Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Tronox Holdings plc (referred to herein as "Tronox", "we", "us", or "our") operates titanium-bearing mineral sand mines and smelter operations in Australia, South Africa and Brazil to produce feedstock materials that can be processed into TiO 2 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 TiO 2 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 TiO 2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands creates meaningful quantities of zircon, which we also supply to customers around the world. We are a public limited company registered under the laws of England and Wales. Tronox was formerly listed on the New York Stock Exchange as Tronox Limited, a company registered under the laws of Western Australia. However, in March 2019, we re-domiciled to the United Kingdom, and as a result of the re-domiciling, Tronox Limited became a wholly-owned subsidiary of Tronox Holdings plc. Another significant corporate milestone occurred on April 10, 2019 when we completed the acquisition from National Industrialization Company ("Tasnee") of the TiO 2 business of The National Titanium Dioxide Company Limited (“Cristal”) (the “Cristal Transaction”). The Cristal Transaction doubled our size and expanded the number of TiO 2 pigment facilities we operate from three to nine and gave us control of several new mines, particularly in Australia. In order to obtain regulatory approval for the Cristal Transaction, we were required to divest Cristal's North American TiO 2 business, which was sold in May 2019. See Note 2 for further details on the Cristal Transaction. 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, 2019. The acquisition of Cristal has impacted the comparability of our financial statements. As the Cristal Transaction was completed on April 10, 2019, in accordance with ASC 805, the nine month period ended September 30, 2019 includes the results of the Cristal business since the date of the acquisition, while both the three month periods ended September 30, 2020 and September 30, 2019 and the nine month period ended September 30, 2020 include the results of the combined business. 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 September 30, 2020, and its results of operations for the three and nine months ended September 30, 2020 and 2019. 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 any potential impacts on the economy as a result of the Covid-19 pandemic which could impact revenue growth and collectibility of trade receivables. Recently Adopted Accounting Pronouncements 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. The standard modifies the disclosure requirements in Topic 820, Fair Value Measurement, by: removing certain disclosure requirements related to the fair value hierarchy; modifying existing disclosure requirements related to measurement uncertainty; and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019, with early adoption permitted. We adopted this standard on January 1, 2020 and it did not have a material impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), as amended. The standard introduces a new accounting model for expected credit losses on financial instruments, including trade receivables, based on estimates of current expected credit losses (CECL). This standard became effective on January 1, 2020, and had an immaterial impact on the Company's consolidated financial statements as our historical bad debt expense has not been material.

Business Combinations [Abstract]
Acquisitions and Related Divestitures	Acquisitions and Related Divestitures TTI Acquisition In May 2020, the Company announced that it had signed a definitive agreement to acquire the Tizir Titanium and Iron ("TTI") business from Eramet S.A. for approximately $300 million in cash, plus 3% per annum which accrues for the period from January 1, 2020 until the transaction closes. TTI is a titanium smelter located in Tyssedal, Norway which upgrades ilmenite to produce high-grade titanium slag and high-purity pig iron with an annual capacity of approximately 230,000 tons and 90,000 tons, respectively. Pursuant to the definitive agreement, we are required to pay to Eramet S.A. a termination fee of $18 million if the agreement is terminated as a result of a failure to satisfy certain regulatory approvals prior to May 13, 2021 (the “Initial Long Stop Date”) or if all conditions to closing have been satisfied by such date, but we fail to comply with our completion obligations. The definitive agreement further provides that the Initial Long Stop Date may be extended by us until August 13, 2021 and then November 13, 2021 (each a “Long Stop Date Extension”), and that the termination payment shall be increased by $1 million following each Long Stop Date Extension, provided that the amount of such termination payment shall not exceed $20 million. During the second quarter of 2020, upon signing of the definitive agreement to acquire TTI, we placed $18 million into an escrow account with a third-party financial institution. At September 30, 2020, the amount is reflected within “Restricted cash” on the unaudited Condensed Consolidated Balance Sheet. The closing of the transaction, which we anticipate to occur before the Initial Long Stop Date, is subject to certain consents and customary closing conditions, including regulatory approvals. Cristal Acquisition and related divestitures On April 10, 2019, we completed the acquisition of the TiO 2 business of Cristal for $1.675 billion of cash, plus 37,580,000 ordinary shares. The total acquisition price, including the value of the ordinary shares at $14 per share on the closing date of the Cristal Transaction, was approximately $2.2 billion. With the acquisition of our shares, an affiliate of Cristal became our largest shareholder. At September 30, 2020, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a wholly-owned subsidiary of The National Titanium Dioxide Company Limited, continues to own 37,580,000 shares of Tronox, or a 26% ownership interest. The National Titanium Dioxide Company Limited is 79% owned by Tasnee. In order to obtain regulatory approval for the Cristal Transaction, the FTC required us to divest Cristal's North American TiO2 business, which we sold to INEOS on May 1, 2019, for cash proceeds, net of transaction costs, of $701 million, inclusive of an amount for a working capital adjustment. In conjunction with the Cristal Transaction, we entered into a transition services agreement with Tasnee and certain of its affiliates under which we and the Tasnee entities will provide certain transition services to one another. See Note 21 for further details of the transition services agreement. In conjunction with the divestiture of Cristal's North American TiO 2 business to INEOS, we entered into a two-year transition services agreement with INEOS. Under the terms of the transition services agreement, INEOS agreed to provide services to Tronox for manufacturing, technology and innovation, information technology, finance, warehousing and human resources. Similarly, Tronox agreed to provide services to INEOS for information technology, finance, product stewardship, warehousing and human resources. In addition, in order to obtain regulatory approval by the European Commission, we divested the 8120 paper laminate grade, supplied from our Botlek facility in the Netherlands, to Venator Materials PLC (“Venator”). The divestiture was completed on April 26, 2019. Under the terms of the divestiture, we will supply the 8120 grade product to Venator under a supply agreement for an initial term of 2 years, and extendable up to 3 years, to allow for the transfer of the manufacturing of the 8120 grade to Venator. Total cash consideration is 8 million Euros, of which 1 