Aquila Investment Management LLC manages, markets and administers mutual funds. Aquila Investment Management LLC is a wholly-owned subsidiary of Aquila Management Corporation, founder and sponsor of the Aquila Group of Funds. Aquila Distributors, Inc., an affiliate, distributes shares for each of the Aquila-sponsored funds.

The Aquila Group of Funds has combined assets of $3.2 billion. The Aquila Group of Funds primarily specializes in fixed income investments. It currently consists of 9 funds: 7 single state municipal bond funds, a high yield corporate bond fund and an equity fund.

Aquila's 7 municipal bond funds serve investors in states with smaller populations, relatively high income tax rates and interesting long term economic growth potential - Arizona, Colorado, Hawaii, Kentucky, Oregon, Rhode Island and Utah. Aquila is generally unique in four local aspects of these funds:

* locally-based portfolio management

* locally-based Trustees

* locally-based Officers who provide dedicated in-state service to the brokerage community and individual investors and

* locally-based shareholder meetings.

Aquila's niche marketing and localized approach has gained a prominent position for each of the 7 municipal bond funds in their respective states.

A commitment to extensive fundamental research and a detailed knowledge of corporate issuers and credits are hallmarks of the high yield corporate bond fund, Aquila Three Peaks High Income Fund.

While conducting in-depth research on high-yield corporate bond issuers, we also search for growth opportunities suited to our distinctive equity fund, Aquila Three Peaks Opportunity Growth Fund.

Diana P. Herrmann is Vice Chair, President, and Chief Executive Officer of Aquila Investment Management LLC and is President and Trustee of each of the funds.

Risk Factors: Municipal Bond Funds: An investment involves certain risks including potential loss of value, market risk, interest rate risk, credit risk, and geographic concentration. Insurance on an obligation is intended to mitigate credit risk; it does not insure the market price of the obligation. For certain investors, some dividends may be subject to Federal and state taxes, including Alternative Minimum Tax (AMT). Corporate Bond Fund: This Fund may invest up to 100% of its assets in high-yield bonds that are rated below investment grade. Lower rated bonds generally offer higher yields, but also involve a greater degree of credit risk and default risk than higher rated bonds. The return of principal for the bond holdings in this fund is not guaranteed. Equity Fund: An investment in the Fund involves certain risks, including possible loss of value, market and financial risk, volatility and trading volume of small companies, interest & credit risks of convertible fixed-income investments, economic and diversification risks of geographic concentration.
