Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rates for continuing operations of (37.6)% and (54.1)%, respectively, for the three months ended June 30, 2013 and 2012 and the effective tax rates for continuing operations of (39.1)% and 404.0%, respectively, for the six months ended June 30, 2013 and 2012 were determined using an estimated annual effective tax rate and after considering any discrete items for such periods. Due to a valuation allowance against our U.S. deferred tax assets, the effective tax rate for the three and six months ended June 30, 2013 and 2012 does not include the benefit of the current year U.S. tax loss. Income tax expense for the three and six months ended June 30, 2013 and 2012 primarily reflects income tax expense in foreign jurisdictions.

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.
