PORTFOLIO September 13, 2005 MANAGEMENT REVIEW FUND MANAGERS Joseph R. Baxter Co-Manager Robert F. Collins Co-Manager Andrew M. McCullagh, Jr. Co-Manager PLEASE DESCRIBE THE OVERALL MARKET CONDITIONS DURING THE FISCAL YEAR. The last three years have been remarkably similar; at least as it pertains to market expectations and how the actual markets can prove them wrong. In the beginning of calendar years 2003, 2004, and 2005, many market participants appeared convinced that interest rates were unreasonably low, and many managers adjusted the risk profiles of their portfolios to reflect the coming of higher rates and lower bond prices. In each year, the markets weathered the storms and generated positive results, with price gains adding to the income generated. Defensive strategies did not pan out. Over the 12 months ended August 31, 2005, the fixed income markets rallied while the Federal Reserve was in the midst of tightening credit by raising short-term rates -- notably, the fed-funds rate. The tightening cycle started at the end of June 2004, prior to the start of the fiscal year, and continues today. As of August 31, 2005, the Federal Reserve raised rates by one quarter of a percentage point at every one of its meetings -- a total of eight rate hikes that took the fed-funds rate from 1.50% to 3.50%. While the Federal Reserve's actions sent short-term yields in both the taxable and the tax-exempt bond markets higher, the reaction of the intermediate and long-term markets prompted Fed Chairman Alan Greenspan's "conundrum" comment earlier this year. This type of sustained market rally through a Fed tightening is highly unusual and is precisely what confounded many investors. In the municipal market, yields on two-year, AAA-rated bonds increased by 1.2% during the year, from 1.7%, to end the fiscal year near 2.9%. The crossover point where rates were relatively flat year-over-year was in the 10-year maturity range, where rates began and ended the year at about 3.5%. Longer rates fell. For example, yields dropped by four tenths of a percent on 30-year AAA-rated municipals, ending the fiscal year with yields of approximately 4.3% (source: Municipal Market Data). These divergent moves between short-term and long-term rates continued to "flatten the yield curve." In the Treasury market, the difference between the 2- and 30-year yields narrowed dramatically, from about two-and-a-half percentage points to less than half of a percent at the end of the fiscal year. Some market strategists have started discussing the prospects for, and implications of, an inverted yield curve. Historically, an inverted yield curve has been associated with the onset of an economic recession. The curve in the tax-exempt markets flattened as well, but not quite as dramatically. While the difference between 2- and 30-year high-grade municipal bond yields started the year at 2.9%, it narrowed by 1.5 percent, ending the year with a 1.4% differential. Historically, when the Treasury market has inverted, the municipal market has maintained a positively sloped curve. Municipal bonds, particularly long-term bonds, traded weaker relative to Treasuries during the year. Yields on 30-year AAA-rated municipals, measured as a percentage of the yield on long Treasury bonds, started the fiscal year at about 95%. By the end of June 2005, the ratio had increased above 100%. This would be typical -- the market was rallying and the Treasury market led the way toward lower yields. The municipal market recaptured some of that underperformance in the last two months, ending the year with yields at about 98% of the long Treasury bond. WHAT WAS THE INVESTMENT ENVIRONMENT LIKE DURING THE LAST 12 MONTHS IN ARIZONA, CALIFORNIA, AND COLORADO? Credit has performed very well this year, partially due to investors' desire to seek higher yields, but also due to the fact that quality continued to improve throughout the municipal market. A strong economic backdrop has largely been the cause. After several years of slow growth or even flat performance, Arizona's economy provided solid growth for the last two years. The state has produced the second fastest rate of job growth for 2005 to date, compared to all the states (Source: The Business Journal Phoenix). These solid growth trends provided the state with better-than-anticipated revenue flows. State revenues for the first eight months of fiscal 2005 increased by nearly 17%. However, expenditure pressures will continue to come from education, healthcare, and social services, limiting the state's financial flexibility. In order to maintain a lid on taxes while addressing these expenditure pressures, the governor has proposed various non-recurring revenue sources to balance the 2006 budget. 1 California had a similar pattern over the last two years, helping the state cope with its structural deficit problems. State revenues were up approximately 17% for the first eight months of fiscal 2005 (source: Municipal Market Data); with personal and corporate tax receipts coming in ahead of budget. The absence of any planned issuance of recovery bonds in the fiscal 2006 budget is credited to the strong revenue flow. Despite the increase in tax receipts, the California Department of Finance estimated that the budget gap will continue into next fiscal year. This ongoing fiscal challenge is a major reason for the still-low bond rating relative to other states (A2/A). After experiencing a sharper economic downturn than the nation in recent years, we believe Colorado is now recovering at a healthy pace. The state's employment declines bottomed out in early 2004. With the resumption of moderate growth in tax revenues, state finances appear to have improved over the past year and are expected to remain relatively stable in fiscal 2006. Voter initiatives limit state revenue and expenditure growth to the rate of population growth plus inflation. Any tax revenues that exceed the constitutional limit must be refunded. In November, voters will consider amendments to these initiatives. Without these amendments, the governor's office projects that the state will accrue a refund liability in fiscal 2006, with refund amounts growing significantly in subsequent years. Overall, municipal bond issuance has remained robust in 2005, and the western states are no exception. Total national issuance in 2005 may even surpass the record of $384 billion sold in 2003 if this pace remains. The drivers of this record volume continue to be the low interest rate environment and the flattening yield curve, both of which stimulate refunding activity. Arizona and Colorado have experienced 12% and 7% growth in new issue volume year-to-date, respectively. California new issuance levels are down by $5.5 billion, but recall that last year the state issued over $10 billion in recovery bonds. Excluding that issue, the state's new issue volume would have increased by 13% (source: Municipal Market Data). Much of the increase in each state reflects refunding activity (up 62% on a national basis). HOW DID DELAWARE TAX-FREE ARIZONA INSURED FUND PERFORM DURING THE FISCAL YEAR? For the fiscal year ended August 31, 2005, Delaware Tax-Free Arizona Insured Fund returned 5.74% (Class A shares at net asset value with distributions reinvested) and 0.96% (at maximum offer price with distributions reinvested).* Class A shares (at net asset value with distributions reinvested) outperformed the Lipper Arizona Municipal Debt Funds Universe Average, which returned 4.25%, and the Lehman Brothers Municipal Bond Index, which returned 5.31% for the 12-month period, both of which exclude sales charges (source: Lipper, Inc.).** *For complete annualized performance, see tables on pages 4, 6 and 8. **A portion of the income from tax-exempt funds may be subject to the alternative minimum tax. FOR EACH FUND, WHAT STRATEGIES INFLUENCED PERFORMANCE? Returns in each of the Funds were aided by yield-curve positioning, credit tightening, sector concentration, and security selection. While the Federal Reserve raised short-term rates by increasing the fed-funds target rate, long-term bond yields declined, as inflation remained tame during a period of moderate growth. This resulted in what is termed a "flattening of the yield curve," where the difference between long- and short-term rates narrows. The Funds are positioned to take advantage of this environment, combining long maturity bonds that participate in the rally and shorter-duration securities with high coupons trading to short calls that are less price sensitive. This is known as a "barbell" structure, and it generally aided in the returns for all three Funds. When the yield curve flattens and long-term interest rates decline, market participants seek alternative sources of yield. This is often found in lower-rated bonds, and as the market reaches for this yield, it causes the credit curve to tighten and results in good performance for those securities. Bonds rated A and BBB, and non-investment grade securities have all outperformed high-grade and insured bonds in the municipal market over the past year. The Funds benefited from allotment to these higher-risk credits. 2 Two of our favored sectors, healthcare and higher education, have benefited from both the market's reach for yield as well as positive fundamentals. The credit and financial environments have been positive for hospitals, as they have received favorable reimbursements from Medicare and the managed care industry. The demographics provided by the baby boom generation have provided favorable enrollment environment for colleges and universities while a recovering stock market has bolstered endowments. Individual security selection remains the heart of our investment process and is the primary source of our excess returns. Some securities that have performed well over the past year in Delaware Tax-Free Arizona Insured Fund include a Maricopa healthcare issue for Catholic Healthcare West and an Arizona State University bond. There was a refinancing of a Southern Arizona Capital Facilities bond, issued for the University of Arizona, which resulted in a significant upward price move during the fiscal year. In addition, two issues for U.S. territories, one for Puerto Rico and one for the Virgin Islands, performed well due to their longer maturities. In Delaware Tax-Free California Fund, we are favorable on the tobacco bonds enhanced by a state appropriation, and our Golden State Tobacco positions that are backed by the State of California were among the Fund's best performing securities. The bonds were pre-refunded to their first call date and appreciated in price. Like Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund owned a healthcare bond secured by Catholic Healthcare West, which was a top performer for the year. Rounding out some of the other top performers in California were two long maturity general obligation bonds (California and San Diego Unified School District), a higher education revenue bond that was refinanced (Pepperdine University), and a seasoned land development issue (Southern California Logistics Airport Project). Delaware Tax-Free Colorado Fund also had healthcare and education bonds contribute to performance, as well as several refinancing events. Bonds issued for Evangelical Lutheran and Vail Valley Medical Center were top healthcare performers, and a bond issued for the Montessori Charter schools topped the list for education bonds. There were several bonds refunded during the year, which often generates a price pop due to the improved security standing of the issue. DETRACTED FROM FUND PERFORMANCE? Detracting from each of our Funds' performance, relative to its benchmark index, was the significant decision to avoid the unenhanced tobacco sector. This sector, in which we did not participate, has been the best performing sector in the municipal bond market over the past year and the biggest influence on market performance. The master settlement agreement between the major tobacco companies and 46 states secures these bonds. However, the sector is subject to litigation risk and, therefore, volatile. We are comfortable foregoing this potential volatility in the Funds. Airline securities significantly outperformed the municipal market this year during the second and third quarters, which are a traditional busy season. Although the Funds held several airport revenue bonds, we have been underweighted in this sector and have generally avoided securities backed by airline corporation revenues, as we are concerned about the long-term fundamentals of the industry. The decision to hold high-coupon, short-call legacy bonds provides an above market yield to the portfolios and helps to balance the Funds' interest rate exposure, offsetting the bonds with long maturities. However, during the fiscal year it resulted in negligible price performance during market rallies due to the short duration of the securities. This decision to hold these underperforming securities also detracted from relative performance. 3 PERFORMANCE SUMMARY DELAWARE TAX-FREE ARIZONA INSURED FUND The performance data quoted represent past performance; past performance does not guarantee future results.

