Income Tax Disclosure [Abstract]
Income taxes	Income taxes The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognized valuation allowances of $2,147 and $1,946 against its deferred tax assets related to certain tax jurisdictions as of September 30, 2013 and December 31, 2012, respectively. During the three and nine months ended September 30, 2013, the Company recorded additional valuation allowances of $185 and $201, respectively, against deferred tax assets related to our continuing operations. During the three and nine months ended September 30, 2012, the Company recorded additional valuation allowances of $163 and $543, respectively, against deferred tax assets related to our continuing operations. To the extent the Company generates sufficient taxable income in the future to utilize the tax benefits of the net deferred tax assets on which a valuation allowance is recorded, the effective tax rate may decrease as the valuation allowance is reversed. As of September 30, 2013, the Company is no longer able to carry back its tax net operating losses; therefore, to the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on net deferred tax assets and income tax benefit would be adversely affected. For the three and nine months ended September 30, 2013, the Company’s effective income tax rate including discontinued operations and other discrete items was (58.9)% and (20.9)%, respectively, which varied from the federal statutory rate of 35% primarily due to non-deductibility of the termination fee of $9,000 related to our management services agreement with Gores and certain capitalized costs. For the three and nine months ended September 30, 2012, the Company’s effective income tax rate including discontinued operations and other discrete items was 121.5% and 35.5%, respectively, which varied from the federal statutory rate of 35% primarily due to state income tax expense and valuation allowance. The effective income tax rate on continuing operations for the three months ended September 30, 2013 was (55.0)% compared to an effective income tax rate on continuing operations of 61.3% for the three months ended September 30, 2012. The effective income tax rate on continuing operations for the nine months ended September 30, 2013 was (15.7)% compared to an effective income tax rate on continuing operations of 35.5% for the nine months ended September 30, 2012. The decrease in the tax rates for the comparative three-month and nine-month periods is primarily due to the domestic manufacturing deduction tax benefit, which was not available in the prior year due to the Company’s tax operating loss position, changes to the valuation allowance against the Company’s deferred tax assets, the non-deductibility of the termination fee related to our management services agreement with Gores and the capitalization of certain costs. The Company has no material uncertain tax positions as of September 30, 2013 and December 31, 2012.

Income taxes

The Company evaluates its deferred tax assets quarterly to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, the Company considers both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company recognized valuation allowances of $2,147 and $1,946 against its deferred tax assets related to certain tax jurisdictions as of September 30, 2013 and December 31, 2012, respectively.

During the three and nine months ended September 30, 2013, the Company recorded additional valuation allowances of $185 and $201, respectively, against deferred tax assets related to our continuing operations. During the three and nine months ended September 30, 2012, the Company recorded additional valuation allowances of $163 and $543, respectively, against deferred tax assets related to our continuing operations. To the extent the Company generates sufficient taxable income in the future to utilize the tax benefits of the net deferred tax assets on which a valuation allowance is recorded, the effective tax rate may decrease as the valuation allowance is reversed. As of September 30, 2013, the Company is no longer able to carry back its tax net operating losses; therefore, to the extent the Company generates future tax net operating losses, the Company may be required to increase the valuation allowance on net deferred tax assets and income tax benefit would be adversely affected.

For the three and nine months ended September 30, 2013, the Company’s effective income tax rate including discontinued operations and other discrete items was (58.9)% and (20.9)%, respectively, which varied from the federal statutory rate of 35% primarily due to non-deductibility of the termination fee of $9,000 related to our management services agreement with Gores and certain capitalized costs. For the three and nine months ended September 30, 2012, the Company’s effective income tax rate including discontinued operations and other discrete items was 121.5% and 35.5%, respectively, which varied from the federal statutory rate of 35% primarily due to state income tax expense and valuation allowance.

The effective income tax rate on continuing operations for the three months ended September 30, 2013 was (55.0)% compared to an effective income tax rate on continuing operations of 61.3% for the three months ended September 30, 2012. The effective income tax rate on continuing operations for the nine months ended September 30, 2013 was (15.7)% compared to an effective income tax rate on continuing operations of 35.5% for the nine months ended September 30, 2012. The decrease in the tax rates for the comparative three-month and nine-month periods is primarily due to the domestic manufacturing deduction tax benefit, which was not available in the prior year due to the Company’s tax operating loss position, changes to the valuation allowance against the Company’s deferred tax assets, the non-deductibility of the termination fee related to our management services agreement with Gores and the capitalization of certain costs.
