Note 1: Description of the Business

The accompanying unaudited interim condensed combined financial statements (“Interim Condensed Combined Financial Statements”) include the historical accounts of the Alkali Chemicals Business (collectively referred to as “Alkali”, “Tronox Alkali Ltd.”, “We”, “Us”, “Our” or the “Company”) of Tronox Limited (the “Parent” or “Tronox”), a public limited company registered under the laws of the State of Western Australia, Australia. On April 1, 2015 Tronox completed the acquisition of Alkali from FMC Corporation (“FMC”) for an aggregate purchase price of $1,650.0 in cash and debt.

Nature of Operations

The Company mines and processes trona ore and manufactures natural soda ash and inorganic chemical products that include sodium bicarbonate, sodium sesquicarbonate and caustic soda (collectively referred to as “alkali products”). The alkali products are used in a variety of industries for glass manufacturing, water treatment, pulp and paper, textiles, food and pharmaceuticals and cosmetics. The alkali products are sold directly to various domestic and international customers as well as to the American Natural Soda Ash Corporation (“ANSAC”), the primary export customer of the Company. ANSAC is a third-party nonprofit corporation whose purpose is to promote export sales of U.S. produced soda ash in conformity with the Webb-Pomerene Act. All mining and processing activities of the Company take place at the facility located in the Green River Basin of Wyoming, United States. See Note 5 within these Interim Condensed Combined Financial Statements for additional information related to ANSAC.

Note 2: Basis of Presentation

Throughout the periods covered by the accompanying Interim Condensed Combined Financial Statements, Alkali operated as a business unit of Tronox. Consequently, standalone financial statements were not historically prepared for Alkali. The Interim Condensed Combined Financial Statements have therefore been derived from the accounting records of the Parent to present the Alkali historical carve-out interim condensed combined financial position as of March 31, 2017 and December 31, 2016 and its results of operations, changes in Parent company equity and cash flows for the three months ended March 31, 2017.

The Interim Condensed Combined Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. The Interim Condensed Combined Financial Statements include the assets, liabilities, revenues and expenses of Alkali, as carved out from the historical results of operations and the historical bases of assets and liabilities of the Parent, adjusted to conform to U.S. GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These Interim Condensed Combined Financial Statements do not represent complete financial statements and should be read in conjunction with the Annual Combined Financial Statements for the years ended December 31, 2016 and 2015, collectively referred to as the “Annual Combined Financial Statements.”

As the Interim Condensed Combined Financial Statements present Alkali as a carve-out business derived from the historical records of the Parent, net investment of Parent is shown in lieu of shareholders’ equity on the Interim Condensed Combined Balance Sheets. With the exception of certain payables, intercompany balances and transactions between Alkali and Tronox have been presented in Net investment of Parent. Intracompany balances and accounts within Alkali have been eliminated. Net investment of Parent represents Tronox’s interest in the recorded net assets of Alkali.

The Interim Condensed Combined Statements of Operations include all revenues and costs directly attributable to Alkali, as well as costs for certain functions and services used by Alkali. Therefore, certain costs related to Alkali have been allocated from the Parent. These allocated costs are primarily related to certain governance and corporate functions such as legal, investor relations, communications and

(In millions)

administration. The costs associated with these services and support functions have been allocated to Alkali primarily through specific identification or a pro-rata allocation using net sales. The net costs allocated for these functions are included in Selling, general and administrative expenses within the Interim Condensed Combined Statements of Operations.

For purposes of the Interim Condensed Combined Financial Statements, the income tax expense and deferred tax balances have been estimated as if we filed income tax returns stand-alone basis separate from Tronox.

The expense and cost allocations have been determined on a basis considered by management to be a reasonable reflection of the utilization of services both provided to and received by Alkali relative to the total costs incurred by Tronox. Additionally, the assets and liabilities assigned from Tronox have been deemed attributable to and reflective of the historical operations of Alkali. The Interim Condensed Combined Financial Statements of the Company do not present the Parent’s historical debt or related interest expense. However, the amounts recorded may not be representative of the amounts that would have been incurred had Alkali been an entity that operated independently of Tronox. Consequently, the Interim Condensed Combined Financial Statements may not be indicative of Alkali’s future performance and do not necessarily reflect what its results of operations, financial position and cash flows would have been had Alkali operated as a separate entity apart from Tronox during the periods presented. See Note 5 for further discussion of cost allocations included in the Interim Condensed Combined Financial Statement.

Components may not sum to total due to rounding.

