The Company [Abstract]
The Company	1. The Company Tronox Limited and its subsidiaries (collectively referred to as “Tronox Limited,” “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 February 21, 2017, Tronox Limited, The National Titanium Dioxide Company Ltd., a limited company organized under the laws of the Kingdom of Saudi Arabia (“Cristal”), and Cristal Inorganic Chemicals Netherlands Coöperatief W.A., a cooperative organized under the laws of the Netherlands and a wholly owned subsidiary of Cristal (“Seller”), entered into a Transaction Agreement (the “Transaction Agreement”), pursuant to which we agreed to acquire Cristal’s titanium dioxide business for $1.673 billion in cash, subject to a working capital adjustment at closing (the “Cash Consideration”), plus 37,580,000 Class A ordinary shares, par value $0.01 per share, of Tronox Limited (the “Transaction”). Following the closing of the Transaction, the Seller will own approximately 24% of the outstanding ordinary shares (including both Class A and Class B) of Tronox Limited. Concurrently with this announcement, we expressed an intent to begin a process to market our Alkali business. In March 2017, we began to market the Alkali business as well as explore other asset sales and financing options. The Transaction is conditioned on us obtaining financing sufficient to fund the Cash Consideration, and the Transaction Agreement provides that we must pay to Cristal a termination fee of $100 million if all conditions to closing, other than the financing condition, have been satisfied and the Transaction Agreement is terminated because closing of the Transaction has not occurred by May 21, 2018. The Transaction is also conditioned upon the receipt of various regulatory approvals, including antitrust clearance in numerous jurisdictions. On April 13, 2017, the U.S. Federal Trade Commission (“FTC”) issued a second request to us and Cristal in connection with its filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the parties are cooperating to provide the information requested by the FTC as promptly as practicable. The Transaction, which has been unanimously approved by our Board of Directors, is expected to close during the first quarter 2018, subject to regulatory approvals and satisfaction of customary closing conditions, including the favorable vote of a majority of our outstanding shares. 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 19 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 (“U.S.”), 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. Basis of Presentation The accompanying condensed consolidated financial statements are unaudited, and have been prepared pursuant to the rules and regulations of the U. S. Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements, and should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. The Condensed Consolidated Balance Sheet as of December 31, 2016 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, considered necessary for a fair statement. Our unaudited condensed consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements. Revision of Previously Issued Consolidated Financial Statements During the first quarter of 2017, we identified a misstatement in our selling, general, and administrative expense for certain prior periods related to a liability resulting from a non-timely filing with a statutory authority. The aggregate misstatement is $11 million, which impacts our previously issued consolidated statements of operations, comprehensive loss, balance sheets and cash flows as of and for the years ended December 31, 2015 and 2016, and the unaudited condensed consolidated financial statements for the third and fourth quarters of 2015, and each quarter of 2016. In accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements The cumulative amount of the prior period adjustments would have been material to our current statement of operations and comprehensive loss had we made the correction in the current period, and accordingly we will revise our previously issued financial statements to correct this misstatement. Periods not presented herein will be revised, as applicable, in future filings. The effects on our unaudited condensed consolidated financial statements are as follows: Unaudited Condensed Consolidated Statement of Operations Three Months Ended March 31, 2016 As Reported Adjustment Revised Net sales $ 475 $ 1 $ 476 Gross profit 20 1 21 Selling, general and administrative expenses (47 ) (3 ) (50 ) Loss from operations (29 ) (2 ) (31 ) Loss before income taxes (80 ) (2 ) (82 ) Net loss (92 ) (2 ) (94 ) Net loss attributable to Tronox Limited (91 ) (2 ) (93 ) Loss per share, basic and diluted (0.78 ) (0.02 ) (0.80 ) Unaudited Condensed Consolidated Statement of Comprehensive Loss Three Months Ended March 31, 2016 As Reported Adjustment Revised Net loss $ (92 ) $ (2 ) $ (94 ) Total comprehensive loss (38 ) (2 ) (40 ) Comprehensive loss attributable to Tronox Limited (50 ) (2 ) (52 ) Unaudited Condensed Consolidated Balance Sheet December 31, 2016 As Reported Adjustment Revised Accounts receivable, net of allowance for doubtful accounts $ 421 $ 3 $ 424 Total current assets 1,253 3 1,256 Total assets 4,950 3 4,953 Accrued liabilities 174 11 185 Total current liabilities 522 11 533 Total liabilities 3,789 11 3,800 Accumulated deficit (13 ) (6 ) (19 ) Accumulated other comprehensive loss (495 ) (2 ) (497 ) Total Tronox Limited shareholders’ equity 1,017 (8 ) 1,009 Total equity 1,161 (8 ) 1,153 Total liabilities and equity 4,950 3 4,953 Unaudited Condensed Consolidated Statement of Cash Flows The corresponding amounts have been revised within the statement of cash flows for the three months ended March 31, 2016 with no net impact to operating cash flows.

