While there is a plethora of information available on these topics and others if you are interested, the good news is that when it comes to Narragansett Insured Tax-Free Income Fund you don't need to be versed in "financialese" any more than you wish. Why? Because one of the conveniences afforded you through an investment in Narragansett Insured Tax-Free Income Fund is local active professional portfolio management. The Fund's portfolio managers continuously monitor economic, monetary and financial trends and adjust the portfolio accordingly as and when they deem appropriate. Your Fund's portfolio managers provide ongoing surveillance of the marketplace and strive to maneuver cautiously through its ups and downs - much like a ship's captain whose job it is to ride out sudden storms. Not unlike the prudent ship's captain who ensures that the cargo is properly balanced and positioned, the Fund's portfolio managers are constantly monitoring the investment portfolio and the economic weather conditions striving to provide as stable a net asset value and as high a level of tax-free income as possible. As with a ship in choppy seas, your investment requires constant vigilance and nimble reflexes in all phases of its management. This does not, however, NOT A PART OF THE ANNUAL REPORT mean selling and buying securities continuously based upon market blips. What it does mean is being a keen observer of the scene, monitoring securities very carefully and taking action as appropriate whenever significant changes occur or are anticipated. Your portfolio managers seek opportunities that make sense within the prevailing marketplace and which provide double tax-free income while maintaining the overall conservative nature of the portfolio. In short, your professional managers do the work for you. So, the next time you come across a boring, complex analysis of the bond market, feel free to flip right past it. Your Fund's portfolio management team's job (and their passion) is to keep on top of and make sense out of all the news. Thus, like a seasoned traveler, you can enjoy your trip knowing that there are experienced eyes watching the waters and steady hands on the helm. Sincerely, /s/ Lacy B. Herrmann /s/ Diana P. Herrmann Lacy B. Herrmann Diana P. Herrmann Founder and Chairman Emeritus President NOT A PART OF THE ANNUAL REPORT [LOGO OF NARRAGANSETT INSURED TAX-FREE INCOME FUND: RECTANGLE WITH PROFILE VIEW OF A SAILBOAT ON TOP OF WAVES AND THREE SEAGULLS FLYING ABOVE IT] SERVING RHODE ISLAND INVESTORS FOR 15 YEARS NARRAGANSETT INSURED TAX-FREE INCOME FUND ANNUAL REPORT MANAGEMENT DISCUSSION Narragansett Insured Tax-Free Income Fund (the "Fund") seeks to provide the highest level of double tax-free income possible while staying within its self-imposed quality restraints. The Fund strives to accomplish this by purchasing only municipal securities rated AAA by nationally renowned credit rating services. As an extra measure of credit protection to shareholders, all securities owned by the Fund are insured to provide for the timely payment of principal and interest when due. A maximum average maturity profile of less than 12 years has been and will likely continue to be maintained for the Fund's portfolio in order to produce a reasonable level of income return with relatively high stability for the Fund's share price. At the June 30, 2007 fiscal year end, the portfolio had an average maturity of 8.7 years. Equity markets have surprised many investors as all major U.S. equity markets have performed well year to-date through June, 2007. The S&P 500, Dow Jones Industrials, and NASDAQ indices were up 7.0%, 8.8%, and 8.2%, respectively. International equity markets have fared even better than U.S. markets as Europe, China, and Japan have continued to expand at unanticipated levels. The broad market Europe, Australia, and Far East ("EAFE") index showed a return of 11.2% for the same time period. The pace of potential mergers and continued stock buy back programs has helped propel the equity markets in addition to decent earnings announcements across the board. The only thing that appears to be in the way of further gains is the drag from the slowing home building market, which has yet to be reflected in recent consumer spending figures. Should a prolonged downturn exist because of fallout from the much publicized home foreclosures and credit card delinquencies, we would not be surprised to see a correction in the equity market. It has been exactly one year since the last interest rate hike and the Federal Reserve (the "Fed") has remained on hold with the Federal Funds target rate set at 5.25%. The Fed's concern generally continues to be inflation as measured by Personal Consumption Expenditure ("PCE"). In addition, the Fed has kept close tabs on the core Consumer Price Index ("CPI") and labor costs, the latter of which has been deemed to have been particularly stubborn. The Fed has also not been shy about its intention to raise rates further if inflation remains elevated. In response, U.S. Treasury yields have moved to over 5% and the yield curve has begun to show a positive slope. Further competition from foreign markets has also had an impact on yields of U.S. Treasury securities. Recent rates hikes by