Including the Cristal operations, we now operate titanium-bearing mineral sand mines and beneficiation and smelting operations in North America, Europe,Australia, South Africa and the Asia-Pacific regionBrazil to produce feedstock materials that can be processed into TiO2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and Ultrafine© titanium dioxide used in certain specialty applications. It is our long-term strategic goal to be fully vertically integrated and consume all of our feedstock materials in our own TiO2 pigment facilities in the productionUnited States, Australia, Brazil, UK, France, the Netherlands, China and marketingthe Kingdom of Saudi Arabia (“KSA”). We believe that full vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our coatings and other TiO2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands and titanium dioxide (“TiO2”) pigment. We classify our operations into one reporting segment: TiO2: consistingcreates meaningful quantities of products that are critical components of everyday applications such as paint and other coatings, plastics, paper and other uses and our related mineral sands product streams include titanium feedstock, zircon, and pig iron.

On February 21, 2017, Tronox Limited, The National Titanium Dioxide Company Ltd., a limited company organized under the laws of the Kingdom of Saudi Arabia (“Cristal”), and Cristal Inorganic Chemicals Netherlands Coöperatief W.A., a cooperative organized under the laws of the Netherlands and a wholly owned subsidiary of Cristal (“Seller”), entered into a Transaction Agreement (the “Transaction Agreement”), pursuant to which we agreedalso supply to acquire Cristal’s titanium dioxide business for $1.673 billion in cash, subject to a working capital adjustment at closing (the “Cash Consideration”), plus 37,580,000 Class A ordinary shares (“Class A Shares”), par value $0.01 per share, of Tronox Limited (the “Cristal Transaction”). Followingcustomers around the closing of the Cristal Transaction, the Seller will own approximately 24% of the outstanding ordinary shares (including both Class A and Class B) of Tronox Limited. The Cristal Transaction is conditioned on us obtaining financing sufficient to fund the Cash Consideration, and the Transaction Agreement provides that we must pay to Cristal a termination fee of $100 million if all conditions to closing, other than the financing condition, have been satisfied and the Transaction Agreement is terminated because closing of the Cristal Transaction has not occurred by May 21, 2018. As a result of the refinancing (See Note 11 - Debt), we expect to finance the Cristal Transaction with our cash on hand inclusive of restricted cash and liquidity from our asset-based syndicated revolving credit facility. The Cristal Transaction is also conditioned upon the receipt of various regulatory approvals, including antitrust clearance in numerous jurisdictions. On April 13, 2017, the United States Federal Trade Commission (“FTC”) issued a request for additional information (“Second Request”) to us and Cristal in connection with its filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and Tronox has substantially complied with the Second Request. The Cristal Transaction, which has been unanimously approved by our board of directors (the “Board”), is expected to close by the first quarter of 2018, subject to regulatory approvals and satisfaction of customary closing conditions. On October 2, 2017, at a special meeting of shareholders of the Company held pursuant to the Transaction Agreement, the Company’s shareholders approved a resolution to issue 37,580,000 Class A Shares to the Seller in connection with the acquisition of Cristal’s TiO2 business, and the resulting acquisition of interests in such Class A Shares by the Seller and certain other persons and entities, at the closing of such acquisition.world.

On September 1, 2017, we completed the previously announced sale of our wholly owned subsidiary Tronox Alkali Corporation (“Alkali”) to Genesis Energy, L.P. for proceeds of $1.325 billion in cash, subject to a customary post-closing working capital adjustment (the “Sale”). We have agreed unconditionally to guarantee the indemnification and performance of the obligations of Tronox U.S. Holdings Inc. (“Tronox Holdings”), a subsidiary of Tronox Limited, under the stock purchase agreement (“Purchase Agreement”). Both Tronox Holdings and Genesis Energy, L.P. have agreed, following the closing, to indemnify the other party for losses arising from certain breaches of the Purchase Agreement and for certain other liabilities, subject to certain limitations.

During the three months ended September 30, 2017, we recognized a pre-tax loss of $233 million on the Alkali disposal.  For all periods presented, sales, costs and expenses and income taxes attributable to Alkali together with the loss on disposal have been aggregated in a single caption entitled “Income (loss) from discontinued operations, net of tax” in our Condensed Consolidated Statement of Operations. Included in the calculation of the loss noted above, were approximately $21 million of transaction fees related to the sale of Alkali. For cash flow presentation purposes, these transaction costs are included in “Cash provided by operating activities, continuing operations” on the Condensed Consolidated Statements of Cash Flows. See Note 2 – Discontinued Operations for additional information.

In 2012, our Class B ordinary shares (“Class B Shares”) were issued to Exxaro Resources Limited (“Exxaro”) and one of its subsidiaries in consideration for 74% of Exxaro’s South African mineral sands business. Exxaro has agreed not to acquire any voting shares of Tronox Limited if, following such acquisition, Exxaro will have a voting interest in Tronox Limited of 50% or more unless Exxaro brings any proposal to make such an acquisition to the Board on a confidential basis. In the event an agreement regarding the proposal is not reached, Exxaro is permitted to make a takeover offer for all the shares of Tronox Limited not held by affiliates of Exxaro, subject to certain non-waivable conditions. At September 30, 2017 and December 31, 2016, Exxaro held approximately 43% and 44%, respectively, of the voting securities of Tronox Limited. See Note 18 for additional information regarding Exxaro transactions. On March 8, 2017, Exxaro announced its intention to begin pursuing a path to monetize its ownership stake in Tronox over time. On October 10, 2017, Exxaro sold 22,425,000 Class A ordinary shares in an underwritten registered offering (the “Exxaro Share Transaction”). Subsequent to the Exxaro Shares Transaction, Exxaro held approximately 24% of the Company’s voting securities. Presently, Exxaro intends to sell the remainder of its Tronox shares in a staged process over time pursuant to the existing registration statement, subject to market conditions. Exxaro’s sale of Class A ordinary shares does not impact their 26% ownership interest in each of our Tronox KZN Sands (Pty) Ltd. and Tronox Mineral Sands (Pty) Ltd subsidiaries.

Revision of Previously Issued Consolidated Financial Statements

DuringIn August 2018, the three months ended March 31, 2017, we identified a misstatementFASB issued ASU 2018-13, Fair Value Measurement (“Topic 820”): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard modifies the disclosure requirements in our selling, general, and administrative expense forTopic 820, Fair Value Measurement, by: removing certain prior periodsdisclosure requirements related to a liability resulting from a non-timely filing with a statutory authority. The aggregate misstatement is $11 million, which impacts our previously issued consolidated statements of operations, comprehensive loss, balance sheetsthe fair value hierarchy; modifying existing disclosure requirements related to measurement uncertainty; and cash flowsadding new disclosure requirements, such as ofdisclosing the changes in unrealized gains and losses for the years ended December 31, 2015 and 2016, and the unaudited condensed consolidated financial statementsperiod included in other comprehensive income for the third and fourth quarters and corresponding year-to-date periods of 2015, and each quarter and corresponding year-to-date periods of 2016.

In accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, management evaluated the materiality of the misstatement from qualitative and quantitative perspectives, and concluded that the misstatement was not material to our previously issued annual and interim financial statements. The cumulative amount of the prior period adjustments would have been material to our current statement of operations and comprehensive loss had we made the correction in the three months ended March 31, 2017 and accordingly we will revise our previously issued financial statements to correct this misstatement. We also corrected the timing of other previously recorded immaterial out-of-period adjustments and reflected them in the revised prior period financial statements. The previously recorded immaterial out-of-period adjustments include a $6 million decrease to cost of goods sold due to an overstated depreciation expense and a $7 million increase to cost of goods sold related to royalty tax both originating in 2013 and previously recorded as out-of-period corrections in 2014; a $5 million decrease to cost of goods sold that originated in 2012 and was previously recorded as an out-of-period correction in 2014 due to overstated depletion expense; and other miscellaneous immaterial corrections. Periods not presented herein will be revised, as applicable, in future filings.

Adopted Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which amends ASC Topic 718, Compensation – Stock Compensation. ASU 2016-09 simplifies various aspects related to how share-based payments are accounted for and presented in the financial statements including income taxes and forfeitures of awards. interim periods within those fiscal years beginning after December 15, 2019, with early adoption permitted.We adopted ASU 2016-09 during the first quarter of 2017. Its adoptionthis standard on January 1, 2020 and it did not have a material impact on our unaudited condensedthe Company's consolidated financial statements.

In MarchJune 2016, the FASB issued ASU 2016-05, Derivatives2016-13, Financial Instruments - Credit Losses (Topic 326), as amended. The standard introduces a new accounting model for expected credit losses on financial instruments, including trade receivables, based on estimates of current expected credit losses (CECL). This standard became effective on January 1, 2020, and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships (“ASU 2016-05”), which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument inhad an existing hedging relationship would not, in and of itself, be considered a termination of the derivative instrument or a change in a critical term of the hedging relationship. As long as all other hedge accounting criteria in ASC 815, Derivatives and Hedging (“ASC 815”) are met, a hedging relationship in which the hedging derivative instrument is novated would not be discontinued or require redesignation. This clarification applies to both cash flow and fair value hedging relationships. We adopted ASU 2016-05 during the first quarter of 2017. Its adoption did not have animmaterial impact on our unaudited condensedthe Company's consolidated financial statements.

In July 2015,statements as part of its simplification initiative, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 simplifies the subsequent measurement of inventory by requiring entities to remeasure inventory at the lower of cost and net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We adopted ASU 2015-11 during the first quarter of 2017. The adoption of ASU 2015-11 didour historical bad debt expense has not have an impact on our unaudited condensed consolidated financial statements.been material.

Recently Issued Accounting Pronouncements


We considerDuring the applicability and impact of all recently issued ASUs. Those not listed below were assessed and determined to be either not applicable or expected to have a minimal impact on our consolidated financial statements.

In August 2017,quarter ended March 31, 2020, the FASB issued ASU 2017-12, Derivatives2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform Financial Reporting.” This amendment is elective in nature. Amongst other aspects, this standard provides for practical expedients and Hedging (Topic 815): Targeted Improvementsexceptions to Accounting for Hedging Activities (“ASU 2017-12”),current accounting standards that reference a rate which will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. It is intendedexpected to more closely alignbe dissolved (e.g. London Interbank Offered Rate “LIBOR”) as it relates to hedge accounting, with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. ASU 2017-12 is effective for annual periods beginning on or after December 15, 2018, including interim periods within those periods. Early adoption is permitted which we are considering. We do not expect the adoption of ASU 2017-12 to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under ASU 2017-09, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 is effective prospectively for annual periods beginning on or after December 15, 2017, including interim periods within those periods. Early adoption is permitted. The impact, if any, that ASU 2017-09 will have on our consolidated financial statements will depend on any future award modification.

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 do not expect the adoption of ASU 2017-07 to have a material impact on our consolidated financial statements.
12

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which clarifies the definition of a business with the objective of adding guidance to assist companiescontract modifications and other reporting organizations with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01that reference this rate, subject to meeting certain criteria. The standard is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. Early application of the amendments in ASU 2017-01 is allowed under certain circumstances. The amendments in ASU 2017-01 should be applied prospectively on or after the effective date. The impact, if any, that ASU 2017-01 will have on our consolidated financial statements will depend on the nature of future acquisitions of assets or businesses.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that the reconciliation of the beginning-of-period and end-of period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. ASU 2016-18 does not define restricted cash or restricted cash equivalents, but an entity will need to disclose the nature of the restrictions. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied retrospectively to all periods presented. The adoption of ASU 2016-18 will require us to include and reconcile the amount of “Restricted cash”, together with “Cash and cash equivalents”, for cash flow purposes for all periods presented commencing with the three months ending March 31, 2018.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which reduces the complexity in the accounting standards by allowing the recognition of current and deferred income taxes for an intra-entity asset transfer, other than inventory, when the transfer occurs. Historically, recognition of the income tax consequence was not recognized until the asset was sold to an outside party. This amendment should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. ASU 2016-16 is effective for annual periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods. Early adoption is permitted for all entities as of March 12, 2020 through December 31, 2022.The company is currently evaluating the beginningimpact of the standard.
2. Cristal Acquisition and Related Divestitures
On April 10, 2019, we completed the acquisition of the TiO2 business of Cristal for $1.675 billion of cash, plus 37,580,000 ordinary shares. The total acquisition price, including the value of the ordinary shares at $14 per share on the closing date of the Cristal Transaction, was approximately $2.2 billion. With the acquisition of our shares, an affiliate of Cristal became our largest shareholder. At March 31, 2020, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a wholly-owned subsidiary of National Titanium Dioxide Company Ltd., continues to own 37,580,000 shares of Tronox, or a 26% ownership interest. National Titanium Dioxide Company Ltd. is 79% owned by Tasnee.
In order to obtain regulatory approval for the Cristal Transaction, the FTC required us to divest Cristal's North American TiO2 business, which we sold to INEOS on May 1, 2019, for cash proceeds, net of transaction costs, of $701 million, inclusive of an annual reportingamount for a working capital adjustment.
In conjunction with the Cristal Transaction, we entered into a transition services agreement with Tasnee and certain of its affiliates under which we and the Tasnee entities will provide certain transition services to one another. See Note 20 for further details of the transition services agreement. In conjunction with the divestiture of Cristal's North American TiO2 business to INEOS, we entered into a transition services agreement with INEOS. Under the terms of the transition services agreement, INEOS agreed to provide the following services to Tronox for manufacturing, technology and innovation, information technology, finance, warehousing and human resources. Similarly, Tronox will provide services to INEOS for information technology, finance, product stewardship, warehousing and human resources.
In addition, in order to obtain regulatory approval by the European Commission, we divested the 8120 paper laminate grade, supplied from our Botlek facility in the Netherlands, to Venator Materials PLC (“Venator”). The divestiture was completed on April 26, 2019. Under the terms of the divestiture, we will supply the 8120 grade product to Venator under a supply agreement for an initial term of 2 years, and extendable up to 3 years, to allow for the transfer of the manufacturing of the 8120 grade to Venator. Total cash consideration is 8 million Euros, of which 1 million Euros was paid at the closing and the remaining 7 million Euros (approximately $7.7 million at March 31, 2020 exchange rate) will be paid in equal installments during the second quarters of 2020 and 2021. We recorded a charge of $19 million during the second quarter of 2019, in “Contract loss” in the Consolidated Statements of Operations, reflecting both the proceeds on sale and the estimated losses we expect to incur under the supply agreement with Venator.
We funded the cash portion of the Cristal Transaction through existing cash, borrowings from our Wells Fargo Revolver, and restricted cash which had been borrowed under the Blocked Term Loan and which became available to us for the purpose of consummating the Cristal Transaction.

