GENERAL	1. GENERAL ​ Certain Definitions ​ For convenience in this report, the terms “Company,” “Huntsman,” “our,” “us” or “we” may be used to refer to Huntsman Corporation and, unless the context otherwise requires, its subsidiaries and predecessors. In this report, “Huntsman International” refers to Huntsman International LLC (our wholly-owned subsidiary). ​ 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. ​ Interim Financial Statements ​ Our unaudited interim condensed consolidated financial statements and Huntsman International’s unaudited interim condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “U.S. GAAP”) and in management’s opinion reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of results of operations, comprehensive income, financial position and cash flows for the periods presented. Results for interim periods are not necessarily indicative of those to be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2018 for our Company and Huntsman International. ​ D escription of Business ​ We are a global manufacturer of differentiated organic chemical products. 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 dyes 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. ​ We operate in four segments: Polyurethanes, Performance Products, Advanced Materials and Textile Effects. In August 2017, we separated our Titanium Dioxide and Performance Additives business (the “P&A Business”) through an initial public offering (“IPO”) of ordinary shares of Venator Materials PLC (“Venator”), formerly a wholly-owned subsidiary. Beginning in the third quarter of 2017, we reported the results of operations of Venator as discontinued operations. On December 3, 2018, we sold an additional 4% of Venator ordinary shares which allowed us to immediately deconsolidate Venator and account for our remaining ownership interest in Venator as an equity method investment using the fair value option. For more information, see “Note 4. Business Dispositions—Separation and Deconsolidation of Venator.” In a series of transactions beginning in 2006, we sold or shut down substantially all of our Australian styrenics operations and our North American polymers and base chemicals operations. We also report the results of operations of these businesses as discontinued operations. ​ C ompany ​ Our Company, a Delaware corporation, was formed in 2004 to hold the Huntsman businesses. Jon M. Huntsman founded the predecessor to our Company in 1970 as a small packaging company. Since then, we have grown through a series of significant acquisitions and now own a global portfolio of businesses. ​ Currently, we operate all of our businesses through Huntsman International, our wholly-owned subsidiary. Huntsman International is a Delaware limited liability company and was formed in 1999. ​ Huntsman Corporation and Huntsman International Financial Statements ​ Except where otherwise indicated, these notes relate to the condensed consolidated financial statements for both our Company and Huntsman International. The differences between our financial statements and Huntsman International’s 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. ​ Principles of Consolidation ​ Our condensed 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. Intercompany accounts and transactions have been eliminated. ​ Recent Developments ​ Acquisition of Remaining 50% Interest in Sasol-Huntsman Joint Venture ​ On July 26, 2019, we announced that we signed a definitive agreement with Sasol, our joint venture partner, to acquire the remaining 50% interest that we do not own in the Sasol-Huntsman maleic anhydride joint venture. The joint venture owns a manufacturing facility in Moers, Germany with capacity to produce 230 million pounds of maleic anhydride. We will pay $92.5 million for the remaining interest in the joint venture, adjusted for net debt and other agreed upon adjustments, funded from our available liquidity. We anticipate the closing of this transaction to occur in the fourth quarter of 2019, subject to regulatory approvals and customary closing conditions. ​ Use of Estimates ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities 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. ​

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS ​ Accounting Pronouncements Adopted During 2019 ​ In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 Leases (Topic 842): Targeted Improvements ASUs using the transition method that allowed us to initially apply the new lease standard at the adoption date. The initial adoption of the new lease standard had a material impact on our condensed consolidated balance sheets, but did not have an impact on our condensed consolidated statements of operations. The most significant impact was the recognition of operating lease liabilities and operating lease right-of-use assets. On January 1, 2019, we recognized operating lease liabilities of $495 million and operating lease right-of-use assets of $466 million. As a result of the adoption of these amendments, we revised our accounting policy for leases as detailed in “Note 7. Leases.” ​ In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ​ In August 2018, the SEC issued a final rule, SEC Final Rule Release No. 33-10532, Disclosure Update and Simplification ​ Accounting Pronouncements Pending Adoption in Future Periods ​ 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 ​ 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 ​

