Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of CIRCOR and its subsidiaries. The results of companies acquired during the year are included in the consolidated financial statements from the date of acquisition. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. These reclassifications have no effect on the previously reported net income. Use of Estimates The preparation of these financial statements in conformity with generally accepted accounting principles ("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 relate to acquisition accounting, estimated total costs for ongoing long-term contracts accounted for under the percentage of completion method, inventory valuation, share-based compensation, amortization and impairment of long-lived assets, pension benefits obligations, income taxes, 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. Revenue Recognition and Accounts Receivable Allowances Revenue is primarily recognized when title and risk of loss have passed to the customer, persuasive evidence of an arrangement exists, no significant post delivery obligations remain, the price to the buyers is fixed or determinable and collection of the resulting receivable is reasonably assured. Revenues and costs on certain long-term capital 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 change in estimate throughout the duration of the contracts, and any required adjustments are made in the period in which a change in estimate becomes known. Estimated losses on contracts in progress are recognized in the period in which a loss becomes known. Unbilled receivables for net revenues recognized in excess of the amounts billed for active projects are recognized within other current 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. We recognize 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. The Company makes estimates evaluating its allowance for doubtful accounts. The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon its historical experience 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. Cost of Revenue Cost of revenue primarily reflects the costs of manufacturing and preparing products for sale and, to a much lesser extent, the costs of performing services. Cost of revenue 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 the manufacturing plant. Additional expenses that directly result from the level of production activity at the manufacturing plant 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. Cost is generally determined on the first-in, first-out (“FIFO”) basis. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual cost. We typically analyze our inventory aging and projected future usage on a quarterly basis to assess the adequacy of our inventory allowance, which primarily consist of obsolescence and net realizable value estimates. These estimates are measured on an item-by-item basis determined based on the difference between the cost of the inventory and estimated market value. The provision for inventory allowance is a component of our cost of revenues. Assumptions about future demand are among the primary factors utilized to estimate market 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. Our inventory balance was $245 million as of December 31, 2017 , compared to $150 million as of December 31, 2016 . Our inventory allowances, which include amounts primarily for obsolescence and net realizable value estimates was $24 million as of December 31, 2017 , compared to $24 million as of December 31, 2016 . Our inventory balance as of December 31, 2017 includes a $8.5 million inventory fair value step up related to the Fluid Handling acquisition. If there were to be a sudden and significant decrease in demand for our products, significant price reductions, or if there were a higher incidence of inventory obsolescence for any reason, including a change in technology or customer requirements, we could be required to increase our inventory allowances and our gross profit could be adversely affected. Penalty Accruals Certain customer agreements, primarily in our long-cycle project related businesses and large aerospace programs, contain late shipment penalty clauses whereby we are contractually obligated to pay consideration to our customers if we do not meet specified shipment dates. The accrual for estimated penalties is shown as a reduction of revenue and is based on several factors including historical customer settlement experience and management’s assessment of specific shipment delay information. Accruals related to these potential late shipment penalties as of December 31, 2017 and 2016 were $2 million and $5 million , respectively. As we conclude performance under these agreements, the actual amount of consideration paid to our customers may vary from the amounts we currently have accrued. Business Acquisitions We account for business combinations under the acquisition method, and accordingly, the assets and liabilities of the acquired businesses are recorded at their estimated fair value on the acquisition date with the excess of the purchase price over their estimated fair value recorded as goodwill. We determine acquisition related asset and liability fair values through established valuation techniques for industrial manufacturing companies and utilize third party valuation firms to assist in the valuation of certain tangible and intangible assets. The consideration for our acquisitions may include future payments that are contingent upon the occurrence of a particular event. For acquisitions that qualify as business combinations, we record an obligation for such contingent payments at fair value on the acquisition date. We estimate the fair value of contingent consideration obligations through valuation models that incorporate probability adjusted assumptions related to the achievement of the milestones and thus likelihood of making related payments or by using a Monte Carlo simulation model. We revalue these contingent consideration obligations each reporting period. Changes in the fair value of our contingent consideration obligations are recognized within general and administrative expense in our consolidated statements of income. Accounting Standards Codification ("ASC") Topic 805, Business Combinations, provides guidance regarding business combinations and requires acquisition-date fair value measurement of identifiable assets acquired, liabilities assumed, and non-controlling interests in the acquiree. For additional information, refer to Note 3, Business Acquisitions. Legal Contingencies We are currently involved in various legal claims and legal proceedings, some of which may involve substantial dollar amounts. Periodically, we review the status of each significant matter and assess our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue a liability for the estimated loss. The determination of probability and the determination as to whether an 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, we reassess the potential liability related to our pending claims and litigation and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our business, results of operations and financial position. For more information related to our outstanding legal proceedings, see Note 14, Contingencies, Commitments and Guarantees. 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. For goodwill, we perform an impairment assessment at the reporting unit level on an annual basis as of the end of our October month end or more frequently if circumstances warrant. Our annual impairment assessment requires a comparison of the fair value of each of our 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, we 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, we estimate the fair value of our reporting units using an income approach based on the present value of future cash flows. We believe this approach yields the most appropriate evidence of fair value. We also utilize the comparable company multiples method and market transaction fair value method to validate the fair value amount we obtain using the income approach. The key assumptions utilized in our discounted cash flow model include our estimates of future cash flows from operating activities offset by estimated capital expenditures of the reporting unit, the estimated terminal value for each reporting unit, a discount rate based on a weighted average cost of capital, and overall economic conditions. Any unfavorable material changes to these key assumptions could potentially impact our fair value determinations. As such, we may experience fluctuations in revenues and operating results resulting in the non-achievement of our estimated growth rates, operating performance and working capital estimates utilized in our discounted cash flow models. For more information related to our Goodwill, see Note 7, Goodwill and Other Intangible Assets. Indefinite-Lived Intangible Assets For intangible assets with indefinite lives, we perform an impairment assessment at the asset level on an annual basis as of the end of our October month end or more frequently if circumstances warrant. Indefinite-lived intangible assets, such as trade names, are generally recorded and valued in connection with a business acquisition. These assets are reviewed at least annually for impairment, or more frequently if facts and circumstances warrant. We also utilized a fair value calculation to evaluate these intangibles. 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, we estimate the fair value using an income approach based on the present value of future cash flows. We note the fair value of each individual indefinite-lived asset exceeded the respective carrying amount, and no intangible impairments were recorded. For more information related to our Intangible Assets, see Note 7, Goodwill and Other Intangible Assets. Other Long-Lived Assets In accordance with ASC 360, Plant, Property, and Equipment, we perform impairment analyses of our long-lived assets, such as property, plant and equipment, whenever events and circumstances indicate that they may be impaired. When the undiscounted future cash flows are expected to be less than the carrying value of identified asset groupings being reviewed for impairment, the asset groupings are written down to fair value. See Note 6, Property, Plant and Equipment, for further information on impairment of other long-lived assets. Post Retirement Benefits Pensions and other post-retirement benefits 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 the assumptions and differences from actual results will affect the amounts of net periodic benefit cost recognized in future periods. These assumptions may also have an effect on 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 CIRCOR and recognized changes in other comprehensive income. Other comprehensive income changes are due to new actuarial gains and losses and 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 life of the employee group. Unrecognized actuarial gains and losses arise from several factors including experience and assumption changes in the benefit obligations and from 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 we anticipate that it is more likely than not that we 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 our current expectations, our 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, we 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 our 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. For more information related to our Income Taxes, see Note 8, 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 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 excluding the 2013 and 2014 CEO and CFO stock option awards which are valued using the Monte Carlo option pricing model as these are market condition awards. 