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, 2019 for our Company and Huntsman International. ​ Description of Businesses ​ 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, durable and non-durable consumer products, digital inks, electronics, insulation 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, maleic anhydride, epoxy-based polymer formulations, textile chemicals and dyes. ​ We currently 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, which was repaid in full during the quarter ended March 31, 2020. ​ 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. ​ Reclassifications ​ Prior periods have been recasted to record the results of operations of our chemical intermediates businesses, which includes PO/MTBE, and our surfactants businesses (collectively, our “Chemical Intermediates Businesses”) as discontinued operations. See “Note 4. Discontinued Operations and Business Dispositions—Sale of Chemical Intermediates Businesses.” ​ Recent Developments ​ Sale of Chemical Intermediates Businesses On January 3, 2020, we completed the sale of our Chemical Intermediates Businesses to Indorama Ventures Holdings L.P. (“Indorama”) in a transaction valued at approximately $2 billion, comprising a cash purchase price of approximately $1.93 billion, which includes estimated adjustments to the purchase price for working capital, plus the transfer of approximately $72 million in net underfunded pension and other post-employment benefit liabilities. See “Note 4. Discontinued Operations and Business Dispositions—Sale of Chemical Intermediates Businesses.” ​ Acquisition of Icynene-Lapolla ​ Acquisition of CVC Thermoset Specialties ​ ​ 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. ​

Intangible assets acquired included in this preliminary allocation consist primarily of trademarks, trade secrets and customer relationships. The applicable amortization periods are still being assessed. For purposes of this preliminary allocation of fair value, we have assigned any excess of the acquisition cost over the estimated preliminary fair value to goodwill. The estimated goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets, and synergies. We expect that none of the estimated goodwill arising from the acquisition will be deductible for income tax purposes. It is possible that material changes to this preliminary purchase price allocation could occur. ​ The acquired business had revenues and net loss of $27 million and $6 million, respectively, for the period from the date of acquisition to March 31, 2020. ​ If this acquisition were to have occurred on January 1, 2019, the following estimated pro forma revenues, net income, net income attributable to Huntsman Corporation and Huntsman International would have been reported (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ Pro Forma (Unaudited) ​ Three months ​ ended March 31, ​ 2020 ​ 2019 Revenues $ 1,623 ​ $ 1,725 Net income ​ 704 ​ ​ 129 Net income attributable to Huntsman Corporation ​ 701 ​ ​ 117 ​ ​ ​ ​ ​ ​ ​ ​ Pro Forma (Unaudited) ​ Three months ​ ended March 31, ​ 2020 ​ 2019 Revenues $ 1,623 ​ $ 1,725 Net income ​ 703 ​ ​ 126 Net income attributable to Huntsman International ​ 700 ​ ​ 114 ​ ​

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. ​ ● Arabian Amines Company is our 50% -owned joint venture with Zamil group that manufactures products for our Performance Products segment. ​ During the first quarter of 2020, there were no changes in our variable interest entities. ​ Sasol-Huntsman was our 50%-owned joint venture with Sasol that owned and operated a maleic anhydride facility in Moers, Germany. On September 30, 2019, we acquired the 50% noncontrolling interest that we did not own in Sasol-Huntsman. As such, as of September 30, 2019, Sasol-Huntsman was no longer accounted for as a variable interest entity. ​ Creditors of these entities have no recourse to our general credit. See “Note 7. Debt—Direct and Subsidiary Debt.” As the primary beneficiary of these variable interest entities at March 31, 2020, 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 March 31, 2020 and our consolidated balance sheet as of December 31, 2019 (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2020 2019 Current assets ​ $ 55 ​ $ 50 Property, plant and equipment, net ​ ​ 178 ​ ​ 180 Operating lease right-of-use assets ​ ​ 17 ​ ​ 16 Other noncurrent assets ​ ​ 139 ​ ​ 132 Deferred income taxes ​ ​ 30 ​ ​ 30 Total assets ​ $ 419 ​ $ 408 Current liabilities ​ $ 159 ​ $ 151 Long-term debt ​ ​ 26 ​ ​ 29 Noncurrent operating lease liabilities ​ ​ 12 ​ ​ 11 Other noncurrent liabilities ​ ​ 85 ​ ​ 87 Total liabilities ​ $ 282 ​ $ 278 ​ The revenues, income from continuing operations before income taxes and net cash provided by operating activities for our variable interest entities for the three months ended March 31, 2020 and 2019 are as follows (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ ​ ended ​ ​ March 31, ​ ​ 2020(1) 2019 Revenues ​ $ — ​ $ 36 Income from continuing operations before income taxes ​ ​ 1 ​ ​ 9 Net cash provided by operating activities ​ ​ 6 ​ ​ 31 (1) As of September 30, 2019, Sasol-Huntsman was no longer accounted for as a variable interest entity.

