1. The Company

Tronox Limited, a public limited company registered under the laws of the State of Western Australia, Australia, and its subsidiaries (collectively referred to as “Tronox” or “the Company”) is a global leader in the production and marketing of titanium bearing mineral sands and titanium dioxide pigment (“TiO₂”). The Company’s world-class, high performance TiO₂ products are critical components of everyday applications such as paint and other coatings, plastics, paper and other applications. The Company’s mineral sands business consists primarily of two product streams—titanium feedstock and zircon. Titanium feedstock is primarily used to manufacture TiO_2. Zircon, a hard, glossy mineral, is used for the manufacture of ceramics, refractories, TV screen glass and a range of other industrial and chemical products. Tronox has global operations in North America, Europe, South Africa and Australia. The Company operates three TiO₂ facilities at the following locations: Hamilton, Mississippi, Botlek, the Netherlands, and Kwinana, Western Australia, representing approximately 465,000 tonnes of annual TiO₂ production capacity. Additionally, Tronox operates three separate mining operations: KwaZulu-Natal (“KZN”) Sands located in South Africa, Namakwa Sands located in South Africa and Cooljarloo located in Western Australia, which have a combined annual production capacity of approximately 753,000 tonnes of titanium feedstock and approximately 265,000 tonnes of zircon.

Tronox Limited was formed on September 21, 2011 for the purpose of the Transaction (defined below). Prior to the completion of the Transaction, Tronox Limited was wholly-owned by Tronox Incorporated, and had no operating assets or operations. On September 25, 2011, Tronox Incorporated, a Delaware corporation formed on May 17, 2005 (“Tronox Incorporated”), in preparation for the contribution and transfer by Kerr-McGee Corporation of certain entities, including those comprising substantially all its chemical business, entered into a definitive agreement (as amended, the “Transaction Agreement”) with Exxaro Resources Limited (“Exxaro”) and certain of its affiliated companies, to acquire 74% of its South African mineral sands operations, including its Namakwa and KZN Sands mines, separation facilities and slag furnaces, along with its 50% share of the Tiwest Joint Venture (together the “mineral sands business”) (the “Transaction”). On June 15, 2012, the date of the Transaction (the “Transaction Date”), 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 in a tax inversion transaction.

On May 4, 2012, Tronox Limited registered Class A ordinary shares (“Class A Shares”) to be issued to shareholders of Tronox Incorporated in connection with the completion of the Transaction. On the Transaction Date, Tronox Limited issued 9,950,856 Class B ordinary shares (“Class B Shares”) to Exxaro and one of its subsidiaries in consideration for the mineral sands business. Under the terms of the Transaction Agreement, Exxaro agreed that for a three-year period after the completion of the Transaction, it would not engage in any transaction or other action, that would result in its beneficial ownership of the voting shares of Tronox Limited to exceed 45% of the total issued shares of Tronox Limited. At March 31, 2013, Exxaro held approximately 44.4% of the voting securities of Tronox Limited.

2. Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited, and have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The December 31, 2012 balance sheet was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP for complete financial statements.

The unaudited condensed consolidated balance sheets as of March 31, 2013 and December 31, 2012 relate to Tronox Limited. The unaudited condensed consolidated statements of operations and cash flows for the three months ended March 31, 2013 reflect the consolidated operating results of Tronox Limited. The unaudited condensed consolidated statements of operations and cash flows for the three months ended March 31, 2012 reflect the consolidated operating results of Tronox Incorporated.

Prior to the Transaction Date, Tronox Incorporated operated the Tiwest Joint Venture with Exxaro Australia Sands Pty Ltd. The Tiwest Joint Venture was a contractual relationship between Tronox Incorporated and Exxaro whereby each party held an undivided interest in each asset of the joint venture, and each party was proportionally liable for each of the joint venture’s liabilities. The Tiwest Joint Venture was not a separate legal entity and did not enter into any transactions. Transactions were entered into by the joint venture partners who had the right to sell their own product, collect their proportional share of the revenues and absorb their share of costs. As such, Tronox Incorporated did not account for the Tiwest Joint Venture under the equity method. Instead, Tronox

TRONOX LIMITED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Millions of U.S. dollars, except share and per share data or unless otherwise noted)

Incorporated accounted for its share of the Tiwest Joint Venture’s assets that were jointly controlled and its share of liabilities for which it was jointly responsible on a proportionate gross basis in its unaudited Condensed Consolidated Balance Sheet. Additionally, Tronox Incorporated accounted for the revenues generated from its share of the products sold and its share of the expenses of the joint venture on a gross basis in its unaudited Condensed Consolidated Statements of Operations. As of the Transaction Date, the Company owns 100% of the Tiwest Joint Venture operations. As such, the unaudited Condensed Consolidated Balance Sheets at March 31, 2013 and December 31, 2012 includes 100% of the Tiwest operations assets and liabilities. The unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2013 reflect 100% of the revenue and expenses of the Tiwest operations, while the unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2012 reflects Tronox Incorporated’s revenues generated from its share of the products sold and its share of the expenses of the joint venture on a gross basis.

In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation. 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 within one year of the date of the financial statements due to one or more future confirming events could have a material effect on the financial statements. The consolidated results of operations for interim periods are not necessarily indicative of results for the entire year.

Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period. Such reclassifications did not have an impact on the Company’s net income or consolidated results of operations.

3. Recent Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (the “FASB”) issued accounting standards update (“ASU”) 2013-5, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-5”), which addresses the treatment of the cumulative translation adjustment into net income when a parent either sells its investment in a foreign entity or no longer holds controlling financial interest in a subsidiary or group of assets within a foreign entity. ASU 2013-5 is effective prospectively for periods beginning after December 15, 2013; however early adoption is permitted. The Company has not yet determined the impact, if any, that ASU 2013-5 will have on the consolidated financial statements.

During 2013, the Company adopted ASU 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires the presentation of the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, if the item is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The adoption of this guidance did not have a significant impact on the consolidated financial statements.

4. Acquisition of the Mineral Sands Business

On September 25, 2011, Tronox Incorporated entered into the Transaction Agreement with Exxaro to acquire the mineral sands business. The Company accounted for the Transaction under Accounting Standards Codification (“ASC”) 805, Business Combinations, (“ASC 805”). The excess of the fair value of the net assets acquired over the value of consideration was recorded as an initial bargain purchase gain. Subsequent to the Transaction, the Company made adjustments to its initial valuation. Further adjustments may result before the end of the measurement period, which ends in June 2013. The bargain purchase gain was not taxable for income tax purposes.

UBS Revolver

On June 18, 2012, in connection with the closing of the Transaction, the Company entered into a global senior secured asset-based syndicated revolving credit agreement with UBS AG (the “UBS Revolver”). The UBS Revolver provides the Company with a committed source of capital with a principal borrowing amount of up to $300 million, subject to a borrowing base. In connection with its entry into the Amended and Restated Credit Agreement on March 19, 2013, the Company amended the UBS Revolver to allow for the increased size of the Term Loan over the Term Facility (see “Term Loan” below). At March 31, 2013, the Company’s available borrowing base was $275 million.

In connection with obtaining the UBS Revolver, the Company incurred debt issuance costs of approximately $7 million. During the three months ended March 31, 2013, amortization expense amounted to less than $1 million.

ABSA Revolving Credit Facility

In connection with the Transaction, the Company entered into a R900 million (approximately $98 million as of March 31, 2013) revolving credit facility with ABSA Bank Limited acting through its ABSA Capital Division (the “ABSA Revolver”). During the three months ended March 31, 2013, the Company had repayments of R250 million (approximately $29 million). At March 31, 2013, the Company had no amounts drawn on the ABSA Revolver.

In connection with obtaining the ABSA Revolver, the Company incurred debt issuance costs of $1 million. During the three months ended March 31, 2013, amortization expense amounted to less than $1 million.

Wells Revolver

On February 14, 2011, Tronox Incorporated entered into a $125 million senior secured asset-based revolving credit agreement with Wells Fargo Capital Finance, LLC (the “Wells Revolver”). The Wells Revolver provided the Company with a committed source of capital with a principal borrowing amount of up to $125 million subject to a borrowing base. On February 8, 2012, the Company amended the Wells Revolver to facilitate the Transaction while keeping the revolver in force. During 2012, the Company borrowed $30 million against the Wells Revolver, which was repaid with borrowings under the UBS Revolver. On June 18, 2012, the Company refinanced the Wells Revolver with the UBS Revolver.

Term Facility

On February 8, 2012, Tronox Incorporated’s wholly-owned subsidiary, Tronox Pigments (Netherlands) B.V., entered into a term loan facility with Goldman Sachs Bank USA comprised of a $550 million Senior Secured Term Loan (the “Senior Secured Term Loan”) and a $150 million Senior Secured Delayed Draw Term Loan (the “Senior Secured Delayed Draw” together, the “Term Facility”). The Term Facility was issued net of an original issue discount of $7 million, or 1% of the initial principal amount, which is being amortized over the life of the Term Facility. On June 14, 2012, in connection with the closing of the Transaction, Tronox Pigments (Netherlands) B.V. drew down the $150 million Senior Secured Delayed Draw. In connection with obtaining the Term Facility, Tronox Incorporated incurred debt issuance costs of $17 million, which are recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets, and are being amortized through the maturity date.

On February 28, 2013, Tronox Pigments (Netherlands) B.V. repaid the outstanding principal balance of $149 million, plus interest, related to the $150 million Senior Secured Delayed Draw. In accordance with ASC 470, Debt, (“ASC 470”), the Company accounted for such repayment as an extinguishment of debt. As such, the Company recognized a loss on the early extinguishment of debt of $4 million related to the allocated portion of the unamortized original issue discount and debt issuance costs.

Term Loan

On March 19, 2013, Tronox Pigments (Netherlands) B.V., Tronox Limited, and certain subsidiaries of Tronox Limited named as guarantors, entered into an Amended and Restated Credit and Guaranty 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 Amended and Restated Credit Agreement, the Company obtained a $1.5 billion senior secured term loan (the “Term Loan”), which matures in March 2020. The terms of the Amended and Restated Credit Agreement are substantially similar to the Company’s prior Term Facility. The Term Loan was issued net of an original issue discount of $7 million, or 0.5% of the principal balance.

In accordance with ASC 470, the outstanding principal balance of the Senior Secured Term Loan of $547 million, which became part of the Term Loan, was accounted for as a debt modification. As such, the unamortized original issue discount of $5 million and debt issuance costs of $11 million related to the Term Facility will continue to be amortized over the life of the Term Loan.

The Term Loan bears interest at a base rate plus the applicable margin of 2.5% per annum, or adjusted Eurodollar rate plus the applicable margin of 3.5% per annum. The base rate is defined as the greater of (i) the prime lending rate as quoted in the print edition of The Wall Street Journal or (ii) the Federal Funds Effective rate in effect on such day plusone half of 1%; provided, however, that the Base Rate is not less than 2% per annum.

Additionally, in connection with obtaining the Term Loan, the Company incurred debt issuance costs of $28 million, which are recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets, and are being amortized through the maturity date. For the three month ended March 31, 2013, amortization expense amounted to less than $1 million.

Senior Notes

On August 20, 2012, Tronox Limited’s wholly-owned subsidiary, Tronox Finance LLC, issued $900 million aggregate principal amount of 6.375% senior notes due 2020 (the “Senior Notes”). The Senior Notes were 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. The Senior Notes bear interest semiannually at a rate equal to 6.375% and were sold at par value. The Senior Notes are fully and unconditionally guaranteed on a senior, unsecured basis by Tronox Limited and certain of its subsidiaries. The Senior Notes are redeemable at any time at the Company’s discretion. The Senior Notes and related guarantees have not been registered under the Securities Act, or any state securities laws, and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws.

The Company recorded debt issuance fees of $18 million, which are being amortized over the life of the debt, and are included in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets. During the three months ended March 31, 2013, amortization expense amounted to $1 million.

