Accounting Policies [Abstract]
Basis of Preparation	Basis of Preparation The accompanying unaudited condensed consolidated financial statements of Chart Industries, Inc. and its consolidated subsidiaries (the “Company” or “Chart”) have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for annual financial statements. These financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . Nature of Operations : Chart Industries, Inc. and its consolidated subsidiaries (herein referred to as the “Company,” “Chart,” or “we”), is a leading diversified global manufacturer of highly engineered equipment for the industrial gas, energy and biomedical industries. Chart’s equipment and engineered systems are primarily used for low-temperature and cryogenic applications utilizing our expertise in cryogenic systems and equipment which operate at low temperatures sometimes approaching absolute zero (0 Kelvin; -273° Centigrade; -459° Fahrenheit). The Company has domestic operations located across United States including principal executive offices located in Georgia, and an international presence in Asia, Australia, Europe, Mexico and South America. Principles of Consolidation: The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Reclassifications: Certain total assets by operating segments and restructuring activities as reported in 2016 were reclassified to conform to the 2017 presentation within the notes to the condensed consolidated financial statements. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. These estimates may also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions. Cash, Cash Equivalents, Restricted Cash, and Restricted Cash Equivalents: The Company considers all investments with an initial maturity of three months or less when purchased to be cash equivalents. See the Debt and Credit Arrangements note for additional information about restricted cash and restricted cash equivalents, which is included in other current assets and other assets in the accompanying condensed consolidated balance sheets. Recently Issued Accounting Standards: In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The ASU expands and enhances hedge accounting to become more closely aligned with an entity’s risk management activities through hedging strategies. The ASU provides changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements and creates more transparency and better understandability around how economic results are presented in the financial statements. In addition, the new guidance makes certain targeted improvements to ease the application of accounting guidance relative to hedge effectiveness. The guidance will be applied prospectively for annual periods and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” The FASB issued the guidance to provide clarity as to when modification accounting should be applied when there is a change to the terms or conditions of a share-based payment award in order to prevent diversity in practice. The ASU requires modification accounting to be applied unless all of the following conditions exist: (1) the fair value (or calculated value or intrinsic value, if such measurement is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such measurement is used) of the original award before the original award is modified; if the modification does not affect any of the inputs to the valuation, the entity is not required to estimate the value immediately before and after the modification; (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award before it was modified; and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award before it was modified. The guidance will be applied prospectively for annual periods and interim periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In March 2017, the FASB issued ASU 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The new guidance requires companies with sponsored defined benefit pension and/or other postretirement benefit plans to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs. The other components of net periodic benefit cost will be presented separately and not included in operating income. In addition, only service costs are eligible to be capitalized as an asset. The standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and the guidance will generally be applied retrospectively, whereas the capitalization of the service cost component will be applied prospectively. Early adoption is permitted with all of the amendments adopted in the same period. If an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The new guidance eliminates the requirement to calculate the implied fair value of goodwill (Step 2 of the current guidance’s goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on current guidance’s Step 1). The guidance will be applied prospectively for annual and interim impairment tests beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The adoption of this ASU would not materially impact the Company’s condensed consolidated financial statements unless Step 1 of the annual goodwill impairment test fails. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The FASB issued the update to clarify how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and the guidance will generally be applied retrospectively. Early adoption is permitted with all of the amendments adopted in the same period. If an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently assessing the effect that the ASU will have on the Company’s condensed consolidated statements of cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The FASB issued the update to require the recognition of lease assets and lease liabilities on the balance sheet of lessees. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. The ASU requires a modified retrospective transition method with the option to elect a package of practical expedients. Early adoption is permitted. The Company expects adoption to increase the assets and liabilities recorded on its condensed consolidated balance sheet and increase the level of disclosures related to leases. The Company also expects that adoption of the new standard will require changes to its internal controls to support recognition and disclosure requirements under the new standard. The Company is currently assessing the effect that the ASU will have on the Company’s condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” and subsequently issued additional guidance that modified ASU 2014-09. ASU 2014-09 and the subsequent modifications are identified as “Accounting Standards Codification (“ASC”) 606.” ASC 606 replaces existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and provides for expanded disclosure requirements. The update requires entities to recognize revenue 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. ASC 606 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. ASC 606 becomes effective for fiscal years beginning after December 15, 2017. The Company plans to adopt ASC 606 as of January 1, 2018 and has developed an implementation plan to adopt ASC 606 using the modified retrospective approach through a cumulative adjustment to retained earnings. As part of the implementation plan, the Company has identified its revenue streams and is in the process of performing contract reviews to assess the impact of ASC 606 on its results of operations. The Company expects to complete the contract reviews in the near future. While the Company continues to assess all impacts of the accounting change, the Company currently believes that the most significant impact will relate to the timing of revenue recognition. The Company expects the majority of revenue that has historically been recognized when products are shipped, title has transferred and collection is reasonably assured will meet the criteria for using point-in-time revenue recognition. The Company also expects that the majority of the revenue that has historically been recognized using the percentage of completion method of accounting will meet the criteria for over time revenue recognition. At this time, the Company has identified the following impacts related to timing of revenue recognition: • Certain operations that have historically recognized revenue at a point-in-time will be required to change to the over time revenue recognition model as certain contracts contain language that meets the over time criteria established in ASC 606. • A portion of the revenue that has been deferred due to the current guidance for bill and hold revenues will be required to be recognized when the manufacturing process has been completed. The Company is in the process of quantifying the above changes but does not expect them to be material to its consolidated financial statements. The Company expects adoption to increase the level of disclosures related to revenue recognition. In addition, the Company is in the process of identifying appropriate changes to its accounting policies, information technology systems, business processes, and internal control over financial reporting to support recognition under the new standard. The Company plans to complete the design of any necessary changes to its business processes, controls and systems and implement the changes over the remainder of 2017. Recently Adopted Accounting Standards: In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The FASB issued the update to clarify how restricted cash or restricted cash equivalents should be presented in the statement of cash flows. The Company early adopted the amendments provided in ASU 2016-18 effective January 1, 2017 as reflected in these condensed consolidated financial statements to provide financial statement users with more transparent disclosure about restricted cash and restricted cash equivalents. The amendments were applied using a retrospective transition method to each period presented. Prior periods were not restated as the impact of adoption of ASU 2016-18 was not material to prior periods. The cash, cash equivalents, restricted cash, and restricted cash equivalents balance included $8,785 of restricted cash and restricted cash equivalents at September 30, 2017 . Restricted cash and restricted cash equivalents are included in other current assets and other assets in the accompanying condensed consolidated balance sheet at September 30, 2017 . In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The FASB issued the update to change certain aspects of accounting for share-based payments to employees. The update eliminated additional paid-in-capital pools and requires all income tax effects of awards to be recognized in the statements of operations when the awards vest or settle. The Company prospectively recognized the excess income tax effects of awards as income tax expense or benefit in the condensed statements of operations and has elected to continue to estimate the number of share-based awards expected to vest rather than electing to account for forfeitures as they occur. In addition, the Company prospectively recognized the excess tax benefits along with other income tax cash flows as an operating activity in the condensed consolidated statements of cash flows. The Company adopted this guidance effective January 1, 2017. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” The amendments require an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this guidance prospectively for the fiscal year beginning January 1, 2017. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements.

