Revenue from Contract with Customer [Abstract]

Contract with Customer, Asset and Liability [Table Text Block]

The following table provides information about contract assets and contract liabilities from contracts with customers:


	12/31/2019		12/31/2018		At Adoption

Contract assets	$	14,894	$	9,330	$	11,932
Contract liabilities - current	44,001		36,461		48,268
Contract liabilities - non-current	9,121		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.

The revenue recognized during 2019 and 2018 that was included in the contract liability at the beginning of the respective periods amounted to $31,283 and $38,410.

Commitments and Contingent Liabilities	Dec. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	16. Commitments and Contingent Liabilities 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. 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. At December 31, 2019 and 2018, the Company has reserves totaling $30,608 and $31,797, respectively, for environmental and other matters, including private party claims for exposure to hazardous substances, that are probable and estimable. The Company and some of its subsidiaries are also parties to a number of other legal proceedings incidental to their businesses. These proceedings primarily involve claims by private parties alleging injury arising out of use of the Company’s products, exposure to hazardous substances, patent infringement, employment matters and commercial disputes. Management and legal counsel, at least quarterly, review the probable outcome of such proceedings, the costs and expenses reasonably expected to be incurred and currently accrued to-date and consider the availability and extent of insurance coverage. The Company has reserves for other legal matters that are probable and estimable, and at December 31, 2019 and 2018, these reserves were not significant. While it is not possible at this time to predict the outcome of these legal actions, in the opinion of management, based on the aforementioned reviews, the Company is not currently involved in any legal proceedings which, individually or in the aggregate, could have a material effect on its financial position, results of operations, or cash flows.

Share-based Compensation [Abstract]

15. 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 of 2018, the Company granted equity awards to its new President and Chief Executive Officer. Awards were 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.

In 2018, 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 in 2018. 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,
	2019		2018		2017
Pre-tax stock-based compensation expense (continuing)	$	29,702	$	23,698	$	24,073
Tax benefit	(2,490)		(2,722)		(8,411)
Total stock-based compensation expense, net of tax	$	27,212	$	20,976	$	15,662

Pre-tax stock-based compensation expense attributable to Apergy employees for the years ended December 31, 2018 and 2017 was $744 and $2,454, respectively. These costs are reported within earnings from discontinued operations in the Consolidated Statement of Earnings.

SARs

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 years of service and expire at the end of ten years.

In 2019, 2018 and 2017, the Company issued SARs covering 615,089, 757,603 and 1,028,116 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:


	2019			2018							2017
Risk-free interest rate	2.51		%	2.58	%	—	2.87%	1.80		%
Dividend yield	2.13		%	1.99	%	—	2.43%	2.27		%
Expected life (years)	5.6			5.6		—	5.7	4.6
Volatility	22.35		%	20.95	%	—	21.20%	21.90		%
Grant price ⁽¹⁾	$	91.20		$79.75		—	$82.09	$	66.85
Fair value at date of grant ⁽¹⁾	$	17.55		$14.58		—	$15.41	$	10.65

⁽¹⁾ 2018 and 2017 grant prices and fair values at date of grant 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, 2019 is as follows:


	SARs
	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)
Outstanding at January 1, 2019	5,329,204	$	60.19
Granted	615,089	91.24

Exercisable at December 31, 2019	1,579,082	$	57.26	4.3

The following table summarizes information about outstanding SARs at December 31, 2019:


	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

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 2019, 2018 and 2017, the Company issued performance shares covering 35,172, 122,459 and 57,958 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 2019, 2018 and 2017 are as follows for the year ended December 31, 2019:



	2019	2018				2017
Fair value per share at date of grant ⁽¹⁾	$91.20	$79.75	-	$82.09	$66.85
Average attainment rate reflected in expense	200.3%	282.4%				237.0	%

⁽¹⁾ 2018 and 2017 fair values per share at date of grant 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, 2019 is as follows:


	Number of Shares	Weighted Average Grant-Date Fair Value
Unvested at January 1, 2019	144,957	$	76.99
Granted	35,172	91.33


Forfeited	(19,026)	76.46
Vested	(23,294)	66.85
Unvested at December 31, 2019	137,809	$	82.45

Unrecognized compensation expense related to unvested performance shares as of December 31, 2019 was $13,016, which will be recognized over a weighted average period of 1.3 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 124,929, 284,721 and 174,203 of restricted stock units in 2019, 2018 and 2017, 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, 2019 is as follows:


	Number of Shares	Weighted Average Grant-Date Fair Value
Unvested at January 1, 2019	390,481	$	73.35
Granted	124,929	91.34


Forfeited	(23,706)	84.02
Vested	(167,151)	69.55
Unvested at December 31, 2019	324,553	$	81.45

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 and 2017 include the historical results of Apergy prior to its distribution on May 9, 2018. The years ended December 31, 2018 and 2017 included costs incurred by Dover to complete the spin-off of Apergy amounting to $46,384 and $15,270, 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 were classified within discontinuing operations. See Note 2 — Spin-off of Apergy Corporation and Note 17 — Employee Benefit Plans for further information.

