Basis of Presentation We operate on a 52- or 53-week fiscal year ending on the Sunday closest to October 31 in a 52-week year and the first Sunday in November in a 53-week year. Our fiscal year ending October 31, 2021 (“fiscal year 2021”) is a 52-week fiscal year. The first quarter of our fiscal year 2021 ended on January 31, 2021, the second quarter ends on May 2, 2021 and the third quarter ends on August 1, 2021. Our fiscal year ended November 1, 2020 (“fiscal year 2020”) was also a 52-week fiscal year. The accompanying condensed consolidated financial statements include the accounts of Broadcom and its subsidiaries, and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information. The financial information included herein is unaudited, and reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the results for the periods presented. The November 1, 2020 condensed consolidated balance sheet data were derived from Broadcom’s audited consolidated financial statements included in its Annual Report on Form 10-K for fiscal year 2020 as filed with the Securities and Exchange Commission. All intercompany transactions and balances have been eliminated in consolidation. The operating results for the fiscal quarter ended January 31, 2021 are not necessarily indicative of the results that may be expected for fiscal year 2021, or for any other future period. Significant Accounting Policies Use of estimates. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The inputs into certain of these estimates and assumptions include the consideration of the economic impact of the COVID-19 pandemic. Actual results could differ materially from these estimates, and such differences could affect the results of operations reported in future periods. As the impact of the COVID-19 pandemic continues to develop, many of these estimates could require increased judgment and carry a higher degree of variability and volatility, and may change materially in future periods. Reclassifications. Certain reclassifications have been made to the prior period condensed consolidated statement of cash flows to conform to the current period presentation. These reclassifications had no impact on previously reported net cash activities.
