Indemnification Contingencies The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology. The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $189.0 million. There are some licensing agreements in place that do not specify indemnification limits. As of September 30, 2023, the Company had not recorded any liabilities related to these indemnification obligations and the Company believes that any amounts that it may be required to pay under these agreements in the future will not have a material adverse effect on its financial position, cash flows or results of operations. Warranty Costs and Product Liabilities The Company accrues for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, the Company has experienced a low rate of payments on product claims. Although the Company cannot predict the likelihood or amount of any future claims, the Company does not believe these claims will have a material adverse effect on its financial condition, results of operations or liquidity. Legal Matters In the ordinary course of the Company's business, it is exposed to various legal actions as a result of contracts, product liability, customer claims, pricing or royalty disputes with customers and licensees, governmental investigations and other matters. The Company is involved in a limited number of these legal actions, both as plaintiff and defendant, with respect to the foregoing types of matters. Consequently, the Company could incur uninsured liability in any of these legal actions. The Company also periodically receives notifications from various third parties alleging infringement of patents or other intellectual property rights, or from customers requesting reimbursement for various costs. With respect to pending legal actions to which the Company is a party and other claims, although the outcomes are generally not determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. Litigation, governmental investigations and disputes relating to the semiconductor industry are not uncommon, and the Company is, from time to time, subject to such litigation, governmental investigations and disputes. As a result, no assurances can be given with respect to the extent or outcome of any such litigation, governmental investigations or disputes in the future. The Company accrues for claims and contingencies when losses become probable and reasonably estimable. As of the end of each applicable reporting period, the Company reviews each of its matters and, where it is probable that a liability has been or will be incurred, the Company accrues for all probable and reasonably estimable losses. Where the Company can reasonably estimate a range of losses it may incur regarding such a matter, the Company records an accrual for the amount within the range that constitutes its best estimate. If the Company can reasonably estimate a range but no amount within the range appears to be a better estimate than any other, the Company uses the amount that is the low end of such range. As of September 30, 2023, the Company's estimate of the aggregate potential liability for legal matters that is possible but not probable is approximately $150.0 million in excess of amounts accrued. As a result of its acquisition of Atmel, which closed April 4, 2016, the Company became involved with the following legal matter: Individual Labor Actions by former LFR Employees. In June 2010, Atmel Rousset sold its wafer manufacturing business in Rousset, France to LFoundry GmbH (LF), the German parent of LFoundry Rousset (LFR). LFR then leased the Atmel Rousset facility to conduct the manufacture of wafers. More than three years later, LFR became insolvent and later liquidated. In the wake of LFR's insolvency and liquidation, over 500 former employees of LFR filed individual labor actions against Atmel Rousset in a French labor court, and in 2019 a French labor court dismissed all of the employees’ claims against Atmel Rousset. In 2020, the Plaintiffs filed appeals with the Court of Appeals requesting reconsideration of the earlier dismissals. In December 2022, the Court of Appeals dismissed these appeals and held that there had been no co-employment of the plaintiffs by Atmel Rousset and LFoundry Rousset. However, in 2017 these same claims were filed by this same group of employees in a regional court in France against Microchip Technology Incorporated and Atmel Corporation. The Company, and the other defendant entities, believe that each of these actions is entirely devoid of merit, and, further, that any assertion by any of the Claimants of a co-employment relationship with any of these entities is based substantially on the same specious arguments that the Paris Commercial Court summarily rejected in 2014 in related proceedings. The defendant entities therefore intend to defend vigorously against each of these claims. Additionally, complaints have been filed in a regional court in France on behalf of the same group of employees against Microchip Technology Rousset, Atmel Switzerland Sarl, Atmel Corporation and Microchip Technology Incorporated alleging that the sale of the Atmel Rousset production unit to LF was fraudulent and should be voided. These claims are specious and the defendant entities therefore intend to defend vigorously against these claims.