million Euros was paid at the closing and 3.5 million Euros (or approximately $3.9 million) was received during the second quarter of 2020. The remaining 3.5 million Euros (or approximately $4.1 million at September 30, 2020 exchange rate) will be paid in the second quarter of 2021. We recorded a charge of $19 million during the second quarter of 2019, in “Contract loss” in the Consolidated Statements of Operations, reflecting both the proceeds on sale and the estimated losses we expect to incur under the supply agreement with Venator. We funded the cash portion of the Cristal Transaction through existing cash, borrowings from our Wells Fargo Revolver, and restricted cash which had been borrowed under the Blocked Term Loan (as defined elsewhere herein) and which became available to us for the purpose of consummating the Cristal Transaction. Allocation of the Purchase Price For the Cristal Transaction, we have applied the acquisition method of accounting in accordance with ASC 805, "Business Combinations", with respect to the identifiable assets and liabilities of Cristal, which have been measured at estimated fair value as of the date of the business combination. The aggregate purchase price noted above was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values at the acquisition date, primarily using Level 2 and Level 3 inputs (see Note 15 for an explanation of Level 2 and Level 3 inputs). These fair value estimates represent management’s best estimate of future cash flows (including sales, cost of sales, income taxes, etc.), discount rates, competitive trends, market comparables and other factors. Inputs used were generally determined from historical data supplemented by current and anticipated market conditions and growth rates. During the first quarter of 2020, we finalized the purchase price allocation which resulted in increasing environmental liabilities by $8 million, increasing property, plant and equipment by $13 million, decreasing noncontrolling interest by $3 million, decreasing deferred taxes by $6 million, increasing liabilities held for sale by $5 million and decreasing inventory by $4 million, as well as other minor adjustments. The adjustments to the unaudited Condensed Consolidated Statement of Operations that would have been recognized in the second quarter of 2019 if the measurement period adjustments had been completed as of the acquisition date would have increased the net loss by approximately $1 million. The final purchase price consideration and estimated fair value of Cristal's net assets acquired on April 10, 2019 are shown below. The assets and liabilities of Cristal's North American TiO 2 business, that was subsequently divested on May 1, 2019, are shown as held for sale in the fair value of assets acquired and liabilities assumed. Fair Value Purchase Price Consideration: Tronox Holdings plc shares issued 37,580,000 Tronox Holdings plc closing price per share on April 10, 2019 $ 14.00 Total fair value of Tronox Holdings plc shares issued at acquisition date $ 526 Cash consideration paid $ 1,675 Total purchase price $ 2,201 Fair Value Fair Value of Assets Acquired: Accounts receivable $ 251 Inventory 689 Deferred tax assets 51 Prepaid and other assets 81 Property, plant and equipment 759 Mineral leaseholds 95 Intangible assets 64 Lease right of use assets 40 Other long-term assets 43 Assets held for sale 850 Total assets acquired $ 2,923 Less: Liabilities Assumed Accounts payable $ 102 Accrued liabilities 137 Short-term lease liabilities 13 Deferred tax liabilities 2 Pension and postretirement healthcare benefits 76 Environmental liabilities 72 Asset retirement obligations 75 Long-term debt 22 Long-term lease liabilities 24 Other long-term liabilities 20 Liabilities held for sale 131 Total liabilities assumed $ 674 Less noncontrolling interest 48 Purchase price $ 2,201 Summary of Significant Fair Value Methods The methods used to determine the fair value of significant identifiable assets and liabilities included in the allocation of purchase price are included in Note 3 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Supplemental Pro forma financial information The following unaudited pro forma information gives effect to the Cristal Transaction as if it had occurred on January 1, 2018. The unaudited pro forma financial information reflects certain adjustments related to the acquisition, such as: (1) conforming the accounting policies of Cristal to those applied by Tronox; (2) conversion to U.S. GAAP from IFRS for Cristal; (3) the elimination of transactions between Tronox and Cristal; (4) recording certain incremental expenses resulting from purchase accounting adjustments, such as inventory step-up amortization, depreciation, depletion and amortization expense in connection with fair value adjustments to property, plant and equipment, mineral leases and intangible assets; (5) recording the contract loss on the sale of the 8120 product line as a charge in the first quarter of 2018; (6) recording all transaction costs incurred in the first quarter of 2018; (7) recording the effect on interest expense related to borrowings in connection with the Cristal Transaction; and (8) recording the related tax effects and the impacts to EPS for the shares issued in conjunction with the transaction. The unaudited pro forma financial information should not be relied upon as being indicative of the historical results that would have been obtained if the Cristal Transaction had actually occurred on that date, nor the results of operations in the future. In accordance with ASC 805, the supplemental pro forma results of operations for the three and nine months ended September 30, 2019, which were updated subsequently to reflect final purchase price allocation adjustments, are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2019 Net sales $ 768 $ 2,315 Net income from continuing operations attributable to Tronox Holdings plc $ 19 $ 22

Restructuring and Related Activities [Abstract]
Restructuring Initiatives	Restructuring Initiatives In April 2019, we announced the completion of the Cristal Transaction. During the second quarter of 2019, as a result of the acquisition, we outlined a broad based synergy savings program that is expected to reduce costs, simplify processes and focus the organization’s structure and resources on key growth initiatives. During the three and nine months ended September 30, 2020, we recorded costs of $1 million and $3 million, respectively, in our unaudited Condensed Consolidated Statement of Operations. For both the three and nine months ended September 30, 2019, we recorded costs of $3 million and $13 million, respectively, in our unaudited Condensed Consolidated Statement of Operations. The costs consisted primarily of charges for employee related costs, including severance. The liability balance for restructuring as of September 30, 2020, is as follows: Employee- Balance, December 31, 2019 $ 10 First Quarter 2020 charges 2 Cash payments (4) Foreign exchange and other 1 Balance, March 31, 2020 $ 9 Second Quarter 2020 charges — Cash payments (5) Foreign exchange and other — Balance, June 30, 2020 $ 4 Third Quarter 2020 charges $ 1 Cash payments $ (2) Foreign exchange and other $ — Balance, September 30, 2020 $ 3

