Accounting Policies [Abstract]
Significant Accounting Policies	1. Significant Accounting Policies Basis of Consolidation The accompanying consolidated financial statements reflect the results of operations, financial position and cash flows of AMETEK, Inc. (the “Company”), and include the accounts of the Company and subsidiaries, after elimination of all intercompany transactions in the consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and assumptions. Cash Equivalents, Securities and Other Investments All highly liquid investments with maturities of three months or less Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of specific customers to meet their financial obligations to the Company. A specific allowance for doubtful accounts is recorded against the amount due from these customers. For all other customers, the Company recognizes allowance for doubtful accounts based on the length of time specific receivables are past due based on its historical experience. Bad debt expense was $2.8 million in 2019, $1.7 million in 2018 and $2.8 million in 2017. Inventories The Company uses the first-in, first-out last-in, first-out Business Combinations The Company allocates the purchase price of an acquired company, including when applicable, the acquisition date fair value of contingent consideration between tangible and intangible assets acquired and liabilities assumed from the acquired business based on their estimated fair values, with the residual of the purchase price recorded as goodwill. The results of operations of the acquired business are included in the Company’s operating results from the date of acquisition. Property, Plant and Equipment Property, plant and equipment are stated at cost. Expenditures for additions to plant facilities, or that extend their useful lives, are capitalized. The cost of minor tools, jigs and dies, and maintenance and repairs is charged to expense as incurred. Depreciation of plant and equipment is calculated principally on a straight-line three five Goodwill and Other Intangible Assets Goodwill and other intangible assets with indefinite lives, primarily trademarks and trade names, are not amortized; rather, they are tested for impairment at least annually. The Company identifies its reporting units at the component level, which is one level below its operating segments. Generally, goodwill arises from acquisitions of specific operating companies and is assigned to the reporting unit in which the operating company resides. The Company’s reporting units are divisions that are one level below its operating segments and for which discrete financial information is prepared and regularly reviewed by segment management. The Company principally relies on a discounted cash flow analysis to determine the fair value of each reporting unit, which considers forecasted cash flows discounted at an appropriate discount rate. The Company believes that market participants would use a discounted cash flow analysis to determine the fair value of its reporting units in a sale transaction. The annual goodwill impairment test requires the Company to make several assumptions and estimates concerning future levels of revenue growth, operating margins, depreciation, amortization and working capital requirements, which are based on the Company’s long-range plan and are considered level 3 inputs. The Company’s long-range plan is updated as part of its annual planning process and is reviewed and approved by management. The discount rate is an estimate of the overall after-tax The impairment test for indefinite-lived intangibles other than goodwill (primarily trademarks and trade names) consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of its indefinite-lived intangibles using the relief from royalty method using level 3 inputs for revenue growth rates and royalty rates. The fair value derived from the relief from royalty method is measured as the discounted cash flow savings realized from owning such trademarks and trade names and not having to pay a royalty for their use. The Company completed its required annual impairment tests in the fourth quarter of 2019, 2018 and 2017 and determined that the carrying values of the Company’s goodwill were not impaired. The Company completed its required annual impairment tests in the fourth quarter of 2019, 2018 and 2017 and determined that the carrying values of the Company’s other intangible assets with indefinite lives were not impaired. Other intangible assets with finite lives are evaluated for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of other intangible assets with finite lives is considered impaired when the total projected undiscounted cash flows from the asset group are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of those assets. Fair value is determined primarily using present value techniques based on projected cash flows from the asset group. Intangible assets, other than goodwill, with definite lives are amortized over their estimated useful lives. Patents and technology are being amortized over useful lives of five five Financial Instruments and Foreign Currency Translation Assets and liabilities of foreign operations are translated using exchange rates in effect at the balance sheet date and their results of operations are translated using average exchange rates for the year. Certain transactions of the Company and its subsidiaries are denominated in currencies other than their functional currency. Exchange gains and losses from those transactions are included in operating results for the year. The Company makes infrequent use of derivative financial instruments. Forward contracts are entered into from time to time to hedge certain inventory purchases, export sales, debt or foreign currency transactions, thereby minimizing the Company’s exposure to raw material commodity price or foreign currency fluctuation. In instances where transactions are designated as hedges of an underlying item, the gains and losses on those transactions are included in accumulated other comprehensive income within stockholders’ equity to the extent they are effective as hedges. An evaluation of hedge effectiveness is performed by the Company on an ongoing basis and any changes in the hedge are made as appropriate. Revenue Recognition Revenue is derived from sales of products and services. The Company’s products and services are marketed and sold worldwide through two operating groups: EIG and EMG. See Note 15 Descriptive Information about Reportable Segments The majority of the Company’s revenues on product sales were recognized at a point in time when the customer obtains control of the product. The transfer in control of the product to the customer was typically evidenced by one or more of the following: the customer having legal title to the product, the Company’s present right to payment, the customer’s physical possession of the product, the customer accepting the product, or the customer having the benefits of ownership or risk of loss. For a small percentage of sales where title and risk of loss transfers at the point of delivery, the Company recognized revenue upon delivery to the customer, which is the point that control transferred, assuming all other criteria for revenue recognition were met. Research and Development Research and development costs Shipping and Handling Costs Shipping and handling costs are included in Cost of sales and were $66.7 million in 