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 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. For both March 31, 2020 and December 31, 2019, the amount of debt issuance costs directly reducing the debt liability was $11 million. We record the amortization of debt issuance costs as interest expense. ​ Revolving Credit Facility ​ As of March 31, 2020, our $1.2 billion senior unsecured revolving credit facility (“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 ​ $ — (1) $ — (1) $ — (1) USD LIBOR plus 1.50% ​ 2023 (1) On March 31, 2020, we had an additional $7 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 March 31, 2020 was 1.50% above LIBOR. ​ Term Loan Credit Facility ​ On September 24, 2019, Huntsman International entered into a 364-day ​ A/R Programs ​ Our U.S. accounts receivable securitization program (“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. ​ In December 2019, we entered into amendments to our EU A/R program (the “European Amendment”) and our U.S. A/R Program (the “U.S. Amendment”). The European Amendment allowed the removal of pledged obligors related to the Chemical Intermediates Businesses sold to Indorama. The U.S. Amendment allowed the removal of pledged obligors related to the Chemical Intermediates Businesses sold to Indorama as well as reduced the maximum funding capacity from $250 million to $150 million upon completion of the sale on January 3, 2020. ​ Information regarding our A/R Programs as of March 31, 2020 was as follows (monetary amounts in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Maximum Funding Amount ​ Facility Maturity Availability(1) Outstanding Interest Rate(2) U.S. A/R Program April 2022 ​ $ 150 ​ $ — (3) Applicable rate plus 0.90% EU A/R Program April 2022 ​ € 100 ​ € 50 Applicable rate plus 1.30% ​ ​ ​ ​ ​ (or approximately $110) ​ ​ (or approximately $55) ​ ​ (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. The applicable rate for our EU A/R Program is either GBP LIBOR, USD LIBOR or EURIBOR. ​ (3) As of March 31, 2020, 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 March 31, 2020 and December 31, 2019, $252 million and $221 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 in the first quarter of 2019. 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 ​ During the quarter ended March 31, 2020, our loan of $380 million to our subsidiary Huntsman International was repaid to us in full. ​ Compliance with Covenants ​ 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 2019 Term Loan, our A/R Programs and our notes.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	8. 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. ​ 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 March 31, 2020, we had approximately $173 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 was designated as a cash flow hedge and the effective portion of the changes in the fair value of the swap was recorded in other comprehensive income. In November 2019, we terminated this swap and paid $1 million to our counterparties. ​ We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of March 31, 2020, we have designated approximately €465 million (approximately $511 million) of euro-denominated debt as a hedge of our net investment. For both the three months ended March 31, 2020 and March 31, 2019, the amount recognized on the hedge of our net investment was a gain of $8 million and was recorded in other comprehensive income in our condensed consolidated statements of comprehensive income. ​ 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. Discontinued Operations and Business Dispositions—Separation and Deconsolidation of Venator.” The fair values of our non-qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices (Level 1).

