Accounting Policies [Abstract]
Summary of Accounting Policies	—Summary of Accounting Policies Nature of Business Carlisle Companies Incorporated, its wholly owned subsidiaries and their subsidiaries, referred to herein as the “Company” or “Carlisle,” is a global diversified company that designs, manufactures and markets a wide range of products that serve a broad range of markets including commercial roofing, energy, agriculture, mining, construction, aerospace and defense electronics, medical technology, transportation, general industrial, protective coatings, wood and auto refinishing. The Company markets its products as a component supplier to original equipment manufacturers, distributors and directly to end-users. Basis of Presentation The consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany transactions and accounts have been eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“United States” or “U.S.”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Matters The functional currency of the Company’s subsidiaries outside the United States is the currency of the primary economic environment in which the subsidiary operates. Assets and liabilities of these operations are translated to the U.S. Dollar at the exchange rate in effect at each balance sheet date. Income statement accounts are translated at the average rate of exchange prevailing during the year. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of shareholders’ equity in accumulated other comprehensive income (loss). Gains and losses from foreign currency transactions and from the remeasurement of monetary assets and liabilities and associated income statement activity of foreign subsidiaries where the functional currency is the U.S. Dollar and the records are maintained in the local currency are included in other non-operating (income) expense, net. Discontinued Operations The results of operations for the Company's Carlisle FoodService Products ("CFS") segment have been classified as discontinued operations for all periods presented in the Condensed Consolidated Statements of Income. Assets and liabilities subject to the completed sale of CFS have been classified as discontinued operations for all periods presented in the Condensed Consolidated Balance Sheets. Refer to Note 4 for additional information. Revenue Recognition Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; generally, this occurs with the transfer of control of the Company’s products or services. Revenue is measured as the amount of total consideration expected to be received in exchange for transferring goods or providing services. Total expected consideration, in certain cases, is estimated at each reporting period, including interim periods, and is subject to change with variability dependent on future events, such as customer behavior related to future purchase volumes, returns, early payment discounts and other customer allowances. Estimates for rights of return, discounts and rebates to customers and other adjustments for variable consideration are provided for at the time of sale as a deduction to revenue, based on an analysis of historical experience and actual sales data. Changes in these estimates are reflected as an adjustment to revenue in the period identified. Sales, value added and other taxes collected concurrently with revenue-producing activities are excluded from revenue. The Company receives payment at the inception of the contract for separately priced extended service warranties, and revenue is deferred and recognized on a straight-line basis over the life of the contracts. The term of these warranties ranges from five to 40 years. The weighted average life of the contracts as of December 31, 2018, is approximately 19 years. The Company recognizes revenue over-time for certain contracts that provide for the manufacture of highly-customized products with no alternative use and provide the Company the right to payment for work performed to date, including a normal margin for that effort. Refer to Note 6 for further information on revenue recognition. Costs to Obtain a Contract Costs of obtaining or fulfilling a contract are recognized as expense as incurred, as the amortization period of these costs would be one year or less. These costs generally include sales commissions and are included in selling, general and administrative costs. Shipping and Handling Costs Costs incurred to physically transfer product to customer locations are recorded as a component of cost of goods sold. Charges passed on to customers are recorded into revenues. Other Non-operating (Income) Expense, Net Other non-operating (income) expense, net primarily includes foreign currency exchange (gains) losses, indemnification (gains) losses associated with acquired businesses, (income) loss from equity method investments and (gains) losses on sales of a business. Stock‑Based Compensation The Company accounts for stock‑based compensation under the fair‑value method. Accordingly, equity classified as stock‑based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. The requisite service period generally matches the stated vesting period of the award but may be shorter if the employee is retirement‑eligible and, under the award’s terms, may fully vest upon retirement from the Company. The Company recognizes expense for awards that have graded vesting features under the graded vesting method, which considers each separately vesting tranche as though they were, in substance, multiple awards. Additionally, the Company accounts for forfeitures of stock-based awards as they occur. Refer to Note 7 for additional information regarding stock-based compensation. Income Taxes Income taxes are recorded in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes , which includes an estimate of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Deferred tax assets and liabilities reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Refer to Note 9 for additional information regarding income taxes including Staff Accounting Bulletin 118 (“SAB 118”) impacts. Cash Equivalents Highly liquid investments with a maturity of three months or less when acquired are considered cash equivalents. Receivables and Allowance for Doubtful Accounts Receivables are stated at net realizable value. The Company performs ongoing evaluations of its customers’ current creditworthiness, as determined by the review of their credit information to determine if events have occurred subsequent to the recognition of the revenue and related receivable that provides evidence that such receivable will be realized at an amount less than that recognized at the time of sale. Estimates of net realizable value are based on historical losses, adjusting for current economic conditions and, in some cases, evaluating specific customer accounts for risk of loss. The allowance for doubtful accounts was $5.1 million , $6.5 million and $3.9 million as of December 31, 2018 , 2017 and 2016 , respectively. Changes in economic conditions in specific markets in which the Company operates could have an effect on reserve balances required and on the ability to recognize revenue until cash is collected or collectability is probable. Changes in the Company's allowance for doubtful accounts follows: (in millions) 2018 2017 2016 Balance as of January 1 $ 6.5 $ 3.9 $ 4.7 (Decrease) increase to reserve (0.5 ) 1.2 0.1 Amounts acquired — 2.0 0.4 Amounts written off (0.9 ) (0.6 ) (1.3 ) Balance as of December 31 $ 5.1 $ 6.5 $ 3.9 Inventories Inventories are valued at lower of cost and net realizable value with cost determined primarily on an average cost basis. Cost of inventories includes direct as well as certain indirect costs associated with the acquisition and production process. These costs include raw materials, direct and indirect labor and manufacturing overhead. Manufacturing overhead includes materials, depreciation and amortization related to property, plant and equipment and other intangible assets used directly and indirectly in the acquisition and production of inventory, and costs related to the Company’s distribution network such as inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs and other such costs associated with preparing the Company’s products for sale. Refer to Note 10 for further information regarding inventories. Property, Plant and Equipment Property, plant and equipment are stated at cost including interest costs associated with qualifying capital additions. Costs allocated to property, plant and equipment of acquired companies are based on estimated fair value at the date of acquisition. Depreciation is principally computed on a straight‑line basis over the estimated useful lives of the assets. Asset lives are generally 20 to 40 years for buildings, five to 15 years for machinery and equipment and two to 20 years for leasehold improvements. Leasehold improvements are amortized based on the shorter of the underlying lease term or the asset’s estimated useful life. Refer to Note 11 for further information regarding property, plant and equipment. Valuation of Long‑Lived Assets Long‑lived assets or asset groups, including amortizable intangible assets, are tested for impairment whenever events or circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. The Company groups its long‑lived assets classified as held and used at the lowest level for which identifiable cash flows are largely independent of the cash flows from other assets and liabilities for purposes of testing for impairment. The Company’s asset groupings vary based on the related business in which the long‑lived assets are employed and the interrelationship between those long‑lived assets in producing net cash flows; for example, multiple manufacturing facilities may work in concert with one another or may work on a stand‑alone basis to produce net cash flows. The Company utilizes its long‑lived assets in multiple industries and economic environments and its asset groupings reflect these various factors. The Company monitors the operating and cash flow results of its long‑lived assets or asset groups classified as held and used to identify whether events and circumstances indicate the remaining useful lives of those assets should be adjusted or if the carrying value of those assets or asset groups may not be recoverable. Undiscounted estimated future cash flows are compared with the carrying value of the long‑lived asset or asset group in the event indicators of impairment are identified. If the undiscounted estimated future cash flows are less than the carrying amount, the Company determines the fair value of the asset or asset group and records an impairment charge in current earnings to the extent carrying value exceeds