(C)2006 Delaware Distributors, L.P. - -------------------------------------------------------------------------------- Disclosure For the Period September 1, 2005 to February 28, 2006 - -------------------------------------------------------------------------------- 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 September 1, 2005 to February 28, 2006. 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 return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use 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 the tables 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 181/365 (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 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, 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%. 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) 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 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 and on the Statements of Operations with the corresponding expense offset shown as "expense paid indirectly." 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 Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- On the first $500 million 0.500% 0.550% 0.550% On the next $500 million 0.475% 0.500% 0.500% On the next $1.5 billion 0.450% 0.450% 0.450% In excess of $2.5 billion 0.425% 0.425% 0.425% 24 - -------------------------------------------------------------------------------- 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.

(DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. 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. 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 February 28, 2006, each Fund had liabilities payable to affiliates as follows: Delaware Tax-Free Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- Investment management fees payable to DMC $ 40,979 $ 30,260 $115,160 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 25,433 14,404 46,537 Distribution fees payable to DDLP 33,834 32,361 57,992 Other expenses payable to DMC and affiliates* 9,315 3,997 10,792 * 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. 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 six months ended February 28, 2006, Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund were charged $5,887, $3,421, and $10,518, respectively, for internal legal services provided by DMC. For the six months ended February 28, 2006, DDLP earned commissions on sales of Class A shares for each Fund as follows: Delaware Tax-Free Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- $ 9,670 -- $ 16,132 For the six months ended February 28, 2006, DDLP received gross contingent deferred sales charge commissions on redemption of each Fund's Class A, Class B and Class C shares. 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 Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- Class A $ -- $ 115 $ -- Class B 7,312 9,719 3,112 Class C 238 288 102 Certain officers of DMC, DSC and DDLP are officers and/or trustees of the Trust.

Investments For the six months ended February 28, 2006, the Funds made purchases and sales of investment securities other than short-term investments as follows: Delaware Tax-Free Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- Purchases $ 5,528,545 $11,613,595 $ 10,552,215 Sales 6,926,122 3,535,395 15,020,123 At February 28, 2006, the cost of investments for federal income tax purposes has been estimated since the final tax characteristics cannot be determined until the fiscal year end. At February 28, 2006, the cost of investments and unrealized appreciation (depreciation) for each Fund were as follows: Delaware Tax-Free Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- Cost of investments $149,094,216 $93,044,160 $263,396,739 ============ =========== ============ Aggregate unrealized appreciation $ 8,492,598 $ 4,556,041 $ 17,251,688 Aggregate unrealized depreciation (40,355) (57,928) (173,400) ------------ ----------- ------------ Net unrealized appreciation $ 8,452,243 $ 4,498,113 $ 17,078,288 ============ =========== ============ 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 six months ended February 28, 2006 and the year ended August 31, 2005 was as follows: Delaware Tax-Free Delaware Tax-Free Delaware Tax-Free Arizona Insured Fund California Fund Colorado Fund -------------------- ----------------- ----------------- Six Months Ended 2/28/06* Tax-exempt income $ 3,136,845 $ 1,708,466 $ 6,161,580 Year Ended 8/31/05 Tax-exempt income $ 5,887,149 $ 2,275,968 $ 12,970,896 Long-term capital gain 261,925 -- -- ------------ ----------- ------------ Total $ 6,149,074 $ 2,275,968 $ 12,970,896 ============ =========== ============ * Tax information for the period ended February 28, 2006 is an estimate and the tax character of dividends and distributions may be redesignated at fiscal year end.

Post-October losses represent losses realized on investment transactions from November 1, 2005 through February 28, 2006 that, in accordance with federal income tax regulations, the Fund has elected to defer and treat as having arisen in the following fiscal year. 26 - -------------------------------------------------------------------------------- Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 4. 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 six months ended February 28, 2006, the Fund recorded an estimate of these differences since the final tax characteristics cannot be determined until fiscal year end.