Inventory Disclosure [Text Block]	Inventories In January 2017, the Company prospectively adopted the guidance per ASU 2015-11, “Simplifying the Measurement of Inventory.” The Company previously measured its inventory at the lower of cost or market with cost being determined by the first-in, first-out (“FIFO”) method. Based on the new guidance, the Company measures its inventory at the lower of cost or net realizable value with net realizable value being the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements.

Convertible Notes The outstanding aggregate principal amount of the Company’s 2.0% Convertible Senior Subordinated Notes due August 1, 2018 (the “Convertible Notes”) is $250,000 . The Convertible Notes bear interest at a fixed rate of 2.0% per year, payable semiannually in arrears on February 1 and August 1 of each year, and will mature on August 1, 2018. The effective interest rate at issuance was 7.9% . The Convertible Notes are senior subordinated unsecured obligations of the Company and are not guaranteed by any of the Company’s subsidiaries. The Convertible Notes are senior in right of payment to the Company’s future subordinated debt, equal in right of payment with the Company’s future senior subordinated debt, and are subordinated in right of payment to the Company’s existing and future senior indebtedness, including indebtedness under the Company’s existing credit agreement. In connection with the issuance of the Convertible Notes, the Company entered into privately-negotiated convertible note hedge and capped call transactions with affiliates of certain of the underwriters (the “Option Counterparties”). The convertible note hedge and capped call transactions relate to, collectively, 3,622 shares, which represents the number of shares of the Company’s common stock underlying the Convertible Notes, subject to anti-dilution adjustments substantially similar to those applicable to the Convertible Notes. These convertible note hedge and capped call transactions are expected to reduce the potential dilution with respect to the Company’s common stock upon conversion of the Convertible Notes and/or reduce the Company’s exposure to potential cash or stock payments that may be required upon conversion of the Convertible Notes, except, in the case of the capped call transactions, to the extent that the market price per share of the Company’s common stock exceeds the cap price of the capped call transactions. The Company also entered into separate warrant transactions with the Option Counterparties initially relating to the number of shares of the Company’s common stock underlying the convertible note hedge transactions, subject to customary anti-dilution adjustments. The warrant transactions will have a dilutive effect with respect to the Company’s common stock to the extent that the price per share of the Company’s common stock exceeds the strike price of the warrants unless the Company elects, subject to certain conditions, to settle the warrants in cash. These warrants were exercisable as of the issuance date of the Convertible Notes. The cap price of the capped call transactions and the strike price of the warrant transactions was initially $84.96 per share. Proceeds received from the issuance of the warrants totaled approximately $48,848 and were recorded as an addition to additional paid-in-capital. The net cost of the convertible note hedge and capped call transactions, taking into account the proceeds from the issuance of the warrants, was approximately $17,638 . In accordance with ASC 815, contracts are initially classified as equity if (1) the contract requires physical settlement or net-share settlement, or (2) the contract gives the entity a choice of net-cash settlement in its own shares (physical settlement or net-share settlement). The Company concluded that the settlement terms of the convertible note hedge, capped call, and warrant transactions permit net-share settlement. As such, the convertible note hedge, capped call, and warrant transactions were recorded in equity. Upon issuance of the Convertible Notes, the Company bifurcated the $250,000 principal balance of the Convertible Notes into a liability component of $170,885 , which was recorded as long-term debt, and an equity component of $79,115 , which was initially recorded as additional paid-in-capital. The liability component was recognized at the present value of its associated cash flows using a 7.9% straight-debt rate which represented the Company’s interest rate for similar debt instruments at that time without a conversion feature and is being accreted to interest expense over the term of the Convertible Notes. At September 30, 2017 and December 31, 2016 , the carrying amount of the liability component was $238,142 (less debt issuance costs of $592 ) and $228,115 (less debt issuance costs of $1,125 ), respectively, and the unamortized debt discount of the Convertible Notes was $11,858 and $21,885 , respectively. For the three months ended September 30, 2017 and 2016 , interest expense for the Convertible Notes was $4,658 and $4,400 , respectively, which included $3,408 and $3,150 of non-cash interest accretion expense related to the carrying amount of the Convertible Notes, respectively, and $1,250 of cash interest for both periods. For the nine months ended September 30, 2017 and 2016 , interest expense for the Convertible Notes was $13,777 and $13,018 , respectively, which included $10,027 and $9,268 of non-cash interest accretion expense related to the carrying amount of the Convertible Notes, respectively, and $3,750 of 2.0% cash interest for both periods. In accordance with ASC 470-20, which requires issuers to separately account for the liability and equity components of convertible debt instruments that may be settled in cash upon conversion, the Company allocated debt issuance costs to the liability and equity components in proportion to their allocated value. Debt issuance costs were $7,277 , with $2,303 recorded as a reduction in additional paid-in-capital. The remaining balance of $4,974 is being amortized over the term of the Convertible