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 for the fiscal year ended September 30, 2023 (the “2023 Annual Report”) filed with the Securities and Exchange Commission on November 16, 2023, which includes the Consolidated Balance Sheets as of September 30, 2023 and October 1, 2022, 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 September 30, 2023. 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 2024 quarters end on December 30, 2023, March 30, 2024, June 29, 2024 and September 28, 2024. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2023 quarters ended on December 31, 2022, April 1, 2023, July 1, 2023 and September 30, 2023. 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, accrual for customer credit programs, 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. In light of 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 December 30, 2023. While there was no material impact from macroeconomic headwinds to our consolidated condensed financial statements as of and for the quarter ended December 30, 2023, these estimates may change, as new events occur and additional information is obtained, including factors related to these 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 2023 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 the staff of the Securities and Exchange Commission (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 14: 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 Disclosure Improvements In October 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU aligns the requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements of a variety of Codification Topics. They will also allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. This ASU will become effective for each amendment on the date on which the SEC removes the related disclosure from its regulations. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments in the ASU enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity's overall performance and assess potential future cash flows. This ASU will be effective for the Company's fiscal year 2025, and interim periods within the fiscal years beginning after the Company’s fiscal year 2026. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Income Taxes In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvement to Income Tax Disclosures. The amendments in this update are intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This ASU will be effective for the Company's fiscal year 2026. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.
