Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	General Colfax Corporation (the “Company” or “Colfax”) is a leading diversified industrial technology company that provides air and gas handling and fabrication technology products and services to customers around the world under the Howden and ESAB brands. On December 11, 2017, the Company completed the sale of its Fluid Handling business (“Fluid Handling”) to CIRCOR International, Inc., a Delaware corporation (“CIRCOR” or “the Buyer”), pursuant to a definitive purchase agreement (the Purchase Agreement) signed on September 24, 2017. Accordingly, the accompanying Condensed Consolidated Financial Statements for all periods presented reflect the Fluid Handling business as a discontinued operation. See Note 3, Discontinued Operations, for further information. The Condensed Consolidated Financial Statements included in this quarterly report have been prepared by the Company in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2017 is derived from the Company’s audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted in accordance with the SEC’s rules and regulations for interim financial statements. The Condensed Consolidated Financial Statements included herein should be read in conjunction with the audited financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the “ 2017 Form 10-K”), filed with the SEC on February 16, 2018 . The Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, which consist solely of normal recurring adjustments, necessary to present fairly the Company’s financial position and results of operations as of and for the periods indicated. Intercompany transactions and accounts are eliminated in consolidation. Certain prior period amounts have been reclassified to conform to current year presentations. The Company makes certain estimates and assumptions in preparing its Condensed Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from those estimates. The results of operations for the three months ended March 30, 2018 are not necessarily indicative of the results of operations that may be achieved for the full year. Quarterly results are affected by seasonal variations in the Company’s business. As our air and gas handling customers seek to fully utilize capital spending budgets before the end of the year, usually our shipments peak during the fourth quarter. Also, our European operations typically experience a slowdown during the July, August and December holiday seasons. General economic conditions may, however, impact future seasonal variations.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Pronouncements Accounting Guidance Implemented in 2018 In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The ASU outlines a single set of comprehensive principles for recognizing revenue under U.S. GAAP and supersedes existing revenue recognition guidance. The main principle of the ASU is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company applied the ASU and its related updates on a full retrospective basis as of January 1, 2018. The adoption of the ASU did not have a material impact on the consolidated financial statements; therefore, no cumulative catch-up adjustment was recorded for prior periods. See Note 5, “Revenue”, for additional information. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires various changes to the measurement and disclosure of equity investments. For the Company, the most relevant change under ASU 2016-01 is the elimination of the available-for-sale classification for equity securities with readily determinable fair values. The adoption of the ASU as of January 1, 2018 resulted in a reclassification of a $5.2 million gain, net of tax, on short term investments from Accumulated other comprehensive loss to Retained earnings on the Company’s Condensed Consolidated Financial Statements. Additionally, as a result of the adoption of this ASU, the Company also recognized a $14.7 million loss based on the change in fair value of short term investments in the Condensed Consolidated Statement of Income for the three months ended March 30, 2018. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 203)”. The ASU addresses eight specific cash flow issues and clarifies their presentation and classification in the Statement of Cash Flows. The Company has retrospectively adopted the ASU on its consolidated financial statements as of January 1, 2018. The adoption of the ASU did not have a material impact on the consolidated financial statements. As such, no retrospective adjustment was recorded. In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory”. The ASU eliminates the exception that the tax effects of an intra-entity transfer (sales) are deferred until the transferred asset is sold to a third party or recovered through use. The resulting impact is the recognition of tax expense in the seller’s jurisdiction and any deferred tax asset in the buyer’s jurisdiction in the period the transfer occurs. The new guidance does not apply to intra entity sales of inventory whose tax effects will continue to be deferred until the inventory is sold to a third party. The Company adopted the ASU as of January 1, 2018 using a modified retrospective approach and concluded the ASU had no material impact on the consolidated financial statements; therefore, no cumulative catch-up adjustment was recorded. In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. This ASU requires that the service cost component of net benefit costs of pension and postretirement