Restructuring Expense [Abstract]
Restructuring Expense	2. Restructuring Expense In March 2017, our Alkali business announced a cost improvement initiative which focused on process improvements at our Wyoming facility (the “Wyoming Restructure”). During the three months ended March 31, 2017, we recorded $1 million of restructuring costs related to the Wyoming Restructure, which was recorded in “Restructuring expense” in the unaudited Condensed Consolidated Statements of Operations. During the three months ended March 31, 2017, we recorded a reversal of restructuring expense of $1 million pursuant to the settlement of claims previously filed relating to a prior restructure. During 2015, we commenced a global restructuring of our TiO 2 This action resulted in a charge, consisting of employee severance and associated costs, of $14 million, which was recorded in “Restructuring expense” in the Consolidated Statements of Operations for the year ended December 31, 2015 of which $2 million was paid during 2015. During the three months ended March 31, 2016, we recorded an additional charge related to our Global TiO 2 Restructure consisting of employee severance cost of $2 million which was recorded in “Restructuring expense” in the unaudited Condensed Consolidated Statements of Operations and made cash payments of $11 million. We paid the remaining $3 million during the second and third quarters of 2016. As part of our cost improvement initiative, in November 2015 we ceased production at our sodium chlorate plant in Hamilton, Mississippi, the “Sodium Chlorate Plant Restructure” which was completed in 2016. This action resulted in a charge, consisting primarily of employee severance costs, of $4 million, which was recorded in “Restructuring expense” in the unaudited Condensed Consolidated Statements of Operations for the year ended December 31, 2015 of which $1 million was paid during 2015. During the three months ended March 31, 2016, we made cash payments of $2 million. The remaining $1 million liability was paid in 2016. The cumulative amount incurred to date relating to the Global TiO2 Restructure, the Sodium Chlorate Plant Restructure and the Wyoming Restructure is $16 million, $4 million and $1 million, respectively. A summary in the changes in the liability established for restructuring, which is included in “Accrued liabilities” in the unaudited Condensed Consolidated Balance Sheets, is as follows: 2017 2016 Balance, January 1, $ — $ 15 Restructuring expense — 2 Cash (payments) receipts 1 (13 ) Balance, March 31, $ 1 $ 4 Restructuring expense by segment for the three months ended March 31, 2017 and 2016 was as follows: Three Months Ended March 31, 2017 Three Months Ended March 31, 2016 TiO 2 $ — $ 1 Alkali 1 — Corporate (1 ) 1 Total $ — $ 2

