strategy is an investment portfolio mix of approximately 55%-65% in equity securities, 30%-35% in fixed income securities and 0%-15% in other securities. Savings and Investment Plans The Company maintains a voluntary Savings and Investment Plan (a 401(k) plan) for most non-union employees in the U.S. Within prescribed limits, the Company bases its contribution to the Savings and Investment Plan on employee contributions. The Company's contributions amounted to $5.2 million, $ million and $6.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. |

Litigation [Abstract] | |
Litigation | Note 15. Litigation The Company is party to a number of lawsuits arising in the normal course of our business. On May 8, 2013, Armada (Singapore) PTE Limited, an ocean shipping company now in bankruptcy ("Armada") filed a case in federal court in the Northern District of Illinois against AMCOL and certain of its subsidiaries ( Armada (Singapore) PTE Limited v. AMCOL International Corp., et al., United States District Court for the Northern District of Illinois 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 20 pending asbestos cases. To date, 1,493 silica cases and 53 asbestos cases have been dismissed, not including any lawsuits against AMCOL or American Colloid Company dismissed prior to our acquisition of AMCOL. Seven new asbestos cases were filed in 2017, including one that was previously reported on the Company’s 2016 Annual Report on Form 10-K. Four asbestos cases were dismissed during the period. No 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 or American Colloid, are reimbursed by Pfizer Inc. pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992. The Company is entitled to indemnification, pursuant to agreement, for sales prior to the initial public offering. Of the 20 pending asbestos cases, 13 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 the six remaining non-AMCOL cases, the plaintiffs have not alleged dates of exposure. The remaining case is an AMCOL case, which makes no allegation with respect to periods of exposure. 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 4 th 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 December 31, 2017. The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses. |

In January 2018, a cash dividend of approximately $ million or $0.05 per share, was Stock Award and Incentive Plan At the Company’s 2015 Annual Meeting of Stockholders, the Company’s stockholders ratified the adoption of the Company’s 2015 Stock Award and Incentive Plan (the “2015 Plan”), which provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards. The 2015 Plan is substantially similar to the Company’s 2001 Stock Award and Incentive Plan (as amended and restated as of March 18, 2009, the “2001 Plan” and collectively with the 2015 Plan, the “Plans”). The Company established the 2015 Plan to increase the total number of shares of common stock reserved and available for issuance by 880,000 shares from the number of shares remaining under the 2001 Plan. With the ratification of the 2015 Plan by the Company’s stockholders, the 2001 Plan was discontinued as to new grants (however, all awards previously granted under the 2001 Plan remained unchanged). The Plans are administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plan have a term not in excess of ten years. The exercise price for stock options will not be less than the fair market value of the common stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years. The following table summarizes stock option and restricted stock activity for the Plans: Stock Options Restricted Shares Shares Available for Grant Shares Weighted Average Exercise Price Per Share ($) Shares Weighted Average Exercise Price Per Share ($) Balance January 1, 2015 996,127 951,079 $ 37.46 175,488 $ 50.56 Authorized 880,000 - - - - Granted (455,275 ) 238,773 60.40 216,502 60.32 Exercised/vested - (74,839 ) 33.12 (59,801 ) 47.51 Canceled 71,113 (23,169 ) 60.22 (47,944 ) 51.43 Balance December 31, 2015 1,491,965 1,091,844 42.29 284,245 58.63 Granted (538,787 ) 383,622 38.59 155,165 38.37 Exercised/vested - (150,944 ) 36.66 (88,746 ) 57.38 Canceled 249,248 (125,797 ) 43.78 (123,451 ) 50.72 Balance December 31, 2016 1,202,426 1,198,725 41.66 227,213 49.57 Granted (257,072 ) 187,533 77.99 69,539 78.00 Exercised/vested - (353,636 ) 41.56 (61,274 ) 52.51 Canceled 91,151 (35,783 ) 50.47 (55,368 ) 52.74 Balance December 31, 2017 1,036,505 996,839 48.21 180,110 58.57 |

Accounting for Asset Retirement Obligations [Abstract] | |