BUSINESS COMBINATION	3. BUSINESS COMBINATION ​ On April 23, 2018, we acquired 100% of the outstanding equity interests of Demilec (USA) Inc. and Demilec Inc. (collectively, “Demilec”) for approximately $353 million, including working capital adjustments, in an all-cash transaction (“Demilec Acquisition”), which was funded from our previous $650 million senior secured revolving credit facility (the “Prior Credit Facility”) and our U.S. accounts receivable securitization program (“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 $1 million for the six months ended June 30, 2018. 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. ​ ​ ​ ​ ​ ​ Fair value of assets acquired and liabilities assumed: ​ ​ ​ Cash paid for the 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 ​ ​ 140 Accounts payable ​ ​ (16) Accrued liabilities ​ ​ (3) Deferred income taxes ​ ​ (22) Other noncurrent liabilities ​ ​ — Total fair value of net assets acquired ​ $ 353 ​ As a result of a preliminary valuation of the assets and liabilities, reallocations were made during 2018 in certain property, plant and equipment, intangible asset, goodwill and deferred tax balances. As a result of the finalization of the valuation of the assets and liabilities, additional reallocations were made in 2019 in certain goodwill, other noncurrent liabilities and deferred tax balances. Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, all of which are being amortized over 15 years. We have assigned any excess of the acquisition cost of the fair values to goodwill. During the third quarter of 2018, we received $4 million related to the settlement of certain purchase price adjustments. The goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets, and synergies. ​ If this acquisition were to have occurred on January 1, 2018, 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) ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ June 30, 2018 ​ June 30, 2018 Revenues ​ $ 2,418 ​ $ 4,757 Net income ​ ​ 623 ​ ​ 962 Net income attributable to Huntsman Corporation ​ ​ 414 ​ ​ 677 ​ ​ ​ ​ ​ ​ ​ Income per share: ​ ​ ​ ​ ​ ​ Basic ​ ​ 1.73 ​ ​ 2.82 Diluted ​ ​ 1.71 ​ ​ 2.77 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pro Forma (Unaudited) ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ June 30, 2018 ​ June 30, 2018 Revenues ​ $ 2,418 ​ $ 4,754 Net income ​ ​ 620 ​ ​ 956 Net income attributable to Huntsman International ​ ​ 411 ​ ​ 671 ​

BUSINESS DISPOSITIONS
BUSINESS DISPOSITIONS	4. BUSINESS DISPOSITIONS ​ 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. ​ 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 determined based on the average of the daily volume weighted average price of Venator ordinary shares over an agreed period (the “Forward Swap”). Over this agreed period, we received aggregate proceeds of $19 million, $16 million of which was received in the first quarter of 2019. Following this transaction, we retained approximately 49% ownership in Venator and this transaction allowed us to deconsolidate Venator beginning in December 2018, and thus we began accounting for our remaining interest in Venator as an equity method investment and elected the fair value option to account for our equity method investment in Venator. ​ Although we intend to monetize our remaining 49% ownership in Venator, our ability to sell our ordinary shares of Venator at a reasonable price is dependent upon the prevailing market value of Venator common stock. The depressed Venator stock price inhibits our ability to sell our remaining shares of Venator at a reasonable price, which could continue for more than twelve months. Therefore, in December 2018, our equity method investment in Venator did not meet the held for sale criteria and our equity method investment in Venator was recorded in continuing operations. ​ During the first quarter of 2019, we recorded a gain of $1 million to record the Forward Swap at fair value. Accordingly, for the three and six months ended June 30, 2019, we recorded a loss of $18 million and a gain of $57 million, respectively, to record our investment in Venator at fair value. These gains and losses were recorded in “Fair value adjustments to Venator investment” on our condensed consolidated statements of operations. ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ Six months ​ ended ​ ended ​ June 30, 2018 ​ June 30, 2018 Major classes of line items constituting pretax income of discontinued operations: ​ ​ ​ ​ ​ Trade sales, services and fees, net $ 630 ​ $ 1,257 Cost of goods sold ​ 118 ​ ​ 594 Other expense items, net that are not major ​ 94 ​ ​ 111 Income from discontinued operations before income taxes ​ 418 ​ ​ 552 Income tax expense ​ (84) ​ ​ (104) Income from discontinued operations, net of tax ​ 334 ​ ​ 448 Net income attributable to noncontrolling interests ​ (2) ​ ​ (4) Net income attributable to discontinued operations $ 332 ​ $ 444 ​

