Distributions

The Amana Developing World Fund intends to distribute its net investment income and net realized capital gains, if any, to its shareowners. Distributions from net capital gains are paid at the end of December and May; income dividends are paid at the end of December — as a result of its investment strategy, the Developing World Fund may not pay income dividends.

Dividends paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time.

Both dividends and capital gain distributions are paid in additional full and fractional shares of the share class owned. At your option, you may receive dividends and/or capital gain distributions in cash. You are notified of each dividend and capital gain distribution when paid. Returned dividend payments will be automatically reinvested into your account and invested in additional shares of the Fund; future dividends in such accounts will continue to be reinvested until the shareowner is located or the account is closed.

The Amana Developing World Fund Investor Shares (AMDWX) began operations September 28, 2009 and Institutional Shares began operations September 25, 2013. The Fund's entire distribution history is listed above.

Regulations regarding distributions can be complex, and there are several methods for managing your tax liability. Please consult a tax advisor about your particular circumstances. You also may obtain helpful information by calling the Internal Revenue Service at 1-800-829-1040 or visiting www.irs.gov.

If applicable, distribution information will appear on Form 1099-DIV, typically sent in late January. For more information on tax documentation, please visit our Tax Documentation page.

The Fund pays per-share distributions to shareowners invested on the Record Date. On the Payable Date, the fund's share price is reduced by the amount of its distribution.

Principal Risks of Investing in the Fund

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 toward 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.