Performance for Class B and C shares, excluding sales charges, assumes either that contingent deferred sales charges did not apply or the investment was not redeemed. The Fund offers Class A, B, and C shares. Class A shares are sold with a front-end sales charge of up to 4.50% and have an annual distribution and service fee of up to 0.25%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. They are also subject to an annual distribution and service fee of 1%. Lifetime and 10-year performance figures for Class B shares reflect conversion to Class A shares after eight years. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. They are also subject to an annual distribution and service fee of 1%. An expense limitation was in effect for all classes of Delaware Tax-Free Arizona Insured Fund during the periods shown. Performance would have been lower had the expense limitation not been in effect. The performance table does not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares.

The Lehman Brothers Municipal Bond Index is an unmanaged index that generally tracks the performance of municipal bonds. An index is unmanaged and does not reflect the costs of operating a mutual fund, such as the costs of buying, selling, and holding securities. You cannot invest directly in an index. The performance graph does not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemption of Fund shares. An expense limitation was in effect for all classes of the Delaware Tax-Free Arizona Insured Fund during the period shown.

Past performance is not a guarantee of future results. 5 DISCLOSURE For the period March 1, 2005 to August 31, 2005 OF FUND EXPENSES As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. The following examples are intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005 to August 31, 2005. ACTUAL EXPENSES The first section of the tables shown, "Actual Fund Return," provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second section of the tables shown, "Hypothetical 5% Return," provides information about hypothetical account values and hypothetical expenses based on the Funds' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds' actual returns. 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 this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Each Fund's actual expenses shown in each table reflect fee waivers in effect. The expenses shown in each table assume reinvestment of all dividends and distributions. "Expenses Paid During Period" are equal to the Funds' annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

This change in accounting had no impact for the year ended August 31, 2002. Per share data and ratios for periods prior to September 1, 2001 have not been restated to reflect this change in accounting.

Voyageur Insured Funds (the "Trust") is organized as a Delaware statutory trust and offers two series: Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free Minnesota Insured Fund. Voyageur Mutual Funds II (the "Trust") is organized as a Delaware statutory trust and offers one series: Delaware Tax-Free Colorado Fund. These financial statements and related notes pertain to Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund (each a "Fund" and, collectively, the "Funds"). The above Trusts are open-end investment companies. The Funds are considered non-diversified under the Investment Company Act of 1940, as amended. The Funds offer Class A, Class B, and Class C shares. Class A shares are sold with a front-end sales charge of up to 4.50%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. The investment objective of Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund is to seek as high a level of current income exempt from federal income tax and personal income tax in their respective states, as is consistent with preservation of capital. 1. SIGNIFICANT ACCOUNTING POLICIES The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Funds. Security Valuation -- Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Open-end investment companies are valued at their published net asset value. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of each Fund's Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes -- Each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting -- Investment income and common expenses are allocated to the classes of each Fund on the basis of "settled shares" of each class in relation to the net assets of each Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of each Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Use of Estimates -- The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other -- Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date). Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. Each Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. The Funds receive earnings credits from their custodian when positive balances are maintained, which are used to offset custody fees. The expense paid under the above arrangement is included in custodian fees on the Statements of Operations with the corresponding expense offset shown as "expense paid indirectly". The amount of this expense for the year ended August 31, 2005 was as follows: Delaware Tax-Free Arizona Insured Fund -------------------- Earnings credits $713 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES In accordance with the terms of its respective investment management agreement, each Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee based on each Fund's average daily net assets as follows: Delaware Tax-Free Arizona Insured Fund -------------------- On the first $500 million 0.500% On the next $500 million 0.475% On the next $1.5 billion 0.450% In excess of $2.5 billion 0.425% 16 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES (CONTINUED) DMC has contractually agreed to waive that portion, if any, of its management fee and reimburse each Fund to the extent necessary to ensure that annual operating expenses, exclusive of taxes, interest, brokerage commissions, distribution fees, certain insurance costs and extraordinary expenses, do not exceed specified percentages of average daily net assets as shown below: Delaware Tax-Free Arizona Insured Fund -------------------- Operating expense limitation as a percentage of average daily net assets (per annum) 0.70% Expiration Date 10/31/04 Effective November 1, 2004, operating expense limitation as a percentage of average daily net assets (per annum) 0.53% Expiration Date 3/31/06 Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective May 19, 2005, each Fund pays DSC a monthly fee computed at the annual rate of 0.04% of each Fund's average daily net assets for accounting and administration services. Prior to May 19, 2005, each Fund paid DSC a monthly fee based on average net assets subject to certain minimums for accounting and administration services. Each Fund pays DSC a monthly fee based on the number of shareholder accounts for dividend disbursing and transfer agent services. Pursuant to a distribution agreement and distribution plan, each Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.25% of the average daily net assets of the Class A shares and 1.00% of the average daily net assets of the Class B and C shares. At August 31, 2005, each Fund had liabilities payable to affiliates as follows: Delaware Tax-Free Arizona Insured Fund -------------------- Investment management fees payable to DMC $34,422 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 13,254 Other expenses payable to DMC and affiliates* 70,008 *DMC, as a part of its administrative services, pays operating expenses on behalf of each Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. As provided in the investment management agreement, each Fund bears the cost of certain legal services expenses, including internal legal services provided to each Fund by DMC employees. For the year ended August 31, 2005, Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund were charged $1,618, $1,683, and $7,141, respectively, for internal legal services provided by DMC.

DIVIDEND AND DISTRIBUTION INFORMATION Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended August 31, 2005 and 2004 was as follows: Delaware Tax-Free Arizona Insured Fund -------------------------- Year Ended 2005 2004 Tax-exempt income $5,887,149 $6,003,395 Ordinary income -- 203,220 Long-term capital gain 261,925 582,564 ---------- ---------- Total $6,149,074 $6,789,179 ========== ========== As of August 31, 2005, the components of net assets on a tax basis were as follows: Delaware Tax-Free Arizona Insured Fund -------------------- Shares of beneficial interest $154,759,933 Undistributed tax-exempt income -- Other temporary differences (20,294) Post-October losses -- Capital loss carryforwards (2,789,466)* Unrealized appreciation of investments 10,520,319 ------------ Net assets $162,470,492 ============ *The amount of this loss which can be utilized in subsequent years is subject to an annual limitation in accordance with the Internal Revenue Code due to the fund merger with Delaware Tax-Free Arizona Fund (see Note 6).

DIVIDEND AND DISTRIBUTION INFORMATION (CONTINUED) For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount and premium on certain debt instruments. Results of operations and net assets were not affected by these reclassifications. For the year ended August 31, 2005, the Funds recorded the following reclassifications. Delaware Tax-Free Arizona Insured Fund -------------------- Undistributed (distributions in excess of) net investment income $(27,608) Accumulated net realized gain 27,608 5.

