​ Accounts payable: ​ During the second quarter of 2024, management requested outside legal counsel to provide guidance with respect to various accounts payables carried on the books from 2020 and prior. Based on the review of the statute of limitations for the various states these vendors were located, legal counsel provided a conclusion regarding whether the laws per the respective states provided that the statute of limitations has expired. The statute of limitations is an affirmative defense in which the defendant introduces evidence, which, if found to be credible, will negate criminal or civil liability, even if it is proven the defendant committed the alleged acts. The party raising the affirmative defense has the burden of proof on establishing that it applies. In a civil action in which a creditor demands payment on a written instrument evidencing a debt, the successful assertion of the statute of limitations defense will bar collection of the debt. In order to assert the statute of limitations as a defense, a defendant must specifically assert the defense is the answer. If a defendant fails to specifically plead the defense, it will be deemed to be waived. Since no action to enforce such liabilities was brought before September 30, 2024, it is our opinion that the liability is time-barred from collection under the respective state laws and should be removed from the Company’s balance sheet. ​ Therefore, the Company made the decision to write-off the payables totaling $429 thousand. As of September 30, 2024, the write-off of $429 thousand resulted in a gain on extinguishment of debt which was reported on the statement of operations for the nine months ended September 30, 2024. |