VARIABLE INTEREST ENTITIES	6. 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. ​ ● Arabian Amines Company 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 Arabian Amines Company’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 at the time of the last reconsideration event, we took on a disproportionate amount of risk of loss due to a related-party loan to Sasol-Huntsman for which we assumed the default risk. On July 26, 2019, we announced that we signed a definitive agreement with Sasol to acquire the remaining 50% interest that we do not own in the Sasol-Huntsman maleic anhydride joint venture. See “Note 1. General—Recent Developments.” ​ Creditors of these entities have no recourse to our general credit. See “Note 8. Debt—Direct and Subsidiary Debt.” As the primary beneficiary of these variable interest entities at June 30, 2019, the joint ventures’ assets, liabilities and results of operations are included in our condensed consolidated financial statements. ​ The following table summarizes the carrying amount of our variable interest entities’ assets and liabilities included in our condensed consolidated balance sheet as of June 30, 2019 and our consolidated balance sheet as of December 31, 2018 (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2019 2018 Current assets ​ $ 92 ​ $ 92 Property, plant and equipment, net ​ ​ 263 ​ ​ 265 Operating lease right-of-use assets ​ ​ 19 ​ ​ — Other noncurrent assets ​ ​ 152 ​ ​ 136 Deferred income taxes ​ ​ 32 ​ ​ 32 Intangible assets ​ ​ 10 ​ ​ 10 Goodwill ​ ​ 13 ​ ​ 14 Total assets ​ $ 581 ​ $ 549 Current liabilities ​ $ 162 ​ $ 178 Long-term debt ​ ​ 45 ​ ​ 61 Deferred income taxes ​ ​ 11 ​ ​ 11 Noncurrent operating lease liabilities ​ ​ 14 ​ ​ — Other noncurrent liabilities ​ ​ 95 ​ ​ 97 Total liabilities ​ $ 327 ​ $ 347 ​ The revenues, income from continuing operations before income taxes and net cash provided by operating activities for our variable interest entities for the three and six months ended June 30, 2019 and 2018 are as follows (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ ​ June 30, ​ June 30, ​ ​ 2019 2018 ​ 2019 2018 Revenues ​ $ 31 ​ $ 39 ​ $ 67 ​ $ 77 Income from continuing operations before income taxes ​ ​ 4 ​ ​ 9 ​ ​ 13 ​ ​ 19 Net cash provided by operating activities ​ ​ 29 ​ ​ 14 ​ ​ 60 ​ ​ 29 ​

