Portfolio management review Delaware Investments Closed-End Municipal Bond Funds April 11, 2006 Fund managers Joseph Baxter Portfolio Manager Arizona Municipal Income Fund, Colorado Insured Municipal Income Fund, Florida Insured Municipal Income Fund, Minnesota Municipal Income Funds II Robert Collins Portfolio Manager Arizona Municipal Income Fund, Colorado Insured Municipal Income Fund, Florida Insured Municipal Income Fund, Minnesota Municipal Income Funds II Denise Franchetti Portfolio Manager Arizona Municipal Income Fund, Colorado Insured Municipal Income Fund, Florida Insured Municipal Income Fund, Minnesota Municipal Income Funds II Q: What was the investment environment like for municipal bond funds during the fiscal year ended March 31, 2006? A: Changes in interest rates and municipal bond refinancings were among the key stories in the municipal bond market during the fiscal year. The Federal Reserve Board remained committed to tightening U.S. monetary policy, focused on keeping inflation in check. This included a continuous string of eight quarter-point increases to the fed funds rate, which took this target for short-term interest rates from 2.75% on March 22, 2005 to 4.75% as of March 31, 2006 (source: The U.S. Federal Reserve Board). Despite the fed's actions on short-term interest rates, however, longer term rates did not increase and generally remained low throughout the course of the fiscal year. The 30-year AAA-rated municipal bond yield, for instance, actually declined over the course of the fiscal year, from 4.58% to 4.48% on March 31, 2006 (source: Municipal Market Data). Rising short-term rates, coupled with the long-term rate downward trend, created a situation that economists typically refer to as a "flattening yield curve," meaning that the difference between short- and long-term bond yields grows smaller across the spectrum of maturities. In this type of environment, bonds with intermediate maturities -- such as those in the three- to seven-year maturity range -- frequently underperform. We found this to be particularly true during the second half of the fiscal year, when the flattening of the yield curve became more pronounced. Credit quality among municipal bond issuers generally improved during the fiscal year, and it was another factor influencing the markets. A result of these improving credit qualities was an increase in demand for high yield -- or non-investment grade -- bonds, which performed well. Similarly, among investment grade municipal bonds, lower-rated securities often outperformed higher-rated securities by a significant margin on a total return basis. Q: What other market-related events influenced performance of municipal bond funds? A: Issuance of new municipal bonds remained strong during most of the fiscal year. Supply of new municipal bonds is typically assessed on a calendar year basis and, for example, supply in calendar year 2005 totaled a record $408 billion (source: Municipal Market Data). Driving the record issuance was low interest rates, which provided many issuers with refinancing opportunities. The market's ability to absorb additional supply was aided by non-traditional buyers (buyers more interested in the relative valuation of the asset class than the tax-advantaged status of municipal bonds). As more and more municipal issuers refinanced in 2005, new issuance dropped off. During the first months of 2006, the rate of new issuance had declined significantly. For much of the fiscal year, a preferred strategy in all of our municipal bond funds was to hold onto bonds purchased in prior fiscal periods, and to depend on the attractive bond yields that already exist within our Funds. Generally, with interest rates in decline, it became (continued) 1 Portfolio management review Delaware Investments Closed-End Municipal Bond Funds increasingly difficult to identify bonds in the marketplace that were more attractive than our holdings in the portfolio. We believed that selling older bonds that were purchased with attractive yields would only serve to "rotate down" the Funds' yields and potentially generate undesirable taxable gains. Across each of the closed-end municipal bond funds, we adhered to our bottom-up investment style, which is based on security-by-security analysis and a free exchange of information among the various members of a deep management team that includes portfolio managers, credit analysts, and traders. Frequently during the year, we opted to focus our resources on monitoring the credit of legacy bonds, which are bonds purchased in prior fiscal periods. Arizona Municipal Income Fund Q: What conditions prevailed in the Arizona debt market? A: Job growth in Arizona continued to accelerate in 2005 and ranked second nationwide. Employment grew approximately 5.3% in 2005, the most rapid rate of annual growth since 1998 (source: Bureau of Labor Statistics). Recent job growth was led by the construction sector, as well as the trade, transportation, and utilities