fair value. Fair values may be determined based on estimated discounted cash flows by prices for like or similar assets in similar markets or a combination of both. Long‑lived assets or asset groups that are part of a disposal group that meets the criteria to be classified as held for sale are not assessed for impairment, but rather a loss is recorded against the disposal group if fair value, less cost to sell, of the disposal group is less than its carrying value. Goodwill and Other Intangible Assets Intangible assets are recognized and recorded at their acquisition date fair values. Intangible assets that are subject to amortization are amortized on a straight-line basis over their useful lives. Definite-lived intangible assets consist primarily of acquired customer relationships, patents and technology, certain trade names and non-compete agreements. The Company determines the useful life of its definite-lived intangible assets based on multiple factors including the size and make-up of the acquired customer base, the expected dissipation of those customers over time, the Company’s own experience in the particular industry, the impact of known trends such as technological obsolescence, product demand or other factors and the period over which expected cash flows are used to measure the fair value of the intangible asset at acquisition. The Company periodically re-assesses the useful lives of its definite-lived intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Intangible assets with indefinite useful lives are not amortized but are tested annually, or more often if impairment indicators are present, for impairment via a one-step process by comparing the fair value of the intangible asset with its carrying value. If the intangible asset’s carrying value exceeds its fair value, an impairment charge is recorded in current earnings for the excess. The Company estimates the fair value of its indefinite-lived intangible assets based on the income approach utilizing the discounted cash flow method. The Company’s annual testing date for indefinite-lived intangible assets is October 1. The Company periodically re-assesses indefinite-lived intangible assets as to whether their useful lives can be determined and, if so, begins amortizing any applicable intangible asset. Goodwill is not amortized but is tested annually, or more often if impairment indicators are present, for impairment at a reporting unit level. The Company’s annual testing date for goodwill is October 1st. The Company has four reporting units, that align with its reportable segments. Refer to Note 12 for additional information regarding goodwill and other intangible assets. Pension The Company maintains defined benefit pension plans primarily for certain domestic employees. The annual net periodic benefit cost and projected benefit obligations related to these plans are determined on an actuarial basis annually on December 31, unless a remeasurement event occurs in an interim period. This determination requires assumptions to be made concerning general economic conditions (particularly interest rates), expected return on plan assets, increases to compensation levels and mortality rate trends. Changes in the assumptions to reflect actual experience can result in a change in the net periodic benefit cost and projected benefit obligations. The defined benefit pension plans’ assets are measured at fair value annually on December 31, unless a remeasurement event occurs in an interim period. The Company uses the market related valuation method to determine the value of plan assets for purposes of determining the expected return on plan assets component of net periodic benefit cost. The market related valuation method recognizes the change of the fair value of the plan assets over five years. If actual experience differs from these long-term assumptions, the difference is recorded as an actuarial gain (loss) and amortized into earnings over a period of time based on the average future service period, which may cause the expense related to providing these benefits to increase or decrease. Refer to Note 15 for additional information regarding these plans and the associated plan assets. Lease Arrangements The Company is a party to various lease arrangements that include scheduled rent increases, rent holidays or may provide for contingent rentals or incentive payments to be made to the Company as part of the terms of the lease. Scheduled rent increases and rent holidays are included in the determination of minimum lease payments when assessing lease classification and, along with any lease incentives, are included in rent expense on a straight‑line basis over the lease term. Scheduled rent increases that are dependent upon a change in an index or rate such as the consumer price index or prime rate are included in the determination of rental expense at the time the rate or index changes. Contingent rentals are excluded from the determination of minimum lease payments when assessing lease classification and are included in the determination of rent expense when the event that will require additional rents is considered probable. Refer to Note 17 for additional information regarding rent expense. Extended Product Warranty Reserves The Company offers extended warranty contracts on sales of certain products; the most significant being those offered on its installed roofing systems within the CCM segment. Current costs of services performed under these contracts are expensed as incurred and included in cost of goods sold. The Company would record a reserve within accrued expenses if the total expected costs of providing services at a product line level exceed unamortized deferred revenues. Total expected costs of providing extended product warranty services are actuarially determined using standard quantitative measures based on historical claims experience and management judgment. Refer to Notes 6 and 13 for additional information regarding deferred revenue and extended product warranties. Contingencies and Insurance Recoveries The Company is exposed to losses related to various potential claims related to its employee obligations and other matters in the normal course of business, including commercial, employee or regulatory litigation. The Company records a liability related to such potential claims, both those reported to the Company and incurred but not yet reported, when probable and reasonably estimable. With respect to workers’ compensation obligations, the Company utilizes actuarial models to estimate the ultimate total cost of such claims, primarily based on historical loss experience and expectations about future costs of providing workers’ compensation benefits. The Company maintains occurrence‑based insurance contracts related to certain contingent losses primarily workers’ compensation, medical and dental, general liability, property and product liability claims up to applicable retention limits as part of its risk management strategy. The Company records a recovery under these insurance contracts when such recovery is deemed probable. Refer to Note 17 for additional information regarding contingencies and insurance recoveries. Derivative Instruments and Hedge Accounting From time-to-time, the Company may enter into derivative financial instruments to hedge various risks to cash flows or the fair value of recognized assets and liabilities, including those arising from fluctuations in foreign currencies, interest rates and commodities. The Company recognizes these instruments at the time they are entered into and measures them at fair value. For instruments that are designated and qualify as cash flow hedges under U.S. GAAP, the changes in fair value period-to-period, less any ineffective portion, are classified in accumulated other comprehensive income, until the underlying transaction being hedged impacts earnings. Any ineffectiveness is recorded in current period income. For those instruments that are designated and qualify as fair value hedges under U.S. GAAP, the changes in fair value period-to-period of both the derivative instrument and underlying hedged item are recognized currently in earnings. For those instruments not designated or do not qualify as hedges under U.S. GAAP, the changes in fair value period-to-period are classified immediately in current period income, within other non-operating (income) expense, net. Refer to Note 18 for a description of the Company's current derivative instrument and hedging activities. New Accounting Standards Adopted Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which outlines a single, comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance issued by the FASB, including industry specific guidance. ASU 2014-09 provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts with customers to provide goods and services. In addition to ASU 2014-09, the Company also adopted all the related amendments ("ASC 606") to all uncompleted contracts using the modified retrospective method. The Company recognized the cumulative effect of initially applying ASC 606 as an adjustment to the opening balance of retained earnings totaling $6.5 million . The comparative information has not been adjusted and continues to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of ASC 606 to be immaterial to its reported revenue on an ongoing basis. A majority of the Company's revenues continue to be recognized when products are shipped from its manufacturing facilities or delivered to the customer, depending on shipping terms. For certain highly customized product contracts in the Carlisle Interconnect Technologies segment, revenue was previously recognized as billed, at the point products were shipped and title and associated risk and rewards of ownership passed to the customer. In accordance with ASC 606, the Company now recognizes revenue over time, for those highly customized products, using the input method as products are manufactured. A summary of the effects of adopting ASC 606 on the Consolidated Financial Statements follows: Year Ended December 31, 2018 (in millions) As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Consolidated Statement of Income Revenues $ 4,479.5 $ 4,457.6 $ 21.9 Cost of goods sold 3,304.8 3,290.1 14.7 Operating income 509.0 501.8 7.2 Provision for income taxes 87.3 85.5 1.8 Income from continuing operations 358.6 353.2 5.4 Net income 611.1 605.7 5.4 December 31, 2018 (in millions) As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Consolidated Balance Sheet Receivables $ 698.3 $ 654.0 $ 44.3 Inventories, net 457.5 487.0 (29.5 ) Other current assets 75.3 74.4 0.9 Accrued expenses 258.0 256.2 1.8 Other long-term liabilities 266.5 264.5 2.0 Retained