Summarized results of the Company's discontinued operations are as follows:


	Years Ended December 31,
		2018		2017
Revenue		$	403,688	$	1,010,135
Cost of goods and services		254,205		648,805
Gross profit		149,483		361,330
Selling, general and administrative expenses		147,261		262,353
Operating earnings		2,222		98,977
Other expense, net		9,048		949
(Loss) earnings from discontinued operations before taxes		(6,826)		98,028
Provision (benefit) for income taxes		14,052		33,026
(Loss) earnings from discontinued operations, net of tax		$	(20,878)	$	65,002

On May 9, 2018, all assets and liabilities of Apergy were spun-off. Therefore, as of December 31, 2019 and 2018, there were no assets and liabilities classified as discontinued operations.

Disposed Businesses

2019

On March 29, 2019, the Company entered into a definitive agreement to sell Finder Pompe S.r.l ("Finder"), a wholly owned subsidiary, to Gruppo Aturia S.p.A (“Aturia”). As of March 31, 2019, Finder met the criteria to be classified as held for sale. The Company classified Finder's assets and liabilities separately on the consolidated balance sheet as of March 31, 2019.

Based on the total consideration from the sale, net of selling costs, the Company recorded a loss on the assets held for sale of $46,946 in the Condensed Consolidated Statements of Earnings during the three months ended March 31, 2019. The loss was comprised of an impairment on assets held for sale of $21,607 and $25,339 of foreign currency translation losses reclassified out of accumulated other comprehensive losses.

On April 2, 2019, Dover completed the sale of Finder to Aturia, which generated total cash proceeds of $24,218. The Finder business was included in the results of the Pumps & Process Solutions segment. The sale does not represent a strategic shift that will have a major effect on operations and financial results and, therefore, did not qualify for presentation as a discontinued operation.

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 Engineered Products 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

13. 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 and certain commodity risks. In order to manage these risks, the Company has hedged portions of its forecasted sales and purchases, which occur within the next twelve months that are denominated in non-functional currencies, with currency forward contracts designated as cash flow hedges. At December 31, 2019 and 2018, the Company had contracts with U.S. dollar equivalent notional amounts of $179,580 and $193,649, respectively, to exchange foreign currencies, principally the Pound sterling, Chinese yuan, Swedish krona, Euro, Canadian dollar and Swiss franc. The Company believes it is probable that all forecasted cash flow transactions will occur.

In addition, the Company had outstanding contracts at December 31, 2019 and 2018 with a total notional amount of $79,707 and $66,906, 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 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, 2019 and 2018 and the balance sheet lines in which they are recorded:


	Fair Value Asset (Liability)
	December 31, 2019		December 31, 2018		Balance Sheet Caption
Foreign currency forward	$	2,892	$	1,874	Prepaid and other current assets
Foreign currency forward	(476)		(1,165)		Other accrued expenses

For a cash flow hedge, the change in estimated fair value of a hedging instrument is recorded in accumulated other comprehensive earnings (loss), net of tax as a separate component of the Consolidated Statements of Stockholders' Equity and is reclassified into revenues and 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 that 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 €600,000 and €500,000 of euro-denominated notes issued November 9, 2016 and November 4, 2019, respectively, as a hedge of its net investment in euro-denominated operations. The Company also designated the 2020 Notes as a net investment hedge prior to the redemption of the notes. 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:


	2019		2018		2017
Gain/(loss) on euro-denominated debt	$	22,449	$	45,230	$	(125,262)


Tax (expense)/benefit	(4,714)		(9,498)		43,842
Gain/(loss) on net investment hedges, net of tax	$	17,735	$	35,732	$	(81,420)

Fair Value Measurements

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, 2019 and 2018 were as follows:


	December 31, 2019		December 31, 2018
	Level 2		Level 2
Assets:
Foreign currency cash flow hedges	$	2,892	$	1,874
Liabilities:
Foreign currency cash flow hedges	476		1,165

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, 2019 and 2018 was $3,322,033 and $3,132,330, 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, 2019 and 2018 due to the short-term nature of these instruments.

