Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies [Text Block]	1. Description of Business and Summary of Significant Accounting Policies Description of Business Dover Corporation ("Dover" or "Company") is a diversified global manufacturer delivering innovative equipment and components, specialty systems, consumable supplies, software and digital solutions and support services. The Company also provides supporting engineering, testing and other similar services, which are not significant in relation to consolidated revenue. The Company’s businesses are based primarily in the United States of America and Europe with manufacturing and other operations throughout the world. The Company operates through three business segments that are aligned with the key end markets they serve: Engineered Systems, Fluids, and Refrigeration & Food Equipment. For additional information on the Company’s segments, see Note 18 — Segment Information. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The results of operations of acquired businesses are included from the dates of acquisitions. As discussed in Note 5 — Discontinued and Disposed Operations, the Company is reporting the assets, liabilities, results of operations and cash flows of Apergy prior to the spin-off, as discontinued operations for all periods presented. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying disclosures. These estimates may be adjusted due to changes in future economic, industry, or customer financial conditions, as well as changes in technology or demand. Estimates are used for, but not limited to, allowances for doubtful accounts receivable, net realizable value of inventories, restructuring reserves, warranty reserves, pension and post-retirement plans, stock-based compensation, useful lives for depreciation and amortization of long-lived assets, future cash flows associated with impairment testing for goodwill, indefinite-lived intangible assets and other long-lived assets, deferred tax assets, uncertain income tax positions and contingencies. Actual results may ultimately differ from estimates, although management does not believe such differences would materially affect the consolidated financial statements in any individual year. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the Consolidated Financial Statements in the period that they are determined. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term investments, which are highly liquid in nature and have original maturities at the time of purchase of three months or less. The carrying value of cash and cash equivalents approximate fair value. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at face amounts less an allowance for doubtful accounts. The allowance is an estimate based on historical collection experience, current economic and market conditions and a review of the current status of each customer's trade accounts receivable. Management evaluates the aging of the accounts receivable balances and the financial condition of its customers to estimate the amount of accounts receivable that may not be collected in the future and records the appropriate provision. Inventories Inventories for the majority of the Company’s subsidiaries, including all international subsidiaries, are stated at the lower of cost, determined on the first-in, first-out (FIFO) basis, or net realizable value. Other domestic inventories are stated at cost, determined on the last-in, first-out (LIFO) basis, which is less than market value. Property, Plant and Equipment Property, plant and equipment includes the historical cost of land, buildings, machinery and equipment, purchased software and significant improvements to existing plant and equipment or, in the case of acquisitions, a fair market value appraisal of assets. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When property or equipment is sold or otherwise disposed of, the related cost and accumulated depreciation is removed from the respective accounts and the gain or loss realized on disposition is reflected in earnings. The Company depreciates its assets on a straight-line basis over their estimated useful lives as follows: buildings and improvements 5 to 31.5 years; machinery and equipment 3 to 7 years; furniture and fixtures 3 to 7 years; vehicles 3 to 7 years; and software 3 to 10 years. Derivative Financial Instruments The Company uses derivative financial instruments to hedge its exposures to various risks, including interest rate and foreign currency exchange rate risk. The Company does not enter into derivative financial instruments for speculative purposes and does not have a material portfolio of derivative financial instruments. Derivative financial instruments used for hedging purposes must be designated and effective as a hedge of the identified risk exposure at inception of the contract. The Company recognizes all derivatives as either assets or liabilities on the consolidated balance sheet and measures those instruments at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair value of both the derivatives and of the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivatives is recorded as a component of other comprehensive earnings and subsequently recognized in net earnings when the hedged items impact earnings. Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over the fair value of net assets acquired. Goodwill and certain other intangible assets deemed to have indefinite lives (primarily trademarks) are not amortized. For goodwill, impairment tests are required at least annually, or more frequently if events or circumstances indicate that it may be impaired, or when some portion but not all of a reporting unit is disposed of or classified as assets held for sale. Based on its current organizational structure, the Company identified seven reporting units for which cash flows are determinable and to which goodwill may be allocated. The Company performs its goodwill impairment test annually in the fourth quarter at the reporting unit level. A quantitative test is used to determine existence of goodwill impairment and the amount of the impairment loss at the reporting unit level. The quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill. The Company uses an income-based valuation method, determining the present value of estimated future cash flows, to estimate the fair value of a reporting unit. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Factors used in the impairment analysis require significant judgment, and actual results may differ from assumed and estimated amounts. The Company uses its own market assumptions including internal projections of future cash flows, discount rates and other assumptions considered reasonable and inherent in the analysis. These forecasts are based on historical performance and future estimated results. The discount rates used in these analyses vary by reporting unit and are based on a capital asset pricing model and published relevant industry rates. The Company uses discount rates commensurate with the risks and uncertainties inherent to each reporting unit and in the internally developed forecasts. See Note 8 — Goodwill and Other Intangible Assets for further discussion of the Company's annual goodwill impairment test and results. The Company uses an income-based valuation method to annually test its indefinite-lived intangible assets for impairment. The fair value of the intangible asset is compared to its carrying value. This method uses the Company’s own market assumptions, which are considered reasonable and inherent in the analysis. Any excess of carrying value over the estimated fair value is recognized as an impairment loss. No impairment of indefinite-lived intangible assets was required for the years ended December 31, 2018, 2017, or 2016. Other intangible assets with determinable lives primarily consist of customer intangibles, unpatented technologies, patents and trademarks. The other intangible assets are amortized over their estimated useful lives, ranging from 5 to 15 years. Long-lived assets (including definite-lived intangible assets) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, such as a significant sustained change in the business climate. If an indicator of impairment exists for any grouping of assets, an estimate of undiscounted future cash flows is produced and compared to its carrying value. If an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value, as determined by an estimate of discounted future cash flows. Restructuring Accruals From time to time, the Company takes actions to reduce headcount, close facilities, or otherwise exit operations. Such restructuring activities at an operation are recorded when management has committed to an exit or reorganization plan and when termination benefits are probable and can be reasonably estimated based on circumstances at the time the restructuring plan is approved by management or when termination benefits are communicated. Exit costs include future minimum lease payments on vacated facilities and other contractual terminations. In addition, asset impairments may be recorded as a result of an approved restructuring plan. The accrual of both severance and exit costs requires the use of estimates. Though the Company believes that its estimates accurately reflect the anticipated costs, actual results may be different from the original estimated amounts. Foreign Currency Assets and liabilities of non-U.S. subsidiaries, where the functional currency is not the U.S. dollar, have been translated at year-end exchange rates and profit and loss accounts have been translated using weighted-average monthly exchange rates. Foreign currency translation gains and losses are included in the Consolidated Statements of Comprehensive Earnings as a component of other comprehensive earnings (loss). Assets and liabilities of an entity that are denominated in currencies other than an entity’s functional currency are re-measured into the functional currency using end of period exchange rates or historical rates, where applicable to certain balances. Gains and losses related to these re-measurements are recorded within the Consolidated Statements of Earnings as a component of other expense (income), net. Gains and losses arising from intercompany foreign currency transactions that are of a long-term investment in nature are reported in the same manner as translation adjustments. Revenue Recognition Effective January 1, 2018, the Company adopted Accounting Standard Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606” or “ASC 606”). Under Topic 606, a contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance and where payment terms are identified and collectability is probable. Once the Company has entered a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as discounts and volume rebates. Prior to 2018, revenue is recognized when all the following conditions are satisfied: a) persuasive evidence of an arrangement exists, b) price is fixed or determinable, c) collectability is reasonably assured and d) delivery has occurred or services have been rendered. The majority of the Company’s revenue is generated through the manufacture and sale of a broad range of specialized products and components, with revenue recognized upon transfer of control, title and risk of loss, which is generally upon shipment. Service revenue represents less than 5% of total revenue and is recognized as the services are performed. In limited cases, revenue arrangements with customers require delivery, installation, testing, certification, or other acceptance provisions to be satisfied before revenue is recognized. The Company includes shipping costs billed to customers in revenue and the related shipping costs in cost of goods and services. Stock-Based Compensation The principal awards issued under the Company’s stock-based compensation plans include non-qualified stock appreciation rights ("SARs"), restricted stock units and performance share awards. The cost for such awards is measured at the grant date based on the fair value of the award. At the time of grant, the Company estimates forfeitures, based on historical experience, in order to estimate the portion of the award that will ultimately vest. The value of the portion of the award that is expected to ultimately vest is recognized as expense on a straight-line basis, generally over the explicit service period of three years (except for retirement-eligible employees and retirees) and is included in selling, general and administrative expenses in the Consolidated Statements of Earnings. Expense for awards granted to retirement-eligible employees is recorded over the period from the date of grant through the date the employee first becomes eligible to retire and is no longer required to provide service. See Note 14 — Equity and Cash Incentive Program for additional information related to the Company’s stock-based compensation. Income Taxes The provision for income taxes includes federal, state, local and non-U.S. taxes. Tax credits, primarily for research and experimentation, are recognized as a reduction of the provision for income taxes in the year in which they are available for tax purposes. Deferred taxes are provided using enacted rates on the future tax consequences of temporary differences. Temporary differences include the differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis and the tax benefit of carryforwards. A valuation allowance is established for deferred tax assets for which realization is not assured. In assessing the need for a valuation allowance, management considers all available evidence, including the future reversal of existing taxable temporary differences, taxable income in carryback periods, prudent and feasible tax planning strategies and estimated future taxable income. The valuation allowance can be affected by changes to tax regulations, interpretations and rulings, changes to enacted statutory tax rates and changes to future taxable income estimates. Tax benefits are recognized from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position in consideration of applicable tax statutes and related interpretations and precedents. Tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized on ultimate settlement. On December 22, 2017, the U.S. bill commonly referred to as the Tax Cuts and Jobs Act (“Tax Reform Act”) was enacted, which significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a one-time repatriation tax on deemed repatriated earnings of foreign subsidiaries. The Tax Reform Act reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. The Tax Reform Act also provided for a one-time deemed repatriation of post-1986 undistributed foreign subsidiary earnings and profits (“E&P”) through the year ended December 31, 2017. The Global Intangible Low-Taxed Income ("GILTI") provisions of the Tax Reform Act require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company is subject to incremental U.S. tax on GILTI income due to expense allocations required by the U.S. foreign tax credit rules. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company recognized the provisional tax impacts related to deemed repatriated earnings and the benefit for the revaluation of deferred tax assets and liabilities, and included these amounts in its consolidated financial statements for the year ended December 31, 2017. In accordance with SAB 118, the Company finalized the financial reporting impact of the Tax Reform Act in the fourth quarter of 2018. For the year ended December 31, 2018, the Company recorded a $4.2 million net tax benefit, which resulted in a 0.6% decrease in the effective tax rate, as an adjustment to provisional estimates as a result of additional regulatory guidance and changes in interpretations and assumptions the Company has made as a result of the Tax Reform Act. Research and Development Costs Research and development costs, including qualifying engineering costs, are expensed when incurred and amounted to $143,033 in 2018, $130,536 in 2017 and $115,840 in 2016. These costs as a percent of revenue were 2.0% in 2018 and 1.9% in 2017 and 2016. Revisions were made to the 2017 and 2016 research and development costs and impacted only the disclosure as the costs were appropriately included in the Consolidated Statement of Earnings. The revisions were not material to the prior annual periods. Advertising Costs Advertising costs are expensed when incurred and amounted to $26,831 in 2018, $33,369 in 2017 and $35,035 in 2016. Risk, Retention, Insurance The Company currently self-insures its product and commercial general liability claims up to $5.0 million per occurrence, its workers’ compensation claims up to $0.8 million per occurrence and automobile liability claims up to $5.0 million per occurrence. Third-party insurance provides primary level coverage in excess of these amounts up to certain specified limits. In addition, the Company has excess liability insurance from third-party insurers on both an aggregate and an individual occurrence basis well in excess of the limits of the primary coverage. A worldwide program of property insurance covers the Company’s owned and leased property and any business interruptions that may occur due to an insured hazard affecting those properties, subject to reasonable deductibles and aggregate limits. The Company’s property and casualty insurance programs contain various deductibles that, based on the Company’s experience, are typical and customary for a company of its size and risk profile. The Company does not consider any of the deductibles to represent a material risk to the Company. The Company generally maintains deductibles for claims and liabilities related primarily to workers’ compensation, health and welfare claims, general commercial, product and automobile liability, cybersecurity risks, property damage and business interruption resulting from certain events. The Company accrues for claim exposures that are probable of occurrence and can be reasonably estimated. As part of the Company’s risk management program, insurance is maintained to transfer risk beyond the level of self-retention and provide protection on both an individual claim and annual aggregate basis. Reclassifications – Certain amounts in prior years have been reclassified to conform to the current year presentation. Recent Accounting Pronouncements Recently Issued Accounting Standards The following standards, issued by the Financial Accounting Standards Board ("FASB"), will, or are expected to, result in a change in practice and/or have a financial impact to the Company’s Consolidated Financial Statements: In August 2018, the FASB issued Accounting Standards Update ("ASU") 2018-15, Intangibles-Goodwill and Other Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for interim and annual periods for the Company beginning on January 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is in the process of assessing the impact of this ASU on its Consolidated Financial Statements but does not expect this update to have a material impact on the Company's Consolidated Financial Statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU provides new guidance about income statement classification and eliminates the requirement to separately measure and report hedge ineffectiveness. The entire change in fair value for qualifying hedge instruments included in the effectiveness will be recorded in other comprehensive income (OCI) and amounts deferred in OCI will be reclassified to earnings in the same income statement line item in which the earnings effect of the hedged item is reported. The guidance is effective for interim and annual periods for the Company on January 1, 2019, with early adoption permitted. The Company does not expect the adoption of this ASU to have a material impact on its Consolidated Financial Statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The guidance is effective for interim and annual periods for the Company on January 1, 2020, with early adoption permitted. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. Currently, the Company believes that the most notable impact of this ASU may relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on trade accounts receivable and the recognition of credit losses. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which amended existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. This ASU also provides clarifications surrounding the presentation of the effects of leases in the income statement and statement of cash flows. This guidance was effective for the Company on January 1, 2019. In addition, the FASB issued ASU 2018-11, Leases Targeted Improvements which provides an additional transition method that allows entities to apply the new leases standard at adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. The Company elected this new transition method when it adopted ASU 2016-02 on January 1, 2019. During the second half of 2017, the Company developed a project plan to guide the implementation of ASU 2016-02. The Company completed this plan including surveying the Company’s businesses, assessing the Company’s portfolio of leases and compiling a central repository of active leases. The Company also implemented a lease accounting software solution to support the new reporting requirements and established a future lease process to keep the lease accounting portfolio up to date. The Company evaluated key policy elections and considerations under the standard and completed an internal policy as well as training to address the new standard requirements. The Company plans to elect the package of practical expedients and will not apply the recognition requirements to short-term leases. Although management continues to evaluate the effect to the Company's Consolidated Balance Sheets and disclosures, management currently estimates total assets and liabilities will increase approximately $150 million to $200 million upon adoption, before considering deferred taxes. Management does not expect a material impact to the Company’s Consolidated Statements of Earnings or Cash Flows. Recently Adopted Accounting Standards In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740) Amendments to SEC Paragraphs Pursuant to the SEC Staff Accounting Bulletin No. 118 ("SAB 118"). This ASU provides guidance on income tax accounting implications under the Tax Reform Act. SAB 118 addressed the application of GAAP to situations when a registrant does not have the necessary information available, prepared and analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act and allows companies to record provisional amounts during the re-measurement period not to exceed one year after the enactment date while the accounting impact remains under analysis. This guidance was effective immediately upon issuance. See Note 13 — Income Taxes for further details. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU allows for the reclassification from Accumulated Other Comprehensive Income ("AOCI") to retained earnings for tax effects resulting from the Tax Reform Act that are stranded in AOCI. ASU 2018-02, however, does not change the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. The Company early adopted this guidance on January 1, 2018, and elected to reclassify the stranded tax effects from AOCI to retained earnings of $12.9 million. The stranded tax effects were specifically identified and represented the difference between the change in the amount of income tax from 35% to 21%, recognized in AOCI primarily for the deferred taxes associated with pensions, which were recognized in the Consolidated Statement of Earnings for the year ended December 31, 2017. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU changes the income statement presentation of defined benefit and post-retirement benefit plan expense by requiring separation between operating expense (service cost component of net periodic benefit expense) and non-operating expense (all other components of net periodic benefit expense, including interest cost, amortization of prior service cost, curtailments and settlements, etc.). The operating expense component is reported with similar compensation costs while the non-operating components are reported outside of operating income. The non-operating components are reported in the other (income) expense, net line item in the Consolidated Statement of Earnings. The Company’s non-operating cost components of net periodic cost were a benefit (cost) of $5.8 million, $8.6 million and $(2.4) million during the years ended December 31, 2018 and 2017 and 2016 respectively. The impact of this adoption resulted in a reclassification to the Company’s Condensed Consolidated Statement of Earnings for the year ended December 31, 2017 and 2016 in which previously reported selling, general and administrative expenses were adjusted by $8.6 million and $(2.4) million, respectively, with a corresponding adjustment to other income, net. The Company utilized a practical expedient included in the ASU which allowed the Company to use amounts previously disclosed in its pension and other post-retirement benefits note for the prior period as the estimation basis for applying the required retrospective presentation requirements. The Company adopted this guidance on January 1, 2018. In January 2017, the FASB issued ASU 2017-01, Business combinations (Topic 805): Clarifying the definition of a business, which clarifies the definition of a business and assists entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under this guidance, when substantially all of the fair value of gross assets acquired is concentrated in a single asset (or group of similar assets), the assets acquired would not represent a business. In addition, in order to be considered a business, an acquisition would have to include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The amended guidance also narrows the definition of outputs by more closely aligning it with how outputs are described in FASB guidance for revenue recognition. The Company adopted this guidance on January 1, 2018. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The Company adopted this guidance on January 1, 2018. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements.

