Income Taxes [Abstract]
Income Taxes	(10) 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 projected earnings. The Company recognized a provision for income taxes of $430, or 46.7% and $1,019, or 19.2% of income before income taxes, for federal, state and foreign income taxes for the three months ended March 31, 2014 and 2013, respectively. The decrease in the tax provision was primarily due to lower income before income taxes in the current period compared to the same period for 2013 primarily due to the loss incurred by PST. The reduction in income tax expense was partially offset by discrete tax items related to certain foreign operations recorded during the current period. The increase in the effective tax rate for the three months ended March 31, 2014 compared to the same period for 2013 was primarily attributable to the negative impact of recognizing a tax benefit on the PST loss at a local tax rate lower than the Company’s statutory rate as well as the impact of the discrete tax items referenced above.

(10) 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 projected earnings.

The Company recognized a provision for income taxes of $430, or 46.7% and $1,019, or 19.2% of income before income taxes, for federal, state and foreign income taxes for the three months ended March 31, 2014 and 2013, respectively. The decrease in the tax provision was primarily due to lower income before income taxes in the current period compared to the same period for 2013 primarily due to the loss incurred by PST. The reduction in income tax expense was partially offset by discrete tax items related to certain foreign operations recorded during the current period. The increase in the effective tax rate for the three months ended March 31, 2014 compared to the same period for 2013 was primarily attributable to the negative impact of recognizing a tax benefit on the PST loss at a local tax rate lower than the Company’s statutory rate as well as the impact of the discrete tax items referenced above.