REVENUE RECOGNITION
REVENUE RECOGNITION	10. 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 tables disaggregate our revenue from continuing operations by major source for the three months ended March 31, 2020 (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Polyurethanes ​ Performance Products ​ Advanced Materials ​ Textile Effects ​ Corporate and Eliminations ​ Total Primary Geographic Markets(1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. and Canada $ 370 ​ $ 129 ​ $ 63 ​ $ 17 ​ $ (7) ​ $ 572 Europe ​ 245 ​ ​ 74 ​ ​ 101 ​ ​ 32 ​ ​ (1) ​ ​ 451 Asia Pacific ​ 199 ​ ​ 70 ​ ​ 56 ​ ​ 103 ​ ​ — ​ ​ 428 Rest of world ​ 74 ​ ​ 19 ​ ​ 21 ​ ​ 28 ​ ​ — ​ ​ 142 ​ $ 888 ​ $ 292 ​ $ 241 ​ $ 180 ​ $ (8) ​ $ 1,593 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Major Product Groupings ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ MDI urethanes $ 888 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 888 Differentiated ​ ​ ​ $ 292 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 292 Specialty ​ ​ ​ ​ ​ ​ $ 211 ​ ​ ​ ​ ​ ​ ​ ​ 211 Non-specialty ​ ​ ​ ​ ​ ​ ​ 30 ​ ​ ​ ​ ​ ​ ​ ​ 30 Textile chemicals, dyes and digital inks ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 180 ​ ​ ​ ​ ​ 180 Eliminations ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ (8) ​ ​ (8) ​ $ 888 ​ $ 292 ​ $ 241 ​ $ 180 ​ $ (8) ​ $ 1,593 (1) Geographic information for revenues is based upon countries into which product is sold. ​ The following tables disaggregate our revenue from continuing operations by major source for the three months ended March 31, 2019 (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Polyurethanes ​ Performance Products ​ Advanced Materials ​ Textile Effects ​ Corporate and Eliminations ​ Total Primary Geographic Markets(1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. and Canada $ 336 ​ $ 135 ​ $ 73 ​ $ 17 ​ $ (19) ​ $ 542 Europe ​ 270 ​ ​ 93 ​ ​ 121 ​ ​ 34 ​ ​ 2 ​ ​ 520 Asia Pacific ​ 237 ​ ​ 56 ​ ​ 61 ​ ​ 105 ​ ​ — ​ ​ 459 Rest of world ​ 81 ​ ​ 16 ​ ​ 17 ​ ​ 33 ​ ​ 1 ​ ​ 148 ​ $ 924 ​ $ 300 ​ $ 272 ​ $ 189 ​ $ (16) ​ $ 1,669 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Major Product Groupings ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ MDI urethanes $ 924 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 924 Differentiated ​ ​ ​ $ 300 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 300 Specialty ​ ​ ​ ​ ​ ​ $ 230 ​ ​ ​ ​ ​ ​ ​ ​ 230 Non-specialty ​ ​ ​ ​ ​ ​ ​ 42 ​ ​ ​ ​ ​ ​ ​ ​ 42 Textile chemicals, dyes and digital inks ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 189 ​ ​ ​ ​ ​ 189 Eliminations ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ (16) ​ ​ (16) ​ $ 924 ​ $ 300 ​ $ 272 ​ $ 189 ​ $ (16) ​ $ 1,669 (1) 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.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS	15. 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 three months ended March 31, 2020 and 2019, our capital expenditures for EHS matters totaled $6 million and $7 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 $4 million for environmental liabilities as of both March 31, 2020 and December 31, 2019. Of these amounts, $1 million was classified as accrued liabilities in our condensed consolidated balance sheets as of both March 31, 2020 and December 31, 2019, and $3 million was classified as other noncurrent liabilities in our condensed consolidated balance sheets as of both March 31, 2020 and December 31, 2019. 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 Canyon 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. During the first quarter of 2020, there have been no significant developments, and, at this time, we are unable to reasonably estimate our potential liabilities at this site. ​