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We recognize revenue at a point in time when the customer obtains control of the promised products. For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to the customer at a specified destination or time. Contract assets represent our rights to consideration in exchange for products that have transferred to a customer when the right is conditional on situations other than the passage of time. For products that we have transferred to our customers, our rights to the consideration are typically unconditional and only the passage of time is required before payments become due. These unconditional rights are recorded as accounts receivable. As of September 30, 2020, and December 31, 2019, we did not have material contract asset balances. Contract liabilities represent our obligations to transfer products to a customer for which we have received consideration from the customer. Infrequently we may receive advance payment from our customers that is accounted for as deferred revenue. Deferred revenue is earned when control of the product transfers to the customer, which is typically within a short period of time from when we received the advanced payment. Contract liability balances as of September 30, 2020 and December 31, 2019 were approximately $3 million and $1 million, respectively. Contract liability balances were reported as “Accounts payable” in the unaudited Condensed Consolidated Balance Sheets. All contract liabilities as of December 31, 2019 were recognized as revenue in “Net sales” in the unaudited Condensed Consolidated Statements of Operations during the first quarter of 2020. Disaggregation of Revenue We operate under one operating and reportable segment, TiO 2 . We disaggregate our revenue from contracts with customers by product type and geographic area. We believe this level of disaggregation appropriately depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors and reflects how our business is managed. Net sales to external customers by geographic areas where our customers are located were as follows: Three Months Ended Nine Months Ended 2020 2019 2020 2019 North America $ 189 $ 203 $ 521 $ 521 South and Central America 51 52 113 113 Europe, Middle-East and Africa 244 266 736 712 Asia Pacific 191 247 605 603 Total net sales $ 675 $ 768 $ 1,975 $ 1,949 Net sales from external customers for each similar type of product were as follows: Three Months Ended Nine Months Ended 2020 2019 2020 2019 TiO 2 $ 543 $ 603 $ 1,589 $ 1,505 Zircon 56 68 189 220 Feedstock and other products 76 97 197 224 Total net sales $ 675 $ 768 $ 1,975 $ 1,949 Feedstock and other products mainly include rutile prime, ilmenite, chloride (“CP”) slag, pig iron and other mining products. During the nine months ended September 30, 2020 and 2019, our ten largest third-party TiO 2 customers represented 33% and 32%, respectively, of our consolidated net sales. During the nine months ended September 30, 2020 and 2019, no single customer accounted for 10% of our consolidated net sales.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our operations are conducted through various subsidiaries in a number of countries throughout the world. We have provided for income taxes based upon the tax laws and rates in the countries in which operations are conducted and income is earned. Income (loss) from continuing operations before income taxes is comprised of the following: Three Months Ended Nine Months Ended 2020 2019 2020 2019 Income tax (provision) benefit $ 893 $ (12) $ 876 $ (10) Income (loss) from continuing operations before income taxes $ 9 $ — $ 62 $ (87) Effective tax rate (9,922) % N/A (1,413) % (11) % Tronox Holdings plc, a U.K. public limited company, became the public parent during the three months ended March 31, 2019. Prior to the three months ended March 31, 2019, Tronox Limited was the public parent, registered under the laws of the State of Western Australia but managed and controlled in the U.K. The statutory tax rate in the U.K. at both September 30, 2020 and 2019 was 19%. The large negative effective tax rates for both the three and nine months ended September 30, 2020 are caused by the release of a $895 million valuation allowance in the U.S. All periods in 2020 and 2019 are additionally influenced by a variety of factors, primarily income and losses in jurisdictions with full valuation allowances, disallowable expenditures, restructuring impacts, and our jurisdictional mix of income at tax rates different than the U.K. statutory rate. At each reporting date, we perform an analysis to determine the likelihood of realizing our deferred tax assets and whether a valuation allowance is required or sufficient evidence exists to support the reversal of all or a portion of a valuation allowance. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. Our analysis takes into consideration all available positive and negative evidence, including prior operating results, the nature and reason for any losses, our forecast of future taxable income, utilization of tax planning strategies, and the dates on which any deferred tax assets are expected to expire. These assumptions and estimates require a significant amount of judgment and are made based on current and projected circumstances and conditions. During the three months ended September 30, 2020, we determined sufficient positive evidence existed to reverse a portion of the valuation allowance attributable to the deferred tax assets associated with our operations in the U.S. This reversal resulted in a non-cash deferred tax benefit of $895 million. Our analysis considered all positive and negative evidence, including (i) three years of cumulative income for our U.S. subsidiaries, (ii) our continuing and improved profitability over the last twelve months in this jurisdiction, (iii) estimates of continued profitability based on updates to our latest forecasts, (iv) changes in the factors that drove losses in the past, primarily interest expenses incurred in the U.S, and (v) risk that certain deferred tax assets may be subject to limitation under IRC Section 382. Based on this analysis, we concluded that it was more likely than not that our U.S. subsidiaries will be able to utilize all of their deferred tax assets with an indefinite life. A portion of the U.S. deferred tax assets are attributable to net operating losses (NOLs) incurred in prior years which are subject to expiration in future years. Our analysis did not support that these limited-life NOLs would be utilized before their expiration, and it is against these deferred tax assets in the U.S. that the Company continues to carry a valuation allowance with a current estimated value of $1,067 million. We continue to maintain full valuation allowances related to the total net deferred tax assets in Australia, Belgium, Brazil, and Switzerland, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. It is reasonably possible that a portion of these valuation allowances could be reversed within the next year due to increased profitability levels. Until these valuation allowances are eliminated, future provisions for income taxes for these jurisdictions will include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments. Additionally, we have valuation allowances against specific tax assets in the Netherlands, South Africa, the U.K., and the U.S. We currently have no uncertain tax positions recorded; however, we continue to evaluate the companies acquired in the Cristal Transaction, and it is reasonably possible that this could change in the next 12 months. The Company was advised that the Australian Taxation Office has commenced a tax audit for certain fiscal periods prior to the closing of the Cristal Transaction and extending through 2019. The ultimate outcome of such an audit is not presently known. Cristal is obligated to indemnify us for pre-closing tax liabilities on any assessment associated with this audit. We believe that we have made adequate provision for income taxes that may be payable with respect to years open for examination; however, the ultimate outcome is not presently known and, accordingly, adjustments to our provisions may be necessary and/or reclassifications of noncurrent tax liabilities to current may occur in the future.