benefit plans be reported in the same line item as other compensation costs. Other components of net periodic pension cost and net periodic postretirement benefit cost is required to be presented in the income statement separately from the service cost component, and only the service cost is eligible for capitalization. The Company adopted the ASU as of January 1, 2018 retrospectively for the presentation requirements and prospectively for the capitalization of the service cost. The adoption of the ASU did not have a material impact on the consolidated financial statements. No adjustment was recorded as a result of the adoption. On December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 U.S. Tax Cut and Jobs Act (“Tax Act”). SAB 118 allows registrants to include a provisional amount to account for the implications of the Tax Act where a reasonable estimate can be made and requires the completion of the accounting no later than one year from the date of enactment of the Tax Act or December 22, 2018. Accordingly, in its financial statements for the year ended December 31, 2017, the Company included a provisional estimate of approximately $52 million for the transition tax, payable over 8 years. Generally, the foreign earnings subject to the transition tax can be distributed without additional U.S. tax; however, if distributed, the amount could be subject to foreign taxes and U.S. state and local taxes. The Company also included a provisional tax benefit estimate of approximately $55 million for the re-measurement of its U.S. deferred tax assets and liabilities to 21%. We continue to evaluate the implications of the Tax and have not made any adjustments to the provisional amounts recorded in the prior year. Additionally, the Company intends to file its 2017 U.S. income tax return in the fourth quarter of 2018 which may change our tax basis in temporary differences, tax pools, earning and profits and other elements of the income tax effects of the Tax Act estimated as of December 31, 2017. This may result in an adjustment to the tax provision and be reflected as a re-measurement amount recorded in the financial statements during the quarter in which the U.S. tax return is filed. Additionally, the Tax Act subjects the Company to tax on the Global Intangible Low Tax Income (GILTI) earned by certain of its foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. We have included an estimate of GILTI in determining our annual effective tax rate; however, given the complexity of the GILTI provisions, we are still evaluating the effects of the GILTI provisions and have not yet determined our accounting policy. New Accounting Guidance to be Implemented In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. The ASU requires, among other things, a lessee to recognize assets and liabilities associated with the rights and obligations attributable to most leases but also recognize expenses similar to current lease accounting. The ASU also requires certain qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases, along with additional key information about leasing arrangements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The new guidance can be adopted using a modified retrospective transition and provides for certain practical expedients. The Company is in the process of analyzing and updating data previously collected to evaluate the impact of adopting the ASU on its consolidated financial statements, further assessing the related systems required to capture the increased reporting and disclosures requirements, and its use of practical expedients. The Company will apply the ASU and its related updates on a modified retrospective basis as of January 1, 2019.The adoption of the guidance will have a material effect on the consolidated balance sheets, resulting in the recording of an operating lease asset and liability. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. The ASU is effective for fiscal periods beginning after December 15, 2019 and early adoption is permitted. The ASU eliminates the probable initial recognition threshold under current U.S. GAAP and broadens the information an entity must consider when developing its expected credit loss estimates to include forward-looking information. The Company is currently evaluating the impact of adopting the ASU on its consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The ASU amends the current hedge accounting model and eliminates the requirement to separately measure and report hedge ineffectiveness and requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The ASU also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. Companies are required to apply amendments to cash flow and net investment hedge relationship using modified retrospective method and apply prospective method for the presentation and disclosure requirements. The ASU is effective for fiscal periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently evaluating the impact of adopting the ASU on its consolidated financial statements and the timing of adoption. In January 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, which gives entities the option to reclassify to retained earnings the tax effects resulting from the Tax Act related to items stranded in accumulated other comprehensive income. The new guidance may be applied retrospectively to each period in which the effect of the Tax Act is recognized in the period of adoption. The guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and the timing of adoption.