sectors. As of February 2006, the state's unemployment rate was hovering at 4.4%, which was well below the national level of 4.8%. While personal income grew in 2005, it was hampered by job losses in the manufacturing and information sectors, two of the highest paid sectors in Arizona. As a result, Arizona personal income remains below national levels at approximately 87% of the U.S. average (source: Moody's Investors Service). In fiscal 2005, Arizona's tax revenues increased 19.4%, led by strong personal and corporate income taxes. Arizona's Budget Stabilization Fund totaled $147 million as of June 30, 2005. Arizona's fiscal year 2006 budget totals $8.2 billion and increases base spending by about 7%. The budget includes salary increases for state workers, tax revisions, and an establishment of a full-day kindergarten program (source: Nelson A. Rockefeller Institute of Government and the Fiscal Survey of States-National Governor's Association). Q: How did the Fund perform versus its benchmark and peer group? A: Arizona Municipal Income Fund returned 3.31%* (at net asset value with all distributions reinvested), underper-forming both the peer group and the benchmark. By comparison, the Lipper Other States Municipal Debt Funds gained an average of 5.08% for the same period. The Fund's benchmark -- the national Lehman Brothers Municipal Bond Index -- gained 3.81% (source: Lipper). Q: What strategies affected Fund performance? A: The Fund underperformed the benchmark due to a lack of exposure to industrial development revenue bonds and pollution control revenue bonds (IDC/PCR) over the 12-month period. The IDR/PCR sector includes tobacco bonds, which we have not invested in as an across-the-board policy in our municipal funds due to the volatility associated with the sub-sector. The IDR/PCR sector was by far the best performing segment in the Index, posting a +9.59% return for the period. When excluding tobacco bonds, the IDR/PCR sector returned only +3.82% over 12 months. The Fund was also negatively affected by a significant underweighting in BBB-rated bonds. By policy, there was no exposure to non-investment grade bonds. These two rating categories outperformed by a considerable margin, posting returns of 6.99% and 9.12%, respectively. However, as a whole, the Lehman Brothers Municipal Bond Index returned only 3.81% over the 12-month period. * Past performance is not a guarantee of future results.

A: After experiencing a sharper economic downturn than the nation in recent years, Colorado is now recovering at a healthy pace. The state's employment declines bottomed out in early 2004. In 2005, non-farm payroll employment grew over 2% even though manufacturing employment declined during that period. This is largely attributable to growth in construction, healthcare, and education. As of February 2006, Colorado's unemployment rate was 4.3%, which was below the national rate (source: Bureau of Labor Statistics). Colorado's tax revenues increased in recent years, with the growth due to increases in personal income tax, sales tax, and, most significantly, corporate income tax. Despite this growth, Colorado's Required Statutory Reserve was drawn down to $198 million in 2005. Voter initiatives, such as the Taxpayer Bill of Rights, have limited Colorado's financial flexibility. In November, Referendum C was approved by Colorado voters. This allows the state to retain tax revenue collected in excess of the fiscal years' budget for the next five years, estimated to be $3.7 billion. The Governor's 2006-2007 budget proposes a 4.1% increase over this year. Budget highlights include increased higher education and human services spending (source: Nelson A. Rockefeller Institute of Government and the Fiscal Survey of States-National Governor's Association). Q: How did the Fund perform versus its benchmark and peer group? A: Colorado Insured Municipal Income Fund returned 3.44%* (at net asset value with all distributions reinvested). By comparison, the Lipper Other States Municipal Debt Funds returned an average of 5.08% for the same period. The Fund's benchmark -- the national Lehman Brothers Municipal Bond Index -- returned 3.81% (source: Lipper). * Past performance is not a guarantee of future results. Substantially all dividends are exempt from federal income tax and may be subject to alternative minimum tax that applies to certain taxpayers. Capital gains, if any, are taxable. Q: What strategies affected Fund performance? A: As an insured Fund, we were largely excluded from the industrial development revenue bonds and pollution control revenue bonds IDR/PCR sector, which consists primarily of mid-to-low investment grade bonds. In addition, the industrial development revenue bonds and pollution control revenue bonds (IDR/PCR) sector includes tobacco bonds, which we have not invested in as an across-the-board policy in our municipal funds due to the volatility associated with this sub-sector. The IDR/PCR sector was by far the best performing