Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected its performance? For the twelve months ended August 31, 2024, the Fund returned 5.01%. The Fund underperformed the S&P 500 Index, which returned 22.15%, and the blended 60% Russell 2000/40% Bloomberg US Government/Credit Bond Index, which returned 11.78%. The Fund seeks to find value through out of favor, overlooked, or misunderstood securities. What Factors Influenced Performance During the period, inflation concerns eased and the stock market began anticipating Fed interest rate cuts. In addition, artificial intelligence led to a surge in large cap tech stocks (such as Google’s parent Alphabet, Amazon, Apple, Meta Platforms, Microsoft and Nvidia). This surge drove the performance of the S&P 500 Index. The Advisor, as an opportunistic capital allocator with a deep-value bias in selecting individual securities, did not select securities that participated in this run. The Fund also held an average of nearly 25% cash and cash equivalents, which caused a drag on performance. Top Contributors to Performance: Dundee Precious Metals Inc. increased approximately 50% in value and represented 9.1% of the Fund’s portfolio as of August 31, 2024. Liberty Energy Inc. increased approximately 29% in value and represented 8.7% of the Fund’s portfolio as of August 31, 2024. Top Detractors from Performance: The Fund’s position in Quantum Corp. was fully liquidated, which resulted in a loss of approximately 55% from the beginning of this fiscal year. The Fund’s position in Collplant Biotechnologies Ltd. was fully liquidated, which resulted in a loss of approximately 25% from the beginning of this fiscal year.
