Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of Business	Description of Business CIRCOR International, Inc. (“CIRCOR” or the “Company” or “we”) designs, manufactures and distributes a broad array of flow and motion control products and certain services to a variety of end-markets for use in a wide range of applications to optimize the efficiency and/or ensure the safety of flow control systems. CIRCOR has a global presence and operates major manufacturing facilities in North America, Western Europe, Morocco, India and China. As of December 31, 2020, the Company organized its business segment reporting structure into two segments: CIRCOR Aerospace & Defense ("Aerospace & Defense") and CIRCOR Industrial ("Industrial"). Refer to Note 18, Business Segment and Geographical Information, for further information about the segments. During 2019 and 2020, the Company entered into several significant transactions as described below. In January 2019, the Company sold its Reliability Services ("RS") business for approximately $85 million in cash, on a cash-free, debt-free basis, subject to working capital and other adjustments of approximately $(5) million. The RS business provided lubrication management, chemical flushing services, and oil misting equipment to the oil and gas industry. The RS business was acquired as part of the acquisition of the Colfax Fluid Handling (“FH”) business. The disposal group did not meet the criteria to be classified as discontinued operations. However, it did meet the criteria for presentation as held for sale. Accordingly, the RS assets and liabilities were collapsed as held for sale within the consolidated balance sheet at December 31, 2018. In July 2019, the Company sold its Engineered Valves ("EV") business for a nominal amount, with an earnout of 50% of net income over seven years up to a maximum of $21.8 million (€18 million). The EV business is a long-cycle upstream oil and gas engineered value business. The disposal group met the criteria to be classified as discontinued operations, and is recorded as such within the consolidated financial statements. All prior period comparative financial information has been reclassified to conform with this presentation. In August 2019, the Company sold certain assets and liabilities related to its Spence and Nicholson product lines for $84.5 million, subject to adjustment for working capital and other specified items of approximately $(0.5) million. The Spence and Nicholson product lines include steam regulators, control valves, safety relief valves, temperature regulators, steam traps and other steam accessories and solutions. The disposal group did not meet the criteria to be classified as discontinued operations. In January 2020, the Company completed the sale of the non-core Instrumentation and Sampling (“I&S”) business to Crane Co. for $169.1 million in cash, net of working capital adjustments. The I&S business manufactured fittings, regulators, sampling systems and valves. The disposal group did not meet the criteria to be classified as a discontinued operation. However, it did meet the criteria for presentation as held for sale as of the end of 2019. Accordingly, the I&S assets and liabilities were collapsed as held for sale within the consolidated balance sheet at December 31, 2019. In June 2020, the Company completed the disposition of its Distributed Valves ("DV") business at a cost of $10.8 million inclusive of working capital adjustments, while also retaining certain liabilities related to the business. The DV business was a long-cycle upstream oil and gas engineered valve business. This disposal group met the criteria to be classified as held for sale and a discontinued operation, and was recorded as such within the consolidated financial statements as of December 31, 2019. All prior period comparative financial information has been reclassified to conform with this presentation. For more information on the discontinued operations and held for sale transactions, see Note 3, Discontinued Operations and Assets Held for Sale. Throughout this Annual Report on Form 10-K, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. COVID-19 In March 2020, the World Health Organization declared the outbreak of COVID-19, which continues to spread throughout the U.S. and the world, as a pandemic. The COVID-19 pandemic is continuing to impact on the global economy, resulting in rapidly changing market and economic conditions. As of March 29, 2020, the Company experienced a significant decline in its

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of CIRCOR and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or divested are included in the consolidated financial statements from the date of acquisition or up to the date of disposal. Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation, including the results of discontinued operations and reportable segment information. These reclassifications have no effect on the previously reported net (loss) income. Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. Some of the more significant estimates, some of which are impacted by management’s estimates and assumptions regarding the effects of the COVID-19 pandemic, relate to recoverability of goodwill and indefinite-lived trade names, estimated total costs for ongoing long-term revenue contracts where transfer of control occurs over time, inventory valuation, share-based compensation, amortization and impairment of long-lived assets, income taxes (including valuation allowance), fair value of disposal group, pension benefits obligations, acquisition accounting, penalty accruals for late shipments, asset valuations, and product warranties. While management believes that the estimates and assumptions used in the preparation of the financial statements are appropriate, actual results could differ materially from those estimates considering the increased uncertainties surrounding the severity and duration of COVID-19. Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject to terms customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, as separate line items on the consolidated statements of financial position. Refer to Note 3, Discontinued Operations and Assets Held for Sale, for further information. Revenue Recognition The Company recognizes revenue to depict the transfer of control to the Company’s customers in an amount reflecting the consideration the Company expects to be entitled to in exchange for performance obligations. In order to apply this revenue recognition principle, the Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when, or as, a performance obligation is satisfied. See Note 4, Revenue Recognition for further information. Revenues on point in time contracts are recognized when customer obtains control of the product, which is generally at the time of shipping. Revenues and costs on certain long-term contracts are recognized on the percentage-of-completion method measured on the basis of costs incurred to estimated total costs for each contract. This method is used because management considers it to be the best available measure of progress towards completion on these contracts. Revenues and costs on contracts are subject to changes in estimates throughout the duration of the contracts, and any required adjustments are made in the period in which a change in estimate becomes known. Unbilled receivables for net revenues recognized in excess of the amounts billed for active projects are recognized as contract assets on the balance sheet. The Company provides for the estimated costs to fulfill customer warranty obligations upon the recognition of the related revenue. Shipping and handling costs invoiced to customers are recorded as components of revenues and the associated costs are recorded as cost of revenues. The Company recognizes revenue net of sales returns, rebates, penalties, and discounts. Accounts receivable allowances include sales returns and bad debt allowances. The Company monitors and tracks the amount of product returns and reduces revenue at the time of shipment for the estimated amount of such future returns, based on historical experience. Allowance for Credit Losses The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses or doubtful accounts based upon expected losses, its historical experience, expectation of changes in risk of loss and any specific customer collection issues that it has identified. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered. The following table presents changes in the allowance for doubtful accounts for the years ended December 31 (in thousands): Additions (Reductions) Description Balance at Charged to Charged to Deductions Balance at Year ended December 31, 2020 Deducted from asset account: Allowance for doubtful accounts $ 3,086 $ 6,099 $ 929 $ (1,079) $ 9,035 Year ended December 31, 2019 Deducted from asset account: Allowance for doubtful accounts $ 2,270 $ 1,777 $ (198) $ (763) $ 3,086 Year ended December 31, 2018 Deducted from asset account: Allowance for doubtful accounts $ 2,865 $ (262) $ (95) $ (238) $ 2,270 (1) Uncollectible accounts written off, net of recoveries. Goodwill Goodwill is measured as the excess of the cost of acquisition over the sum of the amounts assigned to identifiable tangible and intangible assets acquired less liabilities assumed. The Company performs an impairment assessment for goodwill at the reporting unit level on an annual basis as of the end of its October month end or more frequently if circumstances warrant. Its annual impairment assessment requires a comparison of the fair value of each of its reporting units to the respective carrying value. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying value of a reporting unit is greater than its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Additionally, the Company will consider the income tax effect from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. Determining the fair value of a reporting unit is subjective and requires the use of significant estimates and assumptions. With the assistance of an independent third-party appraisal firm, the Company estimates the fair value of its reporting units using an income approach based on the present value of future cash flows. It believes this approach yields the most appropriate evidence of fair value. The Company also utilizes the comparable company multiples method and market transaction fair value method to validate the fair value estimate using the income approach. The key assumptions utilized in its discounted cash flow model includes estimates of the rate of revenue growth and the discount rate based on a weighted average cost of capital. Any unfavorable material changes to these key assumptions could potentially impact its fair value determinations. For additional information, see Note 9, Goodwill and Other Intangible Assets. Cost of Revenues Cost of revenues primarily reflects the costs of manufacturing and preparing products for sale and, to a much lesser extent, the costs of performing services. Cost of revenues is primarily comprised of the cost of materials, outside processing, inbound freight, production, direct labor and overhead including indirect labor, which are expenses that directly result from the level of production activity at a manufacturing site. Additional expenses that directly result from the level of production activity at a manufacturing site include purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, utility expenses, property taxes, amortization of inventory step-up from revaluation at the date of acquisition, depreciation of production building and equipment assets, warranty costs, salaries and benefits paid to plant manufacturing management and maintenance supplies. Inventories Inventories are stated at the lower of cost or net realizable value. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual cost. Cost is generally determined on the first-in, first-out (“FIFO”) basis. The Company typically analyzes its inventory aging and projected future usage on a quarterly basis to assess the adequacy of its inventory valuation reserve, which primarily consists of obsolescence and net realizable value estimates. These estimates are measured either on an item-by-item basis or higher-level inventory grouping and determined based on the difference between the cost of the inventory and estimated net realizable value. The provision for inventory valuation reserves is a component of the Company's cost of revenues. Assumptions about future demand are among the primary factors utilized to estimate net realizable value. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Only subsequent inventory transactions via sale or disposal would then release the established inventory reserve. If there were to be a sudden and significant decrease in demand for its products, significant price reductions, or a higher incidence of inventory obsolescence for any reason, including a change in technology or customer requirements, the Company could be required to increase its inventory valuation reserves, which could adversely affect its gross profits. Legal Contingencies The Company is currently involved in various legal claims and legal proceedings, some of which may involve substantial dollar amounts. Periodically, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, it accrues a liability for the estimated loss. The determination of probability and the determination as to whether exposure can be reasonably estimated requires management estimates. Because of uncertainties related to these matters, accruals are based on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to its pending claims and litigation and may revise its estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on its business, results of operations and financial position. For more information see Note 16, Contingencies, Commitments and Guarantees. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets, such as trade names, are generally recorded and valued in connection with a business acquisition. For these assets, the Company performs a qualitative assessment on an annual basis to determine if it is more likely than not the asset is impaired ("Step 0" test). These assets are reviewed at least annually for impairment as of the October month end, or more frequently if facts and circumstances warrant. For any that fail the Step 0 test, the Company performs an impairment assessment at the asset level utilizing a fair value calculation. The Company has the option to bypass the qualitative assessment for an indefinite lived intangible asset in any period and proceed directly to the quantitative impairment test. Determining the fair value is subjective and requires the use of significant estimates and assumptions. With the assistance of an independent third-party appraisal firm, the Company estimates the fair value using the relief from royalty method. For more information see Note 9, Goodwill and Other Intangible Assets. Other Long-Lived Assets In accordance with ASC Topic 360, Plant, Property, and Equipment, the Company performs impairment analyses of long-lived asset groups whenever events and circumstances indicate impairment. If indicators are present, it performs a recoverability test by comparing the sum of the undiscounted future cash flows specific to the asset group to its carrying value. If the recoverability test fails (sum of undiscounted cash flows are less than the asset group's carrying value), it then determines the fair value of the asset group and recognizes an impairment loss if the carrying value exceeds the estimated fair value. For more information, see Note 8, Property, Plant and Equipment. Post-Retirement Benefits Pensions and other post-retirement benefit obligations and net periodic benefit costs are actuarially determined and are affected by several assumptions including the discount rate, mortality, and the expected long-term return on plan assets. Changes in assumptions and differences from actual results will affect the amounts of net periodic benefit cost recognized in future periods. These assumptions may also effect the amount and timing of future cash contributions. As required in the recognition and disclosure provisions of ASC Topic 715, Compensation - Retirement Benefits, the Company recognizes the over-funded or under-funded status of defined benefit post-retirement plans in its balance sheet, measured as the difference between the fair value of plan assets and the benefit obligations (the projected benefit obligation for pension plans and the accumulated post-retirement benefit obligation for other post-retirement plans). The change in the funded status is the net of the recognized net periodic benefit cost, cash contributions to the trust/benefits paid directly by the Company and recognized changes in other comprehensive income. Other comprehensive income changes are due to new actuarial gains and losses, new plan amendments and the amortizations of amounts in the net periodic benefit cost. Unrecognized actuarial gains and losses in excess of the 10% corridor (defined as the threshold above which gains or losses need to be amortized) are being recognized for all plans over the weighted average expected remaining service period of the employee group unless substantially all participants are inactive in which case the average remaining lifetime of covered participants is used. Unrecognized actuarial gains and losses arise from several factors including changes in the benefit obligations from actuarial experience and assumption changes, as well as the difference between expected returns and actual returns on plan assets. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if the Company anticipates that it is more likely than not that it may not realize some or all of a deferred tax asset. In accordance with the provisions of ASC Topic 740, Income Taxes, the Company initially recognizes the financial statement effect of a tax position when, based solely on its technical merits, it is more likely than not (a likelihood of greater than fifty percent) that the position will be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard, are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statute of limitations. De-recognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained. If future results of operations exceed the Company's current expectations, its existing tax valuation allowances may be adjusted, resulting in future tax benefits. Alternatively, if future results of operations are less than expected, future assessments may result in a determination that some or all of the deferred tax assets are not realizable. Consequently, the Company may need to establish additional tax valuation allowances for a portion or all of the gross deferred tax assets, which may have a material adverse effect on its results of operations. Under ASC Topic 740, only the portion of the liability that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., due to the expiration of the statute of limitations) or are not expected to be paid within one year are classified as non-current. It is the Company’s policy to record estimated interest and penalties as income tax expense, and tax credits as a reduction in income tax expense. With respect to global intangible low-taxed income ("GILTI"), the Company has adopted a policy to account for this provision as a period cost. Also, the Company has adopted the impact of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2018-05 in its financial statements. For additional information, see Note 10, Income Taxes. Share-Based Compensation Share-based compensation costs are based on the grant date fair value estimated in accordance with the provisions of ASC Topic 718, Accounting for Share Based Payments, and these costs are recognized over the requisite vesting period. The Black-Scholes option pricing model is used to estimate the fair value of each stock option at the date of grant. Black-Scholes utilizes assumptions related to volatility, the risk-free interest rate, the dividend yield and employee exercise behavior. Expected volatilities utilized in the model are based on the historic volatility of the Company’s stock price. The risk-free interest rate is derived from the U.S. Treasury Yield curve in effect at the time of the grant. The model incorporates exercise and post-vesting service termination assumptions based on an analysis of historical data. For additional information, see Note 13, Share-Based Compensation. Environmental Compliance and Remediation Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to existing conditions caused by past operations, which do not contribute to current or future revenue generation, are expensed. Expenditures that meet the criteria of "Regulated Operations" are capitalized. Liabilities are recorded when environmental assessments and/or remedial efforts are probable and the costs can be reasonably estimated. In accordance with ASC Topic 450, Contingencies, estimated costs are based upon current laws and regulations, existing technology and the most probable method of remediation. Foreign Currency and Foreign Currency Contracts The Company's international subsidiaries operate and report their financial results using local functional currencies. Accordingly, all assets, liabilities, revenues, and costs of these subsidiaries are translated into United States ("U.S.") dollars using exchange rates in effect at the end of the relevant periods. The resulting translation adjustments are presented as a separate component of other comprehensive income. The Company does not provide for U.S. income taxes on foreign currency translation adjustments since it does not provide for such taxes on undistributed earnings of foreign subsidiaries. The Company is exposed to certain risks relating to its ongoing business operations including foreign currency exchange rate risk and interest rate risk. The Company currently uses derivative instruments to manage foreign currency risk on certain business transactions denominated in foreign currencies. To the extent the underlying transactions hedged are completed, these forward contracts do not subject us to significant risk from exchange rate movements because they offset gains and losses on the related foreign currency denominated transactions. These forward contracts do not qualify as hedging instruments and, therefore, do not qualify for fair value or cash flow hedge treatment. Any gains and losses on the Company's contracts are recognized as a component of other expense in its consolidated statements of (loss) income. The Company is subject to exchange rate related gains or losses resulting from foreign currency denominated transactions. Its net foreign exchange losses / (gains) recorded for the years ended December 31, 2020, 2019 and 2018 were $2.9 million, $(0.4) million, and $(1.7) million, respectively and are included in other (income) expense in the consolidated statements of (loss) income. For additional information, see Note 12, Financing Arrangements. Earnings Per Common Share Basic earnings per common share is calculated by dividing net income by the number of weighted average common shares outstanding. Diluted earnings per common share is calculated by dividing net income by the weighted average common shares outstanding and assumes the conversion of all dilutive securities when the effects of such conversion would not be anti-dilutive. Earnings per common share and the weighted average number of shares used to compute net earnings per common share, basic and assuming full dilution, are reconciled below (in thousands, except per share data): Year Ended December 31, 2020 2019 2018 Net Shares Per Share Net Shares Per Share Net Shares Per Share Basic EPS $ (185,498) 19,982 $ (9.28) $ (133,935) 19,903 $ (6.73) $ (39,384) 19,834 $ (1.99) Dilutive securities, principally common stock awards — — — — — — — — — Diluted EPS $ (185,498) 19,982 $ (9.28) $ (133,935) 19,903 $ (6.73) $ (39,384) 19,834 $ (1.99) Certain stock options to purchase common shares and restricted stock units ("RSUs") were anti-dilutive. There were 663,986 anti-dilutive stock options, RSUs, and RSU MSPs for the year ended December 31, 2020 with exercise prices ranging from $33.63 to $71.56. There were 431,165 anti-dilutive stock options and RSUs for the year ended December 31, 2019 with exercise prices ranging from $33.63 to $71.56. There were 1,041,454 anti-dilutive stock options and RSUs for the year ended December 31, 2018 with exercise prices ranging from $26.06 to $71.56. Cash and Cash Equivalents The Company's cash equivalents are invested in time deposits of financial institutions, and it has established guidelines relative to credit ratings, diversification and maturities that are intended to maintain safety and liquidity. Cash equivalents include highly liquid investments with maturity periods of three months or less when purchased. Restricted Cash Restricted cash represents cash that is legally restricted as to withdrawal or usage and includes amounts required to be maintained in relation to employment laws in certain jurisdictions. Other Assets Other assets in the accompanying consolidated balance sheets include deferred debt issuance costs associated with the Company's revolving credit facility, tax receivable, non-current contract assets and other certain assets. Fair Value ASC Topic 820, Fair Value Measurement, defines fair value and includes a framework for measuring fair value and disclosing fair value measurements in financial statements. Fair value is a market-based measurement rather than an entity-specific measurement. The fair value hierarchy makes a distinction between assumptions developed based on market data obtained from independent sources (observable inputs) and the reporting entity’s own assumptions (unobservable inputs). This hierarchy prioritizes the inputs into three broad levels as follows: Level One : Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level Two : Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level Three : Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Fair value information for those assets and liabilities, including their classification in the fair value hierarchy, is included in: Note 12, Financing Arrangements along with Derivative Financial Instruments, and Note 15, Retirement Plans (for assets held in trust). Certain pension plan asset investments are measured at fair value using the net asset value per share (or its equivalent) practical expedient (the “NAV”). The carrying amounts of cash and cash equivalents, restricted cash, trade receivables and trade payables approximate fair value because of the short maturity of these financial instruments. Cash equivalents are carried at cost which approximates fair value at the balance sheet date and is a Level 1 financial instrument. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is generally provided on a straight-line basis over the estimated useful lives of the assets, which typically range from 3 to 40 years for buildings and improvements, 1 to 10 years for manufacturing machinery and equipment, and 3 to 7 years for computer equipment and software. Motor vehicles and furniture and fixtures are typically depreciated over 5 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred. The Company reports depreciation of property, plant and equipment in cost of revenue and selling, general and administrative expenses based on the nature of the underlying assets. Depreciation primarily related to equipment used in the production of inventory is recorded in cost of revenues. Depreciation related to selling and administrative functions is reported in selling, general and administrative expenses. See Note 8, Property, Plant and Equipment for additional information. Research and Development Research and development expenditures, including certain engineering costs, are expensed when incurred and are included in selling, general and administrative expenses. Research and development expenditures for the years ended December 31, 2020, 2019 and 2018 were $8.4 million, $7.6 million and $8.5 million, respectively. Sale of Receivables The Company has an active receivables purchasing agreement with a bank whereby the Company can sell selected account receivables and receive between 90% to 100% of the purchase price upfront, net of applicable discount fee, and the residual amount as the receivables are collected. During 2020, the Company sold a total of $58.9 million in receivables under the program, receiving $58.0 million in cash. The outstanding purchase price component of $0.8 million was recorded in prepaid expenses and other current assets on the consolidated balance sheet at December 31, 2020. During 2019, the Company sold a total of $34.4 million in receivables under the program, receiving $32.2 million in cash. The outstanding purchase price component of $2.2 million was recorded in prepaid expenses and other current assets on the consolidated balance sheet at December 31, 2019. New Accounting Standards Adopted On January 1, 2020, the Company adopted FASB ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. The Company adopted the standard using a modified retrospective approach through a cumulative-effect adjustment to retained earnings. It recognized the cumulative effect of adopting the new credit loss standard as an adjustment to the opening balance of retained earnings as of January 1, 2020. The adoption of the standard did not have a material impact on the Company's consolidated financial statements. In December 2019, the FASB issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, as part of its initiative to reduce complexity in the accounting standards. The amendments in ASU 2019-12 eliminate certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also clarifies and simplifies other aspects of the accounting for income taxes. The amendments in ASU 2019-12 are effective for fiscal years beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period. The Company early adopted this amendment as of June 28, 2020. The adoption of the standard did not have a material impact to the Company’s condensed consolidated financial position and results of operations as well as related income tax disclosures. On January 1, 2019, the Company adopted FASB ASU 2016-02, Leases, and all related amendments ("ASC Topic 842"), under the modified retrospective approach. Consequently, periods prior to January 1, 2019 are not restated for the adoption of ASC Topic 842. In addition, it elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. Adoption of the new standard resulted in the recording of additional Right-of-Use ("ROU") assets and lease liabilities of $10.7 million and $10.9 million, respectively, as of January 1, 2019. ROU assets represent its right to use an underlying a

