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 and South Africa 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. Our strategy is to be vertically integrated and produce enough feedstock materials to be as self-sufficient as possible in the production of TiO 2 at our nine pigment facilities located 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, pig iron and the rare-earth bearing mineral, monazite, 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 We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements included in this Form 10-K are prepared in conformity with U.S. GAAP. Our consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period. Use of Estimates 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.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Foreign Currency The U.S. dollar is our reporting currency for our consolidated financial statements in U.S. GAAP. We determine the functional currency of each subsidiary based on a number of factors, including the predominant currency for revenues, expenditures and borrowings. Adjustments from the remeasurement of non-functional currency monetary assets and liabilities are recorded in “Other income (expense), net” in the Consolidated Statements of Operations. When a subsidiary’s functional currency is not the U.S. dollar, translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are recorded in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. Translation adjustments on intercompany foreign currency receivables and payables that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments. Revenue Recognition 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. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as “Net sales” in the Consolidated Statements of Operations. Accruals are made for sales returns, rebates and other allowances, which are recorded in “Net sales” in the Consolidated Statements of Operations and are based on our historical experience and current business conditions. Additionally, we have elected the practical expedient to exclude sales taxes and similar taxes that we collect from customers on behalf of government authorities from the revenue transaction price. See Note 3. Cost of Goods Sold Cost of goods sold includes costs for purchasing, receiving, manufacturing, and distributing products, including raw materials, energy, labor, depreciation, depletion, shipping and handling, freight, warehousing, and other production costs. Research and Development Research and development costs, included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations comprised of salaries, building costs, utilities, administrative expenses, third party research, and allocations of corporate costs, were $12 million, $12 million, and $13 million during 2023, 2022, and 2021, respectively, and were expensed as incurred. Selling, General and Administrative Expenses Selling, general and administrative expenses include costs related to marketing, research and development, agent commissions, and legal and administrative functions such as corporate management, human resources, information technology, investor relations, accounting, treasury, and tax compliance. Income Taxes We use the asset and liability method of accounting for income taxes. The estimation of the amounts of income taxes involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings, and uncertain tax positions. Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighed to determine whether a valuation allowance should be recorded. The amount of income taxes we pay is subject to ongoing audits by federal, state, and foreign tax authorities, which may result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We assess our income tax positions, and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, we record the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties are accrued as part of tax expense, where applicable. If we do not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. See Note 5. Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities; • Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and, • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities See Note 15. Cash and Cash Equivalents We consider all investments with original maturities of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are generally highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk. At both December 31, 2023 and December 31, 2022, we had restricted cash of less than $1 million which was in Australia related to outstanding performance bonds. Accounts Receivable, net of allowance for credit losses We perform credit evaluations of our customers, and take actions deemed appropriate to mitigate credit risk. Only in certain specific occasions do we require collateral in the form of bank or parent company guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions. Inventories, net Pigment inventories are stated at the lower of actual cost and net realizable value, net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method. Carrying values include material costs, labor, and associated indirect manufacturing expenses. Costs for materials and supplies, excluding titanium ore, are determined by average cost to acquire. Feedstock and co-products inventories including titanium ore are stated at the lower of the weighted-average cost of production or market. Inventory costs include those costs directly attributable to products, including all manufacturing overhead but excluding distribution costs. Raw materials are carried at actual cost. We review the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence. In either case, we record any write-down equal to the difference between the cost of inventory and its estimated net realizable value based on assumptions about alternative uses, market conditions and other factors. Inventories expected to be sold or consumed within twelve months after the balance sheet date are classified as current assets and all other inventories are classified as non-current assets. See Note 8. Long Lived Assets Property, plant and equipment, net is stated at cost less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Land improvements 10 — 20 years Buildings 10 — 40 years Machinery and equipment 3 — 25 years Furniture and fixtures 10 years Maintenance and repairs are expensed as incurred, except for costs of replacements or renewals that improve or extend the lives of existing properties, which are capitalized. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is included in “Cost of goods sold” or “Selling, general, and administrative expenses” in the Consolidated Statements of Operations. See Note 9. We capitalize costs associated with our asset retirement obligations which are generally included in machinery and equipment. See Note 17. We capitalize interest costs on major projects that require an extended period of time to complete. See Note 13. Mineral property acquisition costs are capitalized as tangible assets when management determines that probable future benefits consisting of a contribution to future cash inflows have been identified and adequate financial resources are available or are expected to be available as required to meet the terms of property acquisition and anticipated exploration and development expenditures. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs incurred to develop such property through the commencement of production are capitalized. See Note 10. Intangible assets are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated useful lives, which generally range from 3 to 20 years. See Note 11. We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined. Leases We determine if a contract is or contains a lease at inception of the contract. Our leases are primarily operating leases. Leased assets primarily include office buildings, rail cars and motor vehicles, forklifts, and other machinery and equipment. Our leases primarily have fixed lease payments, with real estate leases typically requiring additional payments for real estate taxes and occupancy-related costs. Certain of our leases also have variable lease payments. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index) are included in our initial measurement of the lease right of use assets and lease liabilities. Variable lease payments that are not index or rate based (such as variable payments based on our performance or use of the leased assets) are recorded as expenses when incurred and excluded from the measurement of right of use assets and lease liabilities. Our leases typically have initial lease terms ranging from 1 to 25 years. Some of our lease agreements include options to renew, extend or early terminate the leases. Lease term is the non-cancellable period of a lease, adjusted by the period covered by an option to extend or terminate the lease if we are reasonably certain to exercise (or not exercise) that option. Our operating leases typically do not contain purchase options we expect to exercise, residual value guarantees or other material covenants. Operating leases are recorded under “Lease right of use assets”, “Short-term lease liabilities”, and “Long-term lease liabilities” on the Consolidated Balance Sheets. Finance leases are recorded under “Property, plant and equipment net”, “Long-term debt due within one year”, and “ Long-term debt Long-term Debt Long-term debt is stated net of unamortized original issue premium or discount. Premiums or discounts are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. Deferred debt issuance costs related to a recognized debt liability are presented in the Consolidated Balance Sheets as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. See Note 13. Asset Retirement Obligations Asset retirement obligations are recorded at their estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free interest rate, which are considered Level 3 inputs. We classify accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” in the Consolidated Statements of Operations. See Note 17. Environmental Remediation and Other Contingencies We record an undiscounted liability when any of the following occur: 1) a claim or assessment has been asserted, 2) a litigation has commenced, or 3) based on available information, it is probable that a claim or an assessment will be asserted or a litigation will commence; and in addition, the outcome is expected to be unfavorable to us and the associated costs can be reasonably estimated. See Note 18. Self-Insurance We are self-insured for certain levels of general and vehicle liability, property, workers’ compensation and health care coverage. The cost of these self-insurance programs is accrued based upon estimated fully developed settlements for known and anticipated claims. Any resulting adjustments to previously recorded reserves are reflected in current operating results. We do not accrue for general or unspecific business risks. Share-based Compensation Equity Restricted Share and Restricted Share Unit Awards — The fair value of equity instruments is measured based on the share price on the grant date and is recognized over the vesting period. These awards contain service, market, and/or performance conditions. For awards containing only a service or a market condition, we have elected to recognize compensation costs using the straight-line method over the requisite service period for the entire award. For awards containing a market condition, the fair value of the award is measured using the Monte Carlo simulation under a lattice model approach. For awards containing a performance condition, the fair value is the grant date close price and compensation expense is not recognized until we conclude that it is probable that the performance condition will be met. We reassess the probability at least quarterly. See Note 20. Defined Benefit Pension and Postretirement Benefit Plans We recognize the funded status of our defined benefit pension plans and postretirement benefit plans in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. The benefit obligation for the defined benefit plans is the projected benefit obligation (PBO), which represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The benefit obligation for our postretirement benefit plans is the accumulated postretirement benefit obligation (APBO), which represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets related to our defined benefit plan represents the current market value of assets held in a trust fund, which is established for the sole benefit of plan participants. If the fair value of plan assets exceeds the benefit obligation, the plan is overfunded, and the excess is recorded as a prepaid pension asset. On the other hand, if the benefit obligation exceeds the fair value of plan assets, the plan is underfunded, and the deficit is recorded as pension and postretirement healthcare benefits obligation in the Consolidated Balance Sheet. The portion of the pension and postretirement healthcare obligations payable within the next 12 months is recorded in accrued liabilities in the Consolidated Balance Sheet. Net periodic pension and postretirement benefit cost represents the aggregation of service cost, interest cost, expected return on plan assets, amortization of prior service costs or credits and actuarial gains or losses previously recognized as a component of OCI and it is recorded in the Consolidated Statements of Operations. Net periodic cost is recorded in cost of goods sold and selling, general and administrative expenses in the Consolidated Statements of Operations based on the employees’ respective functions. Actuarial gains or losses represents the effect of remeasurement on the benefit obligation principally driven by changes in the plan actuarial assumptions. Prior service costs or credits arise from plan amendments. The actuarial gains or losses and prior service costs or credits are initially recognized as a component of Other comprehensive income (loss) in the Consolidated Statement of Comprehensive Income. Those gains or losses and prior service costs or credits are subsequently recognized as a component of net periodic cost. The measurement of benefit obligations and net periodic cost is based on estimates and assumptions approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. Defined Contribution Plans — We recognize our contribution as expense when they are due. The expense is recorded in cost of goods sold or selling, general and administrative expenses the Consolidated Statements of Operations based on the employees’ respective functions. Multiemployer Plan — We treat our multiemployer plan like a defined contribution plan. A pension plan to which two or more unrelated employers contribute is generally considered to be a multiemployer plan. As a defined contribution plan, we recognize the contribution for the period as a net benefit cost and any contributions due and unpaid as a liability.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Nature of Contracts and Performance Obligations We primarily generate revenue from selling TiO 2 pigment products and related co-products, primarily zircon and pig iron, to our customers. These products are used for the manufacture of paints, coatings, plastics, paper, and a wide range of other applications. We account for a contract with our customer when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Our promise in a contract typically relates to the transferring of a product or multiple distinct products that are substantially the same and that have the same pattern of transfer, representing a single performance obligation within a contract. We have elected to account for shipping and handling activities that occur after control of the products has transferred to the customer as contract fulfillment activities, rather than a separate performance obligation. Amounts billed to a customer in a sales transaction related to shipping and handling activities continue to be reported as “Net sales” and related costs as “Cost of goods sold” in the Consolidated Statements of Operations. The duration of our contract period is one year or less. As such, we have elected to recognize incremental costs incurred to obtain contracts, which primarily consist of commissions paid to third-party sales agents, as “Selling, general and administrative expenses” in the Consolidated Statements of Operations. Furthermore, we have elected not to disclose the value of unsatisfied performance obligations at each period end, given the original expected duration of our contracts are one year or less. Transaction Price Revenue is measured as the amount of consideration that we expect to be entitled in exchange for transferring products to the customer. The transaction price typically consists of fixed cash consideration. We also offer various incentive programs to our customers, such as rebates, discounts, and other price adjustments that represent variable consideration. We estimate variable consideration and include such consideration amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We adjust our estimate of revenue at the earlier of when the amount of consideration we expect to receive changes or when the consideration becomes fixed. Sales returns rarely happen in our business; therefore, it is unlikely that a significant reversal of revenue will occur. Sales and similar taxes we collect on behalf of governmental authorities are excluded from the transaction price for the determination of revenue. The expected costs associated with product warranties continue to be recognized as expense when the products are sold. Customer payment terms and conditions vary by contract and customer, although the timing of revenue recognition typically does not differ from the timing of invoicing. Additionally, as we generally do not grant extended payment terms, we have determined that our contracts generally do not include a significant financing component. Revenue Recognition 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 Balances 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 December 31, 2023, and December 31, 2022, 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. When a customer has poor credit worthiness, we may receive advance payment 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 both December 31, 2023 and December 31, 2022 were less than $1 million. Contract liability balances were reported as “Accrued liabilities” in the Consolidated Balance Sheets. All material contract liabilities as of December 31, 2022 and 2021 were recognized as revenue in “Net sales” in the Consolidated Statements of Operations during the first quarter of 2023 and first quarter of 2022, respectively. Disaggregation of Revenue We operate under one operating and reportable segment, Tronox. See Note 23 for details. 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: Year Ended December 31, 2023 2022 2021 North America $ 754 $ 790 $ 743 South and Central America 159 264 252 Europe, Middle-East and Africa 1,131 1,335 1,398 Asia Pacific 806 1,065 1,179 Total net sales $ 2,850 $ 3,454 $ 3,572 Net sales from external customers for each similar type of product were as follows: Year Ended December 31, 2023 2022 2021 TiO 2 $ 2,248 $ 2,693 $ 2,793 Zircon 257 438 478 Other products 345 323 301 Total net sales $ 2,850 $ 3,454 $ 3,572 Other products mainly include pig iron, TiCl 4 and other mining products. The nature, amount, timing and uncertainty of revenue and cash flows typically do not differ significantly among different products.