Allocation of the Purchase Price
For the Cristal Transaction, we have applied the acquisition method of accounting in accordance with ASC 805, "Business Combinations", with respect to the identifiable assets and liabilities of Cristal, which have been measured at estimated fair value as of the date of the business combination.
The aggregate purchase price noted above was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values at the acquisition date, primarily using Level 2 and Level 3 inputs (see Note 14 for an explanation of Level 2 and Level 3 inputs). These fair value estimates represent management’s best estimate of future cash flows (including sales, cost of sales, income taxes, etc.), discount rates, competitive trends, market comparables and other factors. Inputs used were generally determined from historical data supplemented by current and anticipated market conditions and growth rates.
During the three months ended March 31, 2020,  we finalized the purchase price allocation which resulted in increasing environmental liabilities by $8 million, increasing property, plant and equipment by $13 million, decreasing noncontrolling interest by $3 million, decreasing deferred taxes by $6 million, increasing liabilities held for sale by $5 million and decreasing inventory by $4 million, as well as other minor adjustments. The adjustments to the unaudited Condensed Consolidated Statement of Operations that would have been recognized in the second quarter of 2019 if the measurement period adjustments had been completed as of the acquisition date would have increased the net loss by approximately $1 million.
The final purchase price consideration and estimated fair value of Cristal's net assets acquired on April 10, 2019 are shown below. The assets and liabilities of Cristal's North American TiO2 business, that was subsequently divested on May 1, 2019, are shown as held for which financial statements (interim or annual) have not been issued or made available for issuance. sale in the fair value of assets acquired and liabilities assumed.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”) which provides guidance intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years with early adoption permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. We have not yet determined the impact, if any, that ASU 2016-15 will have on our consolidated financial statements as it will depend on the nature of future cash flow transactions impacted by the new guidance.

In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”) which includes a lessee accounting model that recognizes two types of leases - finance leases and operating leases. The standard requires that a lessee recognize on the balance sheet assets and liabilities for leases with lease terms of more than 12 months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will depend on its classification as a finance or an operating lease. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. We have developed an implementation plan for adopting ASU 2016-02, which includes utilizing a software program to manage our lease obligations. We are evaluating the impact that ASU 2016-02 will have on our consolidated financial statements and have concluded that we will not early adopt ASU 2016-02. Refer to Note 14 and 17 included in ourCompany’s Annual Report on Form 10-K for the year ended December 31, 2016 regarding current obligations under lease agreements.2019.
3. Restructuring Initiatives
In April 2019, we announced the completion of the Cristal Transaction. During the second quarter of 2019, as a result of the acquisition, we outlined a broad based synergy savings program that is expected to reduce costs, simplify processes and focus the organization’s structure and resources on key growth initiatives. During the three months ended March 31, 2020, we recorded costs of $2 million in our unaudited Condensed Consolidated Statement of Operations of which there were 0 comparable amounts in the three months ended March 31, 2019. The costs consisted primarily of charges for employee related costs, including severance.

For most transactions this occurs when products are shipped from our manufacturing facilities or at a later point when control of the products transfers to depict the transfer of promised goodscustomer at a specified destination or servicestime.
Contract assets represent our rights to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires several new disclosures.

Subsequentsituations other than the passage of time. For products that we have transferred to our customers, our rights to the issuanceconsideration are typically unconditional and only the passage of time is required before payments become due. These unconditional rights are recorded as accounts receivable. As of March 31, 2020, and December 31, 2019, we did not have material contract asset balances.
Contract liabilities represent our obligations to transfer products to a customer for which we have received consideration from the customer. Infrequently we may receive advance payment from our customers that is accounted for as deferred revenue. Deferred revenue is earned when control of the May 2014 guidance, several clarificationsproduct transfers to the customer, which is typically within a short period of time from when we received the advanced payment. Contract liability balances as of March 31, 2020 and updates have been issued on this topic, the most recent of which was issued in May 2017. We are executing our implementation plan for adopting ASU 2014-09December 31, 2019 were approximately $3 million and are currently operating in line with that plan. We have completed phase 1 of our contract evaluation process and are continuing to review additional contracts while currently validating the results of applying the new revenue guidance. We have also started documenting our accounting policies and evaluating the new disclosure requirements and we expect to complete the evaluation of the impact of the accounting and disclosure requirements on our business processes, controls and systems$1 million, respectively. Contract liability balances were reported as “Accounts payable” in the fourth quarter of 2017. We are evaluating the impact that ASU 2014-09 will have on our consolidated financial statements and will adopt the new standard using the modified retrospective approach effective January 1, 2018.

2.Discontinued Operations

Concurrent with the announcement of the Cristal Transaction, we expressed intent to begin a process to market our Alkali soda ash business which met the criteria as held for sale in the third quarter and was sold on September 1, 2017. The sale of Alkali is an important step in positioning us as a global leader in the titanium dioxide (TiO2) industry. The proceeds will be used to fund a portion of the cash consideration for the Cristal acquisition and a portion was also used in the refinancing of our debt. See Notes 1 and 11. The criteria for presentation of Alkali as a discontinued operation in accordance with Accounting Standards Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity was met in the third quarter of 2017.  This disposal is considered a strategic shift that has and will have a major effect on the Company’s operations and financial results; therefore, the results of Alkali have been classified as discontinued operations for all periods presented.  Alkali assetsunaudited Condensed Consolidated Balance Sheets.  All contract liabilities as of December 31, 2016 have been segregated from continuing operations and presented2019 were recognized as current assets or current liabilities from discontinued operations.revenue in “Net sales” in the unaudited Condensed Consolidated Statements of Operations during the first quarter of 2020.

Disaggregation of Revenue
Alkali, which was previously one of our two operating and reportable segments, included certain allocated corporate costs which have been reallocated to Corporate. The amount of allocated corporate costs was $1 million and $3 million, respectively, for each of the three and nine months ended September 30, 2017 and 2016.  After the sale, we nowWe operate in a singleunder 1 operating and reportable segment, TiO2. We disaggregate our revenue from contracts with customers by product type and geographic area. We believe this level of disaggregation appropriately depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors and reflects how our business is managed.

Net sales to external customers by geographic areas where our customers are located were as follows:

Tronox Holdings plc, a U.K. public limited company, became the fourth quarter of 2016, we implemented various steps of an internal corporate restructuring plan to simplify our corporate, finance and legal structure and thereby improve operational, administrative, and commercial synergies (the “Corporate Reorganization”). As a result of this Corporate Reorganization, we reduced our cross jurisdictional financing arrangements during 2016; therefore, the three and nine months period ended September 30, 2017 is not impacted by withholding tax accruals on interest income. In connection with the Corporate Reorganizationpublic parent during the three months period ended March 31, 2017,2019. During the three months ended March 31, 2019, Tronox Limited became managed and controlled in the United Kingdom (“U.K”), with no additional impacts to the consolidated provision for income taxes due to the valuation allowances in various jurisdictions.

During 2016, Tronox Limited was managed and controlled in Australia which has a statutory tax rate of 30%.

During the three months ended September 30, 2017 we sold the Alkali segment of our operations.  The Alkali results are now shown as discontinued operations and are not included in the tabular results above.  The effective tax raterates for the three months ended September 30, 2017 differs from bothMarch 31, 2020 and 2019 are influenced by a variety of factors, primarily income and losses in jurisdictions with full valuation allowances, disallowable expenditures, restructuring impacts, and our jurisdictional mix of income at tax rates different than the three months ended September 30, 2016,U.K. statutory rate.
Upon completion of the Cristal Transaction, we now have additional jurisdictions with operational income.  The statutory tax rates on income earned in Australia (30%), the United States (21%), South Africa (28%), France (28.92%), China (25%), Brazil (34%), the Kingdom of Saudi Arabia (KSA) (20%), and the nine months ended September 30, 2017 primarily due to the discrete results of reporting the effects of this sale.

Tax rates will be reduced in foreign jurisdictions taxed at rates different than 19%. The effective tax rate for the three and nine months ended September 30, 2016 differs from the Australian statutory rate of 30% primarily due to valuation allowances and income in foreign jurisdictions taxed at rates lower than 30%, and withholding tax accruals on interest income. The income tax provision for the three and nine months ended September 30, 2017 differs from the income tax provision for the three and nine months ended September 30, 2016 due to withholding tax accruals on interest income which we made during 2016.

The statutory tax rates in various countries where subsidiaries of Tronox Limited have operations are different than both the U.K.France and the Australian tax rates.

We continue to maintain full valuation allowances related to the total net deferred tax assets in Australia the Netherlands, and the U.S., as we cannot objectively assert that these deferred tax assets are more likely than not to be realized. FutureIt is reasonably possible that a portion of these valuation allowances could be reversed within the next year due to increased profitability levels. For entities acquired in the Cristal Transaction, we have full valuation allowances in Australia, Belgium, Brazil, Switzerland and the U.S. Until these valuation allowances are eliminated, future provisions for income taxes for these jurisdictions will include no tax benefits with respect to losses incurred and tax expense only to the extent of current state tax payments until the valuation allowances are eliminated.payments. Additionally, we have valuation allowances against specific tax assets in the Netherlands, South Africa, and during the nine month period ended September 30, 2017 we established a valuation allowance of $7 million against deferred tax assetsU.K.

Debt Refinancing

On September 22, 2017, we completed our offering of our Senior Notes due 2025 for an aggregate principal amount of $450 million, the net proceeds of which, together with borrowings under our $2.150 billion New Term Loan Facility and proceeds from the Alkali sale, funded the redemption of the remaining outstanding balance of our Senior Notes due 2020 and repayment in full of the remaining outstanding balance of our $1.5 billion Prior Term Loan. In addition, we paid off our UBS Revolver and entered into a new asset-based revolving syndicated facility with Wells Fargo (all defined below).

The refinancing of our Senior Notes due 2020 was considered a debt extinguishment in accordance with ASC 470, Debt (“ASC 470”).  However, for refinancing of both the UBS Revolver and the New Term Loan Facility, a portion of each of these refinancing arrangements were considered modifications and a portion considered extinguishments in accordance with the requirements of ASC 470 as some of the original lenders in the original syndications were part of the new lender base.

Short-term12. Debt

During the third quarter of 2017, we repaid the $150 million outstanding balance under the global senior secured asset-based syndicated revolving credit facility with UBS AG (the “UBS Revolver”). Concurrent with entering into the Wells Fargo Revolver, described below, the UBS Revolver was terminated. Unamortized original debt issuance costs of $1 million relating to the UBS Revolver were included in “Gain (loss) on extinguishment of debt” in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017. The remaining unamortized balance of original debt issuance costs of $2 million relating to the UBS Revolver will be amortized over the life of the Wells Fargo Revolver.

Wells Fargo Revolver

On September 22, 2017, we entered into a new global senior secured asset-based syndicated revolving credit facility with the lenders party thereto and Wells Fargo Bank, N.A. as administrative agent (the “Wells Fargo Revolver”). The Wells Fargo Revolver provides us with up to $550 million of revolving credit loans, with an $85 million sublimit for letters of credit, and has a maturity date of September 22, 2022.  Our availability of revolving credit loans and letters of credit is subject to a borrowing base. Borrowings bear interest at our option, at either an adjusted London Interbank Offered Rate (“LIBOR”) plus an applicable margin that ranges from 1.25% to 1.75%, or a base rate, which is defined to mean the greatest of (a) the administrative agent’s prime rate, (b) the Federal funds effective rate plus 0.50% and (c) the adjusted LIBOR for a one-month period plus 1.00%, plus an applicable margin that ranges from 0.25% to 0.75%, in each case, based on the average daily borrowing availability. At September 30, 2017, there was no outstanding revolving credit loans under the Wells Fargo Revolver, except for $19 million of issued and undrawn letters of credit under the Wells Fargo Revolver. Long-Term Debt issuance costs associated with the Wells Fargo Revolver of $6 million ($2 million remaining from the UBS Revolver and $4 million incurred for the Wells Fargo Revolver) were included in “Other long-term assets” in the Condensed Consolidated Balance Sheets at September 30, 2017 and will be amortized over the life of the Wells Fargo Revolver.

