The Company

The Company	12 Months Ended
	Dec. 31, 2015
The Company [Abstract]
The Company	1. The Company Tronox Limited and its subsidiaries (collectively referred to as “Tronox,” “we,” “us,” or “our”) is a public limited company registered under the laws of the State of Western Australia. We are a global leader in the production and marketing of titanium bearing mineral sands and titanium dioxide (“TiO 2 2 2 We have global operations in North America, Europe, South Africa, and the Asia-Pacific region. Within our TiO 2 On April 1, 2015 (the “Alkali Transaction Date”), we completed the acquisition of 100% of the Alkali Chemicals business (“Alkali”) from FMC Corporation (“FMC”) for an aggregate purchase price of $1.65 billion in cash (the “Alkali Transaction”). See Note 4 for additional information regarding the Alkali Transaction. As a result of the Alkali Transaction, we produce natural soda ash from a mineral called trona, which we mine at two facilities we own near Green River, Wyoming. Our Wyoming facilities process the trona ore into chemically pure soda ash and specialty sodium products such as sodium bicarbonate (baking soda). We sell soda ash directly to customers in the United States, Canada and Europe and to the American Natural Soda Ash Corporation (“ANSAC”), a non-profit foreign sales association in which we and two other U.S. soda ash producers are members, for resale to customers elsewhere around the world. We use a portion of our soda ash at Green River to produce specialty sodium products such as sodium bicarbonate and sodium sesquicarbonate that have uses in food, animal feed, pharmaceutical, and medical applications. In June 2012, Tronox Limited issued Class B ordinary shares (“Class B Shares”) to Exxaro Resources Limited (“Exxaro”) and one of its subsidiaries in consideration for 74% of Exxaro’s South African mineral sands business, and the existing business of Tronox Incorporated was combined with the mineral sands business in an integrated series of transactions whereby Tronox Limited became the parent company (the “Exxaro Transaction”). Exxaro has agreed not to acquire any voting shares of Tronox Limited if, following such acquisition, Exxaro will have a voting interest in Tronox Limited of 50% or more unless Exxaro brings any proposal to make such an acquisition to the Board of Directors of Tronox Limited on a confidential basis. In the event an agreement regarding the proposal is not reached, Exxaro is permitted to make a takeover offer for all the shares of Tronox Limited not held by affiliates of Exxaro, subject to certain non-waivable conditions. At December 31, 2015, Exxaro held approximately 44% of the voting securities of Tronox Limited. See Note 24 for additional information regarding Exxaro transactions. Basis of Presentation We are considered a domestic company in Australia and, as such, are required to report in Australia under International Financial Reporting Standards (“IFRS”). Additionally, as we are not considered a “foreign private issuer” in the United States (“U.S.”), 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. We publish our consolidated financial statements, in both U.S. GAAP and IFRS, in U.S. dollars. Exxaro has a 26% ownership interest in each of our Tronox KZN Sands (Pty) Ltd. and Tronox Mineral Sands (Pty) Ltd. subsidiaries in order to comply with the ownership requirements of the Black Economic Empowerment (“BEE”) legislation in South Africa. We account for such ownership interest as “Noncontrolling interest” in our consolidated financial statements. See Note 21. 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. For the year ended December 31, 2013, we decreased cash flows from investing activities by $7 million with a corresponding decrease in cash flows from operating activities to adjust for accrued capital expenditures. During the year ended December 31, 2014, we recorded out-of-period adjustments that should have been recorded during 2012 that decreased cost of goods sold by $6 million, decreased loss before income taxes by $6 million, decreased net loss by $5 million and decreased loss per share by $0.03. Also during the year ended December 31, 2014, we recorded out-of-period adjustments that should have been recorded during 2013 that increased cost of goods sold by $6 million, increased selling, general and administrative expenses by $1 million, increased loss before income taxes by $7 million, increased net loss by $5 million and increased loss per share by $0.04. After evaluating the quantitative and qualitative aspects of the adjustments, we concluded the effect of these adjustments, individually and in the aggregate, was not material to our previously issued consolidated financial statements or to our 2014 consolidated financial statements. During the year ended December 31, 2015, we recorded out-of-period adjustments that should have been recorded in 2012 through 2014 that decreased cost of goods sold by $5 million, decreased loss before income taxes by $5 million, decreased net loss by $3 million, and decreased loss per share by $0.02. After evaluating the quantitative and qualitative aspects of the adjustments, we concluded the effect of these adjustments, individually and in the aggregate, was not material to our previously issued consolidated financial statements and is not material to our 2015 consolidated financial statements. 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.

Significant Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Foreign Currency The U.S. dollar is the functional currency for our operations, except for our South African operations, whose functional currency is the Rand, and our European operations, whose functional currency is the Euro. 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 the 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. Gains and losses on intercompany foreign currency transactions that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments. Revenue Recognition Revenue is recognized when risk of loss and title to the product is transferred to the customer, pricing is fixed or determinable, and collection is reasonably assured. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as net sales. 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. 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 Operation comprising of salaries, building costs, utilities, administrative expenses, and allocations of corporate costs, were $13 million, $11 million, and $10 million during 2015, 2014, and 2013, respectively, and were expensed as incurred. Selling, General and Administrative Expenses Selling, general and administrative expenses include costs related to marketing, 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 weighted 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 for 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 7. Earnings per Share Basic and diluted earnings per share are calculated using the two-class method. Under the two-class method, earnings used to determine basic earnings per share are reduced by an amount allocated to participating securities. Participating securities include restricted shares issued under the Tronox Management Equity Incentive Plan (see Note 22) and the T-Bucks Employee Participation Plan (see Note 22), both of which contain non-forfeitable dividend rights. Our unexercised options, unexercised Series A and Series B Warrants (see Note 20), and unvested restricted share units do not contain non-forfeitable rights to dividends and, as such, are not considered in the calculation of basic earnings per share. Our unvested restricted shares do not have a contractual obligation to share in losses; therefore, when we record a net loss, none of the loss is allocated to participating securities. Consequently, in periods of net loss, the two class method does not have an effect on basic loss per share. Diluted earnings per share is calculated by dividing net earnings allocable to ordinary shares by the weighted-average number of ordinary shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating restricted share units, options, and Series A and Series B Warrants. The options and Series A and Series B Warrants are included in the calculation of diluted earnings per ordinary share utilizing the treasury stock method. See Note 8. 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 9. 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 December 31, 2015 and 2014, we had restricted cash in Australia related to outstanding performance bonds of $5 million and $3 million, respectively. Accounts Receivable, net of allowance for doubtful accounts 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 parental guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions. See Note 10. Inventories, net Pigment and Alkali inventories are stated at the lower of actual cost or market (“LOCM”), net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method (“FIFO”). 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. Mineral Sands 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, annually and at the end of each quarter, the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence (inventory that is no longer marketable for its intended use). 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 11. 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 12. We capitalize interest costs on major projects that require an extended period of time to complete. See Note16. 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 13. Intangible assets are stated at cost less accumulated amortization, and are amortized on a straight-line basis over their estimated useful lives, which range from 3 to 20 years. See Note 14. We evaluate the recoverability of the carrying value of long-lived assets 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. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined. Business Acquisitions Business acquisitions are accounted for using the acquisition method under Accounting Standards Codification (“ASC”) 805, Business Combinations 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 are recorded in “Other long-term assets” in the Consolidated Balance Sheets, 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 16. 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 Note17. Derivative Instruments Derivative instruments are recorded in the Consolidated Balance Sheets at their fair values. Changes in the fair value of derivative instruments not designated for hedge accounting treatment are recorded in “Other income (expense), net” in the Consolidated Statements of Operations. See Note 18. Environmental Remediation and Other Contingencies We recognize a loss and record an undiscounted liability when litigation has commenced or a claim or assessment has been asserted, or, based on available information, commencement of litigation or assertion of a claim or assessment is probable, and the associated costs can be reasonably estimated. See Note 19. 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.

