Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim income tax reporting, we are required to estimate our annual effective tax rate and apply it to year-to-date pre-tax ordinary income/loss excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. For the three months ended March 31, 2013 we recorded income tax expense of $0.4 million. The effective income tax rate for the three months ended March 31, 2013 was (2.6) percent, compared with (16.5) percent in the same period last year. The effective rate change was primarily due to a full valuation allowance on U.S. deferred tax assets, lower withholding tax expense and the mix of taxable income (loss) by country. The effective income tax rate for the three months ended March 31, 2013 differs from the U.S. federal statutory rate of 35 percent primarily due to the full valuation allowance on U.S. deferred tax assets and the effects of foreign tax rate differential. We conduct business globally. As a result, we file income tax returns in multiple jurisdictions and are subject to review by various U.S and foreign taxing authorities. Our U.S. federal income tax returns for 2010 and 2011 are subject to examination by the Internal Revenue Service (IRS). With few exceptions, we are no longer subject to examination by foreign tax jurisdictions or state and city tax jurisdictions for years before 2006. In the event that we have determined not to file tax returns with a particular state or city, all years remain subject to examination by the tax jurisdiction. We accrue for the effects of uncertain tax positions and the related potential penalties and interest. Our liability related to uncertain tax positions, which is presented within the other liabilities line on our Condensed Consolidated Balance Sheets and which includes interest and penalties, was $4.6 million and $4.7 million as of March 31, 2013 and December 31, 2012, respectively. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain of our unrecognized tax positions will increase or decrease during the next twelve months; however it is not possible to reasonably estimate the effect upon the unrecognized tax benefits at this time.

For interim income tax reporting, we are required to estimate our annual effective tax rate and apply it to year-to-date pre-tax ordinary income/loss excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded.

For the three months ended March 31, 2013 we recorded income tax expense of $0.4 million. The effective income tax rate for the three months ended March 31, 2013 was (2.6) percent, compared with (16.5) percent in the same period last year. The effective rate change was primarily due to a full valuation allowance on U.S. deferred tax assets, lower withholding tax expense and the mix of taxable income (loss) by country. The effective income tax rate for the three months ended March 31, 2013 differs from the U.S. federal statutory rate of 35 percent primarily due to the full valuation allowance on U.S. deferred tax assets and the effects of foreign tax rate differential.
