Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Entegris, Inc. (Entegris or the Company) is a leading global developer, manufacturer and supplier of microcontamination control products, specialty chemicals and advanced materials handling solutions for manufacturing processes in the semiconductor and other high-technology industries. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation. Use of Estimates and Basis of Presentation The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make judgments, estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, Entegris evaluates its estimates, including those related to receivables, inventories, property, plant and equipment, goodwill, intangible assets, accrued liabilities, income taxes and share-based compensation, among others. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid debt securities with original maturities of three months or less, which are valued at cost and approximates fair value. Allowance for Doubtful Accounts An allowance for uncollectible trade receivables is estimated based on a combination of write-off history, aging analysis and any specific, known troubled accounts. The Company maintains an allowance for doubtful accounts that management believes is adequate to cover expected losses on trade receivables. Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined by the first-in, first-out (FIFO) method. Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our consolidated balance sheet. We do not have material financing leases. Operating assets and liabilities are recognized at commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU assets includes prepaid lease payments and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease and non-lease components are generally accounted for separately for real estate leases. For non-real estate leases, we account for the lease and non-lease components as a single lease component. Property, Plant, and Equipment Property, plant and equipment are carried at cost and are depreciated on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. Maintenance and repairs are expensed as incurred, while significant additions and improvements are capitalized. Long-lived assets, including property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable based on estimated future undiscounted cash flows. The amount of impairment, if any, is measured as the difference between the net book value and the estimated fair value of the asset(s). Fair Value of Financial Instruments The carrying value of cash equivalents, accounts receivable, accounts payable, accrued payroll and related benefits, and other accrued liabilities approximates fair value due to the short maturity of those instruments. The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $958 million at December 31, 2019 compared to the carrying amount of long-term debt, including current maturities, of $936 million at December 31, 2019. Goodwill and Intangible Assets Goodwill represents the excess of acquisition costs over the fair value of the net assets of businesses acquired. Goodwill is not subject to amortization, but is tested for impairment annually at August 31, the Company’s annual testing date, and whenever events or changes in circumstances indicate that impairment may have occurred. The Company compares the carrying value of its reporting units, including goodwill, to their fair value. For reporting units in which the assessment indicates that it is more likely than not that the fair value is more than its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. Based on its annual analysis, the Company determined there was no indication of impairment of goodwill and the estimated fair value of each reporting unit substantially exceeded its carrying value. Amortizable intangible assets include, among other items, patented, unpatented and other developed technology and customer-based intangibles, and are amortized using the straight-line method over their respective estimated useful lives. The Company reviews intangible assets and other long-lived assets for impairment if changes in circumstances or the occurrence of events suggest the remaining value may not be recoverable. Derivative Financial Instruments The Company records derivatives as assets or liabilities on the balance sheet and measures such instruments at fair value. Changes in fair value of derivatives are recorded each period in the Company’s consolidated statements of operations. The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as other expense (income), net, in the Company’s consolidated statements of operations. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments. Foreign Currency Translation Assets and liabilities of certain foreign subsidiaries are translated from foreign currencies into U.S. dollars at period-end exchange rates, and the resulting gains and losses arising from translation of net assets located outside the U.S. are recorded as a cumulative translation adjustment, a component of accumulated other comprehensive loss in the consolidated balance sheets. Income statement amounts are translated at the weighted average exchange rates for the year. Translation adjustments are not adjusted for income taxes, as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Gains and losses resulting from foreign currency transactions are included in other expense (income), net, in the Company’s consolidated statements of operations. Revenue Recognition Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and Handling Costs Shipping and handling costs incurred are recorded in cost of sales in the Company’s consolidated statements of operations. Engineering, Research and Development Expenses Engineering, research and development costs are expensed as incurred. Share-based Compensation The Company measures the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant. Compensation expense is recognized using the straight-line attribution method to recognize share-based compensation over the service period of the award, with adjustments recorded for forfeitures as they occur. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes these assets are more likely than not to be realized. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that the Company would not be able to realize all or part of its deferred tax assets. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company’s policy for recording interest and penalties associated with audits and unrecognized tax benefits is to record such items as a component of income before taxes. Penalties and interest to be paid or received are recorded in other expense (income), net, in the statement of operations. Comprehensive Income (Loss) Comprehensive income (loss) represents the change in equity resulting from items other than shareholder investments and distributions. The Company’s foreign currency translation adjustments, unrealized gains and losses on available-for-sale investments, and minimum pension liability adjustments are included in accumulated other comprehensive loss. Comprehensive income (loss) and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income (loss) and consolidated statements of equity. Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB established Topic 842, Leases , by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and expense recognition in the income statement. The Company adopted ASU No. 2016-02 using the modified retrospective method. See Note 10 Leases to the consolidated financial statements for further details. Recent Accounting Pronouncements Yet to be Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace the current “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The Company is required to adopt this new guidance in the first quarter of fiscal 2020. The Company is reviewing the provisions of the new standard and currently does not expect a material effect on its consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	REVENUES Revenue Recognition Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sales. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from advance payments received on sales of the Company’s products. The Company makes the required disclosures below. The Company does not disclose information about remaining performance obligations that have original expected durations of one year or less. Nature of goods and services The following is a description of principal activities from which the Company generates its revenues. The Company has three reportable segments. For more detailed information about reportable segments, see note 16 to the consolidated financial statements. For each of the three reportable segments, the recognition of revenue regarding the nature of goods and services provided by the segments are similar and described below. The Company recognizes revenue for product sales at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment or delivery, depending on the terms of the underlying contracts. For product sales contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognizes the related revenue as control of each individual product is transferred to the customer in satisfaction of the corresponding performance obligations. The Company generally recognizes revenue for sales of services when the Company has satisfied the performance obligation. The payment terms and revenue recognized is based on time and materials. The Company also enters into arrangements to license its intellectual property. These arrangements typically permit the customer to use a specialized manufacturing process and in return the Company receives a royalty fee. The Company recognizes revenue for a sales-based or usage-based royalty promised in exchange for a license of intellectual property when the subsequent sale or usage occurs. The Company offers certain customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction in sales at the time revenue is recognized in an amount estimated based on historical experience and contractual obligations. The Company periodically reviews the assumptions underlying its estimates of discounts and volume rebates and adjusts its revenues accordingly. In addition, the Company offers free product rebates to certain customers. The Company utilizes an adjusted market approach to estimate the stand-alone selling price of the loyalty program and allocates a portion of the consideration received to the free product offering. The free product offering is redeemable upon future purchases of the Company’s products. The amount associated with free product rebates is recorded as deferred revenue on the balance sheet and is recognized as revenue when the free product is redeemed or when the likelihood of redemption is remote. The Company has deemed that the amount is immaterial for disclosure. The Company applies the practical expedient in ASU No. 2014-09 and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Company provides for the estimated costs of fulfilling its obligations under product warranties at the time the related revenue is recognized. The Company estimates the costs based on historical failure rates, projected repair costs, and knowledge of specific product failures (if any). The specific warranty terms and conditions vary depending upon the product sold and the country in which we do business, but generally include parts and labor over a period generally ranging from 90 days to one year. The Company regularly reevaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjusts the amounts as necessary. The Company’s contracts are generally short-term in nature. Most contracts do not exceed twelve months. Payment terms vary by the type and location of the Company’s customers and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. Those customers that prepay are represented by the contract liabilities below until the performance obligations are satisfied. The following table provides information about contract liabilities from contracts with customers. The contract liabilities are included in other accrued liabilities balance in the consolidated balance sheet.

The fixed deferred payment is reflected in pension benefit obligations and other liabilities in the Company’s consolidated balance sheets. Upon closing the acquisition, the Company recorded a contingent consideration obligation of $0.7 million , which represents the fair value of the earnout-based contingent consideration. This amount was estimated based on a Black Scholes model. Subsequent changes in the fair value of this obligation will be recognized as adjustments to the contingent consideration obligation and reflected within the Company’s consolidated statements of operations. On December 3, 2019, the Company entered into a settlement agreement to accelerate the fixed deferred payment of $16.1 million to no later than March 8, 2020. The Company adjusted the fair value of the fixed deferred payment from its fair value to the full value resulting in an additional $1.6 million charge to interest expense in the consolidated income statement and the liability was adjusted from other long-term liabilities to other accrued liabilities. In addition the acceleration of the fixed deferred payment, it was determined the earnout-based contingent consideration of $0.7 million will never become owed to the sellers under the original purchase agreement.

The following table summarizes the provisional allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the acquisition and adjusted as of December 31, 2019. (In thousands): As of June 30, 2018 As of December 31, 2019 Trade accounts and notes receivable, net $ 15,805 $ 19,173 Inventories, net 46,073 42,758 Other current assets 424 706 Property, plant and equipment, net 7,345 6,653 Identifiable intangible assets 178,220 150,430 Deferred tax asset — 734 Other noncurrent assets 398 12 Current liabilities (26,196 ) (26,473 ) Deferred tax liabilities (42,110 ) (35,271 ) Other noncurrent liabilities (1,006 ) (1,412 ) Net assets acquired 178,953 157,310 Goodwill 162,251 184,180 Total purchase price, net of cash acquired $ 341,204 $ 341,490 The fair value of acquired inventories of $42.8 million is valued at the estimated selling price less the cost of disposal and reasonable profit for the selling effort. The fair value write-up of acquired work-in-process and finished goods inventory was $8.9 million , the amount of which will be amortized over the expected turn of the acquired inventory. Accordingly, a $2.0 million and a $6.9 million incremental cost of sales charge associated with the fair value write-up of inventory acquired in the acquisition of SPG was recorded for the years ended December 31, 2019 and 2018, respectively. The fair value of acquired property, plant and equipment of $6.7 million is valued at its value-in-use. The Company recognized the following finite-lived intangible assets as part of the acquisition of SPG: (In thousands) Amount Weighted average life in years Developed technology $ 20,070 8.0 Trademarks and trade names 6,670 12.0 Customer relationships 107,790 12.0 Other 15,900 0.9 $ 150,430 10.0 The acquired identifiable intangible assets are being amortized on a straight-line basis. The fair value of acquired identifiable intangible assets was determined using the “income approach”. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations, discount rate and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by the Company’s management. There are inherent uncertainties and management judgment required in these determinations. The fair value measurements of the assets acquired and liabilities assumed were based on valuations involving significant unobservable inputs, or Level 3 in the fair value hierarchy. The purchase price of SPG exceeded the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $184.2 million . Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. The purchase price also included the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value in addition to a going-concern element that represents the Company’s ability to earn a higher rate of return on the group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill. No amount of goodwill is expected to be deductible for income tax purposes. During the quarter ended June 29, 2019, the Company finalized its fair value determination of the assets acquired and liabilities assumed. The valuation of the assets acquired and liabilities assumed was based on the information that was available as of the acquisition date, and the expectations and assumptions that have been deemed reasonable by the Company’s management. Particle Sizing Systems On January 22, 2018 , the Company acquired Particle Sizing Systems, LLC (PSS), which provides particle sizing instrumentation for liquid applications to the semiconductor and life science industries. The acquired assets and assumed liabilities became part of the Company’s Advanced Materials Handling segment. The transaction was accounted for under the acquisition method of accounting and the results of operations of PSS are included in the Company’s consolidated financial statements since January 22, 2018. The acquisition does not constitute a material business combination. The purchase price for PSS was cash consideration of $37.3 million , funded from the Company’s existing cash on hand. Costs associated with the acquisition of the product line were not significant and were expensed as incurred. The purchase price of PSS exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $8.8 million . Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. This additional investment value resulted in goodwill, which is expected to be deductible for income tax purposes. The following table summarizes the final allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of acquisition and adjusted as of December 31, 2018.