Note 3: Summary of Significant Accounting Policies

Our significant accounting policies are those that we believe are important to the portrayal of our financial condition and results of operations, as well as those that involve significant judgments or estimates about matters that are inherently uncertain. There have been no material changes to the significant accounting policies as discussed in Note 3 of our Annual Combined Financial Statements.

Note 4: Recent Accounting Pronouncements

In addition to the accounting standards discussed in the Annual Combined Financial Statements, management assessed the impact of the following recently issued accounting standards:

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (“ASU 2017-07”) which amends the requirements in ASC 715, Compensation - Retirement Benefits, which requires employers that sponsor defined benefit pension and/or other postretirement plans to aggregate the various components of net periodic benefit cost for presentation purposes but does not prescribe where they should be presented in the income statement. ASU 2017-07 requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from service rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. Employers will have to disclose the line item(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted as of the beginning of an annual period for which an entity’s financial statements (interim or annual) have not been issued. ASU 2017-07 requires the presentation of the components of net periodic benefit cost in the income statement retrospectively while the guidance limiting the capitalization of net periodic benefit cost in assets to the service component will be applied prospectively. We have not yet determined the impact, if any, that ASU 2017-07 will have on our Interim Condensed Combined Financial Statements.

Note 5: Agreements and Transactions with Related Parties and Affiliates

Shared Services and Corporate Costs

We benefit from certain governance and corporate services provided by the Parent, including legal, investor relations, communications and administration. The amount of cost allocated to us by the Parent for these services was $4.9 for the three months ended March 31, 2017 and $4.3 for the three months ended March 31, 2016. These Parent allocations were determined through either specific identification or a pro-rata allocation using net sales and are included within Selling, general and administrative expenses within the Interim Condensed Combined Statements of Operations.

Stock-Based Compensation

During the period, employees of the Company were eligible to participate in the Tronox Limited Management Equity Incentive Plan (the “MEIP”), which permits the grant of awards that are comprised of incentive options, nonqualified options, share appreciation rights, restricted shares, restricted share units, performance awards and other share-based awards, cash payments and other forms as the compensation committee of the Board of Directors of Tronox (the “Board”) in its discretion deems appropriate, including any combination of the above.

The Company recorded stock-compensation expense related to the MEIP of $0.5 and $0.1 for the three months ended March 31, 2017 and 2016. None of the awards vested in 2017 or 2016 and therefore no income tax benefit was recorded for either period. Stock compensation expense is included within in Selling, general and administrative expenses within the Interim Condensed Combined Statements of Operations.

Cash Management, Financing and Financial Instruments

Tronox uses a centralized approach to cash management and the financing of its operations. The available cash balances of Alkali are regularly “swept” at the discretion of Tronox with Tronox funding Alkali’s operating and investing activities as needed. Transfers and distributions of cash between Alkali and Tronox are included within Net investment of Parent on the Interim Condensed Combined Balance Sheets.

Agreements and Transactions with Affiliates

We hold a membership in ANSAC, which is responsible for promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. Costs incurred by ANSAC are charged directly to us and included within Selling, general and administrative expenses. These costs include sales and marketing, salaries, benefits, office supplies, professional fees, travel, rent and certain other costs. These transactions do not necessarily represent arm’s length transactions and may not represent all costs if we operated on a stand-alone basis. We also benefit from favorable shipping rates for our direct exports when using ANSAC to arrange for ocean transport. Net sales to ANSAC were $74.8 and $60.4 for the three months ended March 31, 2017 and 2016. The costs charged to us by ANSAC, included in Selling, general and administrative, were $0.6 and $2.6 for the three months ended March 31, 2017 and 2016.

Receivables from related parties and affiliates as of March 31, 2017 and December 31, 2016 are as follows:

Note 6: Restructuring expense

In March 2017, the Company business announced a cost improvement initiative which focused on process improvements at our Wyoming facility (the “Wyoming Restructure”). During the three months ended March 31, 2017, we recorded $1.2 of restructuring costs related to the Wyoming Restructure, which was recorded in restructuring expense in the Interim Condensed Combined Statements of Operations.

Note 13: Income Taxes

Alkali recorded income tax expense of $6.4 and $7.1 for the three months ending March 31, 2017 and 2016, respectively. The effective tax rate was 40.8% and 41.3% for the three months ending March 31, 2017 and 2016, respectively, and was higher than the statutory rate primarily due to state income taxes and changes in valuation allowance. Each year Alkali files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. These tax returns are subject to examination and possible challenge by the taxing authorities. Positions challenged by the taxing authorities may be settled or appealed by Alkali. As a result, income tax uncertainties are recognized in Alkali’s Interim Condensed Combined Financial Statements in accordance with accounting for income taxes, when applicable.