Discontinued Operations [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations Sale of Fluid Handling Business The Company sold its Fluid Handling business to CIRCOR on December 11, 2017. Total consideration for the sale was $864.9 million, consisting of $555.3 million of cash, 3.3 million shares of CIRCOR common stock (“CIRCOR Shares”), and assumption of $168.0 million of net retirement liabilities. $65.0 million of the cash consideration is expected to be collected during the year ending December 31, 2018, of which $7.9 million has been collected during the three months ended March 30, 2018 . Pursuant to the purchase agreement, the Company is prohibited from transferring any of the CIRCOR Shares for a period of six months following the date of closing. The key components of (loss) income from discontinued operations for the three months ended March 30, 2018 and March 31, 2017 were as follows: Three Months Ended March 30, 2018 March 31, 2017 (In thousands) Net sales $ — $ 111,296 Cost of sales — 71,758 Selling, general and administrative expense (1) 2,471 30,363 Divestiture-related expense, net (2) 1,075 850 Restructuring and other related items — 2,327 Operating (loss) income (3,546 ) 5,998 Interest income (3) — 159 (Loss) income from discontinued operations before income taxes (3,546 ) 6,157 Income tax (benefit) expense (709 ) 3,061 (Loss) income from discontinued operations, net of taxes $ (2,837 ) $ 3,096 (1) Pursuant to the Purchase Agreement, the Company retained its asbestos-related contingencies and insurance coverages. However, as the Company did not retain an interest in the ongoing operations of the business subject to the contingencies, the Company has classified asbestos-related activity in its Condensed Consolidated Statements of Income as part of (Loss) income from discontinued operations. See Note 14, “Commitments and Contingencies” for further information. (2) Primarily related to professional and consulting fees associated with the divestiture including due diligence and preparation of regulatory filings, as well as employee benefit arrangements and other disposition-related activities. (3) Interest expense has not been allocated to the discontinued operations. The Company did not have material cash flows for discontinued operations during the three months ended March 30, 2018. Cash provided by operating activities of discontinued operations for the three months ended March 31, 2017 was $22.4 million . Cash used in investing activities of discontinued operations was $3.8 million for the three months ended March 31, 2017 . There are not material items in the accompanying Condensed Consolidated Statements of Income that had been eliminated in consolidation prior to the disposal.

Revenue Recognition, Milestone Method [Line Items]
Revenue from Contract with Customer [Text Block]	Revenue The Company accounts for revenue in accordance with Topic 606, “Revenue from Contracts with Customers,” which the Company adopted on January 1, 2018, using the full retrospective method. Accordingly, the Company recognizes revenue when control of promised goods or services is transferred to the customer. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for transferring the goods or services. The nature of the Company’s contracts gives rise to certain types of variable consideration, including rebates and other discounts. The Company includes estimated amounts of variable consideration in the transaction price to the extent that it is probable there will not be a significant reversal of revenue. Estimates are based on historical or anticipated performance and represent the Company’s best judgment at the time. Any estimates are evaluated on a quarterly basis until the uncertainty is resolved. The Company provides a variety of products and services to its customers. Most of the Company’s contracts consist of a single, distinct performance obligation or promise to transfer goods or services to a customer. For contracts that include multiple performance obligations, the Company allocates the total transaction price to each performance obligation using the Company’s best estimate of the standalone selling price of each identified performance obligation. A majority of revenue recognized by the Company relates to contracts with customers for standard or off-the-shelf products. As control typically transfers to the customer upon delivery of the product in these circumstances, revenue is generally recognized at that point in time. For service contracts, the Company recognizes revenue ratably over the period of performance as the customer simultaneously receives and consumes the benefits of the services provided. The following table disaggregates the Company’s revenue by segment and timing of transfer: Three Months Ended March 30, 2018 March 31, 2017 Fabrication Technology Air and Gas Handling Fabrication Technology Air and Gas Handling (in thousands) Point in time $ 533,013 $ 213,406 $ 460,061 $ 207,174 Over time 260 134,246 — 66,395 Total $ 533,273 $ 347,652 $ 460,061 $ 273,569 In certain contracts, particularly within the Air and Gas Handling segment, the Company is engaged to engineer and build highly-customized, large-scale products and systems. In these circumstances, the