Factors Affecting Performance [Text Block]
Management's Discussion of Fund Performance

Management attributes the Fund's performance, in comparison to that of its benchmark, to a variety of factors. The Fund's portfolio is actively managed, meaning that stocks are added and/or removed based on management's decision if the stock fits management's value criteria. The difference between the Fund and the benchmark, the S&P 500 Index (the "Index"), is the Index is a passively managed basket of 500 different stocks. Many feel that the Index is a good indicator of the performance of the entire stock market in general. As a part of the Fund's risk mitigation strategy, investors should be aware that during market upswings, the Fund may underperform the benchmark. However, during market downturns the Fund typically outperforms the benchmark. For the period covered in this report, the Fund outperformed the S&P 500 due to the combination of holding quality stocks and being patient during market downswings. The Fund will continue to hold high quality value stocks and the continued use of buying dividend-paying companies with good balance sheets and strong cash flows even when value stocks are out of favor.