2019, $62.7 million in 2018 and $53.1 million in 2017. Share-Based Compensation The Company expenses the fair value of share-based awards made under its share-based plans in the consolidated financial statements over their requisite service period of the grants. Income Taxes The Company’s process of providing for income taxes and determining the related balance sheet accounts requires management to assess uncertainties, make judgments regarding outcomes and utilize estimates. The Company conducts a broad range of operations around the world and is therefore subject to complex tax regulations in numerous international taxing jurisdictions, resulting at times in tax audits, disputes and potential litigation, the outcome of which is uncertain. Management must make judgments currently about such uncertainties and determine estimates of the Company’s tax assets and liabilities. To the extent the final outcome differs, future adjustments to the Company’s tax assets and liabilities may be necessary. The Company recognizes interest and penalties accrued related to uncertain tax positions in income tax expense. The Company assesses the realizability of its deferred tax assets, taking into consideration the Company’s forecast of future taxable income, available net operating loss carryforwards and available tax planning strategies that could be implemented to realize the deferred tax assets. Based on this assessment, management must evaluate the need for, and amount of, valuation allowances against the Company’s deferred tax assets. To the extent facts and circumstances change in the future, adjustments to the valuation allowances may be required. Pensions The Company has U.S. and foreign defined benefit and defined contribution pension plans. The most significant elements in determining the Company’s pension income or expense are the assumed pension liability discount rate and the expected return on plan assets. All unrecognized prior service costs, remaining transition obligations or assets and actuarial gains and losses have been recognized, net of tax effects, as a charge to accumulated other comprehensive income in stockholders’ equity and will be amortized as a component of net periodic pension cost. The Company uses a measurement date of December 31 (its fiscal year end) for its U.S. and foreign defined benefit plans. Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding stock options and restricted stock grants). The number of weighted average shares used in the calculation of basic earnings per share and diluted earnings per share was as follows for the years ended December 31: 2019 2018 2017 (In thousands) Weighted average shares: Basic shares 227,759 230,823 230,229 Equity-based compensation plans 1,636 1,889 1,616 Diluted shares 229,395 232,712 231,845

Revenue from Contract with Customer [Abstract]
Revenue	3. Revenues The majority of the Company’s revenues on product sales are recognized at a point in time when the customer obtains control of the product. The Company determined that revenues from certain of its customer contracts met the criteria of satisfying its performance obligations over time, primarily in the areas of the manufacture of custom-made equipment and for service repairs of customer-owned equipment. Recognizing revenue over time for custom-manufactured equipment is based on the Company’s judgment that, in certain contracts, the product does not have an alternative use and the Company has an enforceable right to payment for performance completed to date. The Company recognizes incremental cost of obtaining contracts as an expense when incurred if the amortization period of the contract cost assets that the Company would have otherwise recognized is one year or less. These costs are included in Selling, general and administrative expenses in the consolidated statement of income. The determination of the revenue to be recognized in each period for performance obligations satisfied over time is based on the input method. The Company recognizes revenue over time as it performs on these contracts because the transfer of control to the customer occurs over time. Revenue is recognized based on the extent of progress towards completion of the performance obligation. The Company generally uses the total cost-to-cost cost-to-cost Performance obligations also include post-delivery service, installation and training. Post-delivery service revenues are recognized over the contract term. Installation and training revenues are recognized over the period the service is provided. Warranty terms in customer contracts can also be considered separate performance obligations if the warranty provides services beyond assurance that a product complies with agreed-upon specification or if a warranty can be purchased separately. The Company does not incur significant obligations for customer returns and refunds. The Company has certain contracts with variable consideration in the form of volume discounts, rebates and early payment options, which may affect the transaction price used as the basis for revenue recognition. In these contracts, the amount of the variable consideration is allocated among the various performance obligations in the customer contract based on the relative standalone selling price of each performance obligation to the total standalone value of all the performance obligations. Payment terms generally begin upon shipment of the product. The Company does have contracts with multiple billing terms that are all due within one year from when the product is delivered. No significant financing component exists. Payment terms are generally 30-60 The outstanding contract asset and (liability) accounts were as follows: 2019 2018 (In thousands) Contract assets – January 1 $ 58,266 $ 32,658 Contract assets – December 31 73,039 58,266 Change in contract assets – increase 14,773 25,608 Contract liabilities – January 1 146,162 117,058 Contract liabilities – December 31 167,306 146,162 Change in contract liabilities – increase (21,144 ) (29,104 ) Net change $ (6,371 ) $ (3,496 ) The net change in 2019 and 2018 was primarily driven by the receipt of advance payments from customers relating to 2019 and 2018 acquisitions exceeding the recognition of revenue as performance obligations were satisfied prior to billing. For the years ended December 31, 2019 and 2018, the Company recognized revenue of $130 million and $97 million, respectively, that was previously included in the beginning balance of contract liabilities. Contract assets are reported as a component of Other current assets in the consolidated balance sheet. At December 31, 2019 and 2018, $10.6 million and $8.9 million, respectively, of Customer advanced payments (contract liabilities) were recorded in Other long-term liabilities in the consolidated balance sheet. Applying the practical expedient available under ASC 606, the remaining performance obligations exceeding one year as of December 31, 2019 and 2018 were $233.3 million and $187.2 million, respectively. Remaining performance obligations represent the transaction price of firm, noncancelable orders, with expected delivery dates to customers greater than one year from the balance sheet date, for which the performance obligation is unsatisfied or partially unsatisfied. These performance obligations will be substantially satisfied within two to three years.