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 forfeiture assumptions based on an analysis of historical data. Market condition stock option awards include both a service period and a market performance vesting condition. The stock options vest if certain stock price targets are met based on the stock price closing at or above the target for 60 consecutive trading days. Vested options may be exercised 25% at the time of vesting, 50% one year from the date of vesting and 100% two years from the date of vesting. These market condition stock option awards are being expensed utilizing a graded method and are subject to forfeiture in the event of employment termination (whether voluntary or involuntary) prior to vesting. To the extent that the market conditions above (stock price targets) are not met, those options will not vest and will forfeit 5 years from grant date. The Company used a Monte Carlo simulation option pricing model to value these option awards. See Note 11, Share-Based Compensation, for further information on 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 450, Contingencies, estimated costs are based upon current laws and regulations, existing technology and the most probable method of remediation. Foreign Currency Our 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 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. We do not provide for U.S. income taxes on foreign currency translation adjustments since we do not provide for such taxes on undistributed earnings of foreign subsidiaries. Our net foreign exchange losses / (gains) recorded for the years ended December 31, 2017 , 2016 and 2015 were $2.1 million , $2.1 million , and $0.8 million , respectively and are included in other (income) expense in the consolidated statements of income. See Note 16, Fair Value, for additional information on foreign currency exchange risk. Earnings Per Common Share Basic earnings per common share are 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, 2017 2016 2015 Net Income Shares Per Share Amount Net Income Shares Per Share Amount Net Income Shares Per Share Amount Basic EPS $ 11,789 16,674 $ 0.71 $ 10,101 16,418 $ 0.62 $ 9,863 16,850 $ 0.59 Dilutive securities, principally common stock options 175 (0.01 ) 118 (0.01 ) 63 (0.01 ) Diluted EPS $ 11,789 16,849 $ 0.70 $ 10,101 16,536 $ 0.61 $ 9,863 16,913 $ 0.58 Certain stock options to purchase common shares and restricted stock units ("RSUs") were anti-dilutive. There were 252,001 anti-dilutive stock options and RSUs for the year ended December 31, 2017 with exercise prices ranging from $51.84 to $71.56 . There were 36,281 anti-dilutive stock options and RSUs for the year ended December 31, 2016 with exercise prices ranging from $70.42 to $79.33 . There were 297,915 anti-dilutive stock options and RSUs for the year ended December 31, 2015 with exercise prices ranging from $41.17 to $79.33 . As of December 31, 2017 , there were 2,876 outstanding RSUs that contain rights to nonforfeitable dividend equivalents and are considered participating securities that are included in our computation of basic and fully diluted earnings per share. Cash and Cash Equivalents Our cash equivalents are invested in time deposits of financial institutions. We have 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. We currently have $64.5 million of cash which is owed back to Colfax as part of the acquisition. This amount is included within our cash and cash equivalents and other current liabilities within the consolidated balance sheet. Other Assets Other assets in the accompanying consolidated balance sheets include deferred debt issuance costs associated with our revolving credit facility, tax receivable 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 fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). We utilize fair value measurements for forward currency contracts, guarantee and indemnification obligations, certain pension plan assets, and certain intangible assets. Certain pension plan asset investments are measured at fair value using the net asset value per share (or its equivalent) practical expedient (the “NAV”). See Note 16, Fair Value, for additional information on fair value. Derivative Financial Instruments 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. GAAP requires all derivatives, whether designated in a hedging relationship or not, to be recorded on the balance sheet at fair value. Any unrealized gains and losses on our contracts are recognized as a component of other expense in our consolidated statements of income. See Note 16, Fair Value, for additional information on derivative financial instruments. 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, 3 to 10 years for manufacturing machinery and equipment, computer equipment and software, and furniture and fixtures. Motor vehicles are depreciated over a range of 2 to 6 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 revenue. Depreciation related to selling and administrative functions is reported in selling, general and administrative expenses. See Note 6, 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. Our research and development expenditures for the years ended December 31, 2017 , 2016 and 2015 were $5.5 million , $5.9 million and $5.9 million , respectively. New Accounting Standards Adopted In January 2017, the FASB issued ASU No. 2017-04, “Intangibles—Goodwill and Other (Topic 350)”. The ASU modifies the measurement of a goodwill impairment loss from the portion of the carrying amount of goodwill that exceeds its implied fair value to the excess of the carrying amount of a reporting unit that exceeds its fair value. This eliminates step 2 of the goodwill impairment test under current guidance. The ASU will be applied prospectively for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company early adopted this standard in connection with the 2017 goodwill impairment test. Not yet Adopted On May 10, 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. The amendments in this ASU also clarify that no new measurement date will be required if an award is not probable of vesting at the time a change is made and there is no change to the fair value, vesting conditions, and classification. The amendments in this ASU are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods. We intend to adopt the standard prospectively and have not yet determined its impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation—Retirement Benefits (Topic 715), which improves the consistency, transparency, and usefulness of the service cost and net benefit cost financial information components. The amendments in this ASU amend presentation requirements of service cost and other components of net benefit cost in the income statement. In addition, the ASU allows only the service cost component of net benefit cost to be eligible for capitalization. The amendments in this ASU are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods. We have not yet determined its impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. ASU 2017-01 provides further clarification of the definition of a business with the objective to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets versus businesses. The amendments in ASU 2017-01 provide criteria to determine when a set of assets and activities is not a business. ASU 2017-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The adoption of ASU 2017-01 is not expected to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-02, Leases. ASU 2016-02 outlines a model for lessees by recognizing all lease-related assets and liabilities on the balance sheet. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early application is permitted for all entities. ASU 2016-02 requires a modified retrospective approach for all leases existing at, or entered into after, the date of initial application, with an option to elect to use certain transition relief. We are still evaluating the requirements of ASU 2016-02 to determine the impact it will have on our consolidated financial statements but expect the standard to have a material impact on our assets and liabilities for the addition of right-o

Business Acquisitions

Business Acquisitions	12 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Business Acquisitions	Business Acquisitions Fluid Handling On September 24, 2017, CIRCOR entered into a Purchase Agreement (the “Purchase Agreement”) with Colfax Corporation (“Colfax”). Pursuant to the Purchase Agreement, on December 11, 2017, the Company acquired the fluid handling business of Colfax ("FH") for consideration consisting of $542.0 million in cash, 3,283,424 unregistered shares of the Company's common stock, with a fair value of approximately $143.8 million at closing, and the assumption of net pension and post-retirement liabilities of FH. The cash consideration is subject to customary working capital adjustments. The Company financed the cash consideration through a combination of committed debt financing and cash on hand. FH is a leader in the engineering, development‚ manufacturing‚ distribution‚ service and support of fluid handling systems. With a history dating back to 1860‚ FH is a leading supplier of screw pumps for high demand, severe service applications across a range of markets including general industry, commercial marine, defense, and oil & gas. FH leverages differentiated technology, and provides critical aftermarket customer support, to maintain leading positions in high demand niche markets. The operating results of FH have been included in our consolidated financial statements from the date of acquisition, reported within the Fluid Handling segment. Acquisition-related costs of $13.1 million , which primarily consisted of legal, financial advisory and acquisition transitional services, were expensed as corporate expenses during the year-ended December 31, 2017. The purchase price allocation is based upon a preliminary valuation of assets and liabilities that was prepared with