FUND REORGANIZATION Effective April 11, 2005, Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free California Fund acquired all of the assets and assumed all of the liabilities of Delaware Tax-Free Arizona Fund and Delaware Tax-Free California Insured Fund, respectively, each an open-end investment company, pursuant to Plans and Agreements of Reorganization (the "Reorganizations"). The shareholders of Delaware Tax-Free Arizona Fund and Delaware Tax-Free California Insured Fund received shares of the respective class of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free California Fund, respectively, equal to the aggregate net asset value of their shares prior to the Reorganizations based on the net asset value per share of the respective classes of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free California Fund. The Reorganizations were treated as non-taxable events and, accordingly, each of Delaware Tax-Free Arizona Insured Fund's and Delaware Tax-Free California Fund's basis in the securities acquired reflected the historical cost basis as of the date of transfer. The net assets, net unrealized appreciation and accumulated net realized gain (loss) of Delaware Tax-Free Arizona Fund and Delaware Tax-Free California Insured Fund as of the close of business on April 8, 2005, were as follows: Net Unrealized Accumulated Net Net Assets Appreciation Realized Gain/Loss ----------- -------------- ------------------ Delaware Tax-Free Arizona Fund $28,887,777 $1,078,069 $(3,053,750)* *Includes prior year capital loss carryforwards The net assets of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free California Fund prior to the Reorganizations were $134,516,468 and $46,891,287, respectively. The combined net assets of Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free California Fund after the Reorganization were $163,404,245 and $78,384,033, respectively. 7. LINE OF CREDIT Each Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $183,100,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Funds had no amounts outstanding as of August 31, 2005, or at any time during the fiscal year. 8. CREDIT AND MARKET RISK The Funds concentrate their investments in securities issued by municipalities. The value of these investments may be adversely affected by new legislation within the states, regional or local economic conditions, and differing levels of supply and demand for municipal bonds. Many municipalities insure repayment for their obligations. Although bond insurance reduces the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. These securities have been identified in the Statements of Net Assets. Each Fund may invest in advanced refunded bonds, escrow secured bonds or defeased bonds. Under current federal tax laws and regulations, state and local government borrowers are permitted to refinance outstanding bonds by issuing new bonds. The issuer refinances the outstanding debt to either reduce interest costs or to remove or alter restrictive covenants imposed by the bonds being refinanced. A refunding transaction where the municipal securities are being refunded within 90 days or less from the issuance of the refunding issue is known as a "current refunding". "Advance refunded bonds" are bonds in which the refunded bond issue remains outstanding for more than 90 days following the issuance of the refunding issue. In an advance refunding, the issuer will use the proceeds of a new bond issue to purchase high grade interest bearing debt securities which are then deposited in an irrevocable escrow account held by an escrow agent to secure all future payments of principal and interest and bond premium of the advance refunded bond. Bonds are "escrowed to maturity" when the proceeds of the refunding issue are deposited in an escrow account for investment sufficient to pay all of the principal and interest on the original interest payment and maturity dates. Bonds are considered "pre-refunded" when the refunding issue's proceeds are escrowed only until a permitted call date or dates on the refunded issue with the refunded issue being redeemed at the time, including any required premium. Bonds become " when the rights and interests of the bondholders and of their lien on the pledged revenues or other security under the terms of the bond contract are substituted with an alternative source of revenues (the escrow securities) sufficient to meet payments of principal and interest to maturity or to the first call dates. Escrowed secured bonds will often receive a rating of AAA from Moody's, S&P, and/or Fitch due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement. The Tax-Free Insured Funds will purchase escrow secured bonds without additional insurance only where the escrow is invested in securities of the U.S. government or agencies or instrumentalities of the U.S. government. Each Fund may invest up to 15% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. At August 31, 2005, there were no Rule 144A securities and no securities have been determined to be illiquid under the Fund's Liquidity Procedures. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Funds' limitation on investments in illiquid assets. 20 NOTES TO FINANCIAL STATEMENTS (CONTINUED) 9. CONTRACTUAL OBLIGATIONS The Funds enter into contracts in the normal course of business that contain a variety of indemnifications. The Funds' maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these contracts. Management has reviewed each Fund's existing contracts and expects the risk of loss to be remote. 10. TAX INFORMATION (UNAUDITED) The information set forth below is for each Fund's fiscal year as required by federal laws. Shareholders, however, must report distributions on a calendar year basis for income tax purposes, which may include distributions for portions of two fiscal years of a Fund. Accordingly, the information needed by shareholders for income tax purposes will be sent to them in January of each year. Please consult your tax advisor for proper treatment of this information. For the fiscal year ended August 31, 2005, each Fund designates distributions paid during the year as follows: (A) (B) Long Term Tax- Capital Gains Exempt Total Distributions Distributions Distributions (Tax Basis) (Tax Basis) (Tax Basis) ------------- ------------- -------------- Delaware Tax-Free Arizona Insured Fund 4% 96% 100% (A) and (B) are based on a percentage of each Fund's total distributions. 21 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees Voyageur Insured Funds - Delaware Tax-Free Arizona Insured Fund Voyageur Mutual Funds -Delaware Tax-Free California Fund Voyageur Mutual Funds II - Delaware Tax-Free Colorado Fund We have audited the accompanying statements of net assets of Delaware Tax-Free Arizona Insured Fund (one of the series constituting Voyageur Insured Funds), Delaware Tax-Free California Fund (one of the series constituting Voyageur Mutual Funds), and Voyageur Mutual Funds II (comprised of Delaware Tax-Free Colorado Fund) (the "Funds") as of August 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. 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. We were not engaged to perform an audit of the Funds' 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 Funds' 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 and financial highlights, assessing the accounting principles used and significant estimates made by management, evaluating the overall financial statement presentation. Our audit procedures included confirmation of securities owned as of August 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 the Delaware Tax-Free Arizona Insured Fund of Voyageur Insured Funds, the Delaware Tax-Free California Fund of Voyageur Mutual Funds, and the Delaware Tax-Free Colorado Fund of Voyageur Mutual Funds II at August 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Philadelphia, Pennsylvania October 14, 2005 22 OTHER FUND INFORMATION PROXY RESULTS The shareholders of Voyageur Mutual Funds, Voyageur Insured Funds, Voyageur Investment Trust and Voyageur Mutual Funds II (each a "Trust") voted on the following proposals (as applicable) at the special meeting of shareholders on March 23, 2005 or as adjourned.

