Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION These consolidated condensed financial statements include the accounts of Kulicke and Soffa Industries, Inc. and its subsidiaries (“we,” “us,” “our,” or the “Company”), with appropriate elimination of intercompany balances and transactions. The interim consolidated condensed financial statements are unaudited and, in management’s opinion, include all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of results for these interim periods. The interim consolidated condensed financial statements do not include all of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K/A for the fiscal year ended October 1, 2022 (the “2022 Annual Report”) filed with the Securities and Exchange Commission on August 8, 2023, which includes the Consolidated Balance Sheets as of October 1, 2022 and October 2, 2021, and the related Consolidated Statements of Operations, Statements of Comprehensive Income, Changes in Shareholders’ Equity and Cash Flows for each of the years in the three-year period ended October 1, 2022. The results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full year. Fiscal Year Each of the Company’s first three fiscal quarters end on the Saturday that is 13 weeks after the end of the immediately preceding fiscal quarter. The fourth quarter of each fiscal year ends on the Saturday closest to September 30. Fiscal 2023 quarters end on December 31, 2022, April 1, 2023, July 1, 2023 and September 30, 2023. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2022 quarters ended on January 1, 2022, April 2, 2022, July 2, 2022 and October 1, 2022. Nature of Business The Company designs, develops, manufactures and sells capital equipment and tools as well as services, maintains, repairs and upgrades equipment, all used to assemble semiconductor devices. The Company’s operating results depend upon the capital and operating expenditures of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry’s demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, solutions and services, including those sold or provided by the Company. These downturns and slowdowns have in the past adversely affected the Company’s operating results. The Company believes such volatility will continue to characterize the industry and the Company’s operations in the future. Use of Estimates The preparation of consolidated condensed financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated condensed financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory, carrying value and lives of fixed assets, goodwill and intangible assets, the valuation estimates and assessment of impairment and observable price adjustments, income taxes, equity-based compensation expense, and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company’s assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates. Due to the persistent macroeconomic headwinds, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of July 1, 2023. While there was no material impact to our consolidated condensed financial statements as of and for the quarter ended July 1, 2023, these estimates may change, as new events occur and additional information is obtained, including macroeconomic headwinds that could materially impact our consolidated condensed financial statements in future reporting periods. Significant Accounting Policies There have been no material changes to our significant accounting policies summarized in Note 1: Basis of Presentation to our Consolidated Financial Statements included in our 2022 Annual Report. Revision of Segment-Related Disclosures within the Previously Issued Consolidated Financial Statements During the third quarter of fiscal year 2023, in response to comment letters from and ongoing discussions with the staff of the SEC, the Company reconsidered the guidance under ASC 280, Segment Reporting, and determined that certain prior period conclusions about the Company’s operating and reportable segments were erroneous. As a result, the Company had incorrectly presented certain segment-related disclosures in the notes to our previously issued consolidated financial statements, included in our Annual Report on Form 10-K for the year ended October 1, 2022, originally filed with the SEC on November 17, 2022 (the “Original Form 10-K”). The Company has evaluated the materiality of the incorrect presentation of its segment-related disclosures in the notes to its consolidated financial statements and has concluded that it did not result in a material misstatement of the Company’s previously issued consolidated financial statements. In light of the changes to the Company’s operating and reportable segments, the Company has revised, in this Quarterly Report on Form 10-Q, the segment-related disclosures in Note 4: Goodwill and Intangible Assets and Note 15: Segment Information to update the prior period presentation. The effect of this revision has been reflected in all footnotes impacted by this revision. Recent Accounting Pronouncements Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosure by Business Entities about Government Assistance which aims at increasing the transparency of government assistance received by most business entities. The standard requires business entities to make annual disclosures about the nature of the transactions and the related accounting policy used to account for the transactions, the line items and applicable amounts on the balance sheet and income statement that are affected by the transactions, and significant terms and conditions of the transactions, including commitments and contingencies. If an entity omits any required disclosures because it is legally prohibited, it must describe the general nature of the information and indicate that the omitted disclosures are legally prohibited from being disclosed. This ASU is effective for fiscal years beginning after December 15, 2021, which for the Company is in fiscal 2023. The Company will include disclosures for material items with the filing of its Annual Report on Form 10-K for the year ending on September 30, 2023. Business Combinations In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with Topic 606: Revenue from Contracts with Customers. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. We elected for an early adoption of this ASU in fiscal year 2023. The adoption of this ASU did not have a material impact on our consolidated condensed financial statements.
