Income Taxes

Estimates and judgments are used in the calculation of certain tax liabilities and in the determination of the recoverability of certain deferred tax assets. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. We regularly evaluate the recoverability of our deferred tax assets and provide valuation allowances to offset portions of deferred tax assets due to uncertainty surrounding the future realization of such deferred tax assets. Valuation allowances are based on historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences, and the implementation of tax-planning strategies. We adjust the valuation allowance in the period we determine it is more likely than not that deferred tax assets will or will not be realized. If a change in circumstances results in a change in our ability to realize our deferred tax assets, our tax provision would increase in the period when the change in circumstances occurs.

Accounting for our income taxes also requires significant judgment in the evaluation of our uncertain tax positions and in the calculation of our provision for income taxes. Effective January 1, 2007, we adopted a standard related to accounting for uncertainty in income taxes, which contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate available evidence to determine if it appears more likely than not that an uncertain tax position will be sustained on an audit by a taxing authority, based solely on the technical merits of the tax position. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settling the uncertain tax position.

Although we believe we have adequately reserved for our uncertain tax positions, the ultimate outcome of these tax matters may differ from our expectations. We adjust our reserves in light of changing facts and circumstances, such as the completion of a tax audit, expiration of a statute of limitations, the refinement of an estimate, and interest accruals associated with uncertain tax positions until they are resolved. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.

During the fourth quarter of 2009, we completed a restructuring of certain of our subsidiaries, a consequence of which was the elimination of a deferred tax liability of $12.7 million, which was reflected as a benefit in our tax provision for the three months ended December 31, 2009.

Our future effective tax rates could be affected by changes in our deferred tax assets or liabilities, the valuation of our uncertain tax positions, or by changes in tax laws, regulations, accounting principles, or interpretations thereof.

Income Taxes

We file a consolidated federal income tax return. Deferred income taxes have been provided for temporary differences between the recognition of revenue and expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities and their reported amounts in the financial statements.