For Against Abstain Broker Non-Votes ---- -------- -------- ----------------- Delaware Tax-Free Arizona Insured Fund 6,190,221 309,263 454,358 964,429 23 OTHER FUND INFORMATION (CONTINUED) BOARD CONSIDERATION OF DELAWARE TAX-FREE ARIZONA INSURED FUND, DELAWARE TAX-FREE CALIFORNIA FUND AND DELAWARE TAX-FREE COLORADO FUND INVESTMENT ADVISORY AGREEMENT At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Boards of Trustees, including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory Agreements for the Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund (each a "Fund" and together the "Funds"). In making its decision, the Board considered information furnished throughout the year at regular Board meetings, as well as information prepared specifically in connection with the Annual Meeting. Information furnished and discussed throughout the year included reports detailing Fund performance, investment strategies, expenses, compliance matters and other services provided by Delaware Management Company ("DMC"), the investment advisor. Information furnished specifically in connection with the Annual Meeting included materials provided by DMC and its affiliates ("Delaware Investments") concerning, among other things, the level of services provided to the Funds, the costs of such services to the Funds, economies of scale and the financial condition and profitability of Delaware Investments. In addition, in connection with the Annual Meeting, the Board separately received and reviewed independent historical and comparative reports prepared by Lipper Inc. ("Lipper"), an independent statistical compilation organization. The Lipper reports compared each Fund's investment performance and expenses with those of other comparable mutual funds. The Board also requested and received certain supplemental information regarding management's policy with respect to advisory fee levels and its philosophy with respect to breakpoints; the structure of portfolio manager compensation; the investment manager's profitability organized by client type, including the Funds; and any constraints or limitations on the availability of securities in certain investment styles which might inhibit the advisor's ability to fully invest in accordance with each Fund's policies. In considering such materials, the independent Trustees received assistance and advice from and met separately with independent counsel and representatives from Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman of the Delaware Investments(R) Family of Funds, and Chairman and Chief Executive Officer of the investment advisor, was present to respond to questions raised by Lipper and the independent Trustees. While the Board considered the Investment Advisory Agreements for all of the funds in the Delaware Investments Family of Funds at the same Board meeting, information was provided and considered by the Board for each fund individually. In approving the continuance of the Investment Advisory Agreements for the Funds, the Board, including a majority of independent Trustees, determined that the existing advisory fee structure was fair and reasonable and that the continuance of the Investment Advisory Agreements was in the best interests of the Funds and their shareholders. While attention was given to all information furnished, the following discusses the primary factors relevant to the Board's deliberations and determination, including those relating to the selection of the investment advisor and the approval of the advisory fee. NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services provided by Delaware Investments to the Funds and their shareholders. In reviewing the nature, extent and quality of services, the Board emphasized reports furnished to it throughout the year at regular Board meetings covering matters such as the compliance of portfolio managers with the investment policies, strategies and restrictions for the Funds, the compliance of management personnel with the Code of Ethics adopted throughout the Delaware Investments(R) Family of Funds complex, the adherence to fair value pricing procedures as established by the Board, and the accuracy of net asset value calculations. The Board noted that it was pleased with the current staffing of the Funds' investment advisor during the past year, the emphasis on research and the compensation system for advisory personnel. Favorable consideration was given to DMC's efforts to maintain, and in some instances increase, financial and human resources committed to fund matters. Other factors taken into account by the Board were Delaware Investments' preparedness for, and response to, legal and regulatory matters. The Board also considered the transfer agent and shareholder services provided to Fund shareholders by Delaware Investments' affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate of the DALBAR Pyramid Award in four of the last six years and the continuing expenditures by Delaware Investments to increase and improve the scope of shareholder services. Additionally, the Board noted the extent of benefits provided to Fund shareholders for being part of the Delaware Investments Family of Funds, including the privilege to exchange investments between the same class of funds without a sales charge, the ability to reinvest Fund dividends into other funds and the privilege to combine holdings in other funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent and quality of the overall services provided by Delaware Investments. INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC and the Funds. The Board was pleased by DMC's investment performance, noting Barron's ranking of the Delaware Investments Family of Funds in the top quartile of mutual fund families for 2002 - 2004. The Board placed significant emphasis on the investment performance of the Funds in view of its importance to shareholders. While consideration was given to performance reports and discussions with portfolio managers at Board meetings throughout the year, particular attention in assessing performance was given to the Lipper reports furnished for the Annual Meeting. The Lipper reports prepared for each Fund showed the investment performance of its Class A shares in comparison to a group of similar funds as selected by Lipper (the "Performance Universe"). A fund with the highest performance is ranked first, and a fund with the lowest is ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25% -- the second quartile; the next 25% -- the third quartile; and the lowest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for the Funds was shown for the past one-, three-, five- and 10-year periods, as applicable, ended February 28, 2005. The Board noted its objective that each Fund's performance be at or above the median of its Performance Universe. The following paragraphs summarize the performance results for the Funds and the Board's view of such performance. DELAWARE TAX-FREE ARIZONA INSURED FUND -- The Performance Universe for this Fund consisted of the Fund and all retail and institutional Arizona municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund's total return for the one-, five- and 10-year periods was in the first quartile of such Performance Universe. The report further showed that the Fund's total return for the three year period was in the second quartile. The Board was satisfied with such performance. 24 OTHER FUND INFORMATION (CONTINUED) COMPARATIVE EXPENSES. The Board considered expense comparison data for the Delaware Investments(R) Family of Funds, Delaware Investments' institutional separate account business and other lines of business at Delaware Investments. The Board stated its belief that, given the differing level of service provided to Delaware Investments' various clients and other factors that related to the establishment of fee levels, variations in the levels of fees and expenses were justified. The Board placed significant emphasis on the comparative analysis of the management fees and total expense ratios of each Fund compared with those of a group of similar funds as selected by Lipper (the "Expense Group") and among the other Delaware Investments funds. In reviewing comparative costs, each Fund's contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees (as reported by each fund) of other funds within the Expense Group, taking into effect any applicable breakpoints and fee waivers. Each Fund's total expenses were also compared with those of its Expense Group. The Lipper total expenses, for comparative consistency, were shown by Lipper for Class A shares and compared total expenses including 12b-1 and non-12b-1 service fees. The Board noted its objective to limit each Fund's total expense ratio to an acceptable range as compared to the median of the Expense Group. The following paragraphs summarize the expense results for the Funds and the Board's view of such expenses. DELAWARE TAX-FREE ARIZONA INSURED FUND -- The expense comparisons for the Fund showed that its management fee was in the quartile with the second highest expenses of its Expense Group and its total expenses were in the quartile with the highest expenses of its Expense Group. The Board noted that the Fund's total expenses were not in line with the Board's objective. In evaluating the total expenses, the Board considered waivers in place through March 2006. The Board was satisfied with management's efforts to improve the Fund's total expense ratio and bring it in line with the Board's objective. DELAWARE TAX-FREE CALIFORNIA FUND -- The expense comparisons for the Fund showed that its management fee and total expenses were in the quartile with the lowest expenses of its Expense Group. The Board was satisfied with the management fees and total expenses of the Fund in comparison to its Expense Group as shown in the Lipper report. DELAWARE TAX-FREE COLORADO FUND -- The expense comparisons for the Fund showed that its management fee and total expenses were in the quartile with the highest expenses of its Expense Group. The Board noted that the Fund's total expenses were not in line with the Board's objective. In evaluating the total expenses, the Board considered waivers in place through October 2005. The Board was satisfied with management's efforts to improve the Fund's total expense ratio and bring it in line with the Board's objective. MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any, realized by Delaware Investments in connection with the operation of the Funds. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of Delaware Investments' business in providing management and other services to each of the individual funds and the Delaware Investments Family of Funds as a whole. Specific attention was given to the methodology followed in allocating costs for the purpose of determining profitability. Management stated that the level of profits of Delaware Investments, to a certain extent, reflected operational cost savings and efficiencies initiated by Delaware Investments. The Board considered Delaware Investments' expenditures to improve services provided to fund shareholders and to meet additional regulatory and compliance requirements resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also considered the extent to which Delaware Investments might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as service provider to the Delaware Investments Family of Funds, the benefits from allocation of fund brokerage to improve trading efficiencies and the use of "soft" commission dollars to pay for proprietary and non-proprietary research. At the Board's request, management also provided information relating to Delaware Investments' profitability by client type. The information provided set forth the revenue, expenses and pre-tax income/loss attributable to the Delaware Investments Family of Funds, Delaware Investments' separate account business and other lines of business at Delaware Investments. Emphasis was given to the level and type of service provided to the various clients. The Board was satisfied with the level of profits realized by Delaware Investments from its relationships with the Funds and the Delaware Investments Family of Funds. ECONOMIES OF SCALE. The Trustees considered whether economies of scale are realized by Delaware Investments as each Fund's assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees took into account the standardized advisory fee pricing and structure approved by the Board and shareholders as part of a complex-wide shareholder meeting conducted in 1998/1999. At that time, Delaware Investments introduced breakpoints to account for management economies of scale. The Board noted that the fee under each Fund's management contract fell within the standard structure. Although the Funds have not reached a size at which they can take advantage of breakpoints, the Board recognized that the fee was structured so that when the Funds grow, economies of scale may be shared. 25 DELAWARE INVESTMENTS(R) FAMILY OF FUNDS BOARD OF TRUSTEES/DIRECTORS AND OFFICERS ADDENDUM A mutual fund is governed by a Board of Trustees/Directors ("Trustees"), which has oversight responsibility for the management of a fund's business affairs.