Spin-off of Apergy Corporation

Spin-off of Apergy Corporation	12 Months Ended

Planned Spin-Off [Abstract]
Spin-off of Apergy Corporation[Text Block]	2. Spin-off of Apergy Corporation On May 9, 2018, Dover completed the distribution of Apergy to its shareholders. The transaction was completed through the pro rata distribution of 100% of the common stock of Apergy to Dover's shareholders of record as of the close of business on April 30, 2018. Each Dover shareholder received one share of Apergy common stock for every two shares of Dover common stock held as of the record date. The following is a summary of the assets and liabilities transferred to Apergy as part of the separation on May 9, 2018: Assets: Cash and cash equivalents $ 10,357 Current assets 462,620 Non-current assets 1,438,760 $ 1,911,737 Liabilities: Current liabilities $ 185,354 Non-current liabilities 119,568 $ 304,922 Net assets distributed to Apergy Corporation $ 1,606,815 Less: Cash received from Apergy Corporation 700,000 Net distribution to Apergy Corporation $ 906,815 In connection with the spin-off from the Company, Apergy issued and sold $300.0 million in aggregate principal amount of its 6.375% senior notes due May 2026 in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended, and incurred $415.0 million in borrowings under its new senior secured term loan facility to fund a one-time cash payment of $700.0 million to Dover. Dover received net cash of $689.6 million upon separation, which reflects $10.4 million of cash held by Apergy on the distribution date and retained by it in connection with its separation from Dover. Dover utilized the proceeds from Apergy as the primary source of funding for $1 billion of share repurchases started in December 2017. See Note 20 — Stockholders' Equity for further information. Included within the net assets distributed to Apergy is approximately $33 million of accumulated other comprehensive earnings attributable to Apergy, relating primarily to foreign currency translation gains, offset by unrecognized losses on pension obligations. The historical results of Apergy, including the results of operations, cash flows, and related assets and liabilities have been reclassified to discontinued operations for all periods presented herein. See Note 5 — Discontinued and Disposed Operations. Pursuant to the separation of Apergy from Dover, and the related separation and distribution agreements, any liabilities due from Dover to Apergy are not significant and will be paid in the near future.

