| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? The performance of the Fund is mainly driven by the level of short-term interest rates. During the Fund’s fiscal year, the Federal Reserve maintained interest rates at or above 5%. This increased the Fund’s net investment income by approximately $300,000. Since the Fund distributes 100% of its net investment income, dividends to shareholders were higher. The Fund also distributed $301,279 in capital gains. Fund performance is also affected by its size. During the fiscal year average assets decreased approximately $51 million. This caused the Fund’s expense ratio to exceed 1.00%. This increase was offset by the waiver of $87,123 in expenses by the adviser. During the fiscal year ended June 30, 2024, the Fund’s current investment strategies did not cause performance to materially deviate from expectations. |
