You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the American Growth Fund. More information about these and other discounts is available from your financial professional and in How to Reduce your Sales Charge, page 11 of the Fund&#180;s prospectus and under Distribution of Fund Shares, Page 15 of the Fund&#180;s statement of additional information. <b>SHAREHOLDER FEES: (fees paid directly from your investment)</b> <b>Annual Fund Operating Expenses</b> (Expenses that you pay each year as a percentage of the value of your investment) ended July 31, 2014: 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&#180;s operating expenses remain the same. Seven years after the date of purchase, Class C Shares automatically convert to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: You would pay the following expenses if you did not redeem your shares: <b>Portfolio Turnover</b> The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate 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&#180;s performance. During the most recent fiscal year, the Fund&#180;s portfolio turnover rate was 3% of the average value of its portfolio. <b>Principal Investment Strategy</b> Investment Research Corporation (the "Adviser") manages the Fund using a growth style of investing. We use a consistent approach to build the Fund&#180;s security portfolio which is made up primarily of common stocks and securities convertible into common stock. These securities are issued by large companies, and to a lesser extent, small and mid-sized companies. When a company&#180;s fundamentals are strong, we believe earnings growth will follow. <b>Principal risks of investing in the Fund</b> The primary risks of investing in the Fund are:<ul type="square"><li>Stock Market Risk - the value of an investment may fluctuate,</li><li>Industry and Security Risk - risks relating to an industry as a whole or a company&#180;s prospects for business success,</li><li>Management Risk - risks that the Adviser&#180;s assessment of a company&#180;s growth prospects may not be accurate,</li><li>Liquidity Risk - a given security or asset may not be readily marketable,</li><li>Small Cap Risk - small cap stocks tend to have a high exposure to market fluctuations and failure,</li><li>Mid Cap Risk - mid cap stocks tend to have a greater exposure to market fluctuations and failure.</li></ul>Loss of some or all of the money you invest is a risk of investing in the Fund. <b>Risk/Return Bar Chart and Table</b> The bar chart and table are intended to provide you with an indication of the risks of investing in the Fund by showing changes in performance from year to year and by showing how the Fund&#180;s average annual returns for 1, 5 and 10 years compare to those of the Standard and Poors 500 total return.
