| Explanation | Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan and recognize a tax liability or asset if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. There are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements as of December 31, 2024 and 2023.The Plan is subject to routine audits by taxing jurisdictions however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2021. | ExplanationTxt |
