Income Taxes	Note 4. Income Taxes For the three months ended March 31, 2012, income tax expense attributable to continuing operations was $23,970, representing an effective tax rate of 36%. The effective tax rate differs from the federal statutory rate of 35% due primarily to state income tax expense of $1,354, tax expense of $764 related to uncertain tax positions, including accrued interest, partially offset by a tax benefit of $2,015 resulting from a decrease in the valuation allowance with regard to certain local income tax credit carry forwards. For the three months ended March 31, 2011, income tax expense attributable to continuing operations was $23,136, representing an effective tax rate of 44%. The effective tax rate differs from the federal statutory rate of 35% due primarily to state income tax expense of $2,803, tax expense of $1,523 related to uncertain tax positions, including accrued interest and tax expense of $385 resulting from an increase in the valuation allowance with regard to certain local income tax credit carry forwards. At March 31, 2012, the Company had federal net operating loss carry forwards ("NOLs") of approximately $96,000, expiring on various dates from 2023 through 2025, and foreign tax credit carry forwards of approximately $14,800, expiring on various dates from 2014 through 2022. The Company has recorded a deferred tax asset related to $74,000 of such NOLs. A deferred tax asset has not been recorded for the remaining NOL of $22,000 as this portion relates to excess tax benefits that have not yet been realized (as determined on a 'with-and-without' approach), including 'windfall' deductions on share-based compensation awards and amortization of certain tax deductible goodwill. Upon realization as a reduction in tax liability, such excess tax benefits will be recorded as an increase to paid-in capital with regard to share-based compensation awards and as a decrease in goodwill with regard to certain tax deductible goodwill.