segment in the Index, posting a +9.59% return for the period. When excluding tobacco bonds, the IDR/PCR sector returned only +3.82% over 12 months. The Fund underperformed the Lipper Peer Group because of our 100% investment in insured or equivalent AAA-rated bonds, though it should be noted that the Fund's Peer Group is not strictly an insured universe. The Fund was underweighted compared to the benchmark in BBB-rated and non-insured bonds. Over this 12-month period in the Lehman Municipal Bond Index, AAA-rated bonds returned just 3.65%. The A-rated bonds returned 4.19%, BBB-rated bonds returned 6.99%, and non-investment grade bonds posted a 9.12% return. Florida Insured Municipal Income Fund Q: What conditions prevailed in the Florida debt market? A: Florida ranks as the fourth most populous state in the nation and remains one of the nation's fastest growing states. This year showed that Florida's economy continues to be one of the strongest in the country, with rapid job and income growth. Despite another crippling hurricane season, which is magnified by Florida's reliance on tourism, Florida's job growth remained robust with non-farm payroll increasing 2.1% in 2005. The state's unemployment rate remains very low compared to the national average, at a mere 3.2% as of February 2006 (source: Bureau of Labor Statistics). (continued) 3 Portfolio management review Delaware Investments Closed-End Municipal Bond Funds Sales and use tax revenues, which account for approximately 60% of all taxes, grew 12% for fiscal 2005. At $988 million, Florida has one of the highest balances of any state in its budget stabilization fund. The $70.8 billion fiscal 2006 budget includes a 25% increase in the capital outlay budget, an economic development plan, funding of reserves, and $1.5 billion in tax cuts. The tax cuts proposed include the elimination of the intangibles tax and school property tax savings (source: Nelson A. Rockefeller Institute of Government and the Fiscal Survey of States-National Governor's Association). Q: How did the Fund perform versus its benchmark and peer group? A: Florida Insured Municipal Income Fund returned 2.76%* (at net asset value with all distributions reinvested). By comparison, the Lipper Florida Municipal Debt Funds gained an average of 4.84% for the same period. The Fund's benchmark -- the national Lehman Brothers Municipal Bond Index -- returned 3.81% (source: Lipper). Q: What strategies affected Fund performance? A: As an insured Fund, we were largely excluded from the industrial development revenue bonds and pollution control revenue bonds (IDR/PCR) sector, which is populated with mid-to-low investment grade bonds. In addition, the IDR/PCR sector includes tobacco bonds, which we have not invested in as an across-the-board policy in our municipal funds due to the volatility associated with this sub-sector. The IDR/PCR sector was by far the best performing segment in the Index, posting a +9.59% return for the period. When excluding tobacco bonds, the IDR/PCR sector returned only +3.82% over 12 months. The Fund underperformed the Lipper Peer Group because of our 100% investment in insured or equivalent AAA-rated bonds, though it should be noted that the Fund's Peer Group is not strictly an insured universe. The Fund was underweighted compared to the benchmark in BBB-rated and non-insured bonds. Over this 12-month period in the Lehman Brothers Municipal Bond Index, AAA-rated bonds returned just 3.65%, while A-rated bonds returned 4.19%, BBB-rated bonds returned 6.99%, and non-investment grade bonds posted a 9.12% return. Minnesota's Municipal Income Fund II Q: What conditions prevailed in the Minnesota debt market? A: Minnesota's new issuance totaled $7.6 billion in 2005 -- a 20% increase over 2004 (source: Municipal Market Data). Minnesota continues to recover from the 2001 recession, which resulted from its manufacturing sector concentration. The state has shown steady demographic trends, high personal income levels, and low unemployment (source: Nelson A. Rockefeller Institute of Government and the Fiscal Survey of States-National Governor's Association). While Minnesota's non-farm payroll continues to grow, it is now growing at a slower pace than the national average. Employment increased 1.04% in 2005 with gains in the services, construction, and manufacturing sectors (source: Bureau of Labor Statistics). However, Minnesota's unemployment rate remains below national levels at 4.4%. In 2005, tax revenues increased 7.7% due to double-digit growth in personal income tax revenues. Q: How did the Fund perform versus its benchmark and peer group? A: Minnesota Municipal Income Fund II returned 4.69%* (at net asset value with all distributions reinvested). Lipper recently moved the Fund into its Other States Municipal Debt peer group, which averaged a 5.08% gain during the year. The Lipper Other States category includes funds from other states, but its average may provide a better comparison than the now-closed Minnesota category that included just two other funds. The Fund's benchmark -- the national Lehman Brothers Municipal Bond Index -- gained 3.81% (source: Lipper). * Past performance is not a guarantee of future results. Substantially all dividends are exempt from federal income tax and may be subject to alternative minimum tax that applies to certain taxpayers. Capital gains, if any, are taxable. 