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.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. The Company's management assesses available positive and negative evidence regarding the realizability of its deferred tax assets, and records a valuation allowance when it is more likely than not that all or a portion of the deferred tax assets will not be realized. To form a conclusion, management considers positive evidence in the form of reversing temporary differences, projections of future taxable income and tax planning strategies, and negative evidence such as recent history of losses. Although the Company was no longer in a three-year cumulative loss position at the end of 2011, management determined that the size and frequency of financial losses in recent years and the uncertainty associated with projecting future taxable income supported the conclusion that the valuation allowance was still needed on net deferred assets. If UAL achieves significant profitability in 2012, then management will evaluate whether its recent history of profitability constitutes sufficient positive evidence to support a reversal of a portion, or all, of the remaining valuation allowance.