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. See Note 6 for discussion of acquisition date fair value of contingent payment liability. The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the Company’s assets that are measured at fair value on a recurring basis, consistent with the fair value hierarchy, at December 31: 2019 2018 Fair Value Fair Value (In thousands) Mutual fund investments $ 8,390 $ 7,655 The fair value of mutual fund investments, which are valued as level 1 investments, was based on quoted market prices. The mutual fund investments are shown as a component of long-term assets in the consolidated balance sheet. For the years ended December 31, 2019 and 2018, gains and losses on the investments noted above were not significant. No transfers between level 1 and level 2 investments occurred during the years ended December 31, 2019 and 2018. Financial Instruments Cash, cash equivalents and mutual fund investments are recorded at fair value at December 31, 2019 and 2018 in the accompanying consolidated balance sheet. The following table provides the estimated fair values of the Company’s financial instrument liabilities, for which fair value is measured for disclosure purposes only, compared to the recorded amounts at December 31: 2019 2018 Recorded Fair Value Recorded Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,382,041 ) $ (2,531,549 ) $ (2,378,809 ) $ (2,368,676 ) The fair value of short-term Foreign Currency At December 31, 2019, the Company had a Canadian dollar forward contract for a total notional value of 14.0 million Canadian dollars ($0.1 million fair value unrealized gain at December 31, 2019) outstanding. At December 31, 2018, the Company had a Canadian dollar forward contract for a total notional value of 30.0 million Canadian dollars ($1.0 million fair value unrealized loss at December 31, 2018) outstanding. At December 31, 2017, the Company had a Canadian dollar forward contract for a total notional value of 83.0 million Canadian dollars ($1.5 million fair value unrealized gain at December 31, 2017) which settled in the first quarter of 2018. For the year ended December 31, 2019 and 2018, realized gains and losses on foreign currency forward contracts were not significant. The Company does not typically designate its foreign currency forward contracts as accounting hedges.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedging Activities	5. Hedging Activities The Company has designated certain foreign-currency-denominated long-term borrowings as hedges of the net investment in certain foreign operations. As of December 31, 2019, and 2018, these net investment hedges included British-pound- and Euro-denominated long-term debt. These borrowings were designed to create net investment hedges in each of the designated foreign subsidiaries. The Company designated the British-pound- and Euro-denominated loans referred to above as hedging instruments to offset translation gains or losses on the net investment due to changes in the British pound and Euro exchange rates. These net investment hedges are evidenced by management’s contemporaneous documentation supporting the hedge designation. Any gain or loss on the hedging instruments (the debt) following hedge designation is reported in accumulated other comprehensive income in the same manner as the translation adjustment on the hedged investment based on changes in the spot rate, which is used to measure hedge effectiveness. At December 31, 2019 and 2018, the Company had $404.7 million and $389.2 million, respectively, of British-pound-denominated loans, which were designated as a hedge against the net investment in British pound functional currency foreign subsidiaries. At December 31, 2019 and 2018, the Company had $645.6 million and $658.7 million, respectively, in Euro-denominated loans, which were designated as a hedge against the net investment in Euro functional currency foreign subsidiaries. As a result of the British-pound- and Euro-denominated loans being designated and 100% effective as net investment hedges, $2.4 million of pre-tax pre-tax

The Tax Act, which is also commonly referred to as “U.S. tax reform,” significantly changes U.S. corporate income tax laws by, among other things, reducing the U.S. corporate income tax rate to 21% starting in 2018 and creating a territorial tax system with a one-time $185.8 million benefit resulting from the remeasurement of the Company’s net deferred tax liabilities in the U.S. based on the new lower corporate income tax rate and $94.2 million expense mostly relating to the one-time non-U.S. During 2018 the Company finalized the calculations of the Tax Act transitional tax items and reported a favorable $11.8 million tax benefit of which $10.4 million relates to the one-time one-time non-U.S. million, of which none is payable within the next twelve The Company has evaluated the impact of the global intangible low-taxed As a result of the one-time million in previously taxed income (“PTI”) as of December 31, 2019 which can be repatriated without incremental U.S. Federal tax. The Company intends to reinvest its earnings indefinitely in operations outside the United States except to the extent of the PTI. There has been no provision for U.S. deferred income taxes for the undistributed earnings over PTI of approximately $714.0 million and $828.0 million at December 31, 2019 and 2018 respectively because determination of the amount of the unrecognized deferred income tax liability on these undistributed earnings is not practicable. As of December 31, 2019, and 2018, the Company recorded deferred income taxes totaling $13.0 million and $12.6 million respectively in state income and foreign withholding taxes expected to be incurred when the cash amounts related to the mandatory tax are ultimately repatriated to the U.S. The Company is acquisitive and at times acquires entities with tax attributes (net operating losses or tax credits) that carry over to post-acquisition tax periods of the Company. At December 31, 2019, the Company had tax effected benefits of $41.8 million related to net operating loss carryforwards, which will be available to offset future income taxes payable, subject to certain annual or other limitations based on foreign and U.S. tax laws. This amount includes net operating loss carryforwards of $23.4 million for federal income tax purposes with no valuation allowance, $15.7 million for state income tax purposes with no valuation allowance and $2.7 million for foreign income tax purposes with a valuation allowance of $2.6 million. These net operating loss carryforwards, if not used, will expire between 2020 and 2039. At December 31, 2019, the Company had tax effected benefits of $8.2 million related to tax credit carryforwards, which will be available to offset future income taxes payable, subject to certain annual or other limitations based on foreign and U.S. tax laws. This amount includes tax credit carryforwards of $2.1 million for federal income tax purposes with a valuation allowance of $1.3 million, $6.1 million for state income tax purposes with a valuation allowance of $1.9 million, and no remaining credit carryforwards for foreign income tax purposes. These tax credit carryforwards, if not used, will expire between 2020 and 2039. The Company maintains a valuation allowance to reduce certain deferred tax assets to amounts that are more likely than not to be realized. This allowance primarily relates to the deferred tax assets established for state