The Fund seeks to attain its investment objective by investing in short-term money-market securities denominated in U.S. dollars that are of high quality and present minimal credit risks. Under the current management policies, the Fund invests primarily in the following types of obligations:

(5) Municipal 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.

(7) Refunded Securities, which are debt securities the principal and interest of which are paid by “Government Securities” (as defined in the Investment Company Act of 1940 as amended (the “1940 Act”)) that have been placed in an escrow account and pledged only to the payment of the debt security. In general, Government Securities are those the principal and interest of which are paid by or are guaranteed by the U.S. Government or its instrumentalities. The Fund will invest only in Refunded Securities meeting the applicable requirements of Rule 5b-3 under the 1940 Act.

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.

Structured Securities Risk. The payment and credit qualities of structured securities derive 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 obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Foreign Securities Risk. Foreign securities are subject to a number of additional risks, including nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, political or financial instability and other adverse economic or political developments. Lack of information and less market regulation may also affect the value of these securities.

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 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 1.27% (quarter ended March 31, 2001) and the lowest return for a quarter was 0.01% (quarter ended June 30, 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.

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.
