Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of presentation | The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by Cadence Design Systems, Inc. (“Cadence”) without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations.
Use of estimates | Preparation of the condensed consolidated 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 disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.
Recently adopted accounting standards | In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update 2019-12, “Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes, eliminates certain exceptions within Accounting Standards Codification 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Cadence adopted the standard on January 3, 2021, the first day of fiscal 2021. The adoption of this standard did not impact Cadence’s condensed consolidated financial statements for the period ended October 2, 2021.
Fair value of financial instruments | Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: •Level 1 – Quoted prices for identical instruments in active markets; •Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and •Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the nine months ended October 2, 2021.
Contingencies | At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates.