non-deductible foreign loss es and s tate loss non-deductible At December 31, 2019, the Company had gross unrecognized tax benefits of $109.1 million, of which $65.9 million, if recognized, would impact the effective tax rate. At December 31, 2018, the Company had gross unrecognized tax benefits of $119.3 million, of which $73.1 million, if recognized, would impact the effective tax rate. At December 31, 2019 and 2018, the Company reported $14.2 million and $14.0 million, respectively, related to interest and penalty exposure as accrued income tax expense in the consolidated balance sheet. During 2019, 2018 and 2017, the Company recognized a net expense of $0.2 million, $8.9 million and $0.9 million, respectively, for interest and penalties related to uncertain tax positions in the consolidated statement of income as a component of income tax expense. Approximately 70% of the Company’s overall tax liability is incurred in the United States. The Company files income tax returns in various other state and foreign tax jurisdictions, in some cases for multiple legal entities per jurisdiction. Generally, the Company has open tax years subject to tax audit on average of between three and six years in these jurisdictions. At December 31, 2019, there were no tax years currently under examination by the Internal Revenue Service (“IRS”) related to the U.S. consolidated tax group, although a separate examination of a pre-acquisition During 2019, the Company added $25.4 million of tax, interest and penalties related to identified uncertain tax positions and reversed $35.4 million of tax and interest related to statute expirations and settlement of prior uncertain positions. During 2018, the Company added $81.6 million of tax, interest and penalties related to identified uncertain tax positions and reversed $18.4 million of tax and interest related to statute expirations and settlement of prior uncertain positions. The following is a reconciliation of the liability for uncertain tax positions at December 31: 2019 2018 2017 (In millions) Balance at the beginning of the year $ 119.3 $ 60.3 $ 57.9 Additions for tax positions related to the current year 17.5 21.8 10.0 Additions for tax positions of prior years 2.8 53.5 3.1 Reductions for tax positions of prior years (1.3 ) (3.9 ) (2.8 ) Reductions related to settlements with taxing authorities (0.9 ) — — Reductions due to statute expirations (28.3 ) (12.4 ) (7.9 ) Balance at the end of the year $ 109.1 $ 119.3 $ 60.3 In 2019, the additions above primarily reflect the increase in tax liabilities for uncertain tax positions related to certain higher transfer pricing risks for hard to value intangible assets. The reductions above primarily relate to statute expirations. In 2018 , the additions above primarily reflect the increase in tax liabilities for uncertain tax positions related to certain higher transfer pricing risks for hard to value intangible assets that may more likely be asserted following U.S. tax reform as taxpayer react and adapt to new tax planning initiatives. The reductions above primarily relate to statute expirations. At December 31, 2019, tax, interest and penalties of $121.8 million were classified as a noncurrent liability. The net change in uncertain tax positions for the year ended December 31, 2019 resulted in a decrease to income tax expense of $10.0 million, which reflects the decrease of $10.2 million in gross uncertain tax positions less offsetting benefits reported as decreases to deferred tax liabilities or increases in long-term taxes receivable.

Share-Based Compensation	11. Share-Based Compensation Under the terms of the Company’s stockholder-approved share-based plans, performance restricted stock units (“PRSUs”), incentive and non-qualified one-fourth one-third four years after the grant date (cliff vesting) and is subject to accelerated vesting due to certain events, including doubling of the grant price of the Company’s common stock as of the close of business during any five consecutive trading days. one-third non-employee In March 2019, the Company granted PRSUs to officers and certain key management-level employees an aggregate target award of approximately 102,000 shares of its common stock. The PRSUs vest over a period up to three years from the grant date based on continuous service, with the number of shares earned (0% to 200% of the target award) depending upon the extent to which the Company achieves certain financial and market performance targets measured over the period from January 1, 2019 through December 31, 2021. Half of the PRSUs were valued in a manner similar to restricted stock as the financial targets are based on the Company’s operating results. The grant date fair value of these PRSUs are recognized as compensation expense over the vesting period based on the number of awards expected to vest at each reporting date. The other half of the PRSUs were valued using a Monte Carlo model as the performance target is related to the Company’s total shareholder return compared to a group of peer companies, which represents a market condition. The Company recognizes the grant date fair value of these awards as compensation expense ratably over the vesting period. The Company issues previously unissued shares when stock options are exercised, and shares are issued from treasury stock upon the award of restricted stock. Share Based Compensation Expense The Company measures and records compensation expense related to all stock awards by recognizing the grant date fair value of the awards over their requisite service periods in the financial statements. For grants under any of the Company’s plans that are subject to graded vesting based on a service condition, the Company recognizes expense on a straight-line basis over the requisite service period for the entire award. Total share-based compensation expense was as follows for the years ended December 31: 2019 2018 2017 (In thousands) Stock option expense $ 12,810 $ 11,390 $ 9,895 Restricted stock expense 16,169 14,400 15,196 PRSU expense 11,415 1,525 — Total pre-tax $ 40,394 $ 27,315 $ 25,091 Pre-tax pre-tax Stock Options The fair value of each stock option grant is estimated on the date of grant using a Black-Scholes-Merton 2019 2018 2017 Expected volatility 19.1 % 17.3 % 18.0 % Expected term (years) 5.0 5.0 5.0 Risk-free interest rate 2.25 % 2.81 % 1.94 % Expected dividend yield 0.66 % 0.76 % 0.60 % Black-Scholes-Merton fair value per stock option granted $ 16.85 $ 14.12 $ 11.05 Expected volatility is based on the historical volatility of the Company’s stock over the stock options’ expected term. The Company used historical exercise data to estimate the stock options’ expected term, which represents the period of time that the stock options granted are expected to be outstanding. Management anticipates that the future stock option holding periods will be similar to the historical stock option holding periods. The risk-free interest rate for periods within the expected term of the stock option is based on the U.S. Treasury yield curve at the time of grant. The expected dividend yield is calculated by dividing the Company’s annual dividend, based on the most recent quarterly dividend rate, by the Company’s closing common stock price on the grant date. Compensation expense recognized for all share-based awards is net of estimated forfeitures. The Company’s estimated forfeiture rates are based on its historical experience.

