Any references to the “Company” “we” “us” or “our” as of a date prior to October 19, 2004 (the date of our Company’s formation) are to Huntsman Holdings, LLC and its subsidiaries (including their respective predecessors). In this report, “Huntsman International” refers to Huntsman International LLC (our 100% owned subsidiary) and, unless the context otherwise requires, its subsidiaries; “AAC” refers to Arabian Amines Company, our consolidated manufacturing joint venture with the Zamil Group; “HPS” refers to Huntsman Polyurethanes Shanghai Ltd. (our consolidated splitting joint venture with Shanghai Chlor-Alkali Chemical Company, Ltd); “Sasol-Huntsman” refers to Sasol-Huntsman GmbH and Co. KG (our consolidated joint venture with Sasol that owns and operates a maleic anhydride facility in Moers, Germany); and “SLIC” refers to Shanghai Liengheng Isocyanate Company (our unconsolidated manufacturing joint venture with BASF and three Chinese chemical companies). In this report, we may use, without definition, the common names of competitors or other industry participants. We may also use the common names or abbreviations for certain chemicals or products. Description of Business We are a global manufacturer of differentiated organic chemical products. We operate in four segments: Polyurethanes, Performance Products, Advanced Materials and Textile Effects. Our products comprise a broad range of chemicals and formulations, which we market globally to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, personal care and hygiene, durable and non‑durable consumer products, digital inks, electronics, medical, packaging, coatings and construction, power generation, refining, synthetic fiber, textile chemicals and dye industries. We are a leading global producer in many of our key product lines, including MDI, amines, surfactants, maleic anhydride, epoxy‑based polymer formulations, textile chemicals and dyes. Company Our Company, a Delaware corporation, was formed in 2004 to hold the Huntsman businesses, which were founded by Jon M. Huntsman. Mr. Huntsman founded the predecessor to our Company in 1970 as a small polystyrene plastics packaging company. Since then, we have grown through a series of significant acquisitions and now own a global portfolio of businesses. Jon M. Huntsman served as the Executive Chairman of our Company until December 31, 2017, at which time Peter Huntsman, our Chief Executive Officer, was appointed to the role of Chairman of the Board. Jon M. Huntsman served as Director and Chairman Emeritus until his passing on February 2, 2018. Currently, we operate all of our businesses through Huntsman International, our 100% owned subsidiary. Huntsman International is a Delaware limited liability company and was formed in 1999. Recent Developments Separation and Deconsolidation of Venator In August 2017, we separated the P&A Business and conducted an IPO of ordinary shares of Venator, formerly a wholly-owned subsidiary of Huntsman. Additionally, in December 2017, we conducted a secondary offering of Venator ordinary shares. All of such ordinary shares were sold by Huntsman, and Venator did not receive any proceeds from the offerings. Venator’s ordinary shares began trading on The New York Stock Exchange under the symbol “VNTR” on August 3, 2017. On January 3, 2018, the underwriters purchased an additional 1,948,955 Venator ordinary shares pursuant to their over-allotment option, which reduced Huntsman’s ownership interest in Venator to approximately 53%. Beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations. During the third quarter of 2018, we recognized a net after tax valuation allowance of $270 million to adjust the carrying amount of the assets and liabilities held for sale and the amount of accumulated comprehensive income recorded in equity related to Venator to the lower of cost or estimated fair value, less cost to sell. On December 3, 2018, we sold an aggregate of 4,334,389, or 4%, of Venator ordinary shares to Bank of America N.A. at a price to be determined based on the average of the daily volume weighted average price of Venator ordinary shares over an agreed period. Over this agreed period, we received aggregate proceeds of $19 million, $16 million of which was received in the first quarter of 2019. This transaction allowed us to deconsolidate Venator beginning in December 2018. Following this transaction, we retained approximately 49% ownership in Venator. In connection with the deconsolidation of Venator, we recorded a pretax loss of $427 million in discontinued operations to record our remaining ownership interest in Venator at fair value. We elected the fair value option to account for our equity method investment in Venator post deconsolidation. Accordingly, at December 31, 2018, we recorded a pretax loss of $57 million to record our equity method investment in Venator at fair value. This loss was recorded in “Fair value adjustments to Venator investment” on our consolidated statements of operations. For more information, see “Note 4. Discontinued Operations and Business Dispositions—Separation and Deconsolidation of Venator.” Unsecured Revolving Credit Facility On May 21, 2018, Huntsman International entered into the 2018 Revolving Credit Facility. Borrowings under the 2018 Revolving Credit Facility will bear interest at the rates specified in the credit agreement governing the 2018 Revolving Credit Facility, which will vary based on the type of loan and Huntsman International’s debt ratings. Unless earlier terminated, the 2018 Revolving Credit Facility will mature in May 2023. Huntsman International may increase the 2018 Revolving Credit Facility commitments up to an additional $500 million, subject to the satisfaction of certain conditions. See “Note 14. Debt—Direct and Subsidiary Debt—Credit Facility.” In connection with entering into the 2018 Revolving Credit Facility, Huntsman International terminated all commitments and repaid all obligations under the Prior Credit Facility. In addition, we recognized a loss of early extinguishment of debt of $3 million. Upon the termination of the Prior Credit Facility, all guarantees of the obligations under the Prior Credit Facility were terminated, and all liens granted under the Prior Credit Facility were released. Share Repurchase Program On February 7, 2018 and on May 3, 2018, our Board of Directors authorized us to repurchase up to an additional $950 million in shares of our common stock in addition to the $50 million remaining under our September 2015 share repurchase authorization. During the year ended December 31, 2018, we repurchased 10,405,457 shares of our common stock for approximately $276 million, excluding commissions, under the repurchase program. From January 1, 2019 through January 31, 2019, we repurchased an additional 537,018 shares of our common stock for approximately $11 million, excluding commissions. Demilec Acquisition On April 23, 2018, we acquired 100% of the outstanding equity interests of Demilec for approximately $353 million, including working capital adjustments, in an all-cash transaction which was funded from our Prior Credit Facility and our U.S. A/R Program. Demilec is a leading North American manufacturer and distributor of spray polyurethane foam formulations for residential and commercial applications. The acquired business is being integrated into our Polyurethanes segment. See “Note 3. Business Combination.” Huntsman Corporation and Huntsman International Financial Statements Except where otherwise indicated, these notes relate to the consolidated financial statements for both our Company and Huntsman International. The differences between our consolidated financial statements and Huntsman International’s consolidated financial statements relate primarily to the following: · purchase accounting recorded at our Company for the 2003 step‑acquisition of Huntsman International Holdings LLC, the former parent company of Huntsman International that was merged into Huntsman International in 2005; · the different capital structures; and · a note payable from Huntsman International to us.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Asset Retirement Obligations We accrue for asset retirement obligations, which consist primarily of landfill capping, closure and post‑closure costs, asbestos abatement costs, demolition and removal costs and leasehold remediation costs, in the period in which the obligations are incurred. Asset retirement obligations are accrued at estimated fair value. When the liability is initially recorded, we capitalize the cost by increasing the carrying amount of the related long‑lived asset. Over time, the liability is accreted to its estimated settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations were $11 million and $9 million at December 31, 2018 and 2017, respectively. Carrying Value of Long‑Lived Assets We review long‑lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability is based upon current and anticipated undiscounted cash flows, and we recognize an impairment when such estimated cash flows are less than the carrying value of the asset. Measurement of the amount of impairment, if any, is based upon the difference between carrying value and fair value. Fair value is generally estimated by discounting estimated future cash flows using a discount rate commensurate with the risks involved or selling price of assets held for sale. See “Note 12. Restructuring, Impairment and Plant Closing Costs.” Cash and Cash Equivalents We consider cash in checking accounts and cash in short‑term highly liquid investments with remaining maturities of three months or less at the date of purchase, to be cash and cash equivalents. Cash flows from financing activities from discontinued operations are not presented separately in our consolidated statements of cash flows. Cost of Goods Sold We classify the costs of manufacturing and distributing our products as cost of goods sold. Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold. Derivatives and Hedging Activities All derivatives, whether designated in hedging relationships or not, are recorded on our balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged items are recognized in earnings. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded in accumulated other comprehensive loss, to the extent effective, and will be recognized in the income statement when the hedged item affects earnings. Changes in the fair value of the hedge in the net investment of certain international operations are recorded in other comprehensive income (loss), to the extent effective. The effectiveness of a cash flow hedging relationship is established at the inception of the hedge, and after inception we perform effectiveness assessments at least every three months. A derivative designated as a cash flow hedge is determined to be effective if the change in value of the hedge divided by the change in value of the hedged item is within a range of 80% to 125%. Hedge ineffectiveness in a cash flow hedge occurs only if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. For a derivative that does not qualify or has not been designated as a hedge, changes in fair value are recognized in earnings. Environmental Expenditures Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean‑up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See “Note 20. Environmental, Health and Safety Matters.” Equity Method Investments We account for our equity investments where we own a non-controlling interest, but exercise significant influence, under the equity method of accounting. Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. We elected the fair value option to account for our equity method investment in Venator. For more information, see “Note 4. Discontinued Operations and Business Dispositions.” The change in the fair value related to our equity method investment in Venator is presented in “Fair value adjustments to Venator investment” on the consolidated statements of operations. Foreign Currency Translation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss. If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three-year period), the U.S. dollar is considered to be the functional currency and gains and losses from remeasurement to the U.S. dollar from the local currency are included in the statement of operations. Where a subsidiary’s operations are effectively run, managed, financed and contracted in U.S. dollars, such as certain finance subsidiaries outside of the U.S., the U.S. dollar is considered to be the functional currency. Foreign currency transaction gains and losses are recorded in other operating (income) expense, net in our consolidated statements of operations and were gains of $3 million, $5 million and $2 million for the years ended December 31, 2018, 2017 and 2016, respectively. Income Taxes We use the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial and tax reporting purposes. We evaluate deferred tax assets to determine whether it is more likely than not that they will be realized. Valuation allowances are reviewed on a tax jurisdiction basis to analyze whether there is sufficient positive or negative evidence to support a change in judgment about the realizability of the related deferred tax assets for each jurisdiction. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the period limits our ability to consider other subjective evidence such as our projections for the future. Changes in expected future income in applicable jurisdictions could affect the realization of deferred tax assets in those jurisdictions. On December 22, 2017, the U.S. Tax Reform Act was signed into law. The U.S. Tax Reform Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21%, effective January 1, 2018, repealing the deduction for domestic production activities and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the U.S. Tax Reform Act, the Company recorded net tax benefits of $135 million (a provisional tax benefit of $137 million in 2017 offset by a final tax expense of $2 million in 2018) due to a remeasurement of deferred U.S. tax assets and liabilities and net tax expense of $115 million (a provisional tax expense of $85 million in 2017, a $29 million final federal tax expense in 2018 and a $1 million state tax expense in 2018) due to the transition tax on deemed repatriation of deferred foreign income. Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more‑likely‑than‑not to be realized based on the merits of the position under tax law, in order to recognize an income tax benefit. This requires us to make significant judgments regarding the merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more‑likely‑than‑not we are required to make judgments and apply assumptions to measure the amount of the tax benefits to recognize. These judgments are based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in our consolidated financial statements. We have no need for, or change in, any unrecognized tax positions due to the U.S. Tax Reform Act. For further information concerning taxes, see “Note 18. Income Taxes.” Intangible Assets and Goodwill Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight‑line method over the estimated useful lives or the life of the related agreement as follows: Patents and technology 5 ‑ 30 years Trademarks 9 ‑ 30 years Licenses and other agreements 5 ‑ 15 years Other intangibles 5 ‑ 15 years Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not subject to any method of amortization, but is tested for impairment annually (at the beginning of the third quarter) and when events and circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When the fair value is less than the carrying value of the related reporting unit, we are required to reduce the amount of goodwill through a charge to earnings. Fair value is estimated using the market approach, as well as the income approach based on discounted cash flow projections. Goodwill has been assigned to reporting units for purposes of impairment testing. The following table summarizes the changes in the carrying amount of goodwill for year ended December 31, 2018 (dollars in millions): Performance Advanced Polyurethanes Products Materials Total Balance as of January 1, 2018 $ 40 $ 17 $ 83 $ 140 Goodwill acquired during year(1) 142 — — 142 Foreign currency effect on balance (9) (1) 3 (7) Balance as of December 31, 2018 $ 173 $ 16 $ 86 $ 275 (1) This reflects net amounts, including adjustments related to preliminary valuations of acquisition assets and liabilities. Inventories Inventories are stated at the lower of cost or market, with cost determined using LIFO, first‑in first‑out, and average costs methods for different components of inventory. Legal Costs We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred. Net Income Per Share Attributable to Huntsman Corporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income available to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities. Basic and diluted income per share is determined using the following information (in millions): Year ended December 31, 2018 2017 2016 Numerator: Basic and diluted income from continuing operations: Income from continuing operations attributable to Huntsman Corporation $ 764 $ 478 $ 334 Basic and diluted net income: Net income attributable to Huntsman Corporation $ 337 $ 636 $ 326 Denominator: Weighted average shares outstanding 238.1 238.4 236.3 Dilutive shares: Stock-based awards 3.5 5.5 3.3 Total weighted average shares outstanding, including dilutive shares 241.6 243.9 239.6 Additional stock‑based awards of 0.8 million, 0.8 million and 5.7 million weighted average equivalent shares of stock were outstanding during the years ended December 31, 2018, 2017 and 2016, respectively. However, these stock‑based awards were not included in the computation of diluted earnings per share for the respective periods mentioned because the effect would be anti‑dilutive. Other Noncurrent Assets Periodic maintenance and repairs applicable to major units of manufacturing facilities (a “turnaround”) are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround. Principles of Consolidation Our consolidated financial statements include the accounts of our wholly owned and majority owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated. Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight‑line method over the estimated useful lives or lease term as follows: Buildings and equipment 5 ‑ 50 years Plant and equipment 3 ‑ 30 years Furniture, fixtures and leasehold improvements 5 ‑ 20 years Interest expense capitalized as part of plant and equipment was $4 million, $9 million and $12 million for the years ended December 31, 2018, 2017 and 2016, respectively. Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired. Reclassifications Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform with the current presentation. These reclassifications include the presentation of the other components of net periodic pension cost and net periodic postretirement cost, other than service costs, within other nonoperating income in accordance with Accounting Standards Update (“ASU”) No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . We previously presented these amounts within cost of goods sold and selling, general and administrative expenses. See “—Accounting Pronouncements Adopted During 2018.” Pursuant to ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , we began including the change in restricted cash as part of the change in cash and equivalents when reconciling the beginning-of-period and end-of-period total amounts on the statements of cash flows beginning in 2018. We previously presented changes in restricted cash as an investing activity in the statements of cash flows. See “ — Accounting Pronouncements Adopted During 2018.” Revenue Recognition We generate substantially all of our revenue through product sales in which revenue is recognized at a point in time. We recognize revenue when control of the promised goods is transferred to our customers. Control of goods usually passes to the customer at the time shipment is made. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. See “Note 23. Revenue Recognition.” Securitization of Accounts Receivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities (“SPE”) in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in both U.S. dollars and euros. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14. Debt—Direct and Subsidiary Debt—A/R Programs.” Stock‑Based Compensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant‑date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 22. Stock‑Based Compensation Plan.” Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Accounting Pronouncements Adopted During 2018 In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014‑09, Revenue from Contracts with Customers (Topic 606) , outlining a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and supersedes most current revenue recognition guidance. In March 2016, the FASB issued ASU No. 2016‑08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , clarifying the implementation guidance on principal versus agent considerations, in April 2016, the FASB issued ASU No. 2016‑10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , clarifying the implementation guidance on identifying performance obligations in a contract and determining whether an entity’s promise to grant a license provides a customer with either a right to use the entity’s intellectual property (which is satisfied at a point in time) or a right to access the entity’s intellectual property (which is satisfied over time), in May 2016, the FASB issued ASU No. 2016‑12, Revenue from Customers (Topic 606): Narrow‑Scope Improvements and Practical Expedients , providing clarifications and practical expedients for certain narrow aspects in Topic 606, and in December 2016, the FASB issued ASU 2016‑20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers . The amendments in these ASUs are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The amendments in ASU No. 2014‑09, ASU No. 2016‑08, ASU No. 2016‑10, ASU No. 2016‑12 and ASU No. 2016‑20 should be applied retrospectively. On January 1, 2018, we adopted the amendments in ASU No. 2014‑09, ASU No. 2016‑08, ASU No. 2016‑10, ASU No. 2016‑12 and ASU No. 2016‑20 to all current revenue contracts using the modified retrospective approach, and the initial adoption of these amendments did not have an impact on our consolidated financial statements. As a result of the adoption of these amendments, we revised our accounting policy for revenue recognition as detailed in “Note 23. Revenue Recognition.” In January 2016, the FASB issued ASU No. 2016‑01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities . The amendments in this ASU require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. On January 1, 2018, we adopted the amendments in ASU No. 2016‑01 and upon transition recorded a cumulative-effect adjustment of approximately $10 million, net of tax, relating to prior years’ changes in fair value of equity investments from other comprehensive income to retained earnings. Beginning in the first quarter of 2018, we also started recognizing the current period change in fair value of equity investments in net income. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The amendments in this ASU clarify and include specific guidance to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The amendments in this ASU should be applied using a retrospective transition method to each period presented. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016‑18, Statement of Cash Flows (Topic 230): Restricted Cash . The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning‑of‑period and end‑of‑period total amounts shown on the statement of cash flows. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, and interim period within those fiscal years. The amendments in this ASU were applied using a retrospective transition method to each period presented. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017‑01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of this ASU did not have a significant impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The amendments in this ASU require that an employer report the service cost component of net periodic pension cost and net periodic postretirement benefit cost in the same line items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside of income from operations. The amendments in this ASU also allow only the service cost component to be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit cost in assets. We adopted the amendments in this ASU effective January 1, 2018, which impacted the presentation of our consolidated financial statements. Our previous presentation of service cost components was consistent with the amendments in this ASU. However, we now present the other components within other income, net, whereas we previously presented these within cost of goods sold and selling, general and administrative expenses. In August 2018, the FASB issued ASU No. 2018‑13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this ASU modify certain disclosure requirements on fair value measurements in Topic 820 to improve the effectiveness of such disclosures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We early adopted the removed and modified disclosures in this ASU for the year ended December 31, 2018, and they did not have a significant impact on our consolidated financial statements. We elected to delay the adoption of the additional disclosures in this ASU until their effective date, but do not expect the adoption of the additional disclosures in this ASU to have a significant impact on our consolidated financial statements. Accounting Pronouncements Pending Adoption in Future Periods In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The amendments in this ASU will increase transparency and comparability among entities by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this ASU will require lessees to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 , providing an optional transition practical expedient to not evaluate under Topic 842 existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840, and in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements , providing an optional transition method allowing entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The amendments in these ASUs are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early application of the amendments in these ASUs is permitted for all entities. Reporting entities can elect to recognize and measure leases under these amendments at the beginning of the earliest period presented using a modified retrospective approach or otherwise elect the transition method provided under ASU No. 2018-11. We are currently evaluating the impact of the adoption of the amendments in these ASUs on our consolidated financial statements. Based on our preliminary assessment the estimated right-of-use asset and lease liability that we will recognize on our balance sheet upon adoption will be approximately $400 million to $450 million. This estimate could change pending the finalization of the incremental borrowing rate for certain leases. We are evaluating key policy elections and considerations under the amendments in these ASUs and are developing internal policies to address these amendments. In August 2017, the FASB issued ASU No. 2017‑12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships as well as the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements to increase the understandability of the results of an entity’s intended hedging strategies. The amendments in this ASU also include certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted in any interim period after the issuance of this ASU. Transition requirements and elections should be applied to hedging relationships existing on the date of adoption. For cash flow and net investment hedges, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness, and the amended presentation and disclosure guidance is required only prospectively. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018‑14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans . The amendments in this ASU modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures and adding disclosure requirements identified as relevant. The amendments in this ASU are effective for fiscal years ending after December 15, 2020 and should be applied on a retrospective basis to all periods presented. Early adoption is permitted. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated

BUSINESS COMBINATION
BUSINESS COMBINATION	3 . BUSINESS COMBINATION On April 23, 2018, we acquired 100% of the outstanding equity interests of Demilec for approximately $353 million, including working capital adjustments, in an all-cash transaction, which was funded from our Prior Credit Facility and our U.S. A/R Program. Demilec is a leading North American manufacturer and distributor of spray polyurethane foam formulations for residential and commercial applications. The acquired business was integrated into our Polyurethanes segment. Transaction costs charged to expense related to this acquisition were approximately $5 million in 2018 and were recorded in other operating expense (income), net in our consolidated statements of operations. The Demilec Acquisition was aligned with our stated strategy to grow our downstream polyurethanes business and leverage our global platform to expand Demilec’s portfolio of spray polyurethane foam formulations into international markets. We have accounted for the Demilec Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The preliminary allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions): Fair value of assets acquired and liabilities assumed: Cash paid for Demilec Acquisition in Q2 2018 $ 357 Purchase price adjustment received in Q3 2018 (4) Net acquisition cost $ 353 Cash $ 1 Accounts receivable 31 Inventories 23 Prepaid expenses and other current assets 1 Property, plant and equipment, net 21 Intangible assets 177 Goodwill 142 Accounts payable (16) Accrued liabilities (3) Deferred income taxes (22) Other noncurrent liabilities (2) Total fair value of net assets acquired $ 353 The acquisition cost allocation is preliminary pending final determination of the fair value of assets acquired and liabilities assumed, primarily related to the final valuation of deferred taxes. As a result of a preliminary valuation of the assets and liabilities, reallocations were made in certain property, plant and equipment, intangible asset, goodwill and deferred tax balances. Intangible assets acquired included in this preliminary allocation consist primarily of trademarks, trade secrets and customer relationships, all of which are being amortized over 15 years. For purposes of this preliminary allocation of fair value, we have assigned any excess of the acquisition cost of historical carrying values to goodwill. During the third quarter of 2018, we received $4 million related to the settlement of certain purchase price adjustments. These purchase price adjustments were allocated to goodwill in the preliminary acquisition cost allocation. The estimated goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets, and synergies. It is possible that material changes to this preliminary purchase price allocation could occur. The acquired business had revenues and net income of $142 million and $5 million, respectively, for the period from the date of acquisition to December 31, 2018. If this acquisition were to have occurred on January 1, 2017, the following estimated pro forma revenues, net income, net income attributable to Huntsman Corporation and Huntsman International and income per share for Huntsman Corporation would have been reported (dollars in millions): Pro Forma (Unaudited) Year ended December 31, 2018 2017 Revenues $ 9,437 $ 8,523 Net income 639 728 Net income attributable to Huntsman Corporation 326 623 Income per share: Basic 1.37 2.61 Diluted 1.35 2.55 Pro Forma (Unaudited) Year ended December 31, 2018 2017 Revenues $ 9,437 $ 8,523 Net income 625 721 Net income attributable to Huntsman International 312 616

DISCONTINUED OPERATIONS AND BUSINESS DISPOSITIONS
DISCONTINUED OPERATIONS AND BUSINESS DISPOSITIONS	4. Separation and Deconsolidation of Venator In August 2017, we separated the P&A Business and conducted an IPO of ordinary shares of Venator, formerly a wholly-owned subsidiary of Huntsman. Additionally, in December 2017, we conducted a secondary offering of Venator ordinary shares . All of such ordinary shares were sold by Huntsman, and Venator did not receive any proceeds from the offerings. On January 3, 2018, the underwriters purchased an additional 1,948,955 Venator ordinary shares pursuant to their over-allotment option, which reduced Huntsman’s ownership interest in Venator to approximately 53%. Beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations. During the third quarter of 2018, we recognized a net after tax valuation allowance of $270 million to adjust the carrying amount of the assets and liabilities held for sale and the amount of accumulated comprehensive income recorded in equity related to Venator to the lower of cost or estimated fair value, less cost to sell. On December 3, 2018, we sold an aggregate of 4,334,389, or 4%, of Venator ordinary shares to Bank of America N.A. at a price to be determined based on the average of the daily volume weighted average price of Venator ordinary shares over an agreed period. Over this agreed period, we received aggregate proceeds of $19 million, $16 million of which was received in the first quarter of 2019. This transaction allowed us to deconsolidate Venator beginning in December 2018. Following this transaction, we retained approximately 49% ownership in Venator In August 2017, we entered into a separation agreement, a transition services agreement (“TSA”) and a registration rights agreement with Venator to effect the Separation and provide a framework for a short term set of transition services as well as a tax matters agreement and an employee matters agreement. Pursuant to the TSA, we will, for a limited time following the Separation, provide Venator with certain services and functions that the parties have historically shared, including administrative, payroll, human resources, data processing, environmental, health and safety, financial audit support, financial transaction support, marketing support, information technology systems and various other corporate and support services. We may also provide Venator with additional services that Venator and Huntsman may identify from time to time in the future. In general, the services began following the Separation and cover a period not expected to exceed 24 months; however, Venator may terminate individual services provided by us under the TSA early, as it becomes able to operate its business without such services. The following table summarizes the major classes of assets and liabilities constituting assets and liabilities held for sale as of December 31, 2017: Carrying amounts of major classes of assets held for sale: Accounts receivable $ 380 Inventories 454 Other current assets 318 Property, plant and equipment, net 1,424 Deferred income taxes 158 Other noncurrent assets 146 Total assets held for sale $ 2,880 Carrying amounts of major classes of liabilities held for sale: Accounts payable $ 385 Accrued liabilities 236 Other current liabilities 25 Long-term debt 746 Other noncurrent liabilities 300 Total liabilities held for sale $ 1,692 The following table summarizes major classes of line items constituting pretax and after-tax income of discontinued operations.

Therefore, the summarized financial data only includes information for Venator applicable to the period from January 1, 2018 through December 2, 2018. Sale of European Surfactants Manufacturing Facilities On December 30, 2016, our Performance Products segment completed the sale of its European surfactants business to Innospec Inc. for $199 million in cash plus our retention of trade receivables and payables for an enterprise value of $225 million. Under the terms of the transaction, Innospec acquired our manufacturing facilities located in Saint-Mihiel, France; Castiglione delle Stiviere, Italy; and Barcelona, Spain. We remain committed to our global surfactants business, including in the U.S. and Australia, where our differentiated surfactants businesses are backward integrated into essential feedstocks. Upon closing, we entered into supply and long-term tolling arrangements with Innospec in order to continue marketing certain core products strategic to our global agrochemicals, lubes and certain other businesses. In connection with this sale, we recognized a pre-tax gain in the fourth quarter of 2016 of $98 million which was reflected in other operating income, net on the consolidated statements of operations. This business is not presented as discontinued operations as it was not considered a strategic shift in our operations.

