Example

The example below is intended to help investors compare the cost of investing in shares of the Growth Fund with the cost of investing in other mutual funds.

The example assumes an investor invests $10,000 in shares of the Growth Fund for the time periods indicated and then redeems all shares at the end of those periods. The example also assumes that the investment has a 5% return each year and that the Fund's operating expenses remain the same. Although actual costs may be higher or lower, based on these assumptions an investor's expenses would be:

	1 year	3 years	5 years	10 years
Investor Shares	$105	$328	$569	$1,259
Institutional Shares	$81	$252	$439	$978

Portfolio Turnover

The Growth Fund may have 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 taxable distributions. Personal income taxes, which are not reflected in annual fund operating expenses or in the example, affect your after-tax returns. During the most recent fiscal year, the Fund's portfolio turnover rate was 0.00% of the average value of its portfolio.

Principal Investment Strategies

The Growth Fund invests only in common stocks, including foreign stocks. Investment decisions are made in accordance with Islamic principles. Generally, Islamic principles require that investors share in profit and loss, that they receive no usury or interest, and that they do not invest in a business that is prohibited by Islamic principles. Some of the businesses not permitted are alcohol, pornography, insurance, gambling, pork processing, and interest-based banks or finance associations.

The Growth Fund does not make any investments that pay interest. Islamic principles discourage speculation, and the Fund tends to hold investments for several years.

The Growth Fund diversifies its investments across industries and companies, and principally follows a large-cap value investment style. The Fund favors companies expected to grow earnings and stock prices faster than the economy. The Fund may also invest in smaller and less seasoned companies. The Fund seeks companies demonstrating both Islamic and sustainable characteristics. The Fund's adviser (Saturna Capital Corporation) considers issuers with sustainable characteristics to be those issuers that are more established, consistently profitable, and financially strong, and with robust policies in the areas of the environment, social responsibility, and corporate governance ("ESG"). The Fund's adviser employs a sustainable rating system based on its own, as well as third-party, data to identify issuers believed to present low risks in ESG. The Fund's adviser also uses negative screening to exclude security issuers primarily engaged in higher ESG risk businesses such as alcohol, tobacco, pornography, weapons, gambling, and fossil fuel extraction.

It is the policy of the Growth Fund, under normal circumstances, to invest at least 80% of total net assets in common stocks. The Fund's adviser (Saturna Capital Corporation) selects investments primarily on past earnings and revenue growth rates, and the expectation of increases in earnings and share price.

Principal Risks of Investing

Market risk: The value of Growth Fund shares rises and falls as the value of the stocks in which the Fund invests goes up and down. Consider investing in the Fund only if you are willing to accept the risk that you may lose money. Fund share prices, yields, and total returns will change with the fluctuations in the securities markets as well as the fortunes of the industries and companies in which the Fund invests.

Amana Growth Fund

Small-cap risk: The smaller and less seasoned companies that may be in the Growth Fund have a greater risk of price volatility. Growth stocks, which can be priced on future expectations rather than current results, may decline substantially when expectations are not met or general market conditions weaken.

Investment strategy risk: Islamic principles restrict the Growth Fund's ability to invest in certain market sectors, such as financial companies and conventional fixed-income securities. The adviser believes that Islamic and sustainable investing may mitigate security-specific risks, but the screens used in connection with these strategies reduce the investable universe, which may limit investment opportunities and adversely affect the Fund's performance. Because Islamic principles preclude the use of interest-paying instruments, cash reserves do not earn income.

Equity securities risk: Equity securities may experience significant volatility in response to economic or market conditions or adverse events that affect a particular industry, sector, or company. Larger companies may have slower rates of growth as compared to smaller, faster-growing companies. Smaller companies may have more limited financial resources, products, or services, and tend to be more sensitive to changing economic or market conditions. The Fund also tends to favor growth stocks, which tend to trade based on future earnings expectations, and may be more volatile than slower-growing value stocks, especially when market expectations are not met.

Foreign investing risk: The Growth Fund may invest in securities that are not traded in the United States when market conditions or investment opportunities arise that, in the judgment of the adviser (Saturna Capital Corporation), warrant such investment. Investments in the securities of foreign issuers may involve risks in addition to those normally associated with investments in the securities of US issuers. All foreign investments are subject to risks of: (1) foreign political and economic instability; (2) adverse movements in foreign exchange rates; (3) currency devaluation; (4) the imposition or tightening of exchange controls or other limitations on repatriation of foreign capital; (5) changes in foreign governmental attitudes towards private investment, including potential nationalization, increased taxation, or confiscation of assets; and (6) differing reporting, accounting, and auditing standards of foreign countries.

Technology sector risk: The Fund's investments technology companies exposes the Fund to risks. For example, rapid advances in science and technology might cause existing products to become obsolete, and the Fund's returns could suffer to the extent it holds an affected company's shares. A number of technology companies engaged in consumer-facing activities are potentially subject to more aggressive government regulation and intervention in their traditional business activities. This fact may affect a company's overall profitability and cause its stock price to be more volatile. Additionally, technology companies are dependent upon consumer and business acceptance as new technologies evolve.