assistance from a third party valuation specialist. The estimates and assumptions are subject to change as we obtain additional information during the measurement period (up to one year from the acquisition date). The purchase accounting is expected to be finalized in the third quarter of 2018. The assets and liabilities pending finalization include the valuation of acquired tangible and intangible assets, certain operating liabilities, and the evaluation of income taxes. Differences between the preliminary and final valuation could have a material impact on our future results of operations and financial position. The following table summarizes the preliminary fair value of the assets acquired and the liabilities assumed, at the date of acquisition: (in thousands) Cash and cash equivalents (a) $ 63,403 Restricted cash (a) 1,911 Accounts receivable 77,970 Inventory 79,329 Prepaid expenses and other current assets 16,937 Deferred income taxes 41,454 Property, plant and equipment 115,891 Identifiable intangible assets 388,000 Other assets 338 Accounts payable (46,045 ) Cash payable to seller (a) (65,314 ) Accrued and other expenses (63,115 ) Long-term post-retirement liabilities (143,067 ) Other long-term liabilities (11,215 ) Deferred tax liabilities (45,933 ) Total identifiable net assets $ 410,544 Goodwill 293,344 Total purchase price $ 703,888 Consideration Base purchase price 542,000 Net working capital and other purchase accounting adjustments 18,121 Common Stock 143,767 Total $ 703,888 (a) cash acquired to be returned to seller. The fair value of accounts receivable acquired approximates the contractual value of $78.0 million . The excess of purchase price paid over the fair value of FH's net assets was recorded to goodwill, which is primarily attributable to projected future profitable growth, market penetration, as well as an expanded customer base for the Fluid Handling segment. Approximately 50% of goodwill is projected to be deductible for income tax purposes. The FH acquisition resulted in the preliminary identification of the following identifiable intangible assets: Intangible assets acquired (in thousands) Weighted average amortization period (in years) Customer relationships $ 215,000 22 Existing technologies 107,000 20 Trade names 44,000 Indefinite-life Backlog 22,000 4 Total intangible assets $ 388,000 The fair value of the intangible assets was based on variations of the income approach, which estimates fair value based on the present value of cash flows that the assets are expected to generate. These approaches included the relief-from-royalty method and multi-period excess earnings method, depending on the intangible asset being valued. Customer relationships, aftermarket backlog, and existing technology are amortized on a cash flow basis which reflects the economic benefit consumed. The trade name was assigned an indefinite life based on the Company’s intention to keep the trade names for an indefinite period of time. Refer to Note 7, Goodwill and Other Intangible Assets, for future expected amortization to be recorded. The results of operations of FH have been included in our consolidated financial statements beginning on the acquisition date and reported within the Fluid Handling segment. The results for the year ended December 31, 2017 include $36.5 million of net revenue and a $1.1 million operating loss. The following unaudited pro forma information presents the combined results of operations as if the acquisition had been completed on January 1, 2016, the beginning of the comparable prior annual reporting period. The unaudited pro forma results include: (i) amortization associated with preliminary estimates for the acquired intangible assets; (ii) interest expense on borrowings in connection with the acquisition; (iii) the associated tax impact on these unaudited pro forma adjustments; and the transaction costs presented in the earliest period (2016). The unaudited pro forma results do not reflect any cost saving synergies from operating efficiencies or the effect of the incremental costs incurred in integrating the two companies. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of the period presented, nor are they indicative of future results of operations (in thousands): (Unaudited) Year ended December 31, Year ended December 31, 2017 2016 Net Revenues $ 1,098,978 $ 1,052,277 Net Income $ (6,475 ) $ (51,288 ) CFS Acquisition On October 12, 2016, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Downstream Holding, LLC, a Delaware limited liability company which does business as Critical Flow Solutions (“Downstream” or “CFS”), Downstream Acquisition LLC, a Delaware limited liability company and subsidiary of the Company, and Sun Downstream, LP, a Delaware limited partnership, to acquire all of the outstanding units of Downstream. The consideration payable by the Company pursuant to the terms of the Merger Agreement was $195.0 million , subject to (i) up to an additional $15.0 million payable pursuant to an earn-out relating to achievement of a specified order bookings target by the acquired business in the twelve month period ending September 30, 2017, (ii) increase or decrease based on deviation, subject to certain limitations, from a working capital target, (iii) decrease for indebtedness and certain transaction expenses of CFS, (iv) increase for the amount of CFS cash as of the closing, and (v) a potential increase for certain transaction related tax benefits, net of certain adjustments, if and when realized by the Company. The total consideration paid at closing on October 13, 2016 was approximately $198.0 million in cash, net of cash acquired and including amounts paid at closing for estimated adjustments for CFS working capital, the repayment of CFS outstanding indebtedness and payment of certain transaction expenses. The Company funded the purchase price and payments at closing from borrowings under the Company’s existing credit agreement. The estimated fair value of the earn-out, using the Monte Carlo simulation model, was $12.2 million as of the acquisition date and December 31, 2016. The Monte Carlo model calculates the probability of satisfying the target conditions stipulated in the earn-out. Based on actual performance through the earn-out period ending September 30, 2017, the specified order bookings target in the specified timeframe was not achieved, as project bookings shifted out to the future. Accordingly, the actual achievement resulted in an earn-out of zero as of October 1, 2017. The fair value of the earn-out decreased $12.2 million during the year ended December 31, 2017 and was recorded within Special and restructuring charges (recoveries), net as a gain. The Company received $1.5 million as settlement for working capital adjustments during 2017. This reduction of purchase price was recorded as a reduction of goodwill. The operating results of CFS have been included in our consolidated financial statements from the date of acquisition and reported within the Energy segment. The purchase price allocation is based upon a valuation of assets and liabilities that was prepared with assistance from a third party valuation specialist. The assets and liabilities include the valuation of acquired intangible assets, certain operating liabilities, and the evaluation of deferred income taxes. The purchase accounting was finalized during the third quarter of 2017. The following table summarizes the fair value of the assets acquired and the liabilities assumed, at the date of acquisition: (in thousands) Cash and cash equivalents $ 6,603 Accounts receivable 28,128 Unbilled receivable 10,786 Inventory 18,701 Prepaid and other current assets 5,671 Property, plant and equipment 21,214 Identifiable intangible assets 101,600 Accounts payable (11,655 ) Accrued and other expenses (8,866 ) Deferred revenue (3,997 ) Deferred income taxes (40,645 ) Long term income tax payable (556 ) Total identifiable net assets $ 126,984 Goodwill 89,473 Total purchase price $ 216,457 The fair value of accounts receivable acquired approximates the contractual value of $28.1 million . The excess of purchase price paid over the fair value of CFS' net assets was recorded to goodwill, which is primarily attributable to projected future profitable growth, market penetration, as well as an expanded customer base for the Energy segment. Goodwill is not deductible for income tax purposes. The CFS acquisition resulted in the identification of the following identifiable intangible assets: Intangible assets acquired (in thousands) Weighted average amortization period (in years) Customer relationships $ 49,600 14 Existing technologies 25,800 10 Trade names 24,100 Indefinite Backlog 2,100 1 Total intangible assets $ 101,600 The fair value of the intangible assets was based on variations of the income approach, which estimates fair value based on the present value of cash flows that the assets are expected to generate. These approaches included the relief-from-royalty method, incremental cash flow method, multi-period excess earnings method and direct cash flow method, depending on the intangible asset being valued. Customer relationships, aftermarket backlog, and existing technology are amortized on a cash flow basis which reflects the economic benefit consumed. The trade name was assigned an indefinite life based on the Company’s intention to keep the DeltaValve and TapcoEnpro names for an indefinite period of time. Refer to Note 7, Goodwill and Other Intangible Assets, for future expected amortization to be recorded.