The discounts are being amortized to interest expense using the effective interest method over the life of the issuances. The deferred issuance costs are amortized on a straight-line basis over the life of the debt.

On March 15, 2018, the outstanding 5.45% notes with a principal value of $350,000 matured. The repayment of debt was funded by the Company's commercial paper program and existing cash balances.

On November 4, 2019, the Company issued €500,000 of 0.750% euro-denominated notes due 2027 and $300,000 of 2.950% notes due 2029 and notified the debt holders of our €300,000 2.125% notes due 2020 ("2020 Notes") and our $450,000 4.30% Notes due 2021 ("2021 Notes") of our intent to redeem these notes on December 4, 2019. The proceeds from the sale of euro-denominated notes of €494,685, net of discounts and issuance costs, were used in part to redeem the 2020 Notes. The proceeds from the sale of notes of $296,937, net of discounts and issuance costs, and the remaining funds from the sale of the euro-denominated notes, were used to fund the redemption of the 2021 Notes. Such redemption payments were made on December 4, 2019, which required the Company to pay a make whole premium to the bondholders, resulting in a loss of $23,543. The remainder of the proceeds will be used for general corporate purposes.

On October 4, 2019, the Company entered into a $1 billion five-year unsecured revolving credit facility with a syndicate banks (the “Credit Agreement”) that replaced a similar existing credit facility that was set to expire in November 2020. The Credit Agreement will expire on October 4, 2024. The Company may elect to have loans under the Credit Agreement bear interest at a rate based on a benchmark interbank offered rate specified for each currency and, in the case of US Dollars, an alternate base rate (as defined in the Credit Agreement) based on a prime rate plus a specified margin ranging from 0.805% to 1.20%, set on the basis of the credit rating accorded to the Company’s senior unsecured debt by S&P and Moody’s. The Credit Agreement requires the Company to pay a facility fee and imposes various restrictions on the Company such as, among other things, a requirement to maintain a minimum interest coverage ratio of EBITDA to consolidated net interest expense of not less than 3.0 to 1. The Company was in compliance with all covenants in the Credit Agreement and other long-term debt covenants at December 31, 2019 and had a coverage ratio of 10.6 to 1. The Company primarily uses this facility as liquidity back-up for its commercial paper program and has not drawn down any loans under the facility and does not anticipate doing so. The Company generally uses commercial paper borrowings for general corporate purposes, funding of acquisitions and the repurchases of its common stock.

As of December 31, 2019, the future maturities of long-term debt were as follows:

Letters of Credit and other Guarantees

As of December 31, 2019, the Company had approximately $158.5 million outstanding in letters of credit, surety bonds, and performance and other guarantees with financial institutions, which expire on various dates through 2028. These letters of credit and bonds are primarily issued as security for insurance, warranty and other performance obligations. In general, the Company would only be liable for the amount of these guarantees in the event of default in the performance of its obligations, the probability of which is believed to be remote.

Defined Benefit Plan [Abstract]

Employee Benefit Plans

17. 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 $50,031, $46,030 and $43,447 for the years ended December 31, 2019, 2018 and 2017, respectively.

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 on May 9, 2018, 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 of 2018, 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.

The Company’s net unfunded status at December 31, 2019 and 2018 includes net liabilities of $110,944 and $107,740, respectively, relating to the Company’s significant international qualified plans, some in locations where it is not economically advantageous to pre-fund the plans due to local regulations. The majority of the international obligations relate to defined pension plans operated by the Company’s businesses in Germany, Switzerland, and the United Kingdom.

The accumulated benefit obligation for all defined benefit pension plans was $815,257 and $756,194 at December 31, 2019 and 2018, respectively. Pension plans with accumulated benefit obligations in excess of plan assets consist of the following at December 31, 2019 and 2018:

	U.S. Plan											Non-U.S. Plans
	2019		2018			2017		2019		2018		2017		2019		2018		2017		2019		2018		2017
Discount rate	4.35	%	4.2%/3.65%		⁽¹⁾	4.10	%	1.83	%	1.94	%	2.06	%	4.30	%	3.57	%	3.97	%	4.15	%	3.50	%	6.49	%
Average wage increase	4.00	%	4.00	%		4.00	%	2.10	%	2.33	%	2.34	%	4.50	%	4.50	%	4.50	%	na		na		na
Expected return on plan assets	6.80	%	6.8%/7.25%		⁽¹⁾	7.25	%	3.67	%	4.66	%	4.73	%	na		na		na		na		na		na

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 2020. 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, 2019 by $78 and $(76), respectively, and would have a negligible impact on the net post-retirement benefit cost for 2019.

