Certain information set forth in this report contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements other than historical factual information are forward-looking statements, including without limitation statements regarding: projections of revenue, expenses, profit, profit margins, tax rates, tax provisions, cash flows, pension and benefit obligations and funding requirements, our liquidity position or other projected financial measures; projected impact of COVID-19 on our operations and future financial results; management’s plans and strategies for future operations, including statements relating to anticipated operating performance, cost reductions, restructuring activities, new product and service developments, competitive strengths or market position, acquisitions, divestitures, business separations, spin-offs, or other distributions, strategic opportunities, securities offerings, stock repurchases, dividends and executive compensation; growth, declines and other trends in markets we sell into; new or modified laws, regulations and accounting pronouncements; outstanding claims, legal proceedings, tax audits and assessments and other contingent liabilities; foreign currency exchange rates and fluctuations in those rates; general economic and capital markets conditions; the timing of any of the foregoing; assumptions underlying any of the foregoing; and any other statements that address events or developments that we intend or believe will or may occur in the future. In some cases, forward-looking statements can be identified by terminology such as “believes,” “expects,” “may,” “will,” “should,” “anticipates” or “intends” or the negative of such terms or other comparable terminology, or by discussions of strategy. We may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.

All forward-looking statements, including without limitation any projections derived from management’s examination of historical operating trends, are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management’s expectations, beliefs and projections will be achieved. All forward-looking statements apply only as of the date made. We undertake no obligation to publicly update or revise forward-looking statements whether because of new information, future events or otherwise, except as required by securities and other applicable law.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this report. Any forward-looking statements should be considered in light of the risks set forth in “Part II. Item 1A. Risk Factors” below and “Part I. Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020.

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 (loss), 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, 2020 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, 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 operate 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; and

● the different capital structures.

​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 

Amendments to Accounts Receivable Securitization Programs

On July 1, 2021, we entered into amendments to 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”) that, among other things, extended the scheduled termination dates of our A/R Programs from April 2022 to July 2024. For additional information, see “Note 8. Debt—Direct and Subsidiary Debt—A/R Programs.”

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.

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS 

Accounting Pronouncements ADopted During 2021

We adopted the following accounting pronouncement during 2021, which did not have a significant impact on our condensed consolidated financial statements: 

● Financial Accounting Standards Board Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848): Scope.

3. BUSINESS COMBINATIONS AND ACQUISITIONS

Acquisition of gaBRIEL Performance Products

On January 15, 2021, we completed the acquisition of Gabriel Performance Products, a North American specialty chemical manufacturer of specialty additives and epoxy curing agents for the coatings, adhesives, sealants and composite end-markets (“Gabriel Acquisition”), from funds affiliated with Audax Private Equity in an all-cash transaction of approximately $251 million, subject to customary closing adjustments. The purchase price was funded from available liquidity, and the acquired business is being integrated into our Advanced Materials segment. Transaction costs related to this acquisition were approximately nil and $2 million, respectively, for the three and nine months ended September 30, 2021 and were recorded in other operating income, net in our condensed consolidated statements of operations.

We accounted for the Gabriel Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The preliminary allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the Gabriel Acquisition	$	251
Cash	$	9
Accounts receivable		13
Inventories		26
Property, plant and equipment		23
Intangible assets		16
Goodwill		174
Accounts payable		(7	)
Accrued liabilities		(2	)
Deferred income taxes		(1	)
Total fair value of net assets acquired	$	251

18

The acquisition cost allocation is preliminary pending final determination of the fair value of assets acquired and liabilities assumed, including final valuation of certain liabilities, property, plant and equipment, intangible assets, leases and deferred taxes. Intangible assets acquired included in this preliminary allocation consist primarily of trademarks, technology and trade secrets. 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 in our Advanced Materials specialty portfolio and synergies. We expect that a portion of the estimated goodwill arising from the acquisition will be deductible for income tax purposes, but the amount is still being assessed. It is possible that material changes to this preliminary allocation of acquisition cost could occur.

The acquired business had revenues and net income of $81 million and $14 million, respectively, for the period from the date of acquisition to September 30, 2021.

Acquisition of CVC Thermoset Specialties

On May 18, 2020, we completed our acquisition of CVC Thermoset Specialties, a North American specialty chemical manufacturer serving the industrial composites, adhesives and coatings markets (“CVC Thermoset Specialties Acquisition”). We acquired the business for $304 million from Emerald Performance Materials LLC, which is majority owned by affiliates of American Securities LLC, in an all-cash transaction funded from available liquidity. The acquired business was integrated into our Advanced Materials segment. 

We accounted for the CVC Thermoset Specialties Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the CVC Thermoset Specialties Acquisition	$	304
Accounts receivable	$	12
Inventories		37
Property, plant and equipment		67
Intangible assets		117
Goodwill		120
Accounts payable		(7	)
Accrued liabilities		(1	)
Deferred income taxes		(41	)
Total fair value of net assets acquired	$	304

Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, which are predominantly being amortized over a period of 20 years. The goodwill recognized is attributable primarily to projected future profitable growth in our Advanced Materials specialty portfolio and synergies. None of the goodwill arising from the acquisition is deductible for income tax purposes. 

19

Acquisition of Icynene-Lapolla

On February 20, 2020, we completed our acquisition of Icynene-Lapolla, a leading North American manufacturer and distributor of spray polyurethane foam insulation systems for residential and commercial applications (“Icynene-Lapolla Acquisition”). We acquired the business from an affiliate of FFL Partners, LLC for $353 million in an all-cash transaction funded from available liquidity. The acquired business was integrated into our Polyurethanes segment. 

We accounted for the Icynene-Lapolla Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the Icynene-Lapolla Acquisition	$	353
Cash	$	7
Accounts receivable		36
Inventories		32
Prepaid expenses and other current assets		2
Property, plant and equipment		9
Intangible assets		130
Goodwill		167
Other noncurrent assets		4
Accounts payable		(14	)
Accrued liabilities		(11	)
Deferred income taxes		(9	)
Total fair value of net assets acquired	$	353

As a result of the final valuation of the assets and liabilities, reallocations were made during the first quarter of 2021 in certain current asset and liability, property, plant and equipment, intangible asset, goodwill, other noncurrent assets and deferred tax balances. Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, which are predominantly being amortized over a period of 10 years. The goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets and synergies. None of the goodwill arising from the acquisition is deductible for income tax purposes.

On November 3, 2020, we completed the sale of the India-based DIY business to Pidilite Industries Ltd. and received cash of approximately $257 million. Under the terms of the agreement, an earnout provision of up to approximately $28 million of additional cash was attainable if the business achieved, within 18 months, certain sales revenue targets in line with the DIY business' 2019 performance. The performance criteria of the earnout provision were satisfied in the second quarter of 2021, and we received the full payment of $28 million. As a result, we recognized an additional pretax gain of $28 million in the second quarter of 2021, which was recorded in gain on sale of India-based DIY business in our condensed consolidated statements of operations.

SaLE of Venator InterEST

On December 23, 2020, we completed the sale of approximately 42.4 million ordinary shares of Venator Materials PLC (“Venator”) and received approximately $99 million in cash. Subsequent to this sale of ordinary shares, we no longer account for our current remaining ownership interest in Venator as an equity method investment, but rather as an investment in equity securities that are marked to fair value with changes in fair value reported in earnings. Concurrently with the sale of ordinary shares, we entered into an option agreement, pursuant to which we granted an option to funds advised by SK Capital Partners, LP to purchase the remaining approximate 9.7 million ordinary shares we hold in Venator at $2.15 per share. The option will expire on June 23, 2023 and will not be exercisable so long as such exercise would result in a default or an "Event of Default" under Venator’s Term Loan Credit Agreement and Revolving Credit Agreement. We record this option at fair value with changes in fair value reported in earnings.

For the three months ended September 30, 2021 and 2020, we recorded net (losses) gains of $( 3) million and $6 million, respectively, and for the nine months ended  September 30, 2021 and 2020, we recorded net losses of $28 million and $100 million, respectively, to record our investment in Venator and related option to sell our remaining Venator shares at fair value. These net (losses) gains were recorded in “Fair value adjustments to Venator investment” in our condensed consolidated statements of operations.

Summarized financial information of Venator for the three and nine months ended September 30, 2020 is as follows (in millions):

	Three months			Nine months

Sale of Chemical Intermediates Businesses​

On January 3, 2020, we completed the sale of our chemical intermediates businesses, which included PO/MTBE, and our surfactants business (“Chemical Intermediates Businesses”) to Indorama Ventures Holdings L.P. (“Indorama”) in a transaction valued at approximately $2 billion, comprised of a cash purchase price of approximately $1.92 billion and the transfer of approximately $72 million in net underfunded pension and other post-employment benefit liabilities. In connection with this sale, we recognized a net after-tax gain of $748 million in the first nine months of 2020. Also, in connection with this sale, we entered into long-term supply agreements with Indorama to supply us with certain raw materials at market prices.

Direct and Subsidiary Debt

Huntsman Corporation’s direct debt and guarantee obligations consist of a guarantee of certain indebtedness incurred from time to time to finance certain insurance premiums. 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 September 30, 2021 and December 31, 2020, the amount of debt issuance costs directly reducing the debt liability was $10 million and $9 million, respectively. We record the amortization of debt issuance costs as interest expense.

Revolving Credit Facility

As of September 30, 2021, our $1.2 billion senior unsecured revolving credit facility (“Revolving Credit Facility”) was as follows (monetary amounts in millions):

						Unamortized
						Discounts and
	Committed		Principal			Debt Issuance			Carrying
Facility	Amount		Outstanding			Costs			Value			Interest Rate(2)	Maturity
Revolving Credit Facility	$	1,200	$	—	(1)	$	—	(1)	$	—	(1)	USD LIBOR plus 1.50%		2023

(2) Interest rates on borrowings under the Revolving Credit Facility vary based on the type of loan and Huntsman International’s debt ratings. The representative interest rate as of September 30, 2021 was 1.50% above LIBOR.

