Fee Table
This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. 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 breakpoints can be found under “Distribution Arrangements” on page 13 of this prospectus.

	Class E
SHAREHOLDER FEES: (fees paid directly from your investment)
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	5.75%
Maximum deferred sales charge (load) as a percentage of original purchase price or redemption proceeds, whichever is lower	1%
Maximum sales charge (load) imposed on reinvested dividends	None
Redemption Fees	None
Exchange Fee	None
Maximum Account Fee	None

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment) ended July 31, 2015:

Management Fees	1.00%
Distribution and Service (12b-1) fees	0.30%
Other Expenses	5.57%
Total Annual Fund Operating Expenses	6.87%

This 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:

	1 Year	3 Years	5 Years	10 Years
Class E	$1,216	$2,464	$3,664	$6,476

You would pay the following expenses if you did not redeem your shares:

Class E $1,216 $2,464 $3,664 $6,476

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 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’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Principal Investment Strategy
Investment Research Corporation (the "Adviser") manages the Fund by searching for companies/investments with growth potential that could show faster growth than markets indexes. The Adviser also looks for securities that are considered undervalued or out of favor with investors or are expected to increase in price over time. We use a consistent approach to build the Fund’s security portfolio which is made up primarily of common stocks involved, in at least some way, in the legal cannabis business. In addition to the principal investment strategy, we may also invest in securities

Series Two Prospectus Page 3

convertible into common stock in companies involved, in at least some way, in the legal cannabis business. Examples of companies associated with the legal cannabis industry could include legally registered publicly traded companies in fields such as agriculture, pharmaceutical, hydroponic or tobacco companies or REITs. These securities may be issued by large companies and also small and mid-sized companies, Micro Cap and REITs. Income through dividend payments is a secondary objective. Income also becomes a Fund objective when it is in a temporary, defensive position. The legal cannabis business does not need to be the sole focus point of a company for Series Two to invest in it nor does it need to account for a majority of its overall revenues. For example, Series Two may invest in Company XYZ, a pharmaceutical company developing uses for medical cannabis even if the revenues produced as a result of the sales of medical cannabis is responsible for less than 5% of XYZ’s overall revenue.

Principal risks of investing in the Fund
The primary risks of investing in the Fund are:

General Risk - All investments are subject to inherent risk. Markets can trade in random or cyclical price patterns and prices can fall over time. The value of Series Two can fluctuate as markets fluctuate over long and short periods of time.

Political, Economic and Regulatory Risk - Changes in economic and tax policies, high inflation rates, government instability, and other political or economic actions or factors that may have an adverse effect on Series Two. Governmental and regulatory actions, including law changes, may have unexpected or adverse consequences on particular markets, strategies, or investments. Legislation or regulation may also change the way in which Series Two itself is regulated. Series Two cannot predict the effects of any new governmental regulation or law that may be implemented on the ability of Series Two to invest in certain assets, or the possible effect on our ability to access financial markets, and there can be no assurance that any new governmental regulation will not adversely affect Series Two’s ability to achieve its investment objectives,

Cannabis Industry Risk – The cannabis industry is a very young, fast evolving industry with possible increased exposure to rule changes, changes in laws, increasing regulations, increasing competition which may cause businesses to suddenly close or businesses to shrink as well as the possibility that a company currently operating legally may suddenly find itself exposed to illegal activities.

REITs Risk - Under its modified fundamental investment policies, Series Two may invest in REITs (Real Estate Investment Trust), including Equity REITs and Mortgage REITs. Equity REITs invest directly in property while Mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real property including declines in the value of real estate, risks related to general and local economic conditions, over building and increased competition, increase in property taxes and operating expenses, and variations in rental income. REITS are dependent on management skills, are not diversified, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation. REITs (especially mortgage REITs) are also subject to interest rate risk. When interest rates decline, the value of a REIT’s investment in fixed-rate obligations can be expected to rise. Conversely, when interest rate rise, the value of a REIT’s investment in fixed-rate obligations can be expected to decline. Mortgage REITs may be affected by the quality of any credit extended to them,

Stock Market Risk - the value of an investment may fluctuate,

Industry and Security Risk - risks relating to an industry as a whole or a company’s prospects for business success,

Management Risk - risks that the Adviser’s assessment of a company’s growth prospects may not be accurate,

Liquidity Risk - Series Two may face increased liquidity risk which is the risk that a given security or asset may not be readily marketable,