Notes. For the three months ended September 30, 2017 and 2016 , total expense associated with the amortization of these debt issuance costs was $178 for both periods. For the nine months ended September 30, 2017 and 2016 , total expense associated with the amortization of these debt issuance costs was $533 for both periods. Prior to May 1, 2018, the Convertible Notes will be convertible at the option of the holders thereof only under the following circumstances: (1) during any fiscal quarter commencing after September 30, 2011 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price (currently $69.03 ) for the Convertible Notes on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which, as determined following a request by a holder of Convertible Notes as provided in the bond indenture (the “Indenture”), the trading price per $1,000 principal amount of Convertible Notes for each trading day of such Measurement Period was less than 97% of the product of the last reported sale price of the Company’s common stock and the applicable conversion rate for the Convertible Notes on each such trading day; or (3) upon the occurrence of specified corporate events pursuant to the terms of the Indenture. On or after May 1, 2018, until the close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Notes, holders of the Convertible Notes may convert their Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. It is the Company’s intention to settle any excess conversion value in shares of the Company’s common stock. The conversion rate on the Convertible Notes will be subject to adjustment upon the occurrence of certain events, but will not be adjusted for any accrued and unpaid interest. In addition, following the occurrence of a make-whole fundamental change, the Company will, in certain circumstances, increase the conversion rate for a holder that converts its Convertible Notes in connection with such make-whole fundamental change. The Company may not redeem the Convertible Notes prior to maturity. If the Company undergoes a fundamental change, subject to certain conditions, holders may require the Company to purchase the Convertible Notes in whole or in part for cash at a fundamental change purchase price equal to 100% of the principal amount of the Convertible Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. For purposes of calculating earnings per share, if the average market price of the Company’s common stock exceeds the applicable conversion price during the periods reported, shares contingently issuable under the Convertible Notes will have a dilutive effect with respect to the Company’s common stock. The Company reassesses the convertibility of the Convertible Notes and the related balance sheet classification on a quarterly basis. The Convertible Notes are classified as current liabilities at September 30, 2017 as their maturity is within 12 months of the balance sheet date. At the end of the third quarter of 2017, events for early conversion were not met, and thus the Convertible Notes were not convertible as of and for the fiscal quarter beginning October 1, 2017 . There have been no conversions as of the date of this filing. Senior Secured Revolving Credit Facility The Company has a five -year $450,000 senior secured revolving credit facility (the “SSRCF”) which matures on October 29, 2019. The SSRCF includes a $25,000 sub-limit for the issuance of swingline loans and a $100,000 sub-limit to be used for letters of credit. There is a foreign currency limit of $100,000 under the SSRCF which can be used for foreign currency denominated letters of credit and borrowings in a foreign currency, in each case in currencies agreed upon with the lenders. In addition, the facility permits borrowings up to $100,000 made by the Company’s wholly-owned subsidiaries, Chart Industries Luxembourg S.à. r.l. (“Chart Luxembourg”) and Chart Asia Investment Company Limited (“Chart Asia”). The SSRCF also includes an expansion option permitting the Company to add up to an aggregate $200,000 in term loans or revolving credit commitments from its lenders. The Company recorded $2,869 in deferred debt issuance costs associated with the SSRCF which are being amortized over the five -year term of the SSRCF. This balance is recorded in other assets in the condensed consolidated balance sheets. For the three months ended September 30, 2017 and 2016 , total expense associated with the amortization of these debt issuance costs was $143 for both periods. For the nine months ended September 30, 2017 and 2016 , the related financing costs amortization was $430 for both periods. Revolving loans under the SSRCF bear interest, at the applicable Borrower’s election, at either LIBOR or the greatest of (a) the JPMorgan prime rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%, or (c) the Adjusted LIBOR Rate (as defined in the SSRCF) for the relative interest period on such day (or if such day is not a business day, the immediately preceding business day) plus 1% (the “Adjusted Base Rate”), plus a margin that varies with the Company’s leverage ratio. In addition, the Company is required to pay a commitment fee of between 0.25% and 0.40% of the unused revolver balance and a letter of credit participation fee equal to the daily aggregate letter of credit exposure at the rate per annum equal to the Applicable Margin for Eurocurrency Revolving Facility Borrowings (ranging from 1.5% to 2.75% , depending on the leverage ratio calculated at each fiscal quarter end). A fronting fee must be paid on each letter of credit that is issued equal to 0.125% per annum of the stated dollar amount of the letter of credit. Significant financial covenants for the SSRCF include a minimum liquidity requirement equal to the principal amount of the Convertible Notes outstanding six months prior to the maturity date of the Convertible Notes and when holders of the Convertible Notes have the option to require the Company to repurchase the Convertible Notes, a maximum leverage ratio of 3.25 and a minimum interest coverage to EBITDA ratio of 3.0. The required leverage ratio can be relaxed on up to