Average effective interest rate on the Standard Bank Term Loan Facility of 8.2% and 10.0% during the nine months ended September 30, 2020 and 2019, respectively. (2) The Standard Bank Term Loan Facility contains financial covenants relating to certain ratio tests. (3) On May 1, 2020, Tronox Incorporated, a wholly-owned indirect subsidiary of the Company, issued 6.5% senior secured notes due 2025 for an aggregate principal amount of $500 million (the "6.5% Senior Secured Notes due 2025"), which were issued under an indenture dated May 1, 2020. A portion of the proceeds of this debt offering was utilized to repay the $200 million of the Company's outstanding borrowings under its Wells Fargo, Standard Bank, and Emirates revolvers which was originally borrowed during the first quarter of 2020. (4) The Term Loan Facility consists of (i) a U.S. dollar term facility in an aggregate principal amount of $1.5 billion (the “Term Loans”) with our subsidiary, Tronox Finance LLC (“Tronox Finance”) as the borrower and (ii) a U.S. dollar term facility in an aggregate principal amount of $650 million (the “Blocked Term Loan”) with our unrestricted subsidiary, Tronox Blocked Borrower LLC (the “Blocked Borrower”) as the borrower, which Blocked Term Loan was funded into a blocked account. Upon consummation of the Cristal Transaction on April 10, 2019, the Blocked Borrower merged with and into Tronox Finance, and the Blocked Term Loan became available to Tronox Finance. Short-Term Debt Short-term debt and available facilities consisted of the following: Annual Interest Rate Maturity Date September 30, 2020 December 31, 2019 Wells Fargo Revolver (1) Variable 9/22/2022 $ — $ — Standard Bank Revolver (2) Variable 3/25/2022 — — Emirates Revolver (3) Variable 3/31/2021 — — SABB Credit Facility (3) Variable 12/13/2020 6 — Short-term debt (4) $ 6 $ — _______________ (1) In March 2019, the Wells Fargo Revolver was amended, which amongst other things, modified certain components of the borrowing base in order to increase the potential availability of credit. We also voluntarily reduced the revolving credit lines under the Wells Fargo Revolver from $550 million to $350 million. As a result of this modification, we accelerated the recognition of a portion of the deferred financing costs related to the Wells Fargo Revolver and during the nine months ended September 30, 2019, recorded a charge of $2 million in “Loss on extinguishment of debt” within the unaudited Condensed Consolidated Statement of Operations. No charges were recorded during the three months ended September 30, 2019. At September 30, 2020, there were $30 million of issued and undrawn letters of credit under the Wells Fargo Revolver. The Wells Fargo Revolver contains a springing financial covenant that requires the Company and its restricted subsidiaries to maintain a consolidated fixed charge coverage ratio of at least 1.0:1.0 during certain test periods based on borrowing availability under the Wells Fargo Revolver or following the occurrence of specified events of default. (2) In connection with the Standard Bank Credit Facility ("Standard Bank Revolver") entered into on March 25, 2019, the ABSA Revolving Credit Facility ("ABSA Revolver") was terminated on March 26, 2019. As a result of the termination, we accelerated the recognition of the remaining deferred financing costs related to the ABSA Revolver during the nine months ended September 30, 2019 and recorded less than $1 million in “Loss on extinguishment of debt” within the unaudited Condensed Consolidated Statement of Operations. No charges were recorded during the three months ended September 30, 2019. (3) In March 2020, the Company entered into an amendment to, amongst other things, extend the maturity date of the Emirates Revolver from March 31, 2020 to March 31, 2021. In October 2020, the Company extended the maturity date of the SABB Credit Facility from November 30, 2020 to December 13, 2020. (4) In March 2020, under an abundance of caution given the uncertainty associated with the Covid-19 pandemic, the Company drew down $200 million of borrowings under its Wells Fargo, Standard Bank, and Emirates revolvers in order to increase liquidity and preserve financial flexibility which was repaid in May 2020 with a portion of the proceeds of the 6.5% Senior Secured Notes due 2025. Additionally, during the nine months ended September 30, 2020, our KSA subsidiary drew down $13 million on its SABB Credit Facility for local working capital purposes. During the three months ended September 30, 2020, the Company repaid $7 million on the SABB Credit Facility. As a result, at September 30, 2020, the short-term debt balance was $6 million based on the September 30, 2020 exchange rate. There were no comparable amounts outstanding as of December 31, 2019. Debt Covenants At September 30, 2020, we are in compliance with all financial covenants in our debt facilities.