the European Central Bank and others have begun to bring world rates more in line with the U.S. This has started some reallocation of bond purchases to other markets outside of the U.S. This means that there is now more competition for capital, and we expect Treasury rates to adjust when fixed income investors make their allocations. MANAGEMENT DISCUSSION (CONTINUED) Given the current Federal and Rhode Island income tax rates, we believe Narragansett Insured Tax-Free Income Fund presently produces an attractive yield for Rhode Island residents when compared to taxable fixed-income securities. Management believes that having available to the Fund a locally-based investment manager, with extensive knowledge and experience in the Rhode Island municipal market, continues to add considerable value to the portfolio and provides a distinct benefit to the Fund's shareholders. The Fund's investment Sub-Adviser intends to continue to oversee the portfolio with a strong emphasis on achieving a balance between share price stability, acceptable double tax-free income return, and the highest standards of credit quality. PERFORMANCE REPORT The following graph illustrates the value of $10,000 invested in the Class A shares of Narragansett Insured Tax-Free Income Fund for the 10-year period ended June 30, 2007 as compared with the Lehman Brothers Quality Intermediate Municipal Bond Index and the Consumer Price Index (a cost of living index). The performance of each of the other classes is not shown in the graph but is included in the table below. It should be noted that the Lehman Index does not include any operating expenses nor sales charges and being nationally oriented, does not reflect state specific bond market performance.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for each of the years in the three year period ended June 30, 2005 have been audited by other auditors, whose report dated August 12, 2005 expressed an unqualified opinion on such financial highlights. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of June 30, 2007, by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Narragansett Insured Tax-Free Income Fund as of June 30, 2007, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

NARRAGANSETT INSURED TAX-FREE INCOME FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2007 1. ORGANIZATION Narragansett Insured Tax-Free Income Fund (the "Fund"), a non-diversified, open-end investment company, was organized on January 22, 1992 as a Massachusetts business trust and commenced operations on September 10, 1992. The Fund is authorized to issue 80,000,000 shares and, since its inception to May 1, 1996, offered only one class of shares. On that date, the Fund began offering two additional classes of shares, Class C and Class Y Shares. All shares outstanding prior to that date were designated as Class A Shares and are sold with a front-payment sales charge and bear an annual distribution fee. Class C Shares are sold with a level-payment sales charge with no payment at time of purchase but level service and distribution fees from date of purchase through a period of six years thereafter. A contingent deferred sales charge of 1% is assessed to any Class C shareholder who redeems shares of this Class within one year from the date of purchase. Class C Shares, together with a pro-rata portion of all Class C Shares acquired through reinvestment of dividends and other distributions paid in additional Class C Shares, automatically convert to Class A Shares after 6 years. The Class Y Shares are only offered to institutions acting for an investor in a fiduciary, advisory, agency, custodian or similar capacity and are not offered directly to retail investors. Class Y Shares are sold at net asset value without any sales charge, redemption fees, contingent deferred sales charge or distribution or service fees. On October 31, 1997, the Fund established Class I Shares, which are offered and sold only through financial intermediaries and are not offered directly to retail investors. Class I Shares are sold at net asset value without any sales charge, redemption fees, or contingent deferred sales charge. Class I Shares carry a distribution fee and a service fee. All classes of shares represent interests in the same portfolio of investments and are identical as to rights and privileges and differ with respect to the effect of sales charges, the distribution and/or service fees borne by each class, expenses specific to each class, voting rights on matters affecting a single class and the exchange privileges of each class. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America for investment companies. a) PORTFOLIO VALUATION: Municipal securities which have remaining maturities of more than 60 days are valued each business day based upon information provided by a nationally prominent independent pricing service and periodically verified through other pricing services. In the case of securities for which market quotations are readily available, securities are valued by the pricing service at the mean of bid and asked quotations. If market quotations or a valuation from the pricing service is not readily available, the security is valued at fair value determined in good faith under procedures established by and under the general supervision of the Board of Trustees. Securities which mature in 60 days or less are valued at amortized cost if their term to maturity at purchase is 60 days or less, or by amortizing their unrealized appreciation or depreciation on the 61st day prior to maturity, if their term to maturity at purchase exceeds 60 days. b) SECURITIES TRANSACTIONS AND RELATED INVESTMENT INCOME: Securities transactions are recorded on the trade date. Realized gains and losses from securities transactions are reported on the identified cost basis. Interest income is recorded on the accrual basis and is adjusted for amortization of premium and accretion of original issue and market discount. c) FEDERAL INCOME TAXES: It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions of the Internal Revenue Code applicable to certain investment companies. The Fund intends to make distributions of income and securities profits sufficient to relieve it from all, or substantially all, Federal income and excise taxes. d) MULTIPLE CLASS ALLOCATIONS: All income, expenses (other than class-specific expenses), and realized and unrealized gains or losses are allocated daily to each class of shares based on the relative net assets of each class. Class-specific expenses, which include distribution and service fees and any other items that are specifically attributed to a particular class, are charged directly to such class. e) USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. f) ACCOUNTING PRONOUNCEMENTS: In July 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required to be implemented no later than December 31, 2007 and is to be applied to all open tax years as of that date. At this time, management does not believe the adoption of FIN 48 will result in any material impact on the Fund's financial statements. In September 2006, FASB issued FASB Statement No. 157, "Fair Value Measurement" ("SFAS 157"), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Fund believes adoption of SFAS 157 will have no material impact on the Fund's financial statements. 3. FEES AND RELATED PARTY TRANSACTIONS a) Management Arrangements: Aquila Investment Management LLC (the "Manager"), a wholly-owned subsidiary of Aquila Management Corporation, the Fund's founder and sponsor, serves as the Manager for the Fund under an Advisory and Administration Agreement with the Fund. The portfolio management of the Fund has been delegated to a Sub-Adviser as described below. Under the Advisory and Administration Agreement, the Manager provides all administrative services to the Fund, other than those relating to the day-to-day portfolio management. The Manager's services include providing the office of the Fund and all related services as well as overseeing the activities of the Sub-Adviser and managing relationships with all the various support organizations to the Fund such as the shareholder servicing agent, custodian, legal counsel, fund accounting agent, auditor and distributor. For its services, the Manager is entitled to receive a fee which is payable monthly and computed as of the close of business each day at the annual rate of 0.50% on the Fund's average net assets. Citizens Investment Advisors, a department of Citizens Bank of Rhode Island (the "Sub-Adviser") serves as the Investment Sub-Adviser for the Fund under a Sub-Advisory Agreement between the Manager and the Sub-Adviser. Under this agreement, the Sub-Adviser continuously provides, subject to oversight of the Manager and the Board of Trustees of the Fund, the investment program of the Fund and the composition of its portfolio, arranges for the purchases and sales of portfolio securities, and provides for daily pricing of the Fund's portfolio. For its services, the Sub-Adviser is entitled to receive a fee from the Manager which is payable monthly and computed as of the close of business each day at the annual rate of 0.23% on the Fund's average net assets. For the year ended June 30, 2007, the Fund incurred management fees of $762,636 of which $534,974 was waived. The Manager has contractually undertaken to waive fees and/or reimburse Fund expenses during the period July 1, 2006 through June 30, 2007 so that total Fund expenses would not exceed 0.85% for Class A Shares, 1.70% for Class C Shares, 1.02% for Class I Shares or 0.70% for Class Y Shares. Under a Compliance Agreement with the Manager, the Manager is compensated for Chief Compliance Officer related services provided to enable the Fund to comply with Rule 38a-1 of the Investment Company Act of 1940. Specific details as to the nature and extent of the services provided by the Manager and the Sub-Adviser are more fully defined in the Fund's Prospectus and Statement of Additional Information. b) Distribution and Service Fees: The Fund has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1 (the "Rule") under the Investment Company Act of 1940. Under one part of the Plan, with respect to Class A Shares, the Fund is authorized to make distribution fee payments to broker-dealers or others ("Qualified Recipients") selected by Aquila Distributors, Inc., ("the Distributor"), including, but not limited to, any principal underwriter of the Fund, with which the Distributor has entered