Accounting Policies [Abstract] |
Use of Estimates | Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and may result in material effects on our operating results and financial position.
Principles of Consolidation | Principles of Consolidation. The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated.
Fiscal Year End | Fiscal Year End. Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year. When a 53-week year occurs, we include the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2022 and 2021 are both 52-week years. Fiscal 2022 will end on October 29, 2022. Fiscal 2021 ended on October 30, 2021. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
Redeemable Non-controlling Interest | Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as the temporary equity in our unaudited condensed consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We adjust the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recorded with corresponding adjustments against retained earnings.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements | Recently Adopted Accounting Pronouncements In December 2019, the FASB issued Accounting Standards Update (ASU) 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. We adopted the standard as of the beginning of fiscal 2022 on a prospective basis and the adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. We early adopted the standard in the second quarter of fiscal 2022 and the adoption had no material impact on our unaudited condensed consolidated financial statements for acquisitions completed in the first two quarters of fiscal 2022. The adoption of ASU 2021-08 resulted in the recognition of deferred revenue at amounts consistent with those recorded by the acquiree immediately before the acquisition date rather than at fair value for the business acquisition completed in the third quarter of fiscal 2022. See Note 4. Business Combinations for further information. Recently Issued Accounting Pronouncements In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03), which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. The standard will become effective for us beginning on November 1, 2024 and should be applied prospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our unaudited condensed consolidated financial statements.
