Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, the Company has condensed or omitted certain information and footnote disclosures it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its unaudited condensed consolidated balance sheets, results of operations, comprehensive income and cash flows. The Company’s 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 Synopsys’ Annual Report on Form 10-K for the fiscal year ended October 31, 2016 as filed with the SEC on December 12, 2016. 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 the Company’s operating results and financial position. Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated. Fiscal Year End. The Company’s fiscal year ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, the Company has a 53-week year. Fiscal 2017 and 2016 are both 52-week years. The second fiscal quarters of fiscal 2017 and 2016 ended on April 29, 2017 and April 30, 2016, respectively, and the prior fiscal year ended on October 29, 2016. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
