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 March 31, 2021 and December 31, 2020, the results of operations, comprehensive loss, changes in shareholders' equity and cash flows for the three months ended March 31, 2021 and 2020. 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 months ended March 31, 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 March 31, 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.

Revenue from Contract with Customer [Abstract]
Revenue	REVENUEConsideration for products in which control has transferred to our customers that is conditional on something other than the passage of time is recorded as a contract asset within prepaid expenses and other current assets on the balance sheet. The contract asset balances at March 31, 2021 and December 31, 2020 were $38.1 million and $37.2 million, respectively. We provide certain customers with incremental up-front consideration, subject to clawback provisions, including Business Incentive Plan assets ("BIPs"), which is capitalized as a component of other assets and amortized over the estimated life of the contractual arrangement as a reduction of net sales. At March 31, 2021 and December 31, 2020, the total carrying value of BIPs were $161.0 million and $165.4 million, respectively, and are presented within other assets on the condensed consolidated balance sheets. For the three months ended March 31, 2021 and 2020, $15.3 million, and $16.9 million, respectively, was amortized and reflected as reductions of net sales in the condensed consolidated statements of operations. The total carrying value of BIPs exclude other upfront incentives made in conjunction with long-term customer commitments of $74.2 million and $79.8 million at March 31, 2021 and December 31, 2020, respectively, which will be repaid in future periods. See Note 16 for disaggregated net sales by end-market.

Restructuring

RESTRUCTURING

In accordance with the applicable guidance for ASC 712, Nonretirement Postemployment Benefits, we accounted for termination benefits and recognized liabilities when the loss was considered probable that employees were entitled to benefits and the amounts could be reasonably estimated.

During the three months ended March 31, 2021 and 2020, we incurred costs for termination benefits of $4.5 million, and $18.5 million, respectively. These amounts are recorded within other operating charges in the condensed consolidated statements of operations. The remaining payments associated with these actions are expected to be substantially completed within 24 months.

The following table summarizes the activity related to termination benefit reserves and expenses from December 31, 2020 to March 31, 2021:


	2021 Activity
Balance at December 31, 2020	$	55.8
Expenses, net of changes to estimates	4.5

Commitments and Contingencies	Mar. 31, 2021
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Guarantees We guarantee certain of our customers’ obligations to third parties, whereby any default by our customers on their obligations could force us to make payments to the applicable creditors. At March 31, 2021 and December 31, 2020, we had outstanding bank guarantees of $8.2 million and $8.5 million, respectively. A portion of our bank guarantees expire between 2021 and 2026, while others do not have specified expiration dates. We monitor the customer obligations and bank guarantees to evaluate whether we have a liability at the balance sheet date. During the three months ended March 31, 2020, we incurred a $1.0 million charge related to our outstanding bank guarantees. We did not have any liabilities related to our outstanding bank guarantees recorded at March 31, 2021 and December 31, 2020. Operational Matter In January 2021, we became aware of an operational matter affecting certain North America Mobility Coatings customer manufacturing sites. The matter involves the use and application of certain of our products in combination with and incorporated within third party products. The matter occurred over a discrete period during the fourth quarter of 2020. When we filed, and as disclosed in, our Annual Report on Form 10-K for the year ended December 31, 2020, we estimated that it was reasonably possible that losses associated with the matter could have been up to $250 million. Based on further developments since the filing of our Annual Report on Form 10-K, we have concluded that losses from this matter are probable and, therefore, recorded a charge of $94.4 million for such probable losses during the three months ended March 31, 2021. The recorded probable losses are an estimate and actual costs arising from this matter could be materially lower or higher depending on the actual costs incurred to repair the impacted products. Based on the information currently available surrounding the full scope and associated responsibilities among relevant parties, we believe it is reasonably possible that we could incur losses in addition to the recorded probable losses of up to $65 million. We maintain insurance, with significant policy limits, that could provide coverage for the liabilities or other losses that may arise from this matter. We have submitted an insurance claim, and discussions with our insurers are ongoing. No agreement or resolution has been reached. Other We are subject to various pending lawsuits, legal proceedings and other claims in the ordinary course of business, including civil, regulatory and environmental matters. These matters may involve third-party indemnification obligations and/or insurance covering all or part of any potential damage incurred by us. All of these matters are subject to many uncertainties and, accordingly, we cannot determine the ultimate outcome of the proceedings and other claims at this time. The potential effects, if any, on our consolidated financial statements will be recorded in the period in which these matters are probable and estimable. Except as set forth in the "Operational Matter" section above, we believe that any sum we may be required to pay in connection with proceedings or claims in excess of the amounts recorded would likely not have a material adverse effect upon our results of operations, financial conditions or cash flows on a consolidated annual basis but could have a material adverse impact in a particular quarterly reporting period. We are involved in environmental remediation and ongoing compliance activities at several sites. The timing and duration of remediation and ongoing compliance activities are determined on a site by site basis depending on local regulations. The liabilities recorded represent our estimable future remediation costs and other anticipated environmental liabilities. We have not recorded liabilities at sites where a liability is probable, but that a range of loss is not reasonably estimable. We believe that any sum we may be required to pay in connection with environmental remediation matters in excess of the amounts recorded would likely occur over a period of time and would likely not have a material adverse effect upon our results of operations, financial condition or cash flows on a consolidated annual basis but could have a material adverse impact in a particular quarterly reporting period.