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) before income taxes is comprised of the following: Year Ended December 31, 2023 2022 2021 United Kingdom $ (47) $ (130) $ (16) International 96 438 390 Income before income taxes $ 49 $ 308 $ 374 The income tax (provision) benefit is summarized below: Year Ended December 31, 2023 2022 2021 United Kingdom: Current $ 1 $ — $ (1) Deferred — — — International: Current (34) (69) (55) Deferred (330) 261 (15) Income tax (provision) benefit $ (363) $ 192 $ (71) The following table reconciles the applicable statutory income tax rates to our effective income tax rates for “Income tax (provision) benefit” as reflected in the Consolidated Statements of Operations. Year Ended December 31, 2023 2022 2021 Statutory tax rate 24 % 19 % 19 % Increases (decreases) resulting from: Tax rate differences (26) 9 7 Non-taxable income and expenses 29 8 2 Valuation allowances 670 (100) (27) Corporate reorganization — — 17 Tax rate changes 10 (3) 2 State and local taxes 14 1 1 Prior year accruals 9 — (2) Branch taxation — — — Withholding taxes — 2 2 Tax credits — — (2) Expiration of net operating loss 11 2 — Other, net — — — Effective tax rate 741 % (62) % 19 % Tronox Holdings plc is a U.K. public limited company and the parent company for the business group. The statutory tax rate in the U.K. at December 31, 2023 was 25% and at December 31, 2022 and 2021 was 19%. The statutory rate in the U.K. changed to 25% effective April 1, 2023 and a weighted average rate of 23.5% was applied for the full year 2023. The effective tax rates in 2023, 2022 and 2021 are all influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, changes in tax rates, non-taxable income and expenses, prior year accruals, and rates different than the United Kingdom statutory rate. The valuation allowances in each year were impacted by items other than income and losses as follows: 2023 was impacted by recording valuation allowances in China and Australia, 2022 was impacted by releasing a valuation allowance in Australia, and 2021 was impacted by releasing a valuation allowance in Saudi Arabia. Additional factors of significance in the above table are as follows: 1) the Non-taxable income and expenses amount for 2022 includes the Venator settlement, 2) the Corporate reorganization amount for 2021 includes the liquidation of the inactive Dutch subsidiary and the write-off of its net operating losses, and 3) the Corporate reorganization amounts for 2021 include the restructuring of our Australian entities. Each of these additional factors were fully offset by valuation allowances. Net deferred tax assets (liabilities) at December 31, 2023 and 2022 were comprised of the following: December 31, 2023 2022 Deferred tax assets: Net operating loss and other carryforwards $ 1,800 $ 1,739 Property, plant and equipment, net 182 200 Reserves for environmental remediation and restoration 53 47 Obligations for pension and other employee benefits 50 46 Investments 3 4 Grantor trusts 609 621 Inventories, net 10 6 Interest 161 190 Lease liabilities 46 48 Other accrued liabilities 4 2 Foreign exchange 0 1 Other 4 5 Total deferred tax assets 2,922 2,909 Valuation allowance associated with deferred tax assets (1,860) (1,527) Net deferred tax assets 1,062 1,382 Deferred tax liabilities: Inventories, net (3) (3) Property, plant and equipment, net (223) (228) Intangible assets, net (9) (15) Lease assets (43) (38) Foreign exchange (6) (4) Interest (7) (9) Other (3) (5) Total deferred tax liabilities (294) (302) Net deferred tax asset $ 768 $ 1,080 Balance sheet classifications: Deferred tax assets — long-term $ 917 $ 1,233 Deferred tax liabilities — long-term $ (149) $ (153) Net deferred tax asset $ 768 $ 1,080 The net deferred tax assets reflected in the above table include deferred tax assets related to grantor trusts, which were established as Tronox Incorporated emerged from bankruptcy during 2011. The balances relate to the assets contributed to such grantor trusts by Tronox Incorporated and the proceeds from the resolution of previous litigation of $5.2 billion during 2014, which resulted in additional deferred tax assets of $2.0 billion. As the grantor trusts continue to spend funds received from the litigation and earn income from the investment of those funds, the U.S. net operating loss will increase or decrease. There was an increase to our valuation allowance of $333 million during 2023 and a decrease of $314 million in 2022. The table below sets forth the changes, by jurisdiction: December 31, 2023 2022 United Kingdom $ 11 $ 13 United States (18) (5) Australia 346 (314) Switzerland (7) (8) China 1 — Total increase (decrease) in valuation allowances $ 333 $ (314) During the year ended December 31, 2023, the Company identified negative evidence concerning our ability to realize the net balance of our Australia group deferred tax assets. This evidence primarily relates to losses generated during the current year and uncertainty regarding the region's ability to generate income in the near term. After weighing all the positive and negative evidence, we determined that it is more likely than not that the Australia deferred tax assets may not be realized. As a result, we recorded a $293 million non-cash charge to tax expense for the year ended December 31, 2023. The Company has a Swiss entity acquired in the Cristal transaction that had net operating loss carryovers. During the year ended December 31, 2023, a majority of these losses expired unused because the Swiss entity no longer has significant income-generating activities. A valuation allowance was previously carried against these losses and is no longer required. During the year ended December 31, 2022, the Company had determined that sufficient positive evidence existed to reverse a portion of the valuation allowance in Australia. This reversal resulted in a non-cash deferred tax benefit of $300 million. Our analysis considered all positive and negative evidence, including (i) three years of cumulative income of our Australian subsidiaries, (ii) our continuing and improved profitability over the last twelve months, (iii) estimates of continued profitability based on updated to our latest forecasts, (iv) changes in the factors that drove losses in the past, and (v) an evaluation of specific deferred tax assets for limitations under certain Australian tax provisions. Based on this analysis, we concluded that it is more likely than not that our Australian subsidiaries will be able to utilize all of their deferred tax assets except for those which are classified as Capital Gains Tax (CGT) assets. At December 31, 2023, we continue to maintain full valuation allowances related to the total net deferred tax assets in the United Kingdom, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. Future provisions for income taxes in Australia and the United Kingdom will include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments until the valuation allowances are eliminated. Additionally, we have valuation allowances against specific tax assets in China, South Africa and the U.S. These conclusions were reached by the application of ASC 740, Income Taxes , and require that all available positive and negative evidence be weighed to determine whether a valuation allowance should be recorded. The more significant evidential matter in the United Kingdom relates to cumulative book losses. The most significant evidential matter for Australia and South Africa relates to capital losses and assets that cannot be depleted or depreciated for tax purposes. The deferred tax assets generated by tax loss carryforwards in Australia, China and the United Kingdom have been fully offset by valuation allowances. In the United States, the deferred tax assets generated by tax loss carryforwards are partially offset by a valuation allowance to the extent they are subject to expiration. The expiration of these carryforwards at December 31, 2023 is shown below. The tax loss carryforwards in Australia, Saudi Arabia, France, Brazil and the United Kingdom do not expire. 2024 2025 2026 2027 2028 2029 - 2040 Unlimited Total Tax Loss Carryforwards United Kingdom $ — $ — $ — $ — $ — $ — $ (135) $ (135) Australia — — — — — — (622) (622) The Netherlands — — — — — — (122) (122) France — — — — — — (179) (179) Saudi Arabia — — — — — — (4) (4) China — — — (3) (6) — — (9) Brazil — — — — — — (11) (11) Other — — — — — — (2) (2) U.S. Federal — — — — — (3,919) (334) (4,253) U.S. State (12) (39) (66) (27) (12) (3,969) (19) (4,144) Total tax loss carryforwards $ (12) $ (39) $ (66) $ (30) $ (18) $ (7,888) $ (1,428) $ (9,481) At December 31, 2023, Tronox Holdings plc had foreign subsidiaries with undistributed earnings. Although we would not be subject to income tax on these earnings, amounts totaling $535 million are in specific jurisdictions which we assert are indefinitely reinvested outside of the parents' taxing jurisdictions. These amounts could be subject to withholding tax if distributed, but the Company has made no provision for tax related to these undistributed earnings. The Company has removed its assertion that earnings in China are indefinitely reinvested, and the withholding tax accruals for potential repatriations from that jurisdiction are now reflected in the effective tax rate reconciliation above. The noncurrent liabilities section of our Consolidated Balance Sheet does not reflect any reserves for uncertain tax positions for either 2023 or 2022. Our France returns are closed through 2020. Our Brazil, China, Netherlands, South Africa, U.K. and U.S. returns are closed through 2019. Our Australia returns are being held open back to 2017 for an on-going risk review. 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, additional provisions may be necessary and/or reclassifications of noncurrent tax liabilities to current may occur in the future. During the year ended December 31, 2023, the United Kingdom enacted legislation consistent with guidance from the Organization for Economic Co-operation and Development ("OECD") for the implementation of Pillar Two, effective in 2024. The Company does not believe this will have a significant impact on future financial results.

