Income Taxes [Abstract]
Income Taxes	(11) Income Taxes The Company adjusts its effective tax rate each quarter based on the estimated annual effective tax rate, as required. The Company also records the 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. In addition, jurisdictions with a projected loss for the year where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. The Company recognized a provision for income taxes of $1,016, or 15.6% and $383, or 39.4% of income before income taxes, for federal, state and foreign income taxes for the three months ended September 30, 2013 and 2012, respectively. The increase in the tax provision was primarily due to higher income before income taxes in the current period compared to the same period for 2012. The decrease in the effective tax rate for the three months ended September 30, 2013 compared to the same period for 2012 was primarily attributable to the improved performance of PST and our European operations, which was partially offset by a decline in the performance of our North American operations. The Company recognized a provision for income taxes of $3,160, or 16.3% and $717, or 40.9% of income before income taxes, for federal, state and foreign income taxes for the nine months ended September 30, 2013 and 2012, respectively. The increase in the tax provision was primarily due to higher income before income taxes compared to the same period in 2012. The decrease in the effective tax rate for the nine months ended September 30, 2013 compared to the same period for 2012 was primarily attributable to the improved performance of PST and our European operations, which was partially offset by a decline in the performance of our North American operations.

(11) Income Taxes

The Company adjusts its effective tax rate each quarter based on the estimated annual effective tax rate, as required. The Company also records the 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. In addition, jurisdictions with a projected loss for the year where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

The Company recognized a provision for income taxes of $1,016, or 15.6% and $383, or 39.4% of income before income taxes, for federal, state and foreign income taxes for the three months ended September 30, 2013 and 2012, respectively.