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 plan's long-term investment objective is to generate investment returns that provide adequate assets to meet all benefit obligations in accordance with applicable regulations. The expected return on assets assumption used for pension expense is developed through analysis of historical and forecasted 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:


	2019		2018		Current Target
Equity securities	34	%	36	%	34	%
Fixed income	64	%	55	%	66	%
Real estate and other	2	%	9	%	—	%
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 average rates of return on invested assets of 3.67% in 2019, 4.66% in 2018 and 4.73% in 2017.

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 13 — Financial Instruments) were as follows:


	U.S. Qualified Defined Benefits Plan
	12/31/2019										12/31/2018

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 ("NAV") as a practical expedient depending on the nature of the observable inputs. Collective funds 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 2018 and 2019, due to the following:


	Level 3
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

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
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 and solutions provider delivering innovative equipment and components, consumable supplies, aftermarket parts, software and digital solutions and support services. The Company’s businesses are based primarily in the United States and Europe with manufacturing and other operations throughout the world. The Company operates through five business segments that are structured around similar business models, go-to market strategies and manufacturing practices: Engineered Products, Fueling Solutions, Imaging & Identification, Pumps & Process Solutions and Refrigeration & Food Equipment. For additional information on the Company’s segments, see Note 19 — 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, the fair 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 are 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 15 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 change 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, when some portion but not all of a reporting unit is disposed of or classified as assets held for sale, or when a change in the composition of reporting units occurs for other reasons, such as a change in segments. The Company performs its goodwill impairment test annually in the fourth quarter at the reporting unit level. Concurrent with the timing of the annual impairment test, effective October 1, 2019, the Company changed its management structure which resulted in a change in its operating segments and reporting units. As a result, management tested goodwill for impairment before and after the segment change under the old and new reporting unit structures. Based on its new organizational structure, the Company identified fifteen reporting units for which cash flows are determinable and to which goodwill may be allocated. 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 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 9 — 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. 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, 2019, 2018, or 2017.
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 20 years.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring Accruals 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 may include contractual terminations and asset impairments 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 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 ASC Topic 606, Revenue from Contracts with Customers. Under ASC 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 was recognized when all the following conditions were 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, 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 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 15 — Equity and Cash Incentive Program for additional information related to the Company’s stock-based compensation.
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 it is more likely than not that some portion or all will not be realized. 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 the 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 did 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 made as a result of the Tax Reform Act.
Research and Development Costs [Policy Text Block]	Research and Development CostsResearch and development costs, including qualifying engineering costs, are expensed when incurred and amounted to $140,957 in 2019, $143,033 in 2018 and $130,536 in 2017. These costs as a percent of revenue were 2.0% in 2019, 2.0% in 2018 and 1.9% in 2017.
Advertising [Policy Text Block]	Advertising Costs Advertising costs are expensed when incurred and amounted to $24,609 in 2019, $26,831 in 2018 and $33,369 in 2017.
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 $1.0 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 business interruption 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. As described in Note 19 — Segment Information, the Company realigned into five business segments effective October 1, 2019.
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 June 2016, the FASB issued Accounting Standards Update ("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. In addition, the FASB issued ASU 2019-04, Codification Improvements to Topic 326 which provides clarity on certain aspects of the amendments in ASU 2016-13. The guidance is effective for interim and annual periods for the Company beginning on January 1, 2020. The Company believes that the most notable impact of this ASU will 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. Management does not expect this update to have a material impact to the Company's Consolidated Financial Statements. Recently Adopted Accounting Standards In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections. This ASU amends various SEC paragraphs pursuant to the issuance of SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization. One of the changes in the ASU requires a presentation of changes in stockholders’ equity in the form of a reconciliation, either as a separate financial statement or in the notes to the financial statements, for the current and comparative year-to-date interim periods. The Company presented changes in stockholders' equity as separate financial statements for the current and comparative year-to-date interim periods beginning on January 1, 2019. The additional elements of the ASU did not have a material impact on the Company's Consolidated Financial Statements. This guidance was effective immediately upon issuance. In August 2018, the FASB issued 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 Company early adopted the guidance prospectively beginning on January 1, 2019. The adoption of this ASU did not 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 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 Company adopted this guidance on January 1, 2019. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements. 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. 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. The Company elected this new transition method when it adopted ASU 2016-02 on January 1, 2019. Upon adoption on January 1, 2019, total assets and liabilities increased due to the recording of right-of-use assets and lease liabilities amounting to approximately $163 million. See Note 8 — Leases for further details.
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy	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.
Lessee, Leases	Leases Effective January 1, 2019, the Company adopted Accounting Standard Codification ("ASC") Topic 842, Leases, which requires the recording of operating lease right-of-use assets ("ROU") and operating lease liabilities. Finance leases were not impacted by the adoption of ASC Topic 842, as finance lease liabilities and the corresponding ROU assets were already recorded in the balance sheet under the previous guidance, ASC Topic 840. The Company has operating and finance leases for corporate offices, manufacturing plants, research and development facilities, shared services facilities, vehicle fleets and certain office and manufacturing equipment. Leases with an initial term of 12 months or less are not recorded in the balance sheet. The Company has elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component, thus causing all fixed payments to be capitalized. The Company also elected the package of practical expedients permitted within the new standard, which among other things, allows the Company to carry forward historical lease classification. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as increases in lease payments based on changes in index rates or usage, are not included in the ROU assets or liabilities. These are expensed as incurred and recorded as variable lease expense. The Company determines if an arrangement is a lease at inception of a contract. Operating lease ROU assets are included in other assets and deferred charges and operating lease liabilities are included in other accrued expenses and other liabilities in the Consolidated Balance Sheet. Finance lease ROU assets are included in property and equipment, and the related lease liabilities are included in other accrued expenses and other liabilities in the Consolidated Balance Sheet. ROU assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the net present value of fixed lease payments over the lease term. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. ROU assets also include any advance lease payments made and exclude lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Fixed operating lease expense and finance lease depreciation expense are recognized on a straight-line basis over the lease term.

