        <ExplanationTxt>The Foundation is organized as a not-for-profit organization and is exempt from income taxes under section 501(c)(3) of the Internal Revenue Code. Unrelated business income, of which the Foundation had none for the years ended December 31, 2022, 2021, and 2020, would be subject to federal income taxes. The Foundation's information returns filed with the Internal Revenue Service have not been examined in the past. The Foundation is not aware of any uncertainties that could jeopardize its not-for-profit status. Therefore, no provision or liability for income taxes is deemed necessary. The Foundation follows the provisions of uncertain tax positions addressed by FAS ASC 740-10 Accounting for Uncertainty in Income Taxes. The Foundation has no uncertain tax positions at December 31, 2021, for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. The Foundation recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expense. The Foundation has determined that no amount is required to be accrued for taxes or related penalties and interest for any tax position taken through December 31, 2021.</ExplanationTxt>
