Accounting Policies [Abstract]
Basis of Preparation	Basis of Preparation The accompanying unaudited condensed consolidated financial statements of Chart Industries, Inc. and its consolidated subsidiaries (herein referred to as the “Company,” “Chart,” “we,” “us,” or “our”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) 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 our Annual Report on Form 10-K for the year ended December 31, 2019. 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, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Nature of Operations: We are a leading independent global manufacturer of highly engineered equipment servicing multiple applications in the Energy and Industrial Gas markets. Our unique product portfolio is used in every phase of the liquid gas supply chain, including upfront engineering, service and repair. Being at the forefront of the clean energy transition, Chart is a leading provider of technology, equipment and services related to liquefied natural gas, hydrogen, biogas and CO2 Capture amongst other applications. We are committed to excellence in environmental, social and corporate governance (ESG) issues both for our company as well as our customers. With over 25 global locations from the United States to Asia, Australia, India, Europe and South America, we maintain accountability and transparency to our team members, suppliers, customers and communities. Principles of Consolidation: The unaudited condensed consolidated financial statements include the accounts of Chart Industries, Inc. and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Reclassifications: Certain reclassifications have been made to prior year financial information in the unaudited condensed consolidated financial statements in order to conform to the discontinued operations presented as further discussed in Note 2, “Discontinued Operations.” Use of Estimates: The preparation of financial statements in conformity with GAAP 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. Furthermore, we considered the impact of the COVID-19 pandemic on the use of estimates and assumptions used for financial reporting and determined that there was no adverse material impact to our results of operations for the first nine months of 2020. While our production has been considered “essential” in all locations we operate in, we have experienced, and may again experience in the future, temporary facility closures while awaiting appropriate government approvals in certain jurisdictions. The COVID-19 outbreak could also disrupt our supply chain and materially adversely impact our ability to secure supplies for our facilities, which could materially adversely affect our operations. There may also be long-term effects on our customers in and the economies of affected countries. As a result of these uncertainties, actual results could differ from those estimates and assumptions. If the economy or markets in which we operate remain weak or deteriorate further, our business, financial condition and results of operations may be materially and adversely impacted. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law in the United States. The CARES Act, among other things, includes modifications to net operating loss carryforwards provisions and the net interest expense deduction, and deferment of social security tax payments. At this time, we have not elected to avail ourselves of the CARES Act. We continue to evaluate the provisions of the CARES Act and how certain elections may impact our financial position, results of operations, and disclosures if elected. Share Repurchase Program: On March 11, 2020, our Board of Directors authorized a share repurchase program for up to $75 million of the Company’s common stock over the next twelve months through various means, including open market transactions, block purchases, privately negotiated transactions or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 and Rule 10b5-1 of the Securities Exchange Act of 1934, as amended. During the first quarter of 2020, we repurchased 0.76 shares of our common stock at an average price of $25.40 per share. We suspended the program on March 20, 2020 in light of uncertainty resulting from the COVID-19 pandemic and the desire to conserve cash resources. As of September 30, 2020, we had approximately $55.7 available for additional repurchases under the share repurchase program, although we have no current intentions to recommence repurchases under this program. Recently Issued Accounting Standards (Not Yet Adopted): In August 2020, the FASB issued ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entities Own Equity (Subtopic 815-40). This ASU simplifies accounting for convertible instruments by eliminating two of the three models in ASC 470-20 that require separating embedded conversion features from convertible instruments. The guidance is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted. We expect adoption of this standard to impact accounting for our convertible notes due November 2024. We are currently assessing the effect that this ASU will have on our financial position, results of operations, and disclosures. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU simplifies the accounting for modifying contracts (including those in hedging relationships) that refer to LIBOR and other interbank offered rates that are expected to be discontinued due to reference rate reform. This guidance is effective upon issuance and generally can be applied through December 31, 2022. We expect adoption of this standard to impact accounting for our senior secured revolving credit facility due June 2024. We are currently assessing the effect this ASU will have on our financial position, results of operations, and disclosures. In January 2020, the FASB issued ASU 2020-01, “Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815).” This ASU clarifies the interactions between the measurement alternative in Topic 321, the equity method of accounting in Topic 323 and the application of guidance for certain forward contracts and purchased options that upon settlement or exercise would be accounted for under the equity method of accounting in Topic 815. This guidance is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. We are currently assessing the effect that this ASU will have on our financial position, results of operations, and disclosures. Recently Adopted Accounting Standards: In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” This ASU clarifies the accounting treatment for implementation costs for cloud computing arrangements (hosting arrangements) that is a service contract. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact our financial position, results of operations or disclosures. In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans.” This ASU adds, modifies and clarifies several disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This guidance is effective for fiscal years ending after December 15, 2020. We early adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a significant impact on our 2020 interim disclosures and is not expected to have a significant impact on our annual disclosures. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU adds, modifies and removes several disclosure requirements relative to the three levels of inputs used to measure fair value in accordance with Topic 820, “Fair Value Measurement.” This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We adopted this guidance effective January 1, 2020. The adoption of this guidance did not impact our financial position, results of operations or disclosures. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” and subsequently issued additional guidance that modified ASU 2016-13. ASU 2016-13 and the subsequent modifications are identified as Accounting Standards Codification (“ASC”) 326. The standard requires an entity to change its accounting approach in determining impairment of certain financial instruments, including trade receivables, from an “incurred loss” to a “current expected credit loss” model. The standard is effective for fiscal years beginning after December 15, 2019, including interim periods within such fiscal years. We adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our financial position, results of operations or disclosures. We maintain an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected as discussed in significant accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2019. In addition, we estimate expected credit losses based on historical loss information then adjust the estimates based on current, reasonable and supportable forecast economic conditions.
