Legal Proceedings	NOTE 11 — LEGAL PROCEEDINGS: On April 19, 2022, the US District Court for the District of Delaware granted judgment in favor of the Company in its trademark infringement lawsuit against air conditioning and heating products provider Emerson Quiet Kool and wholesaler Home Easy (the “defendants”). Among other things, the court order issues an injunction and directs the US Patent and Trademark Office to cancel the defendants’ existing and proposed “Emerson Quiet Kool” trademarks and prohibits defendants from registering or applying to register the same mark or any other mark or name containing the word “Emerson” going forward. The judgment also awards $6.5 million to the Company. Like any judgment, there is no guarantee that the Company will be able to collect the judgment or, if it is able to collect, how soon it will be able to do so. The Company is pursuing various post-judgment motions against defendants. The defendants have filed a notice of appeal of the judgment. The Company is not currently a party to any other legal proceedings other than litigation matters, in most cases involving ordinary and routine claims incidental to its business. Management cannot estimate with certainty the Company’s ultimate legal and financial liability with respect to such pending litigation matters. However, management believes, based on its examination of such matters, that the Company’s ultimate liability will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.