Accounts Receivable Securitizat

Accounts Receivable Securitization Program	12 Months Ended
	Dec. 31, 2023
Transfers and Servicing [Abstract]
Accounts Receivable Securitization Program	Accounts Receivable Securitization Program On March 15, 2022, the Company entered into an accounts receivable securitization program (“Securitization Facility”) with a financial institution ("Purchaser"), through our wholly-owned special purpose bankruptcy-remote subsidiary Tronox Securitization LLC (“ SPE”). The purpose of this program is to enhance the Company's financial flexibility by providing additional liquidity. The Securitization Facility permitted the SPE to sell accounts receivable up to $75 million (the “Facility Limit”). Under the Securitization Facility, our wholly-owned U.S. operating subsidiary, Tronox LLC (“Originator”), sells its entire accounts receivable on a periodic basis to the SPE. The SPE in turn sells undivided interests in the receivables that meet certain eligibility criteria, pursuant to the terms of a receivable purchase agreement, to the Purchaser in exchange for cash, not to exceed the Facility Limit. The SPE retains the remaining receivables as unsold receivables which are pledged as a collateral for the sold receivables to which the purchaser is granted a first priority security interest. Following the sale of the receivables by the Originator to the SPE, the receivables are legally isolated from Tronox and its affiliated entities, and upon the subsequent sale and transfer of the receivables from the SPE to the administrative agent, effective control of the receivables is passed to the purchaser, which has all rights, including the right to pledge or sell the receivables. Any new receivables that are not sold to the purchaser by the SPE are added to the unsold receivables held as collateral. In November 2022, the Securitization Facility was amended (the "First Amendment") to include receivables generated by our wholly-owned Australian operating subsidiaries, Tronox Pigment Pty Ltd., Tronox Pigment Bunbury Ltd. and Tronox Mining Australia Ltd. which increased the Facility Limit to $200 million and extended the program term to November 2025. Following this amendment, we sold additional accounts receivable in exchange for net cash proceeds of $72 million, for a total aggregate amount of $147 million for the combined program. In June 2023, the Company entered into an additional amendment (the “Second Amendment”) to further include receivables generated by our wholly-owned European operating subsidiaries Tronox Pigment Holland BV and Tronox Pigment UK Limited. Neither the facility limit nor the program term were changed as a result of the Second Amendment, which remain at $200 million and November 2025, respectively. As a result of the Second Amendment, during the year ended December 31, 2023, we incurred $1 million of transaction costs, which are recorded in "Other income (expense), net" in our Consolidated Statement of Operations. As the Company does not maintain effective control over the sold receivables, we derecognize the sold receivables from our Consolidated Balance Sheet and classify the cash proceeds as source of cash from operating activities in our Consolidated Statement of Cash Flows. The program is structured on a revolving basis under which cash collections from receivables are used to fund additional purchases of receivables at 100% face value, not to exceed the facility limit. At December 31, 2023 and 2022, the total value of accounts receivable sold under the Securitization Facility and derecognized from the Company's Consolidated Balance Sheet was $186 million and $123 million, respectively. This resulted in the Company recording $5 million and $24 million within "Accounts payable" on the Consolidated Balance Sheet at December 31, 2023 and 2022, respectively, as this amount is due to the Purchaser as a result of a periodic decrease in accounts receivable sold to the Purchaser, which was paid in January 2024 and January 2023, respectively. Additionally, at December 31, 2023 and 2022, respectively, we retained $129 million and $69 million of unsold receivables that we pledged as collateral for the sold receivables. The following table sets forth a summary of the receivables sold and fees incurred under the program during the related periods: Year Ended December 31, 2023 2022 Cash proceeds from collections reinvested in the program $ 821 $ 426 Incremental accounts receivables sold 884 549 Fees incurred 1 11 2 1 Fees due to the Purchaser relate to monthly utilization of the Securitization Facility and are recorded in "Other income (expense), net" in our Consolidated Statements of Operations.