24

Term Loan Credit Facility

On September 24, 2019, Huntsman International entered into a 364-day term loan facility (the “2019 Term Loan”), pursuant to which Huntsman International borrowed an aggregate principal amount of €92 million (or $101 million equivalent). We used the net proceeds from the 2019 Term Loan to finance our acquisition of the 50% noncontrolling interest that we did not own in the Sasol-Huntsman maleic anhydride joint venture. On September 22, 2020, we repaid the 2019 Term Loan in full at maturity.

A/R Programs

Our 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.

On July 1, 2021, we entered into amendments to our A/R Programs that, among other things, extended the respective scheduled termination dates of our A/R Programs from April 2022 to July 2024.

Information regarding our A/R Programs as of September 30, 2021 was as follows (monetary amounts in millions):

		Maximum Funding		Amount
Facility	Maturity	Availability(1)		Outstanding			Interest Rate(2)
U.S. A/R Program	July 2024	$	150	$	—	(3)	Applicable rate plus 0.90%
EU A/R Program	July 2024	€	100	€	—		Applicable rate plus 1.30%
		(or approximately $117)

(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 USD LIBOR or EURIBOR.

(3) As of September 30, 2021, we had approximately $7 million (U.S. dollar equivalents) of letters of credit issued and outstanding under our U.S. A/R Program.

As of September 30, 2021 and December 31, 2020, $336 million and $198 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs.

Senior Notes

On January 15, 2021, Huntsman International redeemed in full €445 million (approximately $541 million) in aggregate principal amount of our 5.125% senior notes due 2021 (“2021 Senior Notes”) at the redemption price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest to, but not including, the redemption date. In connection with this redemption, we incurred an incremental cash tax liability of approximately $15 million in the first quarter of 2021 related to foreign currency exchange gains.

On May 26, 2021, Huntsman International completed a $400 million offering of its 2031 Senior Notes. On June 23, 2021, Huntsman International applied the net proceeds from the offering, along with cash on hand, to redeem in full $400 million in aggregate principal amount of its 2022 Senior Notes and to pay accrued but unpaid interest of approximately $2 million. In addition, we paid redemption premiums and related fees and expenses of approximately $25 million and recognized a corresponding loss on early extinguishment of debt of $26 million in the second quarter of 2021.

The 2031 Senior Notes bear interest at 2.95% per year, payable semi‑annually on June 15 and December 15 of each year, and will mature on June 15, 2031. Huntsman International may redeem the 2031 Senior Notes in whole or in part at any time prior to March 15, 2031 at a price equal to 100% of the principal amount thereof plus a “make‑whole” premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption. Huntsman International may redeem the 2031 Senior Notes at any time in whole or from time to time in part, on or after March 15, 2031 at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of redemption. ​

Variable Interest Entity Debt

On September 30, 2021, AAC, our consolidated 50%-owned joint venture, entered into a new term loan facility of 177 million SAR (approximately $47 million) with Saudi British Bank, of which approximately 104 million SAR (approximately $27 million) was funded with the remainder being funded subsequent to September 30, 2021. A portion of these funds were used to repay existing debt subsequent to September 30, 2021. 

Note Payable from Huntsman International to Huntsman Corporation

 ​During the first quarter of 2020, our intercompany 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 Revolving Credit Facility, our A/R Programs and our senior notes.​

9. 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 September 30, 2021, we had approximately $178 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. 

We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of September 30, 2021, we have designated approximately €120 million (approximately $140 million) of euro-denominated debt as a hedge of our net investment. For the nine months ended September 30, 2021 and September 30, 2020, the amount recognized on the hedge of our net investment was a gain of $7 million and a loss of $31 million, respectively, and were recorded in other comprehensive income in our condensed consolidated statements of comprehensive income.​ 

10. FAIR VALUE

The fair values of financial instruments were as follows (dollars in millions):

	September 30, 2021						December 31, 2020
	Carrying			Estimated			Carrying			Estimated
	Value			Fair Value			Value			Fair Value
Non-qualified employee benefit plan investments	$	22		$	22		$	26		$	26
Investment in Venator		28			28			32			32
Option agreement for remaining Venator shares		(10	)		(10	)		11			11
Long-term debt (including current portion)		(1,583	)		(1,755	)		(2,121	)		(2,334	)

The carrying amounts reported in the balance sheets of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments. Our investment in Venator is marked to fair value, which is obtained through market observable pricing using prevailing market prices (Level 1). Additionally, the estimated fair value of the option agreement related to the remaining ordinary shares we hold in Venator is based on a valuation technique using market observable inputs (Level 2). See “Note 4. Discontinued Operations and Business Dispositions—Sale of Venator Interest.” The fair values of non-qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices (Level 1). The estimated fair values of our long-term debt are based on quoted market prices for the identical liability when traded in an active market (Level 1). The fair value estimates presented herein are based on pertinent information available to management as of  September 30, 2021 and December 31, 2020. Although we are 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 September 30, 2021, and current estimates of fair value may differ significantly from the amounts presented herein.

During the nine months ended September 30, 2021, there were no instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3), and there were no gains or losses (realized and unrealized) included in earnings for instruments categorized as Level 3 within the fair value hierarchy.

13. HUNTSMAN CORPORATION STOCKHOLDERS’ EQUITY

Share Repurchase Program

On February 7, 2018 and on May 3, 2018, our Board of Directors collectively authorized us to repurchase up to an aggregate of $1 billion in shares of our common stock. The share repurchase program is supported by our free cash flow generation. Repurchases may be made through the open market, including through accelerated share repurchase programs, or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. Subsequent to the end of the first quarter of 2020, we suspended share repurchases under our existing share repurchase program in order to enhance our liquidity position in response to COVID-19. During the third quarter of 2021, we resumed the share repurchase program and repurchased 3,971,784 shares of our common stock for approximately $102 million, excluding commissions. 

Dividends on Common Stock

On April 28, 2021, our Board of Directors declared a $0.1875 per share cash dividend on our common stock. This represents a 15% increase from the previous dividend. During the quarters ended September 30, 2021 and  September 30, 2020, we paid $42 million and $36 million, respectively, or $0.1875 and $0.1625 per share, respectively, to common stockholders. During the quarters ended June 30, 2021 and June 30, 2020, we paid $41 million and $36 million, respectively, or $0.1875 and $0.1625 per share, respectively, to common stockholders. During the quarters ended and March 31, 2021 and March 31, 2020, we paid $36 million and $37 million, respectively, or $0.1625 per share each to common stockholders.

15. COMMITMENTS AND CONTINGENCIES

Legal Matters

We are a party to various 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.

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 nine months ended September 30, 2021 and 2020, our capital expenditures for EHS matters totaled $25 million and $17 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 $5 million and $4 million for environmental liabilities as of  September 30, 2021 and December 31, 2020, respectively. Of these amounts, $2 million and $1 million were classified as accrued liabilities in our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively, and $3 million was classified as other noncurrent liabilities in our condensed consolidated balance sheets as of both  September 30, 2021 and December 31, 2020. 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 Geismar, Louisiana facility is 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. At this time, we are unable to reasonably estimate our potential liabilities at this site.

17. STOCK-BASED COMPENSATION PLANS

As of September 30, 2021, 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				Nine months
	ended				ended
	September 30,				September 30,
	2021		2020		2021		2020
Huntsman Corporation compensation cost	$	8	$	6	$	24	$	20
Huntsman International compensation cost		8		6		23		19

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 $3 million for the nine months ended September 30, 2021 and 2020, 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.

	Three months					Nine months
	ended					ended
	September 30,					September 30,
	2021(1)		2020			2021			2020
Dividend yield		NA		3.1	%		2.3	%		3.0	%
Expected volatility		NA		53.7	%		53.3	%		53.1	%
Risk-free interest rate		NA		0.4	%		0.7	%		1.4	%
Expected life of stock options granted during the period (in years)		NA		5.9			5.9			5.9

(1) During the three months ended  September 30, 2021, no stock options were granted.

A summary of stock option activity under the stock-based compensation plans as of September 30, 2021 and changes during the nine 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, 2021		4,815		$	20.37
Granted		304			28.58
Exercised		(697	)		17.44
Forfeited		(71	)		24.29
Outstanding at September 30, 2021		4,351			21.35		5.8	$	37
Exercisable at September 30, 2021		3,309			20.59		5.0		31

34

The weighted-average grant-date fair value of stock options granted during the nine months ended September 30, 2021 was $11.48 per option. As of September 30, 2021, there was $6 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 1.7 years.

The total intrinsic value of stock options exercised during the nine months ended September 30, 2021 and 2020 was approximately $8 million and $4 million, respectively. Cash received from stock options exercised during each of the nine months ended September 30, 2021 and 2020 was approximately $6 million and $2 million, respectively. The cash tax benefit from stock options exercised during each of the nine months ended September 30, 2021 and 2020 was approximately $2 million and $1 million, respectively.

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 nine months ended September 30, 2021 and 2020, the weighted-average expected volatility rate was 44.9% and 34.0%, respectively, and the weighted average risk-free interest rate was 0.2% and 1.4%, respectively. For the performance share unit awards granted in the nine months ended September 30, 2021 and 2020, 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 September 30, 2021 and changes during the nine 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, 2021		1,867			$	23.18		411		$	23.08

Nonvested at September 30, 2021		2,185				25.07		386			24.92

(1) As of September 30, 2021, a total of 457,294 restricted stock units were vested but not yet issued, of which 30,438 vested during the nine months ended September 30, 2021. 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 110,542 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, 2020. During the nine months ended September 30, 2021, only 76,055 performance share unit awards with a grant date fair value of $41.93 were issued related to this vest due to the target performance criteria not being met.

