Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	(11) Income Taxes The Company recognized a provision (benefit) for income taxes of $1,125, or 15.0% and $(884), or (14.3)% of income (loss) before income taxes, for federal, state and foreign income taxes for the three months ended June 30, 2013 and 2012, respectively. The increase in the tax provision as well as the effective tax rate was primarily due to generating income before income taxes in the current period compared to a loss before income taxes for the same period of 2012 as well as the impact of the decline in the performance of our U.S. operations. The Company recognized a provision for income taxes of $2,144, or 16.7% and $334, or 42.7% of income before income taxes, for federal, state and foreign income taxes for the six months ended June 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 six months ended June 30, 2013 compared to the same period for 2012 was primarily attributable to the improved performance of PST, which was partially offset by the decline in the performance of the North American operations.