into written agreements contemplated by the Rule and which have rendered assistance in the distribution and/or retention of the Fund's shares or servicing of shareholder accounts. The Fund makes payment of this service fee at the annual rate of 0.15% of the Fund's average net assets represented by Class A Shares. For the year ended June 30, 2007, distribution fees on Class A Shares amounted to $154,124, of which the Distributor retained $4,386. Under another part of the Plan, the Fund is authorized to make payments with respect to Class C Shares to Qualified Recipients which have rendered assistance in the distribution and/or retention of the Fund's Class C Shares or servicing of shareholder accounts. These payments are made at the annual rate of 0.75% of the Fund's average net assets represented by Class C Shares and for the year ended June 30, 2007 amounted to $115,372. In addition, under a Shareholder Services Plan, the Fund is authorized to make service fee payments with respect to Class C Shares to Qualified Recipients for providing personal services and/or maintenance of shareholder accounts. These payments are made at the annual rate of 0.25% of the Fund's average net assets represented by Class C Shares and for the year ended June 30, 2007, amounted to $38,457. The total of these payments with respect to Class C Shares amounted to $153,829, of which the Distributor retained $38,573. Under another part of the Plan, the Fund is authorized to make payments with respect to Class I Shares to Qualified Recipients. Class I payments, under the Plan, may not exceed, for any fiscal year of the Fund a rate (currently 0.20%) set from time to time by the Board of Trustees of not more than 0.25% of the average annual net assets represented by the Class I Shares. In addition, the Fund has a Shareholder Services Plan under which it may pay service fees (currently 0.15%) of not more than 0.25% of the average annual net assets of the Fund represented by Class I Shares. That is, the total payments under both plans will not exceed 0.50% of such net assets. For the year ended June 30, 2007, these payments were made at the average annual rate of 0.35% of such net assets amounting to $2,622 of which $1,498 related to the Plan and $1,124 related to the Shareholder Services Plan. Specific details about the Plans are more fully defined in the Fund's Prospectus and Statement of Additional Information. Under a Distribution Agreement, the Distributor serves as the exclusive distributor of the Fund's shares. Through agreements between the Distributor and various broker-dealer firms ("dealers"), the Fund's shares are sold primarily through the facilities of these dealers having offices within Rhode Island, with the bulk of sales commissions inuring to such dealers. For the year ended June 30, 2007, total commissions on sales of Class A Shares amounted to $121,372, of which the Distributor received $12,009. c) Other Related Party Transactions: For the year ended June 30, 2007, the Fund incurred $68,894 of legal fees allocable to Hollyer Brady Barrett & Hines LLP ("Hollyer Brady") and its successor, Butzel Long PC, counsel to the Fund, for legal services in conjunction with the Fund's ongoing operations. The Secretary of the Fund was a partner at Hollyer Brady and is a shareholder of its successor. 4. PURCHASES AND SALES OF SECURITIES During the year ended June 30, 2007, purchases of securities and proceeds from the sales of securities aggregated $3,586,810 and $9,039,838, respectively. At June 30, 2007, the aggregate tax cost for all securities was $146,802,468. At June 30, 2007, the aggregate gross unrealized appreciation for all securities in which there is an excess of value over tax cost amounted to $2,391,145 and aggregate gross unrealized depreciation for all securities in which there is an excess of tax cost over value amounted to $922,937, for a net unrealized appreciation of $1,468,208. 5. PORTFOLIO ORIENTATION Since the Fund invests principally and may invest entirely in double tax-free municipal obligations of issuers within Rhode Island, it is subject to possible risks associated with economic, political, or legal developments or industrial or regional matters specifically affecting Rhode Island and whatever effects these may have upon Rhode Island issuers' ability to meet their obligations. However, to mitigate against such risks, the Fund has chosen to have at least 80% and possibly the entire number of issues in the portfolio insured as to timely payment of principal and interest when due by nationally prominent municipal bond insurance companies. At June 30, 2007, all of the securities in the Fund were insured. While such insurance protects against credit risks with portfolio securities, it does not insure against market risk of fluctuations in the Fund's share price and income return. The Fund is also permitted to invest in U.S. territorial municipal obligations meeting comparable quality standards and providing income which is exempt from both regular Federal and Rhode Island income taxes. The general policy of the Fund is to invest in such securities only when comparable securities of Rhode Island issuers are not available in the market. At June 30, 2007, the Fund had all of its net assets invested in Rhode Island municipal issues. 