Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Contingencies From time to time, the Company is a party to litigation, claims and other contingencies, including environmental, regulatory and employee matters and examinations and investigations by governmental agencies, which arise in the ordinary course of business. The Company records a contingent liability when it is probable that a loss has been incurred and the amount of loss is reasonably estimable in accordance with ASC Topic 450, Contingencies, or other applicable accounting standards. As of April 2, 2022 and October 2, 2021, the Company had reserves of $31 million and $37 million, respectively, for environmental matters, warranty, litigation and other contingencies (excluding reserves for uncertain tax positions), which the Company believes are adequate. However, there can be no assurance that the Company's reserves will be sufficient to settle these contingencies. Such reserves are included in accrued liabilities and other long-term liabilities on the unaudited condensed consolidated balance sheets. Legal Proceedings Environmental Matters The Company is subject to various federal, state, local and foreign laws and regulations and administrative orders concerning environmental protection, including those addressing the discharge of pollutants into the environment, the management and disposal of hazardous substances, the cleanup of contaminated sites, the materials used in products, and the recycling, treatment and disposal of hazardous waste. As of April 2, 2022, the Company had been named in a lawsuit and several administrative orders alleging certain of its current and former sites contributed to groundwater contamination. One such order demands that the Company and other alleged defendants remediate groundwater contamination at four landfills located in Northern California to which the Company may have sent wastewater in the past. The Company is participating in a working group of other alleged defendants to better understand its potential exposure in this action and has reserved its estimated exposure for this matter as of April 2, 2022. However, there can be no assurance that the Company's reserve will ultimately be sufficient. In June 2008, the Company was named by the Orange County Water District in a suit alleging that its actions contributed to polluted groundwater managed by the plaintiff. The complaint seeks recovery of compensatory and other damages, as well as declaratory relief, for the payment of costs necessary to investigate, monitor, remediate, abate and contain contamination of groundwater within the plaintiff’s control. In April 2013, all claims against the Company were dismissed. The plaintiff appealed this dismissal and the appellate court reversed the judgment in August 2017, remanding the case back to the Superior Court for trial. The first phase of a multi-phase trial against the Company and several other defendants commenced in April 2021 and is expected to conclude in the third quarter of fiscal 2022. Subsequent trial phases, if necessary, likely would occur later in 2022 and 2023. The Company is contesting the plaintiff’s claims vigorously. Other Matters In October 2018, a contractor who had been retained by the Company through a third party temporary staffing agency filed a lawsuit against the Company in the Santa Clara County Superior Court on behalf of himself and all other similarly situated Company contractors and employees in California, alleging violations of California Labor Code provisions governing overtime, meal and rest periods, wages, wage statements and reimbursement of business expenses. The complaint sought certification of a class of all non-exempt employees. Although the Company continued to deny any wrongdoing, on November 19, 2020, the Company reached an agreement to resolve all claims, including claims under California's Private Attorneys General Act of 2004 (the “Settlement”), which also resulted in the dismissal of a suit alleging substantially similar claims filed in the Santa Clara County Superior Court in June 2021. The final amount of the judicially approved settlement was approximately $4 million and was paid during the first quarter of fiscal 2022. In December 2019, the Company sued a former customer, Dialight plc (“Dialight”), in the United States District Court for the Southern District of New York to collect approximately $10 million in unpaid accounts receivable and net obsolete inventory obligations. Later the same day, Dialight commenced its own action in the same court. Dialight’s complaint, which asserts claims for fraudulent inducement, breach of contract, and gross negligence/willful misconduct, alleges that the Company fraudulently misrepresented its capabilities to induce Dialight to enter into a Manufacturing Services Agreement (the “Dialight MSA”), and then breached its obligations contained in the Dialight MSA relating to quality, on-time delivery and supply chain management. Dialight seeks compensatory and punitive damages that it contends exceed $200 million, but which the Company believes are vastly overstated and are subject to a contractual limitation of liability that limits any Dialight recovery to less than $2 million. The Company continues to vigorously prosecute its claims against Dialight. Further, the Company strongly disagrees with Dialight’s allegations and is defending against them vigorously. No trial date has been set in this matter. For each of the pending matters noted above, the Company is unable to reasonably estimate a range of possible loss at this time. Other Contingencies During the three months ended April, 3, 2021, the Company received settlement payments of $5 million in connection with certain anti-trust class action matters. These payments are included in other income (expense), net in the condensed consolidated statements of income.