The expense for income taxes differed from the U.S. statutory rate due to the following: Year Ended December 31, 2017 2016 2015 Expected federal income tax rate 35.0 % 35.0 % 35.0 % State income taxes, net of federal tax benefit 0.3 (4.8 ) (0.7 ) Change in state tax rate — — 3.5 Change in valuation allowance on state net operating losses — 18.9 (7.3 ) Foreign tax rate differential (38.9 ) (38.4 ) (18.9 ) Unbenefited foreign losses 2.9 14.7 41.4 Foreign tax credits — (26.6 ) — Manufacturing deduction (2.8 ) — (1.6 ) Research and development credit (8.4 ) (6.6 ) (1.1 ) Foreign audit settlement — — 6.0 Transaction costs 8.5 3.1 (0.5 ) Release of contingent consideration (69.9 ) — — Provisional Impact of Tax Cuts and Jobs Act (8.2 ) — — Change in tax reserves (16.3 ) (0.5 ) 0.7 Other, net 4.9 0.8 (0.5 ) Effective tax rate (92.9 )% (4.4 )% 56.0 % As of December 31, 2017 and 2016 , the Company maintained a total valuation allowance of $22.1 million and $3.0 million , respectively, which relates to foreign and state deferred tax assets as of December 31, 2017 and December 31, 2016. The valuation allowance is based on estimates of taxable income in each of the jurisdictions in which we operate and the period over which our deferred tax assets will be recoverable. The increase in the valuation allowance is primarily due to the preliminary valuation allowance on certain deferred tax assets in relation to the FH acquisition. The following table provides a summary of the changes in the deferred tax valuation allowance for the years ended December 31, 2017 , 2016 , and 2015 (in thousands): December 31, 2017 2016 2015 Deferred tax valuation allowance at January 1 $ 3,028 $ 892 $ 9,448 Additions 712 2,257 15 Acquired 18,494 — — Deductions (167 ) (121 ) (7,798 ) Translation adjustments — — (773 ) Deferred tax valuation allowance at December 31 $ 22,067 $ 3,028 $ 892 As we closed the Brazil site in 2016, we do not believe that any of the deferred tax assets related to Brazil have any value. Accordingly, this portion of the valuation allowance was written off during 2015, along with the related deferred tax assets. On December 18, 2015, legislation was enacted that permanently extended the U.S. research and development ("R&D") tax credit. Accordingly, the Company recorded the entire benefit of $0.3 million for the R&D tax credit attributable to 2015 in the fourth quarter. 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 2014 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. During 2015, the Company settled a tax audit in Italy for $2.2 million , of which $0.9 million had been accrued in 2014. During 2015, the Company restructured its multi-state activities, which resulted in a reduction of its state tax rate. In connection with this reduction, the Company recorded a one time tax expense of $0.8 million to reflect the effect of this tax rate reduction on its deferred tax assets. In addition, the Company recognized a tax benefit of $1.6 million on certain state net operating loss carryforwards, as it is more likely than not to utilize these losses within the carryforward period. As of December 31, 2017 , the Company had foreign tax credits of $16.4 million , foreign net operating losses of $45.6 million , state net operating losses of $56.3 million and state tax credits of $2.2 million . As of December 31, 2016 , the Company had foreign tax credits of $17.7 million , foreign net operating losses of $1.5 million , state net operating losses of $57.2 million and state tax credits of $2.0 million . The foreign tax credits, if not utilized, will expire in 2026 . A portion of the foreign net operating losses ($20.2 million) expire at various dates through 2029; the remainder have an unlimited carryforward period. The state net operating losses and state tax credits, if not utilized, will expire at various dates through 2037 . The Company repatriated $32 million of foreign earnings to the U.S. during the fourth quarter of 2016, resulting in a tax benefit of $2.6 million in the year ended December 31, 2016. The tax benefit is a result of foreign tax credits associated with the repatriation, in excess of the U.S. corporate tax rate. During 2016, the Company recorded a valuation allowance and additional tax expense of $1.8 million on certain state net operating loss carryforwards, due to the uncertainty of the Company's ability to utilize these losses within the foreseeable future. The amount of net operating losses considered realizable, however, could be adjusted if objective evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as the Company’s projections for growth. On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act includes significant changes to the U.S. corporate income tax system including: a federal corporate rate reduction from 35% to 21% ; limitations on the deductibility of interest expense and executive compensation; creation of the base erosion anti-abuse tax (“BEAT”), a new minimum tax; and the transition of U.S. international taxation from a worldwide tax system to a modified territorial tax system. The change to a modified territorial tax system resulted in a one-time U.S. tax liability on those earnings which have not previously been repatriated to the U.S. (the “Transition Tax”), with future distributions not subject to U.S. federal income tax when repatriated. A majority of the provisions in the Tax Act are effective January 1, 2018. In response to the Tax Act, the SEC staff issued guidance on accounting for the tax effects of the Tax Act. The guidance provides a one-year measurement period for companies to complete the accounting. We reflected the income tax effects of those aspects of the Tax Act for which the accounting is complete. To the extent our accounting for certain income tax effects of the Tax Act is incomplete but we are able to determine a reasonable estimate, we recorded a provisional estimate in the financial statements. For items that we cannot determine a provisional estimate to be included in the financial statements, we continued to apply the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. As the analysis is completed, the ultimate impact may differ from these provisional amounts. In connection with our initial analysis of the impact of the Tax Act, we have recorded a provisional estimate of $0.5 million net tax benefit for the period ended December 31, 2017. This benefit consists of provisional estimates of zero net expense for the Transition Tax liability, and $0.5 million benefit from the remeasurement of our deferred tax assets/liabilities due to the corporate rate reduction. On a provisional basis, the Company does not expect to owe the one-time Transition Tax liability, based on foreign tax pools that are in excess of U.S. tax rates. We are in process of determining the impact of the Tax Act on our U.S. foreign tax credit carryforwards (deferred tax asset), and are unable to record a provisional estimate at this time. Any adjustment, when determined, could have an adverse impact to our net deferred tax asset. We have not completed our accounting for the income tax effects of certain elements of the Tax Act. The Tax Act creates a new requirement that certain income, such as Global Intangible Low-Taxed Income (“GILTI”), earned by a controlled foreign corporation must be included in the gross income of its U.S. shareholder. Because of the complexity of the new GILTI and BEAT tax rules, we are continuing to evaluate the impact of these provisions and whether taxes due on future U.S. inclusions related to GILTI or BEAT should be recorded as a current period expense when incurred, or factored into the measurement of deferred taxes. As a result, we have not included an estimate of the tax expense or benefit related to these items for the period ended December 31, 2017. As of December 31, 2017 , the liability for uncertain income tax positions was approximately $3.0 million . Approximately $2.6 million as of December 31, 2017 represents the amount that if recognized would affect the Company’s effective income tax rate in future periods. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, or if the applicable statute of limitations lapses. The impact of the amount of such changes to previously recorded uncertain tax positions could range from zero to $1.5 million. The impact of the lapse of statute of limitations below primarily represents the change in tax reserves disclosed in the reconciliation of the effective tax rate. The table below does not include interest and penalties of $0.4 million and $0.2 million as of December 31, 2017 and 2016 , respectively. The following is a reconciliation of the Company’s liability for uncertain income tax positions for the years ended December 31, 2017 and 2016 (in thousands). December 31, 2017 2016 2015 Balance beginning January 1 $ 3,000 $ 2,937 $ 1,978 Additions/(reductions) for tax positions of prior years (7 ) (102 ) 521 Additions/(reductions) based on tax positions related to current year (65 ) 483 69 Acquired uncertain tax position balance 1,221 1,326 Settlements (338 ) — (544 ) Lapse of statute of limitations (978 ) (328 ) (612 ) Currency movement 181 10 199 Balance ending December 31 $ 3,014 $ 3,000 $ 2,937 Undistributed earnings of our foreign subsidiaries amounted to $221.3 million at December 31, 2017 and $222.6 million at December 31, 2016 . The undistributed earnings of our foreign subsidiaries are considered to be indefinitely reinvested and accordingly, no provision for U.S. federal and state income taxes has been recorded. 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.

The New 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 we had borrowings of $273.5 million outstanding, was terminated on December 11, 2017 and replaced by the New Credit Agreement. The new term loan requires quarterly principal payments of 0.25% of initial aggregate principal amount beginning March 29, 2018 with the balance due at maturity. The Company has mandatory debt repayment obligations of $7.9 million per year ( $2.0 million per quarter) until 2024 under the New Credit Agreement. Additional loans of up to $150.0 million (plus the amount of certain voluntary prepayments) and an unlimited amount subject to compliance with a first lien net leverage ratio of 4.50 to 1.00 may be made available under the New Credit Agreement upon request of the Company subject to specified terms and conditions. The Company may repay any borrowings under the New Credit Agreement at any time, subject to certain limited and customary restrictions stated in the New 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 were recorded as other assets. In connection with the Prior Credit Agreement, a portion of the term debt was extinguished and $0.2 million of deferred financing costs was written off as a debt extinguishment (included in special charges on the consolidated statements of income) and a portion was tested as a modification ($0.1 million) and rolled into the new debt discount. In connection with the Prior Credit Agreement revolving facility, $1.6 million of deferred financing fees was written off as debt extinguishment and $0.6 million was rolled into the New Credit Agreement (included in other assets) based on the borrowing capacity of the underlying banks. As of December 31, 2017, we had borrowings of $818.9 million outstanding under the New Credit Agreement and $30.0 million in letters of credit issued under the New Credit Agreement. The Company recorded non-cash interest expense of $0.8 million , $0.4 million , and $0.4 million for December 31, 2017, 2016, and 2015 related to the amortization of its deferred financing costs described above. The New Credit Agreement revolving line of credit facility matures on December 11, 2022 whereas the term loan facility matures on December 11, 2024. The outstanding principal amounts bear interest at a fluctuating rate (generally the 30 day LIBOR rate) per annum plus an applicable margin of 3.50% with respect to LIBOR loans and 2.50% with respect to base rate loans. As of December 31, 2017 and December 31, 2016, the outstanding balance of the Company’s debt approximated its fair value based on current rates available to the Company for debt of the same maturity and is a Level 2 financial instrument.