two occasions, upon notification to the lenders, to 3.75 for up to four consecutive fiscal quarters, for acquisitions and plant expansions of $100,000 or greater. The SSRCF contains a number of other customary covenants including, but not limited to, restrictions on the Company’s ability to incur additional indebtedness, create liens or other encumbrances, sell assets, enter into sale and lease-back transactions, make certain payments, investments, loans, advances or guarantees, make acquisitions and engage in mergers or consolidations, and pay dividends or distributions. On September 19, 2017, the Company entered into an amendment (“Amendment No. 2”) to its SSRCF to exclude the acquisition of RCHPH Holdings, Inc. (“Hudson”) (see Business Combinations footnote) from the pro forma leverage ratio requirement of the SSRCF. Concurrently with Amendment No. 2, the Company has exercised its right under the SSRCF to elect an increase in the maximum permissible leverage ratio thereunder to 3.75 for the four fiscal-quarter period ending September 30, 2018. At September 30, 2017 , the Company was in compliance with all covenants. As of September 30, 2017 , there were $300,000 in borrowings outstanding under the SSRCF (“SSRCF Debt”), bearing interest at 4.00% . The Company borrowed against this facility to fund the acquisition of Hudson. For both the three and nine months ended September 30, 2017, interest expense for the SSRCF Debt was $333. The Company had $44,828 in letters of credit and bank guarantees supported by the SSRCF, which had availability of $105,172 at September 30, 2017 . The obligations under the SSRCF are guaranteed by the Company and substantially all of its U.S. subsidiaries and secured by substantially all of the assets of the Company and its U.S. subsidiaries and 65% of the capital stock of the Company’s material non-U.S. subsidiaries (as defined by the SSRCF) that are owned by U.S. subsidiaries. Foreign Facilities – China Chart Cryogenic Engineering Systems (Changzhou) Company Limited (“CCESC”) and Chart Biomedical (Chengdu) Co. Ltd. (“Chengdu”), wholly-owned subsidiaries of the Company, and Chart Cryogenic Distribution Equipment (Changzhou) Company Limited (“CCDEC”), a joint venture of the Company, maintain joint banking facilities (the “China Facilities”) which include a revolving facility with 50.0 million Chinese yuan (equivalent to $7,534 ) in borrowing capacity which can be utilized for either revolving loans, bonds/guarantees, or bank draft acceptances. Any borrowings made by CCESC, CCDEC or Chengdu under the China Facilities are guaranteed by the Company. At September 30, 2017 , there were no borrowings outstanding under the revolving facility, but CCESC and CCDEC had 2.6 million Chinese yuan (equivalent to $386 ), and 0.5 million Chinese yuan (equivalent to $78 ) in bank guarantees, respectively. CCDEC maintains an unsecured credit facility whereby CCDEC may borrow up to 30.0 million Chinese yuan (equivalent to $4,520 ) for working capital purposes. At September 30, 2017 , there was 15.0 million Chinese yuan (equivalent to $2,260 ) outstanding under this facility, bearing interest at 4.35% . CCDEC was negotiating new terms of this facility including a new maturity date as of the end of the third quarter of 2017. CCESC entered into a term loan during the second quarter of 2016. The term loan is secured by certain CCESC land use rights and allows for up to 86.6 million Chinese yuan (equivalent to $13,052 ) in borrowings. The loan has a term of eight years with semi-annual installment payments of at least 10.0 million Chinese yuan and a final maturity date of May 26, 2024. At September 30, 2017 , there was 56.6 million Chinese yuan (equivalent to $8,532 ) outstanding on this loan, bearing interest at 5.39% . Foreign Facilities – Europe Chart Ferox, a.s. (“Ferox”), a wholly-owned subsidiary of the Company, maintains a secured credit facility with capacity of up to 125.0 million Czech koruna (equivalent to $5,680 ) and two secured credit facilities with capacity of up to 5.6 million euros (equivalent to $6,585 ). All three facilities allow Ferox to request bank guarantees and letters of credit. None of these facilities allow revolving credit borrowings. Under two of the facilities, Ferox must pay letter of credit and guarantee fees equal to 0.70% per annum on the face amount of each guarantee or letter of credit, and under one facility, Ferox must pay the letter of credit and guarantee fees equal to 0.50% . Ferox’s land, buildings, and cash collateral secure the credit facilities. As of September 30, 2017 , there were bank guarantees of 147.1 million Czech koruna (equivalent to $6,683 ) supported by the Ferox credit facilities. Chart Luxembourg maintains an overdraft facility with $5,000 in borrowing capacity. There were no borrowings under the Chart Luxembourg facility as of September 30, 2017 . Letters of Credit Chart Energy & Chemicals, Inc. (“Chart E&C”), a wholly-owned subsidiary of the Company, has $6,442 in deposits in a bank outside of the SSRCF to secure letters of credit. The deposits are treated as restricted cash and restricted cash equivalents in the condensed consolidated balance sheets ( $5,445 in other current assets and $997 in other assets at September 30, 2017 ). Fair Value Disclosures The fair value of the Convertible Notes was approximately 99% of their par value and approximately 96% of their par value as of September 30, 2017 and December 31, 2016 , respectively. The Convertible Notes are actively quoted instruments and, accordingly, the fair value of the Convertible Notes was determined using Level 1 inputs as defined in the Fair Value Measurements note. The fair value of the SSRCF Debt as of September 30, 2017 was estimated based on the present value of the underlying cash flows discounted using market interest rates. Under this method, the fair value of the SSRCF Debt approximated its carrying amount as of September 30, 2017. The Company’s SSRCF Debt was valued using observable inputs and, accordingly, the valuation is performed using Level 2 inputs as defined in the Fair Value Measurements note.