Upon the grant of restricted stock, the fair value of the restricted shares (unearned compensation) at the grant date is charged as a reduction of capital in excess of par value in the Company’s consolidated balance sheet and is amortized to expense on a straight-line basis over the vesting period, which is the same as the calculated derived service period as determined on the grant The following is a summary of the Company’s nonvested restricted stock activity and related information for the year ended December 31, 2019: Shares Weighted Average Fair Value (In thousands) Nonvested restricted stock outstanding at the beginning of the year 891 $ 58.98 Granted 212 85.81 Vested (456 ) 53.82 Forfeited (86 ) 64.60 Nonvested restricted stock outstanding at the end of the year 561 $ 72.46 The total fair value of restricted stock vested during 2019, 2018 and 2017 was $25.2 pre-tax

Retirement Benefits [Abstract]
Retirement Plans and Other Postretirement Benefits	12. Retirement Plans and Other Postretirement Benefits Retirement and Pension Plans The Company sponsors several retirement and pension plans covering eligible salaried and hourly employees. The plans generally provide benefits based on participants’ years of service and/or compensation. The following is a brief description of the Company’s retirement and pension plans. The Company maintains contributory and noncontributory defined benefit pension plans. Benefits for eligible salaried and hourly employees under all defined benefit plans are funded through trusts established in conjunction with the plans. The Company’s funding policy with respect to its defined benefit plans is to contribute amounts that provide for benefits based on actuarial calculations and the applicable requirements of U.S. federal and local foreign laws. The Company estimates that it will make both required and discretionary cash contributions of approximately $3 million to $6 million to its worldwide defined benefit pension plans in 2020. The Company uses a measurement date of December 31 (its fiscal year end) for its U.S. and foreign defined benefit pension plans. The Company sponsors a 401(k) retirement and savings plan for eligible U.S. employees. Participants in the retirement and savings plan may contribute a specified portion of their compensation on a pre-tax The Company’s retirement and savings plan has a defined contribution retirement feature pre-established salary pre-established The Company has nonqualified unfunded retirement plans for its Directors and certain retired employees. It also provides supplemental retirement benefits, through contractual arrangements and/or a Supplemental Executive Retirement Plan (“SERP”) covering certain current and former executives of the Company. These supplemental benefits are designed to compensate the executive for retirement benefits that would have been provided under the Company’s primary retirement plan, except for statutory limitations on compensation that must be taken into account under those plans. The projected benefit obligations of the SERP and the contracts will primarily be funded by a grant of shares of the Company’s common stock upon retirement or termination of the executive. The Company is providing for these obligations by charges to earnings over the applicable periods.

For U.S. equity securities and global equity securities not traded on an active exchange, or if the closing price is not available, the trustee obtains indicative quotes from a pricing vendor, broker or investment manager. These securities are categorized as level 2 if the custodian obtains corroborated quotes from a pricing vendor. Additionally, some U.S. equity securities and global equity securities are public investment vehicles valued using the Net Asset Value (“NAV”) provided by the fund manager. The NAV is the total value of the fund divided by the number of shares outstanding. Fixed income securities categorized as level 1 are traded on national and international exchanges and are valued at their closing prices on the last trading day of the year and categorized as level 2 if valued by the trustee using pricing models that use verifiable observable market data, bids provided by brokers or dealers or quoted prices of securities with similar characteristics. The expected long-term rate of return on these plan assets was 7.50% in 2019 and 7.50% in 2018. Equity securities included 384,788 shares of AMETEK, Inc. common stock with a market value of $38.4 million (6.2% of total plan investment assets) at December 31, 2019 and 512,565 shares of AMETEK, Inc. common stock with a market value of $34.7 million (6.3% of total plan investment assets) at December 31, 2018. The objectives of the Company’s U.S. defined benefit plans’ investment strategy are to maximize the plans’ funded status and minimize Company contributions and plan expense. Because the goal is to optimize returns over the long term, an investment policy that favors equity holdings has been established. Since there may be periods of time where both equity and mutual fund markets provide poor returns, an allocation to alternative assets may be made to improve the overall portfolio’s diversification and return potential. The Company periodically reviews its asset allocation, taking into consideration plan liabilities, plan benefit payment streams and the investment strategy of the pension plans. The actual asset allocation is monitored frequently relative to the established targets and ranges and is rebalanced when necessary. The target allocations for the U.S. defined benefits plans are approximately 50% equity securities, 20% fixed income securities and 30% other securities and/or cash. The equity portfolio is diversified by market capitalization and style. The equity portfolio also includes international components. The objective of the mutual fund portion of the pension assets is to provide interest rate sensitivity for a portion of the assets and to provide diversification. The mutual fund portfolio is diversified within certain quality and maturity guidelines to minimize the adverse effects of interest rate fluctuations. Certain investments are prohibited and include venture capital, private placements, unregistered or restricted stock, margin trading, commodities, short selling and rights and warrants. Foreign currency futures, options and forward contracts may be used to manage foreign currency exposure. The following is a summary of the fair value of plan assets for foreign defined benefit pe n a 2019 2018 Asset Class Total Level 3 Total Level 3 (In thousands) Life insurance $ 19,298 $ 19,298 $ 18,685 $ 18,685 Total investments 19,298 19,298 18,685 18,685 Investments measured at net asset value 205,049 — 178,116 — Total investments $ 224,347 $ 19,298 $ 196,801 $ 18,685 Life insurance assets are considered level 3 investments as their values are determined by the sponsor using unobservable market data. Alternative investments categorized as level 3 are valued based on unobservable inputs and cannot be corroborated using verifiable observable market data. Investments in level 3 funds are redeemable, however, cash reimbursement may be delayed, or a portion held back until asset finalization. The