Accounting for Asset Retirement Obligations | Note 18. Accounting for Asset Retirement Obligations The Company records asset retirement obligations in which the Company will be required to retire tangible long-lived assets. These are primarily related to its PCC satellite facilities and mining operations. The Company has also recorded the provisions related to conditional asset retirement obligations at its facilities. The Company has recorded asset retirement obligations at all of its facilities except where there are no contractual or legal obligations. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The following is a reconciliation of asset retirement obligations as of December 31, 2017 and 2016: 2017 2016 (millions of dollars) Asset retirement liability, beginning of period $ 21.5 $ 21.4 Accretion expense 3.3 2.5 Payments (3.2 ) (1.6 ) Foreign currency translation 0.5 (0.8 ) Asset retirement liability, end of period $ 22.1 $ 21.5 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. This liability will be adjusted to reflect the passage of time, mining activities, and changes in estimated future cash outflows The current portion of the liability of approximately $1.6 million is included in other current liabilities and the long-term portion of the liability of approximately $20.5 million is included in other non-current liabilities in the Consolidated Balance Sheet as of December 31, 2017. Accretion expense is included in cost of goods sold in the Company's Consolidated Statements of Income. |

Segment and Related Information [Abstract] | |
Segment and Related Information | Note 19. Segment and Related Information The Company determines its operating segments based on the discrete financial information that is regularly evaluated by its chief operating decision maker, our Chief Executive Officer, in deciding how to allocate resources and in assessing performance. Accordingly, in the first quarter of 2017, the Company reorganized the management structure for its Performance Materials and Construction Technologies business units to better reflect the way performance is evaluated and resources are allocated. As a result, all of the product lines within these business segments were combined into one operating segment. The Company's operating segments are strategic business units that offer different products and serve different markets. They are managed separately and require different technology and marketing strategies. The Company now has four reportable segments: Specialty Minerals, Refractories, Performance Materials and Energy Services. - 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 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 Energy Services segment provides services to improve the production, costs, compliance, and environmental impact of activities performed in oil and gas industry. This segment offers a range of services for off-shore filtration and well testing to the worldwide oil and gas industry. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates performance based on the operating income of the respective business units. The costs deducted to arrive at operating profit do not include several items, such as net interest or income tax expense. Depreciation expense related to corporate assets is allocated to the business segments and is included in their income from operations. However, such corporate depreciable assets are not included in the segment assets. Intersegment sales and transfers are not significant. Segment information for the years ended December 31, 2017, 2016 and 2015 was as follows: 2017 2016 2015 (millions of dollars) Net Sales Specialty Minerals $ 584.8 $ 591.5 $ 624.6 Performance Materials 734.8 686.1 694.9 Refractories 279.4 274.5 295.9 Energy Services 76.7 85.9 182.2 Total 1,675.7 1,638.0 1,797.6 Income from Operations Specialty Minerals 88.9 102.7 100.8 Performance Materials 119.7 121.1 118.4 Refractories 39.8 37.0 27.8 Energy Services 6.1 (25.9 ) (27.9 ) Total 254.5 234.9 219.1 Depreciation, Depletion and Amortization Specialty Minerals 35.5 34.9 34.0 Performance Materials 40.5 38.9 39.4 Refractories 6.8 6.9 7.5 Energy Services 8.2 11.2 17.4 Total 91.0 91.9 98.3 Segment Assets Specialty Minerals 519.4 491.7 505.3 Performance Materials 1,989.6 1,942.1 1,965.4 Refractories 307.4 283.4 292.7 Energy Services 110.6 104.7 154.7 Total 2,927.0 2,821.9 2,918.1 Capital Expenditures Specialty Minerals 32.6 40.4 51.9 Performance Materials 33.1 12.8 11.1 Refractories 5.9 5.9 11.1 Energy Services 4.5 1.4 11.1 Total 76.1 60.5 85.2 A reconciliation of the totals reported for the operating segments to the applicable line items in the consolidated financial statements is as follows: 2017 2016 2015 (millions of dollars) Income from Operations before Provision (Benefit) for Taxes on Income Income from operations for reportable segments $ 254.5 $ 234.9 $ 219.1 Acquisition related transaction and integration costs (3.4 ) (8.0 ) (11.8 ) Unallocated corporate expenses (8.4 ) (6.0 ) (7.0 ) Consolidated income from operations 242.7 220.9 200.3 Non-operating deductions, net (51.8 ) (50.6 ) (67.7 ) Income from continuing operations before provision (benefit) for taxes on income 190.9 170.3 132.6 Total Assets Total segment assets 2,927.0 2,821.9 2,918.1 Corporate assets 43.4 41.5 61.9 Consolidated total assets 2,970.4 2,863.4 2,980.0 Capital Expenditures Total segment capital expenditures 76.1 60.5 85.2 Corporate capital expenditures 0.6 1.9 0.8 Consolidated capital expenditures 76.7 62.4 86.0 Financial information relating to the Company's operations by geographic area was as follows: 2017 2016 2015 (millions of dollars) Net Sales United States $ 939.3 $ 936.2 $ 1,049.6 Canada/Latin America 81.6 82.6 86.3 Europe/Africa 349.0 338.8 382.1 Asia 305.8 280.4 279.6 Total International 736.4 701.8 748.0 Consolidated net sales 1,675.7 1,638.0 1,797.6 Long-Lived Assets United States $ 1,774.4 $ 1,794.5 $ 1,829.3 Canada/Latin America 14.8 14.8 13.0 Europe/Africa 115.9 98.2 117.6 Asia 132.0 127.3 138.3 Total International 262.7 240.3 268.9 Consolidated long-lived assets 2,037.1 2,034.8 2,098.2 Net sales and long-lived assets are attributed to countries and geographic areas based on the location of the legal entity.

