Amana Participation Fund

Investment Objective

Capital preservation and current income, consistent with Islamic principles. Capital preservation is its primary objective.

Fees and Expenses

Annual Fund Operating Expenses include all fees and expenses related to the Fund's wholly-owned and controlled subsidiary.

Example

This Example is intended to help investors compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds.

The Example assumes an investor invests $10,000 in shares of the 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	$84	$263	$458	$1,019
Institutional Shares	$60	$189	$329	$738

Portfolio Turnover

The 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 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 21.50% of the average value of its portfolio.

Principal Investment Strategies

Under normal conditions, the Fund invests at least 80% of its total net assets in short and intermediate-term Islamic income-producing investments, including for purposes of cash management. Up to 25% of the Fund's total net assets can be invested in a wholly-owned and controlled subsidiary (the "Subsidiary") that also invests in short and intermediate-term Islamic income-producing investments. The Fund (and the Subsidiary) invests primarily in notes and certificates issued for payment by foreign governments, their agencies, and financial institutions in transactions structured to be in accordance with Islamic principles. Examples of these notes and certificates include (a) sukuk, which link the returns and cash flows of financing to the assets purchased, or the returns generated from an asset purchased, (b) murabaha, which involves a purchase and sale contract, and (c) wakala, in which accounts are operated under the Islamic finance principle of wakala (an agency agreement).

These investments typically involve the purchase of financial certificates representing investments in tangible assets, project financing, sale and leaseback arrangements, and the distribution of profits (as opposed to the payment of interest) related to the underlying asset or project. Unlike an investment in a bond that represents a promise to pay interest, these investments involve the sharing of profits and losses in the assets or projects financed by the Fund's investment in the notes and certificates. In addition, the Fund may invest in time deposits with banks that involve underlying purchase and sale agreements to generate the return on the deposit.

Generally, Islamic principles require that investors participate in profit and loss, that they receive no usury or interest, and that they do not invest in a prohibited business. To the extent prohibited by Islamic investment principles the Fund does not invest in issuers whose business involves alcoholic beverages, tobacco, pornography, insurance, gambling, pork products, and interest-based banks or finance associations.

In accordance with Islamic principles, the Fund does not purchase conventional bonds, debentures, or other interest-paying obligations of indebtedness. Islamic principles discourage speculation. The Fund tends to hold investments for several years. Under normal circumstances the Fund maintains a dollar-weighted average maturity of two to five years.

The Participation Fund restricts its investments so that at least 50% are denominated in US dollars, with no more than 10% in any other single currency.

Under normal conditions, the Fund invests at least 65% of its assets in securities rated within the four highest grades (Aaa, Aa, A, Baa) by a nationally-recognized rating agency and may invest up to 35% in unrated and high-yield notes and certificates, which may be considered equivalent to "junk bonds."

The Fund is non-diversified and may invest a larger percentage of its assets in fewer issuers. In addition, the Fund may concentrate its investments within the financial services industry and real estate sector.

Amana Participation Fund

The Subsidiary's principal investment strategy and principal risks of investing are identical to those of the Fund, and the Subsidiary invests principally in sukuk, murabaha, and wakala. The Fund's investment in the Subsidiary may not exceed 25% of the value of its total net assets at the end of each quarter of its taxable year. The Subsidiary, on a consolidated basis, is also subject to the same requirements relating to liquidity, and the timing and method of valuation of portfolio investments described elsewhere in this Prospectus and in the Statement of Additional Information. The Fund is the sole shareowner of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.

Principal Risks of Investing

Market risk: The value of the Fund's shares rises and falls as the market value of the securities 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.

Diversification and concentration risks: The Fund is non-diversified and may invest a larger percentage of its assets in fewer issuers, which may cause the Fund to experience more volatility than diversified funds. In addition, the Fund may concentrate its investments within the financial services industry and real estate sector.

Investment strategy risk: The Fund's restricted ability to invest in certain market sectors, such as non-Islamic financial companies and conventional fixed-income securities, limits opportunities and may adversely affect the Fund's performance Because Islamic principles preclude the use of interest-paying instruments, cash reserves do not earn interest income but, to the extent that they are invested in murabaha or wakala, cash reserves will share in the distribution of profits (as opposed to the payment of interest) related to any murabaha or wakala investments.

Liquidity risk: Liquidity risk exists when particular investments are difficult to sell and may be more difficult to value. If the Fund is forced to sell these investments during unfavorable conditions to meet redemptions or for other cash needs, the Fund may lose money on its investments. As a result, the Fund may be unable to achieve its objective.