Income Taxes

Income Taxes [Abstract]
Income Taxes	3. Income Taxes Our operations are conducted through our 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. Three Months Ended March 31, 2017 2016 Income tax provision $ (2 ) $ (12 ) Loss before income taxes $ (36 ) $ (82 ) Effective tax rate (6 )% (15 )% During the fourth quarter of 2016, we implemented various steps of an internal corporate restructuring plan to simplify our corporate, finance and legal structure and thereby improve operational, administrative, and commercial synergies within each of our operating segments (the “Corporate Reorganization”). As a result of this Corporate Reorganization, we reduced our cross jurisdictional financing arrangements during 2016; therefore, the period ended March 31,2017 is not impacted by withholding tax accruals on interest income. In connection with the Corporate Reorganization during the period ended March 31, 2017, Tronox Limited became managed and controlled in the United Kingdom (“U.K”), with no additional impacts to the consolidated provision for income taxes due to the valuation allowances in various jurisdictions. During the three months ended March 31, 2017, Tronox Limited, the public parent which is registered under the laws of the State of Western Australia, became managed and controlled in the U.K. The statutory tax rate in the U.K. at March 31, 2017 was 20%. During 2016, Tronox Limited was taxable only in Australia with a statutory tax rate of 30%. The effective tax rate for the three months ended March 31, 2017 differs from the U.K. statutory rate of 20% primarily due to valuation allowances and income in foreign jurisdictions taxed at rates lower than 20%. The effective tax rate for the three months ended March 31, 2016 differs from the Australian statutory rate of 30% primarily due to valuation allowances, income in foreign jurisdictions taxed at rates lower than 30%, and withholding tax accruals on interest income The statutory tax rates in various countries where subsidiaries of Tronox Limited have operations are different than both the U.K. and the Australian tax rates. Tax rates in the U.S. (35% for corporations), South Africa (28% for limited liability companies), the Netherlands (25% for corporations), Switzerland (8.5% for corporations) and Jersey, U.K. (0% for corporations) all impact our effective tax rate. We continue to maintain full valuation allowances related to the total net deferred tax assets in Australia, the Netherlands, and the U.S., 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, and we have now established a valuation allowance against an immaterial deferred tax asset from a tax loss in the . which we do not expect to utilize. These conclusions were reached by the application of ASC 740, Income Taxes 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 years. 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 March 31, 2017, approximately $2.8 billion of the trust expenditures expected from the litigation proceeds have been incurred.

Loss Per Share [Abstract]
Loss Per Share	4. Loss Per Share The computation of basic and diluted loss per share for the periods indicated is as follows: Three Months Ended March 31, 2017 2016 Numerator – Basic and Diluted: Net loss $ (38 ) $ (94 ) Less: Net income (loss) attributable to noncontrolling interest 3 (1 ) Undistributed net loss (41 ) (93 ) Percentage allocated to ordinary shares (1) 100 % 100 % Net loss available to ordinary shares $ (41 ) $ (93 ) Denominator – Basic and Diluted: Weighted-average ordinary shares (in thousands) 116,815 115,920 Net loss per Ordinary Share (2 ) : Basic and diluted net loss per ordinary share $ (0.35 ) $ (0.80 ) (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 the three months ended March 31, 2017 and 2016, 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: March 31, 2017 March 31, 2016 Shares Average Exercise Price Shares Average Exercise Price Options 1,936,618 21.17 2,078,556 $ 21.16 Series A Warrants 1,432,622 8.51 1,438,289 $ 8.55 Series B Warrants 1,942,323 9.37 1,947,234 $ 9.43 Restricted share units 6,965,668 10.69 5,700,695 $ 7.28