The agreements expire in September 2024. The Company’s objectives in using the interest-rate swap agreements are to add stability to interest expense and to manage its exposure to interest rate movements. These interest rate swaps have been designated as cash flow hedges and involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Fair value gains or losses on these cash flow hedges are recorded in other comprehensive (loss) income and are subsequently reclassified into interest expense in the same periods during which the hedged transactions affect earnings. At September 30, 2020 and December 31, 2019, the net unrealized loss of $61 million and $22 million, respectively, was recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet. For the three and nine months ended September 30, 2020, the amounts recorded in interest expense related to the interest-rate swap agreements were $4 million and $6 million, respectively. For the three and nine months ended September 30, 2019, the net amounts recorded in interest expense related to the interest-rate swap agreements were both less than $1 million of interest income and interest expense, respectively. Foreign Currency Risk During the third quarter of 2019 and the first quarter of 2020, we entered into foreign currency contracts used to hedge forecasted third party non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold for our Australian subsidiaries. These foreign currency contracts are designated as cash flow hedges. Changes to the fair value of these foreign currency contracts are recorded as a component of other comprehensive (loss) income, if these contracts remain highly effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or are recognized in other income (expense) when the transactions are no longer probable of occurring. As of September 30, 2020, we had notional amounts of (i) 635 million South African Rand (or approximately $38 million at September 30, 2020 exchange rate) that expire between December 30, 2020 and February 25, 2021 to reduce the exposure of our South African subsidiaries’ third party sales to fluctuations in currency rates, and (ii) $410 million Australian dollars (or approximately $294 million at September 30, 2020 exchange rate) that expire between December 30, 2020 and December 30, 2021 to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates. At September 30, 2020 and December 31, 2019, there was an unrealized net gain of $42 million and an unrealized net gain of $30 million, respectively, recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet, of which $32 million is expected to be recognized in earnings over the next twelve months.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standards also have established a fair value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value into three broad levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities Level 2 -Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly Level 3 -Unobservable inputs based on the Company’s own assumptions Our debt is recorded at historical amounts. The following table presents the fair value of our debt and derivative contracts at both September 30, 2020 and December 31, 2019: September 30, December 31, Term Loan Facility $ 1,788 $ 1,820 Standard Bank Term Loan Facility 109 158 Senior Notes due 2025 445 459 Senior Notes due 2026 616 636 6.5% Senior Secured Notes due 2025 523 — Tikon Loan 16 16 Australian Government Loan 1 1 Interest rate swaps 61 22 Foreign currency contracts, net 43 37 We determined the fair value of the Term Loan Facility, the Senior Notes due 2025, the Senior Notes due 2026 and 6.5% Senior Secured Notes due 2025 using quoted market prices, which under the fair value hierarchy is a Level 1 input. We determined the fair value of the Standard Bank Term Loan Facility and Tikon Loan utilizing transactions in the listed markets for identical or similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan is based on the contracted amount which is a Level 2 input. We determined the fair value of the foreign currency contracts and the interest rate swaps using inputs other than quoted prices in active markets that are observable either directly or indirectly. The fair value hierarchy for the foreign currency contracts and interest rate swaps is a Level 2 input.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Capital Commitments — Includes obligations for purchase requirements of process chemicals, supplies, utilities and services entered into in the ordinary course of business. At September 30, 2020, purchase commitments were $73 million for 2020, $98 million for 2021, $73 million for 2022, $57 million for 2023, $52 million for 2024, and $179 million thereafter. Letters of Credit —At September 30, 2020, we had outstanding letters of credit and bank guarantees of $73 million, of which $32 million were letters of credit and $41 million were bank guarantees. Amounts for performance bonds were not material. Environmental Matters — It is our policy to record appropriate liabilities for environmental matters when remedial efforts are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flows. The timing of cash expenditures depends principally on the timing of remedial investigations and feasibility studies, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties. Included in these environmental matters are the following: Hawkins Point Plant. Residual waste mud, known as Batch Attack Mud, and a spent sulfuric waste stream were deposited in an onsite repository (the “Batch Attack Lagoon”) at a former TiO 2 manufacturing site, Hawkins Point Plant in Baltimore, Maryland, operated by Cristal USA, Inc. from 1954 until 2011. We assumed responsibility for remediation of the Hawkins Point Plant when we acquired the TiO 2 business of Cristal in April 2019. In 1984, a predecessor of Cristal and the Maryland Department of the Environment (“MDE”) entered into a consent decree (the “Consent Decree”) to address the Batch Attack Lagoon. The Consent Decree required that Cristal close the Batch Attack Lagoon when the Hawkins Point Plant ceased operations. In addition, we are investigating whether hazardous substances are migrating from the Batch Attack Lagoon. A provision of $60 million has been made in our financial statements for the Hawkins Point Plant consistent with the accounting policy described above. We are in discussions with the MDE regarding a new consent decree to address both the Batch Attack Lagoon as well as other environmental contamination issues associated