|Income Tax Disclosure [Abstract]|
The net tax benefit of $8 million for the three months ended November 3, 2018 consisted of federal, state and foreign tax benefits of $2 million, a $2 million benefit relating to other comprehensive income and a $5 million benefit due to the release of valuation allowance, offset by $1 million of expense related to the deferred tax asset change arising from the tax amortization of indefinite-lived intangible assets.
The net tax benefit of $4 million for the nine months ended November 3, 2018 consisted of federal, state and foreign tax expenses of $3 million, $3 million of expense related to the deferred tax asset change arising from the tax amortization of indefinite-lived intangible assets and $1 million of net tax expense resulting from enacted state law changes, offset by a $5 million benefit relating to other comprehensive income, a $5 million benefit due to the release of valuation allowance and a net tax benefit of $1 million resulting from state audit settlements.
As of November 3, 2018, we have approximately $2.4 billion of net operating losses (NOLs) available for U.S. federal income tax purposes, which largely expire in 2032 through 2034 and $60 million of tax credit carryforwards that expire at various dates through 2037. A valuation allowance of $578 million (restated for the tax effects of revenue recognition) fully offsets the federal deferred tax assets resulting from the NOL and tax credit carryforwards that expire at various dates through 2037. A valuation allowance of $257 million fully offsets the deferred tax assets resulting from the state NOL carryforwards that expire at various dates through 2037. 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 three and nine months ended November 3, 2018, the valuation allowance was increased by $35 million and $69 million, respectively, to offset the net deferred tax assets created in the quarter 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.