Series Two Prospectus Page 4

Small Cap Risk - small cap stocks tend to have a high exposure to market fluctuations and failure,

Mid Cap Risk - mid cap stocks tend to have a greater exposure to market fluctuations and failure,

Micro Cap Risk - low-priced stocks issued by the smallest of companies. Many microcap companies do not file financial reports with the SEC, so it's hard for investors to get the facts about the company's management, products, services, and finances. Microcap stocks historically have been more volatile and less liquid than the stock of larger companies,

Convertible Security Risk - risk of loss of principal before maturity,

New Issuer Risk - New Issuers have been in the business less than 3 years, may face increased pressures from established companies, new unseasoned management, may be more volatile and may offer less liquidity then larger companies.

Loss of some or all of the money you invest is a risk of investing in Series Two.
Because of the nature of the Fund, you should consider the investment to be a long-term investment that typically provides the best results when held for a number of years.
Please see the Statement of Additional Information for further discussion of risks.

Tax Consequences

Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s Web site for more information.

Investment Objectives, Principal Investment Strategies, Related Risks, and Disclosure of Portfolio Holdings
What is the Fund’s investment objective?
The Fund’s investment objective, which is fundamental and cannot be changed without shareholder approval, is growth of capital. Income through dividend payments is a secondary objective. Income also becomes a Fund objective when it is in a temporary, defensive position.

How does the Fund implement its principal investment objective?
In attempting to achieve its principal investment objective, the Fund will attempt to invest at least 80% of its assets in securities involved at least some way in the legal cannabis business. Securities convertible into common stocks traded on national securities exchanges or over-the-counter or REITs may also be utilized. Examples of companies associated with the legal cannabis industry could include legally registered publicly traded companies in fields such as agriculture, pharmaceutical, hydroponic or tobacco companies or REITs. The legal cannabis business does not need to be the sole focus point of a company for Series Two to invest in it nor does it need to account for a majority of its overall revenues. For example, Series Two may invest in Company XYZ, a pharmaceutical company developing uses for medical cannabis, even if the revenues produced as a result of the sales of medical cannabis is responsible for less than 5% of XYZ’s overall revenue.

Series Two Prospectus Page 6

At the time of purchase, with respect to 75% of the Fund's total assets, we do not invest more than 5% in any one issuer nor do we invest more than 25% in any one industry. We also follow a rigorous selection process designed to identify undervalued securities before choosing securities for the portfolio.

The Fund may invest in companies of all sizes. Investment Research Corporation, the Fund’s investment adviser (the Adviser or IRC), will choose securities that it believes have a potential for capital appreciation because of existing or anticipated economic conditions or because the securities are considered undervalued or out of favor with investors or are expected to increase in price over time.

The Fund may invest in Real Estate Investment Trusts (“REITs”) if the investment committee believes that it could be advantageous to the stockholders. These REITs could be involved in the areas of the legal cannabis business such as property development and rental or other legal endeavors associated with the legal cannabis business.

Using the following approach, we look for companies having some of these characteristics:

~ Companies and/or securities involved legally in the cannabis business;
~ Large capitalization companies, although the Fund may invest in companies of all sizes, if the Adviser believes it is in the best interests of the Fund. Large cap companies are generally companies with market capitalization exceeding $5 billion at the date of acquisition;
~ growth that is faster than the market as a whole and sustainable over the long term;
~ strong management team;
~ leading market positions and growing brand identities;
~ financial, marketing, and operating strength.

When the Adviser believes the securities the Fund holds may decline in value, the Fund may sell them and, if the Adviser believes market conditions warrant the Fund may assume a temporary defensive position. While in a defensive position, the Fund may invest all or part of its assets in corporate bonds, debentures (both short and long term) or preferred stocks rated A or above by Moody Investors Service, Inc., Standard and Poor’s, or Fitch Ratings (or, if unrated, of comparable quality in the opinion of the Adviser), United States Government securities, repurchase agreements meeting approved credit worthiness standards (e.g., whereby the underlying security is issued by the United States Government or any agency thereof), or retain funds in cash or cash equivalents. There is no maximum limit on the amount of fixed income securities in which the Fund may invest for temporary defensive purposes. If the Fund takes a temporary defensive position in attempting to respond to adverse market, economic, political or other conditions, it may not achieve its investment objective. The Fund’s performance could be lower during periods when it retains or invests its assets in these more defensive holdings.