LEASES
LEASES	7. LEASES ​ On January 1, 2019, we adopted the new lease standard using the optional transition method provided under ASU 2018-11, which allowed us to initially apply the amendments of the new lease standard at the adoption date. Upon adoption of the new lease standard, we elected the package of three practical expedients permitted under the transition guidance within the new lease standard, which among other things, allowed us to carry forward the historical lease classification on existing leases at adoption. In addition, we elected the practical expedient related to land easements, which allowed us to carry forward our accounting treatment for land easements on existing agreements. We also elected the hindsight practical expedient to determine the lease term for existing leases. ​ The determination of whether a contract is or contains a lease is performed at the lease inception date. Lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term, using incremental borrowing rates as the implicit rates are not readily determinable for our leases. The incremental borrowing rates are determined on a collateralized basis and vary from lease to lease depending on the country where the leased asset exists and the term of the lease arrangement. We combine lease components with non-lease components and account for them as a single lease component for all classes of underlying assets, except for leases of manufacturing and research facilities and administrative offices. For these assets, non-lease components are separated from lease components and accounted for as normal operating expenses. ​ We primarily lease manufacturing and research facilities, administrative offices, land, tanks, railcars and equipment. Leases with an initial term of 12 months or less are not recognized on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Our variable lease cost was nil for the both the three and six months ended June 30, 2019. Our leases have remaining lives from one month to 38 years. Certain lease agreements include one or more options to renew, at our discretion, with renewal terms that can extend the lease term by approximately one year to 30 years or more. Renewal and termination options that we are reasonably certain to exercise have been included in the calculation of the lease right-of-use assets and lease liabilities. None of our lease agreements contain material residual value guarantees or material restrictions or covenants. ​ The components of operating lease expense, cash flows and supplemental noncash information are as follows (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ ​ June 30, 2019 ​ June 30, 2019 Operating lease expense: ​ ​ ​ ​ ​ ​ Cost of goods sold ​ $ 16 ​ $ 32 Selling, general and administrative ​ ​ 4 ​ ​ 8 Research and development ​ ​ 2 ​ ​ 3 Total operating lease expense(1) ​ $ 22 ​ $ 43 ​ ​ ​ ​ ​ ​ ​ Cash paid for amounts included in the measurement of lease liabilities: ​ ​ ​ ​ ​ ​ Operating cash flows from operating leases ​ $ 18 ​ $ 35 ​ ​ ​ ​ ​ ​ ​ Supplemental noncash information: ​ ​ ​ ​ ​ ​ Leased assets obtained in exchange for new operating lease liabilities ​ $ 5 ​ $ 472 (1) Total operating lease expense includes short-term lease expense of approximately $1 million for each of the three and six months ended June 30, 2019. ​ The weighted-average lease term and discount rate for our operating leases are as follows: ​ ​ ​ Weighted-average remaining lease term 10 years Weighted-average discount rate 4.3% ​ The undiscounted cash flows of operating lease liabilities as of June 30, 2019 are as follows (dollars in millions): ​ ​ ​ ​ Year ending December 31, ​ ​ 2019 (excluding the six months ended June 30, 2019) $ 39 2020 ​ 73 2021 ​ 68 2022 ​ 60 2023 ​ 55 Thereafter ​ 293 Total lease payments ​ 588 Less imputed interest ​ (109) Total $ 479 ​ 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 ​ As of June 30, 2019, we have additional leases, primarily for leases of manufacturing facilities, that have not yet commenced of approximately $45 million.