with the Hawkins Point Plant. Other Matters — We are subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of our business, including matters relating to commercial transactions, prior acquisitions and divestitures, including our acquisition of Cristal, employee benefit plans, intellectual property, and environmental, health and safety matters. We recognize a liability for any contingency that is probable of occurrence and reasonably estimable. We continually assess the likelihood of adverse judgments of outcomes in these matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Included in these other matters is the following: Venator Materials plc v. Tronox Limited. In May 2019, Venator Materials plc (“Venator”) filed an action in the Superior Court of the State of Delaware alleging among other things that we owed Venator a $75 million “Break Fee” pursuant to the terms of a preliminary agreement dated July 14, 2018 (the “Exclusivity Agreement”). The Exclusivity Agreement required, among other things, Tronox and Venator to use their respective best efforts to negotiate a definitive agreement to sell the entirety of the National Titanium Dioxide Company Limited’s (“Cristal’s”) North American operations to Venator if a divestiture of all or a substantial part of these operations were required to secure the approval of the Federal Trade Commission for us to complete our acquisition of Cristal’s TiO 2 business. In June 2019, we denied Ventaor's claims and counterclaimed against Venator seeking to recover $400 million in damages from Venator that we suffered as a result of Venator’s breaches of the Exclusivity Agreement. Specifically, we alleged, among other things, that Venator’s failure to use best efforts constituted a material breach of the Exclusivity Agreement and directly resulted in and caused us to sell Cristal’s North American operations to an alternative buyer for $701 million, $400 million less than the price Venator had agreed to in the Exclusivity Agreement. Though we believe that our interpretation of the Exclusivity Agreement is correct, there can be no assurance that we will prevail in litigation.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Tronox Holdings plc Amended and Restated Management Equity Incentive Plan On March 27, 2019, in connection with the re-domicile transaction, Tronox Holdings plc assumed the management equity incentive plan previously adopted by Tronox Limited, which plan was renamed the Tronox Holdings plc Amended and Restated Management Equity Incentive Plan ("MEIP"). The amendments to the plan were made to provide, among other things, for the appropriate substitution of Tronox Holdings in place of Tronox Limited and to ensure the compliance with the laws of England and Wales law in place of Australian law. The MEIP permits the grant of awards that are comprised of incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards, and other share-based awards, cash payments, and other forms as the compensation committee of the Board of Directors (the “Board”) in its discretion deems appropriate, including any combination of the above. Subject to further adjustment, as of December 31, 2019, the maximum number of shares which may be subject to awards (inclusive of incentive options) is 20,781,225 ordinary shares. The maximum number of shares which may be subject to awards under our MEIP was increased by 8,000,000 on the affirmative vote of our shareholders on June 24, 2020. Restricted Share Units (“RSUs”) 2020 Grant - During the nine months ended September 30, 2020, the Company granted both time-based and performance-based awards to certain members of management and to members of the Board. A total of 1,603,208 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2023. A total of 183,374 of time-based awards were granted to members of the Board of which 21,654 vested in June 2020 and 161,720 will vest in May 2021. A total of 1,512,788 of performance-based awards were granted, of which 756,394 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 756,394 of the awards vest based on certain performance metrics of the Company. The non-TSR performance-based awards vest on March 5, 2023 based on the achievement against the target average company performance of three separate performance periods, commencing on January 1 of each 2020, 2021, and 2022 and ending on December 31 of each 2020, 2021 and 2022, for which, for each performance period, the performance metric is an average annual operating return on net assets (ORONA). Similar to the Company's historical TSR awards granted in prior years, the TSR awards vest based on the Company's three-year TSR versus the peer group performance levels. Given these terms, the TSR metric is considered a market condition for which we used a Monte Carlo simulation to determine the weighted average grant date fair value of $10.01. The following weighted average assumptions were utilized to value the TSR grants: 2020 Dividend yield 2.13 % Expected historical volatility 58.30 % Risk free interest rate 1.42 % Expected life (in years) 3 The unrecognized compensation cost associated with all unvested awards at September 30, 2020 was $39 million, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of approximately 1.8 years. During the three and nine months ended September 30, 2020, we recorded $8 million and $19 million of stock compensation expense, respectively. The stock compensation expense for the nine months ended September 30, 2020 is inclusive of a $6 million credit for the reversal of expense due to the 2018 performance grants. During the three and nine months ended September 30, 2019, we recorded $9 million and $24 million of stock compensation expense respectively.

During the nine months ended September 30, 2020, the Company made contributions to its pension plans of approximately $22 million. The Company expects to make an additional $3 million to $5 million of pension contributions for the remainder of 2020. During the three months ended September 30, 2020, we received approximately $5 million as a final settlement of our Australian defined benefit plan which was recorded against the pension plan asset within "Other long-term assets" on the Condensed Consolidated Balance Sheet. For the both the three months and nine months ended September 30, 2020 and 2019, we contributed $1 million and $3 million, respectively, to the Netherlands Multiemployer Plan, which was primarily recognized in “Cost of goods sold” in the unaudited Condensed Consolidated Statement of Operations.

