Expenses Example

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

The example assumes an investor invests $10,000 in the Developing World Fund for the time periods indicated and then redeems 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 cumulative expenses would be:

1 year	3 years
$144	$447

Portfolio Turnover Rate

The Developing World Fund began operations on September 28, 2009 (the date of this Prospectus) and consequently has not yet made any purchases or sold any securities, and therefore does not have a portfolio turnover rate to report.The Fund buys and sells securities through Saturna Brokerage Services, Inc. (SBS), a wholly-owned subsidiary of Saturna Capital, which charges no commissions on portfolio trades.

Principal Investment Strategies

The Developing World Fund only buys stocks of companies with significant exposure (50% or more of assets or revenues) to countries with developing economies and/or markets. Investment decisions are made in accordance with Islamic principles. The Fund diversifies its investments across the countries of the developing world, industries, and companies, and generally follows a value investment style.

In determining whether a country is part of the developing world, the adviser 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.

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

Principal Risks of Investing

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. Only consider investing in the Fund 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.

The Developing World Fund involves risks not typically associated with investing in U.S. securities. These include fluctuations in currency exchange rates, currency devaluation, less public information about securities, less governmental market supervision, and lack of uniform financial, accounting, social and political standards.

Foreign countries have risk of confiscatory taxation, seizure or nationalization of assets, establishment of exchange controls, adoption of government restrictions, or adverse political or social developments that affect investments. The risks of foreign investing are generally magnified in the smaller and more volatile securities markets of the developing world. The Developing World Fund’s restricted ability to invest in certain market sectors, such as financial companies and fixed-income securities, limits opportunities and may increase the risk of loss during economic downturns. Because Islamic principles

preclude the use of interest-paying instruments, the Developing World Fund does not maximize current income because reserves remain in cash.

Performance

The Developing World Fund began operations on September 28, 2009 and consequently has no historical returns to report. Future reports will show how the Fund’s average annual total returns for the required time periods compare with the Morgan Stanley Capital International (MSCI) Emerging Markets index.

A fund’s past performance (before and after taxes) is not a guarantee of how a fund will perform in the future.

Performance data current to the most recent month-end and quarter-end are available on www.amanafunds.com.

Payments to Broker-Dealers and Other Finanical Intermediaries

If you purchase the Developing World Fund through a broker-dealer or other financial intermediary (such as a bank or investment adviser), the Fund and its related companies may pay the intermediary for the sale of shares and related services. These payments may create a conflict of interest by influencing the intermediary and your sales person to recommend the Fund over another investment. Ask your salesperson or visit your broker-dealer or other financial intermediary’s website for more information.