Prior Term Loan

On April 23, 2014,the borrowing base in order to increase the potential availability of credit.  We also voluntarily reduced the revolving credit lines under the Wells Fargo Revolver from $550 million to $350 million. As a result of this modification, we along with our wholly owned subsidiary, Tronox Pigments (Netherlands) B.V., and certain named guarantor subsidiaries, entered intoaccelerated the recognition of a Third Amended and Restated Credit and Guaranty Agreement (the “Third Agreement”) withportion of the lenders party thereto and Goldman Sachs Bank USA, as administrative agent. Pursuantdeferred financing costs related to the Third Agreement, we obtainedWells Fargo Revolver and during the three months ended March 31, 2019, recorded a $1.5 billion senior secured term loan (the “Prior Term Loan”) with a maturity datecharge of March 19, 2020. As mentioned above, on September 22, 2017, we repaid the remaining $1.4 billion outstanding balance of the $1.5 billion Prior Term Loan and entered into the New Term Loan Facility described below. Unamortized original debt discount and issuance costs of $1$2 million relating to the Prior Term Loan were included in “Gain (loss)“Loss on extinguishment of debt” in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017. The remaining balance of unamortized original debt discount and issuance costs of $16 million relating to the Prior Term Loan will continue to be amortized over the life of the New Term Loan Facility.

New Term Loan Facility

On September 22, 2017, we entered into a new senior secured first lien term loan facility (the “New Term Loan Facility”) with the lenders party thereto and Bank of America, N.A., as administrative agent, with a maturity date of September 22, 2024. The New Term Loan Facility consists of (i) a U.S. dollar term facility in an aggregate principal amount of $1.5 billion (the “New Term Loans”) with our subsidiary, Tronox Finance LLC (“Tronox Finance”) as the borrower and (ii) a U.S. dollar term facility in an aggregate principal amount of $650 million (the “Blocked Term Loan”)  with our unrestricted subsidiary, Tronox Blocked Borrower LLC (the “Blocked Borrower”) as the borrower, which Blocked Term Loan was funded into a blocked account.  Upon consummation of the Cristal acquisition, the Blocked Borrower will merge with and into Tronox Finance, and the Blocked Term Loan will become available to Tronox Finance. If the Cristal Acquisition is terminated, the Blocked Term Loan will be repaid to the lenders of such Blocked Term Loan. The proceeds from the Blocked Term Loan were included in “Restricted cash” in the Condensed Consolidated Balance Sheets at September 30, 2017. The term loans under the New Term Loan Facility bear interest at the “Applicable Rate” defined by reference to a grid pricing matrix that relates to our first lien net leverage ratio. Based upon our first lien net leverage ratio, the Applicable Rate under the New Term Loan Facility as of September 30, 2017 was 300 basis points plus LIBOR. The New Term Loan Facility was issued net of an original issue discount of $11 million. Debt issuance costs of $4 million relating to the New Term Loans were included in “Gain (loss) on extinguishment of debt” in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017. Debt issuance costs of $30 million associated with the New Term Loan Facility ($13 million remaining from the Prior Term Loan and $17 million incurred for the New Term Loan Facility) were recorded as a direct reduction of the carrying value of the long-term debt as described below and will be amortized over the life of the New Term Loan Facility.

Senior Notes due 2020

On September 25, 2017, we redeemed (the “Redemption”) the $896 million outstanding balance of our $900 million aggregate principal, 6.375% senior notes due 2020 issued by Tronox Finance (the “Senior Notes due 2020”). The total cash payment made in connection with the Redemption was approximately $917 million, and included accrued interest of $7 million and a call premium of $14 million (the “Call Premium”) included in “Gain (loss) on extinguishment of debt” inwithin the unaudited Condensed Consolidated StatementsStatement of Operations.

Senior Notes due 2022

We have $600 million aggregate principal amount, 7.50% Senior Notes due 2022 (the “Senior Notes due 2022”) which notes were issued pursuant to an indenture dated March 19, 2015 (the “2022 Indenture”).

Additionally, during the three months ended March 31, 2020, our KSA subsidiary drew down $13 million on its SABB Credit Facility for local working capital purposes. At March 31, 2020, the short-term debt balance was $212 million based on the March 31, 2020 exchange rate. There were no comparable amounts outstanding as of December 31, 2019.
Debt Covenants
At March 31, 2020, we are in compliance with all financial covenants in our debt facilities.
New Debt
On May 1, 2020, Tronox Incorporated, a wholly-owned indirect subsidiary of the 2022 Indenture, among other things, limit, in certain circumstances, the ability of us to: incur certain additional indebtedness and issue preferred stock; make certain dividends, distributions, investments and other restricted payments; sell certain assets; incur liens; agree to any restrictions on the ability of certain subsidiaries to make payments to us; consolidate or merge with or into, or sell substantially all of our assets to, another person; enter into transactions with affiliates; and enter into new lines of business. At September 30, 2017 and December 31, 2016, debt issuance costs related to the Senior Notes due 2022 of $8 million and $10 million, respectively, were recorded as a direct reduction of the carrying value of the long-term debt as described below.

At December 31, 2019, current assets of $34 million were recorded in prepaid and other current assets and long-term assets of $3 million are recorded in other long-term assets.
Interest Rate Risk
During the second quarter of 2019, we entered into interest-rate swap agreements with an aggregate notional value of $750 million, representing a portion of our Term Loan Facility, which effectively converts the variable rate to a fixed rate for that portion of the loan. The agreements expire in September 22, 2017 (the “2025 Indenture”).2024. The Company’s objectives in using the interest-rate swap agreements are to add stability to interest expense and to manage its exposure to interest rate movements. These interest rate swaps have been designated as cash flow hedges and involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.
Fair value gains or losses on these cash flow hedges are recorded in other comprehensive (loss) income and are subsequently reclassified into interest expense in the same periods during which the hedged transactions affect earnings. At March 31, 2020 and December 31, 2019, the net unrealized loss of $54 million and $22 million, respectively, was recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet. For the three months ended March 31, 2020, the amounts recorded in interest expense related to the interest-rate swap agreements were not material.
Foreign Currency Risk
During the third quarter of 2019 and the first quarter of 2020, we entered into foreign currency contracts used to hedge forecasted third party non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold for our Australian subsidiaries. These foreign currency contracts are designated as cash flow hedges. Changes to the fair value of these foreign currency contracts are recorded as a component of other comprehensive (loss) income, if these contracts remain highly effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or are recognized in other income (expense) when the transactions are no longer probable of occurring.
As of March 31, 2020, we had notional amounts of (i) 2.9 billion South African rand (or approximately $163 million at March 31, 2020 exchange rate) that expire between April 29, 2020 and February 25, 2021 to reduce the exposure of our South African subsidiaries’ third party sales to fluctuations in currency rates, and (ii) $691 million Australian dollars (or approximately $422 million at March 31, 2020 exchange rate) that expire between April 29, 2020 and December 30, 2021 to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates. For the three months ended March 31, 2020, we recorded a loss of $1 million and a loss of $4 million in “Net sales” and "Cost of goods sold", respectively, on the unaudited Condensed Consolidated Statement of Operations, related to our cash flow hedges. There were

Table of Contents
0 amounts recognized for foreign currency cash flow hedges in the comparative period of 2019. At March 31, 2020 and December 31, 2019, there was an unrealized net loss of $30 million and an unrealized net gain of $30 million, respectively, recorded in "Accumulated other comprehensive loss" on the unaudited Condensed Consolidated Balance Sheet, of which $25 million is expected to be recognized in earnings over the next twelve months.
We enter into foreign currency contracts for the South African rand and Australian dollar to reduce exposure of our subsidiaries’ balance sheet accounts not denominated in our subsidiaries’ functional currency to fluctuations in foreign currency exchange rates. We use a combination of zero-cost collars or forward contracts to reduce the exposure.  For accounting purposes, these foreign currency contracts are not considered hedges. The change in fair value associated with these contracts is recorded in “Other expense, net” within the unaudited Condensed Consolidated Statement of Operations and partially offsets the change in value of third party and intercompany-related receivables not denominated in the functional currency of the subsidiary. At March 31, 2020, there was (i) 638 million South African rand (or approximately $36 million at March 31, 2020 exchange rate) and (ii) $82 million Australian dollars (or approximately $50 million at March 31, 2020) of notional amount outstanding foreign currency contracts with a fair value of a loss of $10 million. At December 31, 2019, there was (i) 712 million South African rand (or approximately $40 million at March 31, 2020 exchange rate) and (ii) $89 million Australian dollars (or approximately $54 million at March 31, 2020 exchange rate) of notional amounts outstanding foreign currency contracts with a fair value of a gain of less than $1 million.  For the three months ended March 31, 2020 and 2019, we have recorded losses of $16 million and gains of $5 million, respectively, related to foreign currency contracts in our unaudited Condensed Consolidated Statement of Operations.
14. Fair Value
Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standards also have established a fair value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value into three broad levels as follows:
Level 1 -Quoted prices in active markets for identical assets or liabilities
Level 2 -Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly
Level 3 -Unobservable inputs based on the Company’s own assumptions
Our debt is recorded at historical amounts. The following table presents the fair value of our debt and derivative contracts at both March 31, 2020 and December 31, 2019:

We determined the fair value of the Term Loan Facility, the Senior Notes due 2025 Indenture and the Senior Notes due 2025 provide,2026 using quoted market prices, which under the fair value hierarchy is a Level 1 input. We determined the fair value of the Standard Bank Term Loan Facility and Tikon Loan utilizing transactions in the listed markets for identical or similar liabilities, which under the fair value hierarchy is a Level 2 input. The fair value of the Australian Government Loan is based on the contracted amount which is a Level 2 input.

We determined the fair value of the foreign currency contracts and the interest rate swaps using inputs other than quoted prices in active markets that are observable either directly or indirectly. The fair value hierarchy for the foreign currency contracts and interest rate swaps is a Level 2 input.
The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and short-term debt approximate fair value due to the short-term nature of these items.

Purchase and Capital Commitments — Includes obligations for purchase requirements of process chemicals, supplies, utilities and services entered into in the ordinary course of business. At March 31, 2020, purchase commitments were $166 million for 2020, $77 million for 2021, $55 million for 2022, $41 million for 2023, $36 million for 2024, and $76 million thereafter.
Letters of Credit—At March 31, 2020, we had outstanding letters of credit and bank guarantees of $71 million, of which $34 million were letters of credit and $37 million were bank guarantees. Amounts for performance bonds were not material.
Environmental Matters— It is our policy to record appropriate liabilities for environmental matters when remedial efforts are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flows. The timing of cash expenditures depends principally on the timing of remedial investigations and feasibility studies, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties.  Included in these environmental matters are the following:

Hawkins Point Plant. Residual waste mud, known as Batch Attack Mud, and a spent sulfuric waste stream were deposited in an onsite repository (the “Batch Attack Lagoon”) at a former TiO2 manufacturing site, Hawkins Point Plant in Baltimore, Maryland, operated by Cristal USA, Inc. from 1954 until 2011.  We assumed responsibility for remediation of the Hawkins Point Plant when we acquired the TiO2 business of Cristal in April 2019.  In 1984, a predecessor of Cristal and the Maryland Department of the Environment (“MDE”) entered into a consent decree (the “Consent Decree”) to address the Batch Attack Lagoon.  The Consent Decree required that Cristal close the Batch Attack Lagoon when the Hawkins Point Plant ceased operations.  In addition, we are investigating whether hazardous substances are migrating from the Batch Attack Lagoon.   A provision of $61 million has been made in our financial statements for the Hawkins Point Plant consistent with the accounting policy described above. We are in discussions with the MDE regarding a new consent decree to address both the Batch Attack Lagoon as well as other environmental contamination issues associated with the Hawkins Point Plant.
Other Matters— We are subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of our business, including matters relating to commercial transactions, prior acquisitions and divestitures, including our acquisition of Cristal, employee benefit plans, intellectual property, and environmental, health and safety matters. We recognize a liability for any contingency that is probable of occurrence and reasonably estimable. We continually assess the likelihood of adverse judgments of outcomes in these matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Included in these other matters is the following:
Venator Materials plc v. Tronox Limited. In May 2019, Venator Materials plc (“Venator”) filed an action in the Superior Court of the State of Delaware alleging among other things that we owed Venator a $75 million “Break Fee” pursuant to the Senior Notes due 2025 are senior unsecured obligationsterms of a preliminary agreement dated July 14, 2018 (the “Exclusivity Agreement”). The Exclusivity Agreement required, among other things, Tronox Financeand Venator to use their respective best efforts to negotiate a definitive agreement to sell the entirety of the National Titanium Dioxide Company Limited’s (“Cristal’s”) North American operations to Venator if a divestiture of all or a substantial part of these operations were required to secure the approval of the Federal Trade Commission for us to complete our acquisition of Cristal’s TiO2 business. In June 2019, we denied Ventaor's claims and counterclaimed against Venator seeking to recover $400 million in damages from Venator that we suffered as a result of Venator’s breaches of the Exclusivity Agreement. Specifically, we alleged, among other things, that Venator’s failure to use best efforts constituted a material breach of the Exclusivity Agreement and directly resulted in and caused us to sell Cristal’s North American operations to an alternative buyer for $701 million, $400 million less than the price Venator had agreed to in the Exclusivity Agreement. Though we believe that our interpretation of the Exclusivity Agreement is correct, there can be no assurance that we will prevail in litigation.