Company produces an asset with no alternative use and has a right to payment for performance completed to date. As a result, revenue is recognized over time based on progress to date. To measure progress, the Company uses an input method based on costs incurred relative to total estimated costs. Under this method, contract revenues are recognized over the performance period of the contract. The amount recognized is directly proportionate to the costs incurred as a percentage of total estimated costs for the entirety of the contract. This method requires estimates to determine the appropriate cost and revenue recognition. Significant management judgments and estimates, including estimated costs to complete projects, must be made and used in connection with revenue recognized during each period. Current estimates may be revised as additional information becomes available. The revisions are recorded in income in the period in which they are determined using the cumulative catch-up method of accounting. As of March 30, 2018, the Air and Gas Handling business had $889.5 million of remaining performance obligations, which is also referred to as total backlog. Of that total backlog, the Company expects to recognize approximately 74% as revenue in 2018 and an additional 26% thereafter. Given the nature of these long-term contracts, the Company is often paid at various points throughout the process, based on the contractual terms. The Company applies the available practical expedient involving the existence of a significant financing component. As the Company does not receive payments greater than one year in advance or arrears of revenue recognition, the Company does not consider any arrangements to include financing components. Any recognized revenues in excess of customer billings are recorded as a component of Trade receivables. Billings of customers in excess of recognized revenues are recorded as a component of Customer advances and billings in excess of costs incurred. For long-term contracts, amounts are billed as work progresses, based on the specified timeline included in the contractual terms. Each contract is evaluated individually to determine the net asset or net liability position. As of March 30, 2018 and December 31, 2017, there were $204.3 million and $204.8 million , respectively, of revenues in excess of billings and $95.5 million and $92.0 million , respectively, of billings in excess of revenues on long-term contracts in the Condensed Consolidated Balance Sheets. For contracts recognized at a point in time, revenue recognition and billing typically occur simultaneously. The Company’s Fabrication Technology business formulates, develops, manufactures and supplies consumable products and equipment. The vast majority of total revenue from the Fabrication Technology business is recognized at a point in time. As a result, of the total amount of remaining unsatisfied performance obligations, the majority relate to ship and bill arrangements. Given the nature of this business, the total amount of unsatisfied performance obligations with an original contract duration of greater than one year as of March 30, 2018 is immaterial. In some circumstances for both over time and point in time contracts, customers are billed in advance of revenue recognition, resulting in contract liabilities. As of December 31, 2017 and 2016, total contract liabilities were $130.3 million and $121.4 million , respectively. During the three months ended March 30, 2018 and March 31, 2017, revenue recognized that was included in the contract liability balance at the beginning of each year was $68.3 million and $78.7 million , respectively. Of this total 74.6% and 79.6% , respectively, was related to long-term contracts which have met the criteria for over time recognition. As of March 30, 2018 and March 31, 2017, total contract liabilities were $161.8 million and $117.9 million , respectively. The Company’s incremental costs of obtaining a contract would generally have less than a one-year duration; therefore, the Company applies the practical expedient available and expenses costs to obtain a contract when incurred.

The effective tax rate differs from the 2018 U.S. federal statutory rate of 21% mainly due to a net discrete tax benefit of $6.1 million primarily associated with a South American jurisdiction offset in part by international taxes which are higher than the U.S. tax rate by losses in certain jurisdictions where a tax benefit is not expected to be recognized in 2018 and U.S. tax on certain foreign earnings including GILTI. During the three months ended March 31, 2017 , Income from continuing operations before income taxes was $51.0 million , while the Provision for income taxes was $12.6 million and the effective tax rate was 24.7% . The effective tax rate differs from the 2017 U.S. federal statutory rate of 35% primarily due to international tax rates, which are lower than the U.S. tax rate, offset in part by losses in certain jurisdictions where a tax benefit was not expected to be recognized in 2017 . The provision for income taxes for the three months ended March 31, 2017 includes a $0.9 million net discrete tax benefit primarily associated with a South American jurisdiction.

