Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes (Restated) Our effective income tax rate for continuing operations for the three and six months ended June 30, 2011 was an expense of $1.6 million, or 38.6%, and $1.6 million, or 254.3%, as compared to a benefit of $2.7 million, or 6.3%, and $2.1 million, or 4.9%, for the prior-year periods. For interim period reporting in the Form 10-Q filed on August 9, 2011, we measured income tax expense using an estimated annual effective tax rate. With the additional expenses reflected in this Form 10-Q/A, we believe applying the actual year-to-date effective tax rate for the six months ended June 30, 2011 is the best estimate of the annual effective tax rate. Our tax rate differs from the statutory rate of 35.0% due to the effects of permanent items and the recording of a valuation allowance against a portion of our deferred tax assets generated in the current year. It is reasonably possible that the total amount of unrecognized tax benefits may increase by approximately $0.5 million to $2.0 million during the next twelve months.
