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 June 30, 2019 and December 31, 2018: June 30, 2019 December 31, 2018 Fair Value Fair Value (In thousands) Fixed-income investments $ 8,137 $ 7,655 The fair value of fixed-income investments, which are valued as level 1 investments, was based on quoted market prices. The fixed-income investments are shown as a component of long-term assets on the consolidated balance sheet. For the six months ended June 30, 2019 and 2018, gains and losses on the investments noted above were not significant. No Financial Instruments Cash, cash equivalents and fixed-income investments are recorded at fair value at June 30, 2019 and December 31, 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 June 30, 2019 and December 31, 2018: June 30, 2019 December 31, 2018 Recorded Amount Fair Value Recorded Amount Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,473,695 ) $ (2,611,123 ) $ (2,378,809 ) $ (2,368,676 ) The fair value of short-term Foreign Currency At June 30, 2019, the Company had no

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 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 one month to 14 years. Certain lease agreements contain provisions for future rent increases.

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.

As of June 30, 2019, there was approximately $25.7 million of expected future pre-tax 2.1 two years 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.

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 June 30, 2019 and December 31, 2018 were $28.1 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 damages and personal injury, and seeking compensatory and punitive damages. The Company believes that it has good and valid defenses to each of these claims and intends to defend them vigorously. The Company believes it has established reserves for these lawsuits that are sufficient to satisfy its expected exposure. The Company does not expect the outcome of these matters, either individually or in the aggregate, to materially affect the consolidated results of operations, financial position or cash flows of the Company.