Because the Company did not retain an interest in the ongoing operations of the divested Fluid Handling business, the retained asbestos-related activity has been classified in its Condensed Consolidated Statements of Operations as a component of (Loss) income from discontinued operations. Asbestos Contingencies Claims activity since December 31 related to asbestos claims is as follows: Three Months Ended March 30, 2018 March 31, 2017 (Number of claims) Claims unresolved, beginning of period 17,737 20,567 Claims filed (1) 1,069 1,200 Claims resolved (2) (739 ) (1,032 ) Claims unresolved, end of period 18,067 20,735 (1) Claims filed include all asbestos claims for which notification has been received or a file has been opened. (2) Claims resolved include all asbestos claims that have been settled, dismissed or that are in the process of being settled or dismissed based upon agreements or understandings in place with counsel for the claimants. The Company’s Condensed Consolidated Balance Sheets included the following amounts related to asbestos-related litigation: March 30, 2018 December 31, 2017 (In thousands) Long-term asbestos insurance asset (1) $ 279,577 $ 284,454 Long-term asbestos insurance receivable (1) 77,170 73,489 Accrued asbestos liability (2) 53,589 50,311 Long-term asbestos liability (3) 303,134 310,326 (1) Included in Other assets in the Condensed Consolidated Balance Sheets. (2) Represents current accruals for probable and reasonably estimable asbestos-related liability costs that the Company believes the subsidiaries will pay, and unpaid legal costs related to defending themselves against asbestos-related liability claims and legal action against the Company’s insurers, which is included in Accrued liabilities in the Condensed Consolidated Balance Sheets. (3) Included in Other liabilities in the Condensed Consolidated Balance Sheets. Management’s analyses are based on currently known facts and assumptions. Projecting future events, such as new claims to be filed each year, the average cost of resolving each claim, coverage issues among layers of insurers, the method in which losses will be allocated to the various insurance policies, interpretation of the effect on coverage of various policy terms and limits and their interrelationships, the continuing solvency of various insurance companies, the amount of remaining insurance available, as well as the numerous uncertainties inherent in asbestos litigation could cause the actual liabilities and insurance recoveries to be higher or lower than those projected or recorded which could materially affect the Company’s financial condition, results of operations or cash flow. Other Litigation Matters The Company is also involved in other pending legal proceedings arising out of the ordinary course of the Company’s business. None of these legal proceedings are expected to have a material adverse effect on the financial condition, results of operations or cash flow of the Company. With respect to these proceedings and the litigation and claims described in the preceding paragraphs, management of the Company believes that it will either prevail, has adequate insurance coverage or has established appropriate accruals to cover potential liabilities. Any costs that management estimates may be paid related to these proceedings or claims are accrued when the liability is considered probable and the amount can be reasonably estimated. There can be no assurance, however, as to the ultimate outcome of any of these matters, and if all or substantially all of these legal proceedings were to be determined adverse to the Company, there could be a material adverse effect on the financial condition, results of operations or cash flow of the Company.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Information The Company conducts its continuing operations through the Air and Gas Handling and Fabrication Technology segments, which also represent the Company’s reportable segments. ▪ Air and Gas Handling - a global supplier of centrifugal and axial fans, rotary heat exchangers, gas compressors, ventilation control systems and software, and aftermarket services; and ▪ Fabrication Technology - a global supplier of welding equipment, cutting equipment, automated welding and cutting systems, and consumables. Certain amounts not allocated to the two reportable segments and intersegment eliminations are reported under the heading “Corporate and other.” The Company’s management evaluates the operating results of each of its reportable segments based upon Net sales and segment operating income, which represents Operating income before Restructuring and other related charges. The Company’s segment results were as follows: Three Months Ended March 30, 2018 March 31, 2017 (In thousands) Net sales: Air and Gas Handling $ 347,652 $ 273,569 Fabrication Technology 533,273 460,061 $ 880,925 $ 733,630 Segment operating income (1) : Air and Gas Handling $ 23,382 $ 22,823 Fabrication Technology 64,138 55,639 Corporate and other (17,419 ) (13,466 ) $ 70,101 $ 64,996 (1) The following is a reconciliation of Income from continuing operations before income taxes to segment operating income: Three Months Ended March 30, 2018 March 31, 2017 (In thousands) Income from continuing operations before income taxes $ 37,865 $ 50,969 Loss on short term investments 14,719 — Interest expense 9,588 9,254 Restructuring and other related charges 7,929 4,773 Segment operating income $ 70,101 $ 64,996