Restructuring Expense [Abstract]
Restructuring Expense	3. Restructuring Expense During 2014, we initiated a cost improvement initiative. The initiative resulted in a reduction in our workforce by approximately 135 employees and outside contractor positions. At December 31, 2014, the remaining liability was $4 million. During 2015, we paid $4 million of cash related to such restructuring. In November 2015 we ceased production at our sodium chlorate plant in Hamilton, Mississippi resulting in a reduction in our workforce of approximately 50 employees. This action resulted in a charge, consisting primarily of employee severance costs, of $4 million, which was recorded in “Restructuring expense” in the Consolidated Statements of Operations of which $1 million was paid during 2015. We expect to pay the remaining $3 million liability in 2016. In line with our goal of aligning production output to market requirements, during the third quarter of 2015, we decided that the operation of our Cooljarloo North Mine in Western Australia would be suspended on December 31, 2015, resulting in a reduction in our workforce of approximately 30 employees. This action resulted in a charge, consisting primarily of employee severance costs, of $3 million, which was recorded in “Restructuring expense” in the Consolidated Statements of Operations and paid during 2015. In 2015, as part of our commitment to reduce operating costs and working capital, we have commenced a global restructuring of our TiO 2 2 2 A summary in the changes in the liability established for restructuring, which is included in “Accrued liabilities” in the Consolidated Balance Sheet, is as follows: Restructuring Liability Balance, January 1, 2014 $ — Severance and other related costs 15 Cash payments (10 ) Noncash expense (1 ) Balance, December 31, 2014 $ 4 Severance and other related costs 21 Cash payments (10 ) Balance, December 31, 2015 $ 15 Restructuring expense by segment during 2015 and 2014 was as follows: Year Ended December 31 2015 2014 TiO 2 $ 20 $ 12 Corporate 1 3 Total $ 21 $ 15

Acquisition of Alkali Chemicals Group [Abstract]
Acquisition of Alkali Chemicals Group	4. Acquisition of Alkali Chemicals Group On April 1, 2015, we acquired Alkali because it diversifies our end markets and revenue base, and increases our participation in faster growing emerging market economies. We believe it also provides us greater opportunity to utilize a portion of our U.S. tax attributes in future periods. See Note 7 for a discussion of the tax impact of the Alkali Transaction. We accounted for the Alkali Transaction using the acquisition method under ASC 805 which requires recording assets acquired and liabilities assumed at fair value. Under the acquisition method of accounting, the assets acquired and liabilities assumed were recorded based on their preliminary estimated fair values on the Alkali Transaction Date. The results of the Alkali chemical business are included in the Alkali segment. The initial valuations were derived from estimated fair value assessments and assumptions used by management, and are preliminary. Further adjustments may result before the end of the measurement period, which ends no later than March 31, 2016. We funded the Alkali Transaction through existing cash and new debt. See Note 16 for further details of the Alkali Transaction financing. Purchase Price Allocation Valuation Consideration: Purchase price $ 1,650 Fair Value of Assets Acquired and Liabilities Assumed: Current Assets: Accounts receivable $ 147 Inventories 48 Prepaid and other assets 32 Total Current Assets 227 Property, plant and equipment (1) 767 Mineral leaseholds (2) 739 Other long-term assets 3 Total Assets $ 1,736 Current Liabilities: Accounts payable 46 Accrued liabilities 28 Total Current Liabilities 74 Noncurrent Liabilities: Other 12 Total Liabilities 86 Net Assets $ 1,650 (1) The fair value of property, plant and equipment was determined using the cost approach, which estimates the replacement cost of each asset using current prices and labor costs, less estimates for physical, functional and technological obsolescence, based on the estimated useful life ranging from 5 to 38 years. (2) The fair value of mineral rights was determined using the Discounted Cash Flow (“DCF” ) method, which was based upon the present value of the estimated future cash flows for the expected life of the asset taking into account the relative risk of achieving those cash flows and the time value of money. A discount rate of 10.4% was used taking into account the risks associated with such assets. There are no contingent liabilities currently recorded in the fair value of net assets acquired as of the Alkali Transaction Date, and the fair value of net assets acquired includes accounts receivables with book value that approximates fair value. Condensed Combined Financial Information The following condensed financial information presents the resulting operations of Alkali from the Alkali Transaction Date to December 31, 2015: For the period April 1, 2015 through December 31, 2015 Net sales $ 602 Income from operations $ 69 Net income $ 52 Supplemental Pro forma financial information The following unaudited pro forma information gives effect to the Alkali Transaction as if it had occurred on January 1, 2014. The unaudited pro forma financial information reflects certain adjustments related to the acquisition, such as (1) conforming the accounting policies of Alkali to those applied by Tronox, (2) recording certain incremental expenses resulting from purchase accounting adjustments, such as incremental depreciation expense in connection with fair value adjustments to property, plant and equipment, and depletion expense in connection with fair value adjustments to mineral leaseholds, (3) to record the effect on interest expense related to borrowings in connection with the Alkali Transaction and (4) to record the related tax effects. The unaudited pro forma financial information was adjusted to include the effect of certain non-recurring items as of January 1, 2014 such as the impact of transaction costs related to the Alkali Transaction of approximately $29 million, inventory step-up amortization of $9 million and $8 million of interest expense incurred on the Bridge Facility (see Note 16). All of these non-recurring costs were excluded from the 2015 supplemental pro forma information. The unaudited pro forma financial information is for illustrative purposes only and should not be relied upon as being indicative of the historical results that would have been obtained if the Alkali Transaction had actually occurred on that date, nor the results of operations in the future. In accordance with ASC 805, the supplemental pro forma results of operations for 2015 and 2014, as if the Alkali Transaction had occurred on January 1, 2014, are as follows: Year Ended December 31, 2015 2014 Net sales $ 2,307 $ 2,520 Income (loss) from operations $ (67 ) $ 67 Net loss $ (260 ) $ (405 ) Loss per share, basic and diluted $ (2.25 ) $ (3.54 )

Liquidation of Non-Operating Subsidiaries	5. Liquidation of Non-Operating Subsidiaries During 2014, we completed the liquidation of a non-operating subsidiary, Tronox Pigments International GmbH, for which we recognized a noncash loss from the realization of cumulative translation adjustments of $35 million, which was recorded in “Net gain (loss) on liquidation of non-operating subsidiaries” in the Consolidated Statements of Operations. During 2013, we completed the liquidation of two non-operating subsidiaries, Tronox (Luxembourg) Holdings S.a.r.l. and Tronox Luxembourg S.a.r.l., for which we recognized a net noncash gain from the realization of cumulative translation adjustments of $24 million, which was recorded in “Net gain (loss) on liquidation of non-operating subsidiaries” in the Consolidated Statements of Operations.