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations and Assets Held for Sale Discontinued Operations During the third quarter of 2019, the Company instituted a strategic shift to exit the upstream oil and gas valves market to focus on more attractive end markets. In line with that shift, during the third quarter of 2019 the Company sold its EV business and classified its DV business as held for sale. These businesses were previously part of the Energy segment. In accordance with ASC Topic 205-20, Presentation of Financial Statements - Discontinued Operations, the Company determined that the EV and DV businesses represented a strategic shift that has or will have a major effect on the Company's operations and financial results. As a result, these businesses met the conditions for discontinued operations and are recorded as such in the consolidated financial statements. Prior period comparative financial information has been reclassified to conform to this presentation. The Company reports financial results for discontinued operations separately from continuing operations in order to distinguish the financial impact of the disposal transactions from ongoing operations. Upon classifying the DV business as held for sale, the Company was required to measure the disposal group at the lower of its carrying value or fair value less expected costs to sell. The Company calculated fair value of the DV business using an income approach based on the present value of projected future cash flows. This approach incorporates several key assumptions which include the rate of revenue growth including the rate of growth used in the terminal year value, the projected operating margin, as well as the discount rate based on a weighted average cost of capital. Through this process, the Company determined that the carrying value exceeded fair value and recognized a goodwill impairment of $6.9 million and an intangible asset impairment of $1.0 million. At December 31, 2019, the Company recognized a valuation allowance of $39.8 million, to adjust the carrying value of the disposal group to its fair value less expected costs to sell. During the second quarter of 2020, the Company completed the sale of its DV business to MS Valves GmbH for negative $8.25 million and a working capital adjustment of negative $2 million at the time of closing. The transaction is subject to an earnout of 50% of net profit (only if positive) from closing through December 31, 2022. The Company has agreed to provide certain transition services for six to twelve months, depending on the nature of the services. As part of transaction the Company retained certain supplier and lease liabilities and responsibility for shutting down DV’s Mexico manufacturing facility. The Company recognized a loss of $21.6 million in 2020 from the sale of DV, including costs to sell and working capital adjustments. The following table presents the summarized components of (loss) income from discontinued operations, for the EV and DV businesses for the years ended December 31, 2020, 2019 and 2018 (in thousands): Year Ended December 31, 2020 December 31, 2019 December 31, 2018 Net revenues $ 10,055 $ 79,848 $ 162,355 Cost of revenues 26,399 105,132 145,908 Gross (loss) profit (16,344) (25,284) 16,447 Selling, general and administrative expenses 9,074 15,487 23,786 Special and restructuring charges, net (1) 17,831 85,603 4,930 Operating (loss) income (43,249) (126,374) (12,269) Other (income) expense: Interest (income), net (14) (8) (62) Other (income) expense, net 614 (378) (9) Total other (income) expense, net 600 (386) (71) (Loss) income from discontinued operations, pre tax (43,849) (125,988) (12,198) (Benefit from) provision for income taxes (8,709) (16,821) (6,161) (Loss) income from discontinued operations, net of tax $ (35,140) $ (109,167) $ (6,037) (1) The year ended December 31, 2020 includes a loss on the sale of the DV business of $21.6 million. The year ended December 31, 2019, includes a valuation allowance of $39.8 million for the DV business, loss on sale of the EV business of $37.9 million, and goodwill and intangible asset impairments related to the DV business of $7.9 million. Assets Held for Sale In addition to its businesses classified as discontinued operations, the Company has other disposal groups that meet the requirements of ASC 360-10 to be classified as held for sale in its consolidated balance sheets. In December 2019, the Company entered into a definitive agreement to dispose of its I&S business which was part of the Energy segment. The disposal group met the requirements to be classified as held for sale in the Company's consolidated balance sheet as of December 31, 2019. In December 2020, the Company determined that its Cryogenic Valves business ("Cryo") which is part of the Industrial segment constituted a disposal group that satisfied the held for sale classification criteria. In accordance with ASC 360-10, prior period results have not been restated to reflect the Cryo business as held for sale. The following table presents the balance sheet information for assets and liabilities held for sale as of December 31, 2020 and December 31, 2019 (in thousands): December 31, 2020 December 31, 2019 Discontinued Operations Other Held for Sale (1) Total Discontinued Operations (2) Other Held for Sale (1) Total Trade accounts receivable, net $ — $ — $ — $ 467 $ 9,935 $ 10,402 Inventories — 2,963 2,963 55,521 13,878 69,399 Prepaid expenses and other current assets — 48 48 2,867 616 3,483 Property, plant, and equipment, net — 162 162 6,742 6,409 13,151 Goodwill — 1,900 1,900 — 91,492 91,492 Deferred tax asset — — — 778 1,089 1,867 Other assets — — — 4,793 6,363 11,156 Valuation adjustment on classification to assets held for sale — — — (39,757) — (39,757) Classified as current (3) — 5,073 5,073 31,411 129,782 161,193 Classified as noncurrent — — — — — — Total assets held for sale $ — $ 5,073 $ 5,073 $ 31,411 $ 129,782 $ 161,193 Accounts payable $ — $ — $ — $ 8,708 $ 5,997 $ 14,705 Accrued and other current liabilities — — — 5,834 2,192 8,026 Deferred income taxes — — — 638 151 789 Other noncurrent liabilities — — — 13,931 5,838 19,769 Classified as current (3) — — — 29,111 14,178 43,289 Classified as noncurrent — — — — — — Total liabilities held for sale $ — $ — $ — $ 29,111 $ 14,178 $ 43,289 (1) Reflects the assets and liabilities of disposal groups that did not meet the criteria to be classified as discontinued operations.

Revenue Recognition

Revenue Recognition	12 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company’s revenue is derived from a variety of contracts. A significant portion of revenues are from contracts associated with the design, development, manufacture or modification of highly engineered, complex and severe environment products with customers who are either in or service the aerospace, defense, industrial and energy markets. The Company’s contracts within the defense markets are primarily with U.S. military customers. These contracts typically are subject to the Federal Acquisition Regulations ("FAR"). The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Contracts may be modified to account for changes in contract specifications and requirements. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control is transferred to the customer. Consistent with historical practice, the Company excludes from the transaction price amounts collected on behalf of third parties (e.g. taxes). Performance obligations are typically satisfied at a point in time and shipping and handling costs are treated as fulfillment costs. To determine the proper revenue recognition method for contracts for highly engineered, complex and severe environment products, which meet over-time revenue recognition criteria, the Company evaluates whether two or more contracts should be combined and whether the combined or single contract should be accounted for as more than one performance obligation. For most of the Company’s over-time revenue recognition contracts, the customer contracts with the Company to provide custom products which serve a single project or capability (even if that single project results in the delivery of multiple products) with enforceable right to payment. In circumstances where each distinct product in the contract transfers to the customer over time and the same method would be used to measure the entity’s progress toward complete satisfaction of the performance obligation to transfer each unit to the customer, the Company then applies the series guidance to account for the multiple products as a single performance obligation. In certain instances, the Company may promise to provide distinct goods or services within the over-time revenue recognition contract, in which case the Company separates the contract into more than one performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using estimated standalone selling price of each distinct good or service in the contract when not directly observable. If at the inception of the contract the period between the transfer of control of the good or service to the customer and when the customer pays for that good or service is less than a year the Company applies the practical expedient for significant financing component. Certain long-term contracts result in contract assets for unbilled receivables or contract liabilities for customer advances or deposits. Such unbilled receivables or customer advances and deposits are not considered a significant financing component because they are protective in nature for the customer or the Company. Certain of the Company’s contracts give rise to variable consideration, including penalties. The Company includes in its contract estimates a reduction to revenue for customer agreements, primarily in the large projects businesses, which contain late shipment penalty clauses whereby the Company is contractually obligated to pay consideration to customers if the Company does not meet specified shipment dates. Variable consideration is estimated using the most likely amount method or the expected value method depending on nature of the variability, and the method elected is consistently applied among performance obligations with similar uncertainties. For revenue that is recognized from products and services transferred to customers over-time, the Company uses an input measure (e.g., costs incurred to date relative to total estimated costs at completion, known as the “cost-to-cost” method) to measure progress. The Company uses the cost-to-cost measure of progress because it best depicts the transfer of control to the customer which occurs as it incurs costs on its contracts. Under the cost-to-cost measure of progress, revenue is recognized proportionally as costs are incurred. Contract costs include labor, materials and subcontractors’ costs, other direct costs and an allocation of overhead, as appropriate. Accounting for over-time contracts requires reliable estimates in order to estimate total contract revenue and costs. For these contracts, management reviews the progress and execution of the Company's performance obligations at least quarterly. Management estimates the profit on a contract as the difference between the total estimated revenue and estimate at completion ("EAC") costs and recognizes the resultant profit over the life of the contract, using the cost-to-cost EAC input method to measure progress toward complete satisfaction of a performance obligation. A change in one or more of these estimates could affect the profitability of the related contracts. Management recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating expenses or revenue. On December 31, 2020, the Company had $176.4 million of transaction price related to remaining performance obligations. It expects to recognize approximately 71% of our remaining performance obligations as revenue during 2021, 18% in 2022, and 11% thereafter. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the consolidated balance sheet. Contract assets include unbilled amounts typically resulting from over-time contracts when revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Expected credit losses are considered and allowances recorded where applicable, which result in the net amount expected to be collected. Generally, payment terms are based on milestones or shipment and billing occurs subsequent to revenue recognition, resulting in contract assets for over-time revenue recognition products. However, the Company sometimes receives advances or deposits from its customers, before revenue is recognized, resulting in contract liabilities. These assets and liabilities are reported net on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. The incremental costs of obtaining a contract are expensed when the amortization period for such contracts would have been one year or less. In order to determine revenue recognized in the period from contract liabilities, the Company first allocates revenue to the individual contract liabilities balances outstanding at the beginning of the period until the revenue exceeds that balance. If additional advances are received on those contracts in subsequent periods, it assumes all revenue recognized in the reporting period first applies to the beginning contract liabilities as opposed to a portion applying to the new advances for the period. Revenue recognized during the year ended December 31, 2020 that was included in contract liabilities as of the beginning of the year amounted to $22.4 million. The Company’s contract assets and contract liabilities as of December 31, 2020 and 2019 are as follows (in thousands): December 31, 2020 December 31, 2019 Increase/(Decrease) Contract assets: Recorded within prepaid expenses and other current assets $ 67,352 $ 52,781 $ 14,571 Recorded within other non-current assets 10,824 — 10,824 $ 78,176 $ 52,781 $ 25,395 Contract liabilities: Recorded within accrued expenses and other current liabilities $ 23,585 $ 35,007 $ (11,422) Recorded within other non-current liabilities 9,412 — 9,412 $ 32,997 $ 35,007 $ (2,010) Contract assets increased by $25.4 million. during the year ended December 31, 2020, primarily due to unbilled revenue recognized during the period for over-time revenue contracts within our Defense business and Refinery Valves business. Contract liabilities decreased by $2.0 million during the year ended December 31, 2020, primarily due to recognition of revenue against customer advances within our Defense business exceeded advances collected in current year.