VARIABLE INTEREST ENTITIES
VARIABLE INTEREST ENTITIES	8. VARIABLE INTEREST ENTITIES We evaluate our investments and transactions to identify variable interest entities for which we are the primary beneficiary. We hold a variable interest in the following joint ventures for which we are the primary beneficiary: · Rubicon LLC is our 50%-owned joint venture with Lanxess that manufactures products for our Polyurethanes and Performance Products segments. The structure of the joint venture is such that the total equity investment at risk is not sufficient to permit the joint venture to finance its activities without additional financial support. By virtue of the operating agreement with this joint venture, we purchase a majority of the output, absorb a majority of the operating costs and provide a majority of the additional funding. · AAC is our 50%-owned joint venture with Zamil group that manufactures products for our Performance Products segment. As required in the operating agreement governing this joint venture, we purchase all of AAC’s production and sell it to our customers. Substantially all of the joint venture’s activities are conducted on our behalf. · Sasol‑Huntsman is our 50%‑owned joint venture with Sasol that owns and operates a maleic anhydride facility in Moers, Germany. This joint venture manufactures products for our Performance Products segment. The joint venture uses our technology and expertise, and we bear a disproportionate amount of risk of loss due to a related‑party loan to Sasol‑Huntsman for which we bear the default risk.

In connection with this plan, we recorded restructuring reserves covering, among other things, a non-cancelable long-term service agreement. In the fourth quarter of 2018, we settled this agreement in exchange for the payment of $10 million, $8 million of which will be paid in 2019 and $2 million will be paid in 2023. In connection with this settlement, we reversed the related restructuring reserve and recorded a net credit of $29 million in the fourth quarter of 2018. In addition, during 2018, we recorded a credit of $4 million primarily related to a gain on the sale of land at the Basel, Switzerland site. Our Corporate and other segment recorded restructuring expense of $15 million in 2018 related to corporate initiatives. 2017 Restructuring Activities In September 2011, we implemented the Textile Effects Restructuring Plan. In connection with this restructuring plan, during the year ended December 31, 2017, our Textile Effects segment recorded restructuring expense of approximately $6 million associated with this initiative, including $2 million for non-cancelable long-term contract termination costs and $4 million for decommissioning. During the first quarter of 2017, we implemented a restructuring program to improve competitiveness in our Textile Effects segment. In connection with this restructuring program, we recorded restructuring expense of $7 million in the year ended December 31, 2017 related primarily to workforce reductions. 2016 R estructuring A ctivities In December 2015, our Performance Products segment announced plans for a reorganization of its commercial and technical functions and a refocused divisional business strategy to better position the segment for growth in coming years. In addition, a program was launched to capture growth opportunities, improve manufacturing cost efficiency and reduce inventories. In connection with this restructuring program, we recorded restructuring expense of $16 million in 2016. All expected charges have been incurred as of the end of 2016. In connection with the Textile Effects Restructuring Plan during 2016, our Textile Effects segment recorded charges of $9 million for non-cancelable long-term contract termination costs and $20 million for decommissioning associated with this initiative.

Substantially all of our other debt, including the facilities described below, has been incurred by our subsidiaries (primarily Huntsman International); Huntsman Corporation is not a guarantor of such subsidiary debt. Certain of our subsidiaries are designated as nonguarantor subsidiaries and have third‑party debt agreements. These debt agreements contain certain restrictions with regard to dividends, distributions, loans or advances. In certain circumstances, the consent of a third party would be required prior to the transfer of any cash or assets from these subsidiaries to us. Debt Issuance Costs We record debt issuance costs related to a debt liability on the balance sheet as a reduction in the face amount of that debt liability. As of December 31, 2018 and 2017, the amount of debt issuance costs directly reducing the debt liability was $8 million and $11 million, respectively. We record the amortization of debt issuance costs as interest expense. Revolving Credit Facility On May 21, 2018, Huntsman International entered into the 2018 Revolving Credit Facility. Borrowings under the 2018 Revolving Credit Facility will bear interest at the rates specified in the credit agreement governing the 2018 Revolving Credit Facility, which will vary based on the type of loan and Huntsman International’s debt ratings. Unless earlier terminated, the 2018 Revolving Credit Facility will mature in May 2023. Huntsman International may increase the 2018 Revolving Credit Facility commitments up to an additional $500 million, subject to the satisfaction of certain conditions. In connection with entering into the 2018 Revolving Credit Facility, Huntsman International terminated all commitments and repaid all obligations under the Prior Credit Facility. In addition, we recognized a loss of early extinguishment of debt of $3 million. Upon the termination of the Prior Credit Facility, all guarantees of the obligations under the Prior Credit Facility were terminated, and all liens granted under the Prior Credit Facility were released. As of December 31, 2018, our 2018 Revolving Credit Facility was as follows (dollars in millions): Unamortized Discounts and Committed Principal Debt Issuance Carrying Facility Amount Outstanding Costs Value Interest Rate(2) Maturity 2018 Revolving Credit Facility $ 1,200 $ 50 $ — $ 50 LIBOR plus 1.75% (1) On December 31, 2018, we had an additional $9 million (U.S. dollar equivalents) of letters of credit and bank guarantees issued and outstanding under our 2018 Revolving Credit Facility. (2) Interest rates on borrowings under the 2018 Revolving Credit Facility vary based on the type of loan and Huntsman International’s debt ratings. The then applicable interest rate as of December 31, 2018 was 1.75% above LIBOR. In connection with the Demilec Acquisition on April 23, 2018, we borrowed $275 million under the Prior Credit Facility and $75 million under our U.S. A/R Program. In connection with our entry into the 2018 Revolving Credit Facility on May 21, 2018, we borrowed $275 million under the 2018 Revolving Credit Facility and repaid all obligations under our Prior Credit Facility. During 2018, we repaid an aggregate $225 million under our 2018 Revolving Credit Facility. A/R Programs Our A/R Programs are structured so that we grant a participating undivided interest in certain of our trade receivables to the U.S. SPE and the EU SPE. We retain the servicing rights and a retained interest in the securitized receivables. Information regarding our A/R Programs as of December 31, 2018 was as follows (monetary amounts in millions): Maximum Funding Amount Facility Maturity Availability(1) Outstanding Interest Rate(2) U.S. A/R Program April 2020 $ 250 $ 165 (3) Applicable rate plus 0.95% EU A/R Program April 2020 € 150 € 76 Applicable rate plus 1.30% (approximately $171) (approximately $87) (1) The amount of actual availability under our A/R Programs may be lower based on the level of eligible receivables sold, changes in the credit ratings of our customers, customer concentration levels and certain characteristics of the accounts receivable being transferred, as defined in the applicable agreements. (2) Applicable rate for our U.S. A/R Program is defined by the lender as USD LIBOR. Applicable rate for our EU A/R Program is either GBP LIBOR, USD LIBOR or EURIBOR. (3) As of December 31, 2018, we had approximately $5 million (U.S. dollar equivalents) of letters of credit issued and outstanding under our U.S. A/R Program. On April 21, 2017, we entered into amendments to our A/R Programs that, among other things, extend the scheduled termination dates to April 2020. As of December 31, 2018 and December 31, 2017, $341 million and $334 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs from continuing operations. Notes As of December 31, 2018, we had outstanding the following notes (monetary amounts in millions): Unamortized Premiums/ Discounts and Debt Notes Maturity Interest Rate Amount Outstanding Issuance Costs 2020 Senior Notes November 2020 4.875 % $650 ($648 carrying value) $ (2) 2021 Senior Notes April 2021 5.125 % €445 (€444 carrying value ($507)) — 2022 Senior Notes November 2022 5.125 % $400 ($398 carrying value) (2) 2025 Senior Notes April 2025 4.250 % €300 (€298 carrying value ($339)) (3) The 2020, 2021, 2022 and 2025 Senior Notes are general unsecured senior obligations of Huntsman International. The indentures impose certain limitations on the ability of Huntsman International and its subsidiaries to, among other things, incur additional indebtedness secured by any principal properties, incur indebtedness of nonguarantor subsidiaries, enter into sale and leaseback transactions with respect to any principal properties and consolidate or merge with or into any other person or lease, sell or transfer all or substantially all of its properties and assets. Upon the occurrence of certain change of control events, holders of the 2020, 2021, 2022 and 2025 Senior Notes will have the right to require that Huntsman International purchase all or a portion of such holder’s notes in cash at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase. Variable Interest Entity Debt As of December 31, 2018, AAC, our consolidated 50%-owned joint venture, had $86 million outstanding under its loan commitments and debt financing arrangements. As of December 31, 2018, we have $25 million classified as current debt and $61 million as long-term debt on our consolidated balance sheets. We do not guarantee these loan commitments, and AAC is not a guarantor of any of our other debt obligations. Other Debt On July 5, 2018, Huntsman Polyurethanes Shanghai, one of our majority-owned subsidiaries, made an early repayment of RMB 277 million (approximately $42 million) of term loans. Following the repayment, there are no borrowings outstanding. Note Payable from Huntsman International to Huntsman Corporation As of December 31, 2018, we have a loan of $588 million to our subsidiary, Huntsman International. The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of December 31, 2018 on our consolidated balance sheets. As of December 31, 2018, under the terms of the Intercompany Note, Huntsman International promises to pay us interest on the unpaid principal amount at a rate per annum based on the previous monthly average borrowing rate obtained under our U.S. A/R Program, less 10 basis points (provided that the rate shall not exceed an amount that is 25 basis points less than the monthly average borrowing rate obtained for the U.S. LIBOR‑based borrowings under our 2018 Revolving Credit Facility). Compliance With Covenants Our 2018 Revolving Credit Facility contains a financial covenant regarding the leverage ratio of Huntsman International and its subsidiaries. The 2018 Revolving Credit Facility also contains other customary covenants and events of default for credit facilities of this type. Upon an event of default that is not cured or waived within any applicable cure periods, in addition to other remedies that may be available to the lenders, the obligations under the 2018 Revolving Credit Facility may be accelerated. The agreements governing our A/R Programs also contain certain receivable performance metrics. Any material failure to meet the applicable A/R Programs’ metrics could lead to an early termination event under the A/R Programs, which could require us to cease our use of such facilities, prohibiting us from additional borrowings against our receivables or, at the discretion of the lenders, requiring that we repay the A/R Programs in full. An early termination event under the A/R Programs would also constitute an event of default under our 2018 Revolving Credit Facility, which could require us to pay off the balance of the 2018 Revolving Credit Facility in full and could result in the loss of our 2018 Revolving Credit Facility. We believe that we are in compliance with the covenants governing our material debt instruments, including our 2018 Revolving Credit Facility, our A/R Programs and our notes. Maturities The scheduled maturities of our debt (excluding debt to affiliates) by year as of December 31, 2018 are as follows (dollars in millions): Year ending December 31, 2019 $ 96 2020 933 2021 533 2022 402 2023 2 Thereafter 354 $ 2,320

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	12 Months Ended

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	15. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES We are exposed to market risks, such as changes in interest rates, foreign exchange rates and commodity prices. From time to time, we enter into transactions, including transactions involving derivative instruments, to manage certain of these exposures. We also hedge our net investment in certain European operations. Changes in the fair value of the hedge in the net investment of certain European operations are recorded in accumulated other comprehensive loss. In connection with the December 3, 2018 sale of Venator ordinary shares to Bank of America N.A., we recorded a forward swap. See “Note 4. Discontinued Operations and Business Dispositions” and “Note 16. Fair Value.” Interest Rate Risk Through our borrowing activities, we are exposed to interest rate risk. Such risk arises due to the structure of our debt portfolio, including the mix of fixed and floating interest rates. Actions taken to reduce interest rate risk include managing the mix and rate characteristics of various interest-bearing liabilities, as well as entering into interest rate derivative instruments. From time to time, we may purchase interest rate swaps and/or other derivative instruments to reduce the impact of changes in interest rates on our floating-rate long-term debt. Under interest rate swaps, we agree with other parties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed notional principal amount. Huntsman International had entered into several interest rate contracts to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities. These swaps were designated as cash flow hedges and the effective portion of the changes in the fair value of the swaps were recorded in other comprehensive (loss) income. These swaps expired in April 2017. During 2018, accumulated other comprehensive loss of nil was reclassified to earnings. The actual amount that will be reclassified to earnings over the next twelve months may vary from this amount due to changing market conditions. We would be exposed to credit losses in the event of nonperformance by a counterparty to our derivative financial instruments. We anticipate, however, that the counterparties will be able to fully satisfy their obligations under the contracts. Market risk arises from changes in interest rates. Foreign Exchange Rate Risk Our cash flows and earnings are subject to fluctuations due to exchange rate variation. Our revenues and expenses are denominated in various currencies. We enter into foreign currency derivative instruments to minimize the short-term impact of movements in foreign currency rates. Where practicable, we generally net multicurrency cash balances among our subsidiaries to help reduce exposure to foreign currency exchange rates. Certain other exposures may be managed from time to time through financial market transactions, principally through the purchase of spot or forward foreign exchange contracts (generally with maturities of three months or less). We do not hedge our currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of December 31, 2018 and 2017, we had approximately $151 million and $93 million, respectively, notional amount (in U.S. dollar equivalents) outstanding in foreign currency contracts with a term of approximately one month. In November 2014, we entered into two five-year cross-currency interest rate contracts and one eight-year cross-currency interest rate contract to swap an aggregate notional $200 million for an aggregate notional €161 million. The swap was designated as a hedge of net investment for financial reporting purposes. In August 2017, we terminated these cross-currency interest rate contracts and received $7 million from the counterparties. A portion of our debt is denominated in euros. We also finance certain of our non-U.S. subsidiaries with intercompany loans that are, in many cases, denominated in currencies other than the entities’ functional currency. We manage the net foreign currency exposure created by this debt through various means, including cross-currency swaps, the designation of certain intercompany loans as permanent loans because they are not expected to be repaid in the foreseeable future and the designation of certain debt and swaps as net investment hedges. Foreign currency transaction gains and losses on intercompany loans that are not designated as permanent loans are recorded in earnings. Foreign currency transaction gains and losses on intercompany loans that are designated as permanent loans are recorded in other comprehensive (loss) income. From time to time, we review such designation of intercompany loans. We review our non‑U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of December 31, 2018, we have designated approximately €510 million (approximately $581 million) of euro‑denominated debt as a hedge of our net investment. For the years ended December 31, 2018, 2017 and 2016, the amounts recognized on the hedge of our net investment were a gain of $35 million, a loss of $96 million and a gain of $27 million, respectively, and were recorded in other comprehensive (loss) income. Commodity Prices Risk Inherent in our business is exposure to price changes for several commodities. However, our exposure to changing commodity prices is somewhat limited since the majority of our raw materials are acquired at posted or market related prices, and sales prices for many of our finished products are at market related prices which are largely set on a monthly or quarterly basis in line with industry practice. Consequently, we do not generally hedge our commodity exposures.

