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. To the extent prohibited by Islamic investment principles the Fund does not invest in companies primarily engaged in businesses such as alcohol, tobacco, pork products, pornography, interest-based banks, finance associations and insurers, weapons, and gambling. The Fund does not make any investments not permitted under Islamic principles, including those that pay interest. Islamic principles discourage speculation. The Fund tends to hold investments for several years. The Fund may invest its uninvested cash in short-term Islamic income-producing investments called murabaha and wakala, as described below. The Fund diversifies its investments across industries and companies, and principally follows a large-cap value investment style. As a result, the Fund favors companies expected to grow earnings and stock prices faster than the economy. The Fund's adviser (Saturna Capital Corporation) considers a company's past earnings and revenue growth rates, as well as the expectation of increases in earnings and share price. The Fund may also invest in smaller and less seasoned companies. The Fund seeks companies demonstrating both Islamic and sustainable characteristics. The Funds adviser considers issuers with sustainable characteristics to be those issuers that are more established, consistently profitable, and financially strong, with robust policies in the areas of the environment, social responsibility, and corporate governance (collectively referred to as Sustainability). Except for murabaha and wakala investments, the adviser employs a sustainable rating system based on its own, as well as third-party, data to identify issuers believed to have lower Sustainability risks. The use of third-party data does not include third-party environmental, social, or governance ("ESG") ratings or criteria established by third parties for third-party ratings. The advisers proprietary scoring system assesses how well a company performs relative to a blend of its industry, sector, and country peers. In addition to the financial considerations discussed above, the adviser considers sustainability practices such as carbon emissions, water usage, renewable energy, and fair labor and supply chain practices. The Funds Sustainability evaluation process considers risks and opportunities holistically, meaning an issuer will not necessarily be excluded from investment due to any one particular factor if the overall analysis results in a favorable evaluation by the adviser. The adviser also uses negative screening to exclude companies primarily engaged in higher Sustainability risk businesses, such as companies in the business of fossil fuel exploration, production, or refining, and, to the extent prohibited by Islamic investment principles, companies primarily engaged in businesses such as alcohol, tobacco, pork products, pornography, interest-based banks, finance associations and insurers, weapons, and gambling. It is the policy of the Fund, under normal circumstances, to invest at least 80% of total net assets in common stocks (the 80% Policy). Because Islamic principles preclude the use of interest-paying instruments, the Funds cash positions do not earn interest income. The Fund may invest its cash positions in murabaha and wakala, which are notes and certificates issued for payment by foreign governments, their agencies, and financial institutions in transactions structured to be in accordance with Islamic principles. Murabaha involves a purchase and sale contract, and wakala involves the operation of an account 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 Funds investment in the notes and certificates. In addition, the Fund may invest cash positions in time deposits with banks that involve underlying purchase and sale agreements to generate the return on the deposit. The Fund will seek to gain exposure to murabaha and wakala investments by investing up to 20% of the Funds total net assets in a wholly-owned and controlled subsidiary, which is organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary invests in murabaha and wakala investments and may invest in other short-term Islamic income-producing investments. The Fund invests in the Subsidiary in order to gain exposure to murabaha and wakala investments within the limitations of the federal tax law, rules and regulations that apply to regulated investment companies.