Revenue

Revenue	12 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	3. Revenue Revenue from contracts with customers Effective January 1, 2018, the Company adopted Accounting Standard Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606” or “ASC 606”), using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Accordingly, all periods prior to January 1, 2018 are presented in accordance with ASC Topic 605, Revenue Recognition ("Topic 605” or “ASC 605”). Under Topic 606, a contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance and where payment terms are identified and collectability is probable. Once the Company has entered a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as discounts and volume rebates. A majority of the Company’s revenue is short cycle in nature with shipments within one year from order. A small portion of the Company’s revenue derives from contracts extending over one year. The Company's payment terms generally range between 30 to 90 days and vary by the location of businesses, the type of products manufactured to be sold and the volume of products sold, among other factors. Disaggregation of Revenue Revenue from contracts with customers is disaggregated by end markets, segments and geographic location, as it best depicts the nature and amount of the Company’s revenue. The following table presents revenue disaggregated by end market and segment: Year Ended December 31, 2018 Printing & Identification $ 1,162,431 Industrials 1,580,517 Total Engineered Systems segment 2,742,948 Fueling & Transport 1,465,590 Pumps 676,027 Process Solutions 655,721 Total Fluids segment 2,797,338 Refrigeration 1,197,072 Food Equipment 256,021 Total Refrigeration & Food Equipment segment 1,453,093 Intra-segment eliminations (1,261) Total Consolidated Revenue $ 6,992,118 The following table presents revenue disaggregated by geography based on the location of the Company's customer: Year Ended December 31, 2018 United States $ 3,619,717 Europe 1,572,788 Asia 867,268 Other Americas 631,164 Other 301,181 Total $ 6,992,118 The majority of revenue from our Engineered Systems, Fluids and Refrigeration and Food Equipment segments is generated from sales to customers within the United States and Europe. Each segment also generates revenue across the other geographies, with no significant concentration of any segment’s remaining revenue. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service, or a bundle of goods or services, to the customer, and is the unit of accounting under ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. A majority of the Company’s contracts have a single performance obligation which represents, in most cases, the equipment or product being sold to the customer. Some contracts include multiple performance obligations such as a product and the related installation, extended warranty and/or maintenance services. These contracts require judgment in determining the number of performance obligations. The Company has elected to use the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component if it is expected, at contract inception, that the period between when Dover transfers a promised good or service to a customer, and when the customer pays for that good or service, will be one year or less. Thus, the Company may not consider an advance payment to be a significant financing component, if it is received less than one year before product completion. The majority of the Company’s contracts offer assurance-type warranties in connection with the sale of a product to a customer. Assurance-type warranties provide a customer with assurance that the related product will function as the parties intended because it complies with agreed-upon specifications. Such warranties do not represent a separate performance obligation. The Company may also offer service-type warranties that provide services to the customer, in addition to the assurance that the product complies with agreed-upon specifications. If a warranty is determined to be a service-type warranty, it represents a distinct service and is treated as a separate performance obligation. For contracts with multiple performance obligations, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. The Company uses an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available. Over 95% of the Company’s performance obligations are recognized at a point in time that relate to the manufacture and sale of a broad range of products and components. Revenue is recognized when control transfers to the customer upon shipment or completion of installation, testing, certification, or other substantive acceptance provisions required under the contract. Less than 5% of the Company’s revenue is recognized over time and relates to the sale of engineered to order equipment or services. For revenue recognized over time, there are two types of methods for measuring progress and both are relevant to the Company: (1) input methods and (2) output methods. Although this may vary by business, input methods generally are based on costs incurred relative to estimated total costs. Output methods generally are based on a measurement of progress, such as milestone achievement. The businesses use the method and measure of progress that best depicts the transfer of control to the customer of the goods or services to date relative to the remaining goods or services promised under the contract. Transaction Price Allocated to the Remaining Performance Obligations At December 31, 2018, we estimated that $83.8 million in revenue is expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. We expect to recognize approximately 56% of our unsatisfied (or partially unsatisfied) performance obligations as revenue in 2019, with the remaining balance to be recognized in 2020 and thereafter. Remaining consideration, including variable consideration, from contracts with customers is included in the amounts presented above and primarily consists of extended warranties on products and multi-year maintenance agreements, which are typically recognized as the performance obligation is satisfied. The Company applied the standard's practical expedient that permits the omission of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which the Company has the right to invoice for services performed. Contract Balances The following table provides information about contract assets and contract liabilities from contracts with customers: 12/31/2018 At Adoption Contract assets $ 9,330 $ 11,932 Contract liabilities - current 36,461 48,268 Contract liabilities - non-current 9,382 9,916 Contract assets primarily relate to the Company's right to consideration for work completed but not billed at the reporting date and are recorded in prepaid and other current assets in the Condensed Consolidated Balance Sheet. Contract assets are transferred to receivables when the right to consideration becomes unconditional. Contract liabilities relate to advance consideration received from customers for which revenue has not been recognized. Current contract liabilities are recorded in other accrued expenses and non-current contract liabilities are recorded in other liabilities in the Condensed Consolidated Balance Sheet. Contract liabilities are reduced when the associated revenue from the contract is recognized. Significant changes in contract assets and liabilities balances during the period are as follows: Contract Assets Opening balance at January 1, 2018 $ 11,932 Cumulative catch-up adjustment upon transition 701 Changes in the estimate of the stage of completion 11,884 Transferred to receivables from contract assets recognized during the period (14,947) Other (240) Closing balance at December 31, 2018 $ 9,330 Contract Liabilities Opening balance at January 1, 2018 $ 58,184 Revenue recognized during the period (68,211) Increases due to cash received 64,603 Other (8,733) Closing balance at December 31, 2018 $ 45,843 The revenue recognized during 2018 that was included in the contract liability at the beginning of the period amounted to $38,410. Contract Costs Costs incurred to obtain a customer contract are not material to the Company. The Company elected to apply the practical expedient to not capitalize contract costs to obtain contracts with a duration of one year or less, which are expensed and included within cost of goods and services in the Condensed Consolidated Statements of Earnings. Critical Accounting Estimates Estimates are used to determine the amount of variable consideration in contracts, the standalone selling price among separate performance obligations and the measure of progress for contracts where revenue is recognized over time. The Company reviews and updates these estimates regularly. Some contracts with customers include variable consideration primarily related to volume rebates. The Company estimates variable consideration at the most likely amount to determine the total consideration which the Company expects to be entitled. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available. Changes in Accounting Policies The Company adopted Topic 606, effective January 1, 2018, using the modified retrospective method applying Topic 606 to contracts that are not complete as of the date of initial application. Under the modified retrospective method, the cumulative effect of applying the standard has been recognized at the date of initial application, January 1, 2018. The comparative information has not been adjusted and continues to be reported under Topic 605. The Company's accounting policy has been updated to align with Topic 606, and no significant changes to revenue recognition have occurred as a result of the change. Shipping and handling charges are not considered a separate performance obligation. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities must be accrued. Additionally, all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer (e.g., sales, use, value added, and some excise taxes) are excluded from revenue. The Company's policy elections related to shipping and handling and taxes have not changed with the adoption of Topic 606. Under Topic 605, revenue was generally recognized when all of the following criteria were met: a) persuasive evidence of an arrangement exists, b) price is fixed or determinable, c) collectability is reasonably assured and d) delivery has occurred or services have been rendered. The majority of the Company's revenue is generated through the manufacture and sale of a broad range of specialized products and components and revenue was recognized upon transfer of title and risk of loss, which was generally upon shipment. In limited cases, the Company's revenue arrangements with customers required delivery, installation, testing, certification, or other acceptance provisions to be satisfied before revenue was recognized. The Company included shipping costs billed to customers in Revenue and the related shipping costs in Cost of goods and services. Impact on Financial Statements The adoption of Topic 606 impacted certain contracts for highly customized customer products that have no alternative use and in which the contract specifies the Company has a right to payment for its costs, plus a reasonable margin. For these contracts, the Company now recognizes revenue over time based on the method and measure of progress that best depicts the transfer of control to the customer of the goods or services to date relative to the remaining goods or services promised under the contract. The Company recorded a cumulative catch-up adjustment to retained earnings at January 1, 2018 for $0.2 million, related to the impact of adopting Topic 606 under the modified retrospective method. The impact of adopting Topic 606 was not material to the Company’s consolidated financial statements for the year ended December 31, 2018.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions 2018 During the year ended December 31, 2018, the Company acquired two businesses in separate transactions for total consideration of $68,557, net of cash acquired. The businesses were acquired to complement and expand upon existing operations within the Fluids and Refrigeration & Food Equipment segments. The goodwill identified by these acquisitions reflects the benefits expected to be derived from product line expansion and operational synergies. The goodwill is non-deductible for U.S. federal income tax purposes for these acquisitions. On January 2, 2018, the Company acquired 100% of the voting stock of Ettlinger Group ("Ettlinger"), within the Fluids segment for $53,218, net of cash acquired. In connection with this acquisition, the Company recorded goodwill of $36,303 and intangible assets of $19,907, primarily related to customer intangibles. The intangible assets are being amortized over 8 to 15 years. On January 12, 2018, the Company acquired 100% of the voting stock of Rosario Handel B.V. ("Rosario"), within the Refrigeration & Food Equipment segment for total consideration of $15,339, net of cash acquired. In connection with this acquisition, the Company recorded goodwill of $10,408 and a customer intangible asset of $4,149. The customer intangible asset is being amortized over 10 years. The pro forma effects of these acquisitions on the Company’s operations are disclosed in this footnote. 2017 During the year ended December 31, 2017, the Company acquired two businesses in separate transactions for total consideration of $34,300. On April 5, 2017, the Company purchased 100% of the voting stock of Caldera Graphics S.A.S. ("Caldera") within the Engineered Systems segment for $32,857, net of cash acquired and including contingent consideration. In connection with this acquisition, the Company recorded goodwill of $27,174 and intangible assets of $8,169, primarily related to customer intangibles. The goodwill is non-deductible for U.S. federal income tax purposes. The intangible assets are being amortized over 7 to 15 years. One other immaterial acquisition was completed during the year within the Engineered Systems segment. The pro forma effects of these acquisitions on the Company’s operations are disclosed in this footnote. 2016 During 2016, the Company acquired six businesses, in separate transactions, for total consideration of $1,561,737, net of cash acquired. During the measurement period, the Company recorded working capital adjustments which resulted in final net cash consideration of $1,554,448. These acquisitions were completed primarily to complement and expand upon existing operations within the Fluids and Engineered Systems segments. Pro Forma Information The following unaudited pro forma results of operations reflect the 2018 acquisitions as if they had occurred on January 1, 2017 and the 2017 acquisitions as if they had occurred on January 1, 2016. The pro forma information is not necessarily indicative of the results that actually would have occurred, nor does it indicate future operating results. The supplemental pro forma earnings reflect adjustments to earnings from continuing operations as reported in the Consolidated Statements of Earnings to exclude nonrecurring expense related to the fair value adjustments to acquisition-date inventory (after-tax) and acquisition-related costs (after-tax) from the year ended December 31, 2018. These adjustments were not material in 2018 and 2017. The supplemental pro forma earnings for the 2017 period were similarly adjusted for 2017 acquisitions charges as if incurred at the beginning of 2016. The 2018 and 2017 supplemental pro forma earnings are also adjusted to reflect the comparable impact of additional depreciation and amortization expense, net of tax, resulting from the fair value measurement of tangible and intangible assets relating to 2018 and 2017 acquisitions.

Discontinued Operations and Disposal Groups [Abstract]
Disposed and Discontinued Operations	5. Discontinued and Disposed Operations Discontinued Operations The Apergy businesses, as discussed in Note 2, met the criteria to be reported as discontinued operations because the spin-off is a strategic shift in business that has a major effect on the Company's operations and financial results. Therefore, the results of discontinued operations for the years ended December 31, 2018, 2017 and 2016 include the historical results of Apergy prior to its distribution on May 9, 2018. The years ended December 31, 2018, 2017 and 2016 included costs incurred by Dover to complete the spin-off of Apergy amounting to $46,384, $15,270 and $0, respectively, reflected in selling, general and administrative expenses in discontinued operations. Due to lump-sum payments made in 2018 for Apergy participants of the Dover U.S. Pension Plan, non-cash settlement and curtailment costs of approximately $9,200 was classified within discontinuing operations. See Note 2 — Spin-off of Apergy Corporation and Note 16 — Employee Benefit Plans for further information. Summarized results of the Company's discontinued operations are as follows: Years Ended December 31, 2018 2017 2016 Revenue $ 403,688 1,010,135 $ 751,808 Cost of goods and services 254,205 648,805 507,392 Gross profit 149,483 361,330 244,416 Selling, general and administrative expenses 147,261 262,353 236,510 Operating earnings 2,222 98,977 7,906 Other expense, net 9,048 949 3,218 (Loss) earnings from discontinued operations before taxes (6,826) 98,028 4,688 Provision (benefit) for income taxes 14,052 33,026 (2,076) (Loss) earnings from discontinued operations, net of tax $ (20,878) 65,002 $ 6,764 Assets and liabilities of discontinued operations are summarized below: December 31, 2017 Assets of Discontinued Operations Accounts receivable $ 202,052 Inventories, net 201,591 Prepaid and other current assets 14,035 Total current assets 417,678 Property, plant and equipment, net 211,832 Goodwill and intangible assets, net 1,232,843 Other assets and deferred charges 3,200 Total assets $ 1,865,553 Liabilities of Discontinued Operations Accounts payable $ 97,439 Other current liabilities 59,482 Total current liabilities 156,921 Deferred income taxes 90,641 Other liabilities 16,691 Total liabilities $ 264,253 On May 9, 2018, all assets and liabilities of Apergy were spun-off. Therefore, as of December 31, 2018, there were no assets and liabilities classified as discontinued operations. Disposed Businesses 2018 There were no other material dispositions in 2018 aside from the spin-off of Apergy. 2017 On November 1, 2017, the Company completed the sale of the consumer and industrial winch business of Warn Industries, Inc. ("Warn"), a wholly owned subsidiary of the Company, for total consideration of $250,283. The Company recognized a pre-tax gain on sale of $116,932. The Company retained the automotive business of Warn within the Industrials platform of the Engineered Systems segment. On February 14, 2017, the Company completed the sale of Performance Motorsports International ("PMI"), a wholly owned subsidiary of the Company that manufactures pistons and other engine related components serving the motorsports and powersports markets. Total consideration for the transaction was $147,313, including cash proceeds of $118,706. The Company recognized a pre-tax gain on sale of $88,402 and recorded a 25% equity method investment at fair value of $18,607 as well as a subordinated note receivable of $10,000. Other immaterial dispositions completed during the year were recorded as a net pre-tax loss of $2,196. Gains and losses recorded from the sale of businesses were reported in the gain on sale of businesses line in the Consolidated Statements of Earnings. 2016 On February 17, 2016, the Company completed the sale of Texas Hydraulics, a custom manufacturer of fluid power components within the Engineered Systems segment. The Company received gross proceeds of $47,300 and in connection with the sale of Texas Hydraulics, the Company recorded a pre-tax gain of $11,853. On November 1, 2016, the Company completed the sale of Tipper Tie, a global supplier of processing and clip packaging machines within the Refrigeration & Food Equipment segment. The Company received gross proceeds of $158,887 with the sale and recorded a pre-tax gain of $85,035. Management evaluates Dover's businesses periodically and may from time to time sell or discontinue certain operations for various reasons. The disposals in 2017 and 2016 did not represent strategic shifts in operations and, therefore, did not qualify for presentation as a discontinued operation, unless otherwise noted.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	8. Goodwill and Other Intangible Assets Goodwill ASC 350 “Intangibles - Goodwill and Other Intangibles” provides guidance on an entity's subsequent measurement and recognition of goodwill and other intangibles, including subsequent changes to carrying amounts, including impairment and fair value adjustments. In accordance with the guidance set forth in ASC 350, and in connection with the separation of Apergy, the Company was required to calculate the portion of goodwill included in the Apergy distribution. Using a relative fair value approach, the Company reallocated $3,546 of goodwill from a reporting unit that included Apergy to a reporting unit now included within the Engineered Systems segment. See Note 18 — Segment Information for further information. The changes in the carrying value of goodwill by reportable operating segments were as follows: Engineered Systems Fluids Refrigeration & Food Equipment Total Goodwill $ 1,636,291 $ 1,563,938 $ 536,179 $ 3,736,408 Accumulated impairment loss (10,591) (59,970) — (70,561) Balance at January 1, 2017 $ 1,625,700 $ 1,503,968 $ 536,179 $ 3,665,847 Acquisitions 30,180 — — 30,180 Purchase price adjustments 6,826 (35,939) — (29,113) Disposition of business (79,113) — (296) (79,409) Foreign currency translation 61,796 36,255 816 98,867 Balance at December 31, 2017 1,645,389 1,504,284 536,699 3,686,372 Reallocation due to Apergy separation 3,546 — — 3,546 Acquisitions — 36,303 10,408 46,711 Purchase price adjustments 328 — — 328 Foreign currency translation (25,603) (32,985) (1041) (59,629) Balance at December 31, 2018 $ 1,623,660 $ 1,507,602 $ 546,066 $ 3,677,328 During 2018 and 2017, the Company recognized additions of $46,711 and $30,180, respectively, to goodwill as a result of acquisitions as discussed in Note 4 — Acquisitions. During 2018 and 2017, the Company recorded adjustments totaling $328 and $(29,113), respectively, as a result of the finalization of purchase price allocation to assets acquired and liabilities assumed related to acquisitions completed in 2017 and 2016. The net goodwill transferred to Apergy on May 9, 2018 amounted to $899,888. During 2017, the Company derecognized $79,409 of goodwill as a result of the disposition of businesses as discussed in Note 5 — Discontinued and Disposed Operations. The Company reallocated goodwill upon disposal based upon the fair value of the disposed business relative to the remaining entities in its reporting unit. Annual impairment testing The Company tests goodwill for impairment annually in the fourth quarter of each year and whenever events or circumstances indicate an impairment may have occurred. Consequently, in connection with the separation of Apergy, the Company realigned its remaining businesses and reallocated goodwill among its reporting units based on their relative fair value and tested goodwill for impairment in the second quarter of 2018. The Company concluded that no impairment indicators existed. The Company performed its annual goodwill impairment test during the fourth quarter of 2018 using a discounted cash flow analysis as discussed in Note 1 — Description of Business and Summary of Significant Accounting Policies. The Company performed a quantitative goodwill impairment test for each of its seven reporting units, concluding that the fair values of all of its reporting units were substantially in excess of their carrying values. As previously noted, the fair values of each of the Company’s reporting units was determined using a discounted cash flow analysis which includes management’s current assumptions as to future cash flows and long-term growth rates. The discount rates used in these analyses varied by reporting unit and were based on a capital asset pricing model and published relevant industry rates. The Company used discount rates commensurate with the risks and uncertainties inherent to each reporting unit and in our internally developed forecasts. Discount rates used in the 2018 reporting unit valuations ranged from 8.5% to 9.5%. While the Company believes the assumptions used in the 2018 impairment analysis are reasonable and representative of expected results, if market conditions worsen or persist for an extended period of time, an impairment of goodwill or assets may occur. The Company will continue to monitor the long-term outlook and forecasts, including estimated future cash flows, for these businesses and the impact on the carrying value of goodwill and assets.

