Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold. D erivatives and edging ctivities All derivatives, whether designated in hedging relationships or not, three not not E nvironmental xpenditures Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean-up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See “Note 21. E quity ethod nvestments We account for our equity investments where we own a non-controlling interest, but exercise significant influence, under the equity method of accounting. Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. . F oreign urrency ranslation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss. If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three Foreign currency transaction gains and losses are recorded in other operating income, net in our consolidated statements of operations and were a loss of $13 million, a gain of $18 million and a gain of $9 million for the years ended December 31, 2023, 2022 2021 I ncome axes 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 Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more likely than not not 19. I ntangible ssets and oodwill Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight-line method over the estimated useful lives or the life of the related agreement as follows: In years Patents and technology 5 - 30 Trademarks 9 - 30 Licenses and other agreements 5 - 15 Other intangibles 5 - 20 Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not third not During 2023 2022, I nventories Inventories are stated at the lower of cost or market, with cost determined using average cost, LIFO and first first L eases The determination of whether a contract is or contains a lease is performed at the lease inception date. Lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term, using incremental borrowing rates as the implicit rates are not 9. L egal osts We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred. N et ncome er hare ttributable to untsman orporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as potential dilutive securities. Diluted income per share is computed using the treasury stock method for all stock-based awards. In periods with reported loss from continuing operations attributable to Huntsman Corporation, all stock-based awards are generally deemed anti-dilutive and would be excluded from the calculation of diluted income per share from continuing operations, discontinued operations and net income regardless of whether there is income or loss from discontinued operations and net income. Basic and diluted income per share is determined using the following information (in millions): Year ended December 31, 2023 2022 2021 Numerator: (Loss) income from continuing operations attributable to Huntsman Corporation $ (17 ) $ 448 $ 996 Net income attributable to Huntsman Corporation $ 101 $ 460 $ 1,045 Denominator: Weighted average shares outstanding 177.4 201.0 219.2 Dilutive shares: Stock-based awards — 2.0 2.2 Total weighted average shares outstanding, including dilutive shares 177.4 203.0 221.4 Additional stock-based awards of 3.1 million, 1.1 million and 1.1 million weighted average equivalent shares of stock were outstanding during the years ended December 31, 2023, 2022 2021 not December 31, 2023, O ther oncurrent ssets Periodic maintenance and repairs applicable to major units of manufacturing facilities (a “turnaround”) are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround. P rinciples of onsolidation Our consolidated financial statements include the accounts of our wholly-owned and majority-owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated. P roperty, lant and quipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives or lease term as follows: In years Buildings 10 - 40 Plant and equipment 3 - 30 Furniture, fixtures and leasehold improvements 5 - 20 Interest expense capitalized as part of plant and equipment was $6 million, $7 million and $11 million for the years ended December 31, 2023, 2022 2021 Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired. R evenue ecognition We generate substantially all of our revenue through product sales in the open market and long-term supply agreements in which revenue is recognized at a point in time. At contract inception, we assess the goods and services, if any, promised in our contracts and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In substantially all cases, a contract has a single performance obligation to deliver a promised good to the customer. Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. We have elected to account for all shipping and handling activities as fulfillment costs. We have also elected to expense commissions when incurred as the amortization period of the commission asset that we would have otherwise recognized is less than one The amount of consideration we receive and revenue we recognize is based upon the terms stated in the sales contract, which may not one one not not 17. S ecuritization of ccounts eceivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities (“SPE”) in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in U.S. dollars, euros and British pounds. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14. S tock ased ompensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 23. U E 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.

Environmental Cost, Expense Policy [Policy Text Block]	E nvironmental xpenditures Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean-up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See “Note 21.
Equity Method Investments [Policy Text Block]	E quity ethod nvestments We account for our equity investments where we own a non-controlling interest, but exercise significant influence, under the equity method of accounting. Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. .
Foreign Currency Transactions and Translations Policy [Policy Text Block]	F oreign urrency ranslation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss.

Income Tax, Policy [Policy Text Block]	I ncome axes 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 Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

Lessee, Leases [Policy Text Block]	L eases The determination of whether a contract is or contains a lease is performed at the lease inception date. Lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term, using incremental borrowing rates as the implicit rates are not 9.
Legal Costs, Policy [Policy Text Block]	L egal osts We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.
Earnings Per Share, Policy [Policy Text Block]	N et ncome er hare ttributable to untsman orporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as potential dilutive securities. Diluted income per share is computed using the treasury stock method for all stock-based awards. In periods with reported loss from continuing operations attributable to Huntsman Corporation, all stock-based awards are generally deemed anti-dilutive and would be excluded from the calculation of diluted income per share from continuing operations, discontinued operations and net income regardless of whether there is income or loss from discontinued operations and net income. Basic and diluted income per share is determined using the following information (in millions): Year ended December 31, 2023 2022 2021 Numerator: (Loss) income from continuing operations attributable to Huntsman Corporation $ (17 ) $ 448 $ 996 Net income attributable to Huntsman Corporation $ 101 $ 460 $ 1,045 Denominator: Weighted average shares outstanding 177.4 201.0 219.2 Dilutive shares: Stock-based awards — 2.0 2.2 Total weighted average shares outstanding, including dilutive shares 177.4 203.0 221.4 Additional stock-based awards of 3.1 million, 1.1 million and 1.1 million weighted average equivalent shares of stock were outstanding during the years ended December 31, 2023, 2022 2021 not December 31, 2023,
Other Noncurrent Assets [Policy Text Block]	O ther oncurrent ssets Periodic maintenance and repairs applicable to major units of manufacturing facilities (a “turnaround”) are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround.
Consolidation, Policy [Policy Text Block]	P rinciples of onsolidation Our consolidated financial statements include the accounts of our wholly-owned and majority-owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated.

Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired.
Revenue from Contract with Customer [Policy Text Block]	R evenue ecognition We generate substantially all of our revenue through product sales in the open market and long-term supply agreements in which revenue is recognized at a point in time. At contract inception, we assess the goods and services, if any, promised in our contracts and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In substantially all cases, a contract has a single performance obligation to deliver a promised good to the customer. Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. We have elected to account for all shipping and handling activities as fulfillment costs. We have also elected to expense commissions when incurred as the amortization period of the commission asset that we would have otherwise recognized is less than one The amount of consideration we receive and revenue we recognize is based upon the terms stated in the sales contract, which may not one one not not 17.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block]	S ecuritization of ccounts eceivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities (“SPE”) in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in U.S. dollars, euros and British pounds. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14.
Share-Based Payment Arrangement [Policy Text Block]	S tock ased ompensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 23.
Use of Estimates, Policy [Policy Text Block]	U E 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.
