“Aps is exempt from federal income tax under section 501(c)(3) of the internal revenue code and has been classified as an organization that is not a private foundation. Aps had an immaterial amount of unrelated business income for the years ended december 31, 2023 and 2022. Under accounting standards codification (asc) 740-10, accounting for uncertainty in income taxes, an organization must recognize the tax benefit associated with tax positions taken for tax return purposes when it is more-likely than not that the position will be sustained. Aps does not believe there are any material uncertain tax positions and; accordingly, will not recognize any liability for unrecognized tax benefits. Aps has filed for and received income tax exemptions in the jurisdictions where it is required to do so. Additionally, aps has filed internal revenue service form 990 tax returns as required and all applicable returns in those jurisdictions where it is required. Aps believes that it is no longer subject to u.s. Federal, state and local, or non-u.s. Income tax examinations by tax authorities for years ended december 31, 2019 and prior. However, aps is still open to examinations by tax authorities from fiscal year 2020 forward. For the years ended december 31, 2023 and 2022, there were no interest or penalties recorded in the accompanying statements of activities.”