PORTFOLIO DELAWARE MINNESOTA MUNICIPAL BOND FUNDS MANAGEMENT REVIEW August 31, 2005 FUND MANAGERS Joseph R. Baxter, Co-manager Robert F. Collins, Co-manager Patrick P. Coyne, Co-manager PLEASE DESCRIBE THE OVERALL MARKET CONDITIONS DURING THE FISCAL YEAR. The last three years have been remarkably similar; at least as it pertains to market expectations and how the actual markets can prove them wrong. In the beginning of calendar years 2003, 2004, and 2005, market participants were convinced that interest rates were unreasonably low, and many managers adjusted the risk profiles of their portfolios to reflect the coming of higher rates and lower bond prices. In each year, the markets weathered the storms and generated positive results, with price gains adding to the income generated. Defensive strategies did not pan out. Over the last 12 months ended August 31, 2005, the fixed income markets rallied while the Federal Reserve was in the midst of tightening credit by raising short-term rates - notably, the fed funds rate. The tightening cycle started at the end of June 2004, prior to the start of the fiscal year, and continues today. As of August 31, 2005, the Federal Reserve raised rates by one quarter of a percentage point at every one of its meetings - a total of eight rate hikes that took the fed funds rate from 1.50% to 3.50%. While the Federal Reserve's actions sent short-term yields in both the taxable and the tax-exempt bond markets higher, the reaction of the intermediate and long-term markets prompted Fed Chairman Alan Greenspan's "conundrum" comment earlier this year. This type of sustained market rally through a Fed tightening is highly unusual and is precisely what confounded many investors. In the municipal market, yields on two-year, AAA-rated bonds increased by 1.2% during the year, from 1.7% to end the fiscal year near 2.9%. The crossover point where rates were relatively flat year-over-year was in the 10-year maturity range, where rates began and ended the year at about 3.5%. Longer rates fell. For example, yields dropped by four tenths of a percent on 30-year AAA-rated municipals, ending the fiscal year with yields of approximately 4.3%. (source: Municipal Market Data) These divergent moves between short-term and long-term rates continued to flatten the yield curve. Historically, an inverted yield curve has been associated with the onset of an economic recession. The curve in the tax-exempt markets flattened as well, but not quite as dramatically. While the difference between 2- and 30-year high-grade municipal bonds started the year at 2.9%, it narrowed by 1.5%, ending the year with a 1.4% differential (Source: Municipal Market Data). Historically, when the Treasury market has inverted, the municipal market has maintained a positively sloped curve. Municipal bonds, particularly long-term bonds, traded weaker relative to Treasuries during the year. Yields on 30-year AAA-rated municipals, measured as a percentage of the yield on long Treasury bonds, started the fiscal year at about 95%. By the end of June 2005, the ratio had increased above 100%. This would be typical - the market was rallying and the Treasury market led the way toward lower yields. The municipal market recaptured some of that underperformance in the last two months, ending the year with yields at about 98% of the long Treasury bond. In our opinion, credit has performed very well this year, partially due to investors' desire to seek higher yields, but also due to the fact that quality continued to improve throughout the municipal market. A strong economic backdrop has largely been the cause. Revenue recovery has firmly taken hold and is easing the transition to structural budget balance for most states. Driving the revenue gains, total non-farm payrolls increased 1.7% in the 12-months ending August 2005, while the unemployment rate decreased from 5.5% to 5.0%(source: US Department of Labor). As a result, most states are experiencing better-than-budgeted growth to date for fiscal 2005, which is providing additional resources to balance fiscal 2006 and lending support for growing spending demands. For the first eight months of fiscal 2005, state revenues were up a total of 9.5%, with personal income tax and sales tax increases leading the way. Additional factors contributing to positive revenue trends were conservative budget forecasting, low interest rates and the strong real estate market (source: Municipal Market Data). Spending pressures still loom, threatening budget stability. The federal government will likely be a source of budget strain in the coming years as it grapples with its own budget deficit. States may also have to deal with traditional budget issues such as social service programs and education funding. The future in most states will depend on economic performance, sustained structural balance, and progress in re-building financial/budget reserves. Municipal bond issuance remained robust in 2005. As of August 31, 2005, issuance totaled $275.49 billion, a 13.10% increase over the same period last year. Total issuance in 2005 may even surpass the record of $384 billion sold in 2003 if this 1 pace continues. Drivers of this record volume continue to be the low interest rate environment and the flattening yield curve, both of which stimulate refunding activity. Year-to-date, refunding activity was up 62.1% from the same period a year ago. At the same time, low rates are attractive for new money sales, which increased 12.8% (source: Municipal Market Data). The healthcare sector has seen significant increase in new-money issuance due to the sector's improved credit conditions and need to invest in facilities. Other sectors that registered significant jumps in issuance included transportation and general purpose bonds. WHAT WAS THE ECONOMIC AND MUNICIPAL MARKET ENVIRONMENT IN MINNESOTA DURING THE LAST 12 MONTHS? Minnesota enjoys a deep and diverse economy, supported by several regional economic centers and anchored by the Minneapolis-St. Paul MSA. However, Minnesota's manufacturing concentration and the state's reliance on the income tax revenue generated by those jobs combined to hit the state hard during and after the manufacturing-led 2001 recession. Employment increased 1.5% in the past twelve months through August 2005. The recovery is broad, with gains in services, construction and manufacturing. Minnesota's unemployment rate has also improved to 3.6% as of August 2005 (source: Municipal Market Data). In fiscal 2004, revenues came in above estimates. The additional revenues were primarily in personal income tax, a sharp departure from the last several years when actual receipts from the personal income tax continually came in below forecast. According to the state, economically sensitive revenues continue to perform close to forecast, with better-than-expected growth in corporate profits offsetting slightly below average growth in more consumer-based revenues such as sales. During the first nine months of fiscal 2005, total revenues grew almost 6% (source: Municipal Market Data). For the first eight months of 2005, new issuance in Minnesota was up 25.3% over the same period a year ago. As of August 31, 2005, Minnesota issued $4.9 billion of debt compared to $3.9 billion a year ago. One of the larger issuances was from Minneapolis & St. Paul Minnesota Metropolitan Airports (source: The Bond Buyer). HOW DID DELAWARE TAX-FREE MINNESOTA INSURED FUND PERFORM DURING THE FISCAL YEAR? For the fiscal year ended August 31, 2005, Delaware Tax-Free Minnesota Insured Fund returned 5.42% (Class A shares at net asset value with distributions reinvested) and 0.67% (at maximum offer price with distributions reinvested). Class A shares (at net asset value with distributions reinvested) outperformed both the Lipper Minnesota Municipal Debt Funds Average, which returned 4.33%, and the Lehman Brothers Municipal Bond Index, which returned 5.31% for the 12-month period. (source: Lipper, Inc.).* 2 FOR EACH FUND, WHAT STRATEGIES CONTRIBUTED TO FUND PERFORMANCE? The Funds' returns were generally aided by yield curve positioning, credit spread tightening, sector concentration, and security selection. The relative contribution of these first three components varies based on the individual Fund's mandate asset forth in its prospectus. The fourth factor, security selection, is the heart of our investment process and is the primary source of our returns. While the Federal Reserve raised short-term rates, long-term bond yields declined as inflation remained tame during a period of moderate growth. This resulted in what is termed as a "flattening of the yield curve," where the difference between long- and short-term rates narrows. The Funds are positioned to take advantage of this environment, combining long maturity bonds and shorter duration securities with high coupons trading to short calls that are less price sensitive. This is known as a "barbell" portfolio structure, and it generally aided our performance. When the yield curve flattens and long-term interest rates decline, market participants seek alternative sources of yield. This is often found in lower-rated bonds, and as the market reaches for this yield it causes the credit curve to tighten and results in good performance for those securities. Securities rated A, BBB and non-investment grade have all outperformed high-grade and insured bonds in the municipal market over the past year. The Funds benefited from a meaningful allotment to these credits. Two of our favored sectors, healthcare and higher education, benefited from both the market's reach for yield as well as positive fundamentals. The credit and financial environments have been positive for hospitals, as they have received favorable reimbursements from Medicare. The demographics provided by the baby boom generation have provided favorable enrollment trends at colleges and universities, while recovering stock market has bolstered endowments. Despite a structural deficit, various bonds issued by the Commonwealth of Puerto Rico also performed well during the period. The Delaware Tax-Free Minnesota Fund has the broadest mandate of the four Minnesota funds and has therefore been able to participate in all four sources of return. The Fund's portfolio is structured as a "barbell"; it has a meaningful allotment in mid-to-lower investment grade credits and therefore participated in some of the better performing sectors, but it also received a significant contribution from the high-quality, pre-refunded sector. That contribution came primarily from the refinancing (pre-refunding) of a large position of Fairview Hospital in Minneapolis and provided an above market price appreciation on that bond. This leaves the Fund with a security escrowed in U.S. government securities and an above market coupon that we will collect for years to come. Delaware Tax-Free Minnesota Insured Fund was well positioned for a flattening of the yield curve with a significant allocation of bonds having maturities 15 years and longer. Legacy bonds that have short due dates or short calls complete the barbell. The Fund's insured mandate limits it from participating fully in the credit spread tightening of lower rated bonds and the associated sectors of the market. The Fund is allowed to own up to 20% of its securities in non-insured bonds and we maximized our use of non-insureds during the period to gain excess returns. Delaware Tax-Free Minnesota Intermediate Fund was also well positioned to benefit from a flatter yield curve, but due to its intermediate mandate, the long end of the barbell is structured in the 10- to 20-year part of the curve. The Fund has also benefited from an allocation to Single A and Triple BBB rated securities and some of their associated sectors. Excess returns were found in the Healthcare sector in Park Nicollet and Allina Health Systems. While Delaware Minnesota High-Yield Municipal Bond Fund's structure is that of a barbell, the securities in it are less sensitive to interest rate movements and more dependent on credit quality. This fund not only has a healthy allotment in A and BBB bonds, but also in non-investment grade securities. It owns both BB-rated bonds and comparable quality non-rated securities. These rating classes and their corresponding sectors have generally led the way in the municipal market over the last year. CAN YOU NAME SOME KEY HOLDINGS IN THE FUNDS? In the Delaware Tax-Free Minnesota Fund, other hospital positions that have performed well in terms of total return are Benedictine Health Systems in Duluth, Park Nicollet Health Systems in St. Louis Park and St. Francis Regional Medical Center in Shakopee. Also aiding in performance were multifamily housing projects in Minneapolis, St. Cloud, Stillwater, and Hutchinson. In the Delaware Tax-Free Minnesota Insured Fund, securities in this category were some of the same healthcare systems previously mentioned such as Benedictine and Park Nicollet, but Allina Health System in Minneapolis also joined them. Also in the Fund were bonds for an International Paper plant located 3 in Sartell. There were plenty of AAA securities including the insured Minneapolis Airport bonds, insured Southern Minnesota Municipal Power Agency bonds, and the escrowed Dakota & Washington Counties single family housing bonds. The Fund also owned large positions in Fairview Hospital that were pre-refunded during the period and appreciated in price. In the Delaware Tax-Free Minnesota Intermediate Fund, securities for the Healtheast Hospital Project in St. Paul also provided additional return when Moody's upgraded the bonds to investment grade. Other significant contributors to performance in this fund were various higher education bonds such as the Walker Art Center in Minneapolis and the Minnesota College of Art & Design, along with securities for the State University Foundation Project in St. Cloud. The top two performers were a multifamily housing project in Minneapolis for the Trinity Apartments and the aforementioned Fairview Hospital bonds that were refinanced. In the Delaware Tax-Free Minnesota High-Yield Municipal Bond Fund, excess returns have come from a variety of securities for hospitals, multifamily housing projects, corporate backed debt, higher education institutions and senior living facilities. The senior living bonds can be for either one or some combination of independent living, assisted living and skilled nursing facilities. Holdings included, a nursing home known as the Forest Health Services Project, the Jones-Harrison Residence in Minneapolis and in Twin Valley, the Living Options community. Other individual securities included the previously mentioned hospitals or health systems such as Benedictine, Allina, Park Nicollet, St. Francis Medical Center and the pre-refunded Fairview Hospital bonds. We also held bonds financing various multifamily housing projects such as Trinity Apartments and Grant Street Apartments in Minneapolis, along with the Evergreen Apartments in Hutchinson. Corporate backed debt has contributed through securities such as industrial development bonds for International Paper and special facility bonds for Northwest Airlines. WHAT DETRACTED FROM FUND PERFORMANCE? Detracting from our Funds' performance relative to the benchmark index was the decision to avoid the unenhanced tobacco sector. This sector, which we did not participate in, has been the best performing sector in the municipal bond market over the past year and the biggest influence on market performance. The master settlement agreement between the major tobacco companies and 46 states secures unenhanced tobacco bonds. The sector is subject to litigation risk, and thus may add volatility. We are comfortable foregoing a potential source of volatility in the Funds. Airline securities significantly outperformed the municipal market this year during the second and third quarter, which is a traditional busy season. Although the Funds held several airport revenue bonds, we have been under weight in this sector and we have generally avoided securities backed by airport corporation revenues. We are concerned about the long-term fundamentals of the industry. The decision to hold high coupon, short-call bonds provides an above market yield to the portfolios and helps to balance the Funds' interest rate exposure, offsetting the bonds with long maturities. However, during the fiscal year it resulted in negligible price performance during market rallies due to the short duration of the securities. The decision to hold these underperfoming bonds resulted in weakened performance, relative to the benchmark and our peers. GLOSSARY AVERAGE MATURITY: For a bond fund, this is the weighted average of the stated maturity dates of the portfolio's securities. In general, the longer the average maturity, the greater the fund's sensitivity to interest rate changes, which can mean greater price fluctuation. A shorter average maturity usually means less interest rate sensitivity and, consequently, a less volatile portfolio. BASIS POINT: One one-hundredth of one percentage point, or 0.01%. DURATION: A measure of a bond or bond fund's sensitivity to changes in interest rates. All else being equal, a fund with a duration of four years would fall about 4% in response to a one-percentage-point rise in rates, and vice versa. SPREAD: the difference between any two prices or yields. YIELD CURVE: A curve that shows the relationship between yields and maturity dates for a set of similar bonds, usually Treasuries, at a given point in time. 4 This page intentionally left blank. 5 PERFORMANCE SUMMARY DELAWARE TAX-FREE MINNESOTA INSURED FUND The performance data quoted represent past performance; past performance does not guarantee future results.

