Statement of Additional Information Revisions

Effective September 28, 2026, pages 20-21 of the Funds' Statement of Additional Information are hereby striken and replaced with the following:

Portfolio Managers

All Saturna Capital employees, including Mr. Bryce R. Fegley, Ms. Elizabeth W. Alm, Mr.Patrick T. Drum, Mr. William B. Jones IV, Mr. Tae Han ("Simon") Kim, Mr. Jason Mitchell, Mr. Levi Stewart Zurbrugg, Mr. Rajasekhar Ravishankar, Mr. Pierce S. McCrerey, and other portfolio managers are paid an annual salary, as set by the board of Saturna Capital. Saturna Capital also pays bonuses that are partly dependent on the profits of Saturna Capital and may also reflect the results of specific managed accounts or specific businesses of Saturna Capital. As owners of shares and/or stock options of Saturna Capital Corporation, Ms. Alm and Messrs. Drum, Fegley, Jones IV, Kim, Mitchell, Zurbrugg, Ravishankar, and McCrerey, may benefit from any increase in its value per share that might result from its operations or profits. They may also receive dividends on shares of Saturna Capital. All Saturna Capital employees are eligible for a retirement plan, health care and other benefits, and a stock option plan. Stock options are annually awarded on the basis of years of service, and not individual performance. Mutual fund portfolio managers are compensated with salary and discretionary bonus based on quantitative and qualitative factors.

Saturna Capital's portfolio managers may manage multiple accounts, including mutual funds and separate accounts for individuals, investment partnerships, pension funds, and charities. Portfolio managers make investment decisions for each account based on the investment objectives, policies, practices, and other relevant investment considerations that the managers believe are applicable to that account. The management of multiple accounts may give rise to potential conflicts of interest when the accounts have similar or different objectives, benchmarks, time horizons, and fees because the portfolio manager must allocate their time and investment ideas across multiple accounts. Consequently, a manager may purchase (or sell) a security for one account and not for another. The adviser has adopted policies designed to fairly allocate securities purchased or sold on an aggregated basis. Transactions executed for one account may adversely affect the value of securities held by other accounts. Securities selected for some accounts may outperform the securities selected for others. A portfolio manager's compensation plan may give rise to potential conflicts of interest. To reduce this risk, a mutual fund portfolio manager's account performance bonus depends upon the Fund's overall Morningstar™ rating, which derives from investment results over the last three, five, and ten years. A manager's compensation tends to increase with assets under management, which in turn may increase the value of Saturna Capital Corporation.
