Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended June 30, 2016, we reported an effective tax rate of 45.3%, which was higher than the 35% U.S. federal statutory rate due primarily to the tax expense on unremitted foreign earnings not considered permanently reinvested, the impact of valuation allowances on the losses of certain foreign subsidiaries, and changes in state tax rates. For the six months ended June 30, 2016, we reported an effective tax rate of 45.2%, which was higher than the 35% U.S. federal statutory rate due primarily to the tax expense on unremitted foreign earnings not considered permanently reinvested and the impact of valuation allowances on the losses of certain foreign subsidiaries. For the three months ended June 30, 2015, we reported an effective tax rate of 108.1%, which was higher than the 35% U.S. federal statutory rate due primarily to the expiration of the look-through rule, tax expenses on unremitted foreign earnings not considered permanently reinvested, and the impact of valuation allowances on the losses of certain foreign subsidiaries. For the six months ended June 30, 2015, we reported a loss before income taxes and an effective tax rate benefit of (79.8)%, which was different than the 35% U.S. federal statutory rate due primarily to these same reasons. Effective January 1, 2015, the look-through rule under Subpart F of the U.S. Internal Revenue Code noted above expired but was reinstated in December 2015 retroactive to January 1, 2015. Subpart F requires U.S. corporate shareholders to recognize current U.S. taxable income from passive income, including earnings of certain foreign subsidiaries, regardless of whether that income is remitted to the United States. The look-through rule of Subpart F grants an exception for any passive income of certain foreign subsidiaries that is attributable to an active business. When the look-through exception is not in effect, we are required to accrue a tax liability for those foreign earnings as if those earnings were distributed to the United States. Consequently, in the first quarter of 2015, we recorded the additional tax expense we would have incurred in the absence of the look-through rule. The total amount of unrecognized tax benefits was $2.0 million as of June 30, 2016, and $1.9 million as of December 31, 2015. These same amounts would affect the effective tax rate, if recognized. The accrued interest payable for taxes was $0.1 million as of June 30, 2016 and December 31, 2015. There was no significant liability for tax penalties as of June 30, 2016 or December 31, 2015. We are regularly audited by federal, state and foreign taxing authorities. Given the uncertainties inherent in the audit process, it is reasonably possible that certain audits could result in a significant increase or decrease in the total amounts of unrecognized tax benefits. An estimate of the range of the increase or decrease in unrecognized tax benefits due to audit results cannot be made at this time. Tax years 2008 and forward remain open for examination in some state and foreign jurisdictions, and tax years 2012 and forward remain open for examination for U.S. federal purposes.
