Management’s Discussion & Analysis

Income Tax Expense and Accruals

Our annual tax rate is based on our income, statutory tax rates and tax planning opportunities available to us in the various jurisdictions in which we operate. Significant judgment is required in determining our annual tax rate and in evaluating our tax positions. We establish reserves when, despite our belief that our tax return positions are fully supportable, we believe that certain positions are subject to challenge and that we may not succeed. We adjust these reserves, as well as the related interest, in light of changing facts and circumstances, such as the progress of a tax audit.

An estimated effective tax rate for a year is applied to our quarterly operating results. In the event there is a significant or unusual item recognized in our quarterly operating results, the tax attributable to that item is separately calculated and recorded at the same time as that item. We consider the tax adjustments from the resolution of prior year tax matters to be such items.

Tax law requires items to be included in our tax returns at different times than the items are reflected in our financial statements. As a result, our annual tax rate reflected in our financial statements is different than that reported in our tax returns (our cash tax rate). Some of these differences are permanent, such as expenses that are not deductible in our tax return, and some differences reverse over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in our tax returns in future years for which we have already recorded the tax benefit in our income statement. We establish valuation allowances for our deferred tax assets if, based on the available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax liabilities generally represent tax expense recognized in our financial statements for which payment has been deferred, or expense for which we have already taken a deduction in our tax return but have not yet recognized as expense in our financial statements.

In 2008, our annual tax rate was 26.8% compared to 25.9% in 2007 as discussed in “Other Consolidated Results.” The tax rate in 2008 increased 0.9 percentage points primarily due to the absence of the tax benefits recognized in the prior year related to the favorable resolution of certain foreign tax matters, partially offset by lower taxes on foreign results in the current year. In 2009, our annual tax rate is expected to be approximately the same as 2008.
