Accounting Policies [Abstract] |
Summary of Significant Policies | Note 1—Summary of Significant Accounting Policies Description of Business Costco Wholesale Corporation (Costco or the Company), a Washington corporation, and its subsidiaries operate membership warehouses based on the concept that offering members low prices on a limited selection of nationally-branded and private-label products in a wide range of merchandise categories will produce high sales volumes and rapid inventory turnover. For the period ended May 8, 2022, Costco operated 829 warehouses worldwide: 573 in the United States (U.S.) located in 46 states, Washington, D.C., and Puerto Rico, 105 in Canada, 40 in Mexico, 30 in Japan, 29 in the United Kingdom (U.K.), 16 in Korea, 14 in Taiwan, 13 in Australia, four in Spain, two each in France and China, and one in Iceland. The Company operates e-commerce websites in the U.S., Canada, Mexico, U.K., Korea, Taiwan, Japan, and Australia. Basis of Presentation The condensed consolidated financial statements include the accounts of Costco, its wholly-owned subsidiaries, and subsidiaries in which it has a controlling interest. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. All material inter-company transactions among the Company and its consolidated subsidiaries have been eliminated in consolidation. The Company’s net income excludes income attributable to the noncontrolling interest in Taiwan. Unless otherwise noted, references to net income relate to net income attributable to Costco. These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial reporting pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). While these statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the fiscal year ended August 29, 2021. Fiscal Year End The Company operates on a 52/53 week fiscal year basis, with the fiscal year ending on the Sunday closest to August 31. Fiscal 2022 is a 52-week year ending on August 28, 2022. References to the third quarter of 2022 and 2021 relate to the 12-week fiscal quarters ended May 8, 2022 and May 9, 2021, respectively. References to the first thirty-six weeks of 2022 and 2021 relate to the 36 weeks ended May 8, 2022 and May 9, 2021, respectively. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions take into account historical and forward-looking factors that the Company believes are reasonable. Actual results could differ from those estimates and assumptions. Property and Equipment, Net The Company capitalizes certain computer software and costs incurred in developing or obtaining software. The Company recognized a $118 write-off of certain information technology assets, which was recorded in the first quarter of 2022, in selling, general and administrative expenses. Reclassification Reclassifications were made to our third quarter and first thirty-six weeks of 2021 condensed consolidated statements of income to conform with current period presentation.
