Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies and Basis of Presentation We have prepared the accompanying condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The condensed consolidated financial statements are unaudited but, in management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our quarterly results. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended October 31, 2022 as filed with the SEC on December 12, 2022 (our Annual Report). 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 condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position. Principles of Consolidation. The condensed consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. 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 2023 and 2022 are both 52-week years. Fiscal 2023 will end on October 28, 2023. Fiscal 2022 ended on October 29, 2022. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end. Comparability. Certain reclassifications have been made to the prior period's condensed consolidated financial statements to conform to the current year presentation. The reclassifications did not have a material impact on the prior period's condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows. Segment Reporting. Effective in the first quarter of fiscal 2023, we realigned our organizational structure to evaluate the results of our Design IP business separately. Our Chief Operating Decision Maker (CODM), our Chief Executive Officer (CEO), now regularly reviews disaggregated segment information, assesses performance against our key growth strategies and allocates resources based on this new organizational structure. As a result, effective in the first quarter of fiscal 2023, we changed our reportable segments from two reportable segments to the following three reportable segments: (1) Design Automation, which includes EDA tools, system integration solutions and other associated revenue categories, (2) Design IP, which includes IP products, and (3) Software Integrity, which includes a comprehensive solution for building integrity—security, quality and compliance testing—into the customers' software development lifecycle and supply chain. As such, prior period reportable segment results and related disclosures have been reclassified to reflect our current reportable segments. Goodwill. As a result of the change to our reportable segments, we reassessed our reporting units for the evaluation of goodwill during the first quarter of fiscal 2023. Prior to this change, our reporting units were determined to be the same as reportable segments for the purpose of goodwill impairment assessment. Our reassessment determined that we now have three reporting units, which are the same as our reportable segments. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by us. The carrying amount of goodwill at each reporting unit is tested for impairment annually on the first day of the fourth fiscal quarter, or more frequently if facts and circumstances warrant a review. We perform either a qualitative or quantitative assessment for goodwill impairment test. When a quantitative goodwill impairment assessment is performed, we use an income approach based on discounted cash flow analysis, a market approach based on market multiples, or a combination of both. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment loss is recorded for the difference. The change in reporting units was considered a triggering event, indicating a test for goodwill impairment was required before and after the change in reporting units. We performed those impairment tests, which did not result in the identification of an impairment loss as of January 31, 2023. If assumptions or estimates with respect to our future performance vary from what is expected, including but not limited to those assumptions relating to inflationary pressure on costs and geopolitical uncertainties, this may impact the impairment analysis and could reduce the underlying cash flows used to estimate fair values and result in a decline in fair value that may trigger future impairment charges. Significant Accounting Policies. There have been no material changes to our significant accounting policies included in our Annual Report. Recently Issued Accounting Pronouncements In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 will be applied prospectively. Early adoption is permitted. Any future impact from the adoption of this guidance will depend on the facts and circumstances of future transactions.
