Amana Developing World ETF

The  30-day median bid-ask spread is the highest price a buyer is willing to pay for shares, and the ask is the lowest price a seller is willing to accept. The difference between those two prices is the bid-ask spread. Wider spreads generally indicate higher transaction costs. Spreads may change based on market conditions, trading volume, and the liquidity of the ETF’s underlying holdings.

Each Fund operates as an exchange-traded fund (“ETF”) and offers and issues Shares at net asset value (“NAV”) only in aggregations of a specified number of Shares (each, a “Creation Unit). Similarly, Shares are redeemable by a Fund only in Creation Units. Only Authorized Participants (as defined in the “Creation and Redemption of Creation Units” section of this SAI) who have entered into contractual arrangements with the Funds’ Distributor may enter into Creation Unit transactions with a Fund on behalf of themselves or their customers. Creation Units of the Funds are issued and redeemed generally in exchange for a basket of securities (“Basket”), that may include a specified cash payment, or, in certain circumstances, for an all cash payment. Unlike shares of mutual funds, Fund Shares are not individually redeemable securities.

The Fund issues and redeems shares only in large blocks called “Creation Units” at NAV next determined after an order is accepted. Only authorized participants (“APs”) may transact in Creation Units directly with the Fund. Investors should contact their broker or financial intermediary to place trades.

If the exchange-traded fund's premium or discount is greater than 2% for more than seven consecutive trading days, a statement that the exchange-traded fund's premium or discount, as applicable, was greater than 2% and a discussion of the factors that are reasonably believed to have materially contributed to the premium or discount, which must be maintained on the website for at least one year thereafter.

As with all funds, investing in the Fund entails risks that could cause the Fund and the Fund’s investors to lose money. The principal risks of investing in the Fund are as follows: 

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. 

Investment strategy risk: Islamic principles restrict the Fund’s ability to invest in certain market sectors, such as financial companies and conventional fixedincome 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 positions 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. 

Developing world and foreign investing risk: 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.

ETF Risk: As an exchange-traded fund (“ETF”), the Fund is subject to the following risks:

Authorized Participants Concentration Risk: The Fund has a limited number of financial institutions that may act as authorized participants (“APs”). Only APs may transact in creation and redemption transactions directly with the Fund, and APs are not obligated to engage in such transactions. To the extent they exit the business or are otherwise unable or unwilling to proceed in creation and redemption transactions with the Fund, such as in times of market stress, and no other authorized participant is able to step forward to create or redeem, trading in Fund shares may be significantly diminished, bid-ask spreads may widen and shares of the Fund may be more likely to trade at a premium or discount to net asset value (“NAV”) and possibly face trading halts or delisting. To the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes, this risk is heightened. 

International Closed Market Trading Risk: Because certain of the Fund’s investments trade in markets that are closed when the Fund and the Nasdaq Global Market (“Exchange”) are open, there are likely to be deviations between the current prices of such investments and the prices at which such investments are marked for purposes of the Fund’s NAV ( i.e., the Fund’s quote from the closed foreign market). As a result, premiums or discounts to NAV may develop in share prices, and bid-ask spreads may be greater than those experienced by other funds. In addition, shareowners may not be able to purchase or redeem their shares of the Fund, or purchase or sell shares of the Fund on the Exchange, on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

Premium-Discount Risk: There may be times when the market price of the Fund’s shares is more than the NAV intra-day (at a premium) or less than the NAV intra-day (at a discount). As a result, shareowners of the Fund may pay more than NAV when purchasing shares and receive less than NAV when selling Fund shares. This risk is heightened in times of market volatility or periods of steep market declines. In such market conditions, market or stop loss orders to sell Fund shares may be executed at prices well below NAV.

Secondary Market Trading Risk: Investors buying or selling shares in the secondary market will normally pay brokerage commissions, which are often a fixed amount and may be a significant proportional cost for investors buying or selling relatively small amounts of shares. Secondary market trading is subject to bid-ask spreads, which is the difference between the highest price a buyer is willing to pay to purchase shares of a fund (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling shares in the secondary market, and trading in Fund shares may be halted by the Exchange because of market conditions or other reasons. If a trading halt occurs, a shareowner may temporarily be unable to purchase or sell shares of the Fund. The bid-ask spread, which varies over time, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, the bid-ask spread can be affected by the liquidity of the Fund’s underlying investments and can widen if the Fund’s underlying investments become less liquid or illiquid. In addition, although the Fund’s shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained, that bid-ask spreads will be narrow, or that the Fund’s shares will continue to be listed.

Cash Transactions Risk: The Fund may effect redemptions partly or wholly for cash, rather than through in-kind distributions of securities. Accordingly, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds and it may recognize gains on sales of portfolio holdings. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that primarily or wholly effects redemptions in-kind. Moreover, cash transactions may have to be carried out over several days if the securities markets are relatively illiquid at the time the Fund must sell securities and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund redeemed its shares principally in-kind, may be passed on to APs in the form of transaction fees. As a result, the spreads between the bid and the offered prices of the Fund’s shares may be wider than those of shares of ETFs that primarily or wholly transact in-kind.

Large Shareowner Risk: Certain shareowners may own a substantial amount of the Fund’s shares. Redemptions by large shareowners could have a significant negative impact on the Fund and transactions on the Exchange by large shareowners may have a material upward or downward effect on the market price of the shares.

New Fund Risk: The Fund is new and does not have shares outstanding as of the date of this Prospectus. The Fund may not be successful in implementing its investment strategy, and its investment strategy may not be successful under all future market conditions, either of which could result in the Fund being liquidated at some future time without shareowner approval and/or at a time that may not be favorable for certain shareowners. New funds may not attract sufficient assets to achieve investment, trading or other efficiencies and, if the Fund does not grow in size, it will be at greater risk than larger funds of wider bid-ask spreads for its shares, trading at a greater premium or discount to NAV and/or a stop to trading.