earnings 3,351.4 3,344.9 6.5 Effective January 1, 2018, the Company adopted ASU 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"), which requires employers to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating income, if such measure is presented. The Company adopted ASU 2017-07 using a retrospective approach for the presentation in the Condensed Consolidated Statement of Income. The Company elected to use, as a practical expedient, the amounts disclosed in its defined benefit plan note for the prior comparative period as the estimation basis for applying the retrospective presentation requirements. As a result of adopting ASU 2017-07, net periodic benefit income for the non-service cost components of $(2.4) million was reclassified from other operating (income) expense, net to other non-operating (income) expense, net for the years ended December 31, 2017 and 2016. Effective January 1, 2018, the Company early adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"), which allows entities to reclassify from accumulated other comprehensive income to retained earnings for stranded tax effects related to the change in federal tax rate for all items accounted for in other comprehensive income. Entities can also elect to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act, but do not directly relate to the change in the federal tax rate, including state taxes and changing from a worldwide tax system to a territorial system. Tax effects that are stranded in other comprehensive income for other reasons may not be reclassified. The Company adopted ASU 2018-02 using a modified retrospective approach for the presentation in the Condensed Consolidated Balance Sheets to reclassify $6.5 million related to the change in federal tax rate from accumulated other comprehensive loss to retained earnings. Effective October 1, 2018, the Company early adopted ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic: 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans ("ASU 2018-14"), which makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and other postretirement benefit plans. The guidance requires all sponsors of defined benefit plans to disclose the weighted-average interest crediting rate for cash balance plans and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The guidance also eliminates the required disclosures for the amounts in accumulated other comprehensive income expected to be recognized as components of net period benefit cost over the next fiscal year. The Company adopted ASU 2018-14 using a retrospective approach for the revised disclosure requirements. New Accounting Standards Issued But Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02") which requires lessees to recognize a lease liability for the obligation to make lease payments, measured at the present value on a discounted basis, and a right-of-use ("ROU") asset for the right to use the underlying asset for the duration of the lease term, measured as the lease liability amount adjusted for lease prepayments, lease incentives received, and initial direct costs. The lease liability and ROU asset are recognized in the balance sheet at the commencement of the lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. Classification will be based on criteria that are largely similar to those applied in current lease accounting. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which amended the new leasing standard to give entities another option for transition. This transition option allows entities to not apply the new standard in the comparative periods they present in their financial statements in the year of adoption. ASU 2016-02, and its amendments, are effective for the Company beginning January 1, 2019, and requires the use of a modified retrospective approach for leases that exist at, or are entered into after the beginning of the year of adoption under the new transition guidance. Early application of the ASU is permitted; however, the Company plans to adopt on January 1, 2019 and expects to elect this new transition method. The Company continues its evaluation of adopting the standard, and currently expects the standard to have an impact of approximately $55.0 million to $65.0 million

Business Combinations [Abstract]
Acquisitions	—Acquisitions 2017 Acquisitions Accella Holdings LLC On November 1, 2017 , the Company acquired 100% of the equity of Accella Holdings LLC, the parent company to Accella Performance Materials Inc. (collectively “Accella”), a specialty polyurethane platform, from Accella Performance Materials LLC, a subsidiary of Arsenal Capital Partners, for total consideration of $671.4 million , including a cash, working capital and indebtedness settlement, which was finalized in the first quarter of 2018. Accella offers a wide range of polyurethane products and solutions across a broad diversity of markets and applications. The Company funded the acquisition with borrowings from the Revolving Credit Facility (refer to Note 14 for subsequent refinancing transactions). Accella contributed revenues of $434.1 million and an operating loss of $7.8 million for the year ended December 31, 2018 , and revenues of $64.0 million and an operating loss of $9.0 million for the period from November 1, 2017, to December 31, 2017. The operating loss for the period from November 1, 2017, to December 31, 2017, includes $5.5 million of incremental cost of goods sold related to measuring inventory at fair value and $1.1 million of acquisition-related costs related primarily to professional fees. The results of operations of the acquired business are reported as part of the CCM segment. The Accella amounts included in the pro forma financial information below are based on Accella’s historical results and therefore may not be indicative of the actual results if owned by Carlisle. The pro forma adjustments represent management’s best estimates based on information available at the time the pro forma information was prepared and may differ from the adjustments that may actually have been required. Accordingly, pro forma information should not be relied upon as being indicative of the historical results that would have been realized had the acquisition occurred as of the date indicated or that may be achieved in the future. The unaudited combined pro forma financial information presented below includes revenues and income from continuing operations, net of tax, of the Company as if the business combination had occurred on January 1, 2016, based on the purchase price allocation presented below: Unaudited Pro Forma (in millions) 2017 2016 Revenues $ 4,439.4 $ 4,029.8 Income from continuing operations 351.8 235.2 The pro forma financial information reflects adjustments to Accella's historical financial information to apply the Company's accounting policies and to reflect the additional depreciation and amortization related to the fair value adjustments of the acquired net assets of $10.8 million in 2017 and $8.5 million in 2016, together with the associated tax effects. Also, the pro forma financial information reflects costs of goods sold related to the fair valuation of inventory and acquisition-related costs described above as if they occurred in 2016. The following table summarizes the consideration transferred to acquire Accella and the allocation of the purchase price among the assets acquired and liabilities assumed. The acquisition has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations , which requires that consideration be allocated to the acquired assets and assumed liabilities based upon their acquisition date fair values with the remainder allocated to goodwill.

Earnings Per Share [Abstract]
Earnings Per Share	—Earnings Per Share The Company’s restricted shares contain non-forfeitable rights to dividends and are considered participating securities for purposes of computing earnings per share pursuant to the two-class method. The computation below of earnings per share excludes income attributable to the unvested restricted shares from the numerator and excludes the dilutive impact of those underlying share from denominator. The computation below of earnings per share includes the income attributable to the vested and deferred restricted shares and restricted stock units in the numerator and includes the dilutive impact of those underlying shares in the denominator. Stock options are included in the calculation of diluted earnings per share utilizing the treasury stock method and performance share awards are included in the calculation of diluted earnings per share considering those are contingently issuable. Neither is considered to be a participating security as they do not contain non‑forfeitable dividend rights.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer in exchange for payment and is the unit of account. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. The majority of the Company’s contracts have a single performance obligation to transfer individual goods or services. For contracts with multiple performance obligations, the contract's transaction price is allocated to each performance obligation using the Company’s best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is observable prices. The Company’s performance obligations are satisfied, and control is transferred, either at a point in time or over time as work progresses. For the majority of the Company’s products, control is transferred, and revenue is recognized when the product is shipped from the manufacturing facility or delivered to the customer, depending on shipping terms. Revenue is recognized over time primarily for separately priced extended service warranties in the CCM segment and certain highly customized product contracts in the CIT segment. Revenues for separately priced extended service warranties are recognized over the life of the contract. Revenues for highly customized product contracts are recognized based on the proportion of costs incurred to date, relative to total estimated costs to complete the contract and are generally incurred over twelve months or less. Highly customized product contract costs generally include labor, material and overhead. A summary of the timing of revenue recognition and reconciliation of disaggregated revenue by reportable segment follows: 2018 (in millions) CCM CIT CFT CBF Total Products transferred at a point in time $ 2,859.0 $ 900.5 $ 291.6 $ 373.8 $ 4,424.9 Products and services transferred over time 21.3 33.3 — — 54.6 Total revenues $ 2,880.3 $ 933.8 $ 291.6 $ 373.8 $ 4,479.5 Remaining performance obligations for extended service warranties represent the transaction price for the remaining stand-ready obligation to perform warranty services.