Income Taxes [Abstract]
Income Taxes	7. 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, 2015 2014 2013 Australia $ (353 ) $ (242 ) $ (185 ) International 87 93 124 Loss before income taxes $ (266 ) $ (149 ) $ (61 ) The income tax benefit (provision) is summarized below: Year Ended December 31, 2015 2014 2013 Australian: Current $ (17 ) $ (15 ) $ (11 ) Deferred — (183 ) 35 International: Current (24 ) (15 ) (23 ) Deferred (55 ) (30 ) Income tax benefit (provision) $ (41 ) $ (268 ) $ (29 ) The following table reconciles the applicable statutory income tax rates to our effective income tax rates for “Income tax benefit (provision)” as reflected in the Consolidated Statements of Operations. Year Ended December 31, 2015 2014 2013 Statutory tax rate 30 % 30 % 30 % Increases (decreases) resulting from: Tax rate differences 39 78 191 Disallowable expenditures (4 ) (17 ) (10 ) Valuation allowances (89 ) (1,577 ) (259 ) Anadarko litigation settlement — 1,341 — State NOL limitations — (15 ) — State rate changes 17 — — Withholding taxes (15 ) (24 ) (59 ) Prior year accruals 3 (2 ) 22 Change in uncertain tax positions — — 6 Foreign exchange — 1 17 Tax credits 1 2 8 Branch taxation 1 4 6 Other, net 2 (1 ) — Effective tax rate (15 )% (180 )% (48 )% Due to the changes in our state apportionment factors, statutory rate changes in certain states in which we operate, and the acquisition of the Alkali entities, our overall effective state tax rate changed during 2015. This change resulted in an increase to our state deferred tax assets and is reflected within the state rate changes line above. The increased tax benefit is offset by a valuation allowance and results in no impact to the consolidated provision for income taxes for the year ended December 31, 2015. The effective tax rate for each of 2015, 2014, and 2013 differs from the Australian statutory rate of 30%. Historically, the differences were primarily due to valuation allowances, income in foreign jurisdictions taxed at rates lower than 30%, and withholding tax accruals on interest income. Additionally, the effective tax rate for 2014 is impacted by $58 million and $255 million, respectively, due to increases to full valuation allowances in The Netherlands and Australia. During 2014, the Anadarko Litigation settlement of $5.2 billion provided us with additional deferred tax assets of $2.0 billion, which were offset by full valuation allowances in the United States of $2.0 billion. As a result of an ownership change on June 15, 2012, our ability to use federal losses was not impacted; however, due to state apportionment impacts and carryforward periods, our state losses were limited. This limitation which was recorded in 2014 resulted in the loss of $23 million of deferred tax assets but was fully offset by a reduction of the related valuation allowances. The statutory tax rates on income earned in South Africa (28% for limited liability companies), The Netherlands (25% for corporations), and the United Kingdom (20.25% for corporations and limited liability companies and not applicable for certain limited liability partners) are lower than the Australian statutory rate of 30%. The statutory tax rate, applied against losses in the United States (35% for corporations), is higher than the Australian statutory rate of 30%. Also, we continue to maintain a full valuation allowance in Australia, The Netherlands, and the United States. Our current year tax expense is primarily related to withholding tax accruals. As a result of the Alkali Transaction, we expect to offset a portion of our previously existing US tax attributes with income generated by the Alkali entities. This expectation, however, does not change our overall judgement regarding the utilization of existing deferred tax assets. Net deferred tax assets (liabilities) at December 31, 2015 and 2014 were comprised of the following: December 31, 2015 2014 Deferred tax assets: Net operating loss and other carryforwards $ 1,614 $ 626 Property, plant and equipment 343 324 Reserves for environmental remediation and restoration 23 26 Obligations for pension and other employee benefits 86 87 Investments 25 28 Grantor trusts 1,231 2,118 Inventory 6 15 Interest 445 314 Other accrued liabilities 11 11 Unrealized foreign exchange losses 3 2 Other 15 14 Total deferred tax assets 3,802 3,565 Valuation allowance associated with deferred tax assets (3,576 ) (3,345 ) Net deferred tax assets 226 220 Deferred tax liabilities: Property, plant and equipment (222 ) (266 ) Intangibles (96 ) (103 ) Inventory (8 ) (10 ) Unrealized foreign exchange gains (40 ) (25 ) Other (3 ) (7 ) Total deferred tax liabilities (369 ) (411 ) Net deferred tax asset (liability) $ (143 ) $ (191 ) Balance sheet classifications: Deferred tax assets — current $ — $ 13 Deferred tax assets — long-term — 9 Deferred tax liabilities — current — (9 ) Deferred tax liabilities — long-term (143 ) (204 ) Net deferred tax asset (liability) $ (143 ) $ (191 ) The net deferred tax assets (liabilities) 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. Additionally, as a result of the resolution of the Anadarko Litigation of $5.2 billion during 2014, we recorded additional deferred tax assets of $2.0 billion. This increase was fully offset by valuation allowances. During 2015, the U.S. net operating loss increased as the grantor trusts spent a portion of the funds received from the litigation. In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (ASU 2015-17), “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The standard requires that deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and noncurrent. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax assets and liabilities. We early adopted ASU 2015-17 during the fourth quarter of 2015 on a prospective basis. Accordingly, we classified all deferred taxes as noncurrent at December 31, 2015, but did not adjust the balances presented at December 31, 2014. The adoption did not have a material effect on our consolidated financial statements. During 2015 and 2014, the total changes to the valuation allowance were an increase of $231 million and $2.4 billion, respectively. The increase during 2015 was primarily related to valuation allowance offsets to the deferred tax benefits from current year book losses. The table below sets forth the changes, by jurisdiction: December 31, 2015 2014 Australia $ 112 $ 255 United States 114 2,058 The Netherlands 6 50 South Africa (1 ) — Total increase in valuation allowances $ 231 $ 2,363 At December 31, 2015, we maintain full valuation allowances related to the total net deferred tax assets in Australia, the United States, and The Netherlands, as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. Future provisions for income taxes will include no tax benefits with respect to losses incurred and tax expense only to the extent of current state tax payments until the valuation allowances are eliminated. Additionally, we have valuation allowances against specific tax assets in South Africa. These conclusions were reached by the application of ASC 740, Income Taxes An ownership change occurred during 2012, as a result of the Exxaro Transaction. These ownership changes resulted in a limitation under IRC Sections 382 and 383 related to U.S. net operating losses. We do not expect that the application of these net limitations will have any material effect on our U.S. federal income tax liabilities; however, for 2014, we reduced our state net operating loss carryforwards and the related deferred tax benefits. The loss of these benefits is offset by a corresponding reduction in the valuation allowances. The deferred tax assets generated by tax loss carryforwards in Australia, the United States, and The Netherlands have been fully offset by valuation allowances. The expiration of these carryforwards at December 31, 2015 is shown below. The Australian and South African tax loss carryforwards do not expire. Australia U.S. Federal U.S. State Other Tax Loss Carryforwards Total 2016 $ — $ — $ 8 $ — $ 8 2017 — — — — — 2018 — — 21 — 21 2019 — — 1 — 1 2020 — — 20 — 20 Thereafter — 3,534 3,527 189 7, 250 No Expiration 499 — — 16 515 Total tax loss carryforwards $ 499 $ 3,534 $ 3,577 $ 205 $ 7,815 At December 31, 2015, Tronox Limited had foreign subsidiaries with undistributed earnings. Although we would not be subject to income tax on these earnings, amounts totaling $147 million could be subject to withholding tax if distributed. Tronox Incorporated had certain foreign subsidiaries with undistributed earnings totaling $165 million. We have made no provision for deferred taxes for either Tronox Limited or Tronox Incorporated related to these undistributed earnings because they are considered to be indefinitely reinvested outside of the parents’ taxing jurisdictions. A reconciliation of the beginning and ending amounts of unrecognized tax benefits for 2015 and 2014 is as follows: Year Ended December 31, 2015 2014 Balance at January 1 $ 1 $ 1 Reductions for tax positions related to prior years — — Balance at December 31 $ 1 $ 1 Included in the balance at December 31, 2015 and 2014, were tax positions of $1 million and $1 million, respectively, for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility. None of these net benefits, if recognized, would impact the effective income tax rate. As a result of potential settlements, it is reasonably possible that our gross unrecognized tax benefits from timing differences may decrease within the next twelve months by $1 million. During 2015, 2014, and 2013, we did not recognize any gross interest or penalties in “Income tax benefit (provision)” in the Consolidated Statements of Operations related to unrecognized tax benefits. At December 31, 2015 and 2014, we had no remaining accruals for the gross payment of interest and penalties related to unrecognized tax benefits, and the noncurrent liability section of the Consolidated Balance Sheets reflected $1 million and $1 million, respectively, as the reserve for uncertain tax positions. Our Australian returns are closed through 2011. However, under Australian tax laws, transfer pricing issues have no limitation period. Our U.S. returns are closed for years through 2011, with the exception of an amendment filed for the 2007 tax year. Our Netherlands returns are closed through 2012. In accordance with the Transaction Agreement, we are not liable for income taxes of the acquired companies with respect to periods prior to the Transaction Date. 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. Anadarko Litigation On January 23, 2015, Anadarko Petroleum Corp. (“Anadarko”) paid $5.2 billion, including approximately $65 million of accrued interest, pursuant to the terms of a settlement agreement with Tronox Incorporated. We did not receive any portion of the settlement amount. Instead, 88% of the $5.2 billion went to trusts and other governmental entities for the remediation of polluted sites by Kerr-McGee Corporation (“Kerr-McGee”). The remaining 12% was distributed to a tort trust to compensate individuals injured as a result of Kerr-McGee’s environmental failures. We received a private letter ruling from the U.S. Internal Revenue Service confirming that the trusts that held the claims against Anadarko are grantor trusts of Tronox Incorporated solely for federal income tax purposes. As a result, we believe we are entitled to tax deductions equal to the amount spent by the trusts to remediate environmental matters and to compensate the injured individuals. These deductions will accrue over the life of the trusts as the $5.2 billion is spent. We believe that these expenditures and the accompanying tax deductions may continue for decades. At December 31, 2014, we had recorded deferred tax assets of $2.0 billion related to the $5.2 billion of expected future tax deductions from trust expenditures. These deferred tax assets were fully offset by valuation allowances. At December 31, 2015, approximately $2.4 billion of the trust expenditures expected from the litigation proceeds have been incurred.

Consequently, for 2015, 2014, and 2013, the two-class method did not have an effect on our net loss per ordinary share calculation, and as such, dividends paid during the year did not impact this calculation. (2) Net loss per ordinary share amounts were calculated from exact, not rounded net loss and share information. In computing diluted net loss per share under the two-class method, we considered potentially dilutive shares. Anti-dilutive shares not recognized in the diluted net loss per share calculation were as follows: December 31, 2015 December 31, 2014 December 31, 2013 Shares Average Exercise Price Shares Average Exercise Price Shares Average Exercise Price Options 2,189,967 $ 21.15 2,560,875 $ 21.14 2,094,771 $ 20.63 Series A Warrants (1) 1,354,529 $ 9.63 1,273,917 $ 11.04 1,850,814 $ 11.52 Series B Warrants (1) 1,833,834 $ 10.63 1,715,986 $ 12.19 2,409,404 $ 12.71 Restricted share units 1,494,027 $ 23.04 875,776 $ 22.17 303,324 $ 21.08 (1) Series A Warrants and Series B Warrants were converted into Class A Shares at December 31, 2015, 2014, and 2013 using a rate of 5.66, 5.29, and 5.18, respectively.