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, in 2018, 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 Products segment. In 2019, in connection with the change in segment structure, the Company changed its reporting units which resulted in a reallocation of $40,394 of goodwill from the Engineered Products segment to the Imaging & Identification segment using the relative fair value approach. See Note 19 — Segment Information for further information.

The changes in the carrying value of goodwill by reportable operating segments were as follows:


	Engineered Products		Fueling Solutions		Imaging & Identification		Pumps & Process Solutions		Refrigeration & Food Equipment		Total

During 2019 and 2018, the Company recognized additions of $119,512 and $46,711, respectively, to goodwill as a result of acquisitions as discussed in Note 4 — Acquisitions. During 2019 and 2018, the Company recorded adjustments totaling $0 and $328, respectively, as a result of the finalization of purchase price allocation to assets acquired and liabilities assumed related to acquisitions completed in 2018 and 2017.

During 2019, the Company derecognized $4,739 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, whenever events or circumstances indicate an impairment may have occurred, or when a change in the composition of reporting units occurs for other reasons, such as a change in segments. Concurrent with the timing of the annual impairment test, effective October 1, 2019, the Company changed its management structure which resulted in a change in its operating segments and reporting units. As a result, management tested goodwill for impairment before and after the segment change under the old and new reporting unit structures.

The Company performed its annual goodwill impairment test during the fourth quarter of 2019 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 under the old structure and fifteen reporting units under the new structure, concluding that the fair values of all of its reporting units were substantially in excess of their carrying values. No impairment of goodwill was required. 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 2019 reporting unit valuations ranged from 8.0% to 9.5%.

While the Company believes the assumptions used in the 2019 impairment analysis are reasonable and representative of expected results, actual results may differ from expectations.

The Company adopted ASC Topic 842, Leases as of January 1, 2019, using the transition method per ASU No. 2018-11 issued in July 2018 wherein entities were allowed to initially apply the new leases standard at adoption date. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC Topic 840, Leases, and no retrospective adjustments were made to the comparative periods presented. Adoption of ASC Topic 842 resulted in an increase to total assets and liabilities due to the recording of operating lease ROU assets and operating lease liabilities of approximately $163 million, as of January 1, 2019. The adoption did not materially impact the Company’s Consolidated Statements of Earnings or Cash Flows. See Note 1 — Basis of Presentation for further detail on ROU assets and lease liabilities.