4 (continued) Portfolio management review Delaware Investments Closed-End Municipal Bond Funds Q: What strategies affected Fund performance? A: One of the reasons the Fund underperformed other Minnesota closed-end funds was its underweighting in industrial development revenue bonds and pollution control revenue bonds (IDR/PCR) over the 12-month period. The IDR/PCR sector was by far the best performing segment in the Lehman Index, with a 9.59% return over the 12-month period. The IDR/PCR sector includes tobacco bonds, in which, as part of our management policy, we have chosen not to invest. Excluding tobacco bonds, the IDR/PCR sector returned only 3.82% over the 12-months. The Fund was also negatively affected by its weighting in pre-refunded bonds, which at times during the year accounted for as much as 20% of the Fund's total assets. When a bond becomes pre-refunded, a new bond is issued, and the proceeds are placed in escrow to be invested in U.S. Treasury securities. The proceeds generated are then used to pay the principal and interest on the pre-refunded bond. As such, these bonds typically receive the highest credit ratings and benefit from a price boost when they initially become pre-refunded. Because of their short-to-intermediate maturities, the price performance of this group was hurt during the 12-month period by the flattening of the yield curve, with shorter rates rising and longer rates remaining more stable. The Fund also experienced a number of calls on seasoned bonds with higher coupons and attractive embedded yields during the 12-month period. As portfolio managers, we must decide whether to sell these bonds early, forfeit the higher interest income, and realize a capital gain in order to seek better price performance. By holding on to the bonds, our strategy was often to let them mature or be called by the issuer. This generally affords us the opportunity to collect high income as long as possible while minimizing realized capital gains in the portfolios. In some environments, however, it does impede total return performance. 5 Performance summary Delaware Investments Arizona Municipal Income Fund Inc.

See accompanying notes 26 Notes to financial statements Delaware Investments Closed-End Municipal Bond Funds March 31, 2006 Delaware Investments Arizona Municipal Income Fund, Inc. ("Arizona Municipal Fund"); Delaware Investments Colorado Insured Municipal Income Fund, Inc. ("Colorado Insured Municipal Fund") and Delaware Investments Minnesota Municipal Income Fund II, Inc. ("Minnesota Municipal Fund II") are organized as Minnesota corporations and Delaware Investments Florida Insured Municipal Income Fund ("Florida Insured Municipal Fund") is organized as a Massachusetts Business Trust (each referred to as a "Fund" and collectively as the "Funds"). Arizona Municipal Fund, Florida Insured Municipal Fund and Minnesota Municipal Fund II are considered diversified closed-end management investment companies and Colorado Insured Municipal Fund is considered a non-diversified closed-end management investment company under the Investment Company Act of 1940, as amended. The Funds' common shares trade on the American Stock Exchange. The Funds' preferred shares are traded privately through a remarketing agent. The investment objective of each Fund is to provide high current income exempt from federal income tax and from the personal income tax of its state, if any, consistent with the preservation of capital. Florida Insured Municipal Fund will generally seek investments that will enable its shares to be exempt from Florida's intangible personal property tax. Each Fund will seek to achieve its investment objective by investing substantially all of its net assets in investment grade, tax-exempt municipal obligations of its respective state. 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 Directors/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. 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) for financial reporting purposes. 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 and pays dividends from net investment income monthly and distributions from net realized gain on investments, if any, annually. In addition, in order to satisfy certain distribution requirements of the Tax Reform Act of 1986, the Funds may declare special year-end dividend and capital gains distributions during November or December to shareholders of record on a date in such month. Such distributions, if received by shareholders by January 31, are deemed to have been paid by the Funds and received by shareholders on the earlier of the date paid or December 31 of the prior year. 