DEBT ​ Outstanding debt, net of debt issuance costs, consisted of the following (dollars in millions): ​ Huntsman Corporation ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2019 ​ 2018 Senior Credit Facilities: ​ ​ ​ ​ ​ Revolving facility ​ $ 185 ​ $ 50 Amounts outstanding under A/R programs ​ ​ 236 ​ ​ 252 Senior notes ​ ​ 1,977 ​ ​ 1,892 Variable interest entities ​ ​ 81 ​ ​ 86 Other ​ ​ 26 ​ ​ 40 Total debt ​ $ 2,505 ​ $ 2,320 Total current portion of debt ​ $ 228 ​ $ 96 Long-term portion of debt ​ ​ 2,277 ​ ​ 2,224 Total debt ​ $ 2,505 ​ $ 2,320 ​ Huntsman International ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2019 ​ 2018 Senior Credit Facilities: ​ ​ ​ ​ ​ ​ Revolving facility ​ $ 185 ​ $ 50 Amounts outstanding under A/R programs ​ ​ 236 ​ ​ 252 Senior notes ​ ​ 1,977 ​ ​ 1,892 Variable interest entities ​ ​ 81 ​ ​ 86 Other ​ ​ 26 ​ ​ 40 Total debt, excluding debt to affiliates ​ $ 2,505 ​ $ 2,320 Total current portion of debt ​ $ 228 ​ $ 96 Long-term portion of debt ​ ​ 2,277 ​ ​ 2,224 Total debt, excluding debt to affiliates ​ $ 2,505 ​ $ 2,320 Notes payable to affiliates-current ​ ​ 100 ​ ​ 100 Notes payable to affiliates-noncurrent ​ ​ 373 ​ ​ 488 Total debt ​ $ 2,978 ​ $ 2,908 ​ Direct and Subsidiary Debt ​ ​ Certain of our subsidiaries have third-party debt agreements that 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 to the face amount of that debt liability. As of June 30, 2019 and December 31, 2018, the amount of debt issuance costs directly reducing the debt liability was $12 million and $8 million, respectively. We record the amortization of debt issuance costs as interest expense. ​ Revolving Credit Facility ​ On May 21, 2018, Huntsman International entered into a new $1.2 billion senior unsecured revolving credit facility (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 on 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 June 30, 2019, 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 ​ $ 185 (1) $ — (1) $ 185 (1) USD LIBOR plus 1.50% ​ 2023 (1) On June 30, 2019, we had an additional $8 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 June 30, 2019 was 1.50% above LIBOR. ​ A/R Programs ​ Our U.S. A/R Program and our European accounts receivable securitization program (“EU A/R Program” and collectively with the U.S. A/R Program, “A/R Programs”) are structured so that we transfer certain of our trade receivables to the U.S. special purpose entity (“U.S. SPE”) and the European special purpose entity (“EU SPE”) in transactions intended to be true sales or true contributions. The receivables collateralize debt incurred by the U.S. SPE and the EU SPE. Information regarding our A/R Programs as of June 30, 2019 was as follows (monetary amounts in millions): ​ On April 18, 2019, we entered into amendments to the EU A/R Program (the “European Amendment”) and the U.S. A/R Program (the “U.S. Amendment”). The European Amendment, among other things, extended the scheduled commitment termination date of the loan facility to April 2022, reduced the facility maximum funding availability from €150 million to €100 million and made certain other amendments. The U.S. Amendment, among other things, extended the scheduled commitment termination date of the loan facility to April 2022 and made certain other amendments. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Maximum Funding Amount ​ Facility Maturity Availability(1) Outstanding Interest Rate(2) U.S. A/R Program April 2022 ​ $ 250 ​ $ 150 (3) Applicable rate plus 0.90% EU A/R Program April 2022 ​ € 100 ​ € 76 Applicable rate plus 1.30% ​ ​ ​ ​ ​ (or approximately $114) ​ ​ (or approximately $86) ​ ​ (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) The 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 June 30, 2019, we had approximately $5 million (U.S. dollar equivalents) of letters of credit issued and outstanding under our U.S. A/R Program. ​ As of June 30, 2019 and December 31, 2018, $372 million and $341 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs. ​ Notes ​ On March 13, 2019, Huntsman International completed a $750 million offering of its 4.50% senior notes due 2029 (“2029 Senior Notes”). On March 27, 2019, Huntsman International applied the net proceeds of the offering of the 2029 Senior Notes to redeem in full $650 million in aggregate principal amount of its 4.875% senior notes due 2020 (“2020 Senior Notes”) and also paid associated costs and accrued interest of $21 million and $12 million, respectively. In addition, we recognized a loss on early extinguishment of debt of $23 million. The 2029 Senior Notes bear interest at 4.50% per year, payable semi-annually on May 1 and November 1, and will mature on May 1, 2029. Huntsman International may redeem the 2029 Senior Notes in whole or in part at any time prior to February 1, 2029 at a price equal to 100% of the principal amount thereof plus a “make-whole” premium and accrued and unpaid interest. Huntsman International may redeem the 2029 Senior Notes at any time, in whole or from time to time in part, on or after February 1, 2029 at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest. Note Payable from Huntsman International to Huntsman Corporation ​ As of June 30, 2019, we had a loan of $473 million to our subsidiary, Huntsman International (the “Intercompany Note”). The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of June 30, 2019 on our condensed consolidated balance sheets. As of June 30, 2019, 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 contained in the agreements governing our material debt instruments, including our 2018 Revolving Credit Facility, our A/R Programs and our notes.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	6 Months Ended
	Jun. 30, 2019
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	9. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ​ We are exposed to market risks, such as changes in interest rates, foreign exchange rates and commodity pricing risks. 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 as an unrealized currency translation adjustment in accumulated other comprehensive loss. ​ All derivatives, whether designated as 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. To the extent applicable, we perform effectiveness assessments in order to use hedge accounting at each reporting period. For a derivative that does not qualify as a hedge, changes in fair value are recognized in earnings. ​ Our revenues and expenses are denominated in various foreign currencies, and our cash flows and earnings are thus subject to fluctuations due to exchange rate variations. From time to time, we may 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 one year or less). We do not hedge our foreign currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of June 30, 2019, we had approximately $191 million in notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts. ​ 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 exposures. 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. On January 9, 2019, we entered into a six-year $17 million notional value interest rate hedge with a fixed rate of 2.66%. This swap is designated as a cash flow hedge and the effective portion of the changes in the fair value of the swap is recorded in other comprehensive income. The fair value of this hedge on June 30, 2019 was approximately $1 million and was recorded in other noncurrent liabilities on our condensed consolidated balance sheet. ​ 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 income on our condensed consolidated statements of comprehensive 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 June 30, 2019, we have designated approximately €475 million (approximately $540 million) of euro-denominated debt as a hedge of our net investment. For the six months ended June 30, 2019 and 2018, the amount recognized on the hedge of our net investment was a gain of $3 million ​ In connection with the December 3, 2018 sale of Venator ordinary shares to Bank of America N.A., we recorded a forward swap. In February 2019, we settled this forward swap and received $16 million from the counterparty. See “Note 4. Business Dispositions” and “Note 10. Fair Value.”

