BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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. However, Cadence believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. These condensed consolidated financial statements are meant to be, and should be, read in conjunction with the consolidated financial statements and the notes thereto included in Cadence’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the "Annual Report"). The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect all adjustments (which include only normal, recurring adjustments and those items discussed in these notes) that are, in the opinion of management, necessary to state fairly the results of operations, cash flows and financial position for the periods and dates presented. The results for such periods are not necessarily indicative of the results to be expected for the full fiscal year or other periods. Certain prior period balances have been reclassified to conform to the current period presentation. Management has evaluated subsequent events through the issuance date of the unaudited condensed consolidated financial statements. Fiscal Year End Cadence’s fiscal year end is December 31, and its fiscal quarters end on March 31, June 30, and September 30. 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. Actual results could differ from those estimates. Recently Adopted Accounting Standards Segment Reporting In November 2023, the Financial Accounting Standards Board (“FASB”), issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” intended to improve reportable segment disclosure requirements, primarily through enhanced annual and interim disclosures for significant segment expenses. Cadence adopted this ASU retrospectively during fiscal 2024 for its Annual Report. For interim disclosures required by this ASU, see Note 15 in the notes to condensed consolidated financial statements. New Accounting Standards Not Yet Adopted Income Taxes In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. This standard is effective for fiscal years beginning after December 15, 2024, and may be applied on a retrospective or prospective basis. Cadence plans to adopt this standard in connection with its annual report for fiscal 2025 and is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. Income Statement - Expense Disaggregation Disclosure In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures,” which requires additional disclosure of certain costs and expenses in the notes to the financial statements. The updated standard is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted and will be applied prospectively with the option for retrospective application. Cadence is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.