20. Related Parties
Exxaro
On November 26, 2018, we, certain of our subsidiaries to: incur secured indebtedness, engageand Exxaro entered into the Completion Agreement. The Completion Agreement provides for the orderly sale of Exxaro’s remaining ownership interest in us, subject to market conditions, helped to facilitate the Re-domicile Transaction, as well as addressed several legacy issues related to our 2012 acquisition of Exxaro’s mineral sands business. Pursuant to the terms of the Completion Agreement, Tronox has covenanted to pay Exxaro an amount equal to any South African capital gains tax assessed on Exxaro in respect of any profit arising to it on a disposal of any of its ordinary shares subsequent to the Re-domicile Transaction where such tax would not have been assessed but for the Re-domicile Transaction.  Similarly, Exxaro has covenanted to pay Tronox an amount equal to any South African tax savings Exxaro may realize in certain sale-leaseback transactionssituations from any tax relief that would not have arisen but for the Re-domicile Transaction.
Pursuant to the terms of the Completion Agreement, on May 9, 2019, Exxaro exercised their right under the agreement to sell 14 million shares to us for an aggregate purchase price of approximately $200 million or $14.319 per share, plus fees of approximately $1 million.The share price was based upon a 5% discount to the 10 day volume weighted average price as of the day that Exxaro exercised their sale notice to us. Upon repurchase of the shares by the Company, the shares were cancelled. As a result of the sale of the $14 million shares on May 9, 2019, we recorded a liability of approximately $4 million which was included in “Accrued liabilities” in our Consolidated Balance Sheets as of December 31, 2019 and merge, consolidatewas subsequently paid in January 2020.
Futhermore, pursuant to the Completion Agreement, the parties agreed to accelerate our purchase of Exxaro's 26% membership interest in Tronox Sands LLP, a U.K. limited liability partnership ("Tronox Sands"). On February 15, 2019, we completed the redemption of Exxaro's ownership interest in Tronox Sands for consideration of approximately ZAR 2.06 billion (or approximately $148 million in cash), which represented Exxaro's indirect share of the loan accounts in our South African subsidiaries.
At March 31, 2020, Exxaro continues to own approximately 14.7 million shares of Tronox, or a 10.3% ownership interest, as well as their 26% ownership interest in our South African operating subsidiaries.
At the present time, we are unable to reasonably determine when and if Exxaro will sell substantiallyits remaining shares in the foreseeable future, and as a result, we are not able to estimate what the capital gains tax impacts would be should Exxaro sell its remaining shares.

Tasnee/Cristal
On April 10, 2019, we announced the completion of the acquisition of the TiO2 business of Cristal for $1.675 billion of cash, subject to a working capital and noncurrent liability adjustment, plus 37,580,000 ordinary shares. At March 31, 2020, Cristal International Holdings B.V. (formerly known as Cristal Inorganic Chemical Netherlands Cooperatief W.A.), a wholly-owned subsidiary of Tasnee, continues to own 37,580,000 shares of Tronox, or a 26% ownership interest. In February 2020, Tronox and Cristal resolved the working capital and noncurrent liability adjustment by agreeing that no payment was required by either party.
On May 9, 2018, we entered into an Option Agreement with AMIC which is owned equally by Tasnee and Cristal. Under the terms of the Option Agreement, AMIC granted us an option (the “Option”) to acquire 90% of a special purpose vehicle (the “SPV”), to which AMIC’s ownership in a titanium slag smelter facility (the “Slagger”) in The Jazan City for Primary and Downstream Industries in KSA will be contributed together with $322 million of AMIC indebtedness (the “AMIC Debt”). As of March 31, 2020, we have loaned $89 million for capital expenditures and operational expenses to facilitate the start-up of the Slagger and we have recorded this loan payment and related interest of $4 million within “Other long-term assets” on the unaudited Condensed Consolidated Balance Sheet at March 31, 2020. The Option did not have a significant impact on the financial statements as of or for the periods ended March 31, 2020.
Prior to the Cristal acquisition, the Company also acquired feedstock from AMIC for consumption in production. There were no purchases of feedstock for the three months ended March 31, 2020. In addition, from time to time, Tronox sells Titanium Tetrachloride (TiCl4) to AMIC for use at a sponge plant facility. During the three months ended March 31, 2020, Tronox recorded $6 million for TiCl4 product sales made to AMIC and such amounts were recorded in “Net sales” on the unaudited Condensed Consolidated Statement of Operations. At March 31, 2020, Tronox had a receivable from AMIC of $2 million from the sale of TiCl4 that is recorded within “Prepaid and other assets”on the unaudited Condensed Consolidated Balance Sheet.
In conjunction with the acquisition on April 10, 2019 we entered into a transition services agreement with Tasnee, Cristal and AMIC. Under the terms of the transition services agreement, Tasnee and its affiliates will provide services to Tronox related to information technology support and infrastructure, logistics, safety, health and environmental, treasury and tax. Similarly, Tronox will provide services to Tasnee and its affiliates for information technology support and infrastructure, finance and accounting, tax, treasury, human resources, logistics, research and development and business development.
As part of the transition services agreement, Tronox recorded a net reduction of approximately $1 million in “Selling, general and administrative expenses” for the three months ended March 31, 2020 in the unaudited Condensed Consolidated Statement of Operations. The net reduction of selling, general and administrative expenses associated with the transition services agreement generally represents a recovery of the related costs. At March 31, 2020, Tronox had a receivable due from Tasnee of $15 million and a payable due to Tasnee of $4 million that are recorded within “Prepaid and other assets” and “Accrued liabilities”, respectively, on the unaudited Condensed Consolidated Balance Sheet. The balance in prepaid and other assets and remaining balances in accrued liabilities primarily relate to pre-acquisition activity and those balances are expected to be settled in the near term.
On December 29, 2019, we entered into an agreement, subject to regulatory approval, with Cristal to acquire certain assets co-located at our Yanbu facility that had been not included in the Cristal Transaction and which assets produce metal grade TiCl4 for a $36 million note payable. Under such agreement, the metal grade TiCl4 will be purchased by Advanced Metal Industries Cluster and Toho Titanium Metal Co. Ltd (ATTM), a joint venture between AMIC and Toho Titanium Company Ltd. ATTM uses the TiCl4, which we supply by pipeline, for the production of titanium sponge. We expect this transaction to close in 2020. During the three months ended March 31, 2020, Tronox recorded $1 million for purchase of chlorine gas from ATTM and such amounts are recorded in "Cost of goods sold" on the unaudited Condensed Consolidated Statement of Operations. The amount due to ATTM as of March 31, 2020 for the purchase of chlorine gas was less than $1 million and is recorded within “Accounts payable”on the unaudited Condensed Consolidated Balance Sheet.

Overview
Tronox Holdings plc (referred to herein as “Tronox,” “we,” “us,” or “our”) is a public limited company registered under the laws of England and Wales. As a result of the Re-domicile Transaction, Tronox Limited became a wholly-owned subsidiary of Tronox Holdings plc. On April 10, 2019, we completed the acquisition from National Industrialization Company ("Tasnee") of the TiO2 business of The National Titanium Dioxide Company Ltd. (“Cristal”) (the “Cristal Transaction”). In order to obtain regulatory approval for the Cristal Transaction, we were required to divest Cristal's North American TiO2 business, which was sold in May 2019. See Note 2 for further details on the Cristal Transaction.
Including the Cristal operations, we now operate titanium-bearing mineral sand mines and beneficiation and smelting operations in Australia, South Africa and Brazil to produce feedstock materials that can be processed into TiO2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and Ultrafine© titanium dioxide used in certain specialty applications. It is our long-term strategic goal to be fully vertically integrated and consume all of our assets.feedstock materials in our own TiO2 pigment facilities in the United States, Australia, Brazil, UK, France, the Netherlands, China and the Kingdom of Saudi Arabia (“KSA”). We believe that full vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our coatings and other TiO2 customers throughout the world. The termsmining, beneficiation and smelting of titanium bearing mineral sands creates meaningful quantities of zircon, which we also supply to customers around the 2025 Indenture also include certain limitations onworld.
Tronox Synergy Savings Program
On April 10, 2019, we completed the Cristal Transaction. During the second quarter of 2019 as part of our non-guarantor subsidiaries incurring indebtedness. Debt issuance costsstrategy for realizing value from the acquisition, we announced our goal of $9achieving approximately $220 million relatingin operating synergies by 2022. These synergies are expected to be realized from the Senior Notes due 2025 were recorded asfollowing areas:
operational enhancements through, among other things, technology exchange, optimization of feedstock cost at pigment plants and performance improvements at the Yanbu plant in Saudi Arabia;
feedstock initiatives including, among other things, maximizing synthetic rutile and slag output and better utilizing our diverse types of feedstock in our TiO2 plants and other initiatives that more efficiently integrate our global feesdtock chain;
supply chain savings from, among other things, volume purchasing discounts for a direct reductionrange of raw materials and services, including shipping and freight, and rationalizing the carrying valueproduction of the long-term debt as described below and will be amortized over the lifeour broad portfolio of the Senior Notes due 2025.

reductions in selling, general and administrative expenses primarily from employee-related costs and indirect spend consolidation.
In connection with realizing the synergies discussed above, during the year ended December 31, 2019 and including the three months ended March 31, 2020, we incurred restructuring costs of $24 million for employee related costs, including severance. See Note 3 of notes to unaudited condensed consolidated financial statements for further information on restructuring.
During the first quarter of 2020, we have delivered total synergies of $45 million, of which $38 million have been reflected in our EBITDA in the first quarter of 2020 and $7 million are cash and other synergies not reflected in EBITDA. Our synergy targets continue to be $190 million for 2020, $275 million for 2021 and $325 million for 2022.
Business Environment
The following discussion includes trends and factors that may affect future operating results:
During the current coronavirus pandemic, our operations have been designated as essential to support the continued manufacturing of products such as food and medical packaging, medical equipment, pharmaceuticals, and personal protective gear. As of the end of the quarter, all of our sites were running to planned production levels, excluding South Africa where we elected to shutdown the mining of ilmenite for a period of time near the end of the first quarter of 2020 and into a portion of the second quarter of 2020. During that time, we utilized our existing inventories of ilmenite to operate our smelters which operated at near-full rates to produce chloride slag with a reduced workforce through the 21-day countrywide lockdown period. On April 13, 2020, our South African mines and concentrators were back up and running at full capacity.
Our first quarter revenue increased 4% sequentially driven primarily by higher TiO2 volumes.  Average TiO2 selling prices remained stable, while Zircon average selling prices were 8% lower. The Covid-19 pandemic has impacted, and will continue to impact, our industry and business. Demand for TiO2 in North America has been the most resilient, as we benefit from our exposure to do-it-yourself coatings and packaging applications. Regions hit hardest by the virus have experienced lower than normal demand, including southern Europe, Brazil and India. Zircon demand remains mixed, with recovering volumes in China offset by weaker demand in southern Europe and India. Zircon volumes for the first quarter were in-line with fourth quarter 2019 volumes. Based upon the status of social restrictions, the announced plans for the re-opening of economies around the world, and our conversations with and public statements by our customers, we anticipate declines in second quarter TiO2 volumes versus first quarter 2020, while we expect Zircon volumes for the second quarter to remain largely in line with the first quarter.

