Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | NOTE 1. Basis of Presentation The accompanying interim unaudited Condensed Consolidated Financial Statements have been prepared by Onto Innovation Inc. (together with its consolidated subsidiaries, unless otherwise specified or suggested by the context, the “Company,” “Onto Innovation,” “we,” “our” or “us”) and in the opinion of management reflect all adjustments, consisting of normal recurring accruals, necessary for their fair presentation in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual amounts could differ materially from reported amounts. The interim results for the three and six months ended July 1, 2023 are not necessarily indicative of results to be expected for the entire year or any future periods. This interim financial information should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Form 10-K”) filed with the Securities and Exchange Commission (“SEC”) on February 24, 2023. The accompanying Condensed Consolidated Balance Sheet at December 31, 2022 has been derived from the audited consolidated financial statements included in the 2022 Form 10-K. The Company operates on a 52- or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal year ending December 30, 2023 (“fiscal year 2023”) is a 52-week fiscal year. The first quarter of the Company’s fiscal year 2023 ended on April 1, 2023, the second quarter ended on July 1, 2023 and the third quarter ends on September 30, 2023. Our fiscal year ended December 31, 2022 was a 52-week fiscal year. The second quarter of the fiscal year ended December 31, 2022 ended on July 2, 2022. Use of Estimates The preparation of 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 as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates made by management include excess and obsolete inventory, fair value of assets acquired and liabilities assumed in a business combination, recoverability and useful lives of property, plant and equipment and identifiable intangible assets, recoverability of goodwill, recoverability of deferred tax assets, allowance for credit losses, liabilities for product warranty, contingencies, including litigation reserves and share-based payments and liabilities for tax uncertainties. Actual results could differ from those estimates. These estimates and assumptions are based on historical experience and on various other factors which the Company believes to be reasonable under the circumstances. The Company may engage third-party valuation specialists to assist with estimates related to the valuation of financial instruments, assets and stock awards associated with various contractual arrangements. Such estimates often require the selection of appropriate valuation methodologies and significant judgment. Actual results could differ from these estimates under different assumptions or circumstances and such differences could be material. Adoption of Accounting Standards There have been no recent accounting pronouncements or changes in accounting pronouncements during the three and six months ended July 1, 2023, as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, that are of significance, or potential significance to the Company.