Leases [Abstract]
Leases	Leases The Company leases certain office spaces, warehouses, vehicles and equipment under operating leases. Leases with an initial term of 12-months or less are not recorded on the consolidated balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. For lease agreements entered into after the adoption of ASC Topic 842, the Company combines lease and non-lease fixed components for real estate, vehicles and equipment leases. It does not combine lease and non-lease components for information technology leases. Variable lease costs are not included within the measurement of the lease liability as they are entirely variable or the difference between the portion captured within the lease liability and the actual cost will be expensed as incurred. Variable costs are contractually obligated and relate primarily to common area maintenance and taxes, which are not material to the financial statements. The Company elected the package of practical expedients permitted under the transition guidance, which allowed it to carry forward the historical lease classification, not reassess if existing contracts are or contain leases, and not reassess indirect costs for existing leases. It has elected not to recast the comparable periods and rather used the effective adoption date of the standard as the date of initial application. In determining the present value of lease payments, the Company uses the implicit borrowing rate in the lease, if available. In cases where a lease does not provide an implicit borrowing rate, it uses the incremental borrowing rate based on available information at the commencement date. As of December 31, 2020, none of its existing leases provided an implicit borrowing rate. The Company gives consideration to its debt issuances as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Additionally, it performs an entity-level financial assessment along with risk assessment by country or jurisdiction in the determination of our incremental borrowing rate. It updates its financial and risk assessments periodically. The Company reassesses lease classification and / or remeasures the lease liability in the event of the following: changes in assessment of renewal, termination or purchase option based on triggering events within our control, change in amounts probable of being owed under a residual guarantee, or contingency resolution. Certain leases include one or more options to renew or terminate a lease early. The exercise of these options is at the Company’s sole discretion. There are currently no renewal periods included in any of the leases’ respective lease terms as they are not reasonably certain of being exercised. The Company does not have any material purchase options. Certain of our lease agreements have rental payments that are adjusted periodically for inflation or that are based on usage. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The following table shows goodwill by segment as of December 31, 2020 and 2019 (in thousands): Aerospace & Defense Industrial Consolidated Goodwill as of December 31, 2019 $ 57,385 $ 214,508 $ 271,893 Impairment — (116,182) (116,182) Reclassification of Cryo to assets held for sale — (1,900) (1,900) Currency translation adjustments 189 4,944 5,133 Goodwill as of December 31, 2020 $ 57,574 $ 101,370 $ 158,944 Energy Aerospace & Defense Industrial Consolidated Goodwill as of December 31, 2018 $ 96,272 $ 57,418 $ 296,915 $ 450,605 Business divestiture — — (85,474) (85,474) Reclassification of I&S to assets held for sale (91,492) — — (91,492) Currency translation adjustments (4,780) (33) 3,067 (1,746) Goodwill as of December 31, 2019 $ — $ 57,385 $ 214,508 $ 271,893 During the year ended December 31, 2020 the Company recorded a goodwill impairment charge in the amount of $116.2 million. During the year ended December 31, 2019, the Company recorded goodwill impairments of $8.6 million related to the discontinued operations, which are excluded from the tables above which represents goodwill activity for continuing operations. No goodwill impairments were recorded related to continuing operations during the year ended December 31, 2019. Historical accumulated goodwill impairments in continuing operations prior to 2020 were immaterial. At March 29, 2020, the Company reorganized its reporting units (see Note 18, Business Segment and Geographical Information) and had its stock price drop below book value, which the Company determined were triggering events requiring an assessment of its goodwill and indefinite-lived trade names. Our asset groups did not experience a triggering event, and our long-lived assets did not suffer a decline in utility requiring a reassessment of their useful lives. Through its assessment, management determined that its long-lived assets other than goodwill were not impaired. For the assessment of goodwill as of March 29, 2020, the Company estimated the fair value of its two reporting units, Industrial and Aerospace & Defense, using an income approach based on the present value of future cash flows. The Company also utilized the implied market value method under the market approach to validate the fair value amount it obtained using a discounted cash flow model income approach which indicated a control premium. Management believes this approach was the best approximation of fair value of its reporting units in the current economic environment considering the uncertainty caused by the COVID-19 pandemic. The key assumptions utilized in our discounted cash flow model include our estimates of the rate of revenue growth and the discount rate based on a weighted average cost of capital. The estimated fair values using a discounted cash flow model were reconciled to the value indicated by the market capitalization including an assessment of the implied control premium. The relevant inputs, estimates and assumptions used in the implied market value method included our market capitalization as of March 29, 2020, and selection of a control premium. Based on our impairment assessment as of March 29, 2020, the Company determined that goodwill in the Industrial reporting unit had been impaired and, accordingly, resulted in a goodwill impairment charge of $116.2 million during the first quarter of 2020. The Company performs an impairment assessment for goodwill at the reporting unit level on an annual basis as of the end of our October month end or more frequently if circumstances warrant. Based on the annual impairment test during the fourth quarter of 2020, there was no impairment to the goodwill of our reporting units.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The significant components of our deferred income tax liabilities and assets were as follows (in thousands): December 31, 2020 2019 Deferred income tax (liabilities): Fixed Assets (12,813) (14,044) Intangible Assets (51,893) (54,032) Right of Use Lease (2,997) — Other (2,000) (3,259) Total deferred income tax liabilities (69,703) (71,335) Deferred income tax assets: Accrued expenses 5,958 5,202 Bad Debt 3,935 2,247 Equity Compensation 3,565 3,373 Inventory 4,795 7,439 Other 11,270 11,513 Net operating loss and credit carry-forward 77,533 52,577 Pension 36,532 32,901 Interest 16,022 9,836 Goodwill 7,235 — Total deferred income tax assets 166,845 125,088 Valuation allowance (125,343) (44,326) Deferred income tax asset, net of valuation allowance 41,502 80,762 Deferred income tax (liability)/asset, net $ (28,201) $ 9,427 Prior year balance of deferred tax assets as well as valuation allowance has been adjusted by an equal and offsetting amount of $30.0 million. This relates to deferred tax assets for net operating losses related to certain foreign tax jurisdictions and corresponding valuation allowances. This adjustment to the disclosure has no effect on the consolidated balance sheets, statements of (loss) income, statements of comprehensive (loss) income and statements of cash flows. The (benefit from) provision for income taxes is based on the following pre-tax (loss) income (in thousands): Year Ended December 31, 2020 2019 2018 Domestic $ (153,327) $ (45,209) $ (71,059) Foreign 59,191 35,117 47,163 (Loss) income before income taxes $ (94,136) $ (10,092) $ (23,896) The provision for income taxes consisted of the following (in thousands): Year Ended December 31, 2020 2019 2018 Current provision: Federal - U.S. $ 165 $ — $ — Foreign 6,739 17,522 11,583 State -U.S. 548 594 235 Total current provision $ 7,452 $ 18,116 $ 11,818 Deferred expense (benefit): Federal - U.S. $ 38,521 $ 8,414 $ 621 Foreign 7,250 (11,768) (1,323) State -U.S. 2,999 (86) (1,665) Total expense (benefit) deferred 48,770 (3,440) (2,367) Total provision (benefit) for income taxes $ 56,222 $ 14,676 $ 9,451 Actual income taxes reported from operations were different from those that would have been computed by applying the federal statutory tax rate to (loss) income before income taxes. The expense for income taxes differed from the U.S. statutory rate due to the following: Year Ended December 31, 2020 2019 2018 Expected federal income tax rate 21.0 % 21.0 % 21.0 % State income taxes, net of federal tax benefit (3.8) 15.5 3.8 Impairment (7.1) — — US permanent differences — (1.6) (1.0) Foreign tax rate differential 4.6 4.5 5.1 Tax reserve (0.8) (0.3) 1.3 Rate Change (0.1) 5.9 — GILTI (4.0) (3.9) (20.7) Foreign tax credit writeoff — — (45.6) Foreign-derived intangible income ("FDII") — 10.7 0.1 Prior period adjustment 0.4 44.1 4.3 Dispositions (1.0) (227.0) — Valuation Allowance (68.8) (0.5) (5.5) Other, net 0.4 (16.1) (0.8) Equity compensation (0.5) (10.8) (4.2) Research and development — 13.1 2.7 Effective tax rate (59.7) % (145.4) % (39.5) % ASC 740, Income Taxes, requires a valuation allowance to reduce deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The weight given to the potential effect of negative and positive evidence should be commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, (a) the more positive evidence is necessary and (b) the more difficult it is to support a conclusion that a valuation allowance is not needed for some portion, or all, of the deferred tax asset. Should there be a cumulative loss in recent years it is considered a significant piece of negative evidence that is difficult to overcome in assessing the need for a valuation allowance. Management assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On July 9, 2020, the US Department of the Treasury (Treasury) and Internal Revenue Service (IRS) released Final Regulations (Final Regulations) that provide guidance on the section 250 deduction for foreign-derived intangible income (FDII) and global intangible low-taxed income (GILTI). In addition, on July 20, 2020, Treasury released Proposed Regulations concerning GILTI. Based on the impact of these regulations, we believe less reliance should be placed on the US taxation of foreign earnings, which would adversely impact our ability to realize our US deferred tax assets. With the release of these Final Regulations during the third quarter, coupled with the negative evidence of cumulative losses in the US, the negative evidence outweighed the positive evidence as of the third quarter of 2020. As such, the Company has not relied on projections of future taxable income in our assessment of the realization of deferred tax assets at September 27, 2020, and recognized a valuation allowance of $42.2 million in income tax expense in the third quarter of 2020. In addition, the Company recorded a valuation allowance related to German deferred tax assets of $14.8 million in income tax expense in the fourth quarter of 2020. The Company relied solely on the expected reversal of taxable temporary differences to support the realizability of the German deferred tax assets and no reliance was placed on projections of future taxable income. As of December 31, 2020 and 2019, the Company maintained a total valuation allowance of $125.3 million and $44.3 million, respectively, which relates to foreign, federal, and state deferred tax assets as of December 31, 2020 and foreign, federal and state deferred tax assets as December 31, 2019. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as our projections for growth. The following table provides a summary of the changes in the deferred tax valuation allowance for the years ended December 31, 2020, 2019, and 2018 (in thousands): December 31, 2020 2019 2018 Deferred tax valuation allowance at January 1 $ 44,326 $ 53,531 $ 56,910 Additions 81,160 — 12,086 Acquired — 150 (15,432) Deductions (143) (9,355) (33) Deferred tax valuation allowance at December 31 $ 125,343 $ 44,326 $ 53,531 As discussed previously, the prior year balances of deferred tax assets and valuation allowance have been adjusted by equal and offsetting amounts relating to net operating losses for certain foreign tax jurisdictions and corresponding valuation allowances. The adjustments increased the ending balances of valuation allowance for 2019 and 2018 by $30.0 million and $36.0 million, respectively, offset by corresponding adjustments to the deferred tax assets. These adjustments to the disclosure have no effect to the consolidated balance sheets, statements of (loss) income, statements of comprehensive (loss) income and statements of cash flows. The Company files income tax returns in the U.S. federal, state and local jurisdictions and in foreign jurisdictions. The Company is no longer subject to examination by the Internal Revenue Service ("IRS") for years prior to 2017 and is no longer subject to examination by the tax authorities in foreign and state jurisdictions prior to 2006, with the exception of net operating loss carryforwards. The Company is currently under examination for income tax filings in various foreign jurisdictions. As of December 31, 2020, the Company had US net operating losses of $12.7 million, US tax credits of $20.8 million, foreign net operating losses of $175.8 million, state net operating losses of $107.1 million and state tax credits of $2.3 million. As of December 31, 2019, the Company had US tax credits of $15.9 million, foreign net operating losses of $128.3 million, state net operating losses of $68.8 million and state tax credits of $2.0 million. The foreign tax credits, if not utilized, will expire in 2026-2037. A portion of the foreign net operating losses ($81.1 million) expire at various dates through 2035; the remainder have an unlimited carryforward period. The federal net operating losses have an unlimited carryforward period. The state net operating losses and state tax credits, if not utilized, will expire at various dates through 2039. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law as a result of the COVID-19 pandemic, and contains among other things, numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. The Company has evaluated the current legislation and at this time does not anticipate the CARES Act to have a material impact on its financial statements. As of December 31, 2020, the liability for uncertain income tax positions was approximately $1.1 million. Approximately $0.7 million as of December 31, 2020 represents the amount that if recognized would affect the Company’s effective income tax rate in future periods. The Company does not expect the unrecognized tax benefits to change over the next 12 months. The table below does not include interest and penalties of $0.1 million and $0.0 million as of December 31, 2020 and 2019, respectively. The following is a reconciliation of the Company’s liability for uncertain income tax positions for the years ended December 31, 2020, 2019 and 2018 (in thousands): December 31, 2020 2019 2018 Balance beginning January 1 $ 630 $ 593 $ 3,014 Additions/(reductions) for tax positions of prior years 448 — (460) Additions/(reductions) based on tax positions related to current year — 37 (340) Acquired uncertain tax position balance — — (512) Settlements — — (1,103) Lapse of statute of limitations — — (6) Balance ending December 31 $ 1,078 $ 630 $ 593 Undistributed earnings of our foreign subsidiaries amounted to nil and $196.4 million at December 31, 2020 and December 31, 2019, respectively. The undistributed earnings of our foreign subsidiaries (except for one of our China subsidiaries) are considered to be indefinitely reinvested unless earnings can be repatriated in a tax efficient manner and accordingly, no provision for income taxes has been recorded (except for withholding taxes related to the forementioned China subsidiary). Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable because of the complexity of laws and regulations, the varying tax treatment of alternative repatriation scenarios, and the variation due to multiple potential assumptions relating to the timing of any future repatriation.