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 expense offset shown as "expense paid indirectly." (continued) 27 Notes to financial statements Delaware Investments Closed-End Municipal Bond Funds 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 of 0.40%, which is calculated daily based on the average weekly net assets of each Fund, including assets attributable to any preferred stock that may be outstanding. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting and administration services. Effective May 19, 2005, the Funds pay DSC a monthly fee computed at the annual rate of 0.04% of the Funds' average daily net assets for accounting and administration services. Prior to May 19, 2005, the Funds paid DSC a monthly fee based on average net assets subject to certain minimums for accounting and administration services. At March 31, 2006, each Fund had liabilities payable to affiliates as follows: Arizona Colorado Insured Florida Insured Minnesota Municipal Municipal Municipal Municipal Fund Fund Fund Fund II Investment management fee payable to DMC $23,112 $38,137 $18,583 $88,695 Accounting administration and other expenses payable to DSC 4,024 15,224 4,842 16,607 Other expenses payable to DMC and affiliates* 1,852 2,880 663 16,402 *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, stock exchange fees, custodian fees and directors/trustees' fees. As provided in the investment management agreement, each Fund bears the cost of certain legal services expenses, including internal legal services provided by DMC employees. For the year ended March 31, 2006, each Fund was charged for internal legal services provided by DMC as follows: Arizona Colorado Insured Florida Insured Minnesota Municipal Municipal Municipal Municipal Fund Fund Fund Fund II $2,781 $4,673 $2,111 $7,246 Certain officers of DMC and DSC are officers and/or directors/trustees of the Funds. These officers and directors/trustees are paid no compensation by the Funds. 3.

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 March 31, 2006 and 2005 was as follows: Arizona Colorado Insured Florida Insured Minnesota Municipal Municipal Municipal Municipal Fund Fund Fund Fund II Year Ended March 31, 2006 Tax-exempt income $3,261,410 $5,673,140 $2,839,838 $8,676,141 Long-term capital gain 64,461 174,385 723,317 -- ---------- ---------- ---------- ---------- Total $3,325,871 $5,847,525 $3,563,155 $8,676,141 ========== ========== ========== ========== Year Ended March 31, 2005 Tax-exempt income $3,210,970 $5,245,675 $2,745,766 $8,535,622 Ordinary income 84,725 14,636 -- 6,890 Long-term capital gain 56,464 143,726 261,818 -- ---------- ---------- ---------- ---------- Total $3,352,159 $5,404,037 $3,007,584 $8,542,512 ========== ========== ========== ========== As of March 31, 2006, the components of net assets on a tax basis were as follows: Arizona Colorado Insured Florida Insured Minnesota Municipal Municipal Municipal Municipal Fund Fund Fund Fund II Shares of beneficial interest $40,838,893 $67,238,110 $33,361,389 $158,785,529 Undistributed tax-exempt income 330,793 938,459 422,158 969,303 Undistributed long-term gains -- 237,031 107,270 -- Capital loss carryforwards (30,981) -- -- (533,589) Unrealized appreciation of investments 2,784,644 5,419,262 1,601,391 10,259,376 ----------- ----------- ----------- ------------ Net assets $43,923,349 $73,832,862 $35,492,208 $169,480,619 =========== =========== =========== ============ 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 dividends and distributions and market discount on certain debt instruments. Results of operations and net assets were not affected by these reclassifications. For the year ended March 31, 2006, the Funds recorded the following reclassifications. Arizona Colorado Insured Municipal Municipal Fund Fund Undistributed net investment income $(11,165) $(52,449) Accumulated net realized gains (losses) 11,165 52,449 (continued) 29 Notes to financial statements Delaware Investments Closed-End Municipal Bond Funds 4. Dividend and Distribution Information (continued) For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. Capital loss carryforwards remaining at March 31, 2006 will expire as follows: Arizona Colorado Insured Municipal Municipal Fund Fund 2008 $ -- $339,543 2009 -- 175,804 2010 -- 8,416 2013 -- 9,826 2014 30,981 -- ------- -------- Total $30,981 $533,589 ======= ======== In 2006, Minnesota Municipal Fund II utilized $241,692 of capital loss carryforwards. 