Related Party Transactions [Abstract]
Related Parties	Related Parties Exxaro On November 26, 2018, we, certain of our subsidiaries and Exxaro entered into the Completion Agreement. The Completion Agreement provides for the orderly sale of Exxaro’s remaining ownership interest in us, subject to market conditions, helped to facilitate the re-domicile transaction, as well as addressed several legacy issues related to our 2012 acquisition of Exxaro’s mineral sands business. Pursuant to the terms of the Completion Agreement, on May 9, 2019, Exxaro exercised their right under the agreement to sell 14 million shares to us for an aggregate purchase price of approximately $200 million or $14.319 per share, plus fees of approximately $1 million. The share price was based upon a 5% discount to the 10 day volume weighted average price as of the day that Exxaro exercised their sale notice to us. Upon repurchase of the shares by the Company, the shares were cancelled. As a result of the sale of the 14 million shares on May 9, 2019, we recorded a liability of $4 million which was included in “Accrued liabilities” in our Consolidated Balance Sheets as of December 31, 2019 and was subsequently paid in January 2020. Futhermore, pursuant to the Completion Agreement, the parties agreed to accelerate our purchase of Exxaro's 26% membership interest in Tronox Sands LLP, a U.K. limited liability partnership ("Tronox Sands"). On February 15, 2019, we completed the redemption of Exxaro's ownership interest in Tronox Sands for consideration of approximately ZAR 2.06 billion (or approximately $148 million in cash), which represented Exxaro's indirect share of the loan accounts in our South African subsidiaries. At September 30, 2020, Exxaro continues to own approximately 14.7 million shares of Tronox, or a 10.3% ownership interest, as well as their 26% ownership interest in our South African operating subsidiaries. At the present time, we are unable to reasonably determine when and if Exxaro will sell its remaining shares in the foreseeable future. Tasnee/Cristal On April 10, 2019, we announced the completion of the acquisition of the TiO 2 business of Cristal for $1.675 billion of cash, subject to a working capital and noncurrent liability adjustment, plus 37,580,000 ordinary shares. At September 30, 2020, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a wholly-owned subsidiary of Tasnee, continues to own 37,580,000 shares of Tronox, or a 26% ownership interest. In February 2020, Tronox and Cristal resolved the working capital and noncurrent liability adjustment by agreeing that no payment was required by either party. On May 9, 2018, we entered into an Option Agreement with AMIC which is owned equally by Tasnee and Cristal. Under the terms of the Option Agreement, AMIC granted us an option (the “Option”) to acquire 90% of a special purpose vehicle (the “SPV”), to which AMIC’s ownership in a titanium slag smelter facility (the “Slagger”) in The Jazan City for Primary and Downstream Industries in KSA will be contributed together with $322 million of AMIC indebtedness (the “AMIC Debt”). The Option may be exercised if the Slagger achieves certain production criteria related to sustained quality and tonnage of slag produced (the “Option Criteria”). Likewise, AMIC may require us to acquire the Slagger on the same terms if the Option Criteria are satisfied. Furthermore, pursuant to the Option Agreement and during its term, we agreed to lend AMIC and, upon the creation of the SPV, the SPV up to $125 million for capital expenditures and operational expenses intended to facilitate the start-up of the Slagger (the “Tronox Loans”). Such funds may be drawn down by AMIC and the SPV, as the case may be, on a quarterly basis as needed based on a budget reflecting the anticipated needs of the Slagger start-up. For the three and nine months ended September 30, 2020, we have loaned an additional $12 million and $24 million respectively for capital expenditures and operational expenses to facilitate the startup of the Slagger. We have recorded $113 million of total principal loan payments and related interest of $5 million within “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheet at September 30, 2020. The Option did not have a significant impact on the financial statements as of or for the periods ended September 30, 2020. Subsequent to the period ended September 30, 2020, on October 8, 2020, we loaned AMIC an additional amount of approximately $12 million which brought the total amount that we have lent under the Tronox Loans equal to the $125 million maximum amount that we agreed to lend. On May 13, 2020, we amended the Option Agreement (the "First Amendment") with AMIC to address circumstances in which the Option Criteria cannot be satisfied. Pursuant to the First Amendment, Tronox has the right to acquire the SPV in exchange for its forgiveness of the Tronox Loan, up to $125 million of principal amount and any interest accrued thereon of the Tronox Loans plus or minus 90% of the SPV’s net working capital. The First Amendment did not have a significant impact on our financial statements as of or for the period ended September 30, 2020. Additionally, on May 13, 2020, we amended a Technical Services Agreement that we had entered with AMIC on March 15, 2018, to add project management support services. Under this arrangement, AMIC and its consultants are still responsible for engineering and construction of the Slagger while we provide technical advice and project management services including supervision and management of third party consultants intended to satisfy the Option Criteria. As compensation for these services, Tronox receives a monthly management fee of approximately $1 million, which is recorded in “Other income (expense), net” within the unaudited Condensed Consolidated Statement of Operations and in “Prepaid and other assets” on the unaudited Condensed Consolidated Balance Sheet. The monthly management fee is subject to certain success incentives if and when the Slagger achieves the Option Criteria. Tronox recorded approximately $2 million and $3 million in "Other Income" for both the three and nine months ended September 30, 2020, respectively, in the unaudited Condensed Consolidated Statement of Operations. At September 30, 2020, Tronox had a receivable due from AMIC related to management fee of $1 million that is recorded within “Prepaid and other assets”. In conjunction with closing of the Cristal Transaction on April 10, 2019, we entered into a transition services agreement with Tasnee, Cristal and AMIC. Under the terms of the transition services agreement, Tasnee and its affiliates will provide services to Tronox related to information technology support and infrastructure, logistics, safety, health and environmental, treasury and tax. Similarly, Tronox will provide services to Tasnee and its affiliates for information technology support and infrastructure, finance and accounting, tax, treasury, human resources, logistics, research and development and business development. As part of the transition services agreement, Tronox recorded a net reduction of $1 million in “Selling, general and administrative expenses” for both the three and nine months ended September 30, 2020, respectively, in the unaudited Condensed Consolidated Statement of Operations. The net reduction of selling, general and administrative expenses associated with the transition services agreement generally represents a recovery of the related costs. At September 30, 2020, Tronox had a receivable due from Tasnee of $13 million and a payable due to Tasnee of $3 million that are recorded within “Prepaid and other assets” and “Accrued liabilities”, respectively, on the unaudited Condensed Consolidated Balance Sheet. The balance in prepaid and other assets relate primarily to amounts arising from transition service agreements, stamp duty taxes paid on behalf of Tasnee and pre-acquisition activities. Balances in accrued liabilities relate to pre-acquisition activity and those balances are expected to be settled in the near term. On December 