Summary of Significant Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of Minerals Technologies Inc. (the "Company"), its wholly and majority-owned subsidiaries, as well as variable interest entities for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. |
Use of Estimates | 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, pension plan assumptions, income tax, and litigation and environmental liabilities. Actual results could differ from those estimates. |
Cash Equivalents and Short-term Investments | Cash Equivalents and Short-term Investments The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Short-term investments consist of financial instruments, mainly bank deposits, with original maturities beyond three months, but less than twelve months. Short-term investments amounted to $2.7 were no unrealized holding gains and losses on the short-term bank investments held at . |
Trade Accounts Receivable | Trade Accounts Receivable Trade accounts receivables are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific allowances for bankrupt customers. The Company also analyzes the collection history and financial condition of its other customers, considering current industry conditions and determines whether an allowance needs to be established. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days based on payment terms are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers. |
Inventories | Inventories Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. Additionally, items such as idle facility expense, excessive spoilage, freight handling costs, and re-handling costs are recognized as current period charges. The allocation of fixed production overheads to the costs of conversion are based upon the normal capacity of the production facility. Fixed overhead costs associated with idle capacity are expensed as incurred. |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. The straight-line method of depreciation is used for substantially all of the assets for financial reporting purposes, except for mining related equipment which uses units-of-production method. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets. The estimated useful lives of our PCC production facilities and machinery and equipment pertaining to our natural stone mining and processing plants and our chemical plants are 15 years. Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of PCC are predominantly pursuant to long-term evergreen contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge or accelerated depreciation at such facility. Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes, based upon proven and probable reserves, and on a percentage depletion basis for tax purposes. |
Stripping Costs Incurred During Production | Stripping Costs Incurred During Production Stripping costs are those costs incurred for the removal of waste materials for the purpose of accessing ore body that will be produced commercially. Stripping costs incurred during the production phase of a mine are variable costs that are included in the costs of inventory produced during the period that the stripping costs are incurred. |
Accounting for the Impairment of Long-Lived Assets | Accounting for the Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, the Company estimates the undiscounted future cash flows (excluding interest), resulting from the use of the asset and its ultimate disposition. If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset, determined principally using discounted cash flows. |
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. Goodwill is not amortized, but instead assessed for impairment. Intangible assets with estimable useful lives are amortized on a straight-line basis over their respective estimated lives to the estimated residual values, and reviewed for impairment. The Company performs a qualitative assessment for each of its reporting units to determine if the two step process for impairment testing is required. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company would then evaluate the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the fair value for the reporting unit is compared to its book value including goodwill. In the case that the fair value of the reporting unit is less than book value, a second step is performed which compares the fair value of the reporting unit's goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values of the reporting unit and the net fair values of the identifiable assets and liabilities of such reporting unit. If the fair value of the goodwill is less than the book value, the difference is recognized as impairment. |