In November 2018, the Company entered into the New Term Loan Facility and the New Revolving Facility described below. The Company used the net proceeds of the term loans under the New Term Loan Facility to repay and terminate the Previous Credit Facilities, described below, to pay fees and expenses related to the issuance and the repayment, and for general corporate purposes. In October 2019, the Company amended its credit and guaranty agreement (the “Credit Agreement”) dated as of November 6, 2018. The amendment changed the agency bank from Goldman Sachs Bank USA, as administrative agent and collateral agent, to Morgan Stanley, and adds two additional lenders to the Company’s Credit Agreement. There was no change to the total commitment or the term length for either the New Term Loan Facility or the New Revolving Facility as defined below under Senior Secured Credit Facilities. However, the amendment changed the amount committed for each of the previous lenders. Debt issuance costs of $5.1 million for the year ended December 31, 2018 were paid to third parties are capitalized as debt issuance costs in connection with the New Credit Facilities. These debt issuance costs are being amortized as interest expense in the Company’s consolidated statements of operations over the term of the debt instrument using the straight-line method. The term loans under the Previous Term Loan Facility were repaid without premium or penalty at 100% of the outstanding principal amount, plus accrued and unpaid interest. 2026 Senior Unsecured Notes On November 10, 2017 , the Company issued $550 million aggregate principal amount of 4.625% senior unsecured notes due February 10, 2026 (“the 2026 Notes”). The 2026 Notes were issued under an indenture dated as of November 10, 2017 (the “2026 Notes Indenture”) by and among the Company and Wells Fargo Bank, National Association, as trustee. Interest on the 2026 Notes is payable semi-annually in arrears on February 15 and August 15, which commenced on February 15, 2018. The 2026 Notes are guaranteed, jointly and severally, fully and unconditionally, on a senior unsecured basis, by, subject to certain exclusions, each of the Company’s domestic subsidiaries that guarantee indebtedness under the New Credit Facilities. As provided in the 2026 Notes Indenture, the Company may at its option on one or more occasions redeem all or a part of the 2026 Notes at a redemption price equal to (a) 100% of the principal amount of the 2026 Notes redeemed plus a make-whole premium if redeemed prior to November 10, 2020 , or (b) 100% of the principal amount of the 2026 Notes redeemed plus a percentage of principal amount between 100% and 103.469% of the aggregate principal amount of the 2026 Notes to be redeemed, depending on the period of redemption, if redeemed on or after November 10, 2020 , plus, in each case, accrued and unpaid interest on the amount of 2026 Notes being redeemed. Upon a change in control accompanied by certain rating events, the Company is required to offer to repurchase all of the 2026 Notes at a price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. The 2026 Notes Indenture contains covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of the Company’s restricted subsidiaries to create liens, enter into sale and leaseback transactions, engage in consolidations or mergers, or sell, transfer or otherwise dispose of all or substantially all of their assets. The 2026 Notes Indenture also, subject to certain exceptions, limits the ability of any subsidiary of the Company that is not a guarantor under the 2026 Notes to incur indebtedness. The Company is in compliance with all of the above covenants at December 31, 2019 . The 2026 Notes Indenture also provides for events of default which, if certain of them occur, would permit the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2026 Notes to declare the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding 2026 Notes to be due and payable immediately. Senior Secured Credit Facilities On November 6, 2018 , the Company entered into a credit and guaranty agreement (the “Credit Agreement”) with Goldman Sachs Bank US A, subsequently amended in October of 2019 to Morgan Stanley, as administrative agent and collateral agent, and the lenders party thereto, that provides senior secured financing in an aggregate principal amount of $700 million , consisting initially of (a) term loans in an aggregate principal amount of $400 million (the “New Term Loan Facility”) and (b) revolving commitments in an aggregate amount of $300 million (the “New Revolving Facility”, and together with the New Term Loan Facility, the “New Credit Facilities”). Borrowings under the New Credit Facilities bear interest at a rate per annum equal to, at the Company’s option, a base rate (such as prime rate or LIBOR) plus an applicable margin. The Company’s interest rate on the term loans under the New Term Loan Facility is 3.80% at December 31, 2019 . In addition to paying interest on the outstanding principal under the New Credit Facilities, the Company will pay (i) with respect to the New Term Loan Facility, customary agency fees, and (ii) with respect to the New Revolving Facility, a commitment fee in respect of the unutilized commitments thereunder and customary letter of credit fees and agency fees. The initial commitment fee is 0.20% per annum. The Company may voluntarily prepay outstanding term loans and revolving loans under the New Credit Facilities and may reduce the unutilized portion of the New Revolving Facility at any time without premium or penalty other than customary “breakage” costs with respect to LIBOR loans. It is unclear whether the LIBOR will continue to be calculated or published as a reference rate/benchmark after 2021.The Company’s New Credit Facilities do not have fallback language for when LIBOR is unavailable. The Company is currently assessing its alternatives and cannot yet reasonably estimate the expected impact. The Company believes that it could renegotiate the agreement prior to the discontinuation to determine an alternative rate. The Credit Agreement requires scheduled quarterly installment payments of 0.25% of the aggregate principal amount of the outstanding term loans commencing March 31, 2019 . The Credit Agreement does not require scheduled amortization under the New Revolving Facility. The Credit Agreement also requires the Company to prepay outstanding term loans, subject to certain exceptions, with (a) up to 50% of the Company’s annual Excess Cash Flow (as defined in the Credit Agreement) and (b) 100% of the net cash proceeds of (i) certain asset sales and casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and (ii) any incurrence or issuance of certain debt, other than debt permitted under the New Credit Facilities. The New Term Loan Facility matures November 6, 2025 and the New Revolving Facility matures November 6, 2023 . At December 31, 2019 , the only outstanding amounts under the New Revolving Facility were undrawn outstanding letters of credit of $0.2 million . All obligations under the New Credit Facilities are unconditionally guaranteed by certain of the Company’s wholly-owned domestic subsidiaries and are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Company’s subsidiaries that have guaranteed the New Credit Facilities. The New Credit Facilities contain a number of negative covenants that, subject to certain exceptions, restrict the Company’s ability and each of the Company’s subsidiaries’ ability to incur additional indebtedness; pay dividends on its capital stock or redeem, repurchase or retire its capital stock or its other indebtedness; make investments, loans and acquisitions, create restrictions on the payment of dividends or other amounts to the Company from the Company’s restricted subsidiaries; engage in transactions with its affiliates; sell assets, including capital stock of its subsidiaries; materially alter the business it conducts; consolidate or merge; incur liens; and engage in sale-leaseback transactions. If at any time, commencing with the fiscal quarter ending March 31, 2019, the Company has revolving borrowings, unreimbursed letter of credit drawings and undrawn letters of credit outstanding in an amount in excess of 35.0% of the commitment amount under the New Revolving Facility, the Credit Agreement requires the Company to maintain a secured net leverage ratio of at least 3.25 to 1.0. The Company is in compliance with all of the above covenants at December 31, 2019 . Previous Senior Secured Loan Facilities On April 30, 2014 , the Company entered into (a) a term loan credit and guaranty agreement with Goldman Sachs Bank USA, as administrative agent, collateral agent, sole lead arranger, sole bookrunner and sole syndication agent, that provided senior secured financing of $460.0 million (the “Previous Term Loan Facility”) and (b) an asset-based revolving credit and guaranty agreement with Goldman Sachs Bank USA, as administrative agent, collateral agent, sole lead arranger, sole bookrunner and sole syndication agent, that provided senior secured financing of $75.0 million , subject to a borrowing base (the “Previous ABL Loan Facility”). As stated above, the Previous Term Loan Facility and the Previous ABL Loan Facility were repaid in full in November 2018. The repayment of the Previous Term Loan Facility and the Previous ABL Loan Facility resulted in a loss of $2.3 million for the year ended December 31, 2018 on extinguishment of debt, which is included in other expense (income), net in the Company’s consolidated statement of operations.

Leases [Abstract]
Lease Commitments	LEASES Adoption of ASC ASU No. 2016-02, Leases On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective method applied to existing leases in place as of January 1, 2019. Leases entered into after January 1, 2019 are presented under the provisions of ASU No. 2016-02, while prior periods are not adjusted and continue to be reported in accordance with previous accounting guidance. Leases commencing or renewing after the adoption date are evaluated based on the guidance in ASU No. 2016-02 and may result in more finance leases being recognized even for the renewal of previously classified operating leases. The Company elected to adopt the ‘package of practical expedients’, which permitted the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the practical expedient pertaining to land easements, which allowed the Company to exclude evaluation of all existing land easements in connection with the adoption of the new lease requirements to assess whether they meet the definition of a lease. The Company did not elect the use-of-hindsight practical expedient and therefore did not reassess the lease terms for purposes of calculation of the lease liabilities and right-of-use assets at the adoption date. The Company elected the short-term lease recognition exemption for all leases that qualified. This means, for those leases that qualified, the Company did not recognize right-of-use assets or lease liabilities, and this included not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all leases other than leases of real estate, and this included not separating lease and non-lease components for all leases other than leases of real estate in transition. The Company adopted ASU 2016-02 using the modified retrospective method, recognizing the cumulative effect of application as an adjustment to the opening balance sheet. The standard had a material impact on our consolidated balance sheets, but did not have a material impact on our consolidated statement of income or cash flows. The most significant impact was the recognition of the right-of-use asset and lease liabilities for operating leases. As of December 31, 2019, we do not have any material finance leases. The details of the impact of the changes made to the Company’s consolidated balance sheet date as of January 1, 2019, the date of adoption, are reflected in the following table. ( In thousands ) Debit/(Credit) Right-of-use assets $ 46,162 Prepaid rent (646 ) Short-term lease liability (8,892 ) Short-term deferred rent 274 Long-term lease liability (42,639 ) Long-term deferred rent 5,741 Deferred tax asset 11,629 Deferred tax liability (11,629 ) Leases As of December 31, 2019 , the Company was obligated under operating lease agreements for certain sales offices and manufacturing facilities, manufacturing equipment, vehicles, information technology equipment and warehouse space. Our leases have remaining lease terms of 1 year to 14 years, some of which may include options to extend the lease for up to 6 years, and some of which may include options to terminate the leases within 1 year . For the year ended December 31, 2019 , the Company has obtained $9.1 million of operating lease assets in exchange for lease obligations. As of December 31, 2019 , the Company’s operating lease components with initial or remaining terms in excess of one year were classified on the consolidated balance sheet as follows: ( In thousands ) Classification December 31, 2019 Assets Right-of-use assets Right-of-use assets $ 50,160 Liabilities Short-term lease liability Other accrued liabilities 10,025 Long-term lease liability Long-term lease liability 43,827 Total lease liabilities $ 53,852 Expense for leases less than 12 months for the year ended December 31, 2019 were not material.

