Income Taxes [Abstract]
Income Taxes	(12) Income Taxes The Company computes its consolidated income tax provision each quarter based on a projected annual effective tax rate, as required. The Company is required to reduce deferred tax assets by a valuation allowance if, based on all available evidence, it is considered more likely than not that some portion or all of the benefit of the deferred tax assets will not be realized in future periods. When the Company maintains a valuation allowance in a particular jurisdiction, no net tax expense will typically be provided on the income for that jurisdiction. Jurisdictions with projected income that maintain a valuation allowance typically will form part of the projected annual effective tax rate calculation discussed above. However, jurisdictions with a projected loss for the year that maintain a valuation allowance are excluded from the projected annual effective income tax rate calculation. Instead, the income tax for these jurisdictions is computed separately. The Company also records the income tax impact of certain discrete, unusual or infrequently occurring items including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. As a result, the Company’s actual effective income tax rate during a particular quarter can vary significantly based upon the jurisdictional mix and timing of actual earnings compared to projected annual earnings, permanent items, earnings for those jurisdictions that maintain a valuation allowance, tax associated with jurisdictions excluded from the projected annual effective income tax rate calculation and discrete items. The Company recognized an income tax provision (benefit) of $(381) and $90 from continuing operations for federal, state and foreign income taxes for the three months ended June 30, 2015 and 2014, respectively. The effective tax rate decreased to (6.4)% in the second quarter of 2015 from 0.3% in the second quarter of 2014. The decrease in the income tax expense and the effective tax rate for the three months ended June 30, 2015 compared to the same period for 2014 was primarily due to the improved earnings of the U.S. operations and reduced earnings of the European operations, which were partially offset by the smaller operating loss of PST. The Company recognized a provision (benefit) for income taxes of $(234) and $385 for federal, state and foreign income taxes for the six months ended June 30, 2015 and 2014, respectively.

(12) Income Taxes

The Company computes its consolidated income tax provision each quarter based on a projected annual effective tax rate, as required. The Company is required to reduce deferred tax assets by a valuation allowance if, based on all available evidence, it is considered more likely than not that some portion or all of the benefit of the deferred tax assets will not be realized in future periods.

When the Company maintains a valuation allowance in a particular jurisdiction, no net tax expense will typically be provided on the income for that jurisdiction. Jurisdictions with projected income that maintain a valuation allowance typically will form part of the projected annual effective tax rate calculation discussed above. However, jurisdictions with a projected loss for the year that maintain a valuation allowance are excluded from the projected annual effective income tax rate calculation. Instead, the income tax for these jurisdictions is computed separately.

The Company also records the income tax impact of certain discrete, unusual or infrequently occurring items including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur.

As a result, the Company’s actual effective income tax rate during a particular quarter can vary significantly based upon the jurisdictional mix and timing of actual earnings compared to projected annual earnings, permanent items, earnings for those jurisdictions that maintain a valuation allowance, tax associated with jurisdictions excluded from the projected annual effective income tax rate calculation and discrete items.