Gross margin improved sequentially from the fourth quarter 2019 to the first quarter 2020 due to the favorable impacts of volume and mix, reductions in production costs and favorable impacts of foreign currency on costs. These impacts were partially offset by the negative impacts of average selling prices.
As of March 31, 2020, our total available liquidity was $570 million, including $420 million in cash and cash equivalents and $150 million available under revolving credit agreements including $123 million available under our Asset Backed Lending ("ABL") facility. Our total debt was $3.2 billion and net debt to trailing-twelve month Adjusted EBITDA pro forma for the Cristal transaction was 3.9x. There are no upcoming maturities on the Company’s term loan or bonds until 2024. The Company also has no financial covenants on its term loan or bonds and only one springing financial covenant on its ABL facility, which we do not expect to be triggered based on our current scenario planning.
On May 1, 2020, Tronox Incorporated, a wholly-owned indirect subsidiary of the Company, issued 6.5% senior secured notes due 2025 for an aggregate principal amount of $500 million (the "6.5%Senior Secured Notes due 2025"). A portion of the proceeds of this debt offering was utilized to repay the $200 million of the Company's outstanding borrowings under its Wells Fargo, Standard Bank, and Emirates revolvers.
Pro Forma Income Statement Information
The acquisition of the TiO2 business of Cristal on April 10, 2019 impacts the comparability of the reported results for 2020 compared to 2019. Since Tronox and Cristal have combined their respective businesses effective with the merger date of April 10, 2019, the three months ended March 31, 2020 reflect the results of the combined business, while the three months ended March 31, 2019 includes only the results of the legacy Tronox business. To assist with a discussion of the 2020 and

On a reported basis, net sales of $722 million for the three months ended March 31, 2020 increased by 85% compared to $390 million for the same period in 2019. The three months ended March 31, 2020 includes $326 million, or 45% revenue growth related to the acquired operations of Cristal. Incremental to the Cristal acquistion, increases in TiO2 sales volumes and higher CP slag volumes partially offset by lower Zircon sales resulted in increases in revenues related to in Tronox legacy operations. On a pro forma basis, net sales for the three months ended March 31, 2020 remained relatively flat in comparison to the same period in 2019.
Net sales by type of product for the three months ended March 31, 2020 and 2019 were as follows:

On a reported basis, for the three months ended March 31, 2020, TiO2 revenue was higher by 109% or $303 million compared to the prior year quarter. The acquisition of Cristal benefited growth by $286 million, or 94%. In addition to the Cristal acquisition, the increase in TiO2 revenue for legacy Tronox operations benefited by a 7% or $21 million increase in sales volumes in legacy Tronox operations offset by a decrease of 1% or $2 million in average selling prices of TiO2. Foreign currency negatively impacted TiO2 revenue by $2 million due to the weakening of the Euro. Zircon revenues benefited by $15 million due to the Cristal acquisition. This increase in Zircon revenues was partially offset by a $14 million decline in legacy Tronox operations compared to the prior year quarter driven by a 16% reduction in average selling prices and a 6% reduction in sales volumes. Feedstock and other products revenues was $28 million higher from the year-ago quarter which includes $26 million related to Cristal. The increase in Feedstock and other products revenues for Tronox legacy operations was primarily driven by higher CP slag volumes.
On a pro forma basis, for the three months ended March 31, 2020, TiO2 revenue increased 2% compared to the prior year driven primarily by a $29 million increase in sales volumes partially offset by a $7 million decrease in average selling prices. Foreign currency negatively impacted TiO2sales by $7 million or 1% due to the weakening of the Euro. Zircon revenues declined $17 million or 21% primarily due to a 16% decline in average sales prices and a 7% decline in sales volumes. Feedstock and other products revenues increased primarily due to higher sales volumes of CP slag.
On both an as reported and pro forma basis, first quarter revenue of 2020 increased 4% when compared to the fourth quarter of 2019 driven by a 7% increase in TiO2 volumes partially offset by a 8% decrease in average selling prices of Zircon.

On a reported basis, our gross margin of $175 million was 24% of net sales compared to 21% of net sales in the year-ago quarter. The increase in gross margin is primarily due to:
the favorable impact of 10 points due to the reduction of production costs, primarily due to lower energy costs and process chemicals costs and improved production synergies;
the net favorable impact of 3 points related to foreign currency primarily due to a favorable impact on cost of goods sold due to the South African rand and Australian dollar partially offset by an unfavorable impact on sales due to the South African rand and Euro;
the inclusion of Cristal’s results, which operates at a lower gross margin than legacy Tronox, reduced gross margin by 7 points due to higher operating costs and lower grade at Cristal mining offset by synergies realized; and
the unfavorable impact of 3 points on gross margin for volume, product mix and sales prices.
On a pro forma basis, our gross margin of $175 million was 24% of net sales compared to 20% of net sales in the year-ago quarter. The increase in gross margin is primarily due to:
the favorable impact of 4 points from reduction of production costs, primarily due to lower energy and process chemicals costs and improved production and cost structures as a result of synergy initiatives;
the net favorable impact of 3 points of foreign currency on cost of goods sold due to the South African rand and Australian dollar;
the unfavorable impact of 2 points caused by a decrease in both TiO2 and Zircon selling prices;
the unfavorable impact of 1 point of foreign currency on sales due to the Euro and South African rand.

On a reported basis, selling, general and administrative expenses increased by $27 million or 40% during the three months ended March 31, 2020 compared to the same period of the prior year. The acquisition of Cristal accounted for $20 million of the increase. In addition to the Cristal expenses were $5 million of higher employee-related costs and a $4 million increase in integration costs partially offset by a $3 million decrease in research and development expenses and lower professional services of $1 million. On a pro forma basis, selling, general and administrative expenses remained consistent period over period.
On both a reported and pro forma basis, we recorded restructuring expenses of $2 million for employee-related costs associated with headcount reductions during the three months ended March 31, 2020. See Note 3 of notes to unaudited condensed consolidated financial statements.
On a reported basis, income from operations for the three months ended March 31, 2020 was $79 million compared to income from operations of $16 million in the prior year period. The increase of $63 million was primarily due to the higher gross margin partially offset by higher SG&A expenses discussed above.
On a pro forma basis, income from operations for the three months ended March 31, 2020 increased $33 million to $79 million from $46 million in the prior year period primarily due to higher gross margin as discussed above.
On a reported basis, adjusted EBITDA as a percentage of net sales was 24% for the three months ended March 31, 2020, an increase of 3 points from 21% in the prior year. The higher gross margin partially offset by the higher SG&A expenses as discussed above were the primary drivers of the year-over-year increase in Adjusted EBITDA percentage.
On a pro forma basis, adjusted EBITDA as a percentage of net sales was 24% for the three months ended March 31, 2020, an increase of 4 points from 20% in the prior year. The higher gross margin as discussed above was the primary driver of the year-over-year increase in Adjusted EBITDA percentage.
On a reported basis, interest expense for the three months ended March 31, 2020 decreased by $4 million compared to the same period of 2019 primarily due to lower average debt outstanding balances and lower average interest rates.
On a pro forma basis, interest expense for the three months ended March 31, 2020 was lower by $10 million compared to the same period of 2019 due to lower average debt levels and lower interest rates in the current period versus the prior year period.

On a reported basis, interest income for the three months ended March 31, 2020 decreased by $6 million compared to the same period in 2019 due to lower cash balances from the use of cash and previously restricted cash in the second quarter of 2019 for the acquisition of the Cristal Transaction. On a pro forma basis, interest income for the three months ended March 31, 2020 remained flat in comparison to the same period in 2019.
On a reported basis, other income (expense), net for the three months ended March 31, 2020 primarily consisted of $13 million of net realized and unrealized foreign currency gains. The foreign currency gains were primarily driven by the South African rand and the Australian dollars used in the remeasurement of our U.S. dollar denominated working capital balances partially offset by the impact of our foreign currency derivatives. In the prior year period, we recognized a $1 million expense for the potential payment to Exxaro equal to any South African capital gains tax assessed on Exxaro in respect of any profit arising to it on the disposal of any of its ordinary shares in Tronox Holdings plc as a result of the Re-domicile Transaction (see Note 20 of notes to unaudited condensed consolidated financial statements for additional information). The payment to Exxaro was fully paid in January 2020.
On a pro forma basis, other income (expense), net for the three months ended March 31, 2020 was higher than the prior year period primarily due to the pro forma results including foreign currency losses for legacy Cristal operations in the prior year, mostly offset by the reasons previously discussed.
We continue to maintain full valuation allowances related to the total net deferred tax assets in the U.S. and Australia. We have full valuation allowances in Australia, Belgium, Brazil, Switzerland, and the U.S.  The provisions for income taxes associated with these jurisdictions include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments. Additionally, we have valuation allowances against other specific tax assets.
On a reported basis, the effective tax rate was 15% and (7)% for the three months ended March 31, 2020 and 2019, respectively. The effective tax rates for the three months ended March 31, 2020 and 2019 are influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, disallowable expenditures, restructuring impacts, and our jurisdictional mix of income at tax rates different than the U.K. statutory rate. On a pro forma basis, the effective tax rate was 15% and 64% for the three months ended March 31, 2020 and 2019, respectively.
Other Comprehensive (Loss) Income
Other comprehensive loss was $270 million for the three months ended March 31, 2020 as compared to none for the prior year period. The increase in loss in 2020 compared to the prior year was primarily driven by unfavorable foreign currency translation adjustments of $188 million in the current year period compared to none in the prior year primarily due to the movement in the South Africa rand coupled with a net loss of $83 million in derivative instruments of which there were no comparable amounts in the prior year.
LiquidityBusiness Environment
The following discussion includes trends and Capital Resourcesfactors that may affect future operating results:

During the current coronavirus pandemic, our operations have been designated as essential to support the continued manufacturing of products such as food and medical packaging, medical equipment, pharmaceuticals, and personal protective gear. As of the end of the quarter, all of our sites were running to planned production levels, excluding South Africa where we elected to shutdown the mining of ilmenite for a period of time near the end of the first quarter of 2020 and into a portion of the second quarter of 2020. During that time, we utilized our existing inventories of ilmenite to operate our smelters which operated at near-full rates to produce chloride slag with a reduced workforce through the 21-day countrywide lockdown period. On April 13, 2020, our South African mines and concentrators were back up and running at full capacity.
Our first quarter revenue increased 4% sequentially driven primarily by higher TiO2 volumes.  Average TiO2 selling prices remained stable, while Zircon average selling prices were 8% lower. The Covid-19 pandemic has impacted, and will continue to impact, our industry and business. Demand for TiO2 in North America has been the most resilient, as we benefit from our exposure to do-it-yourself coatings and packaging applications. Regions hit hardest by the virus have experienced lower than normal demand, including southern Europe, Brazil and India. Zircon demand remains mixed, with recovering volumes in China offset by weaker demand in southern Europe and India. Zircon volumes for the first quarter were in-line with fourth quarter 2019 volumes. Based upon the status of social restrictions, the announced plans for the re-opening of economies around the world, and our conversations with and public statements by our customers, we anticipate declines in second quarter TiO2 volumes versus first quarter 2020, while we expect Zircon volumes for the second quarter to remain largely in line with the first quarter.

Gross margin improved sequentially from the fourth quarter 2019 to the first quarter 2020 due to the favorable impacts of volume and mix, reductions in production costs and favorable impacts of foreign currency on costs. These impacts were partially offset by the negative impacts of average selling prices.
As of September 30, 2017, we had $238March 31, 2020, our total available liquidity was $570 million, available under the $550including $420 million Wells Fargo Revolver and $1.1 billion in cash and cash equivalents. In addition, restricted cash as of September 30, 2017 included the $650equivalents and $150 million proceeds from the Blocked Term Loan discussed above.

Lease Financing

We have capital lease obligations in South Africa, which are payable through 2031 at a weighted average interest rate of approximately 14%. At September 30, 2017available under revolving credit agreements including $123 million available under our Asset Backed Lending ("ABL") facility. Our total debt was $3.2 billion and December 31, 2016, assets recorded under capital lease obligations were $21 million and $7 million, respectively. Related accumulated amortization was $7 million and $6 million at September 30, 2017 and December 31, 2016, respectively. During each of the three and nine months ended September 30, 2017 and 2016, we made principal payments of less than $1 million.

Fair Value

Ournet debt is recorded at historical amounts. At September 30, 2017 and December 31, 2016, the fair value of the New Term Loan Facility was $2.2 billion. At September 30, 2017 and December 31, 2016, the fair value of the Senior Notes due 2022 was $616 million and $544 million, respectively. At September 30, 2017 the fair value of our Senior Notes due 2025 was $461 million. We determined the fair value of the New Term Loan Facility, the Senior Notes due 2022 and the Senior Notes due 2025 using quoted market prices.

Debt Covenants

At September 30, 2017, we hadCompany also has no financial covenants inon its term loan or bonds and only one springing financial covenant on its ABL facility, which we do not expect to be triggered based on our current scenario planning.
On May 1, 2020, Tronox Incorporated, a wholly-owned indirect subsidiary of the Company, issued 6.5% senior secured notes due 2025 for an aggregate principal amount of $500 million (the "6.5%Senior Secured Notes due 2025"). A portion of the proceeds of this debt offering was utilized to repay the $200 million of the Company's outstanding borrowings under its Wells Fargo, RevolverStandard Bank, and the New Term Loan Facility. We were in compliance with all our reporting covenants as of and for the three and nine months ended September 30, 2017.Emirates revolvers.

During the nine months ended September 30, 2016, we amended our lease agreement for our TiO2 pigment facility in Botlek, The Netherlands, which included an option to extend the lease term for an additional 25 years. This amendment increased the estimated useful life used in determining the asset retirement obligation and consequently, we recognized a $10 million reduction to this liability.

Exxaro is entitled to exchange this interest for approximately 3.2% in additional Class B Shares under certain circumstances. Exxaro also has a 26% ownership interest in certain of our other non-operating subsidiaries.

Expected to vest, September 30, 2017  176,472  $4.92 

At September 30, 2017, there was less than $l million of unrecognized compensation expense related to unvested restricted shares which is expected to be recognized over a weighted-average period of 1.1 years. Since the restricted shares were granted only to certain members of our Board, the unrecognized compensation expense was not adjusted for estimated forfeitures. The total fair value of restricted shares that vested during the nine months ended September 30, 2017 was $1 million.

