Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We recognized total income tax expense from continuing operations of $150 million for the three months ended March 31, 2016, compared to income tax expense of $103 million for the same period in 2015. The increase in income tax expense for the three months ended March 31, 2016, compared to the same period in 2015, was primarily driven by tax attributable to pre-tax earnings and a nonrecurring benefit from the release of our valuation allowance on capital loss carryforwards utilized against 2015 capital gains. 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 Annual Report on Form 10-K for the year ended December 31, 2015, 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 $150 million for the three months ended March 31, 2016, compared to income tax expense of $103 million for the same period in 2015. The increase in income tax expense for the three months ended March 31, 2016, compared to the same period in 2015, was primarily driven by tax attributable to pre-tax earnings and a nonrecurring benefit from the release of our valuation allowance on capital loss carryforwards utilized against 2015 capital gains.

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 Annual Report on Form 10-K for the year ended December 31, 2015, 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.