We elected the fair value option to account for our equity method investment in Venator post deconsolidation. The fair value of our remaining investment in Venator reported in investment in unconsolidated affiliates is obtained through market observable pricing using prevailing market prices. See “Note 7. Investment in Unconsolidated Investments.” The fair values of non‑qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices. The fair value of the forward swap contract related to the sale of investment in Venator is determined based on the average of the daily volume weighted average price of Venator ordinary shares over an agreed period. The estimated fair values of our long‑term debt are based on quoted market prices for the identical liability when traded as an asset in an active market (Level 1). The fair value estimates presented herein are based on pertinent information available to management as of December 31, 2018 and 2017. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2018, and current estimates of fair value may differ significantly from the amounts presented herein.

EMPLOYEE BENEFIT PLANS
EMPLOYEE BENEFIT PLANS	17. EMPLOYEE BENEFIT PLANS Defined Benefit and Other Postretirement Benefit We provide a trusteed, non contributory defined benefit pension plan (the “Plan”) that covers the majority of our U.S. employees. Effective July 1, 2004, the Plan formula for employees not covered by a collective bargaining agreement was converted to a cash balance design. For represented employees, participation in the cash balance design was subject to the terms of negotiated contracts. For participating employees, benefits accrued under the prior formula were converted to opening cash balance accounts. The cash balance benefit formula provides annual pay credits from 6% to 12% of eligible pay, depending on age and service, plus accrued interest. The conversion to the cash balance plan did not have a significant impact on the accrued benefit liability, the funded status or ongoing pension expense. Beginning July 1, 2014, the Huntsman Defined Benefit Pension Plan was closed to new non-union entrants and as of April 1, 2015, it was closed to new union entrants. In addition, as of January 1, 2015, Rubicon LLC closed its defined benefit plan to new entrants. Following the closure of these plans, new hires have been provided with a defined contribution plan with a non-discretionary employer contribution of 6% of pay and a company match of up to 4% of pay, for a total company contribution of up to 10% of pay. We also sponsor unfunded postretirement benefit plans other than pensions, which provide medical and life insurance benefits. Effective August 1, 2015, the post retirement benefit plans were closed to new entrants. Our postretirement benefit plans provide access to two fully insured Medicare Part D plans including prescription drug benefits affected by the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Act”). We cannot determine whether the medical benefits provided by our postretirement benefit plans are actuarially equivalent to those provided by the Act. We do not collect a subsidy and our net periodic postretirement benefits cost, and related benefit obligation, do not reflect an amount associated with the subsidy. We do not subsidize the premium cost of these plans; the premiums are entirely paid by the retirees. We sponsor defined benefit plans in a number of countries outside of the U.S. The availability of these plans, and their specific design provisions, are consistent with local competitive practices and regulations. The following table sets forth the funded status of the plans for us and Huntsman International and the amounts recognized in our consolidated balance sheets at December 31, 2018 and 2017 (dollars in

Additionally, our investment strategy is to achieve returns on plan assets, subject to a prudent level of portfolio risk. Plan assets are invested in a broad range of investments. These investments are diversified in terms of domestic and international equities, both growth and value funds, including small, mid and large capitalization equities; short‑term and long‑term debt securities; real estate; and cash and cash equivalents. The investments are further diversified within each asset category. The portfolio diversification provides protection against a single investment or asset category having a disproportionate impact on the aggregate performance of the plan assets. Our pension plan assets are managed by outside investment managers. The investment managers value our plan assets using quoted market prices, other observable inputs or unobservable inputs. For certain assets, the investment managers obtain third‑party appraisals at least annually, which use valuation techniques and inputs specific to the applicable property, market, or geographic location. During 2018, there were no transfers into or out of Level 3 assets. We have established target allocations for each asset category. Our pension plan assets are periodically rebalanced based upon our target allocations. The fair value of plan assets for the pension plans was $2.5 billion and $2.7 billion at December 31, 2018 and 2017, respectively. The following plan assets are measured at fair value on a recurring basis (dollars in millions): Fair Value Amounts Using Quoted prices in active Significant other Significant December 31, markets for identical observable inputs unobservable inputs Asset category 2018 assets (Level 1) (Level 2) (Level 3) U.S. pension plans: Equities $ 382 $ 275 $ 107 $ — Fixed income 311 240 71 — Real estate/other 74 — — 74 Cash — — — — Total U.S. pension plan assets $ 767 $ 515 $ 178 $ 74 Non-U.S. pension plans: Equities $ 471 $ 161 $ 310 $ — Fixed income 747 496 251 — Real estate/other 497 93 348 56 Cash 36 36 — — Total Non-U.S. pension plan assets $ 1,751 $ 786 $ 909 $ 56 Fair Value Amounts Using Quoted prices in active Significant other Significant December 31, Markets for identical Observable inputs Unobservable inputs Asset category 2017 assets (Level 1) (Level 2) (Level 3) U.S. pension plans: Equities $ 440 $ 318 $ 122 $ — Fixed income 311 239 72 — Real estate/other 70 — — 70 Cash — — — — Total U.S. pension plan assets $ 821 $ 557 $ 194 $ 70 Non-U.S. pension plans: Equities $ 602 $ 230 $ 372 $ — Fixed income 739 477 262 — Real estate/other 508 104 349 55 Cash 34 33 1 — Total Non-U.S. pension plan assets $ 1,883 $ 844 $ 984 $ 55 The following table Real Estate/Other Year ended December 31, 2018 2017 Fair Value Measurements of Plan Assets Using Significant Unobservable Inputs (Level 3) Balance at beginning of period $ 125 $ 106 Return on pension plan assets 5 14 Purchases, sales and settlements — 5 Transfers into (out of) Level 3 — — Balance at end of period $ 130 $ 125 Based upon historical returns, the expectations of our investment committee and outside advisors, the expected long‑term rate of return on the pension assets is estimated to be between 5.68% and 7.55%.

Defined Contribution Plans—U.S. We had a money purchase pension plan that covered substantially all of our domestic employees who were hired prior to January 1, 2004. Employer contributions were made based on a percentage of employees’ earnings (ranging up to 8%). During 2014, we closed this plan to non-union participants, and in 2015, we closed this plan to union associates. We continue to provide equivalent benefits to those who were covered under this plan into their salary deferral account. We have a salary deferral plan covering substantially all U.S. employees. Plan participants may elect to make voluntary contributions to this plan up to a specified amount of their compensation. We contribute an amount equal to the participant’s contribution, not to exceed 4 % of the participant’s compensation. For new hires who are not eligible for the cash balance plan, and associates who were covered by the money purchase pension plan prior to its closure, we contribute an additional amount into their salary deferral accounts, not to exceed 6% of the participant’s compensation. Our total combined expense for the above defined contribution plans for each of the years ended December 31, 2018, 2017 and 2016 was $21 million, $22 million and $20 million, respectively. Defined Contribution Plans—Non-U.S. We have defined contribution plans in a variety of non-U.S. locations. All UK associates are eligible to participate in the Huntsman UK Pension Plan, a contract - based arrangement with a third party. Company contributions vary by business during a five-year transition period. Plan participants elect to make voluntary contributions to this plan up to a specified amount of their compensation. We contribute a matching amount not to exceed 12% of the participant’s salary for new hires and 15% of the participant’s salary for all other participants. Our total combined expense for these defined contribution plans for the years ended December 31, 2018, 2017 and 2016 was $4 million, $5 million and $4 million, respectively, primarily related to the Huntsman UK Pension Plan. Supplemental Salary Deferral Plan and Supplemental Executive Retirement Plan The Huntsman Supplemental Savings Plan (the “SSP”) is a non-qualified plan covering key management employees and allows participants to defer amounts that would otherwise be paid as compensation. The participant can defer up to 75% of their salary and bonus each year. This plan also provides benefits that would be provided under the Huntsman Salary Deferral Plan if that plan were not subject to legal limits on the amount of contributions that can be allocated to an individual in a single year. The SSP was amended and restated effective as of January 1, 2005 to allow eligible executive employees to comply with Section 409A of the Internal Revenue Code of 1986. The Huntsman Supplemental Executive Retirement Plan (the “SERP”) is an unfunded non-qualified pension plan established to provide certain executive employees with benefits that could not be provided, due to legal limitations, under the Huntsman Defined Benefit Pension Plan, a qualified defined benefit pension plan, and the Huntsman Money Purchase Pension Plan, a qualified money purchase pension plan. Assets of these plans are included in other noncurrent assets and as of December 31, 2018 and 2017 were $32 million and $33 million, respectively. During each of the years ended December 31, 2018, 2017 and 2016, we expensed a total of $1 million as contributions to the SSP and the SERP. Stock-Based Incentive Plan On May 5, 2016, our stockholders approved a new Huntsman Corporation 2016 Stock Incentive Plan (the “2016 Stock Incentive Plan”), which reserved 8.2 million shares for issuance. The Huntsman Corporation Stock Incentive Plan, as amended and restated (the “Prior Plan”), remains in effect for outstanding awards granted pursuant to the Prior Plan, but no further awards may be granted under the Prior Plan. Under the 2016 Stock Incentive Plan, we may grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, phantom stock, performance share units and other stock-based awards to our employees, directors and consultants and to employees and consultants of our subsidiaries, provided that incentive stock options may be granted solely to employees. The terms of the grants under both the 2016 Stock Incentive Plan and the Prior Plan are fixed at the grant date. As of December 31, 2018, we had approximately 9.5 million shares remaining under the 2016 Stock Incentive Plan available for grant. See “Note 22. Stock-Based Compensation Plan.” International Plans International employees are covered by various post‑employment arrangements consistent with local practices and regulations. Such obligations are included in other long‑term liabilities in our consolidated balance sheets.

