Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Tronox Holdings plc (referred to herein as "Tronox", the "Company", "we", "us", or "our") operates titanium-bearing mineral sand mines and beneficiation operations in Australia, South Africa and Brazil to produce feedstock materials that can be processed into TiO2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and Ultrafine© titanium dioxide used in certain specialty applications. It is our long-term strategic goal to be vertically integrated and consume all of our feedstock materials in our own nine TiO2 pigment facilities which we operate in the United States, Australia, Brazil, UK, France, the Netherlands, China and the Kingdom of Saudi Arabia (“KSA”). We believe that vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our coatings and other TiO2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands creates meaningful quantities of Zircon and pig iron, which we also supply to customers around the world. We are a public limited company listed on the New York Stock Exchange and are registered under the laws of England and Wales. Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, considered necessary for a fair statement of its financial position as of March 31, 2022, and its results of operations for the three months ended March 31, 2022 and 2021. Our unaudited condensed consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements, including, among other things, any potential impacts on the economy as a result of macroeconomic conditions, inflationary pressures, political instability, and supply chain disruptions. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform Financial Reporting.” This amendment is elective in nature. Amongst other aspects, this standard provides for practical expedients and exceptions to current accounting standards that reference a rate which is expected to be dissolved (e.g., London Interbank Offered Rate “LIBOR”) as it relates to hedge accounting, contract modifications and other transactions that reference this rate, subject to meeting certain criteria. The standard is effective for all entities as of March 12, 2020 through December 31, 2022. We have conducted an internal assessment to identify items that would be impacted as a result of the dissolution of LIBOR. Based upon this assessment, we have determined that this change will be most impactful to our intercompany debt agreements and interest rate swap agreements. Upon conversion of these benchmark rates, we intend to elect the practical expedients allowed under this standard which is expected to result in an immaterial impact to the financial statements.