following is a summary of the changes in the fair value of the foreign plans’ level 3 investments (fair value determined using significant unobservable inputs): Life Insurance (In thousands) Balance, December 31, 2017 $ 21,294 Actual return on assets: Unrealized losses relating to instruments still held at the end of the year (2,609 ) Realized gains (losses) relating to assets sold during the year — Purchases, sales, issuances and settlements, net — Balance, December 31, 2018 18,685 Actual return on assets: Unrealized gains (losses) relating to instruments still held at the end of the year 613 Realized gains (losses) relating to assets sold during the year — Purchases, sales, issuances and settlements, net — Balance, December 31, 2019 $ 19,298 The objective of the Company’s foreign defined benefit plans’ investment strategy is to maximize the long-term rate of return on plan investments, subject to a reasonable level of risk. Liability studies are also performed on a regular basis to provide guidance in setting investment goals with an objective to balance risks against the current and future needs of the plans. The trustees consider the risk associated with the different asset classes, relative to the plans’ liabilities and how this can be affected by diversification, and the relative returns available on equities, mutual fund investments, real estate and cash. Also, the likely volatility of those returns and the cash flow requirements of the plans are considered. It is expected that equities will outperform mutual fund investments over the long term. However, the trustees recognize the fact that mutual fund investments may better match the liabilities for pensioners. Because of the relatively young active employee group covered by the plans and the immature nature of the plans, the trustees have chosen to adopt an asset allocation strategy more heavily weighted toward equity investments. This asset allocation strategy will be reviewed, from time to time, in view of changes in market conditions and in the plans’ liability profile. The target allocations for the foreign defined benefit plans are approximately 22% equity securities, 21% fixed income securities, 51% multi-asset funds and 6% other securities, insurance or cash. The assumption for the expected return on plan assets was developed based on a review of historical investment returns for the investment categories for the defined benefit pension assets. This review also considered current capital market conditions and projected future investment returns. The estimates of future capital market The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for pension plans with a projected benefit obligation in excess of plan assets and pension plans with an accumulated benefit obligation in excess of plan assets were as follows at December 31: U.S. Defined Benefit Pension Plans: Projected Benefit Accumulated Benefit 2019 2018 2019 2018 (In thousands) Benefit obligation $ 7,119 $ 6,928 $ 7,119 $ 6,928 Fair value of plan assets 958 809 958 809 Foreign Defined Benefit Pension Plans: Projected Benefit Fair Value of Assets Accumulated Benefit Fair Value of Assets 2019 2018 2019 2018 (In thousands) Benefit obligation $ 311,783 $ 268,763 $ 309,990 $ 260,301 Fair value of plan assets 224,347 196,801 224,347 196,801 The following table provides the amounts recognized in the consolidated balance sheet at December 31: 2019 2018 (In thousands) Funded status asset (liability): Fair value of plan assets $ 845,979 $ 748,988 Projected benefit obligation (822,297 ) (740,269 ) Funded status at the end of the year $ 23,682 $ 8,719 Amounts recognized in the consolidated balance sheet consisted of: Noncurrent asset for pension benefits (other assets) $ 117,278 $ 86,799 Current liabilities for pension benefits (1,954 ) (1,905 ) Noncurrent liability for pension benefits (91,642 ) (76,175 ) Net amount recognized at the end of the year $ 23,682 $ 8,719 The following table provides the amounts recognized in accumulated other comprehensive income, net of taxes, at December 31: Net amounts recognized: 2019 2018 (In thousands) Net actuarial loss $ 242,696 $ 244,511 Prior service costs 4,189 4,432 Transition asset 6 7 Total recognized $ 246,891 $ 248,950 The following table provides the components of net periodic pension benefit expense (income) for the years ended December 31: 2019 2018 2017 (In thousands) Defined benefit plans: Service cost $ 6,556 $ 6,879 $ 7,138 Interest cost 26,979 25,678 27,424 Expected return on plan assets (52,402 ) (59,325 ) (53,442 ) Settlement 739 — — Amortization of: Net actuarial loss 15,685 12,092 14,591 Prior service costs 484 (49 ) (47 ) Transition asset 1 1 1 Total net periodic benefit income (1,958 ) (14,724 ) (4,335 ) Other plans: Defined contribution plans 32,508 28,829 24,280 Foreign plans and other 9,406 6,185 5,866 Total other plans 41,914 35,014 30,146 Total net pension expense $ 39,956 $ 20,290 $ 25,811 The total net periodic benefit expense (income) is included in Cost of sales, General and administrative expense and Other income and expense in the consolidated statement of income. The estimated amount that will be amortized from accumulated other comprehensive income into net periodic pension benefit expense in 2020 for the net actuarial losses and prior service costs is expected to be approximately $16 million. The following weighted average assumptions were used to determine the above net periodic pension benefit income for the years ended December 31: 2019 2018 2017 U.S. Defined Benefit Pension Plans: Discount rate 4.40 % 4.40 % 4.25 % Expected return on plan assets 7.50 % 7.50 % 7.50 % Rate of compensation increase (where applicable) 3.75 % 3.75 % 3.75 % Foreign Defined Benefit Pension Plans: Discount rate 2.59 % 2.59 % 2.56 % Expected return on plan assets 6.52 % 6.52 % 6.79 % Rate of compensation increase (where applicable) 2.50 % 2.50 % 2.50 % Estimated Future Benefit Payments The estimated future benefit payments for U.S. and foreign plans are as follows: 2020 – – – – – - Postretirement Plans and Postemployment Benefits The Company provides limited postretirement benefits other than pensions for certain retirees and a small number of former employees. Benefits under these arrangements are not funded and are not significant. The Company also provides limited postemployment benefits for certain former or inactive employees after employment but before retirement. Those benefits are not significant in amount. The Company has a deferred compensation plan, which allows employees whose compensation exceeds the statutory IRS limit for retirement benefits to defer a portion of earned bonus compensation. The plan permits deferred amounts to be deemed invested in either, or a combination of, (a) an interest-bearing account, benefits from which are payable out of the general assets of the Company, or (b) the equivalent of a fund which invests in shares of the Company’s common stock on behalf of the employee. The amount deferred under the plan, including income earned, was $19.0 million and $14.4 million at December 31, 2019 and 2018, respectively. Administrative expense for the deferred compensation plan is borne by the Company and is not significant.