Restructuring expense includes $56,138 related to two significant rightsizing programs for the year ended December 31, 2018. Rightsizing during the first half of the year were largely initiated in the fourth quarter of 2017 and designed to better align the Company's cost structure in preparation for the Apergy separation and included targeted facility consolidations, headcount reductions and other measures to further optimize operations. The rightsizing actions taken due to the Apergy separation are substantially complete. Rightsizing in the second half of 2018 were comprised primarily of broad-based selling, general and administrative expense reduction and footprint consolidation initiatives designed to increase operating margin, enhance operations and position the Company for sustained growth and investment. The Company expects to incur total charges of approximately $42 million related to selling, general and administrative expense reduction initiatives, $37 million of which was incurred during the year ended December 31, 2018 and approximately $5 million of which the Company expects to incur in 2019. The Company expects to incur total restructuring charges of approximately $15 million related to the footprint consolidation initiatives, $5 million of which was incurred during the year ended December 31, 2018 and approximately $10 million of which the Company expects to incur in 2019 and 2020. Additional programs, beyond the scope of the announced programs may be implemented during 2019 with related restructuring charges. The $58.5 million of restructuring charges incurred during 2018 included the following programs: • The Engineered Systems segment recorded $21,040 of restructuring charges related to programs across the segment focused on headcount reductions and manufacturing plant consolidation. • The Fluids segment recorded $25,744 of restructuring charges principally related to headcount reductions and manufacturing plant and facility consolidations, focused on achieving long-term footprint optimization. • The Refrigeration & Food Equipment segment recorded $3,475, of restructuring charges primarily due to headcount reductions, product exit and manufacturing plant consolidation. • Corporate recorded $8,244 of restructuring charges primarily related to headcount reductions. Restructuring expenses incurred in 2017 and 2016 also included headcount reduction, targeted facility consolidations at certain businesses and actions taken to optimize the Company's cost structure.

Financial Instruments Derivatives The Company is exposed to market risk for changes in foreign currency exchange rates due to the global nature of its operations. In order to manage this risk the Company has hedged portions of its forecasted sales and purchases, which occur within the next twelve months and are denominated in non-functional currencies, with currency forward contracts designated as cash flow hedges. At December 31, 2018 and 2017, the Company had contracts with U.S. dollar equivalent notional amounts of $153,873 and $115,580, respectively, to exchange foreign currencies, principally the Pound Sterling, Chinese yuan, Swedish krona, Euro, and Canadian dollar. The Company believes it is probable that all forecasted cash flow transactions will occur. In addition, the Company had outstanding contracts at December 31, 2018 and 2017 with a total notional amount of $66,906 and $59,952, respectively, that are not designated as hedging instruments. These instruments are used to reduce the Company's exposure to operating receivables and payables that are denominated in non-functional currencies. Gains and losses on these contracts are recorded in other expense (income), net in the Consolidated Statements of Earnings. The following table sets forth the fair values of derivative instruments held by the Company as of December 31, 2018 and 2017 and the balance sheet lines in which they are recorded: Fair Value Asset (Liability) December 31, 2018 December 31, 2017 Balance Sheet Caption Foreign currency forward $ 1,874 $ 358 Prepaid/Other assets Foreign currency forward (1,165) (2,243) Other accrued expenses For a cash flow hedge, the effective portion of the change in estimated fair value of a hedging instrument is recorded in Other comprehensive earnings (loss), net of tax as a separate component of the Consolidated Statements of Stockholders' Equity and is reclassified into Cost of goods and services in the Consolidated Statements of Earnings during the period in which the hedged transaction is recognized. The amount of gains or losses from hedging activity recorded in earnings is not significant and the amount of unrealized gains and losses from cash flow hedges, which are expected to be reclassified to earnings in the next twelve months, is not significant; therefore, additional tabular disclosures are not presented. There are no amounts excluded from the assessment of hedge effectiveness and the Company's derivative instruments that are subject to credit risk contingent features were not significant. The Company is exposed to credit loss in the event of nonperformance by counterparties to the financial instrument contracts held by the Company; however, nonperformance by these counterparties is considered unlikely as the Company’s policy is to contract with highly-rated, diversified counterparties. The Company has designated the €300,000 and €600,000 of euro-denominated notes issued December 4, 2013 and November 9, 2016, respectively, as a hedge of a portion of its net investment in euro-denominated operations. Changes in the value of the euro-denominated debt are recognized in foreign currency translation adjustments within other comprehensive earnings (loss) of the Consolidated Statements of Comprehensive Earnings to offset changes in the value of the net investment in euro-denominated operations. Changes in the value of the euro-denominated debt resulting from exchange rate differences are offset by changes in the net investment due to the high degree of effectiveness between the hedging instruments and the exposure being hedged. Amounts recognized in other comprehensive earnings (loss) for the gains (losses) on its net investment hedges were as follows: 2018 2017 2016 Gain/(loss) on euro-denominated debt $ 45,230 $ (125,262) $ 53,791 Tax (expense)/benefit (9,498) 43,842 (18,827) Gain/(loss) on net investment hedges, net of tax $ 35,732 $ (81,420) $ 34,964 Fair Value Measurements Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. ASC 820 establishes three levels of inputs that may be used to measure fair value as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company's assets and liabilities measured at fair value on a recurring basis as of December 31, 2018 and 2017 were as follows: Level 2 Level 2 Assets: Foreign currency cash flow hedges $ 1,874 $ 358 Liabilities: Foreign currency cash flow hedges 1,165 2,243 The derivative contracts are measured at fair value using models based on observable market inputs such as foreign currency exchange rates and interest rates; therefore, they are classified within Level 2 of the fair value hierarchy. In addition to fair value disclosure requirements related to financial instruments carried at fair value, accounting standards require disclosures regarding the fair value of all of the Company’s financial instruments. The estimated fair value of long-term debt at December 31, 2018 and 2017 was $3,132,330 and $3,324,776, respectively, compared to the carrying value of $2,943,660 and $2,986,702, respectively. The estimated fair value of long-term debt is based on quoted market prices for similar instruments and is, therefore, classified as Level 2 within the fair value hierarchy. The carrying values of cash equivalents, trade receivables, accounts payable and notes payable are reasonable estimates of their fair values as of December 31, 2018 and 2017 due to the short-term nature of these instruments.

The entire balance of the non-U.S. losses as of December 31, 2018 is available to be carried forward, with $150.6 million of these losses beginning to expire during the years 2019 through 2038. The remaining $897.5 million of such losses can be carried forward indefinitely. The Company has $62.9 million and $59.8 million of state tax loss carryforwards as of December 31, 2018 and 2017, respectively that are available for use by the Company between 2019 and 2038. The Company maintains valuation allowances by jurisdiction against the deferred tax assets related to certain of these carryforwards as utilization of these tax benefits is not assured for certain jurisdictions. On December 22, 2017, the Tax Reform Act was enacted which permanently reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. As a result of the reduction in the U.S. corporate income tax rate, the Company revalued its ending net deferred tax liabilities as of December 31, 2017 and recognized a provisional tax benefit of $172.0 million. The Tax Reform Act also imposed a tax for a one-time deemed repatriation of post-1986 unremitted foreign earning and profit through the year ended December 31, 2018. As of December 31, 2017, the Company recorded provisional tax expense related to the deemed repatriation of $111.6 million payable over eight years. The GILTI provisions of the Tax Reform Act require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. On December 22, 2017, the SEC staff issued SAB 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. In accordance with the SAB 118 guidance, the Company recognized the provisional tax impacts related to deemed repatriated earnings and the benefit for the revaluation of deferred tax assets and liabilities in its consolidated financial statements for the year ended December 31, 2017. In accordance with SAB 118, the Company finalized the financial reporting impact of the Tax Reform Act in the fourth quarter of 2018. For the year ended December 31, 2018, the Company recorded a $4.2 million net tax benefit, which resulted in a 0.6% decrease in the effective tax rate, as an adjustment to the provisional estimates as a result of additional regulatory guidance and changes in interpretations and assumptions the Company has made as a result of the Tax Reform Act. Unrecognized Tax Benefits The Company files U.S. federal, state, local and foreign tax returns. The Company is routinely audited by the tax authorities in these jurisdictions, and a number of audits are currently underway. It is reasonably possible during the next twelve months that uncertain tax positions may be settled, which could result in a decrease in the gross amount of unrecognized tax benefits. This decrease may result in an income tax benefit. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, the Company's gross unrecognized tax benefits balance may change within the next twelve months by a range of zero to $12.5 million. The Company is no longer subject to examinations of its federal income tax returns through 2014. All significant state, local and international matters have been concluded through 2012. The Company believes adequate provision has been made for all income tax uncertainties. The following table is a reconciliation of the beginning and ending balances of the Company’s unrecognized tax benefits: Total Unrecognized tax benefits at January 1, 2016 $ 66,088 Additions based on tax positions related to the current year 7,929 Additions for tax positions of prior years 9,076 Reductions for tax positions of prior years (3,067) Cash settlements (3,106) Lapse of statutes (6,605) Unrecognized tax benefits at December 31, 2016 70,315 Additions based on tax positions related to the current year 14,466 Additions for tax positions of prior years 4,105 Reductions for tax positions of prior years (9,653) Cash settlements (954) Lapse of statutes (10,245) Unrecognized tax benefits at December 31, 2017 68,034 Additions based on tax positions related to the current year 15,580 Additions for tax positions of prior years 29,637 Reductions for tax positions of prior years (5,226) Cash settlements (7,345) Lapse of statutes (7,219) Unrecognized tax benefits at December 31, 2018 ( 1 ) $ 93,461 ( 1 ) If recognized, the net amount of potential tax benefits that would impact the Company’s effective tax rate is $85.4 million. During the years ended December 31, 2018, 2017 and 2016, the Company recorded expense (income) of $2.4 million, $(0.5) million and $0.7 million, respectively, as a component of provision for income taxes related to the accrued interest and penalties on unrecognized tax benefits. The Company had accrued interest and penalties of $18.8 million at December 31, 2018 and $16.5 million at December 31, 2017, which are not included in the above table.