5. Capital Stock Pursuant to their articles of incorporation, Arizona Municipal Fund, Colorado Insured Municipal Fund and Minnesota Municipal Fund II each have 200 million shares of $0.01 par value common shares authorized. Florida Insured Municipal Fund has been authorized to issue an unlimited amount of $0.01 par value common shares. The Funds did not repurchase any shares under the Share Repurchase Program during the year ended March 31, 2006. Shares issuable under the Funds' dividend reinvestment plan are purchased by the Funds' transfer agent, Mellon Investor Services, LLC, in the open market. For the year ended March 31, 2006, Arizona Municipal Fund, Colorado Insured Municipal Fund and Florida Insured Municipal Fund did not have any transactions in common shares. Minnesota Municipal Income Fund II issued common shares in accordance with the reorganizations described in Note 6 below. The Funds each have one million shares of $0.01 par value preferred shares authorized, except for Florida Insured Municipal Fund, which has an unlimited amount of $0.01 par value preferred shared authorized. On May 14, 1993, Arizona Municipal Fund and Florida Insured Municipal Fund issued 500 and 400 preferred shares, respectively. Also on that date, Minnesota Municipal Fund II issued 600 Series A and 600 Series B preferred shares. On September 23, 1993, Colorado Insured Municipal Fund issued 800 preferred shares. The preferred shares of each Fund have a liquidation preference of $50,000 per share plus an amount equal to accumulated but unpaid dividends. In connection with the reorganizations described in Note 6 below, shareholders of Minnesota Municipal Fund II approved amendments to its charter to create two new series to absorb the preferred stock of Minnesota Municipal Fund and Minnesota Municipal Fund III. These new series have identical rights and preferences (including liquidation rights) in all material respects to the preferred shares of Minnesota Municipal Fund and Minnesota Municipal Fund III, and are substantially similar to the Series A and B preferred shares of Minnesota Municipal Fund II with respect to their preferences, voting powers, restrictions, limitation as to dividends, qualifications, liquidation rights, and term and conditions of redemption. Minnesota Municipal Fund II issued 400 Series C Preferred Shares to preferred shareholders of Minnesota Municipal Fund in exchange for that Fund's preferred shares and 300 Series D Preferred Shares to preferred shareholders of Minnesota Municipal Fund III in exchange for that Fund's preferred shares at the close of the reorganization on February 24, 2006. Dividends for the outstanding preferred shares of each Fund are cumulative at a rate established at the initial public offering and are typically reset every 28 days based on the results of an auction. Dividend rates (adjusted for any capital gain distributions) ranged during the year ended March 31, 2006 as follows: Fund Low High ---- ---- ---- Arizona Municipal Fund 2.10% to 3.40% Colorado Insured Municipal Fund 1.00% to 3.90% Florida Insured Municipal Fund 2.10% to 7.00% Minnesota Municipal Fund II 1.75% to 3.40% Citigroup Global Markets, Inc. (formerly Salomon Smith Barney, Inc.), and Merrill Lynch Pierce, Fenner & Smith Inc. (Colorado Insured Municipal Fund only), as the remarketing agents, receive an annual fee from each of the Funds of 0.25% of the average amount of preferred stock outstanding. 30 (continued) Notes to financial statements Delaware Investments Closed-End Municipal Bond Funds 5. Capital Stock (continued) Under the 1940 Act, the Funds may not declare dividends or make other distributions on common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred stock is less than 200%. The preferred shares are redeemable at the option of the Funds, in whole or in part, on any dividend payment date at $50,000 per share plus any accumulated but unpaid dividends whether or not declared. The preferred shares are also subject to mandatory redemption at $50,000 per share plus any accumulated but unpaid dividends whether or not declared, if certain requirements relating to the composition of the assets and liabilities of each Fund are not satisfied. The holders of preferred shares have voting rights equal to the holders of common shares (one vote per share) and will vote together with holders of common shares as a single class. However, holders of preferred shares are also entitled to elect two of each Fund's Directors. In addition, the 1940 Act requires that along with approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the preferred shares, and (b) take any action requiring a vote of security holders pursuant to Section 13(a) of the 1940 Act, including, among other things, changes in each of the Fund's subclassificiation as a closed-end investment company or (c) changes in their fundamental investment restrictions. 