        <ExplanationTxt>The Internal Revenue Service has advised that the Trust qualifies under Section 501(c)(5) of the Internal Revenue Code and is, therefore, exempt from income tax on activities related to its tax exempt purpose. Accounting principles generally accepted in the United States of America require management to evaluate tax positions taken by the trust and recognize a tax liability (or asset) if the organization has taken an uncertain position that more likely than not would not be sustained upon examination by the taxing authorities. As of May 31, 2025 and 2024, there were no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Trust's Forms 990, Return of Organization Exempt from Income Tax, for the fiscal years ending 2022, 2023 and 2024 are subject to examination by the IRS, generally for three years after they were filed.</ExplanationTxt>
