De Jaray, Perienne De Jaray and Darrell R. Oswald (collectively, the “Plaintiffs”) commenced an action against the Company and several unnamed defendants in the Multnomah County Circuit Court of the State of Oregon, in connection with the sale of certain products by the Company to the Plaintiffs in or around <em style="font: inherit;">2008.</em> The Plaintiffs alleged that we violated the Lanham Act, engaged in negligence, fraud, and breach of contract by failing to disclose to the Plaintiffs the export-controlled status of the subject parts. In <em style="font: inherit;"> January 2019, </em>we removed the action to the United States District Court for the District of Oregon (the “Court”). On <em style="font: inherit;"> May 24, 2023, </em>the Plaintiffs filed a <em style="font: inherit;">second</em> amended complaint, which added Apex-Micro Manufacturing Corporation as a plaintiff and removed the violation of the Lanham Act claim. The Plaintiffs sought damages of $180 million, punitive damages, and other remedies. On <em style="font: inherit;"> January 18, 2024, </em>the court dismissed the claims against the Company by Perienne De Jaray and Darrell R. Oswald. The trial for the remainder of the claims was held from <em style="font: inherit;"> January 30, 2024 </em>to <em style="font: inherit;"> February 15, 2024. </em>On <em style="font: inherit;"> February 13, 2024, </em>after both parties rested their cases and prior to the submission of the case to the jury, the Company filed a Rule <em class="GFJY4-DIN-com-rdg-thunderdome-client-resources-CssResource-html-element-highlighted" style="font: inherit;">50</em> motion for judgment as a matter of law as to all remaining claims due to insufficient evidence to support the claims. The Court granted the Company’s Rule <em class="GFJY4-DIN-com-rdg-thunderdome-client-resources-CssResource-html-element-highlighted" style="font: inherit;">50</em> motion in part and entered judgment in the Company’s favor as to all of Steven De Jaray’s claims and Apex-Micro Manufacturing Corporation’s negligence claims. On <em style="font: inherit;"> February 15, 2023, </em>the jury found that the Company was <em style="font: inherit;">not</em> liable for all outstanding claims and the presiding judge stated he would enter the judgment in favor of the Company.</p> <p style="font-family: Arial; font-size: 9pt; margin: 0pt; text-align: left;"> </p> <p style="font-family: Arial; font-size: 9pt; margin: 0pt; text-align: left;">From time to time, we are exposed to certain additional asserted and unasserted potential claims. We review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, we then accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and <em style="font: inherit;"> may </em>revise estimates.</p>