In return for this commitment, the Company had a tax holiday on income earned on sales of these products for five years and a partial holiday for two additional years. The income tax benefits attributable to this tax holiday are $4.0 million ( $0.03 per diluted share) and $7.4 million ( $0.05 per diluted share) for the years ended December 31, 2018 and 2017, respectively. The tax holiday benefit ceased during the year ended December 31, 2018. The 2017 effective tax rate included an additional benefit of $4.3 million since the corporate tax rate in Korea was lower than the U.S. rate. The Company also has made employment and spending commitments to Singapore. In return for those commitments, the Company has been granted a partial tax holiday for eight years starting in 2013. During 2017, this agreement was extended to 2027 in exchange for revised employment and spending commitments. The income tax benefits attributable to the tax status are $5.8 million ( $0.04 per diluted share), $6.3 million ( $0.04 per diluted share) and $4.7 million ( $0.03 per diluted share) for the years ending December 31, 2019, 2018 and 2017, respectively. The 2019, 2018 and 2017 effective tax rates include additional benefits of $3.3 million , $3.6 million and $12.4 million , because the corporate tax rate in Singapore is lower than the U.S. rate. At December 31, 2019, there were approximately $35.9 million of accumulated undistributed earnings of subsidiaries outside of the United States, all of which are considered to be indefinitely reinvested. Management estimates that no material withholding taxes would be incurred if these undistributed earnings were distributed. The significant components of the Company’s deferred tax assets and deferred tax liabilities at December 31, 2019 and 2018 are as follows: (In thousands) 2019 2018 Deferred tax assets attributable to: Accounts receivable $ 87 $ 247 Inventory 6,517 4,085 Accruals not currently deductible for tax purposes 7,568 8,694 Net operating loss and credit carryforwards 22,316 15,878 Capital loss carryforward — 2,450 Equity compensation 3,415 3,054 Asset impairments 452 452 Other, net 5,990 3,488 Gross deferred tax assets 46,345 38,348 Valuation allowance (20,118 ) (18,079 ) Total deferred tax assets 26,227 20,269 Deferred tax liabilities attributable to: Purchased intangible assets (44,447 ) (50,128 ) Depreciation (6,491 ) (3,874 ) Total deferred tax liabilities (50,938 ) (54,002 ) Net deferred tax liabilities $ (24,711 ) $ (33,733 ) Deferred tax assets are generally required to be reduced by a valuation allowance if, based on the weight of available positive and negative evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2019 and 2018 , the Company had a net U.S. deferred tax liability of $12.2 million and $24.5 million , respectively, which are composed of temporary differences and various tax credit carryforwards. Management believes that it is more likely than not that the benefit from certain state net operating loss carryforwards and state credits will not be realized. In recognition of this risk, management has provided a valuation allowance of $10.4 million and $10.7 million as of December 31, 2019 and 2018 , respectively, on the related deferred tax assets. If the assumptions change and management determines the assets will be realized, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets at December 31, 2019 will be recognized as a reduction of income tax expense. At December 31, 2019 , the Company had state operating loss and credit carryforwards of approximately $10.5 million , which begin to expire in 2020 and foreign operating loss carryforwards of $29.6 million , which begin to expire in 2020 . As of December 31, 2019 and 2018 , the Company had a net non-U.S. deferred tax asset of $7.7 million and $8.8 million , respectively, for which management determined based upon the available evidence a valuation allowance of $9.7 million and $7.3 million as of December 31, 2019 and 2018, respectively, was required against the non-U.S. gross deferred tax assets. For other non-U.S. jurisdictions, management is relying upon projections of future taxable income to utilize deferred tax assets. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax positions will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that fail to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The provisions also provide guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties. Reconciliations of the beginning and ending balances of the total amounts of gross unrecognized tax benefits for the years ended December 31, 2019 and 2018 are as follows: (In thousands) 2019 2018 Gross unrecognized tax benefits at beginning of year $ 12,295 $ 12,561 Increase in tax positions from prior years 1,786 61 Decrease in tax positions from prior years (54 ) (234 ) Increases in tax positions for current year 3,414 2,970 Settlement of tax positions for current year (421 ) (2,577 ) Lapse in statute of limitations (826 ) (486 ) Gross unrecognized tax benefits at end of year $ 16,194 $ 12,295 The total amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate was $12.5 million at December 31, 2019 . Penalties and interest paid or received are recorded in other income, net, in the consolidated statements of operations. As of December 31, 2019 and 2018 , the Company has accrued interest and penalties related to unrecognized tax benefits of $3.9 million and $1.7 million , respectively. Expenses of $0.6 million , $0.8 million and $0.3 million were recognized as interest and penalties in the consolidated statements of operations for the years ended December 31, 2019 , 2018 and 2017 , respectively. The Company files income tax returns in the U.S. and in various state, local and foreign jurisdictions. The statutes of limitations related to both the consolidated Federal income tax return and state returns are closed for all years up to and including 2015 and 2015 , respectively. With respect to foreign jurisdictions, the statute of limitations varies from country to country, with the earliest open year for the Company’s major foreign subsidiaries being 2013 . Due to the expiration of various statutes of limitations and settlement of audits, it is reasonably possible that the Company’s gross unrecognized tax benefit balance may decrease within the next twelve months by approximately $2.0 million .