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 4. Business Dispositions.” The fair values of non-qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices. 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 June 30, 2019 and December 31, 2018. 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 June 30, 2019, and current estimates of fair value may differ significantly from the amounts presented herein. ​ The following assets and liabilities are measured at fair value on a recurring basis (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Amounts Using ​ ​ ​ ​ ​ Quoted prices ​ Significant other ​ Significant ​ ​ ​ ​ ​ in active markets ​ observable ​ unobservable ​ ​ June 30, ​ for identical ​ inputs ​ inputs Description 2019 assets (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-qualified employee benefit plan investments ​ $ 24 ​ $ 24 ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate contracts ​ $ (1) ​ $ — ​ $ (1) ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Amounts Using ​ ​ ​ ​ ​ Quoted prices ​ Significant other ​ Significant ​ ​ ​ ​ ​ in active markets ​ observable ​ unobservable ​ ​ December 31, ​ for identical ​ inputs ​ inputs Description 2018 assets (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-qualified employee benefit plan investments ​ $ 23 ​ $ 23 ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward swap contract related to the sale of investment in Venator(1) ​ ​ 14 ​ ​ — ​ ​ 14 ​ ​ — ​ ​ $ 37 ​ $ 23 ​ $ 14 ​ $ — (1) In connection with the December 3, 2018 sale of Venator ordinary shares to Bank of America N.A., we recorded a forward swap.

REVENUE RECOGNITION
REVENUE RECOGNITION	11. 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.

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.

COMMITMENTS AND CONTINGENCIES	15. COMMITMENTS AND CONTINGENCIES ​ Legal Matters ​ Indemnification Matters ​ On July 14, 2014, Deutsche Bank Securities Inc. and Credit Suisse Securities (USA) LLC (the “Banks”) 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, 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	16. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS ​ EHS Capital Expenditures ​ We may incur future costs for capital improvements and general compliance under environmental, health and safety (“EHS”) laws, including costs to acquire, maintain and repair pollution control equipment. For the six months ended June 30, 2019 and 2018, our capital expenditures for EHS matters totaled $22 million and $15 million. 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 for environmental liabilities for both June 30, 2019 and December 31, 2018. Of these amounts, $2 million was classified as accrued liabilities in our condensed consolidated balance sheets for both June 30, 2019 and December 31, 2018, and $5 million was classified as other noncurrent liabilities in our condensed consolidated balance sheets for both June 30, 2019 and December 31, 2018. 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 nine 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 condensed 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. ​