The vast majority of these countries have income tax rates that are lower than the U.S. statutory rate. During 2018, the average statutory rate for countries with pre-tax income was higher than the average statutory rate for countries with pre-tax losses, resulting in a net expense of $29 million, as compared to the 21% U.S. statutory rate reflected in the reconciliation above. During 2017 and 2016, the average statutory rate for countries with pre-tax income was lower than the average statutory rate for countries with pre-tax losses, almost all of which had statutory rates lower than the U.S. of 35%, resulting in net benefits as compared to the U.S. statutory rate of $64 million and $32 million, respectively, reflected in the reconciliation above. In 2018, the $29 million net expense relates primarily to our operations in China, Germany, India and Luxembourg. In 2017, the $64 million net benefit relates primarily to our Polyurethanes business in The Netherlands, China and the U.K., as well as our Advanced Materials business in Switzerland and our Corporate function in Luxembourg. In 2016, the $32 million net benefit relates primarily to our Polyurethanes business in The Netherlands and China and our Advanced Materials business in Switzerland. In certain non-U.S. tax jurisdictions, our U.S. GAAP functional currency is different than the local tax currency. As a result, foreign exchange gains and losses will impact our effective tax rate. For 2018, 2017 and 2016, this resulted in a $10 million tax benefit, a $15 million tax expense and a $5 million tax benefit, respectively. The U.S. Tax Cuts and Jobs Act (the “U.S. Tax Reform Act”) established new tax laws that affected 2018, including, but not limited to, (1) a reduction of the U.S. federal corporate tax rate; (2) the creation of the base erosion anti-abuse tax (BEAT); (3) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (4) a new provision designed to tax global intangible low-taxed income (“GILTI”); (5) a new limitation on deductible interest expense; and (6) the repeal of the domestic production activity deduction. We have included the effects of these provisions in 2018. Our accounting for the enactment of the U.S. Tax Reform Act is complete for the year ended December 31, 2018. We recorded total tax benefit of $20 million over 2017 and 2018 related to enactment of the U.S. Tax Reform Act. As a result of the U.S. Tax Reform Act, we recorded net tax benefits of $135 million (a provisional tax benefit of $137 million in 2017 offset by a final tax expense of $2 million in 2018) due to a remeasurement of deferred U.S. tax assets and liabilities, and net tax expense of $115 million (a provisional tax expense of $85 million in 2017, a $29 million final federal tax expense in 2018 and a $1 million state tax expense in 2018) due to the transition tax on deemed repatriation of deferred foreign income. Under U.S. GAAP regarding the new GILTI tax rules, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into our measurement of deferred taxes (the “deferred method”). We have selected the “period cost method” as our accounting policy related to the new GILTI tax rules. The stated purpose of the GILTI rules is to generate additional U.S. tax related to shifting income to non-U.S. jurisdictions which incur less than a blended 13.125% non-U.S. tax rate. Our non-U.S. income is subject to a blended rate greater than 13.125% and so we would have expected no GILTI tax impact. In practice, the GILTI regulations result in additional tax liability as a result of expense allocations which limit the ability to utilize foreign tax credits against the GILTI inclusion. For 2018 we have incurred $16 million of tax expense resulting from these expense allocations. The components of income (loss) from continuing operations before income taxes were as follows (dollars in millions): Huntsman Corporation Year ended December 31, 2018 2017 2016 U.S. $ 165 $ (39) $ 91 Non-U.S. 777 686 383 Total $ 942 $ 647 $ 474 Huntsman International Year ended December 31, 2018 2017 2016 U.S. $ 147 $ (46) $ 92 Non-U.S. 777 686 383 Total $ 924 $ 640 $ 475 Components of deferred income tax assets and liabilities were as follows (dollars in millions): Huntsman Corporation December 31, 2018 2017 Deferred income tax assets: Net operating loss carryforwards $ 359 $ 411 Pension and other employee compensation 198 205 Property, plant and equipment 20 29 Intangible assets 79 88 Unrealized currency gains — 8 Other, net 45 46 Total $ 701 $ 787 Deferred income tax liabilities: Property, plant and equipment $ (363) $ (351) Pension and other employee compensation — (3) Intangible assets (34) (7) Unrealized currency losses (37) (27) Other, net (12) (31) Total $ (446) $ (419) Net deferred tax asset before valuation allowance $ 255 $ 368 Valuation allowance—net operating losses and other (227) (424) Net deferred tax asset (liability) $ 28 $ (56) Non-current deferred tax asset 324 208 Non-current deferred tax liability (296) (264) Net deferred tax asset (liability) $ 28 $ (56) Huntsman International December 31, 2018 2017 Deferred income tax assets: Net operating loss carryforwards $ 359 $ 411 Pension and other employee compensation 198 205 Property, plant and equipment 20 29 Intangible assets 79 88 Unrealized currency gains — 8 Other, net 45 46 Total $ 701 $ 787 Deferred income tax liabilities: Property, plant and equipment $ (363) $ (351) Pension and other employee compensation — (3) Intangible assets (34) (7) Unrealized currency losses (37) (27) Other, net (10) (32) Total $ (444) $ (420) Net deferred tax asset before valuation allowance $ 257 $ 367 Valuation allowance—net operating losses and other (227) (424) Net deferred tax asset (liability) $ 30 $ (57) Non-current deferred tax asset 324 208 Non-current deferred tax liability (294) (265) Net deferred tax asset (liability) $ 30 $ (57) We have gross NOLs of $1,449 million in various non‑U.S. jurisdictions. While the majority of the non‑U.S. NOLs have no expiration date, $330 million have a limited life (of which $259 million are subject to a valuation allowance) and $156 million are scheduled to expire in 2019 (of which $138 million are subject to a valuation allowance). We had $91 million of NOLs expire unused in 2018, all of which were subject to a valuation allowance. Included in the $1,449 million of gross non‑U.S. NOLs is $670 million attributable to our Luxembourg entities. As of December 31, 2018, due to the uncertainty surrounding the realization of the benefits of these losses, there is a valuation allowance of $102 million against these net tax‑effected NOLs of $174 million. We evaluate deferred tax assets to determine whether it is more likely than not that they will be realized. Valuation allowances are reviewed each period on a tax jurisdiction by jurisdiction basis to analyze whether there is sufficient positive or negative evidence to support a change in judgment about the realizability of the related deferred tax assets. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the period limits our ability to consider other subjective evidence such as our projections for the future. Our judgments regarding valuation allowances are also influenced by the costs and risks associated with any tax planning idea associated with utilizing a deferred tax asset. During 2018, we released valuation allowances of $132 million. We released significant valuation allowances on certain net deferred tax assets in Switzerland based upon the increased and sustained profitability in our Advanced Materials and Textile Effects businesses. Given Switzerland’s limited seven-year carryover of net operating losses (“NOLs”), we expect that some of our NOLs will expire unused. Therefore, we recorded a partial release of the valuation allowance of $80 million in the second quarter of 2018. In addition, based upon the separation of Venator from our U.K. combined group and the increased and sustained profitability in our Polyurethanes business in the U.K., we released significant valuation allowances on certain net deferred tax assets in the U.K. Because the U.K. places limitations on the utilization of certain NOLs and limitations on other deferred tax assets, we recorded a partial valuation allowance release of $15 million in the second quarter of 2018. We also released $24 million of significant valuation allowances on certain net deferred tax assets in Luxembourg in the third quarter of 2018 as a result of changes in estimated future taxable income resulting from increased intercompany receivables and, therefore, increased income in Luxembourg, our primary treasury center outside of the U.S. We also had miscellaneous non-significant valuation allowance releases totaling $13 million in 2018. During 2017, we released valuation allowances of $22 million. In Italy, we released valuation allowances of $7 million on certain net deferred assets of our Polyurethanes business. On March 1, 2017 and April 1, 2017, we de-merged the Italian legal entities containing our Polyurethanes business from our combined Italian tax group. The historical and expected continued profitability of those Polyurethanes businesses resulted in the release of the associated valuation allowance. In Luxembourg, we released valuation allowances of $15 million as a result of changes in estimated future taxable income resulting from increased intercompany receivables and, therefore, increased income in Luxembourg, our primary treasury center outside of the U.S. During 2016, we established valuation allowances of $12 million and released valuation allowances of $19 million. In Italy we established $9 million of valuation allowances on certain net deferred tax assets as a result of the sale of our European surfactants business, and in China we established $3 million of valuation allowances as a result of the closure of our Qingdao, China plant. We released valuation allowances of $12 million in Spain as a result of cumulative profitability and $7 million in The Netherlands as a result of tax planning to utilize losses that would have otherwise expired. Uncertainties regarding expected future income in certain jurisdictions could affect the realization of deferred tax assets in those jurisdictions and result in additional valuation allowances in future periods, or, in the case of unexpected pre-tax earnings, the release of valuation allowances in future periods. The following is a summary of changes in the valuation allowance (dollars in millions): Huntsman Corporation 2018 2017 2016 Valuation allowance as of January 1 $ 424 $ 496 $ 526 Valuation allowance as of December 31 227 424 496 Net (increase) decrease 197 72 30 Foreign currency movements 3 11 (11) (Decrease) increase to deferred tax assets with no impact on operating tax expense, including an offsetting (decrease) increase to valuation allowances (15) (11) 19 Change in valuation allowance per rate reconciliation $ 185 $ 72 $ 38 Components of change in valuation allowance affecting tax expense: Pre-tax income and losses in jurisdictions with valuation allowances resulting in no tax expense or benefit $ 53 $ 50 $ 31 Releases of valuation allowances in various jurisdictions 132 22 19 Establishments of valuation allowances in various jurisdictions — — (12) Change in valuation allowance per rate reconciliation $ 185 $ 72 $ 38 Huntsman International 2018 2017 2016 Valuation allowance as of January 1 $ 424 $ 499 $ 530 Valuation allowance as of December 31 227 424 499 Net (increase) decrease 197 75 31 Foreign currency movements 3 11 (11) (Decrease) increase to deferred tax assets with no impact on operating tax expense, including an offsetting (decrease) increase to valuation allowances (15) (14) 19 Change in valuation allowance per rate reconciliation $ 185 $ 72 $ 39 Components of change in valuation allowance affecting tax expense: Pre-tax income and losses in jurisdictions with valuation allowances resulting in no tax expense or benefit $ 53 $ 49 $ 32 Releases of valuation allowances in various jurisdictions 132 23 19 Establishments of valuation allowances in various jurisdictions — — (12) Change in valuation allowance per rate reconciliation $ 185 $ 72 $ 39 The following is a reconciliation of our unrecognized tax benefits (dollars in millions): 2018 2017 Unrecognized tax benefits as of January 1 $ 23 $ 17 Gross increases and decreases—tax positions taken during a prior period 1 3 Gross increases and decreases—tax positions taken during the current period 3 4 Decreases related to settlements of amounts due to tax authorities — — Reductions resulting from the lapse of statutes of limitation — (2) Foreign currency movements (1) 1 Unrecognized tax benefits as of December 31 $ 26 $ 23 As of December 31, 2018 and 2017, the amount of unrecognized tax benefits which, if recognized, would affect the effective tax rate is $23 million and $19 million, respectively. During 2018 we concluded and settled tax examinations in various jurisdictions including but not limited to, Egypt and the U.S. (federal and various states). During 2017, we concluded and settled tax examinations in various jurisdictions, including, but not limited to, China and the U.S. (various states). During 2016, we concluded and settled tax examinations in various non-U.S. jurisdictions including, but not limited to, China, Germany, Indonesia, The Netherlands, Spain and the U.K. During 2018 for unrecognized tax benefits that impact tax expense, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expenses (not including interest and penalty expense) of $5 million. During 2017, for unrecognized tax benefits that impact tax expense, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense (not including interest and penalty expense) of $9 million. During 2016, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense (not including interest and penalty expense) of $2 million. Additional decreases in unrecognized tax benefits were offset by cash settlements or by a decrease in net deferred tax assets and, therefore, did not affect income tax expense. In accordance with our accounting policy, we continue to recognize interest and penalties accrued related to unrecognized tax benefits in income tax expense. Year ended December 31, 2018 2017 2016 Interest expense included in tax expense $ — $ — $ 1 Penalties expense included in tax expense — — — December 31, 2018 2017 Accrued liability for interest $ 3 $ 3 Accrued liability for penalties — — We conduct business globally and, as a result, we file income tax returns in U.S. federal, various U.S. state and various non‑U.S. jurisdictions. The following table summarizes the tax years that remain subject to examination by major tax jurisdictions: Tax Jurisdiction Open Tax Years China 2009 and later Hong Kong 2015 and later Germany 2013 and later India 2004 and later Italy 2014 and later Mexico 2013 and later Switzerland 2011 and later Thailand 2012 and later The Netherlands 2015 and later United Kingdom 2017 and later United States federal 2017 and later Certain of our U.S. and non-U.S. income tax returns are currently under various stages of audit by applicable tax authorities and the amounts ultimately agreed upon in resolution of the issues raised may differ materially from the amounts accrued. We estimate that it is reasonably possible that certain of our non-U.S. unrecognized tax benefits could change within 12 months of the reporting date with a resulting decrease in the unrecognized tax benefits within a reasonably possible range of nil to $7 million. For the 12‑month period from the reporting date, we would expect that a substantial portion of the decrease in our unrecognized tax benefits would result in a corresponding benefit to our income tax expense. We have determined that our valuation allowance will not be impacted by the various aspects of the U.S. Tax Reform Act (e.g., deemed repatriation of deferred foreign income, GILTI inclusions, new categories of foreign tax credits), and therefore, we have made no related changes in any valuation allowance. Similarly, we have determined that our uncertain tax positions are not affected by the various aspects of the U.S Tax Reform Act (e.g., deemed repatriation of deferred foreign income, GILTI inclusions, new categories of foreign tax credits) and therefore, we have made no related recognition or change in any unrecognized tax positions. The U.S. Tax Reform Act includes a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. For subsidiaries with local withholding taxes, we intend to continue to invest most of these earnings indefinitely within the local country and do not expect to incur any significant, additional taxes related to such amounts.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	19. COMMITMENTS AND CONTINGENCIES Purchase Commitments We have various purchase commitments extending through 2039 for materials, supplies and services entered into in the ordinary course of business. Included in the purchase commitments table below are contracts which require minimum volume purchases that extend beyond one year or are renewable annually and have been renewed for 2018. Certain contracts allow for changes in minimum required purchase volumes in the event of a temporary or permanent shutdown of a facility. To the extent the contract requires a minimum notice period, such notice period has been included in the table below. The contractual purchase prices for substantially all of these contracts are variable based upon market prices, subject to annual negotiations. We have estimated our contractual obligations by using the terms of our current pricing for each contract. We also have a limited number of contracts which require a minimum payment even if no volume is purchased. We believe that all of our purchase obligations will be utilized in our normal operations. We made minimum payments of nil, nil and $1 million for the years ended December 31, 2018, 2017 and 2016, respectively, under such take or pay contracts without taking the product. Total purchase commitments as of December 31, 2018 are as follows (dollars in millions): Year ending December 31, 2019 $ 1,424 2020 855 2021 666 2022 629 2023 414 Thereafter 1,794 $ 5,782 Operating Leases We lease certain railcars, aircraft, equipment and facilities under long-term lease agreements. The total expense recorded under operating lease agreements in our consolidated statements of operations is approximately $76 million, $80 million and $81 million for 2018, 2017 and 2016, respectively, net of sublease rentals of approximately $2 million each for the years ended December 31, 2018, 2017 and 2016. Future minimum lease payments under operating leases as of December 31, 2018 are as follows (dollars in millions): Year ending December 31, 2019 $ 59 2020 53 2021 52 2022 49 2023 45 Thereafter 234 $ 492 Legal Matters Indemnification Matter On July 14, 2014, Deutsche Bank Securities Inc. and Credit Suisse Securities (USA) LLC demanded that we indemnify them for claims brought against them by certain other former Company stockholders in litigation filed June 14, 2014 in the United States District Court for the Eastern District of Wisconsin (the “Wisconsin Litigation”). We denied the Banks’ indemnification demand for the Wisconsin Litigation and have made no accrual with respect to this matter. The stockholders in the Wisconsin Litigation made claims for misrepresentation and conspiracy to defraud in connection with the failed acquisition by and merger with Hexion and, additionally, have named Apollo Global Management LLC and Apollo Management Holdings, L.P. as defendants. On June 30, 2016, the plaintiffs voluntarily dismissed the Apollo defendants and on December 5, 2016, the court dismissed Deutsche Bank for lack of personal jurisdiction, but denied Credit Suisse's motion to dismiss. Subsequently, Credit Suisse asked the court to reconsider its decision or certify its judgment to the Seventh Circuit Court of Appeals for an immediate appeal, which remains pending. Subsequent to discovery, Credit Suisse filed a motion for summary judgment on August 25, 2017 and a decision is pending. The court has suspended the current scheduling order, including the trial date. Other Proceedings We are a party to various other proceedings instituted by private plaintiffs, governmental authorities and others arising under provisions of applicable laws, including various environmental, products liability and other laws. Except as otherwise disclosed in this report, we do not believe that the outcome of any of these matters will have a material effect on our financial condition, results of operations or liquidity.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS
ENVIRONMENTAL, HEALTH AND SAFETY MATTERS	20. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS EHS Capital Expenditures We may incur future costs for capital improvements and general compliance under EHS laws, including costs to acquire, maintain and repair pollution control equipment. For the years ended December 31, 2018, 2017 and 2016, our capital expenditures for EHS matters totaled $44 million, $47 million and $55 million, respectively. Because capital expenditures for these matters are subject to evolving regulatory requirements and depend, in part, on the timing, promulgation and enforcement of specific requirements, our capital expenditures for EHS matters have varied significantly from year to year and we cannot provide assurance that our recent expenditures are indicative of future amounts we may spend related to EHS and other applicable laws. Environmental Reserves We have accrued liabilities relating to anticipated environmental cleanup obligations, site reclamation and closure costs and known penalties. Liabilities are recorded when potential liabilities are either known or considered probable and can be reasonably estimated. Our liability estimates are calculated using present value techniques as appropriate and are based upon requirements placed upon us by regulators, available facts, existing technology and past experience. The environmental liabilities do not include amounts recorded as asset retirement obligations. We had accrued $7 million and $21 million for environmental liabilities as of December 31, 2018 and 2017, respectively. Of these amounts, $2 million and $6 million were classified as accrued liabilities in our consolidated balance sheets as of December 31, 2018 and 2017, respectively, and $5 million and $15 million were classified as other noncurrent liabilities in our consolidated balance sheets as of December 31, 2018 and 2017, respectively. In certain cases, our remediation liabilities may be payable over periods of up to 30 years. We may incur losses for environmental remediation in excess of the amounts accrued; however, we are not able to estimate the amount or range of such potential excess. Environmental Matters Under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and similar state laws, a current or former owner or operator of real property in the U.S. may be liable for remediation costs regardless of whether the release or disposal of hazardous substances was in compliance with law at the time it occurred, and a current owner or operator may be liable regardless of whether it owned or operated the facility at the time of the release. Outside the U.S., analogous contaminated property laws, such as those in effect in France and Australia, can hold past owners and/or operators liable for remediation at former facilities. Currently, there are approximately six former facilities or third‑party sites in the U.S. for which we have been notified of potential claims against us for cleanup liabilities, including, but not limited to, sites listed under CERCLA. Based on current information and past experiences at other CERCLA sites, we do not expect these third‑party claims to have a material impact on our consolidated financial statements. Under the Resource Conservation and Recovery Act (“RCRA”) in the U.S. and similar state laws, we may be required to remediate contamination originating from our properties as a condition to our hazardous waste permit. Some of our manufacturing sites have an extended history of industrial chemical manufacturing and use, including on-site waste disposal. We are aware of soil, groundwater or surface contamination from past operations at some of our sites, and we may find contamination at other sites in the future. For example, our Port Neches, Texas, and Geismar, Louisiana, facilities are the subject of ongoing remediation requirements imposed under RCRA. Similar laws exist in a number of locations in which we currently operate, or previously operated, manufacturing facilities, such as Australia, India, France, Hungary and Italy. North Maybe Mine Remediation The North Maybe Canyon Mine site is a CERCLA site and involves a former phosphorous mine near Soda Springs, Idaho, which is believed to have been operated by several companies, including a predecessor company to us. In 2004, the U.S. Forest Service notified us that we are a CERCLA potentially responsible party (“PRP”) for contamination originating from the site. In February 2010, we and Wells Cargo (another PRP) agreed to conduct a Remedial Investigation/Feasibility Study of a portion of the site and are currently engaged in that process. At this time, we are unable to reasonably estimate our potential liabilities at this site.

