|Income Tax Disclosure [Abstract]|
The net tax expense of $5 million for the three months ended July 30, 2016 consisted of state and foreign tax expenses of $4 million, $1 million of expense related to the deferred tax asset change arising from the tax amortization of indefinite-lived intangible assets and $2 million of expense relating to other comprehensive income, offset by a $2 million benefit for state audit settlements.
The net tax expense of $4 million for the six months ended July 30, 2016 consisted of state and foreign tax expenses of $7 million and $3 million of expense related to the deferred tax asset change arising from the tax amortization of indefinite-lived intangible assets, offset by net tax benefits of $4 million to adjust the valuation allowance and $2 million for state audit settlements.
As of July 30, 2016, we have approximately $2.6 billion of net operating losses (NOLs) available for U.S. federal income tax purposes, which expire in 2032 through 2034 and $62 million of tax credit carryforwards that expire at various dates through 2035. For these NOL and tax credit carryforwards a net deferred tax asset of $78 million has been recorded, net of a valuation allowance of $818 million. A valuation allowance of $239 million fully offsets the deferred tax assets resulting from the state NOL carryforwards that expire at various dates through 2034. In assessing the need for the valuation allowance, we considered both positive and negative evidence related to the likelihood of realization of the deferred tax assets. As a result of our periodic assessment, our estimate of the realization of deferred tax assets is solely based on the future reversals of existing taxable temporary differences and tax planning strategies that we would make use of to accelerate taxable income to utilize expiring NOL and tax credit carryforwards. Accordingly, in the second quarter and first six months of 2016, the valuation allowance was increased by $19 million and $32 million, respectively, to offset the net deferred tax assets created in those periods relating primarily to the increase in NOL carryforwards.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