Debt Disclosure [Abstract]
Financing Arrangements	Financing Arrangements Debt Long-term debt consisted of the following (in thousands): December 31, 2020 2019 Term Loan at interest rates ranging from 4.3%-5.2% in 2020 and 5.24%-6.0% in 2019 $ 492,038 $ 653,850 Line of Credit at interest rates ranging from 3.6%-7.2% in 2020 and 5.65%-8.00% in 2019 27,900 — Total Principal Debt Outstanding 519,938 653,850 Less: Term Loan Debt Issuance Costs 12,050 17,553 Total Long-Term Debt, net $ 507,888 $ 636,297 2021 2022 2023 2024 2025 Thereafter Minimum principal payments $ — $ 27,900 $ — $ 492,038 $ — $ — On December 11, 2017, the Company entered into a secured credit agreement (the "Credit Agreement"), which provides for a $150.0 million revolving line of credit with a five year maturity and a $785.0 million term loan with a seven year maturity which was funded in full at closing of the FH acquisition. The Credit Agreement replaced and terminated the Company’s prior credit agreement, dated as of May 11, 2017 (the "Prior Credit Agreement"). The Prior Credit Agreement, under which the Company had borrowings of $273.5 million outstanding, was terminated on December 11, 2017 and replaced by the Credit Agreement. The term loan requires quarterly principal payments of 0.25% of initial aggregate principal amount beginning March 29, 2018 with the balance due at maturity. During 2020, the Company paid down $161.8 million on its term loan from proceeds received through the sale of the I&S business. In March 2020, the Company drew down $80 million on its line of credit due to concerns about possible disruptions to global capital markets stemming from COVID-19. The Company has since paid down a portion of draw down for a remaining balance of $27.9 million as of December 31, 2020. During 2019, the Company paid down its term loan by $123.3 million primarily with divestiture-related proceeds thereby satisfying all future amortization obligations (previously $2.0 million per quarter) until 2024 under the Credit Agreement. Additional loans of up to $150.0 million (plus the amount of certain voluntary prepayments) and an amount subject to compliance with a first lien net leverage ratio of 6.50 to 1.00 may be made available under the Credit Agreement upon request of the Company subject to specified terms and conditions. The Company may repay any borrowings under the Credit Agreement at any time, subject to certain limited and customary restrictions stated in the Credit Agreement; provided, however, that if the Company prepays all or any portion of the term loan in connection with a repricing transaction on or prior to the 6-month anniversary of the origination date, the Company must pay a prepayment premium of 1.0% of the aggregate principal amount of the term loan so prepaid. The Company incurred $23.9 million of debt issuance costs associated with the term loan which have been recorded as a debt discount within long-term debt, and $5.2 million of fees associated with the revolver which have been recorded in other assets. The Company had $30.4 million and $34.3 million in letters of credit issued under the Credit Agreement as of December 31, 2020 and December 31, 2019, respectively. The Company recorded non-cash interest expense of $4.1 million, $3.9 million, and $3.9 million for the years ended December 31, 2020, 2019 and 2018, respectively, related to the amortization of its deferred financing costs described above. The Credit Agreement revolving line of credit facility matures on December 11, 2022 whereas the term loan facility matures on December 11, 2024. The Company's outstanding debt balances are characterized as Level 2 financial instruments. As of December 31, 2020, the estimated fair value of its gross debt (before netting debt issuance costs) was $517.3 million, or $2.6 million under its carrying value of $519.9 million. During the first quarter of 2020, the Company amended its term loan to lower the interest rate associated with the applicable margin calculation. The new terms lower the interest rate on the term loan from LIBOR plus an applicable margin of 3.5% to LIBOR plus an applicable margin of 3.25%, based on its existing corporate family rating from Moody's. The applicable margin reduces to LIBOR plus an applicable margin of 3.0%, with a corporate family rating from Moody's of B1 or better. As part of the debt repricing, the Company's outstanding loan balance was reallocated amongst the lender group. The Company evaluated the changes in outstanding loan balance for each individual lender to determine the amount of capitalized debt issuance costs that required adjustment. Through this exercise, the Company determined that certain creditors under the original term loan did not participate in this refinancing transaction and ceased being creditors of the Company. As a result, the Company recorded a debt extinguishment loss of $3.5 million in the first quarter of 2020 which is recorded to Special and restructuring (recoveries) charges, net, on the consolidated statements of (loss) income. For the remainder of the creditors, this transaction was accounted for as a modification. The Company accounted for the amendment pursuant to ASC 470, Debt, and third-party costs of $0.2 million related to this transaction were expensed and $0.3 million of lender fees were recorded as a reduction to debt representing deferred issuance costs. Financial Instruments As of December 31, 2020 and December 31, 2019, the Company had restricted cash balances of $1.2 million and $1.2 million, respectively. These balances are recorded within prepaid expenses and other current assets on the consolidated balance sheets, and are included within cash, cash equivalents and restricted cash in the consolidated statements of cash flows. Effective July 2019, the Company entered into a cross-currency swap agreement to hedge its net investment in non-U.S. subsidiaries against future volatility in exchange rates between the U.S. dollar and the Euro. The cross-currency swap agreement is pursuant to an ISDA Master Agreement with Deutsche Bank AG. The three-year cross-currency swap has a fixed notional value of $100.0 million at an annual rate of 2.4065% and a maturity date of July 12, 2022. At inception, the cross-currency swap was designated as a net investment hedge. This hedging agreement mitigates foreign currency exchange rate exposure on the Company's net investment in Euro denominated subsidiaries and is not for speculative trading purposes. The net investment hedge was deemed effective as of year-end. Effective April 2018, the Company entered into an interest rate swap pursuant to an ISDA Master Agreement with Citizens Bank, National Association. The four-year interest rate swap has a fixed notional value of $400.0 million with a 1% LIBOR floor (in line with the Company's credit agreement) and a maturity date of April 12, 2022. The fixed rate of interest paid by the Company is comprised of its current credit spread of 325 basis points plus 2.6475% for a total interest rate of 5.8975%. The ISDA Master Agreement, together with its related schedules, contain customary representations, warranties and covenants. The Company has designated the interest rate swap as a qualifying hedging instrument and is treating it as a cash flow hedge for accounting purposes pursuant to ASC Topic 815, Derivatives and Hedging. The aggregate net fair value of the interest rate swap and cross currency swap as of December 31, 2020 and December 31, 2019 are summarized in the table below (in thousands): Significant Other Observable Inputs Level 2 2020 2019 Derivative asset $ 2,359 $ 476 Derivative liabilities $ (17,139) $ (9,168) December 31, 2020 balances are recorded in other non-current liabilities of $(10.6) million, accrued expenses and other current liabilities of $(6.5) million, and prepaid expenses and other current assets of $2.4 million on the Company's consolidated balance sheets as of December 31, 2020. December 31, 2019 balances are recorded in other non-current liabilities of $(5.1) million, accrued expenses and other current liabilities of $(4.0) million, and prepaid expenses and other current assets of $0.5 million. The amount of gain (loss) recognized in other comprehensive (loss) income ("OCI") and reclassified from accumulated other comprehensive (loss) income ("AOCI") to income are summarized below (in thousands): Year Ended December 31, 2020 December 31, 2019 Amount of gain (loss) recognized in OCI $ (5,433) $ (8,580) Amount of gain (loss) reclassified from AOCI into earnings (interest expense, net) $ (6,162) $ (1,583) At December 31, 2020, amounts expected to be reclassified from AOCI into interest expense in the next 12 months is a loss of $6.5 million.

