The following bar chart and table provide some indication of the risks of investing in the Fund by showing how the performance of the Fund’s Investor Class shares has varied over time. Of course, the Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at oberweisfunds.com or by calling 800-245-7311.

The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index and an additional index with characteristics relevant to the Fund. The table also shows returns on a before and after tax basis. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown. The after-tax return information shown does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or individual retirement account (“IRA”). After-tax returns are shown only for Investor Class and after-tax returns for Institutional Class will vary. In certain cases, the “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than or the same as other return figures for the same period. This will occur when a capital loss is realized upon the sale of Fund shares and provides an assumed tax benefit that increases the return.
