Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company provides a valuation allowance for deferred tax assets when it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The Company’s deferred tax asset valuation allowance increased from $4.1 billion as of December 31, 2011 to $4.8 billion as of June 30, 2012, including the impact of comprehensive income for the six months ended June 30, 2012 and changes from other adjustments. Under current accounting rules, the Company is required to consider all items (including items recorded in other comprehensive income) in determining the amount of tax benefit that results from a loss from continuing operations and that should be allocated to continuing operations. The Company generally does not record any such tax benefit allocation in interim reporting periods as the Company concluded the potential benefit is not considered realizable because the change in the pension liability, a material component of other comprehensive income, is determined annually. Thus, any such interim tax benefit allocation may subsequently be subject to reversal.
