Legal Proceedings [Abstract] |
Legal Proceedings | Legal Proceedings In the ordinary course of business, there are various claims, lawsuits and pending actions against the Company incidental to the operation of its business. Although the outcome of these matters, both individually and in aggregate, is currently not determinable, the Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations or liquidity. In addition to the matters referred to above, on March 14, 2025, a complaint was filed in the Supreme Court of the State of New York, County of New York by Macomb County Retiree Health Care Fund (“MCRHC”) against the Company and certain officers, directors and shareholders of the Company. The action is purportedly brought by MCRHC individually, and on behalf of others similarly situated, as a class action or in the alternative, as a derivative action on behalf of the Company. The complaint alleges, among other things, breaches of fiduciary duties for actions related to the Reclassification and seeks disgorgement, unspecified damages, costs and expenses and such other relief as the court may deem proper. At this time, the ultimate cost to resolve this matter is not reasonably estimable, however the Company believes it has substantial defenses to the alleged claims and intends to vigorously defend itself.