Performance for Class B and C shares, excluding sales charges, assumes either contingent deferred sales charges did not apply or the investment was not redeemed. The Fund offers Class A, B, and C shares. Class A shares are sold with a front-end sales charge of up to 4.50% and have an annual distribution and service fee of up to 0.25%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. They are also subject to an annual distribution and service fee of 1%. Lifetime and 10-year performance figures for Class B shares reflect conversion to Class A shares after eight years. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the periods shown. They are also subject to an annual distribution and service fee of 1%. An expense limitation was in effect for all classes of Delaware Tax-Free Minnesota Insured Fund during the periods shown. Performance would have been lower had the expense limitation not been in effect. The performance table does not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares. A portion of the income from tax-exempt funds may be subject to the alternative minimum tax. 6 FUND BASICS As of August 31, 2005 - -------------------------------------------------------------------------------- FUND OBJECTIVE: The Fund seeks as high a level of current income exempt from federal income tax and from the Minnesota state personal income tax, as is consistent with preservation of capital. - -------------------------------------------------------------------------------- TOTAL FUND NET ASSETS: $251 million - -------------------------------------------------------------------------------- NUMBER OF HOLDINGS: 81 - -------------------------------------------------------------------------------- FUND START DATE: May 1, 1987 - -------------------------------------------------------------------------------- YOUR FUND MANAGERS: Joseph R.

The Lehman Brothers Municipal Bond Index is an unmanaged index that generally tracks the performance of municipal bonds. An index is unmanaged and does not reflect the costs of operating a mutual fund, such as the costs of buying, selling, and holding securities. You cannot invest directly in an index. The performance graph does not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares. An expense limitation was in effect for all classes of Delaware Tax-Free Minnesota Insured Fund during the periods shown.

Past performance is not a guarantee of future results. 7 DISCLOSURE For the Period March 1, 2005 to August 31, 2005 OF FUND EXPENSES As a shareholder of a Fund, you may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. The following examples are intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005 to August 31, 2005. ACTUAL EXPENSES The first section of the tables shown, "Actual Fund Return," provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second section of the tables shown, "Hypothetical 5% Return," provides information about hypothetical account values and hypothetical expenses based on the Funds' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds' actual returns. 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 this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Each Fund's actual expenses shown in each table reflect fee waivers in effect. The expenses shown in each table assume reinvestment of all dividends and distributions. "Expenses Paid During Period" are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

Voyageur Insured Funds (the "Trust") is organized as a Delaware statutory trust and offers two series: Delaware Tax-Free Arizona Insured Fund and Delaware Tax-Free Minnesota Insured Fund. Voyageur Tax Free Funds (the "Trust") is organized as a Delaware business trust and offers the Delaware Tax-Free Minnesota Fund. Voyageur Intermediate Tax Free Funds (the "Trust") is organized as a Delaware statutory trust and offers the Delaware Tax-Free Minnesota Intermediate Fund. These financial statements and related notes pertain to Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund, Delaware Tax-Free Minnesota Intermediate Fund and Delaware Minnesota High-Yield Municipal Bond Fund (each referred to as a "Fund" or, collectively, the "Funds"). The above Trusts are open-end investment companies. The Funds are considered non-diversified under the Investment Company Act of 1940, as amended, and offer Class A, Class B, and Class C shares. Class A shares are sold with a front-end sales charge of up to 4.50% for Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund and Delaware Minnesota High-Yield Municipal Bond Fund and up to 2.75% for Delaware Tax-Free Minnesota Intermediate Fund. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero for Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund and Delaware Minnesota High-Yield Municipal Bond Fund and that declines from 2% to zero for Delaware Tax-Free Minnesota Intermediate Fund, depending upon the period of time the shares are held.

Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. The investment objective of Delaware Tax-Free Minnesota Fund and Delaware Tax-Free Minnesota Insured Fund is to seek as high a level of current income exempt from federal income tax and from the Minnesota state personal income tax, as is consistent with preservation of capital. The investment objective of Delaware Tax-Free Minnesota Intermediate Fund is to seek to provide investors with preservation of capital and, secondarily, current income exempt from federal income tax and from the Minnesota state personal income tax, by maintaining a dollar-weighted average effective portfolio maturity of 10 years or less. The investment objective of Delaware Minnesota High-Yield Municipal Bond Fund is to seek as high a level of current income exempt from federal income tax and from the Minnesota state personal income tax, primarily through investment in medium- and lower-grade municipal obligations. 1. SIGNIFICANT ACCOUNTING POLICIES The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Funds. Security Valuation -- Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of each Fund's Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes -- Each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting -- Investment income and common expenses are allocated to the classes of each Fund on the basis of "settled shares" of each class in relation to the net asset of each Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of each Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Use of Estimates -- The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and each reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other -- Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date). Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. Each Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. The Funds receive earnings credits from their custodian when positive cash balances are maintained, which are used to offset custody fees. The expense paid under the above arrangement is included in custodian fees on the Statements of Operations with the corresponding expenses offset shown as "expense paid indirectly". The amount of this expense for the year ended August 31, 2005 was as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- Earnings credits $1,212 18 NOTES DELAWARE MINNESOTA MUNICIPAL BOND FUNDS TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES In accordance with the terms of its respective investment management agreement, each Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee based on each Fund's average daily net assets as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- On the first $500 million 0.500% On the next $500 million 0.475% On the next $1.5 billion 0.450% In excess of $2.5 billion 0.425% DMC has contractually agreed to waive that portion, if any, of its management fee and reimburse each Fund to the extent necessary to ensure that annual operating expenses, exclusive of taxes, interest, brokerage commissions, distribution fees, certain insurance costs and extraordinary expenses, do not exceed specified percentages of average daily net assets as shown below: Delaware Tax-Free Minnesota Insured Fund ----------------- Operating expense limitation as a percentage of average daily net assets (per annum) 0.75% Expiration date 10/31/04 Effective November 1, 2004, Operating expense limitation as a percentage of average daily net assets (per annum) 0.64% Expiration date 10/31/06 Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective May 19, 2005, each Fund pays DSC a monthly fee computed at the annual rate of 0.04% of each Fund's average daily net assets for accounting and administration services. Prior to May 19, 2005, each Fund paid DSC a monthly fee based on average net assets subject to certain minimums for accounting and administration services. Each Fund pays DSC a monthly fee based on the number of shareholder accounts for dividend disbursing and transfer agent services. Pursuant to a distribution agreement and distribution plan, each Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.25% of the average daily net assets of the Class A shares and 1.00% of the average daily net assets of the Class B and C shares. DDLP has contracted to waive distribution fees through October 31, 2005 in order to prevent distribution fees of Class A from exceeding 0.15% of average daily net assets for Delaware Tax-Free Minnesota Intermediate Fund. At August 31, 2005, each Fund had liabilities payable to affiliates as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- Investment management fee payable to DMC $109,904 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 21,340 Other expenses payable to DMC and affiliates* 84,735 *DMC, as part of its administrative services, pays operating expenses on behalf of each Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. 19 NOTES DELAWARE MINNESOTA MUNICIPAL BOND FUNDS TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES (CONTINUED) As provided in the investment management agreement, each Fund bears the cost of certain legal services expenses, including internal legal services provided to each Fund by DMC employees. For the year ended August 31, 2005, each Fund was charged for internal legal services provided by DMC as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- $13,461 For the year ended August 31, 2005, DDLP earned commissions on sales of Class A shares for each Fund as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- $43,079 For the year ended August 31, 2005, DDLP received gross contingent deferred sales charge commissions on redemption of each Fund's Class A, Class B and Class C shares, respectively. These commissions were entirely used to offset up-front commissions previously paid by DDLP to broker-dealers on sales of those shares. The amounts received were as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- Class A $ -- Class B 22,085 Class C 3,222 Certain officers of DMC, DSC, and DDLP are officers and/or trustees of the Trusts. These officers and trustees are paid no compensation by the Funds. 3. INVESTMENTS For the year ended August 31, 2005, the Funds made purchases and sales of investment securities other than short-term investments as follows: Delaware Tax-Free Minnesota Insured Fund ---------------- Purchases $23,334,273 Sales 32,601,320 At August 31, 2005, the cost of investments and unrealized appreciation (depreciation) for federal income tax purposes for each Fund were as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- Cost of investments $228,920,094 ============ Aggregate unrealized appreciation $ 19,741,989 Aggregate unrealized depreciation (4,933) ------------ Net unrealized appreciation $ 19,737,056 ============ 20 NOTES DELAWARE MINNESOTA MUNICIPAL BOND FUNDS TO FINANCIAL STATEMENTS (CONTINUED) 4. DIVIDEND AND DISTRIBUTION INFORMATION Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended August 31, 2005 and 2004 was as follows: Delaware Tax-Free Minnesota Insured Fund ---------------- Year ended 8/31/05 ----------------------- Tax-exempt income $9,960,686 Long-term capital gain 1,119,256 ----------- Total $11,079,942 =========== Year ended 8/31/04 ----------------------- Tax-exempt income $11,175,457 Ordinary income -- Long-term capital gain -- ----------- Total $11,175,457 =========== As of August 31, 2005, the components of net assets on a tax basis were as follows: Delaware Tax-Free Minnesota Insured Fund ----------------- Shares of beneficial interest $231,063,341 Undistributed tax-exempt income -- Undistributed long-term capital gain 476,138 Capital loss carryforwards -- Unrealized appreciation of investments 19,737,056 ------------ Net assets $251,276,535 ============ The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales and tax treatment of market discount on debt instruments. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount on certain debt instruments. Results of operations and net assets were not affected by these reclassifications. For the year ended August 31, 2005, the Funds recorded the following reclassifications: Delaware Tax-Free Minnesota Insured Fund ----------------- Undistributed net investment income (loss) ($45,603) Accumulated realized gain (loss) 45,603 21 NOTES DELAWARE MINNESOTA MUNICIPAL BOND FUNDS TO FINANCIAL STATEMENTS (CONTINUED) 5.

LINE OF CREDIT Each Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $183,100,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Funds had no amounts outstanding as of August 31, 2005 or at any time during the year. 7. CREDIT AND MARKET RISK The Funds concentrate their investments in securities issued by municipalities, mainly in Minnesota. The value of these investments may be adversely affected by new legislation within the state, regional or local economic conditions, and differing levels of supply and demand for municipal bonds. Many municipalities insure repayment for their obligations. Although bond insurance reduces the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. These securities have been identified in the Statements of Net Assets. Each Fund may invest in inverse floating rate securities ("inverse floaters"), a type of derivative tax-exempt obligation with floating or variable interest rates that move in the opposite direction of short-term interest rates, usually at an accelerated speed. Consequently, the market values of inverse floaters will generally be more volatile than other tax-exempt investments. Such securities are denoted on the Statement of Net Assets. The Fund's may invest in advanced refunded bonds, escrow secured bonds or defeased bonds. Under current federal tax laws and regulations, state and local government borrowers are permitted to refinance outstanding bonds by issuing new bonds. The issuer refinances the outstanding debt to either reduce interest costs or to remove or alter restrictive covenants imposed by the bonds being refinanced. A refunding transaction where the municipal securities are being refunded within 90 days or less from the issuance of the refunding issue is known as a "current refunding". "Advance refunded bonds" are bonds in which the refunded bond issue remains outstanding for more than 90 days following the issuance of the refunding issue. In an advance refunding, the issuer will use the proceeds of a new bond issue to purchase high grade interest bearing debt securities which are then deposited in an irrevocable escrow account held by an escrow agent to secure all future payments of principal and interest and bond premium of the advance refunded bond. Bonds are "escrowed to maturity" when the proceeds of the refunding issue are deposited in an escrow account for investment sufficient to pay all of the principal and interest on the original interest payment and maturity dates. Bonds are considered "pre-refunded" when the refunding issue's proceeds are escrowed only until a permitted call date or dates on the refunded issue with the refunded issue being redeemed at the time, including any required premium. Bonds become "defeased" when the rights and interests of the bondholders and of their lien on the pledged revenues or other security under the terms of the bond contract are substituted with an alternative source of revenues (the escrow securities) sufficient to meet payments of principal and interest to maturity or to the first call dates. Escrowed secured bonds will often receive a rating of AAA from Moody's, S&P, and/or Fitch due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement. The Tax-Free Minnesota Insured Fund will purchase escrow secured bonds without additional insurance only where the escrow is invested in securities of the U.S. government or agencies or instrumentalities of the U.S. government. Each Fund may invest a portion of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. At August 31, 2005, there were no Rule 144A securities and no securities have been determined to be illiquid under the Fund's Liquidity Procedures. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Funds' limitation on investments in illiquid assets. 8. CONTRACTUAL OBLIGATIONS The Funds enter into contracts in the normal course of business that contain a variety of indemnifications. The Funds' maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these contracts. Management has reviewed each Fund's existing contracts and expects the risk of loss to be remote. 9. TAX INFORMATION (UNAUDITED) The information set forth below is for each Fund's fiscal year as required by federal laws. Shareholders, however, must report distributions on a calendar year basis for income tax purposes, which may include distributions for portions of two fiscal years of a Fund. Accordingly, the information needed by shareholders for income tax purposes will be sent to them in January of each year. Please consult your tax advisor for proper treatment of this information. For the fiscal year ended August 31, 2005, each Fund designates distributions paid during the year as follows: (A) (B) Long-Term Ordinary (C) (D) Capital Gains Income Tax Exempt Total Distributions Distributions Distributions Distributions (Tax Basis) (Tax Basis) (Tax Basis) (Tax Basis) -------------------------------------------------------------------------- Delaware Tax-Free Minnesota Insured Fund 10% -- 90% 100% (A), (B), and (C) are based on a percentage of each Fund's total distributions. 23 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees Voyageur Tax Free Funds - Delaware Tax-Free Minnesota Fund Voyageur Insured Funds - Delaware Tax-Free Minnesota Insured Fund Voyageur Intermediate Tax Free Funds - Delaware Tax-Free Minnesota Intermediate Fund Voyageur Mutual Funds - Delaware Minnesota High-Yield Municipal Bond Fund We have audited the accompanying statements of net assets of Voyageur Tax Free Funds (comprised of Delaware Tax-Free Minnesota Fund), Delaware Tax-Free Minnesota Insured Fund (one of the series constituting Voyageur Insured Funds), Voyageur Intermediate Tax Free Funds (comprised of Delaware Tax-Free Minnesota Intermediate Fund) and Delaware Minnesota High-Yield Municipal Bond Fund (one of the series constituting Voyageur Mutual Funds) (the "Funds") as of August 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. 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. We were not engaged to perform an audit of the Funds' 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 Funds' 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 and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit procedures included confirmation of securities owned as of August 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 the Delaware Tax-Free Minnesota Fund of Voyageur Tax Free Funds, the Delaware Tax-Free Minnesota Insured Fund of Voyageur Insured Funds, the Delaware Tax-Free Minnesota Intermediate Fund of Voyageur Intermediate Tax Free Funds, and the Delaware Minnesota High-Yield Municipal Bond Fund of Voyageur Mutual Funds at August 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