The credit agreement governing the New Credit Facilities contain restrictions that may limit our ability to continue to repurchase shares. 2010 Stock Plan In 2009, the Company’s Board of Directors approved the 2010 Stock Plan, subject to the approval by the Company’s stockholders in 2010. The 2010 Stock Plan replaced the predecessor plans for future stock awards and stock option grants. Subsequent to the acquisition of ATMI, Inc. in 2014, the Company’s Board of Directors approved the absorption of 5.7 million additional shares of the ATMI, Inc. 2010 Stock Plan (ATMI Plan) into the Company’s 2010 Stock Plan for the remaining term of the ATMI Plan. The 2010 Stock Plan has a term of ten years and provides for the issuance of stock options and other share-based awards to selected employees, directors, and other individuals or entities that provide services to the Company or its affiliates. Under the 2010 Stock Plan, the Board of Directors or a committee selected by the Board of Directors will determine for each award, the term, price, number of shares, rate at which each award is exercisable and whether restrictions are imposed on the shares subject to the awards. The exercise price for option awards generally may not be less than the fair market value per share of the underlying common stock on the date granted. The 2010 Stock Plan provides that after December 31, 2009 any shares subject to stock awards that were awarded from the Company’s expired plans and that are forfeited, expired or otherwise terminated without issuance of shares will again be available for issuance under the 2010 Stock Plan. Stock Options Stock option activity for the 2010 Stock Plan for the years ended December 31, 2019 , 2018 and 2017 is summarized as follows: 2019 2018 2017 (Shares in thousands) Number of shares Weighted average exercise price Number of shares Weighted average exercise price Number of shares Weighted average exercise price Options outstanding, beginning of year 1,410 $ 18.22 1,869 $ 13.46 1,907 $ 11.54 Granted 293 33.33 296 31.10 335 21.60 Exercised (128 ) 13.89 (727 ) 10.89 (359 ) 10.89 Expired or forfeited — — (28 ) 26.41 (14 ) 12.78 Options outstanding, end of year 1,575 $ 21.39 1,410 $ 18.22 1,869 $ 13.46 Options exercisable, end of year 788 $ 15.75 562 $ 13.68 872 $ 11.11 Options outstanding for the Company’s stock plans at December 31, 2019 are summarized as follows: (Shares in thousands) Options outstanding Options exercisable Range of exercise prices Number outstanding Weighted average remaining life in years Weighted- average exercise price Number exercisable Weighted average exercise $9.88 to $11.71 71 1.1 years $ 11.71 71 $ 11.71 $12.20 to $12.20 416 3.1 years 12.20 292 12.20 $13.49 to $13.49 226 2.1 years 13.49 226 13.49 $21.60 to $21.60 287 4.1 years 21.60 129 21.60 $31.10 to $31.10 282 5.1 years 31.10 70 31.10 $33.33 to $33.33 293 6.1 years 33.33 — — 1,575 4.0 years $ 21.39 788 $ 15.75 The weighted average remaining contractual term for options outstanding and options exercisable for all plans at December 31, 2019 was 4.0 years and 3.0 years, respectively. Under the 2010 Stock Plan, the Company had shares available for future grants of 8.2 million shares, 8.7 million shares, and 8.8 million shares at December 31, 2019 , 2018 and 2017 , respectively. Under the 2010 Stock Plan, the total pre-tax intrinsic value of stock options exercised during the years ended December 31, 2019 and 2018 was $3.2 million and $16.7 million , respectively. The aggregate intrinsic value, which represents the total pre-tax intrinsic value based on the Company’s closing stock price of $50.09 at December 31, 2019 , which theoretically could have been received by the option holders had all option holders exercised their options as of that date, was $45.2 million and $27.1 million for options outstanding and options exercisable, respectively. Share-based payment awards in the form of stock option awards for 0.3 million , 0.3 million and 0.3 million shares were granted to employees during the years ended December 31, 2019 , 2018 and 2017 , respectively. Compensation expense is based on the grant date fair value. The awards vest annually over a four -year period and have a contractual term of 7 years. The Company estimates the fair value of stock options using the Black-Scholes valuation model. Key inputs and assumptions used to estimate the fair value of stock options include the grant price of the award, the expected option term, volatility of the Company’s stock, the risk-free rate and the Company’s dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of reasonableness of the original estimates of fair value made by the Company. The fair value of each stock option grant was estimated at the date of grant using a Black-Scholes option pricing model. The following table presents the weighted-average assumptions used in the valuation and the resulting weighted-average fair value per option granted for the years ended December 31, 2019 , 2018 and 2017 : Employee stock options: 2019 2018 2017 Volatility 31.6 % 28.7 % 26.9 % Risk-free interest rate 2.5 % 2.4 % 1.7 % Dividend yield 0.8 % 1 % — % Expected life (years) 4.1 3.9 4.1 Weighted average fair value per option $ 8.89 $ 7.35 $ 5.25 A historical daily measurement of volatility is determined based on the expected life of the option granted. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by reference to the Company’s historical experience. The Company determines the dividend yield by dividing the expected annual dividend on the Company’s stock by the option exercise price. Employee Stock Purchase Plan The Company maintains the Entegris, Inc. Amended and Restated Employee Stock Purchase Plan (ESPP). The ESPP allows employees to elect, at six-month intervals, to contribute up to 10% of their compensation, subject to certain limitations, to purchase shares of common stock at a discount of 15% from the fair market value on the first day or last day of each six-month period. The Company treats the ESPP as a compensatory plan. At December 31, 2019 , 1.7 million shares remained available for issuance under the ESPP. Employees purchased 0.2 million shares, 0.2 million shares and 0.2 million shares, at a weighted-average price of $28.67 , $24.86 , and $16.92 during the years ended December 31, 2019 , 2018 and 2017 , respectively. Restricted Stock Units Restricted stock units are awards of common stock made under the 2010 Stock Plan that are subject to a risk of forfeiture if the awardee terminates employment with the Company prior to the lapse of the restrictions. The value of such restricted stock units is determined using the market price on the grant date. Compensation expense for restricted stock units is generally