Share-Based Compensation

Share-Based Compensation	12 Months Ended
	Dec. 31, 2020
Share-based Payment Arrangement, Noncash Expense [Abstract]
Share-Based Compensation	Share-Based Compensation The Company has three share-based compensation plans as of December 31, 2020: (1) the 2019 Stock Option and Incentive Plan (the "2019 Plan"), (2) the 2014 Stock Option and Incentive Plan (the "2014 Plan"), and (3) the Amended and Restated 1999 Stock Option and Incentive Plan (the "1999 Plan"). The 2019 Plan was adopted by its Board of Directors (subject to shareholder approval) on February 20, 2019 and approved by its shareholders at the Company's annual meeting on May 9, 2019. As of May 9, 2019, no new awards will be granted under either the 2014 Plan or the 1999 Plan. As a result, any shares subject to outstanding awards under the 2014 Plan and the 1999 Plan that expire, are canceled or otherwise terminate, or are withheld to satisfy tax withholding obligations will not be available for award grant purposes under the 2019 Plan. All plans permit the grant of the following types of awards to its officers, other employees and non-employee directors: incentive stock options, nonqualified stock options, deferred stock awards, restricted stock awards, restricted stock unit ("RSU") awards, unrestricted stock awards, performance share awards, cash based awards, stock appreciation rights ("SARs") and dividend equivalent rights. The 2019 Plan provides for the issuance of up to 1,000,000 shares of common stock (subject to adjustment for stock splits and similar events). Under the 2019 Plan, shares issued for all awards count against the aggregate share limit as 1.0 share for every share actually issued. All stock options and RSUs granted under the 1999 Plan are either 100% vested or have been terminated. RSUs granted under the 2014 Plan and the 2019 Plan generally vest within three years. RSUs will be settled in shares of the Company's common stock. As of December 31, 2020, there were 457,953 shares available for grant under the 2019 Plan. As of December 31, 2020, there were 666,785 stock options (including the CEO stock option award noted below) and 744,925 RSUs outstanding. The Company measures the cost of all share-based payments, including stock options, at fair value on the grant date and recognizes this cost in the consolidated statements of (loss) income, net of actual forfeitures. Compensation expense related to its share-based plans for the years ended December 31, 2020, 2019 and 2018 was $5.7 million, $5.4 million and $5.0 million respectively. During 2020, expenses related to share-based compensation were recorded as follows: $5.4 million in selling, general and administrative expenses, $0.1 million in special charges related to the sale of the I&S business, and $0.2 million in discontinued operations related to the sale of the DV business. The special charges and discontinued operations costs relate to the accelerated vesting of awards as a result of the sale transactions. As of December 31, 2020, there was $5.4 million of total unrecognized compensation cost related to the Company's outstanding share-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.6 years. This compares to $8.1 million for 2019 and $7.6 million for 2018, respectively. Stock Options During the year ended December 31, 2020, there were no stock option awards granted for the purchase of shares of the Company's common stock, compared with 153,726 in 2019 and 127,704 in 2018. On April 9, 2013, the Company granted a stock option to purchase 200,000 shares of common stock to its President and Chief Executive Officer at an exercise price of $41.17 per share. This award included a service period and a market performance vesting condition. In 2014, certain of these targets were achieved and 150,000 shares vested and remain exercisable. The remaining 50,000 shares were canceled in 2018 as the performance condition was not satisfied. On March 5, 2014, the Company granted a stock option to purchase 100,000 shares of common stock to its President and Chief Executive Officer at an exercise price of $70.42 per share. This option award includes a service period and market performance vesting conditions which were not met and all 100,000 shares were canceled in 2018. The Company uses the Black Scholes pricing model to fair value the option awards. The average fair value of stock options granted during the years ended December 31, 2019, and 2018 of $11.84 and $14.68, respectively, was estimated using the following weighted-average assumptions: Year Ended December 31, 2019 2018 Risk-free interest rate 2.6 % 2.5 % Expected life (years) 4.3 4.3 Expected stock volatility 38.1 % 37.2 % Expected dividend yield — % — % There were no stock option grants during 2020. Restricted Stock Units The Company accounts for RSU awards by expensing the weighted average fair value to selling, general and administrative expenses ratably over vesting periods generally ranging up to three years. During the years ended December 31, 2020, December 31, 2019 and December 31, 2018 it granted 616,612, 205,291 and 167,480 RSUs, respectively, with weighted average fair values of $12.88, $32.92 and $42.87 per RSU award, respectively. On April 2, 2020, the Company granted 44,511 RSUs to its Senior Vice President and Chief Financial Officer as an inducement RSU award upon his joining the Company. This award was granted outside the 2019 Plan pursuant to applicable New York Stock Exchange rules and vests ratably over a three year period. During 2020, 2019, and 2018, the Company granted performance-based RSUs as part of the overall mix of RSU awards. In 2020, these performance-based RSU Awards include metrics for achieving Adjusted Operating Margin and Adjusted Measurement Cash Flow with target payouts ranging from 0% to 200%. In 2019, these performance-based RSUs included metrics for achieving adjusted operating margin and adjusted free cash flow with the same target payouts. In 2018 and prior years, these performance-based RSUs included metrics for achieving return on invested capital and adjusted operating margin with the same target payouts. Of the different performance-based RSU tranches, the Company anticipates approximately 29% overall achievement and probability to vest. Of the 616,612 RSUs granted during 2020, 109,278 are performance-based RSU awards. This compares to 67,362 and 48,080 performance-based RSU awards granted in 2019 and 2018, respectively. The CIRCOR Management Stock Purchase Plan ("MSPP"), which is a component of all three of the Company's share-based compensation plans, provides that eligible employees may elect to receive RSUs in lieu of all or a portion of their pre-tax annual incentive bonus and, in some cases, make after-tax contributions in exchange for RSUs (“RSU MSPs”). Each RSU MSP represents a right to receive one share of the Company's common stock after a three-year vesting period. RSU MSPs are granted at a discount of 33% from the fair market value of the shares of common stock on the date of grant. This discount is amortized as compensation expense, to selling, general and administrative expenses, over a four-year period. There were no RSU MSPs granted during 2020. RSU MSPs totaling 56,379 and 34,937 with per unit discount amounts representing fair values of $11.10 and $14.06, respectively, were granted under the MSPP during the years ended December 31, 2019 and December 31, 2018, respectively. A summary of the status of all stock options and RSU awards granted to employees and non-employee directors as of December 31, 2020 and changes during the year are presented in the table below: December 31, 2020 Stock Options RSU Awards RSU MSPs Shares Weighted Shares Weighted Shares Weighted Options and awards outstanding at beginning of period 712,500 $ 43.76 274,959 $ 38.51 106,602 $ 28.06 Granted — $ — 616,612 $ 12.88 — $ — Exercised (3,010) $ 38.89 (86,764) $ 37.32 (24,670) $ 39.58 Forfeited (9,704) $ 34.00 (138,180) $ 28.14 (3,634) $ 23.48 Expired (33,001) $ 56.26 — — — — Options and awards outstanding at end of period 666,785 $ 43.31 666,627 $ 17.11 78,298 $ 24.99 Options and awards exercisable at end of period 539,304 $ 44.99 892 $ 42.62 1,469 $ 40.86 The weighted average contractual term for stock options outstanding and exercisable as of December 31, 2020 was 3.1 years and 2.7 years, respectively.

Retirement Benefits, Description [Abstract]
Retirement Plans	Retirement Plans U.S. Contribution Plan The Company offers a savings plan to eligible U.S. employees. The plan is intended to qualify under Section 401(k) of the Internal Revenue Code. Substantially all of its U.S. employees are eligible to participate in the 401(k) savings plan. Participating employees may defer a portion of their pre-tax compensation, as defined, but not more than statutory limits. Under this plan, the Company matches a specified percentage of employee contributions, and are able to make a discretionary core contribution, subject to certain limitations. For the first part of 2018, it contributed 50% of the amount contributed by the employee, up to a maximum of 5% of the employee’s earnings. The Company's matching contributions vested at a rate of 20% per year of service, with full vesting after five years of service. Effective August 28, 2018, the Company had a 401(k) benefit update, wherein the Company contributed 100% of the amount contributed by the employee, up to a maximum of 4% of the employee's earnings. Matching contributions under the updated 401(k) benefit plan vest 0% after one year, 50% after two years, and full vesting after three years of service. In the first quarter of 2020, the Company temporarily suspended the 401(k) match for certain employee populations for the year. In the first quarter of 2021 the Company reinstated the temporarily suspended 401(k) match. The cost of the Company's 401(k) plan is outlined below (in thousands): Year Ended December 31, 2020 2019 2018 Cost of 401(k) plan $ 458 $ 3,428 $ 1,847 Pension & Other Post-Retirement Benefit Obligations The Company also sponsors various defined benefit plans, and other post-retirement benefits plans, including health and life insurance, for former employees of an acquired business. These plans include significant benefit obligations which are calculated based on actuarial valuations. Key assumptions are made in determining these obligations and related net periodic benefit costs, including discount rates, mortality, and expected long-term return on plan assets. The Company maintains a qualified noncontributory defined benefit pension plan, a nonqualified, noncontributory defined benefit supplemental pension plan, and other post-retirement benefit plans, including health and life insurance in the U.S. which are frozen. To date, the supplemental and the other post-retirement benefits plans remain unfunded. Outside of the U.S., the Company sponsors various funded and unfunded defined benefit plans. The obligations are primarily attributed to a partially funded plan in Germany and a fully funded plan in the U.K. During fiscal year 2020, the Company made cash contributions of approximately $0.8 million to its U.S. plans and $4.1 million to its foreign plans. In 2021, it expects to make defined benefit plan contributions based on the minimum required funding in accordance with statutory requirements (approximately $1.1 million in the U.S. and approximately $3.9 million for its foreign plans). The estimates for plan funding for future periods may change as a result of the uncertainties concerning the return on plan assets, the number of plan participants, and other changes in actuarial assumptions. The Company anticipates fulfilling these commitments through the generation of cash flow from operations. The components of net periodic benefit cost for the postretirement plans were as follows (in thousands): Pension Benefits Other Post-retirement Benefits Year Ended December 31, Year Ended December 31, 2020 2019 2018 2020 2019 2018 Components of net periodic benefit cost: Service cost $ 2,812 $ 2,694 $ 2,993 $ 3 $ 2 $ 1 Interest cost 6,958 10,061 9,164 262 359 336 Expected return on assets (11,731) (11,979) (15,418) — — — Net periodic benefit cost (1,961) 776 (3,261) 265 361 337 Net loss (gain) amortization 279 441 153 — (32) — Prior service cost amortization 15 15 — — — — Total amortization 294 456 153 — (32) — Net periodic benefit cost $ (1,667) $ 1,232 $ (3,108) $ 265 $ 329 $ 337 The weighted average assumptions used in determining the net periodic benefit cost and benefit obligations for the post-retirement plans are shown below: Pension Benefits Other Post-retirement Benefits Year Ended December 31, Year Ended December 31, 2020 2019 2018 2020 2019 2018 Net periodic benefit cost: Discount rate – U.S. 2.83% 3.93% 3.27% 3.05% 4.10% 3.48% Discount rate – Foreign 1.24% 2.00% 1.97% N/A N/A N/A Expected return on plan assets - U.S. 5.50% 6.25% 7.00% N/A N/A N/A Expected return on plan assets - Foreign 2.95% 3.7% 3.53% N/A N/A N/A Rate of compensation increase - Foreign 3.20% 3.15% 3.11% N/A N/A N/A Benefit obligations: Discount rate – U.S. 1.93% 2.83% 3.93% 2.26% 3.05% 4.10% Discount rate – Foreign 0.82% 1.24% 2.00% N/A N/A N/A Rate of compensation increase - Foreign 3.20% 3.09% 3.14% N/A N/A N/A The amounts reported for net periodic benefit cost and the respective benefit obligation amounts are dependent upon the actuarial assumptions used. The Company reviews historical trends, future expectations, current market conditions, and external data to determine the assumptions. The actuarial assumptions used to determine the net periodic pension cost are based upon the prior year’s assumptions used to determine the benefit obligation. Effective with fiscal year 2018, the Company changed the method used to estimate the service and interest cost components of the net periodic benefit costs for all of its plans in the U.S., U.K., and Germany. The new method uses the spot yield curve approach to estimate the service and interest costs by applying the specific spot rates along the yield curve used to determine the benefit obligations to relevant projected cash outflows. The Company changed to the new method to provide a more precise measure of interest and service costs by more closely correlating the application of the discrete spot yield curve rates with the projected benefit cash flows. Prior to fiscal year 2018, the service and interest costs were determined using a single weighted-average discount rate used to measure the benefit obligation at the measurement date. Assumed health care cost trend rates pre-65 trend at December 31, 2020 and 2019 were 6.5% and 6.8%, respectively. The rate to which the cost trend rate is assumed to decline (the ultimate trend rate) for December 31, 2020 and 2019 were 4.5% and 4.5%, respectively, and the years that the rate reaches the ultimate trend rate were 2029 and 2028, respectively. Assumed health care cost trend rates post-65 trend at December 31, 2020 and 2019 were 6.5% and 6.8%, respectively. The rate to which the cost trend rate is assumed to decline (the ultimate trend rate) for December 31, 2020 and 2019 were 4.5% and 4.5%, respectively, and the year that the rate reaches the ultimate trend rate were 2029 and 2028, respectively. In selecting the expected long-term return on assets for the qualified and foreign plans, the Company considered the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of these plans. It, with input from the plans’ professional investment managers and actuaries, also considered the average rate of earnings expected on the funds invested or to be invested to provide plan benefits. This process included determining expected returns for the various asset classes that comprise the plans’ target asset allocation. This basis for selecting the long-term return on assets is consistent with the prior year. Using generally accepted diversification techniques, the plans’ assets, in aggregate and at the individual portfolio level, are invested so that the total portfolio risk exposure and risk-adjusted returns best meet the plans’ long-term benefit obligations to employees. Plan asset allocations are reviewed periodically and rebalanced to achieve target allocation among the asset categories when necessary. This included considering the pension asset allocation and the expected returns likely to be earned over the life of the plans. The funded status of the defined benefit post-retirement plans and amounts recognized in the consolidated balance sheets, measured as of December 31, 2020 and December 31, 2019 were as follows (in thousands): Pension Benefits Other Post-retirement Benefits December 31, December 31, 2020 2019 2020 2019 Change in projected benefit obligation: Balance at beginning of year $ 382,179 $ 363,334 $ 10,193 $ 10,276 Service cost 2,812 2,694 3 2 Interest cost 6,958 10,061 262 359 Amendments 12 — — — Actuarial loss (gain) (1) 30,833 37,243 828 (12) Exchange rate loss (gain) 12,541 (1,692) — — Benefits paid (22,501) (24,533) (393) (432) Settlement payments — (3,451) — — Curtailments (2) — (1,477) — — Balance at end of year $ 412,834 $ 382,179 $ 10,893 $ 10,193 Change in fair value of plan assets: Balance at beginning of year $ 235,297 $ 210,993 $ — $ — Actual return on assets 29,624 46,665 — — Exchange rate gain 895 935 — — Benefits paid (22,501) (24,533) (393) (432) Settlement payments — (3,451) — — Employer contributions 4,506 4,688 393 432 Fair value of plan assets at end of year (3) $ 247,821 $ 235,297 $ — $ — Funded status: Excess of benefit obligation over the fair value of plan assets $ (165,013) $ (146,882) $ (10,893) $ (10,193) Pension plan accumulated benefit obligation (“ABO”) $ 412,834 $ 382,179 N/A N/A (1) The changes in benefit obligations were primarily drive by changes in discount rates in both US and foreign obligations.