Fair Value Measurement [Abstract]
Fair Value Measurement	9. Fair Value Measurement For financial instruments that are subsequently measured at fair value, the fair value measurement is grouped into levels. See Note 2. At December 31, 2015 and 2014, the only financial instrument measured at fair value was the environmental rehabilitation trust, which amounted to $12 million and $17 million, respectively, and was categorized as Level 2. See Note 17. The carrying amounts for cash and cash equivalents, accounts receivable, other current assets, accounts payable, short-term debt, and other current liabilities approximate their fair value because of the short-term nature of these instruments. Our debt is recorded at historical amounts. At December 31, 2015 and 2014, the fair value of the Term Loan was $1.3 billion and $1.5 billion, respectively. At December 31, 2015 and 2014, the fair value of the Senior Notes due 2020 was $520 million and $903 million, respectively. At December 31, 2015, the fair value of the Senior Notes due 2022 was $347 million. We determined the fair value of the Term Loan, the Senior Notes due 2020 and the Senior Notes due 2022 using quoted market prices. The fair value hierarchy for the Term Loan, the Senior Notes due 2020 and the Senior Notes due 2022 is a Level 1 input. Balances outstanding under our UBS Revolver are carried at contracted amounts, which approximate fair value based on the short term nature of the borrowing and the variable interest rate. The fair value hierarchy for our UBS Revolver is a Level 2 input.

Debt [Abstract]
Debt	16. Debt Short-term debt consisted of the following: December 31, 2015 2014 UBS Revolver $ 150 $ — Short-term debt (1) $ 150 $ — (1) Average effective interest rate of 3.5% during 2015. UBS Revolver We have a global senior secured asset-based syndicated revolving credit facility with UBS AG (“UBS”) with a maturity date of June 18, 2017 (the “UBS Revolver”). Through March 31, 2015, the UBS Revolver provided us with a committed source of capital with a principal borrowing amount of up to $300 million, subject to a borrowing base. Balances due under the UBS Revolver are carried at contracted amounts, which approximate fair value based on the short term nature of the borrowing and the variable interest rate. On April 1, 2015, in connection with the Alkali Transaction, we entered into an amended and restated asset-based revolving syndicated facility agreement with UBS, which provides for up to $500 million of revolving credit lines, with a $85 million sublimit for letters of credit with a new maturity that is the earlier of the date which is five (5) years after the closing date and the date which is 3 months prior to the maturity of the Term Loan Agreement; provided that in no event shall the Revolving Maturity be earlier than June 18, 2017. Availability of revolving credit loans and letters of credit are subject to a borrowing base. Borrowings bear interest at our option, at either a base rate or an adjusted London Interbank Offered Rate (“LIBOR”) as the greatest of (a) the Administrative Agent’s prime rate, (b) the Federal funds effective rate plus 0.50% and (c) the adjusted LIBOR for a one-month period plus 1.00%. The applicable margin ranges from 0.50% to 1.00% for borrowings at the base rate and from 1.50% to 2.00% for borrowings at the adjusted LIBOR, in each case, based on the average daily borrowing availability. On April 1, 2015, we borrowed $150 million against the UBS Revolver, which was outstanding at December 31, 2015. At December 31, 2014, there were no outstanding borrowings on the UBS Revolver. We had no drawdowns or repayments on the UBS Revolver during 2014. During 2015, we incurred $2 million of deferred debt issuance costs related to the UBS Revolver, which were capitalized and included in “Other long-term assets” in the Consolidated Balance Sheet at December 31, 2015. At December 31, 2015 and 2014, our amount available to borrow was $217 million and $276 million, respectively. ABSA Revolving Credit Facility We have a R1.3 billion (approximately $84 million at December 31, 2015) revolving credit facility with ABSA Bank Limited (“ABSA”) acting through its ABSA Capital Division with a maturity date of June 14, 2017 (the “ABSA Revolver”). The ABSA Revolver bears interest at (i) the base rate (defined as one month JIBAR, which is the mid-market rate for deposits in South African Rand for a period equal to the relevant period which appears on the Reuters Screen SAFEY Page alongside the caption YLD) as of 11h00 Johannesburg time on the first day of the applicable period, plus (ii) the Margin, which is 3.9%. During 2015 and 2014, we had no drawdowns or repayments on the ABSA Revolver. During 2013, we had no drawdowns and a repayment of $30 million. The weighted average interest rate was 8.5% during 2013. At December 31, 2015 and 2014, there were no outstanding borrowings on the ABSA Revolver. Long-term debt, net of an unamortized discount, consisted of the following: Original Principal Annual Interest Rate Maturity Date December 31, 2015 December 31, 2014 Term Loan, net of unamortized discount (1) $ 1,500 Variable 3/19/2020 $ 1,454 $ 1,468 Senior Notes due 2020 $ 900 6.375 % 8/15/2020 900 900 Senior Notes due 2022 $ 600 7.50 % 3/15/2022 600 — Co-generation Unit Financing Arrangement $ 16 6.50 % 2/1/2016 1 3 Lease financing 16 22 Total borrowings 2,971 2,393 Less: Long-term debt due within one year (16 ) (18 ) Long-term debt $ 2,955 $ 2,375 (1) Average effective interest rate of 4.7% and 4.6% during 2015 and 2014, respectively. At December 31, 2015, the scheduled maturities of our long-term debt were as follows: Total Borrowings 2016 $ 16 2017 16 2018 16 2019 16 2020 2,301 Thereafter 612 Total 2,977 Remaining accretion associated with the Term Loan (6 ) Total borrowings $ 2,971 Term Loan On March 19, 2013, we, along with our wholly owned subsidiary, Tronox Pigments (Netherlands) B.V., and certain of our subsidiaries named as guarantors, entered into a Second Amended and Restated Credit and Guaranty Agreement (the “Second Agreement”) with Goldman Sachs Bank USA, as administrative agent and collateral agent, and Goldman Sachs Bank USA, UBS Securities LLC, Credit Suisse Securities (USA) LLC and RBC Capital Markets, as joint lead arrangers, joint bookrunners and co-syndication agents. Pursuant to the Second Agreement, we obtained a $1.5 billion senior secured term loan (the “Term Loan”). The Term Loan was issued net of an original issue discount. At December 31, 2015 and 2014, the unamortized discount was $6 million and $7 million, respectively. We made principal repayments during 2015 and 2014 of $15 million and $17 million, respectively. On April 23, 2014, we, along with our wholly owned subsidiary, Tronox Pigments (Netherlands) B.V., and certain of our subsidiaries named as guarantors, entered into a Third Amendment to the Credit and Guaranty Agreement (the “Third Agreement”) with the lender parties thereto and Goldman Sachs Bank USA, as administrative agent, which amends the Second Agreement. The Third Agreement provides for the re-pricing of the Term Loan by replacing the existing definition of “Applicable Margin” with a grid pricing matrix dependent upon our public corporate family rating as determined by Moody’s and Standard & Poor’s (with the interest rate under the Third Agreement remaining subject to Eurodollar Rate and Base Rate floors, as defined in the Third Agreement). Pursuant to the Third Agreement, based upon our current public corporate family rating by Moody’s and Standard & Poor’s, the current interest rate per annum is 350 basis points plus LIBOR (subject to a LIBOR floor of 1% per annum) compared to 350 basis points plus LIBOR (subject to a LIBOR floor of 1% per annum) in the Second Agreement. The Third Agreement also amended certain provisions of the Second Agreement to permit us and certain of our subsidiaries to obtain new cash flow revolving credit facilities in place of our existing asset based revolving credit facility. The maturity date under the Second Agreement and all other material terms of the Second Agreement remain the same under the Third Agreement. The Third Agreement resulted in a modification for certain lenders and an extinguishment for other lenders. Accordingly, we recognized an $8 million charge during 2014 for the early extinguishment of debt resulting from the write-off of deferred debt issuance costs and discount on debt associated with the Second Agreement. We also paid $2 million of new debt issuance costs related to the Third Agreement during 2014, which were recorded in “Other long-term assets” in the Consolidated Balance Sheets. Senior Notes due 2020 On August 20, 2012, our wholly owned subsidiary, Tronox Finance LLC (“Tronox Finance”), completed a private placement offering of $900 million aggregate principal amount of senior notes at par value (the “Senior Notes due 2020”). The Senior Notes due 2020 bear interest semiannually at a rate equal to 6.375%, and are fully and unconditionally guaranteed on a senior, unsecured basis by us and certain of our subsidiaries. The Senior Notes due 2020 were initially offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act. On September 17, 2013, Tronox Finance issued $900 million in aggregate principal amount of registered 6.375% Senior Notes due 2020 in exchange for its then existing $900 million in aggregate principal amount of its 6.375% Senior Notes due 2020. The Senior Notes due 2020 are guaranteed by Tronox and certain of its subsidiaries. See Note 26. Senior Notes due 2022 On March 6, 2015, Evolution Escrow Issuer LLC (“Evolution”), a special purpose limited liability company organized under the laws of Delaware, was formed. Evolution was wholly owned by Stichting Evolution Escrow, a Dutch foundation not affiliated with the Company. On March 19, 2015, Evolution closed an offering of $600 million aggregate principal amount of its 7.50% Senior Notes due 2022 (the “Senior Notes due 2022”). The Senior Notes due 2022 were offered and sold by Evolution in reliance on an exemption pursuant to Rule 144A and Regulation S under the Securities Act. The Senior Notes due 2022 were issued under an Indenture, dated as of March 19, 2015 (the “Indenture”), between Evolution and Wilmington Trust, National Association (the “Trustee”). On April 1, 2015, in connection with the Alkali Transaction, Evolution merged with and into Tronox Finance, Tronox Finance assumed the obligations of Evolution under the Indenture and the Senior Notes due 2022, and the proceeds from the offering were released to us to partially pay the purchase price for the Alkali Transaction. We and certain of our subsidiaries entered into a supplemental indenture (the “First Supplemental Indenture”), by and among us, Tronox Finance, the guarantors party thereto, and the Trustee, pursuant to which we and such subsidiaries became guarantors of the Senior Notes due 2022 under the Indenture. The Senior Notes due 2022 have not been registered under the Securities Act, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. Debt issuance costs related to the Senior Notes due 2022 of $13 million were capitalized and included in “Other long-term assets” in the Consolidated Balance Sheets at December 31, 2015. The Indenture and the Senior Notes due 2022 provide, among other things, that the Senior Notes due 2022 are senior unsecured obligations of Tronox Finance. Interest is payable on March 15 and September 15 of each year beginning on September 15, 2015 until their maturity date of March 15, 2022. The terms of the Indenture, among other things, limit, in certain circumstances, the ability of us to: incur certain additional indebtedness and issue preferred stock; make certain dividends, distributions, investments and other restricted payments; sell certain assets; incur liens; agree to any restrictions on the ability of certain subsidiaries to make payments to the Company; consolidate or merge with or into, or sell substantially all of our assets to, another person; enter into transactions with affiliates; and enter into new lines of business. As of December 31, 2015 we had $217 million available under the $500 million UBS Revolver, $84 million available under the ABSA Revolver and $229 million in cash and cash equivalents. In the next twelve months, we expect that our operations and available borrowings under our revolving credit agreements will provide sufficient cash to fund our operating expenses, capital expenditures, interest payments, debt repayments, and dividends. Lease Financing We have capital lease obligations in South Africa, which are payable through 2031 at a weighted average interest rate of approximately 14%. At December 31, 2015 and 2014, such obligations had a net book value of assets recorded under capital leases aggregating $14 million and $20 million, respectively. During 2015, 2014, and 2013 we made principal payments of less than $1 million for all periods. At December 31, 2015, future minimum lease payments, including interest, were as follows: Principal Repayments Interest Total Payments 2016 $ 1 $ 2 $ 3 2017 1 2 3 2018 1 2 3 2019 1 2 3 2020 1 2 3 Thereafter 11 12 23 Total 16 22 38 Bridge Facility In connection with the Alkali Transaction, we entered into a $600 million senior unsecured bridge facility (the “Bridge Facility”). The Bridge Facility was not utilized and terminated with the completion of the Alkali Transaction. During 2015, we incurred $8 million of financing fees related to the Bridge Facility, which were included in “Interest and debt expense, net” in the Consolidated Statements of Operations. Debt Covenants At December 31, 2015, we had financial covenants in the UBS Revolver, the ABSA Revolver and the Term Loan; however, only the ABSA Revolver had a financial maintenance covenant that applies to local operations and only when the ABSA Revolver is drawn upon. The Term Loan and the UBS Revolver are subject to an intercreditor agreement pursuant to which the lenders’ respective rights and interests in the security are set forth. We were in compliance with all our financial covenants as of and for the year ended December 31, 2015. Interest and Debt Expense, Net Interest and debt expense, net consisted of the following: Year Ended December 31, 2015 2014 2013 Interest on debt $ 160 $ 124 $ 122 Amortization of deferred debt issuance costs and discounts on debt 11 10 9 Bridge Facility 8 — — Other 3 2 4 Capitalized interest (6 ) (3 ) (5 ) Total interest and debt expense, net $ 176 $ 133 $ 130 In connection with obtaining debt, we incurred debt issuance costs, which are being amortized through the respective maturity dates using the effective interest method. At December 31, 2015 and 2014, we had $49 million and $44 million, respectively, of deferred debt issuance costs, which were recorded in “Other long-term assets” in the Consolidated Balance Sheets.