As of September 30, 2021, there was $36 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the stock-based compensation plans. That cost is expected to be recognized over a weighted-average period of approximately 2.0 years. The value of share awards that vested during the nine months ended September 30, 2021 and 2020 was $18 million and $24 million, respectively.

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 nine months ended September 30, 2021 and 2020, there was no tax benefit or expense recognized in connection with the net losses of $28 million and $100 million, respectively, on fair value adjustments to our Venator investment and related option to sell our remaining Venator shares recorded as part of non-operating income from continuing operations. As of December 31, 2019, we have recognized the portion of our Venator investment tax basis in excess of book that we ultimately expect to be able to utilize; therefore, no incremental tax benefit has been recognized on the year-to-date fair value losses incurred in 2020 or 2021. As a significant, unusual and non-operating item, these amounts were 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 $114 million and $9 million for the nine months ended September 30, 2021 and 2020, 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. 

Huntsman International

Huntsman International recorded income tax expense from continuing operations of $115 million and $9 million for the nine months ended September 30, 2021 and 2020, 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.

19. EARNINGS PER SHARE

Basic earnings 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 earnings per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable 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 earnings per share is determined using the following information (in millions):

	Three months				Nine months
	ended				ended
	September 30,				September 30,
	2021		2020		2021		2020
Numerator:

Total weighted average shares outstanding, including dilutive shares		221.3		221.3		222.2		220.8

Additional stock-based awards of approximately 1.0 million and 3.8 million weighted average equivalent shares of stock were outstanding during the three months ended September 30, 2021 and 2020, respectively, and approximately 1.5 million and 6.1 million weighted average shares of stock were outstanding during the nine months ended September 30, 2021 and 2020, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the three and nine months ended September 30, 2021 and 2020 because the effect would be anti-dilutive.

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.

The major products of each reportable operating segment are as follows:

Segment	Products
Polyurethanes	MDI, polyols, TPU and other polyurethane-related products
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 and toughening agents; epoxy, acrylic and polyurethane-based formulations; specialty nitrile latex, alkyd resins and carbon nano materials
Textile Effects	Textile chemicals and dyes

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. The adjusted EBITDA of our reportable operating segments excludes items that principally apply to our Company as a whole. The revenues and adjusted EBITDA from continuing operations for each of our reportable operating segments are as follows (dollars in millions):

(1) We use segment adjusted EBITDA as the measure of each segment’s profit or loss. We believe that segment adjusted EBITDA more accurately reflects what the chief operating decision maker uses to make decisions about resources to be allocated to the segments and assess their financial performance. Segment adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) EBITDA from discontinued operations; (c) fair value adjustments to Venator investment; (d) loss on early extinguishment of debt; (e) certain legal and other settlements and related income (expenses); (f) gain on sale of businesses/assets; (g) income from transition services arrangements related to the sale of our Chemical Intermediates Businesses to Indorama; (h) certain nonrecurring information technology project implementation costs; (i) amortization of pension and postretirement actuarial losses; (j) plant incident remediation costs; and (k) restructuring, impairment, plant closing and transition costs.

(2) Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets.

(3) Includes the gain on the sale of our Chemical Intermediates Businesses in 2020.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

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, 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. Our revenues from continuing operations for the nine months ended September 30, 2021 and 2020 were $6,146 million and $4,350 million, respectively.

Recent Developments 

Amendments to Accounts Receivable Securitization Programs

On July 1, 2021, we entered into amendments to our A/R Programs that, among other things, extended the scheduled termination dates of our A/R Programs from April 2022 to July 2024. For additional information, see “Note 8. Debt—Direct and Subsidiary Debt—A/R Programs” to our condensed consolidated financial statements.

39

Outlook 

We expect the following factors to impact our operating segments:

Polyurethanes:

● Fourth quarter 2021 adjusted EBITDA estimated to be between $200 million and $220 million

● Positive trends in construction, though impacted by raw material constraints

● Automotive market continues to be weak

Performance Products:

● Fourth quarter 2021 adjusted EBITDA estimated to be between $95 million and $100 million

● Commercial initiatives to positively impact results

Advanced Materials:

● Fourth quarter 2021 adjusted EBITDA estimated to be between $47 million and $52 million

● Aerospace continues to recover

● Pricing increases to offset raw material cost increases

Textile Effects

● Fourth quarter 2021 adjusted EBITDA estimated to be between $20 million and $22 million

● Favorable trends in sustainable solutions

● Pricing increases to offset raw material cost increases

In the third quarter of 2021, our adjusted effective tax rate was 15%. For 2021, our adjusted effective tax rate is expected to be approximately 19% to 20%, which is below our previously expected rate of approximately 22% to 24% due largely to tax benefits for increased export sales and services taxed at a U.S. income tax rate lower than 21%. We continue to expect our forward adjusted effective tax rate will be approximately 22% to 24%. For further information, see “—Non-GAAP Financial Measures” and “Note 18. Income Taxes” to our condensed consolidated financial statements.

Refer to “Forward-Looking Statements” for a discussion of our use of forward-looking statements in this Quarterly Report on Form 10-Q.

Non-GAAP Financial Measures

Our condensed consolidated financial statements are prepared in accordance with GAAP, which we supplement with certain non-GAAP financial information. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to review our financial statements and the reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures in their entirety and not to rely on any single financial measure. These non-GAAP measures exclude the impact of certain income and expenses that we do not believe are indicative of our core operating results.

Adjusted EBITDA

Our management uses adjusted EBITDA to assess financial performance. Adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) EBITDA from discontinued operations; (c) fair value adjustments to Venator investment; (d) loss on early extinguishment of debt; (e) certain legal and other settlements and related (income) expenses; (f) gain on sale of businesses/assets; (g) income from transition services arrangements related to the sale of our Chemical Intermediates Businesses to Indorama; (h) certain nonrecurring information technology project implementation costs; (i) amortization of pension and postretirement actuarial losses; (j) plant incident remediation costs; and (k) restructuring, impairment and plant closing and transition costs. We believe that net income of Huntsman Corporation or Huntsman International, as appropriate, is the performance measure calculated and presented in accordance with U.S. GAAP that is most directly comparable to adjusted EBITDA.

We believe adjusted EBITDA is useful to investors in assessing the businesses’ ongoing financial performance and provides improved comparability between periods through the exclusion of certain items that management believes are not indicative of the businesses’ operational profitability and that may obscure underlying business results and trends. However, this measure should not be considered in isolation or viewed as a substitute for net income of Huntsman Corporation or Huntsman International, as appropriate, or other measures of performance determined in accordance with U.S. GAAP. Moreover, adjusted EBITDA as used herein is not necessarily comparable to other similarly titled measures of other companies due to potential inconsistencies in the methods of calculation. Our management believes this measure is useful to compare general operating performance from period to period and to make certain related management decisions. Adjusted EBITDA is also used by securities analysts, lenders and others in their evaluation of different companies because it excludes certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be highly dependent on a company’s capital structure, debt levels and credit ratings. Therefore, the impact of interest expense on earnings can vary significantly among companies. In addition, the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. As a result, effective tax rates and tax expense can vary considerably among companies. Finally, companies employ productive assets of different ages and utilize different methods of acquiring and depreciating such assets. This can result in considerable variability in the relative costs of productive assets and the depreciation and amortization expense among companies.

Nevertheless, our management recognizes that there are material limitations associated with the use of adjusted EBITDA in the evaluation of our Company as compared to net income of Huntsman Corporation or Huntsman International, as appropriate, which reflects overall financial performance. For example, we have borrowed money in order to finance our operations and interest expense is a necessary element of our costs and ability to generate revenue. Our management compensates for the limitations of using adjusted EBITDA by using this measure to supplement U.S. GAAP results to provide a more complete understanding of the factors and trends affecting the business rather than U.S. GAAP results alone.

Adjusted Net Income

Adjusted net income is computed by eliminating the after-tax amounts related to the following from net income attributable to Huntsman Corporation: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) loss (income) from discontinued operations; (c) fair value adjustments to Venator investment; (d) loss on early extinguishment of debt; (e) certain legal and other settlements and related (income) expenses; (f) gain on sale of businesses/assets; (g) income from transition services arrangements related to the sale of our Chemical Intermediates Businesses to Indorama; (h) certain nonrecurring information technology project implementation costs; (i) amortization of pension and postretirement actuarial losses; (j) plant incident remediation costs; and (k) restructuring, impairment and plant closing and transition costs. Basic adjusted net income per share excludes dilution and is computed by dividing adjusted net income by the weighted average number of shares outstanding during the period. Adjusted diluted net income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing adjusted net income 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. Adjusted net income and adjusted net income per share amounts are presented solely as supplemental information.

We believe adjusted net income is useful to investors in assessing the businesses’ ongoing financial performance and provides improved comparability between periods through the exclusion of certain items that management believes are not indicative of the businesses’ operational profitability and that may obscure underlying business results and trends.

Free Cash Flow

We believe free cash flow is an important indicator of our liquidity as it measures the amount of cash we generate. Management internally uses a free cash flow measure: (a) to evaluate our liquidity, (b) evaluate strategic investments, (c) plan stock buyback and dividend levels and (d) evaluate our ability to incur and service debt. Starting with the quarter ended March 31, 2020, we updated our definition of free cash flow to a presentation more consistent with today’s market standard of net cash provided by operating activities less capital expenditures. Free cash flow is not a defined term under U.S. GAAP, and it should not be inferred that the entire free cash flow amount is available for discretionary expenditures.