Debt [Abstract]
Debt	11. Debt Our short-term debt consisted of a UBS Revolver, defined below, and was $150 million at both March 31, 2017 and December 31, 2016. The average effective interest rates of our UBS Revolver were 4.6% and 3.9% during the three months ended March 31, 2017 and 2016, respectively. UBS Revolver On June 18, 2012, we entered into 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. 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 years after the closing date and the date which is three months prior to the maturity of the Term Loan, defined below. 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 both March 31, 2017 and December 31, 2016. During each of the three months ended March 31, 2017 and 2016 we had no drawdowns or repayments on the UBS Revolver. At March 31, 2017 and December 31, 2016, our amount available to borrow was $198 million and $190 million, respectively. ABSA Revolving Credit Facility We have a R1.3 billion (approximately $97 million at March 31, 2017) revolving credit facility with ABSA Bank Limited (“ABSA Revolver”) acting through its ABSA Capital Division with a maturity date of June 14, 2017 (the “ABSA”). The ABSA Revolver bears interest at (i) the base rate (defined as one month Johannesburg Interbank Agreed Rate, 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 each of the three months ended March 31, 2017 and 2016, we had no drawdowns or repayments on the ABSA Revolver. At both March 31, 2017 and December 31, 2016, there were no outstanding borrowings on the ABSA Revolver. Long-term debt, net of an unamortized discount and debt issuance costs, consisted of the following: Original Principal Annual Interest Rate Maturity Date March 31, 2017 December 31, 2016 Term Loan, net of unamortized discount (1) $ 1,500 Variable 3/19/2020 $ 1,437 $ 1,441 Senior Notes due 2020 $ 900 6.375 % 8/15/2020 896 896 Senior Notes due 2022 $ 600 7.50 % 3/15/2022 584 584 Lease financing 19 19 Total borrowings under long-term debt 2,936 2,940 Less: Long-term debt due within one year (16 ) (16 ) Debt issuance costs (33 ) (36 ) Long-term debt $ 2,887 $ 2,888 (1) Average effective interest rate of 5.0% and 4.9% during the three months ended March 31, 2017 and 2016, respectively. At March 31, 2017, the scheduled maturities of total borrowings under our long-term debt were as follows: Total Borrowings 2017 $ 12 2018 16 2019 16 2020 2,298 2021 1 Thereafter 597 Total 2,940 Remaining accretion associated with the Term Loan (4 ) Total borrowings under long-term debt $ 2,936 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 March 31, 2017 and December 31, 2016, the unamortized discount was $4 million and $5 million, respectively. We made principal repayments during the three months ended March 31, 2017 and 2016 of $4 million and $3 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. Debt issuance cost related to the Term Loan of $15 million was recorded as a direct reduction to the carrying value of the long-term debt as described below. 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. Debt issuance costs related to the Senior Notes Due 2020 of $9 million were recorded as a direct reduction to the carrying value of the long-term debt as described below. 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. During the three months ended March 31, 2016, we repurchased $4 million of face value of notes at a price of 77% of par, resulting in a net gain of approximately $1 million which was included in “Gain on extinguishment of debt” in the unaudited Condensed Consolidated Statements of Operations. 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 U.S. absent registration or an applicable exemption from registration requirements. During the three months ended March 31, 2016, we repurchased $16 million of face value of notes at a price of 76% of par, resulting in a net gain of approximately $3 million which was included in “Gain on extinguishment of debt” in the unaudited Condensed Consolidated Statements of Operations. 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. Debt issuance costs related to the Senior Notes due 2022 of $9 million were recorded as a direct reduction of the carrying value of the long-term debt as described below. Liquidity and Capital Resources As of March 31, 2017, we had $198 million available under the $500 million UBS Revolver, $97 million available under the ABSA Revolver and $265 million in cash and cash equivalents. Lease Financing We have capital lease obligations in South Africa, which are payable through 2031 at a weighted average interest rate of approximately 14%. Fair Value Our debt is recorded at historical amounts. At both March 31, 2017 and December 31, 2016, the fair value of the Term Loan was $1.5 billion. At March 31, 2017 and December 31, 2016, the fair value of the Senior Notes due 2020 was $903 million and $841 million, respectively. At March 31, 2017 and December 31, 2016, the fair value of the Senior Notes due 2022 was $605 million and $544 million, respectively. 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 Covenants At March 31, 2017, 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. Interest and Debt Expense, Net Interest and debt expense, net in the unaudited Condensed Consolidated Statements of Operations consisted of the following: Three Months Ended March 31, 2017 2016 Interest on debt $ 43 $ 44 Amortization of deferred debt issuance costs and discounts on debt 3 3 Capitalized interest (1 ) (1 ) Other 1 — Total interest and debt expense, net $ 46 $ 46 In connection with obtaining debt, we incurred debt issuance costs, which are being amortized through the respective maturity dates using the effective interest method.