Share-based Compensation [Abstract]
Share-based Compensation [Abstract]	14. Equity and Cash Incentive Program The Company's share-based awards are typically granted annually at its regularly scheduled first quarter Compensation Committee meeting. Additionally, in the second quarter, the Company granted equity awards to its new President and Chief Executive Officer. Awards made pursuant to the terms of the Company's 2012 Equity and Cash Incentive Plan (the "2012 Plan"), which was approved by shareholders on May 3, 2012. This plan replaced the 2005 Equity and Cash Incentive Plan (the "2005 Plan"), which would have otherwise terminated according to its terms on January 31, 2015 and the 1996 Non-Employee Directors Stock Compensation Plan (the "Directors Plan"), which would have otherwise terminated according to its terms on December 31, 2012. Upon adoption of the 2012 Plan, no additional awards could be granted under the 2005 Plan. Officers and other key employees, as well as non-employee directors, are eligible to participate in the 2012 Plan, which has a ten-year term and will terminate on May 3, 2022. The 2012 Plan provides for stock options and SARs grants, restricted stock awards, restricted stock unit awards, performance share awards, cash performance awards, directors' shares and deferred stock units. Under the 2012 Plan, a total of 17,000,000 shares of common stock are reserved for issuance, subject to adjustments resulting from stock dividends, stock splits, recapitalizations, reorganizations and other similar changes. The exercise price per share for SARs is equal to the closing price of the Company’s stock on the New York Stock Exchange on the date of grant. New common shares are issued when SARs are exercised. The period during which SARs are exercisable is fixed by the Company’s Compensation Committee at the time of grant. Generally, the SARs vest after three ten In addition, in connection with the separation of Apergy, the Company modified the outstanding equity awards for its employees. The awards were modified such that all individuals received an equivalent fair value both before and after the separation of Apergy. This modification resulted in the issuance of an additional 1,138,008 SARs, 26,316 performance shares, and 47,063 RSUs. The exercise price of these outstanding awards, where applicable, was adjusted to preserve the value of the awards immediately prior to the separation. As no incremental fair value was awarded as a result of the issuance of these additional shares, the modification did not result in additional compensation expense. Stock-based compensation costs are reported within Selling, general and administrative expenses in the Consolidated Statements of Earnings. The following table summarizes the Company’s compensation expense relating to all stock-based incentive plans: Years Ended December 31, 2018 2017 2016 Pre-tax stock-based compensation expense (continuing) $ 23,698 $ 24,073 $ 18,650 Tax benefit (2,722) (8,411) (6,579) Total stock-based compensation expense, net of tax $ 20,976 $ 15,662 $ 12,071 Pre-tax stock-based compensation expense attributable to Apergy employees for the year ended December 31, 2018, 2017 and 2016 was $744, $2,454 and $2,366, respectively. These costs are reported within earnings from discontinued operations in the Condensed Consolidated Statement of Earnings. On January 1, 2017, the Company adopted ASU 2016-09, Compensation: Stock Compensation (Topic 718). The adoption of the new standard resulted in the recognition of excess tax benefits in the Company's provision for income taxes within the Consolidated Statements of Earnings rather than paid-in capital of $14,759 and $8,365 for the years ended December 31, 2018 and 2017, respectively. The Company recognized a net tax benefit of $4,964 during 2016 for the exercise of SARs, restricted stock awards, restricted stock unit awards and performance share awards. These benefits for 2016 have been recorded as an increase to additional paid-in capital and are reflected as financing cash inflows in the Consolidated Statements of Cash Flows. SARs In 2018, 2017 and 2016, the Company issued SARs covering 757,603, 1,028,116 and 1,346,354 shares, respectively. Since 2006, the Company has only issued SARs and does not anticipate issuing stock options in the future. The fair value of each SAR grant was estimated on the date of grant using a Black-Scholes option-pricing model with the following assumptions: 2018 2017 2016 Risk-free interest rate 2.58 % - 2.87% 1.80 % 1.05 % Dividend yield 1.99 % - 2.43% 2.27 % 3.09 % Expected life (years) 5.6 - 5.7 4.6 4.6 Volatility 20.95 % - 21.20% 21.90 % 26.17 % Grant price (1) $79.75 - $82.09 $ 66.85 $ 48.28 Fair value at date of grant (1) $14.58 - $15.41 $ 10.65 $ 7.80 (1) Updated to reflect the modification of grants in connection with the separation of Apergy on May 9, 2018. Expected volatilities are based on Dover's stock price history, including implied volatilities from traded options on Dover stock. The Company uses historical data to estimate SAR exercise and employee termination patterns within the valuation model. The expected life of SARs granted is derived from the output of the option valuation model and represents the average period of time that SARs granted are expected to be outstanding. The interest rate for periods within the contractual life of the awards is based on the U.S. Treasury yield curve in effect at the time of grant. A summary of activity relating to SARs granted under the 2012 Plan and the predecessor plans for the year ended December 31, 2018 is as follows: SARs Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Outstanding at January 1, 2018 6,573,979 $ 62.78 Granted ( 1 ) 757,603 81.43 Surrendered upon spin-off ( 2 ) (210,119) 68.36 Modification upon spin-off ( 3 ) 1,138,008 — Forfeited / expired (438,014) 68.76 Exercised (2,492,253) 47.17 Outstanding at December 31, 2018 5,329,204 60.19 6.2 Exercisable at December 31, 2018 2,661,980 $ 57.26 4.5 (1) Weighted average grant-date fair value updated to reflect the modification of grants in connection with the separation of Apergy on May 9, 2018. ( 2 ) In connection with the spin-off on May 9, 2018, Apergy employees surrendered their outstanding Dover equity awards, which were then converted to Apergy equity awards. ( 3 ) Subsequent to the separation of Apergy, the Company modified its outstanding equity awards to employees such that all individuals received an equivalent fair value both before and after the separation, which resulted in a lower exercise price for all outstanding equity awards at the time of modification. The following table summarizes information about outstanding SARs at December 31, 2018: SARs Outstanding SARs Exercisable Range of Exercise Prices Number of Shares Weighted Average Exercise Price Weighted Average Remaining Life in Years Aggregate Intrinsic Value Number of Shares Weighted Average Exercise Price Weighted Average Remaining Life in Years Aggregate Intrinsic Value $21.89 - $37.79 135,497 $ 29.61 0.9 $ 5,601 135,497 $ 29.61 0.9 $ 5,601 $40.54 - $58.69 2,323,949 $ 50.13 5.3 48,394 1,233,688 $ 31.87 3.6 23,646 $61.79 - $82.51 2,869,758 $ 69.79 7.3 10,881 1,292,795 $ 65.33 5.7 7,368 5,329,204 $ 64,876 2,661,980 $ 36,615 Unrecognized compensation expense related to SARs not yet exercisable was $8,315 at December 31, 2018. This cost is expected to be recognized over a weighted average period of 1.8 years. Other information regarding the exercise of SARs is listed below: 2018 2017 2016 SARs Fair value of SARs that became exercisable $ 12,832 $ 16,006 $ 24,843 Aggregate intrinsic value of SARs exercised $ 101,365 $ 44,646 $ 34,916 Performance Share Awards Performance share awards granted are expensed over the three-year requisite performance and service period. Awards become vested if (1) the Company achieves certain specified internal metrics and (2) the employee remains continuously employed by the Company during the performance period. Partial vesting may occur after separation from service in the case of certain terminations not for cause and for retirements. In 2018, 2017 and 2016, the Company issued performance shares covering 122,459, 57,958 and 79,561 shares, respectively. The performance share awards granted in these years are considered performance condition awards as attainment is based on Dover's performance relative to established internal metrics. The fair value of these awards was determined using Dover's closing stock price on the date of grant. The expected attainment of the internal metrics for these awards is analyzed each reporting period, and the related expense is adjusted up or down based on expected attainment, if that attainment differs from previous estimates. The cumulative effect on current and prior periods of a change in attainment is recognized in Selling, general and administrative expenses in the Consolidated Statements of Earnings in the period of change. The fair value and average attainment used in determining compensation cost of the performance shares issued in 2018, 2017 and 2016 are as follows for the year ended December 31, 2018: Performance shares 2018 2017 2016 Fair value per share at date of grant (1) $79.75 - $82.09 $66.85 $48.28 Average attainment rate reflected in expense 285.39 % 280.00 % 34.61 % (1) Updated to reflect the modification of grants in connection with the separation of Apergy on May 9, 2018. A summary of activity for performance share awards for the year ended December 31, 2018 is as follows: Number of Shares Weighted Average Grant-Date Fair Value Unvested at January 1, 2018 124,467 $ 65.80 Granted (1) 122,459 80.30 Surrendered upon spin-off ( 2 ) (10,683) 67.39 Modification upon spin-off ( 3 ) 26,316 — Forfeited (57,015) 67.88 Vested (60,587) 48.27 Unvested at December 31, 2018 144,957 $ 76.99 (1) Weighted average grant-date fair value updated to reflect the modification of grants in connection with the separation of Apergy on May 9, 2018. ( 2 ) In connection with the spin-off on May 9, 2018, Apergy employees surrendered their outstanding Dover equity awards, which were then converted to Apergy equity awards. ( 3 ) Subsequent to the separation of Apergy, the Company modified its outstanding equity awards to employees such that all individuals received an equivalent fair value both before and after the separation. Unrecognized compensation expense related to unvested performance shares as of December 31, 2018 was $21,603, which will be recognized over a weighted average period of 1.9 years. Restricted Stock Units The Company also has restricted stock authorized for grant (as part of the 2012 Plan). Under this Plan, common stock of the Company may be granted at no cost to certain officers and key employees. In general, restrictions limit the sale or transfer of these shares during a three-year period, and restrictions lapse proportionately over the three-year period. The Company granted 284,721, 174,203 and 249,263 of restricted stock units in 2018, 2017 and 2016, respectively. The fair value of these awards was determined using Dover's closing stock price on the date of grant. A summary of activity for restricted stock units for the year ended December 31, 2018 is as follows: Number of Shares Weighted Average Grant-Date Fair Value Unvested at January 1, 2018 333,886 $ 70.06 Granted (1) 284,721 80.59 Surrendered upon spin-off ( 2 ) (26,762) 70.21 Modification upon spin-off ( 3 ) 47,063 — Forfeited (58,436) 69.66 Vested (189,991) 70.06 Unvested at December 31, 2018 390,481 $ 73.35 (1) Weighted average grant-date fair value updated to reflect the modification of grants in connection with the separation of Apergy on May 9, 2018. ( 2 ) In connection with the spin-off on May 9, 2018, Apergy employees surrendered their outstanding Dover equity awards, which were then converted to Apergy equity awards. ( 3 ) Subsequent to the separation of Apergy, the Company modified its outstanding equity awards to employees such that all individuals received an equivalent fair value both before and after the separation. Unrecognized compensation expense relating to unvested restricted stock units as of December 31, 2018 was $18,987, which will be recognized over a weighted average period of 1.9 years. Directors' Shares The Company issued the following shares to its non-employee directors under the 2012 Plan as partial compensation for serving as directors of the Company: Years ended December 31, 2018 2017 2016 Aggregate shares granted 15,802 16,231 21,023 Shares deferred (9,917) (11,337) (11,882) Net shares issued 5,885 4,894 9,141

Commitments and Contingent Liabilities	15. Commitments and Contingent Liabilities Lease Commitments The Company leases certain facilities and equipment under operating leases, many of which contain renewal options. Total rental expense, net of insignificant sublease rental income, for all operating leases was $78,674, $76,177 and $69,393 for the years ended December 31, 2018, 2017 and 2016, respectively. Contingent rentals under the operating leases were not significant. The aggregate future minimum lease payments for operating and capital leases as of December 31, 2018 are as follows: Operating Capital 2019 $ 49,009 $ 1,802 2020 38,620 1,748 2021 29,396 1,687 2022 21,767 1,392 2023 13,994 4,754 Thereafter 42,087 — Total $ 194,873 $ 11,383 Guarantees The Company has provided typical indemnities in connection with sales of certain businesses and assets, including representations and warranties and related indemnities for environmental, health and safety, tax and employment matters. The Company does not have any material liabilities recorded for these indemnifications and is not aware of any claims or other information that would give rise to material payments under such indemnities. Product Recall During the fourth quarter of 2016, the Company determined that there was a quality issue with a product component part in the Fluids segment and voluntarily reported this issue to the U.S. Consumer Product Safety Commission (“CPSC”). The Company recorded warranty expense of $23,150 in costs of goods and services in the Consolidated Statement of Earnings for the year ended December 31, 2016. During the first quarter of 2017, the Company announced a voluntary recall of the product in collaboration with the CPSC. The warranty accrual was $497 and $6,613 in other accrued expenses in the Consolidated Balance Sheets at December 31, 2018 and 2017, respectively. Litigation A few of the Company’s subsidiaries are involved in legal proceedings relating to the cleanup of waste disposal sites identified under federal and state statutes which provide for the allocation of such costs among “potentially responsible parties.” In each instance, the extent of the Company’s liability appears to be relatively insignificant in relation to the total projected expenditures and the number of other “potentially responsible parties” involved and is anticipated to be immaterial to the Company. In addition, a few of the Company’s subsidiaries are involved in ongoing remedial activities at certain current and former plant sites, in cooperation with regulatory agencies, and appropriate reserves have been established.