Adjusted Effective Tax Rate

We believe that the effective tax rate of Huntsman Corporation or Huntsman International, as appropriate, is the performance measure calculated and presented in accordance with U.S. GAAP that is most directly comparable to adjusted effective tax rate. We believe our adjusted effective tax rate provides improved comparability between periods through the exclusion of certain items that management believes are not indicative of the businesses’ operational profitability and that may obscure underlying business results and trends. We do not provide reconciliations for adjusted effective tax rate on a forward-looking basis because we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as business acquisition and integration expenses, merger costs, certain legal and other settlements and related costs, gains on sale of businesses/assets and amortization of pension and postretirement actuarial losses. Each of such adjustments has not yet occurred, is out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

Three Months Ended September 30, 2021 Compared with Three Months Ended September 30, 2020 

As discussed in “Note 4. Discontinued Operations and Business Dispositions—Sale of Chemical Intermediates Businesses” to our condensed consolidated financial statements, the results from continuing operations exclude the results of our Chemical Intermediates Businesses and the results of our former polymers, base chemicals and Australian styrenics businesses for all periods presented. The increase of $166 million in net income from continuing operations attributable to Huntsman Corporation and the increase of $165 million in net income from continuing operations attributable to Huntsman International was the result of the following items:

● Revenues for the three months ended September 30, 2021 increased by $775 million, or 51%, as compared with the 2020 period. The increase was primarily due to higher average selling prices as well as higher sales volumes in all our segments. See “—Segment Analysis” below.

● Gross profit for the three months ended September 30, 2021 increased by $204 million, or 73%, as compared with the 2020 period. The increase resulted from higher gross profits in all our segments. See “—Segment Analysis” below.

● Operating expenses, net for the three months ended September 30, 2021 increased by $31 million, or 15%, as compared with the 2020 period, primarily related to an increase in selling, general and administrative expenses.

● For the three months ended September 30, 2021, we recorded a credit of $1 million in restructuring, impairment and plant closing (credits) costs compared with costs of $12 million in the 2020 period. For more information concerning restructuring activities, see “Note 7. Restructuring, Impairment and Plant Closing Costs” to our condensed consolidated financial statements.

● Interest expense, net for the three months ended September 30, 2021 decreased by $9 million, or 38%, as compared with the 2020 period, primarily related to the redemption in full of our 2021 Senior Notes in the first half of 2021.

● Equity in income of investment in unconsolidated affiliates for the three months ended September 30, 2021 increased to $34 million from $21 million in the 2020 period, primarily related to an increase in income at our PO/MTBE joint venture in China, in which we hold a 49% interest.

● For the three months ended September 30, 2021, we recorded a net loss of $3 million in fair value adjustments to our investment in Venator and related option to sell our remaining Venator shares compared with a gain of $6 million in the 2020 period. See “Note 4. Business Dispositions—Sale of Venator Interest” to our condensed consolidated financial statements.

● Our income tax expense for the three months ended September 30, 2021 increased to $38 million from $15 million in the 2020 period. The income tax expense of Huntsman International for the three months ended September 30, 2021 increased to $39 million from $15 million in the 2020 period. The increase in income tax expense was primarily due to the increase in pretax income, exclusive of the fair value adjustments to our investment in Venator, partially offset by approximately $11 million of tax benefits for increased export sales and services taxed at a U.S. income tax rate lower than 21% in the third quarter of 2021. Our income 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. For further information concerning income taxes, see “Note 18. Income Taxes” to our condensed consolidated financial statements.

Polyurethanes

The increase in revenues in our Polyurethanes segment for the three months ended September 30, 2021 compared to the same period of 2020 was largely due to higher MDI average selling prices and slightly higher sales volumes. MDI average selling prices increased in all our regions. Sales volumes increased primarily due to stronger demand in relation to the ongoing recovery from the global economic slowdown, partially offset by the impact of Hurricane Ida at our Geismar, Louisiana facility that occurred in the third quarter of 2021. The increase in segment adjusted EBITDA was primarily due to higher MDI margins resulting from higher MDI pricing and slightly higher sales volumes as well as stronger earnings from our PO/MTBE joint venture in China, partially offset by higher raw material costs. 

​Performance Products 

The increase in revenues in our Performance Products segment for the three months ended September 30, 2021 compared to the same period of 2020 was primarily due to higher average selling prices and higher sales volumes. Average selling prices increased primarily due to stronger demand in relation to the ongoing recovery from the global economic slowdown as well as in response to an increase in raw material costs. Sales volumes also increased primarily due to stronger demand. The increase in segment adjusted EBITDA was primarily due to increased revenue and margins, partially offset by increased fixed costs.

Advanced Materials 

The increase in revenues in our Advanced Materials segment for the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to higher sales volumes, higher average selling prices and the favorable net impact of the Gabriel Acquisition and the sale of the India-based DIY business. See “Note 3. Business Combinations and Acquisitions” and “Note 4. Discontinued Operations and Business Dispositions” to our condensed consolidated financial statements. Excluding our recent acquisition and divestiture, sales volumes increased across all of our specialty markets, primarily in relation to the ongoing recovery from the global economic slowdown. Average selling prices increased largely in response to higher raw material costs. The increase in segment adjusted EBITDA was primarily due to higher sales volumes and the benefit from our recent acquisition.

Textile Effects

The increase in revenues in our Textile Effects segment for the three months ended September 30, 2021 compared to the same period of 2020 was due to higher sales volumes and higher average selling prices. Sales volumes increased primarily due to increased demand resulting from the ongoing recovery from the global economic slowdown, particularly in the North Asia and Americas regions. Average selling prices increased primarily in response to higher freight and logistics costs. The increase in segment adjusted EBITDA was primarily due to higher sales revenues, partially offset by higher fixed costs.

Corporate and other 

Corporate and other includes unallocated corporate overhead, unallocated foreign currency exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets. For the three months ended September 30, 2021, adjusted EBITDA from Corporate and other for Huntsman Corporation decreased by $11 million to a loss of $48 million from a loss of $37 million for the same period of 2020. For the three months ended September 30, 2021, adjusted EBITDA from Corporate and other for Huntsman International decreased by $11 million to a loss of $47 million from a loss of $36 million for the same period of 2020. The decrease in adjusted EBITDA from Corporate and other was primarily due to a charge from a LIFO inventory valuation reserve adjustment and an increase in corporate overhead costs, partially offset by an increase in unallocated foreign currency exchange gains.

Nine Months Ended September 30, 2021 Compared with Nine Months Ended September 30, 2020 

As discussed in “Note 4. Discontinued Operations and Business Dispositions—Sale of Chemical Intermediates Businesses” to our condensed consolidated financial statements, the results from continuing operations exclude the results of our Chemical Intermediates and Businesses and the results of our former polymers, base chemicals and Australian styrenics business for all periods presented. The increase of $542 million in net income from continuing operations attributable to Huntsman Corporation and the increase of $545 million in net income from continuing operations attributable to Huntsman International was the result of the following items:

● Revenues for the nine months ended September 30, 2021 increased by $1,796 million, or 41%, as compared with the 2020 period. The increase was primarily due to higher average selling prices as well as higher sales volumes in all our segments. See “—Segment Analysis” below.

● Our interest expense, net and interest expense, net of Huntsman International for the nine months ended September 30, 2021 decreased by $11 million and $13 million, respectively, or 17% and 20%, respectively, as compared with the 2020 period, primarily related to the redemption in full of our 2021 Senior Notes in the first half of 2021.

● Equity in income of investment in unconsolidated affiliates for the nine months ended September 30, 2021 increased to $118 million from $25 million in the 2020 period, primarily related to an increase in income at our PO/MTBE joint venture in China, in which we hold a 49% interest.

● For the nine months ended September 30, 2021, we recorded a net loss of $28 million in fair value adjustments to our investment in Venator and related option to sell our remaining Venator shares compared with a loss of $100 million in the 2020 period. See “Note 4. Business Dispositions—Sale of Venator Interest” to our condensed consolidated financial statements.

● Loss on early extinguishment of debt for the nine months ended September 30, 2021 was $27 million compared with nil in the 2020 period, primarily due to the full redemption of our 2022 Senior Notes in the second quarter of 2021.

Polyurethanes

The increase in revenues in our Polyurethanes segment for the nine months ended September 30, 2021 compared to the same period of 2020 was largely due to higher MDI average selling prices and higher sales volumes. MDI average selling prices increased mostly in China and Europe with increases in our Americas region during the third quarter of 2021. Sales volumes increased primarily due to stronger demand in relation to the ongoing recovery from the global economic slowdown, partially offset by some unplanned downtime resulting from the U.S. Gulf Coast Winter Storm Uri that occurred in the first quarter of 2021, the scheduled turnaround at our Rotterdam, Netherlands facility during the second quarter of 2021 and the impact of Hurricane Ida at our Geismar, Louisiana facility that occurred in the third quarter of 2021. The increase in segment adjusted EBITDA was primarily due to higher MDI margins resulting from higher MDI pricing and higher sales volumes as well as stronger earnings from our PO/MTBE joint venture in China, partially offset by higher raw material costs

​Performance Products

The increase in revenues in our Performance Products segment for the nine months ended September 30, 2021 compared to the same period of 2020 was primarily due to higher average selling prices and higher sales volumes. Average selling prices increased primarily due to stronger demand in relation to the ongoing recovery from the global economic slowdown as well as in response to an increase in raw material costs. Sales volumes also increased primarily due to stronger demand. The increase in segment adjusted EBITDA was primarily due to increased revenue and margins, partially offset by increased fixed costs.

Advanced Materials

The increase in revenues in our Advanced Materials segment for the nine months ended September 30, 2021 compared to the same period in 2020 was primarily due to higher sales volumes, higher average selling prices and the favorable net impact of the CVC Thermoset Specialties Acquisition, the Gabriel Acquisition and the sale of the India-based DIY business. See “Note 3. Business Combinations and Acquisitions” and “Note 4. Discontinued Operations and Business Dispositions” to our condensed consolidated financial statements. Excluding our recent acquisitions and divestiture and with the exception of our global aerospace business, sales volumes increased across all markets, primarily in relation to the ongoing recovery from the global economic slowdown. Average selling prices increased largely in response to higher raw material costs and due to the impact of a weaker U.S. dollar against major international currencies. The increase in segment adjusted EBITDA was primarily due to higher sales volumes and the benefit from our recent acquisitions.

