Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We recognized total income tax expense from continuing operations of $103 million during the three months ended March 31, 2015, compared to income tax expense of $94 million for the same period in 2014. The increase in income tax expense for the three months ended March 31, 2015, compared to the same period in 2014, was driven primarily by a reduction in tax credits. As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credits and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards. It is reasonably possible the unrecognized tax benefits disclosed in our 2014 Annual Report on Form 10-K will decrease by up to $180 million over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction as anticipated.

Income Taxes

We recognized total income tax expense from continuing operations of $103 million during the three months ended March 31, 2015, compared to income tax expense of $94 million for the same period in 2014. The increase in income tax expense for the three months ended March 31, 2015, compared to the same period in 2014, was driven primarily by a reduction in tax credits.

As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credits and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards.

It is reasonably possible the unrecognized tax benefits disclosed in our 2014 Annual Report on Form 10-K will decrease by up to $180 million over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction as anticipated.
