<b>Example</b>

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

The example assumes an investor invests $10,000 in shares of the Developing World 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:

Expense Example - Amana Developing World Fund - USD ($)	1 year	3 years	5 years	10 years
Investor Shares	133	415	718	1,579
Institutional Shares	115	359	622	1,375

<b>Portfolio Turnover</b>

The Developing World 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 19.64% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Developing World Fund invests at least 80% of total net assets in common stocks of companies with significant exposure (50% or more of production assets, or revenues) to countries with developing economies and/or markets. 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 Developing World Fund does not make any investments that pay interest. Islamic principles discourage speculation, and the Funds tend to hold investments for several years.

The Developing World Fund diversifies its investments across the industries, companies, and countries of the developing world, and principally follows a large-cap value investment style. The Fund seeks companies demonstrating both Islamic and sustainable characteristics. The Fund's adviser 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.

In determining whether a country is part of the developing world, the Fund's adviser (Saturna Capital Corporation) will consider such factors as the country's per capita gross domestic product, the percentage of the country's economy that is industrialized, market capitalization as a percentage of gross domestic product, the overall regulatory environment, and limits on foreign ownership and restrictions on repatriation of initial capital or income.

Through reference to data provided by various globally recognized organizations such as the International Monetary Fund, The World Bank, and the Organization for Economic Cooperation and Development, the adviser maintains a list of countries it considers to have developing economies and/or markets. The list, which changes over time, currently includes: Argentina, Bahrain, Brazil, Chile, China, Colombia, Croatia, Czech Republic, Egypt, Hungary, India, Indonesia, Jordan, Kuwait, Lebanon, Malaysia, Malta, Mexico, Morocco, Oman, Panama, Peru, Philippines, Poland, Qatar, Russia, South Africa, South Korea, Taiwan, Thailand, Turkey, Ukraine, and United Arab Emirates.

By allowing investments in companies headquartered in more advanced economies yet having the majority of production assets or revenues in the developing world, the Developing World Fund seeks to reduce its foreign investing risk.

<b>Principal Risks of Investing</b>

Market risk: The value of Developing World 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 and currency markets as well as the fortunes of the industries and companies in which the Fund invests.

Investment strategy risk: Islamic principles restrict the Developing World 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.

Foreign investing risk: The Developing World Fund involves risks not typically associated with investing in US securities. 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.

Developing world risk: 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. In developing markets, these risks are magnified by less mature political systems and weaker corporate governance standards than typically found in the developed world.