Defined Benefit Plan [Abstract]
Employee Benefit Plans	16. Employee Benefit Plans The Company offers defined contribution retirement plans which cover the majority of its U.S. employees, as well as employees in certain other countries. The Company’s expense relating to defined contribution plans was $46,030, $43,447 and $37,065 for the years ended December 31, 2018, 2017 and 2016, respectively. Revisions were made to the 2017 and 2016 defined contribution expenses and impacted only the disclosure as the costs were appropriately included in the Consolidated Statement of Earnings. The revisions were not material to the prior annual periods. The Company sponsors qualified defined benefit pension plans covering certain employees of the Company and its subsidiaries. The plans’ benefits are generally based on years of service and employee compensation. The Company also provides to certain management employees, through non-qualified plans, supplemental retirement benefits in excess of qualified plan limits imposed by federal tax law. In July 2013, the Company announced that, after December 31, 2013, the U.S. qualified and non-qualified defined benefit plans would be closed to new employees. All pension-eligible employees as of December 31, 2013 will continue to earn a pension benefit through December 31, 2023 as long as they remain employed by an operating company participating in the impacted plans. The Company also announced that effective January 1, 2024, the plans would be frozen to any future benefit accruals. In connection with the spin-off, assets and liabilities related to the Norris USW participants were moved to a new plan sponsored by Apergy. Assets and liabilities of several non-U.S. qualified and U.S. non-qualified plans were also transferred to Apergy. Apergy participants (other than Norris USW participants) in the Dover U.S. pension plan (the "Plan") fully vested in their benefits and ceased accruing future benefits. The separation of Apergy triggered a pension plan curtailment which required a re-measurement of the Plan's benefit obligation in the second quarter, assuming a discount rate of 4.2% and an expected return on assets of 6.8%. The Plan retained the obligation and participants were able to elect lump-sum payments from plan assets. In 2018, the Plan made total lump sum payments of $74,016. Based on the total lump sum payments made to both Apergy and other participants in the plan during the year and the second quarter re-measurement, the Company recorded non-cash settlement and curtailment charges of approximately $13,939 in 2018, of which $9,200 was classified within discontinued operations. The Company also maintains other post-retirement benefit plans which cover approximately 409 participants, approximately 386 of whom are eligible for medical benefits. These plans are closed to new entrants. The supplemental and other post-retirement benefit plans are supported by the general assets of the Company. Obligations and Funded Status The following tables summarize the Consolidated Balance Sheets impact, including the benefit obligations, assets and funded status associated with the Company's significant defined benefit and other post-retirement benefit plans at December 31, 2018 and 2017.

The majority of the international obligations relate to defined pension plans operated by the Company’s businesses in Germany, the United Kingdom and Switzerland. The accumulated benefit obligation for all defined benefit pension plans was $756,194 and $908,656 at December 31, 2018 and 2017, respectively. Pension plans with accumulated benefit obligations in excess of plan assets consist of the following at December 31, 2018 and 2017: 2018 2017 Projected benefit obligation (PBO) $ 330,168 $ 372,559 Accumulated benefit obligation (ABO) 311,192 349,735 Fair value of plan assets 154,673 162,890 Net Periodic Benefit Cost Components of the net periodic benefit cost were as follows: Defined Benefit Plans Qualified Defined Benefits Non-Qualified Supplemental Benefits U.S. Plan Non-U.S. Plans 2018 2017 2016 2018 2017 2016 2018 2017 2016 Service cost $ 9,019 $ 12,083 $ 13,913 $ 5,359 $ 5,688 $ 5,590 $ 2,624 $ 2,473 $ 2,959 Interest cost 20,756 21,718 23,046 4,962 5,263 5,593 3,204 4,076 5,268 Expected return on plan assets (39,045) (39,812) (38,793) (7,675) (7,417) (7,830) — — — Amortization of: Prior service cost (credit) 298 427 733 (449) (425) (397) 3,770 4,411 6,266 Recognized actuarial loss (gain) 3,102 5,582 6,437 2,952 3,506 2,658 (1,132) (1,192) (560) Transition obligation — — — 1 4 4 — — — Settlement and curtailment loss (gain) 13,939 ( 1 ) 76 — 7 678 1,103 (1,381) — — Other — — 35 — — — — — — Net periodic benefit expense $ 8,069 $ 74 $ 5,371 $ 5,157 $ 7,297 $ 6,721 $ 7,085 $ 9,768 $ 13,933 Less: Discontinued operations 10,109 ( 1 ) 3,383 4,237 114 810 974 279 1,226 1,222 Net periodic (income) expense - Continuing operations $ (2,040) $ (3,309) $ 1,134 $ 5,043 $ 6,487 $ 5,747 $ 6,806 $ 8,542 $ 12,711 (1) $9.2 million of the total settlement and curtailment loss on the U.S. Plan is attributable to Apergy participants in the Dover Defined Benefit Plan and has therefore, been reflected in the results of discontinued operations.

Amounts expected to be amortized from accumulated other comprehensive earnings (loss) into net periodic benefit cost during 2019 are as follows: Qualified Defined Benefits Non-Qualified Supplemental Benefits Other Post-Retirement Benefits U.S. Plan Non-U.S. Plans Amortization of: Prior service cost (credit) $ 303 $ (238) $ 2811 $ 13 Recognized actuarial loss (gain) — 3,241 (2,280) (70) Transition obligation — — — — Total $ 303 $ 3,003 $ 531 $ (57) Assumptions The Company determines actuarial assumptions on an annual basis. The weighted average assumptions used in determining the benefit obligations were as follows: Qualified Defined Benefits Non-Qualified Supplemental Benefits Other Post-Retirement Benefits U.S. Plan Non-U.S. Plans 2018 2017 2018 2017 2018 2017 2018 2017 Discount rate 4.35 % 3.65 % 1.83 % 1.94 % 4.30 % 3.57 % 4.15 % 3.50 % Average wage increase 4.50 % 4.00 % 2.10 % 2.33 % 4.50 % 4.50 % na na Ultimate medical trend rate na na na na na na 5.00 % 2.33 % The weighted average assumptions used in determining the net periodic benefit cost were as follows: Qualified Defined Benefits Non- Qualified Supplemental Benefits Other Post-Retirement Benefits U.S. Plan Non-U.S. Plans 2018 2017 2016 2018 2017 2016 2018 2017 2016 2018 2017 2016 Discount rate 4.2%/3.65% (1) 4.10 % 4.40 % 1.94 % 2.06 % 2.32 % 3.57 % 3.97 % 4.18 % 3.50 6.49 % 4.00 % Average wage increase 4.00 % 4.00 % 4.00 % 2.33 % 2.34 % 2.25 % 4.50 % 4.50 % 4.50 % na na na Expected return on plan assets 6.8%/7.25% (1) 7.25 % 7.25 % 4.66 % 4.73 % 4.95 % na na na na na na (1) The separation of Apergy triggered a pension plan curtailment which required a re-measurement of the Plan's benefit obligation in the second quarter 2018, assuming a discount rate of 4.2% and an expected return on assets of 6.8%. The Company’s discount rate assumption is determined by developing a yield curve based on high quality corporate bonds with maturities matching the plans’ expected benefit payment streams. The plans’ expected cash flows are then discounted by the resulting year-by-year spot rates. The remeasurement in the second quarter of 2018, triggered by the Apergy spin-off, resulted in an increase to the discount rate used in determining net periodic benefit cost from 3.65% to 4.20% for the balance of 2018. For other post-retirement benefit measurement purposes, a 7.00% annual rate of increase in the per capita cost of covered benefits (i.e., health care cost trend rates) was assumed for 2019. The rate was assumed to decrease gradually to 5.00% by the year 2027 and remain at that level thereafter. The health care cost trend rate assumption can have an effect on the amounts reported. For example, increasing (decreasing) the assumed health care cost trend rates by one percentage point in each year would increase (decrease) the accumulated other post-retirement benefit obligation as of December 31, 2018 by $75 and $(68), respectively, and would have a negligible impact on the net post-retirement benefit cost for 2018. Plan Assets The primary financial objective of the plans is to secure participant retirement benefits. Accordingly, the key objective in the plans’ financial management is to promote stability and, to the extent appropriate, growth in the funded status. Related and supporting financial objectives are established in conjunction with a review of current and projected plan financial requirements. As it relates to the funded defined benefit pension plans, the Company’s funding policy is consistent with the funding requirements of the Employment Retirement Income Security Act ("ERISA") and applicable international laws. The Company is responsible for overseeing the management of the investments of the plans’ assets and otherwise ensuring that the plans’ investment programs are in compliance with ERISA, other relevant legislation and related plan documents. Where relevant, the Company has retained professional investment managers to manage the plans’ assets and implement the investment process. The investment managers, in implementing their investment processes, have the authority and responsibility to select appropriate investments in the asset classes specified by the terms of their applicable prospectus or investment manager agreements with the plans. The assets of the plans are invested to achieve an appropriate return for the plans consistent with a prudent level of risk. The asset return objective is to achieve, as a minimum over time, the passively managed return earned by market index funds, weighted in the proportions outlined by the asset class exposures identified in the plans’ strategic allocation. The expected return on assets assumption used for pension expense is developed through analysis of historical market returns, statistical analysis, current market conditions and the past experience of plan asset investments. Overall, it is projected that the investment of plan assets within Dover’s U.S. defined benefit plan will achieve a net return over time from the asset allocation strategy of 6.80%. The Company’s actual and target weighted average asset allocation for our U.S. Corporate Pension Plan was as follows: 2018 2017 Current Target Equity securities 36 % 57 % 40 % Fixed income 55 % 33 % 55 % Real estate and other 9 % 10 % 5 % Total 100 % 100 % 100 % While the non-U.S. investment policies are different for each country, the long-term objectives are generally the same as for the U.S. pension assets. The Company's non-U.S. plans were expected to achieve rates of return on invested assets of 4.66% in 2018, 4.73% in 2017 and 4.95% in 2016. The fair values of both U.S. and non-U.S. pension plan assets by asset category within the fair value hierarchy (as defined in Note 12 — Financial Instruments) were as follows: U.S. Qualified Defined Benefits Plan 12/31/2018 12/31/2017 Level 1 Level 2 Total Fair Value Level 1 Level 2 Total Fair Value Corporate bonds — 150,179 150,179 — 74,509 74,509 Government securities 1,586 113,931 115,517 2,766 130,774 133,540 Interest-bearing cash and short-term investments 2,066 — 2,066 1,222 — 1,222 Total investments at fair value 3,652 264,110 267,762 3,988 205,283 209,271 Investments measured at net asset value* Collective funds — — 175,963 — — 352,481 Real estate investments — — 32,686 — — 48,294 Short-term investment funds — — 12,489 — — 7,794 Total investments 3,652 264,110 488,900 3,988 205,283 617,840 The Company had no level 3 U.S. Plan assets at December 31, 2018 and 2017.

These are included to permit reconciliation of the fair value hierarchy to the aggregate pension plan assets. Common stocks represent investments in domestic and foreign equities, which are publicly traded on active exchanges and are valued based on quoted market prices. Fixed income investments include U.S. Treasury bonds and notes, which are valued based on quoted market prices, as well as investments in other government and municipal securities and corporate bonds, which are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Mutual funds are categorized as either Level 1, 2 or Net Asset Value (the "NAV") as a practical expedient depending on the nature of the observable inputs. Collective trusts and real estate investment funds are valued using NAV as a practical expedient as of the last business day of the year. The NAV is based on the underlying value of the assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding. The value of the underlying assets is based on quoted prices in active markets. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The availability of observable data is monitored by plan management to assess appropriate classification of financial instruments within the fair value hierarchy. Depending upon the availability of such inputs, specific securities may transfer between levels. In such instances, the transfer is reported at the end of the reporting period. The fair value measurement of plan assets using significant unobservable inputs (Level 3) changed during 2017 and 2018, due to the following: Level 3 Balance at January 1, 2017 $ 4,354 Actual return on plan assets: Relating to assets sold during the period 28 Relating to assets still held at December 31, 2017 280 Sales (456) Foreign currency translation 386 Balance at December 31, 2017 $ 4,592 Actual return on plan assets: Relating to assets still held at December 31, 2018 (29) Insurance contracts added 16,975 Foreign currency translation (255) Balance at December 31, 2018 $ 21,283 Future Estimates Benefit Payments Estimated future benefit payments to retirees, which reflect expected future service, are as follows: Qualified Defined Benefits Non-Qualified Supplemental Benefits Other Post-Retirement Benefits U.S. Plan Non-U.S. Plans 2019 $ 33,990 $ 9,069 $ 13,500 $ 717 2020 37,086 8,484 5,353 705 2021 37,217 9,043 11,474 681 2022 36,896 9,339 8,742 663 2023 36,117 10,754 4,220 641 2024 - 2028 166,962 63,653 18,933 2,794 Contributions

Cash flow hedges consist mainly of foreign currency forward contracts. The Company recognizes the realized gains and losses on its cash flow hedges in the same line item as the hedged transaction, such as revenue, cost of goods and services, or selling, general and administrative expenses in the Consolidated Statements of Earnings.