Restricted Share Units (“RSUs”)

During the nine months ended September 30, 2017, we granted RSUs which have time and/or performance conditions. Both the time-based awards and the performance-based awards are classified as equity awards. For the time-based awards, 1,075 RSUs vested immediately, 14,053 RSUs vest ratably over a nine-month period 100,160 RSUs vest ratably over a one-year period and 12,869 RSUs vest ratably over a three-year period, and are valued at the weighted average grant date fair value. For the performance-based awards, 1,145,933 cliff vest at the end of the three years and 12,865 cliff vest at the end of forty months. Included in the performance-based awards are 786,639 RSUs for which vesting is determined based on a relative Total Stockholder Return (“TSR”) calculation over the applicable measurement period. The TSR metric is considered a market condition for which we use a Monte Carlo simulation to determine the grant date fair value. A total of 1,225,697 RSUs were granted, pursuant to an Integration Incentive Award program (the “Integration Incentive Award”) established in connection with the Cristal Transaction, to certain executive officers and managers with significant integration accountability. If the Cristal Transaction does not close by July 1, 2018, then the Integration Incentive Award granted will be cancelled.

The amount will change based on the fair market value of our stock. The total intrinsic value of options exercised during the three and nine months ended September 30, 2017 was less than $1 million. No options were exercised during the three and nine months ending September 30, 2016 and consequently, there was no related intrinsic value. We issue new shares upon the exercise of options. During the three and nine months ended September 30, 2017, we received approximately $1 million in cash for the stock options exercised. As there were no stock options exercised during the three and nine months ended September 30, 2016, no cash was received.

At September 30, 2017, we had no unrecognized compensation expense related to options, adjusted for estimated forfeitures. We did not issue any options during the nine months ended September 30, 2017.

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

During 2012, we established the T-Bucks EPP for the benefit of certain qualifying employees of our South African subsidiaries. We funded a T-Bucks Trust (the “Trust”) with R124 million (approximately $15 million), which was used to acquire Class A Shares. On  May 31, 2017, the shares held by the Trust became fully vested. The Trust sold 546,403 shares in June 2017 on behalf of the participants who elected to receive cash. The remaining participants elected to receive shares.

Long-Term Incentive Plan (“LTIP”)

We have a LTIP for the benefit of certain qualifying employees of Tronox subsidiaries in South Africa and Australia. The LTIP is classified as a cash-settled compensation plan and is re-measured to fair value at each reporting date. We did not have an outstanding liability for LTIP at both September 30, 2017 and December 31, 2016.

17.Pension and Other Postretirement Healthcare Benefits

We sponsor a noncontributory defined benefit retirement plan in the U. S., the qualified retirement plan (the “U.S. Qualified Retirement Plan”). We also have a collective defined contribution plan (a multiemployer plan) in the Netherlands, and a postretirement healthcare plan in South Africa. We had a defined benefit retirement plan in the Netherlands which was settled in the fourth quarter of 2016.

We sponsored a noncontributory defined benefit plan that covered eligible employees of Alkali which became effective from the acquisition date of Alkali, on April 1, 2015 (the “Alkali Qualified Plan”). Our obligations under the Alkali Qualified Plan transferred with the Sale and $5 million in actuarial losses and prior service costs previously included in “Accumulated other comprehensive loss” were recognized as a loss within “Income (loss) from discontinued operations, net of tax” on the Statement of Operations in the third quarter of 2017.

The components of net periodic cost associated with the postretirement healthcare plans was less than $1 million each for the three and nine months ended September 30, 2017 and 2016. The components of net periodic cost associated with the postretirement healthcare plan was $1 million for each of the nine months ended September 30, 2017 and 2016.

For each of the three and nine month periods ended September 30, 2017 and 2016, we contributed $1 million and $3 million, respectively, to The Netherlands multiemployer plan, which was primarily recognized in “Cost of goods sold” in the unaudited Condensed Consolidated Statement of Operations.

18.Related Parties

Exxaro

We have service level agreements with Exxaro for research and development that expired during the third quarter of 2017. Such service level agreements amounted to less than $1 million of expense during each of the three months and nine months ended September 30, 2017 and 2016, which was included in “Selling, general and administrative expense” in the unaudited Condensed Consolidated Statements of Operations. Additionally, we had a professional service agreement with Exxaro related to the Fairbreeze construction project which ended in January 2017. Payments were nil and $1 million, respectively, to Exxaro relating to Fairbreeze duringcombined business, while the three months ended September 30, 2017 and 2016 and less than $1 million and $2 million, respectively, during the nine months ended September 30, 2017 and 2016. These payments were capitalized and included in “Property, plant and equipment, net” in our unaudited Condensed Consolidated Balance Sheets. At both September 30, 2017 and DecemberMarch 31, 2016, we had less than $1 million of related party payables, which were recorded in “Accounts payable” in our unaudited Condensed Consolidated Balance Sheets.

Overview

We are a global leader in the production and marketing of titanium bearing mineral sands and titanium dioxide (“TiO2”) pigment.

TiO2 Segment

We operate three TiO2 pigment facilities at the following locations: Hamilton, Mississippi; Botlek, the Netherlands; and Kwinana, Western Australia, representing an aggregate annual TiO2 production capacity of approximately 465,000 metric tons. TiO2 is 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. Moreover, it is a critical component of everyday consumer applicationsgoods sold due to its superior abilitythe South African rand and Australian dollar;
the unfavorable impact of 2 points caused by a decrease in both TiO2 and Zircon selling prices;
the unfavorable impact of 1 point of foreign currency on sales due to cover or mask other materials effectivelythe Euro and efficiently relative to alternative white pigments and extenders. TiO2 is considered to be a quality of life product, and some research indicates that consumption generally increases as disposable income increases. At present, it is our belief that there is no effective mineral substitute for TiO2 because no other white pigment has the physical properties for achieving comparable opacity and brightness, or can be incorporated as cost effectively. We also operate three separate mining operations: KwaZulu-Natal Sands located in South Africa, Namakwa Sands located in South Africa and Cooljarloo located in Western Australia.African rand.

Our TiO2 business includes the following:

Exploration, mining, and beneficiation of mineral sands deposits;

Production of titanium feedstock and its co-products (including chloride slag, slag fines, rutile, synthetic rutile and leucoxene), pig iron, and zircon;

Production and marketing of TiO2; and

Electrolytic manganese dioxide manufacturing and marketing, which is primarily focused on advanced battery materials and specialty boron products.

Recent Developments


On February 21, 2017, Tronox Limited, The National Titanium Dioxide Company Ltd., a limited company organized underreported basis, selling, general and administrative expenses increased by $27 million or 40% during the lawsthree months ended March 31, 2020 compared to the same period of the Kingdomprior year. The acquisition of Saudi Arabia (“Cristal”), and Cristal Inorganic Chemicals Netherlands Coöperatief   W.A., a cooperative organized under the lawsaccounted for $20 million of the Netherlandsincrease. In addition to the Cristal expenses were $5 million of higher employee-related costs and a wholly owned subsidiary$4 million increase in integration costs partially offset by a $3 million decrease in research and development expenses and lower professional services of Cristal (“Seller”), entered into$1 million. On a Transaction Agreement (the “Transaction Agreement”), pursuant to whichpro forma basis, selling, general and administrative expenses remained consistent period over period.
On both a reported and pro forma basis, we agreed to acquire Cristal’s titanium dioxide businessrecorded restructuring expenses of $2 million for $1.673 billion in cash, subject to a working capital adjustment at closing (the “Cash Consideration”), plus 37,580,000 Class A ordinary shares (“Class A Shares”), par value $0.01 per share, of Tronox Limited (the “Cristal Transaction”). Followingemployee-related costs associated with headcount reductions during the closing of the Cristal Transaction, the Seller will own approximately 24% of the outstanding ordinary shares (including both Class A and Class B) of Tronox Limited.

The Transaction Agreement provides that we must pay to Cristal a termination fee of $100 million if all conditions to closing, other than the financing condition, have been satisfied and the Transaction Agreement is terminated because closing of the Cristal Transaction has not occurred by May 21, 2018. As a result of the refinancing (Seethree months ended March 31, 2020. See Note 113 of notes to unaudited condensed consolidated financial statements), we expectstatements.
On a reported basis, income from operations for the three months ended March 31, 2020 was $79 million compared to financeincome from operations of $16 million in the prior year period. The increase of $63 million was primarily due to the higher gross margin partially offset by higher SG&A expenses discussed above.
On a pro forma basis, income from operations for the three months ended March 31, 2020 increased $33 million to $79 million from $46 million in the prior year period primarily due to higher gross margin as discussed above.
On a reported basis, adjusted EBITDA as a percentage of net sales was 24% for the three months ended March 31, 2020, an increase of 3 points from 21% in the prior year. The higher gross margin partially offset by the higher SG&A expenses as discussed above were the primary drivers of the year-over-year increase in Adjusted EBITDA percentage.
On a pro forma basis, adjusted EBITDA as a percentage of net sales was 24% for the three months ended March 31, 2020, an increase of 4 points from 20% in the prior year. The higher gross margin as discussed above was the primary driver of the year-over-year increase in Adjusted EBITDA percentage.
On a reported basis, interest expense for the three months ended March 31, 2020 decreased by $4 million compared to the same period of 2019 primarily due to lower average debt outstanding balances and lower average interest rates.
On a pro forma basis, interest expense for the three months ended March 31, 2020 was lower by $10 million compared to the same period of 2019 due to lower average debt levels and lower interest rates in the current period versus the prior year period.

On a reported basis, interest income for the three months ended March 31, 2020 decreased by $6 million compared to the same period in 2019 due to lower cash balances from the use of cash and previously restricted cash in the second quarter of 2019 for the acquisition of the Cristal Transaction with our cash on hand inclusive of restricted cash and liquidity from our asset-based syndicated revolving credit facility. The Cristal Transaction is also conditioned uponTransaction. On a pro forma basis, interest income for the receipt of various regulatory approvals, including antitrust clearancethree months ended March 31, 2020 remained flat in numerous jurisdictions. On April 13, 2017, the U.S. Federal Trade Commission (“FTC”) issued a Second Requestcomparison to the Companysame period in 2019.
On a reported basis, other income (expense), net for the three months ended March 31, 2020 primarily consisted of $13 million of net realized and Cristal in connection with its filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and Tronox has substantially complied with the Second Request.unrealized foreign currency gains. The Cristal Transaction, which has been unanimously approved by our board of directors (the “Board”), is expected to closeforeign currency gains were primarily driven by the first quarter 2018, subject to regulatory approvalsSouth African rand and satisfaction of customary closing conditions.

On September 1, 2017, we completed the previously announced saleAustralian dollars used in the remeasurement of our wholly owned subsidiary Tronox Alkali Corporation (“Alkali”) to Genesis Energy, L.P. for proceeds of approximately $1.325 billion in cash, subject to a customary post-closingU.S. dollar denominated working capital adjustment (the “Sale”).balances partially offset by the impact of our foreign currency derivatives. In connection with the Sale,prior year period, we recognized a loss of $233$1 million net of tax, duringexpense for the three and nine months ended September 30, 2017. See Note 2. As a result of the Sale, Alkali’s results of operations have been reported as discontinued operations (see Note 2). We have agreed unconditionally to guarantee the indemnification and performance of the obligations of Tronox U.S. Holdings Inc. (“Tronox Holdings”), a subsidiary of Tronox Limited, under the stock purchase agreement (“Purchase Agreement”). Both Tronox Holdings and Genesis Energy, L.P. have agreed, following the closing, to indemnify the other party for losses arising from certain breaches of the Purchase Agreement and for certain other liabilities, subject to certain limitations. On October 2, 2017, at a special meeting of shareholders of the Company held pursuant to the Transaction Agreement, the Company’s shareholders approved a resolution to issue 37,580,000 Class A Shares to the Seller in connection with the acquisition of Cristal’s TiO2 business, and the resulting acquisition of interests in such Class A Shares by the Seller and certain other persons and entities, at the closing of such acquisition.

In 2012, our Class B ordinary shares (“Class B Shares”) were issuedpotential payment to Exxaro Resources Limited (“Exxaro”) and one of its subsidiaries in consideration for 74% of Exxaro’sequal to any South African mineral sands business.capital gains tax assessed on Exxaro has agreed notin respect of any profit arising to acquireit on the disposal of any voting shares of Tronox Limited if, following such acquisition, Exxaro will have a voting interest in Tronox Limited of 50% or more unless Exxaro brings any proposal to make such an acquisition to the Board on a confidential basis. In the event an agreement regarding the proposal is not reached, Exxaro is permitted to make a takeover offer for all the shares of Tronox Limited not held by affiliates of Exxaro, subject to certain non-waivable conditions. At September 30, 2017 and December 31, 2016, Exxaro held approximately 43% and 44%, respectively, of the voting securities of Tronox Limited. See Note 18 for additional information regarding Exxaro transactions. On March 8, 2017, Exxaro announced its intention to begin pursuing a path to monetize its ownership stake in Tronox over time. On October 10, 2017, Exxaro sold 22,425,000 Class A ordinary shares in an underwritten registered offering (the “Exxaro Share Transaction”). Subsequent to the Exxaro Shares Transaction, Exxaro held approximately 24% of the Company’s voting securities. Presently, Exxaro intends to sell the remainder of its Tronox shares in a staged process over time pursuant to the existing registration statement, subject to market conditions. Exxaro’s sale of Class A ordinary shares does not impact their 26% ownership interest in each of our Tronox KZN Sands (Pty) Ltd. and Tronox Mineral Sands (Pty) Ltd subsidiaries.