Contingencies	13. Contingencies Indemnifications In conjunction with certain acquisition and divestiture transactions, the Company may agree to make payments to compensate or indemnify other parties for possible future unfavorable financial consequences resulting from specified events (e.g., breaches of contract obligations or retention of previously existing environmental, tax or employee liabilities) whose terms range in duration and often are not explicitly defined. Where appropriate, the obligation for such indemnifications is recorded as a liability. Because the amount of these types of indemnifications generally is not specifically stated, the overall maximum amount of the obligation under such indemnifications cannot be reasonably estimated. Further, the Company indemnifies its directors and officers for claims against them in connection with their positions with the Company. Historically, any such costs incurred to settle claims related to these indemnifications have been minimal for the Company. The Company believes that future payments, if any, under all existing indemnification agreements would not have a material impact on its consolidated results of operations, financial position or cash flows. Asbestos Litigation The Company (including its subsidiaries) has been named as a defendant in a number of asbestos-related lawsuits. Certain of these lawsuits relate to a business which was acquired by the Company and do not involve products which were manufactured or sold by the Company. In connection with these lawsuits, the seller of such business has agreed to indemnify the Company against these claims (the “Indemnified Claims”). The Indemnified Claims have been tendered to, and are being defended by, such seller. The seller has met its obligations, in all respects, and the Company does not have any reason to believe such party would fail to fulfill its obligations in the future. To date, no judgments have been rendered against the Company as a result of any asbestos-related lawsuit. The Company believes that it has good and valid defenses to each of these claims and intends to defend them vigorously. Environmental Matters Certain historic processes in the manufacture of products have resulted in environmentally hazardous waste by-products non-AMETEK-owned “non-owned” volume of waste attributed to the Company relative to the amounts attributed to other named PRPs. In eight of these sites, the Company has reached a tentative agreement on the cost of the de minimis settlement to satisfy its obligation and is awaiting executed agreements. The tentatively agreed-to non-de non-owned Total environmental reserves at December 31, 2019 and 2018 were $28.9 million and $27.8 million, respectively, for both non-owned The Company has agreements with other former owners of certain of its acquired businesses, as well as new owners of previously owned businesses. Under certain of the agreements, the former or new owners retained, or assumed and agreed to indemnify the Company against, certain environmental and other liabilities under certain circumstances. The Company and some of these other parties also carry insurance coverage for some environmental matters. To date, these parties have met their obligations in all material respects. The Company believes it has established reserves for the environmental matters described above, which are sufficient to perform all known responsibilities under existing claims and consent orders. The Company has no reason to believe that other third parties would fail to perform their obligations in the future. In the opinion of management, based on presently available information and the Company’s historical experience related to such matters, an adequate provision for probable costs has been made and the ultimate cost resulting from these actions is not expected to materially affect the consolidated results of operations, financial position or cash flows of the Company. The Company has been remediating groundwater contamination for several contaminants, including trichloroethylene (“TCE”), at a formerly owned site in El Cajon, California. Several lawsuits have been filed against the Company alleging damages resulting from the groundwater contamination, including property

Leases and Other Commitments	14. Leases and Other Commitments Leases The Company determines if an arrangement is a lease at inception. This determination generally depends on whether the arrangement conveys to the Company the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset. The Company has lease agreements which include lease and non-lease Operating leases are included in ROU assets, accrued liabilities and other, and other long-term liabilities on our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Operating lease payments are recognized as lease expense on a straight-line basis over the lease term. The Company has no material finance leases. The Company primarily leases buildings (real estate) and automobiles which are classified as operating leases. ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. As an implicit interest rate is not readily determinable in our leases, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease term for all of the Company’s leases includes the non-cancellable Lease payments included in the measurement of the lease liability are comprised of fixed payments, variable payments that depend on an index or rate and amounts probable to be payable under the exercise of the Company option to purchase the underlying asset if reasonably certain. Variable lease payments not dependent on a rate or index associated with the Company’s leases are recognized when the events, activities, or circumstances in the lease agreement on which those payments are assessed are probable. Variable lease payments are presented as operating expense in the Company’s income statement in the same line item as expense arising from fixed lease payments. The Company has commitments under operating leases for certain facilities, vehicles and equipment used in its operations. Our leases have initial lease terms ranging from 2 months to 14 years, with the exception of a single land lease with 64 years remaining. Certain lease agreements contain provisions for future rent increases. The components of lease expense were as follows: 2019 (In thousands) Operating lease cost $ 45,438 Variable lease cost 7,813 Total lease cost $ 53,251 Rental expense was $52.5 million in 2018 and $49.7 Supplemental balance sheet information related to leases was as follows: December 31, 2019 (In thousands) Right of use assets, net $ 179,679 Lease liabilities included in Accrued liabilities and other 43,025 Lease liabilities included in Other long-term liabilities 142,620 Total lease liabilities $ 185,645 Supplemental cash flow information and other information related to leases was as follows for the year ended December 31: 2019 (In thousands) Cash used in operations for operating leases $ 53,266 Right-of-use $ 40,793 Weighted-average remaining lease terms – operating leases (years) 5.93 Weighted-average discount rate – operating leases 3.72 % Maturities of lease liabilities as of December 31, 2019 were as follows: Lease Liability Maturity Analysis Operating Leases (In thousands) 2020 $ 49,432 2021 42,084 2022 34,103 2023 25,879 2024 17,543 Thereafter 38,953 Total lease payments 207,994 Less: imputed interest 22,349 $ 185,645 The Company does not have any leases that have not yet commenced which are significant.

Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation The accompanying consolidated financial statements reflect the results of operations, financial position and cash flows of AMETEK, Inc. (the “Company”), and include the accounts of the Company and subsidiaries, after elimination of all intercompany transactions in the consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and assumptions.
Cash Equivalents, Securities and Other Investments	Cash Equivalents, Securities and Other Investments All highly liquid investments with maturities of three months or less
Accounts Receivable	Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of specific customers to meet their financial obligations to the Company. A specific allowance for doubtful accounts is recorded against the amount due from these customers. For all other customers, the Company recognizes allowance for doubtful accounts based on the length of time specific receivables are past due based on its historical experience. Bad debt expense was $2.8 million in 2019, $1.7 million in 2018 and $2.8 million in 2017.
