        <ExplanationTxt>The Trust, funding certain benefits of the Plan, received an exemption letter from the Internal Revenue Service IRS dated April 11, 2018, stating that the Trust is tax exempt under the provisions of Section 501c9 of the IRC. However, as a result of the Plans funding policy, from time to time, the Trust may be subject to income taxes. The Plan paid 135,410 and 249,525 in unrelated business income taxes during the years ended December 31, 2021 and 2020, respectively. These amounts included state income taxes for unrelated business taxable income, when applicable. In addition, the Plan and the Trust are required to operate in conformity with the IRC to maintain the tax-exempt status of the Trust. The Plan Administrator believes that the Plan is being operated in compliance with the applicable requirements of the IRC, and therefore, believes that the related Trust is tax exempt. U.S. GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability or asset if it has taken an uncertain tax position that more-likely-than not would not be sustained upon examination by the IRS and state jurisdictions. The Plan is subject to routine audits by taxing jurisdictions however, there are currently no audits for any tax periods in progress.</ExplanationTxt>