Activity related to asset retirement obligations was as follows: Year Ended December 31, 2015 2014 Beginning balance $ 90 $ 96 Additions 3 5 Accretion expense 5 4 Remeasurement/translation (12 ) (9 ) Changes in estimates, including cost and timing of cash flows (3 ) — Settlements/payments (2 ) (6 ) Ending balance $ 81 $ 90 Current portion included in “Accrued liabilities” $ 4 $ 5 Noncurrent portion included in “Asset retirement obligations” $ 77 $ 85 We used the following assumptions in determining asset retirement obligations at December 31, 2015: inflation rates between 2.5% - 5.5% per year; credit adjusted risk-free interest rates between 3.2% -16.7%; the life of mines between 21- 35 years and the useful life of assets of between 1-24 years. Environmental Rehabilitation Trust In accordance with applicable regulations, we have established an environmental rehabilitation trust for the prospecting and mining operations in South Africa, which receives, holds, and invests funds for the rehabilitation or management of asset retirement obligations. The trustees of the fund are appointed by us, and consist of sufficiently qualified employees capable of fulfilling their fiduciary duties. At December 31, 2015 and 2014, the environmental rehabilitation trust assets were $12 million and $17 million, respectively, which were recorded in “Other long-term assets” in the Consolidated Balance Sheets.

Derivative Instruments [Abstract]
Derivative Instruments	18. Derivative Instruments We manufacture and market our products in a number of countries throughout the world and, as a result, are exposed to changes in foreign currency exchange rates, particularly in South Africa, Australia, and The Netherlands. Costs in South Africa and Australia are primarily incurred in local currencies, while the majority of revenues are in U.S. dollars. In Europe, the majority of revenues and costs are in the local currency. This leaves us exposed to movements in the South African Rand and the Australian dollar versus the U.S. dollar. In order to manage this risk, we enter into currency forward contracts to buy and sell foreign currencies as “economic hedges” for these foreign currency transactions. Our currency forward contracts were not designated for hedge accounting treatment under ASC 815, Derivatives and Hedging

Subject to further adjustment, the maximum number of shares which may be the subject of awards (inclusive of incentive options) is 12,781,225 Class A Shares. Restricted Shares During 2015, we granted restricted shares which vest ratably over a three-year period. These awards are classified as equity awards, and are accounted for using the fair value established at the grant date. The following table presents a summary of activity for 2015: Number of Shares Weighted Average Grant Date Fair Value Outstanding, January 1, 2015 635,295 $ 22.82 Granted 66,108 22.60 Vested (197,545 ) 22.07 Forfeited (130,580 ) 26.14 Outstanding, December 31, 2015 373,278 $ 22.02 Expected to vest, December 31, 2015 372,713 $ 22.02 At December 31, 2015, there was $1 million of unrecognized compensation expense related to nonvested restricted shares, adjusted for estimated forfeitures, which is expected to be recognized over a weighted-average period of 1.3 years. The weighted-average grant-date fair value of restricted shares granted during 2015, 2014 and 2013 was $22.60 per share, $22.17 per share, and $21.18 per share, respectively. The total fair value of restricted shares that vested during 2015, 2014 and 2013 was $4 million, $8 million, and $2 million, respectively. Restricted Share Units (“RSUs”) During 2015, we granted RSUs which have time and/or performance conditions. Both the time-based awards and the performance-based awards are classified as equity awards. The time-based awards vest ratably over a three-year period, and are valued at the weighted average grant date fair value. The performance-based awards cliff vest at the end of the three years. Included in the performance-based awards are RSUs for which vesting is determined by a Total Stockholder Return (“TSR”) calculation over the applicable measurement period. The TSR metric is considered a market condition for which we use a Monte Carlo simulation to determine the grant date fair value. The following table presents a summary of activity for 2015: Number of Shares Weighted Average Grant Date Fair Value Outstanding, January 1, 2015 875,776 $ 22.17 Granted 948,487 23.47 Vested (265,172 ) 21.69 Forfeited (65,064 ) 22.96 Outstanding, December 31, 2015 1,494,027 $ 23.04 Expected to vest, December 31, 2015 1,460,857 $ 23.03 At December 31, 2015, there was $17 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 1.7 years. The weighted-average grant-date fair value of restricted share units granted during 2015, 2014 and 2013 was $23.47 per share, $22.37 per share, and $21.06 per share, respectively. The total fair value of RSUs that vested during 2015, 2014 and 2013 was $6 million, $3 million and less than $1 million, respectively. Options During the 2015, we granted options to purchase Class A Shares, which vest ratably over a three-year period and have a ten-year term. The following table presents a summary of activity for 2015: Number of Options Weighted Average Exercise Price Weighted Average Contractual Life (years) Intrinsic Value Outstanding, January 1, 2015 2,560,875 $ 21.14 7.88 $ 8 Granted 2,380 22.69 Exercised (141,473 ) 19.37 Forfeited (231,815 ) 22.13 Expired — — Outstanding, December 31, 2015 2,189,967 $ 21.15 7.39 $ — Expected to vest, December 31, 2015 906,337 $ 20.78 7.71 $ — Exercisable, December 31, 2015 1,275,676 $ 21.41 7.16 $ — The aggregate intrinsic values in the table represent the total pre-tax intrinsic value (the difference between our share price at the indicated dates and the options’ exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at the end of the year. The amount will change based on the fair market value of our stock. Total intrinsic value of options exercised during 2015, 2014 and 2013 was less than $1 million, $2 million, and less than $1 million, respectively. We issue new shares upon the exercise of options. During 2015 and 2014, we received $3 million and $6 million, respectively, in cash for the exercise of stock options. At December 31, 2015, unrecognized compensation expense related to options, adjusted for estimated forfeitures, was $3 million, which is expected to be recognized over a weighted-average period of 1 year. During the 2015 and 2014, we granted 2,380 and 915,988 options, respectively, with a weighted average grant date fair value of $7.04 and $8.19, respectively. Fair value is determined on the grant date using the Black-Scholes option-pricing model and is recognized in earnings on a straight-line basis over the employee service period of three years, which is the vesting period. The assumptions used in the Black-Scholes option-pricing model on the grant date were as follows: January 5, 2015 Number of options granted 2,380 Fair market value and exercise price $ 22.69 Risk-free interest rate 1.83 % Expected dividend yield 4.41 % Expected volatility 48 % Maturity (years) 10 Expected term (years) 6 Per-unit fair value of options granted $ 7.04 The fair value is based on the closing price of our Class A Shares on the grant date. The risk-free interest rate is based on U.S. Treasury Strips available with a maturity period consistent with the expected life assumption. The expected volatility assumption is based on historical price movements of our peer group. T-Bucks Employee Participation Plan (“T-Bucks EPP”) During 2012, we established the T-Bucks EPP for the benefit of certain qualifying employees of our South African subsidiaries. We funded the T-Bucks Trust (the “Trust”) with R124 million (approximately $15 million), which was used to acquire Class A Shares. Additional contributions may be made in the future at the discretion of the Board. The T-Bucks EPP is classified as an equity-settled shared-based payment plan, whereby participants were awarded share units in the Trust, which entitles them to receive Class A Shares upon completion of the vesting period on May 31, 2017. Participants are entitled to receive dividends on the shares during the vesting period. Forfeited shares are retained by the Trust, and are allocated to future participants. Compensation costs are recognized over the vesting period using the straight-line method. During 2012, the Trust purchased 548,234 Class A Shares at $25.79 per share, which was the fair value on the date of purchase. The balance at both December 31, 2015 and 2014 was 548,234 shares. Long-Term Incentive Plan We have a long-term incentive plan (the “LTIP”) for the benefit of certain qualifying employees of Tronox subsidiaries in South Africa and Australia. The LTIP is classified as a cash settled compensation plan, and is re-measured to fair value at each reporting date. At December 31, 2015 and 2014, the LTIP plan liability was less than $1 million and $1 million, respectively.