HUNTSMAN CORPORATION STOCKHOLDERS’ EQUITY	21. HUNTSMAN CORPORATION STOCKHOLDERS’ EQUITY Share Repurchase Program On September 29, 2015, our Board of Directors authorized our Company to repurchase up to $150 million in shares of our common stock. Repurchases under this program may be made through open market transactions, in privately negotiated transactions, accelerated share repurchase programs or by other means. The timing and actual number of any shares repurchased depends on a variety of factors, including market conditions. The share repurchase authorization does not have an expiration date and repurchases may be commenced, suspended or discontinued from time to time without prior notice. On October 27, 2015, we entered into and funded an accelerated share repurchase agreement with Citibank, N.A. to repurchase $100 million of our common stock. Citibank, N.A. made an initial delivery of approximately 7.1 million shares of Huntsman Corporation common stock based on the closing price of $11.94 on October 27, 2015. The accelerated share repurchase agreement was completed in January 2016 with the delivery of an additional approximately 1.5 million shares of Huntsman Corporation common stock. On February 7, 2018 and on May 3, 2018, our Board of Directors authorized us to repurchase up to an additional $950 million in shares of our common stock in addition to the $50 million remaining under our September 2015 share repurchase authorization. The share repurchase program will be supported by our free cash flow generation and by the monetization of Venator shares. Repurchases may be made through the open market, including through accelerated share repurchase programs, or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. During the year ended December 31, 2018, we repurchased 10,405,457 shares of our common stock for approximately $276 million, excluding commissions, under the repurchase program. From January 1, 2019 through January 31, 2019, we repurchased an additional 537,018 shares of our common stock for approximately $11 million, excluding commissions. Dividends on Common Stock The following tables represent dividends on common stock for our Company for the years ended December 31, 2018 and 2017 (dollars in millions, except per share payment amounts): 2018 Approximate Per share amount Quarter ended payment amount paid March 31, 2018 $ 0.1625 $ 39 June 30, 2018 0.1625 39 September 30, 2018 0.1625 39 December 31, 2018 0.1625 39 2017 Approximate Per share amount Quarter ended payment amount paid March 31, 2017 $ 0.125 $ 30 June 30, 2017 0.125 30 September 30, 2017 0.125 30 December 31, 2017 0.125 30 On February 7, 2018, the Board of Directors approved an increase to the quarterly cash dividend to $0.1625 per share of common stock beginning with the March 30, 2018 quarterly dividend.

STOCK-BASED COMPENSATION PLAN
STOCK-BASED COMPENSATION PLAN	22. STOCK‑BASED COMPENSATION PLAN Under the 2016 Stock Incentive Plan, we may grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, phantom stock, performance share units and other stock-based awards to our employees, directors and consultants and to employees and consultants of our subsidiaries, provided that incentive stock options may be granted solely to employees. The terms of the grants under both the 2016 Stock Incentive Plan and the Prior Plan are fixed at the grant date. Initially, there were approximately 8.2 million shares available for issuance under the 2016 Stock Incentive Plan. However, the number of shares available for issuance may be adjusted to include any shares surrendered, exchanged, forfeited or settled in cash pursuant to the Prior Plan. As of December 31, 2018, we had approximately 9.5 million shares remaining under the 2016 Stock Incentive Plan available for grant. Option awards have a maximum contractual term of 10 years and generally must have an exercise price at least equal to the market price of our common stock on the date the option award is granted. Outstanding stock-based awards generally vest over a three‑year period. The compensation cost under the 2016 Stock Incentive Plan and the Prior Plan for our Company and Huntsman International were as follows (dollars in millions): Year ended December 31, 2018 2017 2016 Huntsman Corporation compensation cost $ 27 $ 36 $ 32 Huntsman International compensation cost 26 35 31 The total income tax benefit recognized in the statement of operations for stock-based compensation arrangements was $18 million, $18 million and $7 million for the years ended December 31, 2018, 2017 and 2016, respectively. Stock Options The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatility of our common stock through the grant date. The expected term of options granted was estimated based on the contractual term of the instruments and employees’ expected exercise and post‑vesting employment termination behavior. The risk‑free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions noted below represent the weighted averages of the assumptions utilized for all stock options granted during the year. Year ended December 31, 2018 2017 2016 Dividend yield 1.6 % 2.4 % 5.6 % Expected volatility 55.2 % 56.9 % 57.9 % Risk-free interest rate 2.6 % 2.0 % 1.4 % Expected life of stock options granted during the period 5.9 years 5.9 years 5.9 years A summary of stock option activity under the 2016 Stock Incentive Plan and the Prior Plan as of December 31, 2018 and changes during the year then ended is presented below: Weighted Weighted Average Average Remaining Aggregate Exercise Contractual Intrinsic Option Awards Shares Price Term Value (in thousands) (years) (in millions) Outstanding at January 1, 2018 7,988 $ 13.99 Granted 509 32.51 Exercised (3,873) 11.85 Forfeited (79) 18.70 Outstanding at December 31, 2018 4,545 17.81 6.5 $ 18 Exercisable at December 31, 2018 2,816 17.02 5.6 10 The weighted‑average grant‑date fair value of stock options granted during 2018, 2017 and 2016 was $15.20, $9.26 and $3.15 per option, respectively. As of December 31, 2018, there was $8 million of total unrecognized compensation cost related to nonvested stock option arrangements granted under the 2016 Stock Incentive Plan and the Prior Plan. That cost is expected to be recognized over a weighted-average period of approximately 1.8 years. During the years ended December 31, 2018, 2017 and 2016, the total intrinsic value of stock options exercised was approximately $78 million, $48 million and $1 million, respectively. Cash received from stock options exercised during the years ended December 31, 2018, 2017 and 2016 was approximately $17 million, $35 million and $1 million, respectively. The cash tax benefit from stock options exercised during the years ended December 31, 2018, 2017 and 2016 was approximately $17 million, $15 million, and nil, respectively. Nonvested Shares Nonvested shares granted under the 2016 Stock Incentive Plan and the Prior Plan consist of restricted stock and performance share unit awards, which are accounted for as equity awards, and phantom stock, which is accounted for as a liability award because it can be settled in either stock or cash. The fair value of each performance share unit award is estimated using a Monte Carlo simulation model that uses various assumptions, including an expected volatility rate and a risk-free interest rate. For the years ended December 31, 2018, 2017 and 2016, the weighted-average expected volatility rate was 44.3%. 45.0% and 39.3%, respectively, and the weighted average risk-free interest rate was 2.3%, 1.5% and 0.9%, respectively. For the performance share unit awards granted during the years ended December 31, 2018, 2017 and 2016, the number of shares earned varies based upon the Company achieving certain performance criteria over a three-year performance period. The performance criteria are total stockholder return of our common stock relative to the total stockholder return of a specified industry peer group for the three-year performance periods. A summary of the status of our nonvested shares as of December 31, 2018 and changes during the year then ended is presented below: Equity Awards Liability Awards Weighted Weighted Average Average Grant-Date Grant-Date Shares Fair Value Shares Fair Value (in thousands) (in thousands) Nonvested at January 1, 2018 2,457 $ 14.93 696 $ 14.69 Granted 435 35.04 169 32.77 Vested (840) (1) 15.67 (337) 14.70 Forfeited (129) 16.22 (24) 16.66 Nonvested at December 31, 2018 1,923 19.08 504 20.66 (1) As of December 31, 2018, a total of 358,609 restricted stock units were vested but not yet issued, of which 15,922 vested during 2018. These shares have not been reflected as vested shares in this table because, in accordance with the restricted stock unit agreements, shares of common stock are not issued for vested restricted stock units until termination of employment. As of December 31, 2018, there was $19 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the Stock Incentive Plan and the Prior Plan. That cost is expected to be recognized over a weighted-average period of approximately 1.7 years. The value of share awards that vested during the years ended December 31, 2018, 2017 and 2016 was $24 million, $22 million and $16 million, respectively.

REVENUE RECOGNITION

REVENUE RECOGNITION
REVENUE RECOGNITION	23. REVENUE RECOGNITION We generate substantially all of our revenues through sales in the open market and long‑term supply agreements. We recognize revenue when control of the promised goods is transferred to our customers. Control of goods usually passes to the customer at the time shipment is made. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. We have elected to account for all shipping and handling activities as fulfillment costs. We have also elected to expense commissions when incurred as the amortization period of the commission asset that we would have otherwise recognized is less than one year. The following table disaggregates our revenue by major source for the year ended December 31, 2018 (dollars in millions): Polyurethanes Performance Products Advanced Materials Textile Effects Eliminations Total Primary Geographic Markets(1) U.S. and Canada $ 1,700 $ 1,305 285 $ 68 $ 31 $ 3,389 Europe 1,278 423 445 135 (17) 2,264 Asia Pacific 1,236 432 301 485 (23) 2,431 Rest of world 880 195 85 136 (1) 1,295 $ 5,094 $ 2,355 $ 1,116 $ 824 $ (10) $ 9,379 Major Product Groupings MDI urethanes $ 4,525 $ 4,525 MTBE 569 569 Differentiated $ 2,120 2,120 Upstream 235 235 Specialty $ 932 932 Non-specialty 184 184 Textile chemicals and dyes and digital inks $ 824 824 Eliminations $ (10) (10) $ 5,094 $ 2,355 $ 1,116 $ 824 $ (10) $ 9,379 (a) Geographic information for revenues is based upon countries into which product is sold. Substantially all of our revenue is generated through product sales in which revenue is recognized at a point in time. At contract inception, we assess the goods and services, if any, promised in our contracts and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In substantially all cases, a contract has a single performance obligation to deliver a promised good to the customer. Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. The amount of consideration we receive and revenue we recognize is based upon the terms stated in the sales contract, which may contain variable consideration such as discounts or rebates. We allocate the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order or in the sales contract is considered the standalone selling price as it is an observable input that depicts the price as if sold to a similar customer in similar circumstances. In order to estimate the applicable variable consideration, we use historical and current trend information to estimate the amount of discounts or rebates to which customers are likely to be entitled. Historically, actual discount or rebate adjustments relative to those estimated and included when determining the transaction price have not materially differed. Payment terms vary but are generally less than one year. As our standard payment terms are less than one year, we have elected to not assess whether a contract has a significant financing component. In the normal course of business, we do not accept product returns unless the item is defective as manufactured. We establish provisions for estimated returns based on an analysis of historical experience.

