Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Presentation of Condensed Consolidated Financial Statements - In the opinion of Linde management, the accompanying condensed consolidated financial statements include all adjustments necessary for a fair presentation of the results for the interim periods presented and such adjustments are of a normal recurring nature. The accompanying condensed consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements of Linde plc and subsidiaries in Linde's 2019 Annual Report on Form 10-K. There have been no material changes to the company’s significant accounting policies during 2020. Accounting Standards Implemented in 2020 •Credit Losses on Financial Instruments –In June 2016, the FASB issued updated guidance on the measurement of credit losses. The guidance introduces a new accounting model for expected credit losses on financial instruments, including trade receivables, based on estimates of current expected credit losses. This guidance is effective for the company beginning in the first quarter 2020 and requires companies to apply the change in accounting on a modified retrospective basis. The adoption of the guidance had an immaterial impact on the consolidated financial statements. •Simplifying the Test for Goodwill Impairment – In January 2017, the FASB issued updated guidance on the measurement of goodwill. The new guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. The guidance is effective for the company beginning in the first quarter 2020. The adoption of the guidance had no impact on the consolidated financial statements. •Fair Value Measurement Disclosures - In August 2018, the FASB issued guidance that modifies the disclosure requirements for fair value measurements. The guidance is effective in fiscal year 2020, with early adoption permitted. Certain amendments must be applied prospectively while other amendments must be applied retrospectively. The adoption of the guidance had an immaterial impact on the consolidated financial statements. Accounting Standards to be Implemented •Retirement Benefit Disclosures - In August 2018, the FASB issued guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. For Linde, the guidance is effective for the year ending December 31, 2020 and must be applied on a retrospective basis. The company is evaluating the impact this guidance will have on the disclosures in the notes to the consolidated financial statements. Reclassifications – Certain prior periods' amounts have been reclassified to conform to the current year’s presentation. Other Developments While the events surrounding the COVID-19 pandemic continued to evolve during the first six months of 2020 Linde's primary focus was, and continues to be, the health and safety of its employees and the needs of its customers. The spread of COVID-19 has caused the company to modify its business practices (including employee travel, employee work locations, and cancellation of physical participation in meetings and events), and the company may take further actions if required by government authorities or that it determines are in the best interests of the company's employees, customers, suppliers and other stakeholders. The ultimate magnitude of COVID-19, including the extent of its impact on the company’s operational results, which could be material, will be determined by the length of time that such circumstances continue, measures taken to prevent its spread, and the demand for the company’s products and services, as well as the effect of governmental and public actions taken in response.