Pension and Other Postretirement Healthcare Benefits [Abstract]
Pension and Other Postretirement Healthcare Benefits	23. Pension and Other Postretirement Healthcare Benefits We sponsor two noncontributory defined benefit retirement plans, the qualified retirement plan and Alkali qualified retirement plan in the United States, a defined benefit retirement plan in The Netherlands, a collective defined contribution plan in The Netherlands, and a South Africa postretirement healthcare plan. U.S. Plans Qualified Retirement Plan Postretirement Healthcare Plan Tronox Alkali Qualified Retirement Plan Foreign Plans Netherlands Plan — On January 1, 2007, we established the TDF-Botlek Pension Fund Foundation (the “Netherlands Plan”) to provide defined pension benefits to qualifying employees of Tronox Pigments (Holland) B.V. and its related companies. During the fourth quarter of 2014, in response to the tax and pension legislation changes in The Netherlands, our benefit committee approved to end future benefit accruals under The Netherlands Plan and replaced it with a multiemployer plan effective January 1, 2015. As a result of this decision, effective from January 1, 2015, benefit contributions commenced under the multiemployer plan while The Netherlands Plan became effectively “frozen”. This action ended future benefit accrual for participants under the current plan, resulting in a curtailment gain of $3 million, which was recognized in “Other income (expense), net” in the Consolidated Statements of Operations during 2014. Such amounts had previously been recognized as unamortized prior service costs in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. The changes also resulted in a reduction of the projected benefit obligation by $27 million, which was recognized in “Accumulated other comprehensive income” in the Consolidated Balance Sheets at December 31, 2014. Netherlands Collective Contribution Plan — Effective January 1, 2015, we ceased offering benefits under the Netherlands Plan to qualifying employees and established a multiemployer plan, the collective contribution plan (“CDC plan”). 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 20.6% of the participants’ pensionable salaries into a pooled fund administered by the industrywide Pension Fund for Graphical Industry (“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 new plan is limited to the fixed percentage contribution we make each year. That is, investment risks, mortality risks and other actuarial risks typically associated with a defined benefit plan are borne by the employees. Additionally, 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, 2015. The CDC disclosures provided herein are based on the fund’s 2014 annual report, which is the most recently available public information. On the basis of the total plan assets and accumulated benefit obligation information in the plan’s annual report, the zone status was green as of December 31, 2014. 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, 2015, 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 2015 2014 FIP/RP Pending/ Implemented 2015 2014 2013 Surcharge Imposed Expiration date of Collective- Bargaining Agreement PGB NA NA Green No $ 4 NA NA No 12/31/2019 On the basis of the information available in the plan’s 2014 annual report, our contribution does not constitute more than 5 percent of the total contribution to the plan by all participants. During 2015, the fund did not impose any surcharge on us.

At December 31, 2015, our qualified retirement plan was in an underfunded status of $116 million. As a result, we have a projected minimum funding requirement of $18 million for 2015, which will be payable in 2016.

We concluded that the updated table represented our best estimate of mortality. This change in assumption resulted in an increase in our projected benefit obligation of $36 million as compared to December 31, 2013. In 2015, the mortality improvement scale that had been used in the 2014 mortality table was updated by the Society of Actuaries to reflect actual experience in mortality rates. We updated our mortality assumption accordingly resulting in a decrease of $8 million to our projected benefit obligation as compared to December 31, 2014. The following weighted-average assumptions were used in determining the actuarial present value of the South African Postretirement Healthcare Plan: 2015 2014 2013 Discount rate 10.94 % 9.16 % 10.14 % Expected Return on Plan Assets Discount Rate The discount rates selected for estimating the actuarial present value of the benefit obligation of Alkali plan was 5.0% as of December 31, 2015 which was selected based on the results of a cash flow matching analysis, which projected the expected cash flows of the plan using Aon Hewitt AA Above Median yield curve developed from a U.S. currency corporate bonds with at least $250 million outstanding. The discount rates selected for estimating the actuarial present value of the benefit obligation of The Netherlands plan was 2.25% both as of December 31, 2015 and 2014, which is based on long-term Euro corporate bond index rates that correlate with anticipated cash flows associated with future benefit payments.

The committee maintains an investment policy stating the guidelines for the performance and allocation of plan assets, performance review procedures and updating of the policy. At least annually, the U.S. plan’s asset allocation guidelines are reviewed in light of evolving risk and return expectations. Substantially all of the plan’s assets are invested with nine equity fund managers, three fixed-income fund managers and one money-market fund manager. To control risk, equity fund managers are prohibited from entering into the following transactions, (i) investing in commodities, including all futures contracts, (ii) purchasing letter stock, (iii) short selling, and (iv) option trading. In addition, equity fund managers are prohibited from purchasing on margin and are prohibited from purchasing Tronox securities. Equity managers are monitored to ensure investments are in line with their style and are generally permitted to invest in U.S. common stock, U.S. preferred stock, U.S. securities convertible into common stock, common stock of foreign companies listed on major U.S. exchanges, common stock of foreign companies listed on foreign exchanges, covered call writing, and cash and cash equivalents. Fixed-income fund managers are prohibited from investing in (i) direct real estate mortgages or commingled real estate funds, (ii) private placements above certain portfolio thresholds, (iii) tax exempt debt of state and local governments above certain portfolio thresholds, (iv) fixed income derivatives that would cause leverage, (v) guaranteed investment contracts, and (vi) Tronox securities. They are permitted to invest in debt securities issued by the U.S. government, its agencies or instrumentalities, commercial paper rated A3/P3, FDIC insured certificates of deposit or bankers’ acceptances and corporate debt obligations. Each fund manager’s portfolio has an average credit rating of A or better. The Alkali plan is administered by a board-appointed committee that has fiduciary responsibility for the plan’s management. The committee is responsible for the oversight and management of the plan’s investments. The committee maintains an investment policy that provides guidelines for selection and retention of investment managers or funds, allocation of plan assets and performance review procedures and updating of the policy. At least annually, the Alkali plan’s asset allocation guidelines are reviewed in light of evolving risk and return expectations. The objective of the committee’s investment policy is to manage the plan assets in such a way that will allow for the on-going payment of the Company’s obligation to the beneficiaries. To meet this objective, the committee has structured a portfolio that will provide liquidity to meet the plan benefit payments and expense payable from the plan under ERISA and manage the plan asset in a liability framework. To provide adequate liquidity and control risk, the investment policy sets our broad investment guidelines that permit investment managers and funds to invest in liability-hedging assets to control the plan’s surplus volatility. This includes investment in high-quality, investment grade bonds with durations that approximate the durations of the liabilities. Fixed income portfolio managers are permitted to use fixed income derivative contracts to achieve general portfolio objectives in accordance with the risk management and internal control procedures agreed between the manager and the committee’s advisor. The overall performance of the liability-hedging assets will be determined primarily by how they track the investable custom liability-hedging mandate they are designed to hedge. Cash equivalents can he held to meet the benefits obligations of the plan and to pay fees. The plan’s cash equivalents investments could be invested in a diversified mix of high-quality, short-term debt securities, including commercial paper, bankers’ acceptance, certificates of deposits and US government obligations. Investment in return seeking assets is prohibited. The Netherlands plan is administered by a pension committee representing the employer, the employees, and the pensioners. The pension committee has six members, whereby three members are elected by the employer, two members are elected by the employees and one member is elected by the pensioners, and each member has one vote. The pension committee meets at least quarterly to discuss regulatory changes, asset performance, and asset allocation. The plan assets are managed by one Dutch fund manager against a mandate set at least annually by the pension committee. The plan assets are evaluated annually by a multinational benefits consultant against state defined actuarial tests to determine funding requirements.

