        <ExplanationTxt>ASC topic #740, "Income Taxes" requires that an enterprise cannot recognize a tax benefit in its financial statements unless it concludes that it is "more likely than not: that the benefit will be sustained on audit by the taxing authority". Tax-exempt and not-for-profit enterprises are also within the scope of the ASC, since the decision that some or all of an enterprise's activities are not subject to income taxes is itself a tax position for which the interpretation requires evaluation. At adoption, and annually thereafter, San Miguel applies the requirements to all tax positions for which the statute of limitations remained open. San Miguel recognizes the financial benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. San Miguel Electric Cooperative, Inc. was determined by the Internal Revenue Service to be an exempt cooperative for purposes of federal income taxes, under Section 501 (c)(12) of the Internal Revenue code, in years when receipts from members, for the prose of meeting losses and expenses, are at least 85 percent of the total income. The amount of unrecognized tax benefits as of December 31, 2024, was zero.</ExplanationTxt>

        <ExplanationTxt>For the 2011 tax reporting year, the IRS made a significant change to the 990 instructions, whereby entites exempt under 501 (c)12) of the Internal Revenue Code are to report patronage dividend paid to their members on Part IX, Line 4. San Miguel being duly organized in the State of Texas and exempt under 501 (c)(12) of the Internal Revenue code operates on a cooperative, non-profit basis for the mutual benefit of its patrons. As such, all revenues or margins received in excess of operating costs are retained as equity and allocated a credit to each patron's capital account. Should the Board of directors determine that the financial conditions of the cooperative will not be impaired, and there are not requirements which restrict such distribution, the Board of Directors may choose to retire credits reflected in member accounts in part or in full. Retirements of capital credits are restricted under San Miguel's current mortgage indenture until certain thresholds be met. San Miguel interprets the definition of "paid" to mean paid in money, property, or qualified written allocations: therefore, San Miguel is reporting as allocate, for the 2011 and all subsequent tax reporting years, all excess margins as paid to its patrons on an annual basis in accordance with the above referenced interpretations fo the IRS instructions.</ExplanationTxt>