The maturity date on the Term Loan Facility and the Cash Flow Revolver is March 11, 2028 and March 11, 2026, respectively.

Derivative Financial Instruments	Derivative Financial Instruments Derivatives recorded on the Consolidated Balance Sheet: The following table is a summary of the fair value of derivatives outstanding at December 31, 2023 and 2022: Fair Value December 31, 2023 December 31, 2022 Assets(a) Accrued Liabilities Assets(a) Accrued Liabilities Derivatives Designated as Cash Flow Hedges Interest Rate Swaps $ 18 $ — $ 30 $ — Natural Gas Hedges $ — $ 1 $ 1 $ 2 Total Hedges $ 18 $ 1 $ 31 $ 2 Derivatives Not Designated as Cash Flow Hedges Currency Contracts $ 1 $ 1 $ 1 $ — Total Derivatives $ 19 $ 2 $ 32 $ 2 (a) At December 31, 2023 and 2022, current assets of $19 million and $32 million, respectively, are recorded in prepaid and other current assets on the Consolidated Balance Sheet. Derivatives' Impact on the Consolidated Statements of Operations The following table summarizes the impact of the Company's derivatives on the Consolidated Statements of Operations: Amount of Pre-Tax Gain (Loss) Recognized in Earnings Revenue Cost of Goods Sold Other Income (Expense), net Revenue Cost of Goods Sold Other Income (Expense), net Revenue Cost of Goods Sold Other Income (Expense), net Year Ended December 31, 2023 Year Ended December 31, 2022 Year Ended December 31, 2021 Derivatives Not Designated as Hedging Instruments Currency Contracts $ — $ — $ 3 $ — $ — $ 1 $ — $ — $ 1 Derivatives Designated as Hedging Instruments Currency Contracts $ — $ (4) $ — $ 4 $ 13 $ — $ (3) $ 35 $ — Natural Gas $ — $ (5) $ — $ — $ 5 $ — $ — $ 3 $ — Total Derivatives $ — $ (9) $ 3 $ 4 $ 18 $ 1 $ (3) $ 38 $ 1 Interest Rate Risk During the second quarter of 2019, we entered into interest-rate swap agreements with an aggregate notional value of $750 million representing a portion of our Term Loan Facility, which effectively converted the variable rate to a fixed rate for that portion of the loan. The agreements were to expire in September 2024. On March 27, 2023, the Company entered into amendments to two of our existing interest rate swap agreements with the counterparty banks. As a result of these amendments, the Company terminated two of our existing interest rate swap contracts which were indexed to LIBOR with an aggregate notional value of $500 million which had maturity dates of September 2024. At the time of these amendments, the Company determined that the interest payments hedged are still probable to occur, therefore, the gains accumulated of $11 million on the interest rate swaps prior to the amendments are being amortized into interest expense through September 22, 2024, the original maturity of the interest rate swap agreements. We simultaneously entered into two SOFR-indexed forward starting interest rate swaps with the same counterparty banks with no change to the aggregate notional value. The forward starting swaps became effective in June 2023 and will mature in March 2028 which is aligned with the maturity date of the Term Loan Facility. Indexing forward starting swaps to SOFR also ensured that the reference rates in our hedge instruments are now aligned with the interest rate terms of the Term Loan Facility which also changed from LIBOR to SOFR in June 2023 in anticipation of Reference Rate Reform and pursuant to the loan agreement. We elected to apply the hedge accounting expedients in ASC Topic 848, Reference Rate Reform on Financial Reporting related to the following: 1) the assertion that the future forecasted transaction is still probable of occurring despite reference rate changes and 2) the assumption that the index of the future hedged transactions will match the index of the corresponding hedge instruments for the assessment of effectiveness. Additionally, on March 27, 2023, the Company entered into a new interest rate swap with a $200 million notional value which matures in March 2028 and effectively converts the variable rate to a fixed rate for that portion of the 2022 Term Loan Facility. On May 17, 2023, the Company entered into an agreement with the counterparty bank to amend the remaining $250 million notional of the three original interest rate swap contracts of $750 million aggregate notional value. As a result of this amendment, the Company changed the rate indexed in the contract from LIBOR to SOFR, effective June 30, 2023 in anticipation of the Reference Rate Reform and to align the index rate in this contract to that in the Term Loan Facility, as described above. This amendment did not change the notional value and the expiration date of this contract, which is set to expire in September 2024. We completed a hedge effectiveness test as a result of this amendment and determined that this hedge instrument continues to be highly effective, enabling us to continue to apply hedge accounting over the remaining term of this hedge relationship. As of December 31, 2023, the Company maintains a total of $950 million of interest rate swaps with the objective in using the interest-rate swap agreements to add stability to interest expense and to manage the Company's 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 accumulated other comprehensive loss and are subsequently reclassified into interest expense in the same periods during which the hedged transactions affect earnings. For the year ended December 31, 2023, 2022 and 2021, the amounts recorded in interest expense related to the interest-rate swap agreements were $26 million, $4 million and $16 million, respectively. At December 31, 2023 and December 31, 2022, the net unrealized gain was $18 million and the unrealized gain was $30 million, respectively, and was recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet. Foreign Currency Risk From time to time, we enter 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), net when the transactions are no longer probable of occurring. As of December 31, 2023, we had no outstanding amounts to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates or to reduce the exposure of our South African subsidiaries' third party sales to fluctuations in currency rates. At December 31, 2022, there was an unrealized net loss of $4 million recorded in "Accumulated other comprehensive loss" on the Consolidated Balance Sheet, which was fully recognized in earnings during the year ended December 31, 2023. From time to time, we enter into foreign currency contracts for the South African Rand, Australian Dollar, Euro, Pound Sterling and Saudi Riyal to reduce exposure of our subsidiaries’ balance sheet accounts not denominated in our subsidiaries’ functional currency to fluctuations in foreign currency exchange rates. Historically, we have used forward contracts to reduce the

We determined the fair value of the Standard Bank Term Loan Facility utilizing transactions in the listed markets for similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan and MGT Loan is based on the contracted amount which is a Level 2 input. We determined the fair value of the foreign currency contracts, natural gas hedges, 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, natural gas hedges, and interest rate swaps is a Level 2 input. The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term nature of these items.

Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations consist primarily of rehabilitation and restoration costs, landfill capping costs, decommissioning costs, and closure and post-closure costs. Activity related to asset retirement obligations was as follows: Year Ended December 31, 2023 2022 Balance, January 1 $ 161 $ 149 Additions 11 3 Accretion expense 15 12 Remeasurement/translation 1 (7) Changes in estimates, including cost and timing of cash flows 7 7 Settlements/payments (9) (3) Other acquisition and divestiture related — — Balance, December 31 $ 186 $ 161 December 31, 2023 2022 Asset retirement obligations were classified as follows: Current portion included in “Accrued liabilities” $ 14 $ 8 Noncurrent portion included in “Asset retirement obligations” 172 153 Asset retirement obligations $ 186 $ 161 We used the following assumptions in determining asset retirement obligations at December 31, 2023: inflation rates between 1.5% - 5.5% per year; credit adjusted risk-free interest rates between 6.0% -22.0%; the life of mines from less than 1 to 23 years and the useful life of assets between 5-44 years. Environmental Rehabilitation Scheme In accordance with applicable regulations, we established an environmental rehabilitation scheme for the prospecting and mining operations in South Africa, which receives, holds, and invests funds for the rehabilitation or management of asset retirement obligations. At December 31, 2023 and 2022, the total value of the assets held in the environmental rehabilitation scheme were $15 million and $12 million, respectively, which were recorded in “Other long-term assets” in the Consolidated Balance Sheets.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Capital Commitments —At December 31, 2023, purchase commitments were $285 million for 2024, $173 million for 2025, $167 million for 2026, $163 million for 2027, $291 million for 2028, and $1,475 million thereafter. Letters of Credit —At December 31, 2023, we had outstanding letters of credit and bank guarantees of $109 million, of which $70 million were letters of credit (inclusive of $50 million related to the sale of Hawkins Point as discussed below) and $39 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 TiO2 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 TiO2 business of Cristal in April 2019. On December 21, 2022, we sold the Hawkins Point Plant to the Maryland Port Administration ("MPA"), a state agency controlled by the Maryland Department of Transportation. Pursuant to the terms of the transaction, MPA became the lead party in developing and implementing appropriate measures to address, treat, control, and mitigate the environmental conditions at the property under the regulatory oversight of the Maryland Department of the Environment ("MPE"). Under MPA ownership, the Hawkins Point Plant will be utilized for storage and beneficial reuse of dredged material from the Port of Baltimore. In exchange for transferring ownership of the site to MPA, Tronox has agreed to make scheduled, annual payments to MPA which together with scheduled, annual contributions from MPA will be used to remediate the property. The sale of the property to MPA did not have a material impact to the Consolidated Statements of Operations. As of December 31, 2023, we have a provision of $42 million included in "Environmental liabilities" in our Consolidated Balance Sheet for the Hawkins Point Plant consistent with the accounting policy described above. 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: UK Health and Safety Matter. In April 2023, we received a summons from the UK Health and Safety Executive (HSE) alleging non-compliance with UK health and safety legislation at the Stallingborough pigment plant resulting from an incident involving a contractor in August 2021. In June 2023, Tronox Pigment UK Limited, the entity which owns the Stallingborough plant, pled guilty to the allegation. The sentencing hearing to determine monetary penalties occurred in September 2023. At such hearing, the judge imposed a monetary penalty in the amount of £207,681, inclusive of costs. We do not believe this matter will have a material adverse effect on our business, financial condition and results of operations. In addition, in February 2024, we received a second summons from the HSE alleging non-compliance with UK health and safety legislation at the Stallingborough pigment plant resulting from a separate incident involving an employee in August 2022. Based upon our current understanding, we do not believe the enforcement action with regards to this second incident will have a material adverse effect on our business, financial condition and results of operations. 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 Venator'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. On April 6, 2022, the Judge presiding over the case in the Superior Court of the State of Delaware delivered a directed verdict in favor of Venator without allowing the jury to deliberate. The Company determined not to appeal the Judge's verdict, and as such, on April 18, 2022, the Company and Venator entered into a settlement agreement whereby the Company paid $85 million, inclusive of interest, on April 25, 2022. As a result, we recorded the charge within "Venator settlement" on the Consolidated Statement of Operations for the year ended December 31, 2022. Western Australia Stamp Duty Matter. In May 2018, we lodged a pre-transaction determination request for a stamp duty exemption with the Western Australia Office of State Revenue (the “WA OSR”) in connection with our re-domicile transaction (the “Re-Domicile Transaction”). The WA OSR subsequently granted our request for an exemption in June 2018 on a preliminary basis. Immediately following the consummation of the Re-Domicile Transaction, we filed a confirmation request for the stamp duty exemption with the WA OSR. Following this confirmation request, we exchanged numerous communications with the WA OSR addressing questions raised and stating our position. In July 2021, the WA OSR informed us that they have reviewed their technical position on the applicability of the stamp duty exemption and have determined that such an exemption is disallowed. On April 8, 2022, the Company lodged an appeal of the WA OSR's decision with the Western Australia State Administrative Tribunal. On March 3, 2023, the WA OSR officially granted us the stamp duty exemption in connection with the Re-Domicile Transaction, and as such, the Tribunal proceeding was withdrawn.

Share-Based Payment Arrangement [Abstract]
Share-based Compensation	Share-based Compensation Share-based compensation expense consisted of the following: Year Ended December 31, 2023 2022 2021 Total share-based compensation expense from restricted share units $ 21 $ 26 $ 31 The stock compensation expense for the year ended December 31, 2023 is inclusive of a $4 million reduction of expense due to the 2021 performance grants. The stock compensation expense for the year ended December 31, 2021 is inclusive of a $3 million true up of expense due to the 2020 and 2021 performance grants as well as the acceleration of $2 million of stock compensation expense associated with the retirement agreement entered into with the former CEO on March 18, 2021. 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. 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. The maximum number of shares which were initially subjected to awards (inclusive of incentive options) was 20,781,225 ordinary shares and was increased by 8,000,000 on the affirmative vote of our shareholders on June 24, 2020. Restricted Share Units (“RSUs”) On an annual basis, the Company grants RSUs which have time and/or performance conditions. Both the time-based awards and the performance-based awards are classified as equity awards. 2023 Grants - The Company granted both time-based and performance-based awards to certain members of management. A total of 872,660 of time-based awards were granted to management which will vest ratably over a three-year period ending March 5, 2026. A total of 90,088 of time-based awards were granted to non-employee members of the Board which will vest in May 2024. A total of 872,660 of performance-based awards were granted, of which 436,330 of the awards vest based on a relative Total Shareholder Return ("TSR") calculation and 436,330 of the awards vest based on certain performance metrics of the Company. The non-TSR performance-based awards vest on March 5, 2026 based on the actual 2025 annual return on invested capital (ROIC). 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 $22.42. Similar TSR awards were granted during 2022 and 2021 with a grant date fair values of $34.41 and $29.07 which was calculated utilizing a Monte Carlo simulation. The following weighted-average assumptions were utilized to value the grants in 2023, 2022 and 2021: 2023 2022 2021 Dividend yield N/A 3.22 % 1.56 % Expected historical volatility 67.1 % 68.0 % 71.1 % Risk free interest rate 4.47 % 3.06 % 0.17 % Expected life (in years) 3 3 3 The following table presents a summary of activity for RSUs for 2023: Number of Shares Weighted Average Grant Date Fair Value Outstanding, January 1, 2023 3,790,404 $ 17.01 Granted 1,958,242 16.33 Vested (2,326,611) 11.72 Forfeited (103,691) 19.92 Outstanding, December 31, 2023 3,318,344 $ 20.22 Expected to vest, December 31, 2023 2,430,837 $ 19.36 The 2020 performance-based RSUs vested above target in 2023 and resulted in 122,834 additional RSU shares being granted and vested immediately. At December 31, 2023, there was $29 million of unrecognized compensation expense related to nonvested RSUs, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of 1.8 years. The weighted-average grant-date fair value of RSUs granted during 2023, 2022 and 2021 was $16.33 per unit, $19.47 per unit, and $20.91 per unit, respectively.

Retirement Benefits [Abstract]
Pension and Other Postretirement Healthcare Benefits	Pension and Other Postretirement Healthcare Benefits The following provides information regarding our U.S. and foreign plans: U.S. Plans Pension and Postretirement Healthcare Plans — Tronox has one main U.S. defined benefit plan: the U.S. Qualified Plan. The U.S. Qualified Plan is a funded noncontributory qualified benefit plan which is in accordance with the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Code. We made contributions into funds managed by a third party, and those funds are held exclusively for the benefit of the plan participants. Benefits under the U.S. Qualified Plan were generally calculated based on years of service and final average pay. The U.S. Qualified Plan was frozen and closed to new participants on June 1, 2009. In October 2022, the Company entered into an irrevocable arrangement with an insurance provider to settle certain lower dollar valued accounts within its frozen U.S Qualified Plan to reduce PBGC premiums. As a result of this arrangement, the Company recorded a non-cash pension settlement charge of approximately $20 million during the fourth quarter of 2022. We also maintain one postretirement healthcare plan - the U.S. retiree welfare plan. International Plans Pension Plans — Tronox has international defined benefit commitments primarily in the United Kingdom ("U.K. DB Scheme") and Saudi Arabia. The U.K. DB Scheme is a funded qualified defined benefit plan in the United Kingdom, which is frozen with no additional benefits accruing to the participants. Benefits under the U.K. DB Scheme are generally calculated based on years of credit service and final compensation when benefits ceased to accrue as defined under the plan provisions. We also maintain a Saudi Arabia Cristal End of Service Benefit plan which provides end of service benefits to qualifying participants. End of service benefits are based on years of service and the reasons for which a participant's services to the Company are terminated. Multiemployer Pension Plan - In prior periods, we maintained a defined benefit plan in the Netherlands (the “Netherlands Plan”) to provide defined pension benefits to qualifying employees of Tronox Pigments (Holland) B.V. and its related companies. During 2014, the Netherlands Plan was replaced with a multiemployer plan, the Netherlands Contribution Plan (the "CDC Plan") effective January 1, 2015. Under the CDC Plan, employees earn benefits based on their pensionable salaries each year determined using a career average benefit formula. The collective bargaining agreement between us and the participants require us to contribute 20.4% of the participants’ pensionable salaries into a pooled fund administered by the industry-wide PGB. The pensionable salary is the annual income of employees subject to a cap, which is adjusted each year to reflect the current requirements of the Netherlands’ Wages and Salaries Tax Act of 1964. Our obligation under this plan is limited to the fixed percentage contribution we make each year. The employees are entitled to any returns generated from the investment activities of the fund. The following table outlines the details of our participation in the CDC Plan for the year ended December 31, 2023. The CDC disclosures provided herein are based on the fund’s 2022 annual report, which is the most recently available public information. Based on the total plan assets and accumulated benefit obligation information in the plan’s annual report, the zone status was green as of December 31, 2022. A green zone status indicates that the plan was at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates whether a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. As of December 31, 2023, we are not aware of any financial improvement or rehabilitation plan being implemented or pending. The last column lists the expiration date of the collective-bargaining agreement to which the plan is subject. Pension Protection Act Zone Status Tronox Contributions Pension Fund EIN/Pension Plan Number 2023 2022 FIP/RP Pending/ Implemented 2023 2022 Surcharge Imposed Expiration date of Collective- Bargaining Agreement PGB NA N/A Green No $ 5 $ 5 No 12/31/2024 On the basis of the information available in the CDC Plan 2022 annual report, our contribution does not constitute more than 5 percent of the total contribution to the plan by all participants. During 2023, the fund did not impose any surcharge on us. Postretirement Healthcare Plans — We also maintain postretirement healthcare plans in South Africa (the "South African Plan") and Brazil (the "Brazil Medical Plan"). The South African Plan provides medical and dental benefits to certain South African employees, retired employees and their registered dependents. The South African Plan provides benefits as follows: (i) members employed before March 1, 1994 receive 100% post-retirement and death-in-service benefits; (ii) members employed on or after March 1, 1994 but before January 1, 2002 receive 2% per year of completed service subject to a maximum of 50% post-retirement and death-in-service benefits; and, (iii) members employed on or after January 1, 2002 receive no post-retirement and death-in-service benefits. The Brazil Medical Plan provides post-employment medical benefits to employees who contributed to the medical plan while employed. Retirees receiving a benefit under the plan are required to pay a contribution that varies based on the coverage level elected. Pension and Postretirement Benefit Costs / Obligations Benefit Obligations and Funded Status — The following provides a reconciliation of beginning and ending benefit obligations, beginning and ending plan assets, funded status, and balance sheet classification of our U.S. and international pension plans and other post-retirement benefit plans ("OPEB") as of and for the years ended December 31, 2023 and 2022.