Additionally, the Company has applied the transition practical expedient to not disclose the amount of transaction price allocated to the remaining performance obligations and an expectation of when the Company expects to recognize associated revenues, for the year ended December 31, 2018 . Contract Balances Contract liabilities relate to payments received in advance of performance under a contract, primarily related to extended service warranties in the CCM segment and systems contracts in the CFT segment.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	—Stock‑Based Compensation Incentive Compensation Program The Company maintains an Incentive Compensation Program (the “Program”) for executives, certain other employees of the Company and its operating segments and subsidiaries and the Company’s non-employee directors. Members of the Board of Directors (the "Board") that receive stock-based compensation are treated as employees for accounting purposes. The Program was approved by shareholders on May 6, 2015. The Program allows for up to 4.2 million awards to eligible employees of stock options, restricted stock, stock appreciation rights, performance shares and units or other awards based on Company common stock. As of December 31, 2018 , 1.8 million shares were available for grant under this plan. During the year ended December 31, 2018 , the Company awarded 383 thousand stock options as part of the annual equity grant, 621 thousand stock options as part of a one-time grant to all employees, 76 thousand restricted stock awards, 54 thousand performance share awards and 13 thousand restricted stock units with an aggregate grant-date fair value of approximately $40.3 million to be expensed over the requisite service period for each award. Stock-based compensation cost by award type follows: (in millions) 2018 2017 2016 Stock option awards $ 11.0 $ 7.7 $ 6.1 Restricted stock awards 7.7 6.0 4.5 Performance share awards 7.4 5.6 4.7 Restricted stock units 1.4 1.4 1.2 Total stock-based compensation cost $ 27.5 $ 20.7 $ 16.5 In 2018, the Board authorized a grant of stock options to U.S. employees and stock appreciation rights to employees outside of the U.S. This grant contributed $2.7 million to stock-based compensation costs for the year ended December 31, 2018. Compensation cost of $0.5 million was capitalized as inventory and will be recognized in costs of goods sold when that related inventory is sold. The Company recognized an income tax benefit of $10.6 million and $12.5 million related to total stock-based compensation expense for the years ended December 31, 2018 and 2017 , respectively. Stock Option Awards Options issued under the Program generally vest on a straight-line basis over a three -year period on the anniversary date of the grant. All options have a maximum term life of 10 years. Shares issued to cover options under the Program may be issued from shares held in treasury, from new issuances of shares or a combination of the two. Unrecognized compensation cost related to stock options of $14.1 million as of December 31, 2018 , is to be recognized over a weighted-average period of 1.8 years. The Company utilizes the Black‑Scholes-Merton (“BSM”) option pricing model to determine the fair value of its stock option awards. The BSM relies on certain assumptions to estimate an option’s fair value. The weighted average assumptions used in the determination of fair value for stock option awards follows: (in millions, except per share amounts) 2018 One-time Grant 2018 2017 2016 Expected dividend yield 1.4 % 1.4 % 1.3 % 1.4 % Expected life (in years) 3.9 5.5 5.6 5.6 Expected volatility 20.7 % 23.1 % 25.6 % 27.5 % Risk-free interest rate 2.6 % 2.6 % 1.9 % 1.4 % Weighted-average grant date fair value (per share) $ 21.91 $ 23.71 $ 24.57 $ 19.30 Fair value of options granted $ 13.6 $ 9.1 $ 8.8 $ 7.2 The expected life of options is based on the assumption that all outstanding options will be exercised at the midpoint of the valuation date (if vested) or the vesting dates (if unvested) and the options’ expiration date. The expected volatility is based on historical volatility as well as implied volatility of the Company’s options. The risk-free interest rate is based on rates of U.S. Treasury issues with a remaining life equal to the expected life of the option. The expected dividend yield is based on the projected annual dividend payment per share, divided by the stock price at the date of grant. A summary of stock options outstanding and activity follows: Number of Shares (in thousands) Weighted-Average Exercise Price (per share) Weighted-Average Contractual Term (in years) Aggregate Intrinsic Value (in millions) Outstanding as of December 31, 2017 1,431 $ 81.49 Options granted 1,004 107.60 Options exercised (345 ) 65.95 Options forfeited / expired (126 ) 105.86 Outstanding as of December 31, 2018 1,964 95.76 7.7 $ 18.0 Vested and exercisable as of December 31, 2018 844 82.86 6.1 $ 16.4 Additional information related to stock option award activity during the years ended December 31 follows: (in millions) 2018 2017 2016 Intrinsic value of options exercised $ 18.4 $ 8.5 $ 56.4 Fair value of options vested $ 10.2 $ 5.4 $ 4.7 Restricted Stock Awards Restricted stock awarded under the Program is generally released to the recipient after a period of approximately three years. Unrecognized compensation cost related to restricted stock awards of $8.0 million as of December 31, 2018 , is to be recognized over a weighted-average period of 1.6 years. The grant date fair value and intrinsic value of shares vested during the year ended December 31, 2018 was $9.8 million and $11.7 million , respectively. The grant date fair value and intrinsic value of shares vested during the year ended December 31, 2017 was $8.1 million and $11.4 million , respectively. Information related to restricted stock awards during the years ended December 31 follows: 2018 2017 2016 Weighted-average grant date fair value (per share) $ 114.27 $ 106.78 $ 84.73 A summary of restricted stock awards outstanding and activity follows: (in thousands, except per share amounts) Number of Shares Weighted-Average Grant Date Fair Value Outstanding as of December 31, 2017 208 $ 95.63 Shares granted 76 114.27 Shares vested (103 ) 95.05 Shares forfeited (12 ) 109.07 Outstanding as of December 31, 2018 169 103.47 Performance Share Awards Performance shares vest based on the employee rendering three years of service to the Company and the attainment of a market condition over the performance period, which is based on the Company’s relative total shareholder return versus the S&P Midcap 400 Index ® over a pre-determined time period as determined by the Compensation Committee of the Board of Directors. Unrecognized compensation cost related to performance share awards of $5.6 million as of December 31, 2018 , is to be recognized over a weighted-average period of 1.7 years. The grant date fair value and intrinsic value of shares vested during the year ended December 31, 2018 was $5.2 million and $5.3 million , respectively. The grant date fair value and intrinsic value of shares vested during the year ended December 31, 2017 was $10.0 million and $11.6 million , respectively. For purposes of determining diluted earnings per share, the performance share awards are considered contingently issuable shares and are included in diluted earnings per share based upon the number of shares that would have been awarded had the conditions at the end of the reporting period continued until the end of the performance period. See Note 5 for further information regarding earnings per share computations. The Company utilizes the Monte-Carlo simulation approach based on a three-year measurement period to determine the fair value of performance shares. Such approach entails the use of assumptions regarding the future performance of the Company’s stock and those of the S&P Midcap 400 Index ® . Those assumptions include expected volatility, risk‑free interest rates, correlation coefficients and dividend reinvestment. Dividends accrue on the performance shares during the performance period and are to be paid in cash based upon the number of awards ultimately earned. Information related to performance shares during the years ended December 31 follows: 2018 2017 2016 Weighted-average grant date fair value (per share) $ 140.20 $ 141.83 $ 119.08 A summary of performance shares outstanding and activity follows: Number of Shares (in thousands) Weighted-Average Grant Date Fair Value (per share) Weighted-Average Contractual Term (in years) Aggregate Intrinsic Value (in millions) Outstanding as of December 31, 2017 160 $ 123.50 Awards granted 54 140.20 Awards vested (46 ) 112.82 Awards converted (withheld) (9 ) 108.03 Awards forfeited (6 ) 137.55 Outstanding as of December 31, 2018 153 132.68 0.8 $ 15.4 Restricted Stock Units Restricted stock units are awarded to eligible directors and fully vested and are expensed upon grant date. The restricted stock units are paid in shares of Company common stock after the director ceases to serve as a member of the Board, or if earlier, upon a change in control of the Company. The Company granted 13 thousand , 13 thousand and 14 thousand units in 2018 , 2017 and 2016 , respectively. Units had a weighted-average grant date fair value per share of $108.72 , $107.87 and $83.31 in 2018 , 2017 and 2016 , respectively. Restricted stock units' fair value is based on the closing market price of the stock on the respective dates of the grants. Deferred Compensation - Equity Certain employees are eligible to participate in the Company’s Non-qualified Deferred Compensation Plan (the “Deferred Compensation Plan”). Participants may elect to defer all or part of their restricted and performance shares. Participants have elected to defer 202 thousand and 281 thousand shares of Company common stock as of December 31, 2018 and 2017

Restructuring and Related Activities [Abstract]
Exit and Disposal Activities	—Exit and Disposal Activities Beginning in the fourth quarter of 2016, and through 2018, the Company has undertaken operational restructuring and other cost reduction actions to streamline processes and manage costs throughout various departments. These actions resulted in exit, disposal and employee termination benefit costs, primarily resulting from planned reductions in workforce, facility consolidations and relocations and lease termination costs, as further discussed below by operating segment. CBF The Company is nearing completion on its project to exit its manufacturing operations in Tulsa, Oklahoma, and relocate the majority of those operations to its existing manufacturing facility in Medina, Ohio. During 2018, exit and disposal costs totaled $13.6 million , primarily reflecting equipment moving expenses, accelerated depreciation, employee termination benefits and facility closure costs. Total costs are expected to approximate $20.7 million , with cumulative exit and disposal costs of $18.7 million recognized as of December 31, 2018 . The remaining costs will be incurred throughout 2019. CIT The Company is substantially complete with the relocation of certain of its medical manufacturing operations in Shenzhen, China, to a new manufacturing operation in Dongguan, China. During 2018, exit and disposal costs totaled $1.5 million for employee termination benefit costs. The project is substantially complete with cumulative exit and disposal costs recognized of $15.5 million through December 31, 2018 , and total cost expected to approximate $15.6 million . During the third quarter of 2017, the Company entered into a letter of undertaking with the Chinese government, whereby the Company designated $10.1 million in cash specifically for the payment of employee termination benefits associated with the Chinese medical business action discussed above. Cash payments began in August 2017 and were completed in the second quarter of 2018. CFT During 2017, the Company initiated plans to restructure its global footprint. These plans involve exiting manufacturing operations in Brazil and Mexico, exiting the systems sales business in Germany, and relocating the manufacturing operations in Angola, Indiana, to its existing Bournemouth, United Kingdom, manufacturing operations.