6. Expenses The Fund has negotiated an expense offset arrangement with its custodian wherein it receives credit toward the reduction of custodian fees and other Fund expenses whenever there are uninvested cash balances. The Statement of Operations reflects the total expenses before any offset, the amount of offset and the net expenses. 7. Capital Share Transactions Transactions in Capital Shares of the Fund were as follows: YEAR ENDED YEAR ENDED JUNE 30, 2007 JUNE 30, 2006 ------------------------------- ------------------------------- SHARES AMOUNT SHARES AMOUNT ---------- ------------ ---------- ------------ CLASS A SHARES: Proceeds from shares sold .............. 643,809 $ 6,762,397 1,156,856 $ 12,253,231 Reinvested distributions ............... 203,145 2,134,004 204,800 2,162,577 Cost of shares redeemed ................

TRUSTEES' FEES AND EXPENSES At June 30, 2007 there were 7 Trustees, one of which is affiliated with the Manager and is not paid any fees. The total amount of Trustees' service and attendance fees paid during the year ended June 30, 2007 was $109,500, to cover carrying out their responsibilities and attendance at regularly scheduled quarterly Board Meetings and meetings of the Independent Trustees held prior to each quarterly Board Meeting. When additional or special meetings are held, the meeting fees are paid to those Trustees in attendance. Trustees are reimbursed for their expenses such as travel, accommodations, and meals incurred in connection with attendance at Board Meetings and at the Annual Meeting of Shareholders. For the year ended June 30, 2007, such meeting-related expenses amounted to $37,128. 9. INCOME TAX INFORMATION AND DISTRIBUTIONS The Fund declares dividends daily from net investment income and makes payments monthly in additional shares at the net asset value per share, in cash, or in a combination of both, at the shareholder's option. Net realized capital gains, if any, are distributed annually and are taxable. The Fund intends to maintain, to the maximum extent possible, the tax-exempt status of interest payments received from portfolio municipal securities in order to allow dividends paid to shareholders from net investment income to be exempt from regular Federal and State of Rhode Island income taxes. However, due to differences between financial statement reporting and Federal income tax reporting requirements, distributions made by the Fund may not be the same as the Fund's net investment income, and/or net realized securities gains. In this regard, the Fund credited undistributed net investment income in the amount of $278,524 and debited additional paid-in capital in the amount of $278,524 at June 30, 2007. This adjustment had no impact on the Fund's aggregate net assests at June 30, 2007. Further, a small portion of the dividends may, under some circumstances, be subject to taxes at ordinary income rates. At June 30, 2007, the Fund had a capital loss carryover of $879,705 of which $592,992 expires on June 30, 2009, $111,495 expires on June 30, 2013, and $175,218 expires on June 30, 2015. This carryover is available to offset future net realized gains on securities transactions to the extent provided for in the Internal Revenue Code. To the extent that this loss is used to offset future realized capital gains, it is probable the gains so offset will not be distributed. As of June 30, 2007 there were post-October capital loss deferrals of $27,660 which will be recognized in the following year. Tax character of distributions: YEAR ENDED JUNE 30, ---------------------------- 2007 2006 ----------- ----------- Net tax-exempt income $ 5,334,313 $ 5,431,934 Ordinary income 278,524 175,957 ----------- ----------- $ 5,612,837 $ 5,607,891 =========== =========== As of June 30, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed tax-exempt income $ 148,931 Accumulated net realized loss (879,705) Unrealized appreciation 1,468,208 Post-October capital loss deferrals (27,660) Other temporary differences (148,931) ----------- $ 560,843 =========== At June 30, 2007, the difference between book basis and tax basis unrealized appreciation was attributable primarily to the treatment of accretion of discounts and amortization of premiums. 10. RECENT DEVELOPMENTS In late May, 2007, the U. S. Supreme Court agreed to hear an appeal in DEPARTMENT OF REVENUE OF KENTUCKY V. DAVIS, a case concerning the constitutionality of differential tax treatment for interest from in-state vs. out-of-state municipal securities, a practice which is common among the majority of the states. If the U.S. Supreme Court affirms the prior decision, Kentucky (and all other states that differentially tax interest on municipal bonds) may then be required to accord equal income tax treatment to all municipal bond interest. While it is impossible to predict the consequences of such an outcome, they may include effects on the net asset values of the shares, and/or on the tax treatment of the dividends, of some or all single-state municipal bond funds, including the Fund. The case is expected to be heard and decided during the U.S. Supreme Court's October 2007 - April 2008 term, with a decision likely to be handed down in 2008.