Investment in joint ventures | Investment in joint ventures The Company uses the equity method of accounting to incorporate the results of its investments in companies in which it has significant influence, but does not control; and cost method of accounting in companies in which it cannot exercise significant control. The Company records the equity in earnings of its investments in joint ventures on a one month lag. At December 31, 2017, the book value of Company’s equity method investment was $16.1 million. The Company had no cost method investments at December 31, 2017. |
Accounting for Asset Retirement Obligations | Accounting for Asset Retirement Obligations The Company provides for obligations associated with the retirement of long-lived assets and the associated asset retirement costs. The fair value of a 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 associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company also provides for legal obligations to perform asset retirement activities where timing or methods of settlement are conditional on future events. The Company also records liabilities related to land reclamation as a part of the asset retirement obligations. The Company mines land for various minerals using a surface-mining process that requires the removal of overburden. In many instances, the Company is obligated to restore the land upon completion of the mining activity. As the overburden is removed, the Company recognizes this liability for land reclamation based on the estimated fair value of the obligation. The obligation is adjusted to reflect the passage of time and changes in estimated future cash outflows. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The recorded amounts of cash and cash equivalents, receivables, short-term borrowings, accounts payable, accrued interest, and variable-rate long-term debt approximate fair value because of the short maturity of those instruments or the variable nature of underlying interest rates. Short-term investments are recorded at cost, which approximates fair market value. |
Derivative Financial Instruments | Derivative Financial Instruments The Company records derivative financial instruments which are used to hedge certain foreign exchange risk at fair value on the balance sheet. See Note 9 for a full description of the Company's hedging activities and related accounting policies. |
Revenue Recognition | Revenue Recognition Revenue from sale of products is recognized when title passes to the customer, the customer assumes the risks and rewards of ownership, and collectability is reasonably assured; generally, this occurs when the goods are shipped to the customer. 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 those 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. Revenue from sales of equipment is recorded upon completion of installation and receipt of customer acceptance. Revenue from services is recorded when the services have been performed and collectability is reasonably assured. Revenue from long-term construction contracts is recorded using the percentage-of-completion method. Progress is generally based upon costs incurred to date as compared to the total estimated costs to complete the work under the contract or the amount of product installed in relation to the total amount expected to be installed. All known or anticipated losses on contracts are provided when they become evident. Cost adjustments that are in the process of being negotiated with customers for extra work or changes in scope of work are included in revenue when collection is reasonably assured. |
Foreign Currency | Foreign Currency The assets and liabilities of the Company's international subsidiaries are translated into U.S. dollars using exchange rates at the respective balance sheet date. The resulting translation adjustments are recorded in accumulated other comprehensive income (loss) in shareholders' equity. Income statement items are generally translated at monthly average exchange rates prevailing during the period. International subsidiaries operating in highly inflationary economies translate non-monetary assets at historical rates, while net monetary assets are translated at current rates, with the resulting translation adjustments included in net income. At December 31, 2017, the Company had no international subsidiaries operating in highly inflationary economies. |
Income Taxes | Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company operates in multiple taxing jurisdictions, both within the U.S. 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 regularly assesses its tax position for such transactions and includes reserves for those differences in position. The reserves are utilized or reversed once the statute of limitations has expired or the matter is otherwise resolved. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations. The Company's accounting policy is to recognize interest and penalties as part of its provision for income taxes. See Note 5 for additional detail on our uncertain tax positions. The accompanying financial statements do not include a provision for foreign withholding taxes on international subsidiaries' unremitted earnings, which are expected to be permanently reinvested overseas. |