(2) Since the benefits under the U.S Qualified Plan and the U.K. DB Scheme are frozen, the projected benefit obligation and accumulated benefit obligation are the same. Contributions At a minimum, Tronox contributes to its pension plans to comply with local regulatory requirements (e.g., ERISA in the United States). Discretionary contributions in excess of the local minimum requirements are made based on many factors, including long-term projections of the plans' funded status, the economic environment, potential risk of overfunding, pension insurance costs and alternative uses of the cash. Changes to these factors can impact the timing of discretionary contributions from year to year. Pension contributions for its US and international plans were approximately $6 million in 2023 and are currently expected to be approximately $8 million in 2024. The following table provides information for pension plans where the accumulated benefit obligation exceeds the fair value of the plan assets: Pensions 2023 US International Projected benefit obligation (PBO) $ 198 $ 63 Accumulated benefit obligation (ABO) $ 198 $ 42 Fair value of plan assets $ 175 $ — Expected Benefit Payments — The following table shows the expected cash benefit payments for the next five years and in the aggregate for the years 2029 through 2033: 2024 2025 2026 2027 2028 2029-2032 Pensions - US $ 19 $ 19 $ 19 $ 18 $ 17 $ 76 Pensions - International $ 13 $ 9 $ 10 $ 10 $ 11 $ 51 Other Post Retirement Benefit Plans - US $ — $ — $ — $ — $ — $ 1 Other Post Retirement Benefit Plans - International $ — $ 1 $ 1 $ 1 $ 1 $ 10 Retirement and Postretirement Healthcare Expense — The table below presents the components of net periodic cost associated with the U.S. and foreign plans recognized in the Consolidated Statements of Operations for 2023, 2022, and 2021: Pensions Other Postretirement Benefit Plans Year Ended December 31, Year Ended December 31, 2023 2022 2021 2023 2022 2021 Net periodic cost: Service cost $ 3 $ 5 $ 4 $ 1 $ — $ 1 Interest cost (1) 18 14 14 2 2 2 Expected return on plan assets (1) (20) (24) (26) — — — Net amortization of actuarial loss (1) — 4 5 — — 1 Settlement losses (gains) (1) — 20 — — — — Curtailment (gains) (1) — — — — — — Total net periodic cost $ 1 $ 19 $ (3) $ 3 $ 2 $ 4 ________________ (1) Recorded in Other income (expense), net in the Consolidated Statements of Operations.

Expected Return on Plan Assets — In forming the assumption of the U.S. and international long-term rate of return on plan assets, we considered the expected earnings on funds already invested, earnings on contributions expected to be received in the current year, and earnings on reinvested returns. The long-term rate of return estimation methodology for the Company's pension plans is based on a capital asset pricing model using historical data and a forecasted earnings model. An expected return on plan assets analysis is performed which incorporates the current portfolio allocation, historical asset-class returns, and an assessment of expected future performance using asset-class risk factors. Discount Rate — The 2023 and 2022 rates were selected based on the results of a cash flow matching analysis, which projected the expected cash flows of the plans using a yield curves model developed from a universe of Aa-graded U.S. currency corporate bonds (obtained from Bloomberg) with BVAL scores of 6 or greater. Plan Assets — The investments of the U.S. and International pension plans are managed to meet the future expected benefit liabilities of the plan over the long term by investing in diversified portfolios consistent with prudent diversification and historical and expected capital market returns . Tronox's U.S. and international pension plans’ weighted-average asset allocations at December 31, 2023 and 2022, and the target asset allocation ranges, by major asset category, are as follows: December 31, 2023 2022 US International US International Actual Target Actual Target Actual Target Actual Target Equity securities 49 % 50 % — % — % 49 % 46 % — % — % Debt securities 47 47 38 38 46 46 37 37 Real estate 1 1 — — 1 — — — Other 3 2 62 62 4 8 63 63 Total 100 % 100 % 100 % 100 % 100 % 100 % 100 % 100 % The fair values of pension investments as of December 31, 2023 are summarized below: Fair Value Measurement at December 31, 2023 Using: Quoted Prices Significant Other Significant Total Asset category: Equities securities: Global equity securities $ 48 (1) $ — $ — $ 48 Global commingled equity funds 38 (2) — — 38 Debt securities: US government bonds 48 (3) — — 48 Foreign government bonds 22 (3) — — 22 US corporate bonds — 34 (4) — 34 Foreign corporate bonds — 21 (4) — 21 Real Estate: Property/ real estate fund — 1 (5) — 1 Other: Insurance contracts — — 63 (7) 63 Cash & cash equivalents 10 (6) — — 10 Total at fair value $ 166 $ 56 $ 63 $ 285 ________________ (1) For global equity securities, this category is comprised of shares of common stock in both U.S. and international companies from a diverse set of industries and size.