Derivative Instruments

Derivative Instruments	3 Months Ended

Derivative Instruments [Abstract]
Derivative Instruments	13. 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. Our businesses rely on natural gas as one of the main fuel sources in our production process. Natural gas prices have historically been volatile. Natural gas prices could increase as a result of reduced domestic drilling and production activity. Drilling and production operations are subject to extensive federal, state, local and foreign laws and government regulations, which could directly curtail such activity or increase the cost of drilling, resulting in reduced levels of drilling activity and therefore increased natural gas prices. This exposes us to commodity price risk. We mitigate our exposures to currency risks and commodity price risks, through a controlled program of risk management that includes the use of derivative financial instruments. We enter into foreign exchange forward contracts to reduce the effects of fluctuating foreign currency exchange rates. We also use commodity price swap contracts and forward purchase contracts to manage forecasted energy exposure. We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking our hedge transactions. This process includes relating derivatives that are designated as cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also formally assess, both at the inception of the hedge and throughout its term, whether each derivative is highly effective in offsetting changes in cash flows of the hedged item. If we determine that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting with respect to that derivative prospectively. On the date the derivative instrument is entered into, we assess whether to designate the derivative as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge) or not. We recognize all derivatives in the unaudited Condensed Consolidated Balance Sheets at fair value. We have designated our natural gas commodity price swap contracts, which qualify as cash flow hedges, for hedge accounting treatment under ASC 815. We perform an analysis for effectiveness of the derivatives at the end of each quarter based on the terms of the contract and the underlying item being hedged. The effective portion of the change in the fair value of cash flow hedges is deferred in other comprehensive loss and is subsequently recognized in “Cost of goods sold” in the unaudited Condensed Consolidated Statements of Operations for commodity hedges, when the hedged item impacts earnings. Any portion of the change in fair value of derivatives designated as hedging instruments that is determined to be ineffective is recorded in “Other income (expense), net” in the unaudited Condensed Consolidated Statements of Operations. At March 31, 2017 and December 31, 2016, we recorded the fair value of the natural gas hedge of $1 million and $3 million, respectively in “Prepaid and other assets” in the unaudited Condensed Consolidated Balance Sheets, with the offset of $2 million during the three months ended March 31, 2017 of unrealized gain recognized in accumulated other comprehensive loss, with no tax impact, which is expected to be reclassified as earnings within the next nine months. See Note 3 to the unaudited condensed consolidated financial statements. The current open commodity contract hedges forecasted transactions until December 31, 2017. At March 31, 2017 and December 31, 2016, we had an equivalent of 3.8 MMBTUs (millions of British Thermal Units) and 4.8 MMBTUs, respectively, in aggregate notional volume of outstanding natural gas commodity forward contract to hedge forecasted purchases. The fair value of the natural gas commodity price contract was based on market price quotations and the use of a pricing model. The contract was considered a level 2 input in the fair value hierarchy at March 31, 2017 and December 31, 2016.

