Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The interim condensed consolidated financial statements included herein are unaudited. In the opinion of management, these statements include all adjustments, consisting only of normal, recurring adjustments, necessary for a fair statement of the financial position of Axalta Coating Systems Ltd., a Bermuda exempted company limited by shares, and its consolidated subsidiaries ("Axalta," the "Company," "we," "our" and "us") at June 30, 2021 and December 31, 2020, the results of operations, comprehensive income (loss) and changes in shareholders' equity for the three and six months ended June 30, 2021 and 2020, and cash flows for the six months then ended. All intercompany balances and transactions have been eliminated. These interim unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The interim unaudited condensed consolidated financial statements include the accounts of Axalta and its subsidiaries, and entities in which a controlling interest is maintained. Certain of our joint ventures are accounted for on a one-month lag basis, the effect of which is not material. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for a full year. Summary of Significant Accounting Policies Recently Adopted Accounting Guidance In March 2020, we adopted ASU 2020-04, "Reference Rate Reform" which provides optional expedients exercisable through December 31, 2022 to ease the potential burden in accounting for the effects of reference rate reform on financial reporting. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope,” which clarified the scope and application of the original guidance. As of June 30, 2021, the expedients provided in this standard do not impact the Company. We will continue to monitor for potential impacts on our financial statements. In December 2020, we adopted ASU 2019-12, "Simplifying the Accounting for Income Taxes", which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and updating provisions related to accounting for franchise (or similar) tax partially based on income and interim recognition of enactment of tax law changes. The adoption of this standard did not have a material impact on our financial statements. Risks and Uncertainties In March 2020, the World Health Organization characterized the coronavirus ("COVID-19") a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The rapid spread of the pandemic and the continuously evolving responses to combat it have had a negative impact on the global economy. The Company's results of operations, financial condition and cash flows were significantly impacted during 2020 as a result of the pandemic and we continue to see impacts to our business given the continued significant presence, and actual or potential spread, of the virus globally, as well as preventative measures enacted in certain regions of the world. We are currently unable to fully determine the future impact of COVID-19 on our business, though we believe the pandemic will continue to have a negative effect on our business during 2021, and potentially longer. We are monitoring the progression of the pandemic and its ongoing and potential effect on our financial position, results of operations, and cash flows, which effects could be materially adverse in a particular quarterly reporting period as well as on an annual basis for 2021, and potentially longer.
