Income Taxes	6 Months Ended
Jun. 30, 2015
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In the second quarter of 2015, we recorded income tax expense of approximately $1 million from foreign, state and local jurisdictions. In the United States, we are in a net operating loss carryforward position and our deferred income tax assets are subject to a valuation allowance. Therefore, any domestic income or loss before income taxes does not generate a corresponding income tax expense or benefit. In the six months ended June 30, 2015, we had income tax benefit of approximately $1 million. The income tax benefit for the six months reflects audit closures in certain foreign jurisdictions offset slightly by state and local jurisdiction tax expense. As of June 30, 2015, we had federal net operating loss, or NOL, carryforwards of approximately $1.833 billion that are available to offset future federal taxable income and will expire in the years 2026 through 2032, none of which are subject to Internal Revenue Code limitations under Section 382. In addition, as of that date, we had federal Alternative Minimum Tax, or AMT, credit carryforwards of approximately $46 million that are available to reduce future regular federal income taxes over an indefinite period. In order to fully realize these U.S. federal net deferred tax assets, taxable income of approximately $1.963 billion would need to be generated during the period before their expiration. In addition, we have federal foreign tax credit carryforwards of $8 million that will expire if unused in 2015. As of June 30, 2015, we had a gross deferred tax asset related to our state NOLs and tax credit carryforwards of $242 million, of which $1 million will expire in 2015. The remainder will expire if unused in years 2016 through 2033. We also had NOL and tax credit carryforwards in various foreign jurisdictions in the amount of $1 million as of June 30, 2015, against which we have maintained a valuation allowance. During periods prior to 2015, we established a valuation allowance against our deferred tax assets totaling $1.023 billion. During the first six months of 2015, we recorded a decrease in the valuation allowance against our deferred tax assets of $43 million resulting in a deferred tax asset valuation allowance of $980 million as of June 30, 2015. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more-likely-than-not standard, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. During 2015, we may realize a four year cumulative accounting profit in the U.S. If this occurs, we will also consider all other positive and negative evidence to determine the realizability of our deferred tax assets and the need for a full, or partial, valuation allowance. Any reversal of our valuation allowance will favorably impact our results of operations in the period of reversal. The Internal Revenue Code imposes limitations on a corporation’s ability to utilize NOLs if it experiences an “ownership change.” In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. If we were to experience an ownership change, utilization of our NOLs would be subject to an annual limitation determined by multiplying the market value of our outstanding shares of stock at the time of the ownership change by the applicable long-term tax-exempt rate, which was 2.50% for June 2015. Any unused annual limitation may be carried over to later years within the allowed NOL carryforward period. The amount of the limitation may, under certain circumstances, be increased or decreased by built-in gains or losses held by us at the time of the change that are recognized in the five-year period after the change. Many states have similar limitations. If an ownership change had occurred as of June 30, 2015, our annual U.S. federal NOL utilization would have been limited to approximately $101 million per year.