For Against Abstain --- ------- ------- Delaware Tax-Free Minnesota Insured Fund 2,436,002.703 779,176.132 763,621.190 BOARD CONSIDERATION OF DELAWARE MINNESOTA MUNICIPAL BOND FUNDS INVESTMENT ADVISORY AGREEMENT At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Boards of Trustees, including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory Agreements for the Delaware Minnesota High-Yield Municipal Bond Fund, Delaware Tax-Free Minnesota Fund, Delaware Tax-Free Minnesota Insured Fund and Delaware Tax-Free Minnesota Intermediate Fund (each a "Fund" and together the "Funds"). In making its decision, the Board considered information furnished throughout the year at regular Board meetings, as well as information prepared specifically in connection with the Annual Meeting. Information furnished and discussed throughout the year included reports detailing Fund performance, investment strategies, expenses, compliance matters and other services provided by Delaware Management Company ("DMC"), the investment advisor. Information furnished specifically in connection with the Annual Meeting included materials provided by DMC and its affiliates ("Delaware Investments") concerning, among other things, the level of services provided to the Funds, the costs of such services to the Funds, economies of scale and the financial condition and profitability of Delaware Investments. In addition, in connection with the Annual Meeting, the Board separately received and reviewed independent historical and comparative reports prepared by Lipper Inc. ("Lipper"), an independent 25 OTHER DELAWARE MINNESOTA MUNICIPAL BOND FUNDS FUND INFORMATION (CONTINUED) BOARD CONSIDERATION OF DELAWARE MINNESOTA MUNICIPAL BOND FUNDS INVESTMENT ADVISORY AGREEMENT (CONTINUED) statistical compilation organization. The Lipper reports compared each Fund's investment performance and expenses with those of other comparable mutual funds. The Board also requested and received certain supplemental information regarding management's policy with respect to advisory fee levels and its philosophy with respect to breakpoints; the structure of portfolio manager compensation; the investment manager's profitability organized by client type, including the Funds; and any constraints or limitations on the availability of securities in certain investment styles which might inhibit the advisor's ability to fully invest in accordance with each Fund's policies. In considering such materials, the independent Trustees received assistance and advice from and met separately with independent counsel and representatives from Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman of the Delaware Investments Family of Funds, and Chairman and Chief Executive Officer of the investment advisor, was present to respond to questions raised by Lipper and the independent Trustees. While the Board considered the Investment Advisory Agreements for all of the funds in the Delaware Investments Family of Funds at the same Board meeting, information was provided and considered by the Board for each fund individually. In approving the continuance of the Investment Advisory Agreements for the Funds, the Board, including a majority of independent Trustees, determined that the existing advisory fee structure was fair and reasonable and that the continuance of the Investment Advisory Agreements was in the best interests of the Funds and their shareholders. While attention was given to all information furnished, the following discusses the primary factors relevant to the Board's deliberations and determination, including those relating to the selection of the investment advisor and the approval of the advisory fee. NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services provided by Delaware Investments to the Funds and their shareholders. In reviewing the nature, extent and quality of services, the Board emphasized reports furnished to it throughout the year at regular Board meetings covering matters such as the compliance of portfolio managers with the investment policies, strategies and restrictions for the Funds, the compliance of management personnel with the Code of Ethics adopted throughout the Delaware Investments Family of Funds complex, the adherence to fair value pricing procedures as established by the Board, and the accuracy of net asset value calculations. The Board noted that it was pleased with the current staffing of the Funds' investment advisor during the past year, the emphasis on research and the compensation system for advisory personnel. Favorable consideration was given to DMC's efforts to maintain, and in some instances increase, financial and human resources committed to fund matters. Other factors taken into account by the Board were Delaware Investments' preparedness for, and response to, legal and regulatory matters. The Board also considered the transfer agent and shareholder services provided to Fund shareholders by Delaware Investments' affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate of the DALBAR Pyramid Award in four of the last six years and the continuing expenditures by Delaware Investments to increase and improve the scope of shareholder services. Additionally, the Board noted the extent of benefits provided to Fund shareholders for being part of the Delaware Investments Family of Funds, including the privilege to exchange investments between the same class of funds without a sales charge, the ability to reinvest Fund dividends into other funds and the privilege to combine holdings in other funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent and quality of the overall services provided by Delaware Investments. INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC and the Funds. The Board was pleased by DMC's investment performance, noting Barron's ranking of the Delaware Investments Family of Funds in the top quartile of mutual fund families for 2002 - 2004. The Board placed significant emphasis on the investment performance of the Funds in view of its importance to shareholders. While consideration was given to performance reports and discussions with portfolio managers at Board meetings throughout the year, particular attention in assessing performance was given to the Lipper reports furnished for the Annual Meeting. The Lipper reports prepared for each Fund showed the investment performance of its Class A shares in comparison to a group of similar funds as selected by Lipper (the "Performance Universe"). A fund with the highest performance is ranked first, and a fund with the lowest is ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25% - the second quartile; the next 25% - the third quartile; and the lowest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for the Funds was shown for the past one, three, five and 10 year periods, as applicable, ended February 28, 2005. The Board noted its objective that each Fund's performance be at or above the median of its Performance Universe. The following paragraphs summarize the performance results for the Funds and the Board's view of such performance. DELAWARE TAX-FREE MINNESOTA INSURED FUND -- The Performance Universe for this Fund consisted of the Fund and all retail and institutional Minnesota municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund's total return for the one, five and 10 year periods was in the second quartile of such Performance Universe. The report further showed that the Fund's total return for the three year period was in the first quartile. The Board was satisfied with such performance. 26 OTHER DELAWARE MINNESOTA MUNICIPAL BOND FUNDS FUND INFORMATION (CONTINUED) BOARD CONSIDERATION OF DELAWARE MINNESOTA MUNICIPAL BOND FUNDS INVESTMENT ADVISORY AGREEMENT (CONTINUED) COMPARATIVE EXPENSES. The Board considered expense comparison data for the Delaware Investments Family of Funds, Delaware Investments' institutional separate account business and other lines of business at Delaware Investments. The Board stated its belief that, given the differing level of service provided to Delaware Investments' various clients and other factors that related to the establishment of fee levels, variations in the levels of fees and expenses were justified. The Board placed significant emphasis on the comparative analysis of the management fees and total expense ratios of each Fund compared with those of a group of similar funds as selected by Lipper (the "Expense Group") and among the other Delaware Investments funds. In reviewing comparative costs, each Fund's contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees (as reported by each fund) of other funds within the Expense Group, taking into effect any applicable breakpoints and fee waivers. Each Fund's total expenses were also compared with those of its Expense Group. The Lipper total expenses, for comparative consistency, were shown by Lipper for Class A shares and compared total expenses including 12b-1 and non-12b-1 service fees. The Board noted its objective to limit each Fund's total expense ratio to an acceptable range as compared to the median of the Expense Group. The following paragraphs summarize the expense results for the Funds and the Board's view of such expenses. DELAWARE TAX-FREE MINNESOTA INSURED FUND -- The expense comparisons for the Fund showed that its management fee and total expenses were in the quartile with the second highest expenses of its Expense Group. The Board noted that the Fund's total expenses were not in line with the Board's objective. In evaluating the total expenses, the Board considered waivers in place through October 2005. The Board was satisfied with management's efforts to improve the Fund's total expense ratio and bring it in line with the Board's objective. MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any, realized by Delaware Investments in connection with the operation of the Funds. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of Delaware Investments' business in providing management and other services to each of the individual funds and the Delaware Investments Family of Funds as a whole. Specific attention was given to the methodology followed in allocating costs for the purpose of determining profitability. Management stated that the level of profits of Delaware Investments, to a certain extent, reflected operational cost savings and efficiencies initiated by Delaware Investments. The Board considered Delaware Investments' expenditures to improve services provided to fund shareholders and to meet additional regulatory and compliance requirements resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also considered the extent to which Delaware Investments might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as service provider to the Delaware Investments Family of Funds, the benefits from allocation of fund brokerage to improve trading efficiencies and the use of "soft" commission dollars to pay for proprietary and non-proprietary research. At the Board's request, management also provided information relating to Delaware Investments' profitability by client type. The information provided set forth the revenue, expenses and pre-tax income/loss attributable to the Delaware Investments Family of Funds, Delaware Investments' separate account business and other lines of business at Delaware Investments. Emphasis was given to the level and type of service provided to the various clients. The Board was satisfied with the level of profits realized by Delaware Investments from its relationships with the Funds and the Delaware Investments Family of Funds. ECONOMIES OF SCALE. The Trustees considered whether economies of scale are realized by Delaware Investments as each Fund's assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees took into account the standardized advisory fee pricing and structure approved by the Board and shareholders as part of a complex-wide shareholder meeting conducted in 1998/1999. At that time, Delaware Investments introduced breakpoints to account for management economies of scale. The Board noted that the fee under each Fund's management contract fell within the standard structure.