The following table presents a summary of activity for the three months ended March 31, 2017: Number of Shares Weighted Average Grant Date Fair Value Outstanding, January 1, 2017 284,400 $ 6.09 Vested (107,928 ) 8.00 Outstanding, March 31, 2017 176,472 $ 4.92 Expected to vest, March 31, 2017 176,472 $ 4.92 At March 31, 2017, 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 1.5 years. Since the restricted shares were granted to certain members of our Board as indicated above, the unrecognized compensation expense was not adjusted for estimated forfeitures. Restricted Share Units (“RSUs”) During the three months ended March 31, 2017, 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. For the time-based awards, 100,160 RSUs vest ratably over a one-year period and 773,774 RSUs vest ratably over a three-year period, and are valued at the weighted average grant date fair value. For the performance-based awards, 773,774 cliff vest at the end of the three years and 883,538 cliff vest at the end of forty months. Included in the performance-based awards are 773,774 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 883,538 RSUs were granted, at a grant date fair value of $19.47, to certain executive officers pursuant to an Integration Incentive Award program (the “Integration Incentive Award”) in connection the Cristal Transaction. If the Cristal Transaction does not close by July 1, 2018, then the Integration Incentive Award granted will be forfeited. The following table presents a summary of activity for the three months ended March 31, 2017: Number of Shares Weighted Average Grant Date Fair Value Outstanding, January 1, 2017 5,587,331 $ 7.19 Granted 2,531,246 17.72 Vested (1,052,205 ) 8.74 Forfeited (100,704 ) 13.54 Outstanding, March 31, 2017 6,965,668 $ 10.69 Expected to vest, March 31, 2017 7,539,300 $ 10.02 At March 31, 2017, there was $49 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 2.3 years. The weighted-average grant-date fair value of RSUs granted during the three months ended March 31, 2017 and 2016 was $17.72 per share and $4.06 per share, respectively. The total fair value of RSUs that vested during the three months ended March 31, 2017 was $9 million. Options The following table presents a summary of activity for the three months ended March 31, 2017: Number of Options Weighted Average Exercise Price Weighted Average Contractual Life (years) Intrinsic Value Outstanding, January 1, 2017 1,970,481 $ 21.19 6.38 $ — Forfeited (2,285 ) 21.98 Expired (31,578 ) 22.44 Outstanding, March 31, 2017 1,936,618 $ 21.17 6.13 $ — Expected to vest, March 31, 2017 2,557 $ 27.26 7.48 $ — Exercisable, March 31, 2017 1,934,029 $ 21.16 6.13 $ — 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 period. The amount will change based on the fair market value of our stock. No options were exercised during the three months ending March 31, 2017 and 2016 and consequently, there was no related intrinsic value Since no stock options were exercised during the three months ended March 31, 2017 and 2016, no cash was received. At March 31, 2017 there was no unrecognized compensation expense related to options, adjusted for estimated forfeitures. We did not issue any options d 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. Dividend yield is determined based on the Company’s expected dividend payouts. 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 March 31, 2017 and December 31, 2016 was 548,234 shares. Long-Term Incentive Plan (“LTIP”) We have a 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 both March 31, 2017 and December 31, 2016, the LTIP plan liability was less than $1 million.

Pension and Other Postretirement Healthcare Benefits	18. Pension and Other Postretirement Healthcare Benefits We sponsor two noncontributory defined benefit retirement plans in the United States, the qualified retirement plan and Alkali qualified retirement plan (the “U.S. Defined Benefit Plans”). We also have a collective defined contribution plan (a multiemployer plan) in the Netherlands, and a postretirement healthcare plan in South Africa. We had a defined benefit retirement plan in the Netherlands which was settled in the fourth quarter of 2016. The components of net periodic cost associated with our U.S. Defined Benefit Plans and the Netherlands defined benefit plan recognized in the unaudited Condensed Consolidated Statements of Operations were as follows: Three Months Ended March 31, 2017 2016 Net periodic cost: Service cost $ 1 $ 1 Interest cost 4 5 Expected return on plan assets (4 ) (5 ) Net amortization of actuarial losses 1 1 Total net periodic cost $ 2 $ 2 The components of net periodic cost associated with the postretirement healthcare plan for each of the three months ended March 31, 2017 and 2016 were less than $1 million. For each of the three months ended March 31, 2017 and 2016, we contributed $1 million to the Netherlands multiemployer plan, which was recognized in “Selling general and administrative expense” in the unaudited Condensed Consolidated Statement of Operations.

Acquisition of Alkali Chemicals Group [Abstract]
Acquisition of Alkali Chemicals Group	19. 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 3 for a discussion of the tax impact of the Alkali Transaction. We accounted for the Alkali Transaction using the acquisition method under ASC 805, Business Combinations We funded the Alkali Transaction through existing cash and new debt. See Note 11 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 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 were 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.

