        <ExplanationTxt>In 2024, ReliabilityFirst Corporation (RF) received assessments, pursuant to section 215(c) of the Federal Power Act. The Federal Energy Regulatory Commission (FERC) has certified the North American Electric Reliability Corporation (NERC), a section 501(c)(6) nonprofit organization, as an Electric Reliability Organization (ERO) to: (1) develop and enforce reliability standards applicable to all owners, operators, and users of the bulk power system and (2) delegate any of these activities to regional entities. RF and NERC have entered into a delegation agreement that designates RF as the regional entity for its region, which consists of all or portions of 13 states and the District of Columbia. As a regional entity, RF is responsible for developing and enforcing federal electric reliability standards in the RF region pursuant to RF's delegation agreement. The purpose of RF's activities is to enhance the reliability of the bulk power system and to prevent or reduce security threats, cyber-attacks, outages, and blackouts that could otherwise cause serious risk to public health, safety, and the economy. Assessments to fund RF's budget are allocated to electric market participants (load-serving entities or designees), based upon their electric usage in the region. This funding mechanism stems from and is consistent with section 215(c)(2)(b) of the Federal Power Act, which provides that the ERO must have rules that "allocate equitably reasonable dues, fees, and other charges among end users for all activities under this section." Load-serving entities include the costs of these assessments in the total cost of electricity sold to their individual ratepayers.</ExplanationTxt>

        <ExplanationTxt>The Corporation is exempt from federal income taxes under Section 501(c)(3) of the Internal Revenue Code (the Code) and applicable state law, except for taxes pertaining to unrelated business income, if any. In accordance with the accounting standard on accounting for uncertainty in income taxes, the Corporation addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this guidance, the Corporation may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. Examples of tax positions include the tax-exempt status of the Corporation and various positions related to the potential sources of unrelated business taxable income. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. There were no unrecognized tax benefits identified or recorded as liabilities during the period covered by these financial statements. The Corporation currently files Form 990 in the U.S. federal jurisdiction. The Corporation also files the charitable registration annual report in the state of Ohio. The Corporation's federal and state returns are generally open for examination for three years following the date filed. The Corporation will account for interest and penalties related to uncertain tax positions, if any, as part of tax expense.</ExplanationTxt>

        <ExplanationTxt>ASC 842 is the new lease accounting standard that replaced ASC 840 in 2019. In recognizing leases under ASC 840, Operating leases were not reflected in the Balance Sheet. Under the new accounting standard, ASC 842, all operating leases longer than 12 months are to be on the company balance sheet. The lease must be recognized as both an asset and offsetting liability for future lease payment.</ExplanationTxt>

        <FormAndLineReferenceDesc>Part VIII, Line 1f: Explanation of Organizational Funding:</FormAndLineReferenceDesc>
        <ExplanationTxt>In 2024, ReliabilityFirst Corporation (RF) received assessments, pursuant to section 215(c) of the Federal Power Act. The Federal Energy Regulatory Commission (FERC) has certified the North American Electric Reliability Corporation (NERC), a section 501(c)(6) nonprofit organization, as an Electric Reliability Organization (ERO) to: (1) develop and enforce reliability standards applicable to all owners, operators, and users of the bulk power system and (2) delegate any of these activities to regional entities. RF and NERC have entered into a delegation agreement that designates RF as the regional entity for its region, which consists of all or portions of 13 states and the District of Columbia. As a regional entity, RF is responsible for developing and enforcing federal electric reliability standards in the RF region pursuant to RF's delegation agreement. The purpose of RF's activities is to enhance the reliability of the bulk power system and to prevent or reduce security threats, cyber-attacks, outages, and blackouts that could otherwise cause serious risk to public health, safety, and the economy. Assessments to fund RF's budget are allocated to electric market participants (load-serving entities or designees), based upon their electric usage in the region. This funding mechanism stems from and is consistent with section 215(c)(2)(b) of the Federal Power Act, which provides that the ERO must have rules that "allocate equitably reasonable dues, fees, and other charges among end users for all activities under this section." Load-serving entities include the costs of these assessments in the total cost of electricity sold to their individual ratepayers.</ExplanationTxt>
