Income Taxes

NOTE 4—INCOME TAXES

Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because we have concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

United files a consolidated federal income tax return with UAL. Under an intercompany tax allocation policy, United computes, records and pays UAL for its own tax liability as if United were a separate company filing a separate return. In determining its own tax liabilities, United takes into account all tax credits or benefits generated and utilized as a separate company and it is compensated for the aforementioned tax benefits only if it would be able to use those benefits on a separate company basis.