Textile Effects 

The increase in revenues in our Textile Effects segment for the nine months ended September 30, 2021 compared to the same period of 2020 was primarily due to higher sales volumes and slightly higher average selling prices. Sales volumes increased primarily due to increased demand resulting from the ongoing recovery from the global economic slowdown. Average selling prices slightly increased primarily due to the impact of a weaker U.S. dollar against major international currencies. The increase in segment adjusted EBITDA was primarily due to higher sales revenues, partially offset by higher fixed costs.

Corporate and other

Corporate and other includes unallocated corporate overhead, unallocated foreign currency exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets. For the nine months ended September 30, 2021, adjusted EBITDA from Corporate and other for Huntsman Corporation decreased by $32 million to a loss of $146 million from a loss of $114 million for the same period of 2020. For the nine months ended September 30, 2021, adjusted EBITDA from Corporate and other for Huntsman International decreased by $30 million to a loss of $140 million from a loss of $110 million for the same period of 2020. The decrease in adjusted EBITDA from Corporate and other was primarily due to a charge from a LIFO inventory valuation reserve adjustment and an increase in corporate overhead costs, partially offset by an increase in unallocated foreign currency exchange gains.

Liquidity and Capital Resources

The following is a discussion of our liquidity and capital resources and does not include separate information with respect to Huntsman International in accordance with General Instructions H(1)(a) and (b) of Form 10-Q.

Cash Flows for the Nine Months Ended September 30, 2021 Compared with Nine Months Ended September 30, 2020 

Net cash provided by operating activities from continuing operations for the nine months ended September 30, 2021 and 2020 was $163 million and $110 million, respectively. The increase in net cash provided by operating activities from continuing operations during the nine months ended September 30, 2021 compared with the same period in 2020 was primarily attributable to increased operating income as described in “—Results of Operations” above for the nine months ended September 30, 2021 as compared with the same period of 2020, partially offset by a $382 million unfavorable variance in operating assets and liabilities.

Net cash (used in) provided by investing activities for the nine months ended September 30, 2021 and 2020 was $(439) million and $1,105 million, respectively. During the nine months ended September 30, 2021 and 2020, we paid $250 million and $170 million for capital expenditures, respectively. During the nine months ended September 30, 2021, we received $43 million for the sale of businesses, primarily due to the receipt of $28 million pursuant to an earnout provision in connection with the sale of our India-based DIY business, and we paid $245 million for the acquisition of businesses, primarily related to approximately $242 million paid for the Gabriel Acquisition, net of cash acquired. During the nine months ended September 30, 2020, we received approximately $1.92 billion for the sale of our Chemical Intermediates Businesses, and we paid $653 million in connection with the Icynene-Lapolla Acquisition and the CVC Thermoset Specialties Acquisition, net of cash acquired.

Net cash used in financing activities for the nine months ended September 30, 2021 and 2020 was $809 million and $546 million, respectively. During the nine months ended September 30, 2021, we redeemed in full €445 million (approximately $541 million) in aggregate principal amount of our 2021 Senior Notes, and we redeemed in full $400 million in aggregate principal amount of our 2022 Senior Notes. Additionally, during the nine months ended September 30, 2021, we issued $400 million in aggregate principal amount of our 2031 Senior Notes and received borrowings of approximately 104 million SAR (approximately $27 million) related to funding on a new term loan facility of our consolidated 50%-owned joint venture, AAC. See “Note 8. Debt—Direct and Subsidiary Debt—Variable Interest Entity Debt” to our condensed consolidated financial statements. During the nine months ended September 30, 2020, we repaid a total of $153 million on our Revolving Credit Facility and repaid in full $109 million on our 2019 Term Loan in the third quarter of 2020.

​Free cash flow from continuing operations for the nine months ended September 30, 2021 and 2020 was a use of cash of $87 million and $60 million, respectively.

​Our working capital decreased by $138 million as a result of the net impact of the following significant changes:

● The decrease in cash and cash equivalents of $1,097 million resulted from the matters identified on our condensed consolidated statements of cash flows.

● Accounts receivable increased by $316 million due to higher revenues in the third quarter of 2021 compared to the fourth quarter of 2020.

● Inventories increased by $300 million primarily due to higher inventory costs and volumes.

● Accounts payable increased by $102 million primarily due to higher inventory purchases.

● Accrued liabilities increased by $109 million primarily related to higher accrued compensation and current income taxes payable.

● Current portion of debt decreased by $577 million primarily due to the redemption of our 2021 Senior Notes in the first half of 2021.

54

We depend upon our cash, Revolving Credit Facility, A/R Programs and other debt instruments to provide liquidity for our operations and working capital needs. As of September 30, 2021, we had $1,955 million of combined cash and unused borrowing capacity, consisting of $505 million in cash, $1,190 million in availability under our Revolving Credit Facility and $260 million in availability under our A/R Programs. Our liquidity can be significantly impacted by various factors. The following matters are expected to have a significant impact on our liquidity:

Short-Term Liquidity

● Cash invested in our accounts receivable and inventory, net of accounts payable, was approximately $546 million for the nine months ended September 30, 2021, as reflected in our condensed consolidated statements of cash flows. We expect volatility in our working capital components to continue.

● During 2021, we expect to spend approximately $350 million on capital expenditures, including spending of approximately $100 million on a new MDI splitter in Geismar, Louisiana. We expect to fund capital expenditures with cash provided by operations. 

● During the nine months ended September 30, 2021, we made contributions to our pension and postretirement benefit plans of $45 million. During 2021, we expect to contribute an additional amount of approximately $9 million to these plans.

● On February 7, 2018 and on May 3, 2018, our Board of Directors collectively authorized us to repurchase up to an aggregate of $1 billion in shares of our common stock. During the three months and nine months ended September 30, 2021, we repurchased 3,971,784 shares of our common stock for approximately $102 million, excluding commissions, under the share repurchase program. 

Long-Term Liquidity

● On April 28, 2021, our Board of Directors declared a $0.1875 per share cash dividend on our common stock. This represents a 15% increase from the previous dividend. We expect to distribute an additional $5.5 million in dividends each quarter related to this dividend increase.

● On May 26, 2021, Huntsman International completed a $400 million offering of its 2031 Senior Notes. On June 23, 2021, Huntsman International applied the net proceeds from the offering, along with cash on hand, to redeem in full the $400 million in aggregate principal amount of its 2022 Senior Notes. For additional information, see “Note 8. Debt—Direct and Subsidiary Debt—Senior Notes” to our condensed consolidated financial statements. 

● On July 1, 2021, we entered into amendments to our A/R Programs that, among other things, extended the scheduled termination dates of our A/R Programs from April 2022 to July 2024.

● On a new MDI splitter being constructed in Geismar, Louisiana, we expect to spend approximately $50 million in the remainder of 2021 and 2022. We expect to fund capital expenditures with cash provided by operations. 

● During 2020, management implemented cost realignment and synergy plans. In connection with these plans, we expect to achieve annualized cost savings and synergy benefits of more than $120 million by the end of 2023 with associated net cash restructuring and integration costs of approximately $100 million. See “Note 7. Restructuring, Impairment and Plant Closing Cost” to our condensed consolidated financial statements.

As of September 30, 2021, we had $16 million classified as current portion of debt, including debt at our variable interest entities of $13 million and certain other short-term facilities and scheduled amortization payments totaling $3 million. We intend to renew, repay or extend the majority of these short-term facilities in the next twelve months.

As of September 30, 2021, we had approximately $365 million of cash and cash equivalents, including restricted cash, held by our foreign subsidiaries, including our variable interest entities. We intend to use cash held in our foreign subsidiaries to fund our local operations. Nevertheless, we could repatriate cash as dividends, which dividends would generally not be subject to U.S. taxation as a result of the U.S. Tax Reform Act. However, such repatriation may potentially be subject to certain foreign withholding taxes. ​

55

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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. See “Note 9. Derivative Instruments and Hedging Activities” to our condensed consolidated financial statements.

ITEM 4. CONTROLS AND PROCEDURES

Our management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2021. Based on this evaluation, our chief executive officer and chief financial officer have concluded that, as of September 30, 2021, our disclosure controls and procedures were effective, in that they ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and (2) accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

No changes to our internal control over financial reporting occurred during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). However, we can only give reasonable assurance that our internal controls over financial reporting will prevent or detect material misstatements on a timely basis. Ineffective internal controls over financial reporting could cause investors to lose confidence in our reported financial information and could result in a lower trading price for our securities.

56

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Except as set forth below, there have been no material developments with respect to the legal proceedings referenced in Part I, Item 3 of our Annual Report on Form 10-K for the year ended December 31, 2020.

Rockwood Litigation 

On February 6, 2017, we filed a lawsuit in New York state court against Rockwood Specialties Group, Inc., Rockwood Holdings, Inc. (collectively, “Rockwood”), Albemarle Corporation (as Rockwood’s successor) (“Albemarle”) and certain former Rockwood executives to recover damages for fraud and breach of contract in connection with our purchase of Rockwood’s pigments businesses, including its Color Pigments Division, for $1.1 billion in 2014. The case was ordered to arbitration under the rules of the American Arbitration Association and, after a two-week trial in May 2021, a panel consisting of three former federal judges awarded us in excess of $600 million for the fraud and breach, inclusive of punitive damages and statutory interest at 9%, of which we expect to net in excess of $400 million after attorney’s fees. The award is subject to confirmation and limited appeal in New York state court, and the arbitration panel directed us to file for reimbursement from Albemarle for attorney’s fees as prevailing party.