Income Taxes

INCOME TAXES

Our effective income tax rates for the three months ended March 31, 2021 and 2020 are as follows:


	Three Months Ended March 31,
	2021		2020
Effective Tax Rate	19.5	%	(88.5)	%

The Company's effective tax rate for the periods reflected in the condensed consolidated financial statements are not directly comparable primarily due to the intra-entity asset transfers of certain of its intellectual property and the impacts of certain ongoing tax audits, which occurred during the three months ended March 31, 2020 and are discussed below.

On January 1, 2020, we completed an intra-entity transfer of certain intellectual property rights (the “IP”) to our Swiss subsidiary, where our EMEA regional headquarters is located. The transfer of the IP did not result in a taxable gain; however, it did result in step-up of the Swiss tax-deductible basis in the transferred assets and, accordingly, created a temporary difference between the book basis and the tax basis of the IP, which was transferred at fair value. We applied significant judgment when determining the fair value of the IP, which serves as the tax basis of the deferred tax asset. Consequently, this transaction resulted in the recognition of a deferred tax asset at the applicable Swiss tax rate, resulting in a one-time tax benefit of $50.5 million during the three months ended March 31, 2020. The Company expects to be able to realize the deferred tax assets resulting from these intra-entity asset transfers.

In connection with the income tax audit in Germany for the tax period 2010-2013, the Germany Tax Authority (“GTA”) indicated that it believed that certain positions taken on the 2010-2013 corporate income tax returns were not in compliance with German tax law. While the Company disagrees with the conclusions of the GTA based on the technical merits of our positions, after extensive discussions with the GTA and to avoid a potentially long and costly litigation process, in March 2020 the Company expressed a willingness to settle with the GTA on certain matters and expects to reach a formal agreement in the coming months. As a result of these changes, the Company recorded a charge to income tax expense of $14.3 million during the three months ended March 31, 2020. The Company is also currently under audit in Germany for tax years 2014-2017 and is prepared to vigorously defend itself on these matters.

The Company anticipates that it is reasonably possible it will settle up to $11.8 million, exclusive of interest and penalties, of its current unrecognized tax benefits within 2021 due to the conclusion of the 2010-2013 German income tax audit.

Net Income Per Common Share

Mar. 31, 2021

Earnings Per Share [Abstract]

Net Income Per Common Share

NET INCOME PER COMMON SHARE

Basic net income per common share excludes the dilutive impact of potentially dilutive securities and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per common share includes the effect of potential dilution from the hypothetical exercise of outstanding stock options and vesting of restricted shares and performance shares. A reconciliation of our basic and diluted net income per common share is as follows:


	Three Months Ended March 31,
(In millions, except per share data)		2021		2020
Net income to common shareholders		$	15.2	$	52.2
Basic weighted average shares outstanding		233.9		234.9
Diluted weighted average shares outstanding		234.7		235.9
Net income per common share:
Basic net income per share		$	0.06	$	0.22
Diluted net income per share		$	0.06	$	0.22

The number of anti-dilutive shares that have been excluded in the computation of diluted net income per share for the three months ended March 31, 2021 and 2020 were 1.5 million and 2.6 million, respectively.

FINANCIAL INSTRUMENTS, HEDGING ACTIVITIES AND FAIR VALUE MEASUREMENTS

Fair value of financial instruments

Equity securities with readily determinable fair values - Balances of equity securities are recorded within other assets, with any changes in fair value recorded within other income, net. The fair values of equity securities are based upon quoted market prices, which are considered Level 1 inputs.