The Company believes that it is likely that certain of the state attributes will expire unused and therefore has established a valuation allowance of approximately $1.3 million against the deferred tax assets associated with these attributes. The Company believes that substantially all of the foreign NOLs will be utilized before expiration and therefore has not established a valuation allowance against the deferred tax assets associated with these NOL carryforwards. Undistributed Foreign Earnings As a result of the deemed mandatory repatriation provisions in the Tax Cuts and Jobs Act (the "Tax Act"), the Company included undistributed earnings in income subject to U.S. tax at reduced tax rates in 2017. In addition, the Company recognized in income global intangible low-taxed income (“GILTI”) reduced by foreign tax credits for 2018 as part of the changes from the Tax Act. As a result, the Company does not have material basis differences related to cumulative unremitted earnings for US tax purposes. The Company has determined that an amount approximately equal to foreign cash balances and other certain assets is not permanently reinvested for local country purposes, which results in an accrual of $11.0 million related to foreign withholding taxes. It is not practicable to calculate deferred tax balances on other basis differences. Unrecognized Tax Benefits Unrecognized tax benefits reflect the difference between the tax benefits of positions taken or expected to be taken on income tax returns and the tax benefits that meet the criteria for current recognition in the financial statements. The Company periodically assesses its unrecognized tax benefits. A summary of the movement in gross unrecognized tax benefits (before estimated interest and penalties) follows: (in millions) 2018 2017 2016 Balance as of January 1 $ 37.4 $ 24.6 $ 27.7 Additions based on tax positions related to current year 3.3 3.0 0.6 Additions related to acquired uncertain tax positions — 12.6 — Adjustments for tax positions of prior years — 1.5 — Reductions due to statute of limitations (12.0 ) (3.3 ) (2.1 ) Reductions due to settlements (1.2 ) (1.7 ) (1.4 ) Adjustments due to foreign exchange rates (0.2 ) 0.7 (0.2 ) Balance as of December 31 $ 27.3 $ 37.4 $ 24.6 If the unrecognized tax benefits as of December 31, 2018, were to be recognized, approximately $30.1 million would impact the Company’s effective tax rate. The amount impacting the Company’s effective rate is calculated by adding accrued interest and penalties to the gross unrecognized tax benefit and subtracting the tax benefit associated with state taxes and interest. The Company classifies and reports interest and penalties associated with unrecognized tax benefits as a component of the income tax provision on the Consolidated Statements of Income and as a long‑term liability on the Consolidated Balance Sheets. The total amount of such interest and penalties accrued, but excluded from the table above, at the years ending 2018, 2017 and 2016 were $5.1 million , $5.9 million and $4.7 million , respectively. The Company is subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions. During the year, the Company worked with the IRS to complete its compliance assurance process for the 2017 tax year. The Company is also currently working with the IRS to complete its compliance assurance audit for the 2018 tax year and expects conclusion of the process within the next twelve months. Generally, state income tax returns are subject to examination for a period of three to five years after filing. Substantially all material state tax matters have been concluded for tax years through 2013. Various state income tax returns for subsequent years are in the process of examination. At this stage the outcome is uncertain; however, the Company believes that contingencies have been adequately provided for. Statutes of limitation vary among the foreign jurisdictions in which the Company operates. Substantially all foreign tax matters have been concluded for tax years through 2009. The Company believes that foreign tax contingencies associated with income tax examinations underway or open tax years have been provided for adequately. Based on the outcome of certain examinations or as a result of the expiration of statutes of limitations for certain jurisdictions, the Company believes that within the next 12 months it is reasonably possible that previously unrecognized tax benefits could decrease by approximately $4.0 million to $5.0 million . These previously unrecognized tax benefits relate to a variety of tax issues including tax matters relating to prior acquisitions and various state matters. U.S. Tax Reform On December 22, 2017, the U.S. enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act included significant changes to existing tax law including, among other things, a reduction to the U.S. federal corporate income tax rate from 35% to 21% and a one-time tax on deferred foreign income ("Transition Tax") in 2017. The changes included in the Tax Act are broad and complex. As such, on December 22, 2017, the Securities and Exchange Commission (“SEC”) issued SAB 118. SAB 118 expresses views of the SEC regarding ASC Topic 740, Income Taxes in the reporting period that includes the enactment date of the Tax Act. The SEC staff issuing SAB 118 recognized that a registrant’s review of certain income tax effects of the Tax Act may be incomplete at the time financial statements are issued for the reporting period that includes the enactment date, including interim periods therein. If a company does not have the necessary information available, prepared or analyzed for certain income tax effects of the Tax Act, SAB 118 allows a company to report provisional numbers and adjust those amounts during the measurement period not to extend beyond one year. In the fourth quarter of 2018, the Company completed the accounting for the relevant aspects of the Tax Act based on available information and have recorded a benefit in the year of $3.3 million . While the Tax Act provides for a territorial tax system, beginning in 2018, it includes the GILTI provision. The Company elected to account for GILTI tax in the period in which it is incurred, which is not material in 2018. Deemed Repatriation Transition Tax The deemed repatriation transition tax (the “Transition Tax”) is a tax on certain previously untaxed accumulated and current earnings and profits (“E&P”) of the Company's foreign subsidiaries. The Company was able to reasonably estimate the Transition Tax and recorded an initial provision Transition Tax obligation of $32.5 million for the year ended December 31, 2017. On the basis of revised E&P and taxes paid computation that were calculated during the reporting period, as well as additional guidance provided by taxing authorities, the Company recognized an additional measurement-period beneficial adjustment of $4.6 million to income tax expense during the fourth quarter 2018. The effect of the measurement period adjustment on the 2018 effective tax rate was approximately 1.0% . Reduction of U.S. Federal Corporate Tax Rate The Act reduced the corporate tax rate to 21%, effective January 1, 2018. Consequently, the Company recorded a decrease to the net deferred tax liability in the amount of $90.2 million in the year ended December 31, 2017. In the third quarter of 2018, the Company recorded an additional measurement-period expense of $1.3 million , resulting in a total impact of $88.9 million

As a result, in the third quarter of 2016, the Company recognized impairment charges within its CBF segment of $11.5 million related to the Wellman ® trade name and $130.0 million of goodwill, resulting in a carrying value of $35.4 million and $96.5 million , respectively. Consistent with its accounting policies effective at the date of impairment, the Company performed the impairment tests for these assets through a one-step process for the Wellman ® trade name and a two-step process for goodwill. Wellman ® Trade Name Impairment The Company based its estimate of fair value of the Wellman ® trade name on the income approach utilizing the discounted future cash flow method. As part of estimating discounted future cash flows attributable to the Wellman ® trade name, management estimated future revenues, royalty rates and discount rates. These represent the most significant assumptions used in the Company’s evaluation of the fair value of the Wellman ® trade name (i.e., Level 3 measurements). As a result, management determined that the fair value of the Wellman ® trade name was below its carrying value and recorded an impairment charge equal to the difference as noted above. CBF Goodwill Impairment Similarly, for Step 1 of the two-step goodwill impairment test, the Company estimated the fair value of the CBF reporting unit based on the income approach utilizing the discounted cash flow method. Estimated industry weighted average cost of capital, revenue growth rates and operating margins for the CBF reporting unit represent the most significant assumptions used in the Company’s evaluation of fair value (i.e., Level 3 measurements). As a result, the Company determined that the fair value of the CBF reporting unit was below its carrying value by approximately 25.0% and therefore Step 2 of the goodwill impairment test was required to measure the amount of the Goodwill impairment. In performing the Step 2 analysis, the Company was required to allocate the reporting units’ fair value to the estimated fair values of the CBF reporting unit’s underlying asset and liabilities, both those recognized and unrecognized, with the residual amount reflecting the implied value of goodwill at September 30, 2016.

