Portfolio Managers

All Saturna Capital employees, including Elizabeth W. Alm, Jane K. Carten, Patrick T. Drum, Bryce R. Fegley, William B. Jones IV, Tae Han "Simon" Kim, and other portfolio managers are paid an annual salary, as set by the board of Saturna Capital. The board 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, Mmes. Alm and Carten and Messrs. Drum, Fegley, Jones, Kim, and Zurbrugg, 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 paid a monthly bonus (which may be shared with other employees) when a Fund achieves an overall rating of 4 or 5 stars from Morningstar. The bonus is 1% of the adviser's net monthly fee (which is based on both assets and performance) for a 4-star rating and 2% of the monthly fee for a 5-star rating.

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.
