Idaho Tax-Exempt Fund
November 30, 1999 Report

Fellow Shareowners:

For the twelve month period ending November 30, 1999, the Idaho Tax-Exempt Fund provided a total return of ­2.18%. The current 30-day yield on your Fund is 4.80%, tax-free. This tax-free yield converts to a fully-taxable equivalent yield of 8.73% for top-bracket Idaho taxpayers. During the year, Fund assets decreased 2.2% to $ 6.15 million while the Fund's expense ratio held steady at 0.80%.

The booming expansion of the US economy set the tone for bond markets in 1999. Record employment, rising wages and a near tripling of oil prices kept Federal Reserve Bank policy on the defensive all year. The Federal Reserve Bank raised its target for Fed Funds by .75% to prevent an increase in the US inflation rate. To date, the increase in rates appears to have restrained inflation without hurting the economy.

The damaging potential of these events inspired us to keep the Fund's effective average maturity close to its five year minimum to reduce risk. As a result, Idaho Tax-Exempt Fund's ­2.18% one-year return compares favorably, for example, with the ­3.63% one-year return of comparable U.S. Treasuries. We have now extended the effective average maturity to 10.2 years to take advantage of higher rates. We were able to improve the average credit quality of the Fund slightly.

Since 1993, the interest rates have moved within a well-defined range. Today, intermediate term yields rest at the mid-point of that range. For the next year, we expect inflation to remain modest. With today's higher rates, the potential for positive real returns in Idaho Tax-Exempt Fund appear brighter than one year ago.

As always, our staff and portfolio managers welcome your comments and suggestions. Only with your help can we be certain that we are meeting your investment needs our primary objective. We appreciate your investing with us.

Morningstar Mutual Funds has awarded Idaho Tax-Exempt Fund a "four star" rating as of November 30, 1999. The Morningstar rating is a widely respected measure of historical risk-adjusted performance. The ratings are subject to change each month, and are calculated from a fund's 3 and 5-year average annual returns with sales charge adjustments (if any) and a risk factor that reflects performance relative to 3-month Treasury Bill returns. Twenty percent of the funds in a Morningstar investment category receive four stars, the second-highest rating. The adviser has waived a portion of its fee in past years, resulting in higher returns. Naturally, past performance may not indicate future results.

DISCUSSION of FUND PERFORMANCE
(unaudited)

For the year ending November 30, 1999, Idaho Tax-Exempt Fund returned shareowners -2.18%, our worst year since 1994. As of November 30, 1999 the thirty-day yield for the Fund was 4.80% or 0.79% higher than one year ago. Fund assets decreased 2% to $6.15 million, and the Fund's expense ratio remained at 0.80%.

1999, like 1994, was a year when the Federal Reserve Bank pursued aggressive anti-inflationary policies. High U.S. economic growth, rising employment, rising wages and a near tripling of oil prices left few alternatives. The economy was not going to slow down on it's own. The Federal Reserve increased its target for federal funds by ³/₄% despite a surge in productivity and highly competitive global pricing.

The primary objective of the Fund is current income exempt from federal and Idaho personal income taxes. As the yield advantage and supply of uninsured bonds continues to dwindle, we have continued to increase the average credit quality of the Fund. 13% of the portfolio remains invested in non-rated bonds, down slightly from 14% twelve months ago. 46% of the Fund is now invested in insured bonds.

The secondary objective of the Fund is capital preservation. The average maturity of the Fund is the most important factor affecting principal values in the portfolio. Having recognized the potential for higher rates early in the year, we kept the average effective average maturity of the fund close to it's five-year minimum to reduce risk. However, municipal rates have now risen as much as 0.90% and we believe the 8-12 year area of the yield curve now offers the best combination of risk and return. We have lengthened the effective average maturity of the Fund to 10 years. We expect to maintain an average effective portfolio maturity in the same range over the next year.

The economy of Idaho recovered in 1999 after a soft 1998 and weak 1997. The state's diversification away from resource based industries into high technology, communications, services, tourism and new areas in agriculture all helped. Commercial and residential construction turned out to be less susceptible to rising interest rates than expected. Employment, personal income and population all show improvement. Growth continues concentrated along the corridor between Boise and Idaho Falls.

Idaho's high state personal income taxes create a substantial appetite among residents for tax-exempt bonds. Idaho municipal bonds benefit from an imbalance between the number of buyers and the number of issues available. This imbalance is important in weak markets like 1999 and 1994, when Idaho bonds outperform issues from other states. The Fund's -2.18% one-year return compares favorably, for example, with the -3.63% one-year return of intermediate U.S. Treasury notes. Idaho's record of repaying municipal debt remains unblemished, which also adds to investors' appetites.

