Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company calculates an effective income tax rate each quarter based upon forecasted annual income by jurisdiction, statutory tax rates and other tax-related items. The impact of discrete items is recognized in the interim period in which they occur. The effective tax rates for the three months ended March 31, 2013 and 2012 were 47.5% and 46.8%, respectively. The rates for both periods were unfavorably impacted by losses in foreign jurisdictions on which no tax benefit has been recognized and reductions to deferred tax assets for share-based compensation grants that expired with no corresponding tax benefit.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