OPERATING SEGMENT INFORMATION
OPERATING SEGMENT INFORMATION	26. OPERATING SEGMENT INFORMATION We derive our revenues, earnings and cash flows from the manufacture and sale of a wide variety of differentiated and commodity chemical products. We have four operating segments, which are also our reportable segments: Polyurethanes, Performance Products, Advanced Materials and Textile Effects. We have organized our business and derived our operating segments around differences in product lines. In connection with the Venator IPO in August 2017, we separated Venator and, beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations in our consolidated financial statements. On December 3, 2018, we further reduced our remaining investment in Venator by the sale of Venator ordinary shares which allowed us to deconsolidate Venator. See “Note 4. Discontinued Operations and Business Dispositions—Separation and Deconsolidation of Venator.” The major products of each reportable operating segment are as follows: Segment Products Polyurethanes MDI, PO, polyols, PG, TPU, aniline and MTBE Performance Products Amines, surfactants, LAB, maleic anhydride, other performance chemicals, EG, olefins and technology licenses Advanced Materials Basic liquid and solid epoxy resins; specialty resin compounds; cross-linking, matting and curing agents; epoxy, acrylic and polyurethane-based formulations Textile Effects Textile chemicals, dyes and digital inks Sales between segments are generally recognized at external market prices and are eliminated in consolidation. We use adjusted EBITDA to measure the financial performance of our global business units and for reporting the results of our operating segments. This measure includes all operating items relating to the businesses. The adjusted EBITDA of operating segments excludes items that principally apply to our Company as a whole. The revenues and adjusted EBITDA for each of our reportable operating segments are as follows (dollars in millions): Year ended December 31, 2018 2017 2016 Revenues: Polyurethanes $ 5,094 $ 4,399 $ 3,667 Performance Products 2,355 2,109 2,126 Advanced Materials 1,116 1,040 1,020 Textile Effects 824 776 751 Corporate and eliminations (10) 34 (46) Total $ 9,379 $ 8,358 $ 7,518 Huntsman Corporation: Segment adjusted EBITDA(1): Polyurethanes $ 946 $ 850 $ 569 Performance Products 367 296 316 Advanced Materials 225 219 223 Textile Effects 101 83 73 Corporate and other(2) (170) (189) (184) Total 1,469 1,259 997 Reconciliation of adjusted EBITDA to net income: Interest expense—continuing operations (115) (165) (203) Interest (expense) income—discontinued operations (36) (19) 1 Income tax expense—continuing operations (97) (64) (109) Income tax (expense) benefit—discontinued operations (34) (67) 24 Depreciation and amortization—continuing operations (343) (319) (318) Depreciation and amortization—discontinued operations — (68) (114) Net income attributable to noncontrolling interests 313 105 31 Other adjustments: Business acquisition and integration expenses (5) (19) (12) Purchase accounting inventory adjustments (4) — — Merger costs (2) (28) — EBITDA from discontinued operations (125) 312 81 Noncontrolling interest of discontinued operations (232) (49) (11) Fair value adjustments to Venator investment (62) — — Loss on early extinguishment of debt (3) (54) (3) Certain legal settlements and related (expenses) income (6) 11 (1) Gain on sale of assets — 9 97 Amortization of pension and postretirement actuarial losses (71) (73) (55) Plant incident remediation costs (1) (16) — U.S. Tax Reform Act impact on noncontrolling interest — 6 — Restructuring, impairment and plant closing and transition credits (costs) 4 (20) (48) Net income $ 650 $ 741 $ 357 Year ended December 31, 2018 2017 2016 Depreciation and Amortization: Polyurethanes $ 129 $ 116 $ 114 Performance Products 145 137 132 Advanced Materials 37 33 35 Textile Effects 16 14 15 Corporate and other 16 19 22 Total $ 343 $ 319 $ 318 Year ended December 31, 2018 2017 2016 Capital Expenditures: Polyurethanes $ 163 $ 162 $ 143 Performance Products 100 79 131 Advanced Materials 20 21 16 Textile Effects 20 16 19 Corporate and other 10 4 9 Total $ 313 $ 282 $ 318 December 31, 2018 2017 2016 Total Assets: Polyurethanes $ 3,427 $ 3,112 $ 2,677 Performance Products 2,088 2,069 2,046 Advanced Materials 796 796 728 Textile Effects 571 564 523 Corporate and other 1,071 823 975 Total $ 7,953 $ 7,364 $ 6,949 Year ended December 31, Huntsman International: 2018 2017 2016 Segment adjusted EBITDA(1): Polyurethanes $ 946 $ 850 $ 569 Performance Products 367 296 316 Advanced Materials 225 219 223 Textile Effects 101 83 73 Corporate and other(2) (166) (185) (180) Total 1,473 1,263 1,001 Reconciliation of adjusted EBITDA to net income: Interest expense—continuing operations (136) (181) (215) Interest (expense) income—discontinued operations (36) (19) 1 Income tax expense—continuing operations (93) (61) (108) Income tax (expense) benefit—discontinued operations (34) (67) 24 Depreciation and amortization—continuing operations (340) (311) (306) Depreciation and amortization—discontinued operations — (68) (114) Net income attributable to noncontrolling interests 313 105 31 Other adjustments: Business acquisition and integration expenses (5) (19) (12) Purchase accounting inventory adjustments (4) — — Merger costs (2) (28) — EBITDA from discontinued operations (125) 309 76 Noncontrolling interest of discontinued operations (232) (49) (11) Fair value adjustments to Venator investment (62) — — Loss on early extinguishment of debt (3) (54) (3) Certain legal settlements and related (expenses) income (6) 11 (1) Gain on sale of assets — 9 97 Amortization of pension and postretirement actuarial losses (75) (76) (58) Plant incident remediation costs (1) (16) — U.S. Tax Reform Act impact on noncontrolling interest — 6 — Restructuring, impairment and plant closing and transition credits (costs) 4 (20) (48) Net income $ 636 $ 734 $ 354 December 31, 2018 2017 2016 Depreciation and Amortization: Polyurethanes $ 129 $ 116 $ 114 Performance Products 145 137 132 Advanced Materials 37 33 35 Textile Effects 16 14 15 Corporate and other 13 11 10 Total $ 340 $ 311 $ 306 December 31, 2018 2017 2016 Capital Expenditures: Polyurethanes $ 163 $ 162 $ 143 Performance Products 100 79 131 Advanced Materials 20 21 16 Textile Effects 20 16 19 Corporate and other 10 4 9 Total $ 313 $ 282 $ 318 December 31, 2018 2017 2016 Total Assets: Polyurethanes $ 3,427 $ 3,109 $ 2,665 Performance Products 2,088 2,069 2,045 Advanced Materials 796 796 728 Textile Effects 571 564 523 Corporate and other 1,453 1,167 1,274 Total $ 8,335 $ 7,705 $ 7,235 (1) We use segment adjusted EBITDA as the measure of each segment’s profit or loss.

This loss was recorded in discontinued operations on our consolidated statements of operations. For more information see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (2) In connection with the deconsolidation of Venator, we recorded a pretax loss of $427 million during the fourth quarter of 2018 to record our remaining ownership interest in Venator at fair value. This loss was recorded in discontinued operations on our consolidated statements of operations. We elected the fair value option to account for our equity method investment in Venator post deconsolidation. Accordingly, at December 31, 2018, we recorded a pretax loss of $57 million to record our equity method investment in Venator at fair value. This loss was recorded in “Fair value adjustments to Venator investment” on our consolidated statements of operations. Furthermore, in connection with the December 3, 2018 sale of Venator shares to Bank of America N.A., we recorded a forward swap. During December 2018, we recorded a loss of $5 million in “Fair value adjustments to Venator investment” on our consolidated statements of operations to record the forward swap at fair value. For more information, see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (3) In connection with the Venator IPO in August 2017, we separated the P&A Business and, beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations on our consolidated financial statements. On December 3, 2018, we further reduced our investment in Venator by the sale of Venator ordinary shares which allowed us to deconsolidate Venator (4) Basic and diluted income per share are computed independently for each of the quarters presented based on the weighted average number of common shares outstanding during that period. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted earnings per share. (5) On December 22, 2017, the U.S. enacted the U.S. Tax Reform Act. During the fourth quarter of 2017, we and Huntsman International recorded the impact of the U.S. Tax Reform Act which resulted in a net $52 million and $53 million, respectively, income tax benefit.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
ASSET RETIREMENT OBLIGATIONS	Asset Retirement Obligations We accrue for asset retirement obligations, which consist primarily of landfill capping, closure and post‑closure costs, asbestos abatement costs, demolition and removal costs and leasehold remediation costs, in the period in which the obligations are incurred. Asset retirement obligations are accrued at estimated fair value. When the liability is initially recorded, we capitalize the cost by increasing the carrying amount of the related long‑lived asset. Over time, the liability is accreted to its estimated settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations were $11 million and $9 million at December 31, 2018 and 2017, respectively.
CARRYING VALUE OF LONG-LIVED ASSETS	Carrying Value of Long‑Lived Assets We review long‑lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Recoverability is based upon current and anticipated undiscounted cash flows, and we recognize an impairment when such estimated cash flows are less than the carrying value of the asset. Measurement of the amount of impairment, if any, is based upon the difference between carrying value and fair value. Fair value is generally estimated by discounting estimated future cash flows using a discount rate commensurate with the risks involved or selling price of assets held for sale. See “Note 12. Restructuring, Impairment and Plant Closing Costs.”
CASH AND CASH EQUIVALENTS	Cash and Cash Equivalents We consider cash in checking accounts and cash in short‑term highly liquid investments with remaining maturities of three months or less at the date of purchase, to be cash and cash equivalents. Cash flows from financing activities from discontinued operations are not presented separately in our consolidated statements of cash flows.
COST OF GOODS SOLD	Cost of Goods Sold We classify the costs of manufacturing and distributing our products as cost of goods sold. Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold.
DERIVATIVES AND HEDGING ACTIVITIES	Derivatives and Hedging Activities All derivatives, whether designated in hedging relationships or not, are recorded on our balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged items are recognized in earnings. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded in accumulated other comprehensive loss, to the extent effective, and will be recognized in the income statement when the hedged item affects earnings. Changes in the fair value of the hedge in the net investment of certain international operations are recorded in other comprehensive income (loss), to the extent effective. The effectiveness of a cash flow hedging relationship is established at the inception of the hedge, and after inception we perform effectiveness assessments at least every three months. A derivative designated as a cash flow hedge is determined to be effective if the change in value of the hedge divided by the change in value of the hedged item is within a range of 80% to 125%. Hedge ineffectiveness in a cash flow hedge occurs only if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. For a derivative that does not qualify or has not been designated as a hedge, changes in fair value are recognized in earnings.
ENVIRONMENTAL EXPENDITURES	Environmental Expenditures Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean‑up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See “Note 20.