The table below is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The table below is based on an investment of $1,000 invested on January 1, 2007 and held for the six months ended June 30, 2007. ACTUAL EXPENSES This table provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled "Expenses Paid During the Period". SIX MONTHS ENDED JUNE 30, 2007 ACTUAL TOTAL RETURN BEGINNING ENDING EXPENSES WITHOUT ACCOUNT ACCOUNT PAID DURING SALES CHARGES(1) VALUE VALUE THE PERIOD(2) - -------------------------------------------------------------------------------- Class A 0.15% $1,000.00 $1,001.50 $3.23 - -------------------------------------------------------------------------------- Class C (0.18)% $1,000.00 $ 998.20 $7.43 - -------------------------------------------------------------------------------- Class I 0.18% $1,000.00 $1,001.80 $3.82 - -------------------------------------------------------------------------------- Class Y 0.22% $1,000.00 $1,002.20 $2.48 - -------------------------------------------------------------------------------- (1) ASSUMES REINVESTMENT OF ALL DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS, IF ANY, AT NET ASSET VALUE AND DOES NOT REFLECT THE DEDUCTION OF THE APPLICABLE SALES CHARGES WITH RESPECT TO CLASS A SHARES OR THE APPLICABLE CONTINGENT DEFERRED SALES CHARGES ("CDSC") WITH RESPECT TO CLASS C SHARES. TOTAL RETURN IS NOT ANNUALIZED, AS IT MAY NOT BE REPRESENTATIVE OF THE TOTAL RETURN FOR THE YEAR. (2) EXPENSES ARE EQUAL TO THE ANNUALIZED EXPENSE RATIO OF 0.65%, 1.50%, 0.77% AND 0.50% FOR THE FUND'S CLASS A, C, I AND Y SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 181/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- ANALYSIS OF EXPENSES (UNAUDITED) (CONTINUED) HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table below provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other mutual funds. To do so, compare this 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of other mutual funds. Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs with respect to Class A shares. The example does not reflect the deduction of contingent deferred sales charges ("CDSC") with respect to Class C shares. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different mutual funds. In addition, if these transaction costs were included, your costs would have been higher. SIX MONTHS ENDED JUNE 30, 2007 HYPOTHETICAL ANNUALIZED BEGINNING ENDING EXPENSES TOTAL ACCOUNT ACCOUNT PAID DURING RETURN VALUE VALUE THE PERIOD(1) - -------------------------------------------------------------------------------- Class A 5.00% $1,000.00 $1,021.57 $3.26 - -------------------------------------------------------------------------------- Class C 5.00% $1,000.00 $1,017.36 $7.50 - -------------------------------------------------------------------------------- Class I 5.00% $1,000.00 $1,020.98 $3.86 - -------------------------------------------------------------------------------- Class Y 5.00% $1,000.00 $1,022.32 $2.51 - -------------------------------------------------------------------------------- (1) EXPENSES ARE EQUAL TO THE ANNUALIZED EXPENSE RATIO OF 0.65%, 1.50%, 0.77% AND 0.50% FOR THE TRUST'S CLASS A, C, I AND Y SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 181/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- INFORMATION AVAILABLE (UNAUDITED) Much of the information that the funds in the Aquila Group of Funds(SM) produce is automatically sent to you and all other shareholders.

