Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate for the three months ended July 31, 2020 was 15.9 percent, as compared to 10.2 percent for the three months ended July 26, 2019. The increase in the effective tax rate for the three months ended July 31, 2020, as compared to the corresponding period in the prior fiscal year, was primarily due to the impact of certain tax adjustments, debt tender premium and other charges in the prior year, and year-over-year changes in operational results by jurisdiction. Certain Tax Adjustments During the three months ended July 31, 2020, the net cost from certain tax adjustments of $4 million, recognized in income tax provision in the consolidated statements of income, included the following: •A benefit of $3 million associated with the finalization of an intercompany sale of intellectual property and the establishment of a deferred tax asset. The cumulative amount of deferred tax benefit previously recognized from intercompany intellectual property transactions and recorded as Certain Tax Adjustments is $1.5 billion. The corresponding deferred tax assets will be amortized over a period of approximately 20 years. •A cost of $7 million associated with the amortization of the previously established deferred tax assets from intercompany intellectual property transactions. During the three months ended July 26, 2019, the net benefit from certain tax adjustments of $30 million, recognized in income tax provision in the consolidated statements of income, included the following: •A net benefit of $30 million related to U.S. Treasury’s issuance of certain Final Regulations associated with U.S. Tax Reform. The primary impact of these regulations resulted in the Company re-establishing its permanently reinvested assertion on certain foreign earnings and reversing the previously accrued tax liability. This benefit was partially offset by additional tax associated with a previously executed internal reorganization of certain foreign subsidiaries. At both July 31, 2020 and April 24, 2020, the Company's gross unrecognized tax benefits were $1.9 billion. In addition, the Company had accrued gross interest and penalties of $241 million at July 31, 2020. If all the Company’s unrecognized tax benefits were recognized, approximately $1.8 billion would impact the Company’s effective tax rate. At July 31, 2020 and April 24, 2020, the amount of the Company's gross unrecognized tax benefits recorded as a noncurrent liability within accrued income taxes on the consolidated balance sheets was $934 million and $911 million, respectively. The Company recognizes interest and penalties related to income tax matters within income tax provision in the consolidated statements of income and records the liability within either current or noncurrent accrued income taxes on the consolidated balance sheets. Refer to Note 16 to the consolidated financial statements for additional information regarding the status of current tax audits and proceedings.