As of December 31, 2019, the Company had non-U.S loss carryforwards of $938.5 million primarily resulting from non-operating activities. The entire balance of the non-U.S. losses as of December 31, 2019 is available to be carried forward, with $72.6 million of these losses expiring during the years 2020 through 2039. The remaining $865.9 million of such losses can be carried forward indefinitely.

The Company has $54.1 million and $62.9 million of state tax loss carryforwards as of December 31, 2019 and 2018, respectively, that are available for use by the Company between 2020 and 2039.

The Company maintains valuation allowances by jurisdiction against the deferred tax assets related to certain of these carryforwards for which it is more likely than not that some portion or all will not be realized.

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 earnings and profits through the year ended December 31, 2017. 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 did 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 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 $15.3 million. The Company is no longer subject to examinations of its federal income tax returns through 2015. 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.

Total	$	26,822	$	58,503	$	52,260

Total restructuring charges of $26,822 incurred during the year ended December 31, 2019, were a result of restructuring programs initiated in 2018 and 2019. Restructuring expense was comprised primarily of broad-based selling, general and administrative expense reduction initiatives and broad-based operational efficiency initiatives focusing on footprint consolidation, operational optimization and IT centralization 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 $8 million in 2020 for these initiatives. Additional programs, beyond the scope of the announced programs may be implemented during 2020 with related restructuring charges.

The $26,822 of restructuring charges incurred during 2019 included the following programs:

•The Engineered Products segment recorded $3,155 of restructuring charges related to programs across the segment focused on headcount reductions and facility restructuring costs.

•The Fueling Solutions segment recorded $4,943 of restructuring charges principally related to headcount reductions.

•The Imaging & Identification segment recorded $6,426 of restructuring charges principally related to headcount reductions.

•The Pumps & Process Solutions segment recorded $5,666 of restructuring charges principally related to headcount reductions.

•The Refrigeration & Food Equipment segment recorded $3,671, of restructuring charges primarily due to headcount reductions and facility restructuring costs.

•Corporate recorded $2,961 of restructuring charges primarily related to headcount reductions.

Restructuring expenses incurred in 2018 and 2017 also included headcount reduction, targeted facility consolidations at certain businesses and actions taken to optimize the Company's cost structure.

The following table is a reconciliation of the share amounts used in computing earnings per share:


	Years Ended December 31,
	2019	2018	2017
Weighted average shares outstanding - Basic	145,198,000	149,874,000	155,685,000
Dilutive effect of assumed exercise of SARs and vesting of performance shares and RSUs	1,794,000	2,259,000	2,059,000
Weighted average shares outstanding - Diluted	146,992,000	152,133,000	157,744,000

Diluted earnings per share amounts are computed using the weighted average number of common shares outstanding and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of SARs and vesting of performance shares and RSUs, as determined using the treasury stock method. For the years ended December 31, 2019, 2018 and 2017, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 28,096, 1,382 and 79,756, respectively.