Exit Financing Facility

On February 14, 2011, Tronox Incorporated’s senior secured super-priority DIP and Exit Credit Agreement with Goldman Sachs Lending Partners, in accordance with its terms, converted into a $425 million exit facility with a maturity date of October 21, 2015 (the “Exit Financing Facility”). On February 8, 2012, Tronox Incorporated refinanced the Exit Facility with the Term Facility, as discussed above. In connection with the refinancing, the Company repaid $421 million.

Co-generation Unit Financing Arrangement

In March 2011, in order to finance its share of the asset purchase for the Tiwest Joint Venture, Tronox Incorporated incurred debt totaling $8 million. In connection with the Transaction, the Company acquired the remaining 50% undivided interest in the co-generation plant from Exxaro, along with its debt of $6 million. Under the financing arrangement, monthly payments are required, and interest accrues on the outstanding balance at the rate of 6.5% per annum. During the three months ended March 31, 2013, the Company made principal repayments of approximately $1 million.

Lease Financing

In connection with the Transaction, the Company acquired capital lease obligations in South Africa, which are payable through 2032 at a weighted average interest rate of approximately 17%. At March 31, 2013, such obligations had a net book value of assets recorded under capital leases aggregating $8 million. During 2013, the Company made payments of less than $1 million.

Fair Value

The Company’s debt is recorded at historical amounts. At March 31, 2013, the fair value of the Term Loan and Senior Notes was $1,523 million and $882 million, respectively. The Company determined the fair value of both the Senior Notes and the Term Loan using the Bloomberg market price as of March 31, 2013. At December 31, 2012, the fair value of the Senior Notes and the Term Facility was $910 million and $709 million, respectively. The fair value hierarchy for long-term debt is a Level 2 input.

Debt Covenants

At March 31, 2013, the Company had financial covenants in the UBS Revolver, the ABSA Revolver and the Term Loan.

The terms of the Amended and Restated Credit Agreement are substantially similar to the Company’s prior Credit and Guaranty Agreement with Goldman Sachs Bank USA, dated February 8, 2012, except that the Amended and Restated Credit Agreement (i) eliminates financial maintenance covenants (ii) permits, subject to certain conditions, incurrence of additional senior secured debt up to a leverage ratio of 2:1, (iii) increases the Company’s ability to incur debt in connection with permitted acquisitions and its ability to incur unsecured debt, and (iv) allows for the payment of a $0.25 per share dividend each fiscal quarter . Otherwise, the terms of the Amended and Restated Credit Agreement provide for customary representations and warranties, affirmative and negative covenants and events of default. The terms of the covenants, subject to certain exceptions, restrict, among other things: (i) debt incurrence; (ii) lien incurrence; (iii) investments, dividends and distributions; (iv) disposition of assets and subsidiary interests; (v) acquisitions; (vi) sale and leaseback transactions; and (vii) transactions with affiliates and shareholders.

The Term Facility 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. At March 31, 2013, only the ABSA Revolver had a financial maintenance covenant. The Company was in compliance with its financial covenants at March 31, 2013.

The Company has pledged the majority of our U.S. assets and certain assets of its non-U.S. subsidiaries in support of its outstanding debt.

Interest and Debt Expense

Interest and debt expense consisted of the following:

12. Asset Retirement Obligations

To the extent a legal obligation exists, an asset retirement obligation (“ARO”) is recorded at its 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 Tronox’s credit-adjusted risk-free interest rate. The Company classifies accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” on the unaudited Condensed Consolidated Statements of Operations.

Environmental Rehabilitation Trust

The Company has established an environmental rehabilitation trust in respect of the prospecting and mining operations in South Africa in accordance with applicable regulations. The trustees of the fund are appointed by the Company, and consist of sufficiently qualified Tronox Limited employees capable of fulfilling their fiduciary duties. The environmental rehabilitation trust receives, holds, and invests funds for the rehabilitation or management of negative environmental impacts associated with mining and exploration activities. The contributions are aimed at providing sufficient funds at date of estimated closure of mining activities to address the rehabilitation and environmental impacts. Funds accumulated for a specific mine or exploration project can only be utilized for the rehabilitation and environmental impacts of that specific mine or project. Currently, the funds are invested in highly liquid, short-term instruments; however, the investment growth strategy has not been finalized. If a mine or exploration project withdraws from the fund for whatever valid reason, the funds accumulated for such mine or exploration project are transferred to a similar fund approved by management. At March 31, 2013 and December 31, 2012, the environmental rehabilitation trust assets were $19 million and $20 million, respectively, which were recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets.

13. Commitments and Contingencies

Purchase Commitments—At March 31, 2013, purchase commitments were $99 million for the remainder of 2013, $95 million for 2014, $33 million for 2015, $20 million for 2016, $19 million for 2017 and $111 million thereafter.

Letters of Credit—At March 31, 2013, the Company had outstanding letters of credit, bank guarantees and performance bonds of approximately $51 million, of which $25 million in letters of credit were issued under the UBS Revolver and $18 million were bank guarantees issued by ABSA.

Legal—The Western Australia Office of State Revenue (the “OSR”) continues to review their technical position on the imposition of stamp duty on the transfer of Tronox Incorporated’s shares related to Kerr-McGee’s restructuring in 2002 and from the share transfer related to the spinoff of Tronox Incorporated from Kerr-McGee in 2005. On January 17, 2012, the OSR contacted the Company seeking additional information related to the 2005 spinoff. On October 20, 2012, the OSR rendered its assessment of $5 million, comprised of a primary stamp duty liability of $3 million and penalty tax of $2 million. The Company had accrued $3 million at December 31, 2012, which was recorded in “Trade and other payables” in the unaudited Condensed Consolidated Balance Sheets. As required by law, the Company paid the entire amount of the assessment in January 2013; however it has submitted an objection to the penalty, setting out the reasons that the Commissioner of State Revenue has erred in the imposition of the penalty. The decision is expected in respect of this matter in 2013. If the objection is unsuccessful, the Company may appeal to the State Administrative Tribunal for review of the decision. The Company intends to exercise all its legal and administrative options in order to oppose the imposition of the penalty.

Environmental Contingencies—In accordance with ASC 450, Contingencies, the Company recognizes a loss and records an undiscounted liability when litigation has commenced or a claim or an 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 estimated. It is not possible for the Company to reliably estimate the amount and timing of all future expenditures related to environmental matters because, among other reasons, environmental laws and regulations, as well as enforcement policies and clean up levels, are continually changing, and the outcome of court proceedings, alternative dispute resolution proceedings (including mediation) and discussions with regulatory agencies are inherently uncertain.

The Company believes that it has reserved adequately for the probable and reasonably estimable costs of known contingencies. There is no environmental litigation, claim or assessment that has been asserted nor is there any probability of an assessment or a claim for which the Company has not recorded a liability. However, additions to the reserves may be required as additional information is obtained that enables the Company to better estimate its liabilities. The Company cannot reliably estimate the amount of future additions to the reserves at this time. In certain situations, reserves may be probable but not estimable. Additionally, sites may be identified in the future where the Company could have potential liability for environmental related matters. If a site is identified, the Company will evaluate to determine what reserve, if any, should be established.

Other Matters—From time to time, the Company may be party to a number of legal and administrative proceedings involving environmental and/or other matters in various courts or agencies. These proceedings, individually and in the aggregate, may have a material adverse effect on the Company. These proceedings may be associated with facilities currently or previously owned, operated or used by the Company and/or its predecessors, some of which may include claims for personal injuries, property damages, cleanup costs and other environmental matters. Current and former operations of the Company may also involve management of regulated materials, which are subject to various environmental laws and regulations including the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”), the Resource Conservation and Recovery Act (the “RCRA”) or state equivalents. Similar environmental laws and regulations and other requirements exist in foreign countries in which the Company operates.

16. Income Taxes

The Company’s operations are conducted through its various subsidiaries in a number of countries throughout the world. The Company has provided for income taxes based upon the tax laws and rates in the countries in which operations are conducted and income is earned. For the three months ended March 31, 2013, Tronox Limited is the public parent registered under the laws of the State of Western Australia. For the three months ended March 31, 2012, Tronox Incorporated was the public parent, a Delaware corporation, registered in the United States.

The negative effective tax rate for the three months ended March 31, 2013, differs from the Australian statutory rate of 30% primarily due to withholding tax accruals, valuation allowances in the United States, and income in foreign jurisdictions taxed at rates different than 30%. The effective tax rate for the three months ended March 31, 2012, differs from the US statutory rate of 35% primarily due to valuation allowances in the United States and income in foreign jurisdictions taxed at rates different than 35%.

The Company continues to maintain a valuation allowance related to the net deferred tax assets in the United States. Future provisions for income taxes will include no tax benefits with respect to losses incurred and tax expense only to the extent of current alternative minimum tax and state tax payments until the valuation allowance in the United States is eliminated. ASC 740, Income Taxes, requires that all available positive and negative evidence be weighted to determine whether a valuation allowance should be recorded.

17. Earnings (Loss) Per Share

Basic earnings (loss) per share is computed utilizing the two-class method, and is calculated based on weighted-average number of ordinary shares outstanding during the periods presented. Diluted earnings (loss) per share is computed using the weighted-average number of ordinary and ordinary equivalent shares outstanding during the periods utilizing the two-class method for nonvested restricted shares, warrants and options.

Certain unvested awards issued under the Tronox Limited Management Equity Incentive Plan and the T-Bucks Employee Participation Plan contain non-forfeitable rights to dividends declared on Class A Shares. Any unvested shares that participate in dividends are considered participating securities and are included in the Company’s computation of basic and diluted earnings per share using the two-class method, unless the effect of including such shares would be antidilutive. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of ordinary shares and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings.

The following table sets forth the number of shares utilized in the computation of basic and diluted earnings (loss) per share for the periods indicated. The weighted average shares outstanding, potentially dilutive shares, earnings per share and anti-dilutive shares have been restated to affect the 5-for-1 share split.

(1) The basic and diluted earnings (loss) per share amounts were computed from exact, not rounded, income and share information.

In computing diluted earnings (loss) per share under the two-class method, the Company considered potentially dilutive shares. For the three months ended March 31, 2013, 2,027,304 options with an average exercise price of $20.56 were not recognized in the diluted earnings per share calculation as they were antidilutive.

18. Share-based Compensation

Compensation expense related to restricted share awards was $2 million and $6 million for the three months ended March 31, 2013 and 2012, respectively. Compensation expense related to the Company’s nonqualified option awards was $2 million and $1 million for the three months ended March 31, 2013 and 2012, respectively.

At March 31, 2013, unrecognized compensation expense related to the Company’s restricted shares and options, adjusted for estimated forfeitures, was approximately $54 million, with such unrecognized compensation expense expected to be recognized over a weighted-average period of approximately three years. The ultimate amount of such expense is dependent upon the actual number of restricted shares and options that vest. The Company periodically assesses the forfeiture rates used for such estimates. A change in estimated forfeiture rates would cause the aggregate amount of compensation expense recognized in future periods to differ from the estimated unrecognized compensation expense above.

On the Transaction Date, Tronox Limited adopted the Tronox Limited Management Equity Incentive Plan (the “Tronox Limited MEIP”), which permits the grant of awards that constitute incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards and other share-based awards, cash payments and other forms such as the compensation committee of the Board in its discretion deems appropriate, including any combination of the above. 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 the three months ended March 31, 2013, the Company granted 708,908 restricted share awards to employees, which have both time requirements and performance requirements. The time provisions are graded vesting, while the performance provisions are cliff vesting and have a variable payout. During the three months ended March 31, 2013, the Company granted 71,732 restricted share awards with graded vesting to members of the Board. In accordance with ASC 718, Compensation – Share-Based Compensation (“ASC 718”), the restricted share awards issued during the three months ended March 31, 2013 are classified as equity awards and are accounted for using the fair value established at the grant date.