Note 14: Derivative Instruments

Alkali entered into futures contracts beginning in 2016 in order to mitigate exposure from changes in market prices related to certain natural gas prices. We mitigate our exposures to currency risks and commodity price risks, through a controlled program of risk management that includes the use of derivative financial instruments.

Alkali records these future contracts in either prepaid and other assets or other current liabilities at fair value in the Interim Condensed Combined Balance Sheets and recognizes changes in the fair value of these future contracts in accumulated other comprehensive income, as these instruments have been designated as cash flow hedges.

As of March 31, 2017, we were party to futures contracts with a notional value of $13.0, expiring in December, 2017. For the three months ended March 31, 2017 and 2016, realized gains were immaterial and recorded within the Interim Condensed Combined Statement of Operations. Unrealized (losses)/gains on the future contracts amounted to ($1.5) for the three months ending March 31, 2017 and was recorded in the Interim Condensed Combined Statements of Other Comprehensive Income. We expect to recognize this amount into earnings over the next 12 months.

The fair value of the future contracts as of March 31, 2017 and December 31, 2016 was recorded in Prepaid and other assets and is further summarized below:

Note 15: Commitments and Contingencies

Lease commitments

We lease various types of office space, manufacturing, data processing and rail transportation equipment. The gross rent expense under operating leases amounted to $4.3 and $4.4 for the three months ending March 31, 2017 and 2016, respectively.

At March 31, 2017, minimum rental commitments under non-cancelable operating leases were as follows:

Purchase commitments

The Company is party to coal supply contracts designed to mitigate volatility in the price of coal. The purchase commitments at March 31, 2017 were as follows:

Guarantees

Alkali together with other subsidiaries of the Parent, jointly and severally guarantee the Parent’s debt obligations, namely the UBS revolving credit facility having a maturity date no later than April 1, 2020, the Senior Notes due 2020 and the Senior Notes due 2022. The amount outstanding under these debt obligations was $896 and $584 at March 31, 2017.

Contingencies

We have certain contingent liabilities arising in the ordinary course of business. Some of these contingencies are known but are so preliminary that the merits cannot be determined, or if more advanced, are not deemed material based on current knowledge and some are unknown - for example, claims with respect to which we have no notice or claims which may arise in the future, resulting from products sold, guarantees or warranties made, or indemnities provided. Therefore, we are unable to develop a reasonable estimate of our potential exposure of loss for these contingencies, either individually or in the aggregate, at this time.

Based on information currently available and established reserves, we have no reason to believe that the ultimate resolution of known contingencies will have a material adverse effect on the combined financial position, liquidity or results of operations. However, there can be no assurance that the outcome of these contingencies will be favorable and adverse results in certain of these contingencies could have a material adverse effect on the combined financial position, results of operations in any one reporting period, or liquidity.

Environmental    

Portions of mining operations in the Green River Basin of Wyoming are powered by natural gas which is delivered to the site via pipelines. Condensate from a natural gas pipeline, that is no longer in service, was collected in a condensate tank and “blown- down” into an unlined condensate disposal pit, a practice that was widely accepted at the time. This condensate included contaminant traces of volatile organic compounds (“VOC”) that are characterized and monitored by the indicator parameter, benzene. As a result, site investigations have confirmed that these VOCs are present in the soils and groundwater which extends from the condensate disposal pit to a down-gradient area that is bounded by a groundwater cut-off wall and pump back system. Our Parent received notification from the WyDEQ requiring a Focused Feasibility Study (“FFS”) on the technologies that can be used to remedy the soils and groundwater in contaminated areas. The estimated cost for the FFS of $2.5 and $2.6 was included in other long-term liabilities in the Interim Condensed Combined Balance Sheets at March 31, 2017 and December 31, 2016.

Note 16: Subsequent Events    

The Interim Condensed Combined Financial Statements have been derived from the consolidated financial statements of the Parent, which issued its interim financial statements for the period ended March 31, 2017 on May 4, 2017 and its annual financial statements for the periods ended December 31, 2016 and 2015 on February 24, 2017. Management has evaluated subsequent events through August 2, 2017 and recognized transactions in the Interim Condensed Combined Financial Statements as appropriate. Additionally, management has evaluated transactions that occurred as of the issuance date of these financial statements or August 2, 2017 for the purpose of disclosure of unrecognized events.

On August 2, 2017, the Parent entered into a definitive agreement to sell the Company to Genesis Energy, L.P. Under the terms of the agreement, the Parent will receive $1.325 billion in cash, subject to regulatory approval and customary closing conditions. The sale of the Company is expected to close in the second half of 2017.