Share-Based Compensation

Share-Based Compensation	12 Months Ended
	Dec. 31, 2017
Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation We have two share-based compensation plans as of December 31, 2017 : (1) the 2014 Stock Option and Incentive Plan (the "2014 Plan") and (2) the Amended and Restated 1999 Stock Option and Incentive Plan (the "1999 Plan"). The 2014 Plan was adopted by our Board of Directors on February 12, 2014 and approved by our shareholders at the Company's annual meeting held on April 30, 2014. As of April 30, 2014, no new awards will be granted under the 1999 Plan. As a result, any shares subject to outstanding awards under 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 2014 Plan. Both plans permit the grant of the following types of awards to our officers, other employees and non-employee directors: incentive stock options; nonqualified stock options; deferred stock awards; restricted stock awards; unrestricted stock awards; performance share awards; cash-based awards; stock appreciation rights ("SARs") and dividend equivalent rights. The 2014 Plan provides for the issuance of up to 1,700,000 shares of common stock (subject to adjustment for stock splits and similar events). Under the 2014 Plan, shares issued for awards other than stock options or SARs count against the aggregate share limit as 1.9 shares for every share actually issued. New stock options granted under the 2014 Plan could have varying vesting provisions and exercise periods. All stock options and RSUs granted under the 1999 Plan are either 100% vested or have been terminated. RSUs granted under the 2014 Plan generally vest within three years. RSUs will be settled in shares of our common stock. As of December 31, 2017 , there were 710,326 shares available for grant under the 2014 Plan. As of December 31, 2017 , there were 848,427 stock options (including the CEO and CFO stock option awards noted below) and 259,357 RSUs outstanding. As of December 31, 2017 , there were 2,876 outstanding RSUs that contain rights to nonforfeitable dividend equivalents and are considered participating securities that are included in our computation of basic and fully diluted earnings per share. There is no difference in the earnings per share amounts between the two class method and the treasury stock method, which is why we continue to use the treasury stock method. During the year ended December 31, 2017 , we granted 142,428 stock option awards compared with 210,633 in 2016 and 118,992 in 2015 . On April 9, 2013, we granted stock options to purchase 200,000 shares of common stock to our newly appointed President and Chief Executive Officer at an exercise price of $41.17 per share ("2013 CEO Option Award"). On December 2, 2013, we granted stock options to purchase 100,000 shares of common stock to our newly appointed Executive Vice President and Chief Financial Officer at an exercise price of $79.33 per share ("2013 CFO Option Award"). On March 5, 2014, we granted stock options to purchase 100,000 shares of common stock to our President and Chief Executive Officer at an exercise price of $70.42 per share ("2014 CEO Option Award"). The 2013 CEO Option Award, the 2013 CFO Option Award, and the 2014 CEO Award were considered inducement awards and were granted outside of the Company's 1999 Plan. All three of these option awards include a service period and a market performance vesting condition. The stock options will vest if the following stock price targets are met based on the stock price closing at or above these targets for 60 consecutive trading days: 2013 CEO Option Award: Stock Price Target Cumulative Vested Portion of Stock Options (in Shares) $50.00 50,000 $60.00 100,000 $70.00 150,000 $80.00 200,000 2013 CFO and 2014 CEO Option Awards: Stock Price Target Cumulative Vested Portion of Stock Options (in Shares) $87.50 25,000 $100.00 50,000 $112.50 75,000 $125.00 100,000 As the CEO Option Awards and the CFO Option Award vest, they may be exercised 25% at the time of vesting, 50% one year from the date of vesting and 100% two years from the date of vesting. On August 8, 2013, the $50.00 Stock Price Target for the 2013 CEO Option Award was achieved. On January 6, 2014 and January 28, 2014, the $60.00 and $70.00 Price targets for the 2013 CEO Option Award were achieved, respectively. Therefore, 150,000 options have vested and are exercisable under the 2013 CEO Option Award. As of December 31, 2017 , none of the options awarded in connection with the 2013 CFO Option Award or the 2014 CEO Option Award have vested. These stock option awards are being expensed utilizing a graded method and are subject to forfeiture in the event of employment termination (whether voluntary or involuntary) prior to vesting. All three of these option awards have a 10 year term but to the extent that the market conditions above (Stock Price Targets) are not met within 5 years, these options will not vest and will forfeit 5 years from grant date. The Company used a Monte Carlo simulation option pricing model to value these option awards. The average fair value of stock options granted during the year ended December 31, 2017, 2016, and 2015 of $19.36 , $17.88 , and $26.32 , respectively, was estimated using the following weighted-average assumptions: Year Ended December 31, 2017 2016 2015 Risk-free interest rate 1.7 % 1.2 % 1.4 % Expected life (years) 4.5 4.5 4.5 Expected stock volatility 35.1 % 36.2 % 40.4 % Expected dividend yield 0.2 % 0.4 % 0.3 % We account for Restricted Stock Unit Awards (“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, 2017 and December 31, 2016 we granted 90,725 and 98,942 RSU Awards with approximate fair values of $ 55.28 and $ 41.09 per RSU Award, respectively. During 2017 and 2016 , the Company granted performance-based RSUs as part of the overall mix of RSU Awards. These performance-based RSUs include metrics for achieving Return on Invested Capital and Adjusted Operating Margin with target payouts ranging from 0% to 200% . Of the 90,725 RSUs granted during 2017 , 31,369 are performance-based RSU awards. This compares to 51,026 performance-based RSU awards granted in 2016 . The CIRCOR Management Stock Purchase Plan, which is a component of both the 2014 Plan and the 1999 Plan, 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”). In addition, non-employee directors may elect to receive RSUs in lieu of all or a portion of their annual directors’ retainer fees. Each RSU MSP represents a right to receive one share of our 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. RSU MSPs totaling 26,726 and 20,130 with per unit discount amounts representing fair values of $ 20.13 and $ 12.83 were granted under the CIRCOR Management Stock Purchase Plan during the years ended December 31, 2017 and December 31, 2016 , respectively. Compensation expense related to our share-based plans for the year ended December 31, 2017 , 2016 , and 2015 was $3.8 million , $5.5 million , and $6.5 million respectively. Share-based compensation expense is recorded as selling, general, and administrative expense. As of December 31, 2017 , there was $7.8 million of total unrecognized compensation costs related to our outstanding share-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 2.1 years. This compares to $6.8 million for 2016 and $7.0 million for 2015 , respectively. The increase in total unrecognized compensation costs from 2017 and 2016 primarily relates to equity awards granted to participants from our newly acquired Fluid Handling reporting segment. A summary of the status of all stock options granted to employees and non-employee directors as of December 31, 2017 , 2016 , and 2015 and changes during the years are presented in the table below: December 31, 2017 2016 2015 Options Weighted Average Exercise Price Options Weighted Average Exercise Price Options Weighted Average Exercise Price Options outstanding at beginning of period 736,319 $ 52.30 570,737 $ 56.86 486,004 $ 57.85 Granted 142,428 60.99 210,633 38.89 118,992 51.84 Exercised (17,708 ) 39.91 (5,982 ) 41.05 (7,717 ) 33.44 Forfeited (10,136 ) 51.99 (33,014 ) 45.25 (26,542 ) 59.25 Expired (2,476 ) 61.38 (6,055 ) 65.34 — — Options outstanding at end of period 848,427 $ 53.99 736,319 $ 52.30 570,737 $ 56.86 Options exercisable at end of period 309,824 $ 45.66 226,386 $ 45.20 140,248 $ 43.08 The weighted average contractual term for stock options outstanding and exercisable as of December 31, 2017 was 5.3 years and 4.6 years, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2017 , 2016 and 2015 was $ 0.4 million , $ 0.1 million and $ 0.1 million , respectively. The aggregate fair value of stock-options vested during the years ended December 31, 2017 , 2016 and 2015 was $ 1.6 million , $ 1.7 million and $ 1.2 million , respectively.

Risks and Uncertainties [Abstract]
Concentrations Of Risk	Concentrations of Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. A significant portion of our revenue and receivables are from customers who are either in or service the energy, aerospace, defense and industrial markets. We perform ongoing credit evaluations of our customers and maintain allowances for potential credit losses. For the years ended December 31, 2017, 2016 and 2015 , we had no customers from which we derive revenues that exceed the threshold of 10% of the Company’s consolidated revenues.

General Discussion of Pension and Other Postretirement Benefits [Abstract]
Employee Benefit Plans	US Contribution Plan We offer 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 our 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, we match a specified percentage of employee contributions, and are able to make a discretionary core contribution, subject to certain limitations. During 2017, we contributed 50% of the amount contributed by the employee, up to a maximum of 5% of the employee’s earnings. Our matching contributions vest at a rate of 20% per year of service, with full vesting after 5 years of service. The cost of our 401K plan is outlined below: Year Ended December 31, 2017 2016 2015 Cost of 401(k) plan $ 1,978 $ 1,509 $ 2,886 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. On December 11, 2017, the Company acquired FH. The acquisition included all of the pension obligations outside of the U.S., and a significant portion of the post-retirement obligations in the U.S. In connection with the acquisition, all post-retirement obligations were measured at December 11, 2017. In the U.S., 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. Our plans and FH plans 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 as a result of the 2017 acquisition of the FH business. The obligations are primarily attributed to partially funded plans in Germany and the U.K. During fiscal year 2017, we made $0.8 million in cash contributions to our qualified defined benefit pension plan, in addition to $0.4 million in payments for our nonqualified plan. In 2018, we expect to make defined benefit plan contributions based on the minimum required funding in accordance with statutory requirements (approximately $0 in the U.S. and approximately $6.0 million for our 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. We anticipate fulfilling these commitments through our generation of cash flow from operations. The U.S. pension obligations acquired in the acquisition are a carve-out from a prior plan, and a portion of the plan assets are expected to transfer to the existing CIRCOR plan in April, 2018. U.S. pension investments related to the carve-out are managed by Colfax Corporation as the Plan Administrator of the prior plan during the period from December 11, 2017 through the time that plan assets are transferred. We have recorded a receivable of $178.9 million ( $2.3 million included in return on assets) related to this asset transfer, which has been netted against the pension obligation in the pension liability on the balance sheet. The components of net periodic benefit cost for the postretirement plans were as follows (in thousands): Pension Benefits Other Post-retirement Benefits (1) Year Ended December 31, Year Ended December 31, 2017 2016 2015 2017 Components of net periodic benefit cost: Service cost $ 181 $ — $ — $ — Interest cost $ 2,158 $ 2,185 $ 2,193 $ 20 Expected return on assets (2,994 ) (2,562 ) (2,655 ) — Amortization — Net periodic benefit cost (655 ) (377 ) (462 ) 20 Net loss amortization 735 893 843 — Prior service cost amortization — — — — Total amortization 735 893 843 — Pension settlement charge — 4,457 — — Net periodic benefit cost $ 80 $ 4,973 $ 381 $ 20 Net periodic benefit cost $ 80 $ 9,430 $ 381 $ 20 (1) No Other Post-retirement Benefits in 2016 & 2015. 