Defined Contribution Plans U.S. Savings Investment Plan In 2006, we established the U.S. Savings Investment Plan (the “SIP”), a qualified defined contribution plan under section 401(k) of the Internal Revenue Code. 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. During 2015, 2014 and 2013, our matching contribution was 100% of the first 6% of employee contributions. The Board has approved an additional company discretionary contribution of 6% of pay for 2015, 2014 and 2013. The discretionary contribution is subject to approval each year by the Board. 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 SIP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expense associated with our matching contribution to the SIP was $5 million, $4 million, and $3 million during 2015, 2014, and 2013, 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, $4 million, and $4 million during 2015, 2014, and 2013, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations. U.S. Savings Restoration Plan In 2006, we established the U.S. Savings Restoration Plan (the “SRP”), a nonqualified defined contribution plan, for employees whose eligible compensation is expected to exceed the IRS compensation limits for qualified plans. Under the SRP, participants can contribute up to 20% of their annual compensation and incentive. Our matching contribution under the SRP is the same as the SIP. Our matching contribution under this plan vests immediately to plan participants. Contributions under the SRP, including our match, are invested in accordance with the investment options elected by plan participants. Compensation expense associated with our matching contribution to the SRP was $1 million, $1 million, and less than $1 million during 2015, 2014, and 2013, respectively, which was included in “Selling, general and administrative expenses” in the Consolidated Statements of Operations.

Segment Information [Abstract]
Segment Information	25. Segment Information The reportable segments presented below represent our operating segments for which separate financial information is available and which is utilized on a regular basis by our Chief Executive Officer, who is our chief operating decision maker (“CODM”), to assess performance and to allocate resources. Prior to the Alkali Transaction, we had two operating and reportable segments, Mineral Sands and Pigment, based on the way the management team was organized and our CODM monitored performance, aligned strategies, and allocated resources.

Guarantor Condensed Consolidating Financial Statements [Abstract]
Guarantor Condensed Consolidating Financial Statements	26. Guarantor Condensed Consolidating Financial Statements The obligations of Tronox Finance, our wholly-owned subsidiary, under the Senior Notes due 2020 are fully and unconditionally (subject to certain customary circumstances providing for the release of a guarantor subsidiary) guaranteed on a senior unsecured basis, jointly and severally, by Tronox Limited (referred to for purposes of this note only as the “Parent Company”) and each of its current and future restricted subsidiaries, other than excluded subsidiaries, that guarantee any indebtedness of the Parent Company or its restricted subsidiaries (collectively, the “Guarantor Subsidiaries”). The Subsidiary Issuer, Tronox Finance, and each of the Guarantor Subsidiaries are 100% owned, directly or indirectly, by the Parent Company. Our subsidiaries that do not guarantee the Senior Notes due 2020 are referred to as the “Non-Guarantor Subsidiaries.” The guarantor condensed consolidating financial statements presented below presents the statements of operations, statements of comprehensive income (loss), balance sheets and statements of cash flow data for: (i) the Parent Company, the Guarantor Subsidiaries, the Non-Guarantor Subsidiaries, and the subsidiary issuer, on a consolidated basis (which is derived from Tronox historical reported financial information); (ii) the Parent Company, alone (accounting for our Guarantor Subsidiaries, the Non-Guarantor Subsidiaries, and Tronox Finance on an equity basis under which the investments are recorded by each entity owning a portion of another entity at cost, adjusted for the applicable share of the subsidiary’s cumulative results of operations, capital contributions and distributions, and other equity changes); (iii) the Guarantor Subsidiaries alone; (iv) the Non-Guarantor Subsidiaries alone; and (v) the subsidiary issuer, Tronox Finance. The guarantor condensed consolidating financial statements are presented on a legal entity basis, not on a business segment basis. The indentures governing the Senior Notes due 2020 provide for a Guarantor Subsidiary to be automatically and unconditionally released and discharged from its guarantee obligations in certain customary circumstances, including: · Sale or other disposition of such Guarantor Subsidiary’s capital stock or all or substantially all of its assets and all of the indenture obligations (other than contingent obligations) of such Subsidiary Guarantor in respect of all other indebtedness of the Subsidiary Guarantors terminate upon the consummation of such transaction; · Designation of such Guarantor Subsidiary as an “unrestricted subsidiary” under the indenture; · In the case of certain Guarantor Subsidiaries that incur or guarantee indebtedness under certain credit facilities, upon the release or discharge of such Guarantor Subsidiary’s guarantee or incurrence of indebtedness that resulted in the creation of such guarantee, except a discharge or release as a result of payment under such guarantee; · Legal defeasance, covenant defeasance, or satisfaction and discharge of the indenture obligations; · Payment in full of the aggregate principal amount of all outstanding Senior Notes due 2020 and all other obligations under the indenture; or · Release or discharge of the Guarantor Subsidiary’s guarantee of certain other indebtedness.

translation adjustments between the Parent Company and Eliminations column. · Certain financial statement line items have been expanded and reclassifications were made to enhance transparency. These revisions, which we determined are not material to our prior year condensed financial statements or consolidated financial statements based on quantitative and qualitative considerations, did not affect our consolidated financial position, consolidated results of operations or consolidated cash flows.

Quarterly Results of Operations (Unaudited) [Abstract]
Quarterly Results of Operations (Unaudited)	27. Quarterly Results of Operations (Unaudited) The following represents our unaudited quarterly results for the years ended December 31, 2015 and 2014. These quarterly results were prepared in conformity with generally accepted accounting principles and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results, and were of a normal recurring nature. Unaudited quarterly results for 2015: 1 st 2 nd 3 rd 4 th Net sales $ 385 $ 617 $ 575 $ 535 Cost of goods sold 350 593 536 513 Gross profit 35 24 39 22 Net loss (46 ) (118 ) (54 ) (89 ) Net income attributable to noncontrolling interest 3 1 6 1 Net loss attributable to Tronox Limited $ (49 ) $ (119 ) $ (60 ) $ (90 ) Loss per share, basic and diluted $ (0.42 ) $ (1.03 ) $ (0.52 ) $ (0.78 ) Unaudited quarterly results for 2014: 1 st 2 nd 3 rd 4 th Net sales $ 418 $ 490 $ 429 $ 400 Cost of goods sold 393 430 361 346 Gross profit 25 60 68 54 Net income (loss) (54 ) 2 $ (90 ) $ (275 ) Net income attributable to noncontrolling interest 4 2 3 1 Net loss attributable to Tronox Limited $ (58 ) $ — $ (93 ) $ (276 ) Loss per share, basic and diluted $ (0.51 ) $ — $ (0.82 ) $ (2.40 ) The sum of the quarterly per share amounts may not equal the annual per share amounts due to relative changes in the weighted average number of shares used to calculate net income (loss) per share. The $275 million net loss in the fourth quarter of 2014 reflects, in part, a $255 million increase to a full tax valuation allowance for Australia.