Grants

Valuation and Cost Attribution Methods. Options’ fair value are determined on the date of grant 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 necessary to earn the awards, which is the vesting period. The Company ran the Black-Scholes option-pricing model for the 1,545,662 options granted on February 25, 2013 and the 8,238 options granted on March 11, 2013 using the following assumptions:

	February 25, 2013			March 11, 2013
Risk-free interest rate		1.04	%		1.19	%
Expected dividend yield		5.24	%		4.65	%
Expected volatility		56	%		56	%
Expected term (years)		10			10
Per-unit fair value of options granted	$	6.28		$	7.48

For the February 25, 2013 grant, the Company used the fair market value and exercise price of $19.09, which was the adjusted closing price of Class A Shares, New York Stock Exchange symbol TROX, recorded on February 25, 2013. For the March 11, 2013 grant, the Company used the fair market value and exercise price of $21.49, which was the adjusted closing price of Class A Shares, New York Stock Exchange symbol TROX, recorded on March 11, 2013.

Risk-free interest rate — The Company used a risk-free interest rate of 1.04% and 1.19% for the February 25, 2013 grant and the March 11, 2013 grant, respectively, which was the risk-free interest rate based on U.S. Treasury Strips available with maturity period consistent with expected life assumption.

Expected Volatility — In setting the volatility assumption, the Company considered the most recent reported volatility of each compensation peer company. For the 2013 valuation, the peer company group included the following companies: Albemarle, Cabot Corporation, Celanese Corporation, Chemtura Corporation, Cliffs Natural Resources Inc., Cytec Industries Inc., Dupont, Eastman Chemical Company, Freeport-McMoRan Copper & Gold Inc., Huntsman Corporation, Kronos Worldwide, Inc., Rockwood Holdings, Inc., Southern Copper Corporation, and Teck Resources Limited.

T-Bucks Employee Participation Plan (“T-Bucks EPP”)

At March 31, 2013 and December 31, 2012, there were 548,234 shares in the trust with a fair value of $25.79, which represents the fair value on the date of purchase by the trust. Compensation expense during the three months ended March 31, 2013 was $1 million.

Long-Term Incentive Plan

In connection with the Transaction, the Company assumed 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 remeasured to fair value at each reporting date. At March 31, 2013, the LTlP plan liability was approximately $3 million, which is recorded in “Other long-term liabilities” on the unaudited Condensed Consolidated Balance Sheets. During the three months ended March 31, 2013, compensation expense was less than $1 million.

Tronox Incorporated Management Equity Incentive Plan

In connection with its emergence from bankruptcy, Tronox Incorporated adopted the Tronox Incorporated management equity incentive plan (the “Tronox Incorporated MEIP”), which permitted the grant of awards that constitute incentive options, nonqualified options, share appreciation rights, restricted share, restricted share units, performance awards and other share-based awards, cash payments and other forms such as the compensation committee of the Tronox Incorporated Board of Directors in its discretion deems appropriate, including any combination of the above. The number of shares available for delivery pursuant to the awards granted under the Tronox Incorporated MEIP was 1.2 million shares.

On the Transaction Date, 748,980 restricted shares of Tronox Incorporated vested in connection with the Transaction. The remaining restricted shares of Tronox Incorporated were converted to Tronox Limited restricted shares. Additionally, on the Transaction Date, 517,330 Tronox Incorporated options were converted to Tronox Limited options.

The components of the Company’s net periodic cost for the postretirement healthcare plans for the three months ended March 31, 2013 and 2012 were below $1 million.

20. Related Party Transactions

On September 25, 2011, Tronox Incorporated entered into the Transaction Agreement with Exxaro to acquire the mineral sands business. At March 31, 2013, Exxaro held approximately 44.4% of the voting securities of Tronox Limited. During the three months ended March 31, 2013, the Company purchased transition services from Exxaro, which amounted to $1 million. At March 31, 2013, the Company had a receivable from Exxaro of $1 million related to payments made by Tronox on Exxaro’s behalf.

Prior to the Transaction Date, Tronox Incorporated conducted transactions with Exxaro Australia Sands Pty Ltd, Tronox Incorporated’s 50% partner in the Tiwest Joint Venture. Tronox Incorporated purchased, at open market prices, raw materials used in its production of TiO₂, as well as Exxaro Australia Sands Pty Ltd’s share of TiO₂ produced by the Tiwest Joint Venture. Tronox Incorporated also provided administrative services and product research and development activities, which were reimbursed by Exxaro. For the three months ended March 31, 2012, the Company made payments of $83 million and received payments of $7 million related to these transactions.

21. Segment Information

Prior to the Transaction, Tronox Incorporated had one reportable segment representing its pigment business. The Pigment segment primarily produced and marketed TiO_2, and included heavy minerals production. The heavy minerals production was integrated with its Australian pigment plant, but also had third-party sales of minerals not utilized by its pigment operations. In connection with the Transaction, the Company acquired 74% of Exxaro’s South African mineral sands operations, including its Namakwa and KZN Sands mines, separation facilities and slag furnaces, along with its 50% share of the Tiwest Joint Venture in Western Australia. As such, the Company evaluated its new operations under ASC 280, Segments, and determined that the mineral sands operations qualify as a separate segment.

Subsequent to the Transaction, the Company has two reportable segments, Mineral Sands and Pigment. The Mineral Sands segment includes the exploration, mining and beneficiation of mineral sands deposits, as well as heavy mineral production. These operations produce titanium feedstock, including ilmenite, chloride slag, slag fines and rutile, as well as pig iron and zircon. The Pigment segment primarily produces and markets TiO₂, and has production facilities in the United States, Australia, and the Netherlands. Corporate and Other is comprised of corporate activities and businesses that are no longer in operation, as well as electrolytic manufacturing and marketing operations, all of which are located in the United States.

Segment performance is evaluated based on segment operating profit (loss), which represents the results of segment operations before unallocated costs, such as general corporate expenses not identified to a specific segment, environmental provisions, net of reimbursements, related to sites no longer in operation, interest expense, other income (expense) and income tax expense or benefit.

22. Emergence from Chapter 11

On January 12, 2009, the petition date, Tronox Incorporated and certain of its subsidiaries (collectively, the “Debtors”) filed voluntary petitions in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) seeking reorganization relief under the provisions of Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 cases were consolidated for the purpose of joint administration.

On November 30, 2010 (the “Confirmation Date”), the Bankruptcy Court entered an order confirming the Debtors’ First Amended Joint Plan of Reorganization pursuant to Chapter 11 of the Bankruptcy Code, dated November 5, 2010 (as amended and confirmed, the “Plan”). Material conditions to the Plan were resolved during the period from the Confirmation Date until January 26, 2011, and subsequently, on February 14, 2011 (the “Effective Date”), the Debtors emerged from bankruptcy and continued operations as reorganized Tronox Incorporated.

On June 15, 2012, the reorganized Tronox Incorporated was combined with the mineral sands business of Exxaro in an integrated series of transactions whereby Tronox Limited became the parent company in a tax inversion transaction.

As of March 31, 2013, a motion granting a final decree closing the Chapter 11 cases has not been filed.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with Tronox Limited’s condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q, as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2012. This discussion contains forward-looking statements that involve risks and uncertainties, and actual results could differ materially from those discussed in the forward-looking statements as a result of numerous factors.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains certain financial measures, in particular the presentation of Income from Operations, EBITDA and Adjusted EBITDA, which are not presented in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). We are presenting these non-U.S. GAAP financial measures because they provide us and readers of this Form 10-Q with additional insight into our operational performance relative to earlier periods and relative to our competitors. We do not intend for these non-U.S GAAP financial measures to be a substitute for any U.S. GAAP financial information. Readers of these statements should use these non-U.S. GAAP financial measures only in conjunction with the comparable U.S. GAAP financial measures. A reconciliation of Income from Operations to Income from Continuing Operations, the most comparable U.S. GAAP measure is provided herein. A reconciliation of Net income to EBITDA and Adjusted EBITDA is also provided herein.

Executive Overview

We are a global leader in the production and marketing of titanium bearing mineral sands and titanium dioxide pigment (“TiO₂”). We are the third largest global producer and marketer of TiO₂manufactured via chloride technology, as well as the third largest global producer of titanium feedstock and a leader in global zircon production. We have operations in North America, Europe, South Africa and the Asia-Pacific region. We operate three TiO₂ facilities at the following locations: Hamilton, Mississippi; Botlek, the Netherlands; and Kwinana, Western Australia, representing approximately 465,000 tonnes of annual TiO₂ production capacity. Additionally, we operate three separate mining operations: KwaZulu-Natal (“KZN”) Sands located in South Africa, Namakwa Sands located in South Africa and Cooljarloo Sands located in Western Australia, which have a combined annual production capacity of approximately 753,000 tonnes of titanium feedstock and approximately 265,000 tonnes of zircon.

We have two reportable operating segments, Mineral Sands and Pigment. Corporate and other is comprised of our electrolytic manufacturing and marketing operations, as well as our corporate activities, including businesses that are no longer in operation.

The Mineral Sands segment includes the exploration, mining and beneficiation of mineral sands deposits. These operations produce titanium feedstock, including ilmenite, chloride slag, slag fines and rutile, as well as zircon and pig iron. Titanium feedstock is used primarily to manufacture TiO₂. Zircon is a mineral which is primarily used as an opacifier in ceramic glazes for tiles, plates, dishes and industrial products.

The pigment segment primarily produces and markets TiO₂. TiO₂ is used in a wide range of products due to its ability to impart whiteness, brightness and opacity. TiO₂is used extensively in the manufacture of paint and other coatings, plastics and paper and in a wide range of other applications, including inks, fibers, rubber, food, cosmetics and pharmaceuticals. TiO₂ is a critical component of everyday consumer applications due to its superior ability to cover or mask other materials effectively and efficiently relative to alternative white pigments and extenders. We believe that, at present, TiO₂ has no effective substitute because no other white pigment has the physical properties for achieving comparable opacity and brightness or can be incorporated in a cost-effective manner.

Acquisition of Mineral Sands Business

Because we believed that becoming vertically integrated would benefit us by assuring our access to critical supply, retaining cash and margin in the Company, and enabling general operating flexibility, we acquired a global producer of mineral sands with production facilities and sales and marketing presence strategically positioned throughout the world. Specifically, we acquired 74% of Exxaro Resources Ltd’s (“Exxaro”) South African mineral sands operations, including its Namakwa and KZN Sands mines, separation and slag furnaces, along with its 50% share of the Tiwest Joint Venture in Western Australia (together the “mineral sands business”) (the “Transaction”). On June 15, 2012, the date of the Transaction (the “Transaction Date”), the existing business of Tronox Incorporated was combined with the mineral sands business under Tronox Limited. As such, as of the Transaction Date, we own 100% of the operations formerly operated by the Tiwest Joint Venture.

Prior to the Transaction Date, Tronox Incorporated operated the Tiwest Joint Venture with Exxaro Australia Sands Pty Ltd., a subsidiary of Exxaro, which operated a chloride process TiO₂ plant located in Kwinana, Western Australia, a mining operation in Cooljarloo, Western Australia, and a mineral separation plant and a synthetic rutile processing facility, both in Chandala, Western Australia.

Recent Developments

Dividends Declared — On February 19, 2013, the Board declared a quarterly dividend of $0.25 per share which was paid on March 20, 2013 to holders of our Class A Shares and Class B Shares at close of business on March 6, 2013, totaling approximately $29 million. On May 7, 2013, the Board declared a quarterly dividend of $0.25 per share to holders of Class A Shares and Class B Shares, totaling approximately $29 million. See Note 14 of Notes to unaudited Condensed Consolidated Financial Statements.