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, 2017 2016 2015 2017 Net periodic benefit cost (1): Discount rate – U.S. 3.86% 4.11% 3.82% 3.63% Expected return on plan assets - U.S. (2) 7.25% 6.75% 7.25% N/A Rate of compensation increase - U.S. N/A NA N/A N/A Benefit obligations: N/A Discount rate – U.S. 3.27% 3.86% 4.11% 3.48% Discount rate – Foreign 1.97% N/A N/A N/A Rate of compensation increase - U.S. N/A — — N/A Rate of compensation increase - Foreign 3.11% N/A N/A N/A (1) Assumption shown excludes those that would have been applicable for 21 days of CIRCOR's ownership of FH. (2) Excludes estimate of return on assets still held in the prior plan which had an expected long-term return on plan assets for the time since acquisition of 6.25% for 2017 for which CIRCOR is entitled to their portion of the return. 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 the acquisition of FH on December 11, 2017, the Company has changed the method used to estimate the service and interest cost components of the net periodic benefit costs. 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. This approach was only used for the period between December 11, 2017 and December 31, 2017 for the FH plans in the U.S., UK, and Germany. 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. The Company will account for this change prospectively for the legacy CIRCOR plans as a change in estimate beginning in the first quarter of 2018. Prior to this date, the service and interest costs were determined using a single weighted-average discount rate based on the AA yield curves used to measure the benefit obligation at the measurement date. Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plan. A one-percentage point change in assumed health care cost trend rates would have the following pre-tax effects: 1 % Increase 1% Decrease Effect on total service and interest cost components for the year ended December 31, 2017 — — Effect on post-retirement benefit obligation at December 31, 2017 $ 1,639 $ (1,308 ) In selecting the expected long-term return on assets for the qualified and foreign plans, we considered the average rate of earnings expected on the funds invested or to be invested to provide for the benefits of these plans. We, 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. During the third quarter of 2016, management offered a lump sum cash payout option to terminated and vested participants in the U.S. Plan. In connection with this action, the participants who opt to avail themselves of this program closed during the fourth quarter 2016. During the fourth quarter of 2016, we incurred a $4.5 million pension settlement charge which has been recorded within the Special and restructuring charges, net line item. The funded status of the defined benefit post-retirement plans and amounts recognized in the consolidated balance sheets, measured as of December 31, 2017 and December 31, 2016 were as follows (in thousands): Pension Benefits Other Post-retirement Benefits December 31, December 31, 2017 2016 2017 2016 Change in projected benefit obligation: Balance at beginning of year $ 45,300 $ 56,939 $ — $ — Service cost 181 — — Interest cost 2,158 2,185 20 — Actuarial loss (gain) 413 (2,932 ) 263 — Exchange rate (gain) / loss 5,759 — — — Acquisitions 348,542 — 11,445 — Benefits paid (2,715 ) (2,092 ) (43 ) — Settlement payments — (8,800 ) — — Balance at end of year $ 399,638 $ 45,300 $ 11,685 $ — Change in fair value of plan assets: Balance at beginning of year $ 31,776 $ 39,369 $ — $ — Actual return on assets (1) 10,374 1,904 — — Exchange rate (gain) / loss 1,256 — — Acquisitions - Transferred 28,903 — — Acquisitions - Plan receivable from Colfax 176,572 — — — Benefits paid (2,715 ) (2,092 ) (43 ) — Settlement payments — (8,800 ) — — Employer contributions 1,417 1,395 43 — Fair value of plan assets at end of year (2) $ 247,583 $ 31,776 $ — $ — Funded status: Excess of benefit obligation over the fair value of plan assets $ (152,055 ) $ (13,524 ) $ (11,685 ) $ — Pension plan accumulated benefit obligation (“ABO”) $ 399,638 $ 45,300 N/A N/A (1) Includes $2.3 million of plan assets still held in the prior plan at Colfax.

Commitments and Contingencies Disclosure [Abstract]
Contingencies, Commitments And Guarantees	Contingencies, Commitments and Guarantees Legal Proceedings We are subject to various legal proceedings and claims pertaining to matters such as product liability or contract disputes, including issues that may arise under certain customer contracts with aerospace and defense customers. We are also subject to other proceedings and governmental inquiries, inspections, audits or investigations pertaining to issues such as tax matters, patents and trademarks, pricing, business practices, governmental regulations, employment and other matters. Although the results of litigation and claims cannot be predicted with certainty, we believe 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 our business, financial condition, results of operations or liquidity. Asbestos-related product liability claims continue to be filed against two of our subsidiaries: Spence Engineering Company, Inc. (“Spence”), the stock of which we acquired in 1984; and CIRCOR Instrumentation Technologies, Inc. (f/k/a Hoke Incorporated) (“Hoke”), the stock of which we acquired in 1998. Due to the nature of the products supplied by these entities, the markets they serve and our historical experience in resolving these claims, we do not believe that these asbestos-related claims will have a material adverse effect on the financial condition, results of operations or liquidity of Spence or Hoke, or the financial condition, consolidated results of operations or liquidity of the Company. On February 21, 2018, the Company entered into a mediated settlement regarding a wage and hour action in California by a former employee. In October 2016, the plaintiff alleged non-compliance with California State labor law, including missed or late meal breaks, for hourly employees of CIRCOR Aerospace, Inc. in Corona, California. The total settlement amount of $2.4 million has been recorded as a liability at December 31, 2017. This settlement resolves all wage/hour claims by all potentially affected employees through the settlement date and is expected to be approved by the California Superior Court within the next six to twelve months. Standby Letters of Credit We execute standby letters of credit, which include bank guarantees, bid bonds and performance bonds, in the normal course of business to ensure our performance or payments to third parties. The aggregate notional value of these instruments was $77.7 million at December 31, 2017 of which $30.0 million were syndicated under our New Credit Agreement. Our historical experience with these types of instruments has been good and no claims have been paid in the current or past several fiscal years. We believe 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, 2017 . The following table contains information related to standby letters of credit instruments outstanding as of December 31, 2017 (in thousands): Term Remaining Maximum Potential Future Payments 0–12 months $ 50,344 Greater than 12 months 27,343 Total $ 77,687 Operating Lease Commitments Rental expense under operating lease commitments amounted to $ 6.4 million , $ 5.6 million and $ 5.9 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Minimum rental commitments due under non-cancelable operating leases, primarily for office and warehouse facilities, were as follows at December 31, 2017 (in thousands): 2018 2019 2020 2021 2022 Thereafter Minimum lease commitments $ 12,272 $ 8,431 $ 5,850 $ 4,183 $ 3,350 $ 8,453 Commercial Contract Commitment As of December 31, 2017 , we had approximately $ 112.6 million of commercial contract commitments related to open purchase orders. Insurance We maintain insurance coverage of a type and with such limits as we believe are customary and reasonable for the risks we face and in the industries in which we operate. While many of our policies do contain a deductible, the amount of such deductible is typically not material, and is generally less than $0.4 million per occurrence. Our 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, 2017 . 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, 2017 and 2016 (in thousands): December 31, 2017 2016 Balance beginning January 1 $ 4,559 $ 4,551 Provisions 2,590 2,255 Claims settled (4,508 ) (3,304 ) Acquired reserves/other 1,759 1,125 Currency translation adjustment 223 (68 ) Balance ending December 31 $ 4,623 $ 4,559 Warranty obligations of $4.6 million for the year ended December 31, 2017 were consistent with the prior year. Decreases in warranty obligations of $4.5 million were primarily driven by claims settled within certain Industrial businesses and CFS, were partially offset by $1.8 million of obligations from our 2017 FH acquisition.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Financial Instruments The company utilizes fair value measurement guidance prescribed by accounting standards to value its financial instruments. The guidance establishes a fair value hierarchy based on the inputs used to measure fair value. 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. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The carrying amounts of cash and cash equivalents, 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. As of December 31, 2017 and 2016, the outstanding balance of the Company’s debt approximated fair value based on current rates available to the Company for debt of the same maturity and is a Level 2 financial instrument. Contingent consideration obligations are measured at fair value and are based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions and estimates to forecast a range of outcomes and probabilities for the contingent consideration. Contingent consideration obligations are valued using a Monte Carlo simulation model. We assess these assumptions and estimates on a quarterly basis as additional data impacting the assumptions is obtained. Any changes in the fair value of contingent consideration related to updated assumptions and estimates will be recognized within general and administrative expenses in the consolidated statements of operations during the period in which the change occurs. At December 31, 2016 the fair value was $12.2 million , during the year ended December 31, 2017 the full balance was written off based on actual results and therefore no balance remains at December 31, 2017. The fair values of the Company’s pension plan assets at December 31, 2017 and 2016 , utilizing the fair value hierarchy were as follows (in thousands): December 31, 2017 December 31, 2016 Measured at Net Asset Value (1) Level 1 Level 2 Total Measured at Net Asset Value (1) U.S. Plans: Cash Equivalents: Money Market Funds $ — $ 237 $ — $ 237 $ — Mutual Funds: Bond Funds — — — — 1,721 Large Cap Funds — — — — 15,117 International Funds 4,838 — — 4,838 5,967 Small Cap Funds — — — — 2,960 Blended Funds — — — — 2,185 Mid Cap Funds — — — — 3,826 Comingled Pools: Opportunistic 3,106 — — 3,106 — Investment Grade 10,664 — — 10,664 — Non-U.S. Equity 4,730 — — 4,730 — U.S. Equity 14,773 — — 14,773 — Foreign Plans: Cash — 518 — 518 — Equity 10,499 — 184 10,683 — Non-U.S. government and corporate bonds 15,146 — 669 15,815 — Insurance Contracts 306 — 2,932 3,238 — Other — 38 — 38 — Total Fair Value $ 64,062 $ 793 $ 3,785 $ 68,640 $ 31,776 (1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient (the “NAV”) have not been classified in the fair value hierarchy. These investments, consisting of common/collective trusts, are valued using the NAV provided by the Trustee. The NAV is based on the underlying investments held by the fund, that are traded in an active market, less its liabilities. These investments are able to be redeemed in the near-term. (2) $179 million of pension plan asset receivable has been excluded from the leveling table above as CIRCOR does not yet control the assets the fair value has been determined based on CIRCOR's percent of Colfax U.S. pension plan assets which were valued by Colfax using NAV as described in (1). Contingent consideration obligations are measured at fair value and are based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions and estimates to forecast a range of outcomes and probabilities for the contingent consideration. Contingent consideration obligations are valued using a Monte Carlo simulation model. We assess these assumptions and estimates on a quarterly basis as additional data impacting the assumptions is obtained. Any changes in the fair value of contingent consideration related to updated assumptions and estimates will be recognized within general and administrative expenses in the consolidated statements of operations during the period in which the change occurs. Foreign Currency Contracts 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 our contracts are recognized as a component of other expense in our consolidated statements of income. As of December 31, 2017 , we had no forward contracts. This compares to four forward contracts with a fair value liability of $0.1 million as of December 31, 2016 . Our foreign currency forward contracts fall within Level 2 of the fair value hierarchy, in accordance with ASC Topic 820. The foreign exchange (gains)/losses for the year ended December 31, 2017 , 2016 and 2015 were $0.1 million , $(0.6) million , and $0.5 million , respectively, and are included in other (income) expense in our consolidated statements of income.

Segment Reporting [Abstract]
Segment Information	Segment and Geographical Information At December 31, 2017, the Company’s financial performance is managed and reported in three segments. A description of each segment follows. Our reportable segments have been identified in accordance with ASC 280-10-50 through our evaluation of how the Company engages in business activities to earn revenues and incur expenses, which operating results are regularly reviewed by our 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 we sell our product and services into. No individual operating segments have been aggregated for purposes of determining our reportable segments. Advanced Flow Solutions ("AFS") is a diversified flow control technology platform. Our primary product focus areas are valves, actuation, motors, switches, high pressure pneumatic systems, steam and process loop flow management solutions. AFS products are used in aerospace, defense, power and process, and general industrial markets. These products are primarily focused on the following end markets: Aerospace and Defense, Power and Process, HVAC, Maritime and Industrial Gas. Energy is a global provider of highly engineered integrated flow control solutions, valves and services primarily in the Oil & Gas end market. We are focused on satisfying our customers’ mission-critical application needs by utilizing advanced technologies. Our flow control solutions can withstand extreme temperatures and pressures, including land-based, topside, and sub-sea applications. Fluid Handling is a global portfolio of highly engineered and differentiated fluid handling products, systems and services. Our primary products are positive displacement pumps, specialty centrifugal pumps, and lubrication management systems and services. Segment revenues and income presented below reflect the period from December 11, 2017 to December 31, 2017. Each reporting segment is individually managed, as each requires different technology and marketing strategies, and has separate financial results that are reviewed by our CODM. Our 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. For 2018, we expect to reorganize our segments by end market: Energy, Aerospace & Defense and Industrial. Prior year financial statements will be adjusted to reflect this new organization basis beginning in the first quarter of 2018. 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. 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. Our 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): 2017 2016 2015 Net revenues Energy $ 347,578 $ 322,046 $ 383,655 Advanced Flow Solutions 277,637 268,213 272,612 Fluid Handling 36,495 — — Inter-segment revenues — 994 1,124 Corporate — (994 ) (1,124 ) Consolidated revenues $ 661,710 $ 590,259 $ 656,267 Segment Income Energy - Segment Operating Income $ 30,748 $ 34,619 $ 50,386 Advanced Flow Solutions - Segment Operating Income 37,230 33,463 33,811 Fluid Handling - Segment Operating Income 5,460 — — Corporate expenses (21,744 ) (25,672 ) (21,710 ) Subtotal 51,694 42,410 62,487 Special restructuring charges, net 7,989 8,975 4,634 Special other charges, net 6,063 8,196 9,720 Special and restructuring charges, net 14,052 17,171 14,354 Restructuring related inventory charges — 2,846 9,391 Amortization of inventory step-up 4,300 1,366 Impairment charges — 208 2,502 Acquisition amortization 12,542 9,901 6,838 Acquisition depreciation 233 — — Brazil restatement impact — — 3,228 Restructuring and other cost, net 17,075 14,321 21,959 Consolidated Operating Income 20,568 10,918 26,174 Interest Expense, net (a) 10,777 3,310 2,844 Other Expense (Income), net (a) 3,678 (2,072 ) 902 Income from continuing operations before income taxes $ 6,113 $ 9,680 $ 22,428 Identifiable assets Energy $ 729,087 $ 658,749 $ 463,359 Advanced Flow Solutions 560,726 407,035 486,369 Fluid Handling 1,079,396 — — Corporate $ (462,410 ) (245,028 ) (279,813 ) Consolidated Identifiable assets $ 1,906,799 $ 820,756 $ 669,915 Capital expenditures Energy $ 3,763 $ 3,902 $ 6,176 Advanced Flow Solutions 7,258 8,535 6,324 Fluid Handling 2,147 — — Corporate 1,378 1,775 814 Consolidated Capital expenditures $ 14,546 $ 14,212 $ 13,314 Depreciation and amortization Energy $ 12,537 $ 8,755 $ 7,102 Advanced Flow Solutions 13,481 15,555 15,624 Fluid Handling 2,706 — — Corporate 1,313 1,309 1,209 Consolidated Depreciation and amortization $ 30,037 $ 25,619 $ 23,935 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 $ 15.6 million , $ 50.5 million , and $ 46.7 million as of December 31, 2017 , 2016 and 2015 , 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.

Summary Of Significant Accoun27

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Principles Of Consolidation And Basis Of Presentation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of CIRCOR and its subsidiaries. The results of companies acquired during the year are included in the consolidated financial statements from the date of acquisition. All significant intercompany balances and transactions have been eliminated in consolidation.
Use Of Estimates	Use of Estimates The preparation of these financial statements in conformity with generally accepted accounting principles ("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 relate to acquisition accounting, estimated total costs for ongoing long-term contracts accounted for under the percentage of completion method, inventory valuation, share-based compensation, amortization and impairment of long-lived assets, pension benefits obligations, income taxes, 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.
Revenue Recognition	Revenue Recognition and Accounts Receivable Allowances Revenue is primarily recognized when title and risk of loss have passed to the customer, persuasive evidence of an arrangement exists, no significant post delivery obligations remain, the price to the buyers is fixed or determinable and collection of the resulting receivable is reasonably assured.
Cost Of Revenue	Cost of Revenue Cost of revenue primarily reflects the costs of manufacturing and preparing products for sale and, to a much lesser extent, the costs of performing services. Cost of revenue 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 the manufacturing plant. Additional expenses that directly result from the level of production activity at the manufacturing plant 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 Inventories are stated at the lower of cost or net realizable value. Cost is generally determined on the first-in, first-out (“FIFO”) basis. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual cost. We typically analyze our inventory aging and projected future usage on a quarterly basis to assess the adequacy of our inventory allowance, which primarily consist of obsolescence and net realizable value estimates. These estimates are measured on an item-by-item basis determined based on the difference between the cost of the inventory and estimated market value. The provision for inventory allowance is a component of our cost of revenues. Assumptions about future demand are among the primary factors utilized to estimate market 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.
