16. 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 three months ended March 31, 2015 and 2014, for unrecognized tax benefits that impact tax expense, we recorded a net decrease in unrecognized tax benefits and a corresponding income tax benefit of $9 million, primarily in Asia, and a net increase in unrecognized benefits and a corresponding income tax expense of $4 million, respectively. Additional increases and decreases in unrecognized tax benefits were offset by cash settlements or decreases in net deferred tax assets and, therefore, did not affect income tax expense.

Huntsman Corporation

        We recorded income tax expense of $2 million and $36 million for the three months ended March 31, 2015 and 2014, 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. Notably, we continue to earn a significant portion of our pre-tax income in the United States with an approximate 35% federal and state blended effective tax rate.

Huntsman International

        Huntsman International recorded income tax expense of $3 million and $37 million for the three months ended March 31, 2015 and 2014, 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. Notably, we continue to earn a significant portion of our pre-tax income in the United States with an approximate 35% federal and state blended effective tax rate.