Under the SIP, our regular full-time and part-time employees contribute a portion of their earnings, and we match these contributions up to a predefined threshold. Our matching contribution is 100% of the first 6% of employee contributions. Effective January 1, 2013, we established a profit sharing contribution at 6% of employees’ pay (“discretionary contribution”). A discretionary contribution of 6% was made for 2023, 2022 and 2021. Our matching contribution to the SIP vests immediately; however, our discretionary contribution is subject to vesting conditions that must be satisfied over a three-year vesting period. Contributions under the SIP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expenses associated with our matching contribution to the SIP was $4 million, $5 million and $5 million during 2023, 2022 and 2021, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. Compensation expense associated with our discretionary contribution was $5 million in 2023, $5 million in 2022 and $5 million in 2021, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. U.S. Benefit Restoration Plan In 2006, we established the U.S. Benefit Restoration Plan (the “BRP”), a nonqualified defined contribution plan, for employees whose eligible compensation is expected to exceed the IRS compensation limits for qualified plans. Under the BRP, participants can contribute up to 20% of their annual compensation and incentive. Our matching contribution under the BRP is the same as the SIP. Our matching contribution under this plan vests immediately to plan participants. Contributions under the BRP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expense associated with our matching contribution to the BRP was $1 million, $1 million and $1 million during 2023, 2022 and 2021, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. South Africa Defined Contribution Plans Tronox Mineral Sands Proprietary Limited, a wholly owned subsidiary of the Company, participates in several defined contribution plans which are registered in the Republic of South Africa and are governed by the South African Pension Funds Act of 1956. These plans provide retirement and other benefits to all permanent employees, and where applicable, retired employees and their dependents. The Company contributes a range of 10% to 15% (depending on the plan) of the employees' predefined pre-tax pensionable earnings. Compensation expense associated with these plans was $8 million, $7 million, and $5 million during 2023, 2022 and 2021, respectively, which was included in both "Costs of goods sold" and "Selling, general and administrative expenses" in the Consolidated Statements of Operations.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Tasnee / Cristal At December 31, 2023 Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a subsidiary of Tasnee, continues to own 37,580,000 shares of Tronox, or a 24% ownership interest. 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 AMIC Debt would remain outstanding debt of the SPV upon exercise of the Option. 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 we lent AMIC $125 million for capital expenditures and operational expenses intended to facilitate the start-up of the Slagger (the “Tronox Loans”). 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 (i) our forgiveness of the Tronox Loans principal and accrued interest thereon, and (ii) the SPV's assumption of $36 million of indebtedness plus accrued interest thereon lent by AMIC to the SPV. Under the First Amendment, the SPV would not assume any of the AMIC Debt. On May 10, 2023, AMIC and Tronox further amended the Option Agreement (the “Second Amendment”). In the Second Amendment the parties acknowledged that the Option expired on May 10, 2023 without being exercised but agreed to continue negotiating until September 30, 2023 (the "Renegotiation Period") as to whether, and under what circumstances, Tronox may acquire the Slagger. Subsequent to September 30, 2023, the parties continued to negotiate as to whether, and under what circumstances, Tronox may acquire the Slagger and on February 21, 2024 they again amended the Option Agreement (the “Third Amendment”), which extended the Renegotiation Period until the earlier of the repayment of the Tronox Loans or December 31, 2024, subject to certain early termination rights. The Third Amendment also provided that from the date the parties entered into the Second Amendment and through December 31, 2023, all chloride slag produced by the Slagger was to be delivered to Tronox as repayment in-kind of the Tronox Loans at a price based on a widely published index for feedstock less a nominal discount (the “Slag Price”). T hereafter and until the end of the Renegotiation Period, 65% of all chloride slag produced by the Slagger will be delivered to Tronox as repayment in-kind of the Tronox Loans based on the Slag Price and Tronox will purchase via cash settlements the remaining 35% at the Slag Price. Full repayment of the Tronox Loans is required by January 2025 in either cash or in-kind through chloride slag deliveries. During July 2023, we also entered into an agreement with AMIC to act as their sales agent with regard to sales of slag fines to customers outside of the Kingdom of Saudi Arabia for an agreed upon commission fee to be paid.

Through September 30, 2023 we provided technical advice and project management services, however AMIC and its consultants were still responsible for engineering and construction of the Slagger. As compensation for these services, Tronox received certain fees, including a management fee. In the Consolidated Statement of Operations and shown in the table below, the management fees per the Original Technical Services Agreement were recorded within "Other income, net" and other technical support fees, including fees per the Restated Technical Services Agreement, are recorded within "Selling, general and administrative" costs. From and after October 1, 2023, we no longer receive a management fee and the scope of services we provide is more limited, for which we receive cost reimbursement plus a nominal margin.

Consideration for the acquisition was the assumption by Tronox of a $36 million note payable to Cristal (the "MGT Loan"). 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 TiCl4, which we supply by pipeline, for the production of titanium sponge, a precursor material used in the production of titanium metal. On December 17, 2020 we completed the MGT transaction. Repayment of the $36 million note payable is based on a fixed U.S. dollar per metric ton quantity of MGT delivered by us to ATTM over time and therefore the ultimate maturity date is variable in nature. If ATTM fails to purchase MGT from us under certain contractually agreed upon conditions, then at our election we may terminate the MGT supply agreement with ATTM and will no longer owe any amount under the loan agreement with Cristal. We currently estimate the ultimate maturity to be between approximately four December 31, 2023 2022 Note payable, due within 1 year 7 7 Note payable, due longer than 1 year from now 18 23 Total outstanding note payable 25 30 Amounts regarding interest expense and loan repayments for the MGT loan, which are recorded on the Consolidated Statement of Operations within “Interest expense” and “Net sales,” respectively, are shown below: December 31, 2023 2022 2021 Interest expense 2 1 1 Loan Repayment via MGT delivered to ATTM 6 3 4 As a result of these transactions we have entered into related to the MGT assets, Tronox purchases chlorine gas from ATTM for use in the production of MGT and such transactions are reflected as follows: December 31, 2023 2022 2021 Purchases of chlorine gas 5 4 8 These purchases are subsequently recorded within “Cost of goods sold” on the Consolidated Statement of Operations.

Segment Reporting [Abstract]
Segment Information	Segment Information We operate our business under one operating segment, Tronox , which is also our reportable segment. The Company's chief operating decision maker, who are its Co-CEOs, reviews financial information presented at the consolidated level for purposes of allocating resources and evaluating financial performance. Since we operate our business under one segment, there is no difference between our consolidated results and segment results. We disaggregate revenue from contracts with customers by product type and geographic area as well as sales based on country of production. 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. During 2023, 2022 and 2021 our ten largest third-party customers represented 39%, 30%, and 28%, respectively, of our consolidated net sales. During 2023, 2022, and 2021, no single customer accounted for 10 % of our consolidated net sales. Net sales to external customers based on country of production, were as follows: Year Ended December 31, 2023 2022 2021 U.S. operations $ 686 $ 733 $ 716 International operations: United Kingdom 267 331 396 Australia 659 822 873 South Africa 398 484 441 Saudi Arabia 318 419 420 Other - international 522 665 726 Total net sales $ 2,850 $ 3,454 $ 3,572 See Note 3 for further information on revenues. There is no difference between the total consolidated assets and our segment assets. Property, plant and equipment, net, mineral leaseholds, net, and lease right of use assets, net by geographic region, were as follows: December 31, 2023 2022 U.S. operations $ 299 $ 308 International operations: United Kingdom 103 93 Saudi Arabia 222 226 South Africa 701 705 Australia 1,048 1,093 Other - international 248 242 Total $ 2,621 $ 2,667