Texas Emissions Enforcement

On July 26, 2021, the Attorney General of the State of Texas filed a civil suit in the District Court of Travis County, Texas seeking civil penalties and attorney’s fees for alleged violations of the Texas Clean Air Act, Texas Commission on Environmental Quality regulations and facility permit terms. The complaint alleged multiple unauthorized emissions events and reporting discrepancies that occurred between December 2016 and June 2019 at our former manufacturing facility in Port Neches, Texas. The state is seeking monetary relief between $250,000 and $1 million. We completed the sale of our former Port Neches, Texas facility to Indorama Ventures Holdings L.P. on January 3, 2020. We believe that we are contractually indemnified for any defense costs and potential liability that may result from this action. 

ITEM 1A. RISK FACTORS

For information regarding risk factors, see “Part I. Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table provides information with respect to shares of our common stock that we repurchased as part of our share repurchase program and shares of restricted stock granted under our stock incentive plans that we withheld upon vesting to satisfy our tax withholding obligations during the three months ended September 30, 2021.

(2)

On February 7, 2018 and on May 3, 2018, our Board of Directors authorized us to repurchase up to an aggregate of $1 billion in shares of our common stock. The share repurchase program is supported by our free cash flow generation. Repurchases may be made in the open market, including through accelerated share repurchase programs, or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. Subsequent to the end of the first quarter of 2020, we suspended share repurchases under our existing share repurchase program in order to enhance our liquidity position in response to COVID-19. During the third quarter of 2021, we resumed the share repurchase program and repurchased 3,971,784 shares of our common stock for approximately $102 million, excluding commissions.

Dear Mr. Douglas:

This letter will confirm our agreement (this “Agreement”) for Sean Douglas (“Contractor”) to provide to Huntsman International LLC, a Delaware limited liability company, for and on behalf of its affiliates (“Huntsman”), during the term of this Agreement and in accordance with the provisions herein contained, independent consulting, advisory, or support services when requested and agreed to by both Huntsman and Contractor (collectively, the “Work”). Contractor agrees to perform all Work hereunder in a good, safe, professional, and lawful manner, consistent with all applicable industry standards.

Contractor will report administratively to, and receive Work assignments from, Peter Huntsman, or other Huntsman representatives as designated by Huntsman from time to time. Contractor shall make all reasonable efforts to be available to perform Work hereunder from time to time as requested by Huntsman and shall complete all such Work in a timely manner.

COMPENSATION.

Huntsman agrees to pay Contractor a fee for Work performed hereunder calculated at the fixed all-inclusive hourly rate of $300.00 per hour for each hour that Work is performed pursuant to this Agreement. Contractor agrees to accept such fee as full compensation for all Work performed by Contractor hereunder. Contractor acknowledges that Contractor is NOT an employee of Huntsman and shall NOT, by reason of this Agreement or any Work performed hereunder, be entitled to participate in any benefit plans available to Huntsman employees.

Contractor will invoice Huntsman monthly for Work performed under this Agreement during the preceding calendar month. Contractor shall send invoices (referencing the above Independent Services Agreement Number) to Huntsman at the following email address: ***@huntsman.com

Contractor represents and warrants to Huntsman that Contractor has a properly issued and validly held social security number or other documentation required to lawfully work in the United States. Huntsman will provide to Contractor an IRS Form 1099 (or equivalent form) in respect of compensation paid to Contractor under this Agreement. Contractor shall be solely responsible for the timely reporting and payment directly to the proper taxing authorities of all foreign, federal, state, and local taxes applicable to compensation paid to Contractor hereunder.

TERM AND TERMINATION.

The term of this Agreement shall be for a period commencing on August 1, 2021, and expiring at close of business on July 31, 2023 (the “Term”); provided, however, that Huntsman or Contractor may terminate this Agreement at any time, with or without cause, by giving the other party at least thirty (30) days prior written notice of such termination. Upon expiration or earlier termination of this Agreement, Contractor shall provide a list of pending projects.

CONFIDENTIAL INFORMATION.

In connection with this Agreement, Huntsman has disclosed or will disclose to Contractor, or Contractor has obtained or will obtain, directly or indirectly, by visual, oral, written (via whatsoever media), or other means, commercial or technical information of Huntsman or its affiliates or their licensors or others, including without limitation information relating to financial performance, products, product formulations, catalysts, evaluations, studies, data, ideas, plans, programs, suppliers, materials, customers, plants, equipment, processes, techniques, manufacturing, marketing, operations, personnel, research and development, know-how, or technology (collectively, the “Confidential Information”). Contractor agrees to use the Confidential Information only during the term of this Agreement and only for the purpose of performing the Work hereunder. Contractor shall protect the Confidential Information from disclosure to others, using the same degree of care used to protect Contractor’s own confidential or proprietary information of like importance, but no less than a reasonable degree of care. Contractor shall not disclose any Confidential Information to any third party without the prior written consent of Huntsman. Contractor’s obligations under this paragraph are perpetual and shall survive the expiration or earlier termination of this Agreement.

The restrictions contained in the preceding paragraph on use and disclosure of Confidential Information shall not apply to information that: (a) Was publicly known at the time of the communication thereof to Contractor; (b) becomes publicly known through no fault of Contractor subsequent to the time of the communication thereof to Contractor; (c) was in Contractor’s possession free of any obligation of confidence at the time of the communication thereof to Contractor; (d) is developed by Contractor independently of and without reference to any of the Confidential Information or other information that Huntsman or its affiliates have disclosed in confidence to any third party; or (e) is rightfully obtained by Contractor from third parties authorized to make such disclosure without restriction.

If Contractor is required by law, regulation, or court order to disclose any Confidential Information, Contractor shall promptly notify Huntsman in writing prior to making any such disclosure in order to facilitate Huntsman seeking a protective order or other appropriate remedy from the proper authority. Contractor agrees to cooperate with Huntsman in seeking such order or other remedy. All Confidential Information disclosed or obtained under this Agreement (including information in computer software or held in electronic or magnetic storage media) shall be and remain (as between the parties) the property of Huntsman. All such information in tangible form shall be returned to Huntsman promptly upon written request or upon the termination or expiration of this Agreement and shall not thereafter be retained in any form by Contractor.

OWNERSHIP OF WORK PRODUCT AND INVENTIONS.

All reports, drawings, data, models, correspondence, specifications, manuals, programs, and other documentation (in whatsoever media) provided to Huntsman by Contractor in connection with the Work (collectively, the “Work Product”) shall be “works made for hire” and all such Work Product, including the copyright therein, shall belong to and be the sole property of Huntsman, and may be utilized by Huntsman for any purpose at any location. If any Work Product shall for any reason be determined not to be “works made for hire,” then Contractor hereby assigns and transfers to Huntsman all of Contractor’s right, title, and interest in such Work Product. If any Work Product includes any materials previously patented or copyrighted by Contractor, then Contractor hereby grants to Huntsman and its affiliates irrevocable, non-exclusive, transferable, royalty free licenses under each such patent or copyright to employ or reproduce such Work Product in any manner for sale, distribution, or use.

INDEPENDENT CONTRACTOR.

Contractor shall have no authority to bind Huntsman to any agreements or other commitments. Contractor shall inform all persons with whom Contractor has dealings on behalf of Huntsman that Contractor is an independent contractor, and NOT an employee of Huntsman. Contractor shall NOT, explicitly or implicitly, give any appearance of having specific or apparent authority to bind Huntsman to any agreements or other commitments.

NOTICES.

Except for routine communications in the course of performance of this Agreement, which may be transmitted in accordance with any procedures established by agreement or acquiescence of the parties, all notices and other communications hereunder shall be in writing and shall be deemed to have been given and received when delivered by hand, or when sent by facsimile (with confirmation of receipt), or three days after sent by registered or certified US mail (one business day in the case of express US mail), or one business day after sent by reputable overnight courier service, in each case postage or delivery prepaid and addressed to the respective party at its address specified on the first page of this Agreement, or at such other address as such party may hereafter designate by written notice to the other party as herein provided.

Contractor shall at all times perform the Work and take all safety precautions and similar measures as may be warranted by the prevailing circumstances, applicable Laws, or Contractor’s or Huntsman’s applicable health and safety rules and requirements.

GENERAL PROVISIONS.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of Texas, without giving effect to its conflicts of law rules or principles.

Independent Services Agreement No. ISA-SD-2021 August 1, 2021 Page 4

Contractor shall not have the right to assign (directly or indirectly or by operation of law or otherwise) or delegate this Agreement or any of its rights or obligations hereunder without the prior written consent of Huntsman in each specific instance. Any attempted assignment or delegation without Huntsman’s consent shall be void ab initio. Acceptance by either party of any performance less than required by this Agreement shall not be deemed to be a waiver of the rights of such party to enforce all of the terms and conditions of this Agreement. No waiver of any provision of this Agreement shall be deemed to be or shall constitute a waiver of any other provision hereof, whether or not similar, nor shall any waiver constitute a continuing waiver. No amendments, modifications, alterations, or waivers of the terms of this Agreement shall be binding unless made in writing and executed by both of the parties hereto.

The provisions of this Agreement are severable. If any provision hereof should be void, voidable, or unenforceable under any applicable Laws, such void, voidable, or unenforceable provision shall not affect or invalidate any other provision of this Agreement, and this Agreement shall continue to govern the relative rights and duties of the parties as though the void, voidable, or unenforceable provision were not a part hereof. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more such counterparts have been signed by each of the parties and delivered to the other party. Counterparts and signatures transmitted by facsimile shall be valid as originals.

