Income Taxes	3 Months Ended
	Mar. 31, 2012
Income Taxes	(11) Income Taxes The Company recognized a provision for income taxes of $1,218 or 17.5% of income before income taxes and $677 or 20.2% of income before income taxes, for federal, state and foreign income taxes for the three months ended March 31, 2012 and 2011, respectively. The decrease in the effective tax rate for the three months ended March 31, 2012 compared to the same period for 2011 was attributable to the improved financial performance of the U.S. operations for which there is no income tax provision due to a full valuation allowance and the consolidation of PST which has a lower effective tax rate.
