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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;The Income Fund does not make any investments that pay interest. Islamic principles discourage speculation, and the Fund tends to hold investments for several years.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;The Income Fund diversifies its investments across industries and companies, and principally follows a large-cap value investment style. Common stock purchases are restricted to dividend-paying companies. The Fund seeks companies demonstrating both Islamic and sustainable characteristics. The Fund's adviser (Saturna Capital Corporation) 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;It is the policy of the Income Fund, under normal circumstances, to invest at least 80% of its total net assets in income-producing securities, primarily dividend-paying common stocks.&lt;/div&gt;</rr:StrategyNarrativeTextBlock>

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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Investment strategy risk:&lt;/div&gt; Islamic principles restrict the Income Fund's ability to invest in certain market sectors, such as financial companies and conventional fixed-income&lt;/div&gt;
&lt;div style="margin-top: 0pt; margin-bottom: 12pt; line-height: 12pt;"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Equity securities risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Foreign investing risk:&lt;/div&gt; The Income Fund may invest in securities that are not traded in the United States when market conditions or investment opportunities arise that, in the judgment of the adviser (Saturna Capital Corporation), warrant such investment. 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.&lt;/div&gt;

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.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;The Growth Fund does not make any investments that pay interest. Islamic principles discourage speculation, and the Fund tends to hold investments for several years.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;The Growth Fund diversifies its investments across industries and companies, and principally follows a large-cap value investment style. The Fund favors companies expected to grow earnings and stock prices faster than the economy. The Fund may also invest in smaller and less seasoned companies. The Fund seeks companies demonstrating both Islamic and sustainable characteristics. The Fund's adviser (Saturna Capital Corporation) 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.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;It is the policy of the Growth Fund, under normal circumstances, to invest at least 80% of total net assets in common stocks.

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.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Small-cap risk:&lt;/div&gt; The smaller and less seasoned companies that may be in the Growth Fund have a greater risk of price volatility. Growth stocks, which can be priced on future expectations rather than current results, may decline substantially when expectations are not met or general market conditions weaken.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Investment strategy risk:&lt;/div&gt; Islamic principles restrict the Growth 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.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Equity securities risk:&lt;/div&gt; 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. The Fund also tends to favor growth stocks, which tend to trade based on future earnings expectations, and may be more volatile than slower-growing value stocks, especially when market expectations are not met.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Foreign investing risk:&lt;/div&gt; The Growth Fund may invest in securities that are not traded in the United States when market conditions or investment opportunities arise that, in the judgment of the adviser (Saturna Capital Corporation), warrant such investment. 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.&lt;/div&gt;&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Technology sector risk:&lt;/div&gt; The Fund's investments in technology companies exposes the Fund to risks. For example, rapid advances in science and technology might cause existing products to become obsolete, and the Fund's returns could suffer to the extent it holds an affected company's shares. A number of technology companies engaged in consumer-facing activities are potentially subject to more aggressive government regulation and intervention in their traditional business activities. This fact may affect a company's overall profitability and cause its stock price to be more volatile. Additionally, technology companies are dependent upon consumer and business acceptance as new technologies evolve.&lt;/div&gt;</rr:RiskNarrativeTextBlock>

    <rr:StrategyNarrativeTextBlock contextRef="P05_31_2020To05_31_2020_S000026568MemberdeiLegalEntityAxis">&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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, Ecuador, Hungary, India, Indonesia,&lt;/div&gt;
&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;Jordan, Kuwait, Malaysia, Malta, Mexico, Oman, Panama, Peru, Philippines, Poland, Qatar, Russia, Saudi Arabia, Slovenia, South Africa, South Korea, Taiwan, Thailand, Turkey, Vietnam, and United Arab Emirates.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

    <rr:RiskNarrativeTextBlock contextRef="P05_31_2020To05_31_2020_S000026568MemberdeiLegalEntityAxis">&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Market risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Investment strategy risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Equity securities risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Foreign investing risk:&lt;/div&gt; 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.&lt;/div&gt;

    <rr:StrategyNarrativeTextBlock contextRef="P05_31_2020To05_31_2020_S000050991MemberdeiLegalEntityAxis">&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;Under normal conditions, the Participation Fund invests at least 80% of its total net assets in short and intermediate-term Islamic income-producing investments. 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).&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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. Some of the businesses not permitted are liquor, wine, casinos, pornography, insurance, gambling, pork processing, and interest-based banks or finance associations.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;In accordance with Islamic principles, the Fund shall not purchase conventional bonds, debentures, or other interest-paying obligations of indebtedness. Islamic principles discourage speculation, and 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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&lt;/div&gt;
&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;up to 35% in unrated and high-yield notes and certificates, which may be considered equivalent to "junk bonds."&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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 shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.&lt;/div&gt;

    <rr:RiskHeading contextRef="P05_31_2020To05_31_2020_S000050991MemberdeiLegalEntityAxis">Principal Risks of Investing</rr:RiskHeading>
    <rr:RiskNarrativeTextBlock contextRef="P05_31_2020To05_31_2020_S000050991MemberdeiLegalEntityAxis">&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Market risk:&lt;/div&gt; The value of Participation Fund shares rises and falls as the 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 and currency markets as well as the fortunes of the countries, industries, and companies in which the Fund invests.&lt;/div&gt;
&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Diversification and concentration risks:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Investment strategy risk:&lt;/div&gt; 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 income.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Liquidity risk:&lt;/div&gt; Liquidity risk exists when particular investments are difficult to sell. Investments by the Fund in foreign securities and those that are thinly traded, such as lower quality issuers, tend to involve greater liquidity risk. The market for certain investments may become illiquid under adverse market or economic conditions.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Foreign investing risk:&lt;/div&gt; The Participation 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. The risks of&#160;foreign investing are generally magnified in the smaller and more volatile securities markets of the Participation Fund.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Developing world risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Sukuk risk:&lt;/div&gt; 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.&lt;/div&gt;
&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Interest rate risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Credit risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;High-yield risk:&lt;/div&gt; 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Subsidiary Investment Risk:&lt;/div&gt; 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 premitted 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;&lt;div style="font-weight:bold;display:inline;width:100%;"&gt;Tax Risk:&lt;/div&gt; 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 sukuk, 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.&lt;/div&gt;

&lt;div style="margin-top: 1em; margin-bottom: 1em"&gt;The Internal Revenue Service ("IRS") has issued regulations providing that income inclusions from a RIC subsidiary such as the Subsidiary will constitute qualifying income for the RIC whether or not the income is distributed to the RIC. These regulations are consistent with the conclusions in private letter rulings the IRS had previously issued, and they remove the uncertainty that existed as a result of earlier proposed regulations providing that only distributions the subsidiary made to the RIC out of its earnings and profits for the applicable tax year would so qualify. 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 IRS that could affect whether income derived from such investments is "qualifying income" under Subchapter M of the Internal Revenue Code of 1986, as amended, or otherwise affect the character, timing, and/or amount of the Fund's taxable income or any gains or distributions made by the Fund.&lt;/div&gt;