6. Fund Reorganizations At the close of business on February 24, 2006, Minnesota Municipal Fund II acquired substantially all of the assets of Delaware Investments Minnesota Municipal Income Fund, Inc. ("Minnesota Municipal Fund") and Delaware Investments Minnesota Municipal Income Fund III, Inc. ("Minnesota Municipal Fund III"), each pursuant to an Agreement and Plan of Acquisition (the "Reorganizations"). The common shareholders of Minnesota Municipal Fund and Minnesota Municipal Fund III each received common shares of Minnesota Municipal Fund II equal to the aggregate net asset value of their respective shares prior to the Reorganization. The preferred shareholders of Minnesota Municipal Fund and Minnesota Municipal Fund III received the same number of Series C and Series D preferred shares, respectively, of Minnesota Municipal Fund II as they held in their respective funds prior to the Reorganization (see Note 5). The Reorganizations were treated as non-taxable events and, accordingly, Minnesota Municipal Fund II'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 Minnesota Municipal Fund and Minnesota Municipal Fund III as of the close of business on February 24, 2006, were as follows: Net Unrealized Accumulated Net Net Assets Appreciation Realized Gain/Loss ---------- -------------- ------------------ Minnesota Municipal Fund $38,077,404 $2,648,640 $ 2,145 Minnesota Municipal Fund III 25,566,621 1,999,455 (81,744) The net assets of Minnesota Municipal Fund II prior to the Reorganizations were $108,531,274. The combined net assets of Minnesota Municipal Fund II after the Reorganization were $172,175,299. Minnesota Municipal Fund II will continue to trade and to be listed on the American Stock Exchange. Beginning on February 27, 2006 and going forward, however, Minnesota Municipal Fund and Minnesota Municipal Fund III will no longer trade or be listed on the American Stock Exchange, and their corporate existence will be liquidated and dissolved. In January 2007, shareholders of Minnesota Municipal Fund and Minnesota Municipal Fund III will receive Form 1099-DIV that will report the amount and character of each Fund's distributions paid in calendar year 2006. Common and preferred shares of Minnesota Municipal Fund II issued to shareholders of Minnesota Municipal Fund and Minnesota Municipal Fund III in connection with the Reorganizations were as follows: Common Exchange Preferred Exchange Shares Issued Ratio Shares Issued Ratio ------------- ---------- ------------- -------- Minnesota Municipal Fund 2,543,581 1.02 to 1 400 1 to 1 Minnesota Municipal Fund III 1,709,194 1.08 to 1 300 1 to 1 7. Credit and Market Risk The Funds use leverage in the form of preferred shares. Leveraging may result in a higher degree of volatility because each Fund's net asset value could be more sensitive to fluctuations in short-term interest rates and changes in market value of portfolio securities attributable to the leverage. 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. The Funds 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 identified on the Statements of Net Assets. (continued) 31 Notes to financial statements Delaware Investments Closed-End Municipal Bond Funds 7. Credit and Market Risk (continued) 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 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 that 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 Investors Service, Inc., Standard & Poor's Ratings Group, and/or Fitch due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement. 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. While maintaining oversight, each Fund's Board of Directors/Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of each Fund's limitation on investments in illiquid assets. At March 31, 2006, there were no Rule 144A securities and no securities have been determined to be illiquid under the Funds' Liquidity Procedures. 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 the Funds' 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 March 31, 2006, 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) ------------- ------------- ------------- Arizona Municipal Fund 2% 98% 100% Colorado Insured Municipal Fund 3% 97% 100% Florida Insured Municipal Fund 20% 80% 100% Minnesota Municipal Fund II -- 100% 100% (A) and (B) are based on a percentage of each Fund's total distributions. 32 Report of independent registered public accounting firm To the Shareholders and Board of Directors/Trustees Delaware Investments Arizona Municipal Income Fund, Inc. Delaware Investments Colorado Insured Municipal Income Fund, Inc. Delaware Investments Florida Insured Municipal Income Fund Delaware Investments Minnesota Municipal Income Fund II, Inc. We have audited the accompanying statements of net assets of Delaware Investments Arizona Municipal Income Fund, Inc., Delaware Investments Colorado Insured Municipal Income Fund, Inc., Delaware Investments Florida Insured Municipal Income Fund and Delaware Investments Minnesota Municipal Income Fund II, Inc. (the "Funds"), as of March 31, 2006, 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, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2006, by correspondence with the custodian and brokers. 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 respective Funds at March 31, 2006, 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 May 12, 2006 33 Other fund information Delaware Investments Closed-End Municipal Bond Funds The shareholders of Delaware Investments Minnesota Municipal Income Fund II, Inc.