This Agreement and the other documents expressly referenced herein constitute the entire Agreement between the parties hereto with respect to the independent consulting, advisory, or support services provided by Contractor hereunder. Words used herein, regardless of the number or gender specifically used, shall be deemed and construed to include any other number (singular or plural) or any other gender (masculine, feminine, or neuter). As used in this Agreement: “person” shall mean an individual, corporation, company, partnership, association, trust, governmental authority or agency, or other entity or any combination thereof; “including” (and similar terms) shall mean “including without limitation” (and similarly for similar terms); “or” shall have the inclusive meaning represented by the phrase “and/or”; and “affiliate” shall mean, with respect to a specified person, any other person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified person.

Nature of Operations [Text Block]

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 (loss), 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, 2020 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, 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 operate 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; and

● the different capital structures.

​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 

Amendments to Accounts Receivable Securitization Programs

On July 1, 2021, we entered into amendments to 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”) that, among other things, extended the scheduled termination dates of our A/R Programs from April 2022 to July 2024. For additional information, see “Note 8. Debt—Direct and Subsidiary Debt—A/R Programs.”

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.

3. BUSINESS COMBINATIONS AND ACQUISITIONS

Acquisition of gaBRIEL Performance Products

On January 15, 2021, we completed the acquisition of Gabriel Performance Products, a North American specialty chemical manufacturer of specialty additives and epoxy curing agents for the coatings, adhesives, sealants and composite end-markets (“Gabriel Acquisition”), from funds affiliated with Audax Private Equity in an all-cash transaction of approximately $251 million, subject to customary closing adjustments. The purchase price was funded from available liquidity, and the acquired business is being integrated into our Advanced Materials segment. Transaction costs related to this acquisition were approximately nil and $2 million, respectively, for the three and nine months ended September 30, 2021 and were recorded in other operating income, net in our condensed consolidated statements of operations.

We accounted for the Gabriel Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The preliminary allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the Gabriel Acquisition	$	251
Cash	$	9
Accounts receivable		13
Inventories		26
Property, plant and equipment		23
Intangible assets		16
Goodwill		174
Accounts payable		(7	)
Accrued liabilities		(2	)
Deferred income taxes		(1	)
Total fair value of net assets acquired	$	251

The acquisition cost allocation is preliminary pending final determination of the fair value of assets acquired and liabilities assumed, including final valuation of certain liabilities, property, plant and equipment, intangible assets, leases and deferred taxes. Intangible assets acquired included in this preliminary allocation consist primarily of trademarks, technology and trade secrets. 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 in our Advanced Materials specialty portfolio and synergies. We expect that a portion of the estimated goodwill arising from the acquisition will be deductible for income tax purposes, but the amount is still being assessed. It is possible that material changes to this preliminary allocation of acquisition cost could occur.

The acquired business had revenues and net income of $81 million and $14 million, respectively, for the period from the date of acquisition to September 30, 2021.

Acquisition of CVC Thermoset Specialties

On May 18, 2020, we completed our acquisition of CVC Thermoset Specialties, a North American specialty chemical manufacturer serving the industrial composites, adhesives and coatings markets (“CVC Thermoset Specialties Acquisition”). We acquired the business for $304 million from Emerald Performance Materials LLC, which is majority owned by affiliates of American Securities LLC, in an all-cash transaction funded from available liquidity. The acquired business was integrated into our Advanced Materials segment. 

We accounted for the CVC Thermoset Specialties Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the CVC Thermoset Specialties Acquisition	$	304
Accounts receivable	$	12
Inventories		37
Property, plant and equipment		67
Intangible assets		117
Goodwill		120
Accounts payable		(7	)
Accrued liabilities		(1	)
Deferred income taxes		(41	)
Total fair value of net assets acquired	$	304

Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, which are predominantly being amortized over a period of 20 years. The goodwill recognized is attributable primarily to projected future profitable growth in our Advanced Materials specialty portfolio and synergies. None of the goodwill arising from the acquisition is deductible for income tax purposes. 

Acquisition of Icynene-Lapolla

On February 20, 2020, we completed our acquisition of Icynene-Lapolla, a leading North American manufacturer and distributor of spray polyurethane foam insulation systems for residential and commercial applications (“Icynene-Lapolla Acquisition”). We acquired the business from an affiliate of FFL Partners, LLC for $353 million in an all-cash transaction funded from available liquidity. The acquired business was integrated into our Polyurethanes segment. 

We accounted for the Icynene-Lapolla Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

Fair value of assets acquired and liabilities assumed:
Cash paid for the Icynene-Lapolla Acquisition	$	353
Cash	$	7
Accounts receivable		36
Inventories		32
Prepaid expenses and other current assets		2
Property, plant and equipment		9
Intangible assets		130
Goodwill		167
Other noncurrent assets		4
Accounts payable		(14	)
Accrued liabilities		(11	)
Deferred income taxes		(9	)
Total fair value of net assets acquired	$	353

As a result of the final valuation of the assets and liabilities, reallocations were made during the first quarter of 2021 in certain current asset and liability, property, plant and equipment, intangible asset, goodwill, other noncurrent assets and deferred tax balances. Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, which are predominantly being amortized over a period of 10 years. The goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets and synergies. None of the goodwill arising from the acquisition is deductible for income tax purposes.

S aLE of India-based do-it-Yourself consumer adhesives business

On November 3, 2020, we completed the sale of the India-based DIY business to Pidilite Industries Ltd. and received cash of approximately $257 million. Under the terms of the agreement, an earnout provision of up to approximately $28 million of additional cash was attainable if the business achieved, within 18 months, certain sales revenue targets in line with the DIY business' 2019 performance. The performance criteria of the earnout provision were satisfied in the second quarter of 2021, and we received the full payment of $28 million. As a result, we recognized an additional pretax gain of $28 million in the second quarter of 2021, which was recorded in gain on sale of India-based DIY business in our condensed consolidated statements of operations.

SaLE of Venator InterEST

On December 23, 2020, we completed the sale of approximately 42.4 million ordinary shares of Venator Materials PLC (“Venator”) and received approximately $99 million in cash. Subsequent to this sale of ordinary shares, we no longer account for our current remaining ownership interest in Venator as an equity method investment, but rather as an investment in equity securities that are marked to fair value with changes in fair value reported in earnings. Concurrently with the sale of ordinary shares, we entered into an option agreement, pursuant to which we granted an option to funds advised by SK Capital Partners, LP to purchase the remaining approximate 9.7 million ordinary shares we hold in Venator at $2.15 per share. The option will expire on June 23, 2023 and will not be exercisable so long as such exercise would result in a default or an "Event of Default" under Venator’s Term Loan Credit Agreement and Revolving Credit Agreement. We record this option at fair value with changes in fair value reported in earnings.

For the three months ended September 30, 2021 and 2020, we recorded net (losses) gains of $( 3) million and $6 million, respectively, and for the nine months ended  September 30, 2021 and 2020, we recorded net losses of $28 million and $100 million, respectively, to record our investment in Venator and related option to sell our remaining Venator shares at fair value. These net (losses) gains were recorded in “Fair value adjustments to Venator investment” in our condensed consolidated statements of operations.

Direct and Subsidiary Debt

Huntsman Corporation’s direct debt and guarantee obligations consist of a guarantee of certain indebtedness incurred from time to time to finance certain insurance premiums. 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 September 30, 2021 and December 31, 2020, the amount of debt issuance costs directly reducing the debt liability was $10 million and $9 million, respectively. We record the amortization of debt issuance costs as interest expense.

Term Loan Credit Facility

On September 24, 2019, Huntsman International entered into a 364-day term loan facility (the “2019 Term Loan”), pursuant to which Huntsman International borrowed an aggregate principal amount of €92 million (or $101 million equivalent). We used the net proceeds from the 2019 Term Loan to finance our acquisition of the 50% noncontrolling interest that we did not own in the Sasol-Huntsman maleic anhydride joint venture. On September 22, 2020, we repaid the 2019 Term Loan in full at maturity.

A/R Programs

Our 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.

On July 1, 2021, we entered into amendments to our A/R Programs that, among other things, extended the respective scheduled termination dates of our A/R Programs from April 2022 to July 2024.

On January 15, 2021, Huntsman International redeemed in full €445 million (approximately $541 million) in aggregate principal amount of our 5.125% senior notes due 2021 (“2021 Senior Notes”) at the redemption price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest to, but not including, the redemption date. In connection with this redemption, we incurred an incremental cash tax liability of approximately $15 million in the first quarter of 2021 related to foreign currency exchange gains.

On May 26, 2021, Huntsman International completed a $400 million offering of its 2031 Senior Notes. On June 23, 2021, Huntsman International applied the net proceeds from the offering, along with cash on hand, to redeem in full $400 million in aggregate principal amount of its 2022 Senior Notes and to pay accrued but unpaid interest of approximately $2 million. In addition, we paid redemption premiums and related fees and expenses of approximately $25 million and recognized a corresponding loss on early extinguishment of debt of $26 million in the second quarter of 2021.

The 2031 Senior Notes bear interest at 2.95% per year, payable semi‑annually on June 15 and December 15 of each year, and will mature on June 15, 2031. Huntsman International may redeem the 2031 Senior Notes in whole or in part at any time prior to March 15, 2031 at a price equal to 100% of the principal amount thereof plus a “make‑whole” premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption. Huntsman International may redeem the 2031 Senior Notes at any time in whole or from time to time in part, on or after March 15, 2031 at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of redemption. ​

Notes to Financial Statements

Derivative Instruments and Hedging Activities Disclosure [Text Block]

9. 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 September 30, 2021, we had approximately $178 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. 

