During the current year it was discoverd that the issuance of a convertible note and its subsequent conversion into common shares was not accounted for correctly in prior periods.The Foundation has restated the opening balances of net assets and accounts receivable as of January 1, 2024, to reflect the impact of recognizing the convertible promissory note and related entries in the audit. This adjustment has been applied to the Form 990 as a Prior Period Adjustment.

Financial Statement Notes

Part X : FIN48 Footnote

The foundation has received a determination letter from the IRS indicating it is a tax-exempt organization under Section 501(c)(3) of the IRC and is subject to federal income tax only on unrelated business income. Management is not aware of any transactions that would jeopardize their tax-exempt status. Accounting principles generally accepted in the USA require management to evaluate tax positions taken by the Foundation and to recognize tax liability (or asset) if the Foundation has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. Management has analyzed the tax position taken by the foundationand has concluded that as of December 31, 2024 & 2023, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Foundation is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. Management believes it is no longer subject to income tax examinations for fiscal years prior to 2020. US State jurisdictions have statutes of limitations that generally range from 3-5 years.