Retirement Benefits [Abstract]
Retirement Plans	—Retirement Plans Defined Benefit Plans The Company maintains defined benefit retirement plans, primarily for certain domestic employees, as presented below. All plans are frozen to new entrants, with the exception of the executive supplemental plan. Benefits are based primarily on years of service and earnings of the employee. The significant assumptions used in the measurement of the projected benefit obligation and net periodic benefit cost primarily include the discount rate, rate of compensation increase and expected long-term return on plan assets. Weighted‑average assumptions for the projected benefit obligation follows: 2018 2017 Discount rate 4.1 % 3.5 % Rate of compensation increase 3.8 % 3.8 % Weighted‑average assumptions for net periodic benefit cost follows: 2018 2017 2016 Discount rate 3.5 % 3.9 % 4.4 % Rate of compensation increase 3.8 % 3.8 % 4.3 % Expected long-term return on plan assets 6.3 % 6.3 % 6.2 % The weighted-average cash balance interest crediting rate for the Company's cash balance defined benefit plans was 4.0% for the years ended December 31, 2018 and 2017 . The Company considers several factors in determining the long-term rate of return for plan assets. Asset-class return expectations are set using a combination of empirical and forward-looking analyses. Capital market assumptions for the composition of the Company’s asset portfolio are intended to capture the behavior of asset classes observed over several market cycles. The Company also looks to historical returns for reasonableness and appropriateness. A reconciliation of the change in the projected benefit obligation, plan assets and the funded status follows: (in millions) December 31, 2018 December 31, 2017 Funded status Projected benefit obligation Beginning of year $ 182.8 $ 172.5 Change in benefit obligation: Service cost 3.1 2.6 Interest cost 5.5 5.3 Plan amendments — 0.7 Actuarial (gain)/loss (10.0 ) 15.5 Benefits paid (13.9 ) (13.8 ) End of year $ 167.5 $ 182.8 Fair value of plan assets Beginning of year $ 165.7 $ 163.2 Change in plan assets: Actual return on plan assets (4.6 ) 14.9 Company contributions 1.4 1.4 Benefits paid (13.9 ) (13.8 ) End of year $ 148.6 $ 165.7 Unfunded status end of year $ (18.9 ) $ (17.1 ) Accumulated benefit obligation at end of year $ 167.0 $ 181.1 The Company’s projected benefit obligation includes approximately $19.6 million and $22.3 million related to the Company’s executive supplemental and director defined benefit pension plans as of December 31, 2018 and 2017 , respectively. The Company’s accumulated benefit obligation includes approximately $19.1 million and $20.7 million related to the Company’s executive supplemental and director defined benefit pension plans as of December 31, 2018 and 2017 , respectively. The executive supplemental and director defined benefit plans have no plan assets and the Company is not required to fund the obligations. The U.S. plans required to be funded by the Company were fully funded as of December 31, 2018 and 2017 .

The Company employs a liability driven investment approach whereby plan assets are invested primarily in fixed income investments to match the changes in the projected benefit obligation of funded plans related to changes in interest rates. Risk tolerance is established through careful consideration of projected benefit obligations, plan funded status and the Company’s other obligations and strategic investments. The established target allocation is 88.0% fixed income securities and 12.0% equity securities. Fixed income investments are diversified across U.S. treasury, long and intermediate duration and high yield bonds. Equity investments are diversified across large capitalization U.S. and international stocks. Investment risk is measured and monitored on an ongoing basis through investment portfolio reviews, annual projected benefit liability measurements and asset/liability studies.

The Company made contributions of $1.4 million during both 2018 and 2017 , which pertain to the Company’s executive supplemental and director defined benefit pension plans. This contribution covers current participant benefits as these plans have no plan assets. No minimum contributions to the pension plans were required in 2018 and 2017 . During 2019 , the Company expects to pay approximately $1.5 million in participant benefits under the executive supplemental and director plans. In light of the plans’ funded status, the Company does not expect to make discretionary contributions to its pension plans in 2019 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	—Commitments and Contingencies Leases The Company currently leases a portion of its facilities, distribution centers and equipment. Some of the leases include scheduled rent increases stated in the lease agreement, generally expressed as a stated percentage increase of the minimum lease payment over the lease term. The Company currently has no leases that require rent to be paid based on contingent events. Rent expense was $32.1 million , $26.3 million and $23.8 million in 2018 , 2017 and 2016 , respectively, inclusive of rent based on scheduled rent increases and rent holidays recognized on a straight‑line basis. Future minimum payments under its various non‑cancelable operating leases in future years follows: (in millions) 2019 2020 2021 2022 2023 Thereafter Future minimum payments $ 16.7 $ 10.8 $ 6.8 $ 4.9 $ 4.2 $ 5.1 Workers’ Compensation Claims and Related Losses The Company has accrued approximately $19.5 million and $14.9 million (net of $7.0 million of recovery receivables) related to workers’ compensation claims as of December 31, 2018 and 2017 , respectively. As of December 31, 2018 , $4.5 million and $15.0 million were included in accrued expenses and other long‑term liabilities, respectively. As of December 31, 2017 , $4.6 million and $10.3 million were included in accrued expenses and other long‑term liabilities, respectively. The liability related to workers’ compensation claims, both those reported to the Company and those incurred but not yet reported, is estimated based on actuarial estimates, loss development factors and the Company’s historical loss experience. The Company maintains occurrence‑based insurance coverage with certain insurance carriers in accordance with its risk management practices that provides for reimbursement of workers’ compensation claims in excess of $0.5 million . The Company records a recovery receivable from the insurance carriers when such recovery is deemed probable based on the nature of the claim and history of recoveries. As of December 31, 2018 , the Company had a recovery receivable of $6.6 million . The Company's recovery receivables for workers’ compensation claims as of December 31, 2017 , were presented net with the workers' compensation liability, as noted above. Litigation Over the years, the Company has been named as a defendant, along with numerous other defendants, in lawsuits in various state courts in which plaintiffs have alleged injury due to exposure to asbestos‑containing brakes, which Carlisle manufactured in limited amounts between the late‑1940’s and the mid‑1980’s. In addition to compensatory awards, these lawsuits may also seek punitive damages. Generally, the Company has obtained dismissals or settlements of its asbestos‑related lawsuits with no material effect on its financial condition, results of operations, or cash flows. The Company maintains insurance coverage that applies to the Company’s defense costs and payments of settlements or judgments in connection with asbestos‑related lawsuits. At this time, the amount of reasonably possible asbestos claims, if any, is not material to the Company’s financial position, results of operations or operating cash flows, although these matters could result in the Company being subject to monetary damages, costs or expenses and charges against earnings in particular periods. The Company may occasionally be involved in various other legal actions arising in the normal course of business. In the opinion of management, the ultimate outcome of such actions, either individually or in the aggregate, are not expected to have a material adverse effect on the consolidated financial position or annual operating cash flows of the Company. Environmental Matters The Company is subject to increasingly stringent environmental laws and regulations, including those relating to air emissions, wastewater discharges and chemical and hazardous waste management and disposal. Some of these environmental laws hold owners or operators of land or businesses liable for their own and for previous owners' or operators' releases of hazardous or toxic substances or wastes. Other environmental laws and regulations require the obtainment of, and compliance with, environmental permits. To