Commitments and Contingencies Disclosure [Abstract]
Contingencies, Commitments And Guarantees	Contingencies, Commitments and Guarantees Legal Proceedings The Company is subject to various legal proceedings and claims pertaining to matters such as product liability or contract disputes. The Company is also subject to other proceedings and governmental inquiries, inspections, audits or investigations pertaining to issues such as tax matters, patents and trademarks, pricing, contractual issues, business practices, governmental regulations, employment and other matters. Although the results of litigation and claims cannot be predicted with certainty, the Company expects that the ultimate disposition of these matters, to the extent not previously provided for, will not have a material adverse effect, individually or in the aggregate, on its business, financial condition, results of operations or liquidity. Asbestos-related product liability claims continue to be filed against two of the Company's subsidiaries: CIRCOR Instrumentation Technologies, Inc. (f/k/a Hoke, Inc.) (“Hoke”), the stock of which the Company acquired in 1998 and Spence Engineering Company, Inc., the stock of which the Company acquired in 1984. The Hoke subsidiary was divested in January 2020 through the sale of the I&S business. However, the Company has indemnified the buyer for asbestos-related claims that are made against Hoke. Due to the nature of the products supplied by these entities, the markets they serve and the Company's historical experience in resolving these claims, the Company does not expect that these asbestos-related claims will have a material adverse effect on the financial condition, results of operations or liquidity of the Company. Standby Letters of Credit The Company executes standby letters of credit, which include bank guarantees, bid bonds and performance bonds, in the normal course of business to ensure its performance or payments to third parties. The aggregate notional value of these instruments was $39.3 million at December 31, 2020 of which $30.4 million were syndicated under the Credit Agreement and $42.0 million at December 31, 2019 of which $34.3 million were syndicated under the Credit Agreement. The Company's historical experience with these types of instruments has been good and no claims have been paid in the current or past several fiscal years. The Company believes that the likelihood of demand for payments relating to the outstanding instruments is remote. These instruments generally have expiration dates ranging from less than 1 month to 5 years from December 31, 2020. The following table contains information related to standby letters of credit instruments outstanding as of December 31, 2020 (in thousands): Term Remaining Maximum Potential 0–12 months $ 26,055 Greater than 12 months 13,247 Total $ 39,302 Commercial Contract Commitment As of December 31, 2020, the Company had approximately $94.0 million of commercial contract commitments related to open purchase orders. Insurance The Company maintains insurance coverage of a type and with such limits as it believe are customary and reasonable for the risks it faces and in the industries in which it operates. While many of its policies do contain a deductible, the amount of such deductible is typically not material. The accruals for insured liabilities are not discounted and take into account these deductibles and are based on claims filed and reported as well as estimates of claims incurred but not yet reported.

Guarantees And Indemnification Obligations [Abstract]
Guarantees And Indemnification Obligations	Guarantees and Indemnification obligations As permitted under Delaware law, we have agreements whereby we indemnify certain of our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited. However, we have directors and officers liability insurance policies that limit our exposure for events covered under the policies and should enable us to recover a portion of any future amounts paid. As a result of the coverage under these insurance policies, we believe the estimated fair value of these indemnification agreements is minimal and, therefore, have no liabilities recorded from those agreements as of December 31, 2020. We record provisions for the estimated cost of product warranties, primarily from historical information, at the time product revenue is recognized. While we engage in extensive product quality programs and processes, our warranty obligation is affected by product failure rates, utilization levels, material usage, service delivery costs incurred in correcting a product failure, and supplier warranties on parts delivered to us. Should actual product failure rates, utilization levels, material usage, service delivery costs or supplier warranties on parts differ from our estimates, revisions to the estimated warranty liability would be required. Our warranty liabilities are included in accrued expenses and other current liabilities on our consolidated balance sheets. The following table sets forth information related to our product warranty reserves for the years ended December 31, 2020 and 2019 (in thousands): December 31, 2020 2019 Balance beginning January 1 $ 1,642 $ 2,860 Provisions 2,825 1,894 Claims settled (2,313) (2,830) Acquired reserves/other — (11) Currency translation adjustment 52 (271) Balance ending December 31 $ 2,206 $ 1,642 Warranty obligations of $2.2 million as of December 31, 2020 increased $0.6 million from $1.6 million as of December 31,

Segment Reporting [Abstract]
Segment Information	Business Segment and Geographical Information The Company's reportable segments have been identified in accordance with ASC Topic 280-10-50 through its evaluation of how it engages in business activities to earn revenues and incur expenses, which operating results are regularly reviewed by its chief operating decision maker (“CODM”) to assess performance and make decisions about resources to be allocated, and the availability of discrete financial information. CIRCOR’s reportable segments are generally organized based upon the end markets it sells its products and services into. No individual operating segments have been aggregated for purposes of determining the reportable segments. The reporting segments are Industrial and Aerospace & Defense. During the quarter ended March 29, 2020, the Company divested its Instrumentation & Sampling business, which was previously part of the Energy segment. In light of this divestiture, effective March 29, 2020, the Company realigned its segments by eliminating the Energy segment and moving the remaining businesses into the Industrial segment. Following the Q1 2020 realignment the new reporting segments are Industrial and Aerospace & Defense, which is the level at which the CODM regularly reviews operating results and makes resource allocation decisions. The current and prior periods are reported under this new segment structure. Each reporting segment is individually managed, as each requires different technology and marketing strategies, and has separate financial results that are reviewed by the Company's CODM. The CODM evaluates segment performance and determines how to allocate resources utilizing, among other data, segment operating income. Segment operating income excludes special and restructuring charges, net. In addition, certain administrative expenses incurred at the corporate level for the benefit of the reporting segments are allocated to the segments based upon specific identification of costs, employment related information or net revenues. Each segment contains related products and services particular to that segment. Corporate is reported on a net “after allocations” basis. Inter-segment intercompany transactions affecting net operating profit have been eliminated within the respective reportable segments. The amounts reported in the Corporate expenses line item in the following table consists primarily of the following: compensation and fringe benefit costs for executive management and other corporate staff; Board of Director compensation; corporate development costs (relating to mergers and acquisitions); human resource development and benefit plan administration expenses; legal, accounting and other professional and consulting costs; facilities, equipment and maintenance costs; and travel and various other administrative costs related to the corporate office and respective functions. The above costs are incurred in the course of furthering the business prospects of the Company and relate to activities such as: implementing strategic business growth opportunities; corporate governance; risk management; tax; treasury; investor relations and shareholder services; regulatory compliance; strategic tax planning; and stock transfer agent costs. The Company's CODM evaluates segment operating performance using segment operating income. Segment operating income is defined as GAAP operating income excluding intangible amortization and amortization of fair value step-ups of inventory and fixed assets from acquisitions completed subsequent to December 31, 2011, the impact of restructuring related inventory write-offs, impairment charges and special charges or gains. The Company also refers to this measure as adjusted operating income. The Company uses this measure because it helps management understand and evaluate the segments’ core operating results and facilitate comparison of performance for determining incentive compensation achievement. The following table presents certain reportable segment information (in thousands): As of and for the year ended December 31, 2020 2019 2018 Net revenues Industrial $ 505,449 $ 691,688 $ 776,453 Aerospace & Defense 267,822 272,625 237,017 Consolidated revenues $ 773,271 $ 964,313 $ 1,013,470 Segment income Aerospace & Defense - Segment Operating Income 59,093 52,480 36,047 Industrial - Segment Operating Income 39,823 90,789 104,831 Corporate expenses (31,285) (33,469) (39,011) Subtotal 67,631 109,800 101,867 Special restructuring charges, net 4,945 5,186 5,848 Special other (recoveries) charges, net (39,248) 17,686 13,061 Special and restructuring (recoveries) charges, net (34,303) 22,872 18,909 Restructuring related inventory (recoveries) charges, net (250) (820) 346 Amortization of inventory step-up — — 6,600 Acquisition amortization 42,463 45,715 47,310 Acquisition depreciation 3,985 4,352 7,049 Impairment charges 116,182 — — Restructuring, impairment and other cost, net 162,380 49,247 61,305 Consolidated Operating (Loss) Income (60,446) 37,681 21,653 Interest Expense, net 34,219 48,609 52,975 Other Expense (Income), net (529) (836) (7,426) (Loss) income from continuing operations before income taxes $ (94,136) $ (10,092) $ (23,896) Identifiable assets Industrial $ 1,378,710 $ 1,760,926 $ 2,161,678 Aerospace & Defense 450,597 426,405 399,102 Corporate (698,779) (716,386) (769,168) Consolidated Identifiable assets $ 1,130,528 $ 1,470,945 $ 1,791,612 Capital expenditures Industrial $ 7,201 $ 7,523 $ 14,627 Aerospace & Defense 4,400 4,376 4,739 Corporate 466 1,074 1,787 Consolidated Capital expenditures $ 12,067 $ 12,973 $ 21,153 Depreciation and amortization Industrial $ 50,945 $ 57,576 $ 63,724 Aerospace & Defense 12,492 11,531 10,937 Corporate 610 529 750 Consolidated Depreciation and amortization $ 64,047 $ 69,636 $ 75,411 The total assets for each reportable segment have been reported as the Identifiable Assets for that segment, including inter-segment intercompany receivables, payables and investments in other CIRCOR companies. Identifiable assets reported in Corporate include both corporate assets, such as cash, deferred taxes, prepaid and other assets, fixed assets, as well as the elimination of all inter-segment intercompany assets. The elimination of intercompany assets results in negative amounts reported in Corporate for Identifiable Assets. Corporate Identifiable Assets after elimination of intercompany assets were $12.1 million, $18.9 million, and $23.8 million as of December 31, 2020, 2019 and 2018, respectively. The following tables present net revenue and long-lived assets by geographic area. The net revenue amounts are based on shipments to each of the respective areas (in thousands).