Extinguishment of Debt — On February 28, 2013, we repaid the outstanding principal balance of $149 million, plus interest, related to the $150 million Senior Secured Delayed Draw Term Loan (the “Senior Secured Delayed Draw Term Loan”). See Note 11 of Notes to unaudited Condensed Consolidated Financial Statements.

Term Loan — On March 19, 2013, we entered into an Amended and Restated Credit and Guaranty Agreement (the “Amended and Restated Credit Agreement”). Pursuant to the Amended and Restated Credit Agreement, we obtained a $1.5 billion senior secured term loan (the “Term Loan”), which matures on March 19, 2020. See Note 11 of Notes to unaudited Condensed Consolidated Financial Statements.

Business Environment

The following discussion includes trends and factors that may affect future operating results.

Vertical Integration — Our integration plan is on track to more fully demonstrate the material cost advantages it gives us. The vertical integration of titanium feedstock and TiO₂ production provides us with a secure and cost competitive supply of high grade titanium feedstock over the long term. Our ability to supply all of the feedstock that our pigment operations require enables us to balance our consumption and sales in ways that we believe our competitors cannot. During the first quarter of 2013, titanium feedstock sold internally to the pigment segment increased. As a result, during the first quarter of 2013, we cancelled contracts with two external ore suppliers.

Mineral Sands — Titanium feedstock experienced a rise in selling prices during the first quarter of 2013, as a portion of legacy third-party sales contracts priced below market expired, while rutile and zircon pricing declined more modestly. We believe the market will strengthen particularly during the second half of 2013 and, as it does, our low cost position should enable us to achieve higher margins, significantly reduce earnings volatility and strong cash generation by selling feedstock indirectly into the market and by consuming feedstock at the cost of extraction and beneficiation for our pigment business.

Pigment — During the first quarter of 2013, we saw an increase of TiO₂ sales volumes from the fourth quarter of 2012 in all three major regions; however we saw a decrease in selling prices. We continue to anticipate the global market for pigment to strengthen in the second half of 2013.

Supply and Demand — During 2013, we expect to see sequential demand momentum in both the mineral sands and pigment businesses. Our vertical integration continues on plan with an increasing percentage of titanium feedstock used by our pigment business sourced internally from our mineral sands business.

Competition — We operate in highly competitive markets, and face competition not only from chloride process pigment producers, but also sulphate process pigment producers. Moreover, because transport costs are minor relative to the cost of our product, there is also some competition between products produced in one region versus products produced in another region.

Seasonality — The demand for TiO₂ during a given year is subject to seasonal fluctuations. Because TiO₂ is widely used in paint and other coatings, titanium feedstocks are in higher demand prior to the painting season (spring and summer in the Northern Hemisphere), and pig iron is in lower demand during the European summer holidays, when many steel plants and foundries undergo maintenance. Zircon generally is a non-seasonal product but is negatively impacted by the Chinese New Year holiday due to reduced zircon demand from China.

Currency Exchange Rates — The financial condition and results of operations of our operating entities in the Netherlands, Australia and South Africa are reported in various foreign currencies and then converted into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. As a result, any volatility of the U.S. dollar against these foreign currencies creates uncertainty for and may have a positive or negative impact on reported sales and operating results. Foreign currency effects appear in our financial statements in several ways. First, they impact reported amounts of revenues and expenses and are embedded in each line item of the financial statements. Second, for changes in reported asset and liability amounts, changes are reported in either other income (expense) on the unaudited Condensed Consolidated Statements of Operations or in cumulative translation adjustments in “Accumulated other comprehensive income (loss)” on the unaudited Condensed Consolidated Balance Sheets.

29

For the first quarter of 2013, the U.S. dollar strengthened approximately 8% against the South African Rand.

Environmental — We currently report and manage greenhouse gas (“GHG”) emissions as required by law for sites located in areas (European Union/Australia) requiring such managing and reporting. While the United States has not adopted any federal climate change legislation, the EPA has introduced some GHG programs. For example, under the EPA’s GHG “Tailoring Rule,” expansions or new construction could be subject to the Clean Air Act’s Prevention of Significant Deterioration (“PSD”) requirements. Some of our facilities are currently subject to GHG emissions monitoring and reporting. Changes or additional requirements due to GHG regulations could impact our capital and operating costs. However, it is not possible at the present time to estimate any financial impacts to these U.S. operating sites. Also, some in the scientific community believe that increasing concentrations of GHGs in the atmosphere may result in climatic changes. Depending on the severity of climatic changes, our operations could be adversely affected. The Western Australian operations are subject to a new Australian carbon tax law that went into effect in July 2012, resulting in an approximate $7 million impact annually.

Political and social unrest in South Africa — South Africa has been experiencing political and social unrest in several mining industries. Additionally, South Africa has been experiencing electricity interruptions due to labor unrest. Changes to or instability in the economic or political environment in South Africa or neighboring countries, especially if such changes create political instability, actual or potential shortages of production materials or labor unrest, could result in production delays and production shortfalls and materially impact our production and results of operations. We negotiate new labor contracts with the unions in South Africa annually. We consider relations with our employees to be stable.

We reported net sales for the first quarter of 2013 of $470 million, an increase of 8%. The increase in net sales for 2013 reflects the impact of the acquired businesses and higher volumes in the pigment business, partially offset by lower selling prices. The acquired businesses contributed $134 million to consolidated net sales during 2013. Higher volumes in the pigment business primarily reflect an increase in shipments to the Asia-Pacific region. Lower prices primarily resulted from softening market demand in the pigment business in late 2011 and early 2012, which accelerated in the latter half of 2012. The impact of foreign currency exchange rates increased net sales by $1 million during 2013 as compared to 2012.

Cost of goods sold for the first quarter of 2013 was $438 million, an increase of 58%. The increase principally reflects the inclusion of the acquired business, higher pigment production costs, primarily for raw materials and chemical products, higher per unit costs due to lower capacity utilization during 2013, and an increase in sales volumes. Cost of goods sold for 2013 includes $8 million of net non-cash amortization of inventory step-up and unfavorable ore sales contracts as a result of purchase accounting.

Our gross margin decreased $125 million during the first quarter of 2013 to 7% of net sales as compared to 36% of net sales in 2012. This decrease was principally due to higher input costs and lower selling prices in the pigment business. Net noncash amortization of $8 million as a result of purchase accounting impacted the 2013 gross margin by 2%.

Selling, general and administrative (“SG&A”) expenses were $51 million in the first quarter of 2013, an increase of $7 million or 16% during 2013 as compared to 2012. During 2013, the acquired business accounted for approximately $5 million of our total selling, general and administrative costs. The remaining net increase during 2013 compared to 2012 is primarily due to an increase in severance expense related to the departure of the chief financial officer and increased costs for corporate relocation, partially offset by a decrease related to share-based compensation awards.

Interest and debt expense for the first quarter of 2013 was $27 million, an increase of $19 million. The increase is primarily attributable to interest expense on the $900 million senior notes due 2020 (the “Senior Notes”) of $14 million during 2013, as well as the amortization of debt issuance costs associated with the Senior Notes of $1 million.

In February 2013, we repaid the outstanding principal balance of $149 million at par, plus interest, related to the $150 million Senior Secured Delayed Draw Term Loan. In accordance with ASC 470, Debt, the Company accounted for such repayment as an extinguishment of debt. As such, the Company recognized a loss on the early extinguishment of debt of $4 million related to the allocated portion of the unamortized original issue discount and debt issuance costs.

The negative effective tax rate for the three months ended March 31, 2013, differs from the Australian statutory rate of 30% primarily due to withholding tax accruals, valuation allowances in the United States, and income in foreign jurisdictions taxed at rates different than 30%. The effective tax rate for the three months ended March 31, 2012, differs from the U.S. statutory rate of 35% primarily due to valuation allowances in the United States and income in foreign jurisdictions taxed at rates different than 35%.

The Company continues to maintain a valuation allowance related to the net deferred tax assets in the United States. Future provisions for income taxes will include no tax benefits with respect to losses incurred and tax expense only to the extent of current alternative minimum tax and state tax payments until the valuation allowance in the United States is eliminated. ASC 740, Income Taxes, requires that all available positive and negative evidence be weighted to determine whether a valuation allowance should be recorded.

Operations Review of Segment Revenue and Profit

Net Sales

	Three Months Ended March 31,
	2013			2012			Variance
Mineral Sands segment	$	298		$	83		$	215
Pigment segment		288			362			(74	)
Corporate and other		27			31			(4	)
Eliminations		(143	)		(42	)		(101	)
Net Sales	$	470		$	434		$	36

Mineral Sands segment

Net sales increased $215 million during 2013 as compared to 2012. The increase is primarily attributable to the acquired business which, on a segment basis, contributed $241 million in revenue during 2013. The remaining decrease was primarily comprised of a $31 million decrease in selling prices, offset by a $6 million increase due to sales volume. Minerals Sands selling prices declined principally due to a depressed zircon market. Minerals sales volumes were higher primarily due to increased shipments of synthetic rutile to our pigments business, as we move towards full internal sourcing.

Pigment segment

Pigment segment net sales decreased $74 million, or 20% during 2013 as compared to 2012. The decrease is primarily due to a decrease in selling prices of $91 million, offset by higher volumes of $16 million. The volume impact reflects increased shipments to the Asia-Pacific region. The effect of changes in foreign currency positively impacted pigment net sales by $1 million.

Corporate and other

Net sales decreased $4 million, or 13% during 2013 as compared to 2012. Corporate and other includes our electrolytic manufacturing business. Electrolytic and other chemical products net sales were lower primarily due to lower volumes of sodium chlorate and electrolytic manganese dioxide (“EMD”), and to a lesser extent, lower selling prices for EMD.

Mineral Sands segment

Income from operations increased $45 million during 2013. The acquired businesses contributed $74 million to segment income from operations during 2013. The remaining decrease of $29 million during 2013 is primarily attributable to a $31 million decrease in selling prices, offset by higher volumes of $3 million. Cost of goods sold in the Mineral Sands segment in 2013, includes net noncash charges of $8 million related to purchase accounting adjustments for inventory step-up and unfavorable contract amortization.

Pigment segment

Income from operations decreased $177 million during 2013, which was primarily driven by lower selling prices of $91 million, and higher costs, principally for feedstock ores, and other chemicals of $75 million.

Non-U.S. GAAP Financial Measures

EBITDA and Adjusted EBITDA, which are used by management to measure performance, are non-U.S. GAAP financial measures. Management believes that EBITDA is useful to investors, as it is commonly used in the industry as a means of evaluating operating performance. EBITDA and Adjusted EBITDA are not recognized terms under U.S. GAAP and do not purport to be an alternative measure of our financial performance as determined in accordance with U.S. GAAP. Because other companies may calculate EBITDA and Adjusted EBITDA differently than we do, EBITDA and Adjusted EBITDA, as presented herein, may not be comparable to similarly titled measures reported by other companies.

Management believes these non-U.S. GAAP financial measures:

• Reflect our ongoing business in a manner that allows for meaningful period-to-period comparison and analysis of trends in our business, as they exclude income and expense that are not reflective of ongoing operating results;

• Provide useful information in understanding and evaluating our operating results and comparing financial results across periods;

• Provide an normalized view of our operating performance by excluding items that are either non-cash or non-recurring in nature;

• Enable investors to assess our compliance with financial covenants under our debt instruments; and

• Adjusted EBITDA is one of the primary measures management uses for planning and budgeting processes and to monitor and evaluate financial and operating results.

32

The following table reconciles net income to EBITDA and Adjusted EBITDA for the periods presented:

	Three Months Ended March 31,
	2013			2012
Net income	$	(45	)	$	86

(a) Includes noncash pension and postretirement costs, accretion expense, severance expense, transaction costs, and other non-recurring items.