date, costs of complying with environmental, health and safety requirements have not been material, and the Company did not have any significant accruals related to potential future costs of environmental remediation as of December 31, 2018 and 2017 , nor are any asset retirement obligations recorded as of those dates. However, the nature of the Company’s operations and its long history of industrial activities at certain of its current or former facilities, as well as those acquired, could potentially result in material environmental liabilities or asset retirement obligations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	—Financial Instruments Foreign Currency Forward Contracts The Company uses foreign currency forward contracts to hedge a portion of its foreign currency exchange rate exposure to forecasted foreign currency denominated cash flows. These instruments are not held for speculative or trading purposes. A summary of the Company's designated and non-designated cash flow hedges follows: December 31, 2018 December 31, 2017 (in millions) Fair Value (1) Notional Value Fair Value (1) Notional Value Designated hedges $ 0.2 $ 95.0 $ (0.2 ) $ 22.3 Non-designated hedges 0.1 49.9 0.2 38.6 (1) The fair value of foreign currency forward contracts is included in other current assets. The fair value was estimated using observable market inputs such as forward and spot prices of the underlying exchange rate pair. Based on these inputs, derivative assets and liabilities are classified as Level 2 in the fair value hierarchy. For instruments that are designated and qualify as a cash flow hedge, the Company had foreign currency forward contracts with maturities less than one year. The changes in the fair value of the contracts are recorded in accumulated other comprehensive income (loss) and recognized in the same line item as the impact of the hedged item, revenues or cost of sales, when the underlying forecasted transaction impacts earnings. Gains and losses on the contracts representing hedge components excluded from the assessment of hedge effectiveness are recognized in the same line item as the hedged item, revenues or cost of sales, currently. For instruments that are not designed as a cash flow hedge, the Company had foreign exchange contracts with maturities less than one year. The unrealized gains and losses resulting from these contracts were immaterial and are recognized in other non-operating (income) expense, net and partially offset corresponding foreign exchange gains and losses on these balances. Accumulated Other Comprehensive Income (Loss) The changes in accumulated other comprehensive income (loss) by component follows: (in millions) Accrued post-retirement benefit liability Foreign currency translation Foreign currency forward contracts Total Balance as of January 1, 2017 $ (26.4 ) $ (96.7 ) $ 0.9 $ (122.2 ) Other comprehensive income (loss) before reclassifications (11.2 ) 46.6 (4.4 ) 31.0 Amounts reclassified from accumulated other comprehensive income (loss) (1) 2.5 — (0.5 ) 2.0 Income tax benefit 3.5 — — 3.5 Other comprehensive income (loss) (5.2 ) 46.6 (4.9 ) 36.5 Balance as of December 31, 2017 (31.6 ) (50.1 ) (4.0 ) (85.7 ) Adoption of accounting standard (6.5 ) — — (6.5 ) Other comprehensive income (loss): Other comprehensive income (loss) before reclassifications (5.1 ) (30.3 ) 0.4 (35.0 ) Amounts reclassified from accumulated other comprehensive income (loss) (1) 4.6 — 0.4 5.0 Income tax benefit 0.1 — — 0.1 Other comprehensive income (loss) (0.4 ) (30.3 ) 0.8 (29.9 ) Balance as of December 31, 2018 $ (38.5 ) $ (80.4 ) $ (3.2 ) $ (122.1 ) (1) The accrued post‑retirement benefit liability reclassification pertains to the amortization of unrecognized actuarial gains and losses and prior service credits which is included in net periodic benefit cost. See Note 15 for additional pension discussion. Deferred Compensation Rabbi Trust The Company’s Deferred Compensation Plan allows certain eligible participants to defer a portion of their cash compensation and provides a matching contribution to the deferred compensation plan of up to 4.0% of eligible compensation. Eligible compensation may be deferred up to 10 years and distributed via lump sum or annual payment installments over an additional 10 -year period. Participants allocate their deferred compensation amongst various investment options with earnings accruing to the participant. The Company has established a Rabbi Trust to provide for a degree of financial security to cover its obligations with its deferred compensation plan. Contributions to the Rabbi Trust by the Company are made at the discretion of management and generally are made in cash and invested in money-market funds. The Company consolidates the Rabbi Trust and therefore includes the investments in its Consolidated Balance Sheets. As of December 31, 2018 , and 2017 , the Company had $10.7 million and $13.2 million of cash, respectively, and $4.3 million and $4.0 million of short-term investments, respectively. The short-term investments are measured at fair value using quoted market prices in active markets (i.e. Level 1 measurements) with changes in fair value recorded in net income and the associated cash flows presented as operating cash flows. Other Financial Instruments Other financial instruments include cash and cash equivalents, accounts receivable, net, accounts payable, accrued expenses and long-term debt. The carrying value for cash and cash equivalents, accounts receivable, net, accounts payable and accrued expenses approximates fair value because of their short-term nature and generally negligible credit losses (refer to Note 14

Revenue Recognition	Revenue Recognition Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; generally, this occurs with the transfer of control of the Company’s products or services. Revenue is measured as the amount of total consideration expected to be received in exchange for transferring goods or providing services. Total expected consideration, in certain cases, is estimated at each reporting period, including interim periods, and is subject to change with variability dependent on future events, such as customer behavior related to future purchase volumes, returns, early payment discounts and other customer allowances. Estimates for rights of return, discounts and rebates to customers and other adjustments for variable consideration are provided for at the time of sale as a deduction to revenue, based on an analysis of historical experience and actual sales data. Changes in these estimates are reflected as an adjustment to revenue in the period identified. Sales, value added and other taxes collected concurrently with revenue-producing activities are excluded from revenue. The Company receives payment at the inception of the contract for separately priced extended service warranties, and revenue is deferred and recognized on a straight-line basis over the life of the contracts. The term of these warranties ranges from five to 40 years. The weighted average life of the contracts as of December 31, 2018, is approximately 19 years. The Company recognizes revenue over-time for certain contracts that provide for the manufacture of highly-customized products with no alternative use and provide the Company the right to payment for work performed to date, including a normal margin for that effort. Refer to Note 6 for further information on revenue recognition. Costs to Obtain a Contract Costs of obtaining or fulfilling a contract are recognized as expense as incurred, as the amortization period of these costs would be one year or less. These costs generally include sales commissions and are included in selling, general and administrative costs. Shipping and Handling Costs
Other Non-operating (Income) Expense, Net	Other Non-operating (Income) Expense, Net
Stock-Based Compensation	Stock‑Based Compensation The Company accounts for stock‑based compensation under the fair‑value method. Accordingly, equity classified as stock‑based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. The requisite service period generally matches the stated vesting period of the award but may be shorter if the employee is retirement‑eligible and, under the award’s terms, may fully vest upon retirement from the Company. The Company recognizes expense for awards that have graded vesting features under the graded vesting method, which considers each separately vesting tranche as though they were, in substance, multiple awards. Additionally, the Company accounts for forfeitures of stock-based awards as they occur. Refer to Note 7
Income Taxes	Income Taxes Income taxes are recorded in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes
Cash Equivalents	Cash Equivalents Highly liquid investments with a maturity of three months or less when acquired are considered cash equivalents.