Derivative Financial Instruments [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Financial Instruments The Company utilizes certain derivative financial instruments to enhance its ability to manage foreign currency risk that exists as part of ongoing business operations. Derivative instruments are entered into for periods consistent with related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes, nor is it a party to any leveraged derivative instrument. The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases and certain intercompany transactions in the normal course of business. Contracts typically have maturities of less than one year. Principal currencies include the U.S. dollar, the euro, the Japanese yen, the Czech koruna, the Australian dollar, the British pound, the Canadian dollar, and the Chinese yuan. The Company’s foreign currency forward contracts do not qualify as hedges as defined by accounting guidance. Foreign currency forward contracts are measured at fair value and recorded on the condensed consolidated balance sheets as other current assets or liabilities and reported as financial assets and liabilities in the Fair Value Measurements note. Changes in their fair value are recorded in the condensed consolidated statements of operations and comprehensive income as foreign currency gains or losses. The Company’s foreign currency forward contracts are not exchange traded instruments and, accordingly, the valuation is performed using Level 2 inputs as defined in the Fair Value Measurements note. Gains or losses on settled or expired contracts are recorded in the condensed consolidated statements of operations and comprehensive income as foreign currency gains or losses. The changes in fair value with respect to the Company’s foreign currency forward contracts generated a net gain of $65 and a net loss of $32 for the three months ended September 30, 2017 and 2016 , respectively. The changes in fair value with respect to the Company’s foreign currency forward contracts generated a net gain of $267 and a net loss of $130 for the nine months ended September 30, 2017 and 2016 , respectively.

The unaudited supplemental pro forma financial information for the periods presented gives effect to the acquisition as if it had occurred on January 1, 2016. The following adjustments are reflected in the pro forma financial table below: • the effect of decreased interest expense related to the repayment of the Hudson term loan and revolving credit facility, net of the additional borrowing on the Chart senior secured revolving credit facility, • amortization of acquired intangible assets, • step-up depreciation of acquired property, plant and equipment, • inventory fair value step-up amortization expense, • nonrecurring acquisition-related expenses directly attributable to the Hudson acquisition of $15,917 and $16,529 were adjusted out of the pro forma net income attributable to Chart Industries, Inc. for the three and nine months ended September 30, 2017, respectively, and • nonrecurring acquisition-related expenses incurred by Chart directly related to the Hudson acquisition of $7,254 and $8,130 , were adjusted out of the pro forma net income attributable to Chart Industries, Inc. for the three and nine months ended September 30, 2017, respectively. This unaudited pro forma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have resulted had the acquisition been in effect at the beginning of the periods presented.

Business Combinations	Business Combinations Hudson Acquisition On September 20, 2017, the Company and Chart Sully Corporation, a wholly owned subsidiary of the Company (“Merger Sub”), completed the previously announced acquisition of Hudson pursuant to the terms of the Agreement and Plan of Merger, as amended (the “Merger Agreement”), by and between Chart, Merger Sub, Hudson and R/C Hudson Holdings, L.P., solely in its capacity as the Initial Holder Representative under the Merger Agreement. The acquisition was accomplished by the merger of Merger Sub with and into Hudson, with Hudson surviving the merger as a wholly owned subsidiary of the Company (the “Acquisition”). The preliminary estimated Acquisition purchase price was $419,394 , net of cash acquired, including an estimated net working capital adjustment amount of $5,894 , and $3,500 in acquisition-related tax benefits acquired, as defined in the Merger Agreement. The total purchase price is subject to further adjustments. Approximately $300,000 of the purchase price was funded through borrowings under the Company’s senior secured revolving credit facility, and the remainder of the purchase price was funded with cash on hand. Hudson, which has operations in the United States, China and Italy and a joint venture in Mexico, designs, manufactures, sells and services products used in refining, heating, ventilation and air conditioning (HVAC), petrochemical, natural gas, power generation, industrial and commercial end markets. Hudson is a North American leader in air-cooled heat exchangers and a global leader in axial flow cooling fans. Hudson’s results of operations are included in the Company’s Energy & Chemicals (“E&C”) segment since the date of the acquisition. The Company preliminarily allocated the acquisition consideration to tangible and identifiable intangible assets acquired and liabilities assumed based on their preliminary estimated fair values as of the acquisition date. The preliminary fair value of the acquired tangible and identifiable intangible assets were determined based on inputs that are unobservable and significant to the overall fair value measurement. It is also based on estimates and assumptions made by management at the time of the acquisition. As such, this was classified as Level 3 fair value hierarchy measurements and disclosures. The Company estimated the preliminary fair value of acquired unpatented technology and trademarks and trade names using the relief from royalty method. The preliminary fair values of acquired customer backlog and customer relationships were estimated using the multi-period excess earnings method. Under both the relief from royalty and multi-period excess earnings methods, the fair value models incorporate estimates of future cash flows, estimates of allocations of certain assets and cash flows, estimates of future growth rates, and management’s judgment regarding the applicable discount rates to use to discount such estimates of cash flows. The estimated useful lives of identifiable finite-lived intangible assets range from two to 12 years . Hudson complements Chart’s E&C segment with the addition of its Fin-Fan® brand and other air cooled heat exchangers which broaden E&C’s end market diversity from primarily liquefied natural gas, industrial and natural gas to include HVAC, petrochemical and power generation. The addition of Hudson’s fans business, known by the Tuf-Lite® and Cofimco® brands, allows E&C to offer a broader technology solution for Chart’s customers. Management anticipates the combination of strong engineering cultures will continue to further develop full service solutions for Chart’s customers. The preliminary estimated goodwill was established due to the benefits outlined above, as well as the benefits derived from the anticipated synergies of Hudson integrating with Chart’s E&C segment. Goodwill recorded for the Hudson acquisition is not expected to be deductible for tax purposes. The acquisition consideration allocation below is preliminary, pending completion of the fair value analyses of acquired assets and liabilities as well as certain other analyses. The excess of the purchase price over the estimated fair values is assigned to goodwill. As additional information becomes available, the Company may further revise the preliminary acquisition consideration allocation during the remainder of the measurement period, which shall not exceed twelve months from the closing of the acquisition. Any such revisions or changes may be material. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed in the Hudson acquisition: Net assets acquired: Goodwill $ 227,397 Identifiable intangible assets 202,000 Accounts receivable 34,669 Property, plant and equipment 30,590 Inventories 24,900 Other current assets (1) 9,359 Unbilled contract revenue 4,589 Other assets 2,876 Prepaid expenses 873 Deferred tax liabilities (68,559 ) Accounts payable (21,246 ) Customer advances and billings in excess of contract revenue (16,928 ) Accrued salaries, wages and benefits (4,442 ) Other current liabilities (3,984 ) Other long-term liabilities (1,861 ) Current portion of warranty reserve (839 ) Net assets acquired $ 419,394 _______________ (1) Pursuant to the provisions of the Merger Agreement, Hudson deposited $2,343 into a Rabbi Trust which represents amounts payable to eligible parties under Long-Term Incentive Agreements. This balance is treated as restricted cash and restricted cash equivalents in the condensed consolidated balance sheets and is classified as other current assets. Information regarding identifiable intangible assets acquired in the Hudson acquisition is presented below: Weighted-average Estimated Useful Life Preliminary Estimated Asset Fair Value Finite-lived intangible assets: Customer relationships 10 years $ 109,200 Unpatented technology 12 years 19,200 Customer backlog (1) 2 years 1,200 Total finite-lived intangible assets acquired 10 years 129,600 Indefinite-lived intangible assets: Trademarks and trade names 72,400 Total identifiable intangible assets acquired $ 202,000 _______________ (1) Customer backlog acquired is included in “Patents and other” in the Goodwill and Intangible Assets note.