29, 2019, we entered into an agreement with Cristal to acquire certain assets co-located at our Yanbu facility which produces metal grade TiCl 4 ("MGT"). Consideration for the acquisition is the assumption by Tronox of a $36 million note payable to Cristal. The MGT is used at a titanium "sponge" plant facility, 65% of the ownership interests of which are held by Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd ("ATTM"), a joint venture between AMIC and Toho Titanium Company Ltd. ATTM uses the TiCl 4 , which we supply by pipeline, for the production of titanium sponge, a precursor material used in the production of titanium metal. We currently operate the MGT asset for AMIC under an interim arrangement and expect this transaction to close in 2020. As a result of the transactions we have entered into related to the MGT assets, during the three and nine months ended September 30, 2020, Tronox recorded $1 million and $4 million for purchase of chlorine gas from ATTM and such amounts are recorded in "Cost of goods sold" on the unaudited Condensed Consolidated Statement of Operations. The amount due to ATTM as of September 30, 2020 for the purchase of chlorine gas was $6 million and is recorded within “Accrued liabilities” on the unaudited Condensed Consolidated Balance Sheet. In addition, during the three and nine months ended September 30, 2020, Tronox recorded $7 million and $19 million, respectively, for MGT sales made to AMIC and such amounts were recorded in “Net sales” on the unaudited Condensed Consolidated Statement of Operations. At September 30, 2020, Tronox had a receivable from AMIC of $6 million from MGT sales that is recorded within “Prepaid and other assets” on the unaudited Condensed Consolidated Balance Sheet.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2019. The acquisition of Cristal has impacted the comparability of our financial statements. As the Cristal Transaction was completed on April 10, 2019, in accordance with ASC 805, the nine month period ended September 30, 2019 includes the results of the Cristal business since the date of the acquisition, while both the three month periods ended September 30, 2020 and September 30, 2019 and the nine month period ended September 30, 2020 include the results of the combined business. 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 September 30, 2020, and its results of operations for the three and nine months ended September 30, 2020 and 2019. 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 any potential impacts on the economy as a result of the Covid-19 pandemic which could impact revenue growth and collectibility of trade receivables.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements 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. The standard modifies the disclosure requirements in Topic 820, Fair Value Measurement, by: removing certain disclosure requirements related to the fair value hierarchy; modifying existing disclosure requirements related to measurement uncertainty; and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019, with early adoption permitted. We adopted this standard on January 1, 2020 and it did not have a material impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), as amended. The standard introduces a new accounting model for expected credit losses on financial instruments, including trade receivables, based on estimates of current expected credit losses (CECL). This standard became effective on January 1, 2020, and had an immaterial impact on the Company's consolidated financial statements as our historical bad debt expense has not been material. Recently Issued Accounting Pronouncements
Fair Value	Fair Value Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standards also have established a fair value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value into three broad levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities Level 2 -Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly Level 3 -Unobservable inputs based on the Company’s own assumptions

(4) The Term Loan Facility consists of (i) a U.S. dollar term facility in an aggregate principal amount of $1.5 billion (the “Term Loans”) with our subsidiary, Tronox Finance LLC (“Tronox Finance”) as the borrower and (ii) a U.S. dollar term facility in an aggregate principal amount of $650 million (the “Blocked Term Loan”) with our unrestricted subsidiary, Tronox Blocked Borrower LLC (the “Blocked Borrower”) as the borrower, which Blocked Term Loan was funded into a blocked account. Upon consummation of the Cristal Transaction on April 10, 2019, the Blocked Borrower merged with and into Tronox Finance, and the Blocked Term Loan became available to Tronox Finance.
Schedule of Short-term Debt and Available Facilities	Short-term debt and available facilities consisted of the following: Annual Interest Rate Maturity Date September 30, 2020 December 31, 2019 Wells Fargo Revolver (1) Variable 9/22/2022 $ — $ — Standard Bank Revolver (2) Variable 3/25/2022 — — Emirates Revolver (3) Variable 3/31/2021 — — SABB Credit Facility (3) Variable 12/13/2020 6 — Short-term debt (4) $ 6 $ — _______________ (1) In March 2019, the Wells Fargo Revolver was amended, which amongst other things, modified certain components of the borrowing base in order to increase the potential availability of credit. We also voluntarily reduced the revolving credit lines under the Wells Fargo Revolver from $550 million to $350 million. As a result of this modification, we accelerated the recognition of a portion of the deferred financing costs related to the Wells Fargo Revolver and during the nine months ended September 30, 2019, recorded a charge of $2 million in “Loss on extinguishment of debt” within the unaudited Condensed Consolidated Statement of Operations. No charges were recorded during the three months ended September 30, 2019. At September 30, 2020, there were $30 million of issued and undrawn letters of credit under the Wells Fargo Revolver. The Wells Fargo Revolver contains a springing financial covenant that requires the Company and its restricted subsidiaries to maintain a consolidated fixed charge coverage ratio of at least 1.0:1.0 during certain test periods based on borrowing availability under the Wells Fargo Revolver or following the occurrence of specified events of default. (2) In connection with the Standard Bank Credit Facility ("Standard Bank Revolver") entered into on March 25, 2019, the ABSA Revolving Credit Facility ("ABSA Revolver") was terminated on March 26, 2019. As a result of the termination, we accelerated the recognition of the remaining deferred financing costs related to the ABSA Revolver during the nine months ended September 30, 2019 and recorded less than $1 million in “Loss on extinguishment of debt” within the unaudited Condensed Consolidated Statement of Operations. No charges were recorded during the three months ended September 30, 2019. (3) In March 2020, the Company entered into an amendment to, amongst other things, extend the maturity date of the Emirates Revolver from March 31, 2020 to March 31, 2021. In October 2020, the Company extended the maturity date of the SABB Credit Facility from November 30, 2020 to December 13, 2020. (4) In March 2020, under an abundance of caution given the uncertainty associated with the Covid-19 pandemic, the Company drew down $200 million of borrowings under its Wells Fargo, Standard Bank, and Emirates revolvers in order to increase liquidity and preserve financial flexibility which was repaid in May 2020 with a portion of the proceeds of the 6.5% Senior Secured Notes due 2025. Additionally, during the nine months ended September 30, 2020, our KSA subsidiary drew down $13 million on its SABB Credit Facility for local working capital purposes. During the three months ended September 30, 2020, the Company repaid $7 million on the SABB Credit Facility. As a result, at September 30, 2020, the short-term debt balance was $6 million based on the September 30, 2020 exchange rate. There were no comparable amounts outstanding as of December 31, 2019.