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 and solutions provider delivering innovative equipment and components, consumable supplies, aftermarket parts, software and digital solutions and support services. The Company’s businesses are based primarily in the United States and Europe with manufacturing and other operations throughout the world. The Company operates through five business segments that are structured around similar business models, go-to market strategies and manufacturing practices: Engineered Products, Fueling Solutions, Imaging & Identification, Pumps & Process Solutions and Refrigeration & Food Equipment. For additional information on the Company’s segments, see Note 19 — 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, the fair 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 are 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 15 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 change 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, when some portion but not all of a reporting unit is disposed of or classified as assets held for sale, or when a change in the composition of reporting units occurs for other reasons, such as a change in segments. The Company performs its goodwill impairment test annually in the fourth quarter at the reporting unit level. Concurrent with the timing of the annual impairment test, effective October 1, 2019, the Company changed its management structure which resulted in a change in its operating segments and reporting units. As a result, management tested goodwill for impairment before and after the segment change under the old and new reporting unit structures. Based on its new organizational structure, the Company identified fifteen reporting units for which cash flows are determinable and to which goodwill may be allocated. 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 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 9 — 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. 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, 2019, 2018, or 2017. 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 20 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. Leases Effective January 1, 2019, the Company adopted Accounting Standard Codification ("ASC") Topic 842, Leases, which requires the recording of operating lease right-of-use assets ("ROU") and operating lease liabilities. Finance leases were not impacted by the adoption of ASC Topic 842, as finance lease liabilities and the corresponding ROU assets were already recorded in the balance sheet under the previous guidance, ASC Topic 840. The Company has operating and finance leases for corporate offices, manufacturing plants, research and development facilities, shared services facilities, vehicle fleets and certain office and manufacturing equipment. Leases with an initial term of 12 months or less are not recorded in the balance sheet. The Company has elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component, thus causing all fixed payments to be capitalized. The Company also elected the package of practical expedients permitted within the new standard, which among other things, allows the Company to carry forward historical lease classification. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as increases in lease payments based on changes in index rates or usage, are not included in the ROU assets or liabilities. These are expensed as incurred and recorded as variable lease expense. The Company determines if an arrangement is a lease at inception of a contract. Operating lease ROU assets are included in other assets and deferred charges and operating lease liabilities are included in other accrued expenses and other liabilities in the Consolidated Balance Sheet. Finance lease ROU assets are included in property and equipment, and the related lease liabilities are included in other accrued expenses and other liabilities in the Consolidated Balance Sheet. ROU assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the net present value of fixed lease payments over the lease term. The lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. ROU assets also include any advance lease payments made and exclude lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Fixed operating lease expense and finance lease depreciation expense are recognized on a straight-line basis over the lease term. Restructuring Accruals 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 may include contractual terminations and asset impairments 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 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 ASC Topic 606, Revenue from Contracts with Customers. Under ASC 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 was recognized when all the following conditions were 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 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 15 — 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 it is more likely than not that some portion or all will not be realized. 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 the 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 did 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 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 $140,957 in 2019, $143,033 in 2018 and $130,536 in 2017. These costs as a percent of revenue were 2.0% in 2019, 2.0% in 2018 and 1.9% in 2017. Advertising Costs Advertising costs are expensed when incurred and amounted to $24,609 in 2019, $26,831 in 2018 and $33,369 in 2017. 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 $1.0 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 business interruption 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. As described in Note 19 — Segment Information, the Company realigned into five business segments effective October 1, 2019. 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 June 2016, the FASB issued Accounting Standards Update ("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. In addition, the FASB issued ASU 2019-04, Codification Improvements to Topic 326 which provides clarity on certain aspects of the amendments in ASU 2016-13. The guidance is effective for interim and annual periods for the Company beginning on January 1, 2020. The Company believes that the most notable impact of this ASU will 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. Management does not expect this update to have a material impact to the Company's Consolidated Financial Statements. Recently Adopted Accounting Standards In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections. This ASU amends various SEC paragraphs pursuant to the issuance of SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization. One of the changes in the ASU requires a presentation of changes in stockholders’ equity in the form of a reconciliation, either as a separate financial statement or in the notes to the financial statements, for the current and comparative year-to-date interim periods. The Company presented changes in stockholders' equity as separate financial statements for the current and comparative year-to-date interim periods beginning on January 1, 2019. The additional elements of the ASU did not have a material impact on the Company's Consolidated Financial Statements. This guidance was effective immediately upon issuance. In August 2018, the FASB issued 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 Company early adopted the guidance prospectively beginning on January 1, 2019. The adoption of this ASU did not 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 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 Company adopted this guidance on January 1, 2019. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements. 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. 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. The Company elected this new transition method when it adopted ASU 2016-02 on January 1, 2019. Upon adoption on January 1, 2019, total assets and liabilities increased due to the recording of right-of-use assets and lease liabilities amounting to approximately $163 million. See Note 8 — Leases for further details.

Revenue from Contract with Customer [Abstract]

3. Revenue

Revenue from contracts with customers

Effective January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers, 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.

Under ASC 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 segments and geographic location, as it best depicts the nature and amount of the Company's revenue.

See Note 19 — Segment Information for revenue by segment and geographic location.

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 standalone 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, 2019, we estimated that $80.4 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 50% of our unsatisfied (or partially unsatisfied) performance obligations as revenue in 2020, with the remaining balance to be recognized in 2021 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:


	12/31/2019		12/31/2018		At Adoption

Contract assets	$	14,894	$	9,330	$	11,932
Contract liabilities - current	44,001		36,461		48,268
Contract liabilities - non-current	9,121		9,382		9,916

The revenue recognized during 2019 and 2018 that was included in the contract liability at the beginning of the respective periods amounted to $31,283 and $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 ASC Topic 606, effective January 1, 2018, using the modified retrospective method applying ASC 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 ASC Topic 605. The Company's accounting policy has been updated to align with ASC 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 are 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 ASC Topic 606.

