Incomes Taxes	INCOME TAXES The benefit for income taxes recorded for the first quarter of 2012 and 2011 was primarily due to a benefit of $1,044 and $331, respectively, for the reversal of previously recorded tax contingencies due to the expiration of the applicable statutes of limitation, partially offset by current and deferred tax expense in profitable cost-plus foreign jurisdictions and accruals for tax contingencies in foreign jurisdictions. As of March 31, 2012, we continued to provide a full valuation allowance against essentially all of our U.S. and Canadian net deferred tax assets as we do not believe that it is more likely than not that we will realize a benefit from those assets. We have not recorded a valuation allowance against our other foreign net deferred tax assets as we believe that it is more likely than not that we will realize a benefit from those assets. As of March 31, 2012 and December 31, 2011, the amount of our uncertain tax positions was a liability of $2,203 and $3,105, respectively. A number of years may elapse before an uncertain tax position is resolved by settlement or statute of limitation. Settlement of any particular position could require the use of cash. If the uncertain tax positions we have accrued for are sustained by the taxing authorities in our favor, the reduction of the liability will reduce our effective tax rate. We reasonably expect reductions in the liability for unrecognized tax benefits and interest and penalties of approximately $762 within the next twelve months due to the expiration of statutes of limitation in foreign jurisdictions.