Segment Reporting [Abstract]
Segment Information	18. Segment Information The Company's businesses are aligned around its key end markets to better focus on growth strategies, provide increased opportunities to leverage Dover's scale and capitalize on productivity initiatives. Operating segments are defined as the components of an enterprise for which separate financial information is available and regularly evaluated by the entity's chief operating decision maker ("CODM") or decision-making group composed of Dover's Chief Executive Officer and Chief Financial Officer, in making resource allocation decisions and evaluating performance. As described in Note 2 - Spin-off of Apergy Corporation, Dover completed the distribution of Apergy to its shareholders on May 9, 2018. Apergy holds entities conducting upstream energy businesses previously included in the Energy segment. Following completion of the spin-off, the retained Precision Components (Bearings & Compression) and Tulsa Winch Group businesses, which were historically reported within the former Energy segment, became part of the Fluids and Engineered Systems segments, respectively. As a result of the spin-off of Apergy, the Company no longer has the Energy segment. Effective the second quarter of 2018, the Company categorizes its operating companies into three reportable segments based on how the CODM analyze performance, allocate capital and make strategic and operational decisions. The three reportable segments are as follows: • Engineered Systems segment is comprised of two platforms, Printing & Identification and Industrials, and is focused on the design, manufacture and service of critical equipment and components serving the fast-moving consumer goods, digital textile printing, vehicle service, environmental solutions and industrial end markets. • Fluids segment, serving the Fueling & Transport, Pumps and Process Solutions end markets, is focused on the safe handling of critical fluids, and providing critical components to the retail fueling, chemical, hygienic, oil and gas, power generation and industrial end markets. • The Refrigeration & Food Equipment segment is a provider of customer-driven solutions and services for safe and efficient production and processing of fuels worldwide and has a strong presence in the bearings and compression components and automation markets. Segment financial information and a reconciliation of segment results to consolidated results follows: Years Ended December 31, 2018 2017 2016 Revenue: Engineered Systems $ 2,742,948 $ 2,667,984 $ 2,446,665 Fluids 2,797,338 2,555,065 1,977,050 Refrigeration & Food Equipment 1,453,093 1,599,105 1,620,339 Intra-segment eliminations (1,261) (1,268) (830) Total consolidated revenue $ 6,992,118 $ 6,820,886 $ 6,043,224 Earnings from continuing operations: Segment earnings: (1) Engineered Systems $ 451,270 $ 604,484 $ 399,209 Fluids 389,804 368,630 246,545 Refrigeration & Food Equipment 136,119 193,822 283,628 Total segment earnings 977,193 1,166,936 929,382 Corporate expense / other (2) 129,724 154,664 115,521 Interest expense 130,972 144,948 135,969 Interest income (8,881) (8,491) (6,752) Earnings before provision for income taxes and discontinued operations 725,378 875,815 684,644 Provision for income taxes 134,233 129,152 182,516 Earnings from continuing operations $ 591,145 $ 746,663 $ 502,128 Segment margins: Engineered Systems 16.5 % 22.7 % 16.3 % Fluids 13.9 % 14.4 % 12.5 % Refrigeration & Food Equipment 9.4 % 12.1 % 17.5 % Total Segments 14.0 % 17.1 % 15.4 % Net earnings 8.5 % 10.9 % 8.3 % Depreciation and amortization: Engineered Systems $ 75,879 $ 85,447 $ 78,173 Fluids 140,444 135,821 101,266 Refrigeration & Food Equipment 60,477 57,207 65,018 Corporate 5,780 4,803 5,215 Consolidated total $ 282,580 $ 283,278 $ 249,672 Capital expenditures: Engineered Systems $ 47,044 $ 37,495 $ 32,374 Fluids 86,566 90,625 68,147 Refrigeration & Food Equipment 32,482 32,541 23,651 Corporate 4,902 9,407 15,406 Consolidated total $ 170,994 $ 170,068 $ 139,578 (1) Segment earnings includes non-operating income and expense directly attributable to the segments.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	20. Stockholders' Equity The Company has the authority to issue up to 100,000 shares of $100 par preferred stock and up to 500,000,000 shares of $1.00 par common stock. There were no issuances of preferred stock. As of December 31, 2018 and 2017, the Company issued 257,822,352 and 256,992,261 shares of common stock and had 112,905,810 and 102,168,868 treasury shares, held at cost, respectively. Share Repurchases During the years ended December 31, 2018 and 2017, under the January 2015 authorization which expired on January 9, 2018, the Company repurchased 440,608 and 1,059,682 shares of common stock at a total cost of $44,977 and $105,023, or $102.08 and $99.11 per share, respectively. There were 5,271,168 shares available for repurchase under this authorization upon expiration. In February 2018, the Company's Board of Directors approved a new standing share repurchase authorization, whereby the Company may repurchase up to 20,000,000 shares of its common stock through December 31, 2020. This share repurchase authorization replaced the January 2015 share repurchase authorization. On May 22, 2018, the Company entered into a $700,000 accelerated share repurchase agreement (the “ASR Agreement”) with Goldman Sachs & Co. LLC (“Goldman Sachs”) to repurchase its shares in an accelerated share repurchase program (the “ASR Program”). The Company conducted the ASR Program under the February 2018 share repurchase authorization. The Company funded the ASR Program with funds received from Apergy in connection with the consummation of the Apergy spin-off. Under the terms of the ASR Agreement, the Company paid Goldman Sachs $700,000 on May 24, 2018 and on that date received initial deliveries of 7,078,751 shares, representing a substantial majority of the shares expected to be retired over the course of the ASR Agreement. In December 2018 Goldman Sachs delivered a total of 1,463,815 shares which completed the ASR Program. During 2018, the Company received a total of 8,542,566 shares as part of the ASR Agreement. The total number of shares ultimately repurchased under the ASR Agreement was based on the volume-weighted average share price of Dover’s common stock during the calculation period of the ASR Program, less a discount, which was $81.94 over the term of the ASR Program. Under the February 2018 share repurchase authorization, exclusive of the ASR Agreement, the Company repurchased 1,753,768 shares of common stock during the year ended December 31, 2018 at a total cost of $150,000, or $85.53 per share. As of December 31, 2018, 9,703,666 shares remain authorized for repurchase under the February 2018 share repurchase authorization. Together with other repurchases in December 2017 and over the course of 2018, the Company has completed the $1 billion of share repurchases it announced in November 2017.

Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business [Text Block]	Description of Business Dover Corporation ("Dover" or "Company") is a diversified global manufacturer delivering innovative equipment and components, specialty systems, consumable supplies, software and digital solutions and support services. The Company also provides supporting engineering, testing and other similar services, which are not significant in relation to consolidated revenue. The Company’s businesses are based primarily in the United States of America and Europe with manufacturing and other operations throughout the world. The Company operates through three business segments that are aligned with the key end markets they serve: Engineered Systems, Fluids, and Refrigeration & Food Equipment. For additional information on the Company’s segments, see Note 18 — Segment Information.
Principles of Consolidation [Policy Text Block]	Principles of ConsolidationThe consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The results of operations of acquired businesses are included from the dates of acquisitions. As discussed in Note 5 — Discontinued and Disposed Operations, the Company is reporting the assets, liabilities, results of operations and cash flows of Apergy prior to the spin-off, as discontinued operations for all periods presented.
Use of Estimates [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying disclosures. These estimates may be adjusted due to changes in future economic, industry, or customer financial conditions, as well as changes in technology or demand. Estimates are used for, but not limited to, allowances for doubtful accounts receivable, net realizable value of inventories, restructuring reserves, warranty reserves, pension and post-retirement plans, stock-based compensation, useful lives for depreciation and amortization of long-lived assets, future cash flows associated with impairment testing for goodwill, indefinite-lived intangible assets and other long-lived assets, deferred tax assets, uncertain income tax positions and contingencies. Actual results may ultimately differ from estimates, although management does not believe such differences would materially affect the consolidated financial statements in any individual year. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the Consolidated Financial Statements in the period that they are determined.
Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term investments, which are highly liquid in nature and have original maturities at the time of purchase of three months or less. The carrying value of cash and cash equivalents approximate fair value.
Allowance for Doubtful Accounts [Policy Text Block]	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at face amounts less an allowance for doubtful accounts. The allowance is an estimate based on historical collection experience, current economic and market conditions and a review of the current status of each customer's trade accounts receivable. Management evaluates the aging of the accounts receivable balances and the financial condition of its customers to estimate the amount of accounts receivable that may not be collected in the future and records the appropriate provision.
Inventories [Policy Text Block]	Inventories Inventories for the majority of the Company’s subsidiaries, including all international subsidiaries, are stated at the lower of cost, determined on the first-in, first-out (FIFO) basis, or net realizable value. Other domestic inventories are stated at cost, determined on the last-in, first-out (LIFO) basis, which is less than market value.
Property, Plant and Equipment [Policy Text Block]	Property, Plant and EquipmentProperty, plant and equipment includes the historical cost of land, buildings, machinery and equipment, purchased software and significant improvements to existing plant and equipment or, in the case of acquisitions, a fair market value appraisal of assets. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When property or equipment is sold or otherwise disposed of, the related cost and accumulated depreciation is removed from the respective accounts and the gain or loss realized on disposition is reflected in earnings. The Company depreciates its assets on a straight-line basis over their estimated useful lives as follows: buildings and improvements 5 to 31.5 years; machinery and equipment 3 to 7 years; furniture and fixtures 3 to 7 years; vehicles 3 to 7 years; and software 3 to 10 years.
Derivatives Instruments [Policy Text Block]	Derivative Financial Instruments The Company uses derivative financial instruments to hedge its exposures to various risks, including interest rate and foreign currency exchange rate risk. The Company does not enter into derivative financial instruments for speculative purposes and does not have a material portfolio of derivative financial instruments. Derivative financial instruments used for hedging purposes must be designated and effective as a hedge of the identified risk exposure at inception of the contract. The Company recognizes all derivatives as either assets or liabilities on the consolidated balance sheet and measures those instruments at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair value of both the derivatives and of the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivatives is recorded as a component of other comprehensive earnings and subsequently recognized in net earnings when the hedged items impact earnings.
Goodwill and Indefinite-Lived Intangible Assets [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over the fair value of net assets acquired. Goodwill and certain other intangible assets deemed to have indefinite lives (primarily trademarks) are not amortized. For goodwill, impairment tests are required at least annually, or more frequently if events or circumstances indicate that it may be impaired, or when some portion but not all of a reporting unit is disposed of or classified as assets held for sale. Based on its current organizational structure, the Company identified seven reporting units for which cash flows are determinable and to which goodwill may be allocated. The Company performs its goodwill impairment test annually in the fourth quarter at the reporting unit level. A quantitative test is used to determine existence of goodwill impairment and the amount of the impairment loss at the reporting unit level. The quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill. The Company uses an income-based valuation method, determining the present value of estimated future cash flows, to estimate the fair value of a reporting unit. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Factors used in the impairment analysis require significant judgment, and actual results may differ from assumed and estimated amounts. The Company uses its own market assumptions including internal projections of future cash flows, discount rates and other assumptions considered reasonable and inherent in the analysis. These forecasts are based on historical performance and future estimated results. The discount rates used in these analyses vary by reporting unit and are based on a capital asset pricing model and published relevant industry rates. The Company uses discount rates commensurate with the risks and uncertainties inherent to each reporting unit and in the internally developed forecasts. See Note 8 — Goodwill and Other Intangible Assets for further discussion of the Company's annual goodwill impairment test and results. The Company uses an income-based valuation method to annually test its indefinite-lived intangible assets for impairment. The fair value of the intangible asset is compared to its carrying value. This method uses the Company’s own market assumptions, which are considered reasonable and inherent in the analysis. Any excess of carrying value over the estimated fair value is recognized as an impairment loss. No impairment of indefinite-lived intangible assets was required for the years ended December 31, 2018, 2017, or 2016.
Other Intangible Assets [Policy Text Block]	Other intangible assets with determinable lives primarily consist of customer intangibles, unpatented technologies, patents and trademarks. The other intangible assets are amortized over their estimated useful lives, ranging from 5 to 15 years.
Long-Lived Assets [Policy Text Block]	Long-lived assets (including definite-lived intangible assets) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, such as a significant sustained change in the business climate. If an indicator of impairment exists for any grouping of assets, an estimate of undiscounted future cash flows is produced and compared to its carrying value. If an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value, as determined by an estimate of discounted future cash flows.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring Accruals From time to time, the Company takes actions to reduce headcount, close facilities, or otherwise exit operations. Such restructuring activities at an operation are recorded when management has committed to an exit or reorganization plan and when termination benefits are probable and can be reasonably estimated based on circumstances at the time the restructuring plan is approved by management or when termination benefits are communicated. Exit costs include future minimum lease payments on vacated facilities and other contractual terminations. In addition, asset impairments may be recorded as a result of an approved restructuring plan. The accrual of both severance and exit costs requires the use of estimates. Though the Company believes that its estimates accurately reflect the anticipated costs, actual results may be different from the original estimated amounts.
Foreign Currency [Policy Text Block]	Foreign Currency Assets and liabilities of non-U.S. subsidiaries, where the functional currency is not the U.S. dollar, have been translated at year-end exchange rates and profit and loss accounts have been translated using weighted-average monthly exchange rates. Foreign currency translation gains and losses are included in the Consolidated Statements of Comprehensive Earnings as a component of other comprehensive earnings (loss). Assets and liabilities of an entity that are denominated in currencies other than an entity’s functional currency are re-measured into the functional currency using end of period exchange rates or historical rates, where applicable to certain balances. Gains and losses related to these re-measurements are recorded within the Consolidated Statements of Earnings as a component of other expense (income), net. Gains and losses arising from intercompany foreign currency transactions that are of a long-term investment in nature are reported in the same manner as translation adjustments.
Revenue Recognition [Policy Text Block]	Revenue Recognition Effective January 1, 2018, the Company adopted Accounting Standard Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606” or “ASC 606”). Under Topic 606, a contract with a customer is an agreement which both parties have approved, that creates enforceable rights and obligations, has commercial substance and where payment terms are identified and collectability is probable. Once the Company has entered a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as discounts and volume rebates. Prior to 2018, revenue is recognized when all the following conditions are satisfied: a) persuasive evidence of an arrangement exists, b) price is fixed or determinable, c) collectability is reasonably assured and d) delivery has occurred or services have been rendered. The majority of the Company’s revenue is generated through the manufacture and sale of a broad range of specialized products and components, with revenue recognized upon transfer of control, title and risk of loss, which is generally upon shipment. Service revenue represents less than 5% of total revenue and is recognized as the services are performed. In limited cases, revenue arrangements with customers require delivery, installation, testing, certification, or other acceptance provisions to be satisfied before revenue is recognized. The Company includes shipping costs billed to customers in revenue and the related shipping costs in cost of goods and services.
Share-based Compensation [Policy Text Block]	Stock-Based Compensation The principal awards issued under the Company’s stock-based compensation plans include non-qualified stock appreciation rights ("SARs"), restricted stock units and performance share awards. The cost for such awards is measured at the grant date based on the fair value of the award. At the time of grant, the Company estimates forfeitures, based on historical experience,
Income Taxes [Policy Text Block]	Income Taxes The provision for income taxes includes federal, state, local and non-U.S. taxes. Tax credits, primarily for research and experimentation, are recognized as a reduction of the provision for income taxes in the year in which they are available for tax purposes. Deferred taxes are provided using enacted rates on the future tax consequences of temporary differences. Temporary differences include the differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis and the tax benefit of carryforwards. A valuation allowance is established for deferred tax assets for which realization is not assured. In assessing the need for a valuation allowance, management considers all available evidence, including the future reversal of existing taxable temporary differences, taxable income in carryback periods, prudent and feasible tax planning strategies and estimated future taxable income. The valuation allowance can be affected by changes to tax regulations, interpretations and rulings, changes to enacted statutory tax rates and changes to future taxable income estimates. Tax benefits are recognized from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position in consideration of applicable tax statutes and related interpretations and precedents. Tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized on ultimate settlement. On December 22, 2017, the U.S. bill commonly referred to as the Tax Cuts and Jobs Act (“Tax Reform Act”) was enacted, which significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a one-time repatriation tax on deemed repatriated earnings of foreign subsidiaries. The Tax Reform Act reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. The Tax Reform Act also provided for a one-time deemed repatriation of post-1986 undistributed foreign subsidiary earnings and profits (“E&P”) through the year ended December 31, 2017. The Global Intangible Low-Taxed Income ("GILTI") provisions of the Tax Reform Act require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company is subject to incremental U.S. tax on GILTI income due to expense allocations required by the U.S. foreign tax credit rules. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company recognized the provisional tax impacts related to deemed repatriated earnings and the benefit for the revaluation of deferred tax assets and liabilities, and included these amounts in its consolidated financial statements for the year ended December 31, 2017. In accordance with SAB 118, the Company finalized the financial reporting impact of the Tax Reform Act in the fourth quarter of 2018. For the year ended December 31, 2018, the Company recorded a $4.2 million net tax benefit, which resulted in a 0.6% decrease in the effective tax rate, as an adjustment to provisional estimates as a result of additional regulatory guidance and changes in interpretations and assumptions the Company has made as a result of the Tax Reform Act.
Research and Development Costs [Policy Text Block]	Research and Development Costs Research and development costs, including qualifying engineering costs, are expensed when incurred and amounted to $143,033 in 2018, $130,536 in 2017 and $115,840 in 2016. These costs as a percent of revenue were 2.0% in 2018 and 1.9% in 2017 and 2016. Revisions were made to the 2017 and 2016 research and development costs and impacted only the
Advertising [Policy Text Block]	Advertising Costs Advertising costs are expensed when incurred and amounted to $26,831 in 2018, $33,369 in 2017 and $35,035 in 2016.
Risk, Retention, Insurance [Policy Text Block]	Risk, Retention, InsuranceThe Company currently self-insures its product and commercial general liability claims up to $5.0 million per occurrence, its workers’ compensation claims up to $0.8 million per occurrence and automobile liability claims up to $5.0 million per occurrence. Third-party insurance provides primary level coverage in excess of these amounts up to certain specified limits. In addition, the Company has excess liability insurance from third-party insurers on both an aggregate and an individual occurrence basis well in excess of the limits of the primary coverage. A worldwide program of property insurance covers the Company’s owned and leased property and any business interruptions that may occur due to an insured hazard affecting those properties, subject to reasonable deductibles and aggregate limits. The Company’s property and casualty insurance programs contain various deductibles that, based on the Company’s experience, are typical and customary for a company of its size and risk profile. The Company does not consider any of the deductibles to represent a material risk to the Company. The Company generally maintains deductibles for claims and liabilities related primarily to workers’ compensation, health and welfare claims, general commercial, product and automobile liability, cybersecurity risks, property damage and business interruption resulting from certain events. The Company accrues for claim exposures that are probable of occurrence and can be reasonably estimated. As part of the Company’s risk management program, insurance is maintained to transfer risk beyond the level of self-retention and provide protection on both an individual claim and annual aggregate basis.
Reclassification [Policy Text Block]	Reclassifications – Certain amounts in prior years have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements [Policy Text Block]	Recent Accounting Pronouncements Recently Issued Accounting Standards The following standards, issued by the Financial Accounting Standards Board ("FASB"), will, or are expected to, result in a change in practice and/or have a financial impact to the Company’s Consolidated Financial Statements: In August 2018, the FASB issued Accounting Standards Update ("ASU") 2018-15, Intangibles-Goodwill and Other Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for interim and annual periods for the Company beginning on January 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is in the process of assessing the impact of this ASU on its Consolidated Financial Statements but does not expect this update to have a material impact on the Company's Consolidated Financial Statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU provides new guidance about income statement classification and eliminates the requirement to separately measure and report hedge ineffectiveness. The entire change in fair value for qualifying hedge instruments included in the effectiveness will be recorded in other comprehensive income (OCI) and amounts deferred in OCI will be reclassified to earnings in the same income statement line item in which the earnings effect of the hedged item is reported. The guidance is effective for interim and annual periods for the Company on January 1, 2019, with early adoption permitted. The Company does not expect the adoption of this ASU to have a material impact on its Consolidated Financial Statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The guidance is effective for interim and annual periods for the Company on January 1, 2020, with early adoption permitted. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. Currently, the Company believes that the most notable impact of this ASU may relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on trade accounts receivable and the recognition of credit losses. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which amended existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. This ASU also provides clarifications surrounding the presentation of the effects of leases in the income statement and statement of cash flows. This guidance was effective for the Company on January 1, 2019. In addition, the FASB issued ASU 2018-11, Leases Targeted Improvements which provides an additional transition method that allows entities to apply the new leases standard at adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. The Company elected this new transition method when it adopted ASU 2016-02 on January 1, 2019. During the second half of 2017, the Company developed a project plan to guide the implementation of ASU 2016-02. The Company completed this plan including surveying the Company’s businesses, assessing the Company’s portfolio of leases and compiling a central repository of active leases. The Company also implemented a lease accounting software solution to support the new reporting requirements and established a future lease process to keep the lease accounting portfolio up to date. The Company evaluated key policy elections and considerations under the standard and completed an internal policy as well as training to address the new standard requirements. The Company plans to elect the package of practical expedients and will not apply the recognition requirements to short-term leases. Although management continues to evaluate the effect to the Company's Consolidated Balance Sheets and disclosures, management currently estimates total assets and liabilities will increase approximately $150 million to $200 million upon adoption, before considering deferred taxes. Management does not expect a material impact to the Company’s Consolidated Statements of Earnings or Cash Flows. Recently Adopted Accounting Standards In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740) Amendments to SEC Paragraphs Pursuant to the SEC Staff Accounting Bulletin No. 118 ("SAB 118"). This ASU provides guidance on income tax accounting implications under the Tax Reform Act. SAB 118 addressed the application of GAAP to situations when a registrant does not have the necessary information available, prepared and analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act and allows companies to record provisional amounts during the re-measurement period not to exceed one year after the enactment date while the accounting impact remains under analysis. This guidance was effective immediately upon issuance. See Note 13 — Income Taxes for further details. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU allows for the reclassification from Accumulated Other Comprehensive Income ("AOCI") to retained earnings for tax effects resulting from the Tax Reform Act that are stranded in AOCI. ASU 2018-02, however, does not change the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. The Company early adopted this guidance on January 1, 2018, and elected to reclassify the stranded tax effects from AOCI to retained earnings of $12.9 million. The stranded tax effects were specifically identified and represented the difference between the change in the amount of income tax from 35% to 21%, recognized in AOCI primarily for the deferred taxes associated with pensions, which were recognized in the Consolidated Statement of Earnings for the year ended December 31, 2017. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU changes the income statement presentation of defined benefit and post-retirement benefit plan expense by requiring separation between operating expense (service cost component of net periodic benefit expense) and non-operating expense (all other components of net periodic benefit expense, including interest cost, amortization of prior service cost, curtailments and settlements, etc.). The operating expense component is reported with similar compensation costs while the non-operating components are reported outside of operating income. The non-operating components are reported in the other (income) expense, net line item in the Consolidated Statement of Earnings. The Company’s non-operating cost components of net periodic cost were a benefit (cost) of $5.8 million, $8.6 million and $(2.4) million during the years ended December 31, 2018 and 2017 and 2016 respectively. The impact of this adoption resulted in a reclassification to the Company’s Condensed Consolidated Statement of Earnings for the year ended December 31, 2017 and 2016 in which previously reported selling, general and administrative expenses were adjusted by $8.6 million and $(2.4) million, respectively, with a corresponding adjustment to other income, net. The Company utilized a practical expedient included in the ASU which allowed the Company to use amounts previously disclosed in its pension and other post-retirement benefits note for the prior period as the estimation basis for applying the required retrospective presentation requirements. The Company adopted this guidance on January 1, 2018. In January 2017, the FASB issued ASU 2017-01, Business combinations (Topic 805): Clarifying the definition of a business, which clarifies the definition of a business and assists entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under this guidance, when substantially all of the fair value of gross assets acquired is concentrated in a single asset (or group of similar assets), the assets acquired would not represent a business. In addition, in order to be considered a business, an acquisition would have to include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The amended guidance also narrows the definition of outputs by more closely aligning it with how outputs are described in FASB guidance for revenue recognition. The Company adopted this guidance on January 1, 2018. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The Company adopted this guidance on January 1, 2018. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements.

The pro forma information is not necessarily indicative of the results that actually would have occurred, nor does it indicate future operating results. The supplemental pro forma earnings reflect adjustments to earnings from continuing operations as reported in the Consolidated Statements of Earnings to exclude nonrecurring expense related to the fair value adjustments to acquisition-date inventory (after-tax) and acquisition-related costs (after-tax) from the year ended December 31, 2018. These adjustments were not material in 2018 and 2017. The supplemental pro forma earnings for the 2017 period were similarly adjusted for 2017 acquisitions charges as if incurred at the beginning of 2016. The 2018 and 2017 supplemental pro forma earnings are also adjusted to reflect the comparable impact of additional depreciation and amortization expense, net of tax, resulting from the fair value measurement of tangible and intangible assets relating to 2018 and 2017 acquisitions.
