        <ExplanationTxt>FASB ASC 740-10 clarifies the accounting and provides guidance for uncertainty in income taxes recognized in an entity's financial statements. It prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken, in a tax return. FASB ASC 740-10-50-15 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. A plan's exempt status is a tax position that may be subject to uncertainty. There were no penalties or interest recognized in the Statement of Net Assets or in the Statement of Changes in Net Assets. Management does not believe its financial statements include any uncertain tax positions. The Fund's tax returns for the years 2022, 2023, 2024, and 2025 remain subject to examination by major tax jurisdictions.</ExplanationTxt>