STOCK-BASED COMPENSATION PLANS

STOCK-BASED COMPENSATION PLANS	6 Months Ended

STOCK-BASED COMPENSATION PLANS	17. STOCK-BASED COMPENSATION PLANS ​ 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. 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 June 30, 2019, we had approximately 8 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 annually over a three-year period. ​ The compensation cost from continuing operations under the 2016 Stock Incentive Plan and the Prior Plan for our Company and Huntsman International were as follows (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ ​ June 30, ​ June 30, ​ 2019 ​ 2018 ​ 2019 ​ 2018 Huntsman Corporation compensation cost $ 7 ​ $ 7 ​ $ 15 ​ $ 15 Huntsman International compensation cost ​ ​ 7 ​ ​ 7 ​ ​ 14 ​ ​ 14 ​ The total income tax benefit recognized in the condensed consolidated statements of operations for us and Huntsman International for stock-based compensation arrangements was $2 million and $15 million for the six months ended June 30, 2019 and 2018, 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 average of the assumptions utilized for stock options granted during the periods. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six months ​ ​ ended ​ ​ June 30, ​ ​ 2019 ​ 2018 Dividend yield ​ 2.9 % ​ 1.5 % Expected volatility ​ 54.0 % ​ 55.2 % Risk-free interest rate ​ 2.5 % ​ 2.6 % Expected life of stock options granted during the period ​ 5.9 years ​ 5.9 years ​ During each of the three months ended June 30, 2019 and 2018, no stock options were granted. ​ A summary of stock option activity under the 2016 Stock Incentive Plan and the Prior Plan as of June 30, 2019 and changes during the six months 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, 2019 ​ 4,545 ​ $ 17.81 ​ ​ ​ ​ ​ ​ Granted ​ ​ 896 ​ ​ 22.66 ​ ​ ​ ​ ​ ​ Exercised ​ ​ (167) ​ ​ 10.50 ​ ​ ​ ​ ​ ​ Forfeited ​ ​ (41) ​ ​ 25.42 ​ ​ ​ ​ ​ ​ Outstanding at June 30, 2019 ​ ​ 5,233 ​ ​ 18.81 ​ ​ 6.6 ​ $ 18 Exercisable at June 30, 2019 ​ ​ 3,786 ​ ​ 16.62 ​ ​ 5.6 ​ ​ 18 ​ The weighted-average grant-date fair value of stock options granted during the six months ended June 30, 2019 was $9.27 per option. As of June 30, 2019, there was $12 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 2.1 years. ​ The total intrinsic value of stock options exercised during the six months ended June 30, 2019 and 2018 was approximately $2 million and $73 million, respectively. Cash received from stock options exercised during the six months ended June 30, 2019 and 2018 was approximately $1 million and $15 million, respectively. The cash tax benefit from stock options exercised during the six months ended June 30, 2019 and 2018 was approximately nil and $16 million, 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 six months ended June 30, 2019 and 2018, the weighted-average expected volatility rate was 34.6% and 44.3% , respectively, and the weighted average risk-free interest rate was 2.5% and 2.3% , respectively. For the performance share unit awards granted in the six months ended June 30, 2019 and 2018, 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 June 30, 2019 and changes during the six months 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, 2019 ​ ​ 1,923 ​ $ 19.08 ​ ​ 504 ​ $ 20.66 Granted ​ ​ 702 ​ ​ 24.64 ​ ​ 256 ​ ​ 22.64 Vested ​ ​ (959) (1)(2) ​ 13.53 ​ ​ (310) ​ ​ 16.31 Forfeited ​ ​ (16) ​ ​ 26.15 ​ ​ (12) ​ ​ 25.19 Nonvested at June 30, 2019 ​ ​ 1,650 ​ ​ 24.61 ​ ​ 438 ​ ​ 24.76 (1) As of June 30, 2019, a total of 389,095 restricted stock units were vested but not yet issued, of which 30,486 vested during the six months ended June 30, 2019. 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. ​ (2) A total of 412,246 performance share unit awards are reflected in the vested shares in this table, which represents the target number of performance share unit awards for this grant and were included in the balance at December 31, 2018. During the six months ended June 30, 2019, an additional 357,006 performance share unit awards with a grant date fair value of $10.22 vested above the target in accordance the performance criteria of these awards. As of June 30, 2019, there was $30 million of total unrecognized compensation cost related to nonvested share compensation 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 2.1 years. The value of share awards that vested during the six months ended June 30, 2019 and 2018 was $24 million each.

