        <ExplanationTxt>Accounting principles generally accepted in the United States of America requires management to evaluate tax positions taken and recognize a tax liability if the entity has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. Management has evaluated the tax positions taken by the Plan and concluded that as of December 31, 2023 and 2022 there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits in progress for any tax periods. In addition, there have been no tax related interest or penalties for the period presented in these financial statements.</ExplanationTxt>