Financial Condition and Liquidity

The following table provides information for the analysis of our historical financial condition and liquidity:

	March 31,		December 31,
	2013		2012
Cash and cash equivalents	$	1,375	$	716
Working capital (1)	$	2,330	$	1,706
Net debt (2)	$	1,036	$	929
Total assets	$	6,015	$	5,511
Total long-term debt	$	2,411	$	1,615

(1) Represents excess of current assets over current liabilities.

(2) Represents excess of debt over cash and cash equivalents.

As of March 31, 2013, our total liquidity was $1,748 million, which was comprised of $275 million available under the $300 million UBS Revolver (as defined below), $98 million available under the ABSA Revolver (as defined below) and $1,375 million in cash and cash equivalents. As of March 31, 2013, we had a $25 million of letter of credit issued against the UBS Revolver. In 2013, cash and cash equivalents increased $659 million, reflecting the refinancing of the $550 million Senior Secured Term Loan (the “Senior Secured Term Loan”) with a $1.5 billion Term Loan partially offset by cash used to repay the $150 million Senior Secured Delayed Draw Term Loan and the fees associated with the refinancing, as well as cash used in operations.

At March 31, 2013, we held cash and cash equivalents in the respective jurisdictions: $1,244 million in Australia, $73 million in the United States, $33 million in South Africa, and $25 million in Europe. Our credit facilities limit transfers of funds from subsidiaries in the United States to certain foreign subsidiaries. Foreign subsidiaries do not have limits on transferring funds to the United States or between themselves. We have in place intercompany financing agreements that enable the movement of cash to the United States, if needed.

The use of our cash will include servicing our interest and debt repayment obligations, making pension contributions and funding certain capital expenditures for innovative initiatives, productivity enhancements and maintenance and safety requirements.

Capital Resources

Short-Term Debt

We have a $300 million global senior secured asset-based syndicated revolving credit agreement with UBS AG (the “UBS Revolver”) and a R900 million (approximately $98 million as of March 31, 2013) revolving credit facility with ABSA Bank Limited acting through its ABSA Capital Division (the “ABSA Revolver”). At March 31, 2013, we had not drawn on either revolver. At March 31, 2013, the Company had outstanding letters of credit, bank guarantees and performance bonds of approximately $51 million, of which $25 million in letters of credit were issued under the UBS Revolver and $18 million were bank guarantees issued by ABSA.

See Note 11 of Notes to Consolidated Financial Statements for additional information related to our short-term and long-term debt.

Debt Covenants

At March 31, 2013, we were in compliance with our debt covenants. See Note 11 of Notes to Condensed Consolidated Financial Statements for additional information related to our debt covenants.

Cash Flows

The following table presents cash flow for the periods indicated:

	Three Months Ended March  31, 2013			Three Months Ended March  31, 2012
Cash used in operating activities		(1	)		(26	)
Cash used in investing activities		(45	)		(21	)
Cash provided by financing activities		710			111
Effects of exchange rate changes on cash and cash equivalents		(5	)		5
Net increase in cash and cash equivalents	$	659		$	69

Cash Flows from Operating Activities — Cash flows from operating activities for 2013 were a use of funds of $1 million compared to a use of funds of $26 million in 2012. The use of funds during 2013 was primarily attributable to cash used in operations, as well as increased accounts receivable and decreased accounts payable offset by a decrease in inventories.

Cash Flows from Investing Activities — Net cash provided by investing activities during 2013 reflects $45 million of capital expenditures. Capital expenditures for the remainder of 2013 are expected to be in the range of $175 million to $235 million.

Cash Flows from Financing Activities — Net cash provided by financing activities during 2013 of $710 million was comprised of the following:

Cash inflows:

• Refinancing of the Senior Secured Term Loan with the Term Loan resulting in a cash inflow of $945 million.

Cash outflows:

• Repayment of the Senior Secured Delayed Draw Term Loan of $149 million;

• Payment of debt issuance costs associated with the refinancing of the Senior Secured Term Loan with the Term Loan of $28 million,

• Repayment of the ABSA Revolver of $29 million;

• Repayment of other debt of $1 million; and

• Dividends paid of $29 million.

34

Contractual Obligations

The following table sets forth information relating to our contractual obligations as of March 31, 2013:

	Contractual Obligation Payments Due by Year
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Long-term debt and lease financing (including interest) (1)	$	3,209	$	142	$	289	$	280	$	2,498
Purchase obligations (2)		377		123		109		39		106
Operating leases		276		28		51		46		151
Total	$	3,862	$	293	$	449	$	365	$	2,755

(1) During the first quarter of 2013, we repaid the Senior Secured Delayed Draw and modified the Senior Secured Term Loan with a $1.5 billion Term Loan. We calculated the Term Loan interest at a base rate of 1% plus a margin of 3.5%. See Note 11 of Notes to unaudited Condensed Consolidated Financial Statements.

(2) Includes obligations to purchase requirements of process chemicals, supplies, utilities and services. During the first quarter of 2013, the Company terminated ore contracts with two suppliers.

Recent Accounting Pronouncements

See Note 3 of Notes to unaudited Condensed Consolidated Financial Statements for recently issued accounting pronouncements.

Environmental Matters

We are subject to a broad array of international, federal, state and local laws and regulations relating to safety, pollution, protection of the environment and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. In the ordinary course of business, we are subject to frequent environmental inspections and monitoring and occasional investigations by governmental enforcement authorities. Under these laws, we are or may be required to obtain or maintain permits or licenses in connection with our operations. In addition, under these laws, we are or may be required to remove or mitigate the effects on the environment of the disposal or release of chemical, petroleum, low-level radioactive and other substances at our facilities. We may incur future costs for capital improvements and general compliance under environmental, health and safety laws, including costs to acquire, maintain and repair pollution control equipment. Environmental laws and regulations are becoming increasingly stringent, and compliance costs are significant and will continue to be significant in the foreseeable future. There can be no assurance that such laws and regulations or any environmental law or regulation enacted in the future is not likely to have a material effect on our business. We are in compliance with applicable environmental rules and regulations. Currently, we do not have any outstanding notices of violations or orders from regulatory agencies.

At many of our operations, we comply with worldwide, voluntary standards developed by the International Organization for Standardization (“ISO”), a nongovernmental organization that promotes the development of standards and serves as a bridging organization for quality and environmental standards, such as ISO 9002 for quality management and ISO 14001 for environmental management.

In December 2006, the European parliament and European council approved a new European regulatory framework for chemicals called REACH. REACH took effect on June 1, 2007, and the program it establishes will be phased in over 11 years. The registration, evaluation and authorization phases of the program will require expenditures and resource commitments in order to, for example, participate in mandatory data-sharing forums; acquire, generate and evaluate data; prepare and submit dossiers for substance registration; obtain legal advice and reformulate products, if necessary.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market, credit, operational and liquidity risks in the normal course of business, which are discussed below. We manage these risks through normal operating and financing activities and, when appropriate, through the use of derivative instruments. We do not invest in derivative instruments for speculative purposes, but historically have entered into, and may enter into, derivative instruments for hedging purposes in order to reduce the exposure to fluctuations in interest rates, natural gas prices and exchange rates.

35

Commodity Price Risk

A substantial portion of our products and raw materials are commodities that reprice as market supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to vary with changes in the business cycle and are expected to do so in the near term as ore prices are expected to fluctuate over the next few years. The Company tries to protect against such instability through various business strategies. These include provisions in sales contracts allowing us to pass on higher raw material costs through timely price increases and formula price contracts to transfer or share commodity price risk.

Credit Risk

A significant portion of our liquidity is concentrated in trade accounts receivable that arise from sales of TiO₂ and titanium feedstock to customers in the TiO₂ industry. The industry concentration has the potential to impact the Company’s overall exposure to credit risk, either positively or negatively, in that its customers may be similarly affected by changes in economic, industry or other conditions. The Company performs ongoing credit evaluations of its customers, and uses credit risk insurance policies from time to time as deemed appropriate to mitigate credit risk but generally does not require collateral. The Company maintains allowances for potential credit losses based on historical experience. For the period ended March 31, 2013, the Company’s ten largest TiO₂ customers represented approximately 44% of its total TiO₂ net sales; however, no single customer accounted for more than 10% of total net sales.

Interest Rate Risk

Our exposure to interest rate risk is minimized by the fact that our $1.5 billion of floating rate debt includes a Libor floor of 1%. As such, Libor would need to increase from the rate in effect at March 31, 2013 to greater than 1% before our borrowing rate would increase. Using a sensitivity analysis as of March 31, 2013, a hypothetical 1% increase in interest rates would result in an increase to pre-tax income of approximately $10 million on an annualized basis. This is due to the fact that earnings on our floating rate financial assets of $1.4 billion at March 31, 2013 would increase by the full 1% while the interest expense on our floating rate debt would increase by less than the full 1%.

Foreign Exchange Risk

The Company manufactures and markets its products in a number of countries throughout the world and, as a result, is exposed to changes in foreign currency exchange rates, particularly in Australia, South Africa and the Netherlands. Costs in Australia and South Africa are incurred, primarily, in local currencies other than the U.S. dollar. In Australia and South Africa, the majority of our revenues are in U.S. dollars. In Europe, however, a majority of our revenues and costs are in the local currency creating a partial natural hedge. This leaves the Company exposed to movements in the Australian dollar and South African Rand versus the U.S. dollar. In order to manage this risk, we have from time to time entered into forward contracts to buy and sell foreign currencies as “economic hedges” for these foreign currency transactions. As of March 31, 2013, we did not have any forward contracts in place.

Item 4. Controls and Procedures

This quarterly report on Form 10-Q does not include a report of management’s assessment regarding internal controls over financial reporting or an attestation report of the Company’s registered public accounting firm due to a transition period established by the Securities and Exchange Commission (the “SEC”) for newly public companies.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, the Company may be party to a number of legal and administrative proceedings involving environmental and/or other matters in various courts or agencies. These proceedings, individually and in the aggregate, may have a material adverse effect on the Company. These proceedings may be associated with facilities currently or previously owned, operated or used by the Company and/or its predecessors, some of which may include claims for personal injuries, property damages, cleanup costs and other environmental matters. Current and former operations of the Company may also involve management of regulated materials, which are subject to various environmental laws and regulations including the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”), the Resource Conservation and Recovery Act (“RCRA”) or state equivalents. Similar environmental laws and regulations and other requirements exist in foreign countries in which the Company operates.

36

The Western Australia Office of State Revenue (the “OSR”) continues to review their technical position on the imposition of stamp duty on the transfer of Tronox Incorporated’s shares related to Kerr-McGee’s restructuring in 2002 and from the share transfer related to the spinoff of Tronox Incorporated from Kerr-McGee in 2005. On January 17, 2012, the OSR contacted the Company seeking additional information related to the 2005 spinoff. On October 20, 2012, the OSR rendered its assessment of $5 million, comprised of a primary stamp duty liability of $3 million and penalty tax of $2 million. The Company had accrued $3 million at December 31, 2012, which was recorded in “Trade and other payables” in the unaudited Condensed Consolidated Balance Sheets. As required by law, the Company paid the entire amount of the assessment in January 2013; however it has submitted an objection to the penalty, setting out the reasons that the Commissioner of State Revenue has erred in the imposition of the penalty. The decision is expected in respect of this matter in April 2013. If the objection is unsuccessful, the Company may appeal to the State Administrative Tribunal for review of the decision. The Company intends to exercise all its legal and administrative options in order to oppose the imposition of the penalty.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report, you should carefully consider the factors discussed “Risk Factors” included within our Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2012. The risks described in the Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. There have been no material changes from the risk factors disclosed under the heading “Risk Factors” in our Form 10-K.

