Income Tax Disclosure [Abstract]  
Income Taxes
Income Taxes 
Income tax expense from continuing operations was impacted primarily due to certain losses from continuing operations being generated in jurisdictions where no tax benefit can be recognized for the three and six months ended June 30, 2012 compared with the three and six months ended June 30, 2011. These losses with no tax benefit resulted in income tax expense despite an overall loss from continuing operations for the six months ended June 30, 2012 and impacted effective income tax rates for all periods in 2012.
An income tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on technical merits. The unrecognized income tax benefit at June 30, 2012 was $37.0 million including interest and penalties.  Within the next twelve months, it is reasonably possible that up to $4.5 million of unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