The following table presents pro forma sales, net income attributable to Chart Industries, Inc., and net income attributable to Chart Industries, Inc. per common share data assuming Hudson was acquired at the beginning of the 2016 fiscal year: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Pro forma sales $ 282,432 $ 241,725 $ 824,066 $ 777,671 Pro forma net income attributable to Chart Industries, Inc. 3,888 15,434 5,305 36,341 Pro forma net income attributable to Chart Industries, Inc. per common share, basic $ 0.13 $ 0.50 $ 0.17 $ 1.19 Pro forma net income attributable to Chart Industries, Inc. per common share, diluted $ 0.12 $ 0.50 $ 0.17 $ 1.17 VCT Vogel GmbH Acquisition On August 31, 2017, Chart Germany GmbH, a wholly-owned subsidiary of the Company, acquired 100% of the equity interests of VCT Vogel GmbH (“VCT”) for an estimated purchase price of 3.5 million euros (equivalent to $4,139 ), subject to a working capital adjustment. VCT, located in Gablingen, Germany, services and repairs cryogenic and other mobile gas tank equipment and trucks. VCT also designs, manufactures and sells truck mounted drive and control systems for the operation of cryogenic pumps on trailers, rigid trucks and containers. VCT’s results are included in the Company’s Distribution & Storage (“D&S”) segment from the date of acquisition. Additional information related to the VCT acquisition has not been presented because the impact on the Company’s consolidated results of operations and financial position is not material. Hetsco, Inc. Acquisition On January 13, 2017, the Company acquired 100% of the equity interests in Hetsco, Inc. from Global Power Equipment Group, Inc. for an estimated purchase price of $23,162 , which was paid upon closing. The purchase price allocation reported at March 31, 2017 was preliminary and was based on provisional fair values. During the second quarter, the Company received revised third-party valuations, performed other analyses and recorded $380 in accounts receivable for post-closing adjustments, which resulted in an adjusted net purchase price of $22,782 . No adjustments were made during the third quarter of 2017. The post-closing adjustments and revised fair values resulted in the following adjustments to the net assets acquired: September 30, 2017 Adjustments As Previously Reported March 31, 2017 Goodwill $ 8,849 $ (1,271 ) $ 10,120 Identifiable intangible assets – customer relationships 8,090 810 7,280 Other identifiable intangible assets 1,150 30 1,120 Other net assets 4,693 51 4,642 Net assets acquired $ 22,782 $ (380 ) $ 23,162 The assets acquired and liabilities assumed were recorded at their estimated fair values as of the acquisition date. Hetsco, Inc. is headquartered in Franklin, Indiana and provides emergency, specialty welding and construction services to natural gas processing, petrochemical, and air gas separation industries. Hetsco’s results are included in the Company’s E&C segment from the date of acquisition. Pro-forma information related to the Hetsco, Inc. acquisition has not been presented because the impact on the Company’s consolidated results of operations and financial position is not material. Contingent Consideration The estimated fair value of contingent consideration relating to the 2015 D&S Thermax acquisition was $1,800 at the date of acquisition and was valued according to a discounted cash flow approach, which includes assumptions regarding the probability of achieving certain earnings targets and a discount rate applied to the potential payments. Potential payments may be paid between October 1, 2017 and July 1, 2019 based on the attainment of certain earnings targets. The potential payments related to Thermax contingent consideration are between $0 and $11,288 . Valuations are performed using Level 3 inputs as defined in the Fair Value Measurements note and are evaluated on a quarterly basis based on forecasted sales and earnings targets. Contingent consideration liabilities are classified as other current liabilities and other long-term liabilities in the condensed consolidated balance sheets. Changes in fair value of contingent consideration, including accretion, are recorded as selling, general, and administrative expenses in the condensed consolidated statements of operations and comprehensive income. The following table represents the changes in contingent consideration liabilities: Balance at December 31, 2016 $ 1,923 Decrease in fair value of contingent consideration liabilities (1,622 ) Balance at September 30, 2017 $ 301 For the nine months ended September 30, 2017 , the fair value of contingent consideration decreased by $1,622, which was primarily driven by economic circumstances that significantly reduced the likelihood of achieving certain earnings targets for the duration of the remaining potential payout period. There was no change in contingent consideration for the three months ended September 30, 2017 . For the three and nine months ended September 30, 2016 , the fair value of contingent