RECITALS:

WHEREAS, reference is hereby made to (i) the Credit and Guaranty Agreement dated as of February 8, 2012 (as amended by that certain First Amendment to Credit and Guaranty Agreement dated as of May 11, 2012 and as further amended through the date hereof without giving effect to the amendments set forth in the Second Amendment (as defined below), the “Existing Credit Agreement”) by and among the Borrower, Holdings (as defined below), TRONOX INCORPORATED, a Delaware corporation (“US Holdings”), the subsidiaries of Holdings named therein or from time to time party thereto, the lenders party thereto, the Administrative Agent and the other agents named therein and (ii) the Second Amendment to Credit and Guaranty Agreement dated as of March 19, 2013 (the “Second Amendment”) by and among the Borrower, TRONOX LIMITED (ACN 153 348 111), an Australian public limited company incorporated in the Commonwealth of Australia (“Holdings”), the lenders party thereto, the Administrative Agent, and the guarantors listed on the signature pages thereto (capitalized terms used but not defined herein having the meaning provided in the Existing Credit Agreement, as amended by the Second Amendment (as may be further amended, restated, supplemented or otherwise modified from time to time, the “Restated Credit Agreement”)); and

WHEREAS, subject to the terms and conditions of the Second Amendment, the Additional Lender shall become a Lender under the Restated Credit Agreement pursuant to this Joinder Agreement;

NOW, THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows:

The Additional Lender hereby commits to make a Term Loan to the Borrower on the Second Amendment Effective Date in the amount of its “Additional Term Loan Commitment” set forth on its signature page hereto; provided that such amount may be reduced at the Administrative Agent’s discretion if the aggregate amount of all commitments received with respect to the Additional Term Loans exceeds the Additional Term Loan Amount (as defined in the Second Amendment) (such reduced amount, the “Allocated Amount”). Such Term Loan shall be provided subject to all of the terms and conditions set forth in the Second Amendment. Such Term Loans shall be entitled to all the benefits afforded by the Restated Credit Agreement and the other Credit Documents, and shall, without limiting the foregoing, benefit equally and ratably from each Guaranty and Liens created by the Collateral Documents. For the avoidance of doubt, the Additional Lender hereby consents to the Second Amendment.

¹  Each Additional Lender needs to sign a separate Joinder Agreement.

The Additional Lender (i) confirms that it has received a copy of the Second Amendment and the Restated Credit Agreement and the other Credit Documents, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender or Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Restated Credit Agreement; (iii) appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Restated Credit Agreement and the other Credit Documents as are delegated to the Administrative Agent and the Collateral Agent by the terms thereof, together with such powers and discretion as are reasonably incidental thereto; and (iv) agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Restated Credit Agreement are required to be performed by it as a Lender.

The Additional Lender acknowledges and agrees that upon its execution of this Agreement that as of the Second Amendment Effective Date, the Additional Lender shall become a “Lender” under, and for all purposes of, the Restated Credit Agreement and the other Credit Documents, and shall be subject to and bound by the terms thereof, and shall perform all the obligations of and shall have all rights of a Lender thereunder.

This Agreement may not be amended, modified or waived except by an instrument or instruments in writing signed and delivered on behalf of each of the parties hereto. This Agreement, the Restated Credit Agreement and the other Credit Documents constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all other prior agreements and understandings, both written and verbal, among the parties or any of them with respect to the subject matter hereof.

THIS AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as would be enforceable. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.

Earnings (Loss) Per Share

3 Months Ended

Mar. 31, 2013

Earnings (Loss) Per Share

17. Earnings (Loss) Per Share

Basic earnings (loss) per share is computed utilizing the two-class method, and is calculated based on weighted-average number of ordinary shares outstanding during the periods presented. Diluted earnings (loss) per share is computed using the weighted-average number of ordinary and ordinary equivalent shares outstanding during the periods utilizing the two-class method for nonvested restricted shares, warrants and options.

Certain unvested awards issued under the Tronox Limited Management Equity Incentive Plan and the T-Bucks Employee Participation Plan contain non-forfeitable rights to dividends declared on Class A Shares. Any unvested shares that participate in dividends are considered participating securities and are included in the Company’s computation of basic and diluted earnings per share using the two-class method, unless the effect of including such shares would be antidilutive. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of ordinary shares and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings.

The following table sets forth the number of shares utilized in the computation of basic and diluted earnings (loss) per share for the periods indicated. The weighted average shares outstanding, potentially dilutive shares, earnings per share and anti-dilutive shares have been restated to affect the 5-for-1 share split.

The Company

1. The Company

Tronox Limited, a public limited company registered under the laws of the State of Western Australia, Australia, and its subsidiaries (collectively referred to as “Tronox” or “the Company”) is a global leader in the production and marketing of titanium bearing mineral sands and titanium dioxide pigment (“TiO₂”). The Company’s world-class, high performance TiO₂ products are critical components of everyday applications such as paint and other coatings, plastics, paper and other applications. The Company’s mineral sands business consists primarily of two product streams—titanium feedstock and zircon. Titanium feedstock is primarily used to manufacture TiO_2. Zircon, a hard, glossy mineral, is used for the manufacture of ceramics, refractories, TV screen glass and a range of other industrial and chemical products. Tronox has global operations in North America, Europe, South Africa and Australia. The Company operates three TiO₂ facilities at the following locations: Hamilton, Mississippi, Botlek, the Netherlands, and Kwinana, Western Australia, representing approximately 465,000 tonnes of annual TiO₂ production capacity. Additionally, Tronox operates three separate mining operations: KwaZulu-Natal (“KZN”) Sands located in South Africa, Namakwa Sands located in South Africa and Cooljarloo located in Western Australia, which have a combined annual production capacity of approximately 753,000 tonnes of titanium feedstock and approximately 265,000 tonnes of zircon.

Tronox Limited was formed on September 21, 2011 for the purpose of the Transaction (defined below). Prior to the completion of the Transaction, Tronox Limited was wholly-owned by Tronox Incorporated, and had no operating assets or operations. On September 25, 2011, Tronox Incorporated, a Delaware corporation formed on May 17, 2005 (“Tronox Incorporated”), in preparation for the contribution and transfer by Kerr-McGee Corporation of certain entities, including those comprising substantially all its chemical business, entered into a definitive agreement (as amended, the “Transaction Agreement”) with Exxaro Resources Limited (“Exxaro”) and certain of its affiliated companies, to acquire 74% of its South African mineral sands operations, including its Namakwa and KZN Sands mines, separation facilities and slag furnaces, along with its 50% share of the Tiwest Joint Venture (together the “mineral sands business”) (the “Transaction”). On June 15, 2012, the date of the Transaction (the “Transaction Date”), 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 in a tax inversion transaction.

On May 4, 2012, Tronox Limited registered Class A ordinary shares (“Class A Shares”) to be issued to shareholders of Tronox Incorporated in connection with the completion of the Transaction. On the Transaction Date, Tronox Limited issued 9,950,856 Class B ordinary shares (“Class B Shares”) to Exxaro and one of its subsidiaries in consideration for the mineral sands business. Under the terms of the Transaction Agreement, Exxaro agreed that for a three-year period after the completion of the Transaction, it would not engage in any transaction or other action, that would result in its beneficial ownership of the voting shares of Tronox Limited to exceed 45% of the total issued shares of Tronox Limited. At March 31, 2013, Exxaro held approximately 44.4% of the voting securities of Tronox Limited.

Segment Information

21. Segment Information

Prior to the Transaction, Tronox Incorporated had one reportable segment representing its pigment business. The Pigment segment primarily produced and marketed TiO_2, and included heavy minerals production. The heavy minerals production was integrated with its Australian pigment plant, but also had third-party sales of minerals not utilized by its pigment operations. In connection with the Transaction, the Company acquired 74% of Exxaro’s South African mineral sands operations, including its Namakwa and KZN Sands mines, separation facilities and slag furnaces, along with its 50% share of the Tiwest Joint Venture in Western Australia. As such, the Company evaluated its new operations under ASC 280, Segments, and determined that the mineral sands operations qualify as a separate segment.

Subsequent to the Transaction, the Company has two reportable segments, Mineral Sands and Pigment. The Mineral Sands segment includes the exploration, mining and beneficiation of mineral sands deposits, as well as heavy mineral production. These operations produce titanium feedstock, including ilmenite, chloride slag, slag fines and rutile, as well as pig iron and zircon. The Pigment segment primarily produces and markets TiO₂, and has production facilities in the United States, Australia, and the Netherlands. Corporate and Other is comprised of corporate activities and businesses that are no longer in operation, as well as electrolytic manufacturing and marketing operations, all of which are located in the United States.

Segment performance is evaluated based on segment operating profit (loss), which represents the results of segment operations before unallocated costs, such as general corporate expenses not identified to a specific segment, environmental provisions, net of reimbursements, related to sites no longer in operation, interest expense, other income (expense) and income tax expense or benefit.

Emergence from Chapter 11

22. Emergence from Chapter 11

On January 12, 2009, the petition date, Tronox Incorporated and certain of its subsidiaries (collectively, the “Debtors”) filed voluntary petitions in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) seeking reorganization relief under the provisions of Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 cases were consolidated for the purpose of joint administration.

On November 30, 2010 (the “Confirmation Date”), the Bankruptcy Court entered an order confirming the Debtors’ First Amended Joint Plan of Reorganization pursuant to Chapter 11 of the Bankruptcy Code, dated November 5, 2010 (as amended and confirmed, the “Plan”). Material conditions to the Plan were resolved during the period from the Confirmation Date until January 26, 2011, and subsequently, on February 14, 2011 (the “Effective Date”), the Debtors emerged from bankruptcy and continued operations as reorganized Tronox Incorporated.

On June 15, 2012, the reorganized Tronox Incorporated was combined with the mineral sands business of Exxaro in an integrated series of transactions whereby Tronox Limited became the parent company in a tax inversion transaction.

As of March 31, 2013, a motion granting a final decree closing the Chapter 11 cases has not been filed.

Accounting for Cumulative Translation Adjustment

In March 2013, the Financial Accounting Standards Board (the “FASB”) issued accounting standards update (“ASU”) 2013-5, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-5”), which addresses the treatment of the cumulative translation adjustment into net income when a parent either sells its investment in a foreign entity or no longer holds controlling financial interest in a subsidiary or group of assets within a foreign entity.ASU 2013-5 is effective prospectively for periods beginning after December 15, 2013; however early adoption is permitted. The Company has not yet determined the impact, if any, that ASU 2013-5 will have on the consolidated financial statements.

Presentation of Comprehensive Income

During 2013, the Company adopted ASU 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires the presentation of the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, if the item is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The adoption of this guidance did not have a significant impact on the consolidated financial statements

Income Taxes

16. Income Taxes

The Company’s operations are conducted through its various subsidiaries in a number of countries throughout the world. The Company has provided for income taxes based upon the tax laws and rates in the countries in which operations are conducted and income is earned. For the three months ended March 31, 2013, Tronox Limited is the public parent registered under the laws of the State of Western Australia. For the three months ended March 31, 2012, Tronox Incorporated was the public parent, a Delaware corporation, registered in the United States.

Income tax provision	$	1		$	18
Income (Loss) before Income Taxes	$	(44	)	$	104
Effective tax rate		(2	)%		17	%

The negative effective tax rate for the three months ended March 31, 2013, differs from the Australian statutory rate of 30% primarily due to withholding tax accruals, valuation allowances in the United States, and income in foreign jurisdictions taxed at rates different than 30%. The effective tax rate for the three months ended March 31, 2012, differs from the US statutory rate of 35% primarily due to valuation allowances in the United States and income in foreign jurisdictions taxed at rates different than 35%.

The Company continues to maintain a valuation allowance related to the net deferred tax assets in the United States. Future provisions for income taxes will include no tax benefits with respect to losses incurred and tax expense only to the extent of current alternative minimum tax and state tax payments until the valuation allowance in the United States is eliminated. ASC 740, Income Taxes, requires that all available positive and negative evidence be weighted to determine whether a valuation allowance should be recorded.