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation We are considered a domestic company in the United Kingdom and, as such, are required to comply with filing requirements in the United Kingdom. Additionally, we are not considered a “foreign private issuer” in the U.S.; therefore, we are required to comply with the reporting and other requirements imposed by the U.S. securities law on U.S. domestic issuers, which, among other things, requires reporting under accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements included in this Form 10-K are prepared in conformity with U.S. GAAP. Our consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period.
Use of Estimates	Use of Estimates 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.
Foreign Currency	Foreign Currency The U.S. dollar is our reporting currency for our consolidated financial statements in U.S. GAAP. We determine the functional currency of each subsidiary based on a number of factors, including the predominant currency for revenues, expenditures and borrowings. Adjustments from the remeasurement of non-functional currency monetary assets and liabilities are recorded in “Other income (expense), net” in the Consolidated Statements of Operations. When a subsidiary’s functional currency is not the U.S. dollar, translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are recorded in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. Translation adjustments on intercompany foreign currency receivables and payables that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments.
Revenue Recognition	Revenue Recognition 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. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as “Net sales” in the Consolidated Statements of Operations. Accruals are made for sales returns, rebates and other allowances, which are recorded in “Net sales” in the Consolidated Statements of Operations and are based on our historical experience and current business conditions. Additionally, we have elected the practical expedient to exclude sales taxes and similar taxes that we collect from customers on behalf of government authorities from the revenue transaction price. See Note 3.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes costs for purchasing, receiving, manufacturing, and distributing products, including raw materials, energy, labor, depreciation, depletion, shipping and handling, freight, warehousing, and other production costs.
Research and Development	Research and Development Research and development costs, included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations comprised of salaries, building costs, utilities, administrative expenses, third party research, and allocations of corporate costs, were $12 million, $12 million, and $13 million during 2023, 2022, and 2021, respectively, and were expensed as incurred.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative expenses include costs related to marketing, research and development, agent commissions, and legal and administrative functions such as corporate management, human resources, information technology, investor relations, accounting, treasury, and tax compliance.
Income Taxes	Income Taxes We use the asset and liability method of accounting for income taxes. The estimation of the amounts of income taxes involves the interpretation of complex tax laws and regulations and how foreign taxes affect domestic taxes, as well as the analysis of the realizability of deferred tax assets, tax audit findings, and uncertain tax positions. Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided against a deferred tax asset when it is more likely than not that all or some portion of the deferred tax asset will not be realized. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes in our estimates in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income (loss), as appropriate. All available positive and negative evidence is weighed to determine whether a valuation allowance should be recorded. The amount of income taxes we pay is subject to ongoing audits by federal, state, and foreign tax authorities, which may result in proposed assessments. Our estimate of the potential outcome for any uncertain tax issue is highly judgmental. We assess our income tax positions, and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, we record the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties are accrued as part of tax expense, where applicable. If we do not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. See Note 5.
Fair Value Measurement	Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities; • Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and, • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities See Note 15.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all investments with original maturities of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are generally highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk.
Accounts Receivable, net of allowance for credit losses	Accounts Receivable, net of allowance for credit losses We perform credit evaluations of our customers, and take actions deemed appropriate to mitigate credit risk. Only in certain specific occasions do we require collateral in the form of bank or parent company guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions.
Inventories, net	Inventories, net Pigment inventories are stated at the lower of actual cost and net realizable value, net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method. Carrying values include material costs, labor, and associated indirect manufacturing expenses. Costs for materials and supplies, excluding titanium ore, are determined by average cost to acquire. Feedstock and co-products inventories including titanium ore are stated at the lower of the weighted-average cost of production or market. Inventory costs include those costs directly attributable to products, including all manufacturing overhead but excluding distribution costs. Raw materials are carried at actual cost. We review the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence. In either case, we record any write-down equal to the difference between the cost of inventory and its estimated net realizable value based on assumptions about alternative uses, market conditions and other factors. Inventories expected to be sold or consumed within twelve months after the balance sheet date are classified as current assets and all other inventories are classified as non-current assets. See Note 8.
Long Lived Assets	Long Lived Assets Property, plant and equipment, net is stated at cost less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Land improvements 10 — 20 years Buildings 10 — 40 years Machinery and equipment 3 — 25 years Furniture and fixtures 10 years Maintenance and repairs are expensed as incurred, except for costs of replacements or renewals that improve or extend the lives of existing properties, which are capitalized. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is included in “Cost of goods sold” or “Selling, general, and administrative expenses” in the Consolidated Statements of Operations. See Note 9. We capitalize costs associated with our asset retirement obligations which are generally included in machinery and equipment. See Note 17. We capitalize interest costs on major projects that require an extended period of time to complete. See Note 13. Mineral property acquisition costs are capitalized as tangible assets when management determines that probable future benefits consisting of a contribution to future cash inflows have been identified and adequate financial resources are available or are expected to be available as required to meet the terms of property acquisition and anticipated exploration and development expenditures. Mineral leaseholds are depleted over their useful lives as determined under the units of production method. Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves, the costs incurred to develop such property through the commencement of production are capitalized. See Note 10. Intangible assets are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated useful lives, which generally range from 3 to 20 years. See Note 11. We evaluate the recoverability of the carrying value of long-lived assets that are held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Under such circumstances, we assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are not sufficient, we calculate the impairment amount by discounting the projected cash flows using our weighted-average cost of capital. For assets that satisfy the criteria to be classified as held for sale, an impairment loss, if any, is recognized to the extent the carrying amount exceeds fair value, less cost to sell. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined.
Leases	Leases We determine if a contract is or contains a lease at inception of the contract. Our leases are primarily operating leases. Leased assets primarily include office buildings, rail cars and motor vehicles, forklifts, and other machinery and equipment. Our leases primarily have fixed lease payments, with real estate leases typically requiring additional payments for real estate taxes and occupancy-related costs. Certain of our leases also have variable lease payments. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index) are included in our initial measurement of the lease right of use assets and lease liabilities. Variable lease payments that are not index or rate based (such as variable payments based on our performance or use of the leased assets) are recorded as expenses when incurred and excluded from the measurement of right of use assets and lease liabilities. Our leases typically have initial lease terms ranging from 1 to 25 years. Some of our lease agreements include options to renew, extend or early terminate the leases. Lease term is the non-cancellable period of a lease, adjusted by the period covered by an option to extend or terminate the lease if we are reasonably certain to exercise (or not exercise) that option. Our operating leases typically do not contain purchase options we expect to exercise, residual value guarantees or other material covenants. Operating leases are recorded under “Lease right of use assets”, “Short-term lease liabilities”, and “Long-term lease liabilities” on the Consolidated Balance Sheets. Finance leases are recorded under “Property, plant and equipment net”, “Long-term debt due within one year”, and “ Long-term debt
Long-term Debt	Long-term Debt Long-term debt is stated net of unamortized original issue premium or discount. Premiums or discounts are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. Deferred debt issuance costs related to a recognized debt liability are presented in the Consolidated Balance Sheets as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts and are amortized using the effective interest method with amortization expense recorded in “Interest and debt expense, net” in the Consolidated Statements of Operations. See Note 13.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations are recorded at their estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Fair value is measured using expected future cash outflows discounted at our credit-adjusted risk-free interest rate, which are considered Level 3 inputs. We classify accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” in the Consolidated Statements of Operations. See Note 17.
Environmental Remediation and Other Contingencies	Environmental Remediation and Other Contingencies We record an undiscounted liability when any of the following occur: 1) a claim or assessment has been asserted, 2) a litigation has commenced, or 3) based on available information, it is probable that a claim or an assessment will be asserted or a litigation will commence; and in addition, the outcome is expected to be unfavorable to us and the associated costs can be reasonably estimated. See Note 18.
Self-Insurance	Self-Insurance We are self-insured for certain levels of general and vehicle liability, property, workers’ compensation and health care coverage. The cost of these self-insurance programs is accrued based upon estimated fully developed settlements for known and anticipated claims. Any resulting adjustments to previously recorded reserves are reflected in current operating results. We do not accrue for general or unspecific business risks.
Share-based Compensation	Share-based Compensation Equity Restricted Share and Restricted Share Unit Awards — The fair value of equity instruments is measured based on the share price on the grant date and is recognized over the vesting period. These awards contain service, market, and/or performance conditions. For awards containing only a service or a market condition, we have elected to recognize compensation costs using the straight-line method over the requisite service period for the entire award. For awards containing a market condition, the fair value of the award is measured using the Monte Carlo simulation under a lattice model approach. For awards containing a performance condition, the fair value is the grant date close price and compensation expense is not recognized until we conclude that it is probable that the performance condition will be met. We reassess the probability at least quarterly. See Note 20.
Defined Benefit Pension and Postretirement Benefit Plans	Defined Benefit Pension and Postretirement Benefit Plans We recognize the funded status of our defined benefit pension plans and postretirement benefit plans in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. The benefit obligation for the defined benefit plans is the projected benefit obligation (PBO), which represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The benefit obligation for our postretirement benefit plans is the accumulated postretirement benefit obligation (APBO), which represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets related to our defined benefit plan represents the current market value of assets held in a trust fund, which is established for the sole benefit of plan participants. If the fair value of plan assets exceeds the benefit obligation, the plan is overfunded, and the excess is recorded as a prepaid pension asset. On the other hand, if the benefit obligation exceeds the fair value of plan assets, the plan is underfunded, and the deficit is recorded as pension and postretirement healthcare benefits obligation in the Consolidated Balance Sheet. The portion of the pension and postretirement healthcare obligations payable within the next 12 months is recorded in accrued liabilities in the Consolidated Balance Sheet. Net periodic pension and postretirement benefit cost represents the aggregation of service cost, interest cost, expected return on plan assets, amortization of prior service costs or credits and actuarial gains or losses previously recognized as a component of OCI and it is recorded in the Consolidated Statements of Operations. Net periodic cost is recorded in cost of goods sold and selling, general and administrative expenses in the Consolidated Statements of Operations based on the employees’ respective functions. Actuarial gains or losses represents the effect of remeasurement on the benefit obligation principally driven by changes in the plan actuarial assumptions. Prior service costs or credits arise from plan amendments. The actuarial gains or losses and prior service costs or credits are initially recognized as a component of Other comprehensive income (loss) in the Consolidated Statement of Comprehensive Income. Those gains or losses and prior service costs or credits are subsequently recognized as a component of net periodic cost. The measurement of benefit obligations and net periodic cost is based on estimates and assumptions approved by management. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain assumptions, including estimates of discount rates, expected return on plan assets, rate of compensation increases and mortality rates. Defined Contribution Plans — We recognize our contribution as expense when they are due. The expense is recorded in cost of goods sold or selling, general and administrative expenses the Consolidated Statements of Operations based on the employees’ respective functions. Multiemployer Plan — We treat our multiemployer plan like a defined contribution plan. A pension plan to which two or more unrelated employers contribute is generally considered to be a multiemployer plan. As a defined contribution plan, we recognize the contribution for the period as a net benefit cost and any contributions due and unpaid as a liability.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, "Improvements to Reportable Segment Disclosures". The amendment requires additional disclosures by public entities, including those with a single reportable segment, to disclose significant segment expenses and other segment items for each reportable segment. The guidance applies to fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating any incremental disclosures required as a result of this standard. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amendments in this update apply to all entities that are subject to Topic 740, Income Taxes. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The amendments in this update are effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. We are currently evaluating any incremental disclosures required as a result of this standard. Recently Adopted 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.