We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of September 30, 2021, we have designated approximately €120 million (approximately $140 million) of euro-denominated debt as a hedge of our net investment. For the nine months ended September 30, 2021 and September 30, 2020, the amount recognized on the hedge of our net investment was a gain of $7 million and a loss of $31 million, respectively, and were recorded in other comprehensive income in our condensed consolidated statements of comprehensive income.​

10. FAIR VALUE

The fair values of financial instruments were as follows (dollars in millions):

	September 30, 2021						December 31, 2020
	Carrying			Estimated			Carrying			Estimated
	Value			Fair Value			Value			Fair Value

Long-term debt (including current portion)		(1,583	)		(1,755	)		(2,121	)		(2,334	)

The carrying amounts reported in the balance sheets of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments. Our investment in Venator is marked to fair value, which is obtained through market observable pricing using prevailing market prices (Level 1). Additionally, the estimated fair value of the option agreement related to the remaining ordinary shares we hold in Venator is based on a valuation technique using market observable inputs (Level 2). See “Note 4. Discontinued Operations and Business Dispositions—Sale of Venator Interest.” The fair values of non-qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices (Level 1). The estimated fair values of our long-term debt are based on quoted market prices for the identical liability when traded in an active market (Level 1). The fair value estimates presented herein are based on pertinent information available to management as of  September 30, 2021 and December 31, 2020. Although we are 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 September 30, 2021, and current estimates of fair value may differ significantly from the amounts presented herein.

During the nine months ended September 30, 2021, there were no instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3), and there were no gains or losses (realized and unrealized) included in earnings for instruments categorized as Level 3 within the fair value hierarchy.

Share Repurchase Program

On February 7, 2018 and on May 3, 2018, our Board of Directors collectively authorized us to repurchase up to an aggregate of $1 billion in shares of our common stock. The share repurchase program is supported by our free cash flow generation. Repurchases may be made through the open market, including through accelerated share repurchase programs, or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. Subsequent to the end of the first quarter of 2020, we suspended share repurchases under our existing share repurchase program in order to enhance our liquidity position in response to COVID-19. During the third quarter of 2021, we resumed the share repurchase program and repurchased 3,971,784 shares of our common stock for approximately $102 million, excluding commissions. 

Dividends on Common Stock

On April 28, 2021, our Board of Directors declared a $0.1875 per share cash dividend on our common stock. This represents a 15% increase from the previous dividend. During the quarters ended September 30, 2021 and  September 30, 2020, we paid $42 million and $36 million, respectively, or $0.1875 and $0.1625 per share, respectively, to common stockholders. During the quarters ended June 30, 2021 and June 30, 2020, we paid $41 million and $36 million, respectively, or $0.1875 and $0.1625 per share, respectively, to common stockholders. During the quarters ended and March 31, 2021 and March 31, 2020, we paid $36 million and $37 million, respectively, or $0.1625 per share each to common stockholders.

Legal Matters

We are a party to various 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 Loss Contingency Disclosure [Text Block]

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 nine months ended September 30, 2021 and 2020, our capital expenditures for EHS matters totaled $25 million and $17 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 $5 million and $4 million for environmental liabilities as of  September 30, 2021 and December 31, 2020, respectively. Of these amounts, $2 million and $1 million were classified as accrued liabilities in our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively, and $3 million was classified as other noncurrent liabilities in our condensed consolidated balance sheets as of both  September 30, 2021 and December 31, 2020. 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 Geismar, Louisiana facility is 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. At this time, we are unable to reasonably estimate our potential liabilities at this site.

Share-based Payment Arrangement [Text Block]

17. STOCK-BASED COMPENSATION PLANS

As of September 30, 2021, 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				Nine months
	ended				ended
	September 30,				September 30,
	2021		2020		2021		2020
Huntsman Corporation compensation cost	$	8	$	6	$	24	$	20
Huntsman International compensation cost		8		6		23		19

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 $3 million for the nine months ended September 30, 2021 and 2020, 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.

	Three months					Nine months
	ended					ended
	September 30,					September 30,
	2021(1)		2020			2021			2020
Dividend yield		NA		3.1	%		2.3	%		3.0	%
Expected volatility		NA		53.7	%		53.3	%		53.1	%
Risk-free interest rate		NA		0.4	%		0.7	%		1.4	%
Expected life of stock options granted during the period (in years)		NA		5.9			5.9			5.9

(1) During the three months ended  September 30, 2021, no stock options were granted.

A summary of stock option activity under the stock-based compensation plans as of September 30, 2021 and changes during the nine 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, 2021		4,815		$	20.37
Granted		304			28.58
Exercised		(697	)		17.44
Forfeited		(71	)		24.29
Outstanding at September 30, 2021		4,351			21.35		5.8	$	37
Exercisable at September 30, 2021		3,309			20.59		5.0		31

The weighted-average grant-date fair value of stock options granted during the nine months ended September 30, 2021 was $11.48 per option. As of September 30, 2021, there was $6 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 1.7 years.

The total intrinsic value of stock options exercised during the nine months ended September 30, 2021 and 2020 was approximately $8 million and $4 million, respectively. Cash received from stock options exercised during each of the nine months ended September 30, 2021 and 2020 was approximately $6 million and $2 million, respectively. The cash tax benefit from stock options exercised during each of the nine months ended September 30, 2021 and 2020 was approximately $2 million and $1 million, respectively.

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 nine months ended September 30, 2021 and 2020, the weighted-average expected volatility rate was 44.9% and 34.0%, respectively, and the weighted average risk-free interest rate was 0.2% and 1.4%, respectively. For the performance share unit awards granted in the nine months ended September 30, 2021 and 2020, 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 September 30, 2021 and changes during the nine 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, 2021		1,867			$	23.18		411		$	23.08
Granted		856				31.06		184			28.58
Vested		(521	)	(1)(2)		28.19		(189	)		24.55

Nonvested at September 30, 2021		2,185				25.07		386			24.92

(1) As of September 30, 2021, a total of 457,294 restricted stock units were vested but not yet issued, of which 30,438 vested during the nine months ended September 30, 2021. 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 110,542 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, 2020. During the nine months ended September 30, 2021, only 76,055 performance share unit awards with a grant date fair value of $41.93 were issued related to this vest due to the target performance criteria not being met.

As of September 30, 2021, there was $36 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the stock-based compensation plans. That cost is expected to be recognized over a weighted-average period of approximately 2.0 years. The value of share awards that vested during the nine months ended September 30, 2021 and 2020 was $18 million and $24 million, respectively.

Income Tax Disclosure [Text Block]

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 nine months ended September 30, 2021 and 2020, there was no tax benefit or expense recognized in connection with the net losses of $28 million and $100 million, respectively, on fair value adjustments to our Venator investment and related option to sell our remaining Venator shares recorded as part of non-operating income from continuing operations. As of December 31, 2019, we have recognized the portion of our Venator investment tax basis in excess of book that we ultimately expect to be able to utilize; therefore, no incremental tax benefit has been recognized on the year-to-date fair value losses incurred in 2020 or 2021. As a significant, unusual and non-operating item, these amounts were 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 $114 million and $9 million for the nine months ended September 30, 2021 and 2020, 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. 

Huntsman International

Huntsman International recorded income tax expense from continuing operations of $115 million and $9 million for the nine months ended September 30, 2021 and 2020, 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.

Earnings Per Share [Text Block]

19. EARNINGS PER SHARE

Basic earnings 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 earnings per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable 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 earnings per share is determined using the following information (in millions):

	Three months				Nine months

Additional stock-based awards of approximately 1.0 million and 3.8 million weighted average equivalent shares of stock were outstanding during the three months ended September 30, 2021 and 2020, respectively, and approximately 1.5 million and 6.1 million weighted average shares of stock were outstanding during the nine months ended September 30, 2021 and 2020, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the three and nine months ended September 30, 2021 and 2020 because the effect would be anti-dilutive.

Segment Reporting Disclosure [Text Block]

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.

The major products of each reportable operating segment are as follows:

Segment	Products
Polyurethanes	MDI, polyols, TPU and other polyurethane-related products
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 and toughening agents; epoxy, acrylic and polyurethane-based formulations; specialty nitrile latex, alkyd resins and carbon nano materials
Textile Effects	Textile chemicals and dyes

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. The adjusted EBITDA of our reportable operating segments excludes items that principally apply to our Company as a whole. The revenues and adjusted EBITDA from continuing operations for each of our reportable operating segments are as follows (dollars in millions):

(1) We use segment adjusted EBITDA as the measure of each segment’s profit or loss. We believe that segment adjusted EBITDA more accurately reflects what the chief operating decision maker uses to make decisions about resources to be allocated to the segments and assess their financial performance. Segment adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) EBITDA from discontinued operations; (c) fair value adjustments to Venator investment; (d) loss on early extinguishment of debt; (e) certain legal and other settlements and related income (expenses); (f) gain on sale of businesses/assets; (g) income from transition services arrangements related to the sale of our Chemical Intermediates Businesses to Indorama; (h) certain nonrecurring information technology project implementation costs; (i) amortization of pension and postretirement actuarial losses; (j) plant incident remediation costs; and (k) restructuring, impairment, plant closing and transition costs.

(2) Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets.

(3) Includes the gain on the sale of our Chemical Intermediates Businesses in 2020.

[1] Geographic information for revenues is based upon countries into which product is sold.

[2] We use segment adjusted EBITDA as the measure of each segment’s profit or loss. We believe that segment adjusted EBITDA more accurately reflects what the chief operating decision maker uses to make decisions about resources to be allocated to the segments and assess their financial performance. Segment adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments; (b) EBITDA from discontinued operations; (c) fair value adjustments to Venator investment; (d) loss on early extinguishment of debt; (e) certain legal and other settlements and related income (expenses); (f) gain on sale of businesses/assets; (g) income from transition services arrangements related to the sale of our Chemical Intermediates Businesses to Indorama; (h) certain nonrecurring information technology project implementation costs; (i) amortization of pension and postretirement actuarial losses; (j) plant incident remediation costs; and (k) restructuring, impairment, plant closing and transition costs.

[3] Includes the gain on the sale of our Chemical Intermediates Businesses in 2020.

[4] Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets.