On September 25, 2011, Tronox Incorporated entered into the Transaction Agreement with Exxaro to acquire the mineral sands business. The Company accounted for the Transaction under Accounting Standards Codification (“ASC”) 805, Business Combinations, (“ASC 805”). The excess of the fair value of the net assets acquired over the value of consideration was recorded as an initial bargain purchase gain.

The bargain purchase gain was not taxable for income tax purposes.

3. Recent Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (the “FASB”) issued accounting standards update (“ASU”) 2013-5, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-5”), which addresses the treatment of the cumulative translation adjustment into net income when a parent either sells its investment in a foreign entity or no longer holds controlling financial interest in a subsidiary or group of assets within a foreign entity.ASU 2013-5 is effective prospectively for periods beginning after December 15, 2013; however early adoption is permitted. The Company has not yet determined the impact, if any, that ASU 2013-5 will have on the consolidated financial statements.

During 2013, the Company adopted ASU 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires the presentation of the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, if the item is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The adoption of this guidance did not have a significant impact on the consolidated financial statements.

The UBS Revolver provides the Company with a committed source of capital with a principal borrowing amount of up to $300 million, subject to a borrowing base. In connection with its entry into the Amended and Restated Credit Agreement on March 19, 2013, the Company amended the UBS Revolver to allow for the increased size of the Term Loan over the Term Facility (see “Term Loan” below).

Term Facility

On February 8, 2012, Tronox Incorporated’s wholly-owned subsidiary, Tronox Pigments (Netherlands) B.V., entered into a term loan facility with Goldman Sachs Bank USA comprised of a $550 million Senior Secured Term Loan (the “Senior Secured Term Loan”) and a $150 million Senior Secured Delayed Draw Term Loan (the “Senior Secured Delayed Draw” together, the “Term Facility”). The Term Facility was issued net of an original issue discount of $7 million, or 1% of the initial principal amount, which is being amortized over the life of the Term Facility. On June 14, 2012, in connection with the closing of the Transaction, Tronox Pigments (Netherlands) B.V. drew down the $150 million Senior Secured Delayed Draw. In connection with obtaining the Term Facility, Tronox Incorporated incurred debt issuance costs of $17 million, which are recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets, and are being amortized through the maturity date.

On February 28, 2013, Tronox Pigments (Netherlands) B.V. repaid the outstanding principal balance of $149 million, plus interest, related to the $150 million Senior Secured Delayed Draw. In accordance with ASC 470, Debt, (“ASC 470”), the Company accounted for such repayment as an extinguishment of debt. As such, the Company recognized a loss on the early extinguishment of debt of $4 million related to the allocated portion of the unamortized original issue discount and debt issuance costs.

The Company allocated these amounts between the $550 million Senior Secured Term Loan and the $150 million Senior Secured Delayed Draw as follows:

	Outstanding Balance		Percentage of Outstanding Balance			Allocation of Unamortized Costs		Loss Extinguishment of Debt
Senior Secured Term Loan	$	547		79	%	$	16	$	—
Senior Secured Delayed Draw		149		21	%		4		4
Total	$	696		100	%	$	20	$	4

Term Loan

On March 19, 2013, Tronox Pigments (Netherlands) B.V., Tronox Limited, and certain subsidiaries of Tronox Limited named as guarantors, entered into an Amended and Restated Credit and Guaranty 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 Amended and Restated Credit Agreement, the Company obtained a $1.5 billion senior secured term loan (the “Term Loan”), which matures in March 2020. The terms of the Amended and Restated Credit Agreement are substantially similar to the Company’s prior Term Facility. The Term Loan was issued net of an original issue discount of $7 million, or 0.5% of the principal balance.

In accordance with ASC 470, the outstanding principal balance of the Senior Secured Term Loan of $547 million, which became part of the Term Loan, was accounted for as a debt modification. As such, the unamortized original issue discount of $5 million and debt issuance costs of $11 million related to the Term Facility will continue to be amortized over the life of the Term Loan.

The Term Loan bears interest at a base rate plus the applicable margin of 2.5% per annum, or adjusted Eurodollar rate plus the applicable margin of 3.5% per annum. The base rate is defined as the greater of (i) the prime lending rate as quoted in the print edition of The Wall Street Journal or (ii) the Federal Funds Effective rate in effect on such day plusone half of 1%; provided, however, that the Base Rate is not less than 2% per annum.

Additionally, in connection with obtaining the Term Loan, the Company incurred debt issuance costs of $28 million, which are recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets, and are being amortized through the maturity date. For the three month ended March 31, 2013, amortization expense amounted to less than $1 million.

Senior Notes

On August 20, 2012, Tronox Limited’s wholly-owned subsidiary, Tronox Finance LLC, issued $900 million aggregate principal amount of 6.375% senior notes due 2020 (the “Senior Notes”). The Senior Notes were 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. The Senior Notes bear interest semiannually at a rate equal to 6.375% and were sold at par value. The Senior Notes are fully and unconditionally guaranteed on a senior, unsecured basis by Tronox Limited and certain of its subsidiaries. The Senior Notes are redeemable at any time at the Company’s discretion. The Senior Notes and related guarantees have not been registered under the Securities Act, or any state securities laws, and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws.

The Company recorded debt issuance fees of $18 million, which are being amortized over the life of the debt, and are included in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets. During the three months ended March 31, 2013, amortization expense amounted to $1 million.

Exit Financing Facility

On February 14, 2011, Tronox Incorporated’s senior secured super-priority DIP and Exit Credit Agreement with Goldman Sachs Lending Partners, in accordance with its terms, converted into a $425 million exit facility with a maturity date of October 21, 2015 (the “Exit Financing Facility”). On February 8, 2012, Tronox Incorporated refinanced the Exit Facility with the Term Facility, as discussed above. In connection with the refinancing, the Company repaid $421 million.

Co-generation Unit Financing Arrangement

In March 2011, in order to finance its share of the asset purchase for the Tiwest Joint Venture, Tronox Incorporated incurred debt totaling $8 million. In connection with the Transaction, the Company acquired the remaining 50% undivided interest in the co-generation plant from Exxaro, along with its debt of $6 million. Under the financing arrangement, monthly payments are required, and interest accrues on the outstanding balance at the rate of 6.5% per annum. During the three months ended March 31, 2013, the Company made principal repayments of approximately $1 million.

Lease Financing

In connection with the Transaction, the Company acquired capital lease obligations in South Africa, which are payable through 2032 at a weighted average interest rate of approximately 17%. At March 31, 2013, such obligations had a net book value of assets recorded under capital leases aggregating $8 million. During 2013, the Company made payments of less than $1 million.

Fair Value

The Company’s debt is recorded at historical amounts. At March 31, 2013, the fair value of the Term Loan and Senior Notes was $1,523 million and $882 million, respectively. The Company determined the fair value of both the Senior Notes and the Term Loan using the Bloomberg market price as of March 31, 2013. At December 31, 2012, the fair value of the Senior Notes and the Term Facility was $910 million and $709 million, respectively. The fair value hierarchy for long-term debt is a Level 2 input.

Debt Covenants

At March 31, 2013, the Company had financial covenants in the UBS Revolver, the ABSA Revolver and the Term Loan.

The terms of the Amended and Restated Credit Agreement are substantially similar to the Company’s prior Credit and Guaranty Agreement with Goldman Sachs Bank USA, dated February 8, 2012, except that the Amended and Restated Credit Agreement (i) eliminates financial maintenance covenants (ii) permits, subject to certain conditions, incurrence of additional senior secured debt up to a leverage ratio of 2:1, (iii) increases the Company’s ability to incur debt in connection with permitted acquisitions and its ability to incur unsecured debt, and (iv) allows for the payment of a $0.25 per share dividend each fiscal quarter . Otherwise, the terms of the Amended and Restated Credit Agreement provide for customary representations and warranties, affirmative and negative covenants and events of default. The terms of the covenants, subject to certain exceptions, restrict, among other things: (i) debt incurrence; (ii) lien incurrence; (iii) investments, dividends and distributions; (iv) disposition of assets and subsidiary interests; (v) acquisitions; (vi) sale and leaseback transactions; and (vii) transactions with affiliates and shareholders.

The Term Facility 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. At March 31, 2013, only the ABSA Revolver had a financial maintenance covenant. The Company was in compliance with its financial covenants at March 31, 2013.

The Company has pledged the majority of our U.S. assets and certain assets of its non-U.S. subsidiaries in support of its outstanding debt.

Commitments and Contingencies

13. Commitments and Contingencies

Purchase Commitments—At March 31, 2013, purchase commitments were $99 million for the remainder of 2013, $95 million for 2014, $33 million for 2015, $20 million for 2016, $19 million for 2017 and $111 million thereafter.

Letters of Credit—At March 31, 2013, the Company had outstanding letters of credit, bank guarantees and performance bonds of approximately $51 million, of which $25 million in letters of credit were issued under the UBS Revolver and $18 million were bank guarantees issued by ABSA.

Legal—The Western Australia Office of State Revenue (the “OSR”) continues to review their technical position on the imposition of stamp duty on the transfer of Tronox Incorporated’s shares related to Kerr-McGee’s restructuring in 2002 and from the share transfer related to the spinoff of Tronox Incorporated from Kerr-McGee in 2005. On January 17, 2012, the OSR contacted the Company seeking additional information related to the 2005 spinoff. On October 20, 2012, the OSR rendered its assessment of $5 million, comprised of a primary stamp duty liability of $3 million and penalty tax of $2 million. The Company had accrued $3 million at December 31, 2012, which was recorded in “Trade and other payables” in the unaudited Condensed Consolidated Balance Sheets. As required by law, the Company paid the entire amount of the assessment in January 2013; however it has submitted an objection to the penalty, setting out the reasons that the Commissioner of State Revenue has erred in the imposition of the penalty. The decision is expected in respect of this matter in 2013. If the objection is unsuccessful, the Company may appeal to the State Administrative Tribunal for review of the decision. The Company intends to exercise all its legal and administrative options in order to oppose the imposition of the penalty.

Environmental Contingencies—In accordance with ASC 450, Contingencies, the Company recognizes a loss and records an undiscounted liability when litigation has commenced or a claim or an 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 estimated. It is not possible for the Company to reliably estimate the amount and timing of all future expenditures related to environmental matters because, among other reasons, environmental laws and regulations, as well as enforcement policies and clean up levels, are continually changing, and the outcome of court proceedings, alternative dispute resolution proceedings (including mediation) and discussions with regulatory agencies are inherently uncertain.

The Company believes that it has reserved adequately for the probable and reasonably estimable costs of known contingencies. There is no environmental litigation, claim or assessment that has been asserted nor is there any probability of an assessment or a claim for which the Company has not recorded a liability. However, additions to the reserves may be required as additional information is obtained that enables the Company to better estimate its liabilities. The Company cannot reliably estimate the amount of future additions to the reserves at this time. In certain situations, reserves may be probable but not estimable. Additionally, sites may be identified in the future where the Company could have potential liability for environmental related matters. If a site is identified, the Company will evaluate to determine what reserve, if any, should be established.

Other Matters—From time to time, the Company may be party to a number of legal and administrative proceedings involving environmental and/or other matters in various courts or agencies. These proceedings, individually and in the aggregate, may have a material adverse effect on the Company. These proceedings may be associated with facilities currently or previously owned, operated or used by the Company and/or its predecessors, some of which may include claims for personal injuries, property damages, cleanup costs and other environmental matters. Current and former operations of the Company may also involve management of regulated materials, which are subject to various environmental laws and regulations including the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”), the Resource Conservation and Recovery Act (the “RCRA”) or state equivalents. Similar environmental laws and regulations and other requirements exist in foreign countries in which the Company operates.

Share-based Compensation

18. Share-based Compensation

Compensation expense related to restricted share awards was $2 million and $6 million for the three months ended March 31, 2013 and 2012, respectively. Compensation expense related to the Company’s nonqualified option awards was $2 million and $1 million for the three months ended March 31, 2013 and 2012, respectively.