consideration increased by $75 and $122, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its financial assets and liabilities at fair value on a recurring basis using a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies. The three levels of inputs used to measure fair value are as follows: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflect the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Financial assets and liabilities measured at fair value on a recurring basis and presented in the Company’s condensed consolidated balance sheets are as follows: September 30, 2017 Total Level 2 Level 3 Foreign currency forward contracts $ 20 $ 20 $ — Total financial assets $ 20 $ 20 $ — Foreign currency forward contracts $ 170 $ 170 $ — Contingent consideration liabilities 301 — 301 Total financial liabilities $ 471 $ 170 $ 301 December 31, 2016 Total Level 2 Level 3 Foreign currency forward contracts $ 39 $ 39 $ — Total financial assets $ 39 $ 39 $ — Foreign currency forward contracts $ 92 $ 92 $ — Contingent consideration liabilities 1,923 — 1,923 Total financial liabilities $ 2,015 $ 92 $ 1,923 Refer to the Derivative Financial Instruments note for further information regarding derivative financial instruments and the Business Combinations note for further information regarding contingent consideration liabilities.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded income tax expense of $1,907 and $1,764 in the three months ended September 30, 2017 and 2016 , respectively. The Company recorded income tax expense of $2,346 and $12,829 in the nine months ended September 30, 2017 and 2016 , respectively. The effective income tax rate of 47.5% and 48.6% for the three and nine months ended September 30, 2017 differed from the U.S. federal statutory rate of 35% primarily due to losses incurred by certain of the Company’s Chinese operations for which no benefit was recorded, partially offset by foreign exchange losses realized upon the receipt of previously taxed income, and the effect of income earned by certain of the Company’s international entities operating in lower taxed jurisdictions. The third quarter 2017 effective income tax rate was also impacted by transaction costs incurred with the acquisition of Hudson, a portion of which were non-deductible for U.S. federal income tax purposes. The effective income tax rate of 11.4% and 31.0% for the three and nine months ended September 30, 2016 differed from the U.S. federal statutory rate of 35% primarily due to an insurance settlement for breaches of representations and warranties that resulted in an adjustment to our purchase price of Airsep shares for tax purposes and offset by losses incurred by certain of the Company’s Chinese operations for which no benefit was recorded. As of both September 30, 2017 and December 31, 2016, the Company has a liability for gross unrecognized tax benefits of $710 . This amount includes $535 of unrecognized tax benefits as of September 30, 2017 , which, if ultimately recognized, would reduce the Company’s annual effective income tax rate. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The Company accrued approximately $89 and $86 for the payment of interest and penalties as of September 30, 2017 and December 31, 2016, respectively.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations : Chart Industries, Inc. and its consolidated subsidiaries (herein referred to as the “Company,” “Chart,” or “we”), is a leading diversified global manufacturer of highly engineered equipment for the industrial gas, energy and biomedical industries. Chart’s equipment and engineered systems are primarily used for low-temperature and cryogenic applications utilizing our expertise in cryogenic systems and equipment which operate at low temperatures sometimes approaching absolute zero (0 Kelvin; -273° Centigrade; -459° Fahrenheit). The Company has domestic operations located across United States including principal executive offices located in Georgia, and an international presence in Asia, Australia, Europe, Mexico and South America.
Principles of Consolidation	Principles of Consolidation: The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation.
Reclassifications [Text Block]	Reclassifications: Certain total assets by operating segments and restructuring activities as reported in 2016 were reclassified to conform to the 2017 presentation within the notes to the condensed consolidated financial statements.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. These estimates may also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Cash, Cash Equivalents, Restricted Cash, and Restricted Cash Equivalents: The Company considers all investments with an initial maturity of three months or less when purchased to be cash equivalents. See the Debt and Credit Arrangements note for additional information about restricted cash and restricted cash equivalents, which is included in other current assets and other assets in the accompanying condensed consolidated balance sheets.
New Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Standards: In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The ASU expands and enhances hedge accounting to become more closely aligned with an entity’s risk management activities through hedging strategies. The ASU provides changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements and creates more transparency and better understandability around how economic results are presented in the financial statements. In addition, the new guidance makes certain targeted improvements to ease the application of accounting guidance relative to hedge effectiveness. The guidance will be applied prospectively for annual periods and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” The FASB issued the guidance to provide clarity as to when modification accounting should be applied when there is a change to the terms or conditions of a share-based payment award in order to prevent diversity in practice. The ASU requires modification accounting to be applied unless all of the following conditions exist: (1) the fair value (or calculated value or intrinsic value, if such measurement is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such measurement is used) of the original award before the original award is modified; if the modification does not affect any of the inputs to the valuation, the entity is not required to estimate the value immediately before and after the modification; (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award before it was modified; and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award before it was modified. The guidance will be applied prospectively for annual periods and interim periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In March 2017, the FASB issued ASU 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The new guidance requires companies with sponsored defined benefit pension and/or other postretirement benefit plans to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs. The other components of net periodic benefit cost will be presented separately and not included in operating income. In addition, only service costs are eligible to be capitalized as an asset. The standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and the guidance will generally be applied retrospectively, whereas the capitalization of the service cost component will be applied prospectively. Early adoption is permitted with all of the amendments adopted in the same period. If an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently assessing the effect that the ASU will have on the Company’s financial position, results of operations, and disclosures. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The new guidance eliminates the requirement to calculate the implied fair value of goodwill (Step 2 of the current guidance’s goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on current guidance’s Step 1). The guidance will be applied prospectively for annual and interim impairment tests beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The adoption of this ASU would not materially impact the Company’s condensed consolidated financial statements unless Step 1 of the annual goodwill impairment test fails. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The FASB issued the update to clarify how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and the guidance will generally be applied retrospectively. Early adoption is permitted with all of the amendments adopted in the same period. If an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently assessing the effect that the ASU will have on the Company’s condensed consolidated statements of cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The FASB issued the update to require the recognition of lease assets and lease liabilities on the balance sheet of lessees. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. The ASU requires a modified retrospective transition method with the option to elect a package of practical expedients. Early adoption is permitted. The Company expects adoption to increase the assets and liabilities recorded on its condensed consolidated balance sheet and increase the level of disclosures related to leases. The Company also expects that adoption of the new standard will require changes to its internal controls to support recognition and disclosure requirements under the new standard. The Company is currently assessing the effect that the ASU will have on the Company’s condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” and subsequently issued additional guidance that modified ASU 2014-09. ASU 2014-09 and the subsequent modifications are identified as “Accounting Standards Codification (“ASC”) 606.” ASC 606 replaces existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and provides for expanded disclosure requirements. The update requires entities to recognize revenue 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. ASC 606 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. ASC 606 becomes effective for fiscal years beginning after December 15, 2017. The Company plans to adopt ASC 606 as of January 1, 2018 and has developed an implementation plan to adopt ASC 606 using the modified retrospective approach through a cumulative adjustment to retained earnings. As part of the implementation plan, the Company has identified its revenue streams and is in the process of performing contract reviews to assess the impact of ASC 606 on its results of operations. The Company expects to complete the contract reviews in the near future. While the Company continues to assess all impacts of the accounting change, the Company currently believes that the most significant impact will relate to the timing of revenue recognition. The Company expects the majority of revenue that has historically been recognized when products are shipped, title has transferred and collection is reasonably assured will meet the criteria for using point-in-time revenue recognition. The Company also expects that the majority of the revenue that has historically been recognized using the percentage of completion method of accounting will meet the criteria for over time revenue recognition. At this time, the Company has identified the following impacts related to timing of revenue recognition: • Certain operations that have historically recognized revenue at a point-in-time will be required to change to the over time revenue recognition model as certain contracts contain language that meets the over time criteria established in ASC 606. • A portion of the revenue that has been deferred due to the current guidance for bill and hold revenues will be required to be recognized when the manufacturing process has been completed. The Company is in the process of quantifying the above changes but does not expect them to be material to its consolidated financial statements. The Company expects adoption to increase the level of disclosures related to revenue recognition. In addition, the Company is in the process of identifying appropriate changes to its accounting policies, information technology systems, business processes, and internal control over financial reporting to support recognition under the new standard. The Company plans to complete the design of any necessary changes to its business processes, controls and systems and implement the changes over the remainder of 2017.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently Adopted Accounting Standards: In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The FASB issued the update to clarify how restricted cash or restricted cash equivalents should be presented in the statement of cash flows. The Company early adopted the amendments provided in ASU 2016-18 effective January 1, 2017 as reflected in these condensed consolidated financial statements to provide financial statement users with more transparent disclosure about restricted cash and restricted cash equivalents. The amendments were applied using a retrospective transition method to each period presented. Prior periods were not restated as the impact of adoption of ASU 2016-18 was not material to prior periods. The cash, cash equivalents, restricted cash, and restricted cash equivalents balance included $8,785 of restricted cash and restricted cash equivalents at September 30, 2017 . Restricted cash and restricted cash equivalents are included in other current assets and other assets in the accompanying condensed consolidated balance sheet at September 30, 2017 . In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The FASB issued the update to change certain aspects of accounting for share-based payments to employees. The update eliminated additional paid-in-capital pools and requires all income tax effects of awards to be recognized in the statements of operations when the awards vest or settle. The Company prospectively recognized the excess income tax effects of awards as income tax expense or benefit in the condensed statements of operations and has elected to continue to estimate the number of share-based awards expected to vest rather than electing to account for forfeitures as they occur. In addition, the Company prospectively recognized the excess tax benefits along with other income tax cash flows as an operating activity in the condensed consolidated statements of cash flows. The Company adopted this guidance effective January 1, 2017. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” The amendments require an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this guidance prospectively for the fiscal year beginning January 1, 2017. The adoption of the guidance did not have a material impact on the Company’s condensed consolidated financial statements.

Line of Credit Facility, Covenant Terms			Significant financial covenants for the SSRCF include a minimum liquidity requirement equal to the principal amount of the Convertible Notes outstanding six months prior to the maturity date of the Convertible Notes and when holders of the Convertible Notes have the option to require the Company to repurchase the Convertible Notes, a maximum leverage ratio of 3.25 and a minimum interest coverage to EBITDA ratio of 3.0. The required leverage ratio can be relaxed on up to two occasions, upon notification to the lenders, to 3.75 for up to four consecutive fiscal quarters, for acquisitions and plant expansions of $100,000 or greater. The SSRCF contains a number of other customary covenants,including, but not limited to, restrictions on the Company’s ability to incur additional indebtedness, create liens or other encumbrances, sell assets, enter into sale and lease-back transactions, make certain payments, investments, loans, advances or guarantees, make acquisitions and engage in mergers or consolidations and pay dividends or distributions. On September 19, 2017, the Company entered into an amendment (“Amendment No. 2”) to its SSRCF to exclude the acquisition of RCHPH Holdings, Inc. (“Hudson”) (see Business Combinations footnote) from the pro forma leverage ratio requirement of the SSRCF. Concurrently with Amendment No. 2, the Company has exercised its right under the SSRCF to elect an increase in the maximum permissible leverage ratio thereunder to 3.75 for the four fiscal-quarter period ending September 30, 2018.