ITEM 2. CODE OF ETHICS. (a) As of June 30, 2007 (the end of the reporting period) the Trust has adopted a code of ethics that applies to the Trust's principal executive officer(s)and principal financial officer(s) and persons performing similar functions ("Covered Officers") as defined in the Aquila Group of Funds Code of Ethics for Principal Executive and Senior Financial Officers under Section 406 of the Sarbanes-Oxley Act of 2002; (f)(1) Pursuant to Item 10(a)(1), a copy of the Trust's Code of Ethics that applies to the Trust's principal executive officer(s) and principal financial officer(s) and persons performing similar functions is included as an exhibit to its annual report on this Form N-CSR; (f)(2) The text of the Trust's Code of Ethics that applies to the Trust's principal executive officer(s) and principal financial officer(s) and persons performing similar functions has been posted on its Internet website which can be found at the Trust's Internet address at aquilafunds.com. ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT. (a)(1)(ii) The Board of Trustees of the Fund has determined that it does not have at least one audit committee financial expert serving on its audit committee. The Fund does not have such a person serving on the audit committee because none of the persons currently serving as Trustees happens to have the technical accounting and auditing expertise included in the definition of "audit committee financial expert" recently adopted by the Securities and Exchange Commission in connection with this Form N-CSR, and the Board has not heretofore deemed it necessary to seek such a person for election to the Board. The primary mission of the Board, which is that of oversight over the operations and affairs of the Fund, confronts the Trustees with a wide and expanding range of issues and responsibilities. The Trustees believe that, accordingly, it is essential that the Board's membership consist of persons with as extensive experience as possible in fulfilling the duties and responsibilities of mutual fund directors and audit committee members and, ideally, with extensive experience and background relating to the economic and financial sectors and securities in which the Fund invests, including exposure to the financial and accounting matters commonly encountered with respect to those sectors and securities. The Board believes that its current membership satisfies those criteria. It recognizes that it would also be helpful to have a member with the relatively focused accounting and auditing expertise reflected in the applicable definition of "audit committee financial expert," just as additional members with similarly focused technical expertise in other areas relevant to the Fund's operations and affairs would also contribute added value. However, the Board believes that the Fund is better served, and its assets better employed, by a policy of hiring experts in various the specialized area of technical accounting and auditing matters, if and as the Board identifies the need, rather than by seeking to expand its numbers by adding technical experts in the areas constituting its domain of responsibility. The Fund's Audit Committee Charter explicitly authorizes the Committee to retain such experts as it deems necessary in fulfilling its duties under the Charter. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. a) Audit Fees - The aggregate fees billed for professional services rendered by the principal accountant for the audit of the Registrant's annual financial statements were $16,000 in 2006 and $16,000 in 2007. b) Audit Related Fees - There were no amounts billed for audit-related fees over the past two years. c) Tax Fees - The Registrant was billed by the principal accountant $3,000 and $3,000 in 2006 and 2007, respectively, for return preparation and tax compliance. d) All Other Fees - There were no additional fees paid for audit and non-audit services other than those disclosed in a) thorough c) above. e)(1) Currently, the audit committee of the Registrant pre-approves audit services and fees on an engagement-by-engagement basis e)(2) None of the services described in b) through d) above were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X, all were pre-approved on an engagement-by-engagement basis. f) No applicable. g) There were no non-audit services fees billed by the Registrant's accountant to the Registrant's investment adviser or distributor over the past two years h) Not applicable.

A copy of the qualifications and procedures that must be met or followed by shareholders to properly submit a nominee candidate to the Committee may be obtained by submitting a request in writing to the Secretary of the Registrant. ITEM 11. CONTROLS AND PROCEDURES. (a) Based on their evaluation of the registrant's disclosure controls and procedures (as defined in Rule 30a-2(c) under the Investment Company Act of 1940) as of a date within 90 days of the filing of this report, the registrant's chief financial and executive officers have concluded that the disclosure controls and procedures of the registrant are appropriately designed to ensure that information required to be disclosed in the registrant's reports that are filed under the Securities Exchange Act of 1934 are accumulated and communicated to registrant's management, including its principal executive officer(s) and principal financial officer(s), to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the Securities and Exchange Commission.