Inventories	Inventories The Company uses the first-in, first-out last-in, first-out
Business Combinations	Business Combinations The Company allocates the purchase price of an acquired company, including when applicable, the acquisition date fair value of contingent consideration between tangible and intangible assets acquired and liabilities assumed from the acquired business based on their estimated fair values, with the residual of the purchase price recorded as goodwill. The results of operations of the acquired business are included in the Company’s operating results from the date of acquisition.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Expenditures for additions to plant facilities, or that extend their useful lives, are capitalized. The cost of minor tools, jigs and dies, and maintenance and repairs is charged to expense as incurred. Depreciation of plant and equipment is calculated principally on a straight-line three five
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and other intangible assets with indefinite lives, primarily trademarks and trade names, are not amortized; rather, they are tested for impairment at least annually. The Company identifies its reporting units at the component level, which is one level below its operating segments. Generally, goodwill arises from acquisitions of specific operating companies and is assigned to the reporting unit in which the operating company resides. The Company’s reporting units are divisions that are one level below its operating segments and for which discrete financial information is prepared and regularly reviewed by segment management. The Company principally relies on a discounted cash flow analysis to determine the fair value of each reporting unit, which considers forecasted cash flows discounted at an appropriate discount rate. The Company believes that market participants would use a discounted cash flow analysis to determine the fair value of its reporting units in a sale transaction. The annual goodwill impairment test requires the Company to make several assumptions and estimates concerning future levels of revenue growth, operating margins, depreciation, amortization and working capital requirements, which are based on the Company’s long-range plan and are considered level 3 inputs. The Company’s long-range plan is updated as part of its annual planning process and is reviewed and approved by management. The discount rate is an estimate of the overall after-tax The impairment test for indefinite-lived intangibles other than goodwill (primarily trademarks and trade names) consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of its indefinite-lived intangibles using the relief from royalty method using level 3 inputs for revenue growth rates and royalty rates. The fair value derived from the relief from royalty method is measured as the discounted cash flow savings realized from owning such trademarks and trade names and not having to pay a royalty for their use. The Company completed its required annual impairment tests in the fourth quarter of 2019, 2018 and 2017 and determined that the carrying values of the Company’s goodwill were not impaired. The Company completed its required annual impairment tests in the fourth quarter of 2019, 2018 and 2017 and determined that the carrying values of the Company’s other intangible assets with indefinite lives were not impaired. Other intangible assets with finite lives are evaluated for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of other intangible assets with finite lives is considered impaired when the total projected undiscounted cash flows from the asset group are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of those assets. Fair value is determined primarily using present value techniques based on projected cash flows from the asset group. Intangible assets, other than goodwill, with definite lives are amortized over their estimated useful lives. Patents and technology are being amortized over useful lives of five five
Financial Instruments and Foreign Currency Translation	Financial Instruments and Foreign Currency Translation Assets and liabilities of foreign operations are translated using exchange rates in effect at the balance sheet date and their results of operations are translated using average exchange rates for the year. Certain transactions of the Company and its subsidiaries are denominated in currencies other than their functional currency. Exchange gains and losses from those transactions are included in operating results for the year. The Company makes infrequent use of derivative financial instruments. Forward contracts are entered into from time to time to hedge certain inventory purchases, export sales, debt or foreign currency transactions, thereby minimizing the Company’s exposure to raw material commodity price or foreign currency fluctuation. In instances where transactions are designated as hedges of an underlying item, the gains and losses on those transactions are included in accumulated other comprehensive income within stockholders’ equity to the extent they are effective as hedges. An evaluation of hedge effectiveness is performed by the Company on an ongoing basis and any changes in the hedge are made as appropriate.
Revenue Recognition	Revenue Recognition Revenue is derived from sales of products and services. The Company’s products and services are marketed and sold worldwide through two operating groups: EIG and EMG. See Note 15 Descriptive Information about Reportable Segments The majority of the Company’s revenues on product sales were recognized at a point in time when the customer obtains control of the product. The transfer in control of the product to the customer was typically evidenced by one or more of the following: the customer having legal title to the product, the Company’s present right to payment, the customer’s physical possession of the product, the customer accepting the product, or the customer having the benefits of ownership or risk of loss. For a small percentage of sales where title and risk of loss transfers at the point of delivery, the Company recognized revenue upon delivery to the customer, which is the point that control transferred, assuming all other criteria for revenue recognition were met.
Research and Development	Research and Development Research and development costs
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are included in Cost of sales and were $66.7 million in 2019, $62.7 million in 2018 and $53.1 million in 2017.
Share-Based Compensation	Share-Based Compensation The Company expenses the fair value of share-based awards made under its share-based plans in the consolidated financial statements over their requisite service period of the grants.
Income Taxes	Income Taxes The Company’s process of providing for income taxes and determining the related balance sheet accounts requires management to assess uncertainties, make judgments regarding outcomes and utilize estimates. The Company conducts a broad range of operations around the world and is therefore subject to complex tax regulations in numerous international taxing jurisdictions, resulting at times in tax audits, disputes and potential litigation, the outcome of which is uncertain. Management must make judgments currently about such uncertainties and determine estimates of the Company’s tax assets and liabilities. To the extent the final outcome differs, future adjustments to the Company’s tax assets and liabilities may be necessary. The Company recognizes interest and penalties accrued related to uncertain tax positions in income tax expense. The Company assesses the realizability of its deferred tax assets, taking into consideration the Company’s forecast of future taxable income, available net operating loss carryforwards and available tax planning strategies that could be implemented to realize the deferred tax assets. Based on this assessment, management must evaluate the need for, and amount of, valuation allowances against the Company’s deferred tax assets. To the extent facts and circumstances change in the future, adjustments to the valuation allowances may be required.
Pensions	Pensions The Company has U.S. and foreign defined benefit and defined contribution pension plans. The most significant elements in determining the Company’s pension income or expense are the assumed pension liability discount rate and the expected return on plan assets. All unrecognized prior service costs, remaining transition obligations or assets and actuarial gains and losses have been recognized, net of tax effects, as a charge to accumulated other comprehensive income in stockholders’ equity and will be amortized as a component of net periodic pension cost. The Company uses a measurement date of December 31 (its fiscal year end) for its U.S. and foreign defined benefit plans.
Earnings Per Share	Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding stock options and restricted stock grants). The number of weighted average shares used in the calculation of basic earnings per share and diluted earnings per share was as follows for the years ended December 31: 2019 2018 2017 (In thousands) Weighted average shares: Basic shares 227,759 230,823 230,229 Equity-based compensation plans 1,636 1,889 1,616 Diluted shares 229,395 232,712 231,845