Long-term borrowings - The estimated fair values of these borrowings are based on recent trades, as reported by a third-party pricing service. Due to the infrequency of trades, these inputs are considered to be Level 2 inputs.

Derivative instruments - The Company’s interest rate caps, interest rate swaps, cross-currency swaps, and foreign currency forward contracts are valued using broker quotations, or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are included in the Level 2 hierarchy.

The table below presents the fair values of our financial instruments measured on a recurring basis by level within the fair value hierarchy at March 31, 2021 and December 31, 2020.

(2) Net investment hedge

Derivative Financial Instruments

We selectively use derivative instruments to reduce market risk associated with changes in foreign currency exchange rates and interest rates. The use of derivatives is intended for hedging purposes only, and we do not enter into derivative instruments for speculative purposes.

The following table presents the fair values of derivative instruments that qualify and have been designated as cash flow and net investment hedges included in accumulated other comprehensive loss ("AOCI"):


	March 31, 2021		December 31, 2020
AOCI:
Interest rate caps (cash flow hedges)	$	2.0	$	2.6
Interest rate swaps (cash flow hedges)	51.5		60.0
Foreign currency forward contracts (cash flow hedges)	0.2		0.3
Cross-currency swaps (net investment hedges)	10.4		35.2
Total AOCI	$	64.1	$	98.1

Gains and losses on the derivative representing hedge components excluded from the assessment of effectiveness are recognized over the life of the hedge on a systematic and rational basis.

The following tables set forth the locations and amounts recognized during the three months ended March 31, 2021 and 2020 for these cash flow and net investment hedges.


		For the Three Months Ended March 31,
		2021				2020
Derivatives in Cash Flow and Net Investment Hedges	Location of Loss (Gain) Recognized in Income on Derivatives	Net Amount of Gain Recognized in OCI on Derivatives		Amount of Loss (Gain) Recognized in Income		Net Amount of Loss (Gain) Recognized in OCI on Derivatives		Amount of Loss (Gain) Recognized in Income
Interest rate caps	Interest expense, net	$	—	$	0.6	$	1.1	$	0.3

Foreign currency forward contracts	Cost of goods sold	(0.1)		—		—		—
Cross-currency swaps	Interest expense, net	(29.6)		(4.8)		(22.5)		(3.7)

Over the next 12 months, we expect losses of $31.0 million pertaining to cash flow hedges to be reclassified from AOCI into earnings, related to our interest rate caps, interest rate swaps, and foreign currency forward contracts.

Derivative Instruments Not Designated as Cash Flow Hedges

We periodically enter into foreign currency forward and option contracts to reduce market risk and hedge our balance sheet exposures and cash flows for subsidiaries with exposures denominated in currencies different from the functional currency of the relevant subsidiary. These contracts have not been designated as hedges and all gains and losses are marked to market through other income, net in the condensed consolidated statement of operations.

Fair value gains and losses of derivative contracts, as determined using Level 2 inputs, that have not been designated for hedge accounting treatment are recorded in earnings as follows:

Segment Reporting [Abstract]

Segments

SEGMENTS

The Company identifies an operating segment as a component: (i) that engages in business activities from which it may earn revenues and incur expenses; (ii) whose operating results are regularly reviewed by the Chief Operating Decision Maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance; and (iii) that has available discrete financial information.

We have two operating segments, which are also our reportable segments: Performance Coatings and Mobility Coatings. Previously named Transportation Coatings, our Mobility Coatings segment was renamed during the three months ended March 31, 2021 with no changes to the underlying business or segment structure. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Our CODM is identified as the Chief Executive Officer because he has final authority over performance assessment and resource allocation decisions. Our segments are based on the type and concentration of customers served, service requirements, methods of distribution and major product lines.

Through our Performance Coatings segment, we provide high-quality liquid and powder coatings solutions to a fragmented and local customer base. We are one of only a few suppliers with the technology to provide precise color matching and highly durable coatings systems. The end-markets within this segment are refinish and industrial.

Through our Mobility Coatings segment, we provide advanced coating technologies to OEMs of light and commercial vehicles. These increasingly global customers require a high level of technical support coupled with cost-effective, environmentally responsible coatings systems that can be applied with a high degree of precision, consistency and speed. The end-markets within this segment are light vehicle and commercial vehicle.