During the fourth quarter of 2016, we implemented various steps of an internal corporate reorganization plan to simplify our corporate structure and thereby improve operational, administrative, and commercial synergies within each of our operating segments (the “Corporate Reorganization”). As a result of the Corporate Reorganization, we reduced our cross jurisdictional financing arrangements, eliminated administrative activities and reversed the deferred tax assets related to intercompany interest deductions. The related withholding tax accrual amounts were also reversedHoldings plc as a result of the Corporate Reorganization. Additionally, we reduced our deferred tax assets related to loss carryforwards which will no longer be available to utilize. In connection with the Corporate Reorganization during the first quarter of 2017, Tronox Limited became managed and controlled in the U.K., with no additional impacts to the consolidated provision for income taxes due to the valuation allowances in various jurisdictions. SeeRe-domicile Transaction (see Note 320 of notes to our unaudited condensed consolidated financial statements for additional information.information). The payment to Exxaro was fully paid in January 2020.
On a pro forma basis, other income (expense), net for the three months ended March 31, 2020 was higher than the prior year period primarily due to the pro forma results including foreign currency losses for legacy Cristal operations in the prior year, mostly offset by the reasons previously discussed.
30We continue to maintain full valuation allowances related to the total net deferred tax assets in the U.S. and Australia. We have full valuation allowances in Australia, Belgium, Brazil, Switzerland, and the U.S.  The provisions for income taxes associated with these jurisdictions include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments. Additionally, we have valuation allowances against other specific tax assets.

On a reported basis, the effective tax rate was 15% and (7)% for the three months ended March 31, 2020 and 2019, respectively. The effective tax rates for the three months ended March 31, 2020 and 2019 are influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, disallowable expenditures, restructuring impacts, and our jurisdictional mix of income at tax rates different than the U.K. statutory rate. On a pro forma basis, the effective tax rate was 15% and 64% for the three months ended March 31, 2020 and 2019, respectively.
TableOther Comprehensive (Loss) Income
Other comprehensive loss was $270 million for the three months ended March 31, 2020 as compared to none for the prior year period. The increase in loss in 2020 compared to the prior year was primarily driven by unfavorable foreign currency translation adjustments of Contents$188 million in the current year period compared to none in the prior year primarily due to the movement in the South Africa rand coupled with a net loss of $83 million in derivative instruments of which there were no comparable amounts in the prior year.
Business Environment

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

Our pigment business benefited fromDuring the current coronavirus pandemic, our operations have been designated as essential to support the continued manufacturing of products such as food and medical packaging, medical equipment, pharmaceuticals, and personal protective gear. As of the end of the quarter, all of our sites were running to planned production levels, excluding South Africa where we elected to shutdown the mining of ilmenite for a global industry recovery that began inperiod of time near the end of the first quarter of 2016. To meet healthy2020 and into a portion of the second quarter of 2020. During that time, we utilized our existing inventories of ilmenite to operate our smelters which operated at near-full rates to produce chloride slag with a reduced workforce through the 21-day countrywide lockdown period. On April 13, 2020, our South African mines and concentrators were back up and running at full capacity.
Our first quarter revenue increased 4% sequentially driven primarily by higher TiO2 volumes.  Average TiO2 selling prices remained stable, while Zircon average selling prices were 8% lower. The Covid-19 pandemic has impacted, and will continue to impact, our industry and business. Demand for TiO2 in North America has been the most resilient, as we benefit from our exposure to do-it-yourself coatings and packaging applications. Regions hit hardest by the virus have experienced lower than normal demand, we operated our pigment plants at high utilization rates while matching pigment productionincluding southern Europe, Brazil and India. Zircon demand remains mixed, with recovering volumes to salesin China offset by weaker demand in southern Europe and India. Zircon volumes and keeping inventory at or below normal levels. Global pigment pricing has rebounded with successive gains in each quarter sincefor the first quarter were in-line with fourth quarter 2019 volumes. Based upon the status of 2016. We believe pigment inventories,social restrictions, the announced plans for the re-opening of economies around the world, and our conversations with and public statements by our customers, we anticipate declines in second quarter TiO2 volumes versus first quarter 2020, while we expect Zircon volumes for the second quarter to remain largely in line with the first quarter.

Gross margin improved sequentially from the fourth quarter 2019 to the first quarter 2020 due to the favorable impacts of volume and mix, reductions in production costs and favorable impacts of foreign currency on costs. These impacts were partially offset by the negative impacts of average selling prices.
As of March 31, 2020, our total available liquidity was $570 million, including $420 million in cash and cash equivalents and $150 million available under revolving credit agreements including $123 million available under our Asset Backed Lending ("ABL") facility. Our total debt was $3.2 billion and net debt to trailing-twelve month Adjusted EBITDA pro forma for the Cristal transaction was 3.9x. There are no upcoming maturities on the Company’s term loan or bonds until 2024. The Company also has no financial covenants on its term loan or bonds and only one springing financial covenant on its ABL facility, which we do not expect to be triggered based on our current scenario planning.
On May 1, 2020, Tronox Incorporated, a wholly-owned indirect subsidiary of the Company, issued 6.5% senior secured notes due 2025 for an aggregate principal amount of $500 million (the "6.5%Senior Secured Notes due 2025").

The acquisition of the TiO2 business of Cristal on April 10, 2019 impacts the comparability of the reported results for 2020 compared to 2019. Since Tronox and Cristal have combined their respective businesses effective with the merger date of April 10, 2019, the three months ended March 31, 2020 reflect the results of the combined business, while the three months ended March 31, 2019 includes only the results of the legacy Tronox business. To assist with a discussion of the 2020 and

2019 results on a comparable basis, certain supplemental unaudited pro forma income statement information is provided on a consolidated basis and is referred to as "pro forma information".
The pro forma information has been prepared on a basis consistent with Article 11 of Regulation S-X, assuming the merger and merger-related divestitures of Cristal's North American TiO2 business and the 8120 paper laminate grade had been consummated on January 1, 2018. In preparing this pro forma information, the historical financial information has been adjusted to give effect to pro forma adjustments that are (i) directly attributable to the business combination and other transactions presented herein, such as the merger-related divestitures, (ii) factually supportable, and (iii) expected to have a continuing impact on the combined entity’s consolidated results. The pro forma information is based on management's assumptions and is presented for illustrative purposes and does not purport to represent what the results of operations would actually have been if the business combination and merger-related divestitures had occurred as of the dates indicated or what the results would be for any future periods. Also, the pro forma information does not include the impact of any revenue, cost or other operating synergies in the aggregate, are atperiods prior to the acquisition that may result from the business combination or below normal levels at both customer and producer locations globally resulting in a continued tight supply-demand balance. We continue to use a significant majority of our high grade titanium feedstock for our pigment production and continued to reduce our titanium slag inventories. In addition, we expect zircon sales volumes in 2017 to exceed those of 2016 as we continue to ramp up production at our Fairbreeze mine to match market demand.any related restructuring costs.


We continue to be uniquely tax-advantaged by favorable tax loss carry forwards and other favorable tax positions. We believe these tax-advantaged factors create opportunities for our operations to benefit for years to come. See Note 3 of notes to our unaudited condensed consolidated financial statements for additional information.

On a reported basis, net sales of $722 million for the three months ended March 31, 2020 increased by 85% compared to $390 million for the same period in 2019. The three months ended March 31, 2020 includes $326 million, or 45% revenue growth related to the acquired operations of Cristal. Incremental to the Cristal acquistion, increases in TiO2 sales volumes and higher CP slag volumes partially offset by lower Zircon sales resulted in increases in revenues related to in Tronox legacy operations. On a pro forma basis, net sales for the three months ended September 30, 2017 increased by 28% comparedMarch 31, 2020 remained relatively flat in comparison to the same period in 2016 due to higher selling prices for Pigment of $53 million, Zircon of $8 million and Pig Iron of $4 million. Higher volume and product mix for CP Slag of $12 million, Zircon of $4 million, Pig Iron of $8 million and Ilmenite of $2 million also contributed to the increase in net sales. There was also a favorable change in foreign currency translation of $5 million resulting from Pigment Sales. Volumes and product mix for Pigment were relatively flat.

2019.
Net sales for the nine months ended September 30, 2017 increased by 29% compared to the same period in 2016 primarily due to the impacttype of higher selling prices for Pigment of $142 million, Zircon of $7 million, Pig Iron of $11 million, Natural Rutile of $1 million and Ilmenite of $3 million. Higher volume and product mix for Pigment of $35 million, CP Slag of $34 million, Zircon of $24 million, Pig Iron of $6 million, Natural Rutile of $2 million and Ilmenite of $9 million also contributed to the increase in net sales for the nine months ended September 30, 2017. The impact from foreign currency translation versus the same period in 2016 was insignificant.

Our gross profit margin for the three months ended September 30, 2017March 31, 2020 and 2019 were as follows:

On a reported basis, for the three months ended March 31, 2020, TiO2 revenue was higher by 109% or $303 million compared to the prior year quarter. The acquisition of Cristal benefited growth by $286 million, or 94%. In addition to the Cristal acquisition, the increase in TiO2 revenue for legacy Tronox operations benefited by a 7% or $21 million increase in sales volumes in legacy Tronox operations offset by a decrease of 1% or $2 million in average selling prices of TiO2. Foreign currency negatively impacted TiO2 revenue by $2 million due to the weakening of the Euro. Zircon revenues benefited by $15 million due to the Cristal acquisition. This increase in Zircon revenues was partially offset by a $14 million decline in legacy Tronox operations compared to the prior year quarter driven by a 16% reduction in average selling prices and a 6% reduction in sales volumes. Feedstock and other products revenues was $28 million higher from the year-ago quarter which includes $26 million related to Cristal. The increase in Feedstock and other products revenues for Tronox legacy operations was primarily driven by higher CP slag volumes.
On a pro forma basis, for the three months ended March 31, 2020, TiO2 revenue increased 2% compared to the prior year driven primarily by a $29 million increase in sales volumes partially offset by a $7 million decrease in average selling prices. Foreign currency negatively impacted TiO2sales by $7 million or 1% due to the weakening of the Euro. Zircon revenues declined $17 million or 21% primarily due to a 16% decline in average sales prices and a 7% decline in sales volumes. Feedstock and other products revenues increased primarily due to higher sales volumes of CP slag.
On both an as reported and pro forma basis, first quarter revenue of 2020 increased 4% when compared to the fourth quarter of 2019 driven by a 7% increase in TiO2 volumes partially offset by a 8% decrease in average selling prices of Zircon.

During the three months ended September 30, 2017 we sold the Alkali segment of our operations.  The Alkali results are now shown as discontinued operations and are not includeddeferred tax assets in the tabular results above.U.S. and Australia. We have full valuation allowances in Australia, Belgium, Brazil, Switzerland, and the U.S.  The provisions for income taxes associated with these jurisdictions include no tax benefits with respect to losses incurred and tax expense only to the extent of current tax payments. Additionally, we have valuation allowances against other specific tax assets.
On a reported basis, the effective tax rate was 15% and (7)% for the three months ended September 30, 2017 differs from bothMarch 31, 2020 and 2019, respectively. The effective tax rates for the three months ended September 30, 2016,March 31, 2020 and 2019 are influenced by a variety of factors, primarily income and losses in jurisdictions with valuation allowances, disallowable expenditures, restructuring impacts, and our jurisdictional mix of income at tax rates different than the nineU.K. statutory rate. On a pro forma basis, the effective tax rate was 15% and 64% for the three months ended September 30, 2017March 31, 2020 and 2019, respectively.
Other Comprehensive (Loss) Income
Other comprehensive loss was $270 million for the three months ended March 31, 2020 as compared to none for the prior year period. The increase in loss in 2020 compared to the prior year was primarily driven by unfavorable foreign currency translation adjustments of $188 million in the current year period compared to none in the prior year primarily due to the discrete resultsmovement in the South Africa rand coupled with a net loss of reporting$83 million in derivative instruments of which there were no comparable amounts in the effects of this sale.prior year.

The effective tax rate for the three and nine months ended September 30, 2017 differs from the U.K. statutory rate of 19% primarily due to valuation allowances and income in foreign jurisdictions taxed at rates different than 19%. The effective tax rate for the three and nine months ended September 30, 2016 differs from the Australian statutory rate of 30% primarily due to valuation allowances, income in foreign jurisdictions taxed at rates lower than 30%, and withholding tax accruals on interest income. The income tax provision for the three and nine months ended September 30, 2017 differs from the income tax provision for the three and nine months ended September 30, 2016 due to withholding tax accruals on interest income which we made during 2016.