recognized using the straight-line single-option method. A summary of the Company’s restricted stock unit activity for the years ended December 31, 2019 , 2018 and 2017 is presented in the following table: 2019 2018 2017 (Shares in thousands) Number of shares Weighted average grant date fair value Number of shares Weighted average grant date fair value Number of shares Weighted average grant date fair value Unvested, beginning of year 1,519 $ 21.24 1,857 $ 15.86 2,164 $ 12.49 Granted 514 34.05 509 31.40 659 22.14 Vested (679 ) 18.89 (732 ) 15.07 (801 ) 12.22 Forfeited (100 ) 24.82 (115 ) 18.58 (165 ) 14.48 Unvested, end of year 1,254 27.48 1,519 21.24 1,857 15.86 The weighted average remaining contractual term for unvested restricted shares at December 31, 2019 and 2018 was 2.0 years and 1.9 years, respectively. During the years ended December 31, 2019 , 2018 and 2017 , the Company awarded performance-based restricted stock units for up to 0.1 million shares of common stock, 0.2 million shares of common stock and 0.1 million shares of common stock, respectively, to be issued upon the achievement of performance conditions under the Company’s 2010 Stock Plan to certain officers and other key employees. Compensation expense is based on the grant date fair value. The awards vest on the third anniversary of the award date. The Company estimates the fair value of the performance shares using a Monte Carlo simulation process. As of December 31, 2019 , the total compensation cost related to unvested stock options, performance-based restricted stock units and restricted stock unit awards not yet recognized was $3.7 million , $2.6 million and $22.1 million , respectively, and is expected to be recognized over the next 2.5 years on a weighted-average basis. Valuation and Expense Information The Company recognizes compensation expense for all share-based payment awards made to employees and directors based on their estimated fair values on the date of grant. Compensation expense is recognized using the straight-line attribution method to recognize share-based compensation over the service period of the award, with adjustments recorded for forfeitures as they occur. The following table summarizes the allocation of share-based compensation expense related to employee stock options, restricted stock awards, performance-based restricted stock awards and grants under the employee stock purchase plan for the years ended December 31, 2019 , 2018 and 2017 : (In thousands) 2019 2018 2017 Cost of sales $ 1,180 $ 1,009 $ 1,031 Engineering, research and development expenses 1,901 1,689 1,457 Selling, general and administrative expenses 16,548 14,414 12,818 Share-based compensation expense 19,629 17,112 15,306 Tax benefit 3,626 3,421 4,978 Share-based compensation expense, net of tax $ 16,003 $ 13,691 $ 10,328

The employer matching contribution expense under the 401(k)Plan was $7.1 million , $6.1 million and $5.1 million in the fiscal years ended December 31, 2019 , 2018 and 2017 , respectively. Defined Benefit Plans The employees of the Company’s subsidiaries in Japan, Taiwan and Germany are covered in defined benefit pension plans. The Company uses a December 31 measurement date for its pension plans.

In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, as well as current economic and capital market conditions. The discount rate primarily used by the Company is based on market yields at the valuation date on government bonds as well as the estimated maturity of benefit payments. Plan Assets At December 31, 2019 , the majority of the Company’s pension plan assets are deposited in Bank of Taiwan in the form of money market funds, where the Bank of Taiwan is the assigned funding vehicle for the statutory retirement benefit.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The Company’s financial segment reporting reflects an organizational alignment intended to leverage the Company’s unique portfolio of capabilities to create value for its customers by developing mission-critical solutions to maximize manufacturing yields and enable higher performance of devices. While these segments have separate products and technical know-how, they share a common business systems and processes, technology centers, and strategic and technology roadmaps. The Company leverages its expertise from these three segments to create new and increasingly integrated solutions for its customers. The Company’s business is reported in the following segments: • Specialty Chemicals and Engineered Materials (SCEM): SCEM provides high-performance and high-purity process chemistries, gases, and materials and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes. • Microcontamination Control (MC): MC offers solutions to filter and purify critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries. • Advanced Materials Handling (AMH): AMH develops solutions to monitor, protect, transport, and deliver critical liquid chemistries and substrates for a broad set of applications in the semiconductor industry and other high-technology industries. In the first quarter of 2019, the Company changed its definition of segment profit to include inter-segment sales. The Company updated its recognition of inter-segment sales to recognize the revenue and profit associated with products and components produced in one segment and supplied to another, before being sold to the ultimate end customer. The Company accounts for inter-segment sales and transfers as if the sales or transfers were to third parties, that is, at approximate market prices. Inter-segment sales are presented as an elimination below. Segment profit is defined as net sales less direct and indirect segment operating expenses, including certain general and administrative costs for the Company’s human resources, finance and information technology functions. The remaining unallocated expenses consist mainly of the Company’s corporate functions as well as interest expense, amortization of intangible assets and income tax expense. Prior quarter information has been recast to reflect the change in the Company’s definition of segment profit.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates and Basis of Presentation The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make judgments, estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, Entegris evaluates its estimates, including those related to receivables, inventories, property, plant and equipment, goodwill, intangible assets, accrued liabilities, income taxes and share-based compensation, among others. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid debt securities with original maturities of three months or less, which are valued at cost and approximates fair value.
