Basis of Presentation [Abstract] |
Basis of Presentation | Unless the context otherwise requires, the use of the terms “Best Buy,” “we,” “us” and “our” in these Notes to Condensed Consolidated Financial Statements refers to Best Buy Co., Inc. and, as applicable, its consolidated subsidiaries. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments necessary for a fair presentation as prescribed by accounting principles generally accepted in the United States (“GAAP”). All adjustments were comprised of normal recurring adjustments, except as noted in these Notes to Condensed Consolidated Financial Statements. Historically, we have generated a large proportion of our revenue and earnings in the fiscal fourth quarter, which includes the majority of the holiday shopping season in the U.S., Canada and Mexico. Due to the seasonal nature of our business, interim results are not necessarily indicative of results for the entire fiscal year. The interim financial statements and the related notes included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended February 1, 2020. The first nine months of fiscal 2021 and fiscal 2020 included 39 weeks. In order to align our fiscal reporting periods and comply with statutory filing requirements, we consolidate the financial results of our Mexico operations on a one-month lag. Our policy is to accelerate recording the effect of events occurring in the lag period that significantly affect our condensed consolidated financial statements. Other than as disclosed in Note 2, Restructuring Charges, no such events were identified for the reported periods. In preparing the accompanying condensed consolidated financial statements, we evaluated the period from October 31, 2020, through the date the financial statements were issued for material subsequent events requiring recognition or disclosure. No such events were identified for the reported periods.