Revenue [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue The Company accounts for revenue in accordance with Topic 606, “Revenue from Contracts with Customers,” which the Company adopted on January 1, 2018, using the full retrospective method. Accordingly, the Company recognizes revenue when control of promised goods or services is transferred to the customer. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for transferring the goods or services. The nature of the Company’s contracts gives rise to certain types of variable consideration, including rebates and other discounts. The Company includes estimated amounts of variable consideration in the transaction price to the extent that it is probable there will not be a significant reversal of revenue. Estimates are based on historical or anticipated performance and represent the Company’s best judgment at the time. Any estimates are evaluated on a quarterly basis until the uncertainty is resolved. The Company provides a variety of products and services to its customers. Most of the Company’s contracts consist of a single, distinct performance obligation or promise to transfer goods or services to a customer. For contracts that include multiple performance obligations, the Company allocates the total transaction price to each performance obligation using the Company’s best estimate of the standalone selling price of each identified performance obligation. A majority of revenue recognized by the Company relates to contracts with customers for standard or off-the-shelf products. As control typically transfers to the customer upon delivery of the product in these circumstances, revenue is generally recognized at that point in time. For service contracts, the Company recognizes revenue ratably over the period of performance as the customer simultaneously receives and consumes the benefits of the services provided. The following table disaggregates the Company’s revenue by segment and timing of transfer: Three Months Ended March 30, 2018 March 31, 2017 Fabrication Technology Air and Gas Handling Fabrication Technology Air and Gas Handling (in thousands) Point in time $ 533,013 $ 213,406 $ 460,061 $ 207,174 Over time 260 134,246 — 66,395 Total $ 533,273 $ 347,652 $ 460,061 $ 273,569 In certain contracts, particularly within the Air and Gas Handling segment, the Company is engaged to engineer and build highly-customized, large-scale products and systems. In these circumstances, the Company produces an asset with no alternative use and has a right to payment for performance completed to date. As a result, revenue is recognized over time based on progress to date. To measure progress, the Company uses an input method based on costs incurred relative to total estimated costs. Under this method, contract revenues are recognized over the performance period of the contract. The amount recognized is directly proportionate to the costs incurred as a percentage of total estimated costs for the entirety of the contract. This method requires estimates to determine the appropriate cost and revenue recognition. Significant management judgments and estimates, including estimated costs to complete projects, must be made and used in connection with revenue recognized during each period. Current estimates may be revised as additional information becomes available. The revisions are recorded in income in the period in which they are determined using the cumulative catch-up method of accounting. As of March 30, 2018, the Air and Gas Handling business had $889.5 million of remaining performance obligations, which is also referred to as total backlog. Of that total backlog, the Company expects to recognize approximately 74% as revenue in 2018 and an additional 26% thereafter. Given the nature of these long-term contracts, the Company is often paid at various points throughout the process, based on the contractual terms. The Company applies the available practical expedient involving the existence of a significant financing component. As the Company does not receive payments greater than one year in advance or arrears of revenue recognition, the Company does not consider any arrangements to include financing components. Any recognized revenues in excess of customer billings are recorded as a component of Trade receivables. Billings of customers in excess of recognized revenues are recorded as a component of Customer advances and billings in excess of costs incurred. For long-term contracts, amounts are billed as work progresses, based on the specified timeline included in the contractual terms. Each contract is evaluated individually to determine the net asset or net liability position. As of March 30, 2018 and December 31, 2017, there were $204.3 million and $204.8 million , respectively, of revenues in excess of billings and $95.5 million and $92.0 million , respectively, of billings in excess of revenues on long-term contracts in the Condensed Consolidated Balance Sheets. For contracts recognized at a point in time, revenue recognition and billing typically occur simultaneously. The Company’s Fabrication Technology business formulates, develops, manufactures and supplies consumable products and equipment. The vast majority of total revenue from the Fabrication Technology business is recognized at a point in time. As a result, of the total amount of remaining unsatisfied performance obligations, the majority relate to ship and bill arrangements. Given the nature of this business, the total amount of unsatisfied performance obligations with an original contract duration of greater than one year as of March 30, 2018 is immaterial. In some circumstances for both over time and point in time contracts, customers are billed in advance of revenue recognition, resulting in contract liabilities. As of December 31, 2017 and 2016, total contract liabilities were $130.3 million and $121.4 million , respectively. During the three months ended March 30, 2018 and March 31, 2017, revenue recognized that was included in the contract liability balance at the beginning of each year was $68.3 million and $78.7 million , respectively. Of this total 74.6% and 79.6% , respectively, was related to long-term contracts which have met the criteria for over time recognition. As of March 30, 2018 and March 31, 2017, total contract liabilities were $161.8 million and $117.9 million , respectively. The Company’s incremental costs of obtaining a contract would generally have less than a one-year duration; therefore, the Company applies the practical expedient available and expenses costs to obtain a contract when incurred.
