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 $1,961 and $1,946 against its deferred tax assets related to certain tax jurisdictions as of June 30, 2013 and December 31, 2012, respectively. During the three and six months ended June 30, 2013, the Company recorded additional valuation allowances of $9 and $15 against deferred tax assets related to our continuing operations. During the three and six months ended June 30, 2012, the Company released valuation allowances of $59 and recorded additional valuation allowances of $370, 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 June 30, 2013, the Company is no longer able to carry back our 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 six months ended June 30, 2013, the Company’s effective income tax rate including discontinuing operations and other discrete items was 34.5% and 26.0%, respectively, which varied from the federal statutory rate of 35% primarily due to the capitalization of certain costs. For the three and six months ended June 30, 2012, the Company’s effective income tax rate including discontinuing operations and other discrete items was 37.8% and 34.5%, 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 June 30, 2013 was 33.9% compared to an effective income tax rate on continuing operations of 38.0% for the three months ended June 30, 2012. The effective income tax rate on continuing operations for the six months ended June 30, 2013 was 28.2% compared to an effective income tax rate on continuing operations of 34.5% for the six months ended June 30, 2012. The decrease in the tax rates for the comparative three month period and six month period are 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, and the capitalization of certain costs. The Company has no material uncertain tax positions as of June 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 $1,961 and $1,946 against its deferred tax assets related to certain tax jurisdictions as of June 30, 2013 and December 31, 2012, respectively.

During the three and six months ended June 30, 2013, the Company recorded additional valuation allowances of $9 and $15 against deferred tax assets related to our continuing operations. During the three and six months ended June 30, 2012, the Company released valuation allowances of $59 and recorded additional valuation allowances of $370, 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 June 30, 2013, the Company is no longer able to carry back our 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 six months ended June 30, 2013, the Company’s effective income tax rate including discontinuing operations and other discrete items was 34.5% and 26.0%, respectively, which varied from the federal statutory rate of 35% primarily due to the capitalization of certain costs. For the three and six months ended June 30, 2012, the Company’s effective income tax rate including discontinuing operations and other discrete items was 37.8% and 34.5%, 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 June 30, 2013 was 33.9% compared to an effective income tax rate on continuing operations of 38.0% for the three months ended June 30, 2012. The effective income tax rate on continuing operations for the six months ended June 30, 2013 was 28.2% compared to an effective income tax rate on continuing operations of 34.5% for the six months ended June 30, 2012.
