The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund seeks to attain its investment objective by investing in municipal obligations of Hawaiian issuers to the extent that obligations of the desired quality, maturity and interest rate are available; otherwise by investing in similar obligations of non-Hawaii issuers. These obligations must have remaining maturities not exceeding 397 days, must be of high quality and must present minimal credit risks. At least 80% of the Tax-Free Fund’s assets must be invested in Municipal Obligations (as defined below).

The term “Municipal Obligations” is used to mean obligations with maturities of 397 days or less paying interest which, in the opinion of bond counsel or other appropriate counsel, is exempt from regular Federal income taxes. “Hawaiian Obligations” are Municipal Obligations, including those of Guam, the Northern Mariana Islands, Puerto Rico and the Virgin Islands, paying interest which, in the opinion of bond counsel or other appropriate counsel, is also exempt from Hawaii state income taxes.

Since it is not possible to predict the extent to which suitable Hawaiian Obligations will be available for investment, the Tax-Free Fund has no investment restriction limiting the proportion of its portfolio which it may invest in other Municipal Obligations.

Municipal Obligations are debt obligations issued by or on behalf of states, cities, municipalities and other public authorities. These securities include participation or other interests in municipal securities and other structured securities such as variable rate demand obligations, tender option bonds, partnership interests and swap-based securities, many of which may be issued or backed by U.S. or non-U.S. banks. Some Municipal Obligations, such as general obligation issues, are backed by the issuer’s taxing authority, while other Municipal Obligations, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself.

An investment in the Fund is not a deposit in, nor endorsed or guaranteed by, any bank, and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Market and Interest Rate Risk. There may be changes in interest rates, lack of liquidity or other disruptions in the bond markets or other adverse market events and conditions. Such conditions have contributed to a low rate environment resulting in historically low yields returned by money market funds. As these conditions persist, investors should be aware that the yield or return for the Fund could remain extremely low.

Credit Risk. An issuer or obligor of a security held by the Fund or a counterparty to a financial contract with the Fund may default or its credit may be downgraded, or the value of assets underlying a security may decline.

Yield Risk. The amount of income received by the Fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the Fund’s expenses could absorb all or a significant portion of the fund’s income. If interest rates increase, the Fund’s yield may not increase proportionately. For example, the Fund’s Adviser or Administrator may discontinue their current voluntary fee waivers. In addition, the recent adoption of more stringent regulations governing the management of money market funds could have a negative effect on the Fund’s yield.

Risk of Increase in Expenses. Your actual costs of investing in the Fund may be higher than the expenses shown in “Annual Fund Operating Expenses” for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease or are lower than estimated, or if a fee limitation or waiver is changed or terminated.

Tax Risk. The income on the Fund’s Municipal Obligations could become subject to Federal and/or state income taxes due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities.

Structured Securities Risk. The payment and credit qualities of structured securities are derived from their embedded assets, and they may behave in ways not anticipated by the Fund, or they may not receive tax, accounting or regulatory treatment anticipated by the Fund.

Risks Associated with Concentration in the Banking Industry. The Fund may invest a significant portion of its assets in municipal securities and interests in municipal securities that are issued or backed by U.S. and non-U.S. banks, and thus may be more susceptible to negative events affecting the worldwide banking industry.

Redemption Risk. The Fund may experience heavy redemptions, particularly during periods of declining or illiquid markets, that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and that could affect the Fund’s ability to maintain a $1.00 share price. In addition, the Fund may suspend redemptions when permitted by applicable regulations.

The Fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in one issuer than a diversified fund. However, the Fund intends to comply with the diversification requirements applicable to money market funds which limit the Fund’s ability to invest in the obligations of a single issuer.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing the Fund’s average annual returns for the designated periods. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.aquilafunds.com or by calling 800-437-1020 (toll-free).

During the period shown in the bar chart, the highest return for a quarter was 0.80% (quarter ended March 31, 2001) and the lowest return for a quarter was 0.00% (quarter ended December 31, 2010). Investors should be mindful that the return of the Fund will remain extremely low as long as the current economic conditions fostering a low rate environment persist.

You may purchase, redeem or exchange shares of the Fund on any day the New York Stock Exchange is open for business. You may purchase, redeem or exchange Service Shares either through a financial advisor or directly from the Fund. Subject to certain limited exceptions, Original Shares may be purchased, redeemed or exchanged only through a financial intermediary. The minimum initial purchase into the Fund is $1,000, and $50 if an automatic investment program is established. There is no minimum for subsequent investments.

The Fund intends to distribute income that is exempt from regular Federal income taxes, and, to the extent derived from Hawaiian Obligations, from Hawaii state income taxes. Portions of the Fund’s distributions may be subject to such taxes and/or to the Federal alternative minimum tax.

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund and its Distributor or Administrator may pay the intermediary for the sale of Fund shares and related shareholder servicing activities. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