EQUITY METHOD INVESTMENTS	Equity Method Investments We account for our equity investments where we own a non-controlling interest, but exercise significant influence, under the equity method of accounting. Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. We elected the fair value option to account for our equity method investment in Venator. For more information, see “Note 4. Discontinued Operations and Business Dispositions.” The change in the fair value related to our equity method investment in Venator is presented in “Fair value adjustments to Venator investment” on the consolidated statements of operations.
FOREIGN CURRENCY TRANSLATION	Foreign Currency Translation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss. If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three-year period), the U.S. dollar is considered to be the functional currency and gains and losses from remeasurement to the U.S. dollar from the local currency are included in the statement of operations. Where a subsidiary’s operations are effectively run, managed, financed and contracted in U.S. dollars, such as certain finance subsidiaries outside of the U.S., the U.S. dollar is considered to be the functional currency. Foreign currency transaction gains and losses are recorded in other operating (income) expense, net in our consolidated statements of operations and were gains of $3 million, $5 million and $2 million for the years ended December 31, 2018, 2017 and 2016, respectively.
INCOME TAXES	Income Taxes We use the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial and tax reporting purposes. We evaluate deferred tax assets to determine whether it is more likely than not that they will be realized. Valuation allowances are reviewed on a tax jurisdiction basis to analyze whether there is sufficient positive or negative evidence to support a change in judgment about the realizability of the related deferred tax assets for each jurisdiction. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the period limits our ability to consider other subjective evidence such as our projections for the future. Changes in expected future income in applicable jurisdictions could affect the realization of deferred tax assets in those jurisdictions. On December 22, 2017, the U.S. Tax Reform Act was signed into law. The U.S. Tax Reform Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21%, effective January 1, 2018, repealing the deduction for domestic production activities and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the U.S. Tax Reform Act, the Company recorded net tax benefits of $135 million (a provisional tax benefit of $137 million in 2017 offset by a final tax expense of $2 million in 2018) due to a remeasurement of deferred U.S. tax assets and liabilities and net tax expense of $115 million (a provisional tax expense of $85 million in 2017, a $29 million final federal tax expense in 2018 and a $1 million state tax expense in 2018) due to the transition tax on deemed repatriation of deferred foreign income. Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more‑likely‑than‑not to be realized based on the merits of the position under tax law, in order to recognize an income tax benefit. This requires us to make significant judgments regarding the merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more‑likely‑than‑not we are required to make judgments and apply assumptions to measure the amount of the tax benefits to recognize. These judgments are based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in our consolidated financial statements. We have no need for, or change in, any unrecognized tax positions due to the U.S. Tax Reform Act. For further information concerning taxes, see “Note 18. Income Taxes.”
INTANGIBLE ASSETS AND GOODWILL	Intangible Assets and Goodwill Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight‑line method over the estimated useful lives or the life of the related agreement as follows: Patents and technology 5 ‑ 30 years Trademarks 9 ‑ 30 years Licenses and other agreements 5 ‑ 15 years Other intangibles 5 ‑ 15 years Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not subject to any method of amortization, but is tested for impairment annually (at the beginning of the third quarter) and when events and circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When the fair value is less than the carrying value of the related reporting unit, we are required to reduce the amount of goodwill through a charge to earnings. Fair value is estimated using the market approach, as well as the income approach based on discounted cash flow projections. Goodwill has been assigned to reporting units for purposes of impairment testing. The following table summarizes the changes in the carrying amount of goodwill for year ended December 31, 2018 (dollars in millions): Performance Advanced Polyurethanes Products Materials Total Balance as of January 1, 2018 $ 40 $ 17 $ 83 $ 140 Goodwill acquired during year(1) 142 — — 142 Foreign currency effect on balance (9) (1) 3 (7) Balance as of December 31, 2018 $ 173 $ 16 $ 86 $ 275 (1) This reflects net amounts, including adjustments related to preliminary valuations of acquisition assets and liabilities.
INVENTORIES	Inventories Inventories are stated at the lower of cost or market, with cost determined using LIFO, first‑in first‑out, and average costs methods for different components of inventory.
LEGAL COSTS	Legal Costs We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.
NET INCOME PER SHARE ATTRIBUTABLE TO HUNTSMAN CORPORATION	Net Income Per Share Attributable to Huntsman Corporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income available to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities. Basic and diluted income per share is determined using the following information (in millions): Year ended December 31, 2018 2017 2016 Numerator: Basic and diluted income from continuing operations: Income from continuing operations attributable to Huntsman Corporation $ 764 $ 478 $ 334 Basic and diluted net income: Net income attributable to Huntsman Corporation $ 337 $ 636 $ 326 Denominator: Weighted average shares outstanding 238.1 238.4 236.3 Dilutive shares: Stock-based awards 3.5 5.5 3.3 Total weighted average shares outstanding, including dilutive shares 241.6 243.9 239.6 Additional stock‑based awards of 0.8 million, 0.8 million and 5.7 million weighted average equivalent shares of stock were outstanding during the years ended December 31, 2018, 2017 and 2016, respectively. However, these stock‑based awards were not included in the computation of diluted earnings per share for the respective periods mentioned because the effect would be anti‑dilutive.
OTHER NONCURRENT ASSETS	Other Noncurrent Assets Periodic maintenance and repairs applicable to major units of manufacturing facilities (a “turnaround”) are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround.
PRINCIPLES OF CONSOLIDATION	Principles of Consolidation Our consolidated financial statements include the accounts of our wholly owned and majority owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated.
PROPERTY, PLANT AND EQUIPMENT	Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight‑line method over the estimated useful lives or lease term as follows: Buildings and equipment 5 ‑ 50 years Plant and equipment 3 ‑ 30 years Furniture, fixtures and leasehold improvements 5 ‑ 20 years Interest expense capitalized as part of plant and equipment was $4 million, $9 million and $12 million for the years ended December 31, 2018, 2017 and 2016, respectively. Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired.
RECLASSIFICATIONS	Reclassifications Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform with the current presentation. These reclassifications include the presentation of the other components of net periodic pension cost and net periodic postretirement cost, other than service costs, within other nonoperating income in accordance with Accounting Standards Update (“ASU”) No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . We previously presented these amounts within cost of goods sold and selling, general and administrative expenses. See “—Accounting Pronouncements Adopted During 2018.” Pursuant to ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , we began including the change in restricted cash as part of the change in cash and equivalents when reconciling the beginning-of-period and end-of-period total amounts on the statements of cash flows beginning in 2018. We previously presented changes in restricted cash as an investing activity in the statements of cash flows. See “ — Accounting Pronouncements Adopted During 2018.”
REVENUE RECOGNITION	Revenue Recognition We generate substantially all of our revenue through product sales in which revenue is recognized at a point in time. We recognize revenue when control of the promised goods is transferred to our customers. Control of goods usually passes to the customer at the time shipment is made. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. See “Note 23. Revenue Recognition.”
SECURITIZATION OF ACCOUNTS RECEIVABLE	Securitization of Accounts Receivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities (“SPE”) in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in both U.S. dollars and euros. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14. Debt—Direct and Subsidiary Debt—A/R Programs.”
STOCK-BASED COMPENSATION	Stock‑Based Compensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant‑date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 22. Stock‑Based Compensation Plan.”
USE OF ESTIMATES	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
ACCOUNTING PRONOUNCEMENTS ADOPTED DURING 2018	Accounting Pronouncements Adopted During 2018 In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014‑09, Revenue from Contracts with Customers (Topic 606) , outlining a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and supersedes most current revenue recognition guidance. In March 2016, the FASB issued ASU No. 2016‑08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , clarifying the implementation guidance on principal versus agent considerations, in April 2016, the FASB issued ASU No. 2016‑10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , clarifying the implementation guidance on identifying performance obligations in a contract and determining whether an entity’s promise to grant a license provides a customer with either a right to use the entity’s intellectual property (which is satisfied at a point in time) or a right to access the entity’s intellectual property (which is satisfied over time), in May 2016, the FASB issued ASU No. 2016‑12, Revenue from Customers (Topic 606): Narrow‑Scope Improvements and Practical Expedients , providing clarifications and practical expedients for certain narrow aspects in Topic 606, and in December 2016, the FASB issued ASU 2016‑20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers . The amendments in these ASUs are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The amendments in ASU No. 2014‑09, ASU No. 2016‑08, ASU No. 2016‑10, ASU No. 2016‑12 and ASU No. 2016‑20 should be applied retrospectively. On January 1, 2018, we adopted the amendments in ASU No. 2014‑09, ASU No. 2016‑08, ASU No. 2016‑10, ASU No. 2016‑12 and ASU No. 2016‑20 to all current revenue contracts using the modified retrospective approach, and the initial adoption of these amendments did not have an impact on our consolidated financial statements. As a result of the adoption of these amendments, we revised our accounting policy for revenue recognition as detailed in “Note 23. Revenue Recognition.” In January 2016, the FASB issued ASU No. 2016‑01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities . The amendments in this ASU require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. On January 1, 2018, we adopted the amendments in ASU No. 2016‑01 and upon transition recorded a cumulative-effect adjustment of approximately $10 million, net of tax, relating to prior years’ changes in fair value of equity investments from other comprehensive income to retained earnings. Beginning in the first quarter of 2018, we also started recognizing the current period change in fair value of equity investments in net income. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The amendments in this ASU clarify and include specific guidance to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The amendments in this ASU should be applied using a retrospective transition method to each period presented. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016‑18, Statement of Cash Flows (Topic 230): Restricted Cash . The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning‑of‑period and end‑of‑period total amounts shown on the statement of cash flows. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, and interim period within those fiscal years. The amendments in this ASU were applied using a retrospective transition method to each period presented. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of the amendments in this ASU did not have a significant impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017‑01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. We adopted the amendments in this ASU effective January 1, 2018, and the initial adoption of this ASU did not have a significant impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The amendments in this ASU require that an employer report the service cost component of net periodic pension cost and net periodic postretirement benefit cost in the same line items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside of income from operations. The amendments in this ASU also allow only the service cost component to be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit cost in assets. We adopted the amendments in this ASU effective January 1, 2018, which impacted the presentation of our consolidated financial statements. Our previous presentation of service cost components was consistent with the amendments in this ASU. However, we now present the other components within other income, net, whereas we previously presented these within cost of goods sold and selling, general and administrative expenses. In August 2018, the FASB issued ASU No. 2018‑13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this ASU modify certain disclosure requirements on fair value measurements in Topic 820 to improve the effectiveness of such disclosures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We early adopted the removed and modified disclosures in this ASU for the year ended December 31, 2018, and they did not have a significant impact on our consolidated financial statements. We elected to delay the adoption of the additional disclosures in this ASU until their effective date, but do not expect the adoption of the additional disclosures in this ASU to have a significant impact on our consolidated financial statements. Accounting Pronouncements Pending Adoption in Future Periods In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The amendments in this ASU will increase transparency and comparability among entities by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this ASU will require lessees to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 , providing an optional transition practical expedient to not evaluate under Topic 842 existing or expired land easements that were not previously accounted for as leases under the current leases guidance in Topic 840, and in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements , providing an optional transition method allowing entities to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The amendments in these ASUs are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early application of the amendments in these ASUs is permitted for all entities. Reporting entities can elect to recognize and measure leases under these amendments at the beginning of the earliest period presented using a modified retrospective approach or otherwise elect the transition method provided under ASU No. 2018-11. We are currently evaluating the impact of the adoption of the amendments in these ASUs on our consolidated financial statements. Based on our preliminary assessment the estimated right-of-use asset and lease liability that we will recognize on our balance sheet upon adoption will be approximately $400 million to $450 million. This estimate could change pending the finalization of the incremental borrowing rate for certain leases. We are evaluating key policy elections and considerations under the amendments in these ASUs and are developing internal policies to address these amendments. In August 2017, the FASB issued ASU No. 2017‑12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships as well as the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements to increase the understandability of the results of an entity’s intended hedging strategies. The amendments in this ASU also include certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted in any interim period after the issuance of this ASU. Transition requirements and elections should be applied to hedging relationships existing on the date of adoption. For cash flow and net investment hedges, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness, and the amended presentation and disclosure guidance is required only prospectively. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018‑14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans . The amendments in this ASU modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing disclosures that no longer are considered cost beneficial, clarifying the specific requirements of disclosures and adding disclosure requirements identified as relevant. The amendments in this ASU are effective for fiscal years ending after December 15, 2020 and should be applied on a retrospective basis to all periods presented. Early adoption is permitted. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018‑15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in any interim period after the issuance of this ASU. We do not expect the adoption of the amendments in this ASU to have a significant impact on our consolidated financial statements. In August 2018, the SEC issued a final rule, SEC Final Rule Release No. 33-10532, Disclosure Update and Simplification , that amends certain of its disclosure requirements that have become redundant, duplicative, overlapping, outdated or superseded, in light of other SEC disclosure requirements or U.S. GAAP. For filings on Form 10-Q, the final rule, amongst other items, extends to interim periods the annual requirement to disclose changes in stockholders’ equity. As amended by the final rule, registrants must now analyze changes in stockholders’ equity, in the form of a reconciliation, for the then current and comparative year-to-date interim periods, with subtotals for each interim period. The final rule became effective on November 5, 2018, that date being 30 days after its publication in the Federal Register. As such, we will apply these changes in the presentation of stockholders’ equity beginning with our March 31, 2019 Form 10-Q.

This loss was recorded in discontinued operations on our consolidated statements of operations. For more information see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (2) In connection with the deconsolidation of Venator, we recorded a pretax loss of $427 million during the fourth quarter of 2018 to record our remaining ownership interest in Venator at fair value. This loss was recorded in discontinued operations on our consolidated statements of operations. We elected the fair value option to account for our equity method investment in Venator post deconsolidation. Accordingly, at December 31, 2018, we recorded a pretax loss of $57 million to record our equity method investment in Venator at fair value. This loss was recorded in “Fair value adjustments to Venator investment” on our consolidated statements of operations. Furthermore, in connection with the December 3, 2018 sale of Venator shares to Bank of America N.A., we recorded a forward swap. During December 2018, we recorded a loss of $5 million in “Fair value adjustments to Venator investment” on our consolidated statements of operations to record the forward swap at fair value. For more information, see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (3) In connection with the Venator IPO in August 2017, we separated the P&A Business and, beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations on our consolidated financial statements. On December 3, 2018, we further reduced our investment in Venator by the sale of Venator ordinary shares which allowed us to deconsolidate Venator beginning in December 2018. See “Note 4. Discontinued Operations and Business Dispositions—Separation of Venator.” (4) Basic and diluted income per share are computed independently for each of the quarters presented based on the weighted average number of common shares outstanding during that period. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted earnings per share. (5) On December 22, 2017, the U.S. enacted the U.S. Tax Reform Act. During the fourth quarter of 2017, we and Huntsman International recorded the impact of the U.S. Tax Reform Act which resulted in a net $52 million and $53 million, respectively, income tax benefit.

This loss was recorded in discontinued operations on our consolidated statements of operations. For more information see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (2) In connection with the deconsolidation of Venator, we recorded a pretax loss of $427 million during the fourth quarter of 2018 to record our remaining ownership interest in Venator at fair value. This loss was recorded in discontinued operations on our consolidated statements of operations. We elected the fair value option to account for our equity method investment in Venator post deconsolidation. Accordingly, at December 31, 2018, we recorded a pretax loss of $57 million to record our equity method investment in Venator at fair value. This loss was recorded in “Fair value adjustments to Venator investment” on our consolidated statements of operations. Furthermore, in connection with the December 3, 2018 sale of Venator shares to Bank of America N.A., we recorded a forward swap. During December 2018, we recorded a loss of $5 million in “Fair value adjustments to Venator investment” on our consolidated statements of operations to record the forward swap at fair value. For more information, see “Note 4. Discontinued Operations and Dispositions – Separation and Deconsolidation of Venator.” (3) In connection with the Venator IPO in August 2017, we separated the P&A Business and, beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations on our consolidated financial statements. On December 3, 2018, we further reduced our investment in Venator by the sale of Venator ordinary shares which allowed us to deconsolidate Venator (4) Basic and diluted income per share are computed independently for each of the quarters presented based on the weighted average number of common shares outstanding during that period. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted earnings per share. (5) On December 22, 2017, the U.S. enacted the U.S. Tax Reform Act. During the fourth quarter of 2017, we and Huntsman International recorded the impact of the U.S. Tax Reform Act which resulted in a net $52 million and $53 million, respectively, income tax benefit.