Under ASC 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 ASC 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 ASC Topic 606 under the modified retrospective method.

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, 2019 and 2018, the Company issued 258,551,748 and 257,822,352 shares of common stock and had 114,249,432 and 112,905,810 treasury shares, held at cost, respectively. Share Repurchases The Company's prior January 2015 share repurchase authorization expired on January 9, 2018. From January 1 to January 9, 2018, the Company repurchased 440,608 shares of common stock at a total cost of $44,977 or $102.08 per share. 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 million 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. During the year ended December 31, 2019 and 2018, under the February 2018 authorization, exclusive of the ASR Agreement, the Company repurchased 1,343,622 and 1,753,768 shares of common stock at a total cost of $143,280 and $150,000 or $106.64 and $85.53 per share, respectively. As of December 31, 2019, 8,360,044 shares remain authorized for repurchase under the February 2018 share repurchase authorization.

Segment Reporting [Abstract]

Segment Information

19. Segment Information

Effective October 1, 2019, Dover transitioned from a three-segment to a five-segment structure as a result of a change to its management structure and operating model. The Company's businesses are structured around similar business models, go-to market strategies and manufacturing practices which increases management efficiency and better aligns Dover's operations with its strategic initiatives and capital allocation priorities, and provide greater transparency about performance. 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, which is composed of Dover's executive leadership team, in making resource allocation decisions and evaluating performance.

The Company categorizes its operating companies into five reportable segments based on how the CODM analyze performance, allocate capital and make strategic and operational decisions. The five reportable segments are as follows:

•Engineered Products segment is a provider of a wide range of products, software and services that have broad customer applications across a number of markets, including aftermarket vehicle service, solid waste handling, industrial automation, aerospace and defense, industrial winch and hoist, and fluid dispensing.

•Fueling Solutions segment is focused on providing components, equipment and software and service solutions enabling safe transport of fuels and other hazardous fluids along the supply chain, as well as the safe and efficient operation of retail fueling and vehicle wash establishments.

•Imaging & Identification segment supplies precision marking and coding, product traceability and digital textile printing equipment, as well as related consumables, software and services.

•Pumps & Process Solutions segment manufactures specialty pumps, fluid handling components, plastics and polymer processing equipment, and highly engineered components for rotating and reciprocating machines.

•Refrigeration & Food Equipment segment is a provider of innovative and energy-efficient equipment and systems that serve the commercial refrigeration, heating and cooling and food equipment markets.

Segment financial information and a reconciliation of segment results to consolidated results follows:

The majority of revenue from our Engineered Products, Fueling Systems, Imaging & Identification. Pumps & Process Solutions, and Refrigeration & Food Equipment segments is generated from sales to customers within the United States, Europe and Asia. Each segment also generates revenue across the other geographies, with no significant concentration of any segment’s remaining revenue.

Revenue is attributed to regions based on the location of the Company’s customer, which in some instances is an intermediary and not necessarily the end user. Long-lived assets are comprised of net property, plant and equipment. The Company’s businesses are based primarily in the United States, Europe and Asia. The Company’s businesses serve thousands of customers, none of which accounted for more than 10% of consolidated revenue.

Pro forma results of operations

The following unaudited pro forma results of operations reflect the 2019 acquisitions as if they had occurred on January 1, 2018 and the 2018 acquisitions as if they had occurred on January 1, 2017. 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, 2019. These adjustments were not material in 2019 and 2018. The supplemental pro forma earnings for the 2018 period were similarly adjusted for 2018 acquisitions charges as if incurred at the beginning of 2017. The 2019 and 2018 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 2019 and 2018 acquisitions.

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

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 the 2018 accelerated share repurchase program. See Note 21 — 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.

Acquisitions

4. Acquisitions

2019

During the year ended December 31, 2019, the Company acquired three businesses in separate transactions for total consideration of $216,398, net of cash acquired and including contingent consideration. These businesses were acquired to complement and expand upon existing operations within the Fueling Solutions and Pumps & Process Solutions segments. The goodwill recorded as a result of these acquisitions represents the economic benefits expected to be derived from product line expansions and operational synergies. The goodwill is deductible for U.S. income tax purposes for these acquisitions.

On May 7, 2019, the Company acquired the assets of the All-Flo Pump Company, Limited business ("All-Flo"), a growing manufacturer of specialty pumps for $39,954. The All-Flo acquisition strengthens Dover's position in the growing market for air-operated double-diaphragm pumps within the Pumps & Process Solutions segment.