At March 31, 2013, unrecognized compensation expense related to the Company’s restricted shares and options, adjusted for estimated forfeitures, was approximately $54 million, with such unrecognized compensation expense expected to be recognized over a weighted-average period of approximately three years. The ultimate amount of such expense is dependent upon the actual number of restricted shares and options that vest. The Company periodically assesses the forfeiture rates used for such estimates. A change in estimated forfeiture rates would cause the aggregate amount of compensation expense recognized in future periods to differ from the estimated unrecognized compensation expense above.

Tronox Limited Management Equity Incentive Plan

On the Transaction Date, Tronox Limited adopted the Tronox Limited Management Equity Incentive Plan (the “Tronox Limited MEIP”), which permits the grant of awards that constitute incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards and other share-based awards, cash payments and other forms such as the compensation committee of the Board in its discretion deems appropriate, including any combination of the above. 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 the three months ended March 31, 2013, the Company granted 708,908 restricted share awards to employees, which have both time requirements and performance requirements. The time provisions are graded vesting, while the performance provisions are cliff vesting and have a variable payout. During the three months ended March 31, 2013, the Company granted 71,732 restricted share awards with graded vesting to members of the Board. In accordance with ASC 718, Compensation – Share-Based Compensation (“ASC 718”), the restricted share awards issued during the three months ended March 31, 2013 are classified as equity awards and are accounted for using the fair value established at the grant date.

Restricted share activity was as follows:

	Number of Shares			Fair Value(1)
Balance at December 31, 2012		761,065		$	20.62
Awards granted		780,640			20.96
Awards earned		(27,053	)		24.15
Awards forfeited		(10,242	)		24.99
Balance at March 31, 2013		1,504,410		$	20.70
Outstanding awards expected to vest		1,467,939		$	20.67

(1) Represents the weighted-average grant-date fair value.

Options

On February 25, 2013 and March 11, 2013, the Company granted 1,545,662 and 8,238 options, respectively, to employees to purchase Class A Shares, which vest over a three year period.

Options activity was as follows:

	Number of Options			Price (1)		Contractual Life Years (1)		Intrinsic Value(2)
Balance at December 31, 2012		528,759		$	25.16		9.38	$	—
Options issued		1,553,900			19.10		9.91		—
Options forfeited		(3,723	)		24.60		—		—
Options vested		(51,632	)		23.41		—		—
Outstanding at March 31, 2013		2,027,304		$	20.56		9.74	$	1,113,652
Outstanding awards expected to vest		1,923,034		$	20.55		9.75	$	1,065,208

(1) Represents weighted average exercise price and weighted average remaining contractual life, as applicable.

(2) Reflects aggregate intrinsic value based on the difference between the market price of the Company’s shares at March 31, 2013 and the options’ exercise price.

Grants

Valuation and Cost Attribution Methods. Options’ fair value are determined on the date of grant 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 necessary to earn the awards, which is the vesting period. The Company ran the Black-Scholes option-pricing model for the 1,545,662 options granted on February 25, 2013 and the 8,238 options granted on March 11, 2013 using the following assumptions:

	February 25, 2013			March 11, 2013
Risk-free interest rate		1.04	%		1.19	%
Expected dividend yield		5.24	%		4.65	%
Expected volatility		56	%		56	%
Expected term (years)		10			10
Per-unit fair value of options granted	$	6.28		$	7.48

For the February 25, 2013 grant, the Company used the fair market value and exercise price of $19.09, which was the adjusted closing price of Class A Shares, New York Stock Exchange symbol TROX, recorded on February 25, 2013. For the March 11, 2013 grant, the Company used the fair market value and exercise price of $21.49, which was the adjusted closing price of Class A Shares, New York Stock Exchange symbol TROX, recorded on March 11, 2013.

Risk-free interest rate — The Company used a risk-free interest rate of 1.04% and 1.19% for the February 25, 2013 grant and the March 11, 2013 grant, respectively, which was the risk-free interest rate based on U.S. Treasury Strips available with maturity period consistent with expected life assumption.

Expected Volatility — In setting the volatility assumption, the Company considered the most recent reported volatility of each compensation peer company. For the 2013 valuation, the peer company group included the following companies: Albemarle, Cabot Corporation, Celanese Corporation, Chemtura Corporation, Cliffs Natural Resources Inc., Cytec Industries Inc., Dupont, Eastman Chemical Company, Freeport-McMoRan Copper & Gold Inc., Huntsman Corporation, Kronos Worldwide, Inc., Rockwood Holdings, Inc., Southern Copper Corporation, and Teck Resources Limited.

T-Bucks Employee Participation Plan (“T-Bucks EPP”)

At March 31, 2013 and December 31, 2012, there were 548,234 shares in the trust with a fair value of $25.79, which represents the fair value on the date of purchase by the trust. Compensation expense during the three months ended March 31, 2013 was $1 million.

Long-Term Incentive Plan

In connection with the Transaction, the Company assumed 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 remeasured to fair value at each reporting date. At March 31, 2013, the LTlP plan liability was approximately $3 million, which is recorded in “Other long-term liabilities” on the unaudited Condensed Consolidated Balance Sheets. During the three months ended March 31, 2013, compensation expense was less than $1 million.

Tronox Incorporated Management Equity Incentive Plan

In connection with its emergence from bankruptcy, Tronox Incorporated adopted the Tronox Incorporated management equity incentive plan (the “Tronox Incorporated MEIP”), which permitted the grant of awards that constitute incentive options, nonqualified options, share appreciation rights, restricted share, restricted share units, performance awards and other share-based awards, cash payments and other forms such as the compensation committee of the Tronox Incorporated Board of Directors in its discretion deems appropriate, including any combination of the above. The number of shares available for delivery pursuant to the awards granted under the Tronox Incorporated MEIP was 1.2 million shares.

On the Transaction Date, 748,980 restricted shares of Tronox Incorporated vested in connection with the Transaction. The remaining restricted shares of Tronox Incorporated were converted to Tronox Limited restricted shares. Additionally, on the Transaction Date, 517,330 Tronox Incorporated options were converted to Tronox Limited options.

Restricted Shares

During the three months ended March 31, 2012, the Company granted to its employees 50,415 shares, which have graded vesting provisions. The Company is withholding the highest combined maximum rate imposed under all applicable federal, state, local and foreign tax laws on behalf of the employees that have received these awards. In accordance with ASC 718, such restricted stock awards were classified as liability awards and were remeasured to fair value at each reporting date.

Restricted share activity with employees and directors was as follows:

	Number of Shares			Fair Value
Balance at December 31, 2011		1,177,995		$	21.48
Awards granted		50,415			24.03
Awards earned		(61,165	)		34.85
Balance at March 31, 2012		1,167,245		$	28.26

Options

Tronox Incorporated options activity was as follows:

	Number of Options		Price (1)		Contractual Life Years (1)		Intrinsic Value(2)
Balance at December 31, 2011		345,000	$	22.00		9.95	$	0.7
Options issued		22,330		24.60		9.76		0.2
Outstanding at March 31, 2012		367,330	$	22.16		9.71	$	4.7

(1) Represents weighted average exercise price and weighted average remaining contractual life, as applicable.

(2) Reflects aggregate intrinsic value based on the difference between the market price of the Company’s shares at March 31, 2012 and the options’ exercise price.

2. Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited, and have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The December 31, 2012 balance sheet was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP for complete financial statements.

The unaudited condensed consolidated balance sheets as of March 31, 2013 and December 31, 2012 relate to Tronox Limited. The unaudited condensed consolidated statements of operations and cash flows for the three months ended March 31, 2013 reflect the consolidated operating results of Tronox Limited. The unaudited condensed consolidated statements of operations and cash flows for the three months ended March 31, 2012 reflect the consolidated operating results of Tronox Incorporated.

Prior to the Transaction Date, Tronox Incorporated operated the Tiwest Joint Venture with Exxaro Australia Sands Pty Ltd. The Tiwest Joint Venture was a contractual relationship between Tronox Incorporated and Exxaro whereby each party held an undivided interest in each asset of the joint venture, and each party was proportionally liable for each of the joint venture’s liabilities. The Tiwest Joint Venture was not a separate legal entity and did not enter into any transactions. Transactions were entered into by the joint venture partners who had the right to sell their own product, collect their proportional share of the revenues and absorb their share of costs. As such, Tronox Incorporated did not account for the Tiwest Joint Venture under the equity method. Instead, Tronox Incorporated accounted for its share of the Tiwest Joint Venture’s assets that were jointly controlled and its share of liabilities for which it was jointly responsible on a proportionate gross basis in its unaudited Condensed Consolidated Balance Sheet. Additionally, Tronox Incorporated accounted for the revenues generated from its share of the products sold and its share of the expenses of the joint venture on a gross basis in its unaudited Condensed Consolidated Statements of Operations. As of the Transaction Date, the Company owns 100% of the Tiwest Joint Venture operations. As such, the unaudited Condensed Consolidated Balance Sheets at March 31, 2013 and December 31, 2012 includes 100% of the Tiwest operations assets and liabilities. The unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2013 reflect 100% of the revenue and expenses of the Tiwest operations, while the unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2012 reflects Tronox Incorporated’s revenues generated from its share of the products sold and its share of the expenses of the joint venture on a gross basis.

In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation. 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 within one year of the date of the financial statements due to one or more future confirming events could have a material effect on the financial statements. The consolidated results of operations for interim periods are not necessarily indicative of results for the entire year.

Certain prior period amounts have been reclassified to conform to the manner and presentation in the current period. Such reclassifications did not have an impact on the Company’s net income or consolidated results of operations.

Asset Retirement Obligations

Asset Retirement Obligations

12. Asset Retirement Obligations

To the extent a legal obligation exists, an asset retirement obligation (“ARO”) is recorded at its 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 Tronox’s credit-adjusted risk-free interest rate. The Company classifies accretion expense related to asset retirement obligations as a production cost, which is included in “Cost of goods sold” on the unaudited Condensed Consolidated Statements of Operations.

The Company’s AROs are as follows:

• the KZN mine and the Namakwa Sands mine, both in South Africa, to restore the areas that have been disturbed as required under the mining leases;

• decommissioning on wet and dry separation plants and smelting operations in South Africa;

• mine closure and rehabilitation costs in Western Australia to restore the area that has been disturbed, as required under the mining lease;

• plant closure and exit costs associated with certain industrial sites in Western Australia, whereby the Company is required to return the sites to their original states under licensing conditions;

• plant closure and exit costs associated with the Botlek, the Netherlands facility, whereby the Company is required to return the site back to its original state at the end of its long-term lease; and

• landfill closure costs at the Hamilton, Mississippi facility to address one-time closure costs (cap with liner and cover with soil) and annual monitoring costs of the closed landfill under applicable state environmental laws in Mississippi.

The changes in AROs during the three months ended March 31, 2013 were as follows:

Environmental Rehabilitation Trust

The Company has established an environmental rehabilitation trust in respect of the prospecting and mining operations in South Africa in accordance with applicable regulations. The trustees of the fund are appointed by the Company, and consist of sufficiently qualified Tronox Limited employees capable of fulfilling their fiduciary duties. The environmental rehabilitation trust receives, holds, and invests funds for the rehabilitation or management of negative environmental impacts associated with mining and exploration activities. The contributions are aimed at providing sufficient funds at date of estimated closure of mining activities to address the rehabilitation and environmental impacts. Funds accumulated for a specific mine or exploration project can only be utilized for the rehabilitation and environmental impacts of that specific mine or project. Currently, the funds are invested in highly liquid, short-term instruments; however, the investment growth strategy has not been finalized. If a mine or exploration project withdraws from the fund for whatever valid reason, the funds accumulated for such mine or exploration project are transferred to a similar fund approved by management. At March 31, 2013 and December 31, 2012, the environmental rehabilitation trust assets were $19 million and $20 million, respectively, which were recorded in “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheets.
