**Expenses Example**

The example below is intended to help investors compare the cost of investing in the Short-Term Bond Fund with the cost of investing in other mutual funds. 

The example assumes an investor invests $10,000 in the Short-Term Bond Fund for the time periods indicated and then redeems all shares at the end of those periods. The example also assumes that the investment has a 5% return each year and that the Fund's operating expenses remain the same. Although actual costs may be higher or lower, based on these assumptions an investor's costs would be:

| 1 year | 3 years | 5 years | 10 years |
|--------|---------|---------|----------|
| $136   | $425    | $734    | $1,613   |

### Portfolio Turnover Rate

During the most recent fiscal year, the Short-Term Bond Fund's portfolio turnover rate was 27% of the average value of its portfolio. The Fund buys and sells securities through Saturna Brokerage Services, Inc. (SBS), a wholly-owned subsidiary of Saturna Capital, which presently charges no commissions on portfolio trades.

### Principal Investment Strategies

The Short-Term Bond Fund invests at least 80% of its assets in short-term bonds. Under normal circumstances the Fund's dollar-weighted average maturity does not exceed three years. The Short-Term Bond Fund invests at least 65% of assets in bonds rated within the three highest grades (AAA, AA or A); and may not invest in a bond rated at time of purchase below the fourth highest grade (BBB).

### Principal Risks of Investing

The value of Short-Term Bond Fund shares rises and falls as the value of the bonds in which the Fund invests goes up and down. Only consider investing in the Fund if you are willing to accept the risk that you may lose money. Fund share prices, yields, and total returns will change with market fluctuations as well as the fortunes of the industries and companies in which the Fund invests.

The risks inherent in the Short-Term Bond Fund depend primarily on the terms and quality of the obligations in its portfolio, as well as on bond market conditions. When interest rates rise, bond prices fall. When interest rates fall, bond prices go up. Bonds with longer maturities usually are more sensitive to interest rate changes than bonds with shorter maturities, such as those held by the Short-Term Bond Fund. The Fund entails credit risk, which is the possibility that a bond will not be able to pay interest or principal when due. If the credit quality of a bond is perceived to decline, investors will demand a higher yield, which means a lower price on that bond to compensate for the higher level of risk.

### Performance

The following bar chart and table provide an indication of the risks of investing in the Short-Term Bond Fund by showing changes in performance from year to year and by showing how the Fund's average annual returns for 1, 5 and 10 years compare to those of a broad-based market index. A fund's past performance (before and after taxes) is not a guarantee of how a fund will perform in the future. Performance data current to the most recent month-end and quarter-end are available on www.sextantmutualfunds.com.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates but do not reflect the impact of any state or local taxes. Actual after-tax returns depend on an investor's tax situation and likely differ from those shown. After-tax illustrations are not relevant to retirement plans, corporations, trusts, or other investors that are taxed at special rates. In loss periods, the average after-tax total return may be higher than average annual total return because of an assumed deduction of losses from other income.