Penalty Accruals	Penalty Accruals Certain customer agreements, primarily in our long-cycle project related businesses and large aerospace programs, contain late shipment penalty clauses whereby we are contractually obligated to pay consideration to our customers if we do not meet specified shipment dates. The accrual for estimated penalties is shown as a reduction of revenue and is based on several factors including historical customer settlement experience and management’s assessment of specific shipment delay information. Accruals related to these potential late shipment penalties as of December 31, 2017 and 2016 were $2 million and $5 million , respectively. As we conclude performance under these agreements, the actual amount of consideration paid to our customers may vary from the amounts we currently have accrued.
Business Acquisitions	Business Acquisitions We account for business combinations under the acquisition method, and accordingly, the assets and liabilities of the acquired businesses are recorded at their estimated fair value on the acquisition date with the excess of the purchase price over their estimated fair value recorded as goodwill. We determine acquisition related asset and liability fair values through established valuation techniques for industrial manufacturing companies and utilize third party valuation firms to assist in the valuation of certain tangible and intangible assets. The consideration for our acquisitions may include future payments that are contingent upon the occurrence of a particular event. For acquisitions that qualify as business combinations, we record an obligation for such contingent payments at fair value on the acquisition date. We estimate the fair value of contingent consideration obligations through valuation models that incorporate probability adjusted assumptions related to the achievement of the milestones and thus likelihood of making related payments or by using a Monte Carlo simulation model. We revalue these contingent consideration obligations each reporting period. Changes in the fair value of our contingent consideration obligations are recognized within general and administrative expense in our consolidated statements of income. Accounting Standards Codification ("ASC") Topic 805, Business Combinations, provides guidance regarding business combinations and requires acquisition-date fair value measurement of identifiable assets acquired, liabilities assumed, and non-controlling interests in the acquiree. For additional information, refer to Note 3, Business Acquisitions.
Goodwill And Intangible Assets	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. For goodwill, we perform an impairment assessment at the reporting unit level on an annual basis as of the end of our October month end or more frequently if circumstances warrant. Our annual impairment assessment requires a comparison of the fair value of each of our 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, we 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, we estimate the fair value of our reporting units using an income approach based on the present value of future cash flows. We believe this approach yields the most appropriate evidence of fair value. We also utilize the comparable company multiples method and market transaction fair value method to validate the fair value amount we obtain using the income approach. The key assumptions utilized in our discounted cash flow model include our estimates of future cash flows from operating activities offset by estimated capital expenditures of the reporting unit, the estimated terminal value for each reporting unit, a discount rate based on a weighted average cost of capital, and overall economic conditions. Any unfavorable material changes to these key assumptions could potentially impact our fair value determinations. As such, we may experience fluctuations in revenues and operating results resulting in the non-achievement of our estimated growth rates, operating performance and working capital estimates utilized in our discounted cash flow models. For more information related to our Goodwill, see Note 7, Goodwill and Other Intangible Assets. Indefinite-Lived Intangible Assets For intangible assets with indefinite lives, we perform an impairment assessment at the asset level on an annual basis as of the end of our October month end or more frequently if circumstances warrant. Indefinite-lived intangible assets, such as trade names, are generally recorded and valued in connection with a business acquisition. These assets are reviewed at least annually for impairment, or more frequently if facts and circumstances warrant. We also utilized a fair value calculation to evaluate these intangibles. 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, we estimate the fair value using an income approach based on the present value of future cash flows. We note the fair value of each individual indefinite-lived asset exceeded the respective carrying amount, and no intangible impairments were recorded.
Impairment Of Other Long-Lived Assets	Other Long-Lived Assets In accordance with ASC 360, Plant, Property, and Equipment, we perform impairment analyses of our long-lived assets, such as property, plant and equipment, whenever events and circumstances indicate that they may be impaired. When the undiscounted future cash flows are expected to be less than the carrying value of identified asset groupings being reviewed for impairment, the asset groupings are written down to fair value.
Pension Benefits	Post Retirement Benefits Pensions and other post-retirement benefits 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 the assumptions and differences from actual results will affect the amounts of net periodic benefit cost recognized in future periods. These assumptions may also have an effect on 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 CIRCOR and recognized changes in other comprehensive income. Other comprehensive income changes are due to new actuarial gains and losses and 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 life of the employee group. Unrecognized actuarial gains and losses arise from several factors including experience and assumption changes in the benefit obligations and from the difference between expected returns and actual returns on plan assets.
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 we anticipate that it is more likely than not that we 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 our current expectations, our 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, we 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 our 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. For more information related to our Income Taxes, see Note 8, 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 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 excluding the 2013 and 2014 CEO and CFO stock option awards which are valued using the Monte Carlo option pricing model as these are market condition awards. 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 forfeiture assumptions based on an analysis of historical data. Market condition stock option awards include both a service period and a market performance vesting condition. The stock options vest if certain stock price targets are met based on the stock price closing at or above the target for 60 consecutive trading days. Vested options may be exercised 25% at the time of vesting, 50% one year from the date of vesting and 100% two years from the date of vesting. These market condition stock option awards are being expensed utilizing a graded method and are subject to forfeiture in the event of employment termination (whether voluntary or involuntary) prior to vesting. To the extent that the market conditions above (stock price targets) are not met, those options will not vest and will forfeit 5 years from grant date. The Company used a Monte Carlo simulation option pricing model to value these option awards.
Environmental Compliance And Remediation	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 450, Contingencies, estimated costs are based upon current laws and regulations, existing technology and the most probable method of remediation.
Foreign Currency Translation	Foreign Currency Our 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 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. We do not provide for U.S. income taxes on foreign currency translation adjustments since we do not provide for such taxes on undistributed earnings of foreign subsidiaries. Our net foreign exchange losses / (gains) recorded for the years ended December 31, 2017 , 2016 and 2015 were $2.1 million , $2.1 million , and $0.8 million , respectively and are included in other (income) expense in the consolidated statements of income.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share are 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, 2017 2016 2015 Net Income Shares Per Share Amount Net Income Shares Per Share Amount Net Income Shares Per Share Amount Basic EPS $ 11,789 16,674 $ 0.71 $ 10,101 16,418 $ 0.62 $ 9,863 16,850 $ 0.59 Dilutive securities, principally common stock options 175 (0.01 ) 118 (0.01 ) 63 (0.01 ) Diluted EPS $ 11,789 16,849 $ 0.70 $ 10,101 16,536 $ 0.61 $ 9,863 16,913 $ 0.58 Certain stock options to purchase common shares and restricted stock units ("RSUs") were anti-dilutive. There were 252,001 anti-dilutive stock options and RSUs for the year ended December 31, 2017 with exercise prices ranging from $51.84 to $71.56 . There were 36,281 anti-dilutive stock options and RSUs for the year ended December 31, 2016 with exercise prices ranging from $70.42 to $79.33 . There were 297,915 anti-dilutive stock options and RSUs for the year ended December 31, 2015 with exercise prices ranging from $41.17 to $79.33 . As of December 31, 2017 , there were 2,876 outstanding RSUs that contain rights to nonforfeitable dividend equivalents and are considered participating securities that are included in our computation of basic and fully diluted earnings per share.
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 fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). We utilize fair value measurements for forward currency contracts, guarantee and indemnification obligations, certain pension plan assets, and certain intangible assets.
Property, Plant and Equipment	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, 3 to 10 years for manufacturing machinery and equipment, computer equipment and software, and furniture and fixtures. Motor vehicles are depreciated over a range of 2 to 6 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 revenue. Depreciation related to selling and administrative functions is reported in selling, general and administrative expenses.
Research and Development	Research and Development Research and development expenditures, including certain engineering costs, are expensed when incurred and are included in selling, general and administrative expenses.

Brazil Closure: On November 3, 2015, our Board of Directors approved the closure and exit of our Brazil manufacturing operations due to the economic realities in Brazil and the ongoing challenges with our only significant end customer, Petrobras. CIRCOR Brazil reported substantial operating losses every year since it was acquired in 2011 while the underlying market conditions and outlook deteriorated. In connection with the closure, we recorded $0.9 million of charges within the Energy segment during the year ended December 31, 2017, which relates to losses incurred subsequent to our closure of manufacturing operations during the first quarter of 2016. Divestiture: On July 7, 2017, we divested our French non-core aerospace build-to-print business within our Advanced Flow Solutions segment as part of our simplification strategy. We considered this business as non-core because the products or services did not fit our strategy and the long-term profitable growth prospects were below our expectations. Divestiture of this non-core business enables us to focus resources on businesses where there is greater opportunity to achieve sales growth, higher margins, and market leadership. We measured the disposal group at its fair value less cost to sell, which was lower than its carrying value, and recorded a $3.8 million charge during the second quarter of 2017. Also, in connection with this disposition we recorded a $1.5 million of severance included as a restructuring charge. Contingent Consideration Revaluation: The fair value of the earn-out decreased $12.2 million during the twelve months ended December 31, 2017.