The Adviser has established a Proxy Voting Committee (the "Committee") which is responsible for overseeing the Adviser's proxy voting process for the registrant. One of the main responsibilities of the Committee is to review and approve the Procedures to ensure that the Procedures are designed to allow the Adviser to vote proxies in a manner consistent with the goal of voting in the best interests of the registrant. In order to facilitate the actual process of voting proxies, the Adviser has contracted with Institutional Shareholder Services ("ISS") to analyze proxy statements on behalf of the registrant and other Adviser clients and vote proxies generally in accordance with the Procedures. The Committee is responsible for overseeing ISS's proxy voting activities. If a proxy has been voted for the registrant, ISS will create a record of the vote. By no later than August 31 of each year, information (if any) regarding how the registrant voted proxies relating to portfolio securities during the most recently disclosed 12-month period ended June 30 is available without charge (i) through the registrant's website at http://www.delawareinvestments.com; and (ii) on the Commission's website at http://www.sec.gov. The Procedures contain a general guideline that recommendations of company management on an issue (particularly routine issues) should be given a fair amount of weight in determining how proxy issues should be voted. However, the Adviser will normally vote against management's position when it runs counter to its specific Proxy Voting Guidelines (the "Guidelines"), and the Adviser will also vote against management's recommendation when it believes that such position is not in the best interests of the registrant. As stated above, the Procedures also list specific Guidelines on how to vote proxies on behalf of the registrant. Some examples of the Guidelines are as follows: (i) generally vote for shareholder proposals asking that a majority or more of directors be independent; (ii) generally vote against proposals to require a supermajority shareholder vote; (iii) votes on mergers and acquisitions should be considered on a case-by-case basis, determining whether the transaction enhances shareholder value; (iv) generally vote against proposals to create a new class of common stock with superior voting rights; (v) generally vote re-incorporation proposals on a case-by-case basis; (vi) votes with respect to equity-based compensation plans are generally determined on a case-by-case basis; and (vii) generally vote for proposals requesting reports on the level of greenhouse gas emissions from a company's operations and products. Because the registrant has delegated proxy voting to the Adviser, the registrant is not expected to encounter any conflict of interest issues regarding proxy voting and therefore does not have procedures regarding this matter. However, the Adviser does have a section in its Procedures that addresses the possibility of conflicts of interest. Most proxies which the Adviser receives on behalf of the registrant are voted by ISS in accordance with the Procedures. Because almost all registrant proxies are voted by ISS pursuant to the pre-determined Procedures, it normally will not be necessary for the Adviser to make an actual determination of how to vote a particular proxy, thereby largely eliminating conflicts of interest for the Adviser during the proxy voting process. In the very limited instances where the Adviser is considering voting a 43 proxy contrary to ISS's recommendation, the Committee will first assess the issue to see if there is any possible conflict of interest involving the Adviser or affiliated persons of the Adviser. If a member of the Committee has actual knowledge of a conflict of interest, the Committee will normally use another independent third party to do additional research on the particular proxy issue in order to make a recommendation to the Committee on how to vote the proxy in the best interests of the registrant. The Committee will then review the proxy voting materials and recommendation provided by ISS and the independent third party to determine how to vote the issue in a manner which the Committee believes is consistent with the Procedures and in the best interests of the registrant.
