This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.


Shareholder Fees

Redemption Fee on shares redeemed within 90 calendar days of purchase (as a percentage of amount redeemed)


Exchange Fee on shares exchanged within 90 calendar days of purchase (as a percentage of amount exchanged)

Total Annual Fund Operating Expenses








The example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


One Year: $203

  Three Years: $627   Five Years: $1,078   Ten Years: $2,327


Portfolio Turnover


The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its

portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 48% of the average value of its portfolio.


Principal Investment Strategies


The Fund invests, under normal circumstances, at least 80% of its net assets in the securities of very small companies which, at the time of purchase, have a market capitalization of less than or equal to $600 million or are within the range of companies represented in the Russell Micro-Cap Growth Index, whichever is greater and meet the Oberweis Octagon investment criteria described below. The Fund invests principally in the common stocks of companies that the Fund’s investment adviser, Oberweis Asset Management, Inc. (“OAM”), believes have the potential for significant long-term growth in market value.


The Fund seeks to invest in those companies which OAM considers to have above-average long-term growth potential based on its analysis of eight factors, which OAM calls the “Oberweis Octagon.” These factors are:


1. At least 30% growth in revenues in the latest quarter. OAM prefers this to be generated from internal growth as opposed to acquisition of other businesses.


2. At least 30% growth in pre-tax income in the latest quarter. There should also be rapid growth in earnings per share.


3. There should be a reasonable price/earnings ratio in relation to the company’s underlying growth rate. In order to be considered for investment, companies must generally have a price/earnings ratio not more than one-half of the company’s growth rate.


4. Products or services that offer the opportunity for substantial future growth. Such growth generally




either stems from products in newer, high growth markets or products with the potential to grow market share within an existing market. In the latter case, such products typically grow market share due to competitive advantages over other market offerings. Examples of such advantages include new technologies, patents and niche market positions with high barriers to competitive entry.


5. Favorable recent trends in revenue and earnings growth, ideally showing acceleration.


6. Reasonable price-to-sales ratio based on the company’s underlying growth prospects and profit margins.


7. A review of the company’s financial statements, with particular attention to footnotes, in order to identify unusual items which may indicate future problems.


8. High relative strength in the market, in that the company’s stock has outperformed at least 75% of other stocks in the market over the preceding twelve months.


OAM considers these eight factors as guidelines for evaluating the many companies it reviews to identify those companies that have the potential for above-average long-term growth. Such factors and the relative weight given to each will vary with economic and market conditions and the type of company being evaluated. No one factor will justify, and any one factor could rule out, an investment in a particular company.


Principal Risks


The biggest risk is that the Fund’s returns may vary, and you could lose money by investing in the Fund. Because the Fund may invest substantially all of its assets in common stocks, the main risk is that the value of the stocks it holds might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, the Fund’s share price may also decrease.


The Fund is designed for long-term investors who seek growth of capital and who can tolerate the greater risks associated with seeking maximum capital appreciation. Investment in common stocks, particularly in common

stocks of small companies with high growth potential, can be volatile. The value of the Fund’s shares will go up and down due to movement of the overall stock market or of the value of the individual securities held by the Fund. Because of this volatility, we recommend that you invest in the Fund as a long-term investment only, and only for a portion of your investment portfolio, not for all of it. There can be no assurance that the Fund’s objective will be met.


Small-sized Company Risk—The Fund is subject to small company risk. Although the Fund seeks to reduce risk by investing in a diversified portfolio, you must realize that investing in smaller, and often newer, companies involves greater risk than there usually is with investing in larger, more established companies. Smaller and newer companies often have limited product lines, markets, management personnel, research and/or financial resources. The securities of small companies, which may be thinly capitalized, may not be as marketable as those of larger companies. Therefore the securities of these smaller, newer companies may be subject to more abrupt or erratic market movements than the securities of larger companies or the market averages in general.


Micro-Cap Risk—Small-sized company risk is intensified for the Fund. The prices of micro-cap companies are generally more volatile and their markets are less liquid relative to larger companies. An investment in the Fund may involve considerably more risk of loss and its returns may differ significantly from funds investing in larger companies.


Investment Style Risk—There is no assurance that the common stocks of companies selected using the “Oberweis Octagon” investment criteria will achieve long-term growth in market value.
