Fair Value Disclosures [Abstract]
Fair Value Measurements	5. 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. 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 March 31, 2020 and December 31, 2019: March 31, December 31, Fair Value Fair Value (In thousands) Mutual fund investments $ 7,212 $ 8,390 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 investments and other assets on the consolidated balance sheet. For the three months ended March 31, 2020 and 2019, gains and losses on the investments noted above were not significant. No transfers between level 1 and level 2 investments occurred during the three months ended March 31, 2020 and 2019. Financial Instruments Cash, cash equivalents and mutual fund investments are recorded at fair value at March 31, 2020 and December 31, 2019 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 March 31, 2020 and December 31, 2019: March 31, 2020 December 31, 2019 Recorded Fair Recorded Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,845,880 ) $ (2,831,990 ) $ (2,382,041 ) $ (2,531,549 ) The fair value of net short-term Foreign Currency At March 31, 2020, the Company had a Canadian dollar forward contract for a total notional value of 24.0 million Canadian dollars ($0.5 million fair value unrealized loss

Hedging Activities	6. 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 March 31, 2020, these net investment hedges included British-pound-and 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.

Leases

Leases [Abstract]
Leases	8. 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 right of use assets, accrued liabilities and other, and other long-term liabilities on our consolidated balance sheets. Operating lease right of use 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.

Acquisition and Divestiture	9. Acquisition and Divestiture Acquisition The Company spent $116.6 million in cash, net of cash acquired, to acquire IntelliPower in January 2020. IntelliPower designs and manufactures a broad portfolio of ruggedized solutions including uninterruptable power systems, external battery packs, power distribution units and power conditioners. IntelliPower was privately held and is headquartered in Orange, California. IntelliPower is part of EIG. The following table represents the preliminary allocation of the purchase price for the net assets of the IntelliPower acquisition based on the estimated fair values at acquisition (in millions): Property, plant and equipment $ 2.3 Goodwill 55.0 Other intangible assets 58.7 Deferred income taxes (14.2 ) Net working capital and other (1) 14.8 Total cash paid $ 116.6 (1) Includes $6.5 million in accounts receivable, whose fair value, contractual cash flows and expected cash flows are approximately equal. The amount allocated to goodwill is reflective of the benefits the Company expects to realize as IntelliPower’s products and solutions broaden the Company’s differentiated product offerings in the power systems and instruments sectors. At March 31, 2020, the purchase price allocated to other intangible assets of $58.7 million consists of $8.1 million of indefinite-lived intangible trade names, which are not subject to amortization. The remaining $50.6 million of other intangible assets consists of $41.4 million of customer relationships, which are being amortized over a period of 18 years, and $9.2 million of purchased technology, which is being amortized over a period of 18 years. Amortization expense for each of the next five years for the 2020 acquisition is expected to approximate $3 million per year. The Company is in the process of finalizing the measurement of certain tangible and intangible assets and liabilities for its 2020 acquisition of IntelliPower and its fourth quarter 2019 acquisition of Gatan including inventory, property, plant and equipment, goodwill, trade names, customer relationships and purchased technology, and the accounting for income taxes. The IntelliPower acquisition had an immaterial impact on reported net sales, net income and diluted earnings per share for the three months ended March 31, 2020. Had the acquisition been made at the beginning of 2020 or 2019, unaudited pro forma net sales, net income and diluted earnings per share for the three months ended March 31, 2020 and 2019, respectively , Divestiture The Company completed its sale of Reading Alloys to Kymera International in March 2020 for net cash proceeds of $245.3 million in cash. The sale resulted in a pretax gain of $141.0 million, recorded in Other income(expense), net in the Consolidated Statement of Income, and income tax expense of approximately $31.4 million in connection with the sale. Reading Alloys revenue and costs were reported within the EMG segment through the date of sale.

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. The following is a summary of the Company’s stock option activity and related information: Shares Weighted Price Weighted Life Aggregate Value (In thousands) (Years) (In millions) Outstanding at December 31, 2019 4,303 $ 62.50 Granted 963 63.37 Exercised (129 ) 49.26 Forfeited (56 ) 72.12 Outstanding at March 31, 2020 5,081 $ 62.89 6.0 $ 57.6 Exercisable at March 31, 2020 2,112 $ 54.58 3.3 $ 37.3 The aggregate intrinsic value of stock options exercised during the three months ended March 31, 2020 was $6.3 million. The total fair value of stock options vested during the three months ended March 31, 2020 was $0.1 million. As of March 31, 2020, there was approximately $24.7 million of expected future pre-tax The fair value of restricted shares under the Company’s restricted stock arrangement is determined by the product of the number of shares granted and the Company’s closing common stock price on the grant date. 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 date. The following is a summary of the Company’s nonvested restricted stock activity and related information: Shares Weighted Average Fair Value (In thousands) Nonvested restricted stock outstanding at December 31, 2019 561 $ 72.46 Granted 240 63.60 Vested (3 ) 64.05 Forfeited (15 ) 71.34 Nonvested restricted stock outstanding at March 31, 2020 783 $ 69.80 The total fair value of restricted stock vested during the three months ended March 31, 2020 was $0.2 million. As of March 31, 2020, there was approximately $34.7 million of expected future pre-tax In March 2020, the Company granted PRSUs to officers and certain key management-level employees an aggregate target award of approximately 119,000 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, 2020 through December 31, 2022. 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, which represents a performance condition. The grant date fair value of these PRSUs are recognized as compensation expense over the vesting period based on the probable number of awards 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. Total PRSUs outstanding at March 31, 2020 were approximately 266,000.

Contingencies	14. Contingencies 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” agreed-to non-de non-owned Total environmental reserves at March 31, 2020 and December 31, 2019 were $29.4 million and $28.9 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 damages and funds for medical monitoring to detect causally related personal injury, and seeking compensatory and punitive damages. While the Company believes that it has good and valid defenses to each of these claims and intends to defend them vigorously if pursued through trial, the parties agreed to terms to globally settle the cases. After extensive negotiations, the Company entered into a global settlement of these lawsuits for an aggregate amount of $6.8 million, for which the Company had previously established reserves sufficient to cover this settlement. The global settlement is subject to court approval in two class action cases. The class representative plaintiffs have filed motions to preliminarily approve the settlements, which the court recently granted. The court also scheduled a final fairness hearing for August 24, 2020.