Adjusted EBIT is the primary measure to evaluate financial performance of the operating segments and allocate resources. Asset information is not reviewed or included with our internal management reporting. Therefore, the Company has not disclosed asset information for each reportable segment. The following table presents relevant information of our reportable segments.

(1)			The primary measure of segment operating performance is Adjusted EBIT, which is defined as net income before interest, taxes and select other items impacting operating results. These other items impacting operating results are items that management has concluded are (1) non-cash items included within net income, (2) items the Company does not believe are indicative of ongoing operating performance or (3) non-recurring, unusual or infrequent items that have not occurred within the last two years or we believe are not reasonably likely to recur within the next two years. Adjusted EBIT is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts and prior year financial results, providing a measure that management believes reflects the Company’s core operating performance, which represents Adjusted EBIT adjusted for the select items referred to above.

(2)			Does not represent Axalta’s Adjusted EBIT referenced elsewhere by the Company as there are additional adjustments that are not allocated to the segments.

(a)			Represents expenses and associated changes to estimates related to the prepayment, restructuring, and refinancing of our indebtedness, which are not considered indicative of our ongoing operating performance.

(b)			Represents expenses and associated changes to estimates related to employee termination benefits and other employee-related costs. Employee termination benefits are primarily associated with Axalta Way initiatives. These amounts are not considered indicative of our ongoing operating performance.

(c)			Represents costs for legal, tax and other advisory fees pertaining to our review of strategic alternatives that was concluded in March 2020, as well as retention awards for certain employees which will be earned over a period of 18-24 months, ending September 2021. These amounts are not considered indicative of our ongoing performance.

(d)			Represents acquisition and divestiture-related expenses, all of which are not considered indicative of our ongoing operating performance.

(e)			Represents impairment charges, which are not considered indicative of our ongoing performance.

(f)			Represents certain defined benefit pension costs associated with special events, including pension curtailments, settlements and special termination benefits, which we do not consider indicative of our ongoing operating performance.

(g)			Represents incremental depreciation expense resulting from truncated useful lives of the assets impacted by our manufacturing footprint assessments, which we do not consider indicative of our ongoing operating performance.

(h)			Represents expenses and probable liabilities associated with the operational matter in the Mobility Coatings segment discussed further in Note 5, which is not indicative of our ongoing operating performance.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Recently Adopted Accounting Guidance	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 March 31, 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.

Income before income taxes		$	19.5	$	27.8


(1)			The primary measure of segment operating performance is Adjusted EBIT, which is defined as net income before interest, taxes and select other items impacting operating results. These other items impacting operating results are items that management has concluded are (1) non-cash items included within net income, (2) items the Company does not believe are indicative of ongoing operating performance or (3) non-recurring, unusual or infrequent items that have not occurred within the last two years or we believe are not reasonably likely to recur within the next two years. Adjusted EBIT is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts and prior year financial results, providing a measure that management believes reflects the Company’s core operating performance, which represents Adjusted EBIT adjusted for the select items referred to above.

(2)			Does not represent Axalta’s Adjusted EBIT referenced elsewhere by the Company as there are additional adjustments that are not allocated to the segments.

(a)			Represents expenses and associated changes to estimates related to the prepayment, restructuring, and refinancing of our indebtedness, which are not considered indicative of our ongoing operating performance.

(b)			Represents expenses and associated changes to estimates related to employee termination benefits and other employee-related costs. Employee termination benefits are primarily associated with Axalta Way initiatives. These amounts are not considered indicative of our ongoing operating performance.

(c)			Represents costs for legal, tax and other advisory fees pertaining to our review of strategic alternatives that was concluded in March 2020, as well as retention awards for certain employees which will be earned over a period of 18-24 months, ending September 2021. These amounts are not considered indicative of our ongoing performance.

(d)			Represents acquisition and divestiture-related expenses, all of which are not considered indicative of our ongoing operating performance.

(e)			Represents impairment charges, which are not considered indicative of our ongoing performance.

(f)			Represents certain defined benefit pension costs associated with special events, including pension curtailments, settlements and special termination benefits, which we do not consider indicative of our ongoing operating performance.

(g)			Represents incremental depreciation expense resulting from truncated useful lives of the assets impacted by our manufacturing footprint assessments, which we do not consider indicative of our ongoing operating performance.

(h)			Represents expenses and probable liabilities associated with the operational matter in the Mobility Coatings segment discussed further in Note 5, which is not indicative of our ongoing operating performance.

- Definition

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.