Research and Development | Research and Development Research and development costs are expensed as incurred. |
Accounting for Stock-Based Compensation | Accounting for Stock-Based Compensation The Company recognizes compensation expense for share-based awards based upon the grant date fair value over the vesting period. |
Pension and Post-retirement Benefits | Pension and Post-retirement Benefits The Company has defined benefit pension plans covering the majority of its employees. The benefits are generally based on years of service and an employee's modified career earnings. The Company also provides post-retirement healthcare benefits for the majority of its retirees and employees in the United States. The Company measures the costs of its obligation based on its best estimate. The net periodic costs are recognized as employees render the services necessary to earn the post-retirement benefits. |
Environmental | Environmental Expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and which do not contribute to current or future revenue generation are expensed. Liabilities are recorded when it is probable the Company will be obligated to pay amounts for environmental site evaluation, remediation or related costs, and such amounts can be reasonably estimated. |
Earnings Per Share | Earnings Per Share Basic earnings per share have been computed based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share have been computed based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding. |
Subsequent Events | Subsequent Events The Company has evaluated for subsequent events through the date of issuance of its financial statements. |
Recently Issued Accounting Standards | 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. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” which will supersede nearly all existing revenue recognition guidance under U.S. GAAP. 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 guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2017. The guidance permits the use of either a retrospective or cumulative effect transition method. The Company has completed its evaluation of the provisions of this standard and we have concluded that our adoption of ASU No. 2014-09 will not materially change the amount or timing of revenues recognized by us, nor will it materially affect our financial position. We have adopted this new standard effective January 1, 2018. The Company has elected to use the cumulative effect transition method and there will not be a change to our previously reported financial results. 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 is currently evaluating the impact of this ASU on the Company’s consolidated financial statements and related disclosures. Based on the current status of this assessment, the adoption of this guidance 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2019, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements. Compensation – Retirement Benefits In March 2017, the FASB issued 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 guidance is effective for the interim and annual periods beginning on or after December 15, 2017. We adopted this new standard effective January 1, 2018. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements. Derivatives and Hedging In August 2017, the FASB issued accounting guidance to improve and simplify existing guidance to allow companies to better reflect their risk management activities in the financial statements. The guidance 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 guidance is not expected to have a material impact on the Company’s financial statements. Adoption of ASU 2016-09, Stock Compensation- Improvements to Employee Share-Based Payment Accounting On January 1, 2017, the Company adopted the provisions of ASU 2016-09, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting”, an amendment to account standards codification (“ASC”) 718, which simplifies several aspects of accounting for share-based payments, including accounting for income taxes, forfeitures, statutory withhold rates as well as presentation on the statement of cash flows. The Company has elected to adopt the standard on a prospective basis. As a result of this adoption, the Company recognizes excess tax benefits in the current account period. The cash flow benefit of the excess tax benefit is included as an operating activity in the Consolidated Statement of Cash Flows for the period ended December 31, 2017. Additionally, taxes paid for shares withheld for tax-withholding purposes are reported as financing activities in the Condensed Consolidated Statements of Cash Flows. Previously, this activity was included in operating activities. Prior year Condensed Consolidated Statement of Cash Flows has not been restated. In accordance with the standard, the Company will continue to account for forfeitures using an estimated forfeiture rate. |