INCOME TAXES

INCOME TAXES	6 Months Ended

INCOME TAXES	18. 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 an individual 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. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of our businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the applicable 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. ​ ​ During the six months ended June 30, 2019, we recognized a discrete tax benefit of $4 million related to excess tax benefits from share-based compensation. ​ The $58 million of gains on fair value adjustments to our Venator investment, recorded as part of non-operating income from continuing operations, is not subject to tax under The Netherlands’ statutory participation exemption. As a significant, unusual, non-operating item, it was treated discretely and excluded from the annual effective tax rate calculation for interim reporting. ​ Huntsman Corporation ​ We recorded income tax expense from continuing operations of $102 million and $57 million for the six months ended June 30, 2019 and 2018, respectively. Our tax expense is significantly affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions. Our effective tax rate was 29% for the six months ended June 30, 2019. The non-cash tax expense related to the change in tax rate in Switzerland, partially offset by the non-taxed income from fair value adjustments to our Venator investment, resulted in a higher effective tax rate through the first six months of 2019. ​ Huntsman International ​ Huntsman International recorded income tax expense from continuing operations of $100 million and $55 million for the six months ended June 30, 2019 and 2018, respectively. Our tax expense is significantly affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions. Our effective tax rate was 29% for the six months ended June 30, 2019. The non-cash tax expense related to the change in tax rate in Switzerland, partially offset by the non-taxed income from fair value adjustments to our Venator investment, resulted in a higher effective tax rate through the first six months of 2019. ​

NET INCOME PER SHARE	19. NET INCOME PER SHARE ​ 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): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ Six months ​ ​ ended ​ ended ​ ​ June 30, ​ June 30, ​ 2019 2018 2019 2018 Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted income from continuing operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income from continuing operations attributable to Huntsman Corporation ​ $ 112 ​ $ 268 ​ $ 230 ​ $ 483 Basic and diluted net income: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income attributable to Huntsman Corporation $ 110 ​ $ 414 ​ $ 229 ​ $ 688 Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 230.6 ​ ​ 238.7 ​ ​ 231.9 ​ ​ 239.8 Dilutive shares: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stock-based awards ​ ​ 1.5 ​ ​ 4.0 ​ ​ 1.7 ​ ​ 4.4 Total weighted average shares outstanding, including dilutive shares ​ ​ 232.1 ​ ​ 242.7 ​ ​ 233.6 ​ ​ 244.2 ​ Additional stock-based awards of 3.8 million and 0.6 million weighted average equivalent shares of stock were outstanding during the three months ended June 30, 2019 and 2018, respectively, and 3.5 million and 0.8 million weighted average equivalent shares of stock were outstanding during the six months ended June 30, 2019 and 2018, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the three and six months ended June 30, 2019 and 2018 because the effect would be anti-dilutive.

OPERATING SEGMENT INFORMATION	20. 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 condensed 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 and account for our remaining investment in Venator as an equity method investment using the fair value option post deconsolidation. See “Note 4. 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. Adjusted EBITDA is presented as a measure of the financial performance of our global business units and for reporting the results of our operating segments.