STOCK-BASED COMPENSATION PLANS
STOCK-BASED COMPENSATION PLANS	16. STOCK-BASED COMPENSATION PLANS ​ As of March 31, 2020, we had approximately 7 million shares remaining under the stock-based compensation plans 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 stock-based compensation plans for our Company and Huntsman International were as follows (dollars in millions): ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ ended ​ March 31, ​ 2020 ​ 2019 Huntsman Corporation compensation cost $ 7 ​ $ 8 Huntsman International compensation cost ​ 6 ​ ​ 7 ​ The total income tax benefit recognized in the condensed consolidated statements of operations for us and Huntsman International for stock-based compensation arrangements was $1 million and $5 million for the three months ended March 31, 2020 2019 ​ 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. ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ 2020 ​ 2019 Dividend yield 3.0 % ​ 2.9 % Expected volatility 53.1 % ​ 54.0 % Risk-free interest rate 1.5 % ​ 2.5 % Expected life of stock options granted during the period 5.9 years ​ 5.9 years ​ A summary of stock option activity under the stock-based compensation plans as of March 31, 2020 and changes during the three 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, 2020 ​ 5,025 ​ $ 19.08 ​ ​ ​ ​ ​ ​ Granted ​ ​ 750 ​ ​ 21.54 ​ ​ ​ ​ ​ ​ Exercised ​ ​ (154) ​ ​ 12.55 ​ ​ ​ ​ ​ ​ Forfeited ​ ​ (8) ​ ​ 26.33 ​ ​ ​ ​ ​ ​ Outstanding at March 31, 2020 ​ ​ 5,613 ​ ​ 19.57 ​ ​ 6.4 ​ $ 7 Exercisable at March 31, 2020 ​ ​ 4,141 ​ ​ 18.31 ​ ​ 5.4 ​ ​ 7 ​ The weighted-average grant-date fair value of stock options granted during the three months ended March 31, 2020 was $8.27 per option. As of March 31, 2020, there was $12 million of total unrecognized compensation cost related to nonvested stock option arrangements granted under the stock-based compensation plans. That cost is expected to be recognized over a weighted-average period of approximately 2.2 years. ​ The total intrinsic value of stock options exercised during each of the three months ended March 31, 2020 and 2019 was approximately $1 million, respectively. Cash received from stock options exercised during the three months ended March 31, 2020 and 2019 was approximately nil and $1 million, respectively. The cash tax benefit from stock options exercised during each of the three months ended March 31, 2020 and 2019 was approximately nil. ​ Nonvested Shares ​ Nonvested shares granted under the stock-based compensation plans 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 three months ended March 31, 2020 and 2019, the weighted-average expected volatility rate was 34.0% and 34.6%, respectively, and the weighted average risk-free interest rate was 1.4% and 2.5%, respectively. For the performance share unit awards granted in the three months ended March 31, 2020 and 2019, 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 March 31, 2020 and changes during the three 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, 2020 ​ ​ 1,640 ​ $ 24.61 ​ ​ 427 ​ $ 24.80 Granted ​ ​ 822 ​ ​ 21.97 ​ ​ 237 ​ ​ 21.54 Vested ​ ​ (561) (1)(2) ​ 25.21 ​ ​ (216) ​ ​ 24.66 Forfeited ​ ​ (2) ​ ​ 25.26 ​ ​ (4) ​ ​ 25.63 Nonvested at March 31, 2020 ​ ​ 1,899 ​ ​ 23.29 ​ ​ 444 ​ ​ 23.12 (1) As of March 31, 2020, a total of 422,755 restricted stock units were vested but not yet issued, of which 33,660 vested during the three months ended March 31, 2020.

INCOME TAXES
INCOME TAXES	17. 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. ​ ​ assets ​ Huntsman Corporation ​ We recorded income tax expense from continuing operations of $7 million and $45 million for the three months ended March 31, 2020 and 2019, 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. The decrease in pretax income, as well as the one-time reduction in our Switzerland net deferred tax assets related to the 2019 tax rate change, resulted in lower income tax expense during the first quarter of 2020 as compared to the same period of 2019. ​ Huntsman International ​ Huntsman International recorded income tax expense from continuing operations of $7 million and $44 million for the three months ended March 31, 2020 and 2019, 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. The decrease in pretax income, as well as the one-time reduction in our Switzerland net deferred tax assets related to the 2019 tax rate change, resulted in lower income tax expense during the first quarter of 2020 as compared to the same period of 2019. ​

NET INCOME PER SHARE	18. 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 (loss) per share is determined using the following information (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ​ ​ ​ ended ​ ​ ​ March 31, ​ ​ 2020 2019 Numerator: ​ ​ ​ ​ ​ ​ ​ Basic and diluted (loss) income from continuing operations: ​ ​ ​ ​ ​ ​ ​ (Loss) income from continuing operations attributable to Huntsman Corporation ​ $ (72) ​ $ 96 ​ Basic and diluted net income: ​ ​ ​ ​ ​ ​ ​ Net income attributable to Huntsman Corporation $ 705 ​ $ 119 ​ Denominator: ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 223.2 ​ ​ 233.1 ​ Dilutive shares: ​ ​ ​ ​ ​ ​ ​ Stock-based awards ​ ​ — ​ ​ 2.0 ​ Total weighted average shares outstanding, including dilutive shares ​ ​ 223.2 ​ ​ 235.1 ​ ​ Additional stock-based awards of 5.6 million and 3.1 million weighted average equivalent shares of stock were outstanding during the three months ended March 31, 2020 and 2019, respectively.

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. Beginning in the third quarter of 2019, we reported the results of our Chemical Intermediates Businesses as discontinued operations in our condensed consolidated financial statements for all periods presented. See “Note 4. Discontinued Operations and Business Dispositions—Sale of Chemical Intermediates Businesses.” ​ The major products of each reportable operating segment are as follows: ​ ​ ​ ​ Segment Products Polyurethanes ​ MDI, polyols, PG, TPU and aniline Performance Products ​ Specialty amines, ethyleneamines, maleic anhydride 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.