Allowance For Doubtful Accounts	Allowance for Doubtful Accounts An allowance for uncollectible trade receivables is estimated based on a combination of write-off history, aging analysis and any specific, known troubled accounts. The Company maintains an allowance for doubtful accounts that management believes is adequate to cover expected losses on trade receivables.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value. Cost is determined by the first-in, first-out (FIFO) method.
Leases	Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our consolidated balance sheet. We do not have material financing leases. Operating assets and liabilities are recognized at commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU assets includes prepaid lease payments and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease and non-lease components are generally accounted for separately for real estate leases. For non-real estate leases, we account for the lease and non-lease components as a single lease component.
Property, Plant, And Equipment	Property, Plant, and Equipment Property, plant and equipment are carried at cost and are depreciated on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. Maintenance and repairs are expensed as incurred, while significant additions and improvements are capitalized. Long-lived assets, including property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable based on estimated future undiscounted cash flows. The amount of impairment, if any, is measured as the difference between the net book value and the estimated fair value of the asset(s).
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying value of cash equivalents, accounts receivable, accounts payable, accrued payroll and related benefits, and other accrued liabilities approximates fair value due to the short maturity of those instruments. The fair value of long-term debt, including current maturities, based upon models utilizing market observable (Level 2) inputs and credit risk, was $958 million at December 31, 2019 compared to the carrying amount of long-term debt, including current maturities, of $936 million at December 31, 2019.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of acquisition costs over the fair value of the net assets of businesses acquired. Goodwill is not subject to amortization, but is tested for impairment annually at August 31, the Company’s annual testing date, and whenever events or changes in circumstances indicate that impairment may have occurred. The Company compares the carrying value of its reporting units, including goodwill, to their fair value. For reporting units in which the assessment indicates that it is more likely than not that the fair value is more than its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. Based on its annual analysis, the Company determined there was no indication of impairment of goodwill and the estimated fair value of each reporting unit substantially exceeded its carrying value. Amortizable intangible assets include, among other items, patented, unpatented and other developed technology and customer-based intangibles, and are amortized using the straight-line method over their respective estimated useful lives. The Company reviews intangible assets and other long-lived assets for impairment if changes in circumstances or the occurrence of events suggest the remaining value may not be recoverable.
Derivative Financial Instruments	Derivative Financial Instruments The Company records derivatives as assets or liabilities on the balance sheet and measures such instruments at fair value. Changes in fair value of derivatives are recorded each period in the Company’s consolidated statements of operations. The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as other expense (income), net, in the Company’s consolidated statements of operations. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of certain foreign subsidiaries are translated from foreign currencies into U.S. dollars at period-end exchange rates, and the resulting gains and losses arising from translation of net assets located outside the U.S. are recorded as a cumulative translation adjustment, a component of accumulated other comprehensive loss in the consolidated balance sheets. Income statement amounts are translated at the weighted average exchange rates for the year. Translation adjustments are not adjusted for income taxes, as substantially all translation adjustments relate to permanent investments in non-U.S. subsidiaries. Gains and losses resulting from foreign currency transactions are included in other expense (income), net, in the Company’s consolidated statements of operations.
Revenue Recognition	Revenue Recognition Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs incurred are recorded in cost of sales in the Company’s consolidated statements of operations.
Engineering,Research and Development Expenses	Engineering, Research and Development Expenses Engineering, research and development costs are expensed as incurred.
Share-Based Compensation	Share-based Compensation The Company measures the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant. Compensation expense is recognized using the straight-line attribution method to recognize share-based compensation over the service period of the award, with adjustments recorded for forfeitures as they occur.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes these assets are more likely than not to be realized. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that the Company would not be able to realize all or part of its deferred tax assets. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company’s policy for recording interest and penalties associated with audits and unrecognized tax benefits is to record such items as a component of income before taxes. Penalties and interest to be paid or received are recorded in other expense (income), net, in the statement of operations.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) represents the change in equity resulting from items other than shareholder investments and distributions. The Company’s foreign currency translation adjustments, unrealized gains and losses on available-for-sale investments, and minimum pension liability adjustments are included in accumulated other comprehensive loss. Comprehensive income (loss) and the components of accumulated other comprehensive loss are presented in the accompanying consolidated statements of comprehensive income (loss) and consolidated statements of equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB established Topic 842, Leases , by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and expense recognition in the income statement. The Company adopted ASU No. 2016-02 using the modified retrospective method. See Note 10 Leases to the consolidated financial statements for further details. Recent Accounting Pronouncements Yet to be Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace the current “incurred loss” model and generally will result in the earlier recognition of allowances for losses. The Company is required to adopt this new guidance in the first quarter of fiscal 2020. The Company is reviewing the provisions of the new standard and currently does not expect a material effect on its consolidated financial statements.
