        <ExplanationTxt>The Association is organized as a Kansas nonprofit corporation and has been recognized by the IRS as exempt from federal income taxes under IRC Section 501(a) as an organization described in IRC Section 501(c)(3). Further, the Association qualifies for the charitable contribution deduction under IRC Sections 170(b)(1)(A)(vi) and has been determined not to be a private foundation under IRC Sections 509(a)(1). The Association is annually required to file a Return of Organization Exempt from Income Tax (Form 990) with the IRS. In addition, the Association is subject to income tax on net income that is derived from business activities that are unrelated to its exempt purposes. For the year ended December 31, 2024, the Association has determined that it is not subject to unrelated business income tax and has not filed an Exempt Organization Business Income Tax Return (Form 990-T) with the IRS. Returns are subject to IRS examination, generally for three years after each return is filed. No taxing authorities have commenced income tax examinations for open tax years.</ExplanationTxt>