The Fund invests substantially in sukuk certificates that are traded outside of the US or within the US subject to certain trading restrictions which may increase the liquidity risks associated with the Fund's investments.

Foreign investing risk: The 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.

Sukuk risk: Sukuk are specifically structured to adhere to Islamic investment principles, but also must be engineered to be economically feasible in order to attract investment. Sukuk structures may be significantly more complicated than conventional bonds and often include a series of entities created specifically to support the sukuk structure. In addition, sukuk are largely created in or otherwise subject to the risks of developing economies, many of which have weak or inconsistent accounting, legal, and financial infrastructure. The structural complexity of sukuk, along with the weak infrastructure of the sukuk market, increases risks of investing in sukuk, including operational, legal, and investment risks. In addition, adherence to Islamic investment principles increases the risk of loss in the event of a default. As compared to rights of conventional bondholders, holders of sukuk may have limited ability to pursue legal recourse to enforce the terms of the sukuk or to restructure the sukuk in order to seek recovery of principal. Sukuk are also subject to the risk that issuers or Islamic scholars may deem certain sukuk as not meeting Islamic investment principles subsequent to the sukuk being issued and therefore classify the investments as noncompliant with Islamic principles.

Murabaha risk: A murabaha transaction involves a purchase and deferred-payment resale of an asset. The asset is typically purchased by an Islamic bank as agent for the Fund. The bank, acting as the Fund's agent, immediately resells the asset to a previously identified third party who agrees to repay the Fund's cost for the asset plus a profit. Murabaha investments are subject to market risk (fluctuating prices and exchange rates), credit risk, and operational risk (errors in processes).

Wakala risk: When the Fund invests in wakala, it will be subject to the credit risk of the bank acting as agent, and the risk that the bank will not manage the investment in a profitable manner.

Interest rate risk: The Fund does not invest in interest bearing investments However, since murabaha and wakala are Islamic fixed-income investments, the financial and economic data associated with interest bearing investments similarly affect the yields and returns on murabaha and wakala. Changes in interest rates impact prices of fixed-income and related investments. When interest rates rise, the value of fixed-income investments (paying a lower rate of interest) generally will fall. Investments with shorter terms may have less interest rate risk, but generally have lower returns and, because of the more frequent maturity dates, may involve higher re-investment costs.

Amana Participation Fund

Credit risk: Corporate and sovereign issuers of the notes and certificates in which the Fund invests may not be able or willing to make payments when due, which may lead to default or restructuring of the investment. In addition, if the market perceives deterioration in the creditworthiness of an issuer, the value and liquidity of the issuer's securities may decline.

High-yield risk: Securities that are rated below investment grade may have greater price fluctuations and have a higher risk of default than investment-grade securities. Below-investment grade securities may be difficult to sell at an acceptable price, especially during periods of increased market volatility or significant market decline.

Subsidiary investment risk: By investing in the Subsidiary, the Fund is subject to the risks associated with the Subsidiary's investments. Those investments are similar to the investments that are permitted to be held by the Fund and are subject to the same risks that would apply to similar investments if held directly by the Fund. The Subsidiary is organized under the laws of the Cayman Islands and is not registered with the SEC under the Investment Company Act of 1940, as amended. Accordingly, the Fund will not receive all of the protections offered to shareowners of registered investment companies. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as intended, which may negatively affect the Fund and its shareowners.

Tax risk: To qualify as a regulated investment company ("RIC"), the Fund must meet certain requirements concerning the source of its income. The Fund's investment in the Subsidiary is intended to provide exposure to murabaha and wakala in a manner that is consistent with the "qualifying income" requirement applicable to RICs. Failure to qualify as a RIC could subject the Fund to adverse tax consequences, including a federal income tax on its net income at regular corporate rates, as well as a tax to shareowners on such income when distributed as an ordinary dividend.

The tax treatment of the Fund's investment in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury Regulations, and/or guidance issued by the Internal Revenue Service that could affect the character, timing, and/ or amount of the Fund's taxable income or any gains or distributions made by the Fund.

Amana Participation Fund began operations September 28, 2015.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local taxes. After-tax returns illustrated are only for the Investor Shares; after-tax returns for Institutional Shares will vary. Actual after-tax returns depend on an investor's tax situation and likely differ from those illustrated. After-tax illustrations are not relevant to retirement plans, corporations, trusts, or other investors that are taxed at special rates. Return after taxes on distributions and sale of Fund shares may be higher than other returns for the same period due to a tax benefit of realizing a capital loss upon the sale of Fund shares.
