Earnings Per Share [Text Block]	19. ​ 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 (loss) income per share is determined using the following information (in millions): Three months ended March 31, 2024 2023 Numerator: (Loss) income from continuing operations attributable to Huntsman Corporation $ (30 ) $ 31 Net (loss) income attributable to Huntsman Corporation $ (37 ) $ 153 Denominator: Weighted average shares outstanding 171.8 182.7 Dilutive shares: Stock-based awards — 1.7 Total weighted average shares outstanding, including dilutive shares 171.8 184.4 ​ ​ Additional stock-based awards of approximately 2.7 million and 1.5 million weighted average equivalent shares of stock were outstanding during the three March 31, 2024 2023 not three March 31, 2024 ​
