Income Tax Disclosure [Abstract]
Incomes Taxes	INCOME TAXES The provision for income taxes during the 2017 and 2016 periods is primarily comprised of current and deferred tax expense in profitable cost-plus foreign jurisdictions, accruals for tax contingencies in foreign jurisdictions and benefits for the reversal of previously recorded foreign tax contingencies due to the expiration of the applicable statutes of limitation. We recorded a benefit for the reversal of previously recorded foreign tax contingencies of $191 and $170 during the first six months of 2017 and 2016, respectively. As we do not believe that it is more likely than not that we will realize a benefit from our U.S. net deferred tax assets, including our U.S. net operating losses, we continue to provide a full valuation allowance against essentially all of those assets, therefore, we do not incur significant U.S. income tax expense or benefit. 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 June 30, 2017 and December 31, 2016, the amount of our uncertain tax positions was a liability of $1,435 and $1,419, respectively, and a reduction to deferred tax assets of $636 and $560, 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 $18 within the next twelve months due to the expiration of statutes of limitation in foreign jurisdictions. We recognize interest and penalties related to uncertain tax positions in income tax expense in our consolidated statements of operations. We adopted ASU 2016-09 on January 1, 2017. We have excess tax benefits for which a benefit could not be previously recognized of $485. Upon adoption, this balance was recognized and the impact was recorded to retained earnings, including any change to the valuation allowance as a result of the adoption. Due to the full valuation allowance on the U.S. net deferred tax assets, this change did not impact our financial position, results of operations or cash flows.

The provision for income taxes during the 2017 and 2016 periods is primarily comprised of current and deferred tax expense in profitable cost-plus foreign jurisdictions, accruals for tax contingencies in foreign jurisdictions and benefits for the reversal of previously recorded foreign tax contingencies due to the expiration of the applicable statutes of limitation.