Receivables and Allowance for Doubtful Accounts	Receivables and Allowance for Doubtful Accounts Receivables are stated at net realizable value. The Company performs ongoing evaluations of its customers’ current creditworthiness, as determined by the review of their credit information to determine if events have occurred subsequent to the recognition of the revenue and related receivable that provides evidence that such receivable will be realized at an amount less than that recognized at the time of sale. Estimates of net realizable value are based on historical losses, adjusting for current economic conditions and, in some cases, evaluating specific customer accounts for risk of loss. The allowance for doubtful accounts was $5.1 million , $6.5 million and $3.9 million as of December 31, 2018 , 2017 and 2016
Inventories	Inventories
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost including interest costs associated with qualifying capital additions. Costs allocated to property, plant and equipment of acquired companies are based on estimated fair value at the date of acquisition. Depreciation is principally computed on a straight‑line basis over the estimated useful lives of the assets. Asset lives are generally 20 to 40 years for buildings, five to 15 years for machinery and equipment and two to 20
Valuation of Long-Lived Assets	Valuation of Long‑Lived Assets Long‑lived assets or asset groups, including amortizable intangible assets, are tested for impairment whenever events or circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. The Company groups its long‑lived assets classified as held and used at the lowest level for which identifiable cash flows are largely independent of the cash flows from other assets and liabilities for purposes of testing for impairment. The Company’s asset groupings vary based on the related business in which the long‑lived assets are employed and the interrelationship between those long‑lived assets in producing net cash flows; for example, multiple manufacturing facilities may work in concert with one another or may work on a stand‑alone basis to produce net cash flows. The Company utilizes its long‑lived assets in multiple industries and economic environments and its asset groupings reflect these various factors. The Company monitors the operating and cash flow results of its long‑lived assets or asset groups classified as held and used to identify whether events and circumstances indicate the remaining useful lives of those assets should be adjusted or if the carrying value of those assets or asset groups may not be recoverable. Undiscounted estimated future cash flows are compared with the carrying value of the long‑lived asset or asset group in the event indicators of impairment are identified. If the undiscounted estimated future cash flows are less than the carrying amount, the Company determines the fair value of the asset or asset group and records an impairment charge in current earnings to the extent carrying value exceeds fair value. Fair values may be determined based on estimated discounted cash flows by prices for like or similar assets in similar markets or a combination of both.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Intangible assets are recognized and recorded at their acquisition date fair values. Intangible assets that are subject to amortization are amortized on a straight-line basis over their useful lives. Definite-lived intangible assets consist primarily of acquired customer relationships, patents and technology, certain trade names and non-compete agreements. The Company determines the useful life of its definite-lived intangible assets based on multiple factors including the size and make-up of the acquired customer base, the expected dissipation of those customers over time, the Company’s own experience in the particular industry, the impact of known trends such as technological obsolescence, product demand or other factors and the period over which expected cash flows are used to measure the fair value of the intangible asset at acquisition. The Company periodically re-assesses the useful lives of its definite-lived intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Intangible assets with indefinite useful lives are not amortized but are tested annually, or more often if impairment indicators are present, for impairment via a one-step process by comparing the fair value of the intangible asset with its carrying value. If the intangible asset’s carrying value exceeds its fair value, an impairment charge is recorded in current earnings for the excess. The Company estimates the fair value of its indefinite-lived intangible assets based on the income approach utilizing the discounted cash flow method. The Company’s annual testing date for indefinite-lived intangible assets is October 1. The Company periodically re-assesses indefinite-lived intangible assets as to whether their useful lives can be determined and, if so, begins amortizing any applicable intangible asset. Goodwill is not amortized but is tested annually, or more often if impairment indicators are present, for impairment at a reporting unit level. The Company’s annual testing date for goodwill is October 1st. The Company has four
Pension	Pension The Company maintains defined benefit pension plans primarily for certain domestic employees. The annual net periodic benefit cost and projected benefit obligations related to these plans are determined on an actuarial basis annually on December 31, unless a remeasurement event occurs in an interim period. This determination requires assumptions to be made concerning general economic conditions (particularly interest rates), expected return on plan assets, increases to compensation levels and mortality rate trends. Changes in the assumptions to reflect actual experience can result in a change in the net periodic benefit cost and projected benefit obligations. The defined benefit pension plans’ assets are measured at fair value annually on December 31,
Lease Arrangements	Lease Arrangements The Company is a party to various lease arrangements that include scheduled rent increases, rent holidays or may provide for contingent rentals or incentive payments to be made to the Company as part of the terms of the lease. Scheduled rent increases and rent holidays are included in the determination of minimum lease payments when assessing lease classification and, along with any lease incentives, are included in rent expense on a straight‑line basis over the lease term. Scheduled rent increases that are dependent upon a change in an index or rate such as the consumer price index or prime rate are included in the determination of rental expense at the time the rate or index changes. Contingent rentals are excluded from the determination of minimum lease payments when assessing lease classification and are included in the determination of rent expense when the event that will require additional rents is considered probable. Refer to Note 17
Extended Product Warranty Reserves	Extended Product Warranty Reserves
Contingencies and Insurance Recoveries	Contingencies and Insurance Recoveries The Company is exposed to losses related to various potential claims related to its employee obligations and other matters in the normal course of business, including commercial, employee or regulatory litigation. The Company records a liability related to such potential claims, both those reported to the Company and incurred but not yet reported, when probable and reasonably estimable. With respect to workers’ compensation obligations, the Company utilizes actuarial models to estimate the ultimate total cost of such claims, primarily based on historical loss experience and expectations about future costs of providing workers’ compensation benefits.
Derivative Instruments and Hedge Accounting	Derivative Instruments and Hedge Accounting
New Accounting Standards	New Accounting Standards Adopted Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which outlines a single, comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance issued by the FASB, including industry specific guidance. ASU 2014-09 provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts with customers to provide goods and services. In addition to ASU 2014-09, the Company also adopted all the related amendments ("ASC 606") to all uncompleted contracts using the modified retrospective method. The Company recognized the cumulative effect of initially applying ASC 606 as an adjustment to the opening balance of retained earnings totaling $6.5 million . The comparative information has not been adjusted and continues to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of ASC 606 to be immaterial to its reported revenue on an ongoing basis. A majority of the Company's revenues continue to be recognized when products are shipped from its manufacturing facilities or delivered to the customer, depending on shipping terms. For certain highly customized product contracts in the Carlisle Interconnect Technologies segment, revenue was previously recognized as billed, at the point products were shipped and title and associated risk and rewards of ownership passed to the customer. In accordance with ASC 606, the Company now recognizes revenue over time, for those highly customized products, using the input method as products are manufactured. A summary of the effects of adopting ASC 606 on the Consolidated Financial Statements follows: Year Ended December 31, 2018 (in millions) As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Consolidated Statement of Income Revenues $ 4,479.5 $ 4,457.6 $ 21.9 Cost of goods sold 3,304.8 3,290.1 14.7 Operating income 509.0 501.8 7.2 Provision for income taxes 87.3 85.5 1.8 Income from continuing operations 358.6 353.2 5.4 Net income 611.1 605.7 5.4 December 31, 2018 (in millions) As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Consolidated Balance Sheet Receivables $ 698.3 $ 654.0 $ 44.3 Inventories, net 457.5 487.0 (29.5 ) Other current assets 75.3 74.4 0.9 Accrued expenses 258.0 256.2 1.8 Other long-term liabilities 266.5 264.5 2.0 Retained earnings 3,351.4 3,344.9 6.5 Effective January 1, 2018, the Company adopted ASU 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"), which requires employers to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating income, if such measure is presented. The Company adopted ASU 2017-07 using a retrospective approach for the presentation in the Condensed Consolidated Statement of Income. The Company elected to use, as a practical expedient, the amounts disclosed in its defined benefit plan note for the prior comparative period as the estimation basis for applying the retrospective presentation requirements. As a result of adopting ASU 2017-07, net periodic benefit income for the non-service cost components of $(2.4) million was reclassified from other operating (income) expense, net to other non-operating (income) expense, net for the years ended December 31, 2017 and 2016. Effective January 1, 2018, the Company early adopted ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"), which allows entities to reclassify from accumulated other comprehensive income to retained earnings for stranded tax effects related to the change in federal tax rate for all items accounted for in other comprehensive income. Entities can also elect to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act, but do not directly relate to the change in the federal tax rate, including state taxes and changing from a worldwide tax system to a territorial system. Tax effects that are stranded in other comprehensive income for other reasons may not be reclassified. The Company adopted ASU 2018-02 using a modified retrospective approach for the presentation in the Condensed Consolidated Balance Sheets to reclassify $6.5 million related to the change in federal tax rate from accumulated other comprehensive loss to retained earnings. Effective October 1, 2018, the Company early adopted ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic: 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans ("ASU 2018-14"), which makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and other postretirement benefit plans. The guidance requires all sponsors of defined benefit plans to disclose the weighted-average interest crediting rate for cash balance plans and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The guidance also eliminates the required disclosures for the amounts in accumulated other comprehensive income expected to be recognized as components of net period benefit cost over the next fiscal year. The Company adopted ASU 2018-14 using a retrospective approach for the revised disclosure requirements. New Accounting Standards Issued But Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02") which requires lessees to recognize a lease liability for the obligation to make lease payments, measured at the present value on a discounted basis, and a right-of-use ("ROU") asset for the right to use the underlying asset for the duration of the lease term, measured as the lease liability amount adjusted for lease prepayments, lease incentives received, and initial direct costs. The lease liability and ROU asset are recognized in the balance sheet at the commencement of the lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. Classification will be based on criteria that are largely similar to those applied in current lease accounting. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which amended the new leasing standard to give entities another option for transition. This transition option allows entities to not apply the new standard in the comparative periods they present in their financial statements in the year of adoption. ASU 2016-02, and its amendments, are effective for the Company beginning January 1, 2019, and requires the use of a modified retrospective approach for leases that exist at, or are entered into after the beginning of the year of adoption under the new transition guidance. Early application of the ASU is permitted; however, the Company plans to adopt on January 1, 2019 and expects to elect this new transition method. The Company continues its evaluation of adopting the standard, and currently expects the standard to have an impact of approximately $55.0 million to $65.0 million on its assets and liabilities for the addition of ROU assets and lease liabilities. The Company does not expect the standard to have a material impact on its results of operations or liquidity.