This error impacted other comprehensive income (loss). Specifically, other comprehensive income (loss) was overstated by $2.2 million for fiscal 2018, and understated by $2.2 million for the first quarter of 2019. The Company determined that these adjustments were not material to the prior periods or the Company's 2018 goodwill impairment analyses. These items were adjusted in 2019.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended

Accounting Policies [Abstract]
Cash, Cash Equivalents, and Short-term Investments [Text Block]	Cash and Cash Equivalents The Company's cash equivalents are invested in time deposits of financial institutions, and it has established guidelines relative to credit ratings, diversification and maturities that are intended to maintain safety and liquidity. Cash equivalents include highly liquid investments with maturity periods of three months or less when purchased. Restricted Cash Restricted cash represents cash that is legally restricted as to withdrawal or usage and includes amounts required to be maintained in relation to employment laws in certain jurisdictions. Other Assets
Principles Of Consolidation And Basis Of Presentation	Principles of Consolidation and Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of CIRCOR and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or divested are included in the consolidated financial statements from the date of acquisition or up to the date of disposal. Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation, including the results of discontinued operations and reportable segment information. These reclassifications have no effect on the previously reported net (loss) income. Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. Some of the more significant estimates, some of which are impacted by management’s estimates and assumptions regarding the effects of the COVID-19 pandemic, relate to recoverability of goodwill and indefinite-lived trade names, estimated total costs for ongoing long-term revenue contracts where transfer of control occurs over time, inventory valuation, share-based compensation, amortization and impairment of long-lived assets, income taxes (including valuation allowance), fair value of disposal group, pension benefits obligations, acquisition accounting, penalty accruals for late shipments, asset valuations, and product warranties. While management believes that the estimates and assumptions used in the preparation of the financial statements are appropriate, actual results could differ materially from those estimates considering the increased uncertainties surrounding the severity and duration of COVID-19. Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject to terms customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale.
Revenue Recognition	Revenue Recognition The Company recognizes revenue to depict the transfer of control to the Company’s customers in an amount reflecting the consideration the Company expects to be entitled to in exchange for performance obligations. In order to apply this revenue recognition principle, the Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when, or as, a performance obligation is satisfied. See Note 4, Revenue Recognition for further information. Revenues on point in time contracts are recognized when customer obtains control of the product, which is generally at the time of shipping. Revenues and costs on certain long-term contracts are recognized on the percentage-of-completion method measured on the basis of costs incurred to estimated total costs for each contract. This method is used because management considers it to be the best available measure of progress towards completion on these contracts. Revenues and costs on contracts are subject to changes in estimates throughout the duration of the contracts, and any required adjustments are made in the period in which a change in estimate becomes known. Unbilled receivables for net revenues recognized in excess of the amounts billed for active projects are recognized as contract assets on the balance sheet.
Cost Of Revenue	Goodwill Goodwill is measured as the excess of the cost of acquisition over the sum of the amounts assigned to identifiable tangible and intangible assets acquired less liabilities assumed. The Company performs an impairment assessment for goodwill at the reporting unit level on an annual basis as of the end of its October month end or more frequently if circumstances warrant. Its annual impairment assessment requires a comparison of the fair value of each of its reporting units to the respective carrying value. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying value of a reporting unit is greater than its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Additionally, the Company will consider the income tax effect from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. Determining the fair value of a reporting unit is subjective and requires the use of significant estimates and assumptions. With the assistance of an independent third-party appraisal firm, the Company estimates the fair value of its reporting units using an income approach based on the present value of future cash flows. It believes this approach yields the most appropriate evidence of fair value. The Company also utilizes the comparable company multiples method and market transaction fair value method to validate the fair value estimate using the income approach. The key assumptions utilized in its discounted cash flow model includes estimates of the rate of revenue growth and the discount rate based on a weighted average cost of capital. Any unfavorable material changes to these key assumptions could potentially impact its fair value determinations. For additional information, see Note 9, Goodwill and Other Intangible Assets. Cost of Revenues
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual cost. Cost is generally determined on the first-in, first-out (“FIFO”) basis. The Company typically analyzes its inventory aging and projected future usage on a quarterly basis to assess the adequacy of its inventory valuation reserve, which primarily consists of obsolescence and net realizable value estimates. These estimates are measured either on an item-by-item basis or higher-level inventory grouping and determined based on the difference between the cost of the inventory and estimated net realizable value. The provision for inventory valuation reserves is a component of the Company's cost of revenues. Assumptions about future demand are among the primary factors utilized to estimate net realizable value. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Only subsequent inventory transactions via sale or disposal would then release the established inventory reserve.
Business Acquisitions
Goodwill And Intangible Assets	Legal Contingencies The Company is currently involved in various legal claims and legal proceedings, some of which may involve substantial dollar amounts. Periodically, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, it accrues a liability for the estimated loss. The determination of probability and the determination as to whether exposure can be reasonably estimated requires management estimates. Because of uncertainties related to these matters, accruals are based on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to its pending claims and litigation and may revise its estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on its business, results of operations and financial position. For more information see Note 16, Contingencies, Commitments and Guarantees. Indefinite-Lived Intangible Assets
Impairment Of Other Long-Lived Assets	Other Long-Lived Assets In accordance with ASC Topic 360, Plant, Property, and Equipment, the Company performs impairment analyses of long-lived asset groups whenever events and circumstances indicate impairment. If indicators are present, it performs a recoverability test by comparing the sum of the undiscounted future cash flows specific to the asset group to its carrying value. If the recoverability test fails (sum of undiscounted cash flows are less than the asset group's carrying value), it then determines the fair value of the asset group and recognizes an impairment loss if the carrying value exceeds the estimated fair value.
Pension Benefits	Post-Retirement Benefits Pensions and other post-retirement benefit obligations and net periodic benefit costs are actuarially determined and are affected by several assumptions including the discount rate, mortality, and the expected long-term return on plan assets. Changes in assumptions and differences from actual results will affect the amounts of net periodic benefit cost recognized in future periods. These assumptions may also effect the amount and timing of future cash contributions. As required in the recognition and disclosure provisions of ASC Topic 715, Compensation - Retirement Benefits, the Company recognizes the over-funded or under-funded status of defined benefit post-retirement plans in its balance sheet, measured as the difference between the fair value of plan assets and the benefit obligations (the projected benefit obligation for pension plans and the accumulated post-retirement benefit obligation for other post-retirement plans). The change in the funded status is the net of the recognized net periodic benefit cost, cash contributions to the trust/benefits paid directly by the Company and recognized changes in other comprehensive income. Other comprehensive income changes are due to new actuarial gains and losses, new plan amendments and the amortizations of amounts in the net periodic benefit cost.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if the Company anticipates that it is more likely than not that it may not realize some or all of a deferred tax asset. In accordance with the provisions of ASC Topic 740, Income Taxes, the Company initially recognizes the financial statement effect of a tax position when, based solely on its technical merits, it is more likely than not (a likelihood of greater than fifty percent) that the position will be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard, are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statute of limitations. De-recognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained. If future results of operations exceed the Company's current expectations, its existing tax valuation allowances may be adjusted, resulting in future tax benefits. Alternatively, if future results of operations are less than expected, future assessments may result in a determination that some or all of the deferred tax assets are not realizable. Consequently, the Company may need to establish additional tax valuation allowances for a portion or all of the gross deferred tax assets, which may have a material adverse effect on its results of operations. Under ASC Topic 740, only the portion of the liability that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., due to the expiration of the statute of limitations) or are not expected to be paid within one year are classified as non-current. It is the Company’s policy to record estimated interest and penalties as income tax expense, and tax credits as a reduction in income tax expense. With respect to global intangible low-taxed income ("GILTI"), the Company has adopted a policy to account for this provision as a period cost. Also, the Company has adopted the impact of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2018-05 in its financial statements. For additional information, see Note 10, Income Taxes.
Share-Based Compensation	Share-Based Compensation Share-based compensation costs are based on the grant date fair value estimated in accordance with the provisions of ASC Topic 718, Accounting for Share Based Payments, and these costs are recognized over the requisite vesting period. The Black-Scholes option pricing model is used to estimate the fair value of each stock option at the date of grant. Black-Scholes utilizes assumptions related to volatility, the risk-free interest rate, the dividend yield and employee exercise behavior. Expected volatilities utilized in the model are based on the historic volatility of the Company’s stock price. The risk-free interest rate is derived from the U.S. Treasury Yield curve in effect at the time of the grant. The model incorporates exercise and post-vesting service termination assumptions based on an analysis of historical data. For additional information, see Note 13, Share-Based Compensation.
Environmental Compliance And Remediation	Environmental Compliance and Remediation
Foreign Currency Translation	Foreign Currency and Foreign Currency Contracts The Company's international subsidiaries operate and report their financial results using local functional currencies. Accordingly, all assets, liabilities, revenues, and costs of these subsidiaries are translated into United States ("U.S.") dollars using exchange rates in effect at the end of the relevant periods. The resulting translation adjustments are presented as a separate component of other comprehensive income. The Company does not provide for U.S. income taxes on foreign currency translation adjustments since it does not provide for such taxes on undistributed earnings of foreign subsidiaries. The Company is exposed to certain risks relating to its ongoing business operations including foreign currency exchange rate risk and interest rate risk. The Company currently uses derivative instruments to manage foreign currency risk on certain business transactions denominated in foreign currencies. To the extent the underlying transactions hedged are completed, these forward contracts do not subject us to significant risk from exchange rate movements because they offset gains and losses on the related foreign currency denominated transactions. These forward contracts do not qualify as hedging instruments and, therefore, do not qualify for fair value or cash flow hedge treatment. Any gains and losses on the Company's contracts are recognized as a component of other expense in its consolidated statements of (loss) income. The Company is subject to exchange rate related gains or losses resulting from foreign currency denominated transactions. Its net foreign exchange losses / (gains) recorded for the years ended December 31, 2020, 2019 and 2018 were $2.9 million, $(0.4) million, and $(1.7) million, respectively and are included in other (income) expense in the consolidated statements of (loss) income.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is calculated by dividing net income by the number of weighted average common shares outstanding. Diluted earnings per common share is calculated by dividing net income by the weighted average common shares outstanding and assumes the conversion of all dilutive securities when the effects of such conversion would not be anti-dilutive. Earnings per common share and the weighted average number of shares used to compute net earnings per common share, basic and assuming full dilution, are reconciled below (in thousands, except per share data): Year Ended December 31, 2020 2019 2018 Net Shares Per Share Net Shares Per Share Net Shares Per Share Basic EPS $ (185,498) 19,982 $ (9.28) $ (133,935) 19,903 $ (6.73) $ (39,384) 19,834 $ (1.99) Dilutive securities, principally common stock awards — — — — — — — — — Diluted EPS $ (185,498) 19,982 $ (9.28) $ (133,935) 19,903 $ (6.73) $ (39,384) 19,834 $ (1.99) Certain stock options to purchase common shares and restricted stock units ("RSUs") were anti-dilutive. There were 663,986 anti-dilutive stock options, RSUs, and RSU MSPs for the year ended December 31, 2020 with exercise prices ranging from $33.63 to $71.56. There were 431,165 anti-dilutive stock options and RSUs for the year ended December 31, 2019 with exercise prices ranging from $33.63 to $71.56. There were 1,041,454 anti-dilutive stock options and RSUs for the year ended December 31, 2018 with exercise prices ranging from $26.06 to $71.56.
Fair Value	Fair Value ASC Topic 820, Fair Value Measurement, defines fair value and includes a framework for measuring fair value and disclosing fair value measurements in financial statements. Fair value is a market-based measurement rather than an entity-specific measurement. The fair value hierarchy makes a distinction between assumptions developed based on market data obtained from independent sources (observable inputs) and the reporting entity’s own assumptions (unobservable inputs). This hierarchy prioritizes the inputs into three broad levels as follows: Level One : Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.