Though the Fund does not try to "beat" the Lehman Brothers Municipal Bond Index or any other specific index, the Fund's returns, considering the lower price fluctuation, compare well to that of the Index for the fiscal year. The graph compares the Idaho Tax-Exempt Fund's performance to the performance of the Lehman Brothers Composite Municipal Bond Index, a broad-based municipal bond market index. To be comparable, the Municipal Index data includes reinvested income (as computed by Lehman Brothers Fixed Income Research).

Note that this graph compares an unmanaged, expense-free index to an actively managed Fund that has transaction and other costs. The Fund stands ready to buy and sell its own shares on a daily basis, and provides numerous investor services. Few investors are able to invest in an exact index portfolio because of the large amount of securities required to model such an index.

Were the Fund to target the index as an objective, the Fund might take greater risk by extending the average maturity of its portfolio to take advantage of the greater price fluctuation (for better or worse) available in such a portfolio. However, maintaining the stability of capital is an objective of the portfolio, and we believe the Fund has performed well considering its investment restrictions.

The graph shows that $10,000 invested in the Idaho Tax-Exempt Fund ten years ago (end of November 1989) would have grown to $17,153 at the end of November 1999. If the $10,000 could have been invested in the Lehman Brothers Composite Municipal Bond Index at the end of November 1989, it would have grown to $19,781.

Note 1-Organization
Saturna Investment Trust, (formerly Northwest Investors Trust) Trust (the "Trust") was established under Washington State Law as a Business Trust on February 20, 1987. The Trust is registered as a no-load, open-end series investment company under the Investment Company Act of 1940, as amended. Four portfolios have been created to date in addition to Idaho Tax-Exempt Fund (the "Fund"). The other four portfolios distribute through a separate prospectus and the results of those funds are contained in a separate report.

Note 2--Significant Accounting Policies
The following is a summary of the significant accounting policies followed by the Fund.

Investments:
Fixed-income securities for which there are no publicly available market quotations are valued using matrices based on maturity, quality, industry, yield, call features and similar factors, which are compared periodically to multiple dealer bids and adjusted by the adviser under policies established by the Trustees.

The cost of securities is the same for accounting and Federal income tax purposes. Securities transactions are recorded on trade date. Realized gains and losses are recorded on the identified cost basis.

Income and Expenses:
Interest income is reduced by the amortization of bond premiums, on a constant yield basis from purchase date to maturity or expected call date, whichever is earlier.

Interest income is increased by accretion only for bonds underwritten as original issue discounts. Market discounts are recorded as realized gains upon disposition.

Expenses incurred by the Trust on behalf of the Fund (e.g., professional fees) are allocated to the Fund and the other Funds of the Trust on the basis of relative daily average net assets. The Adviser has agreed to certain limits on expenses, as described below.

Income taxes:
The Fund has elected to be taxed as a regulated investment company under the Internal Revenue Code and distribute substantially all of its taxable net investment income and realized net gains on investments. Therefore, no provision for Federal income taxes is required. Further, the Fund intends to meet IRS requirements for tax-free income dividends, and requirements of the Idaho Department of Revenue for income dividends free of Idaho state income tax.

Dividends and distributions to shareowners:
Dividends and distributions to shareowners are recorded on the ex-dividend date. Dividends are paid daily and distrib

uted on the last business day of each month. Shareowners electing to reinvest dividends and distributions purchase additional shares at the net asset value on the payable date.

Note 3--Transactions with Affiliated Persons
Under a contract approved by shareowners on October 12, 1990, Saturna Capital Corporation provides investment advisory services and certain other administrative and distribution services to conduct the Fund's business. For such services, the Fund pays an annual fee equal to 0.50% of average daily net assets. For the year ended November 30, 1999, the Fund incurred advisory fee expenses of $31,859.

Saturna Capital has volunteered to reimburse the Fund to the extent that total expenses of the Fund (excluding interest, brokerage commissions and taxes) exceeds 0.80% through March 31, 2000. Accordingly, for the year ended November 30, 1999, Saturna Capital waived $1,052 of the advisory fee.

In accordance with the Fund's agreement with its custodian bank, National City Bank of Indiana, for the year ended November 30, 1999, custodian fees incurred by the Fund amounted to $1,867. The custodian waived its fees for earnings credits.

One trustee and shareowner also serves as president of the Trust and is a director and president of Saturna Capital Corporation.

The Trust acts as a distributor of its own

shares, except in those states in which Investors National Corporation (a subsidiary of Saturna Capital Corporation) is itself registered as a broker-dealer, where it acts as distributor without compensation. Saturna Capital Corporation acts as shareowner servicing (transfer) agent for the Fund, for a monthly fee plus certain expenses. For the fiscal year ended November 30, 1999, the Fund paid such a fee of $4,049.

Unaffiliated trustees receive a fee of $100 per meeting attended, allocated pro-rata to the five Funds of Saturna Investment Trust. On November 30, 1999, the trustees, officers and their immediate families as a group owned 0.1% of the outstanding shares of the Fund.