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)* Delaware Tax-Free California Insured Fund 31,492,746 1,782,779 -- * 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 $225,000,000 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 February 28, 2006, or at any time during the period. 28 - -------------------------------------------------------------------------------- Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 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 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 Rating Group, 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. While maintaining oversight, each Fund's Board of 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 February 28, 2006, there were no Rule 144A securities and no securities have been determined to be illiquid under the Funds' Liquidity Procedures. 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 the Funds' existing contracts and expects the risk of loss to be remote. 29 - -------------------------------------------------------------------------------- About - -------------------------------------------------------------------------------- THE ORGANIZATION This semiannual report is for the information of Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for Delaware Tax-Free Arizona Insured Fund, Delaware Tax-Free California Fund and Delaware Tax-Free Colorado Fund and the Delaware Investments(R) Performance Update for the most recently completed calendar quarter. The prospectus sets forth details about charges, expenses, investment objectives, and operating policies of the Funds. You should read the prospectus carefully before you invest. The figures in this report represent past results that are not a guarantee of future results. The return and principal value of an investment in each Fund will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Board of Trustees Jude T.

(C)2006 Delaware Distributors, L.P. - -------------------------------------------------------------------------------- Disclosure For the Period September 1, 2005 to February 28, 2006 - -------------------------------------------------------------------------------- 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 September 1, 2005 to February 28, 2006. 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 ratios and an assumed rate of return of 5% per year before expenses, which is not the Funds' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use 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 the tables reflect fee waivers in effect.

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 twelve 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. 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 the Funds on the basis of "settled shares" of each class in relation to the net assets of the Funds. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Funds 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) 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 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 expense offset shown as "expense paid indirectly." 32 - -------------------------------------------------------------------------------- Delaware Minnesota Municipal Bond Funds Notes - -------------------------------------------------------------------------------- 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 Delaware Tax-Free Delaware Minnesota Delaware Tax-Free Minnesota Minnesota High-Yield Minnesota Fund Insured Fund Intermediate Fund Municipal Bond Fund ----------------- ----------------- ----------------- ------------------- On the first $500 million 0.550% 0.500% 0.500% 0.550% On the next $500 million 0.500% 0.475% 0.475% 0.500% On the next $1.5 billion 0.450% 0.450% 0.450% 0.450% In excess of $2.5 billion 0.425% 0.425% 0.425% 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.

Dividend and Distribution Information (continued) The components of net assets are estimated since final tax characteristics cannot be determined until fiscal year end. As of February 28, 2006, the estimated components of net assets on a tax basis were as follows: Delaware Tax-Free Delaware Tax-Free Delaware Minnesota Delaware Tax-Free Minnesota Minnesota High-Yield Minnesota Fund Insured Fund Intermediate Fund Municipal Bond Fund ----------------- ----------------- ----------------- ------------------- Shares of beneficial interest $384,593,993 $222,056,876 $55,733,282 $100,491,739 Undistributed tax-exempt income 147,934 -- -- 294 Undistributed long-term capital gain 139,580 (10,836) -- -- Capital loss carryforwards -- -- (1,275,535) (2,433,778) Six month period realized gains (losses) -- -- (81,340) 32,009 Post-October losses -- (102,400) (31,034) -- Unrealized appreciation of investments 18,751,299 16,783,462 2,058,024 2,405,589 ------------ ------------ ----------- ------------ Net assets $403,632,806 $238,727,102 $56,403,397 $100,495,853 ============ ============ =========== ============ 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 and premium on debt instruments. Post-October losses represent losses realized on investment transactions from November 1, 2005 through February 28, 2006 that, in accordance with federal income tax regulations, each Fund has elected to defer and treat as having arisen in the following fiscal year. 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 six months ended February 28, 2006, the Funds recorded an estimate of these differences since the final tax characteristics cannot be determined until fiscal year end.

Line of Credit Each Fund, along with certain other funds in the Delaware Investments Family of Funds (the "Participants"), participates in a $225,000,000 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 February 28, 2006, or at any time during the period. 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. 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. The Funds 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 Investors Service, Inc., Standard & Poor's Rating Group, 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. While maintaining oversight, each Fund's Board of 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 February 28, 2006, there were no Rule 144A securities. Illiquid securities have been identified on the Statements of Net 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. 37 - -------------------------------------------------------------------------------- About - -------------------------------------------------------------------------------- THE ORGANIZATION This semiannual report is for the information of 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 shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for 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 and the Delaware Investments(R) Performance Update for the most recently completed calendar quarter.