The Company [Abstract]
Basis of Presentation	Basis of Presentation We are considered a domestic company in Australia and, as such, are required to report in Australia under International Financial Reporting Standards (“IFRS”). Additionally, as we are not considered a “foreign private issuer” in the United States (“U.S.”), 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. We publish our consolidated financial statements, in both U.S. GAAP and IFRS, in U.S. dollars. Exxaro has a 26% ownership interest in each of our Tronox KZN Sands (Pty) Ltd. and Tronox Mineral Sands (Pty) Ltd. subsidiaries in order to comply with the ownership requirements of the Black Economic Empowerment (“BEE”) legislation in South Africa. We account for such ownership interest as “Noncontrolling interest” in our consolidated financial statements. See Note 21. 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. For the year ended December 31, 2013, we decreased cash flows from investing activities by $7 million with a corresponding decrease in cash flows from operating activities to adjust for accrued capital expenditures. During the year ended December 31, 2014, we recorded out-of-period adjustments that should have been recorded during 2012 that decreased cost of goods sold by $6 million, decreased loss before income taxes by $6 million, decreased net loss by $5 million and decreased loss per share by $0.03. Also during the year ended December 31, 2014, we recorded out-of-period adjustments that should have been recorded during 2013 that increased cost of goods sold by $6 million, increased selling, general and administrative expenses by $1 million, increased loss before income taxes by $7 million, increased net loss by $5 million and increased loss per share by $0.04. After evaluating the quantitative and qualitative aspects of the adjustments, we concluded the effect of these adjustments, individually and in the aggregate, was not material to our previously issued consolidated financial statements or to our 2014 consolidated financial statements. During the year ended December 31, 2015, we recorded out-of-period adjustments that should have been recorded in 2012 through 2014 that decreased cost of goods sold by $5 million, decreased loss before income taxes by $5 million, decreased net loss by $3 million, and decreased loss per share by $0.02. After evaluating the quantitative and qualitative aspects of the adjustments, we concluded the effect of these adjustments, individually and in the aggregate, was not material to our previously issued consolidated financial statements and is not material to our 2015 consolidated financial statements.
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.

Significant Accounting Polici37

Significant Accounting Policies (Policies)	12 Months Ended

Significant Accounting Policies [Abstract]
Foreign Currency	Foreign Currency The U.S. dollar is the functional currency for our operations, except for our South African operations, whose functional currency is the Rand, and our European operations, whose functional currency is the Euro. 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 the 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. Gains and losses on intercompany foreign currency transactions that are not expected to be settled in the foreseeable future are reported in the same manner as translation adjustments.
Revenue Recognition	Revenue Recognition Revenue is recognized when risk of loss and title to the product is transferred to the customer, pricing is fixed or determinable, and collection is reasonably assured. All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as net sales. 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.
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 Operation comprising of salaries, building costs, utilities, administrative expenses, and allocations of corporate costs, were $13 million, $11 million, and $10 million during 2015, 2014, and 2013, 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, 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 weighted 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 for 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 7.
Earnings Per Share	Earnings per Share Basic and diluted earnings per share are calculated using the two-class method. Under the two-class method, earnings used to determine basic earnings per share are reduced by an amount allocated to participating securities. Participating securities include restricted shares issued under the Tronox Management Equity Incentive Plan (see Note 22) and the T-Bucks Employee Participation Plan (see Note 22), both of which contain non-forfeitable dividend rights. Our unexercised options, unexercised Series A and Series B Warrants (see Note 20), and unvested restricted share units do not contain non-forfeitable rights to dividends and, as such, are not considered in the calculation of basic earnings per share. Our unvested restricted shares do not have a contractual obligation to share in losses; therefore, when we record a net loss, none of the loss is allocated to participating securities. Consequently, in periods of net loss, the two class method does not have an effect on basic loss per share. Diluted earnings per share is calculated by dividing net earnings allocable to ordinary shares by the weighted-average number of ordinary shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating restricted share units, options, and Series A and Series B Warrants. The options and Series A and Series B Warrants are included in the calculation of diluted earnings per ordinary share utilizing the treasury stock method. See Note 8.
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 9.
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. At December 31, 2015 and 2014, we had restricted cash in Australia related to outstanding performance bonds of $5 million and $3 million, respectively.
Accounts Receivable, net of allowance for doubtful accounts	Accounts Receivable, net of allowance for doubtful accounts 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 parental guarantees or guarantee payments. We maintain allowances for potential credit losses based on specific customer review and current financial conditions. See Note 10.
Inventories, net	Inventories, net Pigment and Alkali inventories are stated at the lower of actual cost or market (“LOCM”), net of allowances for obsolete and slow-moving inventory. The cost of inventories is determined using the first-in, first-out method (“FIFO”). 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. Mineral Sands 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, annually and at the end of each quarter, the cost of our inventory in comparison to its net realizable value. We also periodically review our inventory for obsolescence (inventory that is no longer marketable for its intended use). 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 11.
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 12. We capitalize interest costs on major projects that require an extended period of time to complete. See Note16. 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 13. Intangible assets are stated at cost less accumulated amortization, and are amortized on a straight-line basis over their estimated useful lives, which range from 3 to 20 years. See Note 14. We evaluate the recoverability of the carrying value of long-lived assets 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. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined.
Business Acquisitions	Business Acquisitions Business acquisitions are accounted for using the acquisition method under Accounting Standards Codification (“ASC”) 805, Business Combinations
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 are recorded in “Other long-term assets” in the Consolidated Balance Sheets, 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 16.
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 Note17.
Derivative Instruments	Derivative Instruments Derivative instruments are recorded in the Consolidated Balance Sheets at their fair values. Changes in the fair value of derivative instruments not designated for hedge accounting treatment are recorded in “Other income (expense), net” in the Consolidated Statements of Operations. See Note 18.
Environmental Remediation and Other Contingencies	Environmental Remediation and Other Contingencies We recognize a loss and record an undiscounted liability when litigation has commenced or a claim or assessment has been asserted, or, based on available information, commencement of litigation or assertion of a claim or assessment is probable, and the associated costs can be reasonably estimated. See Note 19.
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.

(2) The fair value of mineral rights was determined using the Discounted Cash Flow (“DCF” ) method, which was based upon the present value of the estimated future cash flows for the expected life of the asset taking into account the relative risk of achieving those cash flows and the time value of money. A discount rate of 10.4% was used taking into account the risks associated with such assets.

Loss Per Share [Abstract]
Computation of Basic and Diluted Loss Per Share	The computation of basic and diluted loss per share for the periods indicated is as follows: Year Ended December 31, 2015 2014 2013 Numerator – Basic and Diluted: Net loss $ (307 ) $ (417 ) $ (90 ) Less: Net income attributable to noncontrolling interest 11 10 36 Undistributed net loss (318 ) (427 ) (126 ) Percentage allocated to ordinary shares (1) 100 % 100 % 100 % Net loss available to ordinary shares $ (318 ) $ (427 ) $ (126 ) Denominator – Basic and Diluted: Weighted-average ordinary shares (in thousands) 115,566 114,281 113,416 Net loss per Ordinary Share (2) Basic and diluted net loss per ordinary share $ (2.75 ) $ (3.74 ) $ (1.11 ) (1) Our participating securities do not have a contractual obligation to share in losses; therefore, when we have a net loss, none of the loss is allocated to participating securities. Consequently, for 2015, 2014, and 2013, the two-class method did not have an effect on our net loss per ordinary share calculation, and as such, dividends paid during the year did not impact this calculation. (2) Net loss per ordinary share amounts were calculated from exact, not rounded net loss and share information.
Computation of Anti-Dilutive Shares	In computing diluted net loss per share under the two-class method, we considered potentially dilutive shares. Anti-dilutive shares not recognized in the diluted net loss per share calculation were as follows: December 31, 2015 December 31, 2014 December 31, 2013 Shares Average Exercise Price Shares Average Exercise Price Shares Average Exercise Price Options 2,189,967 $ 21.15 2,560,875 $ 21.14 2,094,771 $ 20.63 Series A Warrants (1) 1,354,529 $ 9.63 1,273,917 $ 11.04 1,850,814 $ 11.52 Series B Warrants (1) 1,833,834 $ 10.63 1,715,986 $ 12.19 2,409,404 $ 12.71 Restricted share units 1,494,027 $ 23.04 875,776 $ 22.17 303,324 $ 21.08 (1) Series A Warrants and Series B Warrants were converted into Class A Shares at December 31, 2015, 2014, and 2013 using a rate of 5.66, 5.29, and 5.18, respectively.

[1]	The fair value of property, plant and equipment was determined using the cost approach, which estimates the replacement cost of each asset using current prices and labor costs, less estimates for physical, functional and technological obsolescence, based on the estimated useful life ranging from 5 to 38 years.
[2]	The fair value of mineral rights was determined using the Discounted Cash Flow ("DCF" ) method, which was based upon the present value of the estimated future cash flows for the expected life of the asset taking into account the relative risk of achieving those cash flows and the time value of money. A discount rate of 10.4% was used taking into account the risks associated with such assets.

[1]	Our participating securities do not have a contractual obligation to share in losses; therefore, when we have a net loss, none of the loss is allocated to participating securities. Consequently, for 2015, 2014, and 2013, the two-class method did not have an effect on our net loss per ordinary share calculation, and as such, dividends paid during the year did not impact this calculation.
[2]	Net loss per ordinary share amounts were calculated from exact, not rounded net loss and share information.