Guarantor Condensed Consolidating Financial Statements [Abstract]
Guarantor Condensed Consolidating Financial Statements	22. 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 indenture governing the Senior Notes due 2020 provides 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. At December 31, 2016, certain entities which were created as part of the Corporate Reorganization were designated as non-guarantor entities. As of and during the three months ended March 31, 2017, pursuant to the Seventh Supplemental Indenture, dated as of February 14, 2017, to the Indenture, dated August 20, 2012 among Tronox Finance LLC, as Issuer, Tronox Limited as Parent, the guarantors named therein and Wilmington Trust, National Association, as trustee, these entities have been designated as guarantor entities. Consequently, the unaudited guarantor condensed consolidating financial information for these entities has been revised, retrospectively, to reflect the change in structure.

The Company [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements are unaudited, and have been prepared pursuant to the rules and regulations of the U. S. Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements, and should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. The Condensed Consolidated Balance Sheet as of December 31, 2016 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, considered necessary for a fair statement. Our unaudited condensed consolidated financial statements include the accounts of all majority-owned subsidiary companies. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements.
Revision of Previously Issued Consolidated Financial Statements	Revision of Previously Issued Consolidated Financial Statements During the first quarter of 2017, we identified a misstatement in our selling, general, and administrative expense for certain prior periods related to a liability resulting from a non-timely filing with a statutory authority. The aggregate misstatement is $11 million, which impacts our previously issued consolidated statements of operations, comprehensive loss, balance sheets and cash flows as of and for the years ended December 31, 2015 and 2016, and the unaudited condensed consolidated financial statements for the third and fourth quarters of 2015, and each quarter of 2016. In accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements The cumulative amount of the prior period adjustments would have been material to our current statement of operations and comprehensive loss had we made the correction in the current period, and accordingly we will revise our previously issued financial statements to correct this misstatement. Periods not presented herein will be revised, as applicable, in future filings. The effects on our unaudited condensed consolidated financial statements are as follows: Unaudited Condensed Consolidated Statement of Operations Three Months Ended March 31, 2016 As Reported Adjustment Revised Net sales $ 475 $ 1 $ 476 Gross profit 20 1 21 Selling, general and administrative expenses (47 ) (3 ) (50 ) Loss from operations (29 ) (2 ) (31 ) Loss before income taxes (80 ) (2 ) (82 ) Net loss (92 ) (2 ) (94 ) Net loss attributable to Tronox Limited (91 ) (2 ) (93 ) Loss per share, basic and diluted (0.78 ) (0.02 ) (0.80 ) Unaudited Condensed Consolidated Statement of Comprehensive Loss Three Months Ended March 31, 2016 As Reported Adjustment Revised Net loss $ (92 ) $ (2 ) $ (94 ) Total comprehensive loss (38 ) (2 ) (40 ) Comprehensive loss attributable to Tronox Limited (50 ) (2 ) (52 ) Unaudited Condensed Consolidated Balance Sheet December 31, 2016 As Reported Adjustment Revised Accounts receivable, net of allowance for doubtful accounts $ 421 $ 3 $ 424 Total current assets 1,253 3 1,256 Total assets 4,950 3 4,953 Accrued liabilities 174 11 185 Total current liabilities 522 11 533 Total liabilities 3,789 11 3,800 Accumulated deficit (13 ) (6 ) (19 ) Accumulated other comprehensive loss (495 ) (2 ) (497 ) Total Tronox Limited shareholders’ equity 1,017 (8 ) 1,009 Total equity 1,161 (8 ) 1,153 Total liabilities and equity 4,950 3 4,953 Unaudited Condensed Consolidated Statement of Cash Flows The corresponding amounts have been revised within the statement of cash flows for the three months ended March 31, 2016 with no net impact to operating cash flows.

Consequently, for the three months ended March 31, 2017 and 2016, 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.

[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 the three months ended March 31, 2017 and 2016, 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.

[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 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.