Historically, we have funded our operations and met our commitments through cash generated by operations. During 2012, 2015operations, issuance of unsecured notes, bank financings and 2017,borrowings under lines of credit. In the next twelve months, we issued a $900 million aggregate principal, 6.375% senior notes due 2020 at par value (the “Senior Notes due 2020”) which was redeemed during the third quarter of 2017, a $600 million aggregate principal amount, 7.50% senior notes due 2022 (the “Senior Notes due 2022”)expect that our operations and a 5.75% senior notes due 2025 for an aggregate principal amount of $450 million (the “Senior Notes due 2025”), respectively. Additionally, during 2013available borrowings under our debt financings and 2017 we obtained a $1.5 billion senior secured term loan (the “ Prior Term Loan”) which was repaid during the third  quarter of 2017 and a $2.2 billion new senior secured first lien term loan facility (the “New Term Loan Facility”), respectively. Seerevolving credit agreements (see Note 1112 of notes to unaudited condensed consolidated financial statements. In connection withstatements) will provide sufficient cash for our operating expenses, capital expenditures, interest payments and debt repayments. This is predicated on our achieving our forecast which could be negatively impacted by items outside of our control, in particular, macroeconomic conditions, including the Cristal Transaction,economic impacts caused by the coronavirus pandemic. If negatives events occur, we refinancedmay need to reduce our capital expenditures and increased our credit facilities lowering our cost of debtreduce operating costs and extended the portfolio’s weighted average yearsother items to maturity. Additionally, we improved our mix of secured and unsecured debt and achieved more favorable covenants. See Note 11 of notesmaintain adequate liquidity.
Working capital (calculated as current assets less current liabilities) was $1.2 billion at March 31, 2020 compared to unaudited condensed consolidated financial statements.

$1.4 billion at December 31, 2019.
As of and for the ninethree months ended September 30, 2017,March 31, 2020, the non-guarantor subsidiaries of our Senior Notes due 2025 represented approximately 23%18% of our total consolidated liabilities, approximately 40%32% of our total consolidated assets, approximately 19%42% of our total consolidated net sales and approximately 38%46% of our Consolidatedconsolidated EBITDA (as such term is defined in the 2025 Indenture). In addition, as of September 30, 2017,March 31, 2020, our non-guarantor subsidiaries had $881$781 million of total consolidated liabilities (including trade payables but excluding intercompany liabilities), all of which would have been structurally senior to the 2025 Notes. See Note 1112 of notes to unaudited condensed consolidated financial statements.

At September 30, 2017,March 31, 2020, we had outstanding letters of credit and bank guarantees and performance bonds, seeof $71 million. See Note 1316 of notes to unaudited condensed consolidated financial statements.

In the next twelve months, we expect that our operations and available borrowings under our revolving credit agreements will provide sufficient cash to fund our operating expenses, capital expenditures, interest payments, debt repayments, and dividends. Working capital (calculated as current assets of continuing operations less current liabilities of continuing operations) was $2.2 billion at September 30, 2017 compared to $614 million at December 31, 2016, an increase of $1.6 billion, which is primarily due to the sale of the Alkali business, the debt refinancing and cash provided by continuing operations of $94 million, partially offset by dividends paid of $17 million and capital expenditures of $63 million.

Principal factors that could affect the availability of our internally-generated funds include (i) the deterioration of our revenues; (ii) an increase in our expenses; or (iii) changes in our working capital requirements. See Note 1 to notes to condensed consolidated financial statements.

Cash and Cash Equivalents

We consider all investments with original maturities of three months or less to be cash equivalents. As of September 30, 2017,March 31, 2020, our cash and cash equivalents were primarily invested in money market funds. We maintain cash and cash equivalents in bank deposit and money market accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are generally highly rated and geographically dispersed, and we have a policy to limit the amount of credit exposure with any one institution. We have not experienced any losses in such accounts and believe we are not exposed to significant credit risk.

Non-U.S. GAAP Financial Measures

EBITDA and Adjusted EBITDA, which are used by management to measure performance, are not presented in accordance with U.S. GAAP. We define EBITDA as net income (loss) excluding the impact of income taxes, interest expense, interest income and depreciation, depletion and amortization. We define Adjusted EBITDA as EBITDA excluding the impact of nonrecurring items such as restructuring charges, gain or loss on debt extinguishments, impairment charges, gains or losses on sale of assets, acquisition-related transaction costs, integration costs, purchase accounting adjustments and pension settlements and curtailment gains or losses. Adjusted EBITDA also excludes non-cash items such as share-based compensation costs and pension and postretirement costs. Additionally, we exclude from Adjusted EBITDA, realized and unrealized foreign currency remeasurement gains and losses.
Management believes that EBITDA is useful to investors, as it is commonly used in the industry as a means of evaluating operating performance. We do not intend for these non-U.Snon-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. Since 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:

Reflectreflect 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;

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

Provideprovide a normalized view of our operating performance by excluding items that are either noncash or infrequently occurring, or non-recurring in nature;

Assist investors in assessing our compliance under our debt instruments; and

occurring.
Adjusted EBITDA is one of the primary measures management uses for planning and budgeting processes, and to monitor and evaluate financial and operating results. In addition, Adjusted EBITDA is a factor in evaluating management’s performance when determining incentive compensation.

Supplemental Pro Forma Information
To assist in the discussion of the 2020 and 2019 results on a comparable basis, certain supplemental unaudited pro forma income statement and adjusted EBITDA information is provided on a consolidated basis. The pro forma information has been prepared on a basis consistent with Article 11 of Regulation S-X, assuming the merger and merger-related divestitures of Cristal's North American TiO2 business and the 8120 paper laminate grade had been consummated on January 1, 2018. The unaudited pro forma financial information reflects certain adjustments related to the acquisition, such as:
(1)conforming the accounting policies of Cristal to those applied by Tronox;
(2)conversion to U.S. GAAP from IFRS for Cristal;
(3)the elimination of transactions between Tronox and Cristal;
(4)recording certain incremental expenses resulting from purchase accounting adjustments, such as inventory step-up amortization, depreciation, depletion and amortization expense in connection with fair value adjustments to property, plant and equipment, mineral leases and intangible assets;

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 ofwith derivative instruments. We do not invest in derivative instruments for speculative purposes, but historically have entered into, and may enter into, derivative transactionsinstruments for hedging purposes in order to reduce the exposure to fluctuations in interest rates, natural gas prices orand exchange rates.

Market 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. Our TiO2 prices may do so in the near term as ore prices and pigment prices are expected to fluctuate over the next few years. We try 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, as well as using varying contract term lengths and selling to a diverse mix of customers by geography and industry to reap the benefits of a diverse portfolio.

Credit Risk

Credit risk is the risk that a borrower or a counterparty will fail to meet their obligations. A significant portion of our liquidity is concentrated in trade accounts receivable that arise from sales of our products to customers. In the case of TiO2, the high level of industry concentration has the potential to impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, industry or other conditions (e.g., the coronavirus pandemic may increase our credit risk as a result of the difficult economic environment). We have significant exposure to credit risk in industries that are affected by cyclical economic fluctuations. We perform ongoing credit evaluations of our customers and use credit risk insurance policies from time to time, as deemed appropriate, to mitigate credit risk but generally do not require collateral. Our contracts typically enable us to tighten credit terms if we perceive additional credit risk andrisk; however, historic losses due to write offs of bad debt have been relatively low. In addition, due to our international operations, in our TiO2 segment, we are subject to potential trade restrictions and sovereign risk in certain countries in which we operate in.operate. We maintain allowances for potential credit losses based on specific customer review and current financial conditions.

During the three months ended September 30, 2017March 31, 2020 and 2016,2019, our ten largest third-party customers represented approximately 35%29% and 25%42%, respectively, of our consolidated net sales. During the ninethree months ended September 30, 2017March 31, 2020 and 2016, our ten largest third-party customers represented approximately 36% and 23%, respectively,2019, no single customer accounted for 10% of our consolidated net sales.

Interest Rate Risk

Interest rate risk arises from the possibility that changes in interest rates will impact our financial results. We are exposed to interest rate risk on our floating rate debt, the New Term Loan Facility, Standard Bank Term Loan Facility, Tikon Loan and Wells Fargo, Standard Bank Revolver, balance.Emirates Revolver and SABB Credit Facility balances. Using a sensitivity analysis as of September 30, 2017,March 31, 2020, a hypothetical 1% increase in interest rates would result in a net increasedecrease to pre-tax lossincome of approximately $4$10 million on an annualized basis. This is due to the fact that earnings on our floating rate financial assets of $1.7 billion$428 million at September 30, 2017 andMarch 31, 2020 would increase by the full 1%, offsetting the impact of a 1% increase in interest expense on our floating rate debt of $1.4 billion.
During 2019, we entered into interest-rate swap agreements for a portion of our New Term Loan Facility, which effectively converts the variable rate to a fixed rate for a portion of the loan. The agreements expire in September 2024. The Company’s objectives in using the interest-rate swap agreements are to add stability to interest expense and Wells Fargo Revolver balance, would each increase by the full 1%.

to manage its exposure to interest rate movements.
Currency Risk

Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact our balance sheets due to the valuetranslation of our assets and liabilities denominated in foreign currencies, as well as our earnings due to the translation of our balance sheets and remeasurementcertain of our subsidiaries’ statements of operations from local currencies to U.S. dollars.dollars, as well as due to remeasurement of assets and liabilities denominated in currencies other than a subsidiary’s functional currency. We manufacture and market our products in a number of countries throughout the world and, as a result, are exposed to changes in foreign currency exchange

rates, particularly in Australia, Brazil, China, South Africa, the Netherlands and the Netherlands.United Kingdom. The exposure is more prevalent in South Africa and Australia as the majority of revenues are earned in U.S. dollars while expenses are primarily incurred in local currencies. Since we are exposed to movements in the South African Randrand and the Australian Dollar versus the U.S. dollar, we may enter into forward contracts to buy and sell foreign currencies as “economic hedges” for these foreign currency transactions.
During 2019, we entered into foreign currency contracts used to hedge non-functional currency sales for our South African subsidiaries and forecasted non-functional currency cost of goods sold for our Australian subsidiaries. These foreign currency contracts are designated as cash flow hedges. Changes to the fair value of these foreign currency contracts are recorded as a component of other comprehensive (loss) income to the extent such contracts are effective, and are recognized in net sales or costs of goods sold in the period in which the forecasted transaction affects earnings or the transactions are no longer probable of occurring.
38As of March 31, 2020, we had notional amounts of (i) 2.9 billion South African rands that expire between April 29, 2020 and February 25, 2021 to reduce the exposure of our South African subsidiaries’ third party sales to fluctuations in currency rates, and (ii) 691 million Australian dollars that expire between April 29, 2020 and December 30, 2021 to reduce the exposure of our Australian subsidiaries’ cost of sales to fluctuations in currency rates. At March 31, 2020,  the unrealized net loss associated with these open contracts of approximately $30 million is included in "Accumulated other comprehensive loss” on the unaudited Condensed Consolidated Balance Sheet.

We enter into foreign currency contracts for the South African rand and Australian dollar to reduce exposure of our foreign affiliates’ balance sheet to fluctuations in foreign currency rates. At March 31, 2020, the fair value of the foreign currency contracts was a loss of $10 million.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of September 30, 2017, our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), has conducted an evaluation of our disclosure controls and procedures.

The classification of TiO2 as a Category 2 Carcinogen in the European Union could result in more stringent regulatory control with respect to TiO2.

In May 2016, France’s competent authority under the EU’s Registration, Evaluation, Authorization and Restrictions of Chemicals (“REACH”) submitted a proposal to the European Chemicals Agency ("ECHA") that would classify TiO2 as carcinogenic in humans by inhalation. The Company together with other companies and trade associations representing the TiO2 industry and industries consuming our products, submitted comments opposing the classification, based on evidence from epidemiological and other scientific studies. On October 12, 2017, ECHA’s Committee for Risk Assessment (“RAC”) released a written opinion dated September 14, 2017 stating that based on the scientific evidence it reviewed, there is sufficient grounds to classify TiO-2 under the EU’s Classification, Labelling and Packaging Regulation (“CLP”) as a Category 2 Carcinogen , but only with a hazard statement describing the risk by inhalation. The European Commission will review the RAC’s formal recommendation to determine what regulatory measures, if any, should be taken. If the European Commission decides to adopt this classification, it could require that products manufactured with TiO2 be classified as containing carcinogenic materials, which could impact our business by inhibiting the marketing of products containing TiO2 to consumers, and subject our manufacturing operations to new regulations that could increase costs. Any classification, use restriction or authorized requirement for use imposed by the ECHA could have additional effects under other EU laws (e.g., those affecting medical and pharmaceutical applications, cosmetics, food packaging and food additives) and/or trigger heightened regulatory scrutiny in countries and local jurisdictions outside the EU based on health and safety grounds. It is also possible that heightened regulatory scrutiny would lead to claims by consumers or those involved in the production of such products alleging adverse health impacts.

In general, an “ownership change” would occur ifCompany, will be leaving the Company to pursue other opportunities effective as of June 5, 2020. Since joining the Company on April 2, 2018, Mr. Loughran has been a valuable member of the Company’s “5-percent shareholders,” as defined under Section 382management team, with responsibility over financial reporting and playing a leading role in all aspects of the Code, including certain groups of persons treated as “5-percent shareholders,” collectively increased their ownership in the Company by more than 50 percentage points over a rolling three-year period. On October 10, 2017, Exxaro sold 22,425,000 Class A ordinary shares in an underwritten registered offering (the